Abstract
The utility model relates to a burglar alarm for motorcycles, which comprises a buzzer, a sensor, a time base circuit, and an early alarming switch. The utility model is characterized in that the signal output terminal of the sensor is connected with the input terminal of the time base circuit, i.e., two feet of the time base circuit; the two feet are connected with a power supply through a resistor R2 and the early alarming switch K; feet 6, 7 of the time base circuit are connected with a delay circuit which is composed of a resistor R1 and a capacitor C1, feet 3, 5 are connected with the buzzer, and the foot 5 is also connected with a capacitor C2. Because the alarm is a separate device, the utility model has the advantages that the assembly is simple without using original control lines in a motorcycle; because the utility model utilizes the rational combination of a mercury point connecting type sensor and the time base circuit, the structure of the device is simpler and more reasonable; compared with traditional burglar alarm, the utility model has lower cost.
Description
The utility model relates to a kind of motorcycle anti-theft alarm, belongs to Eltec.
Its type of existing motorcycle anti-theft alarm is shaken control formula, induction type and mercury contact formula, all needs during installation to be connected with the circuit of motor bike itself, certainly will change original control path of former car like this, and installs complicated.
The purpose of this utility model is exactly in order to overcome above-mentioned weak point of the prior art, and a kind of simple, as not employ any circuit in the car when installing motorcycle anti-theft alarm that assembles is provided.
The purpose of this utility model is achieved in that it comprises buzzer phone, sensor, time base circuit, gives alert switch, and the signal output part of sensor is that 2 pin are connected with the input end of time base circuit, and this 2 pin also passes through resistance R
2, give alert K switch and be connected with power supply, 6,7 pin of time base circuit are connected to resistance R
1, capacitor C
1The time delay circuit of forming, 3,5 pin are connected with buzzer phone, and 5 pin also are connected to capacitor C
2
The utility model compared with prior art, because annunciator is an isolated device, its power supply also is that annunciator itself is self-powered, very simple when therefore assembling, do not employ original control path of motor bike, utilize the combination of mercury contact formula sensor and time base circuit, make this apparatus structure advantages of simple more, cost is compared with traditional burglar alarm greatly and is reduced.
The explanation of accompanying drawing drawing:
Fig. 1 is an electrical block diagram of the present utility model.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model embodiment by buzzer phone 1, sensor 2, time base circuit 3, give alert K switch and form, sensor 2 is a mercury contact formula sensor, the input end of its signal output part and time base circuit 3 i.e. 2 pin is connected, this 2 pin also passes through resistance R
2, give alert K switch and power supply U
+Connect, this power supply is the self-powered of annunciator itself, and 6,7 pin of time base circuit 3 are connected to resistance R
1, capacitor C
1The time delay circuit of forming, 3,5 pin are connected with buzzer phone 1, and 5 pin also are connected to capacitor C
2Principle of work of the present utility model is: closure was given alert K switch and is in early warning status when car was parked.When car was not moving, the mercury contact of sensor (2) was an open-circuit condition, and 2 pin of time base circuit (3) are through resistance R
2Be the forward input, this moment, 3 pin no-outputs were reported to the police; When people's motor-car (promptly stolen), the mercury contact closure of sensor (2) inputs to 2 pin of time base circuit (3) to the negative sense power supply by its signal output part, and this moment, 3 pin then had output alarm, through R
1, C
1The control time of fire alarming is delayed time and was then stopped newspaper in 10 seconds automatically, as continuous motor-car, just annunciator is continuously reported to the police, stops the back until car and stops automatically reporting to the police after 10 seconds.
Claims (2)
1, a kind of motorcycle anti-theft alarm comprises buzzer phone (1), sensor (2), time base circuit (3), gives alert K switch, it is characterized in that the signal output part of sensor (2) is that 2 pin are connected with the input end of time base circuit (3), and this 2 pin also passes through resistance R
2, give alert K switch and power supply U
+Connect, 6,7 pin of time base circuit are connected to resistance R
1, capacitor C
1The time delay circuit of forming, 3,5 pin are connected with buzzer phone (1), and 5 pin also are connected to capacitor C
