Abstract
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.
Claims27
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, a first pillar portion formed on a corner of the lower plate portion, a first hole, and a second hole;
- an infrared (IR) filter coupled to the base;
- a lens actuator including a bobbin disposed over the base, and accommodated inside with a lens assembly, a coil arranged at a periphery of the bobbin, and a yoke wrapping the periphery of the bobbin and coupled to the base;
- 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 having an elastic support portion and coupled to the cover and the lens actuator to elastically support the bobbin;
- a lower spring coupled to the base and the lens actuator to elastically support the bobbin, the lower spring including a first spring and a second spring separated from the first spring;
- and
- a spacer arranged at an upper surface of the first spring and a lower surface of the yoke,
- 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 to provide air-tight coupling,
- wherein the first spring includes a first extension portion extended towards the PCB and electrically connected to the PCB,
- wherein the second spring includes a second extension portion extended towards the PCB and electrically connected to the PCB,
- wherein the lower spring is arranged between the lower plate portion of the base and a lower portion of the yoke,
- wherein the upper spring is arranged between an upper portion of the yoke and a lower portion of the cover,
- wherein the first extension portion is inserted into the first hole of the base and the second extension portion is inserted into the second hole of the base, and
- wherein a portion of the first extension portion and a portion of the second extension portion are disposed within the base.
