Description
Technical field
The present invention relates to voice coil motor.
Background technology
At present along with the development of smart mobile phone, the requirement of people to the function of smart mobile phone is also more and more higher, especially the camera function of smart mobile phone, and people expect that the effect of taking pictures of smart mobile phone can reach the level of digital camera.And the volume of digital camera is comparatively large, the mechanical structure of relative complex can be held to control the multi-dimensional movement of camera lens, therefore, it is possible to realize optical anti-vibration (OIS) and move the technology that axle photographs.But smart mobile phone is for digital camera, not only volume is little, and the thickness of smart mobile phone be only digital camera 1/4th or thinner, therefore, it is very restricted that the voice coil motor being applicable to smart mobile phone will realize various function, the voice coil motor amount of each manufacturers produce of smart mobile phone or complex structure, oversize, the growth requirement that smart mobile phone is frivolous cannot be adapted to, or be functionally short of to some extent, or there is high cost, volume production difficulty is large, produces the problems such as yield is not high.
Summary of the invention
The present invention is in order to solve the technical problem existed in above-mentioned prior art, a kind of voice coil motor being realized optical anti-vibration by translational motion is proposed, comprise the shell that bottom becomes with outer metallic magnetic yoke piece, be located at the interior metal yoke in shell, by the lens mount that spring leaf is connected with described bottom, be fixed on the focusing coil of lens mount periphery, be fixed on the magnetite on interior metal yoke inwall, described focusing coil and magnetite interact the focusing parts forming and control lens mount and carry out focusing, also comprise translation coil, described translation coil pair and magnetite interact, control focusing parts at the move in plane perpendicular to optical axis.
Concrete syndeton of the present invention is: described magnetite is provided with four, and four magnetite correspondence focusing coils is interior pendant polar identical, described translation coil is being provided with four perpendicular in the plane of optical axis accordingly with magnetite position, described spring leaf comprise from the inside to the outside connect respectively by spring wire inner segment, stage casing and outer section, the plane at the spring wire place between described stage casing with outer section is parallel with optical axis, described inner segment and lens mount are fixed, and stage casing and magnetite are fixed, and fix for outer section with shell.
In the present embodiment, four translation coils can be separate, or two the translation coils be positioned on diagonal can also series connection mutually.
The end face of the described lens mount of the present embodiment is octagon.
The present invention is directed to the different shortcomings of each the voice coil motor produced at present, have developed the voice coil motor being realized stabilization kinetic energy by translational motion, not only can realize focusing, the stabilization function of camera lens, and parts of the present invention are less, Total Product volume is little, production yield is high, low in energy consumption, volume production preferably.
Accompanying drawing explanation
Fig. 1 is the explosive view of one embodiment of the invention;
Fig. 2 is the cutaway view of one embodiment of the invention.
Embodiment
Specific embodiments of the invention are described in detail below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 2, voice coil motor of the present invention comprises bottom 8, interior metal yoke 3, outer metal yoke 1, four magnetites 2, lens mount 5, focusing coil 4, four translation coils 6 that camera lens is housed and spring leaf 7.
Bottom 8 and outer metal yoke 1 form shell, interior metal yoke 3 arranges in the enclosure, lens mount 5 is arranged in interior metal yoke 3, camera lens is coaxially arranged in lens mount 5, the end face of lens mount 5 is octagon, focusing coil 4 is fixed on the periphery of lens mount 5, four magnetites are fixed on the inwall of interior metal yoke 3 evenly and at intervals, non-conterminous four sides are relative mutually with focusing coil 4 respectively, and the interior pendant polar homogeneous phase of magnetite 2 correspondence focusing coil 4 is same, interior metal yoke 3 can shield inner and outer magnetic field, guarantees the normal work of voice coil motor.
Spring leaf 7 comprise from the inside to the outside connect respectively by spring wire inner segment, stage casing and outer section, other parts of plane spring sheet at the spring wire place wherein between stage casing and outer section are perpendicular, the plane at its place is parallel with optical axis, inner segment and lens mount are fixed, stage casing and magnetite are fixed, and outer section is fixed on bottom 8.Four translation coils 6 are fixed on the corner of bottom, are positioned at immediately below four magnetites 2, and wherein two, diagonal angle coil can be connected, or four coils are separate, and four translation coil 6 place plane orthogonal are in optical axis.
When coil 4 of focusing is energized, magnetite 2 pairs of lens mounts 5 produce the active force of a parallel optical axis, and lens mount 5 is moved forward and backward along optical axis direction.Therefore, coil 4 of focusing forms with magnetite 2 the focusing parts controlling lens mount 5 and carry out focusing.When translation coil 6 is energized, because the plane at the spring wire place between the outside of spring leaf 7 and middle part is parallel with optical axis, therefore translation coil 6 can to the active force of focusing parts generation perpendicular to optical axis place plane, under the acting in conjunction at and middle part outside at spring leaf, control focusing parts at the move in plane perpendicular to optical axis place, because magnetite 2 and interior metal yoke 3 interfix, focusing coil 4 interfixes with lens mount 5 and camera lens, therefore, the interaction of translation coil 6 and magnetite 2, interior metal yoke 3 and all parts in it can be made together at the move in plane perpendicular to optical axis.
As mentioned above, the present invention, by four magnetites around five fitting coils installings and coil, achieves the focusing to camera lens and controlled translation, and this whole mechanism volume is little, be easy to match with drive circuit, structure is simple, meets the lightening growth requirement of smart mobile phone.
Above specific embodiment is only in order to illustrate design of the present invention, and those of ordinary skill in the art can make various deformation and change under design of the present invention, and these distortion and change include within protection scope of the present invention.
