Abstract
The utility model discloses a theft-proof warning device for a motorcycle, which relates to a signal device which prevents the motorcycle from being stolen. The theft-proof warning device for a motorcycle comprises a main machine which is installed on the motorcycle and an auxiliary machine which is carried about. The main machine comprises a high frequency vibrator and a control switch. The auxiliary machine comprises a superregeneration receiver, a rectifying filter circuit, a non-contact electric switch and an audio frequency multivibrator. When someone steals the motorcycle, the main machine stops transmitting singles, and the audio frequency multivibrator in the auxiliary machine sends sounds out to notify an owner that someone touches the motorcycle. Thus, the utility model can effectively prevent the motorcycle from being stolen.
Description
The anti-alert device of motorcycle anti-theft relates to the signalling apparatus that prevents that motor bike is stolen.
Motor bike has captured market with light, flexible, fast speed characteristics that it was had, enter huge numbers of families, but the lockset that is used for motor bike, mainly contain cable-type padlock, handcuffs chain lock, V shape lock etc., the weak point of above-mentioned lockset is that safety factor is low, as long as the robber is not installed on the motor bike owing to be exclusively used in the burglar alarm of motor bike disconnected once cutting with pressure clamp, thereby causes the continuous generation of the stolen case of motor bike.
The purpose of this utility model is a kind of motorcycle anti-theft alarm that prevents that motor bike is stolen of design.
This motorcycle anti-theft alarm comprises the main frame and the machine of paying, main frame comprises that one has the high frequency generator of emitting antenna, serial connection one normally closed switch and automobile-used DC horn in the electric power loop of high frequency generator, a silicon control in parallel between the power positive end of high frequency generator and negative terminal, be connected to a master cock in the silicon controlled control extremely, master cock comprises the metal adapter plate, fasten a metal hammer and be provided with the derby that can contact with the insulation rope on the metal adapter plate with metal hammer, derby connects the anode of high frequency generator power supply, the machine of paying comprises that one has the super-regenerative receiver of receiving wire, the mouth of super-regenerative receiver is connected to current rectifying and wave filtering circuit by coupling capacitance, the mouth of current rectifying and wave filtering circuit is connected to the contact pointless electric switch, the mouth of contact pointless electric switch is connected to the audio frequency multi-vibrator, and the load of audio frequency multi-vibrator is a loud speaker.
When installing and using, main frame is placed in the shelter on the motor bike, and the machine of paying is carried.Be to save components and parts, the high frequency generator power supply of main frame is selected the battery on the motor bike for use, automobile-used direct current (DC) select for use on the motor bike electricity, normally closed switch is the lock switch on the motor bike.
When motor bike was in the state of parking and lock locked, the normally closed switch closure was connected the power supply of high frequency generator, at this moment, because master cock disconnects, silicon control ends, high frequency generator work, by emitting antenna spatial emission signal towards periphery, after the receiving wire of paying machine is received this signal, the super-regenerative receiver no-output, the contact pointless electric switch is connected, make the input end active potential of audio frequency multi-vibrator, the audio frequency multi-vibrator is not worked, and loud speaker does not ring.When the criminal steals car, the heeling condition of motor bike when parking must be become the erectility when advancing, the metal hammer and the derby of master cock become contact condition by disengaged position, the silicon control triggering and conducting, at this moment, on the one hand automobile-used direct current (DC) send the sound, power supply owing to high frequency generator is quit work by short circuit on the other hand, super-regenerative receiver in the machine of paying is exported a noise because of receiving wire can not receive host signal, this noise becomes a direct current level behind the current rectifying and wave filtering circuit rectifying and wave-filtering, the contact pointless electric switch is disconnected, the input end high potential of audio frequency multi-vibrator, the work of audio frequency multi-vibrator, produce a sound signal, loud speaker sends sound equipment, notifies the car owner people to be arranged just at motor-car, therefore can prevent effectively that motor bike is stolen.
Accompanying drawing shows the embodiment of motorcycle anti-theft alarm, wherein Fig. 1 is the circuit structure schematic diagram of main frame, Fig. 2 is the structural representation of master cock when being in disengaged position, and Fig. 3 is the structural representation of master cock when being in contact condition, and Fig. 4 is a circuit structure schematic diagram of paying machine.
In the present embodiment, motorcycle anti-theft alarm comprises the main frame and the machine of paying, main frame comprises that one has the high frequency generator 1 of emitting antenna 2, the oscillation frequency of high frequency generator 1 is 27MHZ, in the electric power loop of high frequency generator 1 serial connection one normally closed switch 3 and automobile-used direct current (DC) 4, a silicon control 5 in parallel between the power positive end of high frequency generator 1 and negative terminal, be connected to a master cock 6 in the control extremely of silicon control 5, master cock 6 comprises metal adapter plate 7, fasten a metal hammer 8 and be provided with the derby 9 that can contact with the insulation rope on the metal adapter plate 7 with metal hammer 8, derby 9 connects the anode of high frequency generator 1 power supply, the machine of paying comprises that one has the super-regenerative receiver 11 of receiving wire 10, the mouth of super-regenerative receiver 11 is connected to current rectifying and wave filtering circuit 12 by coupling capacitance, the mouth of current rectifying and wave filtering circuit 12 is connected to contact pointless electric switch 13, the mouth of contact pointless electric switch (13) is connected to audio frequency multi-vibrator 14, and the load of audio frequency multi-vibrator 14 is a loud speaker 15.
