Battery Box End-Wall Mounting for Higher Cell Packing Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of improving pack assembly efficiency in batteries is hindered by the space occupied by mounting structures extending to the side direction of the box body, limiting the internal space available for battery cells.
Innovation Solution
The mounting structure is arranged on the end wall of the box, overlapping with it in the thickness direction, reducing the side extension and allowing the side space to accommodate more battery cells, with features like mounting holes, embedded members, and partition beams enhancing stability and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the mounting structure extends to the side direction of the box body, then the connection between the box and device is stable, but the internal space available for battery cells is reduced
Solution Approach 1:
The mounting structure transitions from a side-direction extension to an end-wall integration, utilizing the thickness direction of the end wall to accommodate the mounting structure. This dimensional repositioning allows the mounting structure to overlap with the end wall in the thickness direction, freeing up side space for battery cells while maintaining connection stability through the integrated end-wall design
2Productivity
If the mounting structure is integrated into the end wall, then the pack assembly efficiency is improved, but the structural strength of the end wall may be compromised
Solution Approach 1:
The mounting structure is merged with the end wall through overlapping integration in the thickness direction. This combining approach allows the mounting structure to become part of the end wall assembly, improving pack assembly efficiency by eliminating separate mounting components while the overlapping design distributes structural loads to maintain end wall strength

AI summary
A box includes a box body and a mounting structure. The box body is provided with an opening and an end wall arranged oppositely. The mounting structure is arranged on the end wall, and when viewed in the thickness direction of the end wall, the mounting structure overlaps with the end wall, and the mounting structure is configured to connect the box body and a device. The mounting structure is arranged on the end wall of the box, which can reduce the size of the part of the mounting structure extending to a side direction of the box body or prevent the mounting structure from extending to the side direction of the box body, thereby reducing the external space occupied by the mounting structure along the side direction of the box body or avoiding the mounting structure occupying the external space along the side direction of the box body.
