Applied to the autozoom and focusing of Zoom optic lens, existing stepper motor type of drive, rotating speed is low, and power consumption is high, easily by
Electromagnetic interference and noise effect, wear no resistance；Existing location sensitive mode uses opened loop control simultaneously, can only be sensed by PI
One position, control accuracy is low, the bad phenomenons such as step-out easily occurs；
Zoom optic lens stability in the market is poor, and big by magnetic field and noise effect, power consumption is high, easily grinds
The wild effects such as damage, step-out, it is impossible to meet present customer's more stringent requirement.
The present invention is researched and proposed for of the prior art not enough.
【The content of the invention】
The technical problem to be solved in the present invention is to provide a kind of Zoom optic lens, using piezo-electric motor type of drive and magnetic
Resistance sensor location sensitive mode fit applications are stable to realize that multiposition is detected in security protection Zoom optic lens.
In order to solve the above technical problems, present invention employs following technical proposals：A kind of Zoom optic lens, its feature exists
The moving parts of back and forth movement can be done in fixed cylinder and for driving in being provided with, including fixed cylinder, described fixed cylinder
Moving parts do the drive component of back and forth movement, and the drive component includes the screw mandrel and driving silk through the moving parts
The position detecting device for detector lens movement position is additionally provided with the piezo-electric motor that bar is rotated, the fixed cylinder, it is described
Position detecting device includes the magnetic resistance type sensor being arranged on moving parts and is oppositely arranged with magnetic resistance type sensor
Location sensitive magnetic sheet.
A kind of Zoom optic lens as described above, it is characterised in that the magnetic resistance type sensor is arranged on the fortune
The side of dynamic component, the location sensitive magnetic sheet is vertically arranged in the inwall of the fixed cylinder, and the location sensitive magnetic sheet with
The magnetic resistance type sensor correspondence is placed.
A kind of Zoom optic lens as described above, it is characterised in that be vertically arranged with the fixed cylinder for fortune
The guide shaft that dynamic component is oriented to.
Compared with prior art, a kind of Zoom optic lens of the invention, have reached following effect：
1st, the present invention is coordinated using the type of drive and magnetic resistance type sensing station induction mode of piezo-electric motor, by closing
Ring control system, improves the control accuracy of camera lens and the speed of motor, and below 1um position detection accuracy can be achieved；
2nd, the application that the type of drive of piezo-electric motor and magnetic resistance type sensing station induction mode coordinate, realizes multiposition
Sensing detection, accurate any one position for perceiving motor driving；
3rd, the application that the type of drive of piezo-electric motor and magnetic resistance type sensing station induction mode coordinate, realizes low noise
With magnetic field influence, durable small, the low function of power consumption of wearing and tearing of part solves the durable abrasion of Zoom optic lens, drives step-out, fortune
The problems such as dynamic noise, better meet the market demand and the higher and higher requirement of client.
