Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and more specifically, to a charging pile with a universal mainboard. Background Art

[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on the wall and installed in parking lots or charging stations in public buildings and residential areas. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding operations such as charging method, charging time, and cost data printing. The charging pile display can display data such as charging amount, cost, and charging time.

[0003] Patent authorization announcement No. CN213472822U discloses a charging pile mainboard circuit with Internet of Things function, including a junction box, support rods are bolted on all four sides of the bottom of the inner cavity of the junction box, a groove is opened at the center of the bottom of the inner cavity of the junction box, and the inner cavity of the groove is clamped with a circuit board, and fixing seats are bolted on both sides of the bottom of the inner cavity of the junction box. Through the cooperation of heat sinks, thermal conductive silicone and thermal conductive gaskets, the heat generated on the surface of the circuit board can be quickly absorbed and quickly transferred into the air, thereby quickly dissipating the heat of the circuit board. Through the cooperation of ventilation pipes and air outlets, users can use natural wind to cool the surface of the circuit board, and at the same time accelerate the air flow speed in the junction box, further improve the heat dissipation speed of the circuit board, and at the same time extend the service life of the circuit board, solving the problem of poor heat dissipation effect of the traditional charging pile mainboard circuit with Internet of Things function.

[0004] However, the junction box in patent authorization announcement number CN213472822U has fixed mounting holes for installing circuit boards, so only circuit boards of fixed sizes can be installed in the junction box. Therefore, circuit boards of different sizes need to match different junction boxes, which increases the production cost to a certain extent. Therefore, we propose a universal charging pile for motherboards to solve the above problems. Utility Model Content
