Battery Pack Support Member Integrating Mounting Nuts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery packs suffer from reduced space efficiency due to the space between battery modules and support members, which also affects the rigidity and coupling strength of these components.
Innovation Solution
The battery pack design includes a support member with an uneven cross-sectional profile and integrated mounting nuts that allow the battery module to be in direct contact with the support member, eliminating the gap between them and enhancing coupling strength through protrusions and grooves, thereby improving space efficiency and rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support beam with mounting nuts is used to couple battery modules, then the battery module can be securely mounted, but a space gap is formed between the battery module and support beam reducing space efficiency
Solution Approach 1:
The mounting nut is integrated into the support beam to form a unified structure. The mounting nut is formed as an integral part of the support beam through processes like injection molding, eliminating the need for separate mounting nuts and reducing the number of components. This merging eliminates the space gap between the battery module and support beam while maintaining secure coupling through the integrated mounting structure.
2Reliability
If mounting nuts are coupled to support beams with bolts, then battery modules can be secured, but the complex coupling structure reduces rigidity
Solution Approach 1:
The mounting nut and support beam are merged into a single integrated component. This unified structure eliminates the multiple separate parts (support beam, mounting nut, bolt) and their associated coupling interfaces, resulting in a more rigid and stable assembly with fewer potential weak points.
3Ease of manufacture
If space is formed between battery module and support beam for coupling, then mounting is enabled, but the overall volume of the battery pack increases
Solution Approach 1:
The mounting nut is integrated directly into the support beam structure, allowing the battery module to be mounted without requiring additional space between the module and support beam. The integrated design enables the battery module to be positioned flush against the support beam, maximizing space utilization and reducing the overall battery pack volume.
