[0035] The embodiment of the utility model provides a cleaning device, including a cleaning component 100, a main rotating shaft 200, a driving component 300 and a transmission component 400. The cleaning component 100 is installed on the outer side of a panel 500, and the cleaning component 100 can clean the surface of the panel 500; the main rotating shaft 200 is penetrated through the panel 500, and the cleaning component 100 is connected to the main rotating shaft 200, and the main rotating shaft 200 can drive the cleaning component 100 to swing back and forth relative to the panel 500; the driving component 300 includes a rotating motor 310, and the driving component 300 is installed on the inner side of the panel 500; the transmission component 400 is installed on the inner side of the panel 500, and the transmission component 400 is connected to the rotating shaft of the rotating motor 310 and the main rotating shaft 200, and the transmission component 400 can convert the rotational motion of the rotating shaft of the rotating motor 310 into a reciprocating swinging motion of the cleaning component 100 with the main rotating shaft 200 as the axis.

[0036] According to the cleaning device of the embodiment of the utility model, Figures 1 to 5 As shown, the driving assembly 300 includes a rotating motor 310 and a gear box 320. The driving assembly 300 provides rotational power for the cleaning device. The driving assembly 300 drives the main rotating shaft 200 to rotate through the transmission assembly 400. The main rotating shaft 200 drives the cleaning assembly 100 to rotate. The cleaning assembly 100 scrapes the lens 600 on the panel 500 back and forth to clean. The rotating shaft of the driving assembly 300 always rotates in the same direction. Every time the rotating shaft of the driving assembly 300 rotates one circle, the transmission assembly 400 must experience a process of driving the main rotating shaft 200 to rotate forward and then reverse. The main rotating shaft 200 drives the cleaning assembly 100 to rotate from the starting position to the ending position, and then rotates from the ending position to the starting position to complete one cleaning of the lens 600. Therefore, the left and right swing of the cleaning assembly 100 can be achieved without installing the sensor 700. The working process of the entire cleaning device is completed by the cooperation of the mechanical components to avoid the failure of the cleaning process caused by the failure of the sensor 700, which is safe and reliable.

[0037] In some embodiments, Figure 2 As shown, the transmission assembly 400 includes a driving rod 410, a connecting rod 420 and a swing arm 430.

The other end of the connecting rod 420 is rotatably connected to one end of the swing arm 430. The other end of the swing arm 430 is fixedly connected to the main rotating shaft 200. The rotation of the rotating shaft of the rotating motor 310 drives the driving rod 410 to rotate. The driving rod 410 drives the connecting rod 420 to move. The connecting rod 420 drives the main rotating shaft 200 to rotate forward or reverse. The transmission assembly 400 converts the forward rotation of the rotating shaft of the rotating motor 310 into the forward rotation or reverse rotation of the main rotating shaft 200 through the driving rod 410, the connecting rod 420 and the swing arm 430.

[0038] In some other embodiments, the transmission assembly 400 may adopt other connection methods as long as it can achieve the conversion of the forward rotation of the shaft of the rotating motor 310 into the forward or reverse rotation of the main shaft 200 .

When the rotating shaft of the rotating motor 310 drives the first connecting portion 411 to rotate, the second connecting portion 412 performs a circular motion relative to the first connecting portion 411.

[0040] In some embodiments, Figure 3 As shown, the cleaning device further includes a sensor 700, which is connected to the rotating motor 310 by signal. The driving rod 410 further includes a detection part 413, which is located at one side of the first connecting part 411. The detection part 413 triggers the sensor 700 once each time the driving rod 410 rotates one circle. The cleaning assembly 100 completes one cleaning operation each time the driving rod 410 rotates one circle. Each time the detection part 413 triggers the sensor 700, the cleaning assembly 100 is located at the starting position. When the cleaning device completes cleaning, the control unit of the cleaning device detects the signal of the sensor 700, and the control unit controls the driving assembly 300 to stop running, thereby ensuring that the cleaning assembly 100 can stop at the starting position to avoid blocking the lens 600.

[0041] In some embodiments, Figure 3 As shown, the cleaning device further comprises a bracket 800, which is fixedly connected to the inner side of the panel 500, and the rotating motor 310 and the sensor 700 are fixedly mounted on the bracket 800.

[0043] In some embodiments, Figure 4As shown, the fixing seat 900 can limit the rotation angle of the swing arm 430. The fixing seat 900 is provided with a limiting portion, which is a curved plate protruding from the fixing seat 900, which can prevent the swing arm 430 from swinging too much in an accidental situation, causing the cleaning assembly 100 to swing beyond the working range.
