Optical anti-shake voice coil motor, camera module and electronic product

Abstract

The embodiment of the invention discloses an optical anti-shake voice coil motor, a camera module and an electronic product. The optical anti-shake voice coil motor comprises a shell, a lower cover, an upper gasket, an OIS elastic sheet, a plurality of magnets, an OIS coil support and a support, wherein the upper gasket, the OIS elastic sheet, the magnets, the OIS coil support and the support arearranged between the shell and the lower cover. The four corners of the upper gasket are correspondingly connected with supporting legs extending out of the four corners of the OIS elastic sheet. Themagnets are uniformly distributed on the support, the support is arranged at the periphery of the OIS coil support, the OIS coil support comprises OIS coils of which the number is the same as that ofthe magnets, the OIS coils and the magnets are arranged in a one-to-one correspondence manner, the bearing translation support is fixed on the lower cover, four corners of the bearing translation support correspond to four corners of the OIS elastic sheet, and at least two translation grooves are formed in the bearing translation support. According to the invention, the bottom of the lens group issupported in a translatable manner, a Hall device on the OIS VCM design is removed, the difficulty of the anti-interference design is reduced, the cost is reduced, and the assembly yield is improved.

Description

technical field [0001] The present application relates to the technical field of voice coil motors, in particular to an optical anti-shake voice coil motor, a camera module and electronic products. Background technique [0002] OIS (Optical Image Stabilizer, Optical Image Stabilizer) voice coil motor, commonly known as optical anti-shake voice coil motor, is a device that converts electrical energy into mechanical energy and can realize linear and limited swing angle motion. It is used in electronic The lens in the product, in addition to realizing the auto-focus function of the lens, can also effectively overcome the image blur caused by lens shake. [0003] During the research and practice of the prior art, the inventors of the present invention found that the traditional optical image stabilization voice coil motor (OIS VCM) used in the mobile terminal camera module is complicated in design, especially the design of two sets of coils and two sets of magnets , not only th...
