Description
Technical field
The present invention relates to lens driver, particularly relate to the lens driver of a kind of simple and easy voice coil loudspeaker voice coil motor, for the camera of auto-focusing function, it is applied particularly to the equipment such as mobile phone, photographic camera, pick up camera or detecting sensor vision system, the 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 the magnetite that iron-clad is the same with four shapes, and described magnetite is assembled in four corners of iron-clad respectively; Coil and lens supports body are fixed together, it is placed in stator interior, this lens supports body together with coil in the inner centrally direction of the iron-clad of stator and magnetite mobile forwards, backwards described in lens driver also comprise front to spring and rear to spring, their peripheries are fixedly connected with iron-clad and fix lens supports body, 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 to spring and rear, orders about lens supports body and moves along optical axis direction.
This kind of lens driver structure positions guiding mainly through shell, and about all needing 12 parts, complex structure, part is many, assembles complex process and defect ware easily occurs, and function realizes AF function only.
Summary of the invention
In order to overcome above-mentioned defect, the present invention provides a kind of structure simple, and positioning and guiding is accurate, the lens driver of the simple and easy voice coil loudspeaker voice coil motor that component are few, simple for assembly process.
In order to realize above-mentioned purpose, the technical scheme of the present invention is: the lens driver of a kind of simple and easy voice coil loudspeaker voice coil motor, comprise base, take base as benchmark, upwards it is provided with rear spring successively, lens supports body and shell, described base corner is respectively equipped with locating dowel, it it is arc outside described locating dowel, on the base of described locating dowel side, plane is provided with steady brace, the phase opposite of described adjacent positioned post is the vertical surface being parallel to each other, described rear spring by steady brace and vertical surface screens on base, described lens supports body carries out screens by four locating dowels after being nested in the inner circumferential of rear spring again, described lens supports is external is equipped with coil, it is provided with magnetite in described shell and carries out screens by the arc outside locating dowel.
Further, described locating dowel upper surface is provided with front spring, is located by pin between described front spring and locating dowel.
Further, a glue groove it is provided with outside described locating dowel.
The invention has the beneficial effects as follows: structure simple optimizing, component only 6 or 7, location all rely on base and on locating dowel complete, emphasis management and control factor also reduces on a part, and positioning precision is more prone to management and control. Owing to part significantly reduces, therefore assembling technique and more optimize, technique is simpler; AF function and two-section type function can be realized, reduce costs, by arranging front spring, the stability of optical axis can be improved further in addition.
