Electric vehicle charging pile capable of being automatically powered off when being impacted

Abstract

The invention relates to the technical field of charging piles, and discloses an electric vehicle charging pile capable of being automatically powered off when being impacted. The electric vehicle charging pile comprises a base, the top of the base is fixedly connected with a fixed cylinder, the top of the fixed cylinder is fixedly connected with a fixed seat, and the outer part of the fixed cylinder is inserted with eight annularly arranged extrusion rods; and the outer parts of the eight extrusion rods are all connected with damping springs, the opposite sides of the eight extrusion rods are all fixedly connected with top plates, the outer parts of the eight top plates are connected with rubber rings, a movable rod is inserted into the top of the fixed seat, the bottom of the movable rod is fixedly connected with a wedge-shaped block, and the top of the movable rod is rotatably connected with two connecting rods. When a vehicle collides with the charging pile, the extruded side of each rubber ring drives the extrusion rods to move in the direction close to the wedge-shaped block through a top plate, the damping springs are compressed, the impact force of the vehicle on the charging pile is counteracted through elastic buffering of the rubber rings and the damping springs, and the vehicle and the charging pile are prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a charging pile for electric vehicles that can automatically cut off power when hit. Background technique [0002] The function of the charging pile is similar to the refueling machine in the gas station. It can be fixed on the ground or wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations. Charge all models of electric vehicles. [0003] The existing charging pile fixed on the ground requires the owner to park the car next to the charging pile when charging the car. When parking, the owner is easily distracted or makes an operation error, causing the vehicle to hit the charging pile, which may damage the charging pile or even leak electricity. It is very dangerous for the owner or the person next to the charging pile to be electrocuted when the current is transmitted t...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a charging pile for electric vehicles that can automatically cut off the power when it is hit. It has the advantages of automatically cutting off the power and reminding the owner when it is hit. It is easy to damage the charging pile or even leak electricity. When the current is transmitted to the car, it is easy to cause electric shock to the owner or the person next to the charging pile. It is a very dangerous problem.
