Abstract

The utility model discloses a fixing support for a mobile phone motor, which is in an annular sleeve structure matched with a mobile phone motor in shape. Annular closing of the annular sleeve structure can be achieved by longitudinally adopting mutually fastened dovetailed structures, and an inwardly concaved positioning concave table serving as a further improvement is arranged on the fixing support. A parison of the fixing support is formed by stamping at one step by means of a progressive stamping die, two ends of the head-tail joint of the parison are jointed by means of the dovetail principle, a joint problem needs not to be solved by spot welding or gluing, and the fixing support is simple in process and fine in reliability. By means of the positioning concave table structure, weld strength of products on a PCB (printed circuit board) can be greatly enhanced, and the problem of insufficient weld strength can be resolved.

Description

The motor for cell phone fixed support

Technical field

The utility model relates to the micromachine technical field, particularly a kind of motor for cell phone fixed support.

Background technology

Fix by fixed support when being installed in the mobile phone vibrating motor in the mobile phone, existing mobile phone fixed support processing mode is to engage by spot welding or gluing two ends with support, to form tubular structure, such processing mode technology is comparatively loaded down with trivial details, had a strong impact on working (machining) efficiency, have also simultaneously that the individual component bonding strength is low, the problem of easy deformation, simultaneously, when assembling, might also slacken the constant intensity of circuit board simultaneously because welding causes the too high motor that burns out of temperature.

Therefore the motor for cell phone fixed support that need a kind ofly to be easy to assemble, bulk strength is high.

Summary of the invention

In view of this, the purpose of this utility model provides a kind of motor for cell phone fixed support that can strengthen bulk strength and be easy to assemble.

The utility model is achieved through the following technical solutions:

This motor for cell phone fixed support adopts and the adaptive annulus structure of motor for cell phone profile, and described annulus structure adopts the dovetail structure of mutual fastening to realize ring seal in the vertical.

Further, also be provided with the location concave station of indent on the described fixed support.

Further, described motor for cell phone fixed support comprise symmetrical and be arranged between lateral part surface I and the lateral part surface II before and after corresponding front retaining surface and rear retaining surfac, the area of described front retaining surface is less than rear retaining surfac.

Further, the dovetail structure of described mutual fastening is arranged on the junction between rear retaining surfac and lateral part surface I or the lateral part surface II.

Further, described location concave station is arranged on the center of front retaining surface.

Further, described fixed support is the elastic material sleeve.

The beneficial effects of the utility model are:

1. this support bracket fastened parison adopts the dovetail principle that two ends are engaged by the disposable punch forming of progressive stamping mould by the joint end to end at parison, need not to adopt spot welding or the gluing engagement problems that solves, and the simple and reliable property of technology is good;

2. the use of this product is welded on the PCB by SMT technology, so weld strength is extremely important, if adopt dull and stereotyped welding will cause intensity less, cause the product obscission, the utility model is by adopting location concave station structure, thereby strengthen the weld strength of product on pcb board greatly, solved the not enough problem of weld strength; Also have in the SMT welding process simultaneously, because temperature is very high, and the welding position temperature conduction is faster, by adopting location concave station structure, can reduce the high temperature injury of high temperature to motor body, thereby plays the effect of protection motor.

Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by following specification and claims.

Description of drawings

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:

Fig. 1 is the support bracket fastened perspective view of motor for cell phone;

Fig. 2 is the structural representation of dovetail structure.

Embodiment

Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only for the utility model is described, rather than in order to limit protection range of the present utility model.

Fig. 1 is the support bracket fastened perspective view of motor for cell phone; Fig. 2 is the support bracket fastened cross sectional representation of motor for cell phone; As shown in the figure: motor for cell phone fixed support of the present utility model adopts and the adaptive annulus structure of motor for cell phone profile, in the present embodiment, this motor for cell phone fixed support 1 comprises symmetrical lateral part surface I 11, lateral part surface II 12 and be arranged between lateral part surface I 11 and the lateral part surface II 12 before and after corresponding front retaining surface 13 and rear retaining surfac 14, the area of described front retaining surface 13 is less than rear retaining surfac 14, in the present embodiment, junction between rear retaining surfac 14 and lateral part surface II 12 is provided with the dovetail structure 15 of mutual fastening, dovetail structure 15 by mutual fastening realizes ring seal, forms the annulus structure in the vertical.In fact, this dovetail structure also can be arranged between rear retaining surfac 14 and the lateral part surface I 11.

As further improvement, on fixed support, also be provided with the location concave station 16 of indent.In the present embodiment, location concave station 16 is arranged on the center of front retaining surface.

Further improvement as the foregoing description, fixed support adopts elastomeric material to make, can adopt the rubber-like plastic production, also can adopt metal material to make, make it under the resilient force of self, produce inside pressure, thereby keep motor when work, not rock the micromachine of putting into wherein.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and the spirit and scope of the present utility model that do not depart from appended claims and limited.
