Vehicle Front Structure with Non-Contact Charger Load Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle front portion structures with non-contact chargers are inadequate in transmitting collision loads during a front collision, as they do not effectively distribute and absorb the impact energy.
Innovation Solution
A vehicle front portion structure comprising a first and second vehicle body frame extending in the vehicle transverse direction, with a non-contact charger having a power receiving coil, a resin cover, and pair of longitudinal direction frames that extend alongside the coil, allowing for effective load transmission and absorption during collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a non-contact charger is installed at the lower portion of the vehicle front portion, then wireless charging function is achieved, but collision load transmission capability is insufficient
Solution Approach 1:
The non-contact charger is divided into multiple structural components: a housing, a power receiving coil, and a support structure with mounting portions. This segmentation allows each component to be optimized for its specific function while collectively providing both wireless charging capability and collision load transmission path.
Solution Approach 2:
The patent combines the non-contact charger structure with the vehicle front portion framework by providing mounting portions that connect to the vehicle body frame. This merging creates an integrated structure where the charger housing and support elements form part of the collision load transmission path, simultaneously achieving wireless charging function and improving collision load transmission capability.
2Adaptability or versatility
If the power receiving coil is disposed to span over the open portion of the front panel, then wireless charging is enabled, but structural rigidity for collision resistance is reduced
Solution Approach 1:
The patent applies different structural qualities to different regions: the power receiving coil area maintains openness for wireless charging, while the housing and support structure provide localized rigidity and strength. The mounting portions connecting to the vehicle body frame create rigid anchor points, while the central coil region remains accessible for electromagnetic coupling.
Solution Approach 2:
The non-contact charger housing and support structure utilize composite construction combining rigid materials for structural integrity with optimized geometries. The housing provides rigid protection and structural support, while the integrated support structure with mounting portions creates a composite system that maintains rigidity despite the open coil portion.

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 enhances the rigidity and ability to absorb collision energy by transmitting loads through the non-contact charger's longitudinal frames, reducing the risk of damage from curb impacts and improving overall collision resistance.
Implementation Method 1
a power receiving coil that structures the non-contact charger is installed at the bottom surface of the front end portion of a floor panel
