Description

A kind of spring slice fixing structure

Technical field

The utility model relates to the installation of drive motor elastic slice, in particular to a kind of spring slice fixing structure.

Background technique

Webcam driver motor is gradually thinned as 3.8,3.5,3.2 highly from original 4.2mm height, is thinned again in recent years For 3mm ultrathin motor below, the main path how to be preferably thinned using inner space at motor.

So the improvement of spring slice fixing structure then becomes more important a part, as shown in Figure 1, traditional drive motor Fixed elastic slice is mostly four modular constructions, including upper cover 100, elastic slice 200, shell 300 and magnetite 400, in assembled and processing work It is all complex in sequence, and thickness is larger, and there are also a kind of structures to be similarly four modular constructions, but it removes the upper of traditional structure Lid, using elastic slice built in shell, but needs to fix using gasket, and this frame mode technique is assembled complicated.

Summary of the invention

The utility model is different from four traditional modular constructions to solve the above problems, provide a kind of spring slice fixing structure, Under the premise of not changing properties of product, reduce product height, while also reducing product assembly step, and reduce product at This.

In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of spring slice fixing structure, including shell, Elastic slice and magnetite, housing central section are the motor mover installation activity chamber of perforation, and four ends angle is equipped with platform, and case inside is four Baffle is additionally provided at a end angle, platform is used for fixation spring tab and magnetite, and baffle is used for magnetic conduction, increases the magnetic field of local magnetic field Power, the difference in height between any two platform are less than or equal to 0.02mm.

Further, shell is metal shell, and is ferrous casings；

Further, there is gluing connection between shell and elastic slice, magnetite.

In conclusion the utility model has following advantages:

Four original part fixing structures are improved to three modular constructions by the utility model, and conventional elastic piece is fixed by upper cover, I.e. upper cover and shell are separate structure, and such mold opening cost is big, and this structure is integrated inside housings by elastic slice, and is metal-back Body eliminates upper cover, ensure that the integrality of motor, avoids the exception of upper cover disengaging.

Also, four are held the podium level difference at angle to control within 0.02mm by this structure, can be not necessarily to the use of gasket, To relatively simple in manufacturing procedure, more traditional processing is more simplified, and the production cycle shortens.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and embodiments:

Embodiment 1:

A kind of spring slice fixing structure, as shown in Figures 2 and 3, including shell 1, elastic slice 2 and magnetite 3, specifically, 1 middle part of shell For the motor mover installation activity chamber 11 of perforation, for installing motor mover, and four of shell 1 ends angle is equipped with platform 12, 1 inside of shell is additionally provided with baffle 13 at the angle of four ends, wherein the difference in height between any two platform 12 is less than or equal to 0.02mm。

With continued reference to attached drawing 1, and in conjunction with attached drawing 2, platform 12 is for fixing institute's elastic slice 2 and magnetite 3, and magnetite is in motor Magnetism is generated, baffle 13 is used for magnetic conduction, increases the magnetic field force of local magnetic field.

Preferably, shell 1 is metal shell, and is ferrous casings, while having gluing between shell 1 and elastic slice 2, magnetic 3 Connection.

It is further described, conventional elastic piece structure is as shown in Figure 1, there are four components, from procedure of processing It says, needs to carry out upper cover and place dispensing, shoot piece, fill shell, fill magnetite, entering to dry case, multiple processes such as general assembly, even there is pad The spring slice fixing structure of piece, there is also gaskets to install process for dispensing glue, and this structure is in processing, it is only necessary to shell placement is carried out, Dispensing shoots piece, fills magnetite, dispensing, and general assembly is significantly reduced processing upper step.

Above embodiment is only to illustrate the technical ideas and features of the present invention, and its object is to allow be familiar with this skill The people of art can understand the content of the utility model and implement accordingly, not limit the protection scope of the present invention. It is all according to the spirit of the present invention substantially equivalent transformation that is done or modification, should all cover the protection scope of the utility model it It is interior.
