Abstract:
A door lock actuator for manipulating the lock state of an automotive door comprising:a drive motor having a first output shaft with a first output gear coupled thereto;a paddle coupled to said output gear for rotation therewith;an indexing pin plate having a plurality of pins extending from a top thereof, said plurality of pins including at least one top override pin and being positioned on said plate for successive contact with said paddle upon rotation of said paddle;a drive gear adapted for rotation with said indexing pin plate, said drive gear having at least one bottom override pin extending from a bottom thereof;a second output shaft with a second output gear mounted thereon and at least one output cam mounted to an end thereof, said second output shaft being coupled to said drive gear for rotation upon rotation of said drive gear; andtop and bottom override arms coupled to a drive shaft of a key cylinder for movement upon rotation of said key cylinder, said top override arm having an end adapted for contacting said at least one top override pin, and said bottom override arm having an end adapted for contacting said at least one bottom override pin;wherein upon rotation of said key cylinder in a first range of angular rotation an electrical power source is connected to energize said drive motor, thereby causing rotation of said paddle and contact of said paddle with successive ones of said plurality of indexing pins, said paddle thereby rotating said second output shaft and said at least one cam through said drive gear and said second output gear, andwherein upon rotation of said key cylinder in a second range of rotation said top override arm contacts said at least one top override pin for thereby rotating said second output shaft and said at least one cam to a first position through said drive gear and said second output gear; andwherein upon rotation of said key cylinder in a third range of rotation said bottom override arm contacts said at least one bottom override pin for thereby rotating said second output shaft and said at least one cam to a second position through said drive gear and said second output gear.
