Detachable Jack-Up Cover for EV Underbody Aerodynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing under-vehicle covers for electric vehicles face challenges in maintaining aerodynamic performance when using jack-up flanges or separate jack-up pads, as these configurations often compromise the structural integrity and aerodynamic benefits of the cover.
Innovation Solution
A detachable jack-up cover designed for electric vehicles, which is fastened to the under-vehicle cover and covers the lower portion of the jack-up flange. This cover includes a lower cover part, a side cover part, and an upper cover part, with fastening and clip parts to secure it in place, allowing for various layouts and ensuring aerodynamic performance regardless of the jack-up method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate jack-up pad or jack-up flange is used to enable vehicle lifting, then the jack-up function is achieved, but the aerodynamic performance of the under-vehicle cover deteriorates
Solution Approach 1:
The patent merges the jack-up flange structure with the under-vehicle cover by forming the jack-up flange directly on the cover surface. The cover includes a recessed portion that houses the jack-up flange, integrating two previously separate functions (aerodynamic covering and vehicle lifting) into a single unified structure, thereby maintaining aerodynamic performance while enabling jack-up operation
Solution Approach 2:
The under-vehicle cover is designed to serve multiple functions simultaneously: it provides aerodynamic protection, houses the jack-up flange for vehicle lifting, and includes a recessed portion that accommodates both functions. This multi-functional design eliminates the need for separate jack-up pads while preserving aerodynamic efficiency
2Reliability
If the under-vehicle cover is designed to cover the jack-up flange, then aerodynamic performance is improved, but the jack-up operation becomes difficult
Solution Approach 1:
The cover structure is segmented into different functional zones: a main covering portion for aerodynamic protection and a recessed portion for housing the jack-up flange. This segmentation allows the cover to provide continuous aerodynamic coverage while creating a dedicated access area that facilitates jack-up operation without compromising overall aerodynamic performance
3Ease of operation
If molding parts are separated to apply a separate jack-up pad, then jack-up function is achieved, but aerodynamic performance deteriorates
Solution Approach 1:
Instead of separating molding parts to add a jack-up pad, the patent combines the jack-up flange function directly into the cover structure. The recessed portion of the cover houses the jack-up flange, merging the aerodynamic cover and jack-up mechanisms into a single integrated component, thereby eliminating the need for separate pads and maintaining aerodynamic continuity
