In the prior art, oscillator moves reciprocatingly when motor works, and oscillator is the part that weight is maximum in motor, if motion
The too big compression spring of amplitude is to its deformation limit, or even can exceed the compression travel of its permission, because spring needs to have necessarily
Coefficient of elasticity moved back and forth for oscillator restoring force be provided, it is impossible to simply change that its is elastic, otherwise can influence the vibration of oscillator, because
This prior art easily causes spring breaking down, so as to shorten the service life of motor, can not meet use demand.
Utility model content
The utility model is that compression spring causes camber of spring to damage in order to overcome prior art oscillator vibration amplitude excessive
It is bad, shorten motor service life the problem of, there is provided a kind of linear vibration electric motor need not change the coefficient of elasticity of spring, can effectively control
The reciprocating amplitude of damping, so as to protect spring, extend motor service life.
To achieve these goals, the utility model uses following technical scheme：
A kind of linear vibration electric motor, including the shell with receiving space, the oscillator that is arranged in the shell and use
In the elastomeric element of support oscillator, the madial wall of the shell, which is located at oscillator both sides, is provided with spacing groove, the spacing groove
Integrally it is provided with what is extended to housing inner bending with a side parallel with the oscillator vibration direction, and along the side
Banking stop；The elastomeric element is U-shaped spring leaf, and side is welded on oscillator, and opposite side is welded on the housing interior side-wall.Adopt
With this programme, when motor works, oscillator moves reciprocatingly in a certain direction, continuous compression spring.When amplitude is excessive, close to bullet
Before spring deformation limit, oscillator can first touch banking stop, stop travelling forward in the presence of banking stop, and to it is opposite reversely
Motion, prevents spring from can not recover deformation by excessive compression, has reached the purpose of protection spring, has extended motor and use the longevity
Life.The banking stop avoids the extra spacing part of increase with the structure that the shell integral type is connected, and convenient processing, saves
Cost.In addition, described spring is U-shaped spring leaf.The restoring force in main movement direction can not only be provided for oscillator, also provide one
The individual restoring force perpendicular to main movement direction so that oscillator vibration direction is not single, has reached more preferably vibrating effect.
Preferably, the oscillator includes some masses, it is detachably connected between adjacent mass.Using we
Case, can be by the weight for the quantity flexible modulation oscillator for adjusting mass, that is, oscillator weight can be increased by increasing the quantity of mass,
Oscillator weight can be reduced by reducing the quantity of mass, to reach the purpose of different vibrating effects.
Preferably, the shell includes housing and upper lid, the housing and the upper lid clamping.Using the skill of the present invention
Art scheme, by the housing and the upper lid is connected by screw rather than welding manner commonly used in the prior art, can be in electricity
Machine resting state covers on opening, convenient that casing internal part is cleared up and repaired.
Preferably, connected between the mass by sliding shoe.The connected mode of sliding shoe can realize mass
Between flexible dismounting, can also reach firm close-connected purpose, ensure the security under the vibration of oscillator high-frequency.
Therefore, the utility model has the advantages that：（1）Prevent spring from can not recover deformation by excessive compression,
Reach the purpose of protection spring, extend motor service life；（2）The weight of flexible modulation oscillator is to reach different vibrations
The purpose of effect；（3）It is convenient that casing internal part is cleared up and repaired.
