TRANSMISSION DEVICE, AUTOMATIC CLEANING DEVICE AND ROBOT CLEANING SYSTEM

Abstract

The invention relates to a transmission device, an automatic cleaning apparatus, and a cleaning robot system. The transmission device is used in the automatic cleaning apparatus, which comprises a main machine body and a first cleaning element. The transmission device includes a first drive assembly (131), a pivoting arm (1313), and an elastic element (1317). The pivoting arm is rotationally connected to the main body. The first end of the elastic element (1317) is connected to the pivoting arm, and the second end of the elastic element is fixed relative to the main body. The first cleaning element is arranged on the pivoting arm, and the first drive assembly, in combination with the elastic element (1317), is used to rotate the pivoting arm, thus enabling the first cleaning element to be moved between a first and a second operating position.
