[0002] In the context of the rapid development of automotive intelligence and personalization, traditional side flag decorative parts are no longer able to meet consumers' dual requirements for functional integration and aesthetics. In the prior art, side flags generally integrate a single function, such as decoration, ambient light, camera, or autonomous driving indicator. Although some products have achieved function combination, there are still problems such as incomplete functions, fragmented appearance, complex structure, and high cost, making it difficult to adapt to the diverse market demands.
[0003] The prior art CN214745484U discloses a car logo lamp. The technical solution discloses that "the present invention discloses a car logo lamp, including an outer housing, an inner housing, an LED circuit board, a refractive film, and a lamp cover. The inner housing and the lamp cover enclose a cavity structure. The LED circuit board and the refractive film are located in the cavity structure. The connecting wire of the LED circuit board passes through the inner housing and is electrically connected to an external power supply. The outer housing wraps around the outer periphery of the inner housing and is connected to the vehicle body. The lamp cover includes a light-transmitting area and a non-light-transmitting area. The light-transmitting area is shaped to be similar to the refractive film and protrudes outward from the lamp cover to form a trapezoidal end face. The non-light-transmitting area is formed by covering the outside of the lamp cover with a decorative film. In the car logo lamp of the present invention, the light-transmitting area on the lamp cover protrudes outward to form a trapezoidal end face structure. The protruding light-transmitting area makes the car logo shape more prominent. The trapezoidal end face structure can divide the light into multiple refraction areas, thus avoiding direct light from causing visual discomfort to pedestrians." Although the prior art has disclosed a car logo lamp, there are still some deficiencies. Specifically, in the actual use process, this car logo lamp still has deficiencies in functional integration and adaptability. This car logo lamp fails to achieve multifunctional integration such as autonomous driving indication, camera integration, and ambient light interaction. There is no corresponding protection device outside the car logo lamp, and the function of the product is single, making it difficult to meet the requirements of intelligent vehicles for diversified external signals and interactive displays.

[0022] Working principle of the present invention: When the vehicle starts, the control system controls the operation of the motor 23. The motor 23 drives the first gear 25 to rotate. The first gear 25 drives the second gear 26 to rotate. The second gear 26 drives the rack 28 to move. The rack 28 drives the protective cover 21 to move into the headlight. The camera 11 detects that the upper end of the protective cover 21 moves to the position just in contact with the guide groove 22, and the motor 23 stops operating. The vehicle body power supply supplies power to the lamp panel 5 through the wire harness 10. The color light-emitting lamp group on one side of the lamp panel 5 emits colored light. The colored light is concentrated by the condenser bowl structure at the bottom of the light distribution lens 4 and diffused through the top diffusing texture to create a welcome appearance effect. When the vehicle is in autonomous driving, the ice blue lamp group on the other side of the lamp panel 5 emits ice blue light to realize the function of the autonomous driving indicator light. The camera 11 continuously collects the vehicle side image signal to assist the autonomous driving system. When the lamp panel 5 emits light during operation, heat is generated. The heat is transferred to the heat sink 8 through the thermal conductive silicone 6. The heat sink 8 dissipates the heat into the air.
[0023] When the vehicle shuts down, the control system controls the operation of the motor 23. The motor 23 drives the first gear 25 to rotate. The first gear 25 drives the second gear 26 to rotate. The second gear 26 drives the rack 28 to move. The rack 28 drives the protective cover 21 to move along the guide groove 22. The upper end of the protective cover 21 moves to the inside of the support plate 20 to seal the camera 11. The nozzle 30 sprays cleaning liquid onto the surface of the camera 11. The piezoelectric vibrator 29 cleans the surface of the camera 11 through high-frequency vibration. After the camera 11 detects that there is no foreign object on the surface, the nozzle 30 and the piezoelectric vibrator 29 stop operating.
