Vehicle Body Lower Structure Airflow Guiding Plate Hook Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle body lower structures face challenges in achieving optimal aerodynamic performance while ensuring the airflow guiding plate remains properly positioned and secured, preventing over-expansion or detachment.
Innovation Solution
The vehicle body lower structure incorporates a movable airflow guiding plate with a hook member on its upper surface. The hook member is designed to separate from the vehicle body's buckle part when the plate is in the receiving position and lock onto it when in the deploying position, ensuring the plate is securely supported and preventing over-expansion or detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If the airflow guiding plate is designed to be movable between receiving position and deploying position to improve aerodynamic performance, then the aerodynamic performance is improved, but the risk of the plate being over-expanded or detached increases
Solution Approach 1:
The airflow guiding plate is designed as a movable component that can dynamically adjust between a receiving position (covering the lower part of the vehicle body) and a deploying position (protruding downward). This dynamic configuration allows the plate to adapt to different operational requirements, improving aerodynamic performance when deployed while maintaining vehicle body coverage when in the receiving position.
Solution Approach 2:
The plate assembly is segmented into multiple functional components: the airflow guiding plate itself, the hook member for securing, and the buckle part for engagement. This segmentation allows independent optimization of each component's function while maintaining overall system reliability through coordinated operation of the parts.
2Object-generated harmful factors
If the airflow guiding plate is deployed to protrude downward for better airflow guidance, then aerodynamic performance improves, but the plate may become over-expanded or detached from the vehicle body
Solution Approach 1:
The hook member acts as an intermediary component between the airflow guiding plate and the vehicle body. It provides a reliable connection mechanism that prevents the plate from becoming over-expanded or detached while allowing the plate to be deployed for improved aerodynamic performance. The hook member mediates the interaction between the movable plate and the fixed vehicle body structure.
3Object-generated harmful factors
If a movable airflow guiding plate is installed to enhance aerodynamics, then aerodynamic performance improves, but the structural complexity of the vehicle body lower structure increases
Solution Approach 1:
The airflow guiding plate is designed with self-service characteristics through the hook member and buckle part mechanism. The plate can be deployed and secured without requiring complex external control systems or additional actuation mechanisms, thereby improving aerodynamic performance while minimizing the increase in structural complexity.

AI summary
The disclosure provides a vehicle body lower structure, which may improve aerodynamic performance and inhibit the airflow guiding plate from being over-expanded or detached. The vehicle body lower structure includes an airflow guiding plate that is arranged on the vehicle body of a vehicle and is movable between a receiving position covering the lower part of the vehicle body and a deploying position protruding downward. The vehicle body lower structure further includes: a hook member, which is provided on the upper surface of the airflow guiding plate. When the airflow guiding plate is in the deploying position, the hook member is locked onto the buckle part of the vehicle body. When the airflow guiding plate is located at the receiving position, the hook member is separated from the buckle part of the vehicle body.
