Inverter Buffer Structure for Hybrid Vehicle Collision Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In hybrid vehicles, the inverter is vulnerable to damage during a head-on collision due to direct impact from the deformed radiator core support, leading to potential damage to the inverter case and internal contents.
Innovation Solution
An inverter buffer structure is implemented with a buffer member positioned between the inverter and the radiator core support, which acts as a shock absorber to prevent direct impact and reduce damage by distributing the force of a collision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inverter is disposed in the front engine compartment without a buffer member, then the device complexity is reduced, but the inverter is vulnerable to damage during head-on collision from direct impact by the deformed radiator core support
Solution Approach 1:
A buffer member is introduced as an intermediary element positioned between the radiator core support and the inverter. This buffer member absorbs and distributes the impact force during head-on collision, preventing direct contact between the deformed radiator core support and the inverter, thereby protecting the inverter while adding minimal structural complexity
Solution Approach 2:
The buffer member is pre-installed in the space between the radiator core support and the inverter before collision occurs. This beforehand cushioning structure is designed to deform and absorb impact energy during head-on collision, protecting the inverter from direct impact without requiring complex active protection systems
2Reliability
If the buffer member is added between the inverter and radiator core support, then the inverter is protected from collision damage, but the device complexity and space requirements increase
Solution Approach 1:
The buffer member is designed as a flexible, deformable component that can be made from materials such as foam or elastomeric substances. This flexible structure provides effective impact absorption while occupying minimal space in the engine compartment, protecting the inverter without significantly increasing the overall vehicle dimensions or engine bay complexity
