Vehicle Lamp Bracket Aiming Mechanism for Optical Module Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle headlamps with multiple optical modules, achieving accurate aiming is challenging due to large deviations in the displacement of optical modules at both ends when aiming is performed collectively, especially when modules are linearly arranged.
Innovation Solution
A vehicle lamp design featuring a first bracket for widthwise aiming and a second bracket for lengthwise aiming, with movable pushers and connectors allowing each optical module to be individually adjusted, ensuring precise alignment by rotating and translating the brackets relative to the optical modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If collective aiming is performed on all optical modules, then the aiming process is simplified, but the displacement deviation of optical modules at both ends becomes large
Solution Approach 1:
The patent divides the aiming adjustment into two independent segments: widthwise aiming for the entire array and lengthwise aiming for individual modules. This segmentation allows each optical module to be adjusted independently in the lengthwise direction while maintaining group adjustment in the widthwise direction, thereby resolving the contradiction between operational simplicity and aiming precision.
Solution Approach 2:
The patent introduces a second bracket as an intermediary component between the first bracket and the optical modules. This second bracket enables individual lengthwise aiming adjustment for each module without affecting the overall widthwise aiming configuration, thus maintaining both ease of operation and high precision.
2Manufacturing precision
If individual aiming is performed for each optical module, then aiming accuracy is improved, but the device complexity increases
Solution Approach 1:
The second bracket is designed with universal applicability to work with all optical modules in the array. It provides a standardized interface and adjustment mechanism that can be applied to each module uniformly, enabling individual aiming without requiring unique complex mechanisms for each module, thus controlling device complexity.
Solution Approach 2:
The patent employs a nested bracket structure where the second bracket is positioned between the first bracket and the optical modules. This nesting arrangement allows the individual adjustment mechanism to be integrated within the existing bracket framework, minimizing additional complexity while achieving precise individual aiming.
3Volume of moving object
If optical modules are linearly arranged, then the lamp structure is compact, but the displacement deviation at both ends becomes especially large
Solution Approach 1:
The patent applies local quality adjustment through the second bracket, which enables each optical module to have its own lengthwise aiming adjustment capability. This local adjustment mechanism compensates for the increased displacement deviation at the ends of linearly arranged modules, ensuring uniform aiming precision across all modules while maintaining the compact linear structure.

AI summary
A lamp for a vehicle includes a plurality of optical modules, a first bracket arranged behind the plurality of optical modules, the first bracket performing aiming in a first direction for the plurality of optical modules, and a second bracket arranged between the plurality of optical modules and the first bracket, the second bracket performing aiming in a second direction that is orthogonal to the first direction for each of the plurality of optical modules. In particular, the second bracket is movably coupled to the first bracket to allow each of the plurality of optical modules to be aimed in the second direction as the second bracket moves.
