Lens driving device
First Claim
1. A lens driving device, comprising:
- a cover can comprising an upper plate and a side plate extending from the upper plate;
a base coupled to the cover can;
a housing spaced apart from the base and disposed in the cover can;
a bobbin disposed in the housing;
a first coil unit disposed on the bobbin;
a second coil unit disposed on the base,a magnet unit disposed on the housing;
a substrate disposed between the second coil unit and the base; and
a first elastic unit coupled to the bobbin and the housing, wherein the first elastic unit comprises an upper spring disposed on an upper portion of the housing and a lower spring disposed at a lower portion of the housing;
a second elastic unit connected to the upper spring; and
a hall sensor unit disposed on a lower surface of the substrate;
wherein the second coil unit is connected to the substrate by a solder ball,wherein the base comprises a first groove corresponding to the hall sensor unit and a second groove corresponding to the solder ball,wherein the hall sensor unit is disposed in the first groove of the base, andwherein the bobbin comprises at least two flange units protrusively formed at an outer surface thereof, and the housing comprises mounting portions at an inner side surface corresponding to the flange units, respectively, andwherein the magnet unit is disposed in the corner of the housing.
