Description
Technical field
It the utility model is related to a kind of voice coil motor.
Background technology
Voice coil motor has high frequency sound, high-precision feature.Its cardinal principle is in a permanent-magnetic field, passes through change
The DC current of motor interior loop, to control the stretch position of spring leaf, moved up and down so as to drive, realize focusing.Mobile phone is taken the photograph
As head widely realizes automatic focusing function using VCM, the position of camera lens can be adjusted by VCM, clearly image is presented.
Existing voice coil motor is all the side that coil is wound on to support, and coil periphery set magnetite, i.e., magnetite with
Coil forms horizontal setting, and the coil after energization is surrounded to form magnetic field by magnetite, and according to left hand rule, the coil of energization passes through magnetic
When, the power perpendicular to magnetic field line can be produced, i.e., the caused sense of current after coil electricity, can make support formed to
Upper or downward power, makes supporting band index glass head move up and down change focal length, realizes the purpose of sharp image.
The utility model people is in line with constantly bringing forth new ideas and improveing to product, deeply design, and actively research has a fling at and developed
Design the utility model.
Utility model content
The purpose of this utility model is to provide a kind of entirely different with existing voice coil motor design principle, but can reach phase
With the voice coil motor of effect.
In order to reach above-mentioned purpose, solution of the present utility model is：
A kind of voice coil motor, it includes：One pedestal, a yoke plate, a support, a coil and a magnetite, pedestal are in yoke plate
It is combined together up and down, the support, coil and magnetite are arranged in pedestal and yoke plate, and the periphery of the support is fixed with the magnetic
Stone, the coil are fixed on pedestal and are correspondingly arranged at the underface of magnetite.
Shell fragment is additionally provided between the cradle top surface and the inner top surface of yoke plate, is also set between cradle bottom surface and base top surface
There is lower shell fragment.
The magnetite is annularly fixed on the periphery of support, and the magnetite is annularly fixed on the top surface of pedestal.
The pedestal is provided with the convex wall fixed for the coil, and coil is fixed on the convex wall.
After said structure, coil and magnetite are correspondingly set up and down by the utility model voice coil motor, and magnetite is fixed
On support, coil is fixed on pedestal, and according to Ampere's law, the sense of current after coil electricity determines the N poles of coil upward
Or down, the coil interacts with magnetite thereon, drives support upwardly or downwardly to act, makes above and below supporting band index glass head
It is mobile to change focal length, realize the purpose of sharp image.The utility model and existing voice coil motor design principle are entirely different, existing
It is to utilize left hand rule to have voice coil motor, by coil and magnetite in being horizontally disposed with, passes through coil and the Lorentz force of magnet
The effect of (Lorentz Force) makes support do axial movement.

Embodiment
In order to which the technical solution of the utility model is explained further, the utility model is entered below by specific embodiment
Row elaborates.
As shown in Figures 1 to 4, the utility model discloses a kind of voice coil motor, and it includes what is set gradually from top to down
Yoke plate 1, upper shell fragment 2, support 3, lower shell fragment 4 and pedestal 5, pedestal 5 are in be combined together up and down with yoke plate 1, upper shell fragment 2, support 3
And lower shell fragment 4 is arranged on pedestal 5 with setting upper shell fragment 2, branch in yoke plate 1, between the inner top surface of the top surface of support 3 and yoke plate 1
Lower shell fragment 4 is set between the bottom surface of frame 3 and the top surface of pedestal 5.The outer ring of the support 3 is provided with a magnetite 6, and the pedestal 5 is provided with
The coil 7 of face magnetite 6.
The magnetite 6 is annularly fixed on the periphery of support 3, and coil 7 is annularly fixed on the top surface of pedestal 5, set on pedestal 5
There is a convex wall 51 fixed for the coil, coil 7 can mode be fixed on convex wall 52 by the way that winding or glue be solid etc., the N poles of magnetite 6
Or S, one of extremely towards coil 7, with the N poles of the magnetite 6 upward, S poles illustrate the present embodiment exemplified by down.
When coil 7 is powered, according to Ampere's law, if the electric current of control coil 7 is in clockwise direction, the N of the coil 7
Down, upward, the S poles of the coil 7 are repelled each other with the S poles of surface magnetite 6 for S poles for pole, make magnetite 6 drive support 3 to move up；If
The electric current of control coil 7 in counterclockwise, then the N poles of the coil 7 upward, the N poles of the coil 7 and the S poles of surface magnetite 6
It is attracting, magnetite 6 can be made to drive support 3 down to move, upper shell fragment 2 and lower shell fragment 4 provide reaction force, come balance coil 7 with
Caused interaction force between magnetite 6, makes support 3 be moved to predetermined position, so that the camera lens on support 3 reaches focusing
Purpose.
Coil 7 and magnetite 6 are correspondingly set up and down by the utility model voice coil motor, and coil 7 is fixed on pedestal 5, and
Magnetite 6 is fixed together with support 3, with the two of the opposite end of magnetite 6 in the magnetic field according to caused by Ampere's law uses the power on coil 7
Magnetic pole is mutually exclusive or attracts each other（Magnetic pole of the same name mutually repels, synonyms pole mutually attracts）Make what is be combined together with magnetite 6
Support 3 moves up, and support 3 drives camera lens to move up and down change focal length, realizes the purpose of sharp image.
Above-described embodiment and schema and non-limiting product form of the present utility model and style, any art
The appropriate change or modification that those of ordinary skill is done to it, all should be regarded as not departing from patent category of the present utility model.
