Battery Module Mounting Tray With Integrated Vibration Damping Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery module mounting trays fail to effectively dampen impacts and vibrations during transportation and assembly, and have challenges with weldability and screw alignment.
Innovation Solution
A battery module mounting tray design featuring a bracket with a first support unit forming an inclined 'U'-like shape, a second support unit with a guide unit for automatic screw alignment, and a third support unit with a U-shaped cross-sectional shape for improved weldability, all contributing to enhanced structural support and assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bracket is added to fix the battery module, then vibration resistance is improved, but device complexity increases
Solution Approach 1:
The bracket is integrated with the tray body to form a unified structure, combining the support function of the tray with the fixing function of the bracket. This merging reduces the number of separate components while maintaining vibration resistance, thereby improving reliability without proportionally increasing device complexity.
Solution Approach 2:
The bracket is divided into multiple support units (first support unit, second support unit, third support unit) that can be independently formed or positioned. This segmentation allows each unit to perform specific fixing functions at different locations, effectively dampening vibrations through distributed support points while keeping the overall structure manageable.
2Strength
If the bracket thickness is increased for better structural strength, then strength is improved, but weldability to bottom plate deteriorates
Solution Approach 1:
The bracket employs different thickness specifications at different locations: thicker sections (first and second support units) where structural strength is critical for vibration resistance, and thinner sections (third support unit) where weldability to the bottom plate is prioritized. This local differentiation optimizes both strength and ease of manufacture without compromising either property.
3Manufacturing precision
If a guide unit is added to align screw holes, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The guide unit is pre-formed as an integral part of the bracket structure, creating alignment guides for screw holes before the actual assembly process. This preliminary action ensures that screw holes are automatically aligned during installation, improving manufacturing precision without requiring additional alignment tools or complex adjustment procedures, thereby limiting the increase in device complexity.
