[0018] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. Without conflict, the technical features in the embodiments of this application and the embodiments can be combined with each other.

[0019] As Figure 1 , Figure 2 shown, a camera cleaning device for a new energy commercial vehicle includes an electric air compressor 1, an air storage tank 3, a camera 7 installed on the vehicle, a display screen 8 located in the middle of the instrument panel, and a vehicle controller 10. The electric air compressor 1 is respectively connected to the air storage tank 3 and the vehicle controller 10. The vehicle controller 10 controls the electric air compressor 1 to inflate the air storage tank 3. The camera 7 is connected to the display screen 8, and the display screen 8 displays the picture formed by the image stitching of the camera 7.

[0020] It further includes a high-pressure gas pipeline connected to the air storage tank 3, a jet nozzle 6 installed near the camera 7, and a rocker switch 9. A multi-way distribution valve 4 is installed on the high-pressure gas pipeline. The multi-way distribution valve 4 distributes the high-pressure gas pipeline into multiple gas pipelines 2. The gas pipelines 2 are connected to the jet nozzle 6. Solenoid valves 5 are installed on each gas pipeline 2. The rocker switch 9 is connected to the solenoid valves 5, and the rocker switch 9 is used to control the opening or closing of the solenoid valves 5.

[0021] In some embodiments, as Figure 1 shown, a pressure sensor 11 for real-time monitoring of the air pressure value in the air storage tank 3 is installed on the air storage tank 3. The pressure sensor 11 is connected to the vehicle controller 10. The high-pressure gas in the air storage tank 3 is maintained at 0.7 Mpa - 1 Mpa. The vehicle controller 10 monitors the air pressure value in the air storage tank 3 in real time through the pressure sensor 11. When the air pressure value is less than 0.7 Mpa, the vehicle controller 10 gives a control signal to the electric air compressor 1 to turn on the electric air compressor 1 to inflate the air storage tank 3. When the air pressure reaches the upper limit threshold of 1.0 Mpa, the vehicle controller 10 gives a control signal to the electric air compressor 1 to turn off the electric air compressor 1 and stop inflating the air storage tank 3.

[0022] In some embodiments, as Figure 1 , Figure 2As shown, there are four cameras 7, which are evenly distributed around the vehicle, and the display screen 8 forms a 360° surround view by stitching the images of the four cameras 7. The display screen 8 in the middle of the instrument panel stitches the images of the four external surround cameras corresponding to the cameras 1, 2, 3, and 4 around the vehicle to form a 360° surround view. The driver can observe the environmental information around the vehicle through the display screen 8. When the surface of a camera 7 is covered with dust and dirt, the corresponding picture on the display screen 8 will have black spots or areas, which will affect the driver's understanding of the environmental information on the corresponding side, thereby affecting the driver's driving safety. The driver can determine through the display screen 8 that a camera has dirt and needs to be cleaned.

[0023] In some embodiments, Figure 1 As shown, the air nozzle 6 is conical, which is convenient for increasing the blowing pressure on the surface of the camera 7 and achieving a better blowing and sewage removal effect.

[0024] In some embodiments, the rocker switch 9 is a self-resetting switch. Multiple rocker switches 9 correspond to multiple cameras one by one. Assuming that there is stain on the surface of camera No. 1, the driver can press the corresponding rocker switch 9. When the rocker switch is closed, the solenoid valve 5 corresponding to camera No. 1 is powered on and opened, and the gas inside the gas cylinder 3 passes through the corresponding gas pipeline 2 and the solenoid valve 5 to the air nozzle 6 corresponding to camera No. 1. The high-pressure gas blows air to the surface of camera No. 1 through the air nozzle 6 to remove dirt.

[0025] In the same principle, when the second camera needs to be cleaned, the driver can press the rocker switch 9 corresponding to the second camera, and the solenoid valve 5 is powered on and opened, and the high-pressure gas blows the surface of the second camera through the air nozzle 6 of the second camera to remove dirt. The camera can be cleaned with one click, and the operation is very convenient.

[0026] A second aspect of the utility model provides a vehicle, on which the new energy commercial vehicle camera cleaning device is installed, and the vehicle is preferably a new energy commercial vehicle.
