Document Type and Number:
WIPO Patent Application WO/2021/143167
Kind Code:
A1
Abstract:
A rotation mechanism and a mobile terminal, used to achieve stable rotation. The rotation mechanism comprises a first rotating shaft (1), a second rotating shaft (2), a first link rod (7), a second link rod (8), and a third link rod (9). Two ends of the first link rod (7) are provided with a first terminal portion structure (14). Two ends of the second link rod (8) are provided with a second terminal portion structure (15). Two ends of the third link rod (9) are provided with a third terminal portion structure (16). The first rotating shaft (1) passes through the first terminal portion structure (14) and the second terminal portion structure (15). The second rotating shaft (2) passes through the second terminal portion structure (15) and the third terminal portion structure (16). After the first terminal portion structure (14) and the second terminal portion structure (15) rotate in opposite directions, side surfaces of the first link rod (7) and the second link rod (8) close to a target side (21) form an arched curved surface. After the second terminal portion structure (15) and the third terminal portion structure (16) rotate in opposite directions, side surfaces of the second link rod (8) and the third link rod (9) close to the target side (21) form an arched curved surface. In this way, the invention enables stable relative rotation between the first link rod (7) and the second link rod (8) and stable relative rotation between the second link rod (8) and the third link rod (9).
