Abstract

The invention discloses a motor assembly and a sweeping robot. The motor assembly comprises a shell; a motor and a reduction gearbox are both arranged in the shell. The reduction gearbox comprises a box body, a speed reduction mechanism, a limiting shaft, an output shaft and an axial limiting mechanism, the speed reduction mechanism is connected with the rotating shaft and the output shaft, the limiting shaft is connected with the speed reduction mechanism, and the axial limiting mechanism is arranged on the side wall of the output shaft in a sleeving mode and abuts against the speed reduction mechanism and the box body; a first end cover is arranged at one end of the motor away from the reduction gearbox to seal one end opening of the shell; a second end cover is arranged at the end, away from the motor, of the reduction gearbox and fixedly connected with the box body and the shell to seal an opening in the other end of the shell. The axial supporting piece comprises an inner ring and an outer ring which are rotatably connected, the inner ring sleeves the outer wall of the first end cover, and the outer ring abuts against the inner wall of a roller; the fixing piece is fixedly connected with the roller and rotationally connected with the first end cover. According to the technical scheme, the service life of the motor assembly is prolonged.

Description

technical field [0001] The invention relates to the technical field of sweeping robots, in particular to a motor assembly and a sweeping robot using the same. Background technique [0002] Sweeping robots can replace people to quickly clean the ground, which can effectively relieve people's cleaning pressure and are very popular. The cleaning robot in the related art uses a drum motor as a driving part of the cleaning robot. The driving components include a motor and a reduction box, etc., and both the motor and the reduction box need to cooperate with the drum, so that the belt drum rolls relative to the sweeping robot, so as to drive the brush on the outside of the drum for cleaning operations. The stability of the operation of the drive components directly affects the cleaning effect and service life of the sweeping robot. In addition, there is a lot of dust and accumulated water in the working environment of the sweeping robot, the working environment is harsh, and the...
