Abstract

The utility model provides an electrical self-control anti-theft electronic lock for the motorcycle or the automobile. The utility model is composed of circuits, such as a cipher code controller, a converter, a comparator, a counter, an executor, a cipher code generator, etc. The utility model is characterized in that the input end of the cipher code controller is connected with a cipher code opening device which is composed of switches K1, K2, and K3. The cipher code opening device is formed by an existing arbitrary electrical switch which is arranged on the motor vehicle and has a good control performance. The cipher code input of the cipher code opening device is respectively input to a cipher code control circuit by that two to eight electrical switches of the motor vehicle use the circulating on-off mode or the irregular on-off operation mode, the actuator is driven to act to lock or relieve an engine.

Description

Electrical self-control anti-theft electronic lock for motorcycle, automobile

The utility model relates to electric anti-thief device, particularly a kind of electricity system autocontrol anti-theft electronic lock that is used on the power actuated vehicle.

From prior art as can be known, the anti-theft column lock that is used for power actuated vehicle all is types such as mechanical type, electric, electronics, wireless remote control type, electromagnetic type.Its advantage can both play antitheft effect, but the problem that exists is: these Car Burglar Alarms all need instrument or devices such as tyre or more ad hoc remote controller of unblanking, key, switch, keyboard.As the patent No. is 91205063.2 disclosed a kind of cipher power actuated vehicle Car Burglar Alarms, it is to be made of three select switches with some gears, in each select switch, an optional retaining is connected mutually with electric switch, parallel series is in the electric power loop of igniting, signal and the fuel-feed system of controlled vehicle, every selected gear of select switch is formed password, has only when each select switch gear of living in conforms to password to start vehicle.This shows, though this Car Burglar Alarm can play anti-theft feature, but because its unlocking tool is ad hoc select switch, in case therefore select switch because of go to pot, damage is out of control, will cause controlled vehicle can not start because of lighting a fire, and vehicle defect not itself, but caused vehicle launch not because of above-mentioned reason, and having caused unnecessary trouble to the user, this is subjective and objectively all can not put up with.

The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of simple in structure, compact, need not ad hoc unlocking tool, only utilize on the power actuated vehicle existing each electric switch just can be as the input tool of password, lock and car are combined together, have motor bike, the automobile electricity system autocontrol anti-theft electronic lock of double safety simultaneously.

Technical solution of the present utility model is as follows: this electronic lock comprises cipher control changer (1), password comparator (2), register (3), actr (4), cipher code generator (5), password change device (6) is common constitutes.Be connected to one at the input end of cipher control changer and drive a yard device by what power actuated vehicle K switch 1, K2, K3 and not selected password input switch (7) were formed, this drives yard device is to be made of the existing electric switch that has good controller performance arbitrarily on the power actuated vehicle.

Cipher control changer described in the utility model (1) is made of IC 1 and IC2, wherein on 14 and 15 pin of IC1 and the signal that cross-over connection is made up of F1, a F2 on the 7th pin of IC2 disappear and tremble, simultaneously at IC1 the 10th pin and open and be connected to a NAND gate Fo between yard device, the lock core of cipher control electronic lock adopts cmos digital formula integrated circuit to constitute, and Password Length can be set by two to ten scopes according to the structure of this circuit.The input of password simultaneously can adopt two to eight self-propelled vehicle electric switches to be input in the cipher control circuit with circulation break-make or fitfull make-break operation mode.

The utility model is owing to the input tool of the electric switch on the employing vehicle as its password, therefore need not carry any unlocking tool or ad hoc unlocking apparatus also can start vehicle compared with the prior art, this reality is novel to have compact conformation, control convenient and reliable, the code breaking difficulty, good anti-theft effect, cost is low, enforcement is convenient, and the unique two safetys that driving arranged and park cars.

Below in conjunction with accompanying drawing the utility model is illustrated.

Fig. 1 is a circuit block diagram of the present utility model;

Fig. 2 is a circuit structure diagram of the present utility model.

As shown in Figure 1 and Figure 2: this electronic lock is by forming with the lower part, selected password input switch K1, K2, K3, cipher control changer (1), password comparator (2), register (3), actr (4), cipher code generator (5), password change device (6), the common formation of not selected password input switch (7).

Principle of work is: code signal is imported after NAND gate Fo carries out necessary logical process, the coder that is input to ic chip 1 composition of cipher control circuit is encoded, again through ic chip 2 with semaphore lock, sending into the password comparator (2) of F3 to F5 composition compares with the content of the cipher code generator (5) of IC3 composition, conform to as content, then through diode D3 to D5, the OR circuit that resistance R 4 is formed is changed the password change device (6) that signal is input to the IC4 composition to the cipher code generator content, simultaneously register (3) is added " 1 ", the input of wait Next Password is made comparisons again.

Specific embodiment is as follows: establish 9 Password Lengths, select three turnon left light switch K1 on the vehicle for use, right-hand corner light switch K2, main furnace building light switch K3 is input to locking or the releasing of the electronic lock of foregoing circuit formation to engine by three switches being made the different regulation of break-make order with password.Existing setting code order is as follows: turnon left light switch K1--right-hand corner light switch K2--main furnace building light switch K3--turnon left light switch K1--right-hand corner light switch K2--main furnace building light switch K3--turnon left light switch K1--right-hand corner light switch K2--main furnace building light switch K3.When unblanking with behind the key operated circuit of the electric switch of former vehicle, stir turnon left light switch K1 break-make after, input cipher control changer (1) is carried out clearly 0.Second password input is to stir right-hand corner light switch K2 break-make, and signal is sent password comparator (2) to and compared with the content that cipher code generator (5) sends after cipher control changer (1) handles accordingly at this moment.If comparative result conforms to, register (3) numeration is " 1 ", and cipher code generator (5) changes content simultaneously, and the input of wait Next Password is made comparisons again.The 3rd password input is to stir main furnace building light switch K3 break-make, signal is after cipher control changer (1) is correspondingly processed, sending password comparator (2) to compares with the content that cipher code generator (5) sends, content conforms to, register (3) numeration is " 2 ", cipher code generator (5) changes content simultaneously, waits for that the input of the 4th password is made comparisons again.So three switches are pressed in circulation, and when the content of register (3) was " 8 ", the locking to engine was removed in the action of the relay contact of actr (4).

When the input password of as prescribed order not or wrong by when not being selected as the switch (7) of password input, the content of then sending into signal content and cipher code generator (5) is not inconsistent, password comparator (2) will send the signal that register (3) is carried out clearly " 0 ", the destruction program of unblanking, actr (4) is failure to actuate, can not remove locking, thereby reach theft-proof purpose engine.

Shut only need turn off electric switch can the related electronic lock of turning off.
