[0027] Two card slots 16 are provided on the surface of the rearview mirror housing 1, and the card slots 16 are respectively set up on the left and right sides. Reset springs 14 and card blocks 15 are installed inside the two protrusions of the mounting frame 5. The card blocks 15 are all set on the side close to the rearview mirror housing 1, and one end of the card block 15 passes through the mounting frame 5. A cover plate is provided on one side of the reset spring 14. When the rearview mirror housing 1 is installed, the rearview mirror housing 1 can be aligned with the mounting frame 5 and pushed onto the mounting frame 5, so that the card block 15 of the mounting frame 5 is stuck in the card slot 16 on the surface of the rearview mirror housing 1. During the installation process, the rearview mirror housing 1 will knock open the card block 15, and the card block 15 will shrink into the inside of the mounting frame 5. When the card slot 16 moves to the position of the card block 15, the card block 15 is reset by the elasticity of the reset spring 14, so that the card block 15 The installation of the mirror housing 1 is completed by being stuck in the card slot 16, and the mounting frame 5 is installed on the mounting rod of the car through the mounting hole 6 on the surface. The hook 12 on the surface of the rearview mirror housing 1 is welded to the rearview mirror housing 1, and the hook 12 is hung on the hanging ring 13 on the surface of the electric telescopic rod 9, and the hanging ring 13 is welded to the electric telescopic rod 9. When the car is started, since the surfaces of the mounting hole 6 and the mounting rod of the car are both provided with contacts, when the mounting hole 6 is installed on the mounting rod, the mounting hole 6 and the contacts of the mounting rod are in contact, so that the car can supply power to the second main board 11 inside the mounting frame 5 through the contacts of the mounting rod and the mounting hole 6. The electric telescopic rod 9 and the image sensor 8 are both installed on the mounting frame 5 with fixing bolts, and the electric telescopic rod 9 and the image sensor 8 are both connected to the second main board 11. Electrical connection, when the car is started and the image sensor 8 is powered on, the driver's image information will be collected. The image information includes the driver's height and is transmitted to the second main board 11 inside the mounting frame 5 in digital form. The second main board 11 analyzes and processes according to the algorithm, and transmits an electrical signal to the electric telescopic rod 9 by analyzing the driver's height in the image. The motor of the electric telescopic rod 9 is powered on to generate power, and the speed is converted into torque through the reducer. The reducer usually adopts gear transmission, so as to convert the high-speed rotation of the motor into the slow telescopic movement of the electric telescopic rod 9. The electric telescopic rod 9 is extended to the specified length according to the electrical signal transmitted from the second main board 11. Since the hook 12 on the surface of the rearview mirror housing 1 is installed on the hanging ring 13 on the surface of the electric telescopic rod 9, In this way, when the electric telescopic rod 9 is extended or retracted, the rearview mirror housing 1 will be driven to rotate, so as to achieve different viewing angles for the driver. When the angle adjustment is completed, the power port 3 on the top surface of the rearview mirror housing 1 is electrically connected to the car through a data cable, and the power port 3 is electrically connected to the first main board 10, so that the car can power the first main board 10. Since the two photosensitive sensors 7 are electrically connected to the first main board 10, the car can also power the photosensitive sensors 7. A fixing frame 4 is provided on one side of the electrochromic lens 2. The fixing frame 4 fixes the electrochromic lens 2 in the rearview mirror housing 1. The photosensitive sensor 7 on the side close to the mounting frame 5 will sense the light in front of the car. If it senses that it is dark in front of the front of the car, the photosensitive sensor 7 transmits information to the first main board 10.The first main board 10 transmits information to the photosensitive sensor 7 in the front, so that the photosensitive sensor 7 of the rearview mirror housing 1 away from the mounting frame 5 works and detects the light behind the vehicle body. When the rear light is sensed, the photosensitive sensor 7 away from the mounting frame 5 will transmit information to the first main board 10, and the first main board 10 transmits the electrical signal to the electrochromic lens 2. The structure of the electrochromic lens 2 is similar to a sandwich, which is composed of two parallel conductive glasses with a certain gap and an electrochromic material filled in the gap. When a small current is passed, the two conductive glasses form an electric field, causing the electrochromic material to produce an electrochemical effect to change color, realizing a transient change in the glass transmittance, thereby dimming. When the power is stopped, an oxidation reaction occurs inside the material and the glass recovers. Specific embodiment 2:
[0029] Reference Figure 1-7 , an intelligent dimming device for a rearview mirror of an automobile, further based on the basic structure in the specific embodiment 1, the card slot 16 can be replaced with a mounting hole 6, and the reset spring 14 and the card block 15 can be replaced with a fixing bolt 18, and two threaded holes 17 are provided on the surface of the mounting frame 5, and the position of the threaded hole 17 is consistent with the mounting hole 6, and the diameter of the mounting hole 6 is larger than the threaded hole 17. When installing, the fixing bolt 18 is screwed into the threaded hole 17, and one end of the fixing bolt 18 extends into the mounting hole 6, so that the rearview mirror housing 1 is installed on the mounting frame 5 through the fixing bolt 18. The specific parts are attached Figure 7 .
