Technical Field

[0001] The present invention relates to the technical field of new energy vehicle charging, and in particular to a new energy vehicle charging connection device and a use method thereof. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source, or use conventional automotive fuels and adopt new on-board power devices, integrating advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. The composition of electric vehicles includes: electric drive and control systems, mechanical systems such as drive force transmission, working devices to complete the given tasks, etc. The electric drive and control system is the core of electric vehicles and the biggest difference from internal combustion engine vehicles. The electric drive and control system consists of a drive motor, a power supply, and a speed regulator for the motor. The most widely used power source is the lead-acid battery, but with the development of electric vehicle technology, lead-acid batteries are gradually being replaced by other batteries due to their low energy, slow charging speed and short life. The power sources being developed mainly include sodium-sulfur batteries, nickel-cadmium batteries, lithium batteries, fuel cells, etc. The application of these new power sources has opened up broad prospects for the development of electric vehicles. Charging piles, also called electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electric energy to electric vehicles, enabling electric vehicles to store enough electricity to support their operation.

[0003] For example, a patent document with announcement number CN 118306247 B discloses a new energy vehicle charging connection device, which belongs to the field of auxiliary power supply technology for new energy vehicles, and includes a concrete base and a charging pile body above the concrete base, a cable box is provided under the charging pile body, a charging cable is provided on the outside of the cable box, a charging gun is provided at the end of the charging cable, a gun head hole for storing the charging gun is provided on the outside of the charging pile body, and a cable length compensation mechanism is also provided in the cable box, and the charging cable realizes length compensation through the cable length compensation mechanism; the new energy vehicle charging connection device can stably support and limit the charging gun, effectively protect the pin structure of the charging gun, and avoid bending or even breaking of the pins. In addition, the length of the charging cable can be compensated according to needs during use, and the compensated cable can also be retracted. The overall structure is stable and easy to operate, which is suitable for popularization and use.

[0004] However, when this structure is used for charging and replenishing new energy vehicles, due to the limitations of its own structure, it is often necessary to manually plug and unplug the charging gun, and it is impossible to achieve a quick adaptation and docking operation between the charging gun and the charging port of the new energy vehicle. In addition, during the overall charging process, the charging gun and the charging interface of the new energy vehicle are exposed to the outside, which are easily affected by the surrounding environment.
