Anti-backdrive actuator assembly

摘要

An actuator assembly may include a drive, a gear set coupled with the drive, an interface member coupled to the gear set, and an output coupled to the interface member. In at least one position of the interface member the gear set binds to prevent backdrive of the output.

1. An actuator assembly, comprising:
a ring gear; a sun gear having an axis; a planet gear meshed with the sun gear and the ring gear and configured to rotate about an axis of the planet gear; a drive member offset from the planet gear axis of rotation; a carrier on which the planet gear is mounted to rotate about the planet gear axis of rotation and to rotate with the carrier about an axis of the carrier; an interface member engaged with the drive member and moved by the drive member during at least a portion of the movement of the drive member; and an output coupled to the interface member to move with the interface member, wherein the drive member moves relative to the interface member as the planet gear rotates and in at least one position of the drive member relative to the interface member a backdrive movement of the output is prevented.
