Detailed Implementation

[0034] The embodiments of this application will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0035] The following is combined with Figures 1 to 23 This application describes an electronic device according to an embodiment of the present application.

[0036] like Figure 1 and Figure 2As shown, according to some embodiments of this application, an electronic device 200 includes a hinge assembly 100 and at least two mounting brackets 130. The hinge assembly 100 includes a frame 110 and at least two support members 120. The frame 110 is provided with a first sliding groove 112 extending in an arc shape. The support member 120 includes a first sliding portion 122, a second sliding portion 124, and a plate 126. The first sliding portion 122 is disposed in the first sliding groove 112 and is slidable along the first sliding groove 112. One end of the plate 126 is connected to the first sliding portion 122, and the second sliding portion 124 is connected to the other end of the plate 126. The mounting bracket 130 is provided with a second sliding groove 132 extending in an arc shape. The second sliding portions 124 of the two supporting components 120 are respectively disposed in the second slide grooves 132 of the at least two mounting brackets 130, and the second sliding portions 124 are slidable along the second slide grooves 132; wherein, when the electronic device 200 is in the unfolded state, the first sliding portion 122 is in a first position relative to the first slide groove 112, and the plate 126 is used to support the screen assembly 220; when the electronic device 200 is in the folded state, the first sliding portion 122 is in a second position relative to the first slide groove 112; compared with the first sliding portion 122 being in the second position, when the first sliding portion 122 is in the first position, the portion of the first sliding portion 122 located within the first slide groove 112 is larger.

[0037] The present application provides an electronic device 200, which includes a hinge assembly 100 and at least two mounting brackets 130. The hinge assembly 100 includes a keel 110 and at least two support members 120. Through the hinge assembly 100, the user can fold or unfold the screen assembly 220 according to actual needs, thereby improving the functionality of the electronic device 200. The keel 110 is provided with a first sliding groove 112 extending in an arc shape; the support component 120 includes a first sliding part 122, a second sliding part 124, and a plate 126. The first sliding part 122 is disposed in the first sliding groove 112 and can slide along the first sliding groove 112. One end of the plate 126 is connected to the first sliding part 122, and the second sliding part 124 is connected to the other end of the plate 126; the mounting bracket 130 is provided with a second sliding groove 132 extending in an arc shape. The second sliding parts 124 of at least two support components 120 are respectively disposed in the second sliding grooves 132 of at least two mounting brackets 130, and the second sliding parts 124 can slide along the second sliding grooves 132. When the electronic device 200 is in the unfolded state, the first sliding part 122 is in a first position relative to the first sliding groove 112, and the plate 126 is used to support the screen assembly 220, improving the stability of the screen assembly 220, facilitating user operation of the electronic device 200, and improving the tactile experience when the user operates the electronic device 200. When the electronic device 200 is in a folded state, the first sliding part 122 is in a second position relative to the first slide groove 112. Compared to the second position, when the first sliding part 122 is in the first position, a larger portion of the first sliding part 122 is located within the first slide groove 112, allowing for flexible sliding within the first slide groove 112 and reserving sliding space for the first sliding part 122, thus enabling the folding and unfolding of the electronic device 200. The arc-shaped extension of the first slide groove 112 and the second slide groove 132 ensures the smoothness and continuity of the sliding of the first sliding part 122 and the second sliding part 124 during the sliding process, reducing jamming and resistance during the sliding process, allowing the first sliding part 122 and the second sliding part 124 to move smoothly within the slide groove. The plate 126 is used to support the screen assembly 220, improving the stability of the screen assembly 220 and facilitating user operation of the electronic device 200. Since the second sliding part 124 and the first sliding part 122 are respectively connected to the plate 126, the first sliding part 122, the second sliding part 124 and the plate 126 can form a swing arm while supporting the screen through the plate 126. This saves the original structure of the swing arm connecting the first sliding part 122 and the second sliding part 124, reduces the overall thickness of the hinge, and thus reduces the space occupied.

[0038] At least two mounting brackets 130 are provided with arc-shaped extended second sliding grooves 132. 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 part 122 is provided in the first sliding groove 112, and the second sliding parts 124 of at least two support members 120 are provided in the second sliding groove 132. This allows the first sliding part 122, the second sliding part 124 and the plate 126 to rotate relative to the keel 110, thereby realizing the switching between the unfolded state and the folded state of the electronic device.

[0039] By using the plate 126 as a connector to connect the first sliding part 122 and the second sliding part 124, the connection structure can be simplified, eliminating the need for additional door panels or connectors, reducing the overall thickness of the hinge assembly 100, and reducing the space occupied by the hinge assembly 100 inside the electronic device 200. This achieves a thinner and lighter design for the electronic device 200 while ensuring the reliability of the screen assembly 220.

[0040] By providing a second slide groove 132 to the mounting bracket 130 and a second sliding part 124 to the second slide groove 132, the stability of the support member 120 inside the hinge assembly 100 can be improved. When the electronic device 200 falls in a folded state, the support member 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 groove, the support component 120 can rotate and adjust flexibly relative to the keel 110 and the mounting bracket 130, so that the screen component 220 of the electronic device 200 can be easily opened, closed and adjusted at different angles to meet the user's needs in different scenarios.

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

[0043] Furthermore, the arc-shaped groove and sliding part can rotate within a limited space, making the overall structure more compact, which helps to save space and improve design flexibility.

[0044] Specifically, the keel 110 includes a first body 230, a second body 232, and a third body 234. The first slide groove includes a first sub-slide groove 240 and a second sub-slide groove 242. The first sub-slide groove 240 is provided between the first body 230 and the second body 232, and the second sub-slide groove 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 126 are integrated into one structure, which simplifies the connection structure between the first sliding part 122, the second sliding part 124 and the plate 126. There is no need to reserve installation space for additional connection structure, thereby reducing the space occupied by the first sliding part 122, the second sliding part 124 and the plate 126, reducing the thickness of the electronic device 200, and realizing the thin and light design of the electronic device 200.

[0046] Furthermore, the first sliding part 122, the second sliding part 124 and the plate 126 can also be set as a separate structure. Since the first sliding part 122, the second sliding part 124 and the plate 126 are connected to each other, it is not necessary to set an additional 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 126 can be connected by snap-fit, which reduces the thickness and production costs.

[0048] According to some embodiments of this application, the electronic device 200 further includes a floating plate 140, which is disposed on the side of the keel 110 near the screen assembly 220. When the electronic device 200 is in an unfolded state, the floating plate 140 is in a first position, and the side of the first sliding part 122 away from the plate body 126 abuts against the side of the floating plate 140 near the keel 110. When the electronic device 200 is in a folded state, the floating plate 140 is in a second position, and the floating plate 140 is closer to the keel 110 than when the floating plate 140 is in the first position.

[0049] In this embodiment, the electronic device 200 further includes a floating plate 140, which is disposed on the side of the keel 110 near the screen assembly 220. When the electronic device 200 is in the unfolded state, the floating plate 140 is in a first position, with the side of the first sliding portion 122 away from the plate body 126 abutting against the side of the floating plate 140 near the keel 110. When the electronic device 200 is in the folded state, the floating plate 140 is in a second position, and compared to the first position, the floating plate 140 is closer to the keel 110. 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 abutting against the side of the floating plate 140 near the keel 110 allows the floating plate 140 and the plate body 126 to jointly support the screen assembly 220, effectively dispersing the pressure on 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 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 its first position. This allows the floating plate 140 to provide more buffer space for the screen assembly 220 during folding, preventing the screen assembly 220 from being excessively squeezed or worn. 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 fits tightly in the folded state and reducing the formation 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, the flatness between the floating plate 140 and the plate body 126 is improved, thereby increasing the flatness of the screen assembly 220. This reduces the gap between the door panel and the screen to less than 0.05mm, reduces folding deformation of the screen assembly 220, strengthens the support for the screen assembly 220, and optimizes the creases of the screen assembly 220. The folding and sinking of the floating plate 140 in the middle further increases the screen storage space and reduces the pressure exerted on 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 this application, the support member 120 further includes a support portion 128, which is disposed on the side of the plate 126 near the floating plate 140; wherein, when the electronic device 200 is in the unfolded state, the support portion 128 abuts against the side of the floating plate 140 near the keel 110.

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

[0054] According to some embodiments of this application, the electronic device 200 further includes a first elastic member 142, one end of which is connected to the keel 110 and the other end of which 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 further includes a first elastic element 142. One end of the first elastic element 142 is connected to the keel 110, and the other end of the first elastic element 142 is connected to the floating plate 140. When the floating plate 140 is in the first position, the first elastic element 142 is in a stretched state and has elastic potential energy. When the floating plate 140 is in the second position, the first elastic element 142 releases the elastic potential energy, thereby realizing the automatic reset of the floating plate 140, reserving space for the screen assembly 220, increasing the screen capacity, and improving the reliability of the main screen.

[0056] Specifically, such as 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 element 142 is in a compressed state, which realizes the automatic reset of the floating plate 140, reserves space for the screen assembly 220, increases the screen capacity, and improves the reliability of the main screen.

[0058] like Figure 7 As shown, according to some embodiments of this application, the electronic device 200 further includes a first magnetic element 144 and a second magnetic element 146. The first magnetic element 144 is disposed on the keel 110; the second magnetic element 146 is disposed on the floating plate 140 and is opposite to the first magnetic element 144. The second magnetic element 146 is capable of attracting the first magnetic element 144.

[0059] In this embodiment, the electronic device 200 further includes a first magnetic element 144 and a second magnetic element 146. The first magnetic element 144 is disposed on the keel 110; the second magnetic element 146 is disposed on the floating plate 140 and opposite to the first magnetic element 144, and the second magnetic element 146 can attract the first magnetic element 144. When the electronic device 200 is in the unfolded state, the floating plate 140 is in a first position. At this time, the side of the first sliding part 122 away from the plate body 126 abuts against the side of the floating plate 140 near the keel 110, so that the floating plate 140 and the plate body 126 jointly support the screen assembly 220, increasing the distance between the first magnetic element 144 and the second magnetic element 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 component 144 and the second magnetic component 146 attract each other, which can shorten the distance between the floating plate 140 and the keel 110. This 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 this application, the keel 110 is provided with a first buckle 150, and the floating plate 140 is provided with a first buckle 152. The first buckle 152 can slide within the first buckle 150. When the floating plate 140 is in the first position, the first buckle 152 abuts against the first buckle 150.

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

[0062] like Figure 1 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, according to some embodiments of this application, the mounting bracket 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 disposed 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, and the third sliding part 166 is connected to the first rotating part 164 and located in the third slide groove 134. The synchronous cam 170 is sleeved on the rotating shaft 160 and contacts the first rotating part 164. The first contact surface 172 of the synchronous cam 170 and the first rotating part 164 is arranged circumferentially inclined relative to the rotating shaft 160.

[0063] In this embodiment, the mounting bracket 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 disposed on the keel 110 to improve the smoothness of rotation. 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 to realize the rotation of the first synchronous swing arm 162 relative to 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 the first rotating part 164. The first contact surface 172 of the synchronous cam 170 in contact with the first rotating part 164 is arranged circumferentially inclined relative to the rotating shaft 160. When the pivot 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. This helps to achieve smooth folding and unfolding of the hinge assembly 100, reduces friction and resistance during folding and unfolding, improves the smoothness and convenience of operation, and enhances the flatness of the door panel.

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

[0065] like Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, according to some embodiments of this application, the electronic device 200 further includes a second synchronous swing arm 180, which includes a second rotating part 182 and a fourth sliding part 184. The second rotating part 182 is sleeved on the rotating shaft 160 and contacts the side of the synchronous cam 170 away from the first rotating part 164. The fourth sliding part 184 is connected to the second rotating part 182 and is located in the third slide groove 134. The second contact surface 174 of the synchronous cam 170 and the second rotating part 182 is arranged obliquely relative to the circumferential direction of the rotating shaft 160, and the first contact surface 172 and the second contact surface 174 are parallel.

[0066] In this embodiment, the electronic device 200 further includes a second synchronous swing arm 180, which includes a second rotating part 182 and a fourth sliding part 184. The second rotating part 182 is sleeved on the rotating shaft 160 and contacts the side of the synchronous cam 170 away from the first rotating part 164. The fourth sliding part 184 is connected to the second rotating part 182 and is located in the third slide groove 134. The second contact surface 174 of the synchronous cam 170 and the second rotating part 182 is arranged obliquely relative to the circumferential direction of the rotating shaft 160, and the first contact surface 172 and the second contact surface 174 are parallel. By setting a second synchronous swing arm 180, when rotating along the pivot 160, the synchronous cam 170 will push the second rotating part 182 to move in a specific direction, making the movement of the second synchronous swing arm 180 more precise and controllable. This helps to achieve smooth folding and unfolding of the hinge assembly 100, reduces friction and resistance during folding and unfolding, improves the smoothness and convenience of operation, and enhances the flatness of the door panel. By setting the second contact surface 174 of the synchronous cam 170 and the second rotating part 182 to be circumferentially inclined relative to the pivot 160, and the first contact surface 172 and the second contact surface 174 to be parallel, the synchronization effect can be further improved, making it easier to achieve smooth folding and unfolding of the hinge assembly 100.

[0067] like Figure 7 , Figure 12 and Figure 13 As shown, by supporting the floating plate 140, the flatness between the floating plate 140 and the plate body 126 is improved, thereby increasing the flatness of the screen assembly 220. This reduces the gap between the door panel and the screen to less than 0.05mm, reduces folding deformation of the screen assembly 220, strengthens the support for the screen assembly 220, and optimizes the creases of the screen assembly 220. The folding and sinking of the floating plate 140 in the middle further increases the screen storage space and reduces the pressure exerted on the screen assembly 220 by the hinge in the folded state.

[0068] Specifically, screen component 220 can be a flexible screen.

[0069] According to some embodiments of this application, the electronic device 200 further includes a first damping cam 190, a second damping cam 192, a second elastic member 194, and a baffle 196. The first damping cam 190 is sleeved on the rotating shaft 160 and abuts against the side of the first synchronous swing arm 162 away from the synchronous cam 170. The second damping cam 192 is sleeved on the rotating shaft 160 and abuts against the side of the second synchronous swing arm 180 away from the synchronous cam 170. The second elastic member 194 is sleeved on the rotating shaft 160 and abuts against the side of the first damping cam 190 away from the first synchronous swing arm 162. The baffle 196 is snapped into the rotating shaft 160 and abuts against the side of the second damping cam 192 away from the second synchronous swing arm 180.

[0070] like Figure 10 , Figure 14 , Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, in this embodiment, the electronic device 200 further includes a first damping cam 190, a second damping cam 192, a second elastic element 194, and a baffle 196. The first damping cam 190 is sleeved on the rotating shaft 160 and abuts against the side of the first synchronous swing arm 162 away from the synchronous cam 170. The second damping cam 192 is sleeved on the rotating shaft 160 and abuts against the side of the second synchronous swing arm 180 away from the synchronous cam 170. The second elastic element 194 is sleeved on the rotating shaft 160 and abuts against the side of the first damping cam 190 away from the first synchronous swing arm 162. The baffle 196 is engaged with the rotating shaft 160 and abuts against the side of the second damping cam 192 away from the second synchronous swing arm 180. The first damping cam 190 and the second damping cam 192 abut against the sides of the first synchronous swing arm 162 and the second synchronous swing arm 180 away from the synchronous cam 170, respectively, forming a dual damping control. This slows down the movement speed of the swing arms, making the folding and unfolding process smoother and reducing impact and vibration. The second elastic element 194 is sleeved on the pivot 160 and abuts against the side of the first damping cam 190 away from the first synchronous swing arm 162, providing additional support and cushioning for the entire hinge assembly 100. Furthermore, by setting the size of the first damping cam 190 and the second damping cam 192 to be smaller than that of the synchronous gear, the opening in the upper door panel of the hinge assembly 100 is reduced, increasing the flatness of the door panel and optimizing creases. The first damping cam 190 and the second damping cam 192 provide a certain damping effect when the frame 210 rotates.

[0071] Specifically, by mounting the first damping cam 190 on the rotating shaft 160 and abutting against the side of the first synchronous swing arm 162 away from the synchronous cam 170, and mounting the second damping cam 192 on the rotating shaft 160 and abutting against the side of the second synchronous swing arm 180 away from the synchronous cam 170, it is possible to achieve synchronous rotation of the left and right sides of the electronic device 200 and vertical movement of the body of the electronic device 200 when the user unfolds or folds the electronic device 200. This improves the reliability of the screen assembly 220 and makes it easier for the user to use.

[0072] According to some embodiments of this application, a first limiting groove 154 is provided on the side of the first synchronous swing arm 162 near the screen assembly 220, and the first limiting groove 154 is recessed in the direction away from the screen assembly 220; wherein, when the electronic device 200 is in a folded state, the side of the plate 126 near the keel 110 is located in the first limiting groove 154.

[0073] In this embodiment, a first limiting groove 154 is provided on the side of the first synchronous swing arm 162 near the screen assembly 220, and the first limiting groove 154 is recessed in the direction away from the screen assembly 220; wherein, when the electronic device 200 is in a folded state, the side of the plate 126 near the keel 110 is located within the first limiting groove 154. The first synchronous swing arm 162 can be limited when the electronic device 200 is bent, and the floating plate 140 can be limited, leaving space to avoid damage to the screen assembly 220.

[0074] like Figure 14 and Figure 15 As shown, when the electronic device 200 falls downwards, the first synchronous swing arm 162 can be limited by the first limiting groove 154 to prevent the first synchronous swing arm 162 from shifting, thereby preventing the first synchronous swing arm 162 from damaging the screen assembly 220. This can reserve screen space for the screen assembly 220 and improve the reliability of the electronic device 200.

[0075] According to some embodiments of this application, the second slide 132 has an opening 136 on the side opposite to the screen assembly 220, and the hinge assembly 100 also includes a cover 198, which covers the opening 136 and is connected to the mounting bracket 130.

[0076] In this embodiment, the cover 198 makes the hinge assembly 100 look neater. Simultaneously, the cover 198 reduces noise and vibration generated by the sliding parts during movement, further improving user comfort. When maintenance or repair of the hinge assembly 100 is required, the internal components of the hinge assembly 100 can be accessed by removing the cover 198.

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

[0078] In this embodiment, the first slide groove 112 extends in an arc shape, and the first sliding part 122 extends in an arc shape, allowing it to slide within the first slide groove 112. The second slide groove 132 extends in an arc shape, and the second sliding part 124 is located on the side of the plate 126 away from the screen assembly 220, extending in an arc shape, allowing it to slide within the second slide groove 132. This ensures smoothness and continuity during the sliding process, reduces jamming and resistance during sliding, and allows the first sliding part 122 and the second sliding part 124 to move smoothly within the slide groove. Furthermore, the arc-shaped slide groove and the sliding part can rotate within a limited space, making the overall structure more compact, which is beneficial for saving space and improving design flexibility.

[0079] According to some embodiments of this application, the first sliding part 122, the second sliding part 124 and the plate 126 are an integral structure.

[0080] In this embodiment, the first sliding part 122, the second sliding part 124, and the plate 126 are an integral structure. This simplifies the connection structure between the first sliding part 122, the second sliding part 124, and the plate 126, eliminating the need to reserve installation space for additional connection structures. This reduces the space occupied by the first sliding part 122, the second sliding part 124, and the plate 126, thereby reducing the thickness of the electronic device 200 and achieving a thinner and lighter design for the electronic device 200.

[0081] Specifically, the electronic device 200 can be a foldable screen mobile phone, tablet, or computer.

[0082] like Figure 1 , Figure 10 , Figure 19 and Figure 20 As shown, multiple hinge modules can be configured, meaning each hinge module includes all the structures in the hinge assembly 100. Specifically, hinge module A, hinge module B, hinge module C, and hinge module D can be configured. Using multiple hinge modules can improve structural strength and stability.

[0083] like Figure 1 and Figure 22 As shown, by setting the hinge assembly 100, the flatness of the screen assembly 220 can be improved, thereby reducing the crease of the screen assembly 220 at point E.

[0084] like Figure 1 and Figure 23 As shown, by setting the hinge component 100, a screen space G can be reserved inside the electronic device 200, which can prevent the screen component 220 from being damaged when the electronic device 200 is dropped in the folded state, thereby improving the structural strength and durability of the electronic device 200.

[0085] Specifically, such as Figure 14 , Figure 15 and Figure 21 As shown, during the drop of the foldable electronic device 200, the reaction force at the position of the first synchronous swing arm 162 will be transmitted from the frame 210 to the mounting frame 130, then to the plate 126, and finally to the keel 110. By setting a limiting structure between the first synchronous swing arm 162 and the plate 126, the internal support strength of the folded electronic device 200 can be improved, preventing the structure from shifting and damaging the screen assembly 220 during the drop.
