Title:
HIP MECHANISM AND PORTABLE POWER-ASSIST DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/191802
Kind Code:
A1
Abstract:
Provided are a hip mechanism and a portable power-assist device, wherein, the hip mechanism (23) includes an upper hip arm (2311), a lower hip arm (232), a first pulley (2312) and a second pulley (2313); the lower hip arm (232) and the upper hip arm (2311) are rotationally connected; the first pulley (2312) is rotatably mounted on the upper hip arm (2311); the second pulley (2313) is rotatably mounted on the upper hip arm (2311); wherein, when a cable (12) is arranged, the cable (12) is introduced from the upper hip arm (2311) and passes around the first pulley (2312), leaves the first pulley (2312) in a tangential direction and then gets into the second pulley (2313) in a tangential direction, after passing around the second pulley (2313), the cable (12) leaves the second pulley (2313) in a tangential direction, and is derived from the lower hip arm (232) to bend the cable (12) into an "S" shape, when the cable (12) performs the tightening action, the cable (12) applies force to the upper hip arm (2311) and the lower hip arm (232), such that the upper hip arm (2311) and the lower hip arm (232) relatively rotate. The hip mechanism can increase the transmission speed of the cable, reduce the wear of the cable, and increase the life of the cable.
