Referring now to Fig. 3-9, describe the operation of this locking mechanism in greater detail.

What Fig. 3 described is the jam plate that is in the latched position of below.In this position, lug boss 196 bridle joints of the projection piece part 25 of purl 138 and jam plate.Purl 138 is lived in the lug boss 146 of projection piece 25 and 153 constraints of the wall of lock box body 29, and it can not be moved.Purl 138 is fixed on the actuator 28, by means of roughly being in the hole 135 that is assembled to actuator 28 foursquare protruding 126, this actuator 28 successively bridle joint shank of the key.By stoping moving of purl, also just stoped moving of handle effectively, therefore lock can not be opened.

Fig. 6 and 9 has described the jam plate that is in the enable possition, top.In this position, lug boss 146 not with purl 138 bridle joints, therefore, purl 138, actuator 28 and outer handle 11 all can move freely.Moving of outer handle 11 will be extracted latch bolt out.Its complete process is as follows: rotate outer handle 11 and just rotated square boss 126, driver 28 has just been rotated in the rotation of square boss 126, and this has moved lobe plate 27 in vertical direction again.The mobile rack-plate 26 that driven of lobe plate 27.When rack-plate 26 moves up, make pinion 23 rotations, so just rotate main shaft 51 and extracted the latch bolt that bumps spring mechanism 50 out.

By give one or two main solenoid 110 and 111 power supplies make jam plate below and above vertically move between two positions.Whole moving can be finished in 1/10th seconds.This is very significant, and power supply can make battery consumption reduce to minimum because the short time is to solenoid.By screw and carriage 155 main solenoid 110 and 111 is fixed on the lock box body 29, and the location of solenoid 110 and 111 to make jam plate can below latched position and above the enable possition between vertically move.Main solenoid 110 and 111 can be any suitable type, and such as the solenoid of being made by Ledex company, they can produce 3 ounces power in the time of 6 volts.

The operation of main solenoid must be carried out synchronously with the operation of auxiliary solenoid 112.When jam plate was in the latched position of below, the axle 150 of auxiliary solenoid 112 was perpendicular to jam plate and be received within the groove 151 at jam plate top.Axle 150 stops jam plate to move vertically to the top position effectively.Therefore, before jam plate being promoted, must extract axle 150 immediately out by one or two main solenoid 110 and 111.

Fig. 4 has described in the groove 151 that is positioned at jam plate and the axle 150 of the auxiliary solenoid 112 that the prevention jam plate moves up.In this position, auxiliary solenoid 112 does not consume any energy.After excitation, axle 150 is extracted out from groove 151, no longer hinders moving up of jam plate.Shown in this feelings copper-nickel alloy is in riotous profusion.Jam plate moves up under the effect of one or two main solenoid 110 and 111 as shown in Figure 7 then.What Fig. 6 described is that jam plate is in the enable possition of top and the situation of two main solenoid energisings.After jam plate had moved through spring 180, axle 150 extend in the groove 152 by means of spring 180.This situation as shown in Figure 8.In this position, axle 150 is being supported jam plate and is being limited jam plate, and it can not be moved down.Referring now to Fig. 9, because jam plate just is being 150 supports of axle, thus main solenoid 110 and 111 no powers, thus jam plate is maintained the position of top, and the axle 154 of the main solenoid original position that falls back to them.Fig. 9 also shows, enable possition up, and purl 138 can move by the lug boss 146 of projection piece 25.Has rotated in the hole 120 of pinion 23, and this just bumps the latch bolt of spring mechanism 50 with rotating spindle 51 and extraction.After this operation, extension spring 131 pulling actuators and outer handle 11 turn back to their original position.

When expectation during the latched position of jam plate below moving to from the enable possition of top, the synchronization motivationtheory auxiliary solenoid of advocating peace once more.Give one or two main solenoid energising, main solenoid is (side) lifting jam plate on the axle 150 of auxiliary solenoid 112 just.Auxiliary solenoid 112 energisings are so axle 150 is drawn out of.Cut off the power supply of main solenoid, jam plate is just fallen the latched position of below.Then, spring 180 forces the axle 150 of auxiliary solenoid 112 to extend in the groove 151 at jam plate top as previously mentioned.Whole operation is consuming time less than 1 second.

Exist detector (presence sensor) or energizing switch 31 perpendicular to the jam plate location, therefore can drive by jam plate moving between the upper and lower position.The purpose of this microswitch is to determine the state of lock, promptly be pin or open, and this information is sent to electric controller 3.

The built-in function built-up member are similar to said external operation built-up member.The built-in function built-up member comprise and the essentially identical lock box body of peripheral operation built-up member, actuator, lobe plate, rack-plate and pinion and backboard spare.Unique important difference is that portion does not have jam plate or relative solenoid to prevent that actuator from moving within it.The built-in function built-up member are all identical with external operation device from turning handle to the operation of extracting the lock pin built-up member out.

So cell apparatus 40 comprises any suitable battery, but preferably include 3 volts of lithium batteries that three joints are connected in series.Battery pack is fixed to backboard 61, so that give electric controller 3, solenoid 110,111 and 112, and card reader 31 power supplies.

(agent: described the above-mentioned of locking device and other parts DocKet 3915-01) in more detail, this patent is at this reference section as this patent for the U.S. Patent application of " latch mechanism of multifunctional electronic lock " at the autograph of applying on the same day with the name of George Fu Luolaofu.

As shown in figure 11, electric controller 3 comprises microprocessor 200, it comprises an operation sequence and an one or more lock private mark that is used for microprocessor relevant electric erasable type programmable read-only memory (EEPROM) 202(), it comprises one or more lock private marks a random access memory (RAM) (RAM) 203(), and electric drive 204,206 and 208(they drive auxiliary solenoid or brake solenoid pipe 112, main solenoid 110 and main solenoid 111 respectively).As an example, electric drive is the driver of metal-oxide-semiconductor field effect transistor type, and microprocessor 200 and RAM203 can be provided by a microcomputer.Electric controller 3 also comprises the battery voltage detector 215 of the voltage of a monitoring battery 40, for example, battery voltage detector 215 comprises an analog/digital converter, the input of converter is linked the output of battery, and its output is linked microprocessor, and microprocessor is read cell voltage with digital form.Reading circuit 205 in electric controller 3 is linked the output of card reader 31, and it amplifies the output of card reader and converts this output to number format so that read by microprocessor 200.In one embodiment of the invention, battery voltage detector 215 is used for measuring when cell voltage has dropped under the normal running electric controller 3 needed voltages, in an alternative embodiment of the invention that bottom will describe, battery voltage detector 215 plays a part will describe below another.

Come description operation electric controller of the present invention and relevant solenoidal a kind of mode with flow chart 230 in Figure 12, this flow chart comprises a firmware (firmware) or computer program that is contained among the EEPROM202.When the key card was inserted card reader 31, it promptly encouraged a starting switch (not shown), and this has just constituted the first step 232 of block 230.In response, electric controller 3 energising (step 233), and microprocessor 200 is put variable N equal zero (step 234).Then, read the data (step 236) on the key card, microprocessor one or more lock private marks that will comprise in the data on the key card and the one or more lock private marks that are stored among RAM203 or the EEPROM202 compare then, whether comprise the effective private mark (step 238) that is fit to this lock of unlatching to judge this key card.If this key card comprises so effective private mark, then microprocessor 200 encourages electric drives 204, and electric drive 204 drives auxiliary solenoid or brake solenoid pipe 112 again, thereby makes itself and jam plate 22 break away from bridle joints and extract (step 240) out.Then, whether in advance microprocessor 200 judges a sign of set (step 242), and what this sign was represented is that a solenoid in the main solenoid 110 or 111 failed jam plate 22 is risen during former one or many was attempted.Will introduce the setting of this sign below in more detail.

Suppose and do not have the set sign, then microprocessor is transferred excitation main solenoid 110 and 111 central one period scheduled time an of solenoid, be enough to jam plate 22 is lifted to the enable possition (step 246) of its top during this period of time, when making auxiliary solenoid or 112 outages of brake solenoid pipe, microprocessor can also keep jam plate in this position, spring 180 is extended this solenoidal axle 150 in the groove 152, thereby can keep jam plate 22 position (step 248) above it.For example, only need encourage one of main solenoid 110 or 111 and auxiliary solenoid 112 outage came completing steps 246 and 248 in about 0.1 second.After main solenoid is energized 0.1 second, microprocessor 200 is read and is had detector switch 31, whether in fact has been elevated to its enable possition and whether has been maintained (step 250 and 252) by auxiliary solenoid 112 to judge jam plate 22.If successfully finished the lifting of jam plate 22, then open locking device 8, and microprocessor outage (step 264), the user can open door by the handle that turns the handle.But owing to following reason, jam plate 22 may not be raised and maintain the enable possition of its top.Behind long-term use locking device 8, cell voltage may drop to does not have the single main solenoid of enough energy drives 110 or 111, thereby can not get a promotion jam plate 22 necessary power.For example, drop to about 5 volts when cell voltage is having when carrying, single solenoid 110 or 111 just can not have enough energy to promote jam plate 22.Also have, if the user is added to a torque on the door handle, this torque will make purl 138 lean against on the projection piece 25 of jam plate 22, and therefore generation stops jam plate 22 to move upward and can not be the frictional force that main solenoid overcame.

Under any situation that stops jam plate 22 to promote smoothly, microprocessor all forwards step 254 to, and in step 254, microprocessor is waited for a scheduled time earlier, and then attempts promoting jam plate 22.For example, this predetermined time interval is 1-4 second.By this mode of operation, microprocessor makes variable N increase (step 256), and whether decision variable N is less than 4(step 258 then).This just is provided with a restriction to total number of attempt that jam plate before the outage 22 promotes.If variable N is less than 4, then microprocessor turns back to step 240,242,246,248 and 250, attempts once more keeping above it position with a main solenoid 110 or 111 lifting jam plates 22 and with it.This circulation repeats twice possibly again and equals 4 up to variable N, and when variable N equaled 4, microprocessor 200 made flag set (260) not have capability improving jam plate 22 to show single main solenoid 110 or 111 with reference to above-mentioned steps 242.Then, microprocessor 200 outages (262).

If the user extracts his or her card out, and then card is inserted in the card reader 31 again, perhaps other users insert his or her card in the card reader 31, then electric controller 3 will be once more by starting switch energising (step 232 and 233), variable N is reset to zero (step 234) once more, and reads the data (step 236) on this card once more.If the private mark on this key card is (step 238) effectively, then microprocessor forwards step 242 to, in step 242, and the whether set of little processing determination flag.Because sign is set in step 260, so microprocessor forwards step 244 to, microprocessor encourages two main solenoids 110 and 111 so that attempt promoting jam plate simultaneously in step 244.It should be noted that now using two main solenoids 110 and 111 to produce simultaneously almost is the lifting force of twice when given cell voltage can not provide enough electric energy to make a single main solenoid rise jam plate.This is because how much low the cell voltage under two solenoid loads is unlike a cell voltage under the solenoid load is only arranged, and follow regularity

p＝V ²/R，

Wherein, p is the power that offers each main solenoid, and V is the cell voltage under load, and R is the effective resistance of coil in each main solenoid.It is corresponding with the power that each solenoid produces to offer each solenoidal power, so the power of two solenoid generations is the twice of a solenoidal power under a given voltage.

Be not enough to drive under the solenoidal situation at cell voltage, utilize two main solenoids 110 and 111 just to prolong the application life of battery widely.Battery pack drives time that two solenoids 110 and 111 make the voltage that jam plate rises simultaneously and drives single main solenoid 110 and 111 and make the time of the voltage that jam plate rises much longer having to carry to keep down than battery pack having to carry to keep down.As an example, prolonged about 40% the application life of battery.Should also be noted that always to promote jam plate 22 with two main solenoids if when battery pack is new, so, with the power of battery that must consume compare the power of battery that will consume and promote jam plate 22 near twice, so just accelerated battery consumption.

After step 244, microprocessor forwards to auxiliary solenoid or 112 outages of brake solenoid pipe, thereby it is extend in the groove 152 under the effect of spring angular force, keeps jam plate 22 position above it, if jam plate in fact rises.Then, microprocessor 200 is read and is had sense switch 31, judge whether jam plate has successfully risen (step 250 and 252), if do not have, attempt promoting jam plate with two solenoids 110 and 111, according to step 254,258,240,242,244,248 and 250 through trial behind the predetermined time intervals once, twice or three times.After once successful lifting or three unsuccessful trials, microprocessor outage (step 264).

Should also be noted that if a key card with invalidate lock private mark is inserted in the lock, then will write down this fact in step 238, microprocessor is with regard to not de-energisation solenoid (one or two) and jump to the step 264 that microprocessor cuts off the power supply.

In another embodiment of the present invention, microprocessor finished the step 260 of sign is set after, microprocessor jumps to step 240, jumps to step 242 and 244 then, so that immediately by encouraging two main solenoids 110 and 111 to attempt rising jam plate simultaneously.

The present invention also has an embodiment to finish by flow chart 300, and it utilizes electric controller 3 but store different computer programs in EEPROM202.According to flow chart 300, the insertion of key card has encouraged power switch, to electric controller power supply (step 302 and 304), and started reading (step 306) and whether comprising an effectively lock private mark (step 308) of data on the card so that judge this key card.If this key comprises an effectively lock private mark, then microprocessor excitation auxiliary solenoid or brake solenoid pipe 112 are extracted it out from groove 151.Then, microprocessor is read the output of battery voltage detector 215, fills enough voltage and drives a single main solenoid 110 or 111(step 312 so that judge whether battery can provide).If voltage is enough big, then microprocessor encourages main solenoid 110 or 111 one central (steps 316), give auxiliary solenoid or 112 outages (step 318) of brake solenoid pipe then, if therefore in fact raised the then auxiliary solenoid of jam plate 22 will extend in the groove 152.On the other hand, if the cell voltage that microprocessor is read in step 312 is less than the scheduled voltage that can drive a main solenoid, then microprocessor changes two main solenoids 110 of excitation and 111(step 314 over to), give auxiliary solenoid or 112 outages (step 318) of brake solenoid pipe then.In this embodiment of the present invention, whether be raised regardless of jam plate 22 with regard to beginning outage in the step 318 little processing in back.In a modification of flow chart 300, after step 318, can it be repeated according to going to promote the trial of jam plate by the mode of step 254,256 and 258 explanations among Figure 12 to the microprocessor programming.

As previously mentioned, enforcement electrical lock apparatus of the present invention and controller are disclosed.But under the situation that does not depart from the scope of the invention, can also make a series of improvement and replacement.For example, can come place of switches 31 with hall-effect switch.Also have, if desired, can also substitute this solenoid 110,111 and 112 and the locking device of the special construction of electric controller 3 of being equipped with the latch mechanism of other type.

In addition, if desired, can also use dissimilar electro-mechanical devices to replace solenoid 110,111 and 112 and promote jam plate 22.Therefore, the present invention is disclosed by illustrating, but not limited, should decide scope of the present invention with reference to following claim.
