Description

Technical Field:

[0001] The utility model relates to the technical field of charging piles, in particular to a charging pile with an automatically retractable charging gun. Background Art:

[0002] An electric vehicle charging pile is a power station for electric vehicles, and its function is similar to that of a fuel dispenser in a gas station. Each charging pile is equipped with a charging plug, and the charging pile can charge various models of electric vehicles according to different voltage levels. The electric vehicle charging pile adopts AC and DC power supply methods and requires a special charging card for use. The display screen of the charging pile can display data such as the charging amount, cost, and charging time. The cost of the charging pile is relatively high, and the price of a general charging pile is tens of thousands or even more than one hundred thousand. It is mainly installed in parking lots. For some large-power vehicle charging piles in existing charging piles, the charging cable connected after inserting the charging gun is relatively long, has a relatively thick wire diameter and a large weight. Most drivers do not hang up the charging cable after charging, and it is also difficult for some drivers with insufficient strength to hang up the charging cable, thus forming a habit of not hanging up the charging cable. However, the charging cable and the charging gun placed naked on the ground are not only easily damaged, resulting in the charging pile being unable to be used normally, but also pose a danger to pedestrians and vehicle safety, causing accidents. There is an urgent need for a charging pile with an automatically retractable charging gun. Summary of the Invention:

[0003] The purpose of the utility model is to provide a charging pile with an automatically retractable charging gun for the deficiencies existing in the prior art, and the charging gun can automatically retract along with the use of the charging cable.

[0005] For further improvement of the above solution, a charging gun placement seat is arranged on the charging outlet.

[0006] A further improvement to the above solution is that an insertion gun locking mechanism for locking the charging insertion gun is provided on the charging pile body. The insertion gun locking mechanism includes a first electromagnetic switch disposed on one side of the charging gun outlet inside the charging pile body. When the charging insertion gun is not in use, the first electromagnetic switch remains energized and attracts the charging insertion gun; when the charging insertion gun is in use, the first electromagnetic switch remains de-energized and releases the charging insertion gun.

[0007] A further improvement to the above solution is that the winding mechanism further includes a second electromagnetic switch and a limiting hole provided on the upper end face of the charging wire winding wheel. The second electromagnetic switch is disposed at a position close to the end face on one side of the charging wire winding wheel, and the second electromagnetic switch is inserted and matched with the limiting hole.

[0008] A further improvement to the above solution is that a wire pressing wheel is provided at the end of the charging wire winding wheel.

[0009] A further improvement to the above solution is that a charging wire guiding wheel is rotatably provided inside the charging pile body.
