Document Type and Number:
WIPO Patent Application WO/2022/077801
Kind Code:
A1
Abstract:
Provided is a universal drive structure, comprising a base (1), a linkage assembly (200) mounted on the surface of the base (100), a drive assembly (300) mounted on the base (100) and drive-connected the linkage assembly (200), and a propulsion assembly (400) located on one side of the base (100) and used for driving the the base (100); the linkage assembly (200) comprises an input support base (210) and output support base (220) mounted on the surface of the base (100), an input shaft (230) mounted on the input support base (210), and an output shaft (240) mounted on the output support base (220); a universal joint connector (250) is arranged between the input shaft (230) and the output shaft (240); the end of the output shaft (240) away from the universal joint connector (250) is connected to a universal wrench (260). Using the floating structure in conjunction with the universal wrench for driving, it is possible to achieve drive within a certain range of tolerance and drive performance is good, and the invention has a broad range of applications and high structural reliability.
