Abstract
The invention relates to an automobile horn. The automobile horn comprises a normally-closed contact switch, an iron core, an armature, a membrane, a magnetic coil and a special switch circuit. The switch circuit is connected with the magnetic coil in series, one end of the normally-closed contact switch is connected with the power supply end of the magnetic coil, and the other end is connected with the control end of the switch circuit. Because the normally-closed contact switch is connected with the control end of the switch circuit, the working current is very small, electric arc is avoided when working, and the safety and service life are improved.
Description
Technical field
Automobile component of the present invention, especially relevant with car horn.
Background technology
General, car horn comprises: normally closed contact switch, iron core, armature, diaphragm, magnetic coil etc.Normally closed contact switch wherein and magnetic coil are connected in series.After switching on power, magnetic coil is by normally closed contact switch connection power supply, and under the effect of iron core and armature, normally closed contact switch disconnects; After normally closed contact switch disconnects, coil losing electricity, iron core, armature get back to original position, and normally closed contact switch is switched on power again, and diaphragm produces to-and-fro movement thus, produce sound wave.Its deficiency is normally closed contact switch because be directly coil switch power, and working current is large, easily produces arc spark, containing in gasoline gas environment, easily causes blast or incidents of spontaneous combustion, there is potential safety hazard, also has short point in serviceable life simultaneously.
Summary of the invention
The object of this invention is to provide one safer, the car horn of long service life.
The object of the invention is to reach like this, comprising: normally closed contact switch, iron core, armature, diaphragm, magnetic coil and on-off circuit.Wherein, on-off circuit and magnetic coil are connected in series, normally closed contact switch one termination magnetic coil power end, another termination on-off circuit control end.
Object of the present invention can also be reach further like this: connect stabilivolt and buffer capacitor between the input end of on-off circuit and output terminal, switching circuitry output connects power cathode after connecing commutation diode.
From the above, after driver presses horn switch, loudspeaker switch on power, normally closed contact switch connection power supply, and the control end of on-off circuit obtains high voltage, circuit turn-on, and magnetic coil is energized, and iron core and armature movement, make normally closed contact switch disconnect; After normally closed contact switch disconnects, coil losing electricity, iron core, armature get back to original position, and normally closed contact switch is switched on power again, and diaphragm produces to-and-fro movement thus, produce sound wave.Because normally closed contact switch is connected on on-off circuit control end, working current is very little, thus realizes object of the present invention.
Accompanying drawing explanation
Fig. 1 is the invention process illustration.
Embodiment
See Fig. 1, in the present invention, on-off circuit 3 and magnetic coil 1 are connected in series, termination magnetic coil 1 power end of normally closed contact switch 2, another termination on-off circuit control end 31.On-off circuit 3 also connects breakdown switch circuit 3 when stabilivolt 32 and buffer capacitor 33 can prevent magnetic coil 1 from discharging electric energy, implements protective effect to on-off circuit 3.On-off circuit 3 connects power cathode after connecing commutation diode 34.
On-off circuit 3 can select the switch triode that power is larger, operational amplifier, field effect transistor etc., and through test of many times, select N channel field effect transistor effectiveness comparison good, performance is more stable.
From the above, normally closed contact switch 2 switches on power, and the control end 31 of on-off circuit 3 obtains high voltage, circuit turn-on, and magnetic coil 1 is energized, the iron core of loudspeaker and armature movement, and normally closed contact switch is disconnected; After normally closed contact switch disconnects, coil losing electricity, iron core, armature get back to original position, and normally closed contact switch is switched on power again, and diaphragm produces to-and-fro movement thus, produce sound wave.Because normally closed contact switch 2 is connected on on-off circuit control end 31, its operating circuit is very little, thus avoids generation electric arc when normally closed contact switch 2 works, the safety in utilization of raising, make normally closed contact switch 2 avoid arc damage, the life-span increases greatly simultaneously.
