Clamshell Hood Fender Mount Bracket Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to secure the strength of the fender mounting structure in vehicles equipped with a clamshell type hood, which requires a robust mounting bracket system to accommodate the increased size of the hood while maintaining design advantages and fuel efficiency.
Innovation Solution
A fender mounting structure that includes a support bracket assembly with inner and outer flanges, featuring upper and lower support brackets and fender mounting brackets, providing a secure and reinforced mounting system for the fender panel, specifically designed for vehicles with clamshell type hoods, enhancing the assembly quality and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a clamshell type hood with increased size is applied to cover the vehicle width, then the design advantage and fuel efficiency are improved, but the strength requirement of the fender mounting bracket increases
Solution Approach 1:
The fender mounting bracket is divided into multiple segments: an upper support bracket connected to the fender apron upper member, a lower support bracket disposed below the upper support bracket, and a fender mounting bracket assembly that connects to the fender panel. This segmentation distributes the load and strengthens the overall mounting structure.
Solution Approach 2:
The mounting structure is extended outward from the fender apron upper member along the vehicle width direction by adding the outer flange and positioning the fender mounting bracket assembly outward. This dimensional extension provides a more robust mounting path that increases strength while accommodating the clamshell hood design.
2Adaptability or versatility
If the fender parting line is positioned on the upper part of the fender apron, then a separate fender mounting bracket is required, but the structural complexity increases
Solution Approach 1:
The upper support bracket and lower support bracket are merged into a single integrated support bracket assembly that is mounted as one unit on the fender apron upper member. This reduces the number of separate components and simplifies the overall structure while still providing the necessary strength for the clamshell hood configuration.
Solution Approach 2:
The support bracket assembly serves multiple functions: it provides structural support for the fender mounting bracket, connects to the fender apron upper member, and accommodates the outward positioning of the fender. This multi-functionality reduces the need for additional separate components.

AI summary
A fender mounting structure of a vehicle includes: a fender mounting bracket assembly; and a support bracket assembly that includes an inner flange formed toward inside and an outer flange formed outside in a width direction of the vehicle. In particular, the support bracket assembly is mounted through the inner flange on an outer side of a fender apron upper member along the width direction and disposed along the width direction between the fender apron upper member and a mount end of a fender panel. The fender mounting bracket assembly is mounted on the outer flange of the support bracket assembly and connected to the mount end of the fender panel.
