Description
The utility model relates to the electric horn of motor vehicle field.
At present, what motorcycle, automobile used is type horn since loudspeaker break-make frequency height, the each working current of contact is big at work, contact burns out easily, so the loudspeaker life-span is short.These loudspeaker adopt mechanical switch simultaneously, and the mechanical arm frequency of operation height of switch causes that easily fatigue of materials produces distortion or fracture; The insulation mode that mechanical arm and shell adopt is the offset plate insulation, and offset plate is easily ground away and lost insulating effect, and makes loudspeaker malfunctioning.
The purpose of this utility model provides a kind of motor vehicle contact-less electric horn, its simple in structure, working stability, not fragile, convenient for production, long service life at the above-mentioned deficiency of existing type horn exactly.
The technical solution of the utility model is: the motor vehicle contact-less electric horn, comprise electric horn and signal oscillating generator, and the signal oscillating generator is by integrated circuit (IC), triode BG
1, BG
2, capacitor C and adjustable resistance R form; 3 pin of integrated circuit (IC) meet triode BG
1Base stage, triode BG
1Emitter meet triode BG
2Base stage, BG
2Collector connect an end of the coil of electric horn, 2 pin of integrated circuit (IC) and 6 pin are received an end of capacitor C simultaneously, adjustable resistance R one end links to each other with capacitor C, and its armature contact links to each other with 7 pin of integrated circuit (IC), an end of adjustable resistance, 4 pin of integrated circuit (IC) and 8 pin, triode BG
1Collector and an end of electric horn coil all connect positive source, an end of capacitor C, 1 pin of integrated circuit and triode BG
2Emitter all connect power cathode.Can also 3 pin of integrated circuit (IC) are unsettled, triode BG
1Base stage link to each other with 7 pin of integrated circuit by resistance, between 7 pin of the armature contact of adjustable resistance R and integrated circuit the serial connection diode; Integrated circuit (IC) is time-base integrated circuit or digital integrated circuit.
Advantage of the present utility model is, because of having cancelled the insulating material at contact, mechanical arm and mechanical arm and housing contacts place, uses electronic switch instead, thereby than long 8-10 times of life-span of existing contact electric horn; Owing to adopt electronic original part as control device, the loudspeaker working stability is convenient to maintenance simultaneously, is safeguarded.
Accompanying drawing 1 is circuit theory diagrams of the present utility model.
Embodiment: the integrated circuit (IC) of signal oscillating generator is selected NE555 for use, triode BG
1Select 3DD325, BG for use
2Select 3DD15D or 3DD15E for use, it is 0.022uF that capacitor C is selected ceramic disc capacitor device, electric capacity for use, and R selects the variable resistor of 100K Ω for use, and supply voltage value is 12 volts of direct currents, and electric horn is selected automobile contact electric horn for use, but removes the contact.The line connection of pressing circuit theory diagrams gets final product, can be with the integrated electric horn inside that is contained in of signal oscillating generator.
Principle of work: after the energized, capacitor C is charged through adjustable resistance R, after charging voltage point is charged to and is higher than 2/3Vcc, triode starts in the integrated circuit (IC), when the electric charge on the capacitor C is discharged into the point voltage and is lower than 1/3Vcc, triode is closed in the integrated circuit (IC), and adjustable resistance R repeats said process generation square wave oscillation again to the capacitor C charging; By the 3 pin output square-wave signal of integrated circuit (IC), through triode BG
1Amplify triode BG
2Drive the electric horn coil and produce magnetic field and sounding.
