Title:
JOINT ENERGY STORAGE ASSISTANCE MECHANISM, ROBOT JOINT STRUCTURE, AND ROBOT
Document Type and Number:
WIPO Patent Application WO/2022/088470
Kind Code:
A1
Abstract:
A joint energy storage assistance mechanism (100). One end of a sleeve (10) of the joint energy storage assistance mechanism serves as a first pivot end (100a); a one-way clutch rack (40) is capable of sliding axially with respect to a sliding rod (20) and one end of the one-way clutch rack (40) serves as a second pivot end (100b); an elastic structure (30) abuts between the sliding rod (20) and the sleeve (10). When a joint requires energy storage, the one-way clutch rack (40) is switched to a fixed state, the sliding rod (20) moves along with the one-way clutch rack (40), and kinetic energy of the sliding rod (20) is converted into potential energy of the elastic structure (30) to achieve energy storage. When the one-way clutch rack (40) and the sliding rod (20) return, the elastic structure (30) releases energy to drive the one-way clutch rack (40) and the sliding rod (20) to move in an opposite direction, thereby yielding a pushing assistance effect on a movable arm (300). When the one-way clutch rack (40) is switched to a free state, the one-way clutch rack (40) is capable of sliding with respect to the sliding rod (20), and the elastic structure (30) cannot achieve energy storage. The present invention also relates to a robot joint structure and a robot. Energy storage and energy release can be achieved by promptly catching and releasing the one-way clutch rack (40).
