AI Technical Summary
Existing BDU designs suffer from structural issues such as radial deformation, especially in the design of lightweight and small size, leading to issues like outward deformation and disengagement of clips, affecting product quality and reliability.
An anti-turnover BDU shell structure is designed with an upper and lower shell, a buckle and clamp head, and an anti-turnover piece to prevent outward deformation, featuring a first and second surrounding wall with a protruding anti-turnover member to limit such deformation.
The structure effectively prevents the outward deformation of the upper shell relative to the lower shell, ensuring the stability and reliability of the BDU by preventing buckle disengagement, while maintaining a simple design and low production costs.

[0002] More commonly, a corresponding BDU, or power cut-off unit, is designed inside the battery pack to achieve functions such as charge and discharge control and circuit overload and short circuit protection. Common BDUs on the market generally include a shell, as well as copper busbars, relays, contactors and other functional components integrated into the shell.
[0003] However, due to design limitations, existing BDUs often require that various functional components be installed relatively compactly in the shell. In order to further meet the design requirements of lightweight and small size, the shell often adopts a two-part shell structure with upper and lower parts, and the upper and lower parts are connected and fixed by corresponding clips. During installation, use, storage and stacking, the upper shell is often prone to radial deformation, especially the clips connected to the upper shell are prone to outward deformation and disengagement, which greatly affects the quality of the product.
