Vehicle Electric Apparatus Fixing Structure with Impact Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing structures for electric apparatuses in vehicle engine compartments are inadequate in preventing damage during collisions, as they fail to effectively absorb and distribute impact forces, leading to potential exposure of high-voltage components.
Innovation Solution
A fixing structure comprising a tray with a removal mechanism and a protecting plate, where the plate is positioned to abut a structural object behind the electric apparatus when it moves rearward upon impact, deflecting and redirecting the force to prevent collision with the structural object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric apparatus is firmly fixed to the tray using rigid fastening mechanisms, then the stability and reliability of the electric apparatus is improved, but the damage to the electric apparatus during collision increases because the impact force cannot be absorbed or distributed
Solution Approach 1:
The patent applies beforehand cushioning by designing the tray with a curved rear portion that can deform during collision to absorb impact energy. The tray is configured to move rearward upon impact, and the curved portion acts as a cushioning element that deforms to reduce the force transmitted to the electric apparatus, thereby protecting it from damage while maintaining normal stability during operation.
Solution Approach 2:
The patent applies dynamics by making the tray movable rather than completely rigid. The tray is designed to move rearward when subjected to impact force from the front, allowing the system to dynamically respond to collision conditions. This movement capability enables the tray to absorb impact energy through deformation and displacement, reducing the harmful effects on the electric apparatus while maintaining stability during normal static operation.
2Reliability
If a protective cover is added to cover the connector and power cable, then the protection of electrical components is improved, but the device complexity increases
Solution Approach 1:
The patent applies merging by integrating the protective function into the tray itself rather than adding a separate protective cover. The tray is designed with features such as a curved rear portion and lateral extensions that directly provide protection for the electric apparatus, connector, and power cable. This integration combines the mounting function and protection function into a single structure, avoiding the need for additional protective covers and reducing overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The structure effectively reduces the impact force on the electric apparatus, preventing damage and exposure of high-voltage components by redirecting the force, thereby enhancing collision safety.
Implementation Method 1
when the electric apparatus receives a predetermined impact force or more from a front side of the vehicle
Implementation Method 2
the protecting plate is positioned to abut a structural object behind the electric apparatus when it moves rearward upon impact, deflecting and redirecting the force

AI summary
Provided is a fixing structure of an electric apparatus in an engine compartment provided in a front portion of a vehicle. The fixing structure includes a tray, a removal mechanism, and a protecting plate. The tray is fixed in the engine compartment and configured such that the electric apparatus is placed thereon. The removal mechanism is configured to remove the electric apparatus from the tray when the electric apparatus receives a predetermined impact force or more from a front side of the vehicle. The protecting plate is attached to the electric apparatus, and is configured to abut with a structural object placed at a rear side of the vehicle relative to the electric apparatus when the electric apparatus is removed from the tray due to the impact force so as to move rearward.
