Title:
DISTANCE MEASURING DEVICE AND SWEEPING ROBOT
Document Type and Number:
WIPO Patent Application WO/2021/128404
Kind Code:
A1
Abstract:
A distance measuring device and a sweeping robot. The distance measuring device comprises: a base (100) comprising a base plate (110) and a side wall (120) obtained by extending from the base plate (110); a baffle (200) disposed opposite to the base plate (110); a first transmission wheel (300) and a second transmission wheel (400) both rotatably installed on the base (100); a connecting member (500) wound around the first transmission wheel (300) and the second transmission wheel (400), and used for driving the second transmission wheel (400) to rotate when the first transmission wheel (300) rotates; and a driving device (600) used for driving the first transmission wheel (300) to rotate. The side wall (120) at least partially surrounds the periphery of the first transmission wheel (300). The baffle (200) is attached to the portion of the side wall (120) surrounding the periphery of the first transmission wheel (300). The base plate (110), the baffle (200), the side wall (120) and the second transmission wheel (400) together define a first mounting chamber. The first transmission wheel (300) is accommodated in the mounting chamber. Therefore, impurities can hardly enter the mounting chamber to wind around the first transmission wheel (300), thereby avoiding the technical problem of jamming of a driving wheel due to that the driving wheel is directly wound by the impurities.
