Battery Box Reinforcement Layout for Impact Resistance and Space Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery boxes face issues with low space utilization and safety risks due to reinforcement beams occupying internal space and not adequately protecting side walls from impacts, leading to potential wear and tear.
Innovation Solution
A battery box design featuring a reinforcement module with beams fixedly connected to side beams, arranged between cell groups, enhancing structural strength while optimizing space utilization and dispersing impact forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforcement beams are provided in the middle of the box body to improve side anti-collision ability, then the impact resistance and mechanical performance are improved, but the internal space is occupied and space utilization is reduced
Solution Approach 1:
The patent transitions from traditional longitudinal reinforcement beams to transverse reinforcement beams that extend between side walls, changing the orientation and dimension of reinforcement. This allows the reinforcement structure to be integrated with the side wall assembly rather than occupying central internal space, thus improving impact resistance while preserving battery cell arrangement space.
Solution Approach 2:
The reinforcement beam is merged with the side wall assembly to form an integrated structure. The side wall assembly includes the side wall panel and the reinforcement beam as a unified component, eliminating the need for separate internal reinforcement elements that would occupy additional space.
2Strength
If reinforcement beams are provided in the middle of the box body, then the mechanical performance is improved, but the side walls far from reinforcement beams still have risk of wear and tear under external impact
Solution Approach 1:
The box body is divided into multiple reinforcement zones by providing plurality of reinforcement beams that extend between side walls. These beams are positioned at different locations to create segmented reinforcement zones, ensuring that all areas including those far from traditional beam locations are adequately protected against external impact and wear.
Solution Approach 2:
The side wall assembly incorporates reinforcement beams with different configurations tailored to specific locations. The reinforcement beams are designed with appropriate thicknesses, materials, and positioning based on the specific impact risks and mechanical requirements of different regions of the box body.
