Abstract

The invention discloses a voice coil motor, which comprises a housing assembly, a base assembly, a zoom lens bracket, a first electromagnetic drive assembly, a focus lens bracket and a second electromagnetic drive assembly; the zoom lens bracket and the focus lens bracket are arranged on the housing In the accommodation space formed by the assembly and the base assembly, the first electromagnetic drive assembly is used to drive the zoom lens bracket to move in the front and rear direction, and includes a first magnetic steel part and a first coil opposite to the first magnetic steel part; The electromagnetic driving assembly is used to drive the focusing lens bracket to move in the front-rear direction, and includes a second magnetic steel part and a second coil opposite to the second magnetic steel part. The voice coil motor provided by the present invention can reduce the time-consuming during the zooming process, thereby preventing the stuck phenomenon during the zooming process, so that electronic products can be used normally.

Description

technical field [0001] The invention relates to the technical field of imaging of electronic products, in particular to a voice coil motor. Background technique [0002] A camera module of an electronic product usually includes a focusing unit and a zoom unit disposed in a casing, wherein the focusing unit is used to focus the camera module, and the zoom unit is used to zoom the camera module. [0003] In the prior art, the zoom unit includes a fixed bracket and a first lens and a second lens both fixed on the fixed bracket, wherein the first lens has a zoom function, and the second lens is an ordinary lens without a zoom function. When the zoom function needs to be realized through the zoom unit, the first lens and the second lens are usually used to calculate and analyze through specific software. [0004] Because when using the zoom function, the image displayed in the camera module cannot be directly enlarged or reduced, but needs to be analyzed and calculated by the so...
