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 motor for driving a lens, the motor comprising:
a base; a yoke disposed on the base; a carrier disposed in the yoke and configured to move in a vertical direction; a magnet disposed at an inner surface of the yoke; a coil disposed at an outer peripheral surface of the carrier while facing the magnet; an upper elastic member coupled to an upper portion of the carrier; and a lower elastic member coupled to a lower portion of the carrier, wherein the lower elastic member comprises a first spring and a second spring separated from the first spring, wherein the first spring and the second spring each comprises an outer section, an inner section, and a connection section connecting the inner section and the outer section, wherein the coil includes a first end portion and a second end portion, wherein a portion of the inner section of the first spring is soldered to the first end portion, and wherein a portion of the inner section of the second spring is soldered to the second end portion.
