Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage charging piles, in particular to a high-voltage charging module of a high-voltage charging pile. Background Art

[0002] A high-voltage charging pile charging module is a device used to provide high-voltage power to quickly charge electric vehicles. This module usually includes components such as a high-voltage charger, a charging interface, and a control system, and can convert the AC power in the power grid into DC power suitable for charging electric vehicles. The charging module of the high-voltage charging pile has the characteristics of fast charging speed, high efficiency, safety and reliability. It is an important part of the charging infrastructure of electric vehicles. The charging module inside the high-voltage charging pile needs to be connected to the external high-voltage line for energy transmission. When the charging module on the high-voltage charging pile is affected by the use time, a large amount of heat is generated. Usually, the heat is dissipated to protect the charging module from being damaged by high temperature. However, the cooling fan used for heat dissipation will bring in a lot of dust with the wind speed discharged or sent out. On the one hand, the dust will have a certain impact on the equipment, and on the other hand, it will also have a certain impact on the cooling effect of the cooling fan itself. In order to avoid this phenomenon, a dustproof plate is usually installed at the cooling fan to reduce the entry of dust. However, the installation of the dustproof plate is particularly important. The more complicated the disassembly and assembly of the dustproof plate, the more it will affect the frequency of maintenance and cleaning of the dustproof plate in the later stage. At the same time, the worse the effect of the dustproof plate, the more it will directly affect the heat dissipation effect of the charging module, thereby reducing the use effect of the high-voltage charging column and affecting the durability and operation stability of the high-voltage charging pile.

[0003] Therefore, it is necessary to develop a high-voltage charging module for a high-voltage charging pile. Utility Model Content

[0004] The utility model aims to provide a high-voltage charging module of a high-voltage charging pile. The plug and the spring are provided. The plug is matched with the limit column to be slidably installed in the mounting hole of the mounting plate, and the spring is matched with the limit column. The spring has the effect of elastic reaction force, so that when the dustproof plate is pushed into the interior of the mounting frame, it will squeeze the plug. When the plug moves to the slot, the spring is free of pressure, and the plug is pushed to be inserted into the slot on the mounting frame, so that the dustproof plate can be installed and fixed. At the same time, one end of the plug is in an arc shape, which is convenient for applying a little force to pull out the dustproof plate. No tools are required during the process, and the dustproof plate is easy to disassemble and assemble, which improves the maintenance and cleaning efficiency of the dustproof plate. The effect of the dustproof plate is guaranteed, and the dustproof plate directly affects the overall heat dissipation effect of the high-voltage charging module as much as possible. The use effect of the high-voltage charging pile is effectively improved, and the durability and operation stability of the high-voltage charging pile are also effectively improved, so as to solve the problem that the high-voltage charging module on the high-voltage charging pile is easily affected by the poor heat dissipation effect of the dustproof plate, which directly affects the operation stability and durability.
