Technical Field

[0001] The utility model relates to the technical field of charging piles, and in particular to a sheet metal part with self-adaptive assembly tolerance. Background Art

[0002] Charging piles refer to charging equipment that provides charging services for electric vehicles. Charging piles are mainly divided into floor-standing charging piles and wall-mounted charging piles. Charging piles can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels.

[0003] Generally, a charging pile includes a shell structure, and then the circuit part is installed inside the shell. When processing the shell, multiple pairs of plates are processed using sheet metal technology to achieve rapid prototyping of the shell components, and finally the formed components are assembled to achieve the manufacturing of the charging pile shell. Due to the assembly errors between the components, sometimes the components processed by a single sheet metal cannot be well matched later, resulting in many plates needing to be scrapped, resulting in a waste of metal resources and reducing the production efficiency of the charging pile. Therefore, it is urgent to design a sheet metal part with adaptive assembly tolerance to solve the above problems. Utility Model Content
