Abstract: A variable grille apparatus adjusts the flow rate of air flowing through a grille. Commercial value of a vehicle is improved by enhanced opening and closing motions when adjusting the flow rate of air. Further, since the grille is opened and closed in various ways such as by sequential or simultaneous opening and closing, the opening and closing motions of the grille are enhanced, the external design is diversified, and a flow rate of air is secured through structurally optimal arrangement.

Abstract: The present invention provides a variable aerodynamic system for a vehicle. The system includes an active air skirt, an active rear spoiler, and an active rear bumper spoiler of which one or more are selected and deployed by a controller, while a vehicle is running, when the controller receives information obtained by a detector, and determines that the obtained information satisfies conditions inputted in advance by comparing the obtained information with the conditions inputted in advance. The height from an end of a front bumper to a front wheel center is within a predetermined value.

Abstract: Disclosed is a variable spoiler apparatus of the rear bumper for vehicles. The variable spoiler apparatus includes a linkage device, installed on a bumper back beam, and varies in length in an up-down direction during a rotation. A spoiler is coupled to the linkage device and is able to move in the up-down direction by the rotation of the linkage device. A first drive device is installed on the bumper back beam. The first drive device is provided with a first rotating shaft coupled to the linkage device to transmit rotating force. A guide is rotatably installed on the bumper back beam and is able to extend in the up-down direction. A second drive device is coupled to the guide so as to be movable in the up-down direction. When the second drive device is operated, the spoiler is tilted by a length variation operation of the length-variable unit.
