Anti-collision early warning device of window cleaning machine

Abstract

The anti-collision early warning device is installed on a window cleaning machine body and comprises a bumper installed on the machine body, the bumper is composed of a first connecting plate and a second connecting plate, and the first connecting plate and the second connecting plate are perpendicular to each other; sliding guide wheels are fixedly installed at the lower ends of the first connecting plate and the second connecting plate, switches are arranged on the rear sides of the first connecting plate and the second connecting plate, and when the sliding guide wheels touch an obstacle, the first connecting plate and the second connecting plate are driven to move; therefore, the first connecting plate or the second connecting plate moves towards the position of the switch so as to trigger collision early warning. According to the anti-collision early warning device for the window cleaning machine, when the window cleaning machine touches an obstacle, fast feedback can be achieved, the problem that the window cleaning machine cannot make a correct judgment when meeting the obstacle is solved, and meanwhile the cleaning efficiency of an edge area is improved; through the arranged sliding guide wheels, when the window cleaning machine works at the edge position, sliding friction between the window cleaning machine and an obstacle is converted into rolling friction, the advancing resistance of the window cleaning machine is reduced, and the problem that the window cleaning machine is clamped or slips due to large friction force is avoided; by arranging the anti-falling device, the borderless glass edge can be accurately recognized, and the situation that the window cleaning machine falls from the edge and is damaged is prevented.

Description

technical field [0001] The present application relates to the technical field of window cleaning machines, and in particular, to an anti-collision warning device for window cleaning machines. Background technique [0002] Window cleaning machines mostly use vacuum adsorption to attach the machine to the window to work. When the window cleaning machine is working, it collides with obstacles. On the one hand, the window cleaning machine is damaged due to the collision; on the other hand, the collision cannot be carried out in time. Feedback, the window cleaning machine was stuck or slipped due to obstacles, resulting in the window cleaning machine not working properly. In the prior art, a method of arranging an anti-collision plate on the window-cleaning machine is generally adopted. When the window-cleaning robot collides with an obstacle, the window-cleaning machine is protected by the anti-collision plate of the window-cleaning robot, and then the window-cleaning machine is...

AI Technical Summary

Problems solved by technology

Specifically, after the collision, the window cleaning machine cannot quickly respond to obstacles through the anti-collision plate, and at the same time, due to the limitations of the anti-collision plate, it cannot clean the edge of the window, and the cleaning efficiency is low

The anti-collision plate of the window cleaning machine cannot effectively detect the low frame or the inclined frame. When the window cleaning robot climbs up the inclined frame or the low frame, it is still easy to cause the suction cup of the window cleaning robot to leak air, and the window cleaning robot is easy to cause damage and safety hazards caused by falling.

[0003] Therefore, in order to solve the problem that the window cleaning machine can respond quickly when encountering obstacles and cannot recognize the border of the frameless glass, a kind of anti-collision warning device for the window cleaning machine is needed
