[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment: an automatic cleaning device for a vehicle-mounted camera mirror, comprising a camera 5, a water tank 7 fixedly connected to the top of the camera 5, two water spray pipes 6 fixedly connected to the front of the outer side of the water tank 7, a water pipe 8 fixedly connected to the middle side of the right side of the water tank 7, a water tank 25 fixedly connected to the lower front side of the camera 5, the middle side of the bottom of the water tank 25 fixedly connected to the bottom end of the water pipe 8, a filter box 14 fixedly connected to the middle of the water pipe 8, a sealing strip 13 slidably connected to the middle side of the filter box 14, and a sealing strip 13 fixedly connected to the outer side of the sealing strip 13 The filter screen 12 and the filter box 14 are provided with fixed components on both the upper and lower sides. Two blocks 11 are fixedly connected to the left side of the filter box 14. A fixed block 26 is fixedly connected between the two blocks 11. A brush 4 is slidably connected to the outside of the fixed block 26. The left side of the brush 4 is fixedly connected to the limit shell 3. A support block 24 is fixedly connected to the middle of the left side of the camera 5. A motor 2 is fixedly connected to the left side of the support block 24. A round rod 23 is fixedly connected to the output end of the motor 2. A moving block 27 is slidably connected inside the limit shell 3. A connecting rod 1 is provided between the moving block 27 and the round rod 23.

[0032] Specifically, when the system detects that there is dust on the mirror surface of the camera 5, the nozzle on the water tank 7 will immediately spray water on the mirror surface. Then, the motor 2 starts working, driving the round rod 23 to rotate, and then driving the connecting rod 1 to rotate. This rotational movement causes the movable block 27 to move left and right in the limit shell 3, thereby driving the brush 4 fixedly connected to it to slide up and down on the fixed block 26. This series of mechanical movements is to ensure that the brush 4 can comprehensively and effectively clean the dust on the mirror surface of the camera 5. When the dust on the mirror surface of the camera 5 is cleaned by the brush 4, the system will automatically stop driving the motor 2. At this time, water will flow into the water receiving trough 25 and then into the water pipe 8. The water valve 9 is opened, and the dirty water will be filtered through the filter screen 12 to remove impurities and particulate matter therein. Then, under the action of the water pump 10, the dirty water will be pumped back into the water tank 7, ready for the next cleaning work.

[0033] Reference Figure 3 and Figure 4The fixing assembly includes a mounting block 15, the outer side of the mounting block 15 is fixedly connected to the outer side of the filter box 14, a second limiting groove 16 is provided on the right side of the mounting block 15, a sliding groove 22 is provided on the left side of the mounting block 15, a plug rod 18 is slidably connected inside the second limiting groove 16, a spring 17 is fixedly connected to the plug rod 18 away from the sealing strip 13, a push rod 21 is slidably connected inside the mounting block 15, a baffle 20 is fixedly connected to the right end of the push rod 21, and a connecting rod 19 is provided between the baffle 20 and the plug rod 18

[0034] Specifically, when the filter 12 needs to be removed for cleaning, we can follow the steps below. First, push the push rod 21 to move it to the right. The push rod 21 is connected to the baffle 20, so pushing the push rod 21 will also drive the baffle 20 to move to the right. During this process, the connecting rod 19 will rotate because one end of it is connected to the baffle 20 and the other end is connected to the plug rod 18. The rotation of the connecting rod 19 will pull the plug rod 18 to move upward and compress the spring 17. The plug rod 18 was originally plugged into the inside of the sealing strip 13 to maintain the sealing state of the filter 12. When the plug rod 18 moves upward and compresses the spring 17, it will gradually detach from the sealing strip 13. When the plug rod 18 completely leaves the sealing strip 13, we can easily take out the filter 12 for cleaning. After cleaning, we need to reinstall the filter 12. At this time, loosening the push rod 21 is the key. When the push rod 21 is released, the previously compressed spring 17 releases energy and pushes the plug rod 18 to be re-inserted into the sealing strip 13. This process is automatic and does not require additional operation. The reinsertion of the plug rod 18 drives the connecting rod 2 19 to rotate, thereby driving the baffle 20 to move outward. As the baffle 20 moves, the push rod 21 is also pushed back to its original position, thereby completing the entire process of disassembling and cleaning the filter screen 12.

[0035] Reference Figure 1 - Figure 3 A water valve 9 is arranged inside the water pipe 8, a water pump 10 is installed outside the water pipe 8, the outer side of the baffle 20 is slidably connected to the inside of the slide groove 22, the plug-in rod 18 passes through the filter box 14 and is plugged into the inside of the sealing strip 13, one end of the connecting rod 1 is rotatably connected to the rear end of the moving block 27, the other end of the connecting rod 1 is rotatably connected to the front end of the round rod 23, one end of the connecting rod 2 19 is rotatably connected to the outer side of the baffle 20, the other end of the connecting rod 2 19 is rotatably connected to the left end of the plug-in rod 18, and one end of the spring 17 away from the plug-in rod 18 is fixedly connected to the inner wall of the mounting block 15.

[0036] Specifically, we see that a water valve 9 is provided inside the water pipe 8. The water valve 9 is a key component for controlling the water flow. It may be manually or automatically controlled and can be opened or closed as needed to adjust the speed or direction of the water flow. A water pump 10 is installed outside the water pipe 8. This is a key device for driving the water flow. The water pump 10 extracts liquid from the water receiving trough 25 and pushes the water tank 7 through its internal mechanical device to circulate the liquid in the system. In addition, we notice that the outer side of the baffle 20 is slidably connected to the inside of the chute 22. This design allows the baffle 20 to slide freely on the track of the chute 22. The filter box 14 may be used to filter impurities in the water. The sealing strip 13 ensures that the connection between the plug rod 18 and the filter box 14 is tight to prevent water leakage. Similarly, one end of the connecting rod 19 is rotatably connected to the outside of the baffle 20, and the other end is rotatably connected to the left end of the plug rod 18. This design forms a linkage mechanism between the baffle 20 and the plug rod 18. When the baffle 20 slides, the plug rod 18 will also move accordingly, thereby realizing disassembly and installation. The spring 17 plays a resetting role here. When the plug rod 18 or the baffle 20 is subjected to external force, the spring 17 can provide a certain elastic resistance or restoring force to ensure the stability and reliability of the system.

[0037] Working principle: when there is dust on the mirror surface of the camera 5, the water spray pipe 6 on the water tank 7 sprays water on the mirror surface of the camera 5, starts the motor 2, drives the round rod 23 to rotate, and then drives the connecting rod 1 to rotate, thereby driving the moving block 27 to move left and right in the limit shell 3, and then drives the brush 4 connected to it to slide up and down on the fixed block 26. When the dust on the mirror surface of the camera 5 is cleaned by the brush 4, the driving motor 2 is stopped at this time, and the water will flow into the water receiving trough 25, and then into the water pipe 8. The water valve 9 is opened, and the dirty water will be filtered through the filter screen 12 and then discharged again under the action of the water pump 10. So that it enters the water tank 7. When the filter 12 needs to be removed for cleaning, the push rod 21 is pushed, driving the baffle 20 to move to the right, thereby driving the connecting rod 19 to rotate, thereby pulling the plug rod 18 to move upward, thereby compressing the spring 17, until the plug rod 18 completely leaves the sealing strip 13, at this time the filter 12 can be taken out. After cleaning, release the push rod 21, and the compressed spring 17 will push the plug rod 18 to be re-inserted into the inside of the sealing strip 13, thereby driving the connecting rod 19 to rotate, thereby driving the baffle 20 to move outward, and then pushing the push rod 21.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
