Headlamp-Mounted Vehicle Camera Alignment With Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle camera mounting structures, such as those securing cameras to the lower bracket of a front fork, require cumbersome labor for aligning the imaging direction, and subject the camera to significant vibrations.
Innovation Solution
A vehicle camera mounting structure that secures the camera to a headlamp, allowing concurrent adjustment of the imaging direction with the headlamp's illumination, and utilizing rubber mounts to minimize vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera is secured to the lower bracket that supports the front fork, then the camera can be mounted to the vehicle, but the alignment of the imaging direction requires cumbersome labor and visual checking
Solution Approach 1:
The patent employs visual feedback mechanisms during the headlamp aiming process to guide camera alignment. The headlamp's illumination pattern serves as a reference for adjusting the camera's imaging direction, allowing operators to achieve proper alignment through observable feedback rather than trial-and-error visual checking of camera images alone.
Solution Approach 2:
The headlamp assembly serves as an intermediary structure that facilitates camera mounting and alignment. By securing the camera to the headlamp, which has a defined aiming mechanism, the patent leverages the headlamp's existing adjustment capabilities and visual references to simplify camera alignment, rather than directly mounting the camera to the front fork bracket.
2Reliability
If the camera is secured to the lower bracket that supports the front fork, then the camera can be mounted to the vehicle, but the camera is subjected to significant vibrations
Solution Approach 1:
The headlamp assembly acts as an intermediary mounting structure between the front fork and the camera. The headlamp is secured to the front fork bracket, while the camera is secured to the headlamp, creating a buffered connection that reduces direct transmission of vibrations from the front fork to the camera.
Solution Approach 2:
The patent anticipates vibration issues by designing the mounting structure to inherently reduce vibration transmission. The headlamp assembly, with its separate mounting interface and positioning, serves as a cushioning element that isolates the camera from high-vibration areas near the front fork, protecting the camera before vibrations can cause imaging instability.
3Productivity
If the camera is secured to the headlamp, then the imaging direction can be adjusted concurrently with headlamp aiming, but the camera mounting structure becomes more complex
Solution Approach 1:
The patent merges the camera mounting function with the headlamp assembly. By integrating the camera mounting structure into the headlamp, the patent combines two functions (headlamp mounting and camera mounting) into a single structural solution, allowing concurrent adjustment of both headlamp illumination direction and camera imaging direction through the same aiming mechanism.
Solution Approach 2:
The headlamp assembly is designed to serve multiple functions: it provides illumination, serves as a mounting structure for the camera, and provides a reference frame for alignment. This multi-functionality allows the same structural elements to facilitate both headlamp aiming and camera alignment, improving adjustment efficiency without requiring entirely separate mounting and adjustment systems.

AI summary
A vehicle camera mounting structure of the present disclosure is provided in a saddle-riding vehicle such as a motorcycle. The structure includes a camera 30 which captures an image of an area in front of the vehicle and a headlamp 14 which illuminates an area in front of the vehicle. The camera 30 is secured to the headlamp 14. For instance, the camera 30 is secured to a lower end of the headlamp 14. It is thereby possible to reduce the labor required to adjust the imaging direction of the camera 30, by allowing the camera 30 to be oriented in alignment concurrently during an aiming process for the headlamp 14.
