Abstract
The utility model discloses a kind of lens driver of novel voice coil motor, comprise 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.The beneficial effects of the utility model are: compared with the prior art, and parts are reduced to 6, and amount of parts greatly reduces.After adopting new relation of fitting a straight line, the processing of parts is more simple, and precision is protected, and due to the relatively planform of rule and the cooperation of plane, directly uses robotization to produce in batches.
Description
Technical field
The utility model 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.
Utility model content
The utility model object is just to overcome above-mentioned deficiency, provides a kind of lens driver of novel voice coil motor.
For achieving the above object, the utility model 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.
Further, described lens supports body is provided with the boss of two evaginations outside end face.
Further, the upper end face of described lens supports body is provided with four counterbores.

Below in conjunction with accompanying drawing, the utility model is described in further detail:
The lens driver of a kind of novel voice coil motor as shown in Fig. 1 Fig. 2, comprises stator module, rotor assembly and base; Described stator module comprises shell 1, front spring 2 and magnetite 4, and described front spring 2 is built in shell 1, and described shell 1 inwall is provided with equally distributed magnetite 4; Described rotor assembly comprises lens supports body 3 and rear spring 5, and described lens supports body 3 bottom nested is in rear spring 5; Described rotor assembly is nested on the reference column inside base 6, and described stator module carries out screens by the arcwall face of base 6 periphery; The axle center of described stator module, rotor assembly and base 6 is positioned on the line of same axis.Shell 1, lens supports body 3, magnetite 4 adopt linear fit structure, are more easily guaranteed to the machining precision of these three components, and it is easier that assembly precision controls.
As shown in Figure 3, described lens supports body 3 is provided with the boss 3a of two evaginations outside end face, coil can directly be wound on above lens supports body 3, and the end of a thread extended position is directly wrapped in lens supports body 3 and gives prominence on small boss 3a.
As shown in Figure 4, the upper end face of described lens supports body 3 is provided with four counterbore 3b.Described counterbore 3b is circular or square or other shapes and have certain reasonable depth, utilizes this structure precisely can carry out Static product test.
As shown in Figure 5, the upper surface of described base 6 is provided with two terminal 6a.Terminal 6a and base 6 one-body molded.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion made according to the technical solution of the utility model, all falls within protection domain of the present utility model.
