Title:
LIFTING/LOWERING APPARATUS AND CLEANING ROBOT
Document Type and Number:
WIPO Patent Application WO/2022/166020
Kind Code:
A1
Abstract:
A lifting/lowering apparatus (100) and a cleaning robot (1000). The lifting/lowering apparatus (100) comprises a housing (10), a driving mechanism (20), and a lifting/lowering mechanism. The driving mechanism (20) is provided within the housing (10). The lifting/lowering mechanism is provided within the housing (10). The lifting/lowering mechanism comprises a rotating member (31), a lifting/lowering rod (32), and a flexible block (33). The driving mechanism (20) is connected to the rotating member (31) to drive the rotating member (31) to rotate. The lifting/lowering rod (32) is connected to the rotating member (31) and is capable of moving up and down with the rotation of the rotating member (31). The flexible block (33) is connected to the top section of the lifting/lowering rod (32). The flexible block (33) is configured as being capable of extending beyond the housing (10) and driving a roller brush component (800) of the cleaning robot (1000) to be raised or lowered. The lifting/lowering apparatus (100) is capable of driving the roller brush component (800) of the cleaning robot (1000) to move up and down, thus preventing the roller brush component (800) from coming into contact with a puddle on the ground surface, and solving the problem of mutual interference between sweeping and mopping functions in the prior art.
