Description

Technical Field

[0001] This utility model belongs to the field of vehicle camera technology, specifically relating to an automatic dust removal mechanism for vehicle camera lenses. Background Technology

[0002] With the rapid development of intelligent transportation and autonomous driving technologies, vehicle cameras, as important sensors for vehicles to perceive the external environment, have their performance and reliability directly related to driving safety and driving experience. In recent years, with the continuous advancement of automotive electronics technology, vehicle cameras have made significant improvements in resolution, field of view, and night vision capabilities. However, the problem of cleaning camera lenses has always plagued technicians in the industry.

[0003] Vehicle cameras are typically installed on the exterior of vehicles and are constantly exposed to complex and changing driving environments, such as dust, mud, and insect residue on city roads, and oil stains and flying stones on highways. These contaminants easily adhere to the camera lens surface, causing blurred images and color distortion. In severe cases, they may even completely obstruct the lens's field of view, affecting the normal functioning of functions such as driving monitoring, road recognition, and obstacle detection. To address this issue, most existing vehicle cameras use manual cleaning or fixed dust removal devices. While manual cleaning can directly remove contaminants from the lens surface, it is cumbersome and requires the vehicle to be stationary, making it impossible to guarantee the cleanliness of the camera in real time. Fixed dust removal devices, such as air blowers or windshield wipers, can reduce lens contamination to some extent, but they are often complex in structure, take up a lot of space, and have limited dust removal effect, especially for cleaning fine particles and stubborn stains. Therefore, improvements are needed. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) Through the setup of the camera body, assembly plate, rotating plate and cleaning brush, when in use, the servo motor drives the assembly plate to rotate horizontally through the drive rod to switch between working position and storage position: when dust removal is not required, the assembly plate can be rotated to the bottom of the camera body to hide and avoid obstructing the lens view; when starting, the assembly plate rotates to the front of the lens, and the drive motor in the motor box fixed on its surface drives the rotating plate to rotate vertically through the transmission rod, driving multiple sets of cleaning brushes to clean the protective lens surface in a circumferential manner, effectively removing the attached dust.

[0024] Example 1:

[0025] Please see Figures 1 to 4 As shown, an automatic dust removal mechanism for vehicle-mounted camera lenses includes: a camera body 1;

[0026] A fixing clip 2 is fixedly connected to the bottom of the camera body 1. The camera body 1 serves as the core carrier, and the fixing clip 2 securely installs it in the designated position on the vehicle. A protective box 3 is fixedly connected to one side of the fixing clip 2. The protective box 3 is used to protect the internal servo motor 4. The servo motor 4 is fixedly connected to the inner wall of the protective box 3. A drive rod 5 is installed at the output end of the servo motor 4. An assembly plate 6 is fixedly connected to one end of the drive rod 5. The servo motor 4 drives the assembly plate 6 to rotate horizontally through the drive rod 5, realizing the switching between the working position and the storage position.

[0027] A motor box 7 is fixedly connected to the surface of the assembly plate 6. A drive motor 8 is fixedly connected to the inner wall of the motor box 7. A transmission rod 9 is installed at the output end of the drive motor 8. A rotating disk 10 is fixedly connected to the top of the transmission rod 9. The surface of the rotating disk 10 is rotatably connected to the inner wall of the assembly plate 6. Multiple sets of cleaning brushes 11 are fixedly connected to the top of the rotating disk 10. When dust removal is not required, the assembly plate 6 can be rotated to the bottom of the camera body 1 to avoid obstructing the lens view. When started, the assembly plate 6 rotates to the front of the lens. The drive motor 8 in the motor box 7 fixed to its surface drives the rotating disk 10 to rotate vertically through the transmission rod 9, driving multiple sets of cleaning brushes 11 to perform circumferential cleaning of the protective lens surface 12, effectively removing the attached dust. The protective lens surface 12 is fixedly connected to the surface of the camera body 1, and the surface of the cleaning brushes 11 overlaps the surface of the protective lens surface 12. The protective lens surface 12 serves as a lens protection layer and is in close contact with the brushes to ensure thorough cleaning.

[0028] Example 2:

[0029] Please see Figures 1 to 4 As shown, a mounting box 13 is fixedly connected to the surface of the camera body 1. An air pump 14 is fixedly connected to the inner wall of the mounting box 13. The mounting box 13 is fixed to the surface of the camera body 1, providing a stable mounting space for the air pump 14. An air outlet pipe 15 is installed at the output end of the air pump 14. An arc-shaped connecting pipe 16 is fixedly connected to the bottom end of the air outlet pipe 15, and the inner side of the arc-shaped connecting pipe 16 overlaps the surface of the protective lens 12. Multiple sets of exhaust pipes 17 are fixedly connected to the inner wall of the arc-shaped connecting pipe 16. The camera body 1 is arranged in an arc shape, with a wire 18 fixedly connected to the back. After the air pump 14 is powered by the wire 18 and started, compressed air is delivered to the arc-shaped connecting pipe 16 through the air outlet pipe 15. This pipe is arranged close to the edge of the protective mirror 12, and multiple sets of arc-shaped exhaust pipes 17 are evenly distributed on its inner side, so that the high-pressure airflow is sprayed onto the mirror at a fan angle. Combined with the mechanical cleaning of the cleaning brush 11, residual dust and fine particles are further blown away to ensure that the mirror is thoroughly cleaned. The wire 18 provides power support for the entire system.

[0030] Example 3:

[0031] Please see Figures 1 to 4 As shown, in urban public transportation systems, buses and taxis widely use onboard cameras for driving recording, monitoring passenger behavior, and assisting driving. However, these vehicles are easily affected by pollutants such as dust, raindrops, and mud during operation, which can obstruct the camera lens, affect the image clarity, and thus reduce the monitoring effect and driving safety. The lens contamination problem is more prominent, especially in inclement weather or dusty environments. Therefore, there is a need for a device that can automatically clean the lens and ensure image quality.

[0032] An automatic dust removal mechanism for vehicle-mounted camera lenses is installed on the camera modules of buses or taxis. The camera body is securely fixed to a designated position on the vehicle using clamps, ensuring the protective lens faces outwards for clear imaging of the road and surrounding environment.

[0033] When the camera detects that the image is blurred due to dust or dirt on the lens surface (this can be triggered by image analysis or a timer), the system automatically starts the dust removal program. The servo motor drives the assembly tray to rotate from the bottom of the camera to the front of the lens via a drive rod, ready for cleaning.

[0034] Once the assembly tray is in place, the drive motor inside the motor box starts, driving the rotating disk to rotate vertically via a transmission rod. This, in turn, causes multiple sets of cleaning brushes to perform a circumferential cleaning of the protective mirror surface. The rotational motion of the brushes effectively removes dust and dirt adhering to the mirror surface.

[0035] Simultaneously, the air pump is started by power supply via a wire, and compressed air is delivered to the arc-shaped connecting pipe through the exhaust pipe. The arc-shaped connecting pipe is arranged close to the edge of the protective mirror, and multiple sets of exhaust pipes on its inner side spray high-pressure airflow at a fan angle to further blow away residual dust and fine particles, ensuring that the mirror surface is thoroughly cleaned.

[0036] After cleaning, the servo motor rotates in the opposite direction, driving the mounting plate back to the bottom of the camera to hide it and avoid obstructing the lens's field of view. The camera then returns to a clear shooting state, continuing to provide high-quality images for dashcams or surveillance.

[0037] The system can repeat the cleaning process as needed or according to environmental conditions to ensure that the lens is always clean and adapts to the complex and ever-changing urban driving environment.

[0038] Working Principle: The camera body, as the core carrier, is installed in a designated position on the vehicle via a fixing clamp. A protective box protects the internal servo motor. The servo motor drives a drive rod to rotate the mounting plate horizontally, switching between the working and storage positions. When dust removal is not required, the mounting plate rotates to the bottom of the camera body to avoid obstructing the lens's view. When dust removal is activated, the mounting plate rotates to the front of the lens, and the drive motor inside the motor box on its surface drives a rotating disk to rotate vertically via a transmission rod. This drives multiple sets of cleaning brushes to perform a circumferential cleaning of the protective lens surface. The protective lens surface, acting as a lens protection layer, adheres tightly to the brushes to ensure thorough cleaning. Efficient dust removal is achieved through the coordinated control of two motors. Simultaneously, the air pump inside the installation box is powered by a wire and starts. Compressed air is delivered to the arc-shaped connecting pipe through the air outlet pipe. The arc-shaped connecting pipe is arranged close to the edge of the protective mirror. Multiple sets of arc-shaped exhaust pipes on its inner side spray high-pressure airflow at a fan angle. The high-pressure airflow, together with the mechanical cleaning of the cleaning brush, further blows away residual dust and fine particles. The wire provides power support for the entire system to achieve efficient collaborative operation of automated dust removal and air blowing assistance. After cleaning, the assembly tray rotates to retract into the storage position to ensure seamless switching between dust removal and shooting modes for the camera. The entire system achieves efficient dust removal while also ensuring concealed storage through the combination of dual motor drive and air blowing assistance.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
