Description

Anti-theft alarm for motorcycle

The utility model relates to a kind of electronic anti-theft alarm technique, refers to a kind of motorcycle anti-theft alarm especially.

Go up the motorcycle anti-theft alarm of issue with the patent newspaper in the market, adopt cipher control mostly, vibration sensor, dry-reed tubes etc. can play the anti-theft alarm effect, but complicated operation is perhaps unreliable, is destroyed by the thief easily, has certain shortcoming.

Goal of the invention of the present utility model, provide a kind of simple to operate, sensitive failure-free burglar alarm.

Below in conjunction with description of drawings concrete structure of the present utility model.

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

Fig. 2 is ... schematic diagram

Fig. 3 ... the rocker switch structural representation

See also Fig. 1 .2.3.4.5., realize that the technical solution of the utility model is: comprise dc source, detection circuit, warning circuit, emission, receiving circuit, igniting, generator circuit. Key is connected to warning circuit by the detection circuit that vehicle body, rocker switch form, and warning circuit connects radiating circuit; The electric lock switch connects solid switch, and solid switch connects sound circuit, generator circuit. Motorcycle stand footmuff rubber boots.

Described detection circuit I is made the reception and registration device by vehicle body, ic chip (1), electric capacity (C₁), resistance (R₁) form; The detection circuit II is by rocker switch, ic chip (2), electric capacity (C₄C ₅), transistor (V₁), resistance (R₂－R ₄) form; Described warning circuit is by transistor (V₂), resistance (R₅), diode (D₁.D ₂), relay (K₂), ic chip is 3., loudspeaker (Y) forms; Described radiating circuit is by transistor (V₄), inductance (L). Electric capacity (C₇－C ₁₁)/resistance (R₆.R ₇), transmitting antenna forms; Described sound circuit by ic chip 4., buzzer forms, described solid switch is by three-terminal regulator block (WY) and relay (K₁) form; Described receiving circuit is FM receiver, and described firing circuit is by K₂Normal opened contact, an end ground connection, other end contact fire coil forms; Described generator circuit is by K₁Normal opened contact is connected on generator coil and forms.

When using the utility model, motor bike is come to a complete stop first-class lock, direction lock.When closing electric lock, solid switch outage, relay K ₁, normally closed contact (K1-2) is connected annunciator power supply (A), makes alarm work, is on the alert; Normal opened contact (K1-1) disconnects generator coil, motor bike can't be started, with antitheft car.

Touch vehicle body as the people, visit circuit I, trigger warning circuit, vehicle body and owner with receptor send short and little warning simultaneously, tell people to keep off car, tell owner the people to be arranged at bumper car, the actuating of relay in the warning circuit simultaneously, K2 normal opened contact closure with high-tension coil ground connection, prevents to steal car.

As people's picking lock, cut off the electric lock line, car knocked over, ball moves, triggers warning circuit in the rocker switch, vehicle body and receptor send the chimes of doom of sharp-pointed loudness of a sound simultaneously, tell people that the car or the vehicle body overturning of stealing arranged, site disposal immediately, the K2 normal opened contact with high-tension coil ground connection, prevents to start car to run away simultaneously.Automatically stop after two minutes reporting to the police, annunciator recovers the state of alert.

As the people car is moved to when stealing on the automobile, because the ball in the rocker switch ceaselessly rolls, annunciator then successively sends sharp-pointed chimes of doom.Tell passerby that this car goes adrift.

Only open electric lock, connect the solid switch power supply, K1 normally closed contact K1-2 disconnects, and turn-offs annunciator power supply (A), could remove chimes of doom.

During normal the use, the car owner opens the electric lock switch, connect solid switch, the K1-2 normally closed contact disconnects, and turn-offs annunciator power supply (A), while normal opened contact K1-1, connect generator coil, 4. normal opened contact K1-2 connects sound circuit IC, and buzzer sends the signal of circuit on, inform that owner can start garage to walk, thereby reached the purpose of convenient and reliable anti-theft alarm.

Sensitive reliable for guaranteeing annunciator, overlap rubber boots on the motorcycle stand pin, increased the area of contact of fulcrum simultaneously, it is firmly firm that car is parked, not overturning easily.

Use for being fit to various model motor bikes, the utility model can be installed in the various positions of car, as instrument cases, in the vehicle frame side plate, in the magneto generator side plate, in case the thief destroys.
