Description

Technical Field

[0001] The invention relates to the technical field of window cleaning machines, and in particular to an obstacle detection structure of a window cleaning machine. Background Art

[0002] With the development of modern society, more and more people are looking to cities for work and life, which has led to an increasing population in cities and increasingly tight urban land use, which has led to higher and higher buildings in cities. Many commercial buildings now have more than 20 or 30 floors, so it is very difficult to clean high-altitude glass, and manual wiping is dangerous. Currently, window cleaning machines are often used to replace manual wiping of high-altitude glass. However, during the use of existing window cleaning machines, the window cleaning machines do not detect collisions, which causes the window cleaning work to stop when the window cleaning machine collides with the glass frame, thus affecting the normal operation of the window cleaning machine. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide an obstacle detection structure for a window cleaning machine.

[0004] One of the purposes of the present invention is achieved by the following technical solution: A barrier detection structure for a window cleaning machine comprises a rag, a protective cover is provided on the top of the rag, anti-collision wheels are provided at the four corners of the rag, a drop rod is provided through the inner cavity of the anti-collision wheel, a reset spring is provided on the drop rod, a rocker arm is provided on the top of the anti-collision wheel, a light-sensing lever is provided on the top of the rocker arm, a first micro switch and a second micro switch are provided on the left and right sides of the rocker arm respectively, a connecting cover is provided on the top of the rocker arm, two metal shrapnels are provided on the connecting cover, the two metal shrapnels are matched with the first micro switch and the second micro switch respectively, and a silicone gasket is provided on one side of the first micro switch and the second micro switch.

[0005] Preferably, a handle is provided on the top of the protective cover, and a power cord is provided on the front side of the protective cover.

[0006] Preferably, water tanks are plugged into the top of the protective cover near the left and right sides.

[0007] Preferably, the first micro switch and the second micro switch have the same structure, and the first micro switch and the second micro switch are symmetrically arranged with the central axis of the rocker as the axis of symmetry.

[0008] Preferably, the four anti-collision wheels are arranged in a rectangular array.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides an obstacle detection structure for a window cleaning machine. After the window cleaning machine touches an edge, the anti-collision wheel is impacted to push the swing rod to move and simultaneously push the first micro switch or the second micro switch. The first micro switch or the second micro switch generates an electrical signal and sends it to the main control circuit board to avoid obstacles. 2. The obstacle detection structure of a window cleaning machine of the present invention is that when the window cleaning machine moves to the edge, the drop rod moves downward under the action of the reset spring, driving the light sensing lever to move to produce light changes, so that the photoelectric sensor generates an electrical signal and sends it to the main control circuit to avoid obstacles; 3. In an obstacle detection structure of a window cleaning machine of the present invention, two metal springs are respectively used for resetting the first microswitch and the second microswitch to ensure the subsequent normal operation of the first microswitch and the second microswitch. During use, the silicone gasket plays a buffering and resetting role for the first microswitch and the second microswitch.

[0010] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following specifically cites a preferred embodiment and describes it in detail with the accompanying drawings as follows.
