Abstract

The utility model relates to a contactless electron flasher. The utility model is composed of a timing derailing switch, an electron derailing switch, a protector and a detector. The electron derailing switch is composed of a VMOS switch tube and a capacitor. The magnetic attachment type relay switches of the existing flashers are replaced by the electron derailing switches, which avoids the problem that the alloy contact point produces sparks and the alloy contact point is easy to oxidize and break, hence enhancing flasher performance and service life. The of the utility model has the advantages of simple circuit, easy production, small size, stable and reliable flashing performance. The utility model is provided with a protector to prevent the electron switch tube from damage, and a detector for inspection. The utility model is a novel electron flasher with full functions, and is especially suitable for direction indicator lamps of automobiles and motorcycles to flash.

Description

Contactless electron flasher

The utility model belongs to the electrical equipment of controlling light flash, and particularly suitable uses on the left and right turning indicator doing on automobile, the motor bike.

Have now and be configured in all kinds of automobiles, steering indicating light Der Blink und Abblendschalter on the motor bike, the power supply of use accumulator direct current supply, the contact is all arranged on the structure of Der Blink und Abblendschalter, be that the folding of removing to control the alloy contact of magnetic-type relay with various method (is the disconnected of power supply, logical) realize the flicker of light, frequent folding because of relay and alloy contact thereof, during by powerful electric current, can on alloy contact, produce spark and cause the oxidation of contact, vibration during vehicle ' and the influence of ambient temperature also can cause the damage of contact alloy, the spring copper sheet of beating also can reduce because of the tired consumptive disease elasticity of metal, these all can cause poor contact of contacts and influence Der Blink und Abblendschalter performance and service life, thereby have the shortcoming that is difficult to overcome.

The purpose of this utility model provides a kind of contactless electron Der Blink und Abblendschalter, structurally adopt electronic switch to replace the magnetic relay, adopt regular switching device control electronic switching device, realize that the opening and closing of non-contact type reach the purpose of light flash, it is stable and reliable for performance, thereby overcomes the shortcoming of existing Der Blink und Abblendschalter.

Narrate structure of the present utility model and principle below in conjunction with accompanying drawing

Accompanying drawing is the utility model circuit structure schematic diagram

See accompanying drawing; the utility model includes regular switching device (I); overheat protector (II); electronic switching device (III) and detector (IV) form; regular switching device (I) is by C1; C2; C3; C4; C5; R1; R2 and IC form the circuit of regular switching device; IC is time-base integrated circuit; IC tool 1; 2; 3; 4; 5; 6; 7; 8 wiring point pin; pin 4; 8 are connected with power supply B; pin 5(controls the utmost point) be connected with capacitor C 5 after ground connection; pin 1 ground connection; pin 2(set trigger electrode) and the pin 6(threshold values utmost point) with capacitor C 3; ground connection after C4 connects; meet power supply B, pin 7(discharge electrode behind connecting resistance R1 and the R2 simultaneously) be connected with resistance R 1 and R2, pin 3 is output stage; with the G utmost point that meets switching tube BG after thermocouple automatic switch S2 is connected; capacitor C 1; C2 one termination power, other end ground connection, C1; C2; R2; C5 plays the power filter effect, is determined by R1, R2, C3, C4 switch time, and after dc source was connected, IC was output as high level or low level by repeatedly conversion switch time, and its conversion frequency is 85 ± 5 times/minute; Electronic switching device (III) comprises BG1, BG2 by BG(...) and C6 form the circuit of electronic switching device, BG is V_HOSElectronic switching tube, its G utmost point connect behind the thermocouple automatic switch S2 pin 3(output stage with IC) be connected, the S utmost point meets power supply B, the D utmost point and capacitor C 6 and flash lamp switch S₁Connect, C6 other end ground connection, according to the watt level difference of steering indicating light, can a plurality of (BG1, BG2 ...) the in parallel use, when IC output is high level, BG conducting light is bright, when IC carries to low level, BG is obstructed, and lights, C6 play the effect of steady light brightness; Form overheat protector (II) circuit by R3, R5, S3 and D1, resistance R 5 is connected in parallel to S2, R3 one termination IC pin 3, other end ground connection is played stable protective effect, and D1 is Zener diode, the G utmost point of one termination switch BG, other end ground connection is exempted from breakdown with protection BG pipe, S2 is the thermocouple automatic switch, when temperature rises to 75～80 ℃ just can automatic disconnection, avoid electronic switching tube BG overheated and damage, when temperature is chilled to normal temperature, just automatically engage, D1 is the voltage-stabilizing protection diode; Form detector (IV) circuit by K1, R4, LED, whether can detect regular switching device (I) circuit normal, LED is light emitting diode, connect the G utmost point that K switch 1 connects the BG pipe again behind the one terminating resistor R4, other end ground connection is behind the plugged, press K switch 1 with hand, LED is luminous, represents that then regular switching device (I) is working properly, thereby need not to connect the steering indicating light load and detect; When the utility model uses, connect steering indicating light and connect dc source, regular switching device (I) work, output high level or repeatedly conversion of low level, repeatedly conversion of electronic switching device (III) switching, the light of steering indicating light is 85 ± 5 times/minute constantly flickers by frequency namely, until till steering indicating light closes.

There was not the spark of relay alloy contact in electronic switch when excellent electricity of the present utility model was to glisten; the problem of oxidation, damage; stable and reliable for performance; long service life, circuit is simple, easy to manufacture, volume is little, establishes by overheat protector and can protect electronic switching tube not to be burned; be provided with detector and can make things convenient for maintenance and inspection; that a kind of function is complete, long service life, stable performance The novel electron flasher is particularly suitable for doing the steering indicating light flash of light at automobile, motorcycle and uses reliably.

Base integrated package when IC of the present utility model can select NE555, NE556 etc. for use, BG can select VNOS switching valves such as TP8P08, TP15P10 for use.
