Description
Technical Field
[0001] This utility model relates to the field of automotive electronics, and in particular to an integrated vehicle-mounted camera module structure. Background Technology
[0002] An integrated vehicle camera is a camera device integrated into a car. Its structure includes a lens, an image sensor, and a signal processing circuit. When it is powered on, the image sensor converts the light signal into an electrical signal. The signal processing circuit processes the signal and converts it into a digital image signal, which is then transmitted to the central control display screen, etc., via wired or wireless means for the driver to view. In the fields of driving assistance and safety monitoring, forward-looking cameras are used to assist in automatic emergency braking, and surround-view cameras form a panoramic surround-view system to assist in parking and monitor the status of the driver and passengers.
[0003] Early integrated automotive cameras originated from the introduction of camera technology into the automotive industry. However, their application in automobiles was not mature and the cost was high. They consisted of an optical lens, an image sensor, and an image signal processor. During operation, light was reflected and refracted into the lens and then into the sensor, where it was converted into analog and digital electrical signals, and finally the processor output the image. They suffered from weak computing power, slow image processing, and were also affected by bad weather and lighting conditions. Furthermore, they had limited field of view and blind spots. Current integrated automotive cameras consist of an integrated panel, PCB assembly, and back cover. They can improve computing power and image processing speed by using high-performance ISPs and chips. They can also achieve multi-camera fusion, use fisheye or ultra-wide-angle lenses, and realize dynamic viewing angle adjustment. However, after prolonged use, existing integrated automotive cameras still suffer from dust accumulation on the lens surface and fogging and blurring due to humidity changes. Utility Model Content

[0039] Reference Figure 1 , Figure 2 and Figure 5 A storage box 19 is slidably connected to the upper part of the inner wall of the dust collection box 6. The inner wall of the storage box 19 is rounded to facilitate dust cleaning. The storage box 19 is used to store the dust collected by the dust collection box 6 and can be replaced periodically. An infrared camera 20 is fixedly connected to the bottom of the inner wall of the inner shell 10. The infrared camera 20 is used to assist in shooting in special situations at night. The right side of the infrared camera 20 is fixedly connected to the lens 9, which protects the infrared camera 20. A shield 18 is fixedly connected to the upper right side of the outer shell 1.

The slide rail 17 is slidably connected to the outer shell 1.
[0040] Specifically, a storage box 19 is slidably connected to the upper part of the inner wall of the dust collection box 6. The storage box 19 is used to store the dust collected by the dust collection box 6 and can be replaced periodically. An infrared camera 20 is fixed to the inner wall of the inner shell 10 for auxiliary shooting in special situations at night. A shield 18 is set above the wax box 7 to reduce the influence of strong light on the shooting. A slide rail 17 is fixedly connected to the outer wall of the metal shell 16 to facilitate the rotation of the inner shell 10 by the metal shell 16 and to limit the range of rotation. It is matched with the servo motor 12 for reciprocating rotation.
[0041] Working principle: Before using the device, the inner shell 10 is rotated by the servo motor 12. The lens 11 and infrared camera 20 are fixedly connected to the middle of the inner wall of the inner shell 10. When the inner shell 10 rotates from the recessed semi-circular space of the outer shell 1 to the surface, the lens 9 rotates synchronously with the inner shell 10. During the rotation, it rubs against the wax block 8 wrapped in the wax box 7, and the wax on the lens 9 is spread evenly by the brush 4 on the front side of the brush holder 3 to prevent water droplets from sticking to the surface of the lens 9 due to humidity, which would affect the lens 11 in collecting imaging information. When the inner shell 10 rotates back to the recessed semi-circular space, the lens 9 comes into contact with the scraper 5 on the brush holder 3. The dust on the lens 9 is scraped off by the scraper 5 and collected in the dust collection box 6 through the top of the dust collection box 6.
[0042] Chip 201 is tightly connected to heat absorber 202 via thermal grease. Heat generated by chip 201 is transferred to heat absorber 202 and then received by conductor 203. Conductor 203 is designed with multiple heat sinks and a circular copper tube. The circular copper tube is filled with liquid nitrogen, and efficient heat transfer is achieved through the circulation of liquid nitrogen. The heat is then transferred by conductor 203 to heat sink 204, and finally transferred to the air in heat sink 208 via heat sink 204. In order to accelerate the heat dissipation process, servo motor 205 installed in air outlet 207 drives fan blade 206 to rotate and blow air to the left side of heat sink 208, so that the air in heat sink 208 flows to the left, effectively carrying away hot air and ensuring the overall heat dissipation effect.
