Battery Module Protecting Assembly Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery module protecting assemblies have low protection levels and weak connecting strength, leading to potential failure under vibration.
Innovation Solution
A protecting assembly comprising a base and an upper cover with a receiving cavity, where the limiting wall is inclined to facilitate easy assembly and enhance connecting strength, preventing separation during vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the protecting assembly uses a conventional connection structure, then the assembly process is simple, but the connecting strength between members is low and the protection level is insufficient
Solution Approach 1:
The limiting wall is designed with an inclined curved surface that fits into the groove of the base. This inclined surface allows the upper cover and base to connect through a sliding insertion motion, creating a large contact area that significantly enhances connecting strength while maintaining assembly simplicity.
Solution Approach 2:
The limiting wall of the upper cover is inserted into the groove of the base, creating a nested connection structure. The first side wall of the upper cover laps over the first side plate of the base, forming an overlapping nested arrangement that provides both mechanical strength and structural integration.
2Reliability
If the protecting assembly uses a simple connection structure, then the assembly process is easy, but the assemblying strength is low causing failure under vibration
Solution Approach 1:
The inclined surface of the limiting wall enables a sliding insertion assembly process that is as easy as conventional methods, while simultaneously creating a mechanically interlocked structure with high vibration resistance and reliable protection.
Solution Approach 2:
The connection structure utilizes three-dimensional spatial arrangement where the limiting wall extends in multiple directions, creating a multi-dimensional interlocking mechanism that provides reliable protection without complicating the assembly process.
