Title:
AUTONOMOUS MOBILE ROBOT, AND SYNCHRONOUS BELT AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/179933
Kind Code:
A1
Abstract:
Disclosed are an autonomous mobile robot, and a synchronous belt and a preparation method therefor. The autonomous mobile robot comprises a machine body, with a synchronous belt (1) being arranged at the bottom of the machine body. The synchronous belt (1) comprises an inner ring (2) and an outer ring (3), wherein the outer ring (3) is in rolling contact with a travelling surface; the inner ring (2) and the outer ring (3) are both made of millable polyurethane; the shore hardness of the inner ring (2) is 60A-90A; and the shore hardness of the outer ring (3) is 30A-60A. The synchronous belt of the autonomous mobile robot has a good wear resistance, can maintain high abradability where the hardness is low, can effectively improve the friction force between the autonomous mobile robot and working media such as glass, improves the working efficiency and the range of cleaning of the autonomous mobile robot, and expands the use range of the autonomous mobile robot.
