Below in conjunction with drawings and Examples the anti-theft lock for motorcycle that foundation the present invention proposes is described further.
The locking bar that the anti-theft lock for motorcycle that proposes according to the present invention includes lock body, snap close and can be inserted and withdraw from snap close by motor-driven.When locking bar inserts snap close, for shutting state; It when locking bar 1 withdraws from snap close unlocking condition.The structure of lock body is referring to Fig. 1, and lock body is made up of swinging block 4 and housing 9 two parts, and can relatively rotate between swinging block and the housing.Motor 10 is positioned at housing, and after motor output was slowed down by gear train, the one tunnel passed to stroke gear 3 and turning gear 2 through driving gear with power, and another Lu Zejing switch cam 8 is stirred electric power switch 7.Fixed frame 11 also is housed on housing, and the front fork of motorcycle passes fixed frame.Referring to Fig. 2,3,4, the contacted side of swinging block and housing is a cavity again, and the cavity center position is a fixed axis 12.Turning gear 2 is fixed on the swinging block by pinning, and stroke gear 3 then is enclosed within on the fixed axis.Be processed with tooth bar on the locking bar 1, and be horizontally through swinging block 4.The stroke gear is meshed with locking bar, and drives locking bar and advance or retreat.Turning gear is fixed on the swinging block 4 by pin 14, and it has toothed portion only to account for 1/3 of circumference to lack, and this has toothed portion only to be meshed with driving gear.Therefore when driving gear 13 only is meshed with the stroke gear, then drives pin rod and advance or retreat; And when driving gear and stroke gear and turning gear all meshed, because turning gear is fixed on the swinging block, so driving gear drove swinging block by turning gear and rotates, and in the swinging block rotation process, the stroke gear then dallies, and locking bar is motionless.For swinging block is matched with housing easily, radially inwardly be extended with part flange 6 on swinging block and the housing contact surface in the present embodiment, opposite position then is processed with the flange 5 that radially outward stretches out as shown in Figure 1 on the housing, and the mutual interlock of two flanges during assembling makes swinging block and housing to sway, then be fixed in the axial direction, certainly, in another embodiment, also can be connected with housing by the fixed axis on the swinging block, as be spirally connected, can reach the effect that axially interfixes equally.
The mutual moving-state of swinging block and housing is referring to Fig. 5, Fig. 6.Suppose the state after swinging block 4 is still in lock, after control circuit received the coded command that remote controller sends out, motor rotated to the direction of setting, and the speed change by gear train finally drives turning gears 2 and 3 rotations of stroke gear by driving gear 13.Because turning gear is fixed on the swinging block, swinging block rotates, and the stroke gear then dallies.When swinging block went to 90 °, driving gear and turning gear broke away from engagement, and detent mechanism is locked to each other swinging block and housing simultaneously.Along with the continuation rotation of motor, driving gear inserts in the snap close by stroke gear drive locking bar 1.Switch cam is one week of stroke just then, and electric power switch is withstood, and cuts off motor power, completely shuts process.
When control circuit receives the remote controller code signal once more, motor with shut the direction rightabout locking bar slowly withdrawed from.When locking bar fell back on certain position, detent mechanism was touched, and made swinging block and housing break away from the state that fixes.Thereby turning gear is meshed with driving gear again and drives swinging block from 90 ° → 0 ° rotation, up to one week of switch cam stroke motor power is cut off.And the process that is meshed with driving gear at turning tooth wheel, the stroke gear then dallies, and locking bar is motionless.
The detent mechanism structure chart is referring to Fig. 7,8,9.Detent mechanism is contained in the swinging block, and it triggers element is first to stir cross bar 15, and executive component is an alignment pin 19.First end of stirring cross bar is embedded in the groove of locking bar 1, and groove then has certain length.First stirs cross bar is enclosed within on the bearing pin, and the other end then is inserted on the slide block 16 that can rotate around the axis.Second stirs cross bar 17 1 ends is contained on the slide block, and the other end is stuck on the executive component alignment pin 19, and its middle part then is enclosed within on the axle.Be with back-moving spring 18 on the alignment pin.When first end of stirring cross bar was positioned at the groove of locking bar, alignment pin stretched out the end of swinging block and inserts in the housing 9, thereby swinging block and housing are completely fixed mutually.And when locking bar 1 moved to certain position, first stirs cross bar slightly skidded off groove, also is that locking bar is stirred first and stirred cross bar, thereby slide block is swayed, and drove second and stirred cross bar and stir alignment pin, made the alignment pin retraction.This moment, swinging block and housing can rotate each other.
Control circuit and remote control circuitry schematic diagram are referring to Figure 10, and remote controller mainly is made up of the coding transmitter unit, and the model of transmitter module IC8 is HS101-12B, and the model of encoder IC12 is VD5026.18 pin of IC12 connect power supply behind press button SS1,17 pin connect 2 pin of IC8 through resistance R 33.When pressing SS1, IC12 gets electric, and its 17 pin output square-wave signal is sent into the IC8 inner modulation through R33, by concealed antenna to spatial emission.Encoder IC12 has seven device attitude address codes, the four figures certificate, and it is encoded up to more than 1.60 ten thousand groups.Remote controller adopts the 12V powered battery, R35, D9 composition work indication.
Control circuit includes to receive deciphers, starts time-delay, automatic reverse and alarm unit.Wherein, decoding unit is exported one the tunnel and is connect the startup delay unit, and another road connects the automatic reverse unit.The core parts of automatic reverse unit are a relay, the rotating of this relay control motor.Stop that reset unit from motor current supply circuit power taking stream signal, triggers the automatic reverse unit.Situation such as can't unblank when preventing that remote controller from losing also is connected to cipher switch in the motor current supply circuit, password is correctly then connected motor power.Control circuit preferably includes alarm unit, and these unit core parts are vibroswitch, when vibroswitch is vibrated, then send chimes of doom by microphone device.Cipher switch preferably joins with alarm unit, alarm unit sounding alarm then when dialing the wrong number password.If in alarm unit, increase the alarm transmitter unit, in remote controller, increase the alarm receiving element, then can realize tele-alarm.
Receive decoding unit by receiver module IC1 (model is HS201-B), decoder IC2 (model is VD5028) forms.After IC1 receives the coding carrier signal, send into IC2 and decipher through modulation, amplification, shaping output square-wave signal.If coding, is deciphered 17 pin of live end IC2 with the set address of IC2, when numeric data code is consistent and is exported high level.This level one tunnel is coupled in the startup delay unit through capacitor C 1, and the automatic reverse unit is sent on another road.
Start in the delay unit, by time-base integrated circuit IC3 (model is LM555), capacitor C 2, resistance R 4 are formed delay circuit, and this circuit is in reset mode at ordinary times, 3 pin output low levels, not conducting of triode V1, relay K 1 is failure to actuate, when 17 pin of decoder IC2 are exported high level when C1 is coupled to 2 pin of IC3, make the upset of IC3 circuit, 3 pin output high level makes triode V1 conducting through current-limiting resistance R6, relay K 1 adhesive.Because the constant open contact of K1 is attempted by on the electric power switch, so electric motor starting and drive switch cam and rotate.When switch cam was left the electric power switch summit, the contact of S1 was connected automatically, and motor also can get through S1.And C2 charges by R4, makes the 6 pin current potentials of IC3 rise, and when current potential during greater than supply voltage 2/3, the circuit upset resets, and 3 pin recover low level, and the K1 dead electricity disconnects, and power supply is powered to motor through S1.
In the automatic reverse unit, form circuits for triggering by triode V2, V3, resistance R 7, R8, R9, R10, IGCT VS1, VS3, triode V4, capacitor C 7, resistance R 16, R12, diode VD3, relay K 2 are formed automatic reversing circuit.When 17 pin of decoder IC2 output high level, make V2 conducting, V3 conducting.Thereby on V3 load resistance R10, form pulse voltage and send into IGCT VS1 gate pole, make the VS1 conducting.After relay K 2 adhesives, its normal battle is closed, causes the motor power commutation, and motor rotates to shutting direction, and drives the switch cam rotation.When motor went to a stroke, switch cam returned back on the electric power switch summit, the stall of motor dead electricity.At this moment, 1 and 3 liang of contacting of S1, power supply triggers IGCT VS3, makes it conducting through resistance R 16, diode VD3.V4 then loses forward bias voltage and ends.The VS1 dead electricity is ended, K2 power interruption recovering original state.When operating SS1 again, 17 pin of IC2 output high level because VS3 keeps conducting, so V4 still ends, makes relay K 2 normally closed somes connections and keeps motor to the direction running of unblanking.VS2 recovers reset condition when total power switch.
Stop in the reset unit that by resistance R 13, R18, R19, triode V5, V6 form voltage detecting circuit, when motor rotation just often, the pressure drop on the R19 is lower, V5, V6 end.Thereby guarantee the V4 conducting, the K2 adhesive of often making war shuts the motor rotation.When locking bar was obstructed, current of electric increased, and the voltage increase on the R19 makes V5, V6 conducting, and V4 is transferred to by conducting and ending, the K2 dead electricity, and its constant close contact is connected, and motor reverses and unblanks, up to replying ortho states.
For the reliability that guarantees to shut, get rid of interference to the stroke later stage, set up a delay circuit, this circuit is made up of resistance R 15, capacitor C 9, triode V7.In a period of time (for example in the 5S), C9 has been recharged and has made V7 conducting VS2 to end when stroke begins to rotate, and V5, V6 also end, and V4 is in conducting state.At stroke later stage (in the 5S of back), as the retaining that is hampered again, because of the VS2 control utmost point is in electronegative potential, V6 dead electricity remain off.No matter detect voltage and whether exist, V4 is unaffected, so got rid of the appearance of stroke later stage homing action, guarantees the reliability that shuts.
The alarm unit core devices is vibroswitch KL, and when housing was subjected to vibrating, KL moment was connected power supply, triode V9, V10 conducting immediately, and capacitor C 12 chargings simultaneously, triode V11 obtains also conducting of forward bias, connects the power supply of warning circuit IC7.The model of IC7 is TM8060A, and its output signal is coupled to V12, V13 through C13 and amplifies promotion audio-frequency transformer T1, by the sounding component sounding alarm.After KL disconnected, C12 still made V9, V10 conducting by a utmost point and the R2 discharge of R16, V9, V10, makes the alarm unit delayed alarm.
Alarm transmitter unit and alarm receiving element circuit and remote-controlled launch unit and decoding receiving element circuit are basic identical:
Under the situation that K3 connects, when vibroswitch KL is subjected to vibrating, the power supply that connects vibroswitch is connected encoder IC11 through R25 moment, IC11 gets electric work, at its 17 pin output square-wave signal, sending into transmitter module IC5 through R22 modulates, and by concealed antenna to the spatial emission signal, after receiver module IC9 receives signal, deliver to 14 pin of decoder IC10 by 2 pin and decipher, when signal that receives and the address that transmits, when numeric data code is consistent, 17 pin of IC10 output high level, integrated 801A of music alarm starts working, and given a warning by 801A promotion piezoelectric patches MTD2.
Cipher switch is made up of the eight-level code switch, is divided into SS1-SS8, sets the 2-6 number arbitrarily as effective code, and surplus position is as the camouflage alarm code.When the chance wireless remote control can't be operated, stir directly starter motor of this sign indicating number, reach the purpose of unblanking by force.
