Description
Technical field
The present invention relates to the voice coil motor being used in electronic equipment accessory.
Background technology
Current electronic equipment such as smart mobile phone, panel computer etc., the camera voice coil motor technology of these products is
It is highly developed.Voice coil motor is referred to as（VCM）, it is mainly made up of coil, group of magnets and shell fragment, and coil passes through upper and lower two shell fragments
It is fixed in group of magnets, when the coil is energized, coil can produce magnetic field, coil magnetic field and magnetite group interact, coil can be to
Upper movement, and be locked in the camera in coil and also can move together therewith, when the coil is de-energized, coil is acted in the elastic force of shell fragment
Lower playback, is so achieved that automatic focusing function.The material of shell fragment be copper alloy, thickness be generally 0.03 ~ 0.06mm, make
Technics comparing is complicated, and manufacture difficulty is also higher, therefore only several manufacturers can make shell fragment in the world, therefore result in
The cost of voice coil motor is of a relatively high, and due to the very thin thickness of shell fragment, is easy to damage in the production process of voice coil motor
Bad or deformation, causes the fraction defective of voice coil motor production to improve, and also brings integrity problem, motor to be easy to damage failure.
The content of the invention
The invention aims to solve problem present in above-mentioned technology, it is proposed that a kind of magnetcisuspension suspension motor, including
Shell, the lens mount located inside the shell, multiple first magnetites and the first magnetite being made up of bottom and yoke interacts and controls
Lens mount focusing focusing coil, also include with the first magnetite interact produce repulsive force lens mount is pressed in it is many on bottom
Individual second magnetite.
Wherein, first magnetite is distributed on periphery of the lens mount near yoke one end, second magnetite and the first magnetic
Stone staggers one by one, polarity is relatively uniformly fixed in yoke.
In the first embodiment of the technical program, coil of focusing is fixed on the lower section of the second magnetite in yoke, and by first
Magnetite is non-contiguously trapped among in focusing coil.
The technical program further can also be separately fixed at the including 2 or 4 translation coils, the translation coil
On two magnetites, put down in the move in plane perpendicular to optical axis, and relative two with the first magnetite interaction control lens mount
Move coil series connection or independently-powered.
Preferably, bottom is provided with metalwork, and the focusing coil is connected with motor external power source by metalwork.
The present invention replaces the spring in existing voice coil motor by the repulsive force between magnetite, reduces existing voice coil loudspeaker voice coil horse
Spring mechanism in reaching, enormously simplify the structure and reliability of voice coil motor, and making in the production process of voice coil motor will not be because
For spring is fragile or deformation and cause to produce fraction defective and improve, while the present invention greatly reduces the cost of motor, Neng Gouxian
Write the production efficiency and production yield for improving motor.
Description of the drawings

Specific embodiment
With reference to the accompanying drawings and examples invention is described in detail.It should be appreciated that the explanation to specific embodiment
Only to explain technical scheme proposed by the present invention, and the non-limiting present invention.
As shown in Figure 1 and Figure 2, the first embodiment of the present invention be an AF motors, 6 structure of yoke 4 and bottom of the AF motors
Into shell, the shell can strengthen internal magnetic field, and motor internal magnetic field and external magnetic field are separated, reduction external magnetic field
Interference to this motor internal magnetic field.Inside the shell is provided with lens mount, multiple first magnetites and multiple second magnetites.First magnetite is equal
Even distribution and it is fixed on movable lens mount 5, positioned at lens mount near one end of yoke, the second magnetite and the first magnetite are one by one
Relative misalignment, and be relatively uniformly fixed in yoke with the first magnetite polarity, such first magnetite 2 is subject to the second magnetite 1
Repulsive force, the first magnetite 2 is pressed on motor bottom bottom 6 by repulsive force together with movable part lens mount 5.The bottom of at
Focusing coil 3 is provided between lid 6, the first magnetite 2, coil 3 of focusing is fixed on the lower section of the second magnetite 1 in yoke, and by first
Magnetite 2 is non-contiguously trapped among in focusing coil, and metalwork can be arranged on bottom 6, and focusing coil 3 is by the metalwork and outside
Power supply connects.When coil 3 of focusing is powered, due to the magneticaction focused between coil 3 and the first magnetite 2, one can be produced
Prolong the active force of 5 optical axis direction of lens mount so that the first magnetite 2 prolongs the optical axis direction motion of lens mount 5 together with lens mount 5, from
And realize automatic focusing function.
As shown in Figures 3 to 5, the OIS motors of the second embodiment of the present invention are based on first embodiment, further
Extend its function so that motor can realize stabilization function in the move in plane perpendicular to optical axis.In this embodiment, put down
The quantity for moving coil 7 is 2 or 4, is separately fixed at the second magnetite 1 towards on the side of lens mount, itself and the first magnetite
Control lens mount interact in the move in plane perpendicular to optical axis, two relative coil-windings are in opposite direction and the two lines
Circle can be connected or independently-powered, and translation 7 place plane of coil controls to be mutually perpendicular to and all perpendicular to the optical axis institute of lens mount 5 respectively
In two free degree directions of plane.The electric current when translating coil 7 and having electric current to pass through, translation coil 7 can be produced to the first magnetite 2
One active force perpendicular to 5 optical axis place plane of lens mount so that the first magnetite 2 together with lens mount 5 perpendicular to light
Direction of principal axis place plane translation, so as to realize optical anti-vibration function.
The principle that the present invention is repelled each other using the magnetite same sex, a part of magnetite is fixed in yoke, another part magnetite
It is fixed on lens mount, two parts magnetite same sex is relative and staggers, and due to the repulsive force of two parts magnetite, lens mount is pressed in bottom
Cover.Coil is fixed with bottom simultaneously, coil is distributed in around the magnetite on lens mount, when the coil is energized, due to magnetic
The effect of field force so that the magnetite on lens mount is subject to the power along optical axis direction, promotes the magnetite band index glass on lens mount
Headstock is moved along optical axis direction.The present invention, by increasing coil in the outside of magnetite, and can control the electricity of different coils in addition
Stream so that be fixed on the magnetite on lens mount by the power perpendicular to lens mount optical axis place plane, drive lens mount vertical
In lens mount optical axis place plane translation, so as to realize the function of optical anti-vibration.
, only to illustrate structure of the invention, one of ordinary skill in the art is in the present invention for embodiments above
Design under can make various deformation and change, these deformation and change be included within protection scope of the present invention.
