Abstract
A kind of miniature cylinder motor, the diameter of casing is less than or equal to 3.2mm, while reduced volume, ensures after receiving electric signal, have the reaction speed be exceedingly fast, and the oscillation intensity of User Satisfaction can be reached, described motor also can just use metal clips connecting signal source with lead-in wire connecting signal source.
Description
Technical field
The utility model relates to a kind of miniature cylinder technical field of motors, be specially be applied in mobile phone or need drive electronic product and toy on.
Background technology
Along with the development of science and technology, the progress of electronics techniques, mobile phone and each electronic product small, the especially lightening development of touch-screen mobile phone, more and more higher to the accessory precision requirement of electronic product inside.The present invention relates to vibrating motor technical field, the size of product directly affects the thickness of finished product.
Drag cup cylinder motor mainly contains 2 functions: vibrating function and driving function.
1) vibrating function: as cell phone incoming call talk about time, except the tinkle of bells, also have vibrating function, be convenient to reminding user accurately, and for example automotive lock, door lock and for antitheft and adopt the vibrating function except the tinkle of bells, warning lamp abroad, and adopt this kind of motor.
2) function is driven: at miniature toy helicopter, blade toy, Automobile drive, action figure walks about, and the parts of every motion need the place of power source, all must adopt motor.
Because motor itself is rotary body, will have relative gap during assembling, very high to the precision of equipment, frock, fixture and tool demands during assembling, all there is size problem bigger than normal in the motor of prior art.
Summary of the invention
In order to solve and that cause electronic product thickness excessive technological deficiency excessive due to motor, under the performance prerequisite of satisfied vibration and driving, instant invention overcomes the deficiencies in the prior art, a kind of miniature cylinder motor is provided.After receiving electric signal, there is the reaction speed be exceedingly fast, and the oscillation intensity of User Satisfaction can be reached, reduce the volume size of cylinder motor simultaneously as much as possible.
Subtract undersized object to reach, the technical scheme of employing is:
A kind of hollow cup cylindrical vibrating motor comprises field frame assembly, rotor assembly, armature assembly and oscillator, and described rotor assembly is arranged on field frame assembly inside, connects oscillator by the rotor rack in the middle of rotor assembly; Described armature assembly is arranged on field frame assembly side.Can outside source be accepted at described armature assembly, provide described rotor assembly to produce and rotate, for the effect of vibration of cylinder motor provides power source.
Described casing diameter is less than or equal to 3.2mm, and length is less than or equal to 8mm.
Described field frame assembly two ends are separately installed with oscillator and armature assembly, and described armature assembly comprises brush, end cap, lead-in wire and gum cover, is connected with outside source.Rotor assembly is fixed on field frame assembly inside through the pad of field frame assembly, upper bearing (metal), casing, bearing holder (housing, cover), magnet and lower bearing by described rotor rack.Described bearing holder (housing, cover) is in the outermost of motor.
Advantage of the present invention is the diameter, the volume that reduce motor, makes motor be applicable to more accurate instrument or the synchronous volume reducing to use instrument, realizes the innovation progress of equipment.

Embodiment
See Fig. 1 to Fig. 3, a kind of miniature cylinder motor of the present invention embodiment, comprise field frame assembly, rotor assembly, armature assembly and oscillator 1, oscillator 1 and armature assembly are arranged on the two ends of field frame assembly, rely on rotor rack 9 fixed position.
Described field frame assembly comprises upper bearing (metal) 4, casing 5, bearing holder (housing, cover) 6, magnet 7 and lower bearing, and magnet 7 is enclosed within bearing holder (housing, cover) 6, and upper bearing (metal) 4 is arranged in the little opening of casing 5, with oscillator 1 spacing washer S2 and pad T3; Lower bearing 8 is arranged on casing 5 big uncork one end.
Described rotor assembly.Rotor rack 8 stub end contacts with armature assembly, and coil 10 is enclosed within rotor rack 8 and between magnet 7 certain space, and rotor rack 9 runs through the location mid-shaft that each for field frame assembly assembly is fixed on casing 5 by field frame assembly.
Described armature assembly, is arranged on brush 11 inside end cap 12, and lead-in wire 13 is connected with brush 11 through the aperture on end cap, and end cap 12 is fixed on casing 5 big uncork place, is sealed by casing 5, the assembly in fixing casing 5.Outside casing 5, gum cover 14 on cover, reduces the vibration of casing, reduces wear, and can prevent entering of steam, effectively extends the useful life of motor.
Claims (7)
