Lateral Battery Bracket Structure for Impact Absorption and Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery pack systems are cumbersome to maintain and repair due to their modular structure, which requires dismounting the entire system for replacing defective parts, leading to inefficiencies and increased costs.
Innovation Solution
A lateral battery bracket system comprising an outer and inner structure, where the inner structure meanders between the lower and upper parts of the outer structure, providing contact areas for stabilization and allowing for deformation to absorb external impacts, thereby enhancing the mechanical integration and ease of maintenance of battery packs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the battery pack uses a modular structure with multiple submodules, then the energy content and power output are improved, but the complexity of mechanical integration and maintenance increases
Solution Approach 1:
The battery pack is divided into multiple submodules, each containing a specific number of battery cells connected in series. These submodules are then connected in parallel to achieve the desired power output while maintaining manageable individual units that can be independently handled during assembly and maintenance operations
2Ease of repair
If the entire battery system is disassembled for replacing defective parts, then complete access to all components is achieved, but maintenance time and operational efficiency are reduced
Solution Approach 1:
The battery pack is segmented into independent submodules that can be individually accessed and replaced. When a defective part needs replacement, only the specific submodule containing that part needs to be removed, not the entire battery system. This allows maintenance personnel to quickly locate and replace defective components while leaving the rest of the battery system operational
Solution Approach 2:
The invention extracts the ability to independently remove and replace submodules from the overall battery system. Each submodule is designed with connection points and mounting structures that allow it to be separated from the battery pack without affecting other submodules, enabling selective maintenance of only the defective portion

Function Achieved in This Case
The battery bracket system improves the mechanical integration and ease of maintenance of battery packs by allowing for deformation to absorb external impacts, reducing the burden of replacing defective parts and enhancing the overall efficiency and cost-effectiveness of battery pack systems.
Implementation Method 1
the inner structure meanders between the lower part and the upper part such that the inner structure has one or more lower contact areas where it contacts the lower part and one or more upper contact areas where it contacts the upper part

AI summary
A battery bracket for mounting a battery pack case to a vehicle is provided. The battery bracket includes: an outer structure having a lower part and an upper part forming a cavity therebetween; and an inner structure in the cavity. The outer structure is configured to be fixed to an outer side face of the battery pack case. The inner structure meanders between the lower part and the upper part of the outer structure such that a lower contact area and an upper contact area are formed at where the inner structure contacts the lower part of the outer structure and the upper part of the outer structure, respectively.
