Description
Technical field
The present invention relates to a kind of voice coil motors of miniature webcam, and in particular to a kind of voice coil motor of new function.It is described
Miniature webcam can be assembled applied in the low profile electronics product such as mobile phone, tablet computer, smartwatch.
Background technology
In existing camera voice coil motor（VCM）In design, structure generally includes a carrier, is positioned at the yoke of motor
In iron.Upper lower through-hole, the eyeglass for assembling camera are equipped in the carrier；Wherein, the periphery of pedestal is arranged with coil, horse
The coil is corresponded in the yoke reached and is equipped with magnetite, is constituted when the coil is energized, and carrier can generate up and down because of electromagnetic induction
Direction displacement, to realize zoom, the focusing of camera；The top of the carrier or/and lower end surface there is also positioned shrapnel, use
In generating elasticity, ensure in coil no power, carrier can restore to initial horizontality position.
Currently, the coil of voice coil motor is after powered up, meeting monodisplacement a distance under the action of electromagnetic force reaches tune
The purpose of whole lens focus understands picture and meets the requirement of user to find suitable position and take.However, existing voice coil
Motor is only capable of doing one-way movement under the action of electromagnetic force, therefore can only adjust nearly coke, and can not adjust remote coke, and focusing time
It is longer.
In addition, in the design of existing voice coil motor, as shown in Figure 1, the form that yoke 1 and lower cover 2 are matched using loading and unloading,
In order to be attached and position with yoke 1, four weekly assemblies of lower cover 2 open up four clamp bar slots 3 respectively, four cards with 1 bottom of yoke
4 grafting of block is combined.The prior art the problem is that, the combination part of yoke 1 and lower cover 2 using external four side seal glue side
Formula is fixed, and the plastic cement area reserved on lower cover 2 is smaller, can both influence to draw glue when Client Enterprise carries out follow-up module group assembling in this way
Position size, and it is be easy to cause degumming, it is also easy to cause housing bottom excessive glue, makes dispensing out-of-flatness, to voice coil motor product
Appearance causes harmful effect.
Therefore, above-mentioned the shortcomings of the prior art how is solved, is become as the project of the invention to be researched and solved.
Invention content
The object of the present invention is to provide a kind of voice coil motors of new function.
In order to achieve the above objectives, the technical solution adopted by the present invention is：
A kind of voice coil motor of new function is assembled by the first assembly and the second assembly and is positioned in above-below direction；
First assembly includes yoke, magnetite and upper shrapnel；The magnetite is fixedly arranged in the circumferential inside the yoke,

Second assembly includes carrier, coil, lower shrapnel and lower cover；The carrier includes a pedestal, along upper in pedestal
Lower direction offers a first through hole, the eyeglass for assembling camera；Described in the upper surface bonding connection positioning of the pedestal
Second elastic tip of upper shrapnel；The lower face bonding connection of the pedestal positions the first elastic tip of the lower shrapnel, lower shrapnel
The second elastic tip be then positioned at the top of the lower cover；The periphery of the pedestal is arranged with coil, the coil and is positioned at institute
The magnetite stated in yoke is correspondingly arranged；Also, when the coil is not powered on, the upper shrapnel and the lower shrapnel are equal
Planar deformation may be not present in horizontal；
The yoke is positioned with lower cover assembly, defines to form an assembly space between the two；The carrier is existed by two shrapnels
It is flexibly positioned in the assembly space on the thickness direction of voice coil motor；Wherein,
The yoke is made of a rectangular-shaped top plate and four side plates；One second through-hole is offered in the middle part of the rectangular-shaped top plate, it should
Second through-hole is coaxially disposed with the first through hole；Four side plates are integrally extended along its four edges respectively by the rectangular-shaped top plate
It bends downward to be formed；
The lower cover includes the flat lid of a rectangle, offers a third through-hole in the middle part of the flat lid, the third
Through-hole is coaxially disposed with second through-hole；Wherein, the surrounding recess of the lower cap upper surface, forms rectangular ring positioning
Slot, the yoke are inserted into the bottom of its four side plate in the cyclic annular locating slot, and the inside fitting of each side plate
The cell wall of the ring-type locating slot, reaches the assembly of the yoke and the lower cover；
Each side plate is connect by viscose with the binding site of the cyclic annular locating slot, reaches the yoke and the lower cover
Positioning.
Related content in above-mentioned technical proposal is explained as follows：
1. in said program, by the combination assembling form of the first assembly and this two assembly of the second assembly, can be improved
The efficiency of assembling of voice coil motor and the yields for improving product.
2. in said program, " when the coil is not powered on, the upper shrapnel and the lower shrapnel are in horizontal put down
Deformation may be not present in planar ", therefore shrapnel is without precompression, it, can be upward by the effect of electromagnetic force on the one hand after motor energization
Or move downward, another aspect motor is not necessarily to that the precompression of shrapnel is overcome to do work during exercise, so as to reach rapid focus
Effect.
3. in said program, the contact site of the lower face of the pedestal and the first elastic tip of the lower shrapnel is plane,
There is no the structures that such as boss makes lower shrapnel generation predeformation in this way.
4. in said program, there is a gap between the magnetite and the lower shrapnel.
5. in said program, the binding site includes the slot bottom of the bottom and the cyclic annular locating slot of each side plate
Contact position further includes the contact position of the inside and the cell wall of the cyclic annular locating slot of each side plate.
6. in said program, the ring-type locating slot is located at the outer most edge of the lower cap upper surface, ring-type positioning is constituted
Slot only includes the cell wall of side inwardly.
The operation principle and advantage of the present invention is as follows：
Compared to existing technologies, of the invention：
One, by designing a novel voice coil motor, shrapnel on the one hand after motor energization, can pass through electromagnetism without precompression
The effect of power is moved upwardly or downwardly, and another aspect motor is not necessarily to that the precompression of shrapnel is overcome to do work during exercise, so as to
Achieve the effect that rapid focus.The requirement for preferably meeting user improves the use feeling of user, and more power saving, prolongs
The stand-by time of equipment is grown；
Two, the sealing mode of yoke and lower cover is changed to internal sealing, there is an advantage in that：1, module can effectively be increased
Viscose area when assembling increases module and pushes and pulls pull out force, increases Client Enterprise production yield, meets Client Enterprise push-and-pull pull out force need
It asks；2, the production procedure that can simplify voice coil motor, the direct dispensing before yoke, lower cover assembling do not have to carry out because of finished product sealing
It is secondary to turn over；3, the bad orders problems such as the bottom excessive glue of voice coil motor will not be caused in process of production.
