An automatic door opening and closing device include a housing which may contain a control unit. A motor may be in electronic communication with the control unit, and a wheel may be coupled to the motor so that the motor may be operable to rotate the wheel in a clockwise direction and in a counter clockwise direction. A chassis may be configured to couple the motor to a door so that the wheel is in contact with a ground surface below the door. The motor may be operable to rotate the wheel clockwise across the ground surface to motivate the door in a first direction, and the motor may be operable to rotate the wheel counterclockwise across the ground surface to motivate the door in a second direction. By motivating the door in either the first direction or the second direction, the device may be configured to move the door into, out of, and between the open and closed positions.

A power swing door drive actuator for moving a passenger swing door relative to a body portion of a motor vehicle. The power swing door actuator includes a housing, a motor operably mounted to the housing, and a leadscrew of a spindle drive mechanism rotatably driven by the motor for causing relative translational movement of a drive nut relative to the leadscrew which, in turn, results in the vehicle door swinging between open and closed positions in response to selective actuation of the motor. A first articulation joint unit couples an elongate extensible member fixed to the drive nut to the vehicle body while a second articulation joint unit couples the housing to the vehicle door.
