New energy automobile charging device with protection function

Abstract

The invention discloses a new energy automobile charging device with a protection function. The device comprises a pile body, an electricity connection cavity, a first transmission cavity, a second transmission cavity, a third transmission cavity and a wire retraction cavity are formed in the pile body, an operation cavity and a sealing cavity with the openings facing right are formed in the rightend surface of the pile body, and a charging gun placing cavity is communicated with the left end of the sealing cavity; a sliding block capable of transversely sliding is arranged in the electricityconnection cavity, an upper power supply block and a lower power supply block are arranged on the right end wall of the electricity connection cavity, and an upper electricity connection hole matchedwith the upper power supply block and a lower electricity connection hole matched with the lower power supply block are formed in the right end surface of the sliding block. The device is simple in structure, wire retraction and release work of a charging wire can be well achieved, the problem that the charging wire is exposed outside the charging device and damaged is avoided, and closing and opening of the charging gun placing cavity can be selectively controlled through an operation hand wheel; operation is easy and convenient, the safety is high, and the risk of an electric shock in the operation process is greatly reduced.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a charging device for a new energy vehicle with a protection function. Background technique [0002] In recent years, the problem of urban environmental pollution has become more and more serious, among which automobile exhaust pollution is increasingly endangering people's health. With the improvement of environmental protection awareness, the rapid development of low-carbon economy and energy-saving emission reduction technology, electric vehicles have The advantages of pollution have begun to be popularized and applied in daily life. [0003] The charging device is an important basic supporting charging facility for electric vehicles. The use process of the charging device is very similar to the refueling process of the car.

Problems solved by technology

[0003] The charging device is an important basic supporting charging facility for electric vehicles. The use process of the charging device is very similar to the refueling process of the car. During the charging operation of the electric vehicle, the operator needs to remove the charging gun from the charging device and connect it with the charging device of the electric vehicle. Hole connection, after the charging is finished, the operator should arrange the charging wires, and then put the charging gun head back into the charging device, but the charging wire has a certain length, which brings great inconvenience to the user when it is put back. In addition, If the charging wire is not retracted and exposed to the outside of the charging device, when the charging device is not in use, the charging wire is placed next to the charging device. When the charging wire is scattered in an improper position, there is a risk of the charging wire being trampled by people or being run over by a car. As a result, the outer insulation of the charging wire will be damaged, resulting in a decrease in the service life of the charging wire and poor safety protection; in addition, when the traditional charging gun is placed on the charging device, it is always in a power-on state, and there is no protection device for the charging gun. If children or other non-operators take it at will, it will cause electric shock and other accidents.
