Vibration force in journey is adjusted.
The difficulty that vibration force during being intended for single use in view of existing vibrating motor is adjusted, sets again in conjunction with electric machine structure
A kind of positive and negative rotation structure of vibrating motor has been counted, client can be made to realize the positive and negative rotation of motor simultaneously by frequency converter in use
Two kinds of vibration forces are generated by changing the position of driven eccentric block during positive and negative rotation, solve vibrating motor in use process
In do not adjust the difficult problem of vibration force adjustment in the case where frequency.
Summary of the invention
The technical problem to be solved in the present invention and the technical assignment of proposition are to be improved and improved to prior art,
A kind of vibrating motor vibrational structure that different vibration forces are generated in positive and negative rotation is provided, to realize in the case where not changing frequency
For the purpose of making to rotate and reverse and generating two different vibration forces.For this purpose, the present invention takes following technical scheme.
A kind of vibrating motor vibrational structure generating different vibration forces in positive and negative rotation, including vibrating motor ontology, be set to
The intrinsic shaft of vibrating motor, the active eccentric block in shaft and the driven bias positioned at active wobbler shaft outward
Block, the active eccentric block is equipped with towards a side end face of driven eccentric block using spindle central as the arc groove in axle center, described
Driven eccentric block end to positioning pin is equipped with, the arc groove of active eccentric block is protruded into inside to positioning pin in the axial direction, actively eccentric
The radial side shoulder of block is fixed with removable relief panel, and when active eccentric block is aligned with the shoulder of driven eccentric block, pressing plate is pushed down
The ipsilateral driven eccentric block shoulder of active eccentric block, at this point, the positioning pin is located at below the side shoulder, and positioning pin
It extend into end position of the arc groove below the side shoulder.Motor is rotated towards one of direction counterclockwise or clockwise
When, the positioning pin in driven eccentric block withstands on the arc groove end under ipsilateral active eccentric block shoulder, and two pieces of wobbler shafts are to weight
It closes, generates 100% vibration force, when motor is rotated towards other direction, since inertia deflects, positioning pin is withstood on driven eccentric block
The end side of active eccentric block arc groove, make two pieces of eccentric blocks have angle in axial view angle operation, generate compared with
Low vibration force realizes vibration force of motor during single use and adjusts, solves and shake in vibrating motor use process
The difficult problem of power adjustment；Realize that structure is simple, it is reliable and stable.
As further improving and supplementing to above-mentioned technical proposal, the invention also includes following additional technical features.
