[0002] Charging pile refers to the charging device that provides energy for electric vehicles. Its function is similar to the gas pump in the gas station. The circuit board is one of the main components of the charging pile. It is mainly responsible for control, protection, communication, display and other functions. It is the basis for the operation of the entire charging pile system.

[0003] In the hot weather in summer, the temperature is high and the surface temperature of the charging pile will be even higher. Running the charging pile for a long time may cause the components on the circuit board to continue to heat up, resulting in an increase in temperature. Existing charging piles usually only design overall heat dissipation measures for the charging piles, and do not design separate heat dissipation measures for the circuit board, which may cause the components on the circuit board to age, fail or burn out under high temperatures, thereby causing the performance of the components on the circuit board to decline, thereby affecting the performance of the charging pile, causing the charging pile to fail to work normally, and shortening the service life of the charging pile. Utility Model Content

[0029] Further examples:

[0030] Please refer to Figures 4 to 6As shown, the buffer mechanism 6 includes a fixed column 601, a circular groove 602 is formed on the top of the fixed column 601, a magnet 1 603 is arranged at the bottom of the circular groove 602, a magnet 2 605 is slidably installed inside the circular groove 602, a trigger cylinder 604 is arranged on the top of the magnet 2 605, the magnet 1 603 and the magnet 2 605 have the same magnetic properties, and the two repel each other, which is used to absorb the impact force caused by the external environment on the circuit board; wherein, the cross section of the trigger cylinder 604 is n-shaped, which is used to limit the up and down movement range of the circuit board, and the trigger cylinder The cross-section of the connection between 604 and the second magnet 605 is a convex structure, and the cross-section of the annular groove 602 is a concave structure, and the two are adapted to each other, which is used to prevent the trigger tube 604 from being separated from the annular groove 602; wherein, a telescopic spring 606 is arranged between the bottom of one side of the trigger tube 604 located outside the annular groove 602 and the bottom of the fixed column 601, and the telescopic spring 606 is sleeved on the outer surface of the fixed column 601, and the telescopic spring 606 can further absorb the impact force exerted on the circuit board, thereby improving the shock absorbing effect on the circuit board.

[0031] Everything in the above example works like this:

[0032] When in use, the worker first fixes the installation box 1 in the charging pile through the installation hole 5, then aligns the hole on the circuit board with the fixing column 601 inside the installation box 1, and then the worker fixes it on the fixing column 601 with screws; in hot summer weather, the temperature inside the installation box 1 gradually rises, and the surface temperature of the circuit board also rises accordingly. When the temperature around the circuit board reaches the set temperature, the temperature sensor 8 outputs an electrical signal to the fan 701 and controls the circuit that connects the fan 701. At this time, the fan 701 starts to rotate and absorbs the hot air at the bottom of the circuit board through the suction pipe 703, and the area near the circuit board is in a low pressure state. Then, air is inhaled from the vent 2 4 on the upper part of the circuit board, and then flows to the exhaust box 704 through the suction box 702, and then is discharged from the inside of the air inlet 1 to the outside of the installation box 1 through the exhaust pipe 705, thereby realizing independent heat dissipation measures for the circuit board, avoiding the aging and failure of the components on the circuit board caused by long-term high-temperature operation, thereby stabilizing the usability of the circuit board. The performance of the charging pile is more stable and the service life of the charging pile is increased. When the charging pile is impacted from the outside, the installation box 1 is subjected to force and vibrates, and the fixed column 601 inside the installation box 1 also vibrates. At this time, the circuit board drives the magnet 1 603 to slide along the inside of the annular groove 602 through the trigger tube 604, and the magnet 1 603 and the magnet 2 605 are close to each other. At the same time, the other side of the trigger tube 604 is gradually close to the bottom of the fixed column 601, and the telescopic spring 606 between the two gradually shrinks. According to the principle of magnetic repulsion, the magnet 2 605 at the bottom of the annular groove 602 pushes the magnet 1 603 to slide along the inside of the annular groove 602 to the outside, and then the telescopic spring 606 loses pressure and gradually stretches, and cooperates with the magnet 1 603 to push the trigger tube 604 away from it, which can absorb and buffer external vibration and impact, thereby reducing the direct impact on the circuit board and improving its vibration resistance. At the same time, it can also enhance the stability of the circuit board, making it more stable and reliable during operation, reducing the failure rate, and thus extending its service life.
