The control circuit 5 runs through the wiring groove 3. The support block 6 and the first sealing ring 7 are both of annular design. When using the device, first fix the board body 4 on the surface of the mounting base plate 2 so that the control circuit 5 passes through the wiring groove 3 for installation. Then, the protective shell 1 and the mounting base plate 2 are threadedly connected so that the support block 6 presses the first sealing ring 7 against the surface of the mounting base plate 2 to improve the sealing performance.

After the protective shell 1 and the mounting base plate 2 are connected, the limit block 8 on the inner wall of the protective shell 1 pushes the linkage slide plate 9 down, so that the linkage slide plate 9 compresses the spring while driving the first piston column 10 to slide.
[0033] A wiring groove 3 is provided on the surface of the mounting base plate 2, and a board body 4 is installed on the surface of the mounting base plate 2. A control circuit 5 is fixedly connected to the lower surface of the board body 4.

The soft material of the buffer pad 15 fits on the surface of the board body 4 to prevent external impact from causing damage to the board body 4 and prevent the board body 4 from shaking, thereby improving the practicability of the device.
[0036] Working principle: When using the protective structure for the day mirror control board with wiring sealing function, first fix the board body 4 on the surface of the mounting base plate 2, so that the control line 5 passes through the wiring groove 3, and connect the protective shell 1 and the mounting base plate 2 through threads, so that the support block 6 pushes the first sealing ring 7 against the surface of the mounting base plate 2, and at the same time, the limit block 8 pushes the linkage slide plate 9 and the first piston column 10 to slide, so that the first piston column 10 inflates the sealing airbag 11, so that the sealing airbag 11 expands and seals, and pushes the second piston column 12 through the protective shell 1, so that the second piston column 12 pushes the air to the third piston column 13, and the third piston column 13 drives the sealing claw 14 to slide to limit the control line 5. During operation, the board body 4 is limited and buffered by the buffer pad 15, and the shaking damage is reduced, thereby increasing the overall practicality.
