Battery Module Wedge Bracket Fixing for Vibration Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for fixing battery modules in battery packs face challenges in maintaining stability due to low fixing force, especially against vibrations and impacts, as the thickness of the fixing components is small and the methods struggle to provide adequate dimensional safety and stability.
Innovation Solution
The solution involves processing the surfaces of the fixing member, such as the bracket and tray, to increase the frictional force by forming wedge-shaped surfaces, which enhances the fixing force and prevents slippage, allowing for stable fixation against vibrations and impacts in all directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a bolt is used to fix the battery module directly to the tray, then the fixing method is simple, but the fixing force is insufficient due to small thickness of the fixing part
Solution Approach 1:
A wedge-shaped fixing member is introduced as an intermediary component between the battery module and the tray. This fixing member has a wedge shape with an inclined surface that, when pressed against the battery module, generates a reaction force to securely fix the battery module to the tray, thereby increasing the fixing force without significantly increasing device complexity.
2Device complexity
If a conventional bracket is used to fix the battery module, then the structure is simple, but the fixing force against vibration and impact is insufficient
Solution Approach 1:
The fixing member is designed with a wedge shape, changing the geometric parameters of the fixing structure. When the wedge-shaped fixing member is pressed against the battery module, it generates a reaction force through its inclined surface, significantly increasing the fixing force and improving reliability against vibration and impact while maintaining structural simplicity.
3Force
If the thickness of the fixing component is increased to improve fixing force, then the fixing force increases, but the device size and weight increase
Solution Approach 1:
Instead of increasing the thickness of the fixing component, the invention changes the geometric shape to a wedge form. The wedge-shaped fixing member generates fixing force through its inclined surface and reaction force mechanism, achieving high fixing force with minimal material usage, thereby avoiding increased device weight while maintaining strong fixation.
