Title:
COLLISION MECHANISM AND FLOOR MOPPING MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/077997
Kind Code:
A1
Abstract:
A collision mechanism and a floor mopping machine. The collision mechanism is provided on an inner casing (4) of a cleaning appliance and comprises a collision plate (1), an elastic device (2), and an induction device (3); the elastic device (2) is provided for maintaining a movable gap between the collision plate (1) and the inner casing (4); when the collision plate (1) hits an obstacle, the collision plate (1) is forced to drive the elastic device (2) to compress or stretch, so that the collision plate (1) is displaced, and a signal is generated by touching the induction device (3); when the horizontal or vertical component force of a certain collision position is small, the restriction on the collision plate (1) is elastic without any rigid restriction due to the configuration of the elastic device (2), so that the collision plate (1) can be displaced after overcoming the spring force of a spring (211), thereby triggering a plurality of sensors (31); and as the elastic device (2) is provided, different sensors (31) are triggered when different positions of the collision plate (1) are impacted, so that a control system can correctly determine the collision position and make a corresponding adjustment.
