Segmented Vehicle Undercover for Moisture Protection and Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle undercover structures fail to adequately protect electric/electronic components from moisture ingress, leading to potential electric short circuits and do not maintain sufficient ground clearance for moving components, compromising vehicle operation.
Innovation Solution
A vehicle undercover structure comprising a main undercover supported by cross plates and mounting brackets, with an auxiliary undercover, designed to cover and protect moving components, ensuring watertightness and electrical safety by preventing moisture entry and maintaining clearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the undercover is not disposed under the lateral rod moving upwards and downwards between the pair of side rails, then it is highly likely for moisture to enter the connectors of the electric/electronic components adjacent to the lateral rod, but disposing the undercover there may interfere with the moving component's operation
Solution Approach 1:
The undercover is divided into a first undercover and a second undercover. The first undercover is disposed under the lateral rod to protect connectors from moisture, while the second undercover is disposed at the lower side of the lateral rod to avoid interfering with its movement. This segmentation allows each undercover to serve its specific protective function without obstructing the lateral rod's operation.
Solution Approach 2:
Different regions of the vehicle frame are provided with different undercover configurations tailored to local requirements. The first undercover is specifically positioned under the lateral rod where connector protection is critical, while the second undercover is positioned elsewhere to provide additional protection without interfering with moving components. This local differentiation optimizes both protection and operational freedom.
2Reliability
If the undercover is lower than a lower limit position of the moving component which is movable upwards and downwards, then ground clearance for obstacle avoidance may be compromised, but raising the undercover may reduce protection effectiveness
Solution Approach 1:
The undercover system is segmented into multiple components (first undercover, second undercover) that can be positioned at different heights and locations. This allows the first undercover to be raised to protect connectors effectively, while the overall undercover structure maintains sufficient ground clearance through the strategic positioning of the second undercover and other components.
Solution Approach 2:
The protection strategy moves from a single low-positioned undercover to a multi-level three-dimensional arrangement. The first undercover is positioned higher to protect connectors, while the second undercover and other components provide additional protection at different levels, creating a distributed protection system that maintains ground clearance while improving protection effectiveness.

AI summary
A vehicle undercover structure, includes a vehicle body frame including a first side rail and a second side rail spaced from each other in a width direction of a vehicle; a front undercover mounted on the front of the vehicle body frame; a rear undercover mounted on the rear of the vehicle body frame; and a main undercover disposed between the front undercover and the rear undercover, wherein the main undercover covers a moving component which is movable between an upper limit position and a lower limit position on the vehicle body frame.
