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.

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.

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 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.

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.

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 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.
