[0061] Therefore, the folding hinge can realize the synchronous movement of the two parts in the folding hinge 01 by changing the structure design of the folding hinge 01.

[0062] Specifically, as shown in Figure 7 or Figure 8 Each set of folding assemblies 3 comprises a synchronous support plate 31 and a damping structure 32 arranged on the synchronous support plate 31, wherein: the synchronous support plate 31 is pivoted to the base assembly 1, and the synchronous support plate 31 is engaged with the gear set 4; the damping structure 32 comprises a sliding part for slidingly cooperating with the screen support plate 2 and a damping part for slidingly and frictionally cooperating with the screen support plate 2.

The main body part 3211 of each damping block 321 away from the side end face of the other damping block 321 forms a limiting surface B for matching the damping block mounting hole 311.

[0069] In this embodiment, each damping block 321 is installed in the damping block mounting hole 311, a damping spring 322 is arranged between the two damping blocks 321, the damping spring 322 presses the damping blocks 321, the limiting surface B of each damping block 321 abuts against the side wall of the damping block mounting hole 311, and the synchronous connecting shaft 323 passes through the damping spring 322 and the damping block 321 and is installed inside the synchronous sliding rail 211 of the screen support plate 2, thereby playing the effect of a sliding block; the damping pressing surface 212 of the damping block 321 presses the pressing surface 212 of the screen support plate 2, and the sliding friction force between the damping block 321 and the pressing surface 212 of the screen support plate 2 guarantees the damping effect in the movement process and the hovering effect at any position.

[0070] Similarly, the second specific embodiment of the screen support plate 2 and the folding assembly 3 is provided as follows:

[0071] On the one hand, referring to Figure 11 , Figure 14 and Figure 15 , the damping structure 32 includes the damping spring 322 and the two damping blocks 321, wherein: the two damping blocks 321 are connected to the two ends of the damping spring 322, and the two damping blocks 321 are combined to form a damping part; each damping block 321 includes a main body part 3211, an extension part 3212, and a connecting shaft 3213 protruding from the extension part 3212, and the connecting shaft 3213 forms a sliding part.

[0072] On the other hand, referring to Figure 11 , Figure 14 and Figure 15 , the synchronous support plate 31 is provided with a damping spring mounting cavity 312 for installing the damping spring 322 and a damping block mounting hole 311 for installing the damping block 321. In addition, the extension part 3212 and the connecting shaft 3213 protrude from the damping block mounting hole 311, the extension part 3212 of each damping block 321 is away from one side of the other damping block 321 to form a damping pressing surface 212A for matching the screen support plate 2, and the main body part 3211 of each damping block 321 is away from one side end face of the other damping block 321 to form a limiting surface B for matching the damping block mounting hole 311.

[0074] On the basis of any of the technical solutions in the two embodiments, as shown in the structure, Figure 7 The base assembly 1 comprises two bases 11 arranged opposite to each other in a second direction b, wherein the second direction is perpendicular to the first direction a; the two screen support plates 2 are simultaneously pivoted to the two bases 11, and the two synchronous support plates 31 are also simultaneously pivoted to the two bases 11. In combination with the structure shown in Figure 16 Each base 11 is formed with a movement sliding groove 111, and each screen support plate 2 is formed with a movement sliding rail 22 that is in sliding cooperation with the movement sliding groove 111.

[0075] It is worth noting that the cooperation of the screen support plate 2 and the base 11 with the circular arc-shaped movement sliding groove 111 can guarantee that the flexible folding screen 02 supported by the two screen support plates 2 will not be pulled during the movement of the folding hinge 01.

[0076] On the basis of the above-mentioned solution, each synchronous support plate 31 is formed with a gear part 313 that is pivoted to the base assembly 1, the self-assembly is pivoted with a gear set 4, and the gear part 313 on each synchronous support plate 31 is in gear meshing with the gears of the gear set 4.

[0077] It should be noted that the folding hinge 01 provided by the embodiment of the present application can realize the synchronous movement of the folding hinge 01 by the gear linkage between the gear part 313 on the synchronous support plate 31 and the gear set 4.

[0078] In combination with the above-mentioned structure, the movement process of each structure in the folding hinge 01 provided by the embodiment of the present application is specifically introduced as follows: the screen support plate 2 drives the synchronous connecting shaft 323 or the connecting shaft 3213 to move linearly inside the movement sliding rail 22, the synchronous connecting shaft 323 or the connecting shaft 3213 drives the damping block 321 to move, thereby driving the synchronous support plate 31 to rotate around the mounting hole on the base 11, and the gear part 313 of the synchronous support plate 31 and the gears in the gear set 4 are in mutual meshing.

[0080] Hereinafter, the working state of each structure in the electronic device 001 during folding is exemplarily introduced:

[0081] Taking the inward folding of the first shell 04 and the second shell 05 as an example, the first shell 04 and the second shell 05 are combined towards the inside, and the folding hinge 01 refers to the movement state in Figures 17-19 . Specifically, the first shell 04 and the second shell 05 drive the screen support plate 2 to move through the fastening screw, the screen support plate 2 drives the synchronous connecting shaft 323 or the connecting shaft 3213 of the synchronous support plate 31 to move in the synchronous slide rail 211 on both sides of the screen support plate 2, so that the synchronous support plate 31 rotates around the mounting hole on the base 11. The two synchronous support plates 31 are meshed with the intermediate gear set 4 through the gear, so as to ensure the synchronous movement of the first shell 04 and the second shell 05;

[0082] When the synchronous support plate 31 moves with the screen support plate 2, the synchronous connecting shaft 323 or the connecting shaft 3213 will slide from one side to the other side of the screen support plate 2, at this time, the damping block 321 sleeved in the mounting hole of the synchronous support plate 31 will be extruded by the extrusion surface 212 on both sides of the screen support plate 2, the extruded damping block 321 will move in the mounting hole of the synchronous support plate 31 away from the synchronous slide rail 211, at this time, the damping spring 322 is extruded, the pressure of the damping spring 322 increases the normal pressure between the damping block 321 and the extrusion surface 212, so that the friction between the damping extrusion surface 212 of the damping block 321 and the extrusion surface 212 of the screen support plate 2 increases, thereby achieving the hovering effect, as shown in Figures 20-21 .

[0083] When the first shell 04 and the second shell 05 complete the folding operation, the structure shown in Figure 22 is formed, correspondingly, when the first shell 04 and the second shell 05 are completely opened, the structure in Figure 1 , Figure 23 and Figure 24 is formed.

[0084] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and the equivalent technology thereof, the present application also intends to include these modifications and variations.
