Document Type and Number:
WIPO Patent Application WO/2024/037140
Kind Code:
A1
Abstract:
Provided in the present application is a hinge device, which comprises a hinge assembly, a torsion assembly and an elastic assembly. A rotating assembly comprises a first base and a rotating member, the rotating member being rotationally connected to the first base, and the rotating member comprising a first cam. The torsion assembly comprises a hinge and a hinge mounting member, the axis of the hinge being parallel to the rotation axis between the rotating member and the first base, the hinge mounting member being slidably sleeved on the hinge in the axial direction of the hinge, and the hinge mounting member comprising a first abutting cam. The elastic assembly comprises a first elastic member, two opposite ends of the hinge mounting member respectively abutting against the first elastic member and the rotating member, and the first elastic member abutting against and pushing the hinge mounting member so as to enable the first abutting cam and the first cam to rotationally abut against each other. When the rotating member rotates relative to the hinge mounting member, the first cam rotationally abuts against the first abutting cam, and the rotation of the rotating member is limited by means of the friction torsion between the first cam and the first abutting cam. Also provided in the present application are a folding housing provided with the hinge device and an electronic apparatus.
