Extended swing closure member systems for motor vehicles
Exemplary closure member systems for motor vehicles may include one or more power hinge assemblies, non-powered hinge assemblies, or both and are configured to displace a closure member to a fully open position of at least 100 degrees relative to its closed position. The hinge assemblies may embody a multi-axis design for moving the closure member between the closed and fully open positions. The closure member systems may be further configured to move the closure member along different swing paths during an opening sequence and a closing sequence.
1 . A vehicle closure member system, comprising:
a closure member;
a non-powered hinge assembly mounted to the closure member; and
a power hinge assembly mounted to the closure member and adapted to move the closure member between a closed position and a fully open position,
wherein the closure member is displaced by at least 100 degrees from the closed position when moved to the fully open position,
wherein the closure member includes a first swing path when moved from the closed position to the fully open position and includes a second swing path when moved from the fully open position to the closed position, wherein the second swing path is a different swing path than the first swing path.
2 . A vehicle closure member system, comprising:
a closure member;
a non-powered hinge assembly mounted to the closure member; and
a power hinge assembly mounted to the closure member and adapted to move the closure member between a closed position and a fully open position,
wherein the closure member is displaced by at least 100 degrees from the closed position when moved to the fully open position,
wherein the power hinge assembly includes an electric motor, a main link, a drive link, a supporting link, a first mounting plate, and a second mounting plate.
3 . The vehicle closure member system as recited in claim 2 , wherein the electric motor includes a drive shaft configured to rotate about a primary pivot axis to move the drive link along an arced path.
4 . The vehicle closure member system as recited in claim 3 , wherein the supporting link is connected to the drive link at a first secondary pivot axis and is connected to the first mounting plate at a second secondary pivot axis.
5 . The vehicle closure member system as recited in claim 4 , wherein the main link is connected to the first mounting plate at a third secondary pivot axis.
6 . The vehicle closure member system as recited in claim 5 , wherein the main link, the drive link, the supporting link, and the first mounting plate are configured to articulate relative to one another to reorient their respective positions as the closure member moves between the closed position and the fully open position.
7 . The vehicle closure member system as recited in claim 2 , wherein the closure member is mounted to the first mounting plate.
8 . The vehicle closure member system as recited in claim 2 , wherein the power hinge assembly further includes a spring loaded cam assembly that includes a spring, a pawl, and a roller that is mounted to the pawl.
9 . The vehicle closure member system as recited in claim 8 , wherein the roller is received within a first detent of a pivot housing of the main link when the closure member is in the closed position and is received within a second detent of the pivot housing when the closure member is in the fully open position.
10 . The vehicle closure member system as recited in claim 1 , comprising a control module configured to control movement of the closure member between the closed position and the fully open position in response to a predefined prompt or an object detection signal.
11 . A vehicle, comprising:
a vehicle body;
a closure member mounted for movement relative to the vehicle body; and
a power hinge assembly configured to automatically move the closure member during an opening sequence and a closing sequence,
wherein the power hinge assembly is configured to move the closure member along a first swing path during the opening sequence and along a second, different swing path during the closing sequence.
12 . The vehicle as recited in claim 11 , wherein the vehicle is an autonomous vehicle and the closure member is a rear out-swinging door.
13 . The vehicle as recited in claim 11 , wherein the power hinge assembly includes a single electric motor, a main link, a drive link, a supporting link, a first mounting plate, and a second mounting plate.
14 . The vehicle as recited in claim 13 , wherein the first mounting plate is mounted to the closure member, and the second mounting plate is mounted to the vehicle body within a pocket of a panel of the vehicle body.
15 . The vehicle as recited in claim 13 , wherein a first rotational movement of the drive link about a primary pivot axis is configured to initiate a second rotational movement of the main link about the primary pivot axis.
16 . The vehicle as recited in claim 13 , wherein rotation of the drive link about a primary pivot axis is configured to initiate articulations between the drive link and the supporting link at a first secondary pivot axis, between the supporting link and the first mounting plate at a second secondary pivot axis, and between the main link and the first mounting plate at a third secondary pivot axis.
17 . The vehicle as recited in claim 11 , comprising a control module configured to command the power hinge assembly to move the closure member between a closed position and a fully open position in response to receiving a predefined prompt or an object detection signal.
18 . The vehicle closure member system as recited in claim 1 , wherein the closure member is a swinging door that is part of a dual out-swinging door system.
19 . The vehicle closure member system as recited in claim 18 , wherein the rear out-swinging door is mounted at a rear-most end of a motor vehicle comprising the vehicle closure member system.
