Description

TECHNICAL FIELD

[0002] The new energy charging pile is a device for providing electric energy for electric vehicles, which can be fixed on the ground or wall, installed in public buildings and residential parking lots or charging stations, and can charge various types of electric vehicles according to different voltage levels. The input end of the new energy charging pile is directly connected with the AC power grid, and the output end is provided with a charging plug for charging electric vehicles. The new energy charging pile is widely used and has important significance for promoting green transportation and reducing environmental pollution. With the popularization of new energy vehicles, the construction and development of charging piles have become an indispensable part of the new energy vehicle industry.

[0003] The charging pile mainly consists of a charging pile box, a charging gun and a charging cable for charging piles. The charging gun and the connected cable are exposed to the outside for a long time, and the cable is prone to winding and damage. The existing Chinese patent document CN114683898B discloses a new energy vehicle charging pile. By changing the positions of the supporting pulley and the two supporting vertical plates, the charging cable can always be kept tight on the outside of the supporting pulley when it is stretched and elongated, and the charging cable can always be kept in a tight state on the outside of the supporting pulley during the process and will be recovered. The charging cable can be neatly and orderly stored, and the cable will not be wound during use and storage. Although the cable can be well stored, the surface of the cable is made of rubber material, but the cable in a long-term tight state will cause certain tension, which can easily cause cracks or breakage on the surface of the cable. If the cable is pulled, the cable will also be in a state of tension, and improper force will easily cause the elastic extension of the surface of the cable, which can easily cause the breakage of the outer skin of the cable.

[0025] Example two: please refer to Figure 3 、 Figure 7 and Figure 8The embodiment further illustrates the first embodiment. The wire mechanism in the drawing includes an arc-shaped plate 21 arranged above the charging plug 5, which facilitates contact with the top of the charging plug 5. The inner side of the arc-shaped plate 21 is fixedly installed with an arc-shaped strip 22. The end of the charging plug 5 close to the cable 4 is fixedly installed with a mounting ring 23, and the outer diameter of the mounting ring 23 is smaller than that of the charging plug 5. The side of the arc-shaped strip 22 away from the arc-shaped plate 21 is close to the outer side of the mounting ring 23, so that the arc-shaped strip 22 provides a limit for the recovery of the charging plug 5. The outer side of the arc-shaped strip 22 is in contact with the outer side of the charging plug 5. The two ends of the arc-shaped plate 21 are fixedly installed with a fixed rod 24. The end of the fixed rod 24 away from the arc-shaped plate 21 is fixedly installed with a support plate 25. The end of the support plate 25 away from the fixed rod 24 is rotatably installed on the outer side of the adjacent U-shaped frame 7.

[0026] In the embodiment, when the cable 4 is recovered, the resilience of the arc-shaped spring 29 can pull the sliding block 28 to move along the arc-shaped cavity of the U-shaped frame 7, so that the sliding block 28 pulls the support plate 25 and the fixed rod 24 to swing downward through the arc-shaped rod 27. The fixed rod 24 pulls the arc-shaped strip 22 on the arc-shaped plate 21 to be attached to the outer side of the cable 4, so that the cable 4 can be recovered along the inner side of the take-up box 9, preventing the cable 4 from being wound.

The outer side of the concave pulley 33 is in contact with the outer side of the cable 4 to provide support for the bottom of the cable 4, facilitating pulling out and retracting of the cable 4.

[0030] In the embodiment, when the cable 4 is retracted, the cable 4 can move along the outer side of the slide ball 31 to improve the smoothness of the cable 4. The arc-shaped strip 22 with a rubber structure can provide a buffer for the collision between the mounting ring 23 and the arc-shaped strip 22 when they are in contact. When the cable 4 is pulled out and retracted, it can move along the concave pulley 33 outside the roller shaft 32 to improve the convenience of pulling out the cable 4.
