Title:
ROTATING SHAFT MECHANISM AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/199493
Kind Code:
A1
Abstract:
A rotating shaft mechanism (10) and a terminal device comprising the rotating shaft mechanism (10). The rotating shaft mechanism (10) comprises a main shaft assembly (102) and a damping assembly (101); the damping assembly (101) is rotatably connected to the main shaft assembly (102); the damping assembly (101) may comprise a cam member (1011) and a rotating assembly (1012); the cam member (1011) is fixed to the main shaft assembly (102); the cam member (1011) has a cam surface (10111); the rotating assembly (1012) comprises a rotating member (10121) and a sliding member (10122); the rotating member (10121) is rotatably connected to the main shaft assembly (102); the sliding member (10122) can slide with respect to the rotating member (10121) in a direction toward or away from the main shaft assembly (102); the sliding member (10122) elastically abuts against the cam surface (10111); the abutting force formed by the elastic abutment can be converted into a resistance to relative rotation of the cam member (1011) and the rotating assembly (1012), so as to generate a damping force between the main shaft assembly (102) and the damping assembly (101), and provide a sufficient supporting force for a terminal device when the terminal device is in an unfolded state.
