In this embodiment, the limiting component includes a avoidance groove 341 disposed on a part of the rotation circumference of the second rotating member 332, and a limiting block 342 corresponding to the avoidance groove 341.

The folding hinge 3 in this embodiment has a first state (as shown in fig. 8) in which the rotational circumferential surface of the second turning member 332 abuts against the stopper 342 and the elastic pushing force is offset, and a second state (as shown in fig. 6) in which the elastic pushing force is released while the clearance groove 341 and the stopper 342 are opposed to each other.

Further, based on that the movement between the first housing 1, the second housing 2 and the folding hinge 3 is also limited by the flexible screen provided thereon in the folding apparatus, it should be understood by those skilled in the art that, although in the second state, the clearance groove 341 and the stopper 342 are opposed such that a gap is generated between the second rotating member 332 and the stopper 342, it does not mean that the second rotating member 332 is necessarily pushed by the elastic pushing force of the first elastic member 323 until the gap disappears, but is limited by the flexible screen: when the folding apparatus is unfolded, if the flexible screen is slightly loosened, the second rotating member 332 is pushed by the elastic pushing force of the first elastic member 323 until the flexible screen is stretched; when the folding apparatus is flattened, if the flexible screen is only slightly creased, the second rotating member 332 may not be actually pushed, but merely improve the creasing problem because of the tendency to be pushed.

In some embodiments, to further increase the torsion force during the relative rotation flattening or folding of the first rotating member 331 and the second rotating member 332, and to improve the hovering stability of the folding terminal, as shown in fig. 2 and 9, the folding hinge 3 may be provided with at least one damping assembly 36, where the damping assembly 36 includes a first concave-convex member 361, a second concave-convex member 362, a locking block 363, and a second elastic member 364, where the first concave-convex member 361 and the second concave-convex member 362 are matched and fit over the same gear shaft in the synchronous gear set, and the gear shaft can rotate in the first concave-convex member 361, and the second concave-convex member 362 rotates synchronously with the gear shaft; the first concave-convex member 361 and the second concave-convex member 362 are respectively provided with a first concave-convex structure and a second concave-convex structure, and the second concave-convex member 362 can slide along the axial direction of the gear shaft along with the engagement or the separation of the first concave-convex structure and the second concave-convex structure; the locking block 363 is locked outside the gear shaft, and the gear shaft can rotate in the locking block 363; both ends of the second elastic member 364 are respectively abutted against the second concave-convex member 362 and the locking block 363. In particular, the second elastic member 364 may be a spring.

Specifically, when the damping assemblies 36 are disposed corresponding to the gear shafts in the synchronous gear set, in a specific implementation, one damping assembly 36 may be disposed on each gear shaft, or the damping assemblies 36 may be disposed on a part of the gear shafts, for example, when the synchronous gear set includes four gears of the first gear 351 to the fourth gear 354 shown in fig. 9, the damping assemblies 36 may be disposed only on the gear shafts of the first gear 351 and the second gear 352.

Specifically, when the folding hinge 3 further includes two or more damping members 36, two or more locking pieces 363 may be fixed to each other by providing two or more first concave-convex pieces 361 fixed to each other.

Specifically, the first concave-convex structure and the second concave-convex structure may be disposed, so that when the first rotating member 331 and the second rotating member 332 are relatively flattened to the maximum angle, the convex portion on the first concave-convex structure is engaged with the concave portion on the second concave-convex structure, thereby forming self-locking. In addition, a plurality of protruding portions on the first concave-convex structure and/or a plurality of recessed portions on the second concave-convex structure may be further provided, so that the first rotating member 331 and the second rotating member 332 can form self-locking when being relatively flattened (or folded) to one or more intermediate angles (such as an angle between the first rotating member 331 and the second rotating member 332 is 30 degrees, 90 degrees, 120 degrees, etc.), which is convenient for users to use.

Specifically, the maximum angle may be set to 180 degrees.

In the folding apparatus of this embodiment, by disposing the avoidance groove 341 on a part of the rotation circumference of the second rotating member 332 in the folding hinge 3, and disposing the stopper 342 corresponding to the avoidance groove 341, disposing the folding hinge 3 further including the first elastic member 323 whose two ends abut against the first connecting member 321 and the second connecting member 322, respectively, the first rotating member 331 rotatably connected to the first connecting member 321, and the second rotating member 332 rotatably connected to the second connecting member 322, so that the folding hinge 3 has the first state (for example, when the angle between the first rotating member 331 and the second rotating member 332 is between 0 ° and 135 °) when the elastic thrust of the first elastic member 323 is cancelled, and the second state (for example, when the angle between the first rotating member 331 and the second rotating member 332 is between 180 °) when the elastic thrust is released, tending to push (or a very small push is actually generated) the second rotating member 332 away from the first rotating member 331; that is, the flexible screen in the folding terminal is allowed to be stretched by the movement tendency (or the movement of a very small magnitude actually generated) of the second rotating member 332 when unfolded (when the folding hinge 3 is in the second state), so that the display screen of the flexible display screen is flattened.

While obvious variations or modifications are contemplated as falling within the scope of the present utility model.
