[0053] The following further details the specific implementation manners of the present application with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and understanding the present application, and are not used to limit the present application.

[0054] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0055] Embodiment 1

[0056] Please refer to Figure 1 、 Figure 3 and Figure 4 , this embodiment provides a damping member 110, which can be used for the hinge 10 (such as Figure 5As shown in the figure, it provides damping for the rotation of the hinge 10.

[0057] The damper 110 provided in this embodiment includes: a connecting body 111 and a plurality of elastic sheet bodies 112. The elastic sheet bodies 112 are arranged along the length direction of the connecting body 111, and the elastic sheet bodies 112 are fixedly connected to the connecting body 111. All the elastic sheet bodies 112 together form a through damping cavity 113 along the length direction of the connecting body 111.

[0058] Applied to the hinge 10, the rotating shaft 200 in the hinge 10 is inserted into the damping cavity 113 and is in interference fit with the damping cavity 113. In this way, the elastic sheet body 112 can provide the damping (frictional damping) required for the rotation of the rotating shaft 200.

[0059] Among them, the connecting body 111 can be a strip-shaped structure, and each elastic sheet body 112 is fixedly arranged on the connecting body 111. Of course, the connecting body 111 can also be a multi-segment structure, and every two adjacent elastic sheet bodies 112 are fixedly connected through the connecting body 111.

[0060] Optionally, the fixed connection method can be selected as welding connection or riveting connection. It should be understood that the above fixed connection methods are only for illustrative purposes and do not limit the protection scope of this application.

[0061] Optionally, the elastic sheet bodies 112 are arranged at equal intervals along the length direction of the connecting body 111. In this way, it is ensured that after the rotating shaft 200 is installed, the resistance received during the rotation process is more uniform and the rotation feedback effect is better. Of course, in some embodiments, the elastic sheet bodies 112 can also be arranged at other intervals, not limited to the equal interval arrangement above.

[0062] The damper 110 provided in this embodiment integrates a plurality of elastic sheet bodies 112 into a whole component through the connecting body 111 and forms a damping cavity 113 for installing the rotating shaft 200. Among them, the rotating shaft 200 is in interference fit in the damping cavity 113. In this way, the integrated elastic sheet bodies 112 together provide damping for the rotation of the rotating shaft 200.

[0063] Compared with the prior art, integrating a plurality of elastic sheet bodies 112 into a whole component in this embodiment can effectively avoid the problem of looseness between the elastic sheet bodies 112 during use, thereby improving the reliability. In this way, when applied to the hinge 10, the service life of the hinge 10 can be extended. Moreover, the whole component reduces the number of overall parts, has a simpler structure and lower cost.

[0064] Embodiment Two

[0065] Please refer to Figure 1 and Figure 2 , this embodiment provides a damper 110 that can be used for the hinge 10 (such as Figure 5In the figure (not shown), it provides damping for the rotation of the hinge 10. This embodiment is an improvement based on the technical solution of the above-mentioned first embodiment. Compared with the above-mentioned first embodiment, the difference lies in that:

[0066] In this embodiment, the elastic sheet body 112 includes a first elastic arm 112a, a second elastic arm 112b, and a connecting portion 112c. The second elastic arm 112b is arranged opposite to the first elastic arm 112a. The connecting portion 112c is arranged between the first elastic arm 112a and the second elastic arm 112b, and one end of the connecting portion 112c is connected to the first elastic arm 112a, and the other end is connected to the second elastic arm 112b.

[0067] In this way, the space between the first elastic arm 112a and the second elastic arm 112b can be defined as the damping hole 112d of the elastic sheet body 112. The damping hole 112d is a non-closed hole, specifically forming a notch at the free ends of the first elastic arm 112a and the second elastic arm 112b.

[0068] The connecting portion 112c is fixedly connected to the connecting body 111, and the first elastic arm 112a and the second elastic arm 112b are of a cantilever structure. In this way, the damping holes 112d of all the elastic sheet bodies 112 together form a damping cavity 113 penetrating along the length direction of the connecting body 111.

[0069] It can be understood that both side walls 113a of the damping cavity 113 are a plurality of arranged first elastic arms 112a and a plurality of second elastic arms 112b. In this way, both sides of the damping cavity 113 can provide damping for the rotation of the rotating shaft 200, so that both sides of the rotating shaft 200 have a damping effect.

[0070] It should be noted that one of the first elastic arm 112a and the second elastic arm 112b can be designed as a fixed structure without elasticity, and interference fit with the rotating shaft 200 can also be achieved by one of the first elastic arm 112a and the second elastic arm 112b, as long as a damping hole 112d is formed between the first elastic arm 112a and the second elastic arm 112b.

[0071] In some embodiments, the elastic sheet body 112 is integrally U-shaped, or can also be understood as having a similar U-shaped structure. In this way, the fatigue resistance can be significantly improved and the service life can be extended through the large arm lengths of the first elastic arm 112a and the second elastic arm 112b.

[0072] Optionally, the connecting portion 112c, the first elastic arm 112a, and the second elastic arm 112b are connected as a whole, for example, formed as a whole by stamping, welding, casting, or other methods. It should be understood that the above processing methods are only for illustrative purposes and are not limitations on the protection scope of this application.

[0073] Optionally, the fixed connection method between the connecting portion 112c and the connecting body 111 can be selected as welding connection or riveting connection. Alternatively, the connecting portion 112c and the connecting body 111 can be cast as one body. It should be understood that the above fixed connection methods are only for illustrative purposes and do not limit the protection scope of the present application.

[0074] Furthermore, the connecting portion 112c is integrally connected to the first elastic arm 112a and the second elastic arm 112b through an arc transition. In this way, the connecting portion 112c is connected to the first elastic arm 112a and the second elastic arm 112b by an arc transition to form an integrated structure, thus effectively avoiding stress concentration at the connection.

[0075] Embodiment Three

[0076] Please refer to Figure 4 , this embodiment provides a damping member 110, which can be used in the hinge 10 to provide damping for the rotation of the hinge 10. This embodiment is an improvement based on the technical solution of the above Embodiment One. Compared with the above Embodiment One, the difference is that:

[0077] In this embodiment, the elastic sheet body 112 includes a fixing plate 112e and a plurality of third elastic arms 112f; the fixing plate 112e is connected to the connecting body 111, and the plurality of third elastic arms 112f are arranged opposite to the fixing plate 112e, and the plurality of third elastic arms 112f are arranged along the length direction of the connecting body 111 and fixedly connected to the connecting body 111.

[0078] Among them, the fixing plate 112e is a whole long strip plate, and the third elastic arm 112f is a cantilever structure. In this way, the damping cavity 113 is jointly formed between all the third elastic arms 112f and the fixing plate 112e.

[0079] Optionally, the connection between the third elastic arm 112f and the connecting body 111 is a welding connection or a riveting connection. Alternatively, the third elastic arm 112f can be cast as one body with the connecting body 111. It should be understood that the above connection methods are only for illustrative purposes and do not limit the protection scope of the present application.

[0080] Optionally, the connection between the fixing plate 112e and the connecting body 111 is a bolt connection, a welding connection or a riveting connection. Alternatively, the fixing plate 112e can be cast as one body with the connecting body 111. It should be understood that the above connection methods are only for illustrative purposes and do not limit the protection scope of the present application.

[0081] One side wall 113a of the damping cavity 113 of the damping member 110 provided in this embodiment is a plane, and the other side wall 113a is a plurality of arranged third elastic arms 112f. In this way, after the rotating shaft 200 is installed, the damping cavity 113 mainly provides damping for the rotating shaft 200 through the third elastic arms 112f to adapt to the damping requirements of different products.

[0082] Example 4

[0083] Please refer to Figure 1 、 Figure 2 and Figure 3 , this embodiment provides a damping module 100, which can be applied to the hinge 10 to provide damping for the hinge 10.

[0084] In this embodiment, the damping module 100 includes a base 120 and a first damping member 110a. Among them, the base 120 is provided with the first damping member 110a on at least one of the two sides in its own width direction. That is to say, the damping module 100 has a damping cavity 113 for installing the rotating shaft 200 on at least one of the two sides in the width direction of the base 120. As Figure 3 shown, this embodiment shows that the first damping members 110a are provided on both sides of the base 120 in its own width direction, and the damping module 100 has two damping cavities 113.

[0085] The first damping member 110a can be selected as the damping member 110 provided according to any one of the above-mentioned Embodiment 1 to Embodiment 3. Among them, the connecting body 111 in the first damping member 110a is fixedly connected or integrally formed with the base 120.

[0086] In some embodiments, the fixed connection method between the connecting body 111 and the base 120 can adopt welding connection or riveting connection.

[0087] In some other embodiments, the integral molding of the connecting body 111 and the base 120 can be realized by casting. It should be understood that the above connection methods are only for illustration and are not limitations on the protection scope of this application.

[0088] Please refer to Figure 5 、 Figure 6 and Figure 6 , in some embodiments, the damping module 100 further includes a second damping member 110b. The second damping member 110b can be selected as the damping member 110 provided according to any one of the above-mentioned Embodiment 1 to Embodiment 3, and the second damping member 110b is embedded in the first damping member 110a.

[0089] Among them, the elastic sheet body 112 in the second damping member 110b is received between two adjacent elastic sheet bodies 112 in the first damping member 110a.

[0090] In some embodiments, in order to sufficiently increase the frictional force between the first damping member 110a and the second damping member 110b and the rotating shaft 200, and to achieve more convenient installation, the structure of the second damping member 110b is set to be the same as that of the first damping member 110a. After installation, the damping chambers 113 of the first damping member 110a and the second damping member 110b coincide, and the wall surfaces of the side walls 113a on at least one side of the damping chamber 113 are flush.

[0091] In this way, through the combination of the first damping member 110a and the second damping member 110b, the interference contact area between the damping chamber 113 and the rotating shaft 200 can be effectively increased, thereby increasing the frictional force. In other words, when the damping of a single first damping member 110a cannot meet the requirements, damping compensation is performed by adding the second damping member 110b. Moreover, the damping (frictional force) magnitude can be adjusted by replacing the second damping member 110b with different damping (different materials, different elastic arm sizes, or other ways to form the second damping member 110b with different damping).

[0092] Furthermore, the connection body 111 in the second damping member 110b and the connection body 111 in the first damping member 110a are fixedly connected or detachably connected. The connection body 111 in the second damping member 110b and the connection body 111 in the first damping member 110a can be selectively connected by a direct fixing method or a detachable method to limit the relative rotation of the second damping member 110b with respect to the first damping member 110a and ensure the stability of the structure during use.

[0093] Specifically, the fixed connection method between the connection body 111 in the second damping member 110b and the connection body 111 in the first damping member 110a can be selected as welding connection or riveting connection. Or, the connection body 111 in the second damping member 110b and the connection body 111 in the first damping member 110a are cast as one body. It should be understood that the above fixed connection methods are only for illustrative purposes and do not limit the protection scope of the present application. Welding connection or riveting connection.

[0094] Another specific case is that the connection body 111 in the second damping member 110b and the connection body 111 in the first damping member 110a can be selected for detachable connection, including but not limited to snap connection, screw connection, etc. In this way, the damping force can be adjusted by removing the number of damping members, and the installation and disassembly are convenient.

[0095] It should be noted that only the case of the superposition use of the two damping members 110, namely the second damping member 110b and the first damping member 110a, is described in this embodiment, which is also applicable to the superposition use of more than two damping members 110 and will not be described in detail in this embodiment.

[0096] Embodiment Five

[0097] Please refer toFigure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 10 , this embodiment provides a hinge 10, which can be used in a folding product to realize the rotational opening and closing between the main product part 20 and the auxiliary product part 30 of the folding product. The hinge 10 includes a rotating shaft 200 and a damping module 100 provided according to Embodiment 4. Among them, the rotating shaft 200 is inserted into the corresponding damping cavity 113 and has an interference fit with the damping cavity 113.

[0098] Please refer to Figure 7 and Figure 8 , optionally, the cross-sectional shape of the rotating shaft 200 along the radial direction is a cross shape, a toothed shape, a spline shape, a diamond shape, a circular shape, a corrugated shape or other shapes, as long as it can always maintain an interference fit with the inner wall of the damping cavity 113 and can provide friction. Those skilled in the art can understand that the inner wall of the elastic sheet body can also be set into other shapes such as a toothed shape and a corrugated shape, and the rotating shaft and the elastic sheet body can be meshed with each other to achieve hovering at any angle.

[0099] Please refer to Figure 5 , Figure 8 and Figure 9 , further, the hinge 10 further includes a rotating body 300, a connecting block 400 and a pull rod 500.

[0100] There are two rotating bodies 300, and each rotating body 300 has a non-rotating fit with both ends of the corresponding rotating shaft 200. In other words, there is no relative rotation between the rotating shaft 200 and the rotating body 300, and when the rotating shaft 200 rotates, it will drive the rotating body 300 to swing. For example, a non-rotating fit can be achieved by using a flat key, a spline or a concave-convex structure.

[0101] There are two connecting blocks 400, and each connecting block 400 is sleeved on the rotating body 300 and can slide relative to the rotating body 300. The connecting block 400 is used to connect to the main product part 20 or the auxiliary product part 30 of the folding product.

[0102] A pull rod 500 is provided at both ends of each rotating body 300. One end of the pull rod 500 is pivotally connected to the base 120 in the damping module 100, and the other end is pivotally connected to the connecting block 400.

[0103] In this way, when it is necessary to open or close the main product part 20 and the auxiliary product part 30, the main product part 20 or the auxiliary product part 30 will drive the connecting block 400 to swing. Under the action of the pull rod 500, the connecting block 400 will drive the rotating body 300 to swing, and the rotating body 300 will slide relative to the connecting block 400. When the rotating body 300 swings, it will drive the rotating shaft 200 to rotate in the corresponding damping cavity 113.

[0104] In some embodiments, a decorative cover 600 is further provided on the base 120 of the hinge 10, which protects the hinge 10 on the one hand and improves the aesthetics on the other hand.

[0105] Please refer to Figure 10 and Figure 11 together. Further, in this embodiment, a folding product is also provided. The folding product includes a main product part 20, a secondary product part 30, and the hinge 10 provided as above. The main product part 20 and the secondary product part 30 are connected by at least one hinge 10.

[0106] Compared with the prior art, the hinge 10 provided in this embodiment has the following advantages:

[0107] a. There is no cam mechanism. The rotating shaft 200 rotates in the damping cavity 113 formed by the elastic sheet body 112, and arbitrary angle hovering can be achieved through the frictional damping or mutual engagement between the elastic sheet body 112 and the rotating shaft 200.

[0108] b. The damping member 110 is an integral body, which combines all the elastic sheets into one part, which can not only achieve elasticity but also ensure strength. The elastic body is designed in a U-shaped structure to extend the arm length of the elastic arm, significantly improving fatigue resistance and increasing the service life.

[0109] c. The axial clearance space of the elastic body in the damping member 110 is fully utilized. Another damping member 110 can be inserted into the damping hole 112d in the damping member 110. Altogether, there are two parts, which can achieve damping compensation and can also achieve friction (damping) adjustment.

[0110] d. The connecting block 400 drives the four pull rods 500 and the rotating body 300 to rotate, and the rotating body 300 slides in the connecting block 400 to achieve overall linkage.
