Description

Running gear, floor brush subassembly and cleaning device Technical Field The application relates to the technical field of cleaning equipment, in particular to a traveling device, a floor brush assembly and cleaning equipment. Background Along with the development of science and technology and the improvement of life quality of people, cleaning equipment is increasingly applied to life of people. The cleaning device comprises a sweeping robot, a handheld floor washing machine and the like. Taking a hand-held cleaning device as an example, a user may perform a push-forward or pull-back operation to perform cleaning, while the hand-held cleaning device is generally heavy and the user may have a lot of effort to perform the push-forward or pull-back operation. In the related art, the movement of the cleaning device is assisted by integrating the hub motor on the traveling wheel of the cleaning device, however, the hub motor and the matched control system have higher cost, resulting in a significant increase in the manufacturing cost of the cleaning device. Disclosure of Invention The application provides a walking device, a floor brush assembly and cleaning equipment, which are beneficial to reducing the manufacturing cost of the cleaning equipment. The application provides a traveling device which comprises a wheel shaft, an elastic force storage piece, a traveling component and a buffering piece, wherein the elastic force storage piece is provided with a first connecting end and a second connecting end, the first connecting end is arranged on the wheel shaft, the traveling component is rotatably arranged on the wheel shaft and comprises a traveling wheel body and the buffering piece which are relatively fixed, the buffering piece is located between the elastic force storage piece and the traveling wheel body, the second connecting end is in contact with the buffering piece, the traveling component rotates in a first direction to enable the elastic force storage piece to store force, and when the traveling component rotates in the reverse direction of the first direction, the elastic force storage piece releases elastic force to assist the traveling component to rotate in the reverse direction of the first direction. According to the running gear disclosed by the embodiment of the application, the elastic force storage piece is arranged, the first connecting end of the elastic force storage piece is connected with the wheel shaft, the second connecting end is in contact with the buffer piece, so that when the running wheel body which is relatively fixed with the buffer piece rotates along the first direction, the elastic force storage piece can store force, and when the running part rotates reversely along the first direction, the elastic force storage piece can release the stored elastic force to assist the running part to rotate reversely along the first direction, so that assistance can be provided for a user when the user uses the cleaning equipment, the labor saving degree and the user experience of the cleaning equipment can be improved, and the use of a hub motor can be avoided, so that the manufacturing cost of the running gear can be reduced.
