Lens driving motor and elastic member of the same

摘要

Provided are a lens driving motor and an elastic member of the lens driving motor. The elastic member of a lens driving motor, the elastic member includes a first spring and a second spring. The second spring is different from the first spring and disposed together with the first spring on one side of a carrier to support the carrier. A first lead line of a coil and a first external power source are connected to the first spring, and a second lead line of the coil and a second external power source are connected to the second spring to supply power to the coil. Since the carrier can be assembled to other part after a (+) lead line and a (−) lead line of the coil are connected to the first and second springs, respectively, using solder, a process is simple and convenient.

主权项

1. A lens driving motor comprising:
a base; a yoke disposed on the base; a magnet disposed in the yoke; a carrier disposed on the base and configured to move in a vertical direction; a coil coupled to the carrier; and a lower elastic member coupled to a lower portion of the carrier and configured to provide elastic force to the carrier, wherein the lower elastic member comprises a first spring physically and a second spring physically separated from the first spring, wherein the first spring includes a first outer portion and a first inner portion spaced apart from the first outer portion, and a first part of the first outer portion is connected to a first part of the first inner portion, wherein the second spring includes a second outer portion and a second inner portion spaced apart from the second outer portion, and a first part of the second outer portion is connected to a first part of the second inner portion, wherein the first outer portion includes a first terminal connected to a first external power source, the first terminal extending in a first outward direction, wherein the second outer portion includes a second terminal connected to a second external power source, the second terminal extending in the first outward direction, and wherein the first terminal is adjacent to the second terminal.
