Battery Pack Temperature Adjustment Mechanism Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems in vehicles are vulnerable to damage from impacts, particularly when a cooling mechanism is mounted on the bottom surface, leading to potential damage to both the battery and the temperature adjustment mechanism.
Innovation Solution
A battery pack design with a temperature adjustment mechanism integrated into the battery cover, featuring gaps between the battery and the battery case bottom surface or between an under guard and the battery case bottom surface, which helps absorb impacts and protects the battery and temperature adjustment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the cooling mechanism is mounted on the bottom surface of the battery case, then the temperature adjustment function is improved, but the battery and cooling mechanism become vulnerable to impact damage
Solution Approach 1:
The temperature adjustment mechanism is relocated from the bottom surface (vertical dimension) to the battery cover (horizontal dimension), changing the spatial arrangement to avoid direct exposure to bottom-side impacts while maintaining cooling functionality through the battery case walls
Solution Approach 2:
A cushioning member is provided between the battery and the bottom surface of the battery case to absorb impact energy before it reaches the battery, protecting both the battery and the temperature adjustment mechanism from damage
2Volume of moving object
If the battery is closely fitted in the battery case, then the space utilization is improved, but the battery becomes vulnerable to impact damage
Solution Approach 1:
A cushioning member is introduced between the battery and the battery case bottom surface to provide impact absorption, allowing the battery to be securely mounted while protecting it from impact damage during vehicle operation

AI summary
A moving body includes a floor panel, and a battery pack disposed below the floor panel. The battery pack includes a battery, a battery case having an opening on an upper side and accommodating the battery, a battery cover covering the opening of the battery case, and a temperature adjustment mechanism provided in the battery cover. A gap is provided at least either between the battery and a bottom surface of the battery case or between an under guard provided below the bottom surface of the battery case and the bottom surface of the battery case.
