Body is fixed together, and is placed in stator interior, and the carrier is together with coil along center side inside the iron-clad and magnetite of stator
It further include upper elastic slice and lower elastic slice to the lens driver is moved forwards, backwards, their peripheries are fixedly connected and consolidate with iron-clad
Determine carrier, the precompressed elastic force that the electromagnetic force that coil generates after being powered overcomes upper elastic slice and lower elastic slice to generate drives carrier along optical axis
Direction is mobile.
This autofocus motor, structure mainly carry out positioning and guiding by shell, and structure is complicated, part is more, thrust
It is small, Z-direction is thick, the assembly process is complicated and is easy to appear defect ware, and common focus function only can be achieved in function, is unable to satisfy and pushes away greatly
Power, the ultra-thin market demand.
The content of present invention
The technical problem to be solved by the present invention is to provide ultra-thin one kind, high thrust, reduction production cost and space
A kind of ultra-thin high thrust autofocus motor of effective use.
In order to solve the above-mentioned technical problem, the technical solution of the invention is as follows:
A kind of ultra-thin high thrust autofocus motor, including, pedestal, lower elastic slice, carrier；Pedestal is integrally formed insertion
Metal terminal；Metal terminal is connected with external circuitry；Pedestal is equipped with lower elastic slice；Carrier and the compressing of lower elastic slice connect, with pedestal
Clamping；Coil one and coil two are arranged on carrier two sides；It is covered with iron-clad on pedestal, magnet one, magnet are provided in iron-clad
Two, magnet three, magnet four realize that magnet and coil cutting connect.
The invention has the advantages that the simple focusing motor of ultra-thin, high thrust, structure.It can effectively solve the thickness that market faces
Bottleneck high, that thrust is small, while save the cost are spent, mould set product space shared in mobile phone is effectively saved, is following high
Pixel, ultra thin handset trend are taken a firm foundation.Can effectively solve the bottleneck of thickness, thrust that market faces, at the same save at
This, effectively saves mould set product space shared in mobile phone, takes a firm foundation for the following high pixel, ultra thin handset trend.
