HINGED VEHICLE DOOR OPERATING MECHANISM HAVING MULTIPLE SLIDES FOR INCREASING TORQUE DURING OPERATION

摘要

A vehicle door assembly includes a vehicle door having a door cavity defined between outer and inner panels. The door is rotationally operable about a door hinge. A first slide is coupled to the vehicle door. A rotating bar is slidably coupled to the first slide and is operable about a bar hinge between door-closed and door-open positions. The bar hinge is coupled to the vehicle frame and is distal from the door hinge. An actuator includes a drive portion coupled to a drive mechanism that rotates the actuator about a drive shaft and an idler portion rotationally coupled to the drive portion at an actuator pivot. Operation of the drive portion slidably operates an actuator end along a second slide defined by the rotating bar between a high-torque position that corresponds to the door-closed position and a low-torque position that corresponds to the door-open position.

1. A vehicle door assembly comprising:
a vehicle door having an outer panel and an inner panel, wherein a door cavity is defined between the outer and inner panels, and wherein the vehicle door is rotationally operable about a door hinge coupled to a vehicle frame; a first slide coupled to a portion of the vehicle door; a rotating bar slidably coupled at a first bar end to the first slide between a plurality of first slide positions and operable at a second bar end about a bar hinge between door-closed and door-open positions, wherein the bar hinge is coupled to the vehicle frame and positioned distal from the door hinge; a second slide at least partially defined by the rotating bar; and an actuator having a drive portion coupled to a drive mechanism that rotates the actuator about a drive shaft, wherein the actuator also includes an idler portion rotationally coupled to the drive portion at an actuator pivot, wherein operation of the drive portion slidably operates an actuator end along the second slide between a high-torque position that corresponds to the door-closed position of the rotating bar and a low-torque position that corresponds to the door-open position of the rotating bar.
