Camera Mounting Structure with Segmented Angle-of-View Hood
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera mounting structures for vehicles near the front windshield glass experience variations in the position of the angle-of-view hood member with respect to the camera lens due to inconsistent attachment methods, affecting the camera's field of view and reliability.
Innovation Solution
A camera mounting structure that includes a bracket attached to the vehicle's windshield glass, with an angle-of-view hood member featuring fastening and catch portions securely fastened and caught on the bracket, utilizing claw portions spaced across the vehicle width to prevent positional variation, ensuring the hood member's stable positioning relative to the lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the angle-of-view hood member is attached to the bracket using only a fastening portion, then the attachment process is simple, but the position of the angle-of-view hood member with respect to the lens varies
Solution Approach 1:
The angle-of-view hood member is divided into multiple attachment points: a fastening portion at the rear end and a catch portion at the front end. This segmentation allows the member to be securely attached at multiple locations along its length, preventing positional variation while maintaining a relatively simple attachment process.
Solution Approach 2:
The attachment system transitions from a single-point fastening to a multi-point fastening system that extends along the length of the angle-of-view hood member. By distributing attachment points from the rear end to the front end, the system achieves better positional control without significantly increasing complexity.
2Reliability
If the angle-of-view hood member is securely fastened to prevent position variation, then the camera performance is improved, but the attachment structure becomes more complex
Solution Approach 1:
The attachment structure is segmented into two functional portions: a fastening portion for secure attachment and a catch portion for positional constraint. This segmentation achieves reliable camera performance through multi-point attachment while keeping each individual component relatively simple in design.
Solution Approach 2:
The catch portion acts as an intermediary element that works in conjunction with the fastening portion to achieve secure attachment. This intermediary structure helps constrain the angle-of-view hood member's position without requiring a completely complex attachment mechanism.

AI summary
A camera mounting structure includes: a bracket that is attached to a vehicle upper side of an inner surface of a front windshield glass; a camera that is supported by the bracket and detects information about the surroundings of a vehicle; and an angle-of-view hood member that has a fastening portion fastened to the bracket and a catch portion caught on the bracket and is disposed on a vehicle front lower side of a lens of the camera.
