The operation principle of said structure is, described permanent magnet is the intrinsic magnetic field direction, diagonal angle armature plate magnetic polarity is identical, set the first position of an armature component herein: two armature contacts contact with yoke, coil moment, coil yoke assembly produced magnetic field by behind the direct current, but the intrinsic magnetic field direction of magnetic direction and armature component is when opposite, this moment, the repulsive force of the magnetic force that armature component is subjected to was identical with the attraction direction, made a concerted effort to promote upwards (or the downwards) motion of armature component straight line; Move to when in addition two armature plate contacts contacts with yoke and stop, the direct current by coil disconnects at this moment, but owing to the effect of permanent magnet, armature component still can keep current location.In like manner, coil moment, coil yoke assembly produced magnetic field by behind the direct current in the other direction, but the intrinsic magnetic field direction of magnetic direction and armature component promotes (or the upwards) motion downwards of armature component straight line when opposite, gets back to first position; This moment, the direct current by coil disconnected, but because the effect of permanent magnet, armature component still can keep current location.By the evolution of armature component, realized the purpose that makes path be communicated with or disconnect.
In order to reach the identical purpose of armature plate contact, diagonal angle magnetic polarity, the armature plate in the described armature component is set to several versions down:
1, two straight sheet type
Two armature plates are the parallel distribution of "=" font, are bumped into two blocks of opposite permanent magnets of direction separately, and this moment, the magnetic pole of two armature plates was opposite, then reached the identical purpose of armature plate contact, diagonal angle magnetic polarity.The relative position of two armature adopts plastic injection-moulded or non-magnetic conductive metal spare riveting to fix.
2, four straight sheet types
Two parallel distributions of permanent magnet that direction is opposite, each connects two armature plates stretches, and totally four armature plates reach the identical purpose of armature plate contact, diagonal angle magnetic polarity.The relative position of four armature adopts plastic injection-moulded or non-magnetic conductive metal spare riveting to fix.
3, four L types
Two parallel distributions of permanent magnet that direction is opposite, each connects the armature plate of two L types stretches, and totally four armature plates reach the identical purpose of armature plate contact, diagonal angle magnetic polarity.The relative position of four L type armature adopts plastic injection-moulded or non-magnetic conductive metal spare riveting to fix.
4, two X type medium spacings
Two armature plates are " X " and distribute, and every armature plate links to each other in the centre, is bumped into two blocks of permanent magnets that direction is opposite in the middle of armature plate, reaches the identical purpose of armature plate contact, diagonal angle magnetic polarity.The relative position of two armature adopts plastic injection-moulded or non-magnetic conductive metal spare riveting to fix.
5, two X type bilateral types
Two armature plates are " X " and distribute, and every armature plate links to each other in the side, is bumped into two blocks of permanent magnets that direction is opposite in the middle of armature plate, reaches the identical purpose of armature plate contact, diagonal angle magnetic polarity.The relative position of two armature adopts plastic injection-moulded or non-magnetic conductive metal spare riveting to fix.
6, two X type both sides containing edges are box-like
Two armature plates are " X " and distribute, and every armature plate links to each other in the side, and two armature plates are U type containing edge separately and close, and joggled part position central longitudinal reaches the identical purpose of armature plate contact, diagonal angle magnetic polarity to being bumped into a permanent magnet.The relative position of armature adopts plastic injection-moulded or non-magnetic conductive metal spare riveting to fix.
Owing to adopted the reciprocating traverse of straight line, structure is simpler, overall volume is littler, in order to make these parts further enlarge the inner space, the present invention can also adopt flat coil, form the flat coil yoke of U type assembly, it is characterized in that changing traditional cylindrical coil into flat coil, the armature component direction of motion is perpendicular to the plane of coil axis and yoke center line composition.Can also adopt two flat coils, form the flat twin coil yoke of O type assembly, to produce stronger magnetic force, and then the stronger reciprocal length of run power of generation, the flat coil yoke of O type assembly is achieved in that the yoke both sides of O type is twined with the single line circle that the diagonal of coil links to each other, and cornerwise in addition two coil open ends link to each other with power supply respectively, during energising, the identical magnetic energy of both sides coil polarization.Twin coil produces two magnetic poles for being connected in parallel at the armature two ends, and the magnetic energy of generation is monocoil 2 times, the plane that the direction of motion of armature is formed perpendicular to the twin coil axis.
The present invention is because the armature component length of run is that straight line and the repulsive force that is subjected to simultaneously are identical with the attraction direction, and length of run power is big, and is simple and compact for structure, good anti-vibration, and anti-electromagnetic interference capability is strong, and it is reliable to be swift in motion, and volume is little.
