Fig. 2 is a kind of assembling schematic diagram of lower elastic sheet damping structure of closed loop voice coil motor of the utility model；
The carrier and the elevational schematic view after the assembling of lower elastic slice that Fig. 3 is the utility model.
Specific embodiment
As shown in Figures 1 to 3, a kind of lower elastic sheet damping structure of closed loop voice coil motor of the utility model, comprising: pedestal
2, lower elastic slice 3 and carrier 1；Lower elastic slice 3 includes inside casing 4, outline border 5 and four plastic structures 6 for connecting inside casing and outline border.The point
Plastic structure 6 includes the horizontal bar 63 of two damping glue applying structures of two damping glue applying structures, 61, two elater 62 and connection,
Damping glue applying structure 61 is connected by elater 62 with corresponding inside casing 4 or outline border 5；The lower elastic slice 3 and the assembling of carrier 1 are fixed
The horizontal bar 63 at the mouth of a river of plastic structure 6 is cut off afterwards together, after applying damping glue on damping glue applying structure 61, the mouth of a river
The damping glue applying structure 61 of breakpoint two sides is by damping glue sticking, then lower elastic slice 3 is assembled on pedestal.
The carrier 1 and lower elastic slice 3 fit together, and are fixed, are put at this time cementing by coating hot-setting adhesive after riveting
Structure 6 links together the inside casing 4 of lower elastic slice 3 and outline border 5, prevents elastic slice when riveting from deforming；Laser is reused to lower elastic slice 3
The mouth of a river of point plastic structure 6 cut, 6 remainder of point plastic structure after cutting will form two semicircular damping glues and apply
Cloth structure 61 is coated with for damping glue.To guarantee that the semicircular damping glue applying structure 61 of two sides is indeformable when cutting.Damping
After glue is coated, reversion is assembled on pedestal 2.
As shown in Figures 2 and 3, evacuation design is made at the point plastic structure 6 of corresponding lower elastic slice 3 on the carrier 1, reserves safety
Distance；The inside casing 4 of lower elastic slice 3 is equipped with first positioning hole 41, and carrier 1 is equipped with first with the cooperation positioning of first positioning hole 41
Positioning column 11.Design has been done at corresponding points plastic structure 6 on the pedestal 2, has reserved safe distance；It is set on the outline border 5 of lower elastic slice 3
There is second location hole 51, the quadrangle of pedestal 2 is equipped with the second positioning column 21 with the cooperation positioning of second location hole 51.
The utility model by the way that lower elastic sheet damping structure is arranged, can make closed loop voice coil motor rapid focus when
It waits, the damping glue meeting when carrier movement arrives designated position, when carrier stress moves, in semicircular glue application structure 61
It first stretches and comes, play first step buffering effect.Damping glue deformation to a certain extent when, be connected respectively to inside casing 4 and outline border 5
On elater 62 slight deformation can also occur, play the effect of secondary buffer；Simultaneously because the deformation of the elater 62 avoids resistance
Buddhist nun's glue stretches too long, avoids damping glue and breaks or fall off, enhances product performance and quality.
The above is only the preferred embodiment of the present invention, the thought being not intended to limit the utility model, it is all
Within the spirit and principles of the utility model, it is practical new to should be included in this for any modification, equivalent replacement, improvement and so on
Within the protection scope of type.
