Description
Technical field
The present invention relates to a kind of piezoelectric optical lens, particularly a kind of by piezoelectric stator driving rotation of lens, reach the piezoelectric optical lens that furthers or zoom out function.
Background technology
Ultrasonic motor (or claim piezo-electric motor) but or piezo-activator applied in camera, digital camera or the camera cell phone, and be used for driving optical lens, make described optical lens have the effect that furthers or zoom out, become one of important technology of optical system or dependent merchandise.For example, the twin-core chip-type piezoelectric potsherd that utilizes of Britain 1Ltd. company (http://www.1limited.com) is made the piezo-activator of screw winding shape, described piezo-activator with can be used to be positioned over camera after optical mirror slip and support combine, but in digital camera or the camera cell phone as the image usefulness of focusing automatically, though it is little that the piezo-activator of described screw winding shape has a volume, the actuating displacement is big, low power consumption, silent and compatible advantages of higher, yet its shortcoming is, when twin-core chip-type piezoelectric potsherd was wound into the piezo-activator germule of screw winding shape, use was manually finished in a large number; Both having made is to utilize the robotization facility to finish, and also because its processing procedure difficulty is high and complicated, thereby the low and unsettled risk of quality of yield is arranged; Therefore but the piezo-activator of described screw winding shape is applied in camera, digital camera or the camera cell phone, and the usability on its industry is not high.
Moreover, in early days ultrasonic motor (or claim piezo-electric motor) or piezo-activator being applied in the traditional camera is a kind of existing technology, and relevant patent is also not within minority, for example U.S. Patent number 4755705,4786836,4829209,4935659,4952834,4959580,5013982 grades all are, because the traditional camera volume of early stage ccontaining film is bigger, so utilize existing apparatus such as above-mentioned ultrasonic motor (or claim piezo-electric motor) or piezo-activator or prior art is made optical lens or in order to drive optical lens, still be unlikely to cause too big problem, so digital camera replaces traditional camera gradually in recent years, and having the mobile lens that furthers or zoom out effect also spreads out and so becomes the commodity of fashion and become under the trend that the inevitable standard of mobile phone is equipped with, existing ultrasonic motor that above-mentioned build is big (or claim piezo-electric motor) or piezo-activator can't be again by ccontaining in it, but present visible digital camera or camera cell phone, the build of its optical lens module is very big still, mainly is still and continues to use existing apparatus or prior art.
But digital camera or camera cell phone as for piezoelectric optical lens with small size, though be found in relevant patent, paper or the symposial, yet, the member of described existing piezoelectric optical lens is quite complicated, relevant spare part can't utilize a batch Precision Machining to finish, and the processing beginning can be for it separately.
See also shown in Figure 1, No. the 6710950th, U.S.'s patent of invention " Piezoelectric actuator for digitalcamera optical system ", described case discloses a kind of existing piezoelectric optical lens structure, it mainly comprises a stay pipe 9, be provided with a lens barrel 10 in described stay pipe 9 inside, described lens barrel 10 is in order to the optical mirror slip (not shown) to be set, be provided with flexible electric circuit board 14 in described stay pipe 9 outer cover, the madial wall of described circuit board 14 extends axially and is provided with a plurality of piezo-activators 11 (only illustrating a group among the figure), outside described circuit board 14, coat one deck more elastic insulated 15, drive described lens barrel 10 by described piezo-activator 11, yet the disappearance of described structure is that the length of described lens barrel 10 is is what one turns to for guidance or support with the displacement, and it is bulky, circuit control is difficult for.
See also Fig. 2, No. the 6853507th, U.S.'s patent of invention " Lens driving device ", described case discloses a kind of optical mirror slip drive unit, it is to be provided with a pipe 7 in a bonnet 35, in described pipe 7, be provided with picture frame 3, described picture frame 3 is for optical mirror slip 1 is set, outside described pipe 7, be arranged with a sleeve 6, described pipe 7 and sleeve 6 have guide groove 6a respectively, 7a can be embedded in it for the projection 11 that described optical mirror slip 1 is had simultaneously, be provided with miniature gears 30 in described bonnet 35, the tooth 31 of described miniature gears 31 is to be embedded in described sleeve 6 bottoms, outside described miniature gears 30, coat a circle piezo-activator 10 again, drive described miniature gears 30 in regular turn by described piezo-activator 10, described sleeve 6 rotates, and then drives described optical mirror slip 1 and move axially in described pipe 7, yet the disappearance of described structure is, its structure is quite complicated, and the making difficulty of described miniature gears 30, simultaneously described piezo-activator 10 must polarize in segmentation, and very the eighteenth of the twenty is expensive for cost.
See also Fig. 3 again, the open case number No. 1020040078265 " Transfer unit; in whicha lens and an actuator are formed in one body " of Korean Patent, the disclosed optical mirror slip drive unit of described case is to be provided with guide rod 12, piezoelectric element 13 and back-up block 14 in a cylindric cover body 19 inside, the shortcoming of described structure is to need to add mass (mass), cause inertial force and move, cause described cylindric cover body 19 enlarged diameter, and weight increases.
Take a broad view of existing piezoelectric optical lens, its member is all quite complicated, except that increasing the degree of difficulty of making processing, its assembling mode is also quite complicated, particularly the assembling mode of piezoelectric stator quite is not easy, thereby the driving force of the piezoelectric optical lens that detracted, moreover, each tiny assembly can't utilize automaton to finish, also increased expending and manufacturing cost of manpower on foot, so, though described existing piezoelectric optical lens has the little advantage of volume, but on cost but without any competitive edge, so also do not have a usability on commercial value or the industry.
In sum, provide a kind of tool drive that torsion is big, volume is little, member is simple, firm in structure, easy to manufacture with assemble effects such as convenient, to solve above-mentioned listed shortcoming, and the piezoelectric optical lens drive unit of the usability on the tool industry, novelty and progressive, real problem for needing to be resolved hurrily.
