Problems solved by technology

[0002] With the continuous development of new energy technology, a large number of new energy buses have been put into operation in various cities. However, electric buses have the following disadvantages: First, the cost of electric buses is relatively high, the main reason is that electric buses The price of the battery of the car is relatively high; secondly, the capacity of the existing battery is small, so that the battery life of the car is not high. Generally, the method of adding battery packs is used to improve the battery life, but this method will increase the load of the car, and there are Contrary to the goals of lightweight vehicles and energy saving and emission reduction; third, the charging facilities for electric buses are not perfect, the number of existing charging piles is limited, and the charging efficiency is relatively low, which is not conducive to the use and distribution of a large number of electric buses
[0003] Most of the existing bus charging connectors are located on the side of the bus. When the charging connector is located on the roof of the bus platform, the charging connector needs to be installed on the top of the bus. If it is exposed to the air, it is easily damaged by harsh natural environments such as rain and snow.
At the same time, when the bus charging connector is located on the top of the bus, it is difficult to realize the docking of the manual operation of the bus charging connector and the charging interface on the bus platform
