Vehicle Floor Bracket Layout for Larger Underfloor Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lower part structures with protruding brackets interfere with new components of different shapes or larger sizes when mounted on the lower side of a floor panel, impairing their mounting and potentially causing interference with the road surface.
Innovation Solution
A vehicle lower part structure featuring a floor panel with a convex upward portion and a flat bracket that covers the convex portion from the lower side, allowing for reduced downward projection of the bracket and accommodating new components without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bracket protrudes downward from the floor panel to fasten the battery, then the battery can be securely mounted, but the bracket interferes with new components of different shapes or larger sizes when mounted on the lower side of the floor panel
Solution Approach 1:
The invention moves the fastening mechanism from a downward-protruding bracket to an upward-convex structure on the floor panel. By inverting the spatial arrangement and using the convex portion extending upward with an internal space, the fastening function is achieved without downward projection, allowing new components of various shapes and sizes to be mounted below the floor panel without interference.
2Ease of manufacture
If the bracket protrudes downward from the floor panel, then the current battery can be mounted, but the above ground level of newly mounted batteries is lowered, causing easier interference with the road surface
Solution Approach 1:
Instead of having the bracket protrude downward from the floor panel to support the battery, the invention inverts the approach by creating a convex portion on the floor panel that extends upward. The internal space of the convex portion accommodates the fastening mechanism (nut and bolt shaft), allowing the battery to be mounted below the floor panel at a higher position, thereby reducing interference with the road surface.
3Reliability
If the bracket is designed to project downward from the floor panel, then fastening is achieved, but the bracket structure becomes complex and interferes with component placement flexibility
Solution Approach 1:
The invention merges the floor panel and the fastening structure into a unified design. The convex portion is formed as an integral part of the floor panel, eliminating the need for a separate downward-protruding bracket. The internal space of the convex portion houses the fastening mechanism, combining structural support and fastening functions in a single integrated component.

AI summary
A vehicle lower part structure includes a floor panel, a bracket fixed to the floor panel, and a component mounted on a lower side of the floor panel so as to be fastened by a fastener to the bracket. The floor panel has a convex portion. The bracket is provided so as to cover the convex portion from a lower side. The fastener includes a bolt and a nut. The bolt has a head located on a lower side of the bracket and a shaft extending upward from the head and inserted in a hole formed in the bracket. A distal end of the shaft is located in the internal space of the convex portion.
