AI Technical Summary

Problems solved by technology

[0007] Existing liftgate spoilers are mostly static and must satisfy both stop and go requirements and a single balance between styling and performance
Spoiler surface movement is limited due to packaging constraints
On surfaces where active spoilers are used, the spoiler typically uses linear actuators to articulate the surface, but due to the liftgate geometry and motion, the required packaging space is often limited

Embodiment approach

[0023] Referring now to the accompanying drawings, figure 1 , Figure 1A and Figure 1B A first embodiment of the present invention is shown, including a top perspective view of an active liftgate spoiler 10 having a Sliding lower panel 12 . The active liftgate spoiler 10 is connected to or forms part of the liftgate 8 of the vehicle 6 . More specifically, an active liftgate spoiler 10 is attached or formed at the upper surface 4 of the liftgate 8 . The vehicle 6 has a longitudinal axis A, relative to which the different movable parts of the invention move. Although the upper surface 4, the vehicle 6 and the active liftgate spoiler 10 are only in Figure 1A and Figure 1B shown in , but it is understood that all other liftgate spoilers described in other embodiments of the invention are used in conjunction with Figure 1A and Figure 1B Attached to or formed with a liftgate used on a vehicle at the same location as shown in .

Abstract

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.
