Active Front Deflector Cover Structure Against Foreign Matter Ingress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing active front deflectors face challenges in suppressing the ingression of foreign matter between the deflector body and the support body, particularly due to the design of the actuator and link mechanism.
Innovation Solution
A deflector device with a cover portion that covers the divide between the deflector body and the support body, restricting rotation and preventing foreign matter ingress, and incorporating a rotation portion that fits together with the cover portion to enhance suppression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the deflector body is rotatably supported by the support body to enable deployment and stowage, then the deflector device can suppress airflow onto the front wheel, but foreign matter can ingress between the deflector body and support body
Solution Approach 1:
A cover portion is introduced as an intermediary component between the deflector body and support body. This cover portion rotates together with the deflector body and covers the divide between them, preventing foreign matter from entering the rotational mechanism while allowing the deflector to deploy and stowage
2Object-affected harmful factors
If the cover portion is added to prevent foreign matter ingress, then foreign matter ingression is suppressed, but the device complexity increases
Solution Approach 1:
The cover portion is merged with the rotation mechanism by making it rotate together with the deflector body as a unified structure. This integration prevents foreign matter ingress without requiring separate complex mechanisms, thereby limiting the increase in device complexity

AI summary
In a deflector device, a deflector body is rotated with respect to a case. A restriction plate of the case covers a divide between the deflector body and the case. Foreign matter is accordingly suppressed from ingression between the deflector body and the case by the restriction plate.
