Description

Technical Field

[0001] The utility model relates to the technical field of sweeping robots, in particular to a sweeping robot with universal wheels and stable walking. Background Art

[0002] With the rapid development of smart home appliances, more and more smart electronic products have entered our lives. Automatic sweeping robots are one of them. Due to the continuous upgrading of their artificial intelligence and increasingly powerful functions, they clean the ground more and more cleanly and quickly, reducing people's labor intensity and saving labor time. Some existing sweeping robots or floor scrubbers are equipped with front universal wheels. When the machine is cleaning hard particles, the universal wheels will shake, bump, and the universal wheels will slip and idle when passing over particles and other garbage. This will cause the machine to shake, bump, walk unsteadily, deviate from the route, and have low walking efficiency. The shaking and bumping of the machine will make it difficult for the roller brush at the rear end of the universal wheel to stay close to the ground during cleaning, which will lead to problems such as unclean cleaning and low cleaning efficiency, resulting in a poor user experience.
