Embodiment 1:

Fig. 1, Fig. 3, Fig. 5, Fig. 8 have provided present embodiment 1 figure.Referring to Fig. 1 and Fig. 3, driver is made up of casing 1, hollow fork 2, direction position transducer 3, anti-dazzling screen 4, magnet hold-down support 5, the permanent magnet 6 that is connected with hold-down support, air core coil 7, air core coil 7 is fixed in the hollow fork 2, hollow fork 2 one ends are connected with cabinet wall by movable rotation-shaft 8, the other end stretches out outside the casing, and control circuit board 9 is fixedly mounted in the casing 1.

Referring to Fig. 5 and Fig. 8, the present embodiment driver is like this work: hollow fork 2 by the M position when swing the G position, permanent magnet 6 passes the hollow parts 10 in the hollow fork, after hollow fork 2 swings to position F and air core coil 7 when being in the position of leaving permanent magnet 6, anti-dazzling screen 4 just in time passes direction position transducer 3 (optoelectronic switch), the detected signal triggering monostable flipflop of direction position transducer this moment, its output pulse makes air core coil 7 acquisition pulse currents and produces a pulsed magnetic field different with permanent magnet polarity (if the ultra-Right N utmost point of left S, then another is the ultra-Right S utmost point of left N) through drive circuit.According to heteropole inhale mutually, the principle of homopolar-repulsion, fork 2 fork right side when leaving permanent magnet 6 that air core coil 7 is housed is relative with the permanent magnet left side, promptly obtaining a repulsive force identical with its direction of motion is impulse force, this impulse force upwards pushes away fork 2 to the upper left side and makes fork 2 arrive extreme higher position G once, and fork 2 is moving to backswing then.When fork process F position, the detected signal of direction position transducer this moment then triggers another monostable flipflop, its output pulse makes air core coil 7 obtain pulse current again and produces a pulsed magnetic field different with permanent magnet polarity through drive circuit, fork 2 fork left side when leaving permanent magnet 6 that air core coil 7 is housed is relative with the permanent magnet right side, obtaining a repulsive force identical with its direction of motion is impulse force, and this impulse force pushes away fork 2 and makes fork 2 arrive another side extreme higher position H once to right.Control circuit constitutes by DC power supply 14, direction position transducer 3, monostable flipflop 15 with drive circuit 16 that the monostable flipflop output joins.The input of monostable circuit and direction position transducer 3 join, and the output of drive circuit and air core coil 7 join.Circuit block diagram is seen Fig. 8.The available shaft seating 8 in fork 2 upper ends is fixed on the top in the casing, but fork 2 stage casing fixation hollow coil 7 and anti-dazzling screens 4, and fork 2 lower ends are then stretched out casing and are used for connecting pendulum mass outward, transmit kinetic energy to pendulum mass, swing continuously to keep pendulum mass.Permanent magnet 6 and direction position transducer 3 can be fixed on fork equilbrium position, casing middle part one side, and its locations of structures is referring to Fig. 1.(also permanent magnet 6 installation site with air core coil 7 can be exchanged, but permanent magnet 6 can both pass air core coil 7 will guarantee the each swing of fork 2 time.) direction position transducer 3 installation sites should be fixing with the cooperation of anti-dazzling screen 4 length, only when swing process hollow core coil leaves permanent magnet, the detected signal of direction position transducer just can trigger monostable flipflop, and its output pulse makes air core coil obtain electricity and produces a pulsed magnetic field different with permanent magnet polarity through drive circuit.According to there is a natural attraction between the sexes, the principle that the same sex is repelled each other, the fork that air core coil is housed all can obtain an impulse force (repulsive force) identical with its direction of motion at every turn when leaving permanent magnet.This thrust passes to pendulum mass by the connection of fork lower end, makes pendulum mass constantly obtain kinetic energy and keeps its periodic wobble.Pass to pendulum mass (as hammock, swing, rocking chair and shaking table etc.) by the fork lower end, make the pendulum mass swing, pendulum mass constantly repeats above-mentioned action, then constantly obtaining impulse force makes pendulum mass keep its periodic wobble, the impulse force that pendulum mass obtains pushes away the action of swing like the people, in each hunting period, all execute a thrust,, keep its constant amplitude periodic wobble with the kinetic energy rejection of compensation pendulum mass to pendulum mass.If normally the user wants to stop when waving, only need apply a resistance to pendulum mass, the amplitude of oscillation of fork is reduced to can not be by the perception of direction position transducer institute, and air core coil just can not get electric generation magnetic field, and pendulum mass can stop swinging gradually because of can not get thrust.

Embodiment 2:

Fig. 2, Fig. 9 have provided the utility model embodiment 2 figure.Present embodiment 2 is basic same with embodiment 1, not existing together is the permanent magnet 6 that all is provided with direction position transducer 3, anti-dazzling screen 4, magnet hold-down support 5 on fork 2 both sides, is connected with hold-down support, two magnet unicoil (or twin coil) the symmetrical structure modes of this employing are worked, if unicoil then needs to change respectively the sense of current that (control) flow to coil to change its polarity of the magnetic field when fork swings,, twin coil make the polarity of the magnetic field of two coils generation opposite if then need switching on respectively when fork swings.Because coil both sides permanent magnet same polarity is relative, so as long as the coil electricity between two magnets, the magnetic field of its generation all has can a side inhales a side mutually and repels each other, thus the impulse force multiplication that fork is obtained.Also can in control circuit, increase timer 18, pressure sensor 13 and power control circuit 17, timer is made up of counter and delay circuit, its input and monostable flipflop output join, when monostable flipflop output pulse reaches that counter imposes a condition or the no pulse time reaches and sets when requiring, timer all can be cut off the electricity supply by power control circuit, not only energy-conservation but also safety.

Embodiment 3:

Fig. 4 has provided the utility model embodiment 3 figure.Present embodiment 3 is basic same with embodiment 1, and not existing together is that installation site with direction position transducer 3, anti-dazzling screen 4 has exchanged, and direction position transducer 3 is installed on the fork 2 with the fork swivel motion of coming together, and that anti-dazzling screen 4 is fixed in the casing is motionless.

Embodiment 4:

Fig. 6, Fig. 7, Fig. 9, Figure 10 have provided the utility model embodiment 4 figure.Originally executing example 4, to be applied to swing 11 with the utility model be that example illustrates further.Adopt single magnet single coil structure in the present embodiment, the control circuit structured flowchart is seen Fig. 9, and circuit theory diagrams are seen Figure 10.Its direction position transducer is made of jointly light-emitting diode D1 and photosensitive tube BG-1, BG-2.Two monostable flipflops are made of jointly IC1 (CD4013), C4-1, R4-1, C4-2, R4-2 respectively.Timer is made up of counter IC2 (CD4024) and delay circuit triode BG2, BG3, BG4, capacitor C 5, resistance R 9 etc., and K2 is a timing selecting switch.DC power supply can be selected existing goods for use.Power control circuit is made up of relay J 1, J2, resistance R 1, R2, capacitor C 3, triode BG1, BG4 etc.Pressure sensor 13 (K1) adopts the fine motion pressure switch and is arranged on shelter, chair bottom.Air core coil 7 (L1) is arranged on the fork middle part and can be passed by permanent magnet when fork is swung.It is outer and link to each other with yaw bar 12 on being fixed on the swing suspension rod that casing is stretched out in the fork lower end.Drive circuit is made up of BG5-1, BG5-2 triode.

The course of work:

If do not connect DC power supply, fork is fixed on the fork middle part when swinging with swing air core coil L1 does not have electricity all the time, can not produce magnetic field, so fork can not get thrust, and swing can stop swinging gradually.After connecting DC power supply, make the fine motion pressure switch K1 closure that is installed in the chair bottom on the swing if nobody is sitting in, then power control circuit can not start, and fork just can not obtain thrust in swing process.This moment is if take on swing, make fine motion pressure switch K1 closure, then infrarede emitting diode D-1, D-2 work, direct current from DC power supply charges to capacitor C 3 through capacitor C 3, resistance R 2, triode BG1, its charging current makes triode BG1 conducting, relay J 1 adhesive, J1 normally opened contact closure.A part of direct current is through the J1 contact, and capacitor C 5, resistance R 9, triode GB4 charge to capacitor C 5, thereby cause the BG4 conducting, relay J 2 adhesives, and the J2 contact is also closed.The very fast meeting of J1 finishes triode BG1 by discharging because of capacitor C 3 chargings.BG1, BG2, BG3, BG5-1, BG5-2 end at this moment, and the BG4 conducting is waved magnetic driver and is in holding state.This moment, then J2 also can make partly dead electricity of control circuit because of capacitor C 5 chargings finish triode BG4 by discharging after a period of time as if the untimely swing that shakes.If begin to shake swing at this moment, the air core coil L1 that then is fixed on the driver fork also can swing back and forth along fixation locus together.Because two monostable flipflops all adopt rising edge to trigger, and photosensitive tube BG-1, BG-2 is installed in same position, therefore swing and during to position G from equilbrium position M when fork through position F (air core coil overlaps with permanent magnet), BG-1, two photosensitive tubes of BG-2 all end because of the blocking of anti-dazzling screen that is fixed on the fork, cause two monostable flipflop input IC, (CD4013) 3 pin current potentials descend, 11 pin current potentials rise, this rises and does not have (current potential) to trigger by C4-2, a monostable flipflop of R4-2 decision pulse length, positive pulse of its output IC1 (CD4013) 13 pin output, this pulse one tunnel flows to driving tube BG5-2 through R5-2 makes the air core coil L1 energising that is fixed on the fork produce the ultra-Right S pole field of left N, because this moment, fork was in by position F in the swing process of G position, therefore fork the right S pole field is just in time in the face of the S pole field on the permanent magnet left side, makes fork obtain left an impulse force according to principle of same-sex repulsion; Another road R6 that flows through makes triode BG2 conducting, discharges capacitor C 5 electric charge of depositing, and prolongs delay time, keeps the J2 adhesive.Fork will be swung to low order end position H from high order end position G behind this end-of-pulsing, anti-dazzling screen is ineffective through position F the time, photosensitive tube BG-1, the BG-2 conducting, cause the input 11 pin current potentials of two monostable flipflops to descend, 3 fall current potential rises, this rising edge (current potential) has triggered by C4-1, another monostable flipflop of R4-1 decision pulse length, its output IC1 (CD4013) 1 pin output-positive pulse, this pulse one tunnel flows to driving tube BG5-1 through R5-1 and passes the identical ultra-Right S pole field of left N of air core coil L1 energising generation, because this moment, fork was in by position F in the swing process of position H, therefore the N utmost point magnetic on the fork left side is just in time in the face of the N utmost point magnetic on permanent magnet the right, passes fork according to principle of same-sex repulsion to obtain-to the right impulse force; Another road is supplied with counter through IC2 (CD4024) 1 pin and is done timer counter usefulness.Because fork come what may, as long as all can obtain an impulse force identical immediately after swinging to position F (air core coil overlaps with permanent magnet) with its direction of motion.Therefore the swing that links to each other with fork will be kept the constant amplitude periodic wobble because of constantly obtaining thrust.When the pulse number that is received as counter IC2 satisfies the selected condition of timing switch K2, the high level signal of IC2 output makes triode BG3 conducting through K switch 2, resistance R 7, BG4 ends, relay J 2 discharges, each control circuit dead electricity is not worked, and swing will reduce the amplitude of oscillation gradually until stopping swinging.If the time of setting not then the user want to stop, only need to apply-resistance to swing, make the amplitude of oscillation of fork (being swing) not reach position F, the photosensitive tube on the direction position transducer can not trigger monostable flipflop, air core coil L1 just can not produce magnetic field, and fork just can not get thrust.Treat that capacitor C 5 charging end back J2 promptly discharge in the delay circuit, each control circuit dead electricity is not worked, and swing stops swinging.

Waving magnetic driver also can adopt two magnet unicoils or twin coil symmetrical structure mode to work.If adopt twin coil only to need change the driving tube BG5-2 collector electrode line among Figure 10 into 2 by 1, with R3-2 and photosensitive tube BG-2 location swap and be installed on Fig. 2 relevant position and get final product.The course of work: behind the power initiation, when fork is swung to the right and during through the left end permanent magnet from high order end, photosensitive tube BG-1 on the left direction position transducer is because of the conducting of leaving of left side anti-dazzling screen, monostable flipflop input IC1 (CD4013) 3 pin current potentials are uprised by low, trigger is triggered and 1 pin output-positive pulse, this pulse one tunnel flows to driving tube BG5-1 through resistance R 5-1 makes L1 get the magnetic field of the ultra-Right S utmost point of the left N of electric generation, this magnetic field and left side permanent magnetic field body produce repulsive force, produce attraction thereby make fork obtain increasing 1 times impulse force to the right with the right side permanent magnet.Another road is made counting and timing for counter and is used; When fork from low order end during to left end swing and through the right-hand member permanent magnet, the conducting of photosensitive tube BG-2 on the direction position transducer of the right, another monostable flipflop output IC1 (CD4013) 13 pin are also exported-positive pulse, this pulse one tunnel flows to driving tube BG5-2 through resistance R 5-2 makes L2 get the opposite polarity magnetic field of electric generation L1, be the magnetic field of the ultra-Right N utmost point of left S, this magnetic field and right side permanent magnet produce repulsive force, produce attraction with the left side permanent magnet, thereby make fork obtain increasing 1 times impulse force left.Another road through resistance R 6, flow to triode BG2 and make its conducting, discharge capacitor C 5 electric charge of depositing, prolong delay time, keep the J2 adhesive.So move in circles.

If adopt unicoil to drive, then needing when fork swings respectively, control break flows to the sense of current of air core coil to change polarity of the magnetic field.Its operation principle is identical with twin coil, and the change of control circuit repeats no more here because length is limit.

The various embodiments described above are that foregoing of the present utility model is further described, but this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to the foregoing description.All technology that realizes based on foregoing all belong to scope of the present utility model.
