Variable or stepped louver activation for active grille system

摘要

An active grille system which is mounted to a fascia, grille, or carrier, or is part of the carrier of an automobile. Two sets of louvers are rotatably mounted to a frame, and a camming mechanism provides selective actuation of both sets of louvers, and an actuator controls the camming mechanism such that the actuator moves the camming mechanism between a first position, a second position, and a third position. When the camming mechanism is in the first position, both the first set and second set of louvers are in a closed position, when the camming mechanism is in the second position, the first set of louvers are in an open position and the second set of louvers are in a closed position, and when the camming mechanism is in the third position both the first set and second set of louvers are in an open position.

主权项

1. An active grille system, comprising:
a frame; a first set of at least one louver rotatably mounted to said frame; a second set of at least one louver rotatably mounted to said frame; a camming mechanism including a first camming plate rotatably mounted to a shaft and second camming plate rotatably mounted to the shaft for providing selective actuation of said first set of at least one louver and said second set of at least one louver, wherein said camming mechanism is rotatable between a first position, a second position, and a third position; wherein said first position, said second position and said third position rotate said first set of at least one louver and said second set of at least one louver to an opened position, closed position and intermediate position, each corresponding to said first position, said second position and said third position; a first link pivotally connected to said first set of at least one louver, a second link pivotally connected to said second set of at least one louver; a first slot formed on the first camming plate and a second slot formed on the second camming plate, where the first slot is shaped different from the second slot; and a pin of the first link received in the first slot and a pin of the second link received in the second slot, where in the first slot and the second slot are shaped to move the respective one of the pin of the first link and the pain of the second link separately.
