[0030] Refer to Figures 1 to 3 , the present invention provides a vehicle-mounted camera device, including a camera 3, a light guide groove element 2, and a mounting bracket 4. The camera 3, the light guide groove element 2, and the mounting bracket 4 are all located inside the vehicle lamp. The camera 3 is fixedly installed inside the vehicle lamp through the mounting bracket 4. The light guide groove element 2 is a cylindrical part with openings at both ends. The rear end of the light guide groove element 2 is sleeved on the lens of the camera 3, and the front end abuts against the inner side of the light distribution mirror 1 of the vehicle lamp. The lens of the camera 3 obtains external information through the light guide groove element 2 and the light distribution mirror 1. That is, external light passes through the light distribution mirror 1 and then enters the lens of the camera 3 through the inside of the light guide groove element 2, and the camera 3 takes pictures accordingly. The front end of the light guide groove element 2 and the inner side of the light distribution mirror 1 can be connected or only abut against each other.

[0031] In the vehicle-mounted camera device of the present invention, the lens of the camera 3 obtains external light through the light guide groove element 2 and the light distribution mirror 1. The light guide groove element 2 can block part of the external light, so that the camera 3 can concentrate on obtaining the light in front of the vehicle lamp, and minimize the influence of the surrounding light on the shooting work of the camera 3. The camera 3 can more clearly shoot the scene in front of the lens, and the shooting effect is good. By adopting the method of installing the vehicle-mounted camera device inside the vehicle lamp, the space where the camera 3 is located has good sealing, little influence on the camera 3, which is beneficial to the shooting work of the camera 3, avoids dust accumulation on the lens of the camera 3, the installation environment is stable, the camera 3 is stably installed, is not easily collided, and does not affect the aesthetics of the whole vehicle. In addition, the installation process of the vehicle-mounted camera device is simple. Compared with installing on the vehicle windshield, it reduces the overall installation process of the vehicle.

[0032] As a preferred design, in this embodiment, refer to Figure 1 and Figure 2 , the light guide groove element 2 is in the shape of a square flare. The front end of the light guide groove element 2 is hermetically connected to the light distribution mirror 1. Preferably, the front end of the light guide groove element 2 and the light distribution mirror 1 are hermetically connected by welding or gluing. Among them, laser welding, friction welding, ultrasonic welding and other methods can be used for welding sealing. The rear end of the light guide groove element 2 is hermetically connected to the camera 3. Preferably, in this embodiment, a sealing ring is provided between the rear end of the light guide groove element 2 and the camera 3 for sealing. In this way, the lens of the camera 3 is in a more strictly sealed environment, further ensuring the shooting work of the camera 3.

[0033] As a preferred design, in this embodiment, refer to Figure 1 and Figure 2 , stripe protrusions 21 are provided on the inner wall of the light guide groove element 2, which can reduce the influence of external light irradiated on the inner wall of the light guide groove element 2 on the camera 3 and ensure the shooting quality. Preferably, the material of the light guide groove element 2 is black PC (polycarbonate) or PBT (polybutylene terephthalate) and other materials, which can have a certain adsorption effect on the light irradiated on the light guide groove element 2, further ensuring the shooting quality of the camera 3.

[0034] As a preferred design, in this embodiment, refer to Figure 3 , the vehicle-mounted camera device further includes an infrared night vision mechanism installed in the vehicle lamp. The infrared night vision mechanism includes an infrared LED light source and an infrared reflector 5. The infrared reflector 5 is located inside the light distribution mirror 1. When the infrared LED light source emits, the infrared light is reflected by the infrared reflector 5 and then emitted through the light distribution mirror 1. In this embodiment, the infrared LED light source is arranged on the circuit board 6, and the circuit board 6 is installed on the radiator 7 for convenient heat dissipation. In a dark environment, the infrared night vision mechanism is turned on to cooperate with the camera 3. The infrared LED light source emits infrared light, which is reflected by the infrared reflector 5 and then emitted through the light distribution mirror 1, irradiating the object in front of the vehicle lamp. After the infrared light is reflected by the object, it is acquired by the camera 3 again, so that the camera 3 can still work in the case of very dark light such as at night. Among them, the specific installation position of the infrared night vision mechanism can be adjusted according to the actual situation and can be installed beside the camera 3 inside the vehicle lamp. Of course, it can also be in a different vehicle lamp from the camera 3, as long as it is ensured that the infrared light emitted by the infrared night vision mechanism can ultimately be acquired by the camera.

[0035] The infrared night vision mechanism can be designed and used in the low beam mode (i.e., the infrared rays are projected in the vicinity in front of the vehicle lamp), or it can also be designed and used in the high beam mode (i.e., the infrared rays are projected far in front of the vehicle lamp). Preferably, the infrared reflector of the infrared night vision mechanism is a high beam reflector. In this way, by cooperating with the infrared mechanism through the camera 3, the scene in the distance can be captured, enabling the driver to detect the road conditions earlier at night and making driving more intelligent.

[0036] Since the cleaning condition of the light distribution mirror 1 in front of the camera 3 can affect the operation of the camera 3, preferably, a cleaning system can be equipped outside the vehicle lamp to clean the outer side of the light distribution mirror 1 and ensure the shooting operation of the camera 3.

[0037] As can be seen from the above, the vehicle-mounted camera device in this embodiment is installed inside the vehicle lamp, and through the sealed installation of the light guide groove element 2, the space where the camera 3 is located has good sealing, which is beneficial to the shooting operation of the camera 3; the working environment of the camera 3 is safe and stable, not easily subject to collision, and does not affect the aesthetics of the whole vehicle; the installation process of the vehicle-mounted camera device is simple. Compared with installing on the vehicle windshield, the overall installation process of the vehicle is reduced. In addition, through the cooperation with the infrared night vision mechanism, the vehicle-mounted camera device can also be used in an environment with very dim light, enabling the driver to detect the road conditions in time and making driving more intelligent.

[0038] The present invention also provides a vehicle lamp, which includes the light distribution mirror 1 and also includes the above-mentioned vehicle-mounted camera device. By adding the vehicle-mounted camera device, the functions of the vehicle lamp are increased, the overall value of the vehicle lamp is improved, and the market competitiveness is increased.

[0039] In summary, the invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0040] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
