Due to introducing an electronic switch, the electronic flashing device actually and easily substitutes the traditional flashing device controlled by a thermal relay. Compared with the thermal relay type flashing device, the electronic flashing device has the advantages that the power of the device has large adapting range, a flashing lamp is transformed between 10-80 watts, the device has stable and adjustable flashing frequency, long service life, convenient maintenance, no large heating element, etc. The utility model is not additionally provided with new components on the operation and use and keeps the original using habits of the drivers, having strong applicability, simple structure, mature technique, low requirement for producing equipment, small investment, easy manufacture and convenient debugging, in particular being suitable for reconstructing and replacing the original flashing device controlled by the thermal relay.
Description
The utility model relates to a kind of improved automobile-used Cornering Lamp electronic flasher.
The Cornering Lamp Der Blink und Abblendschalter of domestic and imported automotive use mainly adopts the Der Blink und Abblendschalter of thermal relay control at present.The characteristics of this Der Blink und Abblendschalter are that thermal resistance wire and bulb are in series, and utilizing on the thermal resistance wire generates heat to expanding by electric current makes the closing of contact, thereby the electric current on the thermal resistance wire is cut off in the energising of relay line bag simultaneously, and the electric current that flows through bulb this moment reaches maximum, and bulb is shinny.Thermal resistance wire cooling shrinkage, contact are opened, and disconnect the electric current that the relay line is wrapped, and the electric current that flows through bulb this moment is owing to the access of thermal resistance wire drops to minimum, and bulb is not shinny.The said process reciprocation cycle, thus reach the purpose of flash of light.Because the size of blinker bulb power is directly relevant with the thermal resistance wire heating, therefore the power of bulb has been done qualification, can not arbitrarily change and short circuit, otherwise will burn thermal resistance wire.If bulb power changes about rating horsepower (43W),, will not glisten when serious though do not burn out the change that thermal resistance wire also will cause flash rate.Because flash rate is subjected to bulb power and ambient temperature effect and itself lacks setting device, can't proofread and correct, use maintenance very inconvenient.Recently Bao and also delivered many electronic flasher circuit on the Kan Za Chi, but lack practicality, on market, do not sell.Through preliminary search, find Eltec lecture book series (four) " transistor switching circuit " and published the automobile turning flashing light indicator, the astable circuit that this Der Blink und Abblendschalter is made up of transistor produces oscillation frequency, controls the break-make of bulb by intermediate relay, reaches the purpose of bulb flash of light.This Der Blink und Abblendschalter is very inconvenient in actual applications, particularly the transformation of the Der Blink und Abblendschalter of former use thermal relay formula is changed, and it need increase a source switch in addition, where this switch is installed and is made the driver easy to use, and this is very pain in the neck feelings.Also very inconvenient during use, the driver will successively stir twice switch, and formality is miscellaneous, disperses energy, is not selling on the market and public use so also see this flashing indicator.In addition, the 2PS intermediate relay price height that it adopts, volume is big, and is inapplicable.
The purpose of this utility model provides the electronic flasher of a practicality, and the transformation of the suitable especially Der Blink und Abblendschalter to former use thermal relay formula is changed, and constantly increases source switch, and the Cornering Lamp switch is still with original on the car.Other parts are kept the few as far as possible change of former state.It is simple and convenient transform like this, and applicability is strong, and driver's use habit does not change yet.
The utility model is achieved in that when the turning K switch is removed to the left side or the right, electronic switch (4) conducting, and positive supply is given oscillator (1) power supply by electronic switch (4).Crystal triode (5) promotes relay adhesive reliably with further amplification of flash rate that oscillator (1) produces.This moment relay normally open contact (3) closure, positive voltage is through relay normally open contact (3), the turning K switch directly is added on the turning bulb, bulb is shinny.When not adhesive of relay, relay normally open contact (3) disconnects, and the bulb of turning this moment does not work.The flash rate control that the break-make of relay is produced by oscillator (1).When turning finishes, when the turning K switch placed neutral gear, electronic switch (4) was in off-state, and power supply is not given oscillator (1) power supply.
The utility model can also be: when the turning K switch is removed to the left side or the right, positive supply is by diode (6), chemical capacitor (8), diode (7), turning K switch, turning bulb constitute the loop with ground, this moment, power supply was given chemical capacitor (8) charging, its voltage direction A end is for just, and D point is to bear.After voltage reaches certain value, crystal triode (10) conducting, the C of power supply by electronic switch (4) holds to oscillator (1) and powers.Crystal triode (5) promotes relay line bag (2) adhesive reliably with further amplification of flash rate that oscillator (1) produces.When the relay adhesive, relay normally open contact (3) closure, this moment, positive supply directly was added on the turning bulb by relay normally open contact (3), turning K switch, and the turning bulb is shinny.Because the delayed-action of chemical capacitor (8), positive supply is still powered to oscillator by diode (6) and electronic switch (4).When not adhesive of relay, relay normally open contact (3) disconnects, and the bulb of turning this moment does not work, and power supply charges once more to chemical capacitor (8) again, and electronic switch this moment (4) still is in conducting state.When the turning K switch placed neutral gear, chemical capacitor (8) constituted discharge loop with the emitter-base diode and the resistance (9) of crystal triode (10), and electronic switch (4) is in off-state very soon, oscillator (1) failure of oscillation.
The utility model can also be: the oscillator in the circuit (1) is made of the transistor astable circuit.This circuit produces approximate rectangular ripple, and the protection with the contact is put in the suction that helps relay.
The utility model is compared with the Der Blink und Abblendschalter of thermal relay control commonly used at present, and following advantage is arranged: it is big to have an adaptable power range, and blinker bulb can be selected for use arbitrarily between 10～80 watts, flash rate is stablized adjustable, does not have big heat element, long service life, reliable operation, adjusting is convenient.In addition, thermal relay formula Der Blink und Abblendschalter large scale production quality is wayward, the technological requirement height.And the many switches of the automobile turning flash light that " transistor switching circuit " publishes are changed the transformation difficulty to thermal relay, and the driver uses also inconvenient, the ZPS intermediate relay cost height that it is selected, and volume is big, so inapplicable.The utility model is practical, and production facilities is simple, and investment is little, and debugging is easy, and commune and brigade run enterprise and little factory produce and can make the high slightly this point of its cost obtain solving satisfactoryly.
The utility model has following scheme drawing:
Fig. 1 is the utility model schematic diagram: (1) is that oscillator, (2) are electronic switch for relay line bag, (3) for relay normally open contact, (4); (5) for promoting the aerotron of the reliable adhesive of relay, (6) are for preventing the protection diode of power supply reversal connection.A, B, C are three exits of electronic switch (4).K is original turning switch on the car.
