Description

Technical Field

[0001] This invention relates to the field of charging pile protection technology, specifically to a charging pile gun wire protection device and protection method. Background Technology

[0002] Multi-level parking garages are a major means of solving urban parking problems. In recent years, the number of new energy vehicles has increased rapidly, and multi-level parking garages with charging functions have gradually become more common. To facilitate parking on the upper level of a multi-level parking garage, at least one lateral parking space is set on the first level. A vehicle carrying tray is set on the lateral parking space. When a vehicle is parked or retrieved on the upper or lower level, the vehicle carrying tray needs to move frequently left and right to avoid the parking space directly above or below moving to the first level.

[0003] This necessitates frequent left-right movement of the charging gun by the vehicle carrier tray located on the first floor. When the vehicle carrier tray is far from the charging pile, the charging gun travels a long distance, causing the charging gun cable to drag on the ground frequently, resulting in friction and making it prone to damage and leakage. This increases both usage costs and safety hazards. Furthermore, even with a protective shell around the charging gun cable, it is still prone to bending during dragging. Over time, this further increases damage to the internal cables, reduces the overall lifespan, increases maintenance costs, and fails to meet the requirements for safe and reliable charging.
