Trailer Battery Frame Layout for Variable Pack Widths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailers require customization to accommodate battery packs of different shapes, posing challenges in mounting and interference with vehicle equipment, especially when the battery pack's specifications no longer meet driving requirements.
Innovation Solution
A trailer design featuring a chassis with a battery frame that includes detachable side bars and crossbars, allowing for the assembly of battery packs with varying widths, and positioning the battery frame lower than the chassis to avoid interference with the trailer's floor and wheel mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size battery frame is used to accommodate battery packs, then the structural simplicity is maintained, but the adaptability to different battery pack shapes is reduced
Solution Approach 1:
The battery frame is divided into a fixed base structure and detachable side bars. The side bars can be independently removed or attached, allowing the frame to be reconfigured for different battery pack widths while maintaining a simple overall structure.
Solution Approach 2:
The side bars are designed to be detachable rather than fixed, enabling the battery frame to dynamically adapt its configuration. This allows the same frame to accommodate multiple battery pack shapes by simply attaching or removing side bars as needed.
2Object-affected harmful factors
If the battery frame is positioned higher on the chassis, then the ease of battery pack installation is improved, but the interference with trailer floor and wheel mechanisms increases
Solution Approach 1:
Instead of positioning the battery frame higher to avoid interference, the design moves the battery frame to a lower position on the chassis. This dimensional change in the vertical direction eliminates interference with the trailer floor and wheel mechanisms while maintaining installation accessibility.

AI summary
A battery frame is fixed to a chassis and a battery pack is assembled to the battery frame. The battery frame includes a pair of crossbars and a pair of side bars. The crossbars extend in the vehicle width direction while being spaced apart in the vehicle front-rear direction, and have both ends in the vehicle width direction fixed to the side members. The side bars extend in the vehicle front-rear direction while being spaced apart in the vehicle width direction, and have front ends and rear ends detachably fixed to the crossbars.
