Description

Technical Field

[0001] The utility model relates to the technology in the field of AC charging piles, in particular to a wall-mounted intelligent European standard AC charging pile installation structure. Background Art

[0002] A charging pile refers to a charging device that provides energy replenishment for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. 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 operations and print cost data. The charging pile display can display data such as charging capacity, cost, and charging time.

[0003] There are mainly two modes for installing AC charging piles. The first is to install the charging pile directly on the wall. During the installation process, the charging pile is more troublesome to fix due to its certain weight. The second is to install a stand on the base plate and then install the charging pile on the stand. Most of the existing installation structures of charging piles are to set mounting ear plates outside the shell, and the installation of the charging pile is achieved by bolts and mounting ear plates. This type of structure has certain defects in the specific application process. The shell of the charging pile needs to be completely attached to the wall or the stand. If the wall is not flat enough, unstable installation is likely to occur.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
