Underground alternating current charging pile for electric vehicle

Abstract

The invention provides an underground alternating current charging pile for an electric vehicle. The underground alternating current charging pile for the electric vehicle comprises a charging pile main body. The charging pile main body is fixedly arranged on a wall of an underground garage. One side of the charging pile main body is provided with a first wire wheel by a wheel frame and a torsionspring. One side of the charging pile main body is provided with a T-shaped rail. The T-shaped rail is installed on the wall through the fixing device. An opening is formed in the T-shaped rail. A plurality of T-shaped blocks are installed in the T-shaped rail. The distance between two adjacent T-shaped blocks is equal. The T-shaped blocks can slide along the T-shaped rail correspondingly. A firstrack is installed on the lower portion of the T-shaped rail. The bottom surface of the T-shaped blocks is fixedly connected with the top surface of the first rack. A through hole is formed in the oneside of a vertical block of each T-shaped block. All the through holes are arranged outside the T-shaped rail. The central lines of the through holes are collinear. According to the mutual fit of a second wire wheel, a cotton rope, an inverted-L-shaped rod and a contact switch, so that the charging pile main body enters into the shutdown state when no one using, the consumption of electricity isgreatly reduced, and the energy is saved.

Description

technical field [0001] The invention belongs to the field of charging devices, in particular to an underground AC charging pile for electric vehicles. Background technique [0002] Due to the increase in the number of electric vehicles, the requirements for the safe and stable operation of urban power grids are also getting higher and higher. At present, a large amount of social capital is involved in the construction and operation of charging piles. Charging piles are divided into two types: AC charging piles and DC charging piles. The single-phase or three-phase alternating current is converted into direct current by the on-board charger to charge the on-board battery. The power is generally small and the charging speed is generally slow, so it is generally installed in the parking lot of the community and other places. However, the existing AC charging piles are usually set on the ground, and the charging wires are also scattered on the ground, which greatly troubles peop...

Problems solved by technology

However, the existing AC charging piles are usually set on the ground, and the charging wires are also scattered on the ground, which greatly troubles people's daily use, and the charging piles are still working when no one is using them, which consumes a lot of power and is not conducive to energy. sustainable development
