In a wireless receiving circuit: when a user stops the electric bicycle and needs to set up a defense, after a first wireless transmitting key switch S1 of a portable wireless remote control component finished product A5 is pressed, a wireless remote control component finished product A5 can transmit a first path of wireless closing signal, 4 feet of a wireless receiving component finished product A2 can output a high level after receiving the first path of wireless closing signal, the high level is subjected to voltage reduction and current limiting through a resistor R4 and enters a base electrode of an NPN triode Q5, then the NPN triode Q5 is conducted, a collector electrode of the NPN triode Q5 is conducted to output a low level and enters a negative power input end of a relay J1, and the relay J1 is electrified to attract a control power input end and a normally open contact end of; because the positive power supply input end (the negative electrode of the photoelectric switch A3 is communicated with the 4 pins of the direct-current voltage stabilizing circuit module A1) and one of the terminals of the universal mercury switch SQ of the vibration displacement probe are connected with the normally open contact end of the relay J1, at the moment, the photoelectric switch A3 is in an electrified working defense state, and one of the terminals of the universal mercury switch SQ is in an electrified defense state.

In fig. 2, in the photoelectric switch a 3: when a thief breaks a key power switch of the electric bicycle in the defense, the body and the hand of the thief are close to the front end of a detection head of the photoelectric switch A3, so that under the action of an internal circuit of the photoelectric switch A3, a pin 3 of the photoelectric switch A3 outputs a high level, and the high level is conducted in a single direction through a diode VD3 and enters the other end of a resistor R of the photoelectric module circuit. When a thief steals the vehicle to slightly vibrate the vehicle body, the mercury liquid level at the lower part of the shell of the mercury switch submerges two contacts at the upper part of the shell of the mercury switch, so that the anode of a 6V power supply output by a 3-pin output of the direct current voltage stabilizing circuit module A1 can be conducted in a single direction through the normally open contact end of the relay J1, one of the connection ends of the mercury switch S1, the mercury liquid in the mercury switch SQ and the other connection end of the mercury switch SQ through the diode VD2 and enters the other end of the resistor R of the photoelectric module circuit. In the photovoltaic module circuit: when a thief arrives at a vehicle and wants to damage a key power switch and a 3-pin output high level of a photoelectric switch A3, the high level enters the other end of a resistor R of the photoelectric module circuit through one-way conduction of a diode VD3, or the thief steals the vehicle to slightly vibrate the vehicle body, and a 6V power supply enters the other end of the resistor R of the photoelectric module circuit through the other terminal of a mercury switch SQ and the diode VD2 in one-way conduction; the high level will be through resistance R1 step-down current-limiting entering light-emitting diode built-in with optical coupler A, then, the built-in light-emitting diode of optical coupler A gets electricity and sends the light, after the built-in phototriode base illuminated surface of optical coupler A receives the light, the built-in phototriode of optical coupler A saturates and conducts its emitter to output high level and through resistance R3 step-down current-limiting entering NPN triode Q4 base, then, NPN triode Q4 conducts its collector to output low level and enters relay J2 negative pole power input end, relay J2 gets electricity and attracts its control power input end and normally open contact end to close, because, relay J2 control power input end and direct current voltage regulator circuit module A1 pin 3 communicates, relay J2 normally open contact end and timing circuit adjustable resistance RP another end to connect, therefore, at this moment, direct current voltage regulator circuit module A1 pin 3 output 6V power will enter timing circuit adjustable resistance RP another end (diode VD 4 is mainly played a protective role, when the power output by the pins 3 and 4 of the direct current voltage stabilizing circuit module A1 is reversely connected due to various errors, the diode VD1 has the reverse cut-off function, so that the anode power at the cathode of the diode cannot enter the cathode of the built-in light emitting diode of the optocoupler A to cause the damage of the light emitting diode).

As shown in fig. 2, in the timing circuit: when the 6V power output by pin 3 of the dc voltage stabilizing circuit module a1 enters the other end of the adjustable resistor RP of the timing circuit, the 6V power will charge the electrolytic capacitor C1 through the adjustable resistor RP, and when the electrolytic capacitor C1 is not fully charged at the beginning, the voltage at the base of the darlington tube composed of the NPN triodes Q1 and Q2 through the resistor R1 is lower than 0.7V, the NPN triodes Q1 and Q2 are in the cut-off state, and the subsequent short message circuit a4 and the subsequent short message sounder B will not get charged. In practical situation, when a thief wants to break the key power switch for more than 5 seconds (the thief cannot break and open the key power switch within 5 seconds) when arriving at the vehicle, the 3-pin of the photoelectric switch a3 outputs high level, the high level is conducted in one direction through the diode VD3 and enters the other end of the resistor R of the photoelectric module circuit for more than 5 seconds, or the thief steals the vehicle to slightly vibrate the vehicle body (the vibration generated by the thief whether damaging the lock or righting the vehicle is far longer than 5 seconds), the 6V power supply is conducted in one direction through the other terminal of the mercury switch SQ and the diode VD2 to enter the other end of the resistor R of the photoelectric module circuit for more than 5 seconds, because the pull-in time of the relay J2 exceeds 5 seconds, the electrolytic capacitor C1 can be charged for more than 5 seconds, and the electrolytic capacitor C1 can be fully charged after being charged for 5 seconds; at the moment, the voltage which is reduced by the resistor R1 and limited to enter bases of NPN triodes Q1 and Q2 is higher than 0.7V, then a Darlington tube consisting of the NPN triodes Q1 and Q2 is conducted, a collector of the Darlington tube is output at a low level, the voltage is reduced by the resistor R2 and limited to enter a base of a PNP triode Q3, the PNP triode Q3 is conducted, a collector of the PNP triode Q3 is output at a high level, the PNP triode Q is input at a silicon controlled rectifier VS control electrode, then the silicon controlled rectifier VS is triggered and conducted; because the control power supply input end of the relay J is normally connected with the 3-pin of the direct current voltage stabilizing circuit module A1, the normally open contact end of the relay J is connected with the audible device B and the positive power supply input end of the short message module A4, the audible device B can make a loud sound to frighten field thieves, and the short message module A4 is connected with the negative power supply input end GND of the short message module A4 through one of the control signal input ends X, the short message module A4 can automatically send a short message to a host at the moment, so that the content is 'theft someone', the host can arrive at the field at the first time or inform nearby garage managers, pipes, policemen and the like to the field to prevent the theft of the thieves, and the loss of the host is reduced. Under the action of a timing circuit, under the actual condition, only when a thief wants to damage a key power switch for more than 5 seconds when arriving at a vehicle, the high level is output by a pin 3 of a photoelectric switch A3, the high level is conducted in a one-way mode through a diode VD3 and enters the other end of a resistor R of a photoelectric module circuit for more than 5 seconds, or the thief steals the vehicle to slightly vibrate the vehicle body, and a 6V power supply is conducted in a one-way mode through the other terminal of a mercury switch SQ and a diode VD2 and enters the other end of the resistor R of the photoelectric module circuit for more than 5 seconds, a buzzer B and a short message module A4 can alarm and send a short message; thus, if a person accidentally touches the lock of the vehicle for a certain distance for no more than 5 seconds, or temporarily holds the vehicle body for no more than 5 seconds (for example, the driver of the vehicle adjacent to the parking lot is blocked by the alarm vehicle, is inconvenient to move the own vehicle, needs to temporarily move the alarm vehicle for a certain distance, touches the moving hand part and the like before the photoelectric switch carelessly, or temporarily holds the vehicle body for vibration), because the continuous charging time of the 6V power supply to the electrolytic capacitor C1 through the adjustable resistor RP is less than 5 seconds, the NPN triodes Q1 and Q2 and the PNP triode Q3 are not conducted because the electrolytic capacitor C1 is not fully charged, the alarm B and the short message module A4 can not give an alarm and send a short message, and false alarms caused by other vehicles and drivers contacting the vehicles in an careless short time in practical use are prevented. In practical application, if a person accidentally touches the front of a vehicle lock for a certain distance or temporarily holds the vehicle body position to the right for more than 5 seconds, after the alarm B and the short message module A4 give an alarm and send a short message, a vehicle owner arrives at the site and closes the whole circuit through the wireless remote control circuit board. The novel electric bicycle adopts the photoelectric switch A3 and the vibration displacement probe as double detection alarm signals, so that a user can detect the alarm signals through the vibration displacement probe when a thief pushes the electric bicycle in case that the head of the electric bicycle is not locked by the key power switch; and can prevent one part of the photoelectric switch A3 and the vibration displacement probe from being out of order due to various reasons, and can also detect an alarm signal in time through the other intact probe, thereby playing a good anti-theft role. The resistance value of the adjustable resistor RP is 1M; the resistances of the resistors R, R1, R2, R3 and R4 are respectively 400 omega, 470K, 20K, 1K and 20K; the silicon controlled rectifier VS is a plastic-packaged unidirectional silicon controlled rectifier with the model MCR 100-6; relays J, J1, J2 are Brand Songle 6V relays; the model numbers of NPN triodes Q1, Q2, Q4 and Q5 are 9013; the model of the PNP triode Q3 is 9012; the models of the diodes VD1, VD2 and VD3 are 1N 4007; mercury switch SQ is a glass-encased universal mercury switch of the brand SONTEEN/pinewood.
