Definitions

  • the present invention relates to a modifiable active grille shutter which can be used in a multitude of vehicles.
  • Active front grille structures have been used in recent vehicles to provide improved aerodynamics to vehicles and also provide improved modulation of airflow to the vehicles’ cooling system. This provides for efficiencies which add to the vehicle’s range and performance.
  • active grille structures include a series of moveable vanes which move in response to vehicle controls to open or close a series of vanes on the grille. Examples of such structures are found in co-assigned U.S. patent nos. 9,694,669, 10,766,356, and 11 ,065,952. Typically, such structures are vehicle program-specific and designed for use in a particular vehicle trim level. Therefore, such structures do not have cross-platform applicability and are somewhat costly to produce.
  • the structure includes A center framing common portion which includes a modular vane structure that can be removed and substituted for another structure.
  • At least one outer peripheral attachable active air frame valance is selectively attachable on the sides of the frame.
  • the modular vane structure has a 3-dimensional appearance formed by compression injection molding of a clear polycarbonate.
  • the clear polycarbonate is coated on the back side thereof to provide an opaque vane structure with a textured appearance but having a sooth outer face for sealing purposes.
  • FIG. 1 is a rear view of a grille made in accordance with the teachings of the present invention.
  • Figure 2a is the view of Figure 2 illustrating the common frame used in the grille along with a first alternative side frame valance made in accordance with the teachings of the present invention
  • Figure 2b is the view of Figure 2 illustrating the common frame used in the grille along with a second alternative side frame valance made in accordance with the teachings of the present invention
  • Figure 3 is a view similar to Figure 1 highlighting the common area of the present invention
  • Figure 3a is the view of Figure 2 illustrating the common frame used in the grille along with a first alternative side frame valance made in accordance with the teachings of the present invention
  • Figure 3b is the view of Figure 2 illustrating the common frame used in the grille along with a second alternative side frame valance made in accordance with the teachings of the present invention
  • Figure 4 is a side sectional view of a moveable vane of the present invention showing the paint film coating on the rear surface of the vane;
  • Figure 5 is a side sectional view of a moveable vane of the present invention showing the paint film coating on the rear surface of the vane;
  • the structure 10 includes a center framing common portion 12 which includes a modular vane structure insert 14 that can be removed and substituted for another structure. At least one outer peripheral attachable active air frame valance 16 is selectively attachable on the sides of the frame 16.
  • the grille structure 10 formed by the modular vane structure has a 3-dimensional appearance 19 formed by compression injection molding of a clear polycarbonate 18.
  • the clear polycarbonate 18 is coated on the back side 20 thereof with a coating 22 to provide an opaque vane structure.
  • the active air frame 12 is selected to match the vehicle it is to be installed in.
  • the modular frame structure insert 14 is selected from a suitable vehicle matching insert containing features such as a moveable door, a textured member, a vertical louver member, a horizontal louver member or an angled louver member. Examples of various final active grilles structures may be employed.
  • the common portion 12 includes an active vane includes a modular frame active grille structure 11 which holds the vanes in a frame 13.
  • the frame includes a motor 15 and an actuator 17 for moving the vane in response to predetermined vehicle operating conditions such as speed, temperature, sensed engine parameters and the like.
  • the combination of the modular vane structure and active air frame is preselected for stylistically matching of the aesthetics of a vehicle.
  • side valances 16 are also selected from appearance matching members 16A or 16B or another design matching the styling required for a particular application and are attached to provide proper appearances for their respective fascia assemblies.
  • the active grille structure includes vanes made of a clear polycarbonate 18.
  • the back 20 of said clear polycarbonate vane 18 is coated with a paint film or other coating 22 to provide a color matching or color-controlled surface.
  • a paint film is preferred other coatings could also be used to provide an opaque blade or a semitransparent blade or a transparent blade.
  • the blade is injection compression molded and the paint film used is at least partially transparent.
  • the outside show surfaces of the blade include a flat-type glare-free surface which can either be formed during molding of the polycarbonate or can be supplied by coating of the polycarbonate with a clear flat paint coating 24.
  • the outer show surface of the vane is formed in a 3-dimensional pattern for forming the final stylistic design of the grille.
  • the partially transparent film allows light to go through the film but appears opaque in the absence of light being transmitted through the film.
  • ICM Injection Compression molding
  • a special clear primer system 26 is available from Magna LexaMar, Michigan U.S that allows for the paint to adhere on the hard-coated surface.
  • the polycarbonate surface after being hard coated with siloxane obtains a glasslike behavior with superior abrasion resistance thus adhesion over this type of surface is very challenging.
  • a paint film is molded in place to create textures on the front or back of the vanes, the common framing or the end valances 16A, 16B.
  • the film can be attached to the vanes or outer structure to simulate a 3-dimensional surface to the part.
  • a show surface can be presented on the part via a paint layer.

Abstract

L'invention concerne une structure de grille active. La structure comprend une partie commune d'encadrement centrale qui comprend une structure d'aube modulaire qui peut être retirée et remplacée par une autre structure. Au moins une jupe de cadre d'air actif pouvant être fixé à un périphérique externe peut être fixée de manière sélective sur les côtés du cadre pour correspondre à l'aspect d'un véhicule prédéterminé. Ainsi, la structure d'aube modulaire a un aspect tridimensionnel formé par moulage par injection et compression d'un polycarbonate transparent. Les composants de polycarbonate transparent sont revêtus sur le côté arrière de ceux-ci pour fournir l'aspect souhaité à travers les jupes de cadre, les aubes et la partie centrale.
