Motor box and cleaning robot

Abstract

The motor box and cleaning robot provided by the present disclosure comprise a detachably connected upper cover and lower cover and a multiple sealing structure; the upper cover is provided with a conductive pin for signal transmission, the conductive pin is integrally formed with the upper cover through injection molding, and the outer periphery of the conductive pin is provided with a waterproof cover; the multiple sealing structure comprises at least a first-stage sealing structure and a second-stage sealing structure, the first-stage sealing structure is arranged at the joint of the upper cover and the lower cover, and the second-stage sealing structure is embedded between the waterproof cover and the upper cover. The motor box and cleaning robot of the present disclosure form double protection through the first-stage sealing structure and the second-stage sealing structure, and cooperate with the injection molding integrated design of the conductive pin and the upper cover to solve the problem of water vapor intrusion, and can maintain long-term sealing reliability underwater; the detachable connection design of the upper cover and the lower cover makes the motor and circuit components in the motor box convenient to overhaul and replace.
