Title:
HINGE MECHANISM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/055889
Kind Code:
A1
Abstract:
A hinge mechanism and an electronic device. In the hinge mechanism, a first rotating member (210) and a second rotating member (220) are respectively arranged on two opposite sides of a mounting assembly, the mounting assembly comprises a mounting base (110) and a synchronization member (120) arranged on one surface of the mounting base (110), and the synchronization member (120) is in movable fit with the mounting base (110) in the lengthwise direction of the mounting base (110); and the synchronization member (120) is provided with a first limiting groove (121a) and a second limiting groove (122a), a first rotating arm (212) and a second rotating arm (222) are both in rotational fit with the mounting base (110) in a direction around the lengthwise direction, a first driving arm (213) and a second driving arm (223) both spirally extend around the length direction, the directions of rotation of the first driving arm and the second driving arm are opposite to each other, the first driving arm (213) is in sliding fit with the first limiting groove (121a), and the second driving arm (223) is in sliding fit with the second limiting groove (122a). Under the condition that the first rotating member (210) rotates relative to the mounting base (110) in a first rotation direction, the first driving arm (213) drives the synchronization member (120) to move relative to the mounting base (110) in the length direction and the synchronization member (120) drives the second driving arm (223) to rotate relative to the mounting base (110) in a second rotation direction, the second rotation direction being opposite the first rotation direction.
