Description
Technical field
This utility model relates to photographic goods accessory field, is specifically related to a kind of voice coil motor springs.
Background technology
Voice coil motor lamellar reed the most on the market is the most similar, but mostly not to operation
Time stress distribution and maximum conditions under stress distribution adjust, affect product run time stability and
Product reliability, particularly anti-dropping capability are poor.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is the sound providing a kind of stationarity high
Coil motor springs.
For solving the problems referred to above, the technical scheme that this utility model is used is as follows:
A kind of voice coil motor springs, including inner ring and outer ring, described inner ring and described outer ring concentric；
The inner circumferential of described inner ring is provided with at least 4 the first connecting holes, and described first connecting hole is ring with the center of inner ring
Shape array；The corner of described outer ring is equipped with the second connecting hole；Described inner ring and described outer ring are circuitous by 4
Return spring silk to be connected, the center circular array of inner ring described in described 4 roundabout spring filament windings.
As preferably, described roundabout spring silk includes the parallel-segment being parallel to each other a pair, connects this to parallel-segment
Arc section and with the extension that wherein a parallel-segment is connected；The angle of described extension and described parallel-segment in
Obtuse angle.
As preferably, corner, described outer ring is equipped with breach, and the centre of described indentation, there is provided with the 3rd connecting hole.
As preferably, described second connecting hole is arranged at the two ends of described breach.
As preferably, one end of each breach is at least provided with 2 the second connecting holes being parallel to each other.

Compared to existing technology, the beneficial effects of the utility model are:
The voice coil motor springs that this utility model provides has preferably stationarity, by inner ring
Connecting hole is set, the second connecting hole is set in outer ring, and connects inner ring and outer ring by roundabout spring silk, can
Stationarity when improving the anti-dropping capability of product and run.
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1；
In Fig. 1, each reference: 1, inner ring；11, the first connecting hole；2, outer ring；21, breach；
22, the second connecting hole；23, the 3rd connecting hole；3, roundabout spring silk；31, parallel-segment；32, arc section；

Detailed description of the invention
This utility model provides a kind of voice coil motor springs, and this springs is used for coupling voice coil motor
Upper gasket and the upper surface of lens supports body.
Embodiment 1
A kind of voice coil motor springs, as it is shown in figure 1, the inner ring 1 included and outer ring 2, described inner ring
Concentric with described outer ring；The inner circumferential of described inner ring is provided with 4 the first connecting holes 11, described first connecting hole with
The center circular array of inner ring；Described first connecting hole is used for being connected with the lens supports body of voice coil motor,
Its connected mode can be clamping or bonding；The corner of described outer ring is equipped with the second connecting hole 22, and described
Two connecting holes are for being connected with the Upper gasket of voice coil motor；Described inner ring and described outer ring are by 4 roundabout springs
Silk 3 is connected, the center circular array of inner ring described in described 4 roundabout spring filament windings.Described roundabout spring silk
Not only making this voice coil motor have higher pliability, this roundabout spring silk also can effectively ensure that described spring silk simultaneously
Stationarity, anti-dropping capability is good.
In the present embodiment 1, specifically, described roundabout spring silk includes the parallel-segment 31 being parallel to each other a pair, connects
Connect this to the arc section 32 of parallel-segment and with the extension 33 that wherein a parallel-segment is connected；Described extension with
The angle of described parallel-segment is in obtuse angle.So that this roundabout spring silk is when the plane upper and lower displacement of inner ring place, it is ensured that
The center of this inner ring is still within the lens axis of described voice coil motor；Even if or described roundabout spring silk is being subject to
To horizontal direction make power after, 4 spring silks of circular array can be cancelled out each other active force, so that this is interior
The center of circle is still within the lens axis of voice coil motor, i.e. this spring silk has preferable stability.
In the present embodiment 1, further, corner, described outer ring is equipped with breach 21, described indentation, there
Centre is provided with the 3rd connecting hole 23.Described 3rd connecting hole is for being connected with the Upper gasket of voice coil motor, and it is even
The mode of connecing can be clamping or bonding.Described outer ring can make springs with upper by the way of multiple spot is fixing
Pad connects more steady.Further, described second connecting hole is arranged at the two ends of described breach.Again
Further, one end of each breach at least provided with 2 the second connecting holes being parallel to each other, described second
Connecting hole be shaped as strip or waveform.With after ensureing that this outer ring and described Upper gasket are fixing and being connected stably
Be in connection plane in.
Above-mentioned embodiment is only preferred implementation of the present utility model, it is impossible to limit this practicality with this new
The scope of type protection, any unsubstantiality that those skilled in the art is done on the basis of this utility model
Change and replacement belong to this utility model scope required for protection.
