Description

Automatic rapid charging device for electric vehicles

The present invention provides a charging gun to the position of a charging port of an electric vehicle by inserting and withdrawing a charging cable that can be rotated by a direction changing means and a direction changing means through which the charging cable is mounted. It relates to a fully automatic super fast charging device for an electric vehicle that can increase the convenience of use by ensuring the transport and handling.

In general, the charging cable used in the charging device for an electric vehicle has a heavy weight and is inflexible, so when moving to the charging location of the electric vehicle, the charging cable is warped and the charging gun is matched to the direction and height of the charging vehicle. It is not easy to insert into the filling port.

Accordingly, there is a problem that charging is difficult because the handling of the charging cable is not easy in the case of the disabled, the elderly, and women as well as the general public. In addition, the charging cable is difficult to handle because it uses a cable with high voltage and high current, and the heavy weight may cause the layered cable and the charging gun to hit the floor, to fall off, and to be worn or damaged, thereby preventing the user's body from the risk of electric shock. Development of charging guns for protection has been required.

In addition, in the case of the rapid charging device, the weight of the charging cable is heavier, so the problem as described above is more serious.

That is, in the existing charging device, the charging cable has a heavy weight, and thus, if the length of the charging cable is long, there is a fear of falling from the mounting position to the floor. If it falls on the bottom of the charging cable in this way, it may be worn or damaged due to friction with the floor. If the charging cable is damaged, there is a risk of electric shock, which can be a safety problem.

In addition, according to the location of the charging socket of the electric vehicle in the existing charging device, the user must handle the charging cable directly, such as carrying the charging cable.
