Patent ID: 6967822

Claim:
An impact rebound crash stop for an actuator, wherein said actuator includes an actuator magnet assembly with yoke collection comprising a top yoke and a bottom yoke, and includes a voice coil magnet in an actuator arm, wherein said impact rebound crash stop is comprised of: a rigid plastic body containing a pivot between said top yoke and said bottom yoke coupling said impact rebound crash stop to said actuator magnet assembly; a latch bias tab rigidly affixed to said rigid plastic body and magnetically attracted to said voice coil magnet when said actuator arm is near said crash stop; wherein said rigid plastic body is comprised of a pusher face and a crash stop face; wherein said actuator arm includes an actuator tail comprising a pusher stop face and a crash stop site; wherein whenever said actuator arm is near said crash stop, said crash stop pivots bringing said pusher face into a rotational path of said pusher stop face leading to said pusher face engaging said pusher stop face; wherein whenever said pusher face engages said pusher stop face, said crash stop pivots, engaging said crash stop face and said crash stop site; and wherein whenever said crash stop face engages said crash stop site and a first voltage is applied to said voice coil magnet, said voice coil magnet magnetically acts against said actuator magnet assembly repelling said crash stop site from said crash stop face.
