New energy automobile charging pile with high safety

Abstract

The invention discloses a new energy automobile charging pile with high safety. The new energy automobile charging pile comprises a machine body and a charging gun head arranged at the bottom of the machine body. A containing cavity is formed in the bottom inside the machine body; sliding grooves are formed in the left and right sides of the containing cavity correspondingly; screws are arranged in the sliding grooves; and the top of the screws are in power connection with motors; a movable beam is arranged in the containing cavity, and the two side ends of the movable beam stretch into the sliding grooves and are connected with the screws in threaded fit mode; a connecting block is arranged at the bottom of the movable beam; the bottom of the connecting block penetrates through the bottom wall of the machine body and is connected with the bottom wall of the machine body in a sliding fit mode; first cavities are formed inside the connecting block in a bilateral symmetry mode; sink grooves are formed in the tops of the first cavities; an embedded groove is formed in the end face of the bottom of the connecting block; communicating holes are formed in the position, between the embedded groove and the first cavities, of the connecting block; second cavities are formed symmetrically in the outer side wall of each communicating hole; first sliding blocks are arranged in the first cavities; first springs are arranged between the tops of the first sliding blocks and the sink grooves; and sliding rods extending into the communicating holes are arranged at the bottoms of the first sliding blocks. The structure is simple, operation is convenient, and automatic locking can be achieved during charging.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle charging, in particular to a new energy vehicle charging pile with high safety. Background technique [0002] As a green transportation tool with broad development prospects, electric vehicles will be popularized at an extremely fast speed, and the future market prospects are also extremely huge. However, electric vehicles need to be charged through charging piles before they can continue to be used. Charging piles are installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, and can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is connected to the AC power grid, and the output end is equipped with a charging head for charging electric vehicles. The existing charging pile is bulky and occupies a lot of land, which limits its use, low...

AI Technical Summary

Problems solved by technology

The input end of the charging pile is connected to the AC power grid, and the output end is equipped with a charging head for charging electric vehicles. The existing charging pile is bulky and occupies a lot of land, which limits its use, low safety, and high cost. Moreover, in the process of charging the electric vehicle by the charging pile, pulling out the charging gun will cause a safety accident, causing casualties, equipment damage and even fire. lock, unlock after charging
