Description

TECHNICAL FIELD

The present disclosure relates to the technical field of swimming pool robots, specifically relates to a waterproof sealing mechanism for motor cable of swimming pool robots.

BACKGROUND ART

The swimming pool cleaning robots are automatic device capable of autonomously finishing the cleaning work of the pool bottom under water. It can help people easily clean up daily garbage and dirt at the bottom of swimming pool, completely changing the previous manual cleaning way, so that the cleaning work becomes no longer troublesome. In order to realize the function of autonomously cleaning under water, in addition to good water-proof performance, the robot also needs a pair of “eyes” capable of route recognition, and this pair of eyes are path navigation systems thereof. Generally, such kind of navigation system uses a measurement manner in which an acceleration sensor and a gyroscope are combined to acquire a trajectory of a moving object, so as to control the movement trend thereof.

In order to realize the function of autonomously cleaning under water, the robot should not only have its own path navigation system, but also have good waterproof performance. The motor mounting base used by the existing swimming pool robot is generally sealed by sealing ring between the motor and the mounting base; however, the sealing of motor leads is performed by splicing two pieces of flexible materials provided with wire holes, but the sealing position is not tight enough, which probably causes leakage, thereby causing damage to the swimming pool robots.
