AI Technical Summary
The existing technology requires disassembling the battery box for battery pack repair, which makes the repair process less convenient.
A first opening is provided on the battery box, through which damaged parts in the control assembly can be quickly repaired, and the internal space can be sealed off when not needed by a sealing element. The projection of the fixing element and the control assembly falls into the opening for easy disassembly.
This improves the ease of maintenance of the battery box, reduces interference from disassembling other components, and enhances maintenance efficiency.
