[0031] Please refer to Figure 1 、 Figure 2 and Figure 3, an embodiment of the present application provides a rotating shaft mechanism 100, which is applied to an electronic device 300. The electronic device 300 includes a first main body 51 and a second main body 52. The rotating shaft mechanism 100 includes a rotating shaft 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 rotating shaft base 10. The first rotating member 20 and the second rotating member 30 are respectively connected to the first main body 51 and the second main body 52 to drive the first main body 51 and the second main body 52 to unfold or overlap each other. 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 rotating shaft base 10. The first linkage member 41 and the second linkage member 42 are linked to each other. The first linkage member 41 is provided with a first slider 414, and 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 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. When the first rotating member 20 rotates relative to the rotating shaft base 10, it drives the first slider 414 to slide relative to the first rotating member 20 and rotates relative to the rotating shaft base 10 following the first rotating member 20. When the second rotating member 30 rotates relative to the rotating shaft base 10, it drives the second slider 424 to slide relative to the second rotating member 30 and rotates relative to the rotating shaft base 10 following the second rotating member 30, 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, a complex gear transmission mechanism is usually adopted to achieve dual-axis synchronous rotation, but the manufacturing precision and assembly precision requirements for gears are very high. Inevitably, when multiple gears are used for transmission, due to the center distance tolerance between adjacent gears, there is a dead zone in the transmission between adjacent gears. For a multi-gear mechanism, the accumulated dead zone error is larger, and it is difficult to achieve a high-precision synchronous transmission effect.

[0033] The first linkage 41 and the second linkage 42 are both rotatably connected to the rotating shaft base 10. 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 41 is linked with the second linkage 42. The first rotating member 20 can transmit torque to the second rotating member 30 via the first linkage 41 and the second linkage 42. Conversely, the second rotating member 30 can also transmit torque to the first rotating member 20 via the first linkage 41 and the second linkage 42. Thus, the first rotating member 20 and the second rotating member 30 can achieve the effect of synchronous rotation, which can avoid using a complex gear structure, 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 41 to rotate relative to the rotating shaft base 10 through the cooperation of the first slider 414 and the first sliding portion 23. And the rotation axis of the first rotating member 20 is parallel to the rotation axis of the first linkage 41. Wherein, the first rotating member 20 transmits rotational torque to the first slider 414, so that the first slider 414 slides relative to the first sliding portion 23 while following the first rotating member 20 to rotate relative to the rotating shaft base 10, realizing driving the first linkage 41 to rotate relative to the rotating shaft base 10 around the 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 41 around different independent rotating shafts, with small assembly errors 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 portion 33. 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 rotational torque to the second slider 424, so that the second slider 424 rotates relative to the rotating shaft base 10 following the second rotating member 30 and slides relative to the second sliding portion 33, realizing 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, with small assembly errors and high synchronous movement precision. Also, through the linkage between 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 assembly errors, improving transmission precision and reducing costs.

[0036] It can be understood that the electronic device 300 can be a smart phone, a tablet computer, a smart watch, a notebook computer or a wearable smart device, etc. The electronic device 300 has a foldable structure. The first main body 51 can be flipped relative to the second main body 52 through the rotating shaft mechanism 100, realizing the superposition or unfolding of the first main body 51 relative to the second main body 52, thereby realizing two usage states. Through the synchronous rotation of the first rotating member 20 and the second rotating member 30 relative to the rotating shaft base 10 through the linkage assembly 40, the first main body 51 and the second main body 52 rotate synchronously relative to the rotating shaft base 10, making the rotational torques of the first main body 51 and the second main body 52 balanced to meet the rotational torque requirements at various angles.

[0037] Please refer to Figure 4 and Figure 5, in this embodiment, the two side plates 11 of the rotating shaft base 10 are oppositely arranged, and the bottom plate 12 fixedly connecting the two side plates 11. The two side plates 11 and the bottom plate 12 enclose a receiving groove 13.

The rotating shaft base 10 is further 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 means such as screw connection, welding or glue bonding, which can be set according to actual needs and are not limited herein. The first bracket 14 is used for rotatably connecting with the first rotating member 20, the second bracket 15 is used for rotatably connecting with the second rotating member 30, and the third bracket 16 is used for rotatably connecting with the first linkage member 41 and the second linkage member 42.

[0038] Please refer to Figure 4 and Figure 5, the 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 rotationally connected to the rotating shaft base 10 via the first rotating portion 21, wherein the first rotating portion 21 is rotationally 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 rotating shaft base 10, and the other end extends in a direction away from the rotating shaft base 10. The first rotating portion 21 is fixed to one end of the first baffle 22 close to the rotating shaft base 10. The first rotating portion 21 is a side plate fixed to the side of the first baffle 22. The first baffle 22 can rotate relative to the rotating shaft base 10 along with the first rotating portion 21. The second rotating member 30 is provided with a second rotating portion 31 and a second baffle 32 fixedly connected to the second rotating portion 31. The second rotating member 30 is rotationally connected to the rotating shaft base 10 via the second rotating portion 31, and the rotation axis direction of the second rotating member 30 is parallel to the rotation axis direction of the first rotating member 20, wherein the second rotating portion 31 is rotationally connected to the second bracket 15. The second baffle 32 is in the shape of a flat plate, one end of the second baffle 32 is close to the rotating shaft base 10, and the other end extends in a direction away from the rotating 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 along with the second rotating portion 31, so that the first baffle 22 is flipped relative to the rotating shaft base 10 to be unfolded or superposed with the second baffle 32. The first baffle 22 and the second baffle 32 are used to connect the first main body 51 and the second main body 52 respectively to drive the first main body 51 and the second main body 52 to be unfolded or superposed with each other.

[0039] Please refer to Figure 5 and Figure 6, the first linkage 41 is in the shape of a long arm. One end of the first linkage 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 41 is parallel to the rotation axis of the first rotating member 20. The length of the first linkage 41 is greater than the distance between the rotation axis of the first linkage 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 disposed opposite to the first rotating end 221. The first rotating portion 21 is disposed 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 rotates relative to the shaft base 10 with the first rotating portion 21, it can drive one end of the first linkage 41 to rotate relative to the shaft base 10, and the other end to rotate and slide relative to the first baffle 22. When the first baffle 22 rotates away from the second baffle 32 relative to the shaft base 10, the end of the first linkage 41 connected to 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 41 to rotate relative to the shaft base 10; when the first baffle 22 rotates closer to the second baffle 32 relative to the shaft base 10, the end of the first linkage 41 connected to the first baffle 22 slides in a direction closer to the first rotating end 221 and rotates relative to the first baffle 22, so as to drive the first linkage 41 to rotate relative to the shaft base 10.

[0040] Please refer to Figure 5 and Figure 6 , the first baffle 22 is provided with a first chute 223, and the first baffle 22 is rotationally and slidably engaged with the first linkage 41 through the first chute 223. The first chute 223 extends from the first rotating end 221 towards the first connecting end 222. The first chute 223 can extend in a straight line or in a curve, and can be set according to actual needs. Of course, in other embodiments, the first chute 223 can be provided on the first linkage 41, and the first baffle 22 is provided with a slider that mates with the first chute 223.

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

[0042] Please refer to Figure 5 and Figure 7 , the second baffle 32 is provided with a second chute 323. The second baffle 32 is rotationally and slidably engaged with the second linkage 42 through the second chute 323. The second chute 323 extends from the second rotating end 321 towards the second connecting end 322. The second chute 323 can extend linearly or curvilinearly, and can be set according to actual needs. Of course, in other embodiments, the second chute 323 can be provided on the second linkage 42, and the second baffle 32 is provided with a slider that mates with the second chute 323.

[0043] Please refer to Figure 8, one end of the first linkage member 41 close to the second linkage member 42 is provided with a first meshing portion 411. One end of the second linkage member 42 close to the first linkage member 41 is provided with a second meshing portion 421. The second meshing portion 421 meshes with the first meshing portion 411, so as to realize the linkage between the first linkage member 41 and the second linkage member 42. Both the first meshing portion 411 and the second meshing portion 421 are gear structures. The first meshing portion 411 may be an incomplete gear structure, that is, the first meshing portion 411 is provided with meshing teeth on a partial circumference, and the second meshing portion 421 may be an incomplete gear structure, that is, the second meshing portion 421 is provided with meshing teeth on a partial circumference. Of course, the first meshing portion 411 and the second meshing portion 421 may also be complete gear structures. In other embodiments, the first linkage member 41 and the second linkage may also be linked in other ways. For example, by providing a transmission belt connecting the first linkage member 41 and the second linkage member 42, it can be set according to actual needs and will not be limited herein.

[0044] Please refer to Figure 1 and Figure 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 rotating axis of the first rotating shaft 412 is parallel to the rotating axis of the first rotating member 20. The first slider 414 is arranged at one 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 rotating 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 manner between the first push rod 413 and the first rotating member 20 may refer to the previous description and will not be elaborated herein. The length of the first push rod 413 is greater than the distance between the rotating axis of the first rotating shaft 412 and the rotating 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 be linked 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, can reduce the rotational torque, reduce the rotational resistance, and is beneficial to extending the service life of the rotating shaft.

[0046] Please refer to Figure 1 and Figure 10, Further, the second linkage 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 with the first rotating shaft 412. The second slider 424 is arranged at one 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 manner between the second push rod 423 and the second rotating member 30 can refer to the previous description and will not be elaborated 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 be linked with the first linkage 41 to drive the first rotating member 20 to rotate synchronously. Since the second linkage 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, can reduce the rotational torque, reduce the rotational resistance, and is beneficial 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. The first rotating shaft 412 and the second rotating shaft 422 may be linked by meshing. Both the first rotating shaft 412 and the second rotating shaft 422 are micro-rotating shafts. The size of the first rotating shaft 412 is smaller than that of the first rotating part 21, and the size of the second rotating shaft 422 is smaller than that of the second rotating part 31. Thus, the first rotating shaft 412 and the second rotating shaft 422 occupy a smaller layout space compared to the first rotating part 21 and the second rotating part 31. The first push rod 413 and the second push rod 423 are both of long-arm structures and are connected to the back sides of the first baffle 22 and the second baffle 32, occupying a small internal space of the rotating shaft base 10. Thus, the overall size of the linkage assembly 40 is small, suitable for being arranged in the small-sized rotating shaft base 10, which is conducive to realizing the miniaturization of the rotating shaft mechanism. By driving the first rotating shaft 412 and the second rotating shaft 422 to rotate synchronously through the long-arm-shaped first push rod 413 and the second push rod 423 respectively, the synchronous rotation torque of the first rotating member 20 and the second rotating member 30 is maintained at a relatively small level. Additionally, in this embodiment, the first push rod 413 and the second push rod 423 can meet the transmission requirements with a large spacing, without the need to set up a complex multi-gear transmission structure. The structure is simple, and the cumulative backlash error is small, which can meet the high-precision transmission requirements.

[0049] Please refer to Figure 11 and Figure 12 , further, the rotating shaft base 10 is provided with a receiving groove 13. Both the first rotating shaft 412 and the second rotating shaft 422 are received in the receiving groove 13. The plane formed by the rotation axes of the first rotating member 20 and 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 respectively rotatably connected to the first rotating member 20 and the second rotating member 30. 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 axes of the first rotating shaft 412 and the second rotating shaft 422 is located between the bottom surface 132 and the plane formed by the rotation axes of the first rotating member 20 and the second rotating member 30. Among them, the distance between the plane formed by the rotation axes of the first rotating shaft 412 and the second rotating shaft 422 and the bottom surface 132 is the first distance, and the distance between the plane formed by the rotation axes of the first rotating member 20 and the second rotating member 30 and the bottom surface 132 is the second distance, and the first distance is less 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 the 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 the direction perpendicular to the bottom surface 132. Among them, the rotation axes of the first rotating shaft 412 and the second rotating shaft 422 are relatively close to the bottom surface 132, and the rotation axes of the first rotating member 20 and the second rotating member 30 are relatively far from the bottom surface 132. Thus, the first rotating shaft 412 and the first rotating member 20 form a rotating shaft misalignment structure with a height difference, and the second rotating shaft 422 and the second rotating member 30 form a rotating shaft misalignment structure with a height difference. When the first main body 51 and the second main body 52 respectively flip relative to the rotating shaft base 10, the first rotating member 20 and the first linkage member 41 can cooperate to meet the rotational damping requirements at different angles, realize the hovering of the first main body 51 at any angle, and ensure that the rotational damping of the first main body 51 changes smoothly during the rotation process; the second rotating member 30 and the second linkage member 42 can cooperate to meet the rotational damping requirements at different angles, realize the hovering of the second main body 52 at any angle, and ensure that the rotational damping of the second main body 52 changes smoothly during the rotation process.

[0052] Please refer to Figure 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 less 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, both the first rotating shaft 412 and the second rotating shaft 422 are micro rotating shafts, the size of the first rotating shaft 412 is smaller than the size of the first rotating portion 21, and the size of the second rotating shaft 422 is smaller than the size of the second rotating portion 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 less than the distance between the rotation axis of the first rotating member 20 and the rotation axis of the second rotating member 30. Thus, the first rotating shaft 412 and the second rotating shaft 422 occupy a smaller layout space compared with the first rotating portion 21 and the second rotating portion 31. The first push rod 413 and the second push rod 423 are both long-arm structures and are connected to the back sides of the first baffle 22 and the second baffle 32, occupying a small internal space of the rotating shaft base 10. Thus, the overall size of the linkage assembly 40 is small, which is suitable for being arranged in a small-sized rotating shaft base 10 and is beneficial to realizing the miniaturization of the rotating shaft mechanism. By driving the first rotating shaft 412 and the second rotating shaft 422 to rotate synchronously through the long-arm-shaped first push rod 413 and the second push rod 423 respectively, 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 this embodiment, the first push rod 413 and the second push rod 423 can meet the transmission requirements of a large distance, without the need to set up a complex multi-gear transmission structure, with a simple structure and a small cumulative backlash error, and can meet the high-precision transmission requirements.

[0053] Please refer to Figure 13 , Further, the relative direction of the second slider 424 and the first slider 414 is 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.

[0054] In this embodiment, both the first slider 414 and the second slider 424 are cylindrical. The first slider 414 is rotationally and slidably engaged with the first chute 223 of the first rotating member 20. The second slider 424 is rotationally and slidably engaged with the second chute 323 of the second rotating member 30. By the same length of the first push rod 413 and the second push rod 423, and the angle formed by the plane constituted 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 being equal to the angle formed by the plane constituted 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 between the second slider 424 and the first slider 414 can be parallel to the plane constituted by the rotation axes of the first rotating member 20 and the second rotating member 30. Since the first linkage 41 and the second linkage 42 are linked, 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 frictional force of the first slider 414 relative to the first rotating member 20 and the frictional force of the second slider 424 relative to the second rotating member 30 are at least partially cancelled out, achieving the torque balance during the rotation of the first rotating member 20 and the second rotating member 30. In other embodiments, the first slider 414 and the second slider 424 may also be provided in other shapes.

[0055] The sliding direction of the first slider 414 relative to the first rotating member 20 is perpendicular to the rotation axis direction of the first rotating member 20. Among them, the first baffle 22 is provided with a first chute 223, and the first baffle 22 is rotationally and slidably engaged with the first slider 414 through the first chute 223. The first chute 223 extends from the rotating end of the first baffle 22 towards the first connection end 222, and the extending direction of the first chute 223 is perpendicular to the rotation axis of the first rotating member 20. When the first baffle 22 rotates relative to the rotating shaft base 10 away from the second baffle 32, the first slider 414 slides towards the direction close to the first connection end 222; when the first baffle 22 rotates relative to the rotating shaft base 10 towards the second baffle 32, the first slider 414 slides towards the direction close to the first rotating end 221. The first slider 414 reciprocally slides in the first chute 223, and can generate a frictional force perpendicular to the axis direction on the first rotating member 20, which can meet the rotational damping requirements of the first rotating member 20 at multiple angles, thereby ensuring the rotation feel.

[0056] The sliding direction of the second slider 424 relative to the second rotating member 30 is perpendicular to the axis of rotation direction of the second rotating member 30. Wherein, the second baffle 32 is provided with a second chute 323, and the second baffle 32 is rotationally and slidably engaged with the second slider 424 through the second chute 323. The second chute 323 extends from the rotating end of the second baffle 32 towards the second connection end 322, and the extending direction of the second chute 323 is perpendicular to the axis of rotation of the second rotating member 30. When the first baffle 22 rotates relative to the rotating shaft base 10 away from the second baffle 32, the second slider 424 slides towards the direction close to the second connection end 322; when the first baffle 22 rotates relative to the rotating shaft base 10 towards the second baffle 32, the second slider 424 slides towards the direction close to the second rotating end 321. The second slider 424 reciprocally slides in the second chute 323, which can generate a frictional force perpendicular to the axis direction for the second rotating member 30, and can meet the rotational damping requirements of the second rotating member 30 at multiple angles, thereby ensuring the rotational feel.

[0057] Please refer to Figure 14 , further, the first rotating member 20 is provided with a first rotating portion 21, the first rotating portion 21 is rotatably connected to the rotating shaft base 10, the first rotating portion 21 and the first sliding portion 23 are arranged side by side in the axis direction of the rotation of the first linkage 41, and the first linkage 41 at least partially overlaps with the first sliding portion 23 and the first rotating portion 21.

[0058] In this embodiment, the first rotating member 20 is further provided with a first main body portion 24 fixedly connecting the first rotating portion 21 and the first sliding portion 23. The first main body portion 24 is in a flat plate shape. The first main body portion 24 is provided with two first side edges 241 arranged oppositely. Both of the two first side edges 241 are substantially perpendicular to the axis direction of the rotation of the first linkage 41. The first rotating portion 21 and the first sliding portion 23 are respectively adjacent to the two first side edges 241. The axis of rotation of the first rotating portion 21 is parallel to the axis of rotation of the first linkage 41. The first main body portion 24 and the first sliding portion 23 constitute the first baffle 22. A first chute 223 is formed between the first sliding portion 23 and the first main body portion 24. The first slider of the first linkage 41 is slidably engaged with the first chute 223.

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

[0060] Please refer to Figure 15 , further, 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 rotation axis direction of the second linkage 42, and the second linkage 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 second main body portion 34 is in a flat plate shape. The second main body portion 34 is provided with two second side edges 341 arranged oppositely. Both of the two second side edges 341 are substantially perpendicular to the rotation axis direction of the second linkage 42. The second rotating portion 31 and the second sliding portion 33 are respectively adjacent to the two second side edges 341. The rotation axis of the second rotating portion 31 is parallel to the rotation axis of the second linkage 42. The second main body portion 34 and the second sliding portion 33 form the second baffle 32. A second chute 323 is formed between the second sliding portion 33 and the second main body portion 34. The second slider of the second linkage 42 can be in sliding fit with the second chute 323.

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

[0063] Please refer to Figure 16 and Figure 17, Further, the rotating shaft base 10 is provided with a first end 17 and a second end 18 disposed opposite to the first end 17. The first rotating part 21 is located on a side of the first linkage 41 close to the first end 17, and the second rotating part 31 is located on a side of the second linkage 42 close to the second end 18. In a state where the first main body 51 and the second main body 52 are unfolded, at least a part of the first rotating part 21 and the second rotating part 31 overlap each other.

[0064] In this embodiment, the rotating shaft base 10 is in a long strip shape. The first end 17 and the second end 18 respectively form two ends of the rotating shaft base 10. Then, the relative direction between the first end 17 and the second end 18 is the length direction of the rotating shaft base 10. The first rotating part 21 and the second rotating part 31 are spaced apart in the length direction of the rotating shaft base 10. The first linkage 41 and the second linkage 42 are located between the first rotating part 21 and the second rotating part 31. At least a part of the first linkage 41 overlaps with the first rotating part 21, and at least a part of the second linkage 42 overlaps with the second rotating part 31. In a state where the first main body 51 and the second main body 52 are unfolded, at least a part of the first rotating part 21 and the second rotating part 31 overlap each other, that is, the first rotating part 21 and the second rotating part 31 form an interleaved structure, so that the distance between the rotation axes of the first rotating part 21 and the second rotating part 31 is reduced, and the layout space occupied by the rotating shaft base 10 is reduced. Moreover, the first linkage 41 and the second linkage 42 are located within the distance between the first rotating part 21 and the second rotating part 31, and there is no need to additionally increase the width dimension of the rotating shaft base 10 to provide layout space, which is beneficial to the miniaturization of the rotating shaft mechanism.

[0065] Please refer to Figure 16 and Figure 17 , Further, the first rotating part 21 is provided with a first connection structure 211 extending along an arc. The first rotating part 21 is rotationally connected to the rotating shaft base 10 through the first connection structure 211. The second rotating part 31 is provided with a second connection structure 311 extending along an arc. The second rotating part 31 is rotationally connected to the rotating shaft base 10 through the second connection structure 311. The distance between the rotation axes of the first rotating part 21 and the second rotating part 31 is less than the sum of the radius of the first connection structure and the radius of the second connection structure.

[0066] In this embodiment, the first rotating part 21 is in the shape of a semi-circular plate. The first rotating part 21 is provided with a first arc-shaped edge 212. The first arc-shaped edge 212 is a semi-circle. The first connecting structure 211 extends along a direction parallel to the first arc-shaped edge 212. The first connecting structure 211 can be an arc-shaped groove. Then, the first bracket 14 is provided with a first protruding structure 141, and the first protruding structure 141 is also an arc-shaped structure. The first protruding structure 141 is in sliding fit with the first connecting structure 211. Then, the first connecting structure can slide relative to the first protruding structure 141 along an arc, 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. Both the first connecting structure 211 and the first protruding structure 141 have relatively large radii, so that the rotation fitting area between the first rotating part 21 and the first bracket 14 is relatively large, which is beneficial to ensuring the stable rotation of the first rotating part 21 relative to the first bracket 14 and ensuring the shaft strength. In other embodiments, the first rotating part 21 can also be of other shapes, which are not limited herein. The first connecting structure 211 can be a protruding structure. Correspondingly, a groove structure that is in rotating fit with the first connecting structure 211 can be provided on the first bracket 14.

[0067] The second rotating part 31 is in the shape of a semi-circular plate. The second rotating part 31 is provided with a second arc-shaped edge 312. The second arc-shaped edge 312 is a semi-circle. The second connecting structure 311 extends along a direction parallel to the second arc-shaped edge 312. The second connecting structure 311 can be an arc-shaped groove. Then, the second bracket 15 is provided with a second protruding structure 151, and the second protruding structure 151 is also an arc-shaped structure. The second protruding structure 151 is in sliding fit with the second connecting structure 311. Then, the second connecting structure can slide relative to the second protruding structure 151 along an arc, so that the second rotating part 31 can rotate relative to the second bracket 15, and the rotation axis of the second rotating part 31 coincides with the center of the second connecting structure 311. Both the second connecting structure 311 and the second protruding structure 151 have relatively large radii, so that the rotation fitting area between the second rotating part 31 and the second bracket 15 is relatively large, which is beneficial to ensuring the stable rotation of the second rotating part 31 relative to the second bracket 15 and ensuring the shaft strength. In other embodiments, the second rotating part 31 can also be of other shapes, which are not limited herein. The second connecting structure 311 can be a protruding structure. Correspondingly, a groove structure that is in rotating fit with the second connecting structure 311 can be provided on the second bracket 15.

[0068] Since the radii of the first rotating part 21 and the second rotating part 31 are relatively large, in order to save the width dimension of the rotating 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 arranged at intervals on the rotating shaft base 10, and the rotation axes of the first rotating part 21 and the second rotating part 31 are both parallel to the length direction of the rotating shaft base 10, so that the rotation movements of the first rotating part 21 and the second rotating part 31 do not interfere with each other. Also, since the distance between the rotation axis of the first rotating part 21 and the rotation axis of the second rotating part 31 is less than the sum of the radius of the first connection structure and the radius of the second connection structure, the distance between the rotation axis of the first rotating part 21 and the rotation axis of the second rotating part 31 is further reduced. On the one hand, it is beneficial to save the layout space and compress the width dimension of the rotating 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 41, and reduce the distance between the rotation axis of the second rotating part 31 and the rotation axis of the second linkage 42, which is beneficial to reducing the rotation torque and improving the user experience.
