Power swing door actuator with integrated door check mechanism
First Claim
1. A door check mechanism for a vehicle door moveable relative to a vehicle body between a closed position and a fully-open open position, the door check mechanism comprising:
- a housing connected to the vehicle door and having a linearly moveable actuation member driven by an electric motor; and
an articulating linkage pivotably interconnecting the actuation member to the vehicle body; and
a door check device operably associated with the linkage for mechanically holding the vehicle door in at least one intermediate open position in addition to the fully-open position, wherein the door check device is configured to apply a compressive load to the linkage, wherein the compressive load exerted on the linkage holds the door in the at least one intermediate position, wherein the door is held without actuation of the electric motor,wherein linear movement of the actuation member in a first direction causes movement of the vehicle door in an opening direction from the closed position toward the fully-open position and linear movement of the actuation member in a second direction causes movement of the vehicle door in a closing direction toward the closed position;
wherein the actuation member includes a spindle drive mechanism including a leadscrew supported for rotation in the housing, and a drive nut in threaded engagement with the leadscrew, the drive nut having a pivot post;
wherein the articulating linkage is connected to the drive nut.

Abstract
A power swing door actuator for moving a passenger swing door relative to a body portion of a motor vehicle. The power swing door actuator includes a housing rigidly fixed to the swing door, a motor mounted to the housing, a connector link having a first end pivotably coupled to the vehicle body portion and a second end pivotably coupled to a drive nut of a spindle drive mechanism. A leadscrew of the spindle drive mechanism is rotatably driven by the motor for causing relative translational movement between the drive nut and the leadscrew which, in turn, results in pivoting movement of the connector link while the vehicle door swings between open and closed positions in response to selective actuation of the motor. The power swing door actuator is further equipped with an integrated door check mechanism.

14. A door check mechanism for a vehicle door moveable relative to a vehicle body between a closed position and a fully-open position, the door check mechanism comprising:
-
a housing fixedly connected to the vehicle door; an electric motor supported by the housing; a drive member supported for linear movement relative to the housing and driven by the electric motor; a connector link having a first link segment pivotably connected to the drive member and a second link segment pivotably connected to the vehicle body; and a door check device operably disposed between the connector link and the vehicle door for mechanically holding the door in at least one intermediate open position in addition to the fully open position, wherein the door check device is configured to apply a compressive load to the connector link, wherein the compressive load exerted on the connector link holds the door in the at least one intermediate position, wherein the door is held without actuation of the electric motor, wherein linear movement of the drive member in a first direction forcibly drives the housing in a first direction to move the vehicle door in an opening direction from the closed position toward the fully-open position and linear movement of the drive member in a second direction forcibly drives the housing in a second direction to move the vehicle door in a closing direction toward the closed position; wherein the drive member includes a lead screw and a drive nut in threaded engagement with the lead screw, the drive nut having a pivot post, wherein the drive nut is connected to the connector link. - View Dependent Claims (15, 16, 17, 18, 19)

20. A door check mechanism for a power swing door that is moveable relative to a vehicle body between a closed position and a fully-open position, the door check mechanism comprising:
-
a housing fixedly connected to the vehicle door and defining a guide channel having at least one detent; an electric motor supported by the housing; a spindle drive mechanism including a leadscrew supported for rotation in the housing and driven by the electric motor, and a drive nut in threaded engagement with the leadscrew, the drive nut having a pivot post; an elongated connector link having a first link segment pivotably connected to the pivot post on the drive nut and a second link segment pivotably connected to the vehicle body; and a door check device disposed between the housing and one of the drive nut and the first link segment of the connector link for mechanically holding the vehicle door in at least one intermediate open position in addition to the fully-open position, the door check device including a spring-loaded follower mounted on the pivot post and being retained in the guide channel and operable to engage the at least one detent thereon so as to hold the vehicle door in at least one intermediate open position.
