The specific embodiment

Shown in Fig. 1 a, Fig. 2 a, there are two push switch SA1 to be connected coding chip ACM1330E respectively in the transmitter of this electronic magnetic lock with SA2, resistance R a and light emitting diode TDa form the emission indicator lamp, and connect on the emission decoding chip, and T630A is a radiating circuit.

Shown in Fig. 1 b, Fig. 2 b, integrated package of pressure-stabilizing 7806 provides constant voltage for decoding chip ACM1550D radiating circuit T630B in the acceptor circuit, resistance R E and SB3 knob are formed the study circuit, resistance R A, RB and light emitting diode TDA, TDB form luminous indicating lamp, resistance R C and CA electric capacity are formed oscillator, radiating circuit T630B, they are connected on the decoding chip.Resistance R 1 and R6 are the biasing coupling resistances, and resistance R 2 is a triode TV1 collector bias, is again triode TV2 base biasing resistor.Resistance R 1, R2, R3, R6, triode TV1, TV2, the control circuit that TV4 forms.Resistance R 4, triode TV3 relay K 1, diode TD2 forms No. one executive circuit, and implements magnetic coil L1 is controlled by KM1.Resistance R 5, R7, R8, microswitch KL1, triode thyrister TS1, diode TD1, TD3, relay K 2 is formed another road executive circuit, and implementing the car load power supply by KM2 is the control of drive circuit.

As shown in Figure 3, mechanical lock part is made up of annular lock body 1 and the lock bridge 2 that is installed in the lock body 1, is provided with in the lock body 1 lock bridge 2 is carried out three spacing lock bridge ring 6, is distributed in lock body 1 interior two head ends and centre, can carry out spacingly to lock bridge 2, also can play the allotrylic effect that stops.One end of lock bridge 2 is fixed with spanner 10, and lock bridge 2 is provided with a small embossment 15, fixing return spring 3 between the middle lock bridge ring 6 in this projection 15 and the lock body 1; The electromagnetic induction device that is made of magnet 4 and magnetic coil 14 is fixed on lock body 1 one sides, the dead bolt 7 of mechanical lock is realized flexibly connecting with magnet 4 by the fixed head 8 that is fixed on the magnet 4, see Fig. 4 a, the structure of fixed head 8 is shown in Fig. 4 b, and magnetic coil 14 places in the coil groove that is provided with on the magnet 4; Shown in Fig. 4 c, Fig. 4 d, the other end of dead bolt 7 is provided with the hook-type the tip of the tongue 13, with on the lock bridge 2 in 5 unidirectional cooperations of two lock bridge grooves of establishing between projection 15 and the middle lock bridge ring 6, prevent the slippage of 15 pairs of lock bridges of tongue spare, be provided with the tongue top 12 opposite with the tip of the tongue 13 directions on the dead bolt 7 before the tip of the tongue 13, the relevant position is provided with the tongue apical pore on the magnet 4, and this tongue apical pore can play the limit function to the tongue top, the top in hole is provided with tongue top spring 11, sees Fig. 4 a.

The operating principle of this lock is as follows:

During locking, with pulling moving wrench 10, lock bridge 2 is rotated, when lock bridge groove 5 turned to the tip of the tongue 13 positions, lock tongue body 7 was ejected by tongue top spring 11 and moves down, and the tip of the tongue 13 blocks lock bridge groove 5 rapidly, and lock is represented locking, and return spring 3 is compressed.

When lock will be opened, give magnetic coil 14 energisings, coil 18 produces magnetic field force, and magnet 4 attracts to move on the dead bolt 7, makes dead bolt 7 to magnet 4 lower ends, tongue top spring 11 is in the high compression state, moved in the attraction of magnetic field force by dead bolt 7, make the tip of the tongue 13 break away from lock bridge groove 5 gradually, last because the disengaging of the tip of the tongue 13, lock bridge 2 is got back to initial position and had both been locked unlatching by the 3 rapid springing of return beam spring.

Wherein electronic circuit partly is that the operating principle of electronic lock and magnetic coil 14 is as follows:

What line-internal used is frame hopping remote control reception and transmitter, adopts ACM1330E/1550D coding, decoding.

When pressing certain of SA1 or SA2, encoder can produce a password, is input to data operation and produces a new code signal, passes through D.End output is delivered to the transmitting tube device and is outwards launched.ACM1330E enters electricity-saving state then.Receive the code signal of exporting after the also demodulation at receiver, be input to decoder, in decoding circuit, sign not, after the computing decoding, remove the signal of control circuit by D1 and the output of D2 end.

D1 end output control signal is given transistor base TV1 through resistance R 1, bias voltage, the conducting of TV1 triode is amplified, R2 resistance is the biasing resistor of the colelctor electrode of TV1, the conducting of TV1 triode, and collector voltage descends, the base voltage of TV2 triode descends simultaneously, the conducting of TV2 triode, R3 resistance are the biasing resistors of TV2 triode, and the conducting of TV2 raises collector voltage.It is biasing resistor that collector voltage one tunnel is given the G control utmost point, the R7 of controllable silicon TS1 through resistance R 5, TD1 diode.Controllable silicon TS1 control utmost point G obtains voltage, controllable silicon TS1 conducting, and electric current provides biasing for triode TV5 base stage through resistance R 8.Triode TV5 conducting.Collector current increases, and relay K 1 adhesive is connected KM1 to whole power supply, and K1 is the long long open relay that closes.Another road provides biasing for triode TV3 base stage through resistance R 4, makes triode TV3 conducting, and the conducting of triode TV3 makes relay K 2 adhesives, and KM2 is connected to the car load power supply, and K2 is the long long open relay that closes.。Another road provides biasing for triode TV3 base stage through resistance R 4, makes triode TV3 conducting, and the conducting of triode TV3 makes relay K 2 adhesives, and KM1 connects to magnetic coil power supply unlatching lock body, and KM1 opens wink wink to close relay.

The control signal of D2 end output is given triode TV4 through resistance R 6, and base stage provides bias voltage to make triode TV4 conducting, triode TV4 conducting, and collector voltage descends.Resistance R 7 promptly is that triode TV4 collector bias resistance is again controllable silicon TS1 anode biasing resistor.Because triode TV4 collector voltage descends, and controllable silicon TS1 anode S is further reduced.Controllable silicon is ended, and triode TV5 base stage loses bias voltage, stop conducting, and relay K 2 closures, KM2 stops to car load power supply, i.e. electronic lock locking.

When static, transmitter and receiver are in electricity-saving state, and triode TV1 base stage does not have bias voltage, triode TV1 and ending, and triode TV2 base stage is in high voltage and colelctor electrode is in low-voltage, does not have control signal to export.Make controllable silicon TS1 not have controlled voltage and end, the TV5 triode also is in cut-off state, relay K 2 closures, i.e. and electronic lock locking, same TV3 triode also ends relay K 1 closure.Triode TV4 can not get signal and also is in and ends.

Relay K 1 work, by transmitter control button SA1 decision, pressing SA1 is K1 work, unclamping SA1 is that K1 stops.Relay K 2 work, by transmitter button SA2 decision, pressing SA2 is that K2 stops, unclamping SA2 is K2 work.KL1 is a microswitch.When rotating lock bridge, touch KL1 controllable silicon is ended, the TV5 triode loses base voltage, and relay closes stops KM2, and car load has a power failure.

Diode TD2, TD3 are anti-inverter voltages; TD1 cuts off controllable silicon TS1 control utmost point G voltage to leak; C2 is a delay capacitor; The C1 filter capacitor; TV1, TV2 are a pair of complementary triodes, adopt NPN and positive-negative-positive; TV1, TV3, TV4, TV5 triode D965; TV2 triode C9012; R1, R2, R3, R4, R5, R6, R7, R8 biasing resistor; 7806 three-terminal voltage-stabilizings.
