[0001] This utility model relates to the field of camera technology, and in particular to a waterproof blind spot camera for vehicles. Background Technology

[0002] With the rapid development of the automotive industry and the increasing emphasis on driving safety, the demand for safety assurance during vehicle operation is growing daily. In everyday driving scenarios, due to the limitations of the vehicle's structure, there are many areas where the driver's view is obstructed and cannot be directly observed when in the normal driving seat—these are blind spots. These blind spots can easily become potential risk points for traffic accidents when the vehicle is turning, changing lanes, or reversing, thus requiring cameras for monitoring and recording.

[0003] Currently, one type of waterproof blind spot camera for vehicles is prone to getting rainwater on its lens in rainy weather, resulting in blurred images and changes in focus. Even with the use of hydrophobic or hydrophilic films, it is difficult to completely solve the problem and cannot meet the requirements of automotive safety products. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the prior art, lenses are easily covered with rainwater on rainy days, resulting in blurred images and changes in focal length. Even with the use of hydrophobic or hydrophilic films, it is difficult to completely solve the problem and meet the requirements of automotive safety products. Therefore, this invention proposes a waterproof blind spot camera for vehicles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle-mounted waterproof blind spot camera, comprising a protective housing, a camera body placed inside the protective housing, a top cover installed on the top of the protective housing by bolts, a sealing structure for sealing the gap between the top cover and the protective housing, a small hole matching the lens of the camera body being opened at the front end of the protective housing, an air inlet being opened at the rear end of the protective housing, and two connecting grooves being opened inside the protective housing, one end of the two connecting grooves communicating with the small hole, and the other end of the two connecting grooves communicating with the air inlet.

[0006] Preferably, the sealing structure includes a first sealing ring fixed to the bottom of the top cover, and the top of the protective shell has a sealing groove that matches the first sealing ring.

[0007] Preferably, a base plate is provided below the protective shell, and a fixing frame is fixed on both sides of the top of the base plate. The protective shell is located between the two fixing frames and is rotatably connected to the two fixing frames. A motor is installed in one of the fixing frames, and the output end of the motor is fixed to the protective shell.

[0008] Preferably, the base plate has a communicating cavity, and the base plate has mounting grooves on both sides of the communicating cavity. A second sealing ring is installed in the fixing frame on the outside of the motor.

[0009] Preferably, a first drainage groove is provided on the inner wall of the small hole inside the protective shell, and a second drainage groove is provided at the front end of the protective shell, the second drainage groove being connected to the first drainage groove.

[0010] Preferably, the inner wall of the protective shell is provided with heat dissipation grooves at both ends, and the opposite ends of the two heat dissipation grooves are respectively connected to two connecting grooves. A first baffle is fixed above the small hole at the front end of the protective shell, and a second baffle matching the air inlet hole is fixed at the rear end of the protective shell.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the camera body is encased in a protective shell and top cover to prevent direct contact with rainwater. A small hole, matched to the camera lens, allows the lens to capture images of the external environment through the hole, utilizing the pinhole imaging principle. This device is installed at the rear of a vehicle for rearward monitoring. During movement, air enters through the air inlet, flows through the connecting channel, and finally exits through the small hole, the first drainage channel, and the second drainage channel. Even if some water droplets enter the small hole, the airflow disperses the rainwater around and in front of the hole, preventing further water ingress and achieving bidirectional waterproofing. This solves the problem of water getting on the lens. Furthermore, when the vehicle is stationary, the first and second drainage channels guide and drain the rainwater from the small hole, further enhancing the waterproofing performance.

[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a waterproof blind spot camera for vehicles, including a protective shell 1, a camera body 2 placed inside the protective shell 1, a top cover 11 installed on the top of the protective shell 1 by bolts 12, a sealing structure 13 for sealing the gap between the top cover 11 and the protective shell 1, a small hole 3 matching the lens of the camera body 2 opened at the front end of the protective shell 1, an air inlet 4 opened at the rear end of the protective shell 1, and two connecting grooves 5 opened inside the protective shell 1, one end of the two connecting grooves 5 communicating with the small hole 3, and the other end of the two connecting grooves 5 communicating with the air inlet 4.

[0021] The overall effect of Embodiment 1 is that the camera body 2 is wrapped by the protective shell 1 and the top cover 11 to prevent it from directly contacting rainwater. The small hole 3 is matched with the lens of the camera body 2. Utilizing the imaging principle of the small hole 3, the lens can still capture external scenes through the small hole 3. This device is installed at the rear of the vehicle to monitor the rear direction of the vehicle. When moving, the wind enters through the air inlet 4, flows through the connecting groove 5, and finally exits through the small hole 3, the first drainage groove 7, and the second drainage groove 8. Even if some water droplets enter the small hole 3, the airflow will blow away the rainwater around and in front of the small hole 3, preventing rainwater from entering through the small hole 3, achieving two-way waterproofing and solving the problem of water getting on the lens. The sealing structure 13 can seal the gap between the top cover 11 and the protective shell 1 to prevent rainwater from entering.

[0022] Example 2, as Figure 1-4As shown, the sealing structure 13 includes a first sealing ring 1301 fixed to the bottom of the top cover 11. A sealing groove 1302 matching the first sealing ring 1301 is provided at the top of the protective shell 1. A bottom plate 14 is provided below the protective shell 1. Fixing brackets 15 are fixed to both sides of the top of the bottom plate 14. The protective shell 1 is positioned between the two fixing brackets 15 and rotatably connected to them. A motor 16 is installed inside one of the fixing brackets 15. The output end of the motor 16 is fixed to the protective shell 1. A communicating cavity 18 is provided inside the bottom plate 14. The bottom plate 14 is located within the communicating cavity 18. Mounting slots 19 are provided on both sides.

A first baffle 9 is fixed above the small hole 3 at the front end of the protective shell 1. A second baffle 10 matching the air inlet 4 is fixed at the rear end of the protective shell 1.

[0023] The overall effect of Embodiment 2 is that when the vehicle body is not moving, the first drainage groove 7 and the second drainage groove 8 will also guide and discharge the rainwater in the small hole 3, resulting in stronger waterproof performance. When the top cover 11 and the protective shell 1 are installed, the first sealing ring 1301 will be inserted into the sealing groove 1302 to seal the gap between the top cover 11 and the protective shell 1, preventing rainwater from entering. The operation of the motor 16 can drive the protective shell 1 to rotate as a whole, thereby adjusting its monitoring angle. The setting of the connecting cavity 18 and the setting of the wiring hole at the bottom of the protective shell 1 facilitates the wiring of the camera body 2 inside the protective shell 1. The setting of the mounting groove 19 facilitates the installation of the base plate 14. The setting of the second sealing ring 17 can seal the gap between the fixing frame 15 and the protective shell 1, preventing rainwater from entering the motor 16. The setting of the heat dissipation groove 6, because it is connected to the connecting groove 5, allows air to circulate, which can greatly reduce the impact of the protective shell 1 on the heat dissipation of the camera body 2.

[0024] Working Principle: When in use, the protective shell 1 and top cover 11 enclose the camera body 2, preventing direct contact with rainwater. The small hole 3, matched to the lens of the camera body 2, allows the lens to capture external images through the hole, utilizing the imaging principle of the small hole 3. This device is installed at the rear of the vehicle for rearward monitoring. During movement, air enters through the air inlet 4, flows through the connecting groove 5, and finally exits through the small hole 3, the first drainage groove 7, and the second drainage groove 8. Even if some water droplets enter the small hole 3, the airflow disperses the rainwater around and in front of the small hole 3, preventing further water ingress and achieving two-way waterproofing, thus solving the problem of water getting on the lens. When the vehicle is stationary, the first drainage groove 7 and the second drainage groove 8 also guide and drain the rainwater from the small hole 3, preventing further water ingress. With enhanced water resistance, when the top cover 11 and protective shell 1 are installed, the first sealing ring 1301 is inserted into the sealing groove 1302 to seal the gap between the top cover 11 and the protective shell 1, preventing rainwater from entering. The operation of the motor 16 can drive the protective shell 1 to rotate as a whole, thereby adjusting its monitoring angle. The connection cavity 18 and the wiring hole at the bottom of the protective shell 1 facilitate wiring of the camera body 2 inside the protective shell 1. The mounting groove 19 facilitates the installation of the base plate 14. The second sealing ring 17 seals the gap between the fixing frame 15 and the protective shell 1, preventing rainwater from entering the motor 16. The heat dissipation groove 6, connected to the connection groove 5, allows air circulation, greatly reducing the impact of the protective shell 1 on the heat dissipation of the camera body 2.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
