Description
Technical field
The utility model relates to a kind of voice coil motors of miniature webcam, and in particular to a kind of impact-resistant voice coil motor load
Body.The miniature webcam can be assembled applied in the low profile electronics product such as mobile phone, tablet computer, smartwatch.
Background technique
In existing camera voice coil motor（VCM）In design, carrier is one of components of most critical.In the carrier
Equipped with upper lower through-hole, for assembling the eyeglass of camera；The carrier periphery is arranged with coil, in the yoke of motor described in correspondence
Coil is equipped with magnetite, constitutes when the coil is energized, and carrier can generate up and down direction displacement because of electromagnetic induction, takes the photograph to realize
Zoom, focusing as head；The top of the carrier or/and lower end surface there is also positioned elastic slice, for generating elasticity, guarantee 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 needs Machining Arc face 6, to increase the difficulty of mold processing, and in production process
Dispensing required precision it is very high；In addition, the structure based on the existing carrier designs, when voice coil motor is by external impacts, carry
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 class to be researched and solved of the utility model
Topic.
Summary of the invention
The purpose of the utility model is to provide a kind of impact-resistant voice coil motor carriers.
In order to achieve the above objectives, the technical solution adopted in the utility model is：
A kind of impact-resistant voice coil motor carrier, including a pedestal offer a through-hole in pedestal along the vertical direction, are used for
Assemble 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, leads to
Cross elastic slice on the one of bonding connection positioning voice coil motor；
Wherein, at least three strokes control convex block is additionally provided on the upper surface of the pedestal, each stroke controls convex block
It is uniformly distributed one support terrace of composition along the circumferencial direction of the through-hole, and the surface depth of parallelism of each stroke control convex block is consistent；
The stroke of carrier in above-below direction is limited and then against the shell of positioning voice coil motor.
Related content in above-mentioned technical proposal is explained as follows：
1. in above scheme, at least three strokes control convex block is uniformly distributed in circumferencial direction, a stable branch may make up
Support terrace.Since the area of support terrace is larger, and it is not necessarily to Machining Arc face, therefore more existing in the processing and production of mold
Technology 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 not
There is a problem of that viscose glue is bad.
2. in above scheme, each first glue groove is uniformly distributed in the upper surface along the circumferencial direction of the through-hole
On.
3. in above scheme, 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 above scheme, being convexly equipped with wrapping post outwardly on the lateral wall of the pedestal, the wrapping post is to position voice coil
The line end of motor coil.
The working principle and advantage of the utility model are as follows：
A kind of impact-resistant voice coil motor carrier of the utility model, including pedestal open up through-hole in pedestal for assembling mirror
Piece；Pedestal upper surface is equipped with multiple first glue groove, and bonding positions upper elastic slice；The upper surface of pedestal is equipped at least three strokes
Convex block is controlled, each stroke control convex block is uniformly distributed composition support terrace along the circumferencial direction of through-hole, and each stroke controls convex block
The surface depth of parallelism it is consistent；The stroke of carrier in above-below direction is limited and then against the shell of positioning voice coil motor.
Compared to existing technologies, the utility model controls convex block by least three strokes and uniformly divides in circumferencial direction
Cloth may make up a stable support terrace.Since the area of support terrace is larger, and it is not necessarily to Machining Arc face, therefore in mold
Processing and production when be easier to control compared with the prior art, and be not likely to produce bad order；In addition in the production of voice coil motor
Dispensing is not necessarily in journey herein, therefore the bad problem of viscose glue is not present.The carrier of the utility model is hit in voice coil motor by external force
When hitting, the area that carrier is impacted is larger, therefore the deformation after shock is smaller, can effectively promote the reliability of voice coil motor, make
Client can use with feeling more relieved.
