Description

TECHNICAL FIELD

[0001] The utility model relates to charging pile technical field, concretely is a charging pile power assisting mechanism. BACKGROUND

[0002] It is known that the main function of the charging pile is to transmit electric energy into the battery of the electric vehicle to charge it, which provides charging interfaces of different types and power levels to meet the needs of different electric vehicles, and is a device specially used for charging electric vehicles such as electric vehicles and hybrid electric vehicles.

[0003] With the rapid development of the new energy industry, the demand for charging pile facilities is also increasing, and since the charging pile has a large power, the charging gun and charging cable (gun cable) attached thereto are relatively heavy, and it is very laborious to grab the charging gun and drag the gun cable during charging. In view of this situation, a power assisting device is usually used on some charging piles.

[0004] The common power assisting device currently used is usually in the form of a cantilever (as shown in Figure 1 ), or a spring balancer (as shown in Figure 2 ), which assists the heavy charging cable, or uses the charging pile power assisting device and charging pile disclosed in publication No. CN217374196U and the charging pile, power assisting box and charging pile device disclosed in publication No. CN215621470U to assist the heavy charging cable.

[0005] No matter which power assisting device is used, the cable connected to the charging pile needs to be suspended, and the charging gun of the cable naturally droops after being suspended, which is inconsistent with the position required by the actual charging. When charging, the user must manually bend the charging gun upwards to adjust it to the appropriate insertion position (different for different vehicle models). Since the cable of the charging pile is usually thick and lacks flexibility, a large resistance needs to be overcome when manually bending it, which is particularly difficult for users with less strength, especially female users. Especially in winter, it may not be possible to complete the charging process smoothly due to the difficulty in bending the cable, greatly affecting the user's experience and reducing the convenience of using the charging pile.
