Art scheme is as follows：
A kind of vibrating motor with eccentric structure, including shell, end cap, rotor and being arranged on housing interior side-wall are determined
Son, power connection and brush are provided with end cap, rotor includes rotating shaft, iron core and commutator, and iron core is made up of multiple laminations,
Each lamination is connected in the middle part of rotating shaft by contiguous block, and commutator is arranged on the rear end of rotating shaft, it is characterised in that：At least
Coil windings are provided with one contiguous block, at least one contiguous block is arranged to sky winding, each coil windings continuous phase
Neighbour, each empty winding continuous adjacent.
Above-mentioned empty winding refers to be not provided with coil windings on contiguous block.
Due to rotor being arranged to include unsymmetric structure as coil windings and empty winding so that rotor is formed in itself
Eccentric structure, rotor produces vibrations while rotating, simple and compact for structure, and is not take up extra installing space, it is not necessary to is
Vibrating motor is designed for the activity space of eccentric wheel, and any influence, convenient vibration will not be produced on the mounting structure of vibrating motor
The actual installation of motor.
As preferred scheme of the present utility model, in addition to eccentric wheel, eccentric wheel is arranged in the rotating shaft and is in institute
State housings.Eccentric wheel is set up, increases the intensity of vibration, and eccentric wheel is not take up extra to be arranged on housings
Installing space, it is not necessary to the activity space of eccentric wheel is designed for for vibrating motor, the mounting structure of vibrating motor will not be produced and appointed
What influences, and facilitates the actual installation of vibrating motor.
As the further preferred scheme of the utility model, the eccentric wheel be in the iron core and the commutator it
Between.Eccentric wheel is arranged between iron core and commutator, makes whole rotor structure compacter, rotor can when being assembled with stator
More spaces are saved, are advantageous to the optimization of vibrating motor structure.
As the further preferred scheme of the utility model, the eccentric wheel is bonded by least 2 half-round metal thin slices
Form.Eccentric wheel is using at least 2 half-round metal thin slice bondings, it is ensured that matter necessary to produce vibration during rotor motion
Measure deviation, it is ensured that the normal operation of vibrating motor.
As the further preferred scheme of the utility model, the eccentric wheel is bonded by 3 ~ 5 sheet metals.Enter
One step limits the sheet metal of composition eccentric wheel as 3 ~ 5, optimizes the size of rotor, while reduce vibrating motor in the course of work
Active force of the middle rotating shaft by eccentric wheel.
The utility model compared with prior art, has the following advantages that：
There is the utility model the vibrating motor of eccentric structure to be arranged to rotor to include coil windings and empty winding so
Unsymmetric structure so that rotor forms eccentric structure in itself, and rotor produces vibrations while rotating, simple and compact for structure,
And extra installing space is not take up, facilitate the actual installation of vibrating motor；In addition, bias is set up between iron core and commutator
Wheel, both increases oscillation intensity, is also not necessarily the activity space that vibrating motor is designed for eccentric wheel, will not be to the installation of vibrating motor
Structure produces any influence.
