Camera Module

摘要

The present invention relates to a camera module, the module including: a PCB; an image sensor mounted on the PCB and formed with an image pickup device; a base mounted on the PCB and including a plated portion formed at a lower center with an opening mounted with an IR filter; a lower spring plate formed with a conductive material; a spacer arranged on an upper surface of the lower spring plate and forming a staircase structure by a rib wrapping a periphery of the lower spring plate to supportively apply a pressure to the lower spring plate; a lens actuator including a bobbin, and a yoke; an upper spring plate coupled to an upper surface of the lens actuator; and a cover arranged on an upper surface of the upper spring plate.

主权项

1. A camera module, the camera module comprising:
a printed circuit board (PCB); an image sensor mounted on the PCB; a base mounted on the PCB and including a lower plate portion with an opening, and a first pillar portion formed on a corner of the lower plate portion; an infrared (IR) filter coupled to the base; a lens actuator including a bobbin, a coil arranged around the bobbin, and a yoke wrapping the periphery of the bobbin; a lens assembly coupled to the bobbin and configured to move in a vertical direction; a cover including an upper plate formed with a hole and a second pillar portion formed at a corner of the upper plate of the cover to be coupled to the first pillar portion of the base; an upper spring disposed between the cover and the lens actuator; a lower spring including a first spring and a second spring separated from the first spring, wherein the lower spring is coupled to the base; wherein the lower spring is insulated from the yoke of the lens actuator; and wherein the yoke is pinched by the base and the cover to expose a lateral surface thereof out of the cover between the mutually coupled first pillar portion of the base and the second pillar portion of the cover, wherein a portion of the first pillar portion is formed in a staircase that has a large horizontal cross section portion and a small horizontal cross section portion integrally extended from the large cross section portion, and wherein a portion of the second pillar portion is formed in a staircase that has a large horizontal cross section portion and a small horizontal cross section portion integrally extended from the large cross section portion.
