Pivotable Battery Support Structure for Heavy Vehicle Frame Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of efficiently and conveniently positioning and assembling large, heavy traction batteries in heavy-duty vehicles is significant due to their substantial weight and size, necessitating improved suspension systems for efficient assembly and disassembly.
Innovation Solution
A battery suspension arrangement with a pivotable connection to the vehicle frame, allowing the second elongated member to pivot and slide below frame members, enabling pre-assembly of the energy storage arrangement before final attachment, and incorporating pivot joints and bushings for stability and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rigid fixed connections are used to attach the battery support structure to the vehicle frame, then structural stability is improved, but assembly complexity and time consumption increase due to the need for precise alignment and multiple fastening operations
Solution Approach 1:
The connection structure transitions from a fixed rigid state to a pivotable state during assembly, then to a fixed locked state after positioning. This parameter change allows the connection to be flexible during assembly (reducing complexity) and rigid during operation (ensuring stability).
Solution Approach 2:
The connection between the battery support structure and vehicle frame is made dynamic through the pivotable connection, allowing movement from an unattached position to a positioned state, and finally to a locked fixed state. This dynamic capability simplifies assembly while maintaining operational stability.
2Manufacturing precision
If the battery support structure is assembled in place on the vehicle, then positioning accuracy is improved, but assembly time increases due to the need for precise alignment of multiple components during installation
Solution Approach 1:
The battery support structure is pre-assembled as a complete unit on the ground with all components properly positioned, then transported to the vehicle as a single integrated assembly. This preliminary action eliminates the need for complex in-vehicle alignment operations, significantly reducing assembly time while maintaining positioning accuracy through the pivotable connection mechanism.
3Reliability
If the battery support structure uses multiple fixed connection points to the vehicle frame, then structural stability is improved, but ease of assembly and disassembly deteriorates due to the need to secure multiple fastening points
Solution Approach 1:
The connection system uses a pivotable joint that allows the battery support structure to be easily swung into position and then locked, replacing multiple fixed fastening operations with a single dynamic positioning and locking action. This maintains structural stability while dramatically improving ease of assembly and disassembly.
