Title:
JOINT INTERNAL WIRING STRUCTURE, JOINT MECHANISM AND FOOT-TYPE ROBOT
Document Type and Number:
WIPO Patent Application WO/2023/071150
Kind Code:
A1
Abstract:
A joint internal wiring structure. A first coiling body (3) and a second coiling body (5) which are rotatable relative to one another are provided at a joint, and a cable (4) is wound by means of a winding part (7) of the second coiling body (5) to achieve the adjustment of the length of the cable (4), so that the length of the wound cable (4) may be changed along with the expansion amplitude of the joint, which can effectively reduce the irregular stacking of the cable (4), and effectively ensure that the cable (4) is always kept neat and not clamped in the reciprocating rotation process. Therefore, interference between the cable (4) and other joint components is effectively avoided, and the solution is simple, practical and feasible. Meanwhile, an accommodating cavity (8) is provided on the first coiling body (3), so that the movement range of the cable (4) can be effectively limited while the cable (4) is protected, and the cable (4) interfering with joint movement causing potential safety hazards and causing wear of other components of the joint is further avoided. Further provided are a joint mechanism and a foot-type robot.
