Battery Carrier L-Shaped Locking Mechanism Rear Crash Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle crashes induce forces that can dislodge batteries from their carriers, necessitating enhanced holding power, particularly in the battery clamp mechanism.
Innovation Solution
A battery carrier design that includes a carrier base with holding portions on the rear and side edges and a battery clamp positioned further back, featuring a front locking part and side locking part with plate-like configurations to securely hold the battery's bottom flanges, providing increased rigidity against rearward tilting forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the front locking part uses only a simple pressing structure, then the device complexity is reduced, but the rigidity against rearward tilting forces is insufficient
Solution Approach 1:
The front locking part is designed as a composite structure combining a plate-like front facing portion and a plate-like front pressing portion. This composite configuration creates an L-shaped locking mechanism that provides both rigidity against rearward tilting forces and simplicity in overall design. The plate-like structures distribute crash forces effectively without requiring complex mechanical components.
Solution Approach 2:
The front locking part extends in multiple dimensions with the front facing portion providing frontal engagement and the front pressing portion providing lateral engagement. This multi-dimensional configuration increases rigidity against rearward tilting forces by creating a distributed locking mechanism that resists rotation and displacement, while still maintaining a relatively simple single-piece structure.

AI summary
A battery clamp includes a front locking part (36) configured to lock a front face bottom flange (16F) formed on a bottom of a front face (14F) of a battery (10). During normal operations, a front pressing portion (50) of the front locking part (36) is in contact with a top face of the front face bottom flange (16F). In a rear crash, upon receiving an upward force from the front face bottom flange (16F), the front locking part (36) moves upward and is tilted rearward to bring a front facing portion (48) into contact with the front face (14F) of the battery 10. Not only the front pressing portion (50) but also the front facing portion (48) holds the battery (10), so that holding power can be enhanced.
