Vehicle Outside Sensor Unit Slant Angle Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle outside sensor units face challenges in adjusting the slant angle in the vehicle roll direction without complicating the sensor's structure, which can increase product costs and affect detection accuracy.
Innovation Solution
A vehicle outside sensor unit configuration that includes a main bracket, a support bracket, a rotation device with a rotation axis parallel to the vehicle's roll axis, and a position adjustment device, allowing for the adjustment of the slant angle by rotating the support bracket relative to the main bracket, thereby simplifying the sensor's structure while ensuring accurate detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a mechanism that adjusts the slant angle in the vehicle roll direction of the detection surface is provided, then the detection accuracy of the outside sensor is improved, but the structure of the outside sensor becomes complicated and product costs increase
Solution Approach 1:
The bracket is divided into a main bracket and a support bracket that can rotate relative to each other. The outside sensor is mounted on the support bracket, which is rotatably connected to the main bracket via a rotation device. This segmentation allows the detection surface to be independently adjusted without complicating the overall structure.
Solution Approach 2:
The support bracket is designed to be rotatable relative to the main bracket around a rotation axis line that is substantially parallel to the vehicle roll axis. A position adjustment device enables dynamic adjustment of the relative rotation position, allowing the slant angle of the detection surface to be adjusted while maintaining a simple structure.
2Device complexity
If the rotation device is positioned in the outside detection direction of the outside sensor, then the structure is simplified, but the outside detection range of the outside sensor is reduced
Solution Approach 1:
The rotation device is extracted from the detection direction and positioned at the rear side of the outside sensor. The rotation axis line is arranged so that it does not interfere with the detection path, allowing the outside sensor to maintain a wide detection range while the rotation device remains structurally simple.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for precise adjustment of the slant angle in the vehicle roll direction without complicating the sensor's structure, enhancing detection accuracy and maintaining a wide detection range while keeping the sensor's design simple and cost-effective.
Implementation Method 1
a male screw member that is provided on any one of the support bracket and the main bracket at a position which is separated from the rotation axis line and a female screw member that is provided on the other of the support bracket and the main bracket at a position which is separated from the rotation axis line and that is screwed to the male screw member

AI summary
An outside sensor unit includes an outside sensor, a main bracket, a support bracket, a rotation device, and a position adjustment device. The outside sensor detects the outside of a vehicle. The main bracket is attached to a vehicle body. The support bracket supports the outside sensor and is attached to the main bracket. The rotation device has a rotation axis line which is substantially parallel to a roll axis of the vehicle and connects the support bracket and the main bracket together rotatably around the rotation axis line. The position adjustment device is capable of adjusting the relative rotation position between the support bracket and the main bracket around the rotation axis line.
