Abstract
The utility model discloses a kind of eccentric rotors: including shaft, the shaft is equipped with the eccentric block of integral structure.It can be realized and couple without other components or structure between the eccentric block of the utility model and shaft, structure is simple, and reliable performance is less prone to failure, provides the global reliability of vibrating motor.
Description
Technical field
The utility model relates to technical field of motors, and in particular to arrive a kind of eccentric rotor.
Background technique
Vibrating motor used in existing health care and nursing small electric apparatus is typically all common motor with eccentricity balance-weight block
Structure, vibration is realized by the rotation of eccentricity balance-weight block.In general, eccentricity balance-weight block is mounted on the output shaft of motor, especially
Electric toothbrush as shown in Patent Document 1, be provided with the eccentric rod of lengthening, intermediate connector is more, therefore poor reliability.This
Outside, the structure of this more than one piece connection certainly exists installation gap, can generate additional noise.

Utility model content
In order to simplify the structure of vibrating motor, the utility model provides a kind of eccentric rotor.
The technical solution adopted in the utility model is as follows:
A kind of eccentric rotor, including shaft, the shaft are equipped with the eccentric block of integral structure.
The beneficial effects of the utility model are: being not necessarily to other components or structure between the eccentric block and shaft of the utility model
Connection can be realized, structure is simple, and reliable performance is less prone to failure, provides the global reliability of vibrating motor.
It is preferred: be fixed with bobbin in the shaft, and be wound with winding, the bobbin by silicon steel sheet group at, or
Person adds iron core to form by plastic skeleton.
Preferred: the shaft is mounted on stator module by two bearings, and a bearing is located at the coil
The lateral ends of frame, another described bearing are located at the lateral ends of the eccentric block or are located at the bobbin and bias
Between block.
Preferred: the eccentric block includes the semicolumn of newel and outside, the newel and semicolumn integral structure.
Preferred: the eccentric block is integrated the plastic part of injection molding with shaft.

Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
In embodiment, as shown in Fig. 1 ~ 4: a kind of eccentric rotor 2, including shaft 202, the shaft 201 are equipped with one
The eccentric block 201 of structure.It can be realized and couple without other components or structure between the eccentric block 201 of embodiment and shaft 202,
Structure is simple, and reliable performance is less prone to failure, provides the global reliability of vibrating motor.
In embodiment, as shown in Figure 1 and 2: it is fixed with bobbin 203 in the shaft 202, and is wound with winding 204, institute
Bobbin 203 is stated by silicon steel sheet group at or adding iron core to form by plastic skeleton.Bobbin 203 is pieced together if it is by silicon steel sheet
It forms, the later period is needed to be fixed on shaft 202；Bobbin 203 adds iron core if it is plastic skeleton, then plastic skeleton can lead to
Injection molding is crossed, realizes the integral structure with shaft 202.
In embodiment, as shown in Figure 4, Figure 5: the shaft 202 is mounted on stator module 1 by two bearings 3, and one
The bearing 3 is located at the lateral ends of the bobbin 203, another described bearing 3 is located at the outside one of the eccentric block 201
It holds or between the bobbin 203 and eccentric block 201.In Fig. 4, eccentric block 201 is located between two bearings 3, this
Structure can obtain biggish Oscillation Amplitude.In Fig. 5, eccentric block 201 is located at the outside of two bearings 3, this structure lines coil
203 is good with the structural stability of winding 204, and motor performance is more stable.
In embodiment, as shown in Figure 3: the eccentric block 201 includes newel 205 and external semicolumn 206, it is described in
Stem 205 and 206 integral structure of semicolumn.The newel 205 of the present embodiment is used for, semicolumn 206 conduct fixed with shaft 202
Counterweight part, weight are completely in extent of the error, therefore under same eccentric performance, size can accomplish minimum, so as to subtract
The overall dimensions of few motor.
In embodiment, the eccentric block 201 and shaft 202 of the present embodiment can be the plastic part of integrated injection molding, one is forged
Or the metalwork of casting, it is also possible to moulding or assembly welding part that shaft 202 makees mold insert.In short, eccentric block 201
Integral structure can be realized by way of various reasonable between shaft 202, connection can be realized without other components or structure
It connects, structure is simple, reliable performance.
Obviously, the above embodiments of the present invention is merely to illustrate that examples for clearly illustrating the present invention, and is not
Limitations of the embodiments of the present invention.For those of ordinary skill in the art, on above explained basis
On can also make other various forms of variations or variation.There is no need and unable to give poor example to all embodiments.
And these connotation changes and variations that derived from for belonging to the utility model still fall within the utility model
Protection scope.
