Stabilized camera module

摘要

The present invention relates to a stabilized camera module configured to prevent instable movement of a bobbin caused by outside force, the module including a holder formed at a lateral surface with at least one slit, a bobbin movably coupled to an inside of the holder and having a protruder protruding outside of the holder by penetrating the slit, a lens assembly coupled to an inside of the bobbin and including one or more lenses receiving an optical image of an object, and one or more elastic members formed between the holder and the bobbin to prevent the bobbin from moving to one side of the holder.

1. A module comprising:
a holder formed at a lateral surface with at least one slit; a bobbin movably coupled to an inside of the holder and having a protruder protruding outside of the holder by penetrating the slit; a lens assembly coupled to an inside of the bobbin and including one or more lenses receiving an optical image of an object; one or more elastic members formed between the holder and the bobbin to prevent the bobbin from moving to one side of the holder; and an SMA (Shape Memory Alloy) wire extended between the protruder and the holder, and shrunken or relaxed according to the amount of electric power applied to restrict or permit the movement of the protrude by the shrinking or relaxation of the SMA wire, wherein the protrude moves along the slit, and the movement of the protruder is restricted in the same direction as that of restricting the movement of the bobbin by the elastic member, wherein both ends of the SMA wire are fixed at the holder and a center part of the SMA wire hangs over the protruder.
