Title: SURFACE CLEANING ROBOT AND PROCESS FOR MANUFACTURING TRACK THEREOF
Abstract:
Disclosed are a surface cleaning robot (100) and a process for manufacturing a track (143) thereof. The surface cleaning robot (100) comprises a body (110). The bottom of the body (110) is provided with travelling portions (140). The travelling portion (140) comprises a track (143) and a gear (142) for driving the track (143) to rotate. The track (143) comprises a hard layer (1430) located on an inner ring and engaged with the gear (142), and a soft layer (1433) located on an outer ring and being in contact with a surface to be cleaned. The hard layer (1430) and the soft layer (1433) are combined as a whole in a nested manner. The composite track (143) using a nested combination tightly combines the inner and outer rings of different materials. The process is simple, but improves the integral strength and toughness of the track (143) and solves the problem that the track (143) has a poor running capability on the surface to be cleaned, thereby enhancing the working safety of the surface cleaning robot (100) and reducing the production cost. The surface cleaning robot has a simple structure, is convenient to manufacture, has a wide range of application and also has the advantage of synchronous belts, so that the cleaning efficiency and service life of the surface cleaning robot (100) are increased.
