state 2: as shown in Figure 6, because front wiper arm 12 is the same with the effect of rear wiper arm 11, for convenience of description, wiper arm 11 is carried out principle of specification later here.Wiper arm 11 after the key (not shown) is rotated by lock core 10, rear wiper arm 11 proceeds to the teeth groove in profile of tooth body 6 counterclockwise, rear wiper arm 11 is depressed profile of tooth card 7 after proceeding to the teeth groove in profile of tooth body 6 simultaneously, as the dotted arrow direction in Fig. 6, this sample prescription tongue gusset piece 5 just can slide left when rear wiper arm 11 continues to rotate counterclockwise, until rear wiper arm 11 is rotated the teeth groove of separating tooth body 6, profile of tooth card 7 resets and is clamped on alignment pin 8 under the twisting force of torsion spring 9.So far, side's tongue gusset piece 5 segment distance that slided, because square tongue 4, profile of tooth body 6, profile of tooth card 7 and square tongue gusset piece 5 are integrally formed by connection, after these sample prescription tongue gusset piece 5 slip one segment distances, lock, side's tongue 4 also just stretches out a segment length locking, as shown in Figure 7, this is one of locking process.The process of unblanking is rear wiper arm 11 opposite spins.Tongue tube magnet 28 on the side's of being arranged on tongue gusset piece 5 slides after segment distances with square tongue gusset piece 5 in addition, the state of firm half locking of the side's of being tongue 4 at this time, state as shown in Figure 7.

state 3: under state shown in Fig. 7, when the side's of being tongue 4 just has been locked into the position of half blocking, because tongue tube magnet 28 has left original position, the first magnetic control dry-reed tube switch 26 is due to the magnetic force that has lost tongue tube magnet 28, the first magnetic control dry-reed tube switch 26 becomes disconnection by original conducting, this signal informs single-chip microcomputer 25, after one minute or certified transmitter 31 press the key switch 312 of setting up defences in the wireless receiving scope, the voltage of an about hundreds of millisecond of single-chip microcomputer 25 outputs is to electromagnet 33, electromagnet 33 energisings produce magnetic force, iron core 331 is moved in adhesive, moving iron core 331 is connecting with barrier plate 35 use screw (not shown)s, barrier plate 35 iron core 331 that also sways in synchrony moves, after moving iron core 331 adhesives, barrier plate 35 has also just moved to breach 51 places of square tongue gusset piece 5, the side's of prevention tongue gusset piece 5 slides to the direction of unblanking, even at this moment there is the people all can not unblank opening the lock with the key outdoors, play the effect of locking outdoors, as shown in Figure 8.Due to the magneticaction of permanent magnetic iron 32, barrier plate 35 breach 51 places of the side's of being attached to tongue gusset piece 5 tightly after electromagnet 33 outage, keep the side's of preventioning tongue gusset piece 5 to the direction slip of unblanking, as shown in Figure 8.After completing these actions, after the lower this state of single-chip microcomputer 25 memories, closeall output, make each several part all in resting state, and to save the electric weight of battery, this is half blocking of door lock.In this state, because wireless receiving circuit outage, barrier plate 35 are adsorbed on breach 51 places, so, as unblanked, must first square tongue 4 be locked into to the end in this state, then prevent button 313 or the method that accesses to your password and unblank by the solution of the transmitter 31 authenticated, could unblank smoothly.

state 4: as shown in Figure 9, Fig. 9 is the figure of door lock full cut-off lock status.After side's tongue 4 is locked into the end, on the one hand, movement due to square tongue gusset piece 5, permanent magnetic iron 32 on the side's of being contained in tongue gusset piece 5 is also and then mobile, the absorption affinity of permanent magnetic iron 32 that made barrier plate 35 break away from, barrier plate 35 resets to home position under the elastic force of back-moving spring 34, by limiting plate 36, limits barrier plate 35 in permanent position, this position be can the side's of stopping tongue gusset piece 5 slip, be also that barrier plate 35 can smooth opening at this position side's tongue 4.On the other hand, after square tongue 4 is locked into the end, tongue tube magnet 28 has been offset again a segment distance, and in this position, the magnetic force of tongue tube magnet 28 is just by the second magnetic control dry-reed tube switch 27 conductings, and this signal has reflected to single-chip microcomputer 25.After single-chip microcomputer 25 is received signal, at first to the wireless receiving circuit power supply, wait for and receive the instruction that certified transmitter 31 sends.If in the wireless receiving scope, supress the anti-button 313 of the solution of the transmitter 31 authenticated this time, single-chip microcomputer 25 can be made response, in one minute, can unblank smoothly by enough keys, and after unblanking, as shown in Figure 6, the state of door lock is identical with state 1.As do not unblanked within this minute, reenter after one minute and wait for the reception instruction, door lock is re-set as to the intelligent anti-theft state.When single-chip microcomputer 25 is waited for the reception instruction, if receive the no signal of the transmitter 31 of authentication, 25 of single-chip microcomputers can not be made response, continue to wait for the reception effective instruction, and door lock also keeps the intelligent anti-theft state, as shown in Figure 9.

state 5: door lock is in the full cut-off lock status, and under the intelligent anti-theft state, if single-chip microcomputer 25 is never received effective unlock instruction (never the people prevents button 313 by the solution of the transmitter 31 authenticated), and have the people unblanking with key, when the position shown in square tongue 4 arrival Fig. 8, when the side's of being tongue 4 just has been opened to the position of half blocking, rear wiper arm 11 could be opened next section after also will revolving again and turning around.After side's tongue 4 is opened to the position of half blocking by the full cut-off lock status, movement due to tongue tube magnet 28, make the second magnetic control dry-reed tube switch 27 lose magnetic force and disconnect, this signal informs single-chip microcomputer 25, single-chip microcomputer 25 sends the approximately chimes of doom of 80 decibels by buzzer 37 on the one hand, send the voltage of an about hundreds of millisecond to electromagnet 33 on the other hand at once, after electromagnet 33 energising again the moving iron core 331 of adhesive drive barrier plates 35, make barrier plate 35 be adsorbed on breach 51 places, the side's of prevention tongue gusset piece 5 slides to opening direction.Principle is because the arithmetic speed of single-chip microcomputer 25 is more many soon than people's action, in rear wiper arm 11 is revolved and is turned around during this period of time, barrier plate 35 is by top action breach 51 places of the side's of being adsorbed on tongue gusset piece 5 early, stopping the further unlatching of square tongue 4, the position of the side's of making tongue in half blocking, can not open.Buzzer 37 send chimes of doom during this period of time in, as single-chip microcomputer receives effective unlock instruction (someone supresses the anti-button 313 of solution of the transmitter 31 authenticated), single-chip microcomputer responds at once, close all output, at this moment needed only, and with key, door lock first was locked into to the end in one minute, then unblank to opening direction, just can open smoothly door lock; If single-chip microcomputer is not received effective unlock instruction, after reporting to the police 30 seconds, close chimes of doom under the front topic of switch lock again nobody, door lock continues to keep the intelligent anti-theft state, the state in this time is that the state after the breach 51 of same state 3 barrier plate 35 side's of being adsorbed on tongue gusset pieces 5 is sentenced is identical, and the response that single-chip microcomputer 25 is done too, is also to close all output, each several part is all in resting state, to save battery electric quantity.At this time that is to say that door lock got back to again half blocking, as shown in Figure 8.

wanting transmitter 31 can send instruction to single-chip microcomputer 25, must carry out transmitter 31 authentications.Method is at first square tongue 4 to be locked into to the end, clicks the learn switch 30 of this door lock, then decontrols, and then presses any button in transmitter 31 more than two seconds, completes transmitter 31 authentications, completes the instruction that the transmitter 31 after authentication sends effective.Otherwise, do not complete the instruction ignore that the transmitter 31 of authentication sends.If cancel certified transmitter 31, at first square tongue 4 is locked into to the end, long by learn switch 30, the time, more than 8 seconds, just can be cancelled all certified transmitters 31, the instruction ignore that the transmitter 31 of cancellation authentication sends.

when the people being arranged in indoor generation emergency, need to unblank to go out, but while not opening due to door lock electronic circuit fault or the other reasons side of causing tongue 4, as long as twisting safeguard knob 13, with the key side's of opening tongue 4 rapidly just.Principle is twisting safeguard knob 13, safeguard knob 13 drives safeguard plectrum 15, and safeguard plectrum 15 drives guide strip 14 down slidings, as shown in Figure 8, coupler body 142 in sliding process on guide strip 14 pushes back home position by barrier plate 35, the side's of making tongue 4 use key energy smooth opening.Side's tongue 4 twists safeguard knob 13, reset guide plate 14 after opening round about.The function of safeguard 141 is exactly at indoor back locking function, when twisting safeguard knob 13, makes the safeguard 141 of guide strip 14 reach latch bolt and shakes hands 22 back, to have stopped the unlatching of latch bolt 18, plays the effect of locking indoor.

if the battery electric quantity in wiring board 24 is low to a certain extent, as shown in Figure 4, the red colored lamp of three-color LED indicator lamp 38 will light, and at this moment will by the electric weight of 39 pairs of batteries of charging socket, supply by the charger (not shown).During charging, the blue lamp of three-color LED indicator lamp 38 also can light, until extinguish after the battery electric quantity abundance.

described burglar alarm also has a function of utilizing password unlocking.Cipher-code input method: first with key, square tongue 4 is locked into to extreme position, till then the rotational lock core side of making tongue moves to the position of half blocking to the direction of unblanking, completes a reciprocating action and input exactly numeral 1, it is exactly that the input numeral is several that this action is several times arranged.When the principle side of being tongue 4 is locked into the end, the second magnetic control dry-reed tube switch 27 conductings, then after square tongue 4 is opened to the position of half blocking to opening direction, the second magnetic control dry-reed tube switch 27 disconnects, it is exactly a pulse signal that the second magnetic control dry-reed tube switch 27 becomes disconnection by conducting at every turn, also often complete top action and once will produce the pulsatile once signal, namely the numeral 1, single-chip microcomputer 25 can record these pulses when the password unlocking program.This door lock adopts four passwords, and every, these four passwords are used 2 to 9 these numerals.In the situation that leaves behind the transmitter 31 that authenticated or transmitter 31 faults and can not unblank, will use this function of password unlocking, the default password of input that must be correct in order just can be unblanked.

the method of password unlocking is: first utilize the method for Password Input sequentially to input first password.Because door lock is now in the intelligent anti-theft state, so can send chimes of doom when first password of input, need not comprehend it, as long as input is first password accurately, be that password is several, will operate by above method several times after door lock after will waiting chimes of doom and stopping and could operate again door lock according to prompting, otherwise the password bad of input.First password must be inputted correctly just can enter the password unlocking program, otherwise chimes of doom stops back door lock, keeps the intelligent anti-theft state.When the input first password correct, door lock meeting stop alarm sound, enter the password unlocking program, send a sound minor of " ticking ", second password of prompting input, at this moment the order in 30 seconds that uses the same method is inputted second password, when the sound minor that door lock " ticks " again, the 3rd password of prompting input, in 30 seconds, order is inputted the 3rd password, again " tick " after a sound minor, finally inputted the 4th password in 30 seconds.If the password of input is all correct, door lock will " tick ", the two sound minor promptings of " ticking ", means to unblank successfully, at this moment just can first door lock be at the end with key, then just can successfully unblank.The process of unblanking will complete in one minute, otherwise door lock reenters the intelligent anti-theft state.If the input four passwords at will have one incorrect, the intelligent anti-theft state of door lock can not change, and can not unblank.Password unlocking only has chance continuous ten times, if continuous ten mistakes of password of input, single-chip microcomputer 25 will cut out the password unlocking program, no longer carries out password unlocking, prevents that other people from utilizing the means of examination code to unblank.After closing the password unlocking program, at this time can only be unblanked by the transmitter 31 authenticated, after being unblanked by transmitter 31, door lock can be recaptured again the password unlocking chance of ten times.The modification of password is by the transmitter 31 of authentication, the password of pressing on transmitter 31 was revised key switch more than 3,110 seconds, door lock can send a sound long of " ticking ", first password of prompting input, at this moment decontrol password and revise key switch 311, input first password by above method, the one sound minor prompting of " ticking " was after this just arranged every 30 seconds, to in 30 seconds, input a password after the minor prompting, until four Password Inputs are complete, " ticking ", " ticking " two sound long prompt cipher ends of input.

last this door lock also has a long journey pattern intelligent anti-theft function.So-called long journey pattern is an electricity-saving function in fact.When the long journey plan is arranged, while not opening the door for a long time lock, after locking door lock, that presses the transmitter 31 that authenticated set up defences key switch more than 3,120 seconds, door lock just enters the intelligent anti-theft state of long journey pattern, by single-chip microcomputer 25, is controlling power saving, to save the electric weight of battery.Remove this state, first with key operated door lock, make door lock in alarm condition, at this moment press the anti-button 313 of solution of the transmitter 31 authenticated, can remove this state.
