Battery Pack Packaging Structure With Groove Support for Safe Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wooden boxes used for battery pack packaging result in uneven surfaces, making proper placement and stacking difficult, and increase the risk of collisions during transportation, leading to potential accidents such as battery leakage, spontaneous combustion, and explosion.
Innovation Solution
A packaging structure comprising a tray structure with a support portion forming a groove and a cover body, where the battery pack is accommodated in a cavity, with buffer members and packing belts to secure and protect the battery pack, ensuring a flat surface for easy stacking and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional wooden boxes are used for battery pack packaging, then the structure is simple to manufacture, but the surface is uneven making proper placement and stacking difficult
Solution Approach 1:
The packaging structure is divided into modular components: a tray body with support portions forming grooves, a cover body with a cavity, buffer members, and packing belts. This segmentation allows each component to have a specific function while maintaining overall manufacturing simplicity and operational ease through standardized assembly
Solution Approach 2:
The support portions are strategically positioned at specific locations on the tray body to form grooves that provide localized support and create a flat external surface. This local structural enhancement solves the uneven surface problem without requiring complete redesign of the entire packaging structure
2Device complexity
If traditional wooden boxes are used for battery pack packaging, then the structure is simple, but collisions during transportation can easily occur causing safety accidents
Solution Approach 1:
Buffer members are pre-installed at critical positions within the packaging structure to provide cushioning protection before any collision occurs. These buffer members absorb impact forces during transportation, preventing direct contact between battery packs and the packaging structure or ground, thereby avoiding safety accidents while maintaining a relatively simple overall structure
Solution Approach 2:
The groove structure formed by support portions preliminarily restricts the position of battery packs, preventing them from shifting during transportation. This preliminary positioning action counteracts the potential harmful effect of battery pack movement that could lead to collisions
3Reliability
If buffer members and packing belts are added to secure the battery pack, then transportation safety is improved, but manufacturing complexity increases
Solution Approach 1:
Multiple protective functions are merged into an integrated packaging structure: the tray body with grooves provides positioning, buffer members provide cushioning, and packing belts provide restraint. This merging of functions into a unified system achieves high transportation safety while avoiding the complexity of separate, independent protective systems

AI summary
A package structure for a battery pack is provided. The package structure for the battery pack includes a tray structure and a cover body, the tray structure includes a tray body and a support portion. At least a part of the support portion protrudes from a periphery of the tray body in a planar extension direction of the tray body. The support portion cooperates with the tray body to form a groove located at the periphery of the tray body. The cover body is arranged on a first side of the tray body. A cavity is formed on a side, facing the tray body, of the cover body. The battery pack is located on the first side of the tray body and is accommodated in the cavity. At least a part of the cover body is lapped with the groove, and the tray body is accommodated in the cavity.
