WIPO Patent Application WO/2021/018234
Kind Code:
A1
Abstract:
A sweeping robot comprising: a main body (10) and driving wheels (20), the driving wheels (20) are provided at side edges of the main body (10) and used for driving the main body (10) to move, each of the driving wheels (20) comprises: an inner hub assembly (300), connected to the main body (10) and internally provided with a drive member (310) and a transmission member (320); and an outer hub assembly (400), provided in the outside of the inner hub assembly (300) and rotatably connected to the inner hub assembly (300), one end of the transmission member (320) is in transmission connection with the drive member (310), the other end is in transmission connection with the outer hub assembly (400), and the drive member (310) transmits a torsion force to the outer hub assembly (400) by means of the transmission member (320), such that the outer hub assembly (400) is able to rotate relative to the inner hub assembly (300) and the main body (10), thereby driving the robot to move. In the sweeping robot, the driving wheels (20) are provided at side edges of the main body (10), such that the driving member (310) does not occupy the space of the main body (10); and the driving member (310) and the transmission member (320) are provided within the driving wheels (20), such that the overall structure of the robot is compact, and the overall volume is small.
