Description
Technical field
The utility model relates to a kind of lens actuating device, refers to a kind of lens actuating device that can be applicable to minisize image acquisition module lens driving especially.
Background technology
In recent years, the trend that is equipped with image extraction module as the handheld apparatus of mobile phone, PDA etc. is more prevalent, and requirement better reaches under the littler market demand of volume to the hand-held apparatus function to be accompanied by produce market, and image extraction module has faced the more double requirements of high image quality and miniaturization.Lifting at the image extraction module image quality, be to improve pixel on the one hand, the trend in market is 30 pixels by former VGA grade, progressive up till now on the market common two mega pixels, three mega pixels, even released the above rank of eight more high-grade mega pixels.Except the lifting of pixel, be the sharpness of capture deeply concerned on the other hand, even so the image extraction module of handheld apparatus be optical zoom function development towards the automatic focus function of the optics of similar camera also by focusing the capture function.
The start principle of the automatic focus function of optics is according to the difference of subject matter far, closely, with the camera lens in the mobile image extraction module suitably, and then makes that the optical image of capture subject matter is focused on the image sensor exactly, to produce image clearly.Activate mode with at present general common movably to drive camera lens in image extraction module, it includes, and step motor activates, piezoelectric actuated and voice coil motor (VoiceCoil Motor, VCM) mode such as actuating.
In general, the mechanism of voice coil motor is seated in coil in the magnetic circuit that contains permanent magnet to constitute, thereby according to not coming bright left-hand rule, when conducting electricity, coil will produce interactive expulsive force with permanent magnet, to move the load bearing seat that connects permanent magnet, and then drive the lens assembly be fixed in the load bearing seat, and flow through the size of current of coil via adjustment, reach the purpose of optical zoom, focusing.
See also shown in Figure 1, promptly disclose out the shell fragment 1a of a lens driving apparatus for 2006-201525 number as TOHKEMY, it has an outer shroud circumference 11a, three inwalls from outer shroud circumference 11a extend the support arm 12a of bendingization continuously again, reaching one is located in the outer shroud circumference 11a and the interior ring circumference 13a that is connected with support arm 12a end, utilize the interior ring circumference 13a of this shell fragment 1a to be fixed in the lens assembly of lens driving apparatus, and outer shroud circumference 11a is fixed on the load bearing seat, and the purpose of locating/resetting to reach voice coil motor by the elastic force of shell fragment 1a.
Again as shown in Figure 2, also disclose the shell fragment 1b that a lens driving apparatus is arranged 2003-295033 number as TOHKEMY, its announcement has two symmetry classes to be the arc elastic arm 11b and a ring connector 12b of C type, after this shell fragment 1b is finished in punching press, arc elastic arm 11b each in one first location end 111b is crooked extend after again the reflexed bending extended to form an elastic arm 112b, and in its end be formed with second the location end 113b, ring connector 12b then connects two arc elastic arm 11b and is located.In addition, when installing, the first location end 111b of two arc elastic arm 11b and the second location end 113b are positioned respectively on lens assembly and the load bearing seat, ring connector 12b just can make two arc elastic arm 11b that the purpose that provides voice coil motor to locate/reset is provided after then need cutting off through one cut-out program.
Yet the shell fragment of above-mentioned two patent cases is driven by lens assembly and in vertical (axially) when direction moves, lens assembly easily produces to have a little and rotates, and then collides to shell fragment and make it that impaired situation be arranged, and finally may make shell fragment lose required effectiveness.
Secondly, shell fragment is via being stamped to form, but design form is when more complicated, as above-mentioned TOHKEMY 2006-201525 patent case, its support arm presents the form of continuous bending, promotes the problem for degree of difficulty, cost and the finished product yield etc. of diel development and Design.
In addition, above-mentioned TOHKEMY 2003-295033 patent case, its shell fragment then again need be through the action (promptly cutting off web member) of one blank after the blanking punching press is finished, and so, but increase process operations one, and then has the problem that increases cost man-hour etc.
In addition, please consult Fig. 3 and shown in Figure 4 again, also disclose out a lens driving apparatus 2008-026619 number as TOHKEMY, shell fragment 91a is located between shell 93a and the top skeleton frame 94a on it, the whole circle of the outer portion 911a of last shell fragment 91a is fixed between shell 93a and the top skeleton frame 94a, and the whole circle of the internal ring portion 912a that goes up shell fragment 91a is fixed on the lens mount 96a, with the purpose of locating/resetting as lens mount 96a.Following shell fragment 92a is located between underframe seat 95a and the lens mount 96a, it is outer and push down down the outer portion 921a of shell fragment 92a to be sheathed on lens mount 96a by an insulation ring plate 97a, shell fragment 92a is fixed on the underframe seat 95a, make that so but outer portion 921a and the internal ring portion 922a of shell fragment 92a are clamped down, do not have the flexible possibility of flexible.
In addition, the more important thing is, the wrist 913a of last shell fragment 91a connects inside and outside ring portion 911a, 912a, and the flexible elastic segments when relatively moving as outer portion 911a and internal ring portion 912a, but this wrist 913a is the design form of continuous bending, so make to make to be difficult for, and easy deformation is impaired.
Therefore, the above-mentioned amendatory defective of thoughts proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned defective.
