Vehicle Battery Support Clamp With Serrated Anti-Loosening Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery support systems for heavy-duty vehicles face issues with battery retention due to deformation from over-tightening, play and loosening from under-tightening, and vibration-induced nut loosening, leading to noise and potential battery fall.
Innovation Solution
A battery support system featuring a tray with a flange and threaded rod clamping device, where the contact surfaces between the nut and collar have serrations for positive locking, preventing deformation and maintaining preload even under vibrations, combined with an anti-theft device using a bar and arch-shaped rod for secure battery retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flange is tightened too much on the battery, then the battery retention is improved, but the battery will deform under the tightening action
Solution Approach 1:
The patent introduces a flange as an intermediary component between the clamping device and the battery. The flange distributes the clamping force over a larger area of the battery housing, preventing localized deformation while maintaining secure retention. The flange acts as a mediator that transforms the concentrated force from the threaded rod into a distributed pressure on the battery.
2Shape
If the clamp is not tight enough on the battery, then the battery deformation is avoided, but the battery will have play and cause the clamp to loosen or come off
Solution Approach 1:
The patent incorporates a spring element that applies preliminary clamping force to the flange before the vehicle even moves. This pre-load ensures the battery is securely held in position from the start, preventing play and movement that would otherwise cause the clamp to loosen over time. The spring continuously maintains contact pressure to compensate for any settling or thermal expansion.
3Reliability
If the flange is tightened to the optimum on the battery at the time of installation, then the battery retention is optimized, but the vibrations caused by the movement of the vehicle will cause the nut to loosen
Solution Approach 1:
The patent employs a spring-loaded clamping mechanism that provides continuous feedback force on the battery. As the battery settles or moves during vehicle operation, the spring automatically adjusts the clamping force to maintain optimal retention. This dynamic feedback system compensates for vibration-induced loosening by continuously applying corrective pressure through the spring element.
