Abstract

A robot cleaner includes a main body, drive motors provided on the main body, each of the drive motors including a drive rotary shaft, drive wheels rotated by rotary force transmitted from the drive motors, gear units connecting the drive motors and the drive wheels, and wheel cover housings to support the drive wheels so that the drive wheels are pivotally rotated with respect to the main body, and pivot rotary shafts of the drive wheels and drive rotary shafts of the drive motors are coaxial with each other so as to achieve stable movement of the drive wheels.

Description

technical field [0001] Embodiments of the present disclosure relate to a robot cleaner in which a driving wheel can both rotate about its center axis and pivot about a pivot axis to move up or down. Background technique [0002] Generally, a robot cleaner sucks external substances such as dust from a floor in an area to be cleaned while spontaneously traveling the area to be cleaned, thereby performing a cleaning operation. A robot vacuum cleaner generally includes a drive unit and a cleaning unit. [0003] The driving device of the robot vacuum cleaner includes: a pair of driving wheels provided at the lower part of the main body of the robot vacuum cleaner; a pair of driving motors for supplying driving power to the driving wheels; a battery for supplying power to the driving motors; various sensors and control units, Used to control the drive wheels. The cleaning unit of the robot vacuum cleaner consists of brushes, suction fan, filter and dust collection tray. [0004...
