Title:
ROTATION SHAFT STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/198743
Kind Code:
A1
Abstract:
A rotation shaft structure, comprising a center shaft (1), wherein the middle of the center shaft is provided with a one-way bearing (2) in a sleeved manner; a first damping rotation assembly and a second damping rotation assembly are respectively disposed at the left end and the right end of the center shaft (1) in a sleeving manner; and a first locking member (11) and a second locking member (12) are respectively disposed on the center shaft (1) and are located outside the first damping rotation assembly and the second damping rotation assembly. Due to the characteristics of the one-way bearing (2) itself, the one-way bearing (2) can rotate only around the center shaft (1) in one direction, and at this time, the rotation damping thereof is small and is close to zero; and when rotating around the center shaft (1) in the other direction, the one-way bearing (2) is locked, and at this time, the first damping rotation assembly and the second damping rotation assembly rotate relative to the center shaft (1) and the actual rotation damping is large. Therefore, when the one-way bearing (2) rotates around the center shaft (1) in one direction, the damping is small and close to zero, and the damping is large when the one-way bearing rotates in the other direction, thereby improving the adjustability and application range of the rotation shaft structure.
