Abstract
The invention discloses a vibration motor. The vibration motor comprises a stator, an armature, an installation part and a flexible assembly, wherein the flexible assembly is connected between the armature and the installation part, the vibration motor also comprises a workpiece assembly, the workpiece assembly is installed on the armature and extends out of the armature, the flexible assembly comprises two steel sheets propping against each other, each steel sheet comprises an arc part and planar parts, the planar parts are arranged at the two ends of the arc part, and the two steel sheets are horizontally arranged between the installation part and the armature. During the arch movement of the flexible assembly, the two ends arranged on the arc part serve as fulcrum points for the deformation of the steel sheets, deformation quantity can be accumulated in the steel sheets by taking the two endpoints as the fulcrum points, and thus, the problem that the steel sheets are easily damaged due to force applied to a single fulcrum point is avoided. With the structural design of the arc part, a deformed force applied to one endpoint is rapidly transferred to the other endpoint through the arc part when the force is firstly applied to the endpoint of the arc part, meanwhile, elastic potential energy required for resilience is accumulated through slight deformation of the arc part, and namely, the two endpoints of the arc part and the arc part per se are used for accumulating the deformation quantity of the steel sheets during swinging.

Technical field
The present invention relates to machine field, more specifically, relate to a kind of vibrating motor.
Background technology
Appliance for personal care utilizes internal motor to produce specific workpiece movement/action usually, then produces the function result of hope.The example of this apparatus comprises electronic skin brush, electric toothbrush and electric shaver etc.
The motor arrangement of much this equipment produces vibration (front and back) action, and does not produce pure rotational motion.This layout not only needs typical motor bearing structure to support this motion, also needs special structural detail that the motion of motor drive shaft and workpiece is limited to selected angle/motion.This bearing or other elements usually can increase significant cost to the manufacture of apparatus and manufacture difficulty, also can increase the consideration of stability/durability to the use of apparatus.
Be " CN200780044634.5 " to this number of patent application, name is called in " vibrating motor of appliance for personal care " and discloses a kind of vibrating motor structure, comprise the E shape iron core stator module with AC power, and be installed into the armature portion in response to stator along the arc porpoise of selected angle.Installing component is fixed on the housing parts of appliance for personal care, flexible member is connected between armature and installing component, described flexible member is made up of spring steel material, is two steel discs intersected with each other, wherein crosspoint define armature rotate around fulcrum.The workpiece assembly comprising hold-down arm is configured to make the skin be arranged on the free end of hold-down arm be brushed with the axle rotated around fulcrum.
Above-mentioned patent has following shortcoming: 1) due to two steel discs that flexible member is intersected with each other, and two steel discs do not connect, it is installed and inconvenience very when installing component and armature portion, the mode of injection mo(u)lding can only be adopted to be injection-moulded in installing component and armature portion, and this result also in above-mentioned flexible member and will be difficult to change after damage; 2) form of two steel discs intersected with each other, namely steel disc needs oblique being arranged between armature and installing component, and one end that steel disc is connected with armature portion must have the part of magnet near armature portion, and length when steel disc is arranged increases; 3) when steel disc resilience, steel disc and installing component junction are as the fulcrum of resilience, and all the other positions of steel disc all deformation do not occur, and make steel disc and the deformation of installing component junction when resilience comparatively large, in long-term deformation cumulative process, easily produce fault.
Summary of the invention
For the deficiencies in the prior art, the invention provides vibrating motor.
The present invention is achieved through the following technical solutions: vibrating motor, comprise stator, the armature of bow-shaped route motion is made in response to the action of described stator, be fixed to the installing component on the housing parts of described appliance for personal care and flexible component, described flexible component is connected between described armature and described installing component, also comprise workpiece assembly, it to be installed on described armature and to extend from described armature, make the vibration passing on described armature to described workpiece assembly, described flexible component comprises two steel discs mutually leaned, the planar section that described steel disc comprises circular arc portion and arranges at described circular arc portion two ends, two steel discs are horizontally placed between described installing component and described armature.
In technique scheme, be upwards bent to form inserted sheet in one end of described planar section, described installing component and described armature are provided with the slot coordinated with described inserted sheet.
In technique scheme, described slot cross section is T-shaped.
In technique scheme, described stator comprises the E shaped iron core with center leg and two side legs, and described center leg is provided with coil.
In technique scheme, described armature comprises the afterbody of the expansion that lug boss is connected with in lug boss one end, is arranged at intervals with two magnets at described afterbody, and described center leg end is between two magnets.
The present invention has following beneficial effect: flexible component of the present invention adopts two steel discs mutually leaned, steel disc has two planar portions that arc sections is connected with in arc sections, and two steel discs are horizontally set between flexible component and installing component, flexible component do namely arc (also arc) move time, the two ends being positioned at described arc sections all become fulcrum during steel disc deformation, now steel disc can accumulate deformation quantity using this two-end-point as fulcrum, avoid the stressed problem easily making steel disc damage of single fulcrum, in addition the structural design of arc sections, make when one end points is first stressed, by arc sections, the deformation power received of one end points is passed to the other end rapidly, the arc sections elastic potential energy of deformation accumulation needed for resilience slightly simultaneously, be equivalent to the two-end-point of arc sections and the deformation quantity of this three partials steel disc of arc sections swing itself.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail: see Fig. 1 to Fig. 3, vibrating motor, comprise stator 1, the armature 2 of bow-shaped route motion is made in response to the action of described stator 1, be fixed to the installing component 3 on the housing parts of described appliance for personal care and flexible component 4, described flexible component 4 is connected between described armature 2 and described installing component 3, also comprise workpiece assembly 5, workpiece assembly 5 be mainly used in personal nursing for brushhead portion be connected, such as with clean brush brush or be connected with electric toothbrush head, it to be installed on described armature 2 and to extend from described armature 2, make the vibration passing on described armature 2 to described workpiece assembly 5.
Described flexible component 4 comprises two steel discs 40 mutually leaned, the planar section 40a that described steel disc 40 comprises circular arc portion 40b and arranges at described circular arc portion 40b two ends, and two steel discs 40 are horizontally placed between described installing component 3 and described armature 2.Upwards be bent to form inserted sheet 40c in one end of described planar section 40a, described installing component 3 and described armature 2 are provided with the slot 6 coordinated with described inserted sheet 40c.Described slot 6 cross section is T-shaped.When steel disc 40 is arranged, directly by by inserted sheet 40c partial insertion slot 6, convenience all very can be mounted and dismounted.
