Abstract
A kind of pulsed electromagnetic drive mechanism of electric lock, constitute by magnetic circuit element etc., the tumbler two large divisions who is divided into fixture and can rotates with respect to fixture around the shaft, have two variable working magnetic gaps between fixture and tumbler at least, current flux passes less magnetic gap and tumbler is rotated and drives the locking bolt motion on the contrary with permanent magnetic flow direction in this magnetic gap during energising.This mechanism can use powered battery.The electric supply installation of a kind of electric lock pulsed drive mechanism is made of oscillator, transformer, rectifier, energy-storage capacitor, discharge circuit etc., can effectively improve the driving power of electric lock.
Description
The application belongs to the lockmaking field, relates to electric lock (claiming electronic lock or electric control lock again), particularly relates to a kind of pulsed electromagnetic drive mechanism of electric lock and the electric supply installation of a kind of electric lock pulsed drive mechanism.
Lockset all has the driving mechanism that is used for driving the locking bolt motion, and for mechanical lock, driving mechanism is a mechanical mechanism, is driven by manpower; For electric lock, driving mechanism is a motor drive mechanism, by driven by power.
The driving mechanism of electric lock has two types: a class is an electric driving mechanism, and this class mechanism exists because of motor has brush, also needs complicated reduction gearing mechanism, so the life-span is shorter, reliability is relatively poor.Another kind of is electromagnetic drive mechanism, this mechanism is by magnetic circuit element (soft, hard magnetic material, ironcore choke etc.) constitute magnetic circuit, drive by electromagnetic force, magnetic circuit element in the magnetic circuit constitutes two big parts again: fixture and movement parts, to form by one or more magnetic circuit element, and its fixture is installed on the lock housing, movement parts directly or by transmission mechanism links to each other with locking bolt, and can be under the effect of electromagnetic force with respect to kinematic mount with the driving locking bolt.Electromagnetic drive mechanism exists because of no motor, and also very simple even transmission mechanism has, reliability is also very high.
The electromagnetic drive mechanism of electric lock commonly used is solenoid moving-iron type mechanism (great majority relates to the books and the magazine of electric lock and all introduced this mechanism) at present.The fixture of this mechanism is made up of electromagnetic components such as solenoid, fixed iron cores, and is fixed on the lock housing.Movement parts is the moving iron core of the suitable shape made by soft magnetic materials (as soft iron), can in solenoid, move back and forth, one latch is arranged to limit its stroke on it, locking bolt just directly links with movement parts (also have just with long movement parts directly as locking bolt), and back-moving spring also is housed in the solenoid.Its course of work is: after " opening " lock signal arrives, and the solenoid energising, its electromagnetic force makes movement parts be inhaled into solenoid, and movement parts drives locking bolt retraction lock housing, and back-moving spring is compressed, and at this moment lock has just been opened.Make the lock locking only need solenoid is cut off the power supply, electromagnetic force disappears, back-moving spring will eject solenoid with movement parts, drive locking bolt stretch out lock housing will locking, coil is switched on always when " opening " the lock state because of this being locked in, so power consumption is very big, can not use dry cell power supply, need to cooperate storage battery power supply with AC power.
United States Patent (USP) 3792888 and 3897093 has adopted the double solenoid electromagnetic drive mechanism, its movement parts comprises two movable cores and the tumbler that is promoted and can be rotated by movable core in a rotating shaft, this tumbler is under reciprocating movable core promotes, can sway one on the other as seesaw, thereby drive the dead bolt motion, this mechanism carries on as before and belongs to the solenoid electromagnet mechanism, so power consumption is still bigger.Chinese patent 912075716 " electronic lock breech lock " buries the movement parts that magnet is housed with whether magnetizing of the ironcore choke in the fixture and moves back and forth, this mechanism is a kind of electromagnetic drive mechanism with stable " magnetic self-locking " state, when lock is in " closing " attitude, magnet and magnetic bobbin core adhesive mutually, mechanism's self-locking; And when lock when being in " opening " attitude, magnet and ironcore choke are separated, and that can realize locking closes automatically.The electricity consumption signal controlling was comparatively desirable when this mechanism " drove " lock at need, and power consumption economizes, but mechanism will be difficult to distinguish electromagnetic force and permanent magnetism power this two kinds " suction " when need " close " lock, and in other words, the signal of telecommunication was uncertain to the control of state when this mechanism " closed " lock at need.
Task of the present invention is to disclose a kind of electromagnetic drive mechanism that can battery-powered electric lock.
The present invention realizes in the following manner: this is a kind of magnetic circuit elements such as magnetic circuit element such as soft magnetic bodies (soft iron, silicon steel sheet etc.), hard magnetic body (magnet), ironcore choke that include, also be the magnetic circuit mechanism that constitutes by fixture and movement parts two big parts, see the schematic diagram of accompanying drawing 1-4.In Fig. 1-4, the 1st, fixture is made of magnetic circuit elements such as soft iron, magnet, ironcore chokes; The 2nd, movement parts is that (2 can be made of magnetic circuit elements such as soft iron rods a tumbler, and this moment, mechanism was called moving-iron type mechanism; Can be that the master constitutes by magnetic circuit elements such as magnet also, this moment, mechanism be called moving-magnetic type mechanism; Can also be that the master constitutes by magnetic circuit elements such as ironcore chokes, this moment, mechanism be called moving-coil type mechanism); The 3rd, rotating shaft, available metal car system forms, and its position is at 2 a middle part or an end; Tumbler 2 can be around the shaft 3 rotates with respect to fixture 1.Magnet is essential magnetic circuit element in the mechanism, and in order to produce permanent magnetic magnetic flux φ m, in Fig. 1-4, φ m passes the two ends, the left and right sides of fixture 1 and tumbler 2 simultaneously, and the working magnetic gap of establishing between 1 and 2 left ends is X
1, the working magnetic gap between 1 and 2 right-hand members is X
2(because of X
2Can be with respect to 1 rotation, so X
1And X

1And X
2Permanent magnetic magnetic flux be respectively φ m

1＞Fm
2, the left end of tumbler 2 will move down, and more to moving down Fm
1Bigger, Fm
2Littler, this just makes 2 left end quicken to move down, because 2 also rotate in rotating shaft 3, therefore 2 right-hand member moves simultaneously, until the 2 contacted extreme positions of left end that turn to its left end and fixture 1, at this moment because of X

1Firmly the left end of tumbler 2 is adsorbed in the left end of fixture 1, this moment, mechanism was in a stable status, and as shown in Figure 1, we establish this state is " B " state.Be added on tumbler 2 if any external force this moment, is provided with a downward power F and is added on 2 right-hand member and F＞(Fm
1-Fm
2), 2 right-hand member is moved down, as long as its displacement does not reach and makes X
2〉=X
1, then after external force is removed, because of Fm
2＜Fm
1, 2 also can be returned to original stable state " B " state voluntarily, and promptly 1 and 2 left end is attached together, if F＜(Fm
1-Fm
2), then mechanism to keep " B " state constant, we are called the magnetic self-locking state of mechanism this stable state of mechanism, " B " state also is called " B " stable state.
Situation when the ironcore choke in giving magnetic circuit passes to operating current I is seen Fig. 2 (ironcore choke in the magnetic circuit also is essential magnetic circuit element), this electric current I will produce induction magnetic flux φ d in magnetic circuit, its direction is determined by right-hand rule in the law of electromagnetic induction or right-hand screw relation.If make the magnetic flux φ d that produces when passing to electric current I in the coil pass magnetic gap x less among Fig. 1 simultaneously

2Also increase, tumbler 2 quickens to rotate, until the 2 contacted extreme positions of right-hand member that forward its right-hand member and fixture 1 to, and at F
2Effect firmly inhale mutually down with 1 right-hand member, this moment, mechanism was in another stable magnetic self-locking state, we claim that this state is " K " state or " K " stable state.If the magnetic gap between 1 and 2 left ends is x at this moment

1' effect under tightly be adsorbed onto together, this moment, mechanism got back to first stable magnetic self-locking state again, i.e. " B " stable state among Fig. 1, this stable state can not change because of the disappearance of electric current-I yet.If after reversing the current-I disappears, pass to electric current-I to coil again, then because of at less magnetic gap x
1In φ m is arranged
1+ φ d
1, can only make between 1 and 2 left ends suction bigger, mechanism still remains on " B " stable state.
By last we can obtain two conclusions, our first conclusion is: in this mechanism, when mechanism is in " B " stable state, pass to once or during once above forward current I, mechanism can be changed into " K " stable state to ironcore choke; If to coil pass to once or once above reversing the current-during I, mechanism's state is constant.When mechanism is in " K ", during stable state, pass to once or during once above forward current I, mechanism's state is constant to ironcore choke, when pass to once to coil or reversing the current once-during I, mechanism can be changed into " B " stable state.We have drawn the form of Fig. 5 thus.
By the form of Fig. 5 as can be known: no matter mechanism was in " B " state or " K " state originally, as long as we pass to forward current I to ironcore choke, mechanism just will be " K " shown in Figure 3 state; If ironcore choke is passed to reversing the current-I, mechanism just will be " B " shown in Figure 1 state.Therefore, for the mechanism shown in Fig. 1-4, we can control its state by the sense of current of controlling its coil.If drive the locking bolt of electric lock with the tumbler among Fig. 1-4 2, such as locking bolt directly is contained on the tumbler 2, tumbler 2 can drive the locking bolt action, as shown in Figure 6.
In Fig. 6, the 1st, fixture, the 2nd, tumbler, the 3rd, rotating shaft, the 4th, locking bolt, the 5th, lock housing.
The mechanism of Fig. 6 is in " B " stable state identical with Fig. 1, from Fig. 6 as seen, this moment, locking bolt 4 was stretched out by lock housing 5, lock is to be in " closing " lock state, when the ironcore choke in giving mechanism passes to forward current I, as can be seen from Figure 5, mechanism will be converted to " K " state, promptly this moment locking bolt 4 retraction lock housings 5, promptly lock " being opened " has opened.
In Fig. 6, locking bolt 4 is directly to link to each other with tumbler 2, and this moment, 4 movement locus was one section circular arc, and when the radius of circular arc was big, 4 movement locus just was similar to straight line, i.e. 4 reciprocating motions that can do to be similar to.As require locking bolt 4 to do more accurate the reciprocating motion, and a gear can be fixed in the rotating shaft 3, and drive the locking bolt of tooth with this gear, just rotatablely moving of tumbler can be changed into the reciprocating motion of locking bolt.
Our second conclusion is: this mechanism can drive with pulse current.When needing " opening " lock, coil is passed to the direct impulse electric current I, mechanism can enter " K " state, and lock just " has left "; When needing " closing " lock, coil is passed to reverse impulse electric current-I, mechanism can enter " B " state, and lock just lock " has closed ".Drive this mechanism with pulse current and can reduce power consumption effectively.
Therefore, this mechanism is a kind of pulsed electromagnetic drive mechanism of low power consumption electric lock, and the electric supply installation of this mechanism can be used dc source, directly powers as dry cell.Its power supply circuits are seen accompanying drawing 7,8.In Fig. 7,8, the 1st, the ironcore choke of electric lock The Impact Drive Mechanism; The 2nd, dc source (as dry cell etc.); 3, the 4th, switch, as mechanical switch, the contact of relay or tongue tube, electronic non-contact switch (as being operated in transistor, controllable silicon of on off state etc.).Fig. 7,8 is the bipolarity power supply circuits.Fig. 7 is the bipolarity power supply circuits that used two groups of power supplys, and during the switch 3a conducting of Fig. 7, the right-hand member of coil 1 joins through the positive pole of 3a and power supply 2a, and forward current I flows into 1 right-hand member, and mechanism be " K " stable state, locks " opening " and opens; During the switch 3b conducting of Fig. 7, the right-hand member of coil 1 joins through the negative pole of 3b and power supply 2b, and reversing the current-I flows into 1 right-hand member, and mechanism be " B " stable state, and lock is locked " closing ".Fig. 8 is for using the bridge connection bipolarity power supply circuits of one group of power supply, and during switch 3a, the 3b of Fig. 8 conducting simultaneously, the right-hand member of coil 1 joins through the positive pole of 3a and power supply 2, left end joins through the negative pole of 3b and 2, forward current I flows into 1 right-hand member, and mechanism is " K " stable state, and lock " opening " opens; During switch 4a, the 4b of Fig. 8 conducting simultaneously, the right-hand member of coil 1 joins through the negative pole of 4b and power supply 2, and left end joins through the positive pole of 4a and 2, and reversing the current-I flows into 1 right-hand member, and mechanism is " B " stable state, and lock is by lock " closing ".
The characteristics of Fig. 7 power supply circuits have been to use two groups of power supplys, so the utilization rate of power supply is lower.The characteristics of Fig. 8 power supply circuits are with bridge circuit single supply to be converted to bipolar power supply, power utilization rate height, but control circuit is complicated.For solving this contradiction, power supply circuits are simplified, whether the mechanism that we inquire into accompanying drawing 1-4 earlier can also power with the unipolarity power supply.
For the mechanism of accompanying drawing 1-4, when passing to pulse current, as satisfying: 1, the current flux in the ironcore choke passes magnetic gap less in the working magnetic gap and opposite with permanent magnetic flow direction in this magnetic gap; 2, also pass big magnetic gap and identical, mechanism is rotated with permanent magnetic flow direction in this magnetic gap.As only satisfying 1 and do not satisfy 2, mechanism can rotate by the same manner, though at this moment driving power is less, can simplify power supply circuits, describes below in conjunction with accompanying drawing.
In Fig. 9,10, the 1st, fixture, the 2nd, tumbler, the 3rd, rotating shaft.If mechanism is in " B " stable state shown in Figure 1, as in the ironcore choke of mechanism, passing to pulse current, at less magnetic gap x
1The middle current flux φ d that produces

1With φ m
1Direction is opposite, and φ m
1-φ d
1→ 0, and no current magnetic flux in 1 and 2 the right-hand member magnetic gap, only persevering magnetic magnetic flux φ m
2, then because of the electromagnetic attraction F between 1 and 2 left end
1→ 0, tumbler 2 will be at the permanent magnetic magnetic force of right-hand member Fm
2Effect under clockwise rotate, see Fig. 9, the right-hand member adhesive until 1 and 2 is to entering " K " stable state shown in Figure 3 together.Make the less magnetic gap x of Fig. 3 as passing to pulse current to coil once more
2' in current flux φ d
2Direction and φ ' m
2Direction opposite, shown in dotted arrow among Figure 10, and φ ' m
2-φ d
2→ 0.And permanent magnetic magnetic flux φ ' m in 1 and 2 left ends
1Size is constant, then because of the electromagnetic attraction F between 1 and 2 right-hand members
2→ 0, tumbler 2 will be between 1 and 2 left ends permanent magnetic magnetic force Fm
1Effect down inhour rotate, see Figure 10, the left end adhesive until 1 and 2 is got back to " B " stable state of Fig. 1 to together.
For above two kinds of type of drive, can compare in conjunction with Fig. 2 and Fig. 9, in the mechanism behind the coil electricity, the less magnetic gap x in its left side
1Middle total magnetic flux φ
1=φ m
1-φ d
1→ 0, total magnetic force F
1=Fm
1-Fd
1→ 0, the big magnetic gap x in its right side
2Middle total magnetic flux has φ for Fig. 2
2=φ m
2+ φ d
2=2 φ m
2, and Fig. 9 is had φ
2=φ m
2, promptly its driving force ratio of the type of drive of Fig. 2 Fig. 9 wants type of drive big but Fig. 9 to power with the unipolarity power supply, and Fig. 2 then needs the bipolar power supply power supply.
The unipolarity power supply circuits are seen accompanying drawing 11, in Figure 11, and the 1st, the ironcore choke of electric lock The Impact Drive Mechanism, the 2nd, dc source, the 3rd, switch is for having contact or noncontacting switch.If the current flux that ironcore choke 1a produces is φ d
1, the current flux that 1b produces is φ d
2, then as shown in Figure 9, in the 3a conducting, after the 1a energising, mechanism will be " K " stable state, lock " opening " opens; In the 3b conducting, after the 1b energising, mechanism will be " B " stable state, and lock is by lock " closing ".Obviously the power supply circuits of Figure 11 have only been used one group of power supply, and control circuit is also very simple.
For aforementioned electric lock pulsed drive mechanism, drive or drive with the power supply of unipolarity power supply no matter be with the bipolar power supply power supply, its current flux all passes magnetic gap less in the working magnetic gap and opposite with permanent magnetic flow direction in this magnetic gap, and this is the common trait of two kinds of type of drive of this mechanism (accordingly need with two kinds of power supply modes).Only when the big driving power of needs, it is suitable to adopt the bipolar power supply power supply to be only, at this moment current flux passes magnetic gap bigger in the working magnetic gap and identical with permanent magnetic flow direction in this magnetic gap simultaneously, and at this moment driving power can increase, but power supply circuits will become complicated.
Said mechanism has long, high reliability features of general electromagnetic drive mechanism life-span as a kind of pulsed electromagnetic drive mechanism of electric lock, and power consumption also economizes very much, can use the general dry battery power supply fully.
For this electric lock pulsed electromagnetic drive mechanism, its magnetic circuit is to be made of the magnetic circuit element in fixture and the tumbler, and parallel circuits is arranged, type such as bridge-type magnetic circuit, further describe below in conjunction with the embodiment of accompanying drawing 12-23.
In Figure 12-23, the 1st, ironcore choke, the 2nd, magnet, the 3rd, tumbler, the 4th, rotating shaft, the 5th, locking bolt, the 6th, lock housing, the 7th, iron yoke.The embodiment of Figure 12-19 is a parallel circuits mechanism, magnetic circuit element 1 wherein, and magnet 2, tumbler 3, iron yoke 7 grades have constituted parallel circuits mechanism.Its tumbler 3 is on a branch road of parallel circuits.Parallel circuits also can be described as differential magnetic circuit, and this is that its moving part (tumbler) is contained on the common magnetic circuit, and the magnetic deviation between the magnetic gap of every limit is had an effect because all there is the magnetic loop of two symmetries in general parallel circuits mechanism.Figure 12 is that its magnetic circuit is an exemplary embodiments of the electric lock pulsed electromagnetic drive mechanism of parallel circuits, in Figure 12, magnet 2 can be hard magnetic materials such as ferrite, aluminium nickel cobalt, an end of 2 is fixed with an iron yoke 7 of being made by soft magnetic materials such as soft irons, two ends of iron yoke 7 are fixed with ironcore choke 1a and 1b, the other end of magnet 2 has a rotating shaft 4, can form by metal car system, one tumbler 3 that can be made by soft magnetic materials such as soft irons is arranged in the rotating shaft 4, the position of rotating shaft 4 is at 3 middle part, and 3 can rotate on 4.In addition, locking bolt 5 is directly to be fixed on the tumbler 3.In Figure 12, locking bolt 5 is to reach outside the lock housing 6, and at this moment lock is to be in lock " to close " state (being " B " shown in Figure 1 stable state), permanent magnetic magnetic flux φ m
1Pass magnetic gap x less between 3 and 4 left ends
1, φ m
2Pass magnetic gap x bigger between 3 and 4 right-hand members
2, φ m
1The magnetic force Fm that produces
13 and 4 left end is pulled together, makes mechanism be in the magnetic self-locking state.The parallel circuits of Figure 12 has three branch roads of 1a, 2,1b, and its tumbler 3 is on the magnetic circuit element 2 in common magnetic circuit, and its rotation direction depends on two ends, 3 and 4 left and right sides magnetic gap x
1And x
2Between magnetic deviation, therefore, this mechanism also is an a kind of differential magnetic circuit mechanism.The seesaw that the motion mode of the tumbler 3 among Figure 12 as if child play can be that mid point moves one on the other with the axis of magnet 2 around its rotating shaft 4, therefore, can claim that again this mechanism is a twin coil list magnet list seesaw type mechanism.If the bipolarity power supply circuits with Fig. 7 or Fig. 8 are this mechanism's power supply, when then coil 1a, the 1b in giving mechanism passes to the pulse current I of the direction of arrow among the figure, according to right-hand rule in the law of electromagnetic induction or right-hand screw relation, the current flux φ d among the ironcore choke 1a
1Pass magnetic gap x less in the working magnetic gap
1And with this magnetic gap in permanent magnetic magnetic flux φ m
1Direction opposite, its total magnetic flux φ

2=φ m
2+ φ d
2, at x
2In total magnetic force F
2=Fm
2+ Fd
2=2Fm
2, see Figure 12, because of F
1→ 0, so tumbler 3 will be at F
2Effect under clockwise rotate its right-hand member and ironcore choke 1b is pulled together, mechanism enters another magnetic self-locking state, promptly " opens " state (" K " attitude shown in Figure 3) of lock, as seen from Figure 12, this moment locking bolt 5 with retraction lock housing 6, lock " being opened " opens.When passing to the reverse impulse electric current that the direction of arrow is opposite among Figure 12-I as coil 1a, the 1b that gives Figure 12 again, 3 rotate inhour, get back to " B " attitude shown in Figure 1, and the locking bolt among this moment Figure 12 stretches out lock housing 6 again, and lock is lock " closing " once more.As seen, the analytical method of Figure 12 analysis of mechanism method and the course of work and Fig. 1-4 mechanisms and the course of work are duplicate.
In analysis just now, two the ironcore choke 1a and the 1b of mechanism pass to forward current I or reversing the current-I simultaneously, need the bipolar power supply power supply circuits power supply with Fig. 7 or 8.If we are mechanism's power supply of Figure 12 with the unipolarity power-supplying circuit of Figure 11, and with the conduct of the coil 1a among Figure 11,12 " opening " locking wire circle, 1b is as " closing " locking wire circle, then when the switch 3a conducting among Figure 11,1a switches on (sense of current should be identical with direction shown in Figure 12 among the 1a), the current flux φ d among the 1a

2=Fm
2, tumbler 3 will be at F
2Effect under clockwise rotate, mechanism enters " K " state shown in Figure 3, the lock " opening " open.When the switch 3a conducting among Figure 11,1b switches on (sense of current should be opposite with direction shown in Figure 12 among the 1b), the current flux φ d among the 1b
2With permanent magnetic magnetic flux φ m
2Direction still opposite in the less magnetic gap between 3 right-hand member and 1b, tumbler 3 will be at F
1=Fm
1Effect down inhour rotate, enter " B " stable state shown in Figure 1, make lock lock " closing ".The above analytical method and the course of work and Fig. 9,10 the analytical method and the course of work are duplicate.
Mechanism shown in the accompanying drawing 13 is the derivation mechanism of Figure 12 mechanism, and the magnetic circuit element of Figure 13 mechanism, magnetic structure, analytical method and the course of work and Figure 12 are similar.The embodiment of Figure 13-19 has only drawn the magnetic structure figure of simplification and the direction of φ m and φ d, ironcore choke 1 judges around right-hand rule in the available law of electromagnetic induction or right solenoid relation among the figure, for the mechanism of Figure 13 with Fig. 7,8 bipolarity power supply circuits the time, the current flux φ d that produces behind its coil electricity

2Pass simultaneously big magnetic gap and with this magnetic gap in permanent magnetic magnetic flux φ d
2Direction identical, tumbler 3 will clockwise rotate in rotating shaft 4, its right-hand member break away from iron yoke 7c move down until with iron yoke 7d adhesive mutually, thereby finish the conversion of mechanism's state.Figure 13 is compared with Figure 12, and the position of rotating shaft 4 is the ends at tumbler 3, and the tumbler 3 in Figure 13 mechanism resembles the pendulum in the clock very much, still claim that the magnetic circuit mechanism of Figure 13 is a twin coil list magnet mono-pendulum type mechanism.This mechanism is the unipolarity power supply power supply of available Figure 11 also.
The mechanism of accompanying drawing 14,15 is that the another kind of Figure 12 mechanism derives from mechanism, and the magnet among Figure 12 2 and coil 1a, 1b are replaced with an ironcore choke 1 and two magnet 2a, 2b respectively, promptly becomes two magnet unicoil list seesaw type structures shown in Figure 14.Equally the magnet among Figure 13 2 and coil 1a, 1b are replaced with ironcore choke 1 and magnet 2a, 2b and then become the two magnet unicoil mono-pendulum type of Figure 15 mechanism.The analytical method of Figure 14,15 mechanisms and the course of work and Figure 12 and Figure 13 are similar.Unicoil mechanism can only power with bipolar power supply.
Figure 16 and Figure 17 are two kinds of more special parallel circuits mechanisms.In Figure 16, respectively there is a rotating shaft 4a and a 4b at the two ends of magnet 2, and the tumbler 3a and the 3b that can rotate around it respectively arranged on 4a and the 4b, and 3a and 3b also soft magnetic materials such as available soft iron make.Respectively there is an ironcore choke 1a and a 1b both sides of magnet 2, and the two ends of ironcore choke 1a and 1b can be associated with iron yoke 7a, 7b, 7c, 7d.In Figure 16, tumbler 3a, 3b inhale mutually with iron yoke 7a, 7b, as Figure 16 mechanism and Fig. 7,8 bipolar power supply are linked to each other, and then when coil 1a, 1b pass to forward current I, its current flux φ d
1Between 3a, 7a and 3b, 7b in the less magnetic gap with permanent magnetic magnetic flux φ m
1Direction opposite, and between 3a, 7c and 3b, 7d current flux φ d in the bigger magnetic gap
2With permanent magnetic magnetic flux φ m
2Direction is identical, sees Figure 16.This moment 3a with inhour rotate until with 7c adhesive mutually, 3b will clockwise rotate until with 7d adhesive mutually, thereby finished the transformation of mechanism's state.If pass to reverse impulse electric current-I for again this moment coil 1a, 1b, 3a, 3b will rotate once more and with 7a, 7b adhesive once more, mechanism gets back to state shown in Figure 16 again.The position of shaft 4a of Figure 16 mechanism and 4b is the end at movable piece 3a and 3b, so the mechanism of Figure 16 is a twin coil list magnet double pendulum type mechanism.Figure 17 mechanism is the derivation mechanism of Figure 16 mechanism, as Figure 17 mechanism and Fig. 7,8 bipolar power supply are linked to each other, then because of behind its coil electricity in the less magnetic gap in ironcore choke 1b two ends current flux opposite with permanent magnetic flow direction, current flux is identical with permanent magnetic flow direction in the bigger magnetic gap in ironcore choke 1a two ends, tumbler 3a, 3b 4a, 4b around the shaft rotate, their right-hand member will break away from 1b and the left end that is transformed into them and 1a another state of adhesive mutually, and this mechanism is the two seesaw type mechanisms of a twin coil list magnet.As ironcore choke 1a in Figure 16 and Figure 17 mechanism and 1b are locked and " closing " locking wire circle as " opening " respectively, the then also available unipolarity power supply shown in Figure 11 power supply of the mechanism of Figure 16 and Figure 17.In Figure 16,17 the mechanism two tumblers are arranged all, every tumbler can drive a locking bolt, so Figure 16,17 mechanism are applicable to the double-lock bolt electric lock.Magnet 2 in Figure 16,17 mechanisms and ironcore choke 1a, 1b also can be respectively with an ironcore choke and two magnet displacements, constitute the two seesaw type mechanisms of two magnet unicoil double pendulum type mechanisms or two magnet unicoil, these two kinds of mechanisms do not draw in the accompanying drawings, the analytical method of these two kinds of mechanisms and the course of work and Figure 16,17 similar.
For twin coil list magnet mono-pendulum type mechanism shown in Figure 13, the magnet 2 that is fixed in the middle branch of its parallel circuits on the iron yoke can be replaced mutually with tumbler 3, constitute twin coil moving-magnetic type electromagnetic drive mechanism shown in Figure 180, iron yoke 7e among Figure 18 also can save, and rotating shaft 4 just directly is fixed between iron yoke 7a and the 7b.For shown in Figure 15 two magnet unicoil mono-pendulum type mechanism, the ironcore choke 4 that is fixed in the middle branch of its parallel circuits on the iron yoke can be replaced mutually with tumbler 3, constitutes two magnet moving-coil type electromagnetic drive mechanisms shown in Figure 19.The analytical method of Figure 18,19 mechanisms and the course of work and Figure 13,15 similar.
The embodiment of accompanying drawing 20-23 is a bridge-type magnetic circuit mechanism.Magnetic circuit element ironcore choke 1 wherein, magnet 2, tumbler 3, iron yoke 7 grades have constituted bridge-type magnetic circuit mechanism.In bridge-type magnetic circuit mechanism, all magnetic circuit elements are that bridge-type connects, and its tumbler 3 is on a diagonal of bridge-type magnetic circuit.Figure 20 is that its magnetic circuit is exemplary embodiments of electric lock pulsed electromagnetic drive mechanism of bridge-type magnetic circuit, and in Figure 20, the two ends of magnet 2 are fixed with iron yoke 7a, the 7b that is made by soft magnetic materials such as soft irons, are fixed with ironcore choke 1c, 1d on the 7a.Be fixed with ironcore choke 1a on the 7b, 1b, 1a, 1b, 1c, there is a tumbler 3 that can rotate at the magnetic gap middle part of 1d in rotating shaft 4, tumbler 3 can be made by soft magnetic materials such as soft irons, this is a kind of four coil list magnet list seesaw type mechanisms, in addition, locking bolt 5 is directly to be fixed on the tumbler 3, locking bolt 5 reaches outside the lock housing 6 in Figure 20, this moment, lock was to be in lock " to close " state (being " B " attitude among Fig. 1), permanent magnetic magnetic flux passes 1a and 3 simultaneously, 1c and 3 less magnetic gaps and 1b and 3,1d and 3 bigger magnetic gaps (seeing Figure 20), its magnetic force is with the left end of 1a and 3,1c and 3 right-hand member are pulled together, and make mechanism be in the magnetic self-locking state.When mechanism and Fig. 7,8 power supply circuits link, and when passing to the current impulse I of direction as shown for coil 1, its current flux φ m
