Description

Electronic flasher

The utility model belongs to a kind of electronic flasher, especially relates to a kind of electronic flash equipment of power actuated vehicle.

Power actuated vehicle, as automobile, motor bike and trac. as a kind of land transport facility, play crucial effect in people's live and work, and the social demand amount are increasing.Vehicle constantly overtaking other vehicles in the process of moving turned, distress alerting, and vehicle start, by stop, stop all too busy to get away flashing feature of maintenance night.Do not have two kinds but at present commercially available Der Blink und Abblendschalter is outer: a kind of is the electric heating element type, and a kind of is the electronic component type.Electric heating do not have the part type be with heating wire on bimetallic plate, during use, electric current makes its heating by heating wire, bimetallic plate is heated and occurs bending and deformation, contacting, flash light is bright.Because the contact is in parallel with the heating wire loop, so the heating wire non-transformer passes through during the closing of contact, the bimetallic plate retraction of catching a cold, and contact open, blinker cancellation is one-period.The heating wire of this Der Blink und Abblendschalter is by the flash of light filament ground, its flash light all is in parallel, the frequency of its flash of light is decided by the resistance of heating wire and the resistance sum of flash of light filament, therefore the flash rate of this Der Blink und Abblendschalter is subjected to load effect big especially, and flash of light relies on due to the electric heating element heating, load is failure to actuate when low, when circuit and bulb short circuit or load easy burn-out again when excessive, is difficult to adapt to complicated driving road-condition.But because it is easy to process, price is low, now still has the part dilly to use.

Another kind of electronic component Der Blink und Abblendschalter is active in one's movements, but also has following defective: the one, and required electronic component is many, complex structure, maintenance is inconvenient.The 2nd, safety method is incomplete, particularly exports careless bonding, and wire fuse does not fuse, and element damages, and the general user does not possess the maintenance level again, can only scrap.The 3rd, load-carrying capacity is also poor, and especially when stopping maintenance in the vehicle way night, the time can not be lasting, otherwise the circuit working mal.The 4th, the electric current that the current limliting sample resistance flows through is big, easily causes the premature aging of other electronic components and loses efficacy.

Of the present utility model open, all can reliable operation when just providing a kind of vehicle and at any time needing to glisten and be not afraid of output because of the cause the failure electronic flasher of element of short circuit.

The technical scheme that the utility model electronic flasher solves is: electronic flasher comprises the control loop of amplifying circuit, amplifying circuit and control circuit, guarantor's despreading circuit.The main body of amplifying circuit is an aerotron, the main body of the control loop of amplifying circuit is a silicon control, the reliable conducting of aerotron with by by the control of silicon control and stabilivolt, silicon control is between the off period, circuit charges to electric capacity by charging resistance, and when charging to stabilivolt voltage stabilizing value when adding PN junction voltage, stabilivolt punctures, the silicon control conducting, this moment, dynamic resistance became very little.Electric capacity instead by the discharging resistance discharge, is discharged to silicon control conducting-state voltage and PN junction voltage sum, so the flash rate of utility model is stable especially.Control circuit is controlled by relay, protects despreading circuit and is constituted by a diode.

A kind of electronic flasher includes the control loop of box body, amplifying circuit, amplifying circuit and control circuit, protective circuit, it is characterized in that: polarity protection diode D ₁Be serially connected in relay J open contact J ₁In the loop after the power supply, the relay J of the e utmost point connection control circuit of aerotron BG, the J coil is also succeeded stream diode D ₂, open contact J ₁Connect output pin L, the c utmost point power connection negative pole of aerotron BG, power cathode protection diode D ₃Be attempted by the two ends of the c utmost point and the e utmost point of aerotron BG, connect the e utmost point of aerotron BG towards the positive pole of capacitor C, negative pole connects towards resistance R ₁With discharging resistance R ₂, towards resistance R ₁Another termination clamping diode D ₄Positive pole one end, diode D ₄Negative pole meet output pin L, discharging resistance R ₂The negative electrode of another termination controllable silicon SCR, the utmost point of the anode of controllable silicon SCR and aerotron BGb joins, stabilivolt wz is attempted by the two ends of controllable silicon SCR.

Accompanying drawing is the utility model electronic flasher basic circuit and practical application connection line figure, wherein:

Fig. 1 is the utility model electronic flasher basic circuit;

Fig. 2 is that connection diagram is installed by the utility model electronic flasher and vehicle operating mechanism, wherein:

--electronic flasher II--pole changer III--is met alert switch to I.

In conjunction with Fig. 1, the utility model is further described.

In circuit shown in Figure 1, pin B meets positive source, flash lamp insurance CD, and output pin L switches through to lamp switch and distress alerting switch, and pin E connects power cathode, polarity protection diode D₁Be serially connected in relay J normally opened contact J₁In the loop after the power supply, the relay J of the e utmost point connection control circuit of triode BG, the J coil also is connected to the stream diode D that continues₂, absorb the magnetic strength electromotive force, normally opened contact J₁Connect output pin L, the c utmost point of triode BG connects power cathode, power cathode protection diode D₃Be attempted by the two ends of the c utmost point and the e utmost point of triode BG, the positive pole that rushes capacitor C connects the e utmost point of triode BG, and negative pole connects and rushes resistance R₁With discharge resistance R₂, rush resistance R₁Another termination clamp diode D₄Positive pole one end, diode D₄Negative pole one termination output pin L, discharge resistance R₂The negative electrode of another termination controllable silicon SCR, The b utmost point of the anode of controllable silicon SCR and triode BG joins, and voltage-stabiliser tube wz is attempted by controllable silicon SCR Two ends.

Embodiment with reference to accompanying drawing, is welded on the element in the circuit on the circuit card, and is fixed in the box body, the lead-in wire switch on, and pin B, L, E be B, L, the E hole of corresponding insertion socket respectively.

The operating voltage of the utility model electronic flasher can design according to the power supply situation of different automobile types, the operating voltage general range is at 6-40v, the difference of the electronic flasher of different voltages is the selection of electronic devices and components, and the great advantage of the utility model electronic flasher is can not take place because the electro-motive force that the output circuit short circuit causes punctures the phenomenon of aerotron BG.
