Vehicle Shock Absorber Support Box Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection structure between the cowl inner lower panel and the reinforce panel in vehicle front shock absorbers is inefficient in providing sufficient supporting force for various loads, leading to deformation and poor handling stability due to lack of separate connection members for twisting and bending loads.
Innovation Solution
A box-type cross-section structure is formed by integrating the cowl inner lower panel and the reinforce panel, with both side end portions connected to the shock absorber supporting panels, and a support panel is added to cover the front portion of the shock absorber supporting panels, enhancing load distribution and supporting force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cowl inner lower panel and reinforce panel are connected merely by flanges to the shock absorber supporting panels, then the structure is simple and easy to manufacture, but the supporting force for various loads is insufficient leading to deformation
Solution Approach 1:
The connection structure is divided into multiple segments: the original flange connections are retained, and additional connection members (such as reinforcement brackets or support beams) are introduced at strategic locations on the shock absorber supporting panels. This segmentation allows the structure to maintain ease of manufacture while distributing loads more effectively across multiple connection points, preventing deformation under various driving conditions.
2Device complexity
If only flanges of the cowl inner lower panel and reinforce panel are welded to the shock absorber supporting panels, then the device complexity is low, but the structure cannot provide sufficient supporting force for twisting and bending loads
Solution Approach 1:
Intermediary connection members (such as reinforcement brackets, support beams, or stiffening ribs) are introduced between the cowl inner lower panel/reinforce panel and the shock absorber supporting panels. These intermediaries act as mediators that transfer and distribute twisting and bending loads, enhancing handling stability without significantly increasing overall device complexity.
3Device complexity
If the shock absorber supporting panels are connected merely by flanges, then the structure is simple, but the loads from various directions cannot be easily distributed leading to poor handling performance
Solution Approach 1:
The connection structure is enhanced by adding elements in additional spatial dimensions. For example, vertical stiffening ribs are added to the horizontal flange connections, or three-dimensional reinforcement brackets are introduced to create a more robust spatial framework. This dimensional enhancement allows loads from various directions (up-down, left-right, forward-backward) to be distributed more effectively, improving handling performance while maintaining reasonable structural simplicity.

AI summary
Provided is a strength reinforcement device for a front shock absorber of a vehicle to provide a sufficient supporting force in spite of a load transferred to the front shock absorber. To this end, a cowl inner lower panel and a reinforce panel which form a box-shape cross-section structure are provided and their both side end portions are integrally connected to shock absorber supporting panels. A support panel is integrally formed in front end portions of both side ends of the cowl inner lower panel to cover and be integrally connected to the front portions of the shock absorber supporting panels, thereby easily distributing the loads transferred in various directions from the shock absorber supporting panels engaged with the front shock absorbers and providing a sufficient supporting force for the shock absorber supporting panels.
