A new type of buried electric vehicle charging pile

Abstract

The invention relates to a new type of buried electric vehicle charging pile, which includes a charging pile body, and the charging pile body is additionally provided with a charging unit and a pre-embedded protection unit, wherein the pre-buried protection unit includes a pre-embedded box, a terminal, a positioning chute, an electrical The heating wire, the semiconductor refrigeration mechanism, the leakage protector, the overload protector and the control circuit, the charging unit includes the bearing column, the bearing beam, the charging terminal, the sealing protective cover and the charging control circuit. On the one hand, the present invention can improve the environmental practicability of the charging pile equipment, reduce the site cost during construction and use, and improve the safety of the charging pile equipment operation; on the other hand, it can effectively increase the number of effective charging ports of the charging pile equipment, thereby It greatly improves the working efficiency of the charging operation of charging pile equipment. In addition, according to the needs of use, it can flexibly realize the network operation among multiple charging pile equipment to further improve the efficiency of charging operation.

Description

technical field [0001] The invention relates to a charging pile, in particular to a novel underground electric vehicle charging pile. Background technique [0002] Charging piles are currently one of the important tools for charging electric vehicles and other equipment. They are used in a huge amount. However, in actual use, it is found that the current charging pile equipment often adopts the traditional structure. Although it can meet the needs of charging operations, its In the process of construction and use, it needs to be directly exposed to the outdoors, and a large area of ​​open space is required for supporting use. On the one hand, the construction and operation of charging pile equipment are subject to site constraints, high cost, and insufficient space utilization. On the one hand, the charging pile equipment is extremely vulnerable to external impact, exposure, corrosive liquid erosion and solid pollutant pollution, which seriously affects the stability and rel...

[0002] Charging piles are currently one of the important tools for charging electric vehicles and other equipment. They are used in a huge amount. However, in actual use, it is found that the current charging pile equipment often adopts the traditional structure. Although it can meet the needs of charging operations, its In the process of construction and use, it needs to be directly exposed to the outdoors, and a large area of ​​open space is required for supporting use. On the one hand, the construction and operation of charging pile equipment are subject to site constraints, high cost, and insufficient space utilization. On the one hand, the charging pile equipment is extremely vulnerable to external impact, exposure, corrosive liquid erosion and solid pollutant pollution, which seriously affects the stability and reliability of the charging pile operation. In addition, the current charging pile equipment is often There are 2-4 charging guns installed on the side surface of the charging pile equipment to charge the vehicle, which seriously affects the efficiency of the charging operation. At the same time, the current charging pile equipment needs to operate independently during operation, which cannot According to the needs of use, realize the online operation of multiple charging pile devices to meet the needs of high-power charging, which seriously restricts the flexibility and reliability of charging pile operation, and also seriously affects the efficiency of charging operations. Therefore, In response to this situation, it is urgent to develop a new charging pile equipment structure to meet the needs of actual use
