Sensor Mounting Structure Apron Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting structures for vicinity information detection sensors on vehicles lack stability, leading to potential damage and reduced detection accuracy due to vibrations and obstructions.
Innovation Solution
A mounting structure that secures the vicinity information detection sensor to the apron upper member, either directly or via a bracket, with the detection unit oriented towards the vehicle's outer side, and optionally mounted between the apron upper member and fender panel, to enhance stability and reduce obstruction, while also utilizing a ventilation channel for cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the vicinity information detection sensor is mounted to an exterior panel or low-stiffness member, then the mounting structure is simple, but the sensor stability deteriorates due to vibrations during running
Solution Approach 1:
The patent introduces a bracket as an intermediary component between the sensor and the apron upper member. This bracket serves as a mediator that provides a stable mounting interface, isolating the sensor from vibrations transmitted through the exterior panel while maintaining a relatively simple overall mounting structure.
Solution Approach 2:
The patent specifies that the apron upper member should have a closed cross-sectional structure, which provides inherent structural rigidity and vibration resistance. This structural curvature/closure principle enhances the stiffness of the mounting base without significantly increasing complexity.
2Device complexity
If the detection unit is positioned closer to the vehicle body, then the mounting structure is simpler, but detection accuracy deteriorates due to obstruction by surrounding components
Solution Approach 1:
The patent positions the detection unit to protrude from the vehicle body in the vehicle width direction, utilizing the spatial dimension between the apron upper member and fender panel. This dimensional arrangement allows the detection unit to extend outward for better detection coverage while still being structurally supported by the closed cross-sectional apron member.
3Device complexity
If the sensor is mounted without additional support structures, then the mounting structure is simple, but the sensor is vulnerable to damage during collisions
Solution Approach 1:
The patent utilizes the closed cross-sectional structure of the apron upper member as a protective framework that absorbs and distributes collision forces before they reach the sensor. This structural design provides beforehand protection against lateral collisions, reducing the risk of sensor damage during vehicle operation.
