Battery Pack Bracket Assembly for Secure Serviceable Frame Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery pack attachment systems for electrified vehicles do not facilitate easy servicing, as they often require significant disassembly of the vehicle to access the battery pack.
Innovation Solution
A battery pack attachment assembly that includes a battery pack bracket with a flange that is received within a pocket of a vehicle frame bracket, allowing for secure attachment and easy removal of the battery pack for servicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery pack is securely attached to the vehicle frame using conventional attachment systems, then the battery pack is firmly fixed, but significant disassembly of the vehicle is required to access the battery pack for servicing
Solution Approach 1:
The attachment system is divided into separate components: a battery pack bracket with flange that attaches to the battery pack, and a vehicle frame bracket with pocket that attaches to the frame. This segmentation allows the battery pack bracket to be independently removed from the battery pack, enabling service access without complete disassembly while maintaining secure attachment through the interlocking flange-pocket mechanism
Solution Approach 2:
The flange-pocket interface acts as an intermediary mechanism between the battery pack and vehicle frame. The flange extends from the battery pack bracket and is received within the pocket of the frame bracket, creating a reversible mechanical connection that provides secure attachment during operation but allows easy removal when servicing is needed
2Ease of repair
If the battery pack is easily removable for servicing, then service access is improved, but the secure attachment and stability during operation may be compromised
Solution Approach 1:
The attachment system transitions from a static permanent connection to a dynamic reversible connection. The flange-pocket interface allows the system to be securely attached during operation (stable state) and easily removed when needed (transient state), providing both secure attachment and ease of removal through a single mechanical design
