Battery Box Buffer Structure for EV Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The vibration of electric vehicle battery boxes during operation causes safety issues and reduces the service life of both the box cover and the batteries, as excessive vibration can damage the components and lead to electrolyte mixing within the batteries.
Innovation Solution
Incorporating buffer members between the beam and the box cover in the battery box, which are connected to the beam to absorb and mitigate the vibration, thereby preventing damage to the box cover and batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the box cover is directly connected to the beam, then the structural strength is improved, but the vibration resistance deteriorates
Solution Approach 1:
The patent introduces a buffer member as an intermediary component between the box cover and the beam. This buffer member serves as a mediator that transmits load while isolating vibration, resolving the contradiction between maintaining structural strength and reducing vibration transmission to the box cover and its contents.
2Manufacturing precision
If rigid connection is used between box cover and beam, then the manufacturing precision is improved, but the reliability deteriorates
Solution Approach 1:
The patent changes the connection parameter from rigid to flexible by introducing the buffer member. This allows the connection to maintain precise positioning while accommodating vibrations and deformations, thereby improving reliability and service life without sacrificing manufacturing precision.
