Abstract

In certain example embodiments of this invention, there is provided a grille for a vehicle (e.g., a car, truck, SUV, or the like). In certain example embodiments, the vehicle grille includes adjustable louvers. In certain example embodiments, the louvers are configured to change position relative to the grille (e.g., to rotate, slide, or otherwise move) when a predetermined condition is met (e.g., vehicle speed above/below a predefined threshold, wind speed above/below a predefined threshold, etc.). This configuration advantageously may result in better vehicle performance (such as, for example, better fuel efficiency), e.g., related to less drag and/or improved aerodynamics.

Claims

1. A grille for a vehicle, comprising:

at least one decorative opening; and

at least one adjustable louver integrated into the grille on an interior side thereof, the at least one adjustable louver being configured to rotate and/or slide between at least first and second positions when a predetermined condition is met or not met,

wherein the first position is an open position, and

wherein the second position is a closed position that at least partially closes the at least one decorative opening.

2. The grille of claim 1, wherein the at least one louver is made of a glass-filled polypropylene or nylon.

3. The grille of claim 1, wherein the at least one louver is co-extruded with an inner member of the grille.

4. The grille of claim 1, further comprising sealant material provided to the at least one louver that helps for a seal between features of the grille and the at least one louver when the at least one louver is in the closed position.

5. The grille of claim 4, wherein the sealant material is a thermoplastic elastomer.

6. The grille of claim 1, wherein the at least one louver is arranged so as to rotate about a pivot location located on an interior side of the grille in moving between the at least first and second positions.

7. The grille of claim 6, wherein the at least one louver is substantially parallel to the ground in the first position and substantially perpendicular to the ground in the second position.

9. The grille of claim 1, wherein the predetermined condition corresponds to a wind noise threshold.

10. The grille of claim 1, wherein the predetermined condition corresponds to a speed threshold.

11. The grille of claim 1, wherein the at least one louver is configured to rotate and/or slide between a third position between the first and second positions when a second predetermined condition is met or not met.

8. The grille of claim 8, wherein the pivot location is located in the approximate center of the height of the at least one decorative opening.

12. A vehicle including a grille, the grille comprising:

at least one decorative opening; and

at least one adjustable louver integrated into the grille on an interior side thereof, the at least one adjustable louver being configured to rotate and/or slide between a plurality of discrete positions when predetermined conditions are met or not met,

wherein a first position in the plurality of discrete positions is an open position, and

wherein a second position in the plurality of discrete positions is a closed position that at least partially closes the at least one decorative opening.

13. The vehicle of claim 12, further comprising a sensor configured to gather data associated with the predetermined conditions.

14. The vehicle of claim 13, wherein the sensor is configured to gather data pertaining to wind noise.

15. The vehicle of claim 13, wherein the sensor is configured to gather data pertaining to vehicle speed.

16. The vehicle of claim 13, further comprising a mechanical actuator configured to cause the at least one louver to change positions based on data gathered by the sensor.

17. The vehicle of claim 12, further comprising sealant material provided to the at least one louver that helps for a seal between features of the grille and the at least one louver when the at least one louver is in the closed position.

18. The vehicle of claim 12, wherein the at least one louver is arranged so as to rotate about a pivot location located on an interior side of the grille in moving between the at least first and second positions.

19. A method of making a grille for a vehicle, the method comprising:

providing the grille; and

integrating at least one adjustable louver into the grille on an interior side thereof, the at least one adjustable louver being configured to rotate and/or slide between at least first and second positions when a predetermined condition is met or not met,

wherein the first position is an open position, and

wherein the second position is a closed position that at least partially closes the at least one decorative opening.

20. The method of claim 19, wherein the grille comprises an inner member and an outer member, and further comprising co-extruding the at least one louver with the inner member of the grille.
