Abstract
The present disclosure provides an actuator assembly for a mirror head. The actuator includes a tubular member, an inner carriage, an outer carriage, a helix drive shaft and a motor drive. The inner carriage includes one or more inner magnets. The outer carriage is coupled to the mirror head. The outer carriage includes one or more outer magnets magnetically coupled to the one or more inner magnets of the inner carriage. The helix drive shaft is drivably coupled to the inner carriage. The motor drive is configured to rotate the helix drive shaft relative to the tubular member. Upon rotation of the helix drive shaft by the motor drive, the inner carriage translates. The outer carriage also translates along with the inner carriage due to magnetic coupling between the one or more inner magnets and the one or more outer magnets.
