The movable assembly 2 may include a sliding portion 21 disposed in a second direction, which is a direction indicated by an arrow B in fig. 1, and which is perpendicular to the first direction. The compensator 3 may include a first rotating portion 31, a first connecting portion 32 and a second connecting portion 33, and the center of the first rotating portion 31 is located outside the line connecting the center of the first connecting portion 32 and the center of the second connecting portion 33, it is understood that the compensator 3 may be arranged in a regular or irregular shape, and the compensator 3 may have three turning portions, which may be defined as the first rotating portion 31, the first connecting portion 32 and the second connecting portion 33, respectively, and the first rotating portion is offset from the line connecting the first connecting portion 32 and the second connecting portion 33 to form a subsequent rotation radius of the compensator 3.

In other drawings provided by the present disclosure, the first direction and the second direction in other drawings may be determined according to the orientation conversion of other drawings and fig. 1.

In this embodiment, drive the motion of compensation piece 3 through sliding part 21, and then promote the mounting 1 through the rotation of compensation piece 3 and be close to or keep away from the motion of movable part 2, for in the correlation technique, through setting the one end that the connecting piece that will connect mounting 1 and movable part 2 is connected with movable part 2 to the semicircle axle form, thereby utilize the centre of a circle position change of semicircle axle form when the connecting piece rotates to drive mounting 1 motion scheme, the drive mounting 1 in this disclosure is close to or keeps away from the technical scheme of movable part 2, can reduce the manufacturing degree of difficulty and the installation degree of difficulty.

In this embodiment, the first connecting portion 32 can be slidably connected with the sliding portion 21 along the first direction, and the second connecting portion 33 can be slidably connected with the fixing member 1 along the second direction. Based on this, when the hinge member 100 is switched to the folded state, the first rotating portion 31 of the compensating member 3 rotates relative to the movable assembly 2, the first connecting portion 32 can approach the fixed member 1 in the first direction, the second connecting portion 33 can push the fixed member 1 away from the movable assembly 2 in the first direction, and simultaneously the second connecting portion 33 can also slide relative to the fixed member 1 in the second direction to compensate the displacement of the second connecting portion 33 in the second direction caused by the rotation of the compensating member 3, so as to avoid the jamming; when the hinge member 100 is switched to the unfolded state, the first connecting portion 32 can be far away from the fixed member 1 along the first direction, and the second connecting portion 33 can pull the fixed member 1 to be close to the movable assembly 2 along the first direction, and at the same time, the second connecting portion 33 can also slide relative to the fixed member 1 along the second direction, so as to compensate the displacement of the second connecting portion 33 in the second direction caused by the rotation of the compensating member 3, and avoid the jamming. In the embodiment provided by the present disclosure, sliding grooves may be respectively disposed on the sliding portion 21 and the fixing member 1, the first connecting portion 32 and the second connecting portion 33 may respectively include sliding rods, and the sliding connection between the first connecting portion 32 and the sliding portion 21 and the sliding connection between the second connecting portion 33 and the fixing member 1 are realized through the cooperation of the sliding grooves and the sliding rods.

In the above embodiments, the movable assembly 2 may include the rotating member 22 and the transmission member 23, one end of the rotating member 22 may be slidably connected to the fixed member 1, and the rotating member 22 may be rotatably connected to the first rotating portion 31; the transmission member 23 may be connected between the sliding portion 21 and the rotating member 22, and the power generated when the rotating member 22 rotates may be transmitted to the sliding portion 21 through the transmission member 23, so as to push the sliding portion 21 to move in the second direction when the rotating member 22 rotates in the second direction. The rotating member 22 is configured to rotate around the second direction, and when the rotating member 22 rotates around the second direction, the one end slidably connected to the fixing member 1 may drive the fixing member 1 to rotate relative to the movable assembly 2, and the power transmission function of the transmission member 23 may drive the sliding portion 21 to move along the second direction, and the sliding portion 21 may drive the compensating member 3 to rotate relative to the rotating member 22, so that the compensating member 3 may drive the fixing member 1 to slide relative to the rotating member 22, and thus under the guiding function of the rotating member 22, the fixing member 1 may approach the movable assembly 2 when the hinge member 100 is switched towards the unfolding state, and may be far away from the movable assembly 2 when the hinge member 100 is switched towards the folding state.

The rotational connection between the rotating member 22 and the first rotating part 31 can be achieved in various ways, for example, in the embodiment provided by the present disclosure, the rotating member 22 can include the first shaft hole 221, the first rotating member can include the first rotating shaft 311, the axial direction of the first rotating shaft 311 is perpendicular to the first direction and the second direction, and the rotational connection between the rotating member 22 and the compensating member 3 is achieved through the cooperation of the first rotating shaft 311 and the first shaft hole 221; of course, in other embodiments, the rotating member 22 may include the first rotating shaft 311, and the first rotating part 31 includes the first shaft hole 221, which is not limited by the present disclosure.

Of course, since the rotating element 22 drives the fixed element 1 to rotate relative to the movable element 2, the second connecting portion 33 of the compensating element 3 also rotates with the fixed element 1, and therefore, in order to adapt to the rotation of the compensating element 3, when the rotating element 22 rotates around the second direction, the connecting portion between the sliding portion 21 and the compensating element 3 can also be driven to rotate around the second direction, so as to prevent the fixed element 1 from rotating relative to the movable element 2 due to the jamming of the compensating element 3. The rotation of the part of the sliding part 21 connected to the compensator 3 about the second direction can be understood as: when the sliding portion 21 includes only one part, the one part rotates around the second direction, and when the sliding portion 21 includes a plurality of parts that cooperate with each other, the part connected to the first connecting portion 32 of the compensating part 3 among the plurality of parts may rotate around the second direction, which may be specifically designed as needed, and the disclosure is not limited thereto.

Further, the movable assembly 2 may further include a base 24, for example, in some embodiments, the base 24 may include a base 241 and a cover 242 connected to the base 241, the base 241 and the cover 242 may be detachably connected or fixedly connected, and in other embodiments, the base 24 may also be an integrated base 24, which is not limited by the disclosure. As shown in fig. 7, the rotating member 22 may include a second rotating portion 222, a first engaging portion 223 and a second engaging portion 224, the second rotating portion 222 may be rotatably disposed relative to the base 24, the first engaging portion 223 and the second engaging portion 224 are respectively connected to the second rotating portion 222, the first engaging portion 223 and the second engaging portion 224 may extend from the second rotating portion 222 in a direction away from the base 24, the first engaging portion 223 may be slidably connected to the fixing member 1, the second engaging portion 224 may be rotatably connected to the first rotating portion 31 of the compensating member 3, that is, the second engaging portion 224 may be provided with a first rotating shaft 311 or a first shaft hole 221, so as to rotatably connect the first rotating portion 31 and the movable member 2. Based on this, the second rotating portion 222 can realize the rotation of the rotating member 22 relative to the base 24, so as to drive the first matching portion 223 and the second matching portion 224 to rotate relative to the base 24, respectively, and the first matching portion 223 can drive the fixing member 1 to rotate relative to the base 24, and the second matching portion 224 can drive the compensating member 3 to rotate relative to the base 24, thereby realizing the smoothness of the movement and avoiding the jamming.

The following will exemplify the mutual cooperation between the rotation member 22, the transmission member 23, and the sliding portion 21. The second rotating portion 222 includes a first tooth portion 2221, the transmission member 23 may include a gear 231 and a connecting rod 232, the gear 231 may be rotatably connected to the seat body 24, specifically, an axial direction of the gear 231 may be disposed along a third direction, the third direction is perpendicular to the first direction and the second direction, respectively, the gear 231 may be disposed in a space defined by the base 241 and the cover 242, and the gear 231 may be rotatably connected to the base 241. The gear 231 may include a second tooth portion 2311 engaged with the first tooth portion 2221, one end of the link 232 may be rotatably connected to the gear 231, and the connection position of the link 232 and the gear 231 is different from the center of the gear 231, the other end of the link 232 may be connected to the sliding portion 21, and the link 232 may also be disposed in a space enclosed by the base 241 and the cover 242, so as to improve the aesthetic property of the hinge member 100.

When the second rotating portion 222 rotates relative to the seat body 24, power can be transmitted to the gear 231 by the engagement between the first tooth portion 2221 and the second tooth portion 2311, and the drive gear 231 rotates in the third direction; since the connecting rod 232 is rotatably connected to the gear 231, when the gear 231 rotates, a force acting on the connecting rod 232 can be generated, one end of the connecting rod 232 connected to the gear 231 rotates along with the gear 231 in the third direction, one end of the connecting rod 232 connected to the sliding portion 21 can generate a force acting on the sliding portion 21, and the gear 231 can drive the sliding portion 21 to slide relative to the seat body 24 through the connecting rod 232. Based on this, the power generated when the second rotating portion 222 rotates can be transmitted to the compensating part 3 through the path of the second rotating portion 222, the gear 231, the connecting rod 232, the sliding portion 21 and the compensating part 3, the first rotating portion 31 of the compensating part 3 is driven to rotate relative to the second matching portion 224, no additional drive needs to be provided for the compensating part 3, and the situation that the fixing member 1 cannot timely avoid the flexible display panel due to the asynchronous movement of the second rotating portion 222 and the compensating part 3 is avoided.

The rotational connection between the first connection end 2321 and the gear 231 may be implemented by a guide rod and a circular hole which are parallel to the axial direction and the third direction, and the rotational connection between the second connection end 2323 and the sliding portion 21 may also be implemented by a guide rod and a circular hole which are parallel to the axial direction and the third direction, so as to avoid the locking and simultaneously implement the force transmission.

In other embodiments, regarding the rotational connection between the gear 231 and the seat body 24 and the rotational connection between the second rotating portion 222 and the seat body 24, the sliding connection between the sliding portion 21 and the seat body 24 can be realized by a separate structure; alternatively, as in the embodiment provided by the present disclosure, the gear 231 is connected to the seat body 24 in a rotating manner, the second rotating portion 222 is connected to the seat body 24 in a rotating manner, and the sliding connection between the sliding portion 21 and the seat body 24 can be realized by the same structure.

Based on this, when the second rotating portion 222 rotates relative to the base 241, the second rotating shaft 4 can be driven to rotate relative to the base 241 through the limiting action between the first plane 41 and the second plane, and the portion of the sliding portion 21 connected with the compensating part 3 can be driven to rotate relative to the seat body 24 through the second rotating shaft 4 due to the limiting action between the first plane 41 and the third plane; meanwhile, since the rotation of the second rotating portion 222 drives the gear 231 to rotate, the rotation of the gear 231 can drive the link 232 to generate displacement change in the second direction, and thus the sliding portion 21 can be driven to slide relative to the second rotating shaft 4 through the link 232. Of course, the transmission member 23 is only described as including the gear 231 and the connecting rod 232, and in other embodiments, the transmission member 23 may further include other components such as a guide rod, which is not limited in this disclosure. Therefore, on the one hand, the sliding part 21 can be driven to slide relative to the seat body 24 through the action of the rotating part 22 and the transmission part 23, and on the other hand, the part of the sliding part 21 connected with the compensating part 3 can be driven to rotate relative to the seat body 24 through the second rotating shaft 4, so that the compensating part 3 can drive the fixing part 1 to slide relative to the first matching part 223 while rotating relative to the seat body 24, and the synchronization and the fluency of the movement can be realized.

Based on the above-described respective embodiments, in some cases, the sliding portion 21 may include a single slider connected to the second connecting portion 33 of the compensator 3; in other cases, the sliding portion 21 may also include a plurality of sliding blocks, as in the embodiments provided in the present disclosure, the sliding portion 21 may include a first sliding part 211 and a second sliding part 212, the first sliding part 211 may be slidably disposed along the second direction, and the first sliding part 211 is connected to the transmission part 23, specifically, the first sliding part 211 may be slidably connected to the second rotating shaft 4 to achieve the sliding disposition of the first sliding part 211 relative to the seat body 24, and the first sliding part 211 may be rotatably connected to the connecting rod 232; the second sliding member 212 can be slidably disposed along the second direction, and particularly, the second sliding member 212 can be engaged with the second rotating shaft 4 to guide the sliding direction of the second sliding member 212 through the second rotating shaft 4, and the second sliding member 212 can also be slidably connected with the first connecting portion 32 of the compensating member 3.

In this embodiment, when the second rotating portion 222 of the rotating member 22 rotates relative to the seat body 24, the transmission member 23 can drive the first sliding member 211 to slide in the second direction under the guiding action of the second rotating shaft 4, and the first sliding member 211 can drive the second sliding member 212 to slide in the second direction under the guiding action of the second rotating shaft 4, so as to drive the first rotating portion 31 of the compensating member 3 to rotate relative to the second matching portion 224 of the rotating member 22 when the second sliding member 212 slides in the second direction; moreover, the third plane of the sliding portion 21 is disposed on the second sliding member 212, so that when the rotating member 22 rotates around the second direction, the second sliding member 212 can be driven to rotate around the second direction by the second rotating shaft 4, and the compensation member 3 can be driven to rotate relative to the seat body 24 by the rotation of the second sliding member 212, thereby avoiding the problem that the second connecting portion 33 of the compensation member 3 rotates along with the fixing member 1, and the first connecting portion 32 is fixed and is locked.

In some embodiments, the first sliding member 211 and the second sliding member 212 can be directly connected, for example, by a locking member such as a screw, so as to ensure that the second sliding member 212 can be driven to slide in the second direction when the first sliding member 211 slides in the second direction; in other embodiments, as shown in fig. 8, the second sliding part 212 may include a receiving groove 2121, the second rotating shaft 4 may penetrate through the receiving groove 2121, and a portion of the first sliding part 211, which is engaged with the second rotating shaft 4, may be disposed in the receiving groove 2121, so that when the first sliding part 211 slides along the second rotating shaft 4 under the action of the connecting rod 232, the first sliding part 211 may transmit force to the second sliding part 212 through a side wall of the receiving groove 2121, so as to drive the second sliding part 212 to slide along the second rotating shaft 4.

In some cases, the first sliding member 211 can be provided with a third surface opposite to the first plane 41 of the second rotating shaft 4, so that when the second rotating part 222 of the rotating member 22 rotates, the first sliding member 211 can also rotate relative to the seat 24 through the action between the first plane 41 and the third plane; in other cases, the third plane may not be disposed on the first sliding member 211, and the first sliding member 211 slides only along the second rotating shaft 4. The design can be specifically designed according to actual sports requirements, and the disclosure does not limit the design.

For example, as shown in fig. 3 and 8, the fixing member 1 includes a first fixing member and a second fixing member, and when the hinge member 100 is in the unfolded state, the first fixing member, the second fixing member and the movable element 2 may be arranged side by side, for example, as shown in fig. 3 and 8, the first fixing member is located at the left side of the movable element 2, the second fixing member is located at the right side of the movable element 2, and the movable element 2 is located between the first fixing member and the second fixing member, and when the hinge member 100 is applied to a foldable electronic device, the housings located at both sides may be respectively fixed by the first fixing member and the second fixing member, so as to fold and unfold the electronic device. The connection between the first fixing member and the movable assembly 2 and the compensation member 3 can refer to the foregoing embodiments, and the connection between the second fixing member and the movable assembly 2 and the compensation member 3 can refer to the foregoing embodiments, which are not described in detail herein.

The compensation part 3 includes a first compensation part and a second compensation part, for example, in the embodiment provided in the present disclosure, the first compensation part may be slidably connected to the first fixing part, the second compensation part may be slidably connected to the second fixing part, and the structures of the first compensation part and the second compensation part may specifically refer to the foregoing embodiment, and are not described in detail herein. The sliding portion 21 may further include a third sliding member 213, the third sliding member 213 may be slidably disposed along the second direction, and specifically, the third sliding member 213 may be engaged with the second rotating shaft 4 to be slidably disposed relative to the seat body 24, as in the embodiment provided in the present disclosure, the third sliding member 213 is disposed on the left side, the second sliding member 212 is disposed on the right side, and the third sliding member 213 may be slidably connected to the first compensating member, so as to drive the first compensating member to rotate relative to the rotating member 22 disposed close to the first fixing member when the third sliding member 213 slides along the second direction, and further drive the first fixing member to be far away from or close to the seat body 24.

The second sliding part 212 can be slidably connected with the second compensation part, and the third sliding part 213 can also be engaged with the first sliding part 211, and the specific engagement can refer to the engagement between the first sliding part 211 and the second sliding part 212. Based on this, when the second rotating portion 222 of the rotating component 22 rotates relative to the seat 24, the first sliding component 211 can be driven by the second rotating shaft 4 to slide along the second direction, and then the second compensation component can be driven by the second sliding component 212 to rotate relative to the second matching portion 224 of the rotating component 22, and the first compensation component can be driven by the third sliding component 213 to rotate relative to the rotating component 22 located on the same side as the first compensation component; the third sliding part 213 can be provided with a third plane, the movable assembly 2 can include a second rotating shaft 4 disposed close to the first fixed part and a second rotating shaft 4 disposed close to the second fixed part, and the second rotating shaft 4 disposed close to the first fixed part can penetrate through the rotating part 22, the first sliding part 211 and the third sliding part 213 disposed close to the first fixed part; the second rotating shaft 4 near the second fixed part can be inserted through the rotating part 22, the first sliding part 211 and the second sliding part 212 near the second fixed part, so that when the rotating part 22 near the first fixed part or the rotating part 22 near the second fixed part rotates relative to the seat body 24, the second sliding part 212 and the third sliding part 213 can be synchronously driven by the first sliding part 211 to slide along the second direction, so that the synchronous motion of the first compensating part and the second compensating part can be realized, the first fixed part and the second fixed part can be synchronously far away from the seat body 24 or near the seat body 24, and the first fixed part and the second fixed part on the hinge part 100 can be folded in half; when the rotating part 22 close to the first fixed part rotates around the second direction, the third sliding part 213 can be driven to rotate around the second direction, so as to drive the first compensation part to rotate along with the third sliding part 213, and adapt to the movement of the first fixed part driving the first compensation part; when the rotating part 22 close to the second fixed part rotates around the second direction, the second sliding part 212 can be driven to rotate around the second direction, so as to drive the second compensating part to rotate along with the second sliding part 212, and adapt to the movement of the second fixed part driving the second compensating part. The first sliding part 211, the second sliding part 212 and the third sliding part 213 cooperate to realize synchronous doubling back between the first fixing part and the second fixing part, which is beneficial to simplifying the structure of the hinge component 100 compared with the scheme of realizing synchronization by adopting the structure of the gear 231 in the related art.

In the above embodiment, the first sliding member 211 drives the second sliding member 212 and the third sliding member 213 to move synchronously, but in other embodiments, a plurality of first sliding members 211 may be provided, wherein one first sliding member 211 is engaged with the second sliding member 212, one first sliding member 211 is engaged with the third sliding member 213, and then the transmission member 23 drives the plurality of first sliding members 211 to slide synchronously, so that the first fixing member and the second fixing member can be driven to move away from the seat body 24 or close to the seat body 24 synchronously. In this embodiment, it is necessary to prevent the first sliding member 211 from rotating relative to the seat body 24, so the first sliding member penetrates through the hole of the second rotating shaft 4.

In this embodiment, in order to maintain the hinge member 100 in the folded state, the hinge member 100 may further include a first magnet (not shown) that may be used to be connected to a first device end of the electronic device to which the hinge member 100 is configured, and a second magnet (not shown) that may be used to be connected to a second device end of the electronic device to which the hinge member 100 is configured, the first and second fixing members being disposed opposite to each other when the hinge member 100 is in the folded state, the first and second device ends being folded in half such that the first and second magnets attract each other, and a relative positional relationship between the first device end connected to the first fixing member and the second device end connected to the second fixing member, such as the first and second device ends, being maintained in the folded state, is established by a force generated by attraction between the first and second magnets.

It can be understood that, as shown in fig. 1 and 2, when the hinge assembly 100 is switched to the folded state, the first fixing part and the second fixing part are substantially perpendicular to the seat body 24 of the movable assembly 2, so that in order to avoid that when the hinge assembly is switched to the folded state, the second sliding part 212 and the third sliding part 213 protrude by rotating relative to the seat body 24 to affect parts in the electronic device or occupy space in the electronic device. Taking the second sliding member 212 as an example, the second sliding member 212 may include a third connecting portion 2122, a transition portion 2123 and a fourth connecting portion 2124, the third connecting portion 2122 may be slidably disposed along the second direction relative to the base 24, specifically, the third connecting portion 2122 may penetrate the second rotating shaft 4, and the receiving groove 2121 may be disposed on the third connecting portion 2122; the transition portion 2123 has one end connected to the third connecting portion 2122 and the other end connected to the fourth connecting portion 2124, and when the hinge member 100 is in the unfolded state, the extending direction of the transition portion 2123 is perpendicular to the first direction and the second direction, and the extending direction of the third connecting portion 2122 is parallel to the extending direction of the fourth connecting portion 2124. Based on this, when the hinge member 100 is switched from the unfolded state to the folded state, the third connecting portion 2122, the transition portion 2123 and the fourth connecting portion 2124 are respectively rotated by about 90 ° with respect to the seat body 24, and there is no additional protruding portion to occupy space. The structure of the third sliding member 213 can refer to the structure of the second sliding member 212, and is not described in detail here.

In the above embodiments, the movable assembly 2 may further include an elastic member 25, the elastic member 25 may be used for fixing, and in particular, the elastic member 25 may be disposed between the base 241 and the cover 242, one end of the elastic member 25 is used for fixedly connecting with the base 241, the other end of the elastic member 25 may be connected with the sliding portion 21, and in particular, may be connected with the first sliding member 211, and of course, when the sliding portion 21 includes a single part, that is, connected with the single part, the deformation direction of the elastic member 25 is disposed along the second direction. Based on this, when the hinge assembly 100 is switched to the folded state, the second rotating portion 222 of the rotating member 22 can rotate relative to the seat body 24, the sliding portion 21 can slide along the second direction and compress the elastic member 25, so that the elastic member 25 is deformed and accumulated, and the elastic member 25 can be prevented from being deformed again by the limiting action of the first magnet and the second magnet, although the relative position relationship between the fixing member 1 and the seat body 24 can be limited by other parts in the folded state, which is not limited by the present disclosure; when the hinge assembly 100 is forced to switch to the unfolded state, the elastic member 25 is reset to push the sliding portion 21 to slide along the second direction, the sliding portion 21 pushes the connecting rod 232 and the gear 231 of the transmission member 23 to move, and the gear 231 can drive the rotating member 22 to rotate around the second direction, so that the purpose of saving labor can be achieved in the process of switching the hinge assembly 100 to the unfolded state.

In the above embodiments, as shown in fig. 9, the first matching portion 223 of the rotating member 22 may further include the protruding portion 2231, the hinge member 100 may further include the screen support member 5, the screen support member 5 may include the support main body 51 and the extending portion 52 extending from the support main body 51 toward the first matching portion 223, the support main body 51 may be substantially in a plate shape, and the support main body 51 in the plate shape may be stacked with the first matching portion 223, as shown in fig. 9, the support main body 51 is located above the first matching portion 223, and the support main body 51 may be subsequently used to support the flexible display panel of the electronic device configuring the hinge member 100, which is beneficial for reducing deformation of the flexible display panel. The extending portion 52 can be connected to the protruding portion 2231, so that when the rotating member 22 rotates around the second direction, the protruding portion 2231 on the first matching portion 223 can push the screen supporting member 5 to rotate relative to the movable assembly 2, thereby adapting to the deformation of the electronic device generated by the fixing member 1, and avoiding pulling the flexible display screen of the electronic device.

Specifically, the extension 52 includes an arc-shaped fitting groove 521, the protrusion 2231 may extend into the arc-shaped fitting groove 521 to fit into the arc-shaped fitting groove 521, the support body 51 may include an arc-shaped guide rail 511 provided at the edge, and the fixing member 1 may include an arc-shaped guide groove 11 to fit with the arc-shaped guide rail 511; when the rotating part rotates about the second direction relative to the base body 24, the protrusion 2231 can slide in the arc-shaped matching groove 521, and the arc-shaped guide rail 511 slides relative to the arc-shaped guide groove 11, so that when the hinge part 100 is switched to the folded state, the screen support 5 is far away from the movable assembly 2, and when the hinge part 100 is switched to the unfolded state, the screen support 5 is close to the movable assembly 2. Based on this, when the hinge member 100 is switched to the folded state, the change of the relative position between the fixing member 1 and the support main body 51 can be accommodated by the cooperation of the arc-shaped guide groove 11 and the arc-shaped guide rail 511, and the movement of the fixing member 1 is prevented from being locked.

The arc-shaped guide rails 511 may be disposed in a semicircular shape, the cross section of the arc-shaped guide groove 11 may also be disposed in a semicircular shape, and the radius of the arc-shaped guide rails 511 may be smaller than the radius of the arc-shaped guide groove 11, and the semicircular arc-shaped guide rails 511 may extend into the semicircular arc-shaped guide groove 11, when the fixing member 1 rotates relative to the base body 24 under the action of the rotating member 22 and is far away from or close to the base body 24 under the action of the compensating member 3, the position change of the fixing member 1 and the position change of the screen supporting member 5 may be adapted through the movement of the arc-shaped guide rails 511 in the arc-shaped guide groove 11, so as to avoid the fixing member 1 from pulling the screen supporting member 5 to cause the flexible display screen of the electronic device to be pulled. Of course, only the arc-shaped guide rail 511 and the arc-shaped guide groove 11 are illustrated as being semicircular, and in other embodiments, the arc-shaped guide rail 511 and the arc-shaped guide groove 11 may be disposed in other arc shapes, which is not limited by the present disclosure. The arc-shaped fitting groove 521 on the extension portion 52 can be designed according to the locus of the relative movement between the support main body 51 and the holder body 24.

In some cases, the first engaging portion 223 may have an elongated shape, and a sliding groove or a sliding rail for engaging with the fixing element 1 is disposed on each of two sides of the elongated first engaging portion 223, and the protruding portion 2231 may also be disposed on the elongated first engaging portion 223 without interference. In other cases, as in the embodiments provided by the present disclosure, the first mating portion 223 may include a first sub-portion 2232 and a second sub-portion 2232 that are spaced apart from each other, the first sub-portion 2232 and the second sub-portion 2232 may be slidably connected to the fixing member 1, respectively, and the extending portion 52 may extend between the first sub-portion 2232 and the second sub-portion 2232, and the protruding portion 2231 may be disposed on at least one of the first sub-portion 2232 and the second sub-portion 2232. Therefore, the extension portion 52 is accommodated in the gap between the first sub-portion 2232 and the second sub-portion 2232, which is beneficial to reducing the thickness of the hinge component 100, and is in line with the trend of light and thin electronic devices. In some cases, the protrusion 2231 may be formed to extend from a surface of the first sub-portion 2232 or the second sub-portion 2232, and in other cases, the rotating member 22 may further include a pin disposed along the second direction, and the pin may sequentially penetrate the first sub-portion 2232, the extending portion 52, and the second sub-portion 2232, and form the protrusion 2231, so as to achieve the connection between the extending portion 52 and the first matching portion 223. It should be noted that, when the fixing part 1 includes a first fixing part and a second fixing part, the screen supporting part 5 may also include a first screen supporting part matched with the first fixing part and a second screen supporting part matched with the second fixing part, and the specific implementation may refer to the foregoing embodiments, and details are not repeated here.
