Cabin Front Wall Brace Layout for Dash Panel Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cabin front wall structure of vehicles, particularly the dash panel, suffers from reduced strength due to the integration of accelerator and brake brackets, which are closely located and do not adequately reinforce the panel, especially around the steering column through hole, leading to potential structural weaknesses during collisions.
Innovation Solution
A cabin front wall structure that includes a dash panel with separate accelerator and brake brackets positioned on opposite sides of the steering column hole, connected by a reinforcement member, such as a dash brace, which extends along the vehicle width and overlaps with the brackets to enhance the structural integrity of the dash panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an integral bracket is used to attach both accelerator and brake pedals to the dash panel, then the dash panel can be commonly used across different vehicle configurations, but the structural strength of the dash panel is insufficient, especially around the steering column through hole
Solution Approach 1:
The patent divides the bracket system into separate accelerator bracket and brake bracket components instead of using a single integral bracket. This segmentation allows each bracket to be independently positioned and attached to the dash panel, providing better structural support while maintaining versatility. The separate brackets can be strategically placed to reinforce the dash panel around the steering column through hole while still allowing the same dash panel to be used across different vehicle configurations with varying pedal positions.
2Device complexity
If the accelerator bracket and brake bracket are closely located in an integral structure, then the design is simplified, but the reinforcement effect on the dash panel is insufficient
Solution Approach 1:
The patent utilizes the spatial dimension by positioning the accelerator bracket and brake bracket at different locations on the dash panel, spaced apart in the vehicle width direction. This dimensional separation allows the brackets to provide distributed reinforcement across the dash panel, particularly strengthening the areas around the steering column through hole. The connection member spans across the dash panel surface, creating a triangular support structure that enhances overall rigidity without requiring a complex integral design.

AI summary
A cabin front wall structure of a vehicle includes a dash panel constituting a front wall of a cabin of a vehicle, an accelerator bracket attached to the dash panel, and used for mounting an accelerator pedal, a brake bracket attached to the dash panel at a position spaced from the accelerator bracket in a vehicle width direction, and used for mounting a brake pedal; and a brace (connection member) extending along a surface of the dash panel and configured to connect the accelerator bracket with the brake bracket.
