Protection device for safe charging of electric automobile

Abstract

The invention discloses a protection device for the safe charging of an electric automobile. The protection device comprises a charging pile shell, a display screen, a connector sealing groove body, acharging connector, an anti-collision fence, a sliding way, a pushing air cylinder, a shielding plate, a luminosity sensor, an illuminating lamp, a pulley, a filter screen, an exhaust fan, an air blower, a heater, an electric appliance mounting frame, a controller, a mainboard, a charger, a temperature sensor and a humidity sensor. The beneficial effect is that, the unrepairable damage phenomenonis effectively avoided. the charging connector is not easy to age, and the service life of the charging connector is long; the charging port is provided with a shielding device, so that the chargingport is not easy to leak electricity; the phenomenon that the charging pile is plugged into a socket by hand is avoided, and the safety of the charging pile used at night is effectively improved; thetemperature in the charging pile shell is reduced, and the burning phenomenon of electric appliances in the charging pile shell is effectively prevented; the drying efficiency in the charging pile shell is improved, and the short circuit phenomenon of electric appliances in the charging pile shell is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a protection device for safe charging of electric 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, and cost data printing.

[0003] Although the charging piles in the prior art are practical, they lack protection devices

For example: when the car is in the warehouse, the driver can easily break the body of the charging pile, which will cause irreparable damage to the charging pile; the charging port of the charging pile is not equipped with a sealing device, so the charging port is easy to age and has a short service life. ;When the charging pile is used in rainy days, there is no blocking device for the charging port, so the charging port is prone to leakage; when the charging pile is used in the dark, due to the unclear line of sight, the user is prone to hand plugging into the electric socket, which poses a safety hazard; In the hot summer, the internal temperature of the pile is prone to overheating, and the internal electrical appliances are prone to burnout; in the humid season, the interior of the charging pile is prone to water accumulation, and the internal electrical appliances are prone to short circuit.
