Abstract: A double-shaft hinge with a single-shaft implementation mode includes a base, two shafts on the base, and a driving member for enabling the two shafts to synchronously rotate. One of the two shafts is provided with a switching member and a connecting member, the switching member is configured to drive the corresponding shaft to rotate. The switching member is limited to move between the connecting member and the base, the switching member has two first concave-convex portions positioned at two ends, the connecting member includes a second concave-convex portion which faces the switching member and can be engaged with one of the two first concave-convex portions, and the base includes a third concave-convex portion which faces the switching member and can be engaged with the other first concave-convex portion. The double-shaft hinge switches between a single-shaft implementation mode and a double-shaft implementation mode based on the switching member.

Abstract: A thinned hinge includes a rotating part and a torsion supply part. The rotating part includes a base and two movable members arranged on the base, the base includes two tracks for the movable members to displace along arc-shaped trajectories to generate opening and closing actions, and ends of the two movable members where extend outward from the two tracks are provided with driving members. The torsion supply part supplies torsion required by the rotating part, the torsion supply part includes a support, two rotating shafts arranged in parallel on the support, and an idle gear arranged between the two rotating shafts, the two rotating shafts are provided with connecting pieces assembled with the driving members to enable the torsion supply part and the rotating part to simultaneously act and gears engaged with the idle gear, and the gears and the idle gear are crossed helical gear structures.

Abstract: The invention provides a double-shaft hinge implemented with a flexible display. The double-shaft hinge includes a first shaft, a second shaft parallel to the first shaft and a shaft mounting base. The first shaft is provided with a first wheel. A first notch is formed in a periphery of the first wheel. The second shaft is provided with a second wheel. A second notch is formed in a periphery of the second wheel. Two supporting blocks are arranged at one side of the shaft mounting base facing the first wheel and the second wheel. An equal armed lever is mounted on the two supporting blocks. The equal armed lever takes the two supporting blocks as moving fulcrums. The equal armed lever selectively falls into the first notch or the second notch to switch between rotating the first shaft and rotating the second shaft.

Abstract: A thin hinge includes a rotating part including a rotating member and a support frame; and a torsion providing part. The rotating member includes a first arcuate part and a second arcuate part, the first arcuate part forms two guide slots, the frame forms two lugs disposed in the guide slots and making the first arcuate part rotatable relative to the frame, the first and second arcuate parts open and close sequentially based on a rotation angle of the rotating member. The torsion providing part includes an assembly shaft disposed on the frame, a rotating shaft assembled to the second arcuate part, and a torsion providing member connected to the rotating and assembly shafts and providing torsion for the rotating member, the torsion providing member is composed of connecting rods moving with the rotating shaft when the second arcuate part is manipulated, and driving the assembly shaft to rotate.
