Vehicle Front Structure With Detachable Charger Mount Under Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle front structures hinder the deformation of side frames when on-board equipment is positioned between them, impairing impact load absorption.
Innovation Solution
A detachable fixation structure for on-board equipment, allowing it to be detached from side frames upon impact, and a guide mechanism to facilitate its movement, preventing hindrance to side frame deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If on-board equipment is fixed to side frames between the pair of side frames, then the on-board equipment is securely positioned, but the deformation of side frames is hindered when impact load is applied
Solution Approach 1:
The fixation structure transitions from a static fixed state to a dynamic detachable state upon impact. The detachable fixation structure includes a fixation body and a detachment mechanism that allows the on-board equipment to separate from the side frame when subjected to impact load, enabling the side frame to deform and absorb impact energy while maintaining stable positioning during normal operation
Solution Approach 2:
The fixation structure is divided into separable components: a fixation body attached to the on-board equipment and a detachable connection mechanism that interfaces with the side frame. This segmentation allows the fixation to remain intact during normal use but separate when impact occurs, resolving the contradiction between stable positioning and impact absorption
2Volume of moving object
If on-board equipment is positioned between side frames to utilize space, then space utilization is improved, but the side frames cannot deform to absorb impact loads
Solution Approach 1:
The detachable fixation structure enables the on-board equipment to dynamically separate from the side frame under impact conditions. During normal operation, the equipment occupies the space between side frames efficiently. When impact load is applied, the detachment mechanism activates, allowing the side frame to deform and absorb impact energy without being constrained by the positioned equipment

AI summary
The present invention relates to a front structure (1) of a vehicle, which comprises a pair of right-and-left side frames (33) extending in a longitudinal direction, a cross member (34) provided to extend between the side frames (33), and an on-board equipment, for example a non-contact charger (70), positioned between the side frames (33), the on-board equipment having a body portion (74), wherein the on-board equipment comprises front-side fixation portions (76) fixed to the cross member (34) and back-side fixation portions (77) positioned in back of the front-side fixation portions (76) and fixed to the side frames (33) through fixation structures (X) in which the on-board equipment is detachable from the side frames (33) when receiving an impact load applied from a front side of the structure.
