Segmented Battery Mounting Structure for Electric Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery mounting structures for electric vehicles increase weight and cost due to their design, and they lack effective crash-resistant capabilities.
Innovation Solution
A battery mounting structure comprising a pair of longitudinal body members, a transverse body member, a battery case made of polybutylene resin with glass fibers, and supporting members made of iron, which securely holds the battery and includes crash-proof blocks to prevent movement during collisions, maintaining a gap between the battery case and other vehicle components to avoid damage.

Engineering Contradiction Analysis
1Reliability
If a battery mounting frame in a grille shape is used to fix the battery, then the battery is securely mounted, but the weight and cost of the electric vehicle increase
Solution Approach 1:
The battery mounting structure is divided into multiple independent supporting members (first supporting members 61A-61D and second supporting members 62A-62B) instead of using a single integrated grille-shaped frame. Each supporting member is a separate component that connects the battery case to specific body members, providing secure mounting while reducing overall material usage and weight.
Solution Approach 2:
The invention extracts and removes the unnecessary grille-shaped frame structure from the mounting system. By taking out this heavy frame and replacing it with minimal supporting members positioned only where structural connection is needed, the design achieves crash resistance without the excess weight of a complete grille framework.
2Reliability
If a battery mounting frame in a grille shape is used to fix the battery, then the battery is securely mounted, but the cost of the electric vehicle increases
Solution Approach 1:
The mounting structure is segmented into multiple simple supporting members rather than a complex integrated frame. This segmentation allows for easier manufacturing of individual components and simplifies assembly processes, reducing overall production cost while maintaining the necessary crash-resistant functionality.
Solution Approach 2:
By removing the expensive grille-shaped frame and retaining only the essential supporting members needed for crash resistance, the invention reduces material costs and manufacturing complexity, thereby lowering the overall vehicle cost while preserving reliability.
3Reliability
If supporting members connect between body members and battery case, then crash resistance is improved, but device complexity increases
Solution Approach 1:
The mounting structure is segmented into discrete supporting members positioned at specific locations rather than a continuous complex frame. This segmentation simplifies the overall design by breaking down the crash-resistant function into multiple simple, localized connections between body members and the battery case.

AI summary
A structure for mounting a battery onto an electric vehicle comprises: a pair of first body members extending in a longitudinal direction of the electric vehicle; a second body member, which connects the pair of first body members, extending in transversal direction of the electric vehicle; a battery case, which contains a battery, disposed between the pair of first body members and rear of the second body member; a plurality of first supporting members, which connect between the pair of first body members, fixed on a bottom of the battery case; and a second supporting member connecting between one of the first supporting members, which is disposed in the forefront of the battery case.
