[0081] Figure 1 is a schematic structural diagram of a hinge assembly 100 according to an exemplary embodiment. Figure 2 is an exploded schematic diagram showing a lever 2, a magnetic component 3 and a limit component 4 according to an exemplary embodiment. Figure 3 FIG. 1 is a schematic diagram showing the structure of a hinge body 1 according to an exemplary embodiment. Figure 1-Figure 3As shown, the hinge assembly 100 may include a hinge body 1, a lever 2, a magnetic assembly 3, and a limit assembly 4. The hinge body 1 may be used to connect to the housing of an electronic device equipped with the hinge assembly 100, and the hinge body 1 may include a folded state and an unfolded state. The hinge body 1 may switch between the folded state and the unfolded state, wherein the folded state is a state folded 90° relative to the unfolded state; in some embodiments, the hinge body 1 may only be able to hover in the unfolded state and the folded state, and in other embodiments, the hinge body 1 may also be able to hover in any bending state between the unfolded state and the folded state, and the bending state may be a state bent 30°, 60°, or any other angle relative to the unfolded state, and the present disclosure does not limit this.

[0082] One end of the lever 2 can be slidably connected to the hinge body 1, and the other end of the lever 2 can be slidably connected to the magnetic component 3 along a first direction. The magnetic component 3 can be connected to the housing of the electronic device configured with the hinge assembly 100, that is, the magnetic component 3 and the hinge body 1 can be relatively fixed through the housing of the electronic device. When the lever 2 slides relative to the hinge body 1, it can also slide relative to the magnetic component 3. When the hinge body 1 switches to an unfolded state or a folded state, one end of the lever 2 can slide relative to the hinge body 1 along the first direction, and the other end can slide relative to the magnetic component 3 along the first direction. The first direction is the length direction of the lever 2, that is, Figure 1 and Figure 2 For example, in some embodiments, when the hinge body 1 switches to the unfolded state, one end of the lever 2 can move along the Figure 2 The other end of the lever 2 can slide relative to the hinge body 1 from the upper left to the lower right. Figure 2 The hinge body 1 is folded and one end of the lever 2 can slide relative to the magnetic component 3 from the upper left to the lower right to move away from the magnetic component 3; when the hinge body 1 is switched to the folded state, one end of the lever 2 can slide along the Figure 2 The other end of the lever 2 can slide relative to the hinge body 1 from the lower right to the upper left. Figure 2 The lever 2 slides relative to the magnetic component 3 from the lower right to the upper left to approach the magnetic component 3. In other embodiments, when the hinge body 1 switches to the unfolded state, one end of the lever 2 can move along the Figure 2 The other end of the lever 2 can slide relative to the hinge body 1 from the lower right to the upper left. Figure 2 The hinge body 1 is folded and one end of the lever 2 can slide relative to the magnetic component 3 from the lower right to the upper left to approach the magnetic component 3; when the hinge body 1 is switched to the folded state, one end of the lever 2 can slide along the Figure 2 The other end of the lever 2 can slide relative to the hinge body 1 from the upper left to the lower right. Figure 2The sliding connection between the lever 2 and the hinge body 1 and the sliding connection between the lever 2 and the magnetic assembly 3 can be achieved by matching the slide groove with the guide rail.

[0083] The position limiting assembly 4 may include a locked state and an unlocked state. When the position limiting assembly 4 is in the locked state, a portion of the position limiting assembly 4 may be located between two opposing surfaces of the lever 2 and the magnetic assembly 3; and when the position limiting assembly 4 is in the unlocked state, the position limiting assembly 4 may be moved out of the two opposing surfaces of the lever 2 and the magnetic assembly 3. When the hinge body 1 is switched to the folded state, the position limiting assembly 4 may be in the locked state, the lever 2 may press the position limiting assembly 4 and then press the magnetic assembly 3, so that the magnetic assembly 3 is maintained in the first position. When the position limiting assembly 4 is switched to the unlocked state in response to the operation instruction, the magnetic assembly 3 may move from the first position to the second position along the first direction toward the lever 2.

[0084] Based on this, the cooperation between the limit component 4 and the lever 2 can press the magnetic component 3 to keep it in the first position, which is conducive to the mutual attraction between the magnetic component 3 and the matching magnetic part to maintain the folded state of the hinge body 1, and the subsequent limit component 4 can switch to the unlocked state in response to the operation instruction, and the magnetic component 3 can switch to the second position to release the mutual attraction force. Since when the hinge component 100 is in the folded state, the flexible screen of the electronic device equipped with the hinge component 100 is also in the folded state, when the magnetic component 3 is switched to the second position, in the absence of attraction, the flexible screen can release the internal stress to return to the flattened state, thereby driving the hinge component 100 to return to the unfolded state, realizing the automatic unfolding of the hinge component 100 and the automatic unfolding of the electronic device. Under the trend of lightweight development, there is no need for users to manually unfold the foldable electronic device, thereby improving the user experience.

[0085] The magnetic assembly 3 may include a magnet bracket 31 and a first elastic member 32. The magnet bracket 31 may be slidably connected to the lever 2 along a first direction. One end of the first elastic member 32 may be connected to the magnet bracket 31, and the other end may be used for fixing, for example, to the housing of the electronic device equipped with the hinge assembly 100. Figure 4-Figure 7As shown, when the hinge body 1 is in the folded state, the first elastic member 32 is compressed, and when the limit assembly 4 switches to the unlocked state in response to the operation instruction, the limit assembly 4 moves out of the two relative surfaces between the lever 2 and the magnet to provide a space gap for the first elastic member 32 to restore its deformation, thereby providing a force to the magnet bracket 31, so that the magnet bracket 31 moves, so that the magnetic assembly 3 as a whole can be switched from the first position to the second position, so that the magnetic assembly 3 and the matching magnetic member no longer attract each other, and the hinge assembly 100 can be automatically unfolded by using the internal force of the flexible screen of the electronic device. Among them, the first elastic member 32 may include a compression spring.

[0086] Still Figure 4-Figure 7 As shown, the magnetic component 3 may include a first magnetic component 33, and the first magnetic component 33 may be arranged on the magnetic bracket 31; the hinge component 100 may include a second magnetic component 5; when the magnetic component 3 is in the first position, as shown in FIG. Figure 8 As shown, the first magnetic member 33 and the second magnetic member 5 attract each other along a second direction perpendicular to the first direction; when the magnetic component 3 is in the second position, as shown Fig. 9 The first magnetic member 33 and the second magnetic member 5 are shown to repel each other. When the magnetic component 3 is in the second position, the mutual repulsion between the first magnetic member 33 and the second magnetic member 5 can generate a repulsive force perpendicular to the first direction, which can provide a force for the hinge component 100 to be restored to the unfolded state. In some other embodiments, when the magnetic component 3 is in the second position, the force between the first magnetic member 33 and the second magnetic member 5 can be zero. At this time, the hinge component 100 can be restored to the unfolded state by the internal force of the flexible screen of the electronic device configured with the hinge component 100, and the electronic device can be automatically unfolded. The first magnetic component 3 can be located in the device body on one side of the hinge component 100, and the second magnetic component 3 can be located in the device body on the other side of the hinge component 100.

[0087] like Fig.10 As shown, the limiting assembly 4 may include a limiting member 41 and a driving member 42. The driving member 42 may be fixed to the magnet bracket 31. The limiting member 41 may be connected to the driving member 42. Under the driving action of the driving member 42, the limiting member 41 may be driven to move along the second direction, that is, the limiting member 41 may move along the second direction. Fig.10The second direction is perpendicular to the first direction (the direction indicated by the arrow A). Based on this, when the hinge body 1 is in the folded state, at least a portion of the limiter 41 can be located between the two relative surfaces of the lever 2 and the magnet bracket 31, and the limiter assembly 4 is in a locked state. The driving member 42 can act on the limiter 41 in response to the operation instruction, so that the limiter 41 moves out of the two relative surfaces of the lever 2 and the magnet bracket 31, and a gap is formed between the lever 2 and the magnet. The first elastic member 32 resets and pushes the magnet bracket 31, so that the magnetic assembly 3 moves from the first position to the second position along the first direction toward the lever 2, and the mutual attraction between the first magnetic member 33 and the second magnetic member 5 is released, so that the hinge body 1 can automatically switch to the unfolded state, and the electronic device equipped with the hinge assembly 100 automatically unfolds.

[0088] Among them, the driving member 42 may include an output shaft, and the output shaft and the limit member 41 may be threadedly connected, so that the limit member 41 can be driven to reciprocate in the second direction by the rotation of the output shaft; in another embodiment, the driving member 42 may include memory metal, and the limit member 41 can be driven by the electrical stretching and contraction of the memory metal. In some other embodiments, the driving member 42 may include an electromagnet.

[0089] The limiting assembly 4 may also include a second elastic member 43, which is arranged along the second direction, and one end of the second elastic member 43 is connected to the magnet bracket 31, and the other end is connected to the limiting member 41; when the driving member 42 responds to the operation instruction, the limiting member 41 moves along the second direction and compresses the second elastic member 43, and the limiting assembly 4 switches to an unlocked state; at the same time, under the action of the first elastic member 32, the limiting member 41, the second elastic member 43 and the driving member 42 move with the magnet bracket 31, and the lever 2 can limit the limiting member 41 in the second direction, and the second elastic member 43 remains in a compressed state. When the lever 2 slides along the first direction away from the magnet bracket 31 to release the limit on the limiting member 41, the second elastic member 43 can be reset, and the limiting member 41 is reset under the action of the second elastic member 43, and the limiting assembly 4 switches to a locked state, and the limiting member 41 can be located between two opposing surfaces of the lever 2 and the magnet bracket 31.

[0090] The connection between the limit assembly 4 and the magnet bracket 31, and the connection between the lever 2 and the magnet bracket 31, will be specifically described as follows: the magnet bracket 31 may include a main body 311, a first extension 312 and a second extension 313, the first extension 312 and the second extension 313 are both connected to the main body 311, and the first extension 312 and the second extension 313 are both formed by extending outward from the edge of the main body 311 parallel to the second direction, and in the second direction, a spacing distance is set between the first extension 313. The first magnetic member 33 of the magnetic assembly 3 can be set on the main body 311, for example, the main body 311 may include a mounting groove, one or more first magnetic members 33 can be arranged in the mounting groove, and the multiple first magnetic members 33 can be arranged side by side or in multiple rows, and can be specifically designed adaptively according to the shape of the mounting groove, and the present disclosure does not limit this.

[0091] The first extension part 312 may include a recessed groove 3121 recessed along the first direction, and the end of the lever 2 away from the hinge body 1 may extend into the recessed groove 3121 to be slidably connected with the magnet bracket 31, and the driving member 42 of the limiting assembly 4 may be connected with the second extension part 313, and the limiting member 41 extends toward the first extension part 312 along the second direction and extends into the recessed groove 3121, and the limiting member 41 may be slidably connected with the first extension part 312, so that the movement of the limiting member 41 is limited when the subsequent driving member 42 or the second elastic member 43 acts on the limiting member 41. For example, the limiting member 41 may include a guide groove, and the first extension part 312 may include a guide block disposed in the recessed groove 3121, and the limiting member 41 is limited by the sliding connection between the guide block and the guide groove; or the movement of the limiting member 41 may be limited by the cooperation of the slide groove and the guide rail, and the present disclosure is not limited to this. The shapes of the first extension portion 312 and the second extension portion 313 can be adaptively designed.

[0092] The above embodiments can be applied to the technical solution that when the hinge body 1 switches to the unfolded state, the lever 2 is away from the magnetic component 3, and when the hinge body 1 switches to the folded state, the lever 2 is close to the magnetic component 3, and can also be applied to the technical solution that when the hinge body 1 switches to the unfolded state, the lever 2 is close to the magnetic component 3, and when the hinge body 1 switches to the folded state, the lever 2 is away from the magnetic component 3. The following is an exemplary description of the automatic reset in the above two structures:

[0093] For the technical solution that when the hinge body 1 switches to the unfolded state, the lever 2 is away from the magnetic component 3, and when the hinge body 1 switches to the folded state, the lever 2 is close to the magnetic component 3, as shown in FIG. Figure 4-Figure 7As shown, during the switching process of the hinge body 1 to the folding state, the lever 2 can approach the magnetic component 3 from right to left. During the continuous folding process, one end of the lever 2 can press the magnetic bracket 31 through the limiting component 4 to compress the first elastic member 32. The magnetic component 3 is in the first position and the first elastic member 32 is in a compressed state. Until the hinge body 1 is switched to the folded state, the relative position relationship of the magnetic component 3, the limiting component 4 and the lever 2 is shown in FIG. Figure 4 As shown, at this time Figure 8 As shown, the first magnetic member 33 and the second magnetic member 5 attract each other; Figure 5 As shown, at the moment when the limit assembly 4 responds to the operation command, the limit assembly 4 can be moved out of the two opposite surfaces of the magnet bracket 31 and the lever 2, thereby providing a space gap, and the first elastic member 32 restores the deformation and switches to Figure 6 In the state shown, the magnet bracket 31 moves along the Figure 6 The magnetic component 3 switches to the second position. Fig. 9 As shown, the first magnetic member 33 and the second magnetic member 5 repel each other. Under the action of the repulsive force and the flexible screen, the hinge body 1 switches to the unfolded state, and the electronic device automatically unfolds; and as the hinge body 1 continues to unfold, the lever 2 can move away from the magnetic component 3, that is, the lever 2 can move along the Figure 7 The movement from left to right in the middle can remove the limit of the limit assembly 4 in the second direction by the lever 2, and the second elastic member 43 can restore the deformation. Under the action of the second elastic member 43, the limit assembly 41 can move from bottom to top, and the limit assembly 4 can be restored to the locked state, so that when the hinge assembly 100 is subsequently switched to the folded state, the lever 2 presses the magnetic assembly 3 by pressing the limit assembly 4. It should be noted that the directions from top to bottom and from left to right are all explained with reference to the directions in the corresponding figures, and the movement direction can be determined according to the corresponding position relationship in the actual spatial structure.

[0094] For the technical solution that when the hinge body 1 switches to the unfolded state, the lever 2 is close to the magnetic component 3, and when the hinge body 1 switches to the folded state, the lever 2 is away from the magnetic component 3, as shown in Figure 11-Figure 18 As shown, when the hinge body 1 is in the folded state, the relative position relationship between the lever 2, the limit assembly 4 and the magnetic assembly 3 is as shown in FIG. Fig.11 As shown, at this time, the limit assembly 4 is in a locked state, the lever 2 presses the limit member 41 and then presses the magnet bracket 31, and the first elastic member 32 is compressed. Figure 8 As shown, the first magnetic member 33 and the second magnetic member 5 attract each other; Fig.12As shown, at the moment when the driving member 42 responds to the operation command, the limiting member 41 moves out of the two opposite surfaces of the lever 2 and the magnet bracket 31, thereby providing a space gap, and under the action of the first elastic member 32, the magnet bracket 31 can be pushed along Figure 2 Slide from left to right and switch to Fig.13 In the state shown, the magnetic component 3 switches to the second position. Fig. 9 As shown, the first magnetic member 33 and the second magnetic member 5 repel each other. Under the action of the repulsive force and the flexible screen, the hinge body 1 switches to the unfolded state, and the electronic device automatically unfolds. As the hinge body 1 continues to unfold, the lever 2 can move closer to the magnet bracket 31, that is, the lever 2 can move along the direction shown in FIG. Fig.14 As shown in the right-to-left direction movement, the lever 2 continuously presses the first elastic member 32, and can continuously limit the limiting member 41 in the second direction, so that the second elastic member 43 is continuously compressed. Moreover, since the hinge body 1 has been unfolded to a certain angle at this time, the first magnetic member 33 and the second magnetic member 5 cannot attract each other, so the hinge body 1 can automatically switch to the unfolded state. At this time, the relative position relationship between the magnetic component 3, the limiting component 4 and the lever 2 is as shown in FIG. Fig.15 As shown. Fig.16 As shown, when the hinge body 1 is subjected to an external force and needs to be switched to the unfolded state, the lever 2 can move along the Fig.16 As shown in FIG. 1 , the first elastic member 32 moves away from the magnet support 31 from left to right, and gradually returns to its original position until the first elastic member 32 is in the state of being moved away from the magnet support 31 from left to right. Fig.17 As shown, when the first elastic member 32 is in a natural state and there is a certain gap between the lever 2 and the magnet bracket 31, the second elastic member 43 can restore the deformation and push the limit member 41 along the Fig.17 The limit assembly 4 switches to the locked state, and due to the extension of the limit member 41, as shown in FIG. Fig.18 As shown in FIG. 1 , the first elastic member 32 can be compressed, and as the hinge body 1 continues to fold, the lever 2 moves along the Fig.18 The first elastic member 32 recovers its deformation, and the magnet bracket 31 and the limit assembly 4 both move from right to left until they switch to Fig.11 As shown in the relative position relationship, the hinge body 1 switches to the folded state.

[0095] exist Figure 11-Figure 18 In the embodiment shown, the stopper 41 may include a tip 412 and a tail 411 connected to the tip 412. It is understood that in the first direction, the width of the tail 411 is greater than the width of the tip 412, and the tail 411 may be connected to the second elastic member 43. Based on this, since the tip 412 is relatively small in the first direction, Fig.17As long as a small gap is generated between the magnet support 31 and the lever 2, the tip 412 can be pushed into between the lever 2 and the magnet support 31 under the action of the second elastic member 43, and the tail 411 can be further inserted into between the lever 2 and the magnet support 31 to compress the first elastic member 32. Further, in order to improve the smoothness of the limiter 41 switching to the locked state, the tail 411 can include a first guide surface 4111 inclined along the direction from the tip 412 to the tail 411, and the end of the lever 2 away from the hinge body 1 can include a second guide surface 21. Through the cooperation of the first guide surface 4111 and the second guide surface 21, the smoothness of the tail 411 extending into between the magnet support 31 and the lever 2 can be improved, and the compression of the first elastic member 32 can be achieved.

Among them, when the hinge body 1 switches to the folded state, the first support member 12 and the second support member 13 can respectively rotate relative to the base body 11 and move in the direction away from the base body 11, and the end of the lever 2 that cooperates with the first support member 12 can slide relative to the first support member 12, and the other end of the lever 2 can slide relative to the magnet bracket 31 and the lever 2 is away from the magnet bracket 31; when the hinge body 1 switches to the unfolded state, the first support member 12 and the second support member 13 can respectively rotate relative to the base body 11 and move in the direction close to the base body 11, and the end of the lever 2 that cooperates with the first support member 12 can slide relative to the first support member 12, and the other end of the lever 2 can slide relative to the magnet bracket 31 and the lever 2 moves close to the magnet bracket 31, so as to release the limit on the limit assembly 4.

[0097] In order to realize the movement of the first support member 12 and the second support member 13 relative to the base 11, the hinge body 1 may further include a plurality of control rods 14, wherein one end of at least one control rod 14 is movably connected to the base 11, and the other end is rotationally connected to the first support member 12, wherein one end of at least one control rod 14 is movably connected to the base 11, and the other end is rotationally connected to the second support member 13. When the control rod 14 connected to the first support member 12 moves relative to the base 11, the first support member 12 can be driven to rotate relative to the base 11, and the first support member 12 can be moved closer to or away from the base 11, and when the control rod 14 connected to the second support member 13 moves relative to the base 11, the second support member 13 can be driven to rotate relative to the base 11, and the second support member 13 can be moved closer to or away from the base 11. In the embodiment provided in the present disclosure, the hinge body 1 includes four control rods 14, which are symmetrically arranged in pairs; in other embodiments, the hinge body 1 may also include two or three or other numbers of control rods 14, and the present disclosure does not limit this.

[0098] Specifically, the seat body 11 may include an arcuate track, and each control rod 14 may include an arcuate guide portion 141 and a rotating portion 142 connected to the arcuate guide portion 141, the rotating portion 142 being used to be rotatably connected to the first support member 12 or the second support member 13, and the arcuate guide portion 141 may cooperate with the arcuate track of the seat body 11, and when the arcuate guide portion 141 moves relative to the arcuate track of the seat body 11, the rotating portion 142 may be pushed to move along the length direction of the control rod 14, so that the rotating portion 142 of the control rod 14 connected to the first support member 12 may drive the first support member 12 to rotate relative to the seat body 11 while pushing the first support member 12 to move closer to or away from the seat body 11, and the rotating portion 142 of the control rod 14 connected to the second support member 13 may drive the second support member 13 to rotate relative to the seat body 11 while pushing the second support member 13 to move closer to or away from the seat body 11.

[0099] The seat body 11 may include a bracket 111 and a cover body 112 connected to the bracket 111, the bracket 111 may include an arcuate recessed portion 1111, and the cover body 112 may include an arcuate convex portion 1121. When the cover body 112 and the bracket 111 are assembled, the arcuate convex portion 1121 may extend into the arcuate recessed portion 1111 to form an arcuate track. The arcuate track is formed by assembling the bracket 111 and the cover body 112, which is conducive to the installation of the control rod 14. The arcuate recessed portion 1111 may be arranged in a semicircular shape, and the arcuate convex portion 1121 may also be arranged in a semicircular shape, but the radius of the arcuate convex portion 1121 is smaller than the radius of the arcuate recessed portion 1111, so that when the arcuate convex portion 1121 is matched with the arcuate recessed portion 1111, an arcuate track can be formed due to the difference in radius, and the arcuate guide portion 141 may be arranged in a semicircular shape to match the arcuate track. Of course, the arc-shaped convex portion 1121 and the arc-shaped concave portion 1111 are only taken as an example to be arranged in a semicircular shape. In other embodiments, other shapes are also possible, as long as the movable portion can generate a displacement change while rotating relative to the arc track.

[0100] In order to achieve mutual folding between the first support member 12 and the second support member 13, the hinge body 1 may also include a synchronization mechanism 15, which may include a first guide rod gear 151 and a second guide rod gear 152, the first guide rod gear 151 includes a first guide rod end 1511 and a first gear end 1512, the second guide rod gear 152 may include a second guide rod end 1521 and a second gear end 1522, the first gear end 1512 and the second gear end 1522 are directly meshed or indirectly meshed, and the first gear end 1512 and the second gear end 1522 are respectively rotatably connected to the base body 11, the first guide rod end 1511 is slidably connected to the first support member 12, and the second guide rod end 1521 is slidably connected to the second support member 13. Based on this, when the first support member 12 of the seat body 11 is rotated relative to the seat body 11 by an external force, it can drive the control pull rod 14 to rotate relative to the seat body 11, thereby making the first support member 12 move away from or close to the seat body 11. At the same time, due to the relative rotation between the seat body 11 and the first support member 12, the first gear end 1512 of the first guide rod gear 151 rotates synchronously, thereby driving the second gear end 1522 of the second guide rod gear 152 to rotate synchronously, thereby realizing the folding of the hinge body 1.

[0101] In some embodiments, the lever 2 can be directly connected to the seat body 11 in rotation, and at the same time connected to the first support member 12 and the magnet support 31 in a sliding manner along the first direction, so that when the first support member 12 rotates relative to the seat body 11 and moves away from or approaches the seat body 11, the lever 2 can also rotate relative to the seat body 11 and move closer to or away from the magnet support 31 in the first direction.

Compared with the solution of the rotational connection between the lever 2 and the seat body 11, it is beneficial to shorten the length of the lever 2 and improve the strength of the lever 2.

For example, in Fig. 20 In the figure, the gear set 153 includes two gears meshing with each other, the left gear meshes with the second gear end 1522, and the right gear meshes with the first gear end 1512, so as to realize power transmission, and through an even number of gears, it can be ensured that the first gear end 1512 and the second gear end 1522 both rotate toward the same side of the seat body 11.

[0106] Among them, when the hinge body 1 is in a folded state, the first shell and the second shell are arranged relative to each other, the flexible display panel is folded in half, and the first magnetic component 33 of the magnetic component 3 can attract the second magnetic component 5 arranged in the second shell; and when the limit component 4 switches to an unlocked state in response to an operation instruction, the magnetic component 3 moves from the first position along the first direction toward the lever 2 to the second position, the magnetic component 3 releases the attraction to the second magnetic component 5, and the flexible display panel unfolds under the action of the internal force, thereby pushing the hinge body 1 to automatically switch to the unfolded state, and the electronic device automatically unfolds, which solves the problem that users unfold electronic devices with one hand under the trend of lightweight electronic devices.
