Camera lens base and camera module

Abstract

The invention provides a camera lens base which comprises a cylindrical barrel used for allowing a camera lens and a cavity to be installed in, wherein the cavity is connected with the cylindrical barrel and used for accommodating an imaging chip and a PCB ( printed circuit board) / FPC (flexible printed circuit) board, and the cavity comprises a first cavity and a second cavity; the surface of the inner wall of the second cavity in a vertical direction and the surface of the inner wall of the first cavity in a horizontal direction form steps; and the thickness of the wall of the camera lens base of the second cavity is smaller than that of the wall of the camera lens base of the first cavity. The invention further provides a camera module which comprises the camera lens base. According to the camera lens base and the camera module, when the steps on the inner wall of the camera lens base are overlapped on the PCB / FPC board, redundant carrying glue flows into a gap between the wall of the camera lens base below the steps and the PCB / FPC board, and the redundant glue is prevented from overflowing to other positions after the steps are carried, so that the trimming procedure is avoided; and simultaneously, trimming is not required, so that the deviation of the physical dimension of a product is small.

Description

technical field [0001] The invention relates to the technical field of camera modules, in particular to a lens base and a camera module. Background technique [0002] The lens base is a mechanical component in the camera module, which is used to fix the lens on the imaging chip. By adjusting the relative position between the lens and the lens base, the imaging surface of the lens coincides with the imaging chip, that is, focusing.
