Abstract
The present invention relates to a support structure of a camera module, comprising a pedestal and bosses. A bearing surface for bearing an optical filter is provided with at least three bosses, the heights of all the bosses are same, and centers of end faces of at least three bosses are configured to determine a plane. When dispensing is performed on the bearing surface, the thickness of the formed glue layer is the same as the height of the bosses. When the bearing surface is provided with the optical filter, the bosses may be configured to effectively play a supporting role. The effective contact surface between the optical filter and the bearing surface is the areas of the end faces of the bosses, the optical filter is incapable of inclining when being pasted to the support structure, and the flatness may be better controlled. Moreover, the glue between the optical filter and the bearing surface for adhesion is incapable of generating a serious excessive glue phenomenon caused by the extrusion of the optical filter so that the excessive glue phenomenon may be effectively improved and the imaging quality of the camera module may be enhanced.
