Vehicle Radar Mounting Structure for Water and Vibration Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radar device mounting structures on vehicles protrude below the lamp chamber, limiting layout flexibility, detection accuracy, and ease of maintenance, while exposing the device to water and vibration.
Innovation Solution
A mounting structure that includes a cover member with ribs extending from the cover member, supporting the radar device and providing protection from water and vibration, with a simple configuration that enhances positioning accuracy and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the radar device is disposed protruding below the lamp chamber, then the mounting structure is simple, but the detection accuracy is limited and the device is exposed to water and vibrations
Solution Approach 1:
The patent transitions from a protruding mounting configuration to a flush-mounted configuration by utilizing the lamp chamber cavity space. The radar device is positioned within the lamp chamber at the same level as the headlight lens, effectively using the third dimension (depth) to resolve the contradiction between simple mounting and accurate detection.
Solution Approach 2:
The radar device is nested within the lamp chamber housing structure. The cover member with integrated ribs provides a housing that contains the radar device, allowing it to be protected and positioned within the existing headlight assembly without protruding, thus achieving both simplicity and protection.
2Ease of manufacture
If the radar device protrudes below the lamp chamber, then installation is straightforward, but maintenance access is difficult and time-consuming
Solution Approach 1:
The mounting structure is segmented into modular components: the cover member with ribs, the mounting ribs themselves, and the radar device. This segmentation allows the radar device to be independently accessed by removing the cover member, facilitating easy maintenance while maintaining a compact integrated appearance during operation.
Solution Approach 2:
The cover member acts as an intermediary element that provides easy access to the radar device. By designing the cover member to be removable or accessible, it mediates between the need for a compact mounted appearance and the need for easy maintenance access, allowing technicians to access the radar device without disassembling the entire headlight assembly.
3Device complexity
If the radar device is exposed without a cover, then the configuration is simple, but the device is vulnerable to water and vibrations reducing durability
Solution Approach 1:
The cover member is merged with the mounting structure, combining the protective cover function with the mounting function into a single integrated component. The ribs of the cover member serve dual purposes: providing structural support for mounting the radar device and forming a protective enclosure, thus achieving protection without significant complexity increase.
Solution Approach 2:
The cover member performs multiple functions simultaneously: it protects the radar device from water and vibrations, provides a mounting surface via integrated ribs, and maintains the aesthetic appearance of the headlight assembly. This multi-functionality resolves the contradiction between simplicity and durability by combining several functions into one component.

AI summary
The disclosure provides a mounting structure of an object detection device to a vehicle body capable of improving the accuracy of object detection by the object detection device and improving the durability of the object detection device. A mounting structure of a radar device, which is an object detection device for detecting objects, to a vehicle body, includes a cover member attached to the vehicle body side and covering at least a part of the radar device. The cover member is disposed on a first direction side, which is an object detection direction by the radar device when viewed from the radar device. The cover member includes a rib extending from the cover member in a second direction opposite to the first direction. The radar device is fixed to the rib.
