Sensor Bracket Segmentation for Camera Hood Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transport equipment with camera-based external environment detection systems face challenges in maintenance due to enlarged reflected wave reducing structures, which increase the number of parts that need to be attached and detached, complicating maintenance work around the sensor hood.
Innovation Solution
The design incorporates a sensor bracket with a separable segment body for the reflected wave reducing structure, allowing for fewer parts to be attached and detached during maintenance, while maintaining the strength and functionality of the fixed body, and includes features like elastic deformation parts and attachment guides to improve workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the reflected wave reducing structure is enlarged to match the wide viewing angle of modern cameras, then the stray light shielding performance is improved, but the number of parts to be attached and detached during maintenance increases
Solution Approach 1:
The surface forming part is divided into a fixed body (including the attachment part) and a segment body. The segment body can be detached from the fixed body to provide access to the inside of the lens hood for maintenance work, while the fixed body remains attached to the vehicle body. This segmentation allows the reflected wave reducing structure to be enlarged without increasing the number of parts that need to be completely detached during maintenance.
2Ease of operation
If the entire surface forming part with the reflected wave reducing structure is made detachable for maintenance access, then maintenance workability is improved, but the number of parts to be attached and detached increases
Solution Approach 1:
The surface forming part is segmented into a fixed body that remains attached to the vehicle body and a segment body that can be detached. This allows maintenance personnel to access the inside of the lens hood by detaching only the segment body, rather than detaching the entire surface forming part. The fixed body provides structural support and maintains attachment to the vehicle, reducing the number of parts that need to be handled during maintenance.
3Object-affected harmful factors
If the lens hood structure is enlarged to provide better coverage, then the stray light reduction effectiveness is improved, but the weight of the sensor bracket increases
Solution Approach 1:
The lens hood is divided into a fixed body and a segment body, allowing the reflected wave reducing structure to be enlarged for better stray light coverage while distributing the weight across two separate components. The segment body can be detached and replaced if needed, and the fixed body remains attached to the vehicle body, providing structural support without requiring the entire structure to be heavy-duty.

AI summary
A vehicle and a camera bracket include a lens hood which surrounds a detection space of an external environment detection camera, in which the lens hood includes a reflected wave reducing structure on at least a portion of a surface facing the detection space, and a bottom surface forming part which forms a surface (bottom surface) having the reflected wave reducing structure on the lens hood includes a fixed body having a portion (a fixed-side structure portion) of the reflected wave reducing structure and fixed to a vehicle main body, and a segment body having the other portion (a segment-side structure portion) of the reflected wave reducing structure and configured to be separable from the fixed body.
