Embodiment
The utility model will coordinate embodiment and graphic being specified in down of enclosing.Should the person of understanding be that in the utility model, the embodiment of all only is the use of illustration, be not in order to restriction.Therefore the embodiment in literary composition, the utility model also can be widely used in other embodiment.And the utility model is not limited to any embodiment, should be with the claim of enclosing and equivalent fields thereof and decide.
The automatic focusing scene module structure that the utility model is dustproof, this modular structure is to utilize at the bottom of driving mechanism itself or its carrier (carrier) configuration one resilient material or compressible material, make the gap of this carrier and bracing frame (holder) close, fine particle (particle) can't be dropped out from the gap, fine particle with reduction or an anti-blocking part enters transparency carrier along the gap, and result has influence on the image quality of camera module.In other words, the modular structure of the utility model system utilizes a resilient material to be disposed at structural design between driving mechanism and bracing frame, can effectively reduce or anti-blocking fine particle further enters to transparency carrier along the slot between driving mechanism and housing, thereby the image quality of lifting image sensor, and make product line Yield lmproved.
Figure 1A shows the sectional view of an automatic focusing scene module structure.Automatic focusing scene module can be applied to the camera module of mobile phone.As shown in Figure 1A, wherein the automatic focusing scene module structure mainly comprises driving mechanism 100, lens 101, coil 102, magnet 103, bracing frame 104, transparency carrier 105, housing 106.The automatic focusing scene module structure also comprises printed circuit board (PCB) or flexible printed wiring board and image sensor (not graphic), and wherein image sensor is disposed under transparency carrier 105.The upper surface of image sensor have a sensing region and contact pad formed thereon.Housing 106 is used for coating the integral module structure.
Transparency carrier (or optical filter) 105 can be circular or square kenel.Transparency carrier 105 (or optical filter) can optionally be coated with infrared coating with the use as filtering, is used for the light wave of a certain wave band of filtration scioptics 101.
After the modular structure assembling is completed, between magnet 103 and driving mechanism 100 or coil 102, a space is arranged.That is driving fit and therebetween seam crossing has small gap fully between magnet 103 and driving mechanism 100 or coil 102.Therefore, the fine particle of a part can be mobile along the slot (sidewall) between magnet 103 and driving mechanism 100 or coil 102, and result stays between bracing frame 104 top and magnet 103 and driving mechanism 100 or coil 102, as shown in Figure 1A.
When coil 102 galvanization, based on the reciprocation between magnet 103 and coil 102, can drive driving mechanism 100 and a mobile distance 107 up, as shown in Figure 1B.For example, when seeing through automatic focusing scene module when burnt end far away (infinite side) is taken distant view, camera lens will just can be focused near bracing frame 104; And when seeing through automatic focusing scene module when nearly burnt end (macro side) is taken close shot, camera lens will just can be focused away from bracing frame 104.Therefore, in order to focus, driving mechanism 100 need to move around in the vertical direction of bracing frame 104.Driving mechanism 100 is driven lens 101 and is moved, make lens 101 near or be beneficial to focusing away from bracing frame 104.Up during a mobile distance 107, have a space between driving mechanism 100 and bracing frame 104 when driving mechanism 100.As a result, stay in above bracing frame 104 and the fine particle between magnet 103 and driving mechanism 100 or coil 102 can further move and enter transparency carrier 105 in above-mentioned space, and pollution transparency carrier 105 surfaces, as shown in Figure 1B.The lip-deep fine particle meeting of transparency carrier 105 remote effect arrive the image quality of the image sensor under it.In other words, in the modular structure of Figure 1B, the fine particle of a part may enter transparency carrier 105 along the slot (sidewall) between magnet 103 and driving mechanism 100 or coil 102, and fine particle will rest on above transparency carrier 105, and result has influence on light by the imaging on image sensor after transparency carrier 105.
From the foregoing, when utilizing automatic focusing scene module to take, when driving mechanism moves to nearly burnt end in burnt end far away, can produce the gap between driving mechanism 100 or its carrier and bracing frame 104, so particle or dirty meeting fall in the camera lens module structure, and cause the quality of image not good.
As shown in Fig. 2 A, show an embodiment of the automatic focusing scene module structure that the utility model is dustproof.In the present embodiment, dustproof automatic focusing scene module structure also comprises a resilient material (or compressibility material) 108, is disposed at the bottom of driving mechanism 100 itself or its carrier, or is disposed between driving mechanism 100 and bracing frame 104; Other structure division please refer to the narration that Figure 1A does.Resilient material 108 is disposed between driving mechanism 100 bottoms and bracing frame 104 upper surfaces.The configuration of resilient material 108 makes the bottom of driving mechanism 100 or its carrier and the clearance seal between bracing frame 104 upper surfaces, and allows fine particle can't pass through this gap, enters transparency carrier 105 with reduction or anti-blocking fine particle along this gap.In other words, the utility model automatic focusing scene module structure utilizes a resilient material 108 to be disposed at structural design between driving mechanism 100 and bracing frame 104, can effectively reduce or anti-blocking fine particle further enters to transparency carrier 105 along the slot between driving mechanism 100 and housing 106 (or magnet 103), thereby promote the image quality of image sensor.
When driving mechanism 100 up mobile one apart from the time, resilient material 108 also up extends thereupon.Due to the telescopic nature (or compressive characteristics of compressibility material) of resilient material 108, the space between driving mechanism 100 and bracing frame 104 is still that resilient material 108 is occupied, and can not produce a space, as shown in Fig. 2 B.Therefore, stay in above bracing frame 104 and the fine particle between magnet 103 and driving mechanism 100 or coil 102 still stays on back up pad 104, and tight can allow fine particle enter transparency carrier 105.
Comprehensively above-mentioned, configuration one resilient material on the bracing frame 104 of automatic focusing scene module structure; Utilize the characteristic of resilient material to be connected between bracing frame 104 and driving mechanism 100 or its carrier; When utilizing automatic focusing scene module to take, when driving mechanism 100 moves to nearly burnt end in burnt end far away, can not produce the gap between driving mechanism 100 or its carrier and bracing frame 104, thus particle or dirtyly can not fall in the camera lens module structure, thereby can promote the quality of image.
In the utility model automatic focusing scene module structure, fine particle will can not rest on above transparency carrier 105, thereby can exclude the possibility that particle affects image sensor.Fine particle recited above for example assembles with driving mechanism the dust that produces for external dust or lens.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; can expect easily changing or replacing, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
