In the cavity；The upper and lower casing is provided with radiator window and penetrates the cavity.
The stator module includes silicon steel sheet, fixes coil rack on the silicon steel sheet and around being located at the coil bone
Coil on frame.
The position that the radiator window corresponds to the coil is configured.
Annular groove, the card of the fixed flexible adjustment part end of the fixed bearing are formed after the upper and lower casing docking
Groove and the axis hole passed through for the rotating shaft.
The interface of the upper and lower casing is respectively formed with mutually chimeric boss and heavy platform, and by wear be connected on it is described
Fastener on boss and heavy platform realizes being connected for upper and lower casing.
The boss has the interior tooth screwed with the fastener threads.
There is the cylinder for being arranged damping rubber end after the upper and lower casing docking, and the damaged surface is provided with spline.
The beneficial effects of the utility model are：Described in the side for making stator module be docked as upper and lower casing during installation is embedded in
In cavity, then by the docking of upper and lower casing rotor assembly sandwiched is fixed, avoid stator module from being caused by hull outside setting-in
The problem of easily coming off, and anticreep bandage need not be wrapped up, simple in construction, assembling is very simple and efficient, and can be directly by passing through
The radiator window of logical cavity is radiated, and performance is more reliable and stable.

Embodiment
Referring to figs. 1 to Fig. 5, a kind of dither motor, including motor body 1, motor body 1 are included in frame-type docking
Upper and lower two stator module 11 and wear the rotor assembly 12 being connected between two stator modules 11；Rotor assembly 12 by rotating shaft 121,
Core assembly 122 and flexible adjustment part 123 are formed, and both ends are worn and are connected to bearing 124.
Dither motor also includes upper shell 2 and lower house 3, and upper and lower casing docking forms the sky of installation motor body 1
Chamber；Wherein, the inner side of the upper and lower casing is provided with cavity 4, and the side for making the stator module 11 be docked by upper and lower casing is embedding
Enter in cavity 4；Upper and lower casing penetrates the cavity 4 provided with radiator window 41.
Stator module 11 is first inlaid in the inner side of upper and lower casing during installation, then by the docking of upper and lower casing by rotor
The sandwiched of component 12 is fixed, and will not influence assembling because magnetic acts on, assembling is simple and efficient, simple in construction；And stator pack is not present
The problem that comes off when part is embedded in by hull outside, can be directly by outer provided with being through to inside cavity without wrapping up anticreep bandage
The radiator window in portion is radiated, and performance is more reliable and stable.
Stator module 11 includes the coil rack 112 and winding of silicon steel sheet 111, fixing on silicon steel sheet 111 in coil bone
Coil on frame 112；The position of the corresponding coil of the radiator window 41 is configured, better heat-radiation effect.
Reference picture 4, the annular groove 5 of fixing bearing 124 is formed after upper and lower casing docking, fixes the end of flexible adjustment part 123
Neck 6 and the axis hole 7 passed through for rotating shaft 121.
The interface of upper and lower casing is respectively formed with mutually chimeric boss 8 and heavy platform 9 simultaneously, is easy to upper and lower casing to exist
Positioning during docking, assembling is more easy, and the fastener 10 for being connected on by wearing boss 8 and heavy platform 9 realizes upper and lower casing 2,3
Fixation, and this fixed structure connected by fastener 10 is more firm compared to conventional interface arrangment, avoids motor
Generation is loosened and produces abnormal sound, and the left and right amplitude of motor is more uniformly distributed, and operation stability is more preferable, improves motor entirety
Performance.
Further, the boss 8 on lower house 3 has the interior tooth with the threaded engagement of fastener 10, and fastener 10 is through upper casing
Heavy platform on body 2 penetrates, with the interior tooth screw threads for fastening on boss 8.And thread is arranged on boss 8, make boss 8 can not only
Positioning is realized, while the threaded engagement depth with fastener 10 can be ensured, makes the threaded connection of fastener 10 and lower house 3 more
For fastening, without specially thickening housing wall thickness, manufacturing cost is reduced.
There is the cylinder for being arranged damping rubber reference picture 1, the end after upper and lower casing docking, are assembled to by damping rubber accommodating
In the housing such as electric toothbrush housing of vibration motor, to reduce influence of the motor vibrations to housing, and set in the damaged surface
There is spline 13, deformation space is inside contracted with certain when being inserted in damping rubber, and it is small with the friction of cylinder, so as to assemble more
It is light.
Dither motor of the present utility model, simple and reasonable, assembling is easy, and operation is more stable.
