Multi-phase closure check link mechanism
View Patent ↗A check link mechanism for a closure pivotally connected to a vehicle. The check link mechanism includes a check link rotatable about a central axis, and is operably connected to the vehicle. The check link has a cam surface and a free surface, which is rotated about the central axis relative to the cam surface. A detent assembly is configured to apply a substantially-constant detent force to the check link. An actuator is configured to selectively rotate the check link between at least a holding position and a free position. The holding position aligns the cam surface to be substantially perpendicular to the substantially-constant detent force, and the free position aligns the free surface to be substantially perpendicular to the substantially-constant detent force.
1. A check link mechanism for a closure pivotally connected to a vehicle, the check link mechanism comprising:
a check link rotatable about a central axis and operably connected to the closure and to the vehicle, the check link having:
a cam surface, and
a free surface, wherein the free surface is rotated about the central axis relative to the cam surface;
a detent assembly configured to apply a substantially-constant detent force to the check link; and
an actuator configured to rotate the check link between at least:
a holding position, which aligns the cam surface to be substantially perpendicular to the substantially-constant detent force, and
a free position, which aligns the free surface to be substantially perpendicular to the substantially-constant detent force.
2. The check link mechanism of claim 1 , wherein the free surface is rotated from the cam surface by approximately forty-five degrees.
3. The check link mechanism of claim 1 , wherein the free surface is rotated from the cam surface by approximately ninety degrees.
4. The check link mechanism of claim 1 , wherein the actuator is a mechanical actuator controlled by a first input device located on the closure, wherein the first input device has a mechanical connection to the actuator.
5. The check link mechanism of claim 1 , wherein the detent assembly includes two detent buttons applying the substantially-constant detent force, such that the two detent buttons contact the cam surface when the check link is in the holding position.
6. The check link mechanism of claim 5 , wherein the two detent buttons apply the substantially-constant detent force to opposite sides of the check link.
7. The check link mechanism of claim 1 , wherein the actuator is an electronic actuator controlled by a first input device located on the closure.
8. The check link mechanism of claim 7 , wherein the actuator is also controlled by a second input device located on the vehicle.
9. A check link mechanism for a closure pivotally connected to a vehicle, the check link mechanism comprising:
a check link rotatable about a central axis and operably connected to the closure and to the vehicle, the check link having:
a cam surface, and
a free surface, wherein the free surface is rotated about the central axis relative to the cam surface by approximately ninety degrees;
a detent assembly configured to provide a substantially-constant detent force to the check link; and
an actuator configured to rotate the check link between at least:
a holding position, which aligns the cam surface to be substantially perpendicular to the substantially-constant detent force, and
a free position, which aligns the free surface to be substantially perpendicular to the substantially-constant detent force.
10. The check link mechanism of claim 9 , wherein the actuator is an electronic actuator controlled by a first input device located on the closure.
11. The check link mechanism of claim 9 , wherein the detent assembly includes two detent buttons applying the substantially-constant detent force, such that the two detent buttons contact the cam surface when the check link is in the holding position.
12. The check link mechanism of claim 11 , wherein the two detent buttons apply the substantially-constant detent force to opposite sides of the check link.
13. A check link mechanism for a closure pivotally connected to a vehicle, the check link mechanism comprising:
a check link rotatable about a central axis and operably connected to the closure and to the vehicle, the check link having:
a holding plane intersecting the central axis,
a cam surface substantially parallel to the holding plane,
a free plane intersecting the central axis, wherein the free plane is rotationally offset from the holding plane, and
a free surface substantially parallel to the free plane;
a detent assembly configured to provide a substantially-constant detent force to the check link;
an actuator configured to rotate the check link between at least:
a holding position, which aligns the holding plane to be substantially perpendicular to the substantially-constant detent force, such that the detent assembly applies the substantially-constant force to the cam surface, and
a free position, which aligns the free plane to be substantially perpendicular to the substantially-constant detent force, such that the detent assembly applies the substantially-constant force to the free surface.
14. The check link mechanism of claim 13 , wherein the free plane is offset from the holding plane by approximately ninety degrees.
15. The check link mechanism of claim 13 , wherein the free plane is offset from the holding plane by approximately forty-five degrees.
16. The check link mechanism of claim 13 , wherein the detent assembly includes two detent buttons applying the substantially-constant detent force, such that the two detent buttons contact the cam surface when the check link is in the holding position.
17. The check link mechanism of claim 16 , wherein the two detent buttons apply the substantially-constant detent force to opposite sides of the check link.
