[0030] Such as Figure 1 and Figure 2As shown in the figure, a headlight control circuit board includes a circuit board body 100. Mounting holes 101 are provided at the middle edge and corners of the circuit board body 100. Protective rings 102 are fixedly connected to the end faces of the plurality of mounting holes 101. The connection between the plurality of protective rings 102 and the circuit board body 100 is set to be arc-shaped transition, which is convenient for installing and fixing the bolt 201. Under the protection of the protective ring 102, the circuit board body 100 can be installed and fixed. A plurality of wire holes 103 are provided at a position far from the middle of the circuit board body 100. The plurality of wire holes 103 are arranged in two groups in parallel, and each group of wire holes 103 has no less than three and is arranged at equal intervals. The two groups of wire holes 103 are symmetrically arranged at a position far from the middle of the circuit board body 100, which is convenient for the wire harness to pass through the plurality of wire holes 103 when the wire harness is soldered to the circuit board body 100, avoiding being exposed outside the circuit board body 100 in a messy manner, thus causing difficulties in later maintenance and inspection. A plurality of heat dissipation strips 104 are uniformly fixedly connected to the bottom of the circuit board body 100. The plurality of heat dissipation strips 104 are arranged at equal intervals, and the distance between the heat dissipation strips 104 is set between 1 mm and 2 mm, which is convenient for the plurality of heat dissipation strips 104 to quickly absorb and discharge the heat generated by the circuit board body 100.

[0031] As Figure 3 and Figure 4 As shown in the figure, an elastic connection part 200 is penetrated through the inside of each of the plurality of mounting holes 101. The elastic connection part 200 includes a bolt 201 and a protective part 203 sleeved on the outer wall of the bolt 201 near the bottom. A slot 202 is provided at the top of the bolt 201. Two inclined surfaces 202a are provided on the inner wall of the slot 202 near the end face. The two inclined surfaces 202a are centrally symmetric about the center of the slot 202, which is convenient for locking the bolt 201 through the slot 202 when the bolt 201 is rotated. The inclined surfaces 202a provided can prevent easy removal and avoid damage to the connection part caused by frequent disassembly. The protective part 203 includes two protective pads 203a and a plurality of elastic parts 203b arranged between the two protective pads 203a. The plurality of elastic parts 203b are all bent and radially equidistantly distributed between the two opposite protective pads 203a, which is convenient for driving the circuit board body 100 to squeeze the protective part 203 when the bolt 201 is rotated and locked, so that the two protective pads 203a squeeze the middle elastic parts 203b through the bent positions, and after being compacted, they can provide flexibility. The two protective pads 203a and the plurality of elastic parts 203b are all made of silicone rubber material, so that the protective pads 203a can provide a shock-absorbing effect during use, and through elastic compaction, they protect the circuit board body 100.

The circuit board body 100 is installed at a corresponding position through the bolts 201. While rotating the bolts 201, the circuit board body 100 squeezes the protective pad 203a on the protective frame 203, so as to bend the elastic part 203 at the bending position, so that the whole elastic part 203 is pressed firmly on the circuit board body 100 and the installation position. The elastic connection part 200 made of silicone rubber can protect the installation part of the circuit board body 100, prevent damage to the circuit board body 100 caused by over-tightening, and can pass through a plurality of wire holes 103 when burning the wire harness, ensuring the regularity of the wire harness and preventing the chaos from causing difficulties in later maintenance.
