[description of drawings]
Fig. 1 is the camera module diagrammatic cross-section that embodiments of the invention provide.
[embodiment]
Below in conjunction with accompanying drawing the present invention is described in further detail.
See also Fig. 1, be the camera module 100 that embodiments of the invention provide, it comprises 20, one sensitive chips 30 of 10, one lens set of a mirror head outer shell and is used to drive the lens driving apparatus 40 that described lens set 20 moves.
Described mirror head outer shell 10 is provided with an opening on the optical axis direction of described lens set 20, so that light can enter in the lens set 20.For preventing that dust and other impurities from entering in the camera module 100, in the present embodiment, a transparent panel 11 is set at described opening part.
In the present embodiment, described camera module 100 only comprises a lens set 20.This lens set 20 comprises one or more eyeglasses, and lens set described in the present embodiment 20 comprises two eyeglasses 21,22, and 21,22 on described two eyeglasses are provided with an aperture 23.
Described sensitive chip 30 is used to catch picture signal, and it can be charge-coupled image sensor or CMOS chips.For preventing that dust and other impurities from polluting sensitive chip 30, by a transparent panel 31 it is sealed in the present embodiment.
Described lens driving apparatus 40 comprises a CD-ROM drive motor, and preferably, this motor is a step motor, and described CD-ROM drive motor has stator 42 and rotor 41.Can move along optical axis direction simultaneously when having joggled structure that described rotor 41 is rotated between described rotor 41 and the stator 42.
Described joggled structure can be in described rotor 41 outsides and stator 42 inboards and is respectively equipped with the thread structure or the cam configuration that can cooperatively interact.Be to reduce the number of spare parts of using in the lens driving apparatus 40, preferably, the thread structure in described rotor 41 outsides or cam configuration and rotor are structure as a whole, and the thread structure of described stator 42 inboards or cam configuration and stator are structure as a whole.Described thread structure or cam configuration all can adopt the mode of ejection formation to form, and its material that adopts can be plastics.Described thread structure or cam configuration can improve the stability that lens barrel 411 moves when being organize more.In the present embodiment, described rotor 41 outsides and stator 42 inboards are respectively equipped with two groups of thread structure 41a and 42b that can cooperatively interact.So, when the rotor 41 of CD-ROM drive motor rotated, the thread structure 41a in its outside can rotate with respect to the thread structure 42b of stator 42 inboards, because stator 42 is motionless, thereby made rotor 41 when rotating, and moved along optical axis direction simultaneously.
Described stator 42 has a plurality of windings 421.This stator 42 is fixed on the mirror head outer shell 10, and fixed form can adopt adhesive securement or welding to fix, and in addition, described stator 42 also can be structure as a whole with mirror head outer shell 10.In the present embodiment, described stator 42 is fixed on the mirror head outer shell 10 by bonding agent 44.Described rotor 41 comprises a lens barrel 411 that is used for ccontaining lens set 20, which is provided with magnet 412.Described magnet 412 and lens barrel 411 can be structure as a whole, and specifically can be about to magnet 412 and be fixed in earlier in the shaping mould by the method for the embedded ejection formation of mould, inject the lens barrel material then and make it to form integrative-structure with magnet 412.
Described lens barrel 411 can further be provided with a focusing ring 43 at the end away from sensitive chip, is used for manual focusing, and can pass through the distance of this focusing ring 43 and mirror head outer shell 10, and the moving range of the distance limit lens barrel 411 of this focusing ring 43 and stator 42.
In addition, have the camera module of a plurality of lens set, can drive each lens set and move by a plurality of CD-ROM drive motor are set for some.Described stator 42 is used to produce a magnetic field, relies on magnetic force to drive rotor 41 and rotates, and therefore, the present invention also can adopt magnet 412 is set on stator 42, and winding 421 embodiments such as grade are set on rotor 41.
Described lens driving apparatus will be used for the lens barrel and the motor of ccontaining lens set to be integrated, simple in structure, has reduced the spare part that lens driving apparatus uses, thereby can reduce the volume of lens driving apparatus greatly.In addition, owing to because lens driving apparatus has reduced the quantity of the spare part that uses, can reduce manufacturing cost, the stability when improving lens driving apparatus work simultaneously.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
