[0064] like Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a rotating shaft mechanism, which may include a base 100, a first support component 200, and a limiting mechanism 300.

[0065] The first support component 200 is rotatably connected to the base 100, allowing the first support component 200 and the base 100 to switch between a first relative position and a second relative position. The first support surface 201 can be used to support flexible components such as flexible screens. Because the first support component 200 and the base 100 are rotatably connected, the first support component 200 and the base 100 can form different support structures in the first relative position and the second relative position, in order to meet different support requirements (such as planar support and curved surface support).

[0066] The limiting mechanism 300 can connect the ends of the base 100 and the first support member 200 on the same side, so that the first support member 200 and the base 100 are limited in a first relative position and / or a second relative position. That is, when the first support member 200 and the base 100 are in the first relative position and / or the second relative position, the relative movement of the base 100 and the first support member 200 is restricted, so that the base 100 and the first support member 200 can maintain in that relative position (including the distance and angle between them, etc.), so as to achieve the stability of the base 100 and the first support member 200 in that relative position. Along the direction perpendicular to the rotation axis of the base 100 and the first support member 200, the projection area of ​​the limiting mechanism 300 is at least partially located outside the projection area of ​​the base 100 and / or the first support member 200. That is, the limiting mechanism 300 is located at the end of the base 100 and the first support member 200 on the same side and at least partially on the outside of the base 100 and the first support member 200. This facilitates the assembly of the limiting mechanism 300, avoids setting a limiting structure inside the base 100 and the first support member 200, simplifies the structure of the base 100 and the first support member 200, reduces the design difficulty, and avoids the limiting mechanism 300 occupying the space of the base 100 and the first support member 200 along the extension direction of the base 100, thereby reducing the size requirements of the base 100 and the first support member 200 along the extension direction of the base 100.

[0067] In some embodiments, the base 100 has a target support surface 101, which can be used to support flexible components such as flexible screens. The structure of the target support surface 101 can be determined according to the specific support effect. For example, the target support surface 101 can be an arc-shaped surface to provide arc-shaped support for the flexible component; it can also be a prism-shaped surface to provide multi-faceted support for the flexible component; or it can be a plane to provide planar support for the flexible component. It can also be a curved surface or a corrugated surface, etc.

[0068] The first support component 200 has a first support surface 201. The first support surface 201 can be used to support flexible components such as flexible screens. Because the first support component 200 is rotatably connected to the base 100, the first support component 200 and the base 100 can form different support structures in a first relative position and a second relative position. In different support structures, the relative position of the target support surface 101 and the first support surface 201 can be different, thereby meeting different support requirements. The first support surface 201 can be an arc-shaped surface, a prism surface, a plane, a curved surface, or a corrugated surface, etc.

[0069] The base 100 may include a base body 120 and a base support member 110, wherein the side of the base support member 110 facing away from the base body 120 is the target support surface 101. The base support member 110 may be formed by bending a substrate made of metal plate or other materials, such as... Figure 2 As shown, the base support 110 can be a "D" shaped structure, with its arc surface being the target support surface 101, and its plane connecting to the side of the base body 120 facing the base support 110 (which can be a plane). By processing the base body 120 and the base support 110 separately and then assembling them to form the base 100, the processing of the base 100 is facilitated, material costs are saved, and the structure of the target support surface 101 can be easily controlled by controlling the forming structure of the base support 110.

[0070] In some embodiments, the limiting effect can be achieved by restricting the movement direction of the first support member 200 relative to the base 100. During the process of switching from the second relative position to the first relative position, the first support member 200 can move relative to the base 100 along a first direction; wherein, the first direction is the rotation direction.

[0071] In the first relative position, the first support surface 201 and the target support surface 101 can form a first support structure for supporting the arc-shaped structure. The limiting mechanism 300 can restrict the movement of the first support component 200 relative to the base 100 along the first direction. That is, during the process of switching from the second relative position to the first relative position, the first support component 200 moves relative to the base 100 along the first direction. Upon reaching the first relative position, the limiting mechanism 300 restricts the movement of the first support component 200 relative to the base 100 along the first direction, so that the first support component 200 and the base 100 are restricted to the first relative position, thereby increasing the structural stability of the first support structure.

[0072] During the transition from the first relative position to the second relative position, the first support member 200 can move relative to the base 100 along a second direction; wherein the second direction can be a rotational direction, and is opposite to the first direction. Taking the first direction as the forward rotation direction as an example, the second direction can be the reverse rotation direction.

[0073] In the second relative position, the first support surface 201 and the target support surface 101 can form a second support structure for supporting the planar structure. The limiting mechanism 300 can restrict the movement of the first support member 200 relative to the base 100 along the second direction. That is, during the process of switching from the first relative position to the second relative position, the first support member 200 moves relative to the base 100 along the second direction (the direction opposite to the first direction). Upon reaching the second relative position, the limiting mechanism 300 restricts the movement of the first support member 200 relative to the base 100 along the second direction, so that the first support member 200 and the base 100 are restricted to the second relative position, thereby increasing the structural stability of the second support structure.

[0074] The limiting mechanism 300 can also apply a damping force to the first support member 200. When the first support member 200 moves relative to the base 100 to the first relative position or the second relative position, the damping force applied by the limiting mechanism 300 increases, thereby restricting the movement of the first support member 200 relative to the base 100, thus playing a limiting role.

[0075] In some embodiments, the limiting mechanism 300 includes a target trajectory structure 310 disposed at the end of the base 100, the target trajectory structure 310 having a first end 311 and a second end 312 facing away from each other.

[0076] The target trajectory structure 310 can be a straight trajectory, with the first end 311 and the second end 312 arranged along the direction of approaching and moving away from the target support surface 101.

[0077] A first connecting component 320 has a first connecting portion 3201 and a second connecting portion 3202. The first connecting portion 3201 moves along the target trajectory structure 310, and the second connecting portion 3202 is rotatably connected to the first support member 200. That is, during the switching between the first relative position and the second relative position, the first connecting portion 3201 moves along the arrangement direction of the first end 311 and the second end 312 of the target trajectory structure 310, and the second connecting portion 3202 rotates relative to the first support member 200.

[0078] During the transition to the first relative position, the first support member 200 can rotate relative to the base 100 by applying external force. This rotation causes the first connecting component 320 to move relative to the target trajectory structure 310. Specifically, the first support member 200 can move the first connecting portion 3201 to the first end 311 via the second connecting portion 3202, thus placing the first support member 200 and the base 100 in the first relative position. Since the target trajectory structure 310 has opposing first ends 311 and second ends 312, after the first support member 200 moves the first connecting portion 3201 to the first end 311 via the second connecting portion 3202, the first connecting portion 3201 cannot move beyond the position of the first end 311 and further away from the second end 312. This effectively limits the first connecting portion 3201 to the first end 311, preventing the first support member 200 from rotating further in the same direction, thus achieving the effect of being limited to the first relative position.

[0079] During the transition to the second relative position, the first support member 200 can be rotated relative to the base 100 by applying external force. This rotation causes the first connecting component 320 to move relative to the target trajectory structure 310. Specifically, the first support member 200, through the second connecting portion 3202, moves the first connecting portion 3201 to the second end 312, placing the first support member 200 and the base 100 in the second relative position. Since the target trajectory structure 310 has opposing first ends 311 and 312, after the first support member 200 moves the first connecting portion 3201 to the second end 312 via the second connecting portion 3202, the first connecting portion 3201 cannot exceed the position of the second end 312 and continue moving away from the first end 311. This effectively limits the first connecting portion 3201 to the second end 312, preventing the first support member 200 from continuing to rotate in the same direction, thus achieving the effect of limiting its position in the second relative position.

[0080] By controlling the positions of the first end 311 and the second end 312 of the target trajectory structure 310, the relative positions (first relative position and second relative position) between the first support component 200 and the base 100 can be controlled. Compared with a rotating shaft mechanism with a chain module, this avoids the accumulation of tolerances caused by sliding fit structures between multiple chains. This application controls the first relative position between the first support component 200 and the base 100 based on the position of the first end 311, and controls the second relative position between the first support component 200 and the base 100 based on the position of the second end 312. This effectively improves the accuracy of the first and second relative positions, avoids affecting the accuracy of the relative position between the first support component 200 and the base 100 due to excessive tolerances, and also avoids affecting the user experience of rotation due to excessive tolerances (such as smoothness and the probability of jamming).

[0081] In the rotating shaft mechanism with chain modules, in the support structure composed of multiple chain components, multiple chain components (at least three or more) connect the base and the support component. Adjacent chain components are limited by a set of sliding blocks. This results in the cumulative tolerance of the support component's rotation position relative to the base in multiple sets of sliding blocks, which can lead to a large tolerance and low limiting accuracy.

[0082] The component that determines the limiting position in this application is the target trajectory structure 310. By determining the positions of the first end 311 and the second end 312, the limiting accuracy at the first relative position and the second relative position can be achieved.

[0083] Taking the process of switching from the first relative position to the second relative position by rotating the first support component 200 relative to the base 100 by 90° as an example, in the first relative position, the orientation of the first support surface 201 forms a target angle with the orientation of the target support surface 101, so as to support the arc-shaped structure; in the second relative position, the orientation of the first support surface 201 is the same as that of the target support surface 101, so as to support the planar structure. Therefore, it is only necessary to move the first connecting part 3201 to the first end 311 so that the orientation of the first support surface 201 forms a target angle with the orientation of the target support surface 101, and move the first connecting part 3201 to the second end 312 so that the orientation of the first support surface 201 is the same as that of the target support surface 101. That is, the positioning accuracy of the first relative position and the second relative position is achieved by the structure of the target trajectory structure 310 (including the positions of the first end 311 and the second end 312).

[0084] In some embodiments, the first connecting assembly 320 may include a first base link 321 and a first support link 322 rotatably connected. The end of the first base link 321 away from the first support link 322 has a first connecting portion 3201, and the end of the first support link 322 away from the first base link 321 has a second connecting portion 3202. That is, the first connecting assembly 320 can be a link group. During the relative rotation of the first base link 321 and the first support link 322, the distance between the first connecting portion 3201 and the second connecting portion 3202 changes.

[0085] During the switching between the first relative position and the second relative position, the first base link 321 and the first support link 322 can rotate relative to each other, so that the second connecting part 3202 rotates relative to the first support member 200 and drives the first connecting part 3201 to move along the target trajectory structure 310.

[0086] Furthermore, in the first relative position, the first base connecting rod 321 and the first support connecting rod 322 form a first target angle, so that the first connecting part 3201 and the second connecting part 3202 have a first distance, and the first connecting part 3201 is confined to the first end 311; in the second relative position, the first base connecting rod 321 and the first support connecting rod 322 form a second target angle, so that the first connecting part 3201 and the second connecting part 3202 have a second distance, and the first connecting part 3201 is confined to the second end 312. By setting the first connecting assembly 320 as a connecting rod structure, the limiting function is achieved, and the processing and installation of the first connecting assembly 320 are further facilitated.

[0087] Wherein, the first support member 200 drives the first base link 321 to move through the first support link 322, so that when the first connecting part 3201 moves to the first end 311, the first support member 200 and the base 100 form a first angle.

[0088] The first support member 200 drives the first base link 321 to move through the first support link 322, so that when the first connecting part 3201 moves to the second end 312, the first support member 200 and the base 100 form a second angle.

[0089] The aforementioned angles can be referenced to the support directions of the first support member 200 and the base 100. At the first angle, the support direction of the first support member 200 and the support direction of the base 100 can be 180°; at the second angle, the support direction of the first support member 200 and the support direction of the base 100 can be 90° or other angles.

[0090] Alternatively, the first connecting component 320 can be configured with other structures, such as a telescopic rod structure, which can also achieve the same spacing between the first connecting part 3201 and the second connecting part 3202.

[0091] In some embodiments, the pivot mechanism may include a second support member 400 symmetrically disposed with respect to the base 100 relative to the first support member 200; the limiting mechanism 300 includes a second connecting member 330 symmetrically disposed with respect to the first connecting member 320, the second connecting member 330 having a fifth connecting portion (not shown, with...) Figure 1 The first connecting part 3201 overlaps with the fourth connecting part 3302, and the fifth connecting part moves along the target trajectory structure 310. The fourth connecting part 3302 is rotatably connected to the second support member 400.

[0092] The second connecting component 330 may have the same structure as the first connecting component 320. Specifically, the second connecting component 330 may include a second base connecting rod 331 (symmetrically arranged with respect to the base 100 relative to the first base connecting rod 321) and a second support connecting rod 332 (symmetrically arranged with respect to the base 100 relative to the first support connecting rod 322). The end of the second base connecting rod 331 away from the second support connecting rod 332 has a fifth connecting portion, and the end of the second support connecting rod 332 away from the second base connecting rod 331 has a fourth connecting portion 3302. The second support component 400 drives the fifth connecting portion to move to the first end 311 via the fourth connecting portion 3302, so that the second support component 400 and the base 100 are in a third relative position. That is, the third relative position is a symmetrical position between the first support component 200 and the base 100 in the first relative position, such that the second support component 400 and the first support component 200 are symmetrically arranged on both sides of the base 100. The second support member 400 drives the fifth connection member to move to the second end 312 through the fourth connection member 3302, so that the second support member 400 and the base 100 are in the fourth relative position, that is, the fourth relative position is the symmetrical position of the first support member 200 and the base 100 in the second relative position, so that the second support member 400 and the first support member 200 are symmetrically arranged on both sides of the base 100.

[0093] The base 100 has a base groove provided along the target trajectory structure 310. The base groove has a first groove end corresponding to the first end 311 and a second groove end corresponding to the second end 312. The displacement of the first connecting part 3201 is restricted by the inner walls of both ends of the straight groove, thereby restricting the movement of the first support connecting rod 322 by the first base connecting rod 321, so that the first support member 200 is limited to a first relative position relative to the base 100.

[0094] The first connection component 320 includes:

[0095] The first support link 322, one end of which is rotatably connected to the first support component 200;

[0096] The first base link 321 has one end slidingly and rotatingly engaged with the target trajectory structure 310, and the other end of the first support link 322 is rotatably connected to the other end of the first base link 321.

[0097] In the first relative position, the first support link 322 and the first base link 321 form a first target angle, and one end of the first base link 321 is in limiting contact with the first slide groove end (first end 311).

[0098] In the second relative position, the first support link 322 and the first base link 321 form a second target angle, and one end of the first base link 321 is in limiting contact with the second slide end (second end 312).

[0099] The second connection component 330 includes:

[0100] The second support link 332, one end of which is rotatably connected to the second support component 400;

[0101] The second base link 331 has one end slidingly and rotatingly engaged with the target trajectory structure 310, and the other end of the second support link 332 is rotatably connected to the other end of the second base link 331.

[0102] In the first relative position, the second support link 332 and the second base link 331 form a third target angle, and the third target angle and the first target angle satisfy the same conditions. One end of the second base link 331 is in limiting contact with the first slide groove end.

[0103] In the second relative position, the second support link 332 and the second base link 331 form a fourth target angle, which satisfies the same condition as the second target angle. One end of the second base link 331 is in limiting contact with the end of the second slide groove.

[0104] The first connecting part 3201 is rotatably connected to the base rotating shaft 301, which is slidably disposed in the base groove (target trajectory structure 310). The base groove can be a through groove, so that the first connecting component 320 and the second connecting component 330 are symmetrically arranged on both sides of the base groove. The fifth connecting part and the first connecting part 3201 can be connected to the base rotating shaft 301 to realize the synchronous movement of the fifth connecting part and the first connecting part 3201.

[0105] The base has a base side plate 130 and a base groove is a groove hole that passes through the base side plate 130; the first connecting component 320 and the second connecting component 330 are respectively located on both sides of the base side plate 130 and the base rotating shaft 301 is slidably disposed in the groove hole.

[0106] That is, the first base connecting rod 321 and the second base connecting rod 331 are located on both sides of the base side plate 130 along the thickness direction.

[0107] like Figure 1 As shown, the base groove (target trajectory structure 310) can be a straight groove arranged vertically. The second connecting part 3202 moves along a circular trajectory 001, the center of which is the rotation axis of the base 100 and the first support member 200. That is, the second connecting part 3202 is rotatably connected to the first support member 200 at a position other than the rotation axis. The second connecting part 3202 moves along the circular trajectory 001 by the rotation of the first support member 200 relative to the base 100. Because the first connecting part 3201 is restricted by the base groove, the distance between the first connecting part 3201 and the second connecting part 3202 changes. After the second connecting part 3202 moves upward a certain distance along the circular trajectory 001, it will drive the second connecting part 3202 of the first support link 322 to move upward to the second end 312.

[0108] like Figure 4 As shown, the first support member 200 has a first mating part 210 rotatably connected to the second connecting part 3202. The first mating part 210 and the base 100 are slidably mated through a first trajectory structure 102. The trajectory line of the first trajectory structure 102 is an arc trajectory line with the axis of the first rotating part rotatably connected to the first support member 200 and the base 100 as the center. The arc trajectory line can be the aforementioned circular trajectory 001.

[0109] Alternatively, the second support member 400 may have a second mating part that is rotatably connected to the fourth connecting part -3302. The second mating part and the base are slidably mated through a second trajectory structure. The trajectory line of the second trajectory structure is an arc trajectory line with the axis of the second rotating part as the center.

[0110] In some embodiments, the rotating shaft mechanism may include a target component 500, which is located on the side of the base 100 facing away from the target support surface 101; the first connecting assembly 320 has a third connecting portion 3203 connecting the target component 500. That is, the first connecting assembly 320 includes a first connecting portion 3201, a second connecting portion 3202, and a third connecting portion 3203, which are linked together. When the relative positions of the first connecting portion 3201 and the second connecting portion 3202 change, the third connecting portion 3203 can move, thereby driving the target component 500 to move.

[0111] During the process of switching to the first relative position, the first connecting part 3201 and the second connecting part 3202 move relative to each other, causing the third connecting part 3203 to move and drive the target component 500 to the first position. In this state, the distance between the first connecting part 3201 and the second connecting part 3202 can be a first distance.

[0112] During the transition to the second relative position, the first connecting portion 3201 and the second connecting portion 3202 move relative to each other, causing the third connecting portion 3203 to move and drive the target component 500 to the second position, so that the target component 500 can block a portion of the structure of the rotating shaft mechanism. That is, the target component 500 has at least the function of blocking a portion of the structure of the rotating shaft mechanism. The portion of the rotating shaft mechanism may include at least one of the following: at least a portion of the base 100, at least a portion of the first support component 200, and at least a portion of other components (such as the second support component 400). In this state, the distance between the first connecting portion 3201 and the second connecting portion 3202 can be a first distance.

[0113] The first position differs from the second position. In the second position, the target component 500 can block at least a portion of the base 100, thereby blocking the internal structure of the rotating shaft mechanism. Through the linkage of the first connecting part 3201, the second connecting part 3202, and the third connecting part 3203, the target component 500 is moved between the first relative position and the second relative position as the first support component 200 and the base 100 switch between them. This avoids the need for an additional sliding structure to move the target component 500, further simplifying the structure.

[0114] The number of target components 500 can be two, corresponding to the first connecting component 320 and the second connecting component 330 respectively.

[0115] When the first support member 200 and the base 100 are at a first angle, the first connecting part 3201 and the second connecting part 3202 move relative to each other so that the third connecting part 3203 moves and drives the target member 500 to the first position.

[0116] When the first support member 200 and the base 100 are at a second angle, the first connecting part 3201 and the second connecting part 3202 move relative to each other so that the third connecting part 3203 moves and drives the target member 500 to the second position.

[0117] In some embodiments, the first connecting assembly 320 may include a first base connecting rod 321, a first support connecting rod 322, a first slider connecting rod 323, and a first slider 324. The first slider connecting rod 323 is rotatably connected to a first rotating connection portion 3200 between the first base connecting rod 321 and the first support connecting rod 322. That is, the first base connecting rod 321, the first support connecting rod 322, and the first slider connecting rod 323 are rotatably connected through the first rotating connection portion 3200, forming a "Y"-shaped structure.

[0118] In some embodiments, the second connecting assembly 330 may include a second base connecting rod 331, a second support connecting rod 332, a second slider connecting rod 333, and a second slider 334. The second slider connecting rod 333 is rotatably connected to a second rotating connection portion 3300 between the second base connecting rod 331 and the second support connecting rod 332. That is, the second base connecting rod 331, the second support connecting rod 332, and the second slider connecting rod 333 are rotatably connected through the second rotating connection portion 3300, causing the first base connecting rod 321, the first support connecting rod 322, and the first slider connecting rod 323 to form a "Y"-shaped structure. Figure 2 and Figure 3 As shown, the first slider 324 can slide and rotate with the first slider connecting rod 323. The end of the first slider connecting rod 323 away from the first rotating connection portion 3200 is rotatably connected to the first slider 324 via a sliding shaft 325. The first slider 324 has a connecting rod groove 326 that slides with the sliding shaft 325, and the connecting rod groove 326 is disposed along the extending direction of the first slider 324. The first slider 324 has a third connecting portion 3203, that is, the first slider 324 is connected to the target component 500.

[0119] During the switching to the first relative position, the first base connecting rod 321 and the first support connecting rod 322 rotate relative to each other to the first target angle and drive the first rotating connecting part 3200 to move, so that the first rotating connecting part 3200 drives the first slider connecting rod 323 to move and causes the first slider 324 to slide and rotate relative to the first slider connecting rod 323, thereby driving the target component 500 to the first position. Figure 1 and Figure 3 As shown, in this embodiment, the target component 500 that reaches the first position extends along the orientation of the target support surface 101.

[0120] During the transition to the second relative position, the first base connecting rod 321 and the first support connecting rod 322 rotate relative to each other to the second target angle, causing the first rotating connecting part 3200 to move. This causes the first rotating connecting part 3200 to move the first slider connecting rod 323, and the first slider 324 to slide and rotate relative to the first slider connecting rod 323, thereby moving the target component 500 to the second position. Figure 1 and Figure 3 As shown, in this embodiment, the target component 500 that reaches the first position is perpendicular to the orientation of the target support surface 101, that is, the target component 500 has a surface with the same orientation as the target support surface 101.

[0121] like Figure 4 As shown, the first connecting component 320 can also include a first base link 321 and a first support link 322, and the target component 500 can be switched between a first position and a second position by setting other structures.

[0122] In some embodiments, the first support member 200 further has a second support surface 202, the structures of which are different from those of the first support surface 201 and the second support surface 202. The first support surface 201 can be curved, and the second support surface 202 can be planar. That is, the first support member 200 can be used to support different positions of the supported member. Taking the support of a flexible screen as an example, the first support surface 201 (and the target support surface 101) can be used to support the part of the flexible screen that needs to be bent, and the second support surface 202 can be used to support the part of the flexible screen that does not need to be bent. Through the above arrangement, the first support member 200, the base 100, and the second support member 400 form a three-segment structure to facilitate the support of the flexible screen. In the first relative position, the first support member 200 and the second support member 400 can form a 0° angle; in the second relative position, they can form a 180° angle.

[0123] In the first relative position, the orientation of the second support surface 202 forms a target angle with the orientation of the target support surface 101, such as 90°. In the second relative position, the second support surface 202 and the support position of the second support structure satisfy the coplanar condition.

[0124] In some embodiments, the target support surface 101 is an arc-shaped structure and is symmetrically arranged along a first centerline, which is the centerline of the base 100 along its extension direction; the position of the target support surface 101 corresponding to the first centerline is the first support position, and the connection position of the first support surface 201 and the second support surface 202 is the second support position of the first support structure; wherein, in the second relative position, the first support position and / or the second support position and the second support surface 202 satisfy the coplanar condition (including coplanar or substantially coplanar, etc.).

[0125] This invention also provides an electronic device, including a flexible screen, a first body, a second body, and a rotating mechanism. The rotating mechanism connects the first body and the second body to give the first body and the second body a first posture and a second posture. Specifically, by applying an external force, the relative positions of the first body and the second body change and rotate relative to the rotating mechanism, thereby switching between the first posture and the second posture.

[0126] In this embodiment, in the first posture, the first body and the second body can be folded relative to each other, and the included angle between them is 0°; in the second posture, the first body and the second body can be unfolded relative to each other, and the included angle between them is 180°.

[0127] The flexible screen has a first part, a second part, and a third part connecting the first part and the second part. The third part is a flexible bending part. The first part is connected to the first body, and the second part is connected to the second body.

[0128] The rotating mechanism may include a base 100, a first support component 200, and a limiting mechanism 300. The base 100 has a target support surface 101, which can be used to support flexible components such as flexible screens. The structure of the target support surface 101 can be determined according to the specific support effect. For example, the target support surface 101 can be an arc-shaped surface to provide arc-shaped support for the flexible component; it can also be a prism-shaped surface to provide multi-faceted support for the flexible component; or it can be a plane to provide planar support for the flexible component. It can also be a curved surface or a corrugated surface, etc.

[0129] The first support component 200 has a first support surface 201. The first support component 200 is rotatably connected to the base 100, allowing the first support component 200 and the base 100 to switch between a first relative position and a second relative position. The first support surface 201 can be used to support flexible components such as flexible screens. Because the first support component 200 is rotatably connected to the base 100, different support structures can be formed between the first and second relative positions to meet different support requirements (such as planar support and curved surface support). In different support structures, the relative position between the target support surface 101 and the first support surface 201 can be different. The first support surface 201 can be a curved surface, a prism surface, a plane, a curved surface, or a corrugated surface, etc.

[0130] The limiting mechanism 300 connects the base 100 and the first support member 200 on the same side, so that the first support member 200 and the base 100 are limited in a first relative position and / or a second relative position; along the direction perpendicular to the rotation axis of the base 100 and the first support member 200, the projection area of ​​the limiting mechanism 300 is at least partially located outside the projection area of ​​the base 100 and / or the first support member 200. That is, the limiting mechanism 300 is located at the end of the base 100 and the first support member 200 on the same side and at least partially on the outside of the base 100 and the first support member 200. This facilitates the assembly of the limiting mechanism 300, avoids setting a limiting structure inside the base 100 and the first support member 200, simplifies the structure of the base 100 and the first support member 200, reduces the design difficulty, and avoids the limiting mechanism 300 occupying the space of the base 100 and the first support member 200 along the extension direction of the base 100, thereby reducing the size requirements of the base 100 and the first support member 200 along the extension direction of the base 100.

[0131] The first support member 200 is rotatably connected to the base 100, allowing the first support member 200 and the base 100 to switch between a first relative position and a second relative position, and allowing the first body and the second body to switch between a first posture and a second posture. A limiting mechanism 300 connects the ends of the base 100 and the first support member 200 on the same side, allowing the limiting mechanism 300 to be located on one side of the first body and the second body. Alternatively, two limiting mechanisms 300 can be provided, each located on one side of the base 100 and the first support member 200, respectively, thus improving limiting stability.

[0132] In some embodiments, the pivot mechanism includes a target component 500, which is located on the side of the base 100 opposite to the target support surface 101 and is capable of at least partially obscuring the base 100.

[0133] When an electronic device is an outward-folding screen device (such as an outward-folding mobile phone or an outward-folding laptop), the first support component 200 and the base 100 are switched to the first relative position, the first body and the second body are stacked and the included angle between them is 0°, the target component 500 is located between the first body and the second body, and the flexible screen is at least partially located outside the first body and the second body.

[0134] That is, when the first body and the second body switch to the first posture, the first support member 200 and the base 100 can switch to the first relative position, and the target member 500 can be moved to the first position, so that the target member 500 is located between the first body and the second body. When the first body and the second body switch to the second posture, the first support member 200 and the base 100 can switch to the second relative position, and the target member 500 can be moved to the second position, so that the target member 500 can block part of the structure of the rotating shaft mechanism. The part of the structure of the rotating shaft mechanism may include at least one of at least a portion of the base 100, at least a portion of the first support member 200, and at least a portion of other components (such as the second support member 400).

[0135] Alternatively, the electronic device can be an inward-folding screen device (such as an inward-folding mobile phone or an inward-folding laptop). When the first supporting member 200 and the base 100 are switched to a first relative position, the first body and the second body are stacked with an angle of 0° between them. When the first supporting member 200 and the base 100 are switched to a second relative position, the first body and the second body are parallel to each other with an angle of 180° between them. The target member 500 can at least partially obscure the base 100 in both of these postures.

[0136] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0137] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
