Power door with toothed rod crank mechanism

Abstract

A power swing door actuator configured for use in a power door actuation system in a motor vehicle having a vehicle door pivotably connected to a vehicle body for movement along a swing path between open and closed positions is provided. The power swing door actuator includes a power-operated drive mechanism connected to the vehicle door with a rotary driven member configured for rotation in response to selective actuation of the power-operated drive mechanism. An elongate rack pivotably connected to the vehicle body and the rotary driven member is maintained in engagement with the rack via aretention member. Rotational movement of the rotary driven member in a first direction causes the vehicle door to move in an opening direction, while rotational movement of the rotary driven member ina second direction causes the vehicle door to move in a closing direction.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application Serial No. 62 / 573,858, filed October 18, 2017, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to power door systems for motor vehicles, and more particularly, to power door actuators operable for swinging a door between an open position and a closed position in a pivotal relationship relative to a vehicle body. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] Passenger doors on motor vehicles are typically mounted to the vehicle body by upper and lower door hinges for swinging movement about a generally vertical pivot axis. Each door hinge generally includes a door hinge strap connected to the passenger door, a body hinge strap connected to the body, and a pivot pin confi...

AI Technical Summary

Problems solved by technology

Problems with such swinging passenger doors ("swing doors") have been recognized, such as when the vehicle is on an inclined surface and the swinging door opens too far or swings closed due to the unbalanced weight of the door.

As such, the power door actuation systems described above are generally not intended for use in applications other than the intended custom vehicle application

Furthermore, these custom integrated power door actuation systems are complex and relatively expensive, and thus are typically reserved for higher end vehicle platforms where cost is generally less of a consumer concern
