It is following to disclose the embodiment or embodiment of subject technology scheme described in a variety of different implementations.For simplification
The specific example of each element and arrangement is described below in disclosure, and certainly, these are only example, is not to this
The protection scope of invention is limited.Such as the fisrt feature then recorded in the description above second feature or above
It is formed, may include the embodiment that the first and second features are formed by way of directly contacting, also be included in the first He
The embodiment that supplementary features are formed between second feature, to can not directly be contacted between the first and second features.In addition,
In these disclosures may in different examples repeat reference numerals and/or letter.The repetition is in order to brief and clear
Chu itself does not indicate each embodiment being discussed and/or interstructural relationship.Further, when first element be with
The mode that second element is connected or combines describes, which includes the reality that the first and second elements are connected directly or are bonded to each other
Mode is applied, also includes so that the first and second interelements ground connection is connected or is tied each other using one or more other intervening elements additions
It closes.In aftermentioned embodiment, the forward and backward optical axis to carry lens in mobile 3 is reference.In the case where without special instruction,
Axially refer to the optical axis direction, radially refers to the direction perpendicular to the optical axis direction.
As shown in Figure 1, driving device includes mobile 3, shell 2, pedestal 1, magnetite 5, coil 4, front side spring 7, rear side
Spring 6.
Mobile 3 is camera lens carrier or camera lens carrier carries camera lens or camera lens carrier and camera lens is integrally formed and ties
Structure, inner circumferential is circle and periphery is round or polygon.Shell 2 is usually made of magnetic material, including external annulus 21, end wall
22 and internal ring wall 23, external annulus 21 is continuous wall, and internal ring wall 23 is continuously or discontinuously wall body.It is fixed outer on pedestal 1
The external annulus 21 of shell 2.Multiple magnetites 5 are arranged on the inner circumferential side of external annulus 21 of shell 2.The outer of mobile 3 is arranged in coil 4
Zhou Shang.The outer periphery of front side spring 7 is fixed on shell 2, and inner periphery is fixed on the front side of lens carrier 3, rear side spring 6
Outer periphery is fixed on pedestal 1, and inner periphery is fixed on the rear side of lens carrier 3.After coil 4 is powered, generated between magnetite 5
Interaction force, the carry out activity accordingly of mobile 3, activity direction include the movement of optical axis direction or the shifting in vertical optical axis direction
It is dynamic.
With continued reference to Fig. 1, pedestal 1 has the dust-proof boss 12 of the dust-proof boss 11 of inner ring and outer ring, and mobile 3 has activity anti-
Dirt boss 13, the dust-proof boss 13 of activity is between the dust-proof boss 12 of the dust-proof boss 11 of inner ring and outer ring.
In embodiment shown in fig. 1, mover includes mobile 3 and coil 4 etc., and stator includes pedestal 1, shell 2, magnetic
Stone 5 etc..As shown in Fig. 2, mover and stationary part have hit bits, key strike occurs to hit in mover and shell 2, mover and bottom
Seat 1 is hit, and mover and magnetite 5 are hit.Clast 9 can accumulate near the dust-proof boss 12 in the outer ring on pedestal 1 after shock.Work as inversion
When driving device, clast 9 is moved along direction shown in arrow A in Fig. 2, difficult due to the blocking of the dust-proof boss 12 in outer ring
To enter between the dust-proof boss 12 in outer ring and the dust-proof boss 11 of inner ring, to will not be gathered on imaging sensor 8.
As shown in Fig. 2, the dust-proof boss 12 of space D 2, outer ring between the dust-proof boss 11 of inner ring and the dust-proof boss 13 of activity with
Space D 1 between the dust-proof boss 13 of activity is respectively greater than mobile 3 in the scope of activities perpendicular to optical axis direction.Due to being greater than
Scope of activities after mover mechanical position limitation in the horizontal direction, therefore can further avoid each anti-on carrier dust ring and pedestal
Dirt ring has hit bits.
In one embodiment, the dust-proof boss 12 in outer ring is multiple raised lines at interval.In another embodiment, outside
Enclosing dust-proof boss 12 is continuous annular.
In an embodiment not shown in the figure, mobile 3 have than the dust-proof boss 12 in outer ring also than lean on it is radially outer
Position has multiple shock boss in these positions, hits the radial outside that the dust-proof boss 12 in outer ring is arranged in boss.It will hit
Position the radial outside of the dust-proof boss 12 in outer ring is set, therefore to only occur in outer ring dust-proof due to hitting the dust generated
The radial outside of boss 12 will not enter between the dust-proof boss 12 in outer ring and the dust-proof boss 11 of inner ring, further prevent dirt
Bits enter on imaging sensor 8.
In an optional embodiment, 4 structure of coil that is carried on the inner peripheral surface of the dust-proof boss 12 in outer ring and mobile 3
At whole outer peripheral surface compare, radially more in the inner part.It is so had the technical effect that, when being gathered in the dust-proof boss in outer ring
When the dust of 12 peripheral sides is moved due to being inverted according to the direction arrow A as shown in Figure 2, dust will not be due to the stator shaft shoulder
Plane stops and enters between the dust-proof boss 12 in outer ring and the dust-proof boss 11 of inner ring, and then prevents dust from entering image sensing
Device 8.
As depicted in figs. 1 and 2, pedestal 1 also has planar portions 14, planar portions 14 in the radial outside of the dust-proof boss 12 in outer ring
Dust collecting space is limited with the dust-proof boss 12 in outer ring, dust 9 collects in the dust collecting space.The external annulus 21 and pedestal 1 of shell 2
Periphery wall contact and connected by way of bonding or others, therefore can further force dust 9 in the dust collecting space
Aggregation.
By aforementioned embodiments, it is also to be appreciated that a kind of photographic device, including camera lens, driving device and image pass
Sensor, driving device are driving device above-mentioned, and camera lens is arranged in mobile, and the optical axis side of pedestal is arranged in imaging sensor
To rear side.
