Battery Module Assembly with Integrated Cover Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery module assemblies experience increased volume and lack rigidity, requiring additional fixing devices and compromising safety and production efficiency due to the lack of a comprehensive cover structure to securely fasten and protect terminal parts and cables.
Innovation Solution
A battery module assembly with a base plate, upwardly bent side walls, an upper cover plate with downwardly bent side walls, a plate-shaped assembly cover, and an electrically insulative module cover that securely fastens and protects electrode leads, cables, and terminal parts, preventing release or rotation, while maintaining a compact structure and improving rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixing plates and frames are used to secure battery modules, then the battery modules can be fixed, but the overall volume of the battery module assembly increases
Solution Approach 1:
The patent integrates the fixing function into the base plate itself through integrated fixing protrusions that engage with the battery modules, eliminating the need for separate fixing plates and frames. This merging of functions reduces the overall assembly volume while maintaining reliable fixation of the battery modules.
2Device complexity
If conventional fixing structures are used without a comprehensive cover, then the structure is simpler, but additional fixing devices are required which compromises safety and production efficiency
Solution Approach 1:
The cover plate serves multiple functions simultaneously: it protects terminal parts, secures cables through integrated cable fixing protrusions, and provides structural completion to the assembly. This multi-functional design eliminates the need for additional separate fixing devices while enhancing safety and maintaining production efficiency.
3Device complexity
If the battery module assembly lacks a comprehensive cover structure, then fewer components are needed, but terminal parts and cables cannot be securely fastened and protected
Solution Approach 1:
The cover plate integrates multiple protective and securing functions into a single component: it covers terminal parts for protection, includes cable fixing protrusions to secure cables, and provides structural enclosure. This eliminates the need for multiple separate components while comprehensively protecting terminal parts and cables from external hazards.
