Benefits of technology

The present invention provides an active grill shutter system for a vehicle that is aerodynamic and minimizes pressure drop when vanes are fully open, while also resistant to air leakage and blow-by when vanes are fully closed. The system has aerodynamically shaped vanes that are rigid and have physical properties sufficient to avoid undesired bending and distortion under a wide range of operating conditions encountered by modern vehicles. The system also provides an effective air block when vanes are closed and minimal pressure drop when fully open, as well as being resistant to freezing, mud and dirt, damage from object impacts, and providing a strong seal against air leakage and blow-by when vanes are fully closed.

Problems solved by technology

Due to conflicting design requirements, the details of any such system are not clear.

Embodiment Construction

[0021]It is to be understood that the present invention is not limited to the particular embodiments of the invention described below, as variations of the particular embodiments may be made and still fall within the scope of the appended claims. It is also to be understood that the terminology employed is for the purpose of describing particular embodiments, and is not intended to be unnecessarily limiting. Where a range of values is provided, it is understood that each intervening value is encompassed within the invention, including upper and lower limits, unless otherwise stated.

[0022]The present invention is generally directed toward an aerodynamically enhanced active grill shutter apparatus 100 (also called an “assembly” or “system” herein) with improved aerodynamically designed vanes for use in connection with a vehicle, typically a passenger or commercial vehicle such as a car or truck. In the present innovation, a cross-sectional profile of the vanes has been developed so th...

Abstract

An integrated assembly includes a vehicle bumper system, and upper and lower air shutter sections with subassembled shutter vanes movable between closed and open positions, an actuator mechanism for moving the shutter members between positions. When in the fully open position, the shutter vanes are aerodynamically designed to minimize air drag, both as air flows past the vanes and also during after-vane airflow (and during after-bumper-beam airflow). When in the fully closed vane position, the vanes seal against each other to provide a highly efficient and leak-resistant air-blocking assembly.

Description

[0001]This application claims benefit under 35 USC §119(e) of provisional application Ser. No. 61 / 603,003, filed Feb. 24, 2012, entitled ACTIVE GRILL SHUTTER VANE DESIGN AND SYSTEM, the entire contents of which are incorporated herein.BACKGROUND[0002]The present invention relates to grill shutter systems for selectively controlling airflow to a vehicle engine / power plant or other vehicle cooled component, and more particularly relates to a shutter system with aerodynamic vanes for low drag pass through when open but also non-leaking air blockage when closed.[0003]Components, such as grills and the like, that affect airflow around a vehicle front end and airflow into a vehicle engine compartment are important for several reasons. For example, the components must provide good airflow for engine cooling, stylistic appearance for customer satisfaction and acceptance, aerodynamic effect for good gas mileage, good impact characteristics (and good repairability) in case of a vehicle crash,...
