Description

Technical Field

[0001] The utility model relates to the technical field of window cleaning machines, in particular to an anti-collision and anti-fall detection mechanism. Background Art

[0002] A window-cleaning robot, also known as an automatic window cleaner, glass-cleaning robot, smart window cleaner, or intelligent window cleaner, is a type of smart home appliance. It uses a vacuum pump or fan mechanism on its base to firmly adhere to the glass. Using artificial intelligence, it automatically detects the window's corners and calculates a cleaning path. Window-cleaning robots typically use the force of their adhesion to drive a cloth at their base to remove dirt, solving the problem of high-rise and outdoor window cleaning.

[0003] With the development of technology, in order to prevent window cleaning machines from colliding and falling, existing window cleaning machines are equipped with anti-collision and anti-fall detection mechanisms. However, the existing window cleaning machines have relatively complex anti-collision and anti-fall detection methods and the production cost is too high. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide an anti-collision and anti-fall detection mechanism.

[0005] One of the purposes of this utility model is achieved by the following technical solution:

[0006] The anti-collision and anti-fall detection mechanism includes a window cleaning machine base plate, a window cleaning machine upper shell is provided on the top of the window cleaning machine base plate, and anti-collision component brackets are inserted near the four corners of the bottom of the window cleaning machine base plate. A bearing is sleeved on the anti-collision component bracket, and a bearing sleeve is sleeved on the outer edge of the bearing. A drop rod is passed through the inner cavity of the anti-collision component bracket, a switch lever is provided on the top of the anti-collision component bracket, and a light sensing module component is provided on the side wall of the switch lever.

[0007] Furthermore, the four anti-collision component brackets are arranged in a rectangular array at the bottom of the window cleaning machine base plate.

[0008] Furthermore, an anti-collision component reset spring is provided on the side wall of the anti-collision component bracket, and the anti-collision component bracket and the anti-collision component reset spring match each other.

[0009] Furthermore, the outer edge of the drop rod is sleeved with a drop rod reset spring, and the drop rod and the drop rod reset spring match each other.

[0010] Furthermore, the bottom end of the drop rod is flush with the bottom end of the bearing sleeve.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The anti-collision and anti-fall detection mechanism of this utility model has collision detection and anti-fall detection functions, reducing the risk of safety accidents when cleaning windows;

[0013] 2. The anti-collision and anti-fall detection mechanism of the present invention, during the collision detection process, for the use scenario of wiping doors and windows with frame, because the diameter of the bearing sleeve is slightly larger than the diameter of the machine body, when the machine travels to the edge of the door or window and collides with the frame, the bearing sleeve will collide with the frame before the machine body. In addition, the bearing sleeve is connected to the anti-collision component bracket through the bearing. Under the action of the collision force, the bearing drives the switch lever to move. The other end of the switch lever blocks the light sensing module component, causing the light to change, thereby generating an electrical signal. The PCB transmits the electrical signal to the main control unit of the window cleaning machine, changing the driving trajectory, and ultimately achieving collision detection;

[0014] 3. The anti-collision and anti-drop detection mechanism of the utility model, during the anti-drop detection process, for the use scenario of wiping frameless doors and windows, under the weight of the machine body, the drop rod is compressed and shortened. When the machine travels to the edge of the door and window, the drop rod exceeds the edge of the door and window before the machine body. After losing the pressure of its own weight, the drop rod is slightly popped out under the elastic potential energy of the drop rod reset spring. The drop rod drives the switch lever to block the light sensing module component, causing the light to change, thereby generating an electrical signal. The PCB transmits the electrical signal to the main control unit of the window cleaning machine, changes the driving trajectory, and finally realizes anti-drop detection.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The utility model provides a technical solution: an anti-collision and anti-fall detection mechanism, including a window cleaning machine bottom plate 1, a window cleaning machine upper shell 2 is provided on the top of the window cleaning machine bottom plate 1, and an anti-collision component bracket 5 is plugged into the four corners of the bottom of the window cleaning machine bottom plate 1. An anti-collision component return spring 7 is provided on the side wall of the anti-collision component bracket 5, and the anti-collision component return spring 7 matches each other. The four anti-collision component brackets 5 are arranged in a rectangular array at the bottom of the window cleaning machine bottom plate 1. A bearing 8 is sleeved on the anti-collision component bracket 5, and a bearing sleeve 3 is sleeved on the outer edge of the bearing 8. A drop rod 10 is passed through the inner cavity of the anti-collision component bracket 5, and a drop rod return spring 9 is sleeved on the outer edge of the drop rod 10. The drop rod 10 and the drop rod return spring 9 match each other, and the bottom end of the drop rod 10 is flush with the bottom end of the bearing sleeve 3. A switch lever 4 is provided on the top of the anti-collision component bracket 5, and a light sensing module assembly 6 is provided on the side wall of the switch lever 4.

[0022] Working principle: The anti-collision and anti-fall detection mechanism of the utility model, during the collision detection process, for the use scenario of wiping doors and windows with frame, since the diameter of the bearing sleeve 3 is slightly larger than the diameter of the machine body, when the machine travels to the edge of the door and window and collides with the frame, the bearing sleeve 3 will collide with the frame before the machine body, and the bearing sleeve 3 is connected to the anti-collision component bracket 5 through the bearing 8. Under the action of the collision force, the bearing 8 drives the switch lever 4 to move, and the other end of the switch lever 4 blocks the light sensing module component 6, causing the light to change, thereby generating an electrical signal. The PCB transmits the electrical signal to the main control unit of the window cleaning machine, changes the driving trajectory, and finally realizes collision detection;

[0023] During the anti-drop detection process, for the use scenario of wiping frameless doors and windows, under the deadweight of the machine body, the drop rod 10 is compressed and shortened. When the machine travels to the edge of the door and window, the drop rod 10 exceeds the edge of the door and window before the machine body. After losing the pressure of its own weight, the drop rod 10 is slightly popped out under the elastic potential energy of the drop rod return spring 9. The drop rod 10 drives the switch lever 4 to block the light sensing module assembly 6, causing the light to change, thereby generating an electrical signal. The PCB transmits the electrical signal to the main control unit of the window cleaning machine, changes the driving trajectory, and finally realizes the anti-drop detection.

[0024] After the anti-fall detection is completed, the drop bar 10 is reset by the drop bar reset spring 9;

[0025] The anti-collision component bracket 5 and the bearing sleeve 3 are reset by the anti-collision component reset spring 7.
