Battery Mounting Structure for Side-Impact Energy Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery mounting structures face inefficiencies in energy absorption due to rotational deformation of the energy absorption portion and increased mass and manufacturing costs when the energy absorption and battery cross portions are displaced, necessitating a simpler and more effective design.
Innovation Solution
A battery mounting structure with a vehicle frame having a hollow structure, battery modules arranged along multiple directions, a battery cross portion, and an energy absorption portion outside the frame, supported by overlapping first and second portions that coincide with the battery cross portion to enhance energy absorption efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the energy absorption portion and battery cross portion are displaced in the width direction, then the energy absorption portion can be positioned independently, but the energy absorption portion undergoes rotational deformation reducing absorption efficiency
Solution Approach 1:
The patent introduces a first portion as an intermediary component positioned between the battery cross portion and the vehicle frame. This intermediary element provides a connection interface that allows the energy absorption portion to be positioned independently while preventing rotational deformation, thus maintaining energy absorption efficiency despite positional displacement.
2Adaptability or versatility
If the energy absorption portion is disposed outside the skeleton portion, then the skeleton portion can support the load, but the distance between support points increases requiring greater bending strength and mass
Solution Approach 1:
The patent segments the support structure into distinct functional components: the battery cross portion for primary support, the first portion for connection and load distribution, and the energy absorption portion for collision energy management. This segmentation allows the skeleton portion to maintain structural flexibility while reducing its mass, as the support function is distributed across multiple specialized components rather than requiring the skeleton to bear all loads independently.

AI summary
A battery mounting structure includes: a vehicle frame having a hollow structure extending along a front-rear direction of a vehicle on both sides of the vehicle; a plurality of battery modules arranged inside the vehicle frame and arranged along the front-rear direction and a width direction orthogonal to the front-rear direction; a battery cross portion extending along the width direction in the vehicle frame; an energy absorption portion arranged outside the vehicle frame in the width direction, the energy absorption portion being configured to absorb energy of a collision on a side of the vehicle; and a first portion arranged between the battery cross portion and the vehicle frame to at least partially overlap both of the battery cross portion and the energy absorption portion when projected in the width direction.
