Vehicle Front Structure With Adjustable Headlamp Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle front structures suffer from assembly errors between headlamps and exterior members due to dimensional inaccuracies, leading to impaired vehicle symmetry and appearance.
Innovation Solution
A support member with inclined surfaces and a support mechanism that allows position adjustment of headlamp attachment portions in the vehicle width direction, ensuring accurate alignment with exterior member surfaces through contact and fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the headlamp unit is assembled to the radiator support member using the main hook portion and main stop portion, then the headlamp unit can be fixed to the vehicle body, but assembly errors occur due to dimensional inaccuracies of the exterior member
Solution Approach 1:
The attachment portion is designed to be movable relative to the body portion in the vehicle width direction through a support mechanism (elongated hole and guide groove), allowing dynamic adjustment during assembly. This enables the headlamp to self-align with the exterior member by moving along the inclined surface contact path, compensating for dimensional variations in the exterior member while maintaining reliable fixation when fastened.
2Ease of manufacture
If the exterior member is assembled to the radiator support, then the design surface is completed, but assembly errors between headlamp and exterior member increase due to dimensional error of the exterior member
Solution Approach 1:
The attachment portion serves as an intermediary element between the body portion and the headlamp. It includes an inclined surface that contacts the exterior member and another inclined surface that contacts the headlamp, creating a mechanical interface that guides and aligns both components. This intermediary structure transfers and协调s the positional relationships, ensuring accurate alignment even when the exterior member has dimensional variations.
3Stability of the object's composition
If the attachment portions are fixed to the body portion, then the structure is stabilized, but position adjustment for alignment is restricted
Solution Approach 1:
The support mechanism using elongated holes and guide grooves creates a dynamic connection that allows movement in the vehicle width direction while restricting movement in other directions. This enables the attachment portion to adjust its position for alignment during assembly, then maintains stability when fastened, achieving both adaptability and structural stability.
4Device complexity
If the vehicle front structure uses fixed attachment positions, then the structure is simple, but assembly errors impair vehicle symmetry and appearance
Solution Approach 1:
The attachment mechanism incorporates movable attachment portions that can adjust position in the vehicle width direction through elongated holes and guide grooves. This simple dynamic mechanism allows the headlamp to self-align with the exterior member, ensuring symmetrical appearance without requiring complex adjustment devices or precision manufacturing of the exterior member.

AI summary
A front structure of a vehicle includes a pair of headlamps each of which having a second inclined surface, an exterior member having a first inclined surface, and a support member. The support member includes: a body portion to which the exterior member is attached, a pair of attachment portions that are connected to both ends of the body portion in the vehicle width direction and to which the headlamps are attached, and a fastening portion that fastens the attachment portions to the body portion at a position where the first and second inclined surfaces are in contact with each other. The support member allows a position change of the attachment portions with respect to the body portion in the vehicle width direction in a state where the body portion and the attachment portions are not fastened by the fastening portion, and restricts the position change in a different direction.
