Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted camera technology, and in particular to a dirt removal camera device. Background Technology

[0002] With the development of automotive electronics technology, various in-vehicle camera devices have emerged to meet needs such as providing drivers with a more comprehensive view, recording in-vehicle images, and enhancing driving safety. However, during vehicle use, these cameras easily accumulate dust, water droplets, mud, and other dirt, affecting the clarity of the image and requiring manual cleaning. However, when the vehicle is in motion, this dirt cannot be wiped away promptly, especially in rainy or snowy weather, where rainwater easily adheres to the camera lens, resulting in unclear images and affecting the driver's visibility, thus creating driving risks.

[0003] The existing technology (authorization announcement number CN217037260U) provides a rearview camera with a flow-guiding structure. A first flow-guiding structure is located on the bottom shell of the rearview camera, and a second flow-guiding structure is located above the lens. During vehicle movement, air is introduced through the first flow-guiding structure and then discharged through the second flow-guiding structure. The discharged air blows away rain or snow from the lens below the second flow-guiding structure. However, the existing technology lacks an internal flow-guiding structure. After air enters the camera housing from the first flow-guiding structure, turbulence forms inside the housing due to its large and numerous gaps. This prevents the air from quickly discharging from the second flow-guiding structure, and the turbulence reduces the airflow speed, making it difficult to remove rain or snow from the lens. The removal effect is even worse if dust or mud adheres to the lens. Furthermore, there is no drainage structure; during driving, not only air but also rain or snow enters the camera housing through the first flow-guiding structure. When rainwater or snowflakes enter the camera housing, they can accumulate inside the housing and even adhere to the internal electronic components, posing a risk of short circuits. Utility Model Content

[0004] In order to solve the problems in the prior art, this utility model provides a dirt removal camera device.

[0005] This utility model provides a dirt removal camera device, including a housing 1 and a camera 2. The housing 1 is provided with an air inlet 11, a lens hole 12, and an air outlet 13. The camera 2 is disposed inside the housing 1, and the lens of the camera 2 is adapted to the lens hole 12. The air inlet 11 is located on the windward side of the housing 1, and the air outlet 13 is located on the side away from the air inlet 11 and close to the lens hole 12. A ventilation channel for airflow guidance is provided inside the housing 1, and the ventilation channel is located between the air inlet 11 and the air outlet 13. During vehicle operation, air enters through the air inlet 11 and exits through the air outlet along the ventilation channel. The exiting air blows onto the lens. Due to the guiding effect of the ventilation channel, the air entering the housing 1 does not form turbulence, thus achieving a powerful high-speed airflow that more easily blows away dirt on the lens.

[0006] As a further improvement of this utility model, the ventilation channel is composed of a housing 1 and a ventilation baffle 15 disposed within the housing. Preferably, the ventilation baffle 15 is a strip-shaped baffle disposed between the air inlet 11 and the air outlet 13. The ventilation baffle 15 and the housing together form a ventilation channel for airflow guidance. The specific shape of the ventilation baffle 15 can also be a long arc shape or a tubular shape, or other shapes.

[0007] As a further improvement of this utility model, a drain hole 14 is provided at one end of the housing near the vehicle body. Since water vapor can enter the housing space outside the ventilation channel and accumulate inside the housing when the housing and ventilation baffle of the cleaning camera device are not completely closed during use, a drain hole is provided at the lower end of the housing. The number and shape of the drain hole are not limited so that the water accumulated inside the housing can be discharged by gravity.

[0008] As a further improvement of this utility model, a diversion device is also provided inside the housing 1 for diverting the air entering the housing 1. Based on gravity-driven drainage, the diversion device is installed between the air inlet and the ventilation channel to divert the air entering the housing, so that part of the air enters the ventilation channel and part enters the housing outside the ventilation channel. As a further improvement of this utility model, the diversion device includes a first diversion plate 16, which is disposed between the air inlet 11 and the ventilation channel. This allows the air entering the ventilation channel to be discharged through the exhaust port to clean the lens, while the air entering the housing outside the ventilation channel drains the water inside the housing through the drain port.

[0009] As a further improvement of this utility model, the air diversion device further includes a second air diversion plate 17, which is disposed between the first air diversion plate 16 and the ventilation channel, and the first air diversion plate 16 and the second air diversion plate 17 are staggered. When there is heavy rain, more rainwater enters through the air inlet, resulting in the air discharged from the exhaust port carrying more moisture. While blowing away the rainwater on the lens, it also brings in some moisture, leaving some moisture on the lens and causing the image to be blurry. Therefore, a second air diversion plate is further disposed between the first air diversion plate and the ventilation channel, and the first air diversion plate and the second air diversion plate are staggered. The air diverted by the first air diversion plate is diverted a second time before entering the ventilation channel, so that as much moisture in the air as possible is diverted into the housing outside the ventilation channel and discharged through the drain hole. This results in less moisture content in the air entering the ventilation channel, and the airflow is relatively gentler. This ensures that the air discharged from the exhaust port can effectively clean the lens without causing secondary dirt to the lens due to excessive moisture content, thus ensuring a clear image.

[0010] As a further improvement of this utility model, a first baffle plate 18 is provided inside the housing 1 on the side near the air outlet 13 and away from the air inlet 11. The first baffle plate near the air outlet 13 prevents turbulence within the housing, allowing water to be discharged more smoothly from the drain hole, thus more effectively draining water from the housing outside the ventilation channel. As a further improvement of this utility model, a second drain baffle plate 19 is provided inside the housing 1 on the side near the drain hole 14. This further allows moisture from the housing outside the ventilation channel to be discharged through the drain hole.

[0011] As a further improvement of this utility model, the ventilation baffle is provided with a water-draining hole 150. The moisture in the ventilation channel enters the housing outside the ventilation channel through the water-draining hole and is discharged from the drain hole, which further reduces the moisture in the ventilation channel and prevents the accumulation of residual moisture in the ventilation channel, so that the air outlet has less water content, effectively cleans the lens and avoids secondary dirt on the lens.

[0012] As a further improvement of this utility model, it also includes a bottom cover 3 disposed on the bottom surface of the housing 1, through which the dirt removal camera device is disposed on the vehicle body, and the bottom cover 3 can be fixed to the vehicle body by adhesive.

[0013] The beneficial effects of this invention are as follows: By setting a ventilation channel inside the camera device housing, the air entering the housing from the air inlet is guided, thereby allowing the air exiting from the air outlet to be blown onto the lens. This avoids turbulence within the housing, and during operation, the powerful, high-speed airflow based on natural airflow more easily removes dirt from the lens. Simultaneously, a diversion device is installed inside the housing to ensure that even in rainy or snowy weather, excess rainwater entering from the air inlet is diverted by the diversion device, allowing the high-speed airflow, containing some rainwater, to exit from the air outlet and clean the lens, blowing away water vapor or washing away dust, dirt, and other contaminants, resulting in a cleaner and clearer lens.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model provides a dirt removal camera device, such as Figure 1-3 As shown, the device includes a housing 1 and a camera 2. The housing 1 is provided with an air inlet 11, a lens hole 12, and an air outlet 13. The camera 2 is disposed inside the housing 1, and the lens of the camera 2 is adapted to the lens hole 12. The air inlet 11 is located on the windward side of the housing 1, and the air outlet 13 is located on the side away from the air inlet 11 and close to the lens hole 12. Preferably, the air outlet 13 and the lens hole 12 are located on the same side, and the air discharged from the air outlet 13 can blow onto the lens of the lens hole 12. A ventilation channel for airflow guidance is provided inside the housing 1, and the ventilation channel is located between the air inlet 11 and the air outlet 13. During vehicle operation, air enters through the air inlet 11, and the air is discharged from the air outlet along the ventilation channel. The discharged air blows onto the lens. Because of the guiding effect of the ventilation channel, the air entering the housing 1 will not form turbulence, thereby achieving a strong high-speed airflow that more easily blows away dirt on the lens.

[0025] In this embodiment, further, such as Figure 3As shown, the ventilation channel consists of a housing 1 and a ventilation baffle 15 disposed within the housing. Preferably, the ventilation baffle 15 is a strip-shaped baffle disposed between the air inlet 11 and the air outlet 13. The ventilation baffle 15 and the housing together form a ventilation channel for airflow. The specific shape of the ventilation baffle 15 can also be a long arc shape or a tubular shape, or other shapes.

[0026] Based on the above embodiments, a drainage hole 14 is further provided at one end of the housing near the vehicle body. Since water vapor can enter the housing space outside the ventilation channel and accumulate inside the housing when the housing of the cleaning camera device and the ventilation baffle are not completely closed during use, a drainage hole is provided at the lower end of the housing. The number and shape of the drainage holes are not limited so that the water accumulated inside the housing can be discharged by gravity.

[0027] In this embodiment, the housing 1 is further provided with a diversion device for diverting the air entering the housing 1. Based on gravity drainage, the diversion device, located between the air inlet and the ventilation channel, diverts the air entering the housing, allowing some air to enter the ventilation channel and some to enter the housing outside the ventilation channel. Preferably, the diversion device includes a first diversion plate 16, which is preferably strip-shaped or has other diversion structures such as textured, uneven, or perforated partitions. The first diversion plate 16 is disposed between the air inlet 11 and the ventilation channel, allowing air entering the ventilation channel to be discharged through the exhaust port to clean the lens, and air entering the housing outside the ventilation channel to drain water from the housing through the drain port.

[0028] Based on the above embodiments, the diversion device further includes a second diversion plate 17, which is disposed between the first diversion plate 16 and the ventilation channel. The first diversion plate 16 and the second diversion plate 17 are staggered. The first diversion plate 16 and the second diversion plate 17 are preferably strip-shaped plates, or other structures with diversion functions such as textured, uneven, or hollow partitions. When there is heavy rain, more rainwater enters through the air inlet, causing the air discharged from the exhaust port to carry more moisture. While blowing away the rainwater on the lens, it also brings in some moisture, leaving some moisture on the lens and causing the image to be blurry. Therefore, a second diverter is further installed between the first diverter and the ventilation channel, and the first and second diverters are staggered. The air diverted by the first diverter is diverted a second time before entering the ventilation channel, so that as much moisture in the air as possible is diverted into the housing outside the ventilation channel and discharged through the drain hole. This results in less moisture in the air entering the ventilation channel and a gentler airflow. As a result, the air discharged from the exhaust hole can effectively clean the lens without causing secondary dirt to the lens due to high moisture content, thus ensuring a clear image.

[0029] In this embodiment, a first baffle plate 18 is further provided inside the housing 1 on the side near the vent 13 and away from the vent 11. The baffle plate prevents turbulence within the housing, allowing water to drain more smoothly from the drain hole, thus more effectively removing water that has entered the housing outside the ventilation channel. As a further improvement, a second drain baffle plate 19 is provided inside the housing 1 on the side near the drain hole 14. This further allows moisture from the housing outside the ventilation channel to drain through the drain hole.

[0030] In this embodiment, the ventilation baffle is further provided with drainage holes 150. Moisture in the ventilation channel enters the housing outside the ventilation channel through the drainage holes and is discharged through the drain holes, further reducing the moisture in the ventilation channel and preventing residual moisture from accumulating in the ventilation channel. This results in less water content in the air outlet, effectively cleaning the lens and preventing secondary contamination of the lens. Furthermore, as... Figure 4-5 As shown, the housing 1 is provided with a cable outlet hole 10. Specifically, the first baffle plate is provided with a cable hole so that the camera cable passes through the cable hole and the cable outlet hole 10. In other embodiments, a wireless camera or a cable outlet from the bottom cover or vehicle body can also be used. Furthermore, a bottom cover 3 is provided on the bottom surface of the housing 1, through which the cleaning camera device is mounted on the vehicle body. The bottom cover 3 can be fixed to the vehicle body by adhesive.

[0031] Advantages of this technical solution: The cleaning camera device provided in this embodiment, by setting a ventilation channel inside the camera device housing, guides the air entering the housing from the air inlet, thereby ensuring that the air exhausted from the air outlet blows onto the lens, avoiding air turbulence within the housing. When the car is in motion, the powerful, high-speed airflow based on natural airflow more easily blows away dirt from the lens. Simultaneously, a diversion device is installed inside the device housing, so that even in rainy or snowy weather, when air carrying rainwater enters from the air inlet, the diversion device discharges excess rainwater, allowing the high-speed airflow carrying some rainwater to exit from the air outlet and clean the lens, blowing away water mist or washing away dust, mud, and other dirt, resulting in a cleaner and clearer lens.

[0032] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
