Slip mechanism

The present invention relates to a slip mechanism, and more particularly to a slip mechanism for use in a sliding electronic device.

With the development of electronic technology and communication technology, consumer electronic devices such as mobile phones and PDAs (personal digital assistants) have become more and more widely used. Among them, the sliding type electronic device is slidably opened and closed in two parts, has a small volume and a novel structure, and is especially favored by many consumers.

The sliding mechanism commonly used in the sliding electronic device includes two fixing plates respectively fixed on the sliding cover and the body of the sliding electronic device, and a spring disposed between the two fixing plates, and the two fixed plates are provided with The two ends of the spring are respectively fixed to the two fixing plates by rivets.

When the two parts of the sliding electronic device are in a relatively closed state, the spring is in a natural state. When the sliding cover of the sliding electronic device is slid relative to the body, the spring begins to deform. When the sliding cover slides to a certain point, the spring occurs. The elastic deformation reaches a maximum. After continuing to push the slider over this point, the elastic deformation of the spring is gradually reduced. At this time, no need to manually push, the sliding cover can continue to slide under the elastic restoring force of the elastic member until the sliding cover is completely slid open relative to the body and the spring is restored. Natural state. When the sliding portion is pushed to close relative to the body, the elastic member is first elastically deformed, and gradually returns to a natural state after a certain point.

Although the sliding electronic device can realize semi-automatic control by elastic recovery of the elastic member, the spring is in a natural state when the sliding cover and the body are in a relatively sliding or closed state, and the spring is opposite to the sliding cover and the body. The elastic force is not provided, and the sliding cover cannot be stably opened or closed relative to the main body, and the sliding electronic device must increase the magnetic component, the positioning mechanism, etc. to position the sliding cover and the body, and the structure is relatively complicated.

In view of the above, it is necessary to provide a sliding mechanism which is simple in structure and can ensure that the two parts of the sliding type electronic device are stably in a completely sliding or closed state.

A sliding mechanism includes a body, a sliding cover slidably disposed on the body, and an elastic member disposed between the body and the sliding cover, wherein the two sides of the body are fixed with a bendable deformable sliding rail, and the elastic member is strip-shaped and The first fixing portion, the second fixing portion and the third fixing portion are disposed thereon, the first fixing portion and the second fixing portion are fixed on the sliding rail, and the third fixing portion is fixed on the sliding cover. At this time, the elastic member is sandwiched by the slide rails on both sides of the body to be bent and deformed.

Another sliding mechanism includes a body, a sliding cover slidably disposed on the body, and an elastic member disposed between the body and the sliding cover. The two sides of the body are provided with a bendable deformable sliding rail, and the elastic member is strip-shaped. The two ends are respectively fixed on the sliding rail, and the middle portion of the elastic member is fixed to the sliding cover. When the elastic member is in a natural state, the length between the two ends is greater than the distance between the two sides of the body.

In the above sliding mechanism, when the elastic member is installed between the main body and the sliding cover, since the length between the two ends of the elastic member is greater than the distance between the two sides of the main body, it is applied by the sliding rails on the two sides of the main body. The clamping force is bent and deformed, and is stable only when it is bent to the two sides to the maximum amount of deformation. And because there is a part between the two ends of the elastic member fixed to the slip The cover is also stably placed under the driving of the elastic member at one end of the two ends of the body without additional positioning mechanism, and the structure is simple. When the sliding cover is slid relative to the body, the sliding rails on the two sides may undergo a certain bending deformation, so that the elastic member can be extended to a certain length on both sides, so that the sliding cover does not lock during the sliding process.

Referring to FIG. 1 and FIG. 2 , the sliding mechanism 100 includes a body 10 , a sliding cover 30 slidably disposed on the body 10 , and an elastic member 50 disposed between the body 10 and the sliding cover 30 .

Referring to FIG. 2 and FIG. 3 together, the body 10 includes a fixed cover 11 and two rod-shaped slide rails 13 fixed to two sides of the fixed cover 11.

The fixing cover 11 is substantially a plate-like structure, and two ends thereof form two baffles 111 through which the sliding rails 13 pass, and a uniform perforation 1111 is formed in each of the baffles 111 near the two ends. Two auxiliary limiting portions 113 are respectively protruded on two sides of the fixing cover 11 , and an end of each auxiliary limiting portion 113 is recessed to form an arc-shaped groove 1131 . In the embodiment, the auxiliary positioning unit 113 is a claw. Of course, the auxiliary limiting portion 113 can also be other structures, such as a tab-like protruding portion having a through hole at the end, a hook protruding from the two sides of the fixing cover 11, and the like, and the number of the auxiliary limiting portion can also be Need to set.

The slide rail 13 is a stepped rod-like structure including a first shaft section 131, a second shaft section 133, a third shaft section 135 and a limiting portion 137 fixed to the second shaft section 133. The first shaft segment 131 is the same diameter as the third shaft segment 135 and larger than the diameter of the second shaft segment 133. The second shaft segment 133 can be bent and deformed, but the stiffness coefficient is greater than the stiffness coefficient of the elastic member 50, that is, elasticity. The force required for the piece 50 is greater than that of the deformation. A receiving groove 1371 is formed in the limiting portion 137. In the present embodiment, the stopper portion 137 has a claw structure. The limiting portion 137 may also have other structures, such as a tab protruding from the second shaft segment 133 and having a through hole, and a clamping member disposed on the second shaft segment 133 and having an elastic clamping function. .

The sliding cover 30 has a substantially plate-like structure, and a central portion is provided with a holding portion 31. Four lugs 33 are protruded from the four corners, and a plurality of connecting holes 331 are defined in each of the lugs 33. In the present embodiment, the catching portion 31 is a latching hole formed in the slide cover 30.

The elastic member 50 is a strip-like structure including a reed portion 51, a first positioning portion 53 formed at both ends of the reed portion 51, a second positioning portion 55, and a third positioning portion 57 formed at a central portion of the reed portion 51. The first positioning portion 53 and the second positioning portion 55 are located on the same side of the spring portion 51, and the third positioning portion 57 is located on the other side of the spring portion 51. The reed portion 51 forms a protrusion 511 adjacent to the first positioning portion 53 and the second positioning portion 55, respectively. The elastic member 50 is integrally molded from plastic. In the present embodiment, the first positioning portion 53 , the second positioning portion 55 , and the third positioning portion 57 are both pillar structures. The elastic member 50 is linear or curved in a natural state, but the length between the first fixing portion 53 and the second fixing portion 55 is greater than the two sides of the body 10 when it is linear or curved. The distance between the slide rails 13.

In the sliding mechanism 100, the first shaft portion 131 and the third shaft portion 135 of the slide rail 13 of the main body 10 are inserted through the through hole 1111 of the baffle 111 of the fixed cover 11 and partially embedded in the auxiliary limiting portion 113. Inside the groove 1131. The lug 33 of the slider 30 is sleeved on the slide rail 13 and slidable relative to the slide rail 13. The first positioning portion 53 and the second positioning portion 55 of the elastic member 50 are inserted into the receiving groove 1371 of the limiting claw 137 of the sliding rail 13 , and the third positioning portion 57 is inserted into the sliding cover 30 . Part 31. The projection 511 on the reed portion 51 of the elastic member 50 is in contact with the fixing cover 11. Because the length between the first fixing portion 53 and the second fixing portion 55 is greater than the distance between the sliding rails 13 on the two sides of the body 10 in the natural state of the elastic member 50, the elastic member 50 is mounted on the body 10 and the sliding cover 30. During the interval, the two ends are further curved to be curved by the clamping force.

Referring to FIG. 4, when the two parts of the sliding electronic device using the sliding mechanism 100 are in a closed state, the sliding cover 30 is held at one end of the body 10, and the elastic member 50 is in a state of maximum deformation, and the elastic state is obtained at this time. The reed portion 51 of the member 50 has the largest curvature. The elastic member 50 is stably in this state due to the clamping force of the slide rails 13 on both sides of the body 10, so that the slide cover 30 is also stably in this position.

The slider 30 is pushed to slide along the slide rail 13 relative to the body 10. The slide cover 30 drives the third fixing portion 57 of the elastic member 50 to move together, and the first fixing portion 53 and the second fixing portion 55 of the elastic member 50 are fixed. It is connected to the slide rails 13 on both sides without moving together with the third fixing portion 57.

Referring to FIG. 2 to FIG. 5, as the sliding cover 30 slides, the elastic member 50 firstly extends to the two sides and applies a resisting force to the sliding rail 13, and the second shaft segment 133 of the sliding rail 13 acts on the resisting force. Bending down to the two sides and bending deformation occurs. Since the abutting force applied by the elastic member 50 to the slide rails 13 on both sides is insufficient to cause a large bending deformation of the slide rail 13, when the second shaft segment 133 is bent to the maximum deformation amount, the elastic member 50 is undulated. Deformation, that is, close to the first The portion of the three fixing portions 57 moves under the driving of the slide cover 30, and forms a second arc portion at a portion close to the first fixing portion 53 and the second fixing portion 55. At this time, the elastic member 50 is deformed irregularly and is in an unstable state.

When the slider 30 is continuously pushed to slide, the two arc segments of the first fixing portion 53 and the second fixing portion 55 of the elastic member 50 are passed over the connection between the first fixing portion 53 and the second fixing portion 55, due to the elastic member. The two sides of the 50 are always subjected to the clamping force of the slide rail 13 and the slide rail 13 has a tendency to restore the state before the deformation, so that the elastic member 50 is automatically curved in an arc direction opposite to the original bending direction. The slider 30 applies a further thrust. The sliding cover 30 automatically slides under the elastic force of the elastic member 50 until the bending deformation of the sliding rail 13 completely disappears, and the sliding cover 30 slides and is held at the other end of the body 10 (as shown in FIG. 6).

In the sliding mechanism 100, when the sliding cover 30 is held at the two ends of the body 10, the elastic member 50 has the largest curvature, and the elastic member 50 is between the first fixing portion 53 and the second fixing portion 55 in the natural state. The length is greater than the distance between the two sides of the body 10, so that the elastic member 50 can be stably bent toward one end of the two ends of the body 10 under the clamping force of the two sides of the body 10, so that the sliding cover 30 can be stably Resisting one of the two ends of the body 10 ensures that the two portions of the sliding electronic device using the sliding mechanism 100 are stably in a relatively closed or sliding state without additional positioning mechanism or the like, and the structure is relatively simple.

The sliding rails 13 on the two sides of the main body 10 can be deformed to a certain extent, so that the elastic member 50 can extend to a certain length on both sides when the sliding cover 30 is moved, so that the elastic member 50 can not be locked in the intermediate position and cannot be crossed.

In the sliding mechanism 100, when the curved bending formed on the elastic member 50 near the first fixing portion 53 and the second fixing portion 55 crosses the connection between the first fixing portion 53 and the second fixing portion 55, no manual action is required. The elastic force of the elastic member 50 can drive the sliding cover 30 to continue sliding. Semi-automatic control.

The first fixing portion 53 , the second fixing portion 55 and the third fixing portion 57 are integrally formed on the elastic member 50 , and the two ends are fixedly connected to the body 10 by the first fixing portion 53 and the second fixing portion 55. The third fixing portion 57 fixes a certain portion between the two ends to the sliding cover 30, thereby eliminating the rivets used when the conventional elastic member is connected with the body 10 and the sliding cover 30, thereby reducing parts and reducing costs.

The elastic member 50 is made of a plastic material, and can be molded in a plurality of holes when integrally formed, and the production is convenient, and the quality of the elastic member 50 is small, which is advantageous for reducing the overall quality of the sliding mechanism 100.

The elastic member 50 has a strip-like structure. When it is installed between the body 10 and the sliding cover 30, it does not exist in the case where a conventional compression spring has a certain diameter and must consider the size of the space. The elastic member 50 of the strip structure occupies The small space is advantageous for the thin design of the slip mechanism 100.

The spring portion 51 of the elastic member 50 is convexly disposed on one side of the body 10 to ensure that the elastic member 50 and the body 10 are only in point contact, which reduces friction during the sliding of the sliding cover 30 relative to the body 10. .

The auxiliary limiting portion 113 is added to the fixing cover 11 of the body 10 to increase the strength of the sliding rail 13.

In addition, when the third fixing portion 57 of the strip-shaped elastic member 50 is not on the line connecting the first fixing portion 53 and the second fixing portion 55, the tendency of bending to any one of the two ends of the body 10 is compared. When the sliding cover 30 and the elastic member 50 are pushed over the position, the elastic member 50 drives the sliding cover 30 to rapidly slide to one end of the two ends of the body 10, and the hand feels better in one step.

It can be understood that in the sliding mechanism 100, the two ends of the elastic member 50 can also form an area. The second two protrusions are respectively formed on the two protrusions, and the first fixing portion 53 and the second fixing portion 55 are formed in a hole shape. Correspondingly, a two-column-shaped limiting portion 137 is formed on the two sliding rails 13 to cooperate with the first fixing portion 53 and the second fixing portion 55 having a hole shape.

It can be understood that the third fixing portion 57 on the elastic member 50 can also be a hole formed in the elastic member 50, and the sliding cover 30 correspondingly forms a convex column-shaped holding portion 31.

It can be understood that the slide rails 13 on the two sides of the body 10 can also be omitted, and the two ends of the elastic member 50 are directly fixed to the fixed cover 11 of the body 10 on the two sides.

In summary, the present invention complies with the requirements of the invention patent, and submits a patent application according to law.
