Document Type and Number:
WIPO Patent Application WO/2022/217861
Kind Code:
A1
Abstract:
A robot chassis and an intelligent cleaning robot. The robot chassis comprises: a main body (100); driving units (200), which are arranged on two sides of the main body (100), wherein each driving unit (200) comprises a driving electric motor (210), and a front driving wheel (220) and a rear driving wheel (230) which are driven by the driving electric motor (210) to operate; and a driven wheel (300), which is arranged at the bottom of the main body (100). The driven wheel (300), the front driving wheels (220) and the rear driving wheels (230) are sequentially arranged at the bottom of the main body (100) from front to back, and when the robot chassis moves on flat ground, the bottom of each rear driving wheel (230) is not lower than the bottom of each front driving wheel (220). The robot chassis uses the driving units (200), which are arranged independent of each other; each driving unit (200) comprises the front driving wheel (220) for driving the robot to move and the rear driving wheel (230) for assisting the robot in crossing obstacles; and each rear driving wheel (230) assists in supporting the robot during the crossing of obstacles, and provides an upward and forward driving force, such that the obstacle crossing capability of the cleaning robot is improved.
