  • Motor driven air vent device for vehicle
    Patent number: 11225126
    Abstract: A motor driven air vent device for a vehicle can perform not only left/right angular rotation operation of a vertical wing for adjusting a left/right-directional airflow direction of air discharged indoors but also an opening/closing operation of a damper for interrupting or allowing an indoor discharge of air using a link bar for performing a straight line motion to the left or right thereof by driving a motor and a cam plate for angularly rotating by the link bar, etc. in a motor driven manner.

  • Motor-driven air vent device for vehicle
    Patent number: 11065939
    Abstract: A motor-driven air vent device for a vehicle is provided. The motor-driven air vent device connects a horizontal wing of an air vent to an output shaft of a driving motor through a link structure and rotatably operates the driving motor in the forward direction or the reverse direction by a touch type switch operation. Accordingly, the vertical angular rotation operation for the horizontal wing is automatically performed by the operation of the link structure delivering the torque of the driving motor.
