Embodiment Construction

[0013] The invention will be described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the descriptions of the specific embodiments are only used to explain the technical solutions proposed by the present invention, not to limit the present invention.

[0014] figure 1 , figure 2 An embodiment of the present invention is given. In this embodiment, a voice coil motor that realizes optical anti-shake through pure translational motion includes: a housing composed of a lower cover 10 and a metal yoke 2, and a device is installed inside the housing. There is a lens mount 5 with a lens, and a focus coil is sheathed on the periphery of the lens mount 5. Four magnets 4 are evenly spaced and fixed on the four inner walls of the yoke, and the polarities of the four magnets 4 facing the focus coil side are all the same. The translation coils 9 are respectively fixed on the lower cover 10 below the magnet 4, wherein the two di...

Abstract

The invention discloses a voice coil motor capable of realizing OIS (optical image stabilization) through pure translational motion. The voice coil motor comprises a case consisting of a lower cover and a metal magnet yoke, a lens holder arranged in the case, a plurality of magnets arranged on inner walls of the magnet yoke, a focusing coil capable of interacting with the magnets to control focusing of the lens holder, translation coils capable of interacting with the magnets to control the lens holder to move in a plane perpendicular to the lens optical axis, a fixing device and a limiting device, wherein the lens holder can move back and forth along the optical axis relative to the fixing device, and the limiting device fixes the lens holder in the plane perpendicular to the optical axis. The fixing device and the limiting device are matched, so that the translational motion of an automatic focusing part can be conducted in one plane, the deflection can be avoided, and the image stabilization effect is very ideal.

Description

technical field [0001] The present invention relates to voice coil motors used in electronic equipment accessories. Background technique [0002] With the increasing popularity of smart phones, people have higher and higher technical requirements for taking photos with smart phones, expecting that the camera effect of mobile phones can reach the level of digital cameras. The digital camera can realize the functions of optical image stabilization (OIS) and tilt-shift photography because it has a relatively complex mechanical structure to control the multi-dimensional movement of the lens, but this complex mechanical structure cannot be applied to mobile phones, because the mobile phone itself The hardware and software foundation of the limited the further development of its camera. [0003] In order to improve the camera's camera capability on the basis of the hardware and software of the mobile phone itself, it is also a topic that smartphone manufacturers have been working...
