ACTIVE AERODYNAMICS LIFTGATE SPOILER DESIGN WITH MULTI 4 BAR KINEMATIC LINKAGES

摘要

An active liftgate spoiler (10;100;200;300;400) used on a liftgate (8) of a vehicle (6). The liftgate has an upper surface (4) and is typically a rear liftgate or hatch on the rear side of the vehicle. A housing (11;104;202;302;412) is connected to the upper surface of the liftgate. There is a moveable panel ( 12; 102;204, 208; 306, 308;402,403) connected to the housing using a connection. The connection is formed by a four bar linkage (20,20'; 106, 106';210,210'; 311,311 ';411, 411') that forms a portion of the connection between the moveable panel and the housing. An actuator (14;110;212;314;414), which in one embodiment is a single rotary actuator is connected to the four bar linkage and causes the movement of the moveable panel.
