The invention discloses a kind of camera autofocus motor shell fragment, it is characterized in that, circular shell fragment inner ring including square shell fragment outer ring and inside shell fragment outer ring, the diameter of shell fragment inner ring is less than the length of side of shell fragment outer ring, shell fragment outer ring is longitudinally divided into symmetrical split-type structural along center line, shell fragment inner ring is laterally divided into split-type structural symmetrical above and below along center line, it is chamfering at the corner of shell fragment outer ring, shape identical connecting portion is provided with four chamferings of shell fragment outer ring between shell fragment inner ring, the connecting portion is provided with respectively in the left and right sides to the U-shaped opening of depression at center.The structure of the present invention is simple, and each connecting portion disperses shell fragment uniform force, improves the stability of shell fragment, prevents from, because external force reason causes the slight movement of shell fragment position, improving shooting quality and shooting effect.
Description
Technical field
The present invention relates to mobile phone camera autofocus motor technical field, and in particular to a kind of camera auto-focusing horse
Up to using shell fragment.
Background technology
Mobile phone camera widely realizes automatic focusing function using VCM motor, and the position of camera lens can be adjusted by motor
Put, clearly image is presented.The autofocus motor used in mobile phone camera is mainly made up of coil, group of magnets and shell fragment,
Coil is fixed in group of magnets by upper and lower two shell fragments, and when the coil is energized, coil produces magnetic field, coil magnetic field and group of magnets
Interaction, coil moves up, and the camera being locked in coil moves together therewith, and during power-off, coil is made in shell fragment elastic force
With lower return, automatic focusing function is realized.
With making rapid progress for mobile phone application technology, requirement of the cellphone subscriber to cell-phone camera also more and more higher therewith, from
Dynamic focusing motor shell fragment plays vital effect in Mobile phone automatic focusing.Shell fragment is very high to requirement on machining accuracy simultaneously,
The dimensional tolerance of shell fragment elater is smaller, and the effect of auto-focusing is better.
Mobile phone camera autofocus motor shell fragment of the prior art in use can due to unreasonable structure
Shell fragment unbalance stress is caused, causes voice coil motor position of camera lens during auto-focusing inaccurate, causes a deviation, influence to clap
Take the photograph effect.
The content of the invention
It is an object of the invention to overcome deficiency of the prior art, there is provided a kind of camera autofocus motor bullet
Piece, simple in construction, non-deformability is good.
In order to solve the above technical problems, the invention provides a kind of camera autofocus motor shell fragment, it is characterized in that,
Circular shell fragment inner ring including square shell fragment outer ring and inside shell fragment outer ring, the diameter of shell fragment inner ring are less than shell fragment outer ring
The length of side, shell fragment outer ring are longitudinally divided into symmetrical split-type structural along center line, and shell fragment inner ring is laterally divided into along center line
Symmetrical split-type structural down, is chamfering at the corner of shell fragment outer ring, at four chamferings of shell fragment outer ring between shell fragment inner ring
Provided with shape identical connecting portion, the connecting portion is provided with respectively in the left and right sides to the U-shaped opening of depression at center.
Preferably, the connecting portion is the symmetrical structure using shell fragment outer ring diagonal as center line.
Preferably, waist-shaped hole is provided with the center of the connecting portion.
Preferably, triangle open-work is additionally provided with left and right sides of waist-shaped hole.
Preferably, the connecting portion, shell fragment inner ring and shell fragment outer ring are respectively positioned in same horizontal plane.
Preferably, the shell fragment is produced using photochemical etching technique.
Preferably, the shell fragment is made of MAX215 copper alloys, and integral rigidity is strong, and impact resistance is good.
Compared with prior art, the beneficial effect that is reached of the present invention is：The structure of the present invention is simple, and each connecting portion will
Shell fragment uniform force is disperseed, and improves the stability of shell fragment, prevents from, because external force reason causes the slight movement of shell fragment position, carrying
High shooting quality and shooting effect.
Brief description of the drawings
Fig. 1 is the structural representation of shell fragment of the present invention.
Reference：1st, shell fragment outer ring；2nd, shell fragment inner ring；3rd, it is open；4th, waist-shaped hole；5th, open-work.
