Battery Pack Mounting With Elastic Support for Vibration Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle battery pack fastening mechanisms, which rely on simple fastening members, fail to adequately suppress vibrations during travel, leading to potential dislodging and reduced ride comfort.
Innovation Solution
Incorporating an elastic member between the battery pack and fixing members, which is compressed to provide elastic support, enhancing rigidity and sealing gaps while using bolts for secure fastening, thereby reducing vibrations and improving attachability and detachability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple fastening mechanism is used to attach the battery pack to the rockers, then the attachability and detachability are improved, but the battery pack vibrates during traveling
Solution Approach 1:
The patent uses a composite fastening structure combining rigid fastening members (bolts) with elastic members (rubber elements) to create a hybrid connection system. This composite approach allows the rigid bolts to provide secure attachment while the elastic rubber elements absorb vibrations, resolving the contradiction between ease of operation and vibration suppression.
Solution Approach 2:
The elastic member acts as an intermediary element between the battery pack and the rockers. This mediator component transmits the fastening force while simultaneously absorbing vibrational energy, enabling both secure attachment and vibration reduction without compromising either function.
2Strength
If rigid fastening only is used, then structural strength is improved, but vibration suppression is insufficient
Solution Approach 1:
The fastening system combines rigid fastening members for structural strength with elastic rubber members for vibration absorption. This composite material approach allows simultaneous achievement of high fastening strength and effective vibration suppression.
Solution Approach 2:
The patent converts the harmful vibration into a beneficial damping effect by using the elastic deformation of the rubber members. The vibrational energy that would normally be harmful is instead absorbed and dissipated through the elastic properties of the rubber, transforming a negative factor into a positive vibration suppression mechanism.

Function Achieved in This Case
The elastic support structure effectively suppresses battery pack vibrations, enhances rigidity, and seals gaps to prevent foreign matter ingress, improving both ride comfort and ease of assembly/disassembly.
Implementation Method 1
an elastic member disposed between the battery pack and the fixing members. The elastic member is disposed in a state compressed by the battery pack and the fixing members
