Description
Technical field
The utility model relates to the technical field of drive motor, specifically a kind of monofilament reed structure for lens drive motor, particularly the spring silk structure of its reed.
Background technique
Along with the functional diversities of digital product, be equipped with the digital equipment of vidicon camera or photographic camera, as mobile phone, multimedia player etc., obtain high speed development and extensive use.Above-mentioned vidicon camera or photographic camera, can adopt the camera lens of focus adjustable or auto-focusing usually, and the process regulated is then the position changing camera lens, normally uses drive motor for driving lens moving.
In order to adapt to the requirement of photographic camera miniaturization, adopt a kind of drive unit utilizing magnetic field to produce power more and more.Be in the scheme disclosed in a kind of lens driver of ZL200410017724.3 in Chinese utility model patent number, comprise one and be arranged on tubular magnet yoke ring on base, be mounted with magnetite and coil in this magnet yoke ring, this coil inner circumferential side is provided with the lens of band lens supports body, it is inner that described magnetite and coil are placed in this magnet yoke ring, this coil is fixed on the periphery of lens supports body of this magnet yoke ring inner circumferential side, this lens supports body stretches in described tubular magnet yoke ring and also can move in this magnet yoke ring, described lens driver also comprises front side reed and the rear side reed of annular, their outer circumferential side end is fixedly connected with the front side of described magnet yoke ring, also has a small cap, described front side reed inner peripheral side end portion is fixed on on front side of described lens supports body by this small cap, also has a framework, this framework by described front side reed outer circumferential side end winding support on the front side of described magnet yoke ring.
Said lens drive unit utilizes the electromagnetic induction effect of magnetite, make the lens supports body be placed in the middle of magnet yoke ring be subject to parallel electromagnetic force and produce displacement, the front side reed and the rear side reed that are placed in lens supports body produce reaction force simultaneously, when the electromagnetic force acted on lens supports body and reed elastic force reach balance, this lens supports body remains on certain position; Namely the electromagnetic force produced after described coil electricity resists the active force in described front side reed and rear side reed mutually, orders about described lens supports body and moves to bearing of optical axis.
Although existing lens driver can be moved by both sides reed restriction lens supports body before and after it, make it to have resistance to jolting with impact property and the good image quality of tool.But find that the driving force of this lens driver is strong not in actual use, the coefficient of stability is not high.
Summary of the invention
The purpose of this utility model is to provide a kind of monofilament reed structure for lens drive motor, effectively improves the combination property of drive motor, the stability especially during motor operation.
To achieve these goals, the technical solution of the utility model is: a kind of monofilament reed structure for lens drive motor, comprise front side reed and rear side reed, it is characterized in that: described front side reed comprises in square gabarit and circle wide, four angles place of square gabarit is connected with wide in circle respectively by a U-shaped spring silk, described rear side reed comprises interior exterior feature, the inwall of described interior exterior feature is circular, outer wall is Octagon, described interior exterior feature is put together by symmetrically arranged interior exterior feature and lower interior exterior feature, the outside of described interior exterior feature and lower interior exterior feature is respectively arranged with two pieces of gabarits, every block gabarit all by a spring silk be adjacent that block gabarit corresponding in wide outer wall be connected.
The utility model discloses a kind of monofilament reed structure for lens drive motor, on front side of it, reed and rear side reed all adopt single spring silk structure, effectively promote stability during motor operation, further improve optical axis performance.Total Product is reasonable in design, is skillfully constructed, and has good practicability and stability.
