ROTARY ACTUATION MECHANISM

摘要

A rotary actuation mechanism is disclosed. The rotary actuation mechanism can include an actuator having a body, and a slider movable on a linear path relative to the body. A first linkage can be pivotally coupled to the body at a first pivot having a first axis. A second linkage can be pivotally coupled to the slider at a second pivot having a second axis, and pivotally coupled to the first linkage at a third pivot. A length of the first linkage between the first pivot and the third pivot can be equal to a length of the second linkage between the second pivot and the third pivot. The slider can be movable to position the second axis in a collinear relationship with the first axis. The rotary actuation mechanism can include an anti-singularity device to constrain movement of the body when the first axis and the second axis are in the collinear relationship.

1. A rotary actuation mechanism, comprising:
an actuator having a body and a slider movable on a linear path relative to the body; a first linkage pivotally coupled to the body at a first pivot having a first axis; a second linkage pivotally coupled to the slider at a second pivot having a second axis, and pivotally coupled to the first linkage at a third pivot, wherein a length of the first linkage between the first pivot and the third pivot is equal to a length of the second linkage between the second pivot and the third pivot, wherein the slider is movable to position the second axis in a collinear relationship with the first axis; and an anti-singularity device to constrain movement of the body when the first axis and the second axis are in the collinear relationship.
