Abstract
The utility model discloses a connection structure of a front gasket and a lens carrier of a voice coil motor. The connection structure includes a front gasket and a lens supporting body; the inner peripheral surface of the front gasket sleeves the outer wall of the lens supporting body; a positioning groove is respectively formed at four corners of the inner peripheral surface of the front gasket; the outer wall of the lens supporting body is provided with four bosses; the bosses are matched with the positioning grooves; and gaps are left between the outer walls of the bosses and the positioning grooves. Compared with the prior art, and according to the connection structure of the utility model, the front gasket and the lens supporting body are matched with each other, so that the rotation of the lens supporting body can be prevented, and springs can be protected; and certain gaps are left between the lens supporting body and the front gasket, and the lens supporting body can move upwards normally, and at the same time, a position limiting effect can be realized, so that excessive deformation of the springs can be prevented.
Description
Technical field
The utility model relates to voice coil motor technical field, particularly the syndeton of a kind of voice coil motor front pad and lens carrier.
Background technology
The similar lens driver that existing domestic and international minisize pick-up head adopts adopts disclosed scheme in the disclosed lens driver of China Patent Publication No. CN1683946A more, stationary part is all made up of iron-clad and four equiform magnetites, and described magnetite is assembled in respectively four corners of iron-clad; Coil and lens supports body are fixed together, be placed in stator interior, this lens supports body together with coil in the iron-clad of stator and magnetite inside along center position forwards, backwards mobile described lens driver also comprise that front is to spring and rear to spring, their peripheries are fixedly connected with iron-clad and fixed lens supporter, front also has a framework that front is fixed on iron-clad to spring, the electromagnetic force producing after coil electricity overcomes the precompressed elastic force that front produces to spring to spring and rear, orders about lens supports body and moves along optical axis direction.But it is external to adopt iron-clad to be nested with in lens supports, lens supports body easily produces rotation in the time of motion, can produce torsion to front and back spring, the damage of spring before and after causing.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, can prevent the voice coil motor front pad of lens supports body rotation and the syndeton of lens carrier.
For achieving the above object, the utility model is implemented according to following technical scheme:
The syndeton of a kind of voice coil motor front pad and lens carrier, comprise front pad, lens supports body, the inner ring surface of front pad is nested with at the external wall of lens supports, four angles of the inner ring surface of described front pad arrange respectively locating slot, the outer wall of described lens supports body arranges four boss, boss matches with locating slot, between described outer wall of boss and locating slot, leaves gap.
As preferably, described locating slot and boss are set to square or arc.
As preferably, described locating slot and boss are set to respectively 2 ~ 8.
Compared with prior art; the utility model front pad and lens supports body are combined together; can prevent the rotation of lens supports body; play the effect of protection spring; between lens supports body and front pad, ensure certain gap; lens supports physical efficiency normally moves up, and the effect of limited location, prevents the excessive deformation of spring simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model front pad;
Fig. 2 is the structural representation of the utility model lens supports body;
Fig. 3 is the assembling schematic diagram of the utility model front pad and lens supports body.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, is used for explaining the utility model in illustrative examples and the explanation of this utility model, but not as to restriction of the present utility model.
Voice coil motor front pad as shown in Figure 1, Figure 2, Figure 3 shows and the syndeton of lens carrier, comprise front pad 1, lens supports body 3, the inner ring surface of front pad 1 is nested with at lens supports body 3 outer walls, four angles of the inner ring surface of described front pad 1 arrange respectively locating slot 2, the outer wall of described lens supports body 3 arranges four boss 4, boss 4 matches with locating slot 2, between described boss 4 outer walls and locating slot 2, leaves gap.
As preferably, described locating slot 2 and boss 4 are set to square.
As preferably, described locating slot 2 and boss 4 are set to respectively 4.
The utility model front pad 1 and lens supports body 3 are combined together; boss 4 matches with locating slot 2; prevent that lens supports body 3 from rotating; play the effect of protection spring; between lens supports body 3 and front pad 1, ensure certain gap; lens supports body 3 can normally move up, and the effect of limited location, prevents the excessive deformation of spring simultaneously.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model, within all falling into protection domain of the present utility model.
