Description

Multi-functional high-power flash acoustic signal device for automotive vehicles

This device designer utilizes RCL step response principle and transition electric current/sound equipment conversion technique, release novel " self-propelled vehicle multifunctional high-power flash of light news are rung device " (hereinafter to be referred as " device "), it can be widely used on automobile, trac., the motorcycle and other various motor driven vehicles, multiple functions such as realizing turning flash, interrogate that snap shows synchronously, the compound danger warning of acousto-optic, line broken circuit (disconnected lamp) and short circuit sound equipment prison show.This device inserts the brake circuit, cooperates automatic switch, can also make the usefulness of self-actuating brake danger warning.

So far, the turning flash device great majority of domestic motor vehicle are thermal resistance, reliability is very poor, the flash rate instability often is out of order, load-carrying capacity very low (having only tens watts usually), be afraid of vibrations, life-span is low, and chaufeur is difficult to discover to disconnected lamp, broken string, short trouble, easily causes traffic accident.Particularly point out, because the load-carrying capacity of traditional Der Blink und Abblendschalter is too little, can't implement the danger warning function,, wattage many for flash light requires big special-use vehicle and truck conspicuity marking just difficult more.

At present, some adopts electronic flasher external automobile, with danger warning (safety switch) function, but mostly is the supporting special use of this car, can not exchange, and the circuit complexity costs an arm and a leg, and the anti-overload ability that has is relatively poor, and one and damage and be difficult to repair, be not suitable for China's national situation.In recent years, import flash of light integrated circuit (as SR44 etc.) appearred in the home market, because peripheral cell is more, disconnected lamp is discerned by rule of thumb by the faint variation of flashing speed, feels not obvious, and the cost cost is also high, function singleness, performance are not advanced, not seen widespread use.

In recent years, more domestic entity and individual have developed some Der Blink und Abblendschalters and annunciator successively, and the circuit that has is too complicated, very cause to change conventional mode of connection (Hangzhou Sun Ming chief, patent announcement CN2045710U); Combinations such as the conventional dynamic loud-speaker of the employing that has, switch, structure huge complicated (the Zhejiang Lanxi City second vehicular spare parts factory, patent announcement CN2060408U); The extraordinary negative resistance on-off element of the employing that has and a plurality of components and parts are realized single flash function, and economy, stability indicator is on the low side (Changsha dawn electron tube group, patent announcement CN2072924U).

Present domestic all Der Blink und Abblendschalters (comprising the product of producing, developing), power is generally less, does not possess automatic overload protection function, and uncomfortable cooperation danger warning uses, and just more can not use for Oversize vehicle and towed vehicle.

The present utility model people is according to the relevant regulations of international automobile standard and China standard JB2551-84, consider China's self-propelled vehicle present situation, with new method, to having prolonged the thermal resistance flicker method of having used many decades carries out breakthrough change both at home and abroad, with the simplest and the most direct circuitry means (only realizing flash of light) with R, C, three components and parts of L one relay, minimize cost, a tractor serves several purposes, make it to have traditional thermal resistance Der Blink und Abblendschalter incomparable technical performance and economic performance, the purpose and the aim of this device invention that Here it is.

The utility model adopts the R-C-L(relay) the resonant switch flash of light, only realize on its principle that flash rate is stable with three passive devices, by changing resistance sizes frequency is arbitrarily adjusted; Internal pressure drops is very little, and automatic overload protection (anti-short circuit) function is arranged; Load-carrying capacity is strong, 12V type wherein, and maximum allowable power reaches more than 250 watts, is about four times of traditional thermal resistance Der Blink und Abblendschalter; For the 24V type, maximum allowable power is about the octuple of general Der Blink und Abblendschalter up to 480 watts.

This device adopts flash of light method--R, C, the L relay resonance three element flicker method by the up-to-date release of contriver, appliance is few, therefore has very high economic performance index, interchangeability and high conformity, setting range is wide, is applicable to the various load vehicles of different voltages; Wiring is identical with conventional Der Blink und Abblendschalter, can direct substitution.Because bearing power is big, is convenient to various cars (particularly Oversize vehicle and special purpose vehicle) the danger warning flashing feature is installed; Very cause and to drive 20 15W bulbs simultaneously,, send news synchronously with the flash of light process and ring the usefulness of general automobile do propaganda float.

This device utilizes sound diagnostic method, and synchronously prison shows the mode of operation of steering indicating light circuit, and the driver can in time discover easily in running car and broken string, short circuit, disconnected lamp, and disconnected several, which side is fault occur in, and is convenient to timely maintenance, avoids accident.Simultaneously, this device can also ring the height and the sound equipment length of frequency according to news, judges the size of battery tension roughly; As cooperating with the pneumatically operated brake switch, can make the automatic danger warning of the not enough brake of air pressure, avoid the generation of traffic accident accident.

Device mainly is made up of shell, binding post, flash controller, sound equipment identification news Chinese percussion instrument, and principle of work is referring to figure one.R1, W1, C1, C2, J1(comprise inductance coil L and open contact J1-1), RX forms flashing control circuit.When pole changer K1 set, to C1, C2 charging, voltage is along opening (referring to Fig. 2) on the index rule committee rule by R1, W1 for power vd D.Ration the power supply when pressing uN when driving the main relay starting valve on the electric capacity two auspicious voltages, the relay adhesive, J1-1 connects, and power supply is powered to changeing lamp by main current supply circuit protective resistance RX, J1-1, K1, and lamp is bright.Simultaneously, cond C1, C2 are by R1, W1, RX, J1-1, relay coil L discharge, u.Drop to and keep voltage uH when following, relay discharges, and J1-1 disconnects, and steering indicating light extinguishes.Cond C1, C2 begin charging again, repeat above-mentioned working process, go round and begin again, and realize flash function.Draw electric capacity the two poles of the earth, electric capacity voltage waveform on ground, resistance (R1+W1), the steering indicating light in Fig. 2 mode chart respectively.Flash period T=T is bright+and T goes out; Suitably choose R, C value, make T bright/T=30-70%; When K1 disconnected, power circuit was cut off, and flash of light stops, and does not consume.

The sampling link is made up of two linear elements of RX, W2, realizes △ I/ △ U conversion.BG1, BG2, BG3 and related elements thereof are formed sound equipment identification circuit and sound generator.When normal flash of light, the pressure drop on the protective resistance RX is bigger, and to making BG1 saturated, multi-vibrator output 400HZ left and right sides constant-amplitude signal by the B1 impedance match, makes piezoelectric buzzer send the interrupted sound equipment of constant amplitude.When breaking lamp, since RX go up the electric current pass through will be with the change of load well-regulated reducing, suitably the adjustment sound equipment gives and transfers sample potential device W2, the dynamic internal resistance of BG1 is changed, the base current Ib2 of BG2 will have various changes, and the height of oscillation signal frequency, envelope shape also have obvious difference.

Adjusting W1 can change C and discharge and recharge time constant, makes flash rate satisfy 1.5 ± 0.5HZ requirement.

Regulate W2 and can give the operation point of putting BG1, make under variable loads, flash of light and sound equipment state all can satisfy the requirement of table 1.
