Vehicle Display Assembly Fixing Structure for Rear-Impact Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased size and weight of display assemblies in vehicles pose a risk of movement towards the occupant side during a rear collision due to inertia, as they are fixed to the instrument panel base via bolts, which can transmit impact and cause displacement.
Innovation Solution
A fixing structure that includes first and second brackets with internal and external threads, securely fastening the display assembly to the instrument panel base, using screws to prevent movement during collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the display assembly is fixed to the instrument panel base using bolts, then the display assembly can be securely mounted, but during a rear collision the impact is transmitted through the bolts causing the display assembly to move toward the occupant side due to inertia
Solution Approach 1:
A rubber buffer is introduced as an intermediary component between the display assembly and the instrument panel base. This buffer absorbs and attenuates impact forces during rear collisions, preventing the direct transmission of shock through the fixing bolts to the display assembly, while still maintaining secure mounting under normal conditions
Solution Approach 2:
The rubber buffer is pre-installed in the fixing structure to provide cushioning before impact occurs. This beforehand cushioning prepares the system to absorb collision forces, reducing the likelihood of the display assembly moving toward the occupant side during rear-end impacts

AI summary
A fixing structure of a display assembly to an instrument panel of a vehicle, includes: an instrument panel base of the vehicle as a vehicle frame; one or more first brackets including: a first portion to which a back surface of the display assembly having a display section whose screen is disposed toward an interior side of a cab of the vehicle is fixed, and a second portion extending from the first portion to a front side of the vehicle and fastened to the instrument panel base with an external thread; and an internal thread portion that fixes the one or more first brackets to the instrument panel base with the external thread.
