Abstract
The utility model discloses a kind of voice coil motor elastic slices, including two inside casings, two inside casings pass through spring silk and are connected with two outline borders, location hole there are four being all provided on two outline borders, location hole is total up to eight, convenient to connect with carrier, eight positioning pillars of setting on carrier, it can effectively ensure that elastic slice positioning accuracy by hole post cooperation, while guaranteeing that elastic slice does not rotate and causing properties of product bad；The inside middle position of two outline borders is equipped with a groove, and groove effect is that coil positive and negative anodes the end of a thread lineation avoids position, facilitates supplied materials lineation；Two spring silks are respectively provided between each outline border and inside casing, i.e., a total of eight spring silks, compared to four spring silks, eight spring silks can effectively improve life of product, promote the stability of product；Two waist-shaped holes are equipped on each outline border, it is ensured that positioning accuracy makes elastic slice not rotate inclination.
Description
Technical field
The utility model relates to voice coil motor technical fields, are especially a kind of voice coil motor elastic slice.
Background technique
Due to voice coil motor simple, small in size, low energy consumption, noiseless, high acceleration, fast response time, position with structure
The advantages such as shifting is accurate and price is low, so at present for camera automatic focusing device, voice coil motor structure automatic focusing
It is still the highest mode of cost performance.By the way that optical lens to be fixed on voice coil motor rotor coil holder, rotor is mobile as camera lens
Power unit, and voice coil motor rotor coil holder and stator are connected by elastic slice pair, after electrical power, rotor coil holder will be along mirror
Head optical axis direction moves in a straight line, to realize automatic focusing function, the effect of elastic slice pair be the driving of acceleration voice coil motor/
The pace of change of reduction.
However, the voice coil motor elastic slice of the prior art often there is problems in use: elastic slice inside casing with
Carrier position inaccurate, elastic slice are easy to happen rotation, cause product bad；Inconvenient coil positive and negative anodes the end of a thread lineation；Product
Stability is poor, and service life is low.
Utility model content
In view of the defect of the above-mentioned prior art, the purpose of this utility model is that: a kind of voice coil motor elastic slice is provided.
The technical solution of the utility model is: a kind of voice coil motor elastic slice, including two inside casings, two inside casings pass through spring
Silk is connected with two outline borders, is all provided on two outline borders there are four location hole, and the inside middle position of two outline borders is equipped with a groove；Often
Two spring silks are respectively provided between a outline border and inside casing；Two waist-shaped holes are equipped on each outline border.
Further, outline border is trapezoidal, and two waist-shaped holes are arranged at outline border both ends.
Further, every spring silk at least has seven arc sections.
Using a kind of voice coil motor elastic slice provided by the utility model, the beneficial effect is that:
It is all provided on two outline borders there are four location hole, location hole is total up to eight, conveniently connect with carrier, eight are arranged on carrier
A positioning pillar can effectively ensure that elastic slice positioning accuracy by hole post cooperation, while guarantee that elastic slice does not rotate and cause
Properties of product are bad；
The inside middle position of two outline borders is equipped with a groove, and groove effect is that coil positive and negative anodes the end of a thread lineation avoids position,
Facilitate supplied materials lineation；
Two spring silks are respectively provided between each outline border and inside casing, i.e., a total of eight spring silks, compared to four spring silks, eight springs
Silk can effectively improve life of product, promote the stability of product；
It is equipped with two waist-shaped holes on each outline border, can guarantee positioning accuracy when being attached with waist-shaped hole and other parts,
Elastic slice is set not rotate inclination.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
It is as shown in the figure: 1- inside casing, 2- outline border, 3- spring silk, 4- location hole, 5- groove, 6- waist-shaped hole.
Specific embodiment
For it is relatively intuitive, be fully understood by the technical solution of the utility model, now just combine the progress of the utility model attached drawing
Unrestricted feature description is as follows:
As shown in Figure 1, a kind of voice coil motor elastic slice, including two inside casings 1, two inside casings 1 are connected with two outline borders by spring silk 3
2, it is all provided with that there are four location holes 4 on two outline borders 2, and the inside middle position of two outline borders 2 is equipped with a groove 5；Each outline border 2 with
Two spring silks 3 are respectively provided between inside casing 1；Two waist-shaped holes 6 are equipped on each outline border 2.
Outline border 2 is trapezoidal, and two waist-shaped holes 6 are arranged at 2 both ends of outline border.
Every spring silk 3 at least has seven arc sections, can effectively ensure that 3 stress release of spring silk, improves the product itself service life.
A kind of voice coil motor elastic slice provided by the utility model, is all provided with that there are four location hole 4, location holes 4 on two outline borders 2
Eight are total up to, convenient to connect with carrier, eight positioning pillars of setting on carrier can effectively ensure that bullet by hole post cooperation
Piece positioning accuracy, while guaranteeing that elastic slice does not rotate and causing properties of product bad；The inside middle position of two outline borders 2 is equipped with
One groove 5, the effect of groove 5 are that coil positive and negative anodes the end of a thread lineation avoids position, facilitate supplied materials lineation；Between each outline border 2 and inside casing 1
Being respectively provided with two spring silks 3, i.e., a total of eight spring silks 3, compared to four spring silks 3, eight spring silks 3 can effectively improve life of product,
Promote the stability of product；It is equipped with two waist-shaped holes 6 on each outline border 2, is attached Shi Kebao with waist-shaped hole 6 and other parts
Positioning accuracy is demonstrate,proved, elastic slice is made not rotate inclination.
Certainly, the above is only the preferred embodiments of the present utility model only, and therefore, it does not limit the patents of the utility model
Range, all with the utility model specification and schema content institute, simply modification and equivalent structure change for it, should all similarly wrap
Within scope of patent protection contained in the utility model.
