Battery Module Installation Structure with Side Frame Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery module installation structures for vehicles are complex and inefficient in terms of space usage, and they fail to effectively protect the battery from external impacts and heat management.
Innovation Solution
A battery module installation structure comprising a pair of side frames fixed to the vehicle, a case body between them, and a mounting member that disperses external impacts and allows for efficient space utilization by housing the battery module under the floor or seat, using extruded materials for impact absorption and hollow sections for cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery module is covered by an upper holder and a lower holder that is fixed to a tray, then the battery module is protected, but the mounting structure becomes complicated and requires a large space
Solution Approach 1:
The patent combines the protection function and mounting function into a single integrated structure. The side frames are directly fixed to the vehicle body and simultaneously provide protection and mounting capabilities, eliminating the need for separate upper holder, lower holder, and tray components. This merging of functions reduces structural complexity while maintaining protection reliability.
2Quantity of substance
If the capacity of a battery module is increased, then the running distance is extended, but the installation space efficiency decreases and protection from external impact becomes more difficult
Solution Approach 1:
The patent divides the battery system into modular battery packs that can be independently installed between the side frames. This segmentation allows for flexible arrangement of high-capacity battery modules without requiring a completely complex installation structure, as each module can be independently mounted and protected by the side frame structure.
3Reliability
If many components are used to protect the battery module, then the protection effectiveness is improved, but the space required for installation increases
Solution Approach 1:
The side frames serve multiple functions simultaneously: they provide structural support, protect against external impacts, and serve as mounting structures for the battery modules. This multi-functionality eliminates the need for separate protection components, achieving effective protection while minimizing installation space requirements.

AI summary
Provided is a battery module in-vehicle installation structure, including: a pair of side frames that are fixed to a vehicle and arranged at intervals in a width direction of the vehicle; a case body fastened between the pair of side frames; and a mounting member for mounting the battery module inside the case body. The case body has a floor, side walls standing upright at peripheral edges of the floor, and fastening portions extended respectively from the side walls toward an outer side in the width direction. The mounting member has a pair of fixing portions each extended toward the outer side in the width direction. Each of the pair of fastening portions is fastened so as to be sandwiched between one of the pair of fixing portions and one of the pair of side frames.
