Abstract

A compartment actuator ( 20 ) includes a motor ( 22 ) and a drive gear ( 32 ) driven by the motor ( 22 ) about an axis of rotation between a first position and a second position. The drive gear ( 32 ) has a groove ( 36 ) formed therein and the groove ( 36 ) is eccentric about the axis of rotation.

First claim

What is claimed is:

1. A compartment actuator comprising:
a pawl;
a motor; and
a drive gear driven by the motor about an axis of rotation between a first position and a second position, the drive gear having a curved groove for receiving a pawl, the pawl being movable out of engagement with the drive gear, the groove has a first end and a second end connected by a central portion, and at least one of the first end and the second end includes at least one ramp-like surface extending relative to the axis of rotation for opposing a biasing force acting on the pawl, wherein the groove is eccentric about the axis of rotation such that a radial distance between the groove and the axis of rotation varies about the groove; and
wherein when the drive gear is in the first position, the pawl is receivable at one of the first end and the second end of the groove and when the drive gear is in the second position, the pawl is arranged within the central portion of the groove.

2. The compartment actuator of claim 1 , wherein as the drive gear rotates between the first position and the second position, the pawl receivable within the groove translates along a pawl axis relative to the drive gear.

3. The compartment actuator of claim 2 , wherein the pawl axis is substantially perpendicular to the axis of rotation of the drive gear.

4. The compartment actuator of claim 2 , wherein as the drive gear rotates from the first position to the second position, the pawl translates inwardly toward a center of the drive gear.

5. The compartment actuator of claim 2 , wherein the pawl translates about up to 20 mm.

6. The compartment actuator of claim 1 , further comprising:
a switch for communicating with the motor; and
a feature extending from the drive gear, wherein the feature engages and activates the switch as the drive gear rotates between the first position and the second position.

7. The compartment actuator of claim 6 , wherein the feature does not engage the switch when the drive gear is in the first position and the second position.

8. The compartment actuator of claim 6 , further comprising an activator pin coupled to the drive gear, wherein the activator pin and the switch are aligned when the drive gear is in the first position, the switch being operable by the pawl via the activator pin.

9. The compartment actuator of claim 6 , further comprising a secondary switch for communicating to the motor a signal to rotate the drive gear from the second position to the first position, the secondary switch being located remotely from the compartment actuator.

10. The compartment actuator of claim 1 , wherein the first position of the drive gear is associated with a partially closed position of a compartment door and the second position of the drive gear is associated with a fully closed position of the compartment door.

11. The compartment actuator of claim 1 , wherein the drive gear is rotatable between a first position and a second position in a first direction about the axis of rotation.

12. The compartment actuator of claim 11 , wherein the drive gear is rotatable from a second position to a first position in the first direction and a second opposite direction about the axis of rotation.

13. The compartment actuator of claim 11 , wherein the drive gear is rotatable in a second direction about the axis of rotation in response to a failure of the actuator.
