Problems solved by technology

[0002] New energy vehicles can greatly reduce the fuel consumption during vehicle operation and reduce exhaust emissions. Since the battery must ensure a certain capacity to meet the mileage requirements of the vehicle, and the construction and maintenance costs of charging stations are high, it is currently impossible to achieve large Area coverage, some cities do not even have charging stations, which leads to problems in the charging of electric vehicles, which hinders the development and promotion of electric vehicles, especially for urban electric buses (including pure electric buses, plug-in buses) that need to be charged. Hybrid electric buses, etc.), due to the short operation interval of buses, it is not conducive to long-term charging, so the current charging methods suitable for electric buses are fast charging and night charging, but the routes of general buses are scattered and difficult to concentrate Charging, the traditional charging pile is generally short, and the power-taking terminal of the vehicle is set on the side of the vehicle, mainly for the convenience of manual operation, but such manual operation is dangerous and long-term operation will increase the workload of people, especially It is the charging of electric buses (the electric buses mentioned below include pure electric buses, plug-in hybrid buses and other buses equipped with energy storage power supply and can be charged externally), because the buses need to work for a long time during the day, Moreover, the number of charging stations is also very limited. Therefore, electric buses can only choose to charge at night, but often the bus station is far away from the charging station, and the bus will consume a lot of energy when driving to the charging station and returning to the bus station from the charging station. , and the bus has a long working route and long working hours, which also requires a large number of charging times per day for the bus, but the existing charging stations cannot meet this demand, and there is a certain risk in manually plugging in high-voltage electric guns , due to the above problems, the existing charging method cannot be used as a general charging method, and it is urgent to propose a charging device for automatic charging

[0003] Some existing charging methods use wireless charging, using coil induction to achieve wireless charging, but this charging method requires the driver to park the vehicle at the transmitter of the charging device more accurately, and then charge by magnetic attraction. When the vehicle and the transmitter of the charging device are connected Charging cannot be realized if the distance is too large, so the driver’s parking requirements are high, and all or part of the charging device is on the ground, and when the vehicle (especially a bus) is parked, there will be people up and down, which poses a safety hazard
