Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of charging piles, and specifically to an electric vehicle charging pile. Background Art

[0002] Charging stations function similarly to gas pumps at gas stations. They can be fixed to walls and installed in public buildings (such as public buildings, shopping malls, and public parking lots), residential parking lots, or charging stations. They can charge various models of electric vehicles at different voltage levels. The input of the charging station is directly connected to the AC power grid, and the output is equipped with a charging plug for charging electric vehicles. Users can use a specific charging card by swiping it through the human-computer interaction interface provided by the charging station to select the corresponding charging method, charging time, and cost data. The charging station display can display data such as charge level, cost, and charging time.

[0003] When a traditional car charging station experiences an internal electrical component failure, the entire station must be removed from the wall and the faulty component replaced. To improve the ease of car charging station maintenance, a Chinese patent application, publication number "CN109050336A," provides a moped charging station with a charging station panel equipped with a main control core board. The panel is connected to a clip, and the charging station housing is equipped with a lock that matches the clip, facilitating repair and maintenance.

[0004] While this moped charging station improves maintenance convenience, the internal circuit boards are not very secure. For example, cracks in the panel displaying the human-machine interface and loose connections between the clips and cable leads to gaps between the panel and the housing. These conditions can easily allow rain and dust to reach the circuit boards, potentially causing electrical failures.

[0005] Therefore, how to improve the safety of the internal electrical components of electric vehicle charging piles while ensuring maintenance convenience has become a technical problem that needs to be solved urgently. Utility Model Content
