Battery Support Structure With Restraint Force Against Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery support structures fail to adequately suppress rattling and maintain stable electrical connections due to vehicle vibrations, particularly when vibrations are not aligned with the elastic expansion and contraction direction of the battery unit.
Innovation Solution
A battery support structure that includes a restraint member to draw the battery with a predetermined force, using a reaction force to stabilize the battery and prevent rattling, while maintaining electrical connections through a latch and link mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery is supported by a detachable unit on the vehicle main body, then the battery can be easily installed and removed, but vehicle vibration causes the battery to move relative to the vehicle, making it difficult to suppress rattling
Solution Approach 1:
The restraint member is configured to be movable between a first position where it restrains the battery and a second position where it releases the battery. This dynamic mechanism allows the system to switch between stable support during vehicle operation and easy removal when needed, resolving the contradiction between operational ease and stability.
2Adaptability or versatility
If the battery unit has an elastic expansion and contraction structure, then the battery can maintain connection during expansion and contraction, but when vibration direction is not aligned with the elastic direction, the battery moves relative to the vehicle and cannot be properly supported
Solution Approach 1:
The restraint member provides universal restraint functionality that works regardless of vibration direction. It can restrain the battery in any direction (front-rear, left-right, or up-down) while the battery maintains its elastic expansion and contraction capability in its original direction, combining multi-directional stability with adaptive flexibility.
3Stability of the object's composition
If the battery is drawn with a predetermined force by the restraint member, then the battery receives reaction force to suppress rattling, but the structure becomes more complex
Solution Approach 1:
The restraint member utilizes the battery's own weight and the natural reaction force generated when the battery is drawn toward the vehicle main body to achieve stabilization. The system serves itself by using the battery's mass and the restraint mechanism's geometry to generate the necessary counteracting forces without requiring additional active components or complex control systems.

AI summary
A battery support structure for supporting, on a vehicle, a battery. The battery support structure includes a restraint member that restrains the battery in a state of the battery being drawn so that, when the battery is drawn with a predetermined force, the battery receives a reaction force against the predetermined force. For example, the restraint member is disposed to face both side positions of a location where a connector of the battery is disposed.
