Description
Technical field
The utility model relates to a kind of closed loop voice coil motor damping structure, buffering of quickly focusing suitable for camera.
Background technique
Closed loop voice coil motor (Close Loop VCM), being capable of certain journey as an emerging technology in cell-phone camera
The focusing accuracy and speed of mobile lens, while more power saving are improved on degree, improve the cruising ability of mobile phone, and bring
Better take pictures experience and image quality.And closed loop voice coil motor has that focusing speed is fast compared with traditional voice coil motor,
The advantages such as power consumption is low, these advantages all benefit from the rapid focus function of built-in sensors element realization.
Promotion of the closed loop voice coil motor compared with traditional voice coil motor compared to focusing speed is also along with the generation of a problem:
When that is exactly that closed loop voice coil motor interior carrier carries camera motion to designated position, since ontology is a spring knot
Structure, can there is carriers that in designated position, there is a situation where damping vibrations, will lead to the extension of focusing time in this way, to extend
Photo opporunity also reduces quality of taking pictures.
Summary of the invention
The purpose of this utility model is to provide for a kind of structurally reasonable, service-strong closed loop voice coil motor damping knot
The problem of structure fundamentally solves closed loop voice coil motor in rapid focus, carrier damping vibration, extends focusing time, shows
It writes and promotes focusing speed, guarantee quality of taking pictures.
The technical solution of the utility model is:
A kind of closed loop voice coil motor damping structure, including closed loop voice coil motor carrier and closed loop voice coil motor bottom
Seat, be characterized in that: the outer peripheral surface of the closed loop voice coil motor carrier is uniformly provided with multiple undertaking columns I, the closed loop sound
For circle motor with multiple undertaking columns II are uniformly provided on pedestal, the undertaking column I is equal with II quantity of column is accepted and corresponds, institute
It states to accept and is coated with damping glue between column I and the corresponding opposite face for accepting column II.
Above-mentioned closed loop voice coil motor damping structure, the cross section for accepting column I is T-shaped, by consolidating with carrier periphery
It is set to integrated radial carrier block, set on radial carrier block end and size is greater than the gluing expanding surfaces of tip dimensions and constitutes.It holds
On the one hand the setting for connecing column I is used for the welding of coiling and elastic slice, be on the other hand used for the coating of damping glue, is increasing coating damping
Prevent coiling from disengaging again while glue surface product.
Above-mentioned closed loop voice coil motor damping structure, the surface for accepting column II towards undertaking column I is equipped with pushes up with it
The storage glue groove that face communicates, the inner surface of the storage glue groove are rough surface.
Above-mentioned closed loop voice coil motor damping structure, the quantity accepted column I and accept column II is respectively four.
The beneficial effects of the utility model are:
1, by the way that the damping structure of the utility model is applied to closed loop voice coil motor, make closed loop voice coil motor fast
In fast focus process, when carrier movement is to designated position, the potential energy that carrier body carries is accepting column I and is accepting column II by point
Between damping glue carry out it is slow can, by carrier body because the kinetic energy that movement generates is converted in damping glue and can discharge, make
Designated position can be quickly parked in by obtaining carrier, achieve the purpose that rapid focus.
2, the undertaking column I of carrier is also used to coiling and the welding of elastic slice simultaneously, has in space utilization rate and damping
The raising of matter.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the carrier of the utility model；
Fig. 3 is the structural schematic diagram of the pedestal of the utility model.
In figure: 1. closed loop voice coil motor carriers, 2. closed loop voice coil motor pedestals, 3. accept columns I, 4. accept columns II,
5. storage glue groove, 6. gluing expanding surfaces.
Specific embodiment
With reference to the accompanying drawings of the specification and appended drawing reference elaborates to the utility model.
As shown in Figure 1-Figure 3, the closed loop voice coil motor damping structure, including closed loop voice coil motor carrier 1 and closed loop
Voice coil motor pedestal 2.The closed loop voice coil motor is uniformly provided with multiple undertaking columns I 3, the closed loop with the outer peripheral surface of carrier 1
For voice coil motor with being uniformly provided with multiple undertaking columns II 4 on pedestal 2, the undertaking column I 3 is equal with II 4 quantity of column is accepted and one by one
Corresponding, described accept is coated with damping glue (omitting in figure) between column I 3 and the corresponding opposite face for accepting column II 4.
The damping glue is non-condensable formula colloid, belongs to one kind of UV glue.It needs to use a standing wave under particular circumstances
Long UV light source is irradiated, and inside can after irradiation chemically reacted, damping glue itself becomes fruit from the colloid of flowing
The colloid for freezing shape, elastic deformation can occur after pullling, can be restored to original state after a certain time, the mechanical energy of carrier itself
Being converted to the interior of colloid can be to achieve the purpose that damping.Since colloid has very big ductility, in carrier movement, Bu Huiying
The proper motion of carrier is rung, but slow energy can be played the role of when carrier movement does damping vibration to designated position.
In the present embodiment, the quantity accepted column I 3 and accept column II 4 is respectively four.Wherein, the undertaking column I 3
Cross section it is T-shaped, by be fixed as one with carrier periphery radial carrier block, set on radial carrier block end and size is greater than
The gluing expanding surface 6 of tip dimensions is constituted.On the one hand the setting for accepting column I 3 is used for the welding of coiling and elastic slice, on the other hand use
In the coating of damping glue, prevent coiling from disengaging again while increasing and being coated with damping glue area.II 4 direction of undertaking column is accepted
The surface of column I is equipped with the storage glue groove 5 communicated with its top surface, and the inner surface of the storage glue groove 5 is the rough surface for being easy to kiss-coating.
When assembling, after carrier is fixed together with elastic slice, group is stood on pedestal, and carrier is made to form an entirety with pedestal.
Then by damping glue be uniformly coated on accept column I 3 and accept column II 4 between (damping glue click and enter accept column II 4 storage glue groove 5 in,
Glue, which can firmly be hung over, in this way accepts column I 3 and accepts between column II 4), four pairs of undertaking columns I 3 and undertaking column II 4 are coated with
Amount and uniform damping glue, the buffer of damping vibration is done as carrier after moving to designated position.
Technical principle of the utility model has been described above with reference to specific embodiments.These descriptions are intended merely to explain this reality
With novel principle, and it cannot be construed to the limitation to scope of protection of the utility model in any way.Based on the explanation herein,
Those skilled in the art, which does not need to pay for creative labor, can associate with other specific implementation modes of this utility model,
These modes are fallen within the protection scope of the utility model.
