Split Vehicle Battery Service Hole Cover for Compact Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle battery mounting structures require significant seat slide to access service hole covers, compromising workability and potentially exposing the battery to water ingress.
Innovation Solution
A vehicle battery mounting structure with a split service hole cover system, where one cover is detachably attached to the floor and the other is slid to expose it, reducing the required seat slide and incorporating a seal member to prevent water entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the service hole cover is made as a single piece attached to the floor panel, then the sealing structure is simple, but the workability for removing the cover is poor due to narrow space below the front seat
Solution Approach 1:
The service hole cover is divided into a first cover and a second cover. The first cover is fixed to the floor panel, while the second cover is detachably attached, allowing it to be removed independently. This segmentation enables workers to access the service hole more easily by removing only the second cover, improving workability without requiring complex mechanisms.
2Ease of operation
If the front seat is made slidable to expose the service hole cover for easier access, then the workability improves, but the amount of slide required is large
Solution Approach 1:
By dividing the service hole cover into two separate covers (first and second covers), the invention allows workers to access the service hole by removing only the second cover, which is detachably attached. This eliminates the need for large seat sliding movements, reducing the required slide distance while maintaining ease of operation.
3Ease of operation
If the service hole is positioned under the front seat, then the battery mounting structure is compact, but the workability for operating the service plug is poor
Solution Approach 1:
The service hole cover is segmented into a fixed first cover and a detachable second cover. This allows the service hole to remain positioned under the front seat for compact battery mounting, while workers can easily remove the second cover to access and operate the service plug, improving operability without increasing mounting space.
4Ease of operation
If the service hole cover is split into multiple detachable parts, then the workability improves, but the sealing reliability may be compromised
Solution Approach 1:
The service hole cover is divided into a first cover and a second cover, with the second cover being detachably attached to the first cover. This segmentation improves workability by allowing easy removal of the second cover, while the overlapping configuration and sealing structures maintain sealing reliability when both covers are in place.
Solution Approach 2:
The second cover is configured to overlap the first cover in the vehicle longitudinal direction, creating a nested arrangement. This nesting ensures that both covers work together to seal the service hole effectively, maintaining reliability while allowing the second cover to be removed for access.

AI summary
A vehicle battery mounting structure having a service hole cover that closes a service hole the service hole cover includes a rear cover that covers a rear end side of the service hole in a vehicle longitudinal direction and a front cover that covers a front end side of the service hole in the vehicle longitudinal direction. That is, the service hole cover is split into the rear cover and the front cover in the vehicle longitudinal direction. The front cover is detachably attached to a floor upper reinforcement provided on a floor panel by bolts.
