Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically a wall-mounted charging box structure. Background Technology

[0002] As an component of electronic products, the chassis primarily serves to house and secure various parts, providing support and protection. In the case of charging stations, the chassis mainly houses charging modules and charging guns. Currently, charging station chassis are typically fixed to the ground, occupying a significant amount of floor space. Therefore, to improve space utilization, many wall-mounted charging stations have emerged on the market, effectively addressing this issue.

[0003] However, existing wall-mounted charging pile enclosures require pre-reserved space on the enclosure during installation and are connected to the wall and vertical charging piles via brackets, bolts, and other structures. This complex structure not only makes the installation of wall-mounted charging pile enclosures time-consuming and labor-intensive with low installation efficiency, but also requires the enclosure to be disassembled and taken to a repair shop for maintenance during later inspections. Otherwise, if the charging pile is damaged, professional personnel will need to come to the site for repairs, which undoubtedly increases maintenance costs and is not conducive to later maintenance.
