[0007] Preferably, the movable component includes a motor fixed in the connecting block, the output shaft of the motor is fixedly connected with an incomplete gear, the incomplete gear is located in the movable frame, and a toothed plate meshing with the incomplete gear is fixedly connected to the inner wall of the movable frame.
[0008] Preferably, telescopic rods are fixedly connected to both sides of the movable frame, and the other ends of the telescopic rods are fixedly connected to the connecting blocks.
[0009] Preferably, the fixing assembly comprises a first magnetic plate connected and fixed to the middle of the movable frame, and two second magnetic plates magnetically matched with the first magnetic plate are fixedly connected in the connecting block.
[0010] Preferably, the end of the infrared camera is connected to the connecting block via an electric wire to ensure the operation of the active infrared camera.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The incomplete gear of the utility model rotates slowly and continuously, acting on two tooth plates to make the movable frame and the movable rod reciprocate, and cooperates with the sliding groove to make the rotating cylinder reciprocate at a certain angle, so that the collection area of the infrared camera moves to collect the driver's face.
[0013] When the teeth of the incomplete gear are disengaged from the upper tooth plate and have not yet engaged with the lower tooth plate, that is, when the rotating cylinder is rotating in the reverse direction, the first magnetic plate approaches one of the second magnetic plates and is magnetically connected to it, thereby ensuring the stable position of the movable frame and the rotating cylinder and ensuring that there is a gap residence time during the rotating cylinder's reversal process.

When the car is driving, the motor 7 runs slowly, the incomplete gear 8 rotates slowly and continuously, and the latching teeth of the incomplete gear 8 first contact the tooth plate 9 located above the movable frame 6, driving the movable frame 6 to move, and then the latching teeth of the incomplete gear 8 are disengaged from the tooth plate 9 above and meshed with the tooth plate 9 below, so that the movable frame 6 moves in the direction, so that the movable frame 6 reciprocates, and the telescopic rod 10 is adaptively extended and retracted to ensure the smooth reciprocating movement of the movable frame 6;
