Lifting assembly, cleaning mechanism and cleaning robot

Abstract

The invention relates to a lifting assembly, a cleaning mechanism and a cleaning robot, the lifting assembly is used for lifting a tray of the cleaning robot, and the lifting assembly comprises a transmission part, a supporting part and a first driving device. The transmission part comprises a connecting end and a matching end distributed at the two ends of the transmission part and is connected with the tray through the connecting end. The supporting part is used for supporting the transmission part, and the connecting end and the matching end are distributed on different sides of the supporting part. The first driving device is used for driving the matching end to move, and the connecting end can move from the first position to the second position. The transmission part and the supporting part form a simple lever device, and the connecting end can move from the first position to the second position by means of the simple lever principle. The structure is simpler, and the occupied space is smaller. The cleaning robot applying the lifting assembly has the capability of quickly moving the tray from the position in contact with the working surface to the position far away from the working surface.

Description

technical field [0001] The invention relates to the technical field of working face cleaning, in particular to a lifting assembly, a cleaning mechanism and a cleaning robot. Background technique [0002] With the development of technology and the needs of people's home life, various intelligent robots are rapidly rushing to the market and penetrating into the lives of users. The cleaning robot is a typical representative thereof, which has the functions of sweeping, sucking, mopping, and washing either singly or in combination. [0003] In order to realize the cleaning function and ensure the cleaning effect of the cleaning robot, when it performs cleaning operations, the cleaning parts on the chassis must be close to the ground. However, obstacles such as wires, carpets, and anti-slip mats are usually unavoidable in its working environment. When the cleaning robot tries to pass through these obstacles, the cleaning parts on the chassis of the cleaning robot may be stuck by...

AI Technical Summary

Problems solved by technology

However, obstacles such as wires, carpets, and non-slip mats are usually unavoidable in its working environment. When the cleaning robot tries to pass through these obstacles, the cleaning parts on the chassis of the cleaning robot have the risk of being stuck by the obstacles.

[0004] In order to overcome this defect, the cleaning robots in the prior art generally realize the active lifting of the cleaning parts through components such as worm gears, worms, and drive motors, but this type of structure is complex and takes up a lot of space.
