[0012] Figure 2 It is a three-dimensional structural diagram of the utility model.

[0013] Figure 3 for Figure 1 Top view. DETAILED DESCRIPTION

[0014] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] As shown in the figure, the automatic leveling chassis described in the utility model includes a fixed frame 6, a movable frame 3, and a leveling hydraulic cylinder 7. The fixed frame 6 is provided with a hinge seat 5, and the lower part of the fixed frame is provided with a supporting foot 8. The rear end of the movable frame 3 is hinged to the hinge seat 5 of the fixed frame 6. The front end of the movable frame 3 is connected to the piston rod 9 of the leveling hydraulic cylinder, and the bottom of the leveling hydraulic cylinder 7 is installed on the supporting foot 8. The movable frame 3 is provided with two inclination sensors, which are respectively a first inclination sensor 1 and a second inclination sensor 2, and the first inclination sensor 1 is electrically connected to the leveling hydraulic cylinder 7.

[0016] A control module is provided on the movable frame 3, and the first inclination sensor 1, the second inclination sensor 2, and the leveling hydraulic cylinder 7 are electrically connected to the control module; the function of the control module is to receive and process the signals of the first inclination sensor 1 and the second inclination sensor 2, and output a control signal.

[0017] The sensitivity of the first inclination sensor 1 is 0.5°. When the inclination of the first inclination sensor 1 exceeds 0.5°, the first inclination sensor 1 works and transmits a signal to the control module. The control module processes the received first inclination sensor signal and outputs a control signal to the leveling hydraulic cylinder 7 to control the action of the leveling hydraulic cylinder 7 (the piston rod 9 rises or falls).

[0018] The sensitivity of the second inclination sensor 2 is 3°. When the inclination of the second inclination sensor 2 exceeds 3°, the second inclination sensor 2 works and transmits a signal to the control module. The control module processes the received second inclination sensor signal and outputs a control signal to the power controller of the window cleaning machine to cut off the power supply of the window cleaning machine and stop the window cleaning machine from working.

[0019] The hinge seat 5 is provided with a hinge shaft 4 , and the movable frame 3 is hinged to the hinge seat 5 via the hinge shaft 4 .

[0020] The working principle of the utility model is: when the window cleaning machine is working, due to the change of working state, the window cleaning machine may be tilted, thereby causing the working state of the window cleaning machine to be unbalanced. The present invention senses the tilt state through the first tilt sensor 1 and the second tilt sensor 2 arranged on the movable frame 3. When the first tilt sensor 1 detects that the movable frame is tilted more than 0.5° (low angle), the first tilt sensor 1 works and transmits the tilt signal to the control module. After the control module processes the received signal, it sends a control signal to the leveling hydraulic cylinder 7, so that the leveling hydraulic cylinder 7 starts to work, leveling the movable frame 3, so that the movable frame 3 remains in a horizontal state, so as to ensure the overall stability of the entire window cleaning machine equipment. When the movable frame 3 tilts more than 3°, the first tilt sensor 1 fails and the window cleaning machine fails. At this time, the second tilt sensor 2 works and transmits the tilt signal to the control module. After the control module processes the received signal, it sends a control signal to the window cleaning machine power controller to cut off the power supply of the window cleaning machine and stop the window cleaning machine from working.
