EV Battery Pack Cross-Brace Structure for Body Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The attachment of a battery pack to electric vehicles often leads to vehicle imbalance due to insufficient rigidity, which affects followability and stability during turns.
Innovation Solution
A vehicle body reinforcing structure with a cross connection design, including reinforcing rods and brackets, is integrated to enhance the structural strength and stability of the vehicle body and battery pack, preventing imbalance and shaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a battery pack is attached to the vehicle body, then the power supply capability is improved, but the vehicle body rigidity deteriorates causing imbalance
Solution Approach 1:
The vehicle body reinforcing structure member is divided into multiple segments: a main body portion that reinforces the vehicle body, and multiple branching portions that connect to the battery pack. This segmentation allows the structure to simultaneously address both the power supply requirement (by connecting to battery) and the rigidity requirement (by reinforcing vehicle body at multiple locations).
Solution Approach 2:
The invention merges the battery pack connection function with the vehicle body reinforcement function into a single integrated structure member. The reinforcing structure member simultaneously serves as both a battery mount and a structural reinforcement element, eliminating the need for separate components and achieving both power supply integration and rigidity enhancement.
2Stability of the object's composition
If the vehicle body rigidity is improved by attaching battery pack, then the stability is improved, but the imbalance occurs due to lack of rigidity distribution
Solution Approach 1:
The reinforcing structure member provides localized reinforcement at specific critical points of the vehicle body through its branching portions. Each branching portion connects to different locations on the vehicle body, providing targeted rigidity enhancement where needed most, rather than uniform reinforcement throughout the entire structure.
Solution Approach 2:
The reinforcing structure member extends in multiple spatial dimensions with branching portions extending in different directions from the main body. This multi-dimensional configuration allows the structure to reinforce the vehicle body at multiple locations simultaneously, creating a distributed rigidity enhancement pattern that improves overall stability without causing imbalance.
