In order to make the technical solution of the present invention more clearly understood by those skilled in the art to which the present invention pertains, the following detailed description of the technical solution of the present invention is provided by way of specific embodiments with reference to the accompanying drawings.

Fig. 1 and 2 schematically show application scenarios according to embodiments of the present disclosure. Specifically, fig. 1 schematically illustrates a schematic view of a second portion of an electronic device with an aperture according to an embodiment of the disclosure. Fig. 2 schematically shows a schematic view of a second part of an electronic device without an opening according to an embodiment of the disclosure.

As shown in fig. 1 and 2, the electronic device 10 includes a first portion 100 and a second portion 200. According to the embodiment of the present disclosure, the electronic device 10 may be, for example, a notebook computer or a tablet computer with an external device.

When the electronic device 10 is a notebook computer, the first portion 100 may be, for example, a display end of the notebook computer, and the second portion 200 may be, for example, a system end of the notebook computer. Specifically, the first portion 100 may be provided with a display screen, wherein the display screen may be a display screen with a touch function or a display screen without a touch function. The second portion 200 may be provided with a keyboard, and may also be provided with a fingerprint acquisition device, a touch pad, etc. According to the embodiment of the present disclosure, when the notebook computer 10 is in the closed state, there are, in order from top to bottom, a-cover (e.g., the housing surface of the first portion 100), B-cover (e.g., the display screen surface of the first portion 100), C-cover (e.g., the keyboard surface of the second portion 200), and D-cover (e.g., the housing surface of the second portion 200).

According to the embodiment of the present disclosure, the first portion 100 and the second portion 200 of the electronic device may be connected by a hinge such that the first portion 100 can rotate relative to the second portion 200. For example, a sunken hinge may be used to connect the first and

second portions

100 and 200 of the electronic device.

Specifically, as shown in fig. 1, when the first portion 100 and the second portion 200 of the electronic device are connected by using the sunken hinge, when the electronic device is in the open state, the C-cover of the electronic device may have an opening 300 at the hinge connection, which results in the C-cover visually lacking the overall aesthetic property and affecting the visual effect.

The embodiment of the disclosure provides a mechanical structure, which can shield the opening 300 in the opening process of the electronic device, so that the C-cover has a complete appearance, thereby improving the visual effect and improving the user experience. For example, as shown in fig. 2, when the first part 100 and the second part 200 of the electronic device 10 are in the open state, the mechanical structure 400 can block the opening 300 at the C-cover to make the C-cover look a complete plane, so that the electronic device is more novel and beautiful in appearance.

In connection with the application scenarios of fig. 1-2, the mechanical structure according to an exemplary embodiment of the present disclosure is described with reference to fig. 3A-3D and fig. 4A-4D. It should be noted that the above application scenarios are merely illustrated for the convenience of understanding the spirit and principles of the present invention, and the embodiments of the present invention are not limited in this respect. Rather, embodiments of the present invention may be applied to any scenario where applicable.

3A-3D schematically illustrate a schematic of a mechanical structure 400 according to an embodiment of the present disclosure; and fig. 4A-4D schematically illustrate schematic views of a transmission structure 420 according to an embodiment of the disclosure.

The mechanical structure 400 may be disposed, for example, inside one of the first portion and the second portion.

For example, as shown in fig. 3A, the mechanical mechanism 400 of an embodiment of the present disclosure may be disposed in the second portion 200 of the electronic device, for example. For example, it may be located near the junction of the shafts to facilitate the mechanical structure 400 to block the opening 300.

According to an embodiment of the present disclosure, the mechanical structure 400 may be hidden in the second portion 200 when the included angle between the first portion 100 and the second portion 200 of the electronic device is within a first range (e.g., 0 degrees to 60 degrees). When the angle between the first portion 100 and the second portion 200 of the electronic device is within two ranges (e.g., 60 degrees to 180 degrees), a part of the mechanical structure 400 may block the opening 300.

Specifically, as shown in fig. 3B, the mechanical structure 400 may include a rotating shaft 410, a transmission structure 420, a baffle 430, a first bracket 440, and a second bracket 450. Wherein the first bracket 440 is fixed in the first portion 100 and the second bracket 450 is fixed in the second portion 200.

The rotation shaft 410 is connected to one of the first and

second parts

100 and 200 and can rotate relative to the other. In the disclosed embodiment, the shaft 410 may be coupled to the first portion 100 and may be capable of rotating relative to the second portion 200.

According to the embodiment of the present disclosure, the rotation shaft 410 may have a cylindrical structure that is symmetrical along the axial direction, for example, a portion of the rotation shaft 410 may have a cylindrical shape so that the partial structure may rotate with respect to the rotation shaft, or a portion of the rotation shaft 410 may have a prismatic shape so that the partial structure is fixed so that the partial structure cannot rotate with respect to the rotation shaft 410. It is to be understood that the present disclosure is not limited to the shape of the shaft 410, as long as it is ensured that each fitting connected to the shaft 410 can perform its function.

Specifically, the shaft 410 may be coupled to a first bracket 440 to couple the shaft 410 to the first portion. It can be understood that the rotating shaft 410 may also be engaged with or hinged to the first bracket 440, or the first bracket 440 may also be sleeved on a portion of the rotating shaft 410, and the disclosure does not limit the connection manner between the rotating shaft 410 and the first bracket 440, as long as the rotating shaft 410 and the first bracket 440 do not rotate relatively. According to the embodiment of the present disclosure, the hinge 410 is connected to the first portion 100 of the electronic device through the first bracket 440, and when the first portion 100 rotates relative to the second portion 200, the first bracket 440 can drive the hinge 410 to rotate relative to the second portion 200. One part of the second bracket 450 is fixed to a second part of the electronic device, and the other part is sleeved on the rotating shaft 410, so that the second bracket 450 and the rotating shaft 410 can rotate relatively.

The transmission structure 420 is connected with the rotating shaft 410. The rotating shaft 410 may provide power for the transmission structure 420, for example, that is, the rotating shaft 410 may drive the transmission structure 420 to operate.

In the embodiment of the disclosure, since the second bracket 450 is fixed to the second portion of the electronic device, the transmission structure 420 may be connected to the second bracket 450 to connect the transmission structure 420 and the second portion 200, for example, the transmission structure 420 may be fixed to the second bracket 450 (for example, may be implemented by a process such as integral molding).

Specifically, the transmission structure 420 may be disposed inside the second portion, for example, when the electronic device is a notebook computer, the inside of the second portion may be, for example, the inside of a base with a keyboard, for example, a space between the C-cover and the D-cover.

According to the embodiment of the present disclosure, the transmission structure 420 may be one or any combination of a link structure, a gear structure, or a transmission chain structure, for example. The transmission structure 420 may be, for example, one transmission structure or a combination of a plurality of transmission structures, and the present disclosure does not limit the type, number and combination of the transmission structures.

For example, the transmission structure 420 in embodiments of the present disclosure may refer to the transmission structure shown in fig. 4A-4D. According to the embodiment of the present disclosure, the transmission structure 420 includes a driving gear 421, a driven gear 422, and a transmission chain 423. It is understood that the transmission structures shown in fig. 4A-4D are only exemplary embodiments, and the present disclosure does not limit the specific structure and operation of the transmission structure 420, which can be set by one skilled in the art according to practical situations.

Specifically, the driving gear 421 is connected to the rotating shaft 410. According to the embodiment of the present disclosure, the driving gear 421 may be stably connected to the rotating shaft, that is, the driving gear 421 and the rotating shaft 410 do not move relatively, so that the rotating shaft 410 drives the driving gear 421 to rotate.

For example, as shown in fig. 4A, the center of the driving gear 421 may have a through hole for being sleeved on the rotating shaft 410. For example, the driving gear may be a cylindrical hole sleeved on the cylindrical rotating shaft to form an interference fit, or may also be a prismatic hole sleeved on the corresponding prismatic rotating shaft, so that the driving gear cannot rotate relative to the rotating shaft 410. It should be understood that the above connection manner is only an exemplary illustration, and the disclosure does not limit the connection manner of the driving gear 421 and the rotating shaft 410, for example, the driving gear 421 may also be connected with the rotating shaft 410 by a process such as integral molding.

The driven gear 422 is connected to the driving gear 421. The driving gear 421 can drive the driven gear 422 to work, for example, the driving gear 421 drives the driven gear 422 to rotate when rotating. According to the embodiment of the present disclosure, the driving gear 421 and the driven gear 422 may be connected by a gear tooth contact engagement, or may be connected by a transmission belt, for example.

For example, as shown in fig. 4A, the driving gear 421 and the driven gear 422 can be connected by a transmission belt to achieve a transmission function, that is, the transmission belt can be connected to, for example, a central shaft portion of the driving gear 421 and a central shaft portion of the driven gear 422, and when the driving gear 421 generates a rotational motion, the transmission belt is driven to move, and then, the transmission belt drives the driven gear 422 to generate a rotational motion, so that the driving gear 421 and the driven gear 422 can be coordinated with each other. The drive belt may also be a chain or the like in accordance with embodiments of the present disclosure. It should be understood that the above connection manner is only an exemplary illustration, and the disclosure does not limit the connection manner of the driving gear 421 and the driven gear 422, as long as the driving gear can drive the driven gear to work.

The drive chain 423 is connected to the driven gear 422. The transmission chain 423 may be a rack, for example. According to the embodiment of the present disclosure, the transmission chain 423 may include, for example, teeth that match with the teeth of the driven gear 422, so that the driven gear 422 can drive the transmission chain 423.

For example, as shown in fig. 4A, the transmission chain 423 and the driven gear 422 are in meshing contact with each other through the teeth, and when the driven gear 422 rotates, the teeth of the driven gear drive the teeth of the chain to move, so that the driven gear 422 drives the transmission chain 423 to move. The baffle 430 is coupled to the transmission structure 420. According to the embodiment of the present disclosure, the blocking plate 430 may be connected to the transmission chain 423, for example, the blocking plate 430 may be disposed on the transmission chain 423 of the transmission structure 420, so that the transmission chain 423 can carry the blocking plate 430 to move when the transmission structure 420 rotates. It can be understood that the embodiment of the present disclosure does not limit the connection manner of the baffle and the transmission structure, as long as the transmission structure can drive the baffle 430 to move when rotating.

In the disclosed embodiment, the baffle 430 may include a protrusion, which may be sized to correspond to the size of the opening 300, and may cooperate to block the opening.

According to the embodiment of the present disclosure, the baffle 430 may be fixedly connected to the transmission structure 420, or may be connected to the transmission structure through an elastic component. For example, the blocking plate 430 may be connected to the driving chain 423 of the driving structure through an elastic member, and when the protruding portion of the blocking plate 430 blocks the opening 300, but the first portion of the electronic device is still open relative to the second portion, the elastic member may counteract the force generated by the continuous movement of the driving chain 423, so that the protruding portion of the blocking plate 430 is still located at the opening 300 and does not move along with the movement of the driving chain 423.

Specifically, in the embodiment of the present disclosure, during the process that the first portion 100 and the second portion 200 are opened relative to each other, the rotating shaft 410 drives the transmission structure 420, the transmission structure 420 drives the baffle 430 to move from the position hidden in the second portion 200 to the position capable of blocking the opening, during the process that the first portion 100 and the second portion 200 are closed relative to each other, the rotating shaft 410 drives the transmission structure 420, and the transmission structure 420 drives the baffle 430 to move from the position blocking the opening to the position hidden in the second portion 200.

For example, when the transmission structure 420 is the structure shown in fig. 3A to 3D, during the process of opening the first portion 100 relative to the second portion 200, the rotating shaft 410 rotates relative to the second portion 200 and drives the driving gear 421 to rotate, the driving gear 421 drives the driven gear 422 to rotate, the driven gear 422 drives the transmission chain 423 to move, and further, the transmission chain 423 drives the baffle 430 to move from the position hidden in the second portion 200 to the position blocking the opening.

In the process that the first portion 100 is closed relative to the second portion 200, the rotating shaft 410 rotates relative to the second portion 200 and drives the driving gear 421 to rotate, the driving gear 421 drives the driven gear 422 to rotate, the driven gear 422 drives the transmission chain 423 to move, and further, the transmission chain 423 drives the baffle 430 to move from the position of covering the opening to the position of being hidden in the second portion 200.

When the angle between the first portion 100 and the second portion 200 satisfies a first threshold, the baffle 430 is hidden in the second portion.

In the embodiment of the present disclosure, the first threshold may be, for example, 0 degree to 60 degrees, when the first portion 100 of the electronic device is opened with respect to the second portion 200, for example, during the opening from 0 degree to 60 degrees, the rotating shaft 410 rotates with respect to the second portion 200 and drives the driving gear 421 to rotate, the driving gear 421 drives the driven gear 422 to rotate, the driven gear 422 drives the transmission chain 423 to move, and further, the transmission chain 423 drives the baffle 430 to move from the position hidden in the second portion 200 to the position covering the opening 300.

When the angle between the first portion 100 and the second portion 200 satisfies a second threshold, the baffle 430 is hidden in the second portion. In the embodiment of the present disclosure, the second threshold may be, for example, 60 degrees to 180 degrees, when the first portion 100 of the electronic device is opened relative to the second portion 200, for example, during the opening from 60 degrees to 180 degrees, the rotating shaft 410 rotates relative to the second portion 200 and drives the driving gear 421 to rotate, the driving gear 421 drives the driven gear 422 to rotate, the driven gear 422 drives the transmission chain 423 to move, further, the transmission chain 423 drives the blocking plate 430 to move from the position hidden in the second portion 200 to the position blocking the opening, after the blocking plate 430 completely blocks the opening, the blocking plate does not move with the increase of the opening angle, for example, when the blocking plate 430 moves slowly to block the opening from 60 degrees to 70 degrees, the blocking plate completely blocks the opening when the opening reaches 70 degrees, and at this time, during the opening from 70 degrees to 180 degrees, the blocking plate 430 does not move any more.

Specifically, when the electronic device is opened to 70 degrees, the aperture is completely blocked, and the shutter 430 is no longer moved during the opening process from 70 degrees to 180 degrees.

For example, when the electronic device is opened from 70 degrees to 180 degrees, the baffle 430 may abut against an edge portion of the second portion of the electronic device, and at this time, the baffle is connected to the transmission structure 420 through an elastic member, and in case that the transmission structure 420 continues to move, the elastic member may be used to counteract a force generated by the transmission structure, so that the baffle 430 may be fixed at the opening 300. For another example, as shown in fig. 4C, a part of the chain teeth of the transmission chain 423 that are engaged with the driven gear 422 may be removed, so that the driven gear 422 drives the transmission chain 423 to perform an engaging motion during the process of driving the transmission chain 423, for example, when the electronic device is opened from 0 degree to 70 degrees, the baffle 430 slowly moves to block the opening, and completely blocks the opening when the electronic device reaches 70 degrees; when the electronic device is opened from 70 degrees to 180 degrees, the driven gear 422 contacts with the toothless part of the transmission chain 423, at this time, the driven gear 422 no longer drives the transmission chain 423 to move, and then the transmission chain 423 no longer drives the baffle 430 to move, so that the baffle 430 can be fixed at the opening 300.

For another example, as shown in fig. 4D, a part of the teeth of the driven gear 422 may be removed, so that the driven gear 422 drives the transmission chain 423 to perform a meshing motion during the process of driving the transmission chain 423, for example, when the electronic device is opened from 0 degree to 70 degrees, the driven gear 422 drives the transmission chain 423 to perform a meshing motion, the baffle 430 slowly moves to block the opening, and the opening is completely blocked when the opening reaches 70 degrees; when the electronic device is opened from 70 degrees to 180 degrees, the toothless part of the driven gear 422 contacts with the transmission chain 423, and at this time, the driven gear 422 no longer drives the transmission chain 423 to move, that is, during the opening from 70 degrees to 180 degrees, the transmission chain 423 no longer drives the baffle 430 to move, so that the baffle 430 can be fixed at the opening 300.

It can be understood that the above angles are only for facilitating understanding, and specifically, in which angle ranges the baffle is hidden in the second portion, and in which angle ranges the baffle blocks the opening, those skilled in the art can specifically design according to actual conditions and the required opening and closing conditions of the electronic device.

Similarly, the above-mentioned manner is only to help understanding, and specifically, a part of the sprocket teeth on the transmission chain or a part of the gear teeth on the driven wheel may be removed, or both of them may be adopted, and the present invention is not limited herein, and those skilled in the art may specifically design according to actual situations and the required opening and closing situations of the electronic device.

According to the embodiment of the present disclosure, the baffle 430 includes an elastic portion, wherein the elastic member is in a compressed state when the baffle is hidden in the second portion, for example, the bump portion of the baffle 430 may be an elastic portion, that is, the bump portion of the baffle 430 may be made of an elastic material, and when the baffle 430 is hidden in the second portion, the bump is in a compressed state, and when the bump portion covers the opening 300, the bump portion is pressed due to no pressure, so that the bump is expanded due to the property of the elastic material, for example, the expanded bump portion is exactly located on the same plane as the C-cover.

In the disclosed embodiment, the transmission structure 420 may include, for example, a horizontal transmission structure and a vertical transmission structure.

When the angle between the first portion 100 and the second portion 200 satisfies a third threshold, the horizontal transmission structure drives the baffle to move.

Specifically, in the embodiment of the present disclosure, the third threshold may be 0 degree to 60 degrees as the first threshold, for example, when the electronic device is opened, that is, from 0 degree to 60 degrees, the rotating shaft 410 rotates relative to the second portion 200 and drives the driving gear 421 to rotate, the driving gear 421 drives the driven gear 422 to rotate, the driven gear 422 drives the transmission chain 423 to move, further, the transmission chain 423 drives the baffle 430 to move from the position hidden in the second portion 200, the horizontal transmission structure drives the baffle 430 to move to the position of the opening in parallel to the C-cover plane, and when the angle reaches 60 degrees, the baffle 430 is just under the opening.

When the angle between the first portion 100 and the second portion 200 satisfies a fourth threshold, the vertical transmission structure drives the baffle to move.

Specifically, in the embodiment of the present disclosure, the fourth threshold may be 60 degrees to 180 degrees as the second threshold, when the electronic device is at 60 degrees, the baffle 430 is just below the opening, at this time, during the opening process of 60 degrees to 180 degrees, the baffle 430 does not move horizontally any more, but the baffle is driven to move vertically by the vertical transmission structure, for example, the baffle may be moved upward until the upper surface of the baffle and the C-cover are located at the same plane position.

The horizontal transmission structure and the vertical transmission structure are not limited, and may be an elastic structure, a connecting rod transmission structure, a gear transmission structure, etc., and those skilled in the art may design according to actual situations.

In addition, in order to enable the baffle to accurately block the opening, so that a gap left between the baffle and the opening is small enough, and the C-cover surface of the electronic equipment is more attractive, the shell with the opening C-cover surface of the electronic equipment can be processed into a thinner shell, and therefore the gap between the baffle and the opening is reduced. Or, the surface of the baffle plate can be provided with other soft materials, such as sponge, when the baffle plate blocks the open hole, the sponge can block the gap between the baffle plate and the open hole, so that the open hole of the C-cover surface is smoother, and the aesthetic property of the electronic equipment is improved.

In the technical scheme of the embodiment of the disclosure, in the mechanical structure of the electronic device, the baffle is connected with the transmission structure, when the first part and the second part of the electronic device rotate relatively, the baffle can block the opening of the C-cover at the joint of the rotating shaft, so that the electronic device can realize more aesthetic design, and the baffle can block the opening of the C-cover at the joint of the rotating shaft, so that the electronic device has more novel appearance, and good visual experience is provided for users.
