Description
Technical field
The utility model relates to a kind of voice coil motors of miniature webcam, and in particular to a kind of novel voice coil motor carrier.
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 2 and coiling loading end 3；Wherein, the bottom of pedestal is surrounded by multiple plastic rubber surfaces 4.The load of the existing design
Body is contacted using carrier base plastic rubber surface 4 with magnetite in terms of controlling voice coil motor stroke, in this way the depth of parallelism to each plastic rubber surface 4
And the requirement of appearance is very high, and needs Machining Arc face 5, 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.
In addition, current carrier mostly uses Central Symmetric to design, does not have to distinguish direction in this way in production and assembly, compare
It is convenient and efficient, but there is also following disadvantages：One, supplier is easy to mistake direction in coiling, causes former material bad；Two, exist
When putting carrier in production process, need manually to carry out the differentiation in direction, and due to the qualification difference of operator, work
The factors such as carelessness, and lack risk management, it is easy to so that carrier is put wrong direction, producing line is caused a large amount of defective products occur, increases life
Produce cost.
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
