Stepped Vehicle Floor Structure for Pedal Space and Battery Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle body structures face challenges in optimizing pedal operability while accommodating a battery unit, as floor position adjusters can obstruct battery mounting and reduce cruising range.
Innovation Solution
A vehicle body structure with a front floor panel positioned higher than the rear floor panel, allowing the heel of the pedal operator to be elevated, reducing the angle between the lower leg and the floor, and incorporating a battery placement below the front floor panel to maximize space utilization, with hinge pillars overlapping the battery for impact protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a floor position adjuster is provided to raise the heel position for improved pedal operability, then pedal operability is improved, but the capacity for mounting batteries decreases and the structure becomes more complex
Solution Approach 1:
The floor panel is divided into two distinct segments: a front floor panel positioned higher to support the heel for pedal operation, and a rear floor panel positioned lower to create space for battery mounting. This segmentation allows each zone to serve its specific function without interfering with the other, resolving the contradiction between pedal operability and battery capacity.
Solution Approach 2:
Different heights are assigned to different regions of the floor panel. The front region is elevated to improve pedal operability by raising the heel position, while the rear region is kept lower to maximize battery mounting space. This local differentiation of quality (height) optimizes both functions simultaneously.
2Ease of operation
If a floor position adjuster with lifting/lowering mechanism and lock mechanism is incorporated, then pedal operability is improved, but the device complexity increases and space for battery mounting decreases
Solution Approach 1:
The complex lifting/lowering mechanism and lock mechanism are extracted and removed from the system. Instead of using an adjustable floor position system, the patent employs a fixed two-level floor panel structure that achieves the same pedal operability improvement without requiring complex mechanical components.
Solution Approach 2:
Instead of making the floor panel adjustable through complex mechanisms, the invention inverts the approach by creating a fixed stepped structure where the front floor panel is permanently positioned higher than the rear floor panel, achieving the desired heel elevation without any adjustment mechanisms.
3Duration of action of moving object
If the battery unit is mounted below the floor panel, then the cruising range is extended, but the floor position adjuster becomes an obstacle and decreases the battery mounting capacity
Solution Approach 1:
The floor panel structure transitions from a single-plane configuration to a two-level stepped configuration. By utilizing the vertical dimension to create height differentiation between the front and rear floor panels, the design maximizes the available volume below the floor for battery mounting while maintaining the elevated heel position for pedal operation.

AI summary
A vehicle body structure includes a front floor panel and a rear floor panel provided at the rear of the front floor panel. The front floor panel is positioned higher than the rear floor panel. A front battery that supplies electric power to the traction motor is arranged below the front floor panel.
