Protection structure for charging pile interface of fast charging station

Abstract

The invention discloses a protection structure for a charging pile interface of a fast charging station. The protection structure comprises a shell and a cover plate, wherein clamping posts are fixedat two ends of the cover plate; a baffle plate is arranged at the bottom of a movable end of the cover plate; the shell is correspondingly provided with clamping seats matched with the clamping postsand a rectangular groove capable of being matched with the baffle plate; a spherical cavity for movement of the end part of one clamping post is formed in each clamping seat; a plurality of fan-shapedgrooves are formed in an inner wall of each spherical cavity; a clamping block is arranged in each fan-shaped groove in a sliding manner and is connected with the bottom of the fan-shaped groove through a spring; when the pressing speed of the cover plate is too high, the bottom ends of the clamping posts violently collide with the bottoms of the spherical cavities, so that the clamping posts andthe spherical cavities are damaged; and after the end parts of the clamping posts are in contact with the upper surfaces of the clamping blocks at the bottoms of the corresponding spherical cavities,the springs are compressed and then generate elastic force opposite to the direction of pressing force to buffer the impact on the clamping blocks, so that the target of protecting the internal structures of the clamping seats is achieved.

Description

technical field [0001] The invention relates to a charging pile, in particular to a protection structure for a charging pile interface of a fast charging station. Background technique [0002] Faced with a large number of electric vehicles, the battery life is very limited due to the use of lead-acid batteries or lithium batteries. Usually, it must be charged after driving for one to three days, and it often happens that the electric vehicles are parked due to insufficient power on the road. The phenomenon of promotion, so the electric vehicle charging pile came into being. However, at present, there is no standard charging place for electric vehicle charging in almost all residential areas. Basically, the charging is carried out by putting wires from the outer wall of the building to the first floor of each household, and connecting them privately, which greatly increases the safety and reliability of power use. The rate of safety accidents increases accordingly; and the e...

However, at present, there is no standard charging place for electric vehicle charging in almost all residential areas. Basically, the charging is carried out by putting wires from the outer wall of the building to the first floor of each household, and connecting them privately, which greatly increases the safety and reliability of power use. The rate of safety accidents increases accordingly; and the existing outdoor charging piles are seriously affected by external environmental factors. Usually, in rainy days or on special road sections, there will be water or a large amount of dust at the interface of the charging piles, causing the charging piles to be damaged. The service life of the charging pile is reduced, and in severe cases, it will cause a short circuit or even direct damage to the charging pile
