The push-out assembly 60 and the relationship between the push-out assembly 60 and the plug assembly 10, the housing 20 and the paddle 30 are described below in conjunction with Figures 5 and 6. Describe the connection relationship.

FIG. 5 shows a partially disassembled schematic diagram of a charging device provided by an embodiment of the present application. As shown in Figure 5, the push-out assembly 60 includes a lever 61 and a first conversion structure 62; the lever 61 is rotationally connected to the housing 20; the lever 61 is connected to the plug assembly 10 through the first conversion structure 62, and the first conversion structure 62 It is used to convert the rotational motion of the lever 61 into the linear movement of the plug assembly 10; when the lever 61 rotates relative to the housing 20, the first conversion structure 62 can drive the plug assembly 10 to slide relative to the housing 20 to slide to the housing. 20 or retreat into the housing 20 .

As shown in FIG. 5 , in some embodiments, plug assembly 10 includes plug 11 , and boss 14 . Among them, the plug 11 is used to be inserted into a universal connector; the boss 14 is used to provide structural components and cooperate with components in the charging device to achieve extension and retraction of the plug 11 relative to the housing.

As shown in Figure 5, in some embodiments, the first conversion structure 62 includes a first guide hole 621 and a first guide post 622; the first guide hole 621 is provided on the lever 61, and the first guide post 622 is provided on the plug. 11 on. The first guide hole 621 extends along the radial direction a-a’ of the rotational motion trajectory of the lever 61.

FIG. 6 is a schematic structural diagram of the charging device shown in FIG. 5 after assembly. 5 and 6 together, the first guide hole 621 is passed through the first guide post 622. When the lever 61 rotates, the first guide post 622 can move along the first guide hole 621 in the first guide hole 621. Slide in the extension direction to drive the plug 11 to move linearly. Among them, due to the contact fit between the first guide hole 621 and the first guide post 622, the side wall of the first guide hole 621 will give the first guide post 622 a driving force due to the rotation power of the lever 61, so that the first guide post 622 will 622 can drive the plug 11 to move linearly in the direction of the driving force. For example, when pushing the paddle 30 in the retraction direction as shown in FIG. 6 , the side wall of the first guide hole 621 will give the first guide post 622 a pushing force F due to the power of the rotation of the push rod 61 . The pushing force F The direction is consistent with the direction of linear movement of the pick 30, and the driving force F drives the plug 11 to move linearly in the direction of the driving force F. The hole-column matching method is highly reliable, has a simple structure, occupies a small space, and can meet the small-size installation requirements of the charging device.

In some embodiments, the first guide hole 621 is provided on the plug 11 , and the first guide post 622 is provided on the lever 61 . The first guide hole 621 extends along the radial direction a-a’ of the rotational motion trajectory of the lever 61.

In some embodiments, the first conversion structure 62 includes an intermeshing gear and a rack. The gear is disposed on the lever 61 and the rack is disposed on the plug 11 .

Continuing to refer to FIG. 5 , in some embodiments, the pushing assembly 60 further includes a first elastic member 63 , one end of which is fixedly connected to the lever 61 , and the other end of which is fixedly connected to the housing 20 . It should be noted that the first elastic member 63 is connected to the rotating end of the lever 61, so that when the lever 61 rotates, the first elastic member 63 can deform, thereby storing or releasing energy.

5 and 6 together, when the plug 11 slides toward the outside of the housing 20, the lever 61 rotates in the first direction, and the first elastic member 63 is stretched and deformed; when the plug 11 retreats toward the inside of the housing 20 , the lever 61 rotates in the second direction opposite to the first direction, and the stretched first elastic member 63 gradually recovers its deformation; when the lever 61 drives the plug 11 to retreat into the charging device, when the plug 11 still has a small When the first elastic member 63 is partially located outside the housing 20, the first elastic member 63 can drive the lever 61 to continue to rotate due to the elastic force generated by the gradual recovery of deformation, so as to drive the plug 11 to completely retreat into the housing. The first direction may be the opposite direction of the retreat direction as shown in FIG. 6 , and the second direction may be the retreat direction as shown in FIG. 6 .

In a possible implementation, the first elastic member 63 may be a torsion spring. The torsion spring can store and release angular energy, which can provide pressing force and damping effect to the lever. In addition, during the process of pushing out the pick 30, the torsion spring can be used to adjust the difficulty of pushing out.

The connection relationship between the push-out component 60 and the plug 11 and the housing 20 has been described above. The connection relationship between the push-out component 60 and the paddle 30 will be described below.

Please continue to refer to Figure 6. The paddle 30 is connected to the lever 61 through a second conversion structure 64. The second conversion structure 64 is used to convert the linear movement of the paddle 30 into a rotational movement of the lever 61; the paddle 30 is relative to the shell. When the body 20 slides, the second conversion structure 64 can drive the lever 61 to rotate relative to the housing 20 . The paddle 30 is used to control the sliding of the lever 61, thereby realizing the rotation of the lever 61 relative to the housing 20. In this way, the plug 11 can be controlled to slide relative to the housing 20 only by pushing the paddle 30, thereby improving user convenience. Experience.

As shown in Figure 6, in one embodiment, the second conversion structure 64 includes a paddle guide groove 641 and a second guide post 642. The second guide post 642 is provided on the paddle 61, and the paddle guide groove 641 is provided on Pick 30 on. The extension direction b-b' of the paddle guide groove 641 is consistent with the sliding direction of the plug 11; the paddle guide groove 641 is disposed on the second guide post 642. When the paddle 30 moves linearly, the paddle guide groove 641 The side wall pushes the second guide post 642 to move together, so that the second guide post 642 can slide in the paddle guide groove 641 along the extension direction b-b' of the paddle guide groove 641. Due to the relationship between the paddle 61 and the housing 20 The second guide post 642 can drive the lever 61 to rotate relative to the housing 20 , thereby converting the linear motion of the paddle 30 into the rotational motion of the lever 61 .

In some embodiments, the paddle guide groove 641 is opened on the first end 311 .

In some embodiments, the position where the paddle 30 and the paddle 61 are connected through the second conversion structure 64 is closer to the position where the paddle 61 and the plug 11 are connected through the first conversion structure 62 than the position where the paddle 61 and the housing 20 rotate. The location of the connection. That is, as shown in Figure 7, the distance Q between the position where the paddle 30 and the paddle 61 are connected through the second conversion structure 64 and the position where the paddle 61 is rotationally connected to the housing 20; the paddle 61 and the plug 11 pass through the first The distance W between the position where the conversion structure 62 is connected and the position where the lever 61 is rotationally connected to the housing 20 is smaller than the distance W. The distance Q is smaller than the distance W.

It can be understood that the pushing distance of the paddle 30 can be adjusted by the lever ratio of the lever 61 , which is the distance Q between the fixing hole 613 of the paddle 30 and the second guide post 642 , and the length W of the lever 61 ratio. When the paddle 30 slides relative to the housing 20, since the lever 61 rotates relative to the housing 20, the greater the distance between the lever 61 and the position where the lever 61 is rotationally connected to the housing 20, the greater the linear displacement. Therefore, the linear displacement of the position where the lever 61 is connected to the plug 11 is greater than the linear displacement of the position where the lever 30 is connected to the lever 61 . In this way, the pick 30 moves a smaller distance, so that the plug 11 can move larger, which can make the operation more labor-saving.

In some embodiments, the second guide post 642 is provided on the paddle 30 , and the paddle guide groove 641 is provided on the paddle 61 .

Please continue to refer to FIGS. 5 and 6 . In some embodiments, the housing 20 includes a lever bracket 23 , a first installation cavity 231 is formed in the lever bracket 23 , and the plug assembly 10 is disposed in the first installation cavity 231 . The piece 30 is arranged outside the lever bracket 23; the lever bracket 23 is provided with a guide groove 232, and the extension direction of the guide groove 232 is consistent with the sliding direction of the plug 11; the first guide post 622 extends through the guide groove 232 to the first In the guide hole 621 , the first guide post 622 can slide along the extension direction of the guide groove 232 . By providing the guide groove 232, when the first guide post 622 slides relative to the first guide hole 621, the first guide post 622 also slides in the guide groove 232, thereby ensuring that the plug 11 moves linearly driven by the first guide hole 621. .

In one implementation, the length of the guide groove 232 is limited according to the length of the plug 11 extending out of the charging device, thereby guiding the first guide post 622 and preventing over-pushing. In addition, by limiting the length of the guide groove 232, it is also ensured that when the plug 11 moves to the end point, the first guide post 622 contacts the guide groove 232, thus preventing the plug 11 from being in an empty position after being pushed into place, causing the plug 11 to shake.

And, in some embodiments, one end of the lever 61 is fixed on the lever bracket 23 by riveting.

In one implementation, the first elastic member 63 can be fixed on the lever bracket 23 by riveting.

Please continue to refer to FIG. 5 . In one implementation, the pick 30 further includes a pick body 32 ; the pick body 32 is disposed on the pick bracket 31 and is fixedly connected to the pick bracket 31 . In this way, by pushing the pick body 32, the pick bracket 31 is driven to move together.

In one implementation, the pick body 32 and the pick bracket 31 can be fixed together by dispensing glue.

The TWS charging device provided by this application not only realizes wireless charging, but also realizes the extension and retraction of the plug 11. In this way, when the charging device itself is in an uncharged state, the plug 11 retracts into the TWS charging device and starts charging. To protect the plug 11. During the entire movement, the range of movement of each component is small and the structure of each component is compact, thereby maximizing the use of the space of the charging device.

When the plug 11 of the plug assembly 10 is inserted into the charging head, resistance will be encountered in the opposite direction along the insertion direction, and the plug 11 may retreat due to the resistance. In order to solve the possible retraction problem of the plug 11, the charging device provided by the embodiment of the present application is also provided with a self-locking structure 70. The structure of the self-locking structure 70 will be described below with reference to the accompanying drawings.

FIG. 8 shows a partially disassembled schematic diagram of another charging device provided by an embodiment of the present application. As shown in FIG. 8 , the charging device also includes: a self-locking structure 70 through which the plug 11 is connected to the housing 20 ; and an unlocking structure 80 through which the plug 11 is connected to the paddle 30 .

FIG. 10 is a schematic structural diagram of the self-locking structure of the charging device shown in FIG. 8 . Referring to FIGS. 8 and 10 , in some embodiments, the self-locking structure 70 includes: a self-locking guide post hole 71 , a self-locking guide post 74 and a second elastic member 72 . The self-locking guide post hole 71 is opened in the housing 20; the extension direction c-c' of the self-locking guide post 74 is perpendicular to the direction of linear movement of the plug 11. The self-locking guide post 74 is connected to the plug 11 through a second elastic member 72. After the plug 11 slides out of the housing 20, the second elastic member 72 is used to provide an elastic force perpendicular to the direction of linear movement of the self-locking guide post 74 and the plug 11. , so that the self-locking guide post 74 is inserted into the self-locking guide post hole 71 . When the pick 30 is in the starting position, that is, the plug 11 is located in the housing 20, the second elastic member 72 is in a compressed state. Push the paddle 30 in the pushing direction until the plug 11 extends out of the housing 20, the second elastic member 72 gradually releases its compression, and the self-locking guide post 74 is gradually inserted into the self-locking guide post hole 71. Inside.

In one implementation, the side wall of the plug 11 is provided with a cavity 12 as shown in FIG. 8 , and a guide post 13 opposite to the second elastic member 72 of the self-locking structure 70 is provided in the cavity 12 . The guide post 13 To achieve pre-compression of the second elastic member 72 .

Please refer to Figures 8 and 10. In some embodiments, the self-locking structure 70 also includes: a guide post pressure block 73, which is connected to the plug 11. The guide post pressure block 73 has a guide hole; the self-locking guide post 74 is passed through the guide post. In the hole, the self-locking guide post 74 is slidingly connected to the guide post pressing block 73 , so that the self-locking guide post 74 moves in a direction perpendicular to the direction of linear motion of the plug 11 under the elastic force of the second elastic member 72 .

In other embodiments, the self-locking guide post hole 71 can be opened in the plug 11 , and the self-locking guide post 74 can be connected to the housing 20 through the second elastic member 72 .

FIG. 9 is a schematic structural diagram of the charging device shown in FIG. 8 after assembly. As shown in FIG. 9 , after the plug 11 slides out of the housing 20 , the plug 11 is locked with the housing 20 through the self-locking structure 70 , so that the plug 11 and the housing 20 are in an interlocked state. Specifically, please refer to Figures 8 and 9. When the plug 11 slides out of the housing 20, the self-locking guide post 74 in the self-locking structure 70 is inserted into the self-locking guide post hole 71, thereby realizing the connection between the plug 11 and the housing 20. of interlocking.

Please continue to refer to FIGS. 8 and 9 . When the plug 11 retreats into the housing 20 , the unlocking structure 80 is used to unlock the plug 11 and the housing 20 in an interlocked state.

In some embodiments, the unlocking structure 80 includes: a paddle unlocking groove 82 and an unlocking guide post 81; the paddle unlocking groove 82 is provided on the paddle 30, and the extension direction of the paddle unlocking groove 82 is consistent with the direction of linear movement of the plug 11 ; The unlocking guide post 81 is fixedly connected to the self-locking guide post 74 and is inserted into the paddle unlocking groove 82; wherein, the paddle unlocking groove 82 has a slope 821. When the paddle drives the plug 11 to retreat, the slope 821 guides the unlocking. The force F′ of the column 81 perpendicular to the linear movement direction of the plug 11 overcomes the elastic force of the second elastic member 72 to the self-locking guide column 74, so that the self-locking guide column 74 is pulled out from the self-locking guide column hole 71.

In some embodiments, the paddle unlocking slot 82 is formed on the second end 312 .

The above describes the connection relationship and relative position relationship between the components of the charging device provided by the embodiment of the present application. In order to more clearly explain the working principle of the plug of the charging device during the process of pushing out and retracting provided by the embodiment of the present application, the movement trajectories of each component of the plug of the charging device during the process of pushing out and retracting will be described in detail below with reference to the accompanying drawings. .

Figure 11a shows a schematic cross-sectional view of A-A of a charging device provided by an embodiment of the present application. Figure 11b is a B-B cross-sectional schematic diagram of the charging device shown in Figure 11a. 11a and 11b together, when the plug assembly 10 is in the initial state, that is, when the plug 11 is all in the charging device, the guide post pressure block 73 is fixedly connected to the side wall of the plug 11, and the self-locking guide post 74 is located on the lever bracket. 23 in the first installation cavity 231, and the side wall of the first installation cavity 231 limits the self-locking guide post 74. At this time, the second elastic member 72 is in a compressed state as shown in Figure 10; at the same time, there is a gap L between the unlocking guide post 81 and the guide post pressing block 73. It should be noted that the pre-pressure between the side wall of the first installation cavity 231 and the self-locking guide post 74 can be changed by adjusting the compression amount of the second elastic member 72 .

When the plug 11 is gradually pushed out of the charging device, the second elastic member 72 is always in a compressed state as shown in FIG. 10 . It can be understood that during this process, the self-locking guide post 74 is in frictional contact with the side wall of the first installation cavity 231 .

Figure 12 shows a schematic structural diagram of the self-locking step of a charging device provided by an embodiment of the present application. As shown in Figure 12, when the plug 11 is fully extended out of the housing, at this time, the self-locking guide post 74 is opposite to the self-locking guide post hole 71. However, since the unlocking guide post 81 is located at the first position 821a of the slope 821, the self-locking guide post 74 does not extend into the self-locking guide post hole 71. Continuing to push the paddle 30 in the pushing direction, the unlocking guide post 81 moves from the first position 821a of the slope 821 of the paddle unlocking groove 82 to the second position 821b. During the movement of the unlocking guide post 81, the second elastic member 72 gradually After the compression is released, under the action of the elastic force of the second elastic member 72 , the self-locking guide post 74 connected to the unlocking guide post 81 gradually extends into the self-locking guide post hole 71 . At this time, as shown in FIG. 13 , there is no gap between the unlocking guide post 81 and the guide post pressing block 73 .

By arranging the slope 821, the second elastic member 72 can be gradually decompressed to prevent the self-locking guide post 74 from popping out instantly, ensuring that the self-locking guide post 74 enters the self-locking guide post hole 71, and preventing the self-locking guide post 74 from being unstable. The elastic force of the second elastic member causes the injection direction to deviate. At the same time, it can also extend the service life.

It should be noted that along the direction perpendicular to the pushing direction, the distance between the second position 821b of the paddle unlocking groove 82 and the self-locking guide post hole 71 must ensure that the self-locking guide post 74 can extend into the self-locking guide post hole. 71 in.

It should be noted that the position of the self-locking guide post hole 71 is related to the position of the self-locking guide post 74 when the plug 11 moves to the end position.

It should be noted that the length of the self-locking guide post 74 is subject to the condition that the self-locking guide post 74 can extend into the self-locking guide post hole 71 .

In the above embodiment, when the plug 11 reaches the end position, in order to realize the self-locking process, the paddle 30 will continue to be pushed. However, the plug 11 connected to the paddle 30 should no longer move with the movement of the paddle 30 . In order to avoid the problem that the plug 11 moves during the self-locking process, or the plug 11 blocks the movement of the paddle 30 , embodiments of the present application provide a structure of a paddle guide groove 641 .

Figure 14 shows a schematic structural diagram of a charging device provided by an embodiment of the present application. As shown in FIG. 14 , in some embodiments, a width margin should be reserved between the paddle guide groove 641 and the second guide post 642 along the pushing direction.

The paddle guide groove 641 includes a third position 641a and a fourth position 641b. When the plug 11 has just reached the end position, the second guide post 642 is located at the third position 641a of the paddle guide groove 641. When the paddle 30 continues to push along Since the first guide post 622 abuts the guide groove 232, the plug 11 is pushed into place and cannot continue to move forward. The second guide post 642 gradually moves to the fourth position 641b of the paddle guide groove 641. In this way, by ensuring the relative positions of the third position 641a and the fourth position 641b along the pushing direction, the normal movement of the paddle 30 and the non-movement of the plug 11 during the self-locking process can be ensured.

When the charging device completes charging, the plug 11 needs to be retracted into the charging device. To retract the plug 11 into the charging device, the self-locking guide post 74 extending into the self-locking guide post hole 71 must first be returned to the first installation cavity 231 middle.

The structure of the paddle unlocking groove 82 and the process of the self-locking guide post 74 returning to the first installation cavity 231 will be described below with reference to the accompanying drawings.

Figure 15 shows a schematic structural diagram of a charging device provided by an embodiment of the present application. As shown in Figure 15, when the paddle 30 retracts along the retraction direction, the paddle unlocking groove 82 of the paddle bracket 31 cooperates with the slope 821 of the self-locking structure 70 to generate a component force perpendicular to the retreat direction. This component force Pull the self-locking guide post 74 out of the self-locking guide post hole 71 of the pick bracket 31 to unlock the self-locking structure 70 . Specifically, during unlocking, initially, the plug 11 is located at the end position, and the second guide post 642 is located at the fourth position 641b of the paddle guide groove 641. When the paddle 30 continues to move in the retraction direction, along the inclined plane 821, the second The two guide posts 642 move to the third position 641a of the paddle guide groove 641, and the second elastic member 72 is gradually compressed until the self-locking guide post 74 comes out of the self-locking guide post hole 71 of the paddle bracket 31. After the unlocking is completed, the paddle bracket 31 continues to retreat in the retreat direction, which will drive the paddle 61 to rotate, thereby driving the plug 11 to return to the initial position.

During this process, because there is a gap between the second guide post 642 and the paddle guide groove 641, the plug does not actually move back.

It can be seen from the charging device provided in the above embodiment that by moving the paddle assembly, the push-out assembly and the self-locking structure can be controlled simultaneously. When the self-locking structure realizes self-locking, if you continue to push the paddle assembly, the plug will not continue to be pushed out, but the self-locking guide post of the self-locking structure can enter the self-locking guide post hole of the lever bracket. In addition, it can also prevent the plug from shaking back and forth in the pushing direction, thereby improving the accuracy of the product and optimizing the user's experience.

The charging device provided by the embodiment of the present application can realize the push-out process and self-locking process of the plug by pushing out the pick along the push-out direction; by retracting the pick along the retreat direction, it can realize the plug-in process. The unlocking process and the return process make the charging device easy to use.

In the above embodiments, the self-locking structure and the unlocking structure in the charging device are split structures, which occupy a large space. In order to make the charging device more compact, the embodiment of the present application also provides another charging device, in which a guide is used. The cooperation of the groove, the first guide hole and the first guide post can not only push out the plug, but also achieve self-locking and unlocking. In this way, the number of parts of the charging device is small, and the parts occupy a small space, which is conducive to the compactness of the charging device. design. A detailed description will be given below with reference to the accompanying drawings.

Figure 16 shows a schematic structural diagram of a charging device provided by an embodiment of the present application. As shown in Figure 16, in some embodiments, the charging device includes: a housing 20, a plug 11, a lever 61, and a first conversion structure 62; the plug 11 is slidingly connected to the housing 20; the lever 61 and the housing 20 Rotating connection; the lever 61 is connected to the plug 11 through a first conversion structure 62, and the first conversion structure 62 is used to convert the rotational movement of the lever 61 into a linear movement of the plug 11; when the lever 61 rotates relative to the housing 20, The first conversion structure 62 can drive the plug 11 to slide relative to the housing 20 to slide out of the housing 20 or to retreat into the housing 20 .

It can be understood that the plug 11 in the charging device provided by the embodiment of the present application may be a male or a female.

The first conversion structure 62 includes a first guide hole 621 and a first guide post 622; the first guide hole 621 is provided on the lever 61, and the first guide post 622 is provided on the plug 11; the first guide hole 621 is provided along the The radial direction a-a' of the rotation trajectory of the rod 61 extends; the first guide hole 621 is penetrated on the first guide post 622. When the lever 61 rotates, the first guide post 622 can move along the inside of the first guide hole 621. The plug 11 slides in the extending direction of the first guide hole 621 to drive the plug 11 to move linearly.

In this way, the charging device can push out and retreat the plug.

In order to realize the self-locking of the plug 11 after being pushed out and the unlocking of the plug 11 before it retreats into the housing 20, combined with Figure 16 and Figure 17a, the housing 20 is provided with a guide groove 232, and the first guide post 622 passes through Through the guide groove 232, the first guide hole 621 can be entered. The guide groove 232 includes a first hole section 232a and a second hole section 232b; the second hole section 232b is connected with the first hole section 232a, and the first guide post 622 can enter the second hole section 232b from the first hole section 232a. A guide post 622 can also enter the first hole section 232a from the second hole section 232b. The second hole section 232b is located at an end of the first hole section 232a close to the plug 11 . In this way, when the plug 11 is pushed out, the first guide post 622 first moves linearly in the first hole section 232a. When the plug 11 is pushed out into place, the first guide post 622 enters the second hole section from the tail of the first hole section 232a. 232b. Before the plug 11 retreats into the housing 20, the first guide post 622 first moves linearly in the second hole section 232b. When the first guide post 622 enters the first hole section 232a from the tail of the second hole section 232b, , the plug 11 gradually retreats into the housing 20 . It can be understood that the movement trajectory of the first guide post 622 is limited by the guide groove 232, and the first guide post 622 will move along the first hole section 232a and the second The extending direction of the hole section 232b slides.

In some embodiments, the extension direction ee' of the first hole section 232a is consistent with the direction of linear movement of the plug 11 (the ejection direction shown in Figures 16 and 17a), and the extension direction f- of the second hole section 232b f' forms a first included angle α with the direction of linear motion of the plug 11 (the pushing direction shown in Figures 16 and 17a), and the first included angle α is non-zero, for example, it can be 90° or 70°. . That is to say, the first hole section 232a and the second hole section 232b make the guide groove 232 a groove with a bent tail instead of a straight groove.

And, along the direction perpendicular to the linear movement of the plug 11 , the first guide post 622 is slidably connected relative to the plug 11 . In this way, when the first guide post 622 is in the second hole section 232b, the first guide post 622 will move relative to the plug 11 in a direction perpendicular to the linear motion of the plug 11. In order to realize the sliding connection of the first guide post 622 relative to the plug 11, in one implementation, the plug 11 is provided with a slide groove 6222, and a slide block 6221 is provided in the slide groove 6222. The slide block 6221 can be positioned relative to the slide groove 6222. The first guide post 622 slides in a direction perpendicular to the linear movement of the plug 11, and the first guide post 622 is fixed on the slider 6221. In this way, the first guide post 622 can slide relative to the chute 6222 in a direction perpendicular to the linear movement of the plug 11 to achieve the first The guide post 622 and the plug 11 move relative to each other in a direction perpendicular to the linear movement of the plug 11 .

During the process of pushing out the plug 11, the lever 61 rotates in the pushing direction, and the first guide column 622 first moves linearly in the pushing direction in the first hole section 232a. The first guide column 622 and the plug 11 are relatively stationary, and the first guide column 622 is relatively stationary. 622 moves toward the outside of the housing 20 together with the plug 11 . When the plug 11 is pushed out into place, the lever 61 continues to rotate in the pushing direction, the first guide post 622 enters the second hole section 232b from the tail of the first hole section 232a, and the first guide post 622 moves away from the second hole section 232b. When the hole segment 232a moves in the direction, the first guide post 622 and the plug 11 no longer remain relatively stationary, and the first guide post 622 and the plug 11 move relatively in a direction perpendicular to the linear motion of the plug 11. The plug 11 will not continue to slide outward relative to the housing 20, but will remain relatively stationary with the housing 20. That is to say, the self-locking process of the plug 11 after being pushed out is completed.

In the process of retracting the plug 11, the self-locking of the plug 11 must be contacted first. Otherwise, the plug 11 will not move relative to the housing 20 and cannot return to the housing 20. Before the plug 11 retracts into the housing 20 , the lever 61 rotates in the retracting direction (that is, the opposite direction of the pushing direction), and the first guide post 622 first moves in the second hole section 232b toward the end of the second hole section 232b close to the first hole section 232a At this time, the first guide post 622 and the plug 11 move relatively in a direction perpendicular to the linear movement of the plug 11 , and the plug 11 is relatively stationary relative to the housing 20 . Until the first guide post 622 moves to the connection between the first hole section 232a and the second hole section 232b, the lever 61 continues to rotate in the retreat direction (that is, the opposite direction of the pushing direction), and the first guide post 622 can move from the first hole section 232a to the second hole section 232b. The tail portions of the two hole sections 232b enter the first hole section 232a, thereby realizing the retraction of the plug 11. That is to say, the unlocking process of the plug 11 before retracting into the housing 20 is completed. After completing the unlocking process, the lever 61 continues to rotate in the retraction direction (that is, the opposite direction of the push-out direction), and the first guide post 622 linearly moves in the retraction direction in the first hole section 232a. Driven by the first guide post 622 downward, the plug 11 gradually retreats into the housing 20 .

In one implementation, in order to make it easier for the first guide post 622 to enter from the first hole section 232a into the second hole section 232b, or to make it easier for the first guide post 622 to enter from the second hole section 232b. In the first hole section 232a, a rounded corner R is provided at the connection between the first hole section 232a and the second hole section 232b.

As mentioned above, the guide groove 232 is a groove with a bent tail, and the movement trajectory of the first guide post 622 is restricted by the guide groove 232, thereby realizing self-locking of the plug 11 after being pushed out, and unlocking of the plug 11 before retreating.

After completing the self-locking, when inserting the plug 11 into the power supply, the power supply may cause the plug 11 to move in the retracting direction. The plug 11 will transmit the force to the lever 61 through the first conversion structure 62. The lever 61 may be driven by the force to withdraw from the second hole section 232b, causing the plug 11 to The action of plugging plug 11 into the power supply failed. In order to improve the reliability of self-locking and prevent the first guide post 622 from withdrawing from the second hole section 232b, the charging device provided by the embodiment of the present application also includes a third elastic member 65.

The third elastic member 65 has one end fixedly connected to the lever 61 and the other end fixedly connected to the housing 20 . The initial state of the third elastic member 65 may be a compressed state. When the plug 11 slides toward the outside of the housing 20, the lever 61 rotates along the first direction (i.e., the pushing direction). When the plug 11 retreats toward the housing 20, the lever 61 rotates along the second direction opposite to the first direction (i.e., the pushing direction). The opposite direction of the push-out direction) rotation.

When the lever 61 rotates in the first direction, the third elastic member 65 is continuously compressed. When the rotation of the third elastic member 65 exceeds the zero point, the spring force of the third elastic member 65 becomes the driving force, and the third elastic member 65 is in a compressed state. The third elastic member 65 is used to provide elastic force to the lever 61 to drive the first guide post 622 into the second hole section 232b and enter the self-locking state. And the lever 61 is under the elastic force provided by the third elastic member 65. Even if the lever 61 is acted upon by the plug 11 in the retraction direction, the elastic force provided by the third elastic member 65 is divided along the first direction. The force and the force of the plug 11 in the retracting direction are in opposite directions, and the self-locking state can still be maintained. It can be understood that during the rotation of the lever 61, before the spring force of the third elastic member 65 becomes the driving force, if the lever 61 is stopped to be pushed, the lever 61 may automatically reset, causing the plug 11 to be unable to continue to extend. out of the housing 20. The lever 61 should be pushed into place to ensure that the plug 11 extends out of the housing 20 .

When the lever 61 rotates in the second direction, the third elastic member 65 is continuously compressed. When the rotation of the third elastic member 65 exceeds the zero point, the spring force of the third elastic member 65 becomes the driving force, and the third elastic member 65 is in a compressed state. The third elastic member 65 is used to provide elastic force to the lever 61. When the plug 11 is retracted into place, the component force along the first direction of the elastic force provided by the third elastic member 65 to the lever 61 is opposite to the first direction. Automatic ejection of plug 11 can therefore be prevented.

There are many ways to fix the connection between the third elastic member 65 and the lever 61 , for example, it can be glued or connected through a latch. In one implementation, the connection point between the third elastic member 65 and the lever 61 is provided on the side of the lever 61 close to the plug 11. In order to avoid the shell between the third elastic member 65, the lever 61 and the plug 11 20 interfere with each other. In some embodiments, the housing 20 is provided with an annular groove 23b1, and the extending direction of the annular groove 23b1 is consistent with the circumferential direction in which the lever 61 rotates.

During the self-locking process after the plug 11 is pushed into place, the first guide post 622 needs to enter the second hole section 232b from the connection between the first hole section 232a and the second hole section 232b. Furthermore, during the unlocking process before the plug 11 is retracted into the housing 20, the first guide post 622 needs to enter the first hole section 232a from the connection between the first hole section 232a and the second hole section 232b. During these two processes, the movement direction of the first guide post 622 changes, and the first guide post 622 needs to slide relative to the plug 11 . By providing the third elastic member 65, when the spring force of the third elastic member 65 becomes the driving force, additional force can be provided to the lever 61 to realize the positioning of the first guide post 622 between the first hole section 232a and the second hole. Path transformation between segments 232b.

In order to promote the rotation of the lever 61, in some embodiments, the charging device further includes a paddle 30. The structure of the paddle 30 and the connection relationship between the paddle 30 and the lever 61 can be referred to the previous embodiments, and will not be described again here.

In order to achieve simple installation of the charging device, as shown in FIG. 16 , in one implementation, the housing 20 includes a lever bracket 23 . The lever bracket 23 includes a first bracket 23a and a second bracket 23b. The first bracket 23a and the second bracket 23b are fixedly connected, and the second bracket 23b is located between the first bracket 23a and the paddle 30. The plug 11 is disposed in the first bracket 23a and can slide relative to the first bracket 23a. The guide groove 232 is provided on the second bracket 23b, the lever 61 is rotationally connected to the second bracket 23b, and the lever 61 is disposed toward the side of the second bracket 23b away from the first bracket 23a. The first guide post 622 is opposite to the first guide hole 621 , and the first guide post 622 is inserted into the first guide hole 621 . At this time, if the paddle 30 is pushed, the paddle 30 drives the lever 61 to rotate, and the lever 61 drives the plug 11 to move linearly.

In order to realize the self-locking of the plug after being pushed out and the unlocking of the plug before retreating into the housing 20, in addition to providing a guide groove with a first hole section and a second hole section on the housing 20, a third hole section can also be provided. The first guide hole of the three-hole section and the fourth hole section. The first guide hole including the third hole section and the fourth hole section will be described in detail below with reference to Figure 17b of the accompanying drawing.

As shown in Figure 17b, in other embodiments, the first conversion structure 62 includes a first guide hole 621 and a first guide post 622; the first guide hole 621 is provided on the lever 61, and the first guide post 622 is provided on On the plug 11; the first guide hole 621 includes a third hole section 621a and a fourth hole section 621b; the third hole section 621a extends along the radial direction o-o' of the rotational movement track of the lever 61, and the fourth hole section 621b The extension direction and the extension direction of the third hole segment 621a form a third included angle θ, and the third included angle θ is non-zero (for example, it can be 90° or 100°). The fourth hole segment 621b and the third hole The segments 621a are connected, and the fourth hole segment 621b is located at the third end 6101 of the third hole segment 621a. The third hole section 621a includes a third end 6101 and a fourth end 6102. Compared with the fourth end 6102, the third end 6101 is farther from the rotation axis of the lever 61.

In this way, when pushing the plug 11 out of the housing 20 , push the lever 61 along the pushing direction (consistent with the first direction), the lever 61 rotates along the first direction, and the first guide post 622 is in the first guide hole 621 The middle movement along the extension direction of the third hole section 621a drives the plug 11 to gradually slide out of the housing 20. When the plug 11 is pushed out into place, continue to push the lever 61 in the pushing direction, and the first guide post 622 enters the fourth hole section 621b. , the first guide post 622 is restricted by the side wall surface of the fourth hole section 621b and cannot drive the plug 11 to continue sliding. At this time, if the plug 11 is pushed in the opposite direction to the first direction, the first guide post 622 on the plug 11 is restricted by the side wall surface of the fourth hole section 621b and cannot drive the lever 61 to rotate in the opposite direction to the first direction. Thus realizing the self-locking process. If it is necessary to move the plug 11 slid out of the housing 20 back into the housing 20 , push the lever 61 in the opposite direction to the first direction, and the first guide post 622 gradually withdraws from the fourth hole section 621b and enters. In the third hole section 621a, at this time, the unlocking process is completed. Continuing to push the lever 61 in the opposite direction to the first direction, the plug 11 gradually retreats into the housing 20 .

In order to enable the first guide post 622 to withdraw smoothly from the fourth hole section 621b, in some embodiments, the charging device further includes: a fourth elastic member 66; one end of the fourth elastic member 66 is fixedly connected to the lever 61, The other end is fixedly connected to the housing 20 . The structure and function of the fourth elastic member 66 can be referred to the first elastic member 63 in the previous embodiment (as shown in FIG. 5 ), and will not be described again here. In some application scenarios, the charging device is used to charge Bluetooth headsets, such as a TWS charging box. The charging device is provided with a storage slot for placing Bluetooth headsets (see Figure 3). For convenience of description, the storage slot for placing Bluetooth headsets is referred to as Headphone compartment. In order to realize the opening and closing of the earphone compartment relative to the casing (or the pop-up and push-back actions of the earphone compartment relative to the casing), the charging device provided by the embodiment of the present application also includes a fifth elastic member and a snap-in structure, which are combined below The accompanying drawings illustrate a charging device with a headphone compartment opening and closing function. Figure 18a shows a schematic structural diagram of another charging device provided by an embodiment of the present application. As shown in Figure 18a, the charging device includes a housing 20, an earphone compartment 50a, a fifth elastic member 90a, and a clamping structure 90b. When the earphone compartment 50a is clamped with the housing 20 through the clamping structure 90b, the earphone compartment 50a and the shell 20 are connected together. Under the force of the clamping, the earphone compartment 50a can overcome the elastic force of the fifth elastic member 90a, and the earphone The compartment 50a is stationary relative to the casing 20 and the earphone compartment 50a is located in the casing 20; when the clamping structure 90b disconnects the earphone compartment 50a and the casing 20, the earphone compartment 50a The machine compartment 50a slides relative to the housing 20 under the elastic force of the fifth elastic member 90a.

The earphone compartment 50a is slidably connected to the first bracket 23a. For example, as shown in Figure 18a, a snap-in plate 234a can be provided on the earphone compartment 50a, and a snap-in slot 234b can be arranged on the first bracket 23a. The snap-in plate 234a is opposite to the snap-in slot 234b, and the snap-in plate 234a can extend in. In the locking groove 234b, in this way, the locking plate 234a and the locking groove 234b can slide relative to each other, so that the earphone compartment 50a and the first bracket 23a can be slidably connected. For example, two latching plates 234a may be provided, and the two latching plates 234a may be provided on opposite sides of the earphone compartment 50a along a direction perpendicular to the ejection direction of the earphone compartment. There may be two latching grooves 234b, and the two latching grooves 234b are provided on opposite sides of the first bracket 23a perpendicular to the pop-up direction of the earphone compartment. In this way, the first bracket 23a is located between the two latching plates 234a. And the two clamping plates 234a are respectively clamped in the corresponding clamping grooves 234b. The clamping plates 234a can relatively slide relative to the clamping grooves 234b in a direction parallel to the ejection direction of the earphone compartment, thereby realizing the earphone compartment 50a and the first bracket 23a. Sliding connection possible.

The earphone compartment 50a is connected to the housing 20 through the fifth elastic member 90a. The initial state of the fifth elastic member 90a may be a compressed state. The fifth elastic member 90a is used to apply an elastic force to the earphone compartment 50a. The direction of the elastic force is consistent with the pop-up direction of the earphone compartment 50a, so that the earphone compartment 50a can be positioned relative to the earphone compartment 50a. The housing 20 slides and can be ejected out of the housing 20 . That is to say, the fifth elastic member 90a can provide a driving force to the earphone compartment 50a, and the driving force causes the earphone compartment 50a to slide relative to the housing 20. In one implementation, the fifth elastic member 90a can provide a driving force to the latch plate 234a, and the driving force enables the latch plate 234a to slide relative to the latch groove 234b. One fifth elastic member 90a can be provided as shown in Figure 18a, or two as shown in Figure 19. There can also be multiple fifth elastic members 90a. The number of fifth elastic members 90a is not determined in this application. limited.

There are many ways to connect the fifth elastic member 90a to the earphone compartment 50a and the housing 20. For example, it can be glued or connected through pins. In one implementation, as shown in Figure 18a, a first hook 90a1 is provided at an end of the fifth elastic member 90a away from the earphone compartment 50a, and a first hook groove 235 is provided on the housing 20. The first hook 90a1 can be hung on the first hook groove 235 of the housing 20 . In one implementation, the initial state of the fifth elastic member 90a is a compressed state, the earphone compartment 50a may be provided with a second hook groove, and an end of the fifth elastic member 90a close to the earphone compartment 50a may be provided with a second hook. The hook can be hung on the second hook groove of the earphone compartment 50a to realize the connection between the fifth elastic member 90a and the earphone compartment 50a. When the casing 20 and the earphone compartment 50a are released from the snap-locking relationship, the fifth elastic member 90a in the compressed state will exert force on the earphone compartment 50a, and the earphone compartment 50a will pop out of the casing 20 under the action of this force. .

It can be understood that in some embodiments, the end of the fifth elastic member 90a away from the earphone compartment 50a is connected to the housing 20, and the end of the fifth elastic member 90a close to the earphone compartment 50a may only be in contact with the earphone compartment 50a, and It is not fixedly connected with the earphone compartment 50a. When the casing 20 and the earphone compartment 50a are released from the snap-locking relationship, the fifth elastic member 90a in the compressed state will exert force on the earphone compartment 50a, and the earphone compartment 50a will pop out of the casing 20 under the action of this force. . However, if the earphone compartment 50a is pushed back into the housing 20, since there is no connection between the fifth elastic member 90a and the earphone compartment 50a, the position of the fifth elastic member 90a may shift, which is not conducive to repeated opening of the earphone compartment 50a. combine. Therefore, at the position where the fifth elastic member 90a contacts the earphone compartment 50a, an accommodating groove can be provided at the corresponding position of the earphone compartment 50a, and the end of the fifth elastic member 90a close to the earphone compartment 50a can extend into the accommodating groove, even if the earphone The compartment 50a pops out of the housing 20, and the end of the fifth elastic member 90a close to the earphone compartment 50a is still located in the receiving groove. In this way, the position of the fifth elastic member 90a will not shift, and the earphone compartment 50a can be opened and closed repeatedly. .

As shown in Figure 18b, the charging device provided by the embodiment of the present application can use a terminal device (such as a mobile phone 400) to reverse charge the TWS charging box by realizing the push-out action, the retracting action, and the self-locking and unlocking functions of the plug, thereby improving User charging convenience and unlimited battery life experience.

Two possible implementation methods of the snap-in structure are given below, and the opening and closing methods of the earphone compartment in the charging device are explained in combination with specific implementation methods.

FIG. 19 is a schematic structural diagram of an implementation manner of the locking structure of the earphone compartment in the charging device shown in FIG. 18a. As shown in FIG. 19 , in one implementation, the clamping structure 90b includes a rotating rod 91 and a clamping groove 92 . It can be understood that, in order to clearly show the shape of the card slot 92, compared with the earphone compartment 50a shown in FIG. 18a, the earphone compartment 50a shown in FIG. 19 is vertically flipped 180°.

The card slot 92 is provided on the earphone compartment 50a. Exemplarily, the card slot 92 includes a protruding part 921 and a concave groove 922. The protruding part 921 is provided on the earphone compartment 50a. A concave groove 922 is formed in the protruding part 921, and the protruding part 921 is provided with a hole for inserting. Notch 921a.

The rotating lever 91 is provided on the housing 20 . The rotating rod 91 is rotatably connected to the housing 20 . An extension portion 912 is provided at one end of the rotating rod 91 close to the slot 92; the extension direction g-g' of the extension portion 912 and the ejection direction of the earphone compartment 50a form a second included angle β; the angle β of the second included angle is non-zero. (For example, it can be 90° or 100°). In other words, one end of the rotating rod 91 close to the slot 92 is provided with a structure for hooking the earphone compartment 50a. Specifically, the protruding portion 912 can enter the concave groove 922 through the notch 921a. The shape of the extension portion 912 is not limited in this application. The extension portion 912 can extend into the card slot 92 to realize the card connection between the earphone compartment 50a and the casing 20. The protruding portion 912 can withdraw from the card slot 92 to release the card connection between the earphone compartment 50 a and the housing 20 . The rotation of the rotating rod 91 can drive the extension portion 912 to extend into or out of the slot 92. In this way, as long as the rotating rod 91 is driven to rotate, the engagement or release between the earphone compartment 50a and the housing 20 can be controlled. For example, when the rotating lever 91 rotates along the third direction, the third direction is opposite to the extension direction of the extending portion 912, and the extending portion 912 exits the slot 92, releasing the engagement between the earphone compartment 50a and the housing 20; the rotating lever When 91 rotates in the fourth direction (opposite to the third direction), the extension portion 912 is used to extend into the card slot 92 to achieve the card connection between the earphone compartment 50 a and the housing 20 . The rotating rod 91 may be a straight rod or a bent rod as shown in FIG. 19 . The shape of the rotating rod 91 is not limited in this application. Exemplarily, the rotating rod 91 includes a rotating shaft 913. The rotating shaft 913 is located in the middle of the rotating rod 91. An extension portion 912 is provided at one end of the rotating rod 91 close to the slot 92. The rotating rod 91 is located between the extending portion 912 and the rotating axis. The part between 913 is the first sub-rod 91a, and the part between the end of the rotating rod 91 away from the headphone compartment and the rotating shaft 913 is the second sub-rod 91b. The first sub-rod 91a is used to drive the extension part 912 to move. The second sub-rod 91b is used to drive the first sub-rod 91a to rotate.

In the initial state, the earphone compartment 50a is in a closed state, the earphone compartment 50a is completely located in the housing 20, and the extension part 912 extends into the card slot 92; when the rotating rod 91 is pushed in the third direction, the extension part 912 gradually moves from the card slot 91 to the card slot 92. After the extension part 912 is completely pushed out of the slot 92, the earphone compartment 50a and the housing 20 are released from the locking structure 90b, and the earphone compartment 50a is released under the action of the fifth elastic member 90a. Ejected relative to the housing 20 . In this way, the action of opening the earphone compartment 50a is completed. When the earphone compartment 50a returns to the housing 20, by pressing the side of the earphone compartment 50a away from the housing 20, the slot 92 gradually approaches the rotating rod 91, and the rotating rod 91 is pushed to rotate in the fourth direction, and the extending portion 912 gradually Close to the slot 92, when the headphone compartment 50a is pushed back into place, continue to push the rotating rod 91 to rotate in the fourth direction, and the extension 912 gradually enters the slot 92, thereby realizing the locking connection between the earphone compartment 50a and the casing 20.

In order to push the rotating rod 91 to rotate in the third direction, in one implementation, the charging device further includes a pushing piece 97 , the pushing piece 97 and the rotating rod 91 are disposed on the same side of the housing 20 , and the pushing piece 97 and the rotating rod 91 Set in sequence along the pop-up direction. Specifically, the pushing piece 97 and the rotating rod 91 can be provided on the side of the second bracket 23b away from the first bracket 23a. A lever 61 is provided between the pushing piece 97 and the second bracket 23b. The pushing piece 97 is provided with a pushing groove 971 close to the rotating rod 91. The pushing groove 971 can be a U-shaped groove as shown in Figure 18a. When the pushing piece 97 is pushed in the ejection direction, the pushing groove 971 can contact the rotating rod 91. Thereby, the rotating rod 91 is pushed to rotate in the third direction.

In one implementation manner, one end of the second sub-rod 91b close to the pushing piece 97 is arc-shaped as shown in Figure 18a. This makes it easier for the pushing piece 97 to push the second sub-rod 91b.

It can be understood that since the lever 61 is disposed between the pushing piece 97 and the first bracket 23 a, in order to enable the pushing piece 97 to push the rotating rod 91 to rotate, the end of the rotating rod 91 close to the pushing piece 97 extends along a direction perpendicular to the pushing piece 97 The height in the direction is greater than the height of the lever 61 in the direction perpendicular to the pushing piece 97 .

To open and close the earphone compartment 50a, it is necessary to provide power to push the rotating rod 91 to rotate in the fourth direction. There are many power sources. For example, the rotating lever 91 can be manually pushed. However, manual pushing is not easy to operate, and the user's operating experience is not good. At the same time, the rotating rod 91 needs to be exposed to the outside of the charging device, which is not conducive to the appearance of the charging device. If the action of pushing back the earphone compartment 50a can be used to realize the linkage of the two actions of "pushing back the earphone compartment 50a" and "pushing the rotating rod 91 to rotate in the fourth direction", the operation of pushing back the earphone compartment 50a can be greatly improved. Simplicity. In one implementation, the charging device further includes a sixth elastic member 93; one end of the sixth elastic member 93 is connected to the housing 20, and the other end is connected to the rotating rod 91. For example, the initial state of the sixth elastic member 93 may be in a compressed state. When the earphone compartment 50a is ejected out of the housing 20, the rotating rod 91 rotates in the third direction, and the sixth elastic member 93 continues to be compressed. When the sixth elastic member 93 is in the critical state, the spring force of the sixth elastic member 93 becomes a driving force. When the earphone compartment 50a and the housing 20 are released from the engagement, the rotating rod 91 will move along the first driving force under the action of the driving force. When rotation occurs in four directions, the sixth elastic member 93 can return the rotating rod 91 to the initial state. When the earphone compartment 50a is pressed back into the housing 20, the earphone compartment 50a can apply force to the rotating rod 91. The direction of the force is opposite to the ejection direction. The application point of the force can be located at the rotating rod 91 close to the earphone compartment 50a. At one end, the force can directly act on the protruding portion 912. The earphone compartment 50a first causes the rotating rod 91 to rotate a certain angle along the third direction. The sixth elastic member 93 continues to be compressed. When the critical state of the sixth elastic member 93 is exceeded, At this time, the spring force of the sixth elastic member 93 becomes a driving force. Under the action of the driving force, the rotating rod 91 will rotate in the fourth direction, and the extension portion 912 gradually extends into the slot 92 to realize the headphone compartment. 50a and the housing 20 are snap-connected.

In order to allow the headphone compartment 50a to be pushed back into the housing 20, the rotating lever 91 can rotate a certain angle along the third direction. On the one hand, this can be achieved by setting the initial position of the rotating lever 91, for example, The initial position forms a certain angle with the pop-up direction of the earphone compartment 50a. In other words, the rotating rod 91 is inclined relative to the ejection direction of the earphone compartment 50a. On the other hand, as shown in FIG. 19 , a chamfer T1 can also be provided on the side of the extension portion 912 close to the earphone compartment 50 a , and a chamfer T2 can be provided on the slot 92 at a position opposite to the chamfer T1 . At this time, the initial position of the rotating lever 91 may be parallel to the ejection direction of the earphone compartment 50a.

After the earphone compartment 50a and the housing 20 are released from the snapping relationship, the rotating rod 91 will rotate in the fourth direction, that is, rotate, under the action of the driving force of the sixth elastic member 93.
