The linkage mechanism 30 is configured to rotate synchronously around the first axis and the second axis to drive the first connecting member 21 to move around the first axis, and drive the second connecting member 22 to move around the second axis, so that the first connecting member 21 and the second connecting member 22 can switch between the first position and the second position. The distance of the first connecting member 21 compared to the first axis and the distance of the second connecting member 22 compared to the second axis are the same. In the first position, the first connecting member 21 and the second connecting member 22 meet the coplanar condition, and in the second position, a receiving space is formed between the first connecting member 21 and the second connecting member 22.
[0068] The base 10 is in a nearly rectangular parallelepiped shape. Along the length direction of the base 10 , the base 10 has a first end and a second end opposite to each other; along the width direction of the base 10 , the base 10 has a first side and a second side opposite to each other. The first side and the second side are two opposite sides of the base 10 .
[0069] The connection assembly 20 includes a first connection member 21 and a second connection member 22. The first connection member 21 and the second connection member 22 may both be in a nearly rectangular parallelepiped shape. The length of the first connection member 21 and the length of the second connection member 22 match the length of the base 10. The first connection member 21 is located on a first side of the base 10, and the second connection member 22 is located on a second side of the base 10. The first connection member 21 is used to connect to the first body of the electronic device, and the second connection member 22 is used to connect to the second body of the electronic device.
[0070] In some embodiments, the linkage mechanism 30 includes a first motion unit and a second motion unit that are transmission-connected. The first motion unit is connected to the first connecting member 21, and the first motion unit is rotationally connected to the base 10, and the first motion unit can rotate around the first axis; the second motion unit is connected to the second connecting member 22, and the second motion unit can rotate around the second axis. The axial direction of the first axis is parallel to the axial direction of the second axis, and the first axis and the second axis are spaced apart along the width direction of the base 10. The first motion unit rotates around the first axis, the second motion unit rotates around the second axis, and the first motion unit and the second motion unit can rotate synchronously. The structures of the first motion unit and the second motion unit are similar, and the structure and connection relationship of the second motion unit can refer to the first motion unit.
[0071] In some embodiments, the main body of the first motion unit is in the form of a plate, one end of the first motion unit is configured with a rotating portion, a first axial hole is provided on the base, the rotating portion is rotatably connected to the first axial hole, and the first motion unit can rotate around the first axis where the first axial hole is located. The other end of the first motion unit can be connected to the first connecting member 21 by screwing, clamping, welding, etc. The first motion unit rotates around the first axis, and the first connecting member 21 rotates synchronously with the first motion unit around the first axis. A second axial hole is also provided on the base, and one end of the second motion unit is rotatably connected to the second axial hole.
[0072] In some embodiments, a rotating part is configured at one end of the first motion unit, a first axial hole is provided on the base, the rotating part is rotatably connected to the first axial hole, and the first motion unit can rotate around the first axis where the first axial hole is located. A slide groove is provided on the first connecting member 21, and the other end of the first motion unit can be slidably arranged in the slide groove. The first motion unit rotates around the first axis, and the first connecting member 21 can gradually approach or move away from the first axis during the process of synchronously rotating around the first axis with the first motion unit.
[0073] The first motion unit rotates around the first axis to drive the first connecting member 21 to move around the first axis, so that the first connecting member 21 can flip in the direction close to or away from the second connecting member 22. The second motion unit rotates around the second axis to drive the second connecting member 22 to move around the second axis, so that the second connecting member 22 can flip in the direction close to or away from the first connecting member 21. The first connecting member 21 and the second connecting member 22 can switch between the first position and the second position as the first motion unit and the second motion unit rotate. There is a gap between the first connecting member 21 and the base 10, the first connecting member 21 has a first side facing the base 10, the vertical distance between the first side and the first axis is defined as the first distance, and the distance from the first connecting member 21 to the first axis is the first distance. There is a gap between the second connecting member 22 and the base 10, the second connecting member 22 has a second side facing the base 20, the vertical distance between the second side and the second axis is defined as the second distance, and the distance from the second connecting member 22 to the second axis is the second distance. The distance between the first connecting member 21 and the first axis is the same as the distance between the second connecting member 22 and the second axis, that is, the first connecting member 21 and the second connecting member 22 always keep synchronous movement with the movement of the first moving unit and the second moving unit. Therefore, the force state of the first connecting member 21 and the second connecting member 22 can always be kept the same, and the position state of the first connecting member 21 and the second connecting member 22 relative to the base 10 can always be kept the same, and then in the first position posture, a stable supporting force can be provided, and in the second position posture, a stable accommodation space can be provided.
[0074] The first connecting member 21 has a top surface and a bottom surface opposite to each other along the thickness direction of the first connecting member 21; the second connecting member 22 has a top surface and a bottom surface opposite to each other along the thickness direction of the second connecting member 22.

[0075] like Figure 1 As shown, in the first position, the first connector 21 and the second connector 22 are in a parallel state, the angle formed between the first connector 21 and the second connector 22 is 180 degrees or close to 180 degrees, and the first connector 21 and the second connector 22 meet the coplanar condition, that is, the top surface of the first connector 21 and the top surface of the second connector 22 are located in the same plane. The hinge structure 100 is used in a folding screen mobile phone. In the first position, the folding screen mobile phone is in an unfolded posture, which meets the user's interaction needs on the inner screen.
[0076] like Figure 2As shown, in the second position, the first connector 21 and the second connector 22 are in a stacked state, that is, the angle formed between the first connector 21 and the second connector 22 is 0 degrees or close to 0 degrees, and a receiving space is formed between the first connector 21 and the second connector 22. The hinge structure 100 is used in a folding screen mobile phone. In the second position, the folding screen mobile phone is in a folded posture, and the receiving space is used to receive the bent section of the inner screen.
[0077] It is understandable that the first connecting member 21 and the second connecting member 22 can also be in a third position between the first position and the second position. In the third position, the angle formed between the first connecting member 21 and the second connecting member 22 can be 45 degrees, 90 degrees, 135 degrees, etc. The hinge structure 100 is used in a folding screen mobile phone. In the third position, the folding screen mobile phone has a hovering function, which can provide users with a variety of interaction modes to meet the diverse usage needs of users.
[0078] The linkage mechanism 30 not only connects the first connection member 21, the second connection member 22 and the base 10, but also synchronizes the movement of the first connection member 21 and the second connection member 22 through the synchronous rotation of the linkage mechanism 30 around the first axis and the second axis. On the premise of meeting the synchronous movement of the first connection member 21 and the second connection member 22, the number of parts of the rotating shaft structure 100 is effectively reduced. The reduction in the number of parts is conducive to reducing friction, and is also conducive to reducing manufacturing errors and assembly errors, which is conducive to the smoothness of the rotation of the rotating shaft structure 100.
[0079] In this embodiment, the linkage mechanism 30 is rotatably provided on the base 10, and the first connecting member 21 is connected to the second connecting member 22 through the linkage mechanism 30. The linkage mechanism 30 can rotate synchronously around the first axis and the second axis, so that the first connecting member 21 and the second connecting member 22 can move synchronously. On the premise of satisfying the synchronous movement of the first connecting member 21 and the second connecting member 22, the number of parts of the shaft structure 100 is effectively reduced, the friction force is reduced, and at the same time it is beneficial to reduce the process error, which is beneficial to the stability and smoothness of the rotation of the shaft structure 100.
[0080] In the embodiments of the present disclosure, Figure 1 , Figure 2 and Figure 3As shown, the linkage mechanism 30 includes a first connecting arm 31, a second connecting arm 32 and a transmission assembly 33. The first connecting arm 31 is provided at one side of the base 10, one end of the first connecting arm 31 is rotatably connected to the base 10, the other end of the first connecting arm 31 is connected to the first connecting member 21, and the first connecting arm 31 can rotate around the first axis so that the first connecting member 21 rotates around the first axis. The second connecting arm 32 is provided at the other side of the base 10, one end of the second connecting arm 32 is rotatably connected to the base 10, the other end of the second connecting arm 32 is connected to the second connecting member 22, and the second connecting arm 32 can rotate around the second axis so that the second connecting member 22 rotates around the second axis. The first connecting arm 31 is connected to the second connecting arm 32 through the transmission assembly 33, so that the first connecting arm 31 and the second connecting arm 32 rotate synchronously.
[0081] The first connecting arm 31 is used to realize the rotational connection between the first connecting member 21 and the base 10, and the second connecting arm 32 is used to realize the rotational connection between the second connecting member 22 and the base 10. The transmission assembly 33 is used to realize the synchronous rotation of the first connecting arm 31 and the second connecting arm 32, thereby realizing the synchronous rotation of the first connecting member 21 and the second connecting member 22. Along the width direction of the base 10, the base 10 has a first center plane, and the first connecting arm 31 and the second connecting arm 32 are symmetrically arranged about the first center plane. The number of the first connecting arm 31 and the second connecting arm 32 is set according to actual needs. For example, the number of the first connecting arm 31, the second connecting arm 32 and the transmission assembly 33 are all two. One first connecting arm 31, one second connecting arm 32 and one transmission assembly 33 are located at the first end of the base 10; another first connecting arm 31, another second connecting arm 32 and another transmission assembly 33 are located at the second end of the base 10.
[0082] In some embodiments, a receiving groove is formed on the base 10, and a portion of the first connecting arm 31, the transmission assembly 33, and a portion of the second connecting arm 32 are located at the receiving groove. For example, a U-shaped receiving groove is formed by the depression of the top surface of the base 10, and the groove width and groove depth of the receiving groove are set according to actual needs. The receiving groove has two opposite groove walls, and the two groove walls are defined as the first groove wall and the second groove wall. The first groove wall is provided with a first axial hole and a second axial hole, and the first axial hole and the second axial hole are arranged at intervals along the width direction of the base 10; the second groove wall is provided with a first axial groove corresponding to the first axial hole, and the second groove wall is also provided with a second axial groove corresponding to the second axial hole. That is, the first axial hole and the first axial groove are coaxially arranged, and the axis where the first axial hole and the first axial groove are located is the first axis; the second axial hole and the second axial groove are coaxially arranged, and the axis where the second axial hole and the second axial groove are located is the second axis. One end of the first connecting arm 31 is rotatably connected to the first shaft hole and the first shaft groove, and the other end of the first connecting arm 31 is connected to the first connecting member 21 by means of screw connection, clamping connection, welding, etc. One end of the second connecting arm 32 is rotatably connected to the second shaft hole and the second shaft groove, and the other end of the second connecting arm 32 is connected to the second connecting member 22 by means of screw connection, clamping connection, welding, etc. A first damping unit 51 and a second damping unit 52 are also provided at a position near the linkage mechanism 30 on the base 10, and the first connecting arm 31 is connected to the first damping unit 51 through the first shaft hole, and the second connecting arm 32 is connected to the second damping unit 52 through the second shaft hole. During the rotation of the first connecting arm 31 and the second connecting arm 32, the first damping unit 51 and the second damping unit 52 provide damping force.
[0083] The first connecting arm 31 is connected to the second connecting arm 32 through a transmission assembly 33. The transmission assembly 33 may be a gear transmission structure, a belt transmission structure, a chain transmission structure, etc. The first connecting arm 31 and the second connecting arm 32 are synchronously rotated through the transmission assembly 33. The first connecting arm 31, the transmission assembly 33, and the second connecting arm 32 are sequentially arranged along the width direction of the base 10, which effectively saves the space occupied by the linkage mechanism 30 in the length direction of the rotating shaft structure 100.
[0084] The first connecting arm 31 rotates around the first axis, the first connecting member 21 rotates around the first axis synchronously with the first connecting arm 31, the second connecting arm 32 rotates around the second axis, and the second connecting member 22 rotates around the second axis synchronously with the second connecting arm 32. During the process of the first connecting arm 31 and the second connecting arm 32 rotating toward or away from each other, the first connecting arm 31 and the second connecting arm 32 always keep rotating synchronously through the transmission of the transmission assembly 33.
[0085] In this embodiment, one end of the first connecting arm 31 is rotatably connected to the base 10, and the other end is connected to the first connecting member 21. One end of the second connecting arm 32 is rotatably connected to the base 10, and the other end is connected to the second connecting member 22. The first connecting arm 31, the second connecting arm 32 and the transmission assembly 33 are used to achieve synchronous rotation of the first connecting member 21 and the second connecting member 22. The overall structure is compact and occupies little space, which is conducive to the thinness of the rotating shaft structure 100.
[0086] In the embodiments of the present disclosure, Figure 1 , Figure 2 and Figure 3 As shown, the transmission assembly 33 includes a first driven gear 331 and a second driven gear 332 that are meshed and connected.

The first support member 41 and the first connecting member 21 are arranged opposite to each other, and the second support member 42 and the second connecting member 22 are arranged opposite to each other. The first support member 41 and the second support member 42 can both be plate-shaped bodies. The length dimension of the first support member 41 is adapted to the length dimension of the first connecting member 21.

The first side of the first support member 41 is hinged to the first connecting member 21, and the second side of the first support member 41 is rotatably connected or slidably connected to the base 10. The first connecting arm 31 rotates around the first axis, driving the first connecting member 21 and the first support member 41 to rotate synchronously.

That is, when switching from the first position to the second position, the angle of rotation of the first connecting member 21 and the second connecting member 22 is 90 degrees, and the angle of rotation of the first support member 41 and the second supporting member 42 is greater than 90 degrees. The first support member 41 and the second supporting member 42 are located in the accommodation space formed between the first connecting member 21 and the second connecting member 22. The first support member 41 and the second supporting member 42 are used to support the bending section of the display screen.
[0113] In this embodiment, the rotation of the first connecting arm 31 drives the first connecting member 21 and the first supporting member 41 to rotate synchronously, and the rotation of the second connecting arm 32 drives the second connecting member 22 and the second supporting member 42 to rotate synchronously, which can ensure the synchronization of the movement of the first supporting member 41 and the second supporting member 42 and realize the supporting function at the same time.
[0114] In the embodiments of the present disclosure, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a first guide member 11 is provided on one side of the base 10 close to the first connecting member 21, and a second guide member 12 is provided on one side of the base 10 close to the second connecting member 22. A first guide groove 4111 is provided at the end of the second side of the first support member 41, the first guide member 11 penetrates the first guide groove 4111, and the first support member 41 rotates around the axis of the first guide member 11. A second guide groove 4211 is provided at the end of the second side of the second support member 42, the second guide member 12 penetrates the second guide groove 4211, and the second support member 42 rotates around the axis of the second guide member 12. When the first connecting member 21 and the second connecting member 22 are rotated to be perpendicular to the base 10, a gradually changing accommodation space is formed between the opposing surfaces of the first support member 41 and the second support member 42.
[0115] The first guide member 11 and the second guide member 12 are spaced apart along the width direction of the base 10 . The first guide member 11 and the second guide member 12 may both be columnar bodies, and the axial directions of the first guide member 11 and the second guide member 12 are parallel to the axial directions of the first axis and the second axis.
[0116] The end of the second side of the first support member 41 is bent and extended to form a first extension portion 411. The first extension portion 411 is provided with a first guide groove 4111. The first guide groove 4111 is a long strip-shaped guide groove. The first guide member 11 is provided with the first guide groove 4111 to realize the movable connection between the first support member 41 and the base 10. When the first support member 41 rotates with the first connecting member 21, the first support member 41 rotates around the axis of the first guide member 11.
[0117] The end of the second side of the second support member 42 is bent and extended to form a second extension portion 421. The second extension portion 421 is provided with a second guide groove 4211. The second guide groove 4211 is a long strip-shaped guide groove. The second guide member 12 is provided with the second guide groove 4211 to realize the movable connection between the second support member 42 and the base 10. When the second support member 42 rotates with the second connecting member 22, the second support member 42 rotates around the axis of the second guide member 12.
[0118] like Figure 7 As shown, when the first connecting member 21 and the second connecting member 22 are rotated to be perpendicular to the base 10, the first supporting member 41 rotates at an angle greater than 90 degrees, and the second supporting member 42 rotates at an angle greater than 90 degrees, thereby forming a gradient accommodating space between the opposite surfaces of the first supporting member 41 and the second supporting member 42. The gradient accommodating space is suitable for accommodating the bent section of the display screen.
[0119] The hinge structure 100 is used in a folding screen electronic device, which is conducive to the thinning and lightness of the electronic device after being folded, and the gradient accommodating space can effectively reduce the creases in the bending section of the display screen, thereby improving the service life of the display screen.
[0120] In this embodiment, the second side of the first support member 41 is movably connected to the base 10 through the cooperation of the first guide member 11 and the first guide groove 4111, and the second side of the second support member 42 is movably connected to the base 10 through the cooperation of the second guide member 12 and the second guide groove 4211, so that in the second position, a gradient accommodating space is formed between the opposite surfaces of the first support member 41 and the second support member 42, which is suitable for accommodating the bending section of the display screen.
[0121] In the embodiments of the present disclosure, Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a first connection portion 412 is provided on a first side of the first support member 41, a second connection portion 212 is provided on the first connection member 21, and the first connection portion 412 and the second connection portion 212 are hinged. A third connection portion 422 is provided on a first side of the second support member 42, a fourth connection portion 222 is provided on the second connection member 22, and the third connection portion 422 and the fourth connection portion 222 are hinged.

[0122] In some embodiments, a first connecting portion 412 is provided on the first side of the first support member 41, the number of the first connecting portions 412 is two, and the first connecting portion 412 is provided with a first through hole. A second connecting portion 212 is convexly formed on the top surface of the first connecting member 21, and the second connecting portion 212 is provided with a second through hole, and the first through hole and the second through hole are adapted to each other. The second connecting portion 212 is sandwiched between the two first connecting portions 412, and after the pin shaft passes through the first through hole and the second through hole, the cotter pin is inserted to realize the hinge connection between the first connecting portion 412 and the second connecting portion 212. The hinge structure formed by the first connecting portion 412 and the second connecting portion 212 enables the first support member 41 and the first connecting member 21 to rotate relative to each other.
[0123] In some embodiments, a third connecting portion 422 is provided on the first side of the second support member 42, the number of the third connecting portions 422 is two, and the third connecting portion 422 is provided with a third through hole. A fourth connecting portion 222 is convexly formed on the top surface of the second connecting member 22, and the fourth connecting portion 222 is provided with a fourth through hole, and the third through hole and the fourth through hole are adapted. The fourth connecting portion 222 is sandwiched between the two third connecting portions 422, and after the pin shaft passes through the third through hole and the fourth through hole, the cotter pin is inserted to realize the hinge connection between the third connecting portion 422 and the fourth connecting portion 222. The hinge structure formed by the third connecting portion 422 and the fourth connecting portion 222 enables the second support member 42 and the second connecting member 22 to rotate relative to each other.
[0124] In the first position, the axis of the first guide member 11 and the axis of the second connection portion 212 are staggered along the height direction of the base 10, that is, the axis of the second connection portion 212 is higher than the axis of the first guide member 11. The height direction of the base 10 is consistent with the thickness direction of the base 10. The axis of the second guide member 12 and the axis of the fourth connection portion 222 are staggered along the height direction of the base 10, that is, the axis of the fourth connection portion 222 is higher than the axis of the second guide member 12.
[0125] Thus, through the relative rotation between the first connection part 412 and the second connection part 212, and the misalignment of the first guide member 11 and the second connection part 212, the rotation angle of the first support member 41 is greater than the rotation angle of the first connection member 21. Through the relative rotation between the third connection part 422 and the fourth connection part 222, and the misalignment of the second guide member 12 and the fourth connection part 222, the rotation angle of the second support member 42 is greater than the rotation angle of the second connection member 22.
[0126] In this embodiment, through the hinge structure and the staggered setting of the guide member and the hinge structure, the support member and the connecting member can achieve different rotation angles of movement during the switching process between the first position and the second position. The structure is simple and easy to implement.
