Description
Technical field
This novel novel pair of Magnetitum of one that relate to drives the two poles of the earth automatic focusing mechanism, belongs to electromagnetic technology field.
Background technology
Automatic focusing mechanism is mainly voice coil motor, and in the magnetic field that voice coil motor is a kind of utilization to be produced from the magnetic field of permanent-magnet steel and hot-wire coil conductor, interacting between magnetic pole produces the device of regular motion, is widely used in mobile phone camera.Current all of driving means all uses iron-clad as stator skeleton, form the magnetic field closed；The magnetic conductivity of irony is preferable, but the antenna side of mobile phone terminal typically it is assembled in due to automatic focusing mechanism, antenna is also an electromagnetic component, when antenna works simultaneously, when the magnetic field of antenna also reaches the strongest, existence due to iron-clad stator, there is a certain degree of interference in both magnetic fields, the function causing two electromagnetic fields is affected, make antenna, when the signal received is converted into sound, noise occur, or bad deviation occur during the signal phenomenon, and camera focusing such as off and on, both are seriously restricted by Function.It addition, in current automatic focusing mechanism, drive magnet is the most all integrally fixed at iron-clad inwall, location and assembly technology are required height, it is not easy to the later stage is modified and function adjustment.
It addition, current automatic focusing mechanism volume is more and more less and precision is the most more come the highest, it is therefore desirable to a kind of new type auto focusing mechanism that can reduce volume and dust-proof effect.
Novel content
In order to overcome drawbacks described above, a kind of novel pair of Magnetitum of this novel offer drives the two poles of the earth automatic focusing mechanism.
nullTo achieve these goals，This novel technical scheme is: a kind of novel pair of Magnetitum drives the two poles of the earth automatic focusing mechanism，Including front baffle、Drive Magnetitum、Drive coil、Lens supports body、Base，Described driving coil is arranged on the external wall of lens supports，Drive Magnetitum and be correspondingly arranged with driving coil，Front baffle is combined formation cavity with base，Lens supports body、Drive Magnetitum、It is placed in cavity，Described edge, base four limit is outer low and inner high limit of getting out of a predicament or an embarrassing situation，Edge, front baffle four limit is high outside and low outside limit of topping bar，Front baffle and base are by upper、Get out of a predicament or an embarrassing situation the embedding connection in checkpost，Four angles of front baffle are provided with downward opening recess hole，Base corner is provided with the projection matched with recess hole，Described driving Magnetitum is divided into Magnetitum and lower Magnetitum，Upper Magnetitum and lower Magnetitum are distributed up and down，The magnetic pole of upper Magnetitum and lower Magnetitum is for being reversed.
Further, described front baffle is that plastics are made and integrated injection molding.
Further, the limit of topping bar of get out of a predicament or an embarrassing situation limit and the front baffle of described base is multi-stage stairs limit.
Basis is the most novel to be provided the benefit that: 1, use double Magnetitum drive pattern, Magnetitum magnetizing direction is relative up and down, it is effectively formed continuous print magnetic field space, guarantee the magnetic field homogeneity at Movement in Magnetic Field center, and there is enough magnetic field intensities, coordinate integrated two lateral coils, it is provided that more effectively drive power；Volume can be effectively reduced under equal driving force；2, front baffle and base use multi-stage stairs checkpost setting-in to join, and dust-proof effect is more preferable；3, front baffle uses integrally moulded, can effectively prevent electromagnetic interference.
