[0026] The millimeter-wave radar 2 and the camera 1 are all connected to the frame 6 by threaded connection, the LED light source 4 is welded on the PCB board 3, the bottom shell 5 is provided with four threaded holes connected to the frame 6, the frame 6 is provided with threaded holes for placing the camera 1 and the millimeter-wave radar 2, and the bottom of the frame 6 is provided with four threaded holes connected to the bottom shell 5;

[0027] The lens 7 is connected to the frame 6 by bonding, which can avoid sharp edges and provide good sealing to prevent dust and water vapor from entering.

[0028] The structural order from top to bottom is lens 7, PCB board 3 and LED light source 4, frame 6, millimeter wave radar 2 and camera 1, and finally bottom shell 5.

[0029] Working principle: When the front ceiling light is turned on, the LED light source 4 is powered by the vehicle system's own power supply or battery, and the light of the LED light source 4 is irradiated through the lens 7 to achieve the lighting effect. When the person in the car gets out of the car, the millimeter wave radar 2 transmits millimeter wave signals of specific frequency and power into the car through the transmitter. These signals propagate in a straight line in the car. When they touch a person or object, the camera 1 will start taking pictures and upload them to the owner's mobile phone.

[0030] The advantage of the utility model is that when the vehicle is turned off and locked, the millimeter wave radar 2 can start a cycle to detect whether there are any signs of life in the vehicle. If there are still signs of life in the vehicle, the camera 1 will take a photo of the person still in the car and upload it to the owner's mobile phone.

[0031] The camera 1 is composed of two shells, which are connected and fixed by two screws, and two ears with threaded holes are arranged on both sides, and a receiving port of an image sensor is arranged below.
