Problems solved by technology

[0003] Most of the traditional voice coil motors can only drive the mobile phone camera to move back and forth, and the focusing effect is not good
There are also some voice coil motors that can achieve horizontal movement anti-shake, but cannot achieve voice coil motor rotation anti-shake, or achieve rotation anti-shake effect alone
[0004] Secondly, the sensor assembly is not movable and has high installation loss

Abstract

The invention belongs to the technical field of optical anti-shake, and in particular relates to an anti-shake mechanism, a lens driving device, an imaging device and electronic equipment. It solves the technical problem that the existing voice coil motor cannot realize rotation anti-shake. The anti-shake mechanism of the lens driving device includes a housing with a cavity inside; the outer moving body is suspended in the cavity through an elastic support and the outer moving body is used to carry the sensor assembly; the inner moving body is suspended in the cavity and It is used to carry the lens carrier; the suspension wire structure is respectively connected to the outer moving body and the inner moving body so that the inner wall of the outer moving body is spaced apart from the outer wall of the inner moving body; the driving component is used to drive the inner moving body to rotate around the optical axis. The invention has the advantages that it can realize rotation anti-shake, and can greatly improve the definition of image shooting.

Description

technical field [0001] The invention belongs to the technical field of optical anti-shake, and in particular relates to an anti-shake mechanism, a lens driving device, an imaging device and electronic equipment. Background technique [0002] The existing voice coil motor mainly includes a lens, a lens holder, a magnet, a coil, a shrapnel and a casing, and the casing is square. The voice coil motor has the characteristics of high frequency response and high precision. Its main principle is to control the stretching position of the spring leaf by changing the DC current of the inner coil of the motor in a permanent magnetic field, so as to drive the up and down movement to achieve focusing. Mobile phone cameras widely use VCM to realize the auto-focus function, through which the position of the lens can be adjusted to present a clear image. [0003] Most of the traditional voice coil motors can only drive the mobile phone camera to move back and forth, and the focusing effec...
