Description

The multi-function electronic electric horn

The utility model relates to a kind of electric horn device that uses on the various motor vehicles such as automobile, motorcycle, tractor.

At present, employed electric horn is made up of electric and magnetic oscillation and circuit breaker two parts on various motor vehicles.The electric and magnetic oscillation part is made of solenoid, electromagnetic core, armature, diaphragm; The circuit breaker part is made up of switch contact and the quenching resistance and the capacitor that are connected in parallel on the two ends, contact.When pushbutton switch connect heavily, electric current by coil, made electromagnetic core produce magnetic field suction armature through the contact, drive motion of membrane by armature, the contact is also driven to be disconnected, and cuts off the power supply in the coil, the magnetic field of electromagnetic core disappears, and armature is returned by the effect of diaphragm elastic force, and the contact is connected again.Repeat said process, make the diaphragm vibration velocity reach audiorange and send sound.Because contact breaker points is operated in the audio switch state, the speed height; Electric current by the contact is bigger again, and the self-induction electromotive force of coil is very high, and the contact can produce bigger electric arc when cut-offfing, cause burning of contact, electric horn is often broken down and can not work.Though the two ends, contact also are connected to capacitor and resistance, can reduce self induction voltage, have correspondingly also increased working current, are a kind of negative meanses, can not avoid the ablation and the wearing and tearing of contact fully.According to a lot of automobile drivers and Mechanical Help technician reflection, the failure rate height of electric horn, serviceable life is short, cause because of the circuit breaker fault more than 90 percent, and the tonequality dullness of loudspeaker own, function singleness are debugged complex procedures, inefficiency in production and the repair procedures.

The purpose of this utility model is to provide a kind of have news sound, warning, contactless multi-function electronic electric horn for various motor vehicles, it not only can send sound as existing electric horn, and can also when left and right vehicle wheel turns to and move backward, send news and ring, again can be stolen or be subjected to invading and harassing, reporting to the police as alarm when impacting at vehicle; Also have long service life, characteristics that working current is little.

The purpose of this utility model is achieved in that ringing control circuit, alarm control circuit and feedback circuit by electric and magnetic oscillation part, audio electronics on-off circuit, news forms.The electric and magnetic oscillation part is by the secret armature mechanical connection of diaphragm; Solenoid is enclosed within on the electromagnetic core, is electrically connected with the output terminal of audio electronics on-off circuit; The audio electronics on-off circuit constitutes oscillator by integrated circuit and RC, produce the electronic switch output that sound signal to triode is formed, make solenoid flow through pulse current, the electromagnetic core magnetic field that changes, attract armature chatter to drive diaphragm and send sound, adjust the size of loudspeaker volume and the height of tone by semifixed resistor, by the working power of horn switch button control circuit, the control loudspeaker ring or do not ring; News are rung the control circuit part, constitute oscillator by integrated circuit and RC and produce the low-frequency electric pulse signal, its output terminal is connected with the oscillator of audio electronics on-off circuit, the modulation of generation cross (talk), cause sound class that loudspeaker send with in the sound of news Chinese percussion instrument, the working power of circuit is turned to and the pilot lamp power of moveing backward provides by left and right; Alarm control circuit is connected with the voltage controling end of horn switch button circuit and audio frequency oscillator respectively by the output terminal of integrated circuit trigger; Trigger end is connected with the vibration trigger switch that is subjected to slightly shaking just energy conducting; After the alarm gauge tap is opened, when being rocked, connects by the vibration trigger switch, the trigger counter-rotating that is triggered, make audio electronics on-off circuit Homeway.com ring the power connection of control circuit and work, simultaneously, the voltage controling end of audio frequency oscillator is interrogated the pulse voltage of ringing control circuit output and is controlled, and the sound that loudspeaker are sent is similar to the sound of alarm and realizes reporting to the police; Feedback circuit is composed in series in parallel with power supply by the feedback winding with commutation diode, the feedback winding is wound on solenoid, be enclosed within on the electromagnetic core, when solenoid transfers outage to by energising, the electric energy that absorbs the self-induction electromotive force conversion is to the power supply reverse charge, suppress the self induction voltage of solenoid, prevent to puncture electronic switching tube.

Owing to having adopted such scheme, avoided pitting of contact and mechanical wear phenomenon, prolonged the serviceable life of electric horn, reduced working current, realized that loudspeaker, news are rung, alarm multifunction is one altogether, circuit is simple, the installation wiring is easy, reliability is high.
