Angled active shutter with dual-drive actuation
First Claim
1. A shutter system comprising:
- a first louver configured to rotate about a first pivot axis;
a second louver configured to rotate about a second pivot axis, wherein the second pivot axis intersects the first axis and is arranged at an angle that is smaller than 180 degrees and larger than zero degrees with respect to the first pivot axis; and
a dual-drive actuation mechanism configured to rotate the first and the second louvers about the respective pivot axes, the mechanism including;
a first driven element operatively connected to the first louver;
a second driven element operatively connected to the second louver; and
a drive element configured to receive a drive torque and apply the drive torque simultaneously to the first and second driven elements, wherein;
the first driven element includes a first gear,the second driven element includes a second gear, andthe drive element includes a first toothed portion engaged with the first gear anda second toothed portion engaged with the second gear, and wherein;
each of the first and second toothed portions includes one of a spherical and a conical profile andeach of the first and second gears includes a corresponding one of a conical and a spherical profile.

Abstract
A shutter system includes a first louver configured to rotate about a first pivot axis and a second louver configured to rotate about a second pivot axis. The second pivot axis is arranged at an angle that is smaller than 180 degrees with respect to the first pivot axis. The shutter system also includes a dual-drive actuation mechanism configured to rotate the first and the second louvers about the respective pivot axes. The dual-drive mechanism includes a first driven element operatively connected to the first louver and a second driven element operatively connected to the second louver. The dual-drive mechanism also includes a drive element configured to receive a drive torque and apply the drive torque simultaneously to the first and second driven elements. A vehicle having the above shutter system is also disclosed.
