Battery Rack Fixing Frame for Impact-Resistant Module Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery racks with multiple heavy modules are prone to deformation or breakage during delivery due to external impacts, leading to increased delivery costs and assembly requirements.
Innovation Solution
A battery rack design featuring a fixing frame with hook-coupled hanger members and support portions that attach to battery modules, along with a rack case structure enhanced by C-shaped and rectangular pillars for increased mechanical strength, allowing easy assembly and disassembly during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple heavy battery modules are loaded in the rack case, then the battery rack capacity increases, but the rack case is deformed or broken by external impacts during delivery
Solution Approach 1:
The rack case is divided into multiple rack frames that are separately deliverable. Each rack frame can be independently transported and then assembled at the installation location, distributing the structural load and reducing the risk of deformation during delivery while maintaining the capacity to hold multiple heavy battery modules.
Solution Approach 2:
The rack frames are pre-assembled with battery modules at the manufacturing location before delivery. This preliminary assembly allows the structure to be optimized for both transport durability and load-bearing capacity, with the understanding that final assembly or reconfiguration can occur at the installation site if needed.
2Strength
If the rack case and battery modules are separately delivered to prevent deformation, then the rack case durability is improved, but the delivery volume increases and assembly is required at installation location
Solution Approach 1:
The rack frames and battery modules are combined into a pre-assembled unit at the manufacturing location. This merging allows the structure to be optimized for both transport durability and load-bearing capacity, while reducing the assembly complexity at the installation location since the major components are already integrated.
3Strength
If the rack case is reinforced to prevent deformation during delivery, then the rack case durability is improved, but the weight of the rack case increases
Solution Approach 1:
The rack case is segmented into multiple rack frames that can be separately delivered and assembled. This segmentation allows each frame to be optimized for strength-to-weight ratio, using material efficiently in each segment rather than over-reinforcing a single monolithic structure, thereby maintaining durability while controlling overall weight.

AI summary
A battery rack with increased durability to prevent a rack case from being deformed or broken by external impacts during delivery. To achieve the above-described object, the battery rack includes a plurality of battery modules arranged in a first direction, at least one rack case including a plurality of rack frames configured to mount the plurality of battery modules, and at least one fixing frame including a body in the shape of a plate extending along the plurality of battery modules and a fixing portion formed on one surface of the body and configured to be attached and detached to/from each of the plurality of battery modules.
