Battery Rack Fixing Groove for Precise Heavy-Rack Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of accurately positioning and installing heavy battery racks in medium and large devices, such as vehicles and energy storage systems, is exacerbated by the difficulty in precise adjustment during transportation, leading to uneven arrangements and potential issues with electrical connections and firefighting facilities.
Innovation Solution
A battery rack design featuring a rack case with a fixer unit that includes a fixing groove, a shelf frame, and a frame with pillar portions, allowing for stable fixation through bolt-fastening, guided by a guide unit, and enhanced by an elastic member and restraining bar for easy installation and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If transportation equipment is used to move heavy load battery racks, then the battery rack can be transported to the installation site, but it becomes difficult to precisely adjust the position of the battery rack
Solution Approach 1:
The patent applies preliminary action by pre-designing the fixing groove structure in advance. The fixing groove is formed in advance on the battery rack case, allowing for easy and precise positioning when the rack is installed. This pre-prepared structural feature eliminates the need for complex on-site adjustments while maintaining high positioning accuracy despite the heavy weight of the battery rack.
2Quantity of substance
If the battery rack is designed with heavy load capacity, then it can accommodate more battery modules, but it becomes difficult to accurately position at the fixing point
Solution Approach 1:
The fixing groove is designed and formed in advance on the battery rack case before the rack is assembled or filled with battery modules. This preliminary structural preparation ensures that even when the rack is fully loaded with heavy battery modules, the pre-positioned fixing groove enables accurate and easy positioning at the installation site without complicating the installation process.
3Ease of operation
If the battery rack structure is simplified for easy installation, then installation becomes easier, but the structural strength to protect battery modules may be reduced
Solution Approach 1:
The patent applies segmentation by dividing the fixing function into a dedicated fixing groove structure that is integrated into the rack case. This segmented approach allows the rack case to maintain its protective strength while the specific fixing groove feature provides the simplified installation capability. The fixing groove is a distinct structural element that handles the positioning function without compromising the overall structural integrity of the rack case.
