Abstract

The invention relates to a camera module. The camera module comprises a pedestal (400), a housing (200) which is matched with the pedestal (400), and is hollow and provided with an opening in the top surface, and a camera lens assembly (100) and a carrier (300) which are accommodated in the housing (200). The camera module also comprises at least two sets of moving members (600) arranged between the outer wall of the carrier (300) and the housing (200), and the camera lens assembly (100) is accommodated in the carrier (300) and moves relative to the pedestal (400) through the at least two sets of moving members (600). The camera module has distinctive advantages that the camera module is simple in internal structure, convenient to carry, fast in focusing response speed, stable in focusing performance and good in imaging effect.

Description

technical field [0001] The present invention relates to a photographing device, more specifically, to a camera module with an auto-focus function. Background technique [0002] In order to be convenient for users to carry, most of the photographing devices on the market adopt a lightweight design, and the internal space thereof is designed to be more and more compact. However, due to the limitation of internal space, this kind of shooting device usually has a built-in voice coil motor, and the focus is achieved through the shrapnel structure, so there are performance defects of slow focusing speed, low focusing accuracy, and unstable focusing. Contents of the invention [0003] The purpose of the present invention is to provide a simple structure, portable camera, aiming at the technical defects of slow focusing speed, low focusing precision, and insufficient focusing stability in the shooting device with a built-in voice coil motor and focusing through a shrapnel structur...
