Battery Support Frame Layout for Wider Vehicle Battery Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery support frame structures face challenges in increasing the volume of batteries due to the need for elastic members and displacement spaces when batteries are divided between side members, limiting their capacity.
Innovation Solution
A battery support frame structure with side members having holes in the vehicle width direction and a battery inserted through these holes, allowing the battery to span the width without division, and additional members for support and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the battery is divided into inside and outside the side members, then the battery can be installed in the frame structure, but the volume of the battery cannot be increased due to the need for elastic members and displacement spaces
Solution Approach 1:
The frame structure is segmented into multiple side members with through-holes, allowing the battery to be divided and passed through these holes. This segmentation enables the battery to span across side members without requiring elastic members or displacement spaces, thereby increasing battery volume while maintaining structural integrity
Solution Approach 2:
The battery is configured to extend in the vehicle width direction through the through-holes of side members, utilizing the width dimension to accommodate the battery length. This dimensional approach allows the battery to pass through the frame structure without being constrained by the side member spacing in the front-rear direction
2Volume of moving object
If elastic members and displacement spaces are provided for each battery, then stress on the battery is suppressed, but the battery volume cannot be increased
Solution Approach 1:
Multiple side members are merged into a single integrated frame structure with through-holes, allowing the battery to pass through continuously. This merging eliminates the need for separate elastic members and displacement spaces at each side member location, reducing overall structure complexity while maintaining battery protection
Solution Approach 2:
The through-holes in the side members serve as intermediaries that allow the battery to pass through the frame structure. This intermediary structure enables the battery to maintain its volume without requiring additional elastic members or displacement spaces, as the through-holes provide the necessary passage while the frame structure itself provides support

AI summary
A battery support frame structure S has: a plurality of side members 1 extending in the longitudinal direction of a vehicle and having a hole 11 that passes therebetween and is formed in the vehicle width direction; and a battery 2 that is inserted into the hole 11 of the plurality of side members 1 and is longer in the vehicle width direction than the length between the plurality of side members 1. Additionally, the side members 1 extend in a straight line in the vehicle longitudinal direction. The battery support frame structure S additionally has a first member 3 that extends along the battery 2 above the battery 2 in the vehicle height direction, and a second member 4 that extends along the battery 2 below the battery 2 in the vehicle height direction.
