Abstract:
1. A deflector for responding a vehicle speed, the deflector comprising: a deflector body that is received in a receiving groove formed in the inside of a door frame and is installed to rotate pivotally toward the rear of the vehicle, wherein one end of the deflector body in the front of the vehicle is coupled via a hinge and the other end of the deflector body in the rear of the vehicle is configured in a form of a free end; a solenoid that is pivotally coupled substantially to the other end of the deflector body and pushes up or down the deflector body; a piezoelectric element that is installed in a division channel and senses the intensity of wind being in contact with the division channel; and an electronic control unit that adjusts a projection height of the deflector body in multiple level by applying control current corresponding to three levels to the solenoid on the basis of the vehicle speed, a status of whether or not a rear door glass is opened, and a sensing signal of the piezoelectric element.
