Description
A kind of vehicle signal generating means is applicable to the power actuated vehicle that adopts 12 volts or 24 volts voltages.
The turning flash device that the current mobility car uses is a relay contact type turning flash device, because be in long-term power supply and oscillatory regime, the high pressure that produces when still bearing vehicle operating when not working is to the impact of element, and it is unreliable to work, and service life is short.
The utility model will design a kind of overload self-protection that has exactly, can the long period bear the not bad long life contact pointless turning flash device of short circuit, compare with relay contact turning flash device, and reliable operation, improve service life greatly.
The utility model is made up of elements such as switch integrated circuit, hunting of frequency source and peripheral resistance, electric capacity, diode, stabilivolts; switch integrated circuit adopts high-power, as to have overload protection thick film integrated component; integrated oscillator circuit can be adopted in the hunting of frequency source, the oscillating circuit that also can adopt independent component to form.Switch integrated circuit input end power connection positive pole, mouth switches through to the switch mid point, and control termination oscillation source mouth is equipped with diode between ground terminal and the mouth, and ground terminal is the joining power negative pole not, and cond is connected between input end and the ground terminal.Dial to left or when right-hand when pole changer, to the capacitor C charging, electric current is through C, diode D, pole changer L, bulb power connection negative pole earlier.C is that switch integrated circuit IC1 and oscillation source IC2 set up an operating voltage, when IC2 output high level, and 3 pin of IC1 and 5 pin conductings, make bulb shinny, 5 pin are high potential, and are basic identical with power line voltage, D ends, and the electric energy that C stores continues to IC1 and IC2 power supply, unlikely outage.When the IC2 output low level, 3 pin and 5 pin of IC1 end, and 5 pin are active potential, the D conducting, C is recharged again, goes round and begins again, and occurs a continual Rectified alternating current on C, to not influence of IC1 work, for guaranteeing the stable of frequency, the power supply of IC2 is supplied with after R, CW voltage stabilizing.When pole changer is allocated to midway location when not working, the back cease operation of having released of the electric energy on the C is no longer born any voltage on each components and parts.
The utility model is simple in structure, owing to adopt high-power contact pointless output, uses reliably, and work life is extremely long.
Accompanying drawing is a structural representation of the present utility model.
Switch integrated circuit IC1 adopts high-power, as to have overload protection thick film integrated component, and integrated oscillator circuit can be adopted in the hunting of frequency source, the oscillating circuit that also can adopt independent component to form.Switch integrated circuit IC1 input end 3 power connection positive poles, mouth 5 switch through the mid point to switch L, and control end 2 connects the IC2 mouth, between ground terminal 1 and the mouth 5 diode D are housed, and cond C is connected between input end 3 and the ground terminal 1.When pole changer L dials to left or when right-hand, to the capacitor C charging, electric current is through C, diode D, pole changer L, bulb power connection negative pole earlier.C is that IC1 and oscillation source (1) are set up an operating voltage, when oscillation source (1) output high level, and 1C1 the 3rd pin and 5 pin conductings, make bulb shinny, 5 pin are high potential, and are basic identical with power line voltage, D ends, and the electric energy that C stores continues to IC1 and oscillation source power supply, unlikely outage.When oscillation source 3 brought out existing low level, IC1 the 3rd pin and 5 pin ended, and 5 pin are active potential, C is recharged again, goes round and begins again, and occurs a continual Rectified alternating current on C, to not influence of IC1 work, for guaranteeing the stable of frequency, the power supply of oscillation source is supplied with after R, CW voltage stabilizing.When pole changer L is allocated to midway location when not working, the back cease operation of having released of the electric energy on the C is not born any voltage on each components and parts.
