Vehicle Floor Panel Segmentation for Slope Device Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle bottom structures, the standing-ride region experiences significant load deformation, which can interfere with the movement of slope devices, leading to maintenance challenges due to the need for replacing entire floor panels when deformation occurs.
Innovation Solution
A vehicle bottom structure design featuring a floor panel structure composed of multiple panel segments over floor crossmembers, with the slope device positioned below, allowing for independent replacement of deformed segments and improved maintenance performance by supporting the panel segments with guide rails and varying wall thickness for enhanced rigidity.

Engineering Contradiction Analysis
1Ease of repair
If a single floor panel covers the entire vehicle cabin floor, then the structural integrity is maintained, but maintenance becomes difficult when deformation occurs in the standing-ride region
Solution Approach 1:
The floor panel is divided into multiple panel segments that can be independently replaced. The standing-ride region is covered with separate panel segments rather than a single continuous panel, allowing only the deformed segment to be replaced while maintaining the rest of the floor structure.
2Strength
If the standing-ride region is covered with a floor panel, then the structural support is provided, but the load deformation interferes with the slope device movement
Solution Approach 1:
The floor panel is segmented into multiple independent panel segments. When load deformation occurs in the standing-ride region, only the affected segment deforms while others remain intact, reducing the interference with the slope device and allowing for targeted maintenance.
3Reliability
If the entire floor panel is replaced when deformation occurs, then the structural integrity is restored, but the maintenance workload increases
Solution Approach 1:
The floor panel is divided into multiple replaceable segments. When deformation occurs, only the deformed segment needs to be replaced rather than the entire floor panel, significantly reducing maintenance workload and improving productivity while maintaining structural integrity.
Solution Approach 2:
Only the deformed panel segment is discarded and replaced, while the undamaged segments are recovered and retained in the floor structure. This selective replacement approach maintains structural integrity while minimizing material waste and maintenance costs.

AI summary
A vehicle bottom structure includes a slope device including a slope plate and guide rails, floor crossmembers, and a floor panel structure. The floor crossmembers are arranged at intervals in the vehicle front-rear direction. The slope device is provided between paired floor crossmembers, and the slope device is provided below a standing-ride region. The floor panel structure is provided over the paired floor crossmembers such that the floor panel structure is placed above the slope device and serves as a floor material in the standing-ride region. The floor panel structure includes panel segments extended in the vehicle front-rear direction so as to be provided over the paired floor crossmembers, and the panel segments are shorter than the whole length of the standing-ride region in the vehicle width direction. The panel segments are arranged side by side in the vehicle width direction in the standing-ride region.
