Abstract
A camera module includes a lens assembly, a voice coil motor assembly for receiving and driving the lens assembly, and an image sensor assembly located below the voice coil motor assembly. The voice coil motor assembly comprises a bottom unit that is hollow and a color filter supported by the bottom unit, the color filter, the lens assembly and the image sensor assembly are coaxial, the bottom unit has an upper portion and a lower portion that are integrated together, the upper portion is configured around the lens assembly, and the bottom unit is configured below the lens assembly and supports the color filter. The camera module has simple structure and convenient assembly, can reduce total assembly tolerances of the camera module, achieve an accurate optical axis alignment between the lens and the image sensor, and reduce manufacturing cost to benefit the popularization in industries.
