Vehicle Front Structure Linking Bracket for Attachment Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle front structures face challenges in securing sufficient rigidity at the attachment portions between the instrument panel reinforcement and the vehicle body, particularly when connected to rigid plates.
Innovation Solution
A vehicle front structure is designed with a die-cast main framework that integrally includes a dash portion and front pillar portions, an outer panel forming an aesthetic surface, and an instrument panel reinforcement linked by a linking bracket, with fastening directions differing for the reinforcement and bracket to enhance rigidity and reduce parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the instrument panel reinforcement is attached to rigid vehicle body panels, then the attachment structure is simple, but the rigidity of the attachment portion cannot be sufficiently secured
Solution Approach 1:
A linking bracket is introduced as an intermediary component between the instrument panel reinforcement and the main framework. This bracket enables effective force transmission and secures attachment rigidity while maintaining structural clarity through its L-shaped configuration that connects the reinforcement to the die-cast framework.
Solution Approach 2:
The patent combines different materials with complementary properties: the main framework is die-cast for high rigidity and strength, while the linking bracket uses a material optimized for attachment connectivity. This composite approach allows each component to be optimized for its specific function, achieving overall attachment rigidity.
2Strength
If multiple separate fasteners are used to attach the instrument panel reinforcement and linking bracket to the main framework, then the attachment strength is sufficient, but the number of parts increases
Solution Approach 1:
The patent merges the attachment functions into integrated fastening structures where the linking bracket and instrument panel reinforcement are fastened together, and the main framework is clamped between the outer panel and linking bracket. This consolidation reduces the number of separate fasteners while maintaining sufficient attachment strength through the combined fastening system.
3Stability of the object's composition
If the outer panel is fastened to the main framework, then the aesthetic surface is secured, but the structural complexity increases
Solution Approach 1:
The patent segments the fastening system into distinct functional zones: the outer panel is fastened to the main framework at specific locations to secure the aesthetic surface, while the linking bracket handles the instrument panel reinforcement attachment. This segmentation allows each fastening connection to be optimized for its specific purpose without unnecessary complexity.

AI summary
The vehicle front structure includes a dash portion disposed at the vehicle front portion and partitioning the vehicle cabin and the outside of the vehicle cabin, and a pair of right and left front pillar portions connected to both end portions of the dash portion in the vehicle width direction and extending in the vehicle vertical direction, and a die-cast main framework integrally formed therewith, an outer panel disposed outside the main framework in the vehicle width direction and configured to constitute an aesthetic surface and fastened to the main framework, an instrument panel reinforcement extending in the vehicle width direction between the pair of right and left front pillar portions in the vehicle cabin, and a linking bracket connecting the main framework and the instrument panel reinforcement.
