Description

The integrated non-contact type motor turning compound Der Blink und Abblendschalter of reporting to the police

The Der Blink und Abblendschalter of light Presentation Function when the utility model belongs to the control vehicle turning.

The no mechanical contact of the utility model utilization output form is controlled Der Blink und Abblendschalter, and electromagnetic form is adopted in sampling simultaneously, has stopped the intensification situation.Now tradition all adopts relay contact output form and sampling to adopt the resistance form both at home and abroad, this unavoidably causes the mechanical contact life-span short, the disadvantage that the resistance intensification is high, although reach the product that occurs utilization integrated component and electromagnetism sampling on the relevant magazine in the market, can't effectively realize not having the Der Blink und Abblendschalter of mechanical contact output form.

The purpose of this utility model provides a kind of integrated non-contact type motor turning compound Der Blink und Abblendschalter of reporting to the police, adopt integrated component and special power level and level translation technology to form a kind of contact pointless form and can export big electric current, and effective control apparatus device that consumable is little, temperature rise is low.

The report to the police inventive principle of compound Der Blink und Abblendschalter of integrated non-contact type motor turning is: based on monolithic integrated circuit (1/2IC1,1/2IC2), realize that frequency variation signal takes place, the level translation buffering is amplified, power output and relevant discrete component constitute multiplication of voltage and load short circuits protection and overvoltage protection system jointly.Be achieved in that specifically that technically the frequency variation signal producer 1A output that is made of 1/2IC1, C1, R1, R2, R3, R4, R5, L1 ' is through R7 be electrically connected with 1/2IC2 input end among the level translation buffer amplifier 2A that is made up of 1/2IC2, R8, R9, R10, C2, C3, D1, D3 (after dated being of nothing be electrically connected), be connected with BG input end among the power output 3A through 1/2IC2 mouth and R10, it is bright or go out to promote the load Der Blink und Abblendschalter by BG output again; The load short circuits that is made of SR, L2, L2 ', R11, R13, R15, D5 is protected 4A on the other hand, and the 4A action quits work circuit when load short circuits; And the overcurrent protection 5A that is made of R12, D2 absorbs it to the instant high-voltage that occurs in the circuit.

Maximum differential that the utility model is compared with existing like product and advantage are to adopt contact pointless output to overcome mechanical contact and produce the shortcoming that electro spark causes contact burning candle, life-span weak point, fully can be as the regeneration product of a new level.

The utility model relates to 3 width of cloth instruction diagrams altogether, wherein:

The integrated non-contact type motor turning of Fig. 1 compound Der Blink und Abblendschalter scheme drawing structure in kind of reporting to the police, wherein X is the printed circuit board (PCB) of soldering of electronic components, Y is insulation (plastics) shell, Z is for drawing three copper sheets conduction mouths from the printed circuit board (PCB) respectively, as anodal, negative pole () and power output pin.

The integrated non-contact type motor turning of Fig. 2 compound Der Blink und Abblendschalter functional-block diagram of reporting to the police, wherein the frequency variation signal producer is that 1A, the transferring buffered amplifier of level are that 2A, power output stage are that 3A, load short circuits protection are that 5A, L are a plurality of flash light loads totally 6 parts for 4A, overvoltage protection.Be electrically connected according to the order illustrated structure, form this Der Blink und Abblendschalter system.

Fig. 3 is the integrated non-contact type motor turning compound Der Blink und Abblendschalter electronic-circuit diagram of reporting to the police, now combine and be illustrated: by 1/2IC1 with Fig. 2, C1, R1, R2, R3, R4, R5, the frequency variation signal producer 1A of L1 ' formation, R1 wherein, R2, R4, a L1 ' end is connected jointly with the 1/2IC1 input end, another termination of R1 M point, R2 other end ground connection, R3 one end is connected with L1 ' other end, the R3 other end and the R4 other end, R5, R6, R7, C2 negative pole one end and 1/2IC1 mouth link jointly, C1 is anodal to be connected with the 1/2/IC1 input other end with the R5 other end, constitute a RC oscillator, its signal is exported with the R7 other end and by R8 by the 1/2IC1 mouth, R9, R10, C2, C3, D1, D3, the 1/2IC2 input end of the level translation buffer amplifier 2A that 1/2IC2 forms connects and imports, and be amplified to output and obtain the former oscillation frequency signal that a voltage is exaggerated, R8 wherein, R9 sets resistance for the input dividing potential drop, R8, R9 is connected with the 1/2IC2 input end, the R8 other end links to each other with the M point, the R9 other end with connect, C2, C3, D1, D3 forms voltage double circuit, D1 negative pole and D3 positive pole, C2 is anodal to be connected, D1 is anodal to be connected with the M point, positive level of D3 negative pole and C3 and R10 join, the R10 other end and 1/2IC2 mouth with by D4, BG input end among the power output stage 3A that BG constitutes is connected, make signal export the L Der Blink und Abblendschalter to from the BG mouth, control L produces the lights flicker of corresponding frequencies.Its frequency conversion (flash light damages prompting) principle of work and power is: when a plurality of flash lights are all intact, one fixed current is from the positive source L1 (dry-reed tube coil) that flows through, BG to L is to ground, make the inner conducting of dry-reed tube L1 ' (being the electromagnetism sampled form), make R3 in parallel with R4, resistance value reduces, as C1, R4 charges normal constant, fix the frequency of a regulation, when wherein damage of flash light, total current reduces, and also reduces because L1 goes up electric current, L1 ' inside will be ended, R3 breaks away from state in parallel with R4, and it is big that resistance becomes, and makes C1, R4 charging constant becomes big, it is big that oscillation frequency becomes, the flash light flicker is accelerated, reach the frequency conversion purpose, prompting has flash light to damage; Another road load short circuits protection 4A is made of SR, L2, L2 ', R11, R13, D5, and wherein R13 is connected with D5 is anodal, and the R13 other end is connected with L2 one end, and the D5 negative pole is connected with M point, SR positive pole, and R11 connects with L2 ', another termination of L2 ' SR control end.When circuit is short-circuited, the electric current on the L2 that flows through obviously increases, and is enough to make the inner conducting of dry-reed tube L2 ', make the SR triggering and conducting, the M point voltage is reduced to about 1.3V, (the last voltage drop value of R12) quits work entire circuit, D5 is luminous simultaneously lights, and prompting enters guard mode; R12 and D2 form over voltage 5A, because D2 is a zener diode, and positive level ground connection, negative pole meets R12, and the pulse high-voltage that is higher than rated operational voltage is absorbed.
