[0031] See also Figure 1 , Figure 2 and Figure 3The embodiment of the present application provides a hinge mechanism 100, which is applied to an electronic device 300, and the electronic device 300 includes a first body 51 and a second body 52. ​​The hinge mechanism 100 includes a hinge base 10, a first rotating member 20, a second rotating member 30, and a linkage assembly 40. The first rotating member 20 and the second rotating member 30 are both rotatably connected to the hinge base 10, and the first rotating member 20 and the second rotating member 30 are respectively connected to the first body 51 and the second body 52, so as to drive the first body 51 and the second body 52 to expand or overlap. The linkage assembly 40 includes a first linkage member 41 and a second linkage member 42, the first linkage member 41 and the second linkage member 42 are both rotatably connected to the shaft base 10, the first linkage member 41 is linked to the second linkage member 42, the first linkage member 41 is provided with a first slider 414, the second linkage member 42 is provided with a second slider 424, the first rotating member 20 is provided with a first sliding portion 23 slidably matched with the first slider 414, the second rotating member 30 is provided with a second sliding portion 33 matched with the second slider 424, the first rotating member 20 rotates relative to the shaft base 10 to drive the first slider 414 to slide relative to the first rotating member 20, and follow the first rotating member 20 to rotate relative to the shaft base 10, the second rotating member 30 rotates relative to the shaft base 10 to drive the second slider 424 to slide relative to the second rotating member 30, and follow the second rotating member 30 to rotate relative to the shaft base 10, so that the first rotating member 20 rotates synchronously with the second rotating member 30 through the linkage assembly 40.

[0032] In the prior art, complex gear transmission mechanisms are usually used to achieve dual-axis synchronous rotation, but the manufacturing and assembly accuracy of the gears are very high. It is inevitable that when multiple gears are used for transmission, there is a center distance tolerance between adjacent gears, resulting in lost motion in the transmission of adjacent gears. For a multi-gear mechanism, the greater the accumulated lost motion error, the more difficult it is to achieve a high-precision synchronous transmission effect.

[0033] The rotating shaft base 10 is rotatably connected by the first linkage member 41 and the second linkage member 42. The first rotating member 20 is provided with a first sliding portion 23 that slidably cooperates with the first slider 414, and the second rotating member 30 is provided with a second sliding portion 33 that cooperates with the second slider 424. The first rotating member 20 rotates synchronously with the second rotating member 30 via the linkage assembly 40, that is, the first linkage member 41 is linked with the second linkage member 42. The first rotating member 20 can transmit torque to the second rotating member 30 via the first linkage member 41 and the second linkage member 42. Conversely, the second rotating member 30 can also transmit torque to the first rotating member 20 via the first linkage member 41 and the second linkage member 42. Therefore, the first rotating member 20 and the second rotating member 30 can achieve the effect of synchronous rotation, avoid the use of complex gear structures, reduce assembly errors, improve transmission accuracy and reduce costs.

[0034] When the first rotating member 20 rotates relative to the rotating shaft base 10, the first rotating member 20 can drive the first linkage member 41 to rotate relative to the rotating shaft base 10 through the cooperation of the first slider 414 and the first sliding part 23, and the rotation axis of the first rotating member 20 is parallel to the rotation axis of the first linkage member 41, wherein the first rotating member 20 transmits the rotational torque to the first slider 414, so that the first slider 414 follows the first rotating member 20 to rotate relative to the rotating shaft base 10 and slides relative to the first sliding part 23, thereby driving the first linkage member 41 to rotate relative to the rotating shaft base 10 around a direction parallel to the rotation axis of the first rotating member 20, thereby realizing the synchronous movement of the first rotating member 20 and the first linkage member 41 around different independent rotating shafts, with small assembly error and high synchronous movement accuracy.

[0035] When the second rotating member 30 rotates relative to the rotating shaft base 10, the second rotating member 30 can drive the second linkage member 42 to rotate relative to the rotating shaft base 10 through the cooperation of the second slider 424 and the second sliding part 33, and the rotation axis of the second rotating member 30 is parallel to the rotation axis of the second linkage member 42, wherein the second rotating member 30 transmits the rotation torque to the second slider 424, so that the second slider 424 follows the rotation of the second rotating member 30 relative to the rotating shaft base 10 and slides relative to the second sliding part 33, thereby driving the second linkage member 42 to rotate relative to the rotating shaft base 10 around the direction parallel to the rotation axis of the second rotating member 30, thereby realizing the synchronous movement of the second rotating member 30 and the second linkage member 42 around different independent rotating shafts, and the assembly error is small and the synchronous movement precision is high. In addition, through the linkage of the first linkage member 41 and the second linkage member 42, the effect of synchronous rotation of the first rotating member 20 and the second rotating member 30 can be achieved, reducing the assembly error, improving the transmission precision and reducing the cost.

[0036] It is understandable that the electronic device 300 can be a smart phone, a tablet computer, a smart watch, a laptop computer or a wearable smart device, etc. The electronic device 300 is a foldable structure, and the first body 51 can be flipped relative to the second body 52 through the hinge mechanism 100, so that the first body 51 can be overlapped or unfolded relative to the second body 52, thereby realizing two usage states. The first rotating member 20 and the second rotating member 30 are synchronously rotated relative to the hinge base 10 through the linkage assembly 40, and the first body 51 and the second body 52 are synchronously rotated relative to the hinge base 10, so that the rotation torque of the first body 51 and the second body 52 is balanced to meet the rotation torque requirements at various angles.

[0037] See also Figure 4 and Figure 5In this embodiment, the rotating shaft base 10 has two side plates 11 arranged opposite to each other, and a bottom plate 12 fixedly connected to the two side plates 11.

The receiving groove 13 provides installation space and rotation space for the first rotating member 20, the second rotating member 30, the first linkage member 41 and the second linkage member 42. The rotating shaft base 10 is also provided with a first bracket 14, a second bracket 15 and a third bracket 16. The first bracket 14, the second bracket 15 and the third bracket 16 are all located in the receiving groove 13. The first bracket 14, the second bracket 15 and the third bracket 16 can be fixedly connected to the bottom plate 12 by screw connection, welding or glue bonding, and can be set according to actual needs, which is not limited here. The first bracket 14 is used for rotationally connecting with the first rotating member 20, the second bracket 15 is used for rotationally connecting with the second rotating member 30, and the third bracket 16 is used for rotationally connecting with the first linkage member 41 and the second linkage member 42.

[0038] See also Figure 4 and Figure 5The first rotating member 20 is provided with a first rotating portion 21 and a first baffle 22 fixedly connected to the first rotating portion 21. The first rotating member 20 is rotatably connected to the shaft base 10 via the first rotating portion 21, wherein the first rotating portion 21 is rotatably connected to the first bracket 14. The first baffle 22 is in the shape of a flat plate, one end of the first baffle 22 is close to the shaft base 10, and the other end extends in a direction away from the shaft base 10.

The second rotating portion 31 is fixed to one end of the second baffle 32 close to the rotating shaft base 10. The second rotating portion 31 is a side plate fixed to the side of the second baffle 32. The second baffle 32 can rotate relative to the rotating shaft base 10 with the second rotating portion 31, so that the first baffle 22 can be turned over relative to the rotating shaft base 10, so as to be unfolded or overlapped with the second baffle 32. The first baffle 22 and the second baffle 32 are used to connect the first body 51 and the second body 52 respectively, so as to drive the first body 51 and the second body 52 to be unfolded or overlapped.

[0039] See also Figure 5 and Figure 6, the first linkage member 41 is in the shape of a long arm. One end of the first linkage member 41 is rotatably connected to the shaft base 10, and the other end is connected to the first baffle 22. The rotation axis of the first linkage member 41 is parallel to the rotation axis of the first rotating member 20. The length of the first linkage member 41 is greater than the distance between the rotation axis of the first linkage member 41 and the rotation axis of the first rotating member 20. The first baffle 22 is provided with a first rotating end 221 and a first connecting end 222 arranged relative to the first rotating end 221. The first rotating portion 21 is arranged at the first rotating end 221. The first connecting end 222 is used to connect the first main body 51.

When the first baffle 22 and the second baffle 32 rotate away from each other relative to the shaft base 10, the first linkage member 41 connected to one end of the first baffle 22 slides in a direction away from the first connecting end 222 and rotates relative to the first baffle 22, so as to drive the first linkage member 41 to rotate relative to the shaft base 10; when the first baffle 22 and the second baffle 32 rotate close to each other relative to the shaft base 10, the first linkage member 41 connected to one end of the first baffle 22 slides in a direction close to the first rotating end 221 and rotates relative to the first baffle 22, so as to drive the first linkage member 41 to rotate relative to the shaft base 10.

[0040] See also Figure 5 and Figure 6 The first baffle plate 22 is provided with a first slide groove 223, and the first baffle plate 22 is rotated and slidably matched with the first linkage member 41 through the first slide groove 223. The first slide groove 223 extends from the first rotating end 221 toward the direction close to the first connecting end 222.

Of course, in other embodiments, the first slide groove 223 can be set on the first linkage member 41, and the first baffle plate 22 is set on a slider matched with the first slide groove 223.

[0041] See also Figure 5 and Figure 7, the second linkage member 42 is in the shape of a long arm. One end of the second linkage member 42 is rotatably connected to the shaft base 10, and the other end is connected to the second baffle 32. The rotation axis of the second linkage member 42 is parallel to the rotation axis of the second rotating member 30. The length of the second linkage member 42 is greater than the distance between the rotation axis of the second linkage member 42 and the rotation axis of the second rotating member 30. The second baffle 32 is provided with a second rotating end 321 and a second connecting end 322 arranged relative to the second rotating end 321. The second rotating portion 31 is arranged at the second rotating end 321. The second connecting end 322 is used to connect the second body 52. ​​When the second baffle 32 rotates relative to the shaft base 10 with the second rotating portion 31, it can drive one end of the second linkage member 42 to rotate relative to the shaft base 10, and the other end to rotate and slide relative to the second baffle 32. When the first baffle 22 and the second baffle 32 rotate away from each other relative to the shaft base 10, the second linkage member 42 connected to one end of the first baffle 22 slides in a direction away from the second connection end 322 and rotates relative to the second baffle 32, so as to drive the second linkage member 42 to rotate relative to the shaft base 10; when the first baffle 22 and the second baffle 32 rotate close to each other relative to the shaft base 10, the second linkage member 42 connected to one end of the second baffle 32 slides in a direction close to the second rotating end 321 and rotates relative to the second baffle 32, so as to drive the second linkage member 42 to rotate relative to the shaft base 10.

[0042] See also Figure 5 and Figure 7 The second baffle plate 32 is provided with a second slide groove 323, and the second baffle plate 32 is rotationally and slidably matched with the second linkage member 42 through the second slide groove 323. The second slide groove 323 extends from the second rotating end 321 toward the direction close to the second connecting end 322.

[0043] See also Figure 8, the first linkage member 41 is provided with a first meshing portion 411 at one end close to the second linkage member 42. The second linkage member 42 is provided with a second meshing portion 421 at one end close to the first linkage member 41. The second meshing portion 421 meshes with the first meshing portion 411, thereby realizing the linkage between the first linkage member 41 and the second linkage member 42. The first meshing portion 411 and the second meshing portion 421 are both gear structures. The first meshing portion 411 can be an incomplete gear structure, that is, the first meshing portion 411 is provided with meshing teeth on a part of the periphery, and the second meshing portion 421 can be an incomplete gear structure, that is, the second meshing portion 421 is provided with meshing teeth on a part of the periphery. Of course, the first meshing portion 411 and the second meshing portion 421 can also be a complete gear structure. In other embodiments, the first linkage member 41 and the second linkage can also be linked in other ways, for example, by setting a transmission belt connecting the first linkage member 41 and the second linkage member 42, which can be set according to actual needs and is not limited here.

[0044] See also Figure 1 and Fig. 9 Further, the first linkage member 41 is provided with a first rotating shaft 412 and a first push rod 413 fixedly connected to the first rotating shaft 412, the first rotating shaft 412 is rotatably connected to the rotating shaft base 10, the first rotating shaft 412 is parallel to the rotation axis of the first rotating member 20, and the first slider 414 is arranged at the end of the first push rod 413 away from the first rotating shaft 412.

[0045] In this embodiment, the length direction of the first push rod 413 is perpendicular to the rotation axis of the first rotating shaft 412. One end of the first push rod 413 is fixedly connected to the first rotating shaft 412. The connection method of the first push rod 413 and the first rotating member 20 can refer to the previous description and will not be repeated here. The length of the first push rod 413 is greater than the distance between the rotation axis of the first rotating shaft 412 and the rotation axis of the first rotating member 20. When the first rotating member 20 rotates relative to the rotating shaft base 10, it can drive one end of the first push rod 413 to slide between the first rotating end 221 and the first connecting end 222, and drive the first rotating shaft 412 to rotate through the first push rod 413, so as to link with the second linkage member 42 to drive the second rotating member 30 to rotate synchronously. Since the first linkage member 41 is a composite structure of a rotating shaft and a push rod, the length of the first push rod 413 is relatively large, that is, the first push rod 413 can play the role of a labor-saving lever, which can reduce the rotation torque and reduce the rotation resistance, which is conducive to extending the service life of the rotating shaft.

[0046] See also Figure 1 and Fig.10Further, the second linkage member 42 is provided with a second rotating shaft 422 and a second push rod 423 fixedly connected to the second rotating shaft 422, the second rotating shaft 422 is rotatably connected to the rotating shaft base 10, the second rotating shaft 422 is parallel to the rotation axis of the second rotating member 30, the second rotating shaft 422 is linked to the first rotating shaft 412, and the second slider 424 is arranged at the end of the second push rod 423 away from the second rotating shaft 422.

[0047] In this embodiment, the length direction of the second push rod 423 is perpendicular to the rotation axis of the second rotating shaft 422. One end of the second push rod 423 is fixedly connected to the second rotating shaft 422. The connection method of the second push rod 423 and the second rotating member 30 can refer to the previous description, which will not be repeated here. The length of the second push rod 423 is greater than the distance between the rotation axis of the second rotating shaft 422 and the rotation axis of the second rotating member 30. When the second rotating member 30 rotates relative to the rotating shaft base 10, it can drive one end of the second push rod 423 to slide between the second rotating end 321 and the second connecting end 322, and drive the second rotating shaft 422 to rotate through the second push rod 423, so as to link with the first linkage member 41 to drive the first rotating member 20 to rotate synchronously. Since the second linkage member 42 is a composite structure of a rotating shaft and a push rod, the length of the second push rod 423 is relatively large, that is, the second push rod 423 can play the role of a labor-saving lever, which can reduce the rotation torque and reduce the rotation resistance, which is conducive to extending the service life of the rotating shaft.

[0048] The first rotating shaft 412 may be provided with meshing teeth to form a gear structure, and the second rotating shaft 422 may be provided with meshing teeth to form a gear structure, and the first rotating shaft 412 and the second rotating shaft 422 may be linked in a meshing manner. The first rotating shaft 412 and the second rotating shaft 422 are both miniature rotating shafts, and the size of the first rotating shaft 412 is smaller than the size of the first rotating part 21, and the size of the second rotating shaft 422 is smaller than the size of the second rotating part 31, so that the first rotating shaft 412 and the second rotating shaft 422 occupy a smaller arrangement space than the first rotating part 21 and the second rotating part 31. The first push rod 413 and the second push rod 423 are both long arm structures, and are both connected to the back side of the first baffle 22 and the second baffle 32, occupying a small internal space of the rotating shaft base 10, so that the overall size of the linkage assembly 40 is small, suitable for being arranged in a small-sized rotating shaft base 10, which is conducive to realizing the small size of the rotating shaft mechanism. The first rotating shaft 412 and the second rotating shaft 422 are driven to rotate synchronously by the long-arm-shaped first push rod 413 and the second push rod 423, respectively, so that the synchronous rotation torque of the first rotating member 20 and the second rotating member 30 is maintained at a relatively small level; in addition, in the present embodiment, the first push rod 413 and the second push rod 423 can meet the transmission requirements of large spacing, and there is no need to set up a complex multi-gear transmission structure. The structure is simple, the accumulated backlash error is small, and high-precision transmission requirements can be met.

[0049] See also Fig.11 and Fig.12 Furthermore, the shaft base 10 is provided with a receiving groove 13, the first shaft 412 and the second shaft 422 are both received in the receiving groove 13, and the plane formed by the rotation axis of the first rotating member 20 and the rotation axis of the second rotating member 30 is located on the side of the first rotating shaft 412 and the second rotating shaft 422 away from the bottom of the receiving groove 13.

[0050] In this embodiment, the receiving groove 13 is provided with an opening 131 and a bottom surface 132 opposite to the opening 131. The first rotating member 20 and the second rotating member 30 extend into the receiving groove 13 through the opening 131. The first bracket 14, the second bracket 15 and the third bracket 16 are all fixed to the bottom surface 132. The first bracket 14 and the second bracket 15 are rotatably connected to the first rotating member 20 and the second rotating member 30 respectively. The third bracket 16 is rotatably connected to the first rotating shaft 412 and the second rotating shaft 422. The plane formed by the rotation axis of the first rotating shaft 412 and the rotation axis of the second rotating shaft 422 is located between the bottom surface 132 and the plane formed by the rotation axis of the first rotating member 20 and the rotation axis of the second rotating member 30, wherein the distance between the plane formed by the rotation axis of the first rotating shaft 412 and the rotation axis of the second rotating member 30 and the bottom surface 132 is a first distance, and the distance between the plane formed by the rotation axis of the first rotating member 20 and the rotation axis of the second rotating member 30 and the bottom surface 132 is a second distance, and the first distance is smaller than the second distance.

[0051] The rotation axis of the first rotating shaft 412 and the rotation axis of the first rotating member 20 are spaced apart in a direction perpendicular to the bottom surface 132, and the rotation axis of the second rotating shaft 422 and the rotation axis of the second rotating member 30 are spaced apart in a direction perpendicular to the bottom surface 132, wherein the rotation axis of the first rotating shaft 412 and the rotation axis of the second rotating shaft 422 are relatively close to the bottom surface 132, and the rotation axis of the first rotating member 20 and the rotation axis of the second rotating member 30 are relatively far away from the bottom surface 132, so that the first rotating shaft 412 and the first rotating member 20 form a rotating shaft staggered structure with a height difference, and the second rotating shaft 42 2 and the second rotating member 30 form a rotating shaft staggered structure with a height difference. When the first body 51 and the second body 52 are flipped relative to the rotating shaft base 10 respectively, the first rotating member 20 and the first linkage member 41 can cooperate to meet the rotation damping requirements at different angles, so that the first body 51 can be suspended at any angle, and the rotation damping of the first body 51 can be ensured to change smoothly during the rotation process; the second rotating member 30 and the second linkage member 42 can cooperate to meet the rotation damping requirements at different angles, so that the second body 52 can be suspended at any angle, and the rotation damping of the second body 52 can be ensured to change smoothly during the rotation process.

[0052] See also Fig.13, further, the distance between the rotation axis of the first rotating shaft 412 and the rotation axis of the second rotating shaft 422 is smaller than the distance between the rotation axis of the first rotating member 20 and the rotation axis of the second rotating member 30. In this embodiment, the first rotating shaft 412 and the second rotating shaft 422 are both miniature rotating shafts, the size of the first rotating shaft 412 is smaller than the size of the first rotating part 21, and the size of the second rotating shaft 422 is smaller than the size of the second rotating part 31, so that the distance between the rotation axis of the first rotating shaft 412 and the rotation axis of the second rotating shaft 422 can be smaller than the distance between the rotation axis of the first rotating member 20 and the rotation axis of the second rotating member 30, so that the first rotating shaft 412 and the second rotating shaft 422 occupy a smaller arrangement space than the first rotating part 21 and the second rotating part 31. The first push rod 413 and the second push rod 423 are both long arm structures, connected to the back side of the first baffle plate 22 and the second baffle plate 32, occupying a small internal space of the shaft base 10, so that the overall size of the linkage assembly 40 is small, suitable for being arranged in a small-sized shaft base 10, which is conducive to realizing the small size of the shaft mechanism. The first push rod 413 and the second push rod 423 in the shape of long arms respectively drive the first shaft 412 and the second shaft 422 to rotate synchronously, so that the synchronous rotation torque of the first rotating member 20 and the second rotating member 30 is kept at a relatively small level; in addition, in this embodiment, the first push rod 413 and the second push rod 423 can meet the transmission requirements of large spacing, without the need to set a complex multi-gear transmission structure, with a simple structure and a small cumulative idle error, which can meet the transmission requirements of high precision.

[0054] In this embodiment, the first slider 414 and the second slider 424 are both cylindrical, and the first slider 414 is rotationally and slidably matched with the first slide groove 223 of the first rotating member 20. The second slider 424 is rotationally and slidably matched with the second slide groove 323 of the second rotating member 30. By making the first push rod 413 and the second push rod 423 have the same length, and the angle between the plane formed by the rotation axis of the first rotating shaft 412 and the rotation axis of the second rotating shaft 422 and the first push rod 413 is equal to the angle between the plane formed by the rotation axis of the first rotating shaft 412 and the rotation axis of the second rotating shaft 422 and the second push rod 423, the first push rod 413 and the second push rod 423 can be symmetrically arranged, and the relative direction of the second slider 424 and the first slider 414 can be parallel to the plane formed by the rotation axis of the first rotating member 20 and the rotation axis of the second rotating member 30. Since the first linkage member 41 is linked to the second linkage member 42, the first slider 414 and the second slider 424 can synchronously rotate and slide relative to the first rotating member 20 and the second rotating member 30, respectively, and the friction force of the first slider 414 relative to the first rotating member 20 and the friction force of the second slider 424 relative to the second rotating member 30 at least partially offset each other, thereby achieving torsional balance between the first rotating member 20 and the second rotating member 30 during the rotation process. In other embodiments, the first slider 414 and the second slider 424 can also be set in other shapes.

[0055] The sliding direction of the first sliding block 414 relative to the first rotating member 20 is perpendicular to the direction of the rotation axis of the first rotating member 20.

The first sliding groove 223 extends from the rotating end of the first baffle 22 toward the first connecting end 222, and the extending direction of the first sliding groove 223 is perpendicular to the rotation axis of the first rotating member 20. When the first baffle 22 and the second baffle 32 rotate away from each other relative to the rotating shaft base 10, the first sliding block 414 slides in a direction close to the first connecting end 222; when the first baffle 22 and the second baffle 32 rotate close to each other relative to the rotating shaft base 10, the first sliding block 414 slides in a direction close to the first rotating end 221. The first sliding block 414 slides back and forth in the first sliding groove 223 to generate friction force in a direction perpendicular to the axis of the first rotating member 20 , thereby meeting the rotation damping requirements of the first rotating member 20 at multiple angles, thereby ensuring a good rotation feel.

[0056] The sliding direction of the second slider 424 relative to the second rotating member 30 is perpendicular to the direction of the rotation axis of the second rotating member 30. The second baffle 32 is provided with a second slide groove 323, and the second baffle 32 rotates and slides with the second slider 424 through the second slide groove 323. The second slide groove 323 extends from the rotating end of the second baffle 32 toward the second connecting end 322, and the extending direction of the second slide groove 323 is perpendicular to the rotation axis of the second rotating member 30. When the first baffle 22 and the second baffle 32 rotate away from each other relative to the rotating shaft base 10, the second slider 424 slides in a direction close to the second connecting end 322; when the first baffle 22 and the second baffle 32 rotate close to each other relative to the rotating shaft base 10, the second slider 424 slides in a direction close to the second rotating end 321.

[0059] The first push rod 413 is at least partially located between the first sliding part 23 and the first rotating part 21, or located on the side of the first sliding part 23 away from the first rotating part 21, so that the first linkage member 41 can at least partially overlap with the first sliding part 23 and the first rotating part 21, thereby avoiding the first linkage member 41 from occupying the width dimension within the shaft base 10 and providing arrangement space for arranging the first rotating member 20 and the second rotating member 30.

[0060] See also Fig.15 Furthermore, the second rotating member 30 is provided with a second rotating portion 31, the second rotating portion 31 is rotatably connected to the rotating shaft base 10, the second rotating portion 31 and the second sliding portion 33 are arranged side by side in the direction of the rotation axis of the second linkage member 42, and the second linkage member 42 at least partially overlaps with the second sliding portion 33 and the second rotating portion 31.

[0061] In this embodiment, the second rotating member 30 is further provided with a second main body portion 34 fixedly connecting the second rotating portion 31 and the second sliding portion 33.

The rotation axis of the second rotating portion 31 is parallel to the rotation axis of the second linkage member 42. The second main body portion 34 and the second sliding portion 33 constitute the second baffle 32. The second slide groove 323 is formed between the second slide portion 33 and the second main body portion 34.

[0062] The second push rod 423 is at least partially located between the second sliding portion 33 and the second rotating portion 31, or located on the side of the second sliding portion 33 away from the second rotating portion 31, so that the second linkage member 42 can at least partially overlap with the second sliding portion 33 and the second rotating portion 31, thereby preventing the second linkage member 42 from occupying the arrangement space of the second rotating member 30, thereby preventing the first linkage member 41 from occupying the width dimension within the shaft base 10, and providing arrangement space for arranging the first rotating member 20 and the second rotating member 30.

The first linkage 41 at least partially overlaps with the first rotating part 21, and the second linkage 42 at least partially overlaps with the second rotating part 31. In the state where the first body 51 and the second body 52 are unfolded, the first rotating part 21 and the second rotating part 31 at least partially overlap, that is, the first rotating part 21 and the second rotating part 31 form a staggered structure, so that the distance between the rotation axis of the first rotating part 21 and the rotation axis of the second rotating part 31 is reduced, and the arrangement space occupied by the shaft base 10 is reduced. Furthermore, the first linkage member 41 and the second linkage member 42 are located within the interval between the first rotating portion 21 and the second rotating portion 31 , and there is no need to increase the width of the shaft base 10 to provide arrangement space, which is conducive to miniaturization of the shaft mechanism.

The first protruding structure 141 and the first connecting structure 211 are slidably matched, and the first connecting structure can slide along the arc relative to the first protruding structure 141, so that the first rotating part 21 can rotate relative to the first bracket 14, and the rotation axis of the first rotating part 21 coincides with the center of the first connecting structure 211. The first connecting structure 211 and the first protruding structure 141 both have a large radius, so that the rotational matching area of ​​the first rotating part 21 and the first bracket 14 is large, which is conducive to ensuring the smooth rotation of the first rotating part 21 relative to the first bracket 14 and ensuring the strength of the rotating shaft. In other embodiments, the first rotating portion 21 may also be in other shapes, which are not limited here. The first connecting structure 211 may be a protruding structure, and accordingly, a groove structure that rotates with the first connecting structure 211 may be provided on the first bracket 14 .

[0067] The second rotating part 31 is in the shape of a semicircular plate. The second rotating part 31 is provided with a second arc edge 312. The second arc edge 312 is a half arc. The second connecting structure 311 extends in a direction parallel to the second arc edge 312.

The second connecting structure 311 may be a protruding structure, and accordingly, a groove structure that is rotatably matched with the second connecting structure 311 may be provided on the second bracket 15 .

[0068] Since the radius of the first rotating part 21 and the second rotating part 31 is relatively large, in order to save the width dimension of the shaft base 10 occupied by the first rotating part 21 and the second rotating part 31, the first rotating part 21 and the second rotating part 31 are spaced apart on the shaft base 10, and the rotation axis of the first rotating part 21 and the rotation axis of the second rotating part 31 are parallel to the length direction of the shaft base 10, so that the rotation movement of the first rotating part 21 and the rotation movement of the second rotating part 31 do not interfere with each other, and the rotation axis of the first rotating part 21 and the second rotating part 31 are parallel to the length direction of the shaft base 10. The distance between the rotation axes of the two rotating parts 31 is smaller than the sum of the radius of the first connecting structure and the radius of the second connecting structure, which further reduces the distance between the rotation axes of the first rotating part 21 and the second rotating part 31. On the one hand, it is beneficial to save layout space and compress the width dimension of the shaft base 10; on the other hand, it can further reduce the distance between the rotation axis of the first rotating part 21 and the rotation axis of the first linkage member 41, and reduce the distance between the rotation axis of the second rotating part 31 and the rotation axis of the second linkage member 42, which is beneficial to reduce the rotational torque and improve user experience.
