CAMERA MODULE

摘要

A camera module according to an embodiment of the present invention may include a first Printed Circuit Board (PCB) configured to have an image sensor mounted thereon; a housing unit disposed over the first PCB; a holder module spaced apart from a bottom surface within the housing unit at a specific interval and configured to have first coils wound on its outer circumferential face and to include at least lens therein; a second PCB combined with the bottom surface of the holder module; a third PCB disposed over the holder module; a plurality of wire springs each configured to have one end connected to the second PCB and the other end connected to the third PCB; and buffer units provided at the connection units of the wire springs and the third PCB and configured to surround the connection units of the wire springs and the third PCB.

主权项

1. An OIS (Optical Image Stabilization) unit, comprising:
a housing unit including a first housing and a second housing arranged at an upper surface of the first housing and centrally formed with an opening; a holder module including an outer blade spaced apart from an inner floor surface of the first housing at a predetermined distance, and a bobbin arranged at an inner surface of the outer blade; a spring member arranged at the outer blade to support a movement of the bobbin to an optical axis; an autofocus driving unit including an autofocus coil arranged at a periphery of the bobbin, and a magnet that interacts with the autofocus coil; an OIS driving unit including a magnet and an OIS coil, the magnet and the OIS coil arranged on the housing unit and the holder module; a plurality of wires that support a movement of the holder module to a direction perpendicular to the optical axis by the OIS driving unit while being spaced apart from the first housing at a predetermined distance, and electrically connected to the autofocus coil through the spring member configured to provide a current to the autofocus coil; and a buffering unit formed by curving or bending the wires and arranged with an adhesive material.
