Description
Technical field
The invention belongs to electrical equipment technical fields, more particularly to a kind of three station permanent magnet mechanisms.
Background technology
In commercial Application, a large amount of driving mechanisms for needing to have there are three operating position.For convenience of explanation, three are defined
Operating position is respectively upper station, middle station and lower station.It is most difficult to be accomplished that and accurately positions and locate on middle station position
In stable state.
Chinese patent CN102789928B discloses one kind《Driving mechanism》, it is that there are three the permanent magnetic operating machines of station for tool
Structure.The defect of the invention is：Dynamic iron core is by the same line by middle station to lower station by upper station to middle station and dynamic iron core
Circle driving.This will appear following situation：Dynamic iron core by upper station to middle station when, lower driving coil, which is powered, generates electromagnetic force, drives
Dynamic dynamic iron core movement；When station needs its stopping in dynamic iron core arrival, suction and mechanism resistance resistance that only permanent magnet generates
Stop iron core continues to move ahead, and the inertia force of electromagnetic force and movement that driving coil generates still drives dynamic iron core to continue to move ahead.Institute
With dynamic iron core is easy to cross the through lower station in middle position.It is similar, when dynamic iron core by lower station to middle station when, it is also possible to
Dynamic iron core crosses the through upper station position in centre position.Even if the electromagnetic force that coil is generated, dynamic iron core inertia force, mechanism hinder
Power, the various power accurate balances such as suction of permanent magnet, allow iron core to be parked on middle station, but by upper station to middle station
The dwell point of dwell point and lower station to middle station is not same point, and two dwell points are staggered, i.e. the stop in middle station
It puts and does not know.
Chinese patent CN102064600A discloses one kind《Tristable differential permanent magnetic operating mechanism》.The tri-steady mechanism
It is that two springs are increased on bistable-state permanent magnet mechanism, moving iron core by the two spring handles maintains middle station position.But forever
The magnetic force of magnet is not stable state to dynamic iron core, and one has external force position that will move.Dynamic iron core each run is wanted to middle station
It is just stopped by multiple oscillation.So this mechanism is not stable state in middle station, it is the three-stable state of vacation.
Chinese patent CN102610407A discloses one kind《Three-station bistable permanent magnet mechanism》.Although mechanism design is skilful
It is wonderful, but disadvantage is also apparent：1, because dynamic iron core is divided into two sections, when dynamic iron core is run by middle station to lower station, separation
Two sections of dynamic iron cores be by permanent magnet magnetic attraction together, when mechanism occur clamping stagnation resistance increase when, by magnetic attraction one
The two sections of dynamic iron cores risen can detach, this causes unreliable；2, permanent magnet is mounted on dynamic iron core, moves iron core great, frequent
Impact under the magnetic force of permanent magnet may be made to decline, or even frangible permanent magnet is made to go to sticks and staves；3, complicated, manufacture is difficult.
Chinese patent CN20545579U discloses one kind《A kind of three-stable state permanent magnet mechanism》.The patent is still dynamic iron core
It is divided into two sections, is equivalent to and puts together two bistable permanent magnet mechanisms are back-to-back, each permanent magnet mechanism makes a movement, looks
Seemingly it is combined into the movement of three-stable state permanent magnet mechanism.But the impetus station of lever is two, is not three stations.
