Principle of work of the present utility model is: it is the approximate rectangular pulse wave signal of 1.42Hz ± 0.08Hz that the Der Blink und Abblendschalter oscillating circuit produces frequency, and the grid that is added to field effect transistor Q1 after this signal process R11 current limliting works under the on off state field effect transistor.When 5. output port P connects with load and when having high level to be added to the grid of field effect transistor Q1, input port P big electric current 6. arrives R12 and R13 (its resistance should according to the model adjustment of field effect transistor) sampling circuit in parallel again through the drain-source utmost point of Q1, then through P 5. port output make loaded work piece (being that turn signal lamp is bright), U1 does not produce buzzer tone; When 5. output port P connects with load, when having low level to be added to the grid of field effect transistor Q1, input port P big electric current 6. can not be through the drain-source utmost point of Q1, this moment P 5. port do not have big electric current output, load cisco unity malfunction (being that turn signal lamp does not work), U1 produces buzzer tone.As follows circulation has just realized turn signal lamp flicker deixis.The value that changes R10, C2 can be adjusted flicker frequency and dutycycle.The signal that sampling circuit R12 and R13 two ends produce through D3, D4 half wave rectification after, C3, C0 are again to its filtering, this signal is added to the base stage of T1, when load just often, this signal is very faint, it is inoperative to T1, promptly T1 works in cut-off region; When load during by short circuit, the signal of taking a sample out makes T1 work in saturation conditions, this moment op amp IC1A in-phase input end by the collecting electrode of T1 drop-down be low level, the Der Blink und Abblendschalter oscillating circuit is with regard to output low level, field effect transistor is turned off.Like this, just realized load short circuit protection function.Should select the less NPN crystal triode of magnification factor to T1, C0 the effect here is that high-frequency impulse is carried out filtering.At present the like product that occurs is selected excessively to the magnification factor of T1, causes motor bike oscillation frequency under storage battery dead electricity and the normal situation of load to be subjected to the influence of the faint output of T1 and instability often has the fast phenomenon generation of intermittent frequency; At present do not have high-frequency impulse filter capacitor C0 in the like product that occurs, add that C0 makes the Der Blink und Abblendschalter oscillation frequency can not be subjected to the variation of power supply and becomes sometimes fast and sometimes slow.Frequency changer circuit carries out faint level of the relatively back output of benchmark to sampled signal and is added to oscillating capacitance C2 two ends.When load just often, 7 pin of frequency changer circuit IC1B do not have level output, this moment, the oscillating circuit oscillation frequency was normal.When load obviously reduces, when the Der Blink und Abblendschalter output circuit has output, the 7 pin output low levels of IC1B, this level has slowed down the charging duration of oscillating capacitance C2, thus the time of lengthening Der Blink und Abblendschalter output high level; During Der Blink und Abblendschalter output circuit no-output, 7 pin of frequency changer circuit IC1B output high level, this level has slowed down the discharge time of oscillating capacitance C2, thus the time of lengthening Der Blink und Abblendschalter output low level.Like this, just realized indicating load obviously to reduce the function of (promptly lacking lamp) with obviously slowing down of Der Blink und Abblendschalter flicker frequency.D2, R1, R2, R3, R4 provide a unmodified reference voltage for the inverting input of IC1B.It is the approximate rectangular pulse wave signal of 2.4Hz ± 0.9Hz that the annunciator oscillating circuit produces frequency, and the base stage that is added to crystal triode T3 after this signal process R20 current limliting makes it promote field effect transistor and works under the on off state.Diode D6 and capacitor C 5 constitute the half wave rectification filter circuit provides more stable promotion voltage for T3.21 pairs of T3 collector currents of resistance R carry out current limliting, and the effect of transistor diode D7, D8 is to prevent reverse-conducting.Capacitor C 5 also has the effect of quickening.P 2., 1. P be the annunciator output port, and 3. P is the annunciator grounding ports.Delay control circuit utilizes the RC charge circuit to realize.When 4. power port P was coupled with voltage, voltage charged to C6 through R23, and the current potential at C6 two ends makes the level generation upset from high to low of IC2B7 pin when rising to certain potentials, thereby makes field effect transistor Q2 by pinch off.The effect of capacitor C * is the instant reverse that quickens IC2B 7 pin, has eliminated the conditions of streaking of upset moment.D9, R27, R26 constitute the discharge loop of delay capacitor C6, and this makes annunciator stop to the motor bike point also can flash caution.The value that changes R23, C6 can change delay time.When Der Blink und Abblendschalter is worked, the PNP crystal triode T2 base stage of Der Blink und Abblendschalter control circuit is coupled with the voltage that is lower than emitter 0.7V, T2 is in conducting state, the P 6. power line voltage of port is added on the delay capacitor C6 through T2, D11, R22, because of R22 little more than R23, so with regard to finishing the level that the charging of delay capacitor C6 is made IC2B 7 pin fast from high to low upset takes place in less than an annunciator oscillation period, field effect transistor Q2 is by pinch off, thereby realizes the Der Blink und Abblendschalter priority function.D1, C1 constitute the power supply half wave rectification filter circuit of Der Blink und Abblendschalter part, and D10, C7 constitute the power supply half wave rectification filter circuit of annunciator part.
