Description

A kind of clad type vibrating motor

Technical field

The present invention relates to micromachine field, particularly relate to a kind of clad type vibrating motor.

Background technology

As having the vibrating motor of motor housing, as disclosed in the file of China Authorization Notice No. CN204103679U Content, motor housing at least covers a part of FPC and protects FPC, can not only prevent due to the vibration of motor or from outward The impact in portion and the FPC disconnection problem that causes, and can easily vibrating motor main body be embedded in motor housing.

But, technical scheme disclosed in it there is also many weak points: the otch area on motor housing is excessive, eccentric Hammer place end face is Full-open end, and the stability thus making its vibrating motor is not enough；Motor end cap place end face is full envelope Closed end so that the machine-shaping difficulty of motor housing is big and cost is high, the production for motor brings certain difficulty.

In view of problem above, the present invention will disclose a kind of clad type vibrating motor, make vibrating motor body peripheral face be coated with face Long-pending maximization, improves vibrating motor job stability, meanwhile, uses the outer housing otch optimized and end face to arrange so that the disclosure Vibrating motor produces simple, low cost.

Summary of the invention

The present invention provides a kind of clad type vibrating motor, is mainly made up of vibrating motor main body and covered stent, vibrates horse Reaching one end that main body rotating shaft stretches out and be provided with eccentric hammer, the other end relative with eccentric hammer is provided with end cap, and end cap is provided with Flexible PCB, it is characterised in that:

The center, one end of covered stent has through hole, and the relative other end is open end, and vibrating motor rotating shaft is along axle To passing through hole from open end；Covered stent side face is provided with being parallel to axial extraction otch, be perpendicular to axially and with extraction The first otch that backward first plane of otch connection extends and be parallel to axially the most vertical with the first otch extend also to open end The second otch connected with the first otch, wherein, the axial width of the first otch is less than the axial width drawing otch；Flexible electrical Road plate is drawn outside covered stent by drawing otch.

Described covered stent is one-body molded by elastomeric material.

The diameter of described through hole less than the side face diameter of vibrating motor metal shell, more than protuberance on metal shell outside Footpath.

The beneficial effects of the present invention is: by covered stent, vibrating motor body peripheral face area is maximized covering, make Obtain motor operation more stable, meanwhile, make covered stent produce letter by the optimal design-aside of covered stent upper cut and end face Just, low cost, and motor packaging efficiency is high.

Accompanying drawing explanation

More easily understand for convenience of technical solution of the present invention, will illustrate in conjunction with accompanying drawing once.

Fig. 1 is a schematic diagram of vibrating motor main body.

Fig. 2 is clad type vibrating motor schematic diagram.

Fig. 3 is covered stent schematic diagram.

Reference: 1-moves motor body, 2-covered stent, 11-eccentric hammer, 12-end cap, 13-flexible PCB, 14- Metal shell, 141-metal shell protuberance, 142-metal shell side face, 21-draws otch, 22-the first otch, 23-second Otch, 24-through hole, 25 first planes.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is further described, more to understand technical scheme.

One end that in Fig. 1, vibrating motor main body 1 rotating shaft is stretched out is provided with eccentric hammer 11, the other end peace relative with eccentric hammer Equipped with resin-made end cap 12, end cap is installed by welding with flexible PCB 13.

In Fig. 1, Fig. 2 flexible PCB 13 fit in after being installed on end cap motor body 1 lower plane be parallel to axially to Eccentric hammer 11 direction extends to about 1/2 motor axial length, then proceedes to fit in motor body 1 lower plane to be perpendicular to axially Extend to motor periphery.

In Fig. 3, covered stent 2 is coated with motor body 1, and one end of covered stent 2 is provided with through hole 24, relative with through hole 24 The other end be open end, the rotating shaft that motor body 1 is stretched out vertically from open end through through hole 24, covered stent 2 circumference On be provided with and be parallel to axial extraction otch 21, flexible PCB 13 is drawn outside covered stent 2 by drawing otch 21, draws Otch 21 is more than flexible PCB 13 width dimensions in this place at axial width；It addition, outside for making motor body 1 with rubber Shell 2 is easy to assembly, be easily achieved, and rubbery outer cover 2 is additionally provided with and is perpendicular to axially extend to the first plane 25 and cut with extraction First otch 22 of mouth connection, and it is parallel to the second otch 23 axially extending to open end and connecting with the first otch, for Enabling covered stent to cover vibrating motor body peripheral face as much as possible, the axial width of described first otch 22 need to be less than described Draw the axial width of otch 21.

Simultaneously as covered stent 2 needs to be mutually located with vibrating motor main body, the diameter of described through hole 24 should be less than institute State the diameter of the metal shell side face 142 of the metal shell 14 of vibrating motor main body 2, and more than metal shell protuberance 141 External diameter.

It is further preferred that described covered stent 2 is one-body molded by elastomeric material.
