Hybrid Vehicle Power Equipment Recessed Floor Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When power equipment like batteries is installed on a floor panel, it raises the seat position, hindering low-flooring designs, and recessing the equipment can lower the waterproof line, posing a challenge in maintaining both low-flooring and waterproofing.
Innovation Solution
A vehicle design featuring a recessed power equipment containing portion in the floor panel with a frame member and holding member that suspends and fixes the power equipment, maintaining it above the floor surface while ensuring a high waterproof line, and also absorbing deformation during collisions and protecting adjacent components like air-conditioning ducts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power equipment is installed on the floor panel according to the floor surface, then the power equipment is securely positioned, but the seat position becomes higher which hinders low-flooring
Solution Approach 1:
The invention transitions from a two-dimensional floor surface installation to a three-dimensional recessed structure. The power equipment is installed in a recessed portion of the floor panel, utilizing the vertical dimension to accommodate the equipment while keeping the floor surface level, thereby enabling low-flooring design
2Length of stationary object
If a recessed power equipment containing portion is provided in the floor panel to house the power equipment, then low-flooring is achieved, but the waterproof line of the power equipment is lowered
Solution Approach 1:
The invention segments the floor panel structure into multiple functional zones: a recessed portion for housing power equipment and a separate waterproofing structure. The waterproof line is positioned on the lateral surface of the recessed portion rather than at the bottom, creating a distinct separation between the equipment housing function and the waterproofing function
Solution Approach 2:
The lateral surface of the recessed portion acts as an intermediary structure that simultaneously serves as the boundary of the equipment housing and the support for the waterproof line. This intermediary structure allows the waterproof line to be positioned at a higher location while still protecting the recessed equipment containing portion
3Length of stationary object
If the power equipment is suspended above the floor surface using a frame member and holding member, then both low-flooring and high waterproof line are achieved, but the device complexity increases
Solution Approach 1:
The holding member is designed with multi-functionality: it serves as both the suspension support for the power equipment and as part of the waterproofing structure. The lateral surface of the holding member provides the support for the waterproof line, combining structural support and waterproofing functions into a single component, thereby reducing overall device complexity

AI summary
A vehicle includes: a power equipment; a floor panel having a recessed power equipment containing portion that houses the power equipment; and a frame member that suspends and holds the power equipment, wherein the frame member is fixed to the floor panel through a holding member so that a part of the power equipment protrudes from the floor panel, the holding member has an upper end surface, a lower end surface, and a vertical wall that connects the upper end surface and the lower end surface to each other. The frame member is fastened to the upper end surface of the holding member, and the floor panel is fastened to the lower end surface of the holding member.
