Equipped with upper lower through-hole, the eyeglass for assembling camera；The carrier periphery is arranged with coil, it is corresponding in the yoke of motor described in
Coil is equipped with magnetite, constitutes when the coil is energized, and carrier can generate upper and lower directions displacement because of electromagnetic induction, be taken the photograph to realize
Zoom, focusing as head；The top of the carrier or/and lower end surface there is also positioned shrapnel, for generating elasticity, ensure online
When enclosing no power, carrier can restore to initial horizontality position.
As shown in Figure 1, 2, the carrier of existing design includes cylindrical pedestal 1 at present, and the periphery of pedestal 1 corresponds to coil and is equipped with
Coiling dispensing portion 3 and coiling loading end 4；Wherein, the bottom of pedestal is surrounded by multiple plastic rubber surfaces 5.The load of the existing design
Body is contacted using carrier base plastic rubber surface 5 with magnetite in terms of controlling voice coil motor stroke, in this way the depth of parallelism to each plastic rubber surface 5
And the requirement of appearance is very high, and Machining Arc face 6 is needed, to increase the difficulty of mold processing, and in production process
Dispensing required precision it is very high；In addition, the structure design based on the existing carrier is carried when voice coil motor is by external impacts
The plastic rubber surface 5 of body is easy to deform because of the impact of external force, to reduce the reliability of voice coil motor.
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 impact-resistant voice coil motor carriers.
In order to achieve the above objectives, the technical solution adopted by the present invention is：
A kind of impact-resistant voice coil motor carrier, including a pedestal offer a through-hole in pedestal, for assembling along the vertical direction
The eyeglass of camera；
The upper surface of the pedestal is equipped with multiple first glue groove, and each first dispensing geosynclinal concave is set to the upper surface, by viscous
Close shrapnel on the one of connection positioning voice coil motor；
Wherein, at least three Stroke Control convex blocks are additionally provided on the upper surface of the pedestal, each Stroke Control convex block is along institute
The circumferencial direction for stating through-hole is uniformly distributed one support terrace of composition, and the surface depth of parallelism of each Stroke Control convex block is consistent；Pass through
Against the shell and then the stroke of restriction carrier in above-below direction of positioning voice coil motor.
Related content in above-mentioned technical proposal is explained as follows：
1. in said program, at least three Stroke Control convex blocks are uniformly distributed in circumferencial direction, the support day of a stabilization may make up
Face.Since the area of support terrace is larger, and it is not necessarily to Machining Arc face, therefore in the processing and production of mold compared with the prior art
It is easier to control, and is not likely to produce bad order；In addition it is not necessarily to dispensing herein in the production process of voice coil motor, therefore is not present
The bad problem of viscose glue.
2. in said program, each first glue groove is uniformly distributed in the upper surface along the circumferencial direction of the through-hole
On.
3. in said program, multiple anti-rotation blocks, each anti-rotation block phase are also convexly equipped on the lateral wall of the pedestal outwardly
Yoke positioning to voice coil motor, and each anti-rotation block is along the circumferential direction set to the surrounding of the pedestal；It designs whereby,
Further reinforcement can be played to the structural strength of carrier, more preferably protect carrier when voice coil motor is by external impacts, make
It is hardly damaged.
4. in said program, wrapping post is convexly equipped with outwardly on the lateral wall of the pedestal, the wrapping post is positioning voice coil
The line end of motor coil.
The operation principle and advantage of the present invention is as follows：
A kind of impact-resistant voice coil motor carrier of the present invention, including pedestal open up through-hole for assembling eyeglass in pedestal；On pedestal
End face is equipped with multiple first glue groove, the upper shrapnel of bonding positioning；The upper surface of pedestal is equipped at least three Stroke Control convex blocks,
Each Stroke Control convex block is uniformly distributed composition support terrace along the circumferencial direction of through-hole, and the surface of each Stroke Control convex block is parallel
Degree is consistent；The stroke of carrier in above-below direction is limited by against the shell of positioning voice coil motor.
Compared to existing technologies, the present invention is uniformly distributed by least three Stroke Control convex blocks in circumferencial direction, can
Constitute a support terrace stablized.Since the area of support terrace is larger, and it is not necessarily to Machining Arc face, therefore in the processing of mold
And be easier to control compared with the prior art when production, and it is not likely to produce bad order；In addition in the production process of voice coil motor this
Place is not necessarily to dispensing, therefore there is no the bad problems of viscose glue.The present invention carrier when voice coil motor is by external force collision, carrier by
The area of shock is larger, therefore the deformation after shock is smaller, can effectively promote the reliability of voice coil motor, enable a customer to more
Relievedly use.

Specific implementation mode
The invention will be further described with reference to the accompanying drawings and embodiments：
Embodiment：Shown in attached drawing 3,4, a kind of impact-resistant voice coil motor carrier, an including pedestal 7, in pedestal 7 vertically
Direction offers a through-hole 8, the eyeglass for assembling camera；
The upper surface 9 of the pedestal 7 is equipped with multiple first glue groove 10, and each first glue groove 10 is recessed in the upper surface 9,
By bonding shrapnel on connect positioning voice coil motor one（It is not drawn in figure）；Each first glue groove 10 is along the through-hole 8
Circumferencial direction be uniformly distributed on the upper surface 9.
Wherein, at least three are additionally provided on the upper surface 9 of the pedestal 7（Such as four）Stroke Control convex block 14, it is each described
Stroke Control convex block 14 is uniformly distributed one support terrace of composition, and each Stroke Control convex block 14 along the circumferencial direction of the through-hole 8
The surface depth of parallelism it is consistent；Pass through the shell against positioning voice coil motor（Yoke）And then limit the row of carrier in above-below direction
Journey.
Wherein, four Stroke Control convex blocks 14 constitute a support terrace stablized.Since the area of support terrace is larger, and
It without Machining Arc face, therefore is easier to control compared with the prior art in the processing and production of mold, and is not likely to produce appearance not
It is good；In addition it is not necessarily to dispensing herein in the production process of voice coil motor, therefore there is no the bad problems of viscose glue.
Multiple anti-rotation blocks 16 are also convexly equipped on the lateral wall 15 of the pedestal 7 outwardly, each anti-rotation block 16 is with respect to voice coil
The yoke of motor positions, and each anti-rotation block 16 is along the circumferential direction set to the surrounding of the pedestal 7.It designs whereby, it can
Further reinforcement is played with the structural strength to carrier, carrier is more preferably protected when voice coil motor is by external impacts, makes it
It is hardly damaged.
It is convexly equipped with wrapping post 18 outwardly on the lateral wall 15 of the pedestal 7, the wrapping post 18 is positioning voice coil motor line
The line end of circle.
Compared to existing technologies, carrier of the invention is when voice coil motor is by external force collision, the face that carrier is impacted
Product is larger, therefore the deformation after shock is smaller, can effectively promote the reliability of voice coil motor, enable a customer to make with feeling more relieved
With.
