Charging device with plug protection function for new energy automobile

Abstract

The invention relates to a charging device with a plug protection function for a new energy automobile, comprising a main body, a wire, a plug, a PLC and a protection mechanism. The main body is provided with a card slot and a wire reel. The wire is provided with a fixing mechanism. The protection mechanism comprises a separating unit and a lifting unit, wherein the separating unit comprises a knob, a transmission shaft, a first gear, a second gear, a first screw rod, a nut and a plurality of swinging components, and the fixing mechanism comprises a fixing block and a plurality of adsorption units. The charging device with the plug protection function for the new energy automobile can prevent rainwater and dust from entering the inside of the plug and prevent short circuit of the electronic components inside the plug or poor contact between the plug and the charging socket of the electric vehicle through the protection mechanism, and enable the plug and the wire to be fastened on the surface of the electric vehicle and prevent the plug from being separated from the charging socket of the electric vehicle through the fixing mechanism.

Description

technical field [0001] The invention relates to the field of charging piles for new energy vehicles, in particular to a charging device with a plug protection function for new energy vehicles. 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. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging methods, charging time...

AI Technical Summary

Problems solved by technology

[0003] However, the plugs of existing charging piles are generally exposed in the air, and rainwater can easily enter the plug, causing a short circuit of the electronic components inside the plug, and dust in the air will also enter the plug, causing the plug to charge the electric vehicle. The poor contact between the sockets affects the charging efficiency of the existing charging piles. Not only that, the plugs of the existing charging piles cannot be effectively fastened to the electric vehicle, making the plug easily separated from the electric vehicle
