[0037] An electronic device 200 provided in the present application includes a hinge assembly 100 and at least two mounting frames 130, wherein the hinge assembly 100 includes a keel 110 and at least two supporting components 120, wherein through the hinge assembly 100, a user can fold or unfold a screen assembly 220 according to actual needs, thereby improving the functionality of the electronic device 200. The keel 110 is provided with a first slide groove 112 extending in an arc shape; the support component 120 includes a first sliding portion 122, a second sliding portion 124 and a plate body 126, the first sliding portion 122 is provided in the first slide groove 112, and the first sliding portion 122 can slide along the first slide groove 112, one end of the plate body 126 is connected to the first sliding portion 122, and the second sliding portion 124 is connected to the other end of the plate body 126; the mounting frame 130 is provided with a second slide groove 132 extending in an arc shape, the second sliding portions 124 of at least two support components 120 are respectively provided in the second slide grooves 132 of at least two mounting frames 130, and the second sliding portion 124 can slide along the second slide groove 132. Among them, when the electronic device 200 is in the unfolded state, the first sliding portion 122 is in the first position relative to the first slide groove 112, and the plate body 126 is used to support the screen assembly 220, improve the stability of the screen assembly 220, facilitate the user to operate the electronic device 200, and improve the tactile experience of the user when operating the electronic device 200. When the electronic device 200 is in the folded state, the first sliding part 122 is in the second position relative to the first sliding groove 112; when the first sliding part 122 is in the first position, compared with the first sliding part 122 in the second position, when the first sliding part 122 is in the first position, the first sliding part 122 is located in the first sliding groove 112. More parts, so that the first sliding part 122 can slide flexibly in the first sliding groove 112, and a sliding space is reserved for the first sliding part 122, so that the electronic device 200 can be folded and unfolded. The first sliding groove 112 and the second sliding groove 132 extending in an arc shape can ensure the smoothness and continuity of the first sliding part 122 and the second sliding part 124 during the sliding process, reduce the jamming and resistance during the sliding process, so that the first sliding part 122 and the second sliding part 124 can move smoothly in the sliding groove. The plate body 126 is used to support the screen assembly 220, improve the stability of the screen assembly 220, and facilitate the user to operate the electronic device 200. Since the second sliding part 124 and the first sliding part 122 are respectively connected to the plate body 126, it is possible to support the screen through the plate body 126 while the first sliding part 122, the second sliding part 124 and the plate body 126 form a swing arm, thereby saving the original structure of the swing arm connecting the first sliding part 122 and the second sliding part 124, reducing the overall thickness of the hinge, and thereby reducing the space occupied.

[0038] At least two mounting brackets 130 are provided with second slide grooves 132 extending in an arc shape, and the mounting brackets 130 can be used to mount the frame 210 of the electronic device 200 to improve the stability of the structure. At the same time, the first sliding portion 122 is arranged in the first slide groove 112, and the second sliding portions 124 of at least two supporting components 120 are arranged in the second slide groove 132, so that the first sliding portion 122, the second sliding portion 124 and the plate 126 can be rotated relative to the keel 110, thereby realizing the switching of the electronic device between the unfolded state and the folded state.

[0039] By using the plate body 126 as a connector connecting the first sliding part 122 and the second sliding part 124, the connection structure can be simplified, and no additional door panel or connector is required, thereby reducing the overall thickness of the hinge assembly 100 and the space occupied by the hinge assembly 100 inside the electronic device 200. While ensuring the reliability of the screen assembly 220, the electronic device 200 can be designed to be lightweight.

[0040] By providing the mounting frame 130 with a second slide groove 132 and the second sliding portion 124 in the second slide groove 132, the stability of the support component 120 in the hinge assembly 100 can be improved. When the electronic device 200 falls in a folded state, the support component 120 can be prevented from sliding and causing damage to the screen assembly 220, thereby improving the stability and structural reliability of the electronic device 200.

[0041] Furthermore, by setting the first sliding part 122 and the second sliding part 124 to slide in the slide groove, the support component 120 can be flexibly rotated and adjusted relative to the keel 110 and the mounting frame 130, so that the screen assembly 220 of the electronic device 200 can be easily opened, closed and adjusted to different angles to meet the user's usage needs in different scenarios.

[0042] Furthermore, the plate body 126 can support the screen assembly 220. By respectively connecting the plate body 126 to the first sliding part 122 and the second sliding part 124, the screen assembly 220 can be effectively buffered and protected when impacted by external force, thereby extending the overall service life of the electronic device 200.

[0043] Furthermore, the arc-shaped slide groove and the sliding portion can be rotated within a limited space, making the overall structure more compact, which is beneficial to saving space and improving design flexibility.

[0044] Specifically, the keel 110 includes a first body 230, a second body 232 and a third body 234. The first chute includes a first sub-chute 240 and a second sub-chute 242. The first sub-chute 240 is provided between the first body 230 and the second body 232, and the second sub-chute 242 is provided between the first body 230 and the third body 234.

[0045] The first sliding part 122, the second sliding part 124 and the plate body 126 are an integrated structure, which can simplify the connection structure between the first sliding part 122, the second sliding part 124 and the plate body 126, and there is no need to reserve installation space for additional connection structures, thereby reducing the space occupied by the first sliding part 122, the second sliding part 124 and the plate body 126, reducing the thickness of the electronic device 200, and realizing a lightweight design of the electronic device 200.

[0046] Furthermore, the first sliding part 122, the second sliding part 124 and the plate body 126 can also be set as a split structure. Since the first sliding part 122, the second sliding part 124 and the plate body 126 are connected to each other, there is no need to additionally set a swing arm to connect the first sliding part 122 and the second sliding part 124, thereby simplifying the structure and reducing the thickness of the hinge assembly 100.

[0047] Specifically, the first sliding part 122 , the second sliding part 124 and the plate body 126 can be connected by snap fasteners, thereby reducing the thickness and the production cost.

[0048] According to some embodiments of the present application, the electronic device 200 also includes a floating plate 140, which is arranged on a side of the keel 110 close to the screen assembly 220; wherein, when the electronic device 200 is in an unfolded state, the floating plate 140 is in a first position, and a side of the first sliding portion 122 away from the plate body 126 abuts against a side of the floating plate 140 close to the keel 110; when the electronic device 200 is in a folded state, the floating plate 140 is in a second position, and relative to when the floating plate 140 is in the first position, the floating plate 140 is closer to the keel 110.

[0049] In this embodiment, the electronic device 200 further includes a floating plate 140, which is disposed on a side of the keel 110 close to the screen assembly 220; wherein, when the electronic device 200 is in the unfolded state, the floating plate 140 is in the first position, and the side of the first sliding portion 122 away from the plate body 126 abuts against the side of the floating plate 140 close to the keel 110; when the electronic device 200 is in the folded state, the floating plate 140 is in the second position, and the floating plate 140 is closer to the keel 110 than when the floating plate 140 is in the first position. When the electronic device 200 is in the unfolded state, the floating plate 140 is in the first position, and the side of the first sliding portion 122 away from the plate body 126 abuts against the side of the floating plate 140 close to the keel 110, so that the floating plate 140 and the plate body 126 can jointly support the screen assembly 220, effectively dispersing the pressure of the screen assembly 220 in the unfolded state, and improving the flatness and stability of the screen assembly 220. When the electronic device 200 is in the folded state, the floating plate 140 is in the second position, which is closer to the keel 110 than when the floating plate 140 is in the first position, so that the floating plate 140 can provide more buffer space for the screen assembly 220 during the folding process, thereby preventing the screen assembly 220 from being excessively squeezed or worn during the folding process. At the same time, the movement of the floating plate 140 can also help adjust the folding angle of the screen assembly 220, ensuring that the screen can fit tightly in the folded state and reducing the generation of creases.

[0050] Furthermore, during the folding process, the movement of the floating plate 140 can guide the screen assembly 220 to fold along a predetermined trajectory, reducing resistance and friction during the folding process. During the unfolding process, the floating plate 140 can assist the screen assembly 220 to unfold smoothly, avoiding damage to the screen due to sudden force.

[0051] Specifically, by supporting the floating plate 140, improving the flatness between the floating plate 140 and the plate body 126, and improving the flatness of the screen assembly 220, the gap between the door panel and the screen can be reduced to less than 0.05 mm, reducing the folding deformation of the screen assembly 220, strengthening the support for the screen assembly 220, and optimizing the crease of the screen assembly 220. The floating plate 140 is folded and sunk in the middle, which can further increase the screen space and reduce the squeezing of the screen by the hinge in the folded state.

[0052] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to some embodiments of the present application, the support component 120 also includes a support portion 128, which is disposed on a side of the plate body 126 close to the floating plate 140; wherein, when the electronic device 200 is in the unfolded state, the support portion 128 rests against a side of the floating plate 140 close to the keel 110.

[0053] In this embodiment, the support component 120 also includes a support portion 128, and the support portion 128 is arranged on a side of the plate body 126 close to the floating plate 140; wherein, when the electronic device 200 is in the unfolded state, the support portion 128 abuts against a side of the floating plate 140 close to the keel 110, which can improve the structural stability. At the same time, the support portion 128 can provide additional support for the screen assembly 220. When the screen assembly 220 is subjected to external force in the unfolded state of the electronic device 200, the support portion 128 can effectively disperse and absorb these forces, thereby enhancing the stability of the entire structure.

[0054] According to some embodiments of the present application, the electronic device 200 also includes a first elastic member 142, one end of the first elastic member 142 is connected to the keel 110, and the other end of the first elastic member 142 is connected to the floating plate 140; wherein, when the floating plate 140 is in the first position, the first elastic member 142 is in a stretched state.

[0055] In this embodiment, the electronic device 200 also includes a first elastic member 142, one end of the first elastic member 142 is connected to the keel 110, and the other end of the first elastic member 142 is connected to the floating plate 140; wherein, when the floating plate 140 is in the first position, the first elastic member 142 is in a stretched state, and the first elastic member 142 at this time has elastic potential energy. When the floating plate 140 is in the second position, the first elastic member 142 releases the elastic potential energy, so that the floating plate 140 is automatically reset, reserving space for the screen assembly 220, increasing the screen space, and improving the reliability of the main screen.

[0056] Specifically, Figure 5 As shown, when the floating plate 140 is in the first position, the first elastic member 142 is in a stretched state.

[0057] like Figure 6 As shown, the first elastic member 142 is in a compressed state, so that the floating plate 140 can be automatically reset, and space can be reserved for the screen assembly 220, thereby increasing the screen space and improving the reliability of the main screen.

[0058] like Figure 7 As shown, according to some embodiments of the present application, the electronic device 200 also includes a first magnetic component 144 and a second magnetic component 146. The first magnetic component 144 is arranged on the keel 110; the second magnetic component 146 is arranged on the floating plate 140 and is opposite to the first magnetic component 144. The second magnetic component 146 can adsorb the first magnetic component 144.

[0059] In this embodiment, the electronic device 200 further includes a first magnetic member 144 and a second magnetic member 146. The first magnetic member 144 is disposed on the keel 110; the second magnetic member 146 is disposed on the floating plate 140 and is opposite to the first magnetic member 144. The second magnetic member 146 can absorb the first magnetic member 144. When the electronic device 200 is in the unfolded state, the floating plate 140 is in the first position. At this time, the side of the first sliding portion 122 away from the plate body 126 abuts against the side of the floating plate 140 close to the keel 110, so that the floating plate 140 and the plate body 126 can jointly support the screen assembly 220, thereby increasing the distance between the first magnetic member 144 and the second magnetic member 146. When the electronic device 200 is in a folded state, the floating plate 140 is in a second position, which is closer to the keel 110 than when the floating plate 140 is in the first position. The first magnetic member 144 and the second magnetic member 146 are attracted to each other, which can shorten the distance between the floating plate 140 and the keel 110, and can help adjust the folding angle of the screen assembly 220, ensuring that the screen assembly 220 can fit tightly in the folded state and reducing the generation of creases.

[0060] like Figure 5 As shown, according to some embodiments of the present application, the keel 110 is provided with a first buckle position 150, and the floating plate 140 is provided with a first buckle 152. The first buckle 152 can slide in the first buckle position 150. When the floating plate 140 is in the first position, the first buckle 152 abuts against the first buckle position 150.

[0061] In this embodiment, the keel 110 is provided with a first buckle position 150, and the floating plate 140 is provided with a first buckle 152. The first buckle 152 can slide in the first buckle position 150. When the floating plate is in the first position and the floating plate 140 is in the first position, the first buckle 152 abuts against the first buckle position 150. Through the mutual cooperation between the first buckle 152 and the first buckle position 150, the floating plate 140 can be limited while the floating plate 140 is movable, and when the floating plate 140 is in the first position, the stability of the structure is improved.

[0062] like Figure 1 , Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, according to some embodiments of the present application, the mounting frame 130 is provided with a third slide groove 134, the hinge assembly 100 also includes a rotating shaft 160, a first synchronous swing arm 162 and a synchronous cam 170, the rotating shaft 160 is arranged on the keel 110, the first synchronous swing arm 162 includes a first rotating part 164 and a third sliding part 166, the first rotating part 164 is sleeved on the rotating shaft 160, the third sliding part 166 is connected to the first rotating part 164 and is located in the third slide groove 134, the synchronous cam 170 is sleeved on the rotating shaft 160, and contacts with the first rotating part 164, and the first contact surface 172 of the synchronous cam 170 in contact with the first rotating part 164 is arranged to be inclined relative to the circumference of the rotating shaft 160.

[0063] In this embodiment, the mounting frame 130 is provided with a third slide groove 134, and the hinge assembly 100 further includes a rotating shaft 160, a first synchronous swing arm 162 and a synchronous cam 170. The rotating shaft 160 is provided on the keel 110 to improve the smoothness during rotation. The first synchronous swing arm 162 includes a first rotating portion 164 and a third sliding portion 166. The first rotating portion 164 is sleeved on the rotating shaft 160 to realize the rotation of the first synchronous swing arm 162 relative to the rotating shaft 160. The third sliding portion 166 is connected to the first rotating portion 164 and is located in the third slide groove 134. The synchronous cam 170 is sleeved on the rotating shaft 160 and contacts the first rotating portion 164. The first contact surface 172 of the synchronous cam 170 in contact with the first rotating portion 164 is arranged obliquely relative to the circumference of the rotating shaft 160. When the rotating shaft 160 rotates, the synchronous cam 170 pushes the first rotating part 164 to move in a specific direction, making the movement of the first synchronous swing arm 162 more precise and controllable, which helps to achieve smooth folding and unfolding of the hinge assembly 100, reduce friction and resistance during folding and unfolding, improve the smoothness and convenience of operation, and improve the flatness of the door panel.

[0064] Specifically, the circumferential direction of the rotating shaft 160 is the direction F1.

[0067] like Figure 7 , Fig.12 and Fig.13 As shown, by supporting the floating plate 140, improving the flatness between the floating plate 140 and the plate body 126, and improving the flatness of the screen assembly 220, the gap between the door panel and the screen can be reduced to less than 0.05 mm, reducing the folding deformation of the screen assembly 220, strengthening the support for the screen assembly 220, and optimizing the crease of the screen assembly 220. The floating plate 140 is folded and sunk in the middle, which can further increase the screen space and reduce the squeezing of the folded hinge on the screen assembly 220.

[0068] Specifically, the screen assembly 220 may be a flexible screen.

[0069] According to some embodiments of the present application, the electronic device 200 also includes a first damping cam 190, a second damping cam 192, a second elastic member 194 and a baffle 196.

[0076] In this embodiment, the cover 198 can make the hinge assembly 100 neater in appearance.

When the hinge assembly 100 needs to be maintained or repaired, the cover 198 can be removed to maintain the interior of the hinge assembly 100.

[0077] According to some embodiments of the present application, the first slide groove 112 extends in an arc shape, and the first sliding portion 122 extends in an arc shape and can slide in the first slide groove 112; the second slide groove 132 extends in an arc shape, and the second sliding portion 124 is located on the side of the plate 126 away from the screen assembly 220, extends in an arc shape, and can slide in the second slide groove 132.

Furthermore, the arc-shaped slide groove and the sliding part can be rotated in a limited space, making the overall structure more compact, which is conducive to saving space and improving the flexibility of design.

[0079] According to some embodiments of the present application, the first sliding portion 122 , the second sliding portion 124 and the plate body 126 are an integrated structure.

[0080] In this embodiment, the first sliding part 122, the second sliding part 124 and the plate body 126 are an integrated structure. The connection structure between the first sliding part 122, the second sliding part 124 and the plate body 126 can be simplified, and there is no need to reserve installation space for additional connection structures, thereby reducing the space occupied by the first sliding part 122, the second sliding part 124 and the plate body 126, reducing the thickness of the electronic device 200, and realizing a lightweight design of the electronic device 200.

[0083] like Figure 1 and Fig. 22 As shown, by setting the hinge assembly 100, the flatness of the screen assembly 220 can be improved, so that the crease of the screen assembly 220 at E is reduced.

[0084] like Figure 1 and Fig.23 As shown, by providing the hinge assembly 100, a screen space G can be reserved inside the electronic device 200, which can prevent the electronic device 200 from falling in the folded state and causing damage to the screen assembly 220, thereby improving the structural strength and durability of the electronic device 200.
