[0076] Figure 1 is a schematic structural diagram of a hinge component 100 shown according to an exemplary embodiment. Figure 2 is Figure 1 a exploded schematic diagram of the hinge component 100. The hinge component 100 can include an unfolded state and a folded state. When the hinge component 100 switches between the unfolded state and the folded state, the electronic device configured with the hinge component 100 can be driven to perform corresponding state transformations. For example, when the hinge component 100 is in the unfolded state, the electronic device configured with the hinge component 100 is in a flat state, and when the hinge component 100 is in the folded state, the electronic device configured with the hinge component 100 is in a folded state. In this folded state, the flexible screen of the electronic device is correspondingly folded. It can be understood that when the flexible screen is bent, the bent area of the flexible screen needs to occupy a certain space for deformation, and the size of the space is closely related to the internal stress after the deformation of the flexible screen. Therefore, the coordination between the state switching of the hinge component 100 and the bending trajectory and posture of the flexible screen has become an important research object of foldable electronic devices.

[0077] Based on this, this disclosure provides a kind of as Figure 1 and Figure 2The hinge component 100 shown may include a rotating assembly 1, a first support member 2, and a second support member 3. The first support member 2 includes a first support surface, and the second support member 3 includes a second support surface. Both the first support surface and the second support surface can be used to support the flexible screen of the electronic device to improve the rigidity of the flexible screen. The rotating assembly 1 can be used to switch the state of the hinge component 100. For example, by rotating the rotating assembly 1, the hinge component 100 can be driven to switch to a folded state or an unfolded state; the first support member 2 and the rotating assembly 1 at least partially overlap in a first direction, and the first support member 2 and the rotating assembly 1 can be slidably connected along the first direction; the second support member 3 can be movably connected to the rotating assembly 1, so that when the rotating assembly 1 rotates, the second support member 3 can correspondingly move with a part of the structure of the rotating assembly 1, so that the hinge component 100 switches to an unfolded state or a folded state. Wherein, the first direction is the Figure 2 direction indicated by arrow A in the figure. For the entire hinge component 100, the first direction can be the thickness direction of the hinge component 100. The movable connection between the second support member 3 and the rotating assembly 1 can include a sliding connection or a rotating connection, and the specific design is based on the fact that the second support member 3 will not jam when the rotating assembly 1 rotates.

[0078] In Figures 3 - 5 it is schematically shown the relative positional relationship between the flexible screen and the first support member 2 and the second support member 3 when the hinge component 100 is in different states. Specifically, when the hinge component 100 is in the unfolded state as shown in Figure 3 the figure, the flexible screen is in a flat state. The first support surface of the first support member 2 and the second support surface of the second support member 3 are located in the same plane, and the first support surface and the second support surface can be arranged side by side in a second direction. At this time, the first support surface of the first support member 2 and the second support surface of the second support member 3 cooperate to support the flexible screen, avoiding the deformation of the flexible screen caused by the stepped arrangement of the first support surface and the second support surface, and at the same time, it is beneficial to improve the stiffness of the flexible screen and reduce the deformation of the flexible screen. Wherein, the second direction is perpendicular to the first direction. As shown in Figure 3 the figure, the second direction is the direction indicated by arrow B.

[0079] Figure 4 shows an intermediate state diagram when the hinge component 100 switches from the unfolded state to the folded state. As shown in Figure 4 the figure, when the hinge component 100 switches from the unfolded state to the folded state, the rotating assembly 1 can rotate along the axis. By rotating the rotating assembly 1, the first support member 2 can be driven to slide along the first direction towards the rotating assembly 1, and the second support member 3 rotates with a part connected to the rotating assembly 1 until the hinge component 100 switches to Figure 5The folded state shown. When the hinge member 100 is in the folded state, the first support surface of the first support member 2 and the second support surface of the second support member 3 form a first preset angle, such as Figure 5 the first support surface and the second support surface shown can form an angle α.

[0080] Since the first support member 2 slides along the first direction toward the rotating assembly 1 during the process of the hinge member 100 switching to the folded state, it is assumed that in the unfolded state, the axis of the first support member 2 and the rotating assembly 1 are spaced apart by a first distance in the first direction, and in the folded state, the axis of the first support member 2 and the rotating assembly 1 are spaced apart by a second distance in the first direction. Then, the first distance is greater than the second distance. Therefore, when the flexible screen bends as the hinge member 100 folds, due to the movement of the first support member 2 toward the rotating assembly 1, an avoidance space can be provided for the bending of the flexible screen, so that the flexible screen can be bent in a larger space, reducing the excessive deformation of the flexible screen caused by the cooperation of the first support member 2 and the second support member 3, which is beneficial to reducing the internal stress of the flexible screen; and when the hinge member 100 switches from the folded state to the unfolded state, the first support surface of the first support member 2 and the second support surface of the second support member 3 move toward the same plane, which is beneficial to supporting each position of the flexible screen after it is flattened, and is beneficial to avoiding the bending of the flexible screen. Among them, as Figure 5 shown, the first preset angle can be an acute angle, so that a larger avoidance space can be formed by the cooperation of the second support member 3 near the first support member 2 and the first support member 2, which is beneficial to reducing the internal stress of the flexible screen. Of course, only the first preset angle being an acute angle is described here. In other embodiments, the first preset angle may also include a right angle or an obtuse angle, and the present disclosure does not limit this.

[0081] As Figures 1 - 5 shown in the embodiment, the hinge member 100 includes two second support members 3. When the hinge member 100 is in the unfolded state, one of the second support members 3 is located on one side of the first support member 2, and the other support member is located on the opposite side of the first support member 2. Thus, the two second support members 3 can support the flexible screens on both sides of the first support member 2. Of course, in the embodiment provided by the present disclosure, only the hinge member 100 including two second support members 3 is taken as an example for illustration. In other embodiments, the hinge member 100 may also include three or more second support members 3. When the hinge member 100 is in the unfolded state, at least one second support member 3 is located on one side of the first support member 2, and at least one second support member 3 is located on the opposite side of the first support member 2. The specific number of the second support members 3 can be designed as needed, and the present disclosure does not limit this.

[0082] Similarly, in the embodiments provided in the present disclosure, the hinge member 100 is described by taking the example that the hinge member 100 includes a single first support member 2. In other embodiments, the hinge member 100 may also include two or more first support members 2, and the two or more first support members 2 may be arranged side by side along the axial direction of the rotating assembly 1, and each first support member 2 may be connected to one or more rotating assemblies 1. For example, in the embodiments provided in the present disclosure, the hinge member 100 may include two rotating assemblies 1. The first end of the first support member 2 arranged along the axial direction of the rotating assembly 1 is connected to one of the rotating assemblies 1, and the second end of the first support member 2 arranged along the axial direction of the rotating assembly 1 is connected to the other rotating assembly 1. Alternatively, in other embodiments, the hinge member 100 may also include a single rotating assembly 1, or the hinge member 100 may include three or more rotating assemblies 1, and the present disclosure does not limit this.

[0083] The following will take the hinge member 100 provided in the present disclosure as an example to describe in detail the structure included in the hinge member 100. It should be noted that in the following embodiments, when the hinge member 100 includes multiple identical structures, only one of them will be described, and others can be referred to accordingly, and the present disclosure will not repeat them.

[0084] As Figures 6 - 8 shown, the rotating assembly 1 may include a first fixing member 11, a first connecting rod 12, and a first movable member 13. Among them, the first movable member 13 may be disposed on one side of the first fixing member 11 and is movably connected to the second support member 3. The first movable member 13 may include a first fitting groove 131. The first fixing member 11 may be slidably connected to the first support member 2 in a first direction. When the hinge member 100 subsequently switches between the unfolded state and the folded state, the first support member 2 may move toward or away from the first fixing member 11. As Figure 9 shown, the first connecting rod 12 may include a first rotating shaft portion 121, a second rotating shaft portion 122, and a third rotating shaft portion 123. The axes of the first rotating shaft portion 121, the second rotating shaft portion 122, and the third rotating shaft portion 123 are parallel to each other. The first rotating shaft portion 121 may be movably connected to the first support member 2, so as to transmit the acting force when the first movable member 13 and the first fixing member 11 move relative to each other to the first support member 2 through the cooperation between the first rotating shaft portion 121 and the first support member 2, and drive the first support member 2 to slide in the first direction; the second rotating shaft portion 122 may be rotatably connected to the first fixing member 11, and the third rotating shaft portion 123 may be slidably connected to the first fitting groove 131. Subsequently, when the first movable member 13 moves, the first connecting rod 12 is driven to rotate based on the second rotating shaft portion 122 through the cooperation between the third rotating shaft portion 123 and the first fitting groove 131.

[0085] Therefore, when the hinge member 100 switches between the unfolded state and the folded state, the first movable member 13 rotates relative to the first fixed member 11. The first movable member 13 drives the second support member 3 to move relative to the first fixed member 11. Through the cooperation of the first fitting groove 131 and the third rotating shaft portion 123, the second rotating shaft portion 122 can be driven to rotate relative to the first fixed member 11. Furthermore, the first support member 2 is driven by the first rotating shaft portion 121 to slide relative to the rotating assembly 1 in the first direction, specifically, it can approach the first fixed member 11 or move away from the first fixed member 11 in the first direction. Based on this, through the cooperation of the first movable member 13 and the first link 12, the synchronous movement between the first support member 2 and the second support member 3 can be achieved, that is, while the first support member 2 slides relative to the first fixed member 11 in the first direction, the second support member 3 rotates relative to the first fixed member 11, which is beneficial to adapting to the deformation requirements in the thickness direction and on both sides when the flexible screen is bent.

[0086] In some embodiments, the first link 12 may include a first connecting portion 124 and a second connecting portion 125. One end of the first connecting portion 124 may be connected to the first rotating shaft portion 121, and the other end may be connected to the second rotating shaft portion 122. One end of the second connecting portion 125 may be connected to the second rotating shaft portion 122, and the other end may be connected to the third rotating shaft portion 123. The first connecting portion 124 and the second connecting portion 125 are located on both sides of the second rotating shaft portion 122, and a second preset angle may be formed between the first connecting portion 124 and the second connecting portion 125. The second preset angle is greater than 0° and less than 180°. In this way, the axes of the first rotating shaft portion 121, the second rotating shaft portion 122, and the third rotating shaft portion 123 are not in the same plane. For example Figure 9 As shown, the axes of the first rotating shaft portion 121, the second rotating shaft portion 122, and the third rotating shaft portion 123 are arranged in sequence in the direction from top to bottom, which is beneficial to adapting to the position requirements of the first support member 2. Of course, in still some other embodiments, the second preset angle may also be equal to 180°. At this time, the axes of the first rotating shaft portion 121, the second rotating shaft portion 122, and the third rotating shaft portion 123 are in the same plane. Among them, the first connecting portion 124 and the second connecting portion 125 may be provided in a rod-shaped structure.

[0087] In some other embodiments, such as Figure 8 and Figure 10As shown, the first fixing member 11 may include a third connecting portion 111 and a guiding groove 112 arranged along the first direction. The guiding groove 112 may be slidably connected to the first supporting member 2 along the first direction. The third connecting portion 111 may include a groove 1111 recessed inward from the edge and shaft holes 1112 arranged on both sides of the groove 1111. The second connecting portion 125 may partially extend into the groove 1111, and the second rotating shaft portion 122 may be rotatably connected to the shaft holes 1112 to realize the rotational connection between the first fixing member 11 and the second rotating shaft portion 122. Subsequently, when either the first connecting portion 124 or the second connecting portion 125 rotates relative to the third connecting portion 111, it can drive the other to rotate relative to the third connecting portion 111 in the same direction, realizing the synchronous movement between the first movable member 13 and the first supporting member 2. Of course, in the embodiments provided in the present disclosure, only the example where the third connecting portion 111 includes a groove 1111 and shaft holes 1112 is described. In fact, in other embodiments, the third connecting portion 111 may also be a single shaft hole, and the second rotating shaft portion 122 is locked by other locking members, and the present disclosure does not limit this.

[0088] Wherein, since the first link 12 rotates based on the second rotating shaft portion 122, the movement of the third rotating shaft portion 123 is actually an arc movement. Therefore, in order to prevent the rotation of the first link 12 from being blocked due to the restriction of the third rotating shaft portion 123 by the first supporting member 2. The first fitting groove 131 may include a sliding groove. Specifically, the first fitting groove 131 may be slidably connected to the first rotating shaft portion 121. When the hinge member 100 is in the unfolded state, the first rotating shaft portion 121 is located at the first position of the second fitting groove 24. When the hinge member 100 switches from the unfolded state to the folded state, the first rotating shaft portion 121 may slide in the first fitting groove 131 in the shape of a sliding groove until the hinge member 100 is in the folded state, and the first rotating shaft portion 121 is located at the second position of the second fitting groove 24. In the first direction, there is a height difference between the first position and the second position to adapt to the movement trajectory when the second rotating shaft portion 122 drives the first rotating shaft portion 121 to rotate. Specifically, in the embodiments provided in the present disclosure, as Figures 11 - 13 shown, when the hinge member 100 switches from the unfolded state to the folded state, the first link 12 rotates based on the second rotating shaft portion 122. The first connecting portion 124 of the first link 12 rotates clockwise, and the third rotating shaft portion 123 will move in a direction away from the first movable member 13 and closer to the first fixing member 11. Therefore, at this time, the first position is above the second position, and the first position is close to the first movable member 13.

[0089] In the above embodiment, the same rotating assembly 1 may include a plurality of first movable members 13 and a plurality of first connecting rods 12, and the plurality of first movable members 13 and the plurality of first connecting rods 12 may be connected one by one, and at least one of the plurality of first movable members 13 is located on one side of the first fixed member 11, and at least one is located on the other side opposite to the first fixed member 11, and the second rotating shaft portions 122 of the plurality of first connecting rods 12 may be connected to the same first fixed member 11, for example, they may be connected to different sides of the same first fixed member 11. The first rotating shaft portions 121 of the plurality of first connecting rods 12 may all be connected to the same first supporting member 2, and when the plurality of first connecting rods 12 are located on different sides of the first fixed member 11, the first fixed member 11 may include two guide grooves 112, and the two guide grooves 112 may be connected to the same first supporting member 2, so as to improve the stability of the first supporting member 2 when sliding along the first direction relative to the first fixed member 11, and reduce the probability of the first supporting member 2 tilting; of course, in other embodiments, the first rotating shaft portions 121 of the plurality of first connecting rods 12 may also be connected to different first supporting members 2, and the present disclosure is not limited to this.

[0090] In some other embodiments, Figure 10 As shown, the first support member 2 may include a first main body 21, a first extension portion 22 and a guide portion 23. The first main body 21 may be arranged in a plate-like structure, and a first support surface of the first support member 2 may be formed by the first main body 21. The first extension portion 22 and the guide portion 23 are both connected to the side of the first main body 21 that is away from the first support surface. The guide portion 23 may be slidably connected to the guide groove 112 of the first fixing member 11 along a first direction. The first extension portion 22 may include a second matching groove 24, and the second matching groove 24 may be movably connected to the first rotating shaft portion 121. On the one hand, this can prevent the third rotating shaft portion 123 of the first connecting rod 12 from being stuck due to the second matching groove 24 not adapting to the movement of the third rotating shaft portion 123 when the second rotating shaft portion 122 rotates. On the other hand, through the matching of the first rotating shaft portion 121 and the second matching groove 24, the first connecting rod 12 can transmit the force to the first support member 2, thereby realizing the reciprocating sliding between the guide portion 23 and the guide groove 112.

[0091] In the above embodiments, the rotating assembly 1 may further include a second fixing member 14 and a second movable member 15, wherein the second fixing member 14 and the first fixing member 11 are arranged side by side along a third direction, and the third direction is the same as the axis direction of the rotating assembly 1. Figure 8As shown by arrow C. The second movable member 15 is movably connected to the second fixed member 14. The second movable member 15 can be arranged side by side with the first movable member 13 in a third direction. The second movable member 15 can be directly or indirectly connected to the first movable member 13. For example, both the second movable member 15 and the first movable member 13 can be connected to the middle frame of the electronic device to achieve an indirect connection between the first movable member 13 and the second movable member 15, or the first movable member 13 and the second movable member 15 can be directly fixedly connected by welding, riveting or screwing. Specifically, it can be designed according to needs, and the present disclosure does not limit this.

[0092] Moreover, when the hinge member 100 is in the unfolded state, the second movable member 15 and the second fixed member 14 can be arranged side by side in a second direction. When the hinge member 100 is subjected to an external force and switches from the unfolded state to the folded state, the first movable member 13 can move relative to the first fixed member 11, and the second movable member 15 can move relative to the second fixed member 14. Until the hinge member 100 is in the folded state, a third preset angle can be formed between the second movable member 15 and the second fixed member 14, and a third preset angle can also be formed between the first movable member 13 and the first fixed member 11. For example, the second movable member 15 and the second fixed member 14 can be vertically arranged, and the first movable member 13 and the first fixed member 11 can also be vertically arranged.

[0093] Among them, in order to increase the volume of the space where the bent portion of the flexible screen is located and reduce the creases caused by the hinge member 100 to the flexible screen. When the hinge member 100 switches from the unfolded state to the folded state, the second movable member 15 can move away from the second fixed member 14 while rotating relative to the second fixed member 14; when the hinge member 100 switches from the folded state to the unfolded state, the second movable member 15 can move closer to the second fixed member 14 while rotating relative to the second fixed member 14. Therefore, the minimum distance between the second movable member 15 and the second fixed member 14 in the folded state is greater than the minimum distance between the second movable member 15 and the second fixed member 14 in the unfolded state. Based on this, it is beneficial to increase the volume of the space where the bent area of the flexible screen is located in the folded state, and it is beneficial to reduce the internal stress of the flexible screen and extend the service life of the flexible screen. Among them, the minimum distance between the second movable member 15 and the second fixed member 14 in the folded state and the minimum distance between the second movable member 15 and the second fixed member 14 in the unfolded state are both described based on the first direction.

[0094] Specifically, the second movable member 15 may include a second arc-shaped guide rail 151, and the second fixed member 14 may include a second arc-shaped guide groove 141, and the second arc-shaped guide groove 141 may cooperate with the second arc-shaped guide rail 151. When the hinge member 100 is in the unfolded state, the second movable member 15 is disposed close to the second fixed member 14. At this time, the mating area between the second arc-shaped guide rail 151 and the second arc-shaped guide groove 141 is relatively large. Subsequently, as the second movable member 15 rotates relative to the second fixed member 14 and the hinge member 100 switches to the folded state, the mating area between the second arc-shaped guide rail 151 and the second arc-shaped guide groove 141 gradually decreases, and the second movable member 15 gradually moves away from the second fixed member 14. Until the hinge member 100 switches to the folded state, the mating area between the second arc-shaped guide rail 151 and the second arc-shaped guide groove 141 is the smallest, and the distance between the second movable member 15 and the second fixed member 14 is the farthest. Thus, through the cooperation of the second arc-shaped guide rail 151 and the second arc-shaped guide groove 141, while enabling the rotation between the second movable member 15 and the second fixed member 14, relative sliding between the two can be achieved.

[0095] In this embodiment, as Figures 11 - 13 shown, since during the rotation of the second movable member 15 relative to the second fixed member 14, there is also a relative movement of the second movable member 15 moving away from or approaching the second fixed member 14. Therefore, in order to adapt to this relative movement and prevent the rotation assembly 1 from jamming, the first fitting groove 131 included in the first movable member 13 may be a slot. The first fitting groove 131 is disposed along the second direction when the hinge member 100 is in the unfolded state, and the opening of the first fitting groove 131 faces the first fixed member 11 along the second direction; and when the hinge member 100 is in the unfolded state, the third rotating shaft portion 123 of the first link 12 is located at the end of the first fitting groove 131 away from the first fixed member 11. When the hinge member 100 switches to the folded state, the first movable member 13 rotates relative to the first fixed member 11 and gradually moves away from the first fixed member 11. Therefore, the third rotating shaft portion 123 can slide within the first fitting groove 131 and move toward the end of the first fitting groove 131 close to the first fixed member 11. Until the hinge member 100 switches to the folded state, the third rotating shaft portion 123 is located at the end of the first fitting groove 131 close to the first fixed member 11.

[0096] Similarly, in order to adapt to the relative movement mode between the second movable member 15 and the second fixed member 14, the second support member 3 may include a second main body 31 and a second extension portion 32. The second extension portion 32 is connected to a side of the second support member 3 away from the second support surface and extends toward the first fixed member 11. The second extension portion 32 may include a third mating groove 34, and the third mating groove 34 is movably connected to the third rotating shaft portion 123. For example, in the embodiment provided in the present disclosure, the third rotating shaft portion 123 may be slidably connected to the third mating groove 34, that is, the third rotating shaft portion 123 may slide along the trajectory defined by the first mating groove 131 while passing through the third mating groove 34. When the hinge member 100 is in the unfolded state, the third rotating shaft portion 123 may be located at an end of the third mating groove 34 away from the first fixed member 11. When the hinge member 100 switches to the folded state, the first movable member 13 rotates relative to the first fixed member 11 and gradually moves away from the first fixed member 11. The third rotating shaft portion 123 gradually approaches the first fixed member 11 along the first mating groove 131. At the same time, the third rotating shaft portion 123 may also slide along the third mating groove 34 until the hinge member 100 switches to the folded state, and the third rotating shaft portion 123 is located at an end of the third mating groove 34 close to the first fixed member 11. The third mating groove 34 may be arranged in an arc shape, and the specific arc parameters are related to the relative movement parameters of the first movable member 13 and the first fixed member 11.

[0097] In some embodiments, in order to define the rotation trajectory of the second support member 3 relative to the first fixed member 11, the second support member 3 may further include a first arc-shaped guide rail 33 located at an edge of the second main body 31 away from the first support member 2. The first movable member 13 may include a first arc-shaped guide groove 132, and the first arc-shaped guide groove 132 cooperates with the first arc-shaped guide rail 33. Through the cooperation of the first arc-shaped guide groove 132 and the first arc-shaped guide rail 33, on the one hand, the second support member 3 can rotate relative to the first fixed member 11, and on the other hand, the second support member 3 can move gradually away from or close to the first fixed member 11. Specifically, when the hinge member 100 is in the unfolded state, the mating area between the first arc-shaped guide rail 33 and the first arc-shaped guide groove 132 is small, and the end of the first arc-shaped guide rail 33 is located at an end of the first arc-shaped guide groove 132 close to the first fixed member 11. As the hinge member 100 switches to the folded state, the first movable member 13 rotates relative to the first fixed member 11, and the third rotating shaft portion 123 of the first link 12 drives the second support member 3 to rotate. At this time, the first arc-shaped guide rail 33 will move along the first arc-shaped guide groove 132, and the mating area between the first arc-shaped guide rail 33 and the first arc-shaped guide groove 132 gradually increases until the hinge member 100 switches to the folded state, and the mating area between the first arc-shaped guide rail 33 and the first arc-shaped guide groove 132 is the largest. Among them, the first arc-shaped guide groove 132 included in the first movable member 13 may be located on a side of the first movable member 13 away from the first fixed member 11.

[0098] Further, the first movable member 13 includes a first portion, a second portion, and a third portion. The first portion protrudes from one side of the second portion and the third portion, and the second portion and the third portion are arranged side by side and spaced apart. The first engaging grooves 131 are provided on both the second portion and the third portion. The openings of the first engaging grooves 131 on the second portion and the third portion are oppositely arranged. The first engaging grooves 131 provided on the second portion and the third portion can both cooperate with the third rotating shaft portion 123 of the first link. The first arc-shaped guide groove 132 is provided on the protruding portion of the first portion, and two first arc-shaped guide grooves 132 can be provided on the opposite sides of the first portion.

[0099] It should be noted that, in the embodiments provided in the present disclosure, in order to adapt to the relative movement manner between the second fixing member 14 and the second movable member 15, both the first engaging groove 131 and the third engaging groove 34 are strip-shaped. In fact, in other embodiments, when there is only relative rotation between the second fixing member 14 and the second movable member 15, both the first engaging groove 131 and the third engaging groove 34 can be hole-shaped, that is, both the first engaging groove 131 and the third engaging groove 34 can be rotatably connected to the third rotating shaft portion 123.

[0100] In some embodiments, the hinge member 100 may include a plurality of second support members 3. When the hinge member 100 is in the unfolded state, at least one second support member 3 is located on one side of the first support member 2, and at least one second support member 3 is located on the other side of the first support member 2. Moreover, each second support member 3 can be connected to the third rotating shaft portion 123 of a corresponding first link 12. The second support surfaces of the plurality of second support members 3 can all be used to support the flexible screen. In the embodiments provided in the present disclosure, the rotating assembly 1 may further include a third movable member 16 and a transmission member 17. The third movable member 16 can be movably connected to the second fixing member 14, and when the hinge member 100 is in the unfolded state, the second fixing member 14 can be located between the third movable member 16 and the second movable member 15; the connection manner between the third movable member 16 and the second fixing member 14 can refer to the connection manner between the second movable member 15 and the second fixing member 14. The third movable member 16 can be arranged side by side with the first movable member 13 on the same side, and the third movable member 16 is directly or indirectly connected to the first movable member 13.

[0101] The transmission member 17 can connect the second movable member 15 and the third movable member 16. Through the transmission member 17, when one of the second movable member 15 and the third movable member 16 rotates relative to the second rotating member, the other can be driven to rotate synchronously relative to the second rotating member. Furthermore, through the cooperation between the second arc-shaped guide rail 151 on the third movable member 16 and the second arc-shaped guide groove 141 on the second fixed member 14, the third movable member 16 can move away from or close to the second fixed member 14 synchronously when rotating relative to the second rotating member. Based on this, the first movable member 13 on the same side as the third movable member 16 can rotate relative to the second fixed member 14 under the drive of the third movable member 16, thereby driving the second support member 3 on the same side to rotate relative to the second fixed member 14, and the second support member 3 on the other side can rotate relative to the second fixed member 14 synchronously. Among them, when the rotating assembly 1 includes the second movable member 15 and the third movable member 16, multiple groups of second arc-shaped guide grooves 141 can be provided on the second fixed member 14 to cooperate with the second arc-shaped guide rails 151 of the second movable member 15 and the second arc-shaped guide rails 151 of the third movable member 16 respectively.

[0102] Among them, the second movable member 15 and the third movable member 16 can be connected to different first movable members 13. For example, the second movable member 15 can be connected to the first movable member 13 on the same side as the second movable member 15, and the third movable member 16 can be connected to the first movable member 13 on the same side as the third movable member 16. The first movable members 13 at different positions on the first fixed member 11 can be movably connected to the same first fixed member 11, and the connection methods can all refer to the foregoing embodiments. The second movable member 15 and the third movable member 16 can respectively include meshing portions. For example, the second movable member 15 can include a first meshing portion 153, and the third movable member 16 can include a second meshing portion 161. The transmission member 17 can include a gear set. The first end gear of the gear set can mesh with the first meshing portion 153, and the second end gear can mesh with the second meshing portion 161. The axis of the gear set is the same as the axis of the rotating assembly 1. Based on this, the purpose of synchronous movement between the second movable member 15 and the third movable member 16 can be achieved through the gear set.

[0103] In order to reduce the volume of the second movable member 15 and further reduce the occupied space of the hinge component 100. The first meshing portion 153 can be arranged between the two second arc-shaped guide rails 151, and the two second arc-shaped guide rails 151 can be respectively connected to two second arc-shaped guide grooves 141 arranged oppositely on the second fixed member 14; similarly, the second meshing portion 161 can be located between the two second arc-shaped guide rails 151 on the third movable member 16. The gear set can include an even number of mutually meshing cylindrical gears, so as to ensure that one of the second movable members 15 rotates counterclockwise and the other rotates clockwise, so that the second support members 3 on both sides of the first support member 2 approach each other, driving the flexible screen to bend.

[0104] In the above embodiments, the synchronous movement of the second support members 3 located on both sides of the first support member 2 is taken as an example for illustration. In other embodiments, the second support members 3 located on both sides of the first support member 2 may also move independently. At this time, the second support members 3 on the same side may be connected to the same first support member 2 through the first link 12, and the second support members 3 on the other side may be connected to another first support member 2 through the first link 12; at this time, the third movable member 16 and the second movable member 15 may move independently of each other. The user may first bend one side of the hinge member 100 and then bend the other side of the hinge member 100 to realize the switching of the hinge member 100 from the unfolded state to the folded state; or, the user may first unfold one side of the hinge member 100 and then unfold the other side of the hinge member 100 to realize the switching of the hinge member 100 from the folded state to the unfolded state.

[0105] In each of the above embodiments, the second fixing member 14 may be provided in an integral structure, or, as in the embodiments provided in the present disclosure, the second fixing member 14 may include a first split member 143 and a second split member 144, the first split member 143 and the second split member 144 are oppositely arranged, and the transmission member 17 may be disposed between the first split member 143 and the second split member 144. For example, when the transmission member 17 includes a gear set, each gear included in the gear set may be rotatably connected to the first split member 143 and the second split member 144 respectively; the second movable member 15 may be movably connected to both the first split member 143 and the second split member 144 at the same time. For example, a second arc-shaped guide groove 141 is provided on the side of the first split member 143 facing the second split member 144, a second arc-shaped guide groove 141 is provided on the side of the second split member 144 facing the first split member 143, and the second arc-shaped guide rails 151 provided on both sides of the first movable member 13 may be respectively matched with the second arc-shaped guide groove 141 provided on the first split member 143 and the second arc-shaped guide groove 141 provided on the second split member 144. Of course, in order to improve the coaxiality when the second movable member 15 is connected between the first split member 143 and the second split member 144, the second movable member 15 may include a rotating shaft surrounded by the second arc-shaped guide rail 151, and shaft holes surrounded by the second arc-shaped guide groove 141 may be respectively provided on the first split member 143 and the second split member 144. Through the cooperation of the rotating shaft of the second movable member 15 and the shaft holes on the first split member 143 and the second split member 144, the coaxiality of the connection is ensured.

[0106] Further, to enhance the aesthetics of the hinge component 100, the hinge component 100 may further include a decorative cover 4. The decorative cover 4 is fixedly connected to the first fixing member 11 and the second fixing member 14 respectively, and the decorative cover 4 is stacked with the first support member 2. When the hinge component 100 is configured in the electronic device, the side of the decorative cover 4 facing away from the first fixing member 11 and the second fixing member 14 may be located on the outer surface of the electronic device to block the internal structure of the hinge component 100 and enhance the aesthetics of the electronic device.

[0107] In some embodiments, to limit the position of the hinge component 100 when it is switched to the unfolded state or the folded state, as Figure 14 and Figure 15 shown, the hinge component 100 may further include a locking assembly 5. The locking assembly 5 may include a locking member 51 and an elastic member 52. The second fixing member 14 may include a locking surface 142. The locking surface 142 is located on the side of the second fixing member 14 close to the second movable member 15. For example, the locking surface 142 may be provided on the side edge of the first split member 143 facing the second movable member 15 and the side edge of the second split member 144 facing the second movable member 15. The locking surface 142 may include a first limiting surface 1421 and a second limiting surface 1422. When the hinge component 100 is in the unfolded state, the elastic member 52 is compressed and the locking member 51 is pressed against the first limiting surface 1421. The first limiting surface 1421 may be a stepped surface, and the stepped surface can increase the resistance of the locking member 51 to slide over the first limiting surface 1421, reducing the probability of the hinge component 100 automatically switching to the folded state. Similarly, when the hinge component 100 is in the folded state, the elastic member 52 is compressed, and the elastic member 52 can press the locking member 51 against the second limiting surface 1422. The second limiting surface 1422 may also be a stepped surface, and the stepped surface can increase the resistance of the locking member 51 to slide over the second limiting surface 1422, reducing the probability of the hinge component 100 automatically switching to the unfolded state.

[0108] Among them, as Figure 14 and Figure 15As shown, the elastic member 52 may include a compression spring. The locking surface 142 includes a curved surface that smoothly transitions from the first limiting surface 1421 to the second limiting surface 1422. When the hinge member 100 is switched between the unfolded state and the folded state, the locking member 51 may be continuously pressed against the locking surface 142 by the elastic member 52, thereby increasing the feel of the user during the process of switching the hinge member 100. In some other embodiments, the locking surface 142 may also include two independent curved surfaces, where one independent curved surface forms the first limiting surface 1421 and the other independent curved surface forms the second limiting surface 1422. When the hinge member 100 is about to be switched to the unfolded state, the locking member 51 approaches the first limiting surface 1421 until the hinge member 100 is switched to the unfolded state, and the locking member 51 is limited by the first limiting surface 1421. When the hinge member 100 is about to be switched to the folded state, the locking member 51 approaches the second limiting surface 1422 until the hinge member 100 is switched to the folded state, and the locking member 51 is limited by the second limiting surface 1422. In still some other embodiments, the locking surface 142 may also include a flat surface, and the flat surface includes a first limiting surface 1421 and a second limiting surface 1422 that are arranged in a stepped manner, and can be specifically designed as required. The present disclosure does not limit this.

[0109] In the embodiments provided by the present disclosure, the second movable member 15 may further include a mounting groove 152. A part of the locking member 51 and the elastic member 52 may be disposed in the mounting groove 152. One end of the elastic member 52 may be connected to the inner wall of the mounting groove 152, and the other end may abut against the locking member 51, so as to achieve the purpose of the elastic member 52 pressing against the locking member 51. At the same time, the movement of the locking assembly 5 can be synchronized with the movement of the second movable member 15, so that when the hinge member 100 is unfolded, the locking member 51 abuts against the first limiting surface 1421, and when folded, the locking member 51 abuts against the second limiting surface 1422. Wherein, the length direction of the mounting groove 152 may be arranged along the second direction, and the mounting groove 152 is located at one end of the second movable member 15 away from the first engaging portion 153 and the second arc-shaped guide rail 151. Moreover, the mounting groove 152 may be disposed at the edge position of the second movable member 15 to adapt to the design concept that the locking surface 142 is disposed at the edge position in the third direction on the second fixing member 14 to make room for the transmission member 17 and the first engaging portion 153. Moreover, in order to improve the stability of locking the hinge member 100 in the unfolded state or the folded state, the same second movable member 15 may include a plurality of mounting grooves 152, and each mounting groove 152 may correspond to one locking assembly 5 installed thereon. Thus, through the cooperation of the plurality of locking assemblies 5 and the locking surface 142, the damping force can be increased and the stability can be improved. The locking members 51 of the plurality of locking assemblies 5 may abut against different locking surfaces 142 or the same locking surface 142, which can be specifically designed according to needs. Similarly, the locking assembly 5 may also be installed on the third movable member 16. For details, reference may be made to the foregoing embodiments, and details will not be repeated herein.

[0110] In this embodiment, the locking member 51 may include a mounting portion 511, a fourth connecting portion 512, and a locking portion 513. The fourth connecting portion 512 may include a first end face and a second end face which are oppositely arranged. The first end face is connected to the mounting portion 511, and the first end face may protrude from the circumferential edge of the mounting portion 511 in an installed manner. In other words, the radial dimension of the fourth connecting portion 512 is larger than the radial dimension of the mounting portion 511. The elastic member 52 may be sleeved on the mounting portion 511 and abut against the first end face. The elastic member 52, the mounting portion 511, and the fourth connecting portion 512 are all located in the mounting groove 152. The mounting portion 511, the fourth connecting portion 512, and the locking portion 513 are all in a rod-shaped or block-shaped structure. The locking portion 513 is connected to the second end face of the fourth connecting portion 512, and the locking portion 513 may at least partially extend out of the mounting groove 152 to abut against the locking surface 142. In order to install the locking member 51, a notch communicating with the mounting groove 152 is provided on one side close to the mounting groove 152, and the locking portion 513 is movably inserted at the notch. Wherein, the mounting portion 511, the fourth connecting portion 512, and the locking portion 513 may be integrally formed, or may be independently formed and then welded and fixed.
