Abstract
The invention discloses a novel voice coil motor lens driving device, which comprises a stator assembly, a rotor assembly and a base, wherein the stator assembly comprises a shell, a front spring and magnets, the front spring is arranged in the shell, and the inner wall of the shell is provided with uniformly-distributed magnets; the rotor assembly comprises a lens support and a rear spring, and the lower part of the lens support is sleeved in the rear spring; the rotor assembly is sleeved on a positioning column at the inner side of the base, and the stator assembly is clamped via an arc-shaped surface on the periphery of the base; and axle centers of the stator assembly, the rotor assembly and the base are located on the same central axis. Compared with the prior art, the novel voice coil motor lens driving device has the beneficial effects that the number of spare parts is reduced to 6, and the number of the spare parts is greatly reduced. After a novel straight line fit relationship is adopted, processing of the spare parts is simpler, the precision can be ensured, and due to a relatively regular structure shape and plane fit, mass production can be carried out automatically.
Description
Technical field
The present invention relates to a kind of lens driver, particularly a kind of lens driver of novel voice coil motor, for the camera of automatic focusing function, be applied particularly to mobile phone, camera, the equipment such as video camera or detecting sensor vision system, robotic vision system with camera function.
Background technology
Scheme disclosed in the lens driver disclosed in similar lens driver many employings China Patent Publication No. CN1683946A that existing domestic and international minisize pick-up head adopts, stationary part is all made up of iron-clad and four equiform magnetites, and described magnetite is assembled in four corners of iron-clad respectively; Coil and lens supports body are fixed together, be placed in stator interior, lens driver described in this lens supports body is mobile forwards, backwards in the iron-clad of stator and the inner centrally direction of magnetite together with coil also comprises front to spring and rear to spring, their peripheries are fixedly connected with iron-clad and fixed lens supporter, front also has a framework to be fixed on iron-clad by front to spring, the electromagnetic force produced after coil electricity overcomes the precompressed elastic force that front produces to spring and rear to spring, orders about lens supports body and moves along optical axis direction.
About this lens driver constitutional detail all needs 12 parts, complex structure, part is many, and packaging technology is many, and function realizes AF function only.
Summary of the invention
The object of the invention is just to overcome above-mentioned deficiency, provides a kind of lens driver of novel voice coil motor.
For achieving the above object, the present invention is achieved through the following technical solutions:
A lens driver for novel voice coil motor, comprises stator module, rotor assembly and base; Described stator module comprises shell, front spring and magnetite, and described front spring is built in shell, and described outer casing inner wall is provided with equally distributed magnetite; Described rotor assembly comprises lens supports body and rear spring, and described lens supports body bottom nested is in rear spring; Described rotor assembly is nested on the reference column inside base, and described stator module carries out screens by the arcwall face of base outer perimeter; The axle center of described stator module, rotor assembly and base is positioned on the line of same axis.
