As shown in Figures 2 and 3, with a plastic casing, work the effect of installing and fixing.The circuit of packing in the shell after the encapsulation, is drawn or is drawn with connector with wire harness.For going up pin, YK252 distributes among Fig. 3, the long 130+ of wire harness/-10mm, the sheath model is DJ7061-6.3-11.
Symbol-,+, L, INT, Wa, P represent ground wire, electrode line (24V), rain shaving electrical machine low speed armature end, wiper switch intermittently shelves, spray switch (scrubber control), reset motor end respectively.
The principle of work (is example just to control) that specifies enforcement below in conjunction with accompanying drawing is; When wiper switch was in scram position, reset motor end P (rain shaving electrical machine reset terminal) connects negative pole, and (rain shaving electrical machine reset terminal ground connection formed lock torque; See Fig. 4); First capacitor C 1 is through first resistance R 1 and the 2 beginning reverse chargings of second resistance R, first capacitor C, 1 negative pole, i.e. 2 times terminal potentials of second resistance R; Because of forming loop current through the 3rd diode D3 and the 6th resistance R 6 simultaneously; Keep than active potential V1 (the 3rd diode D3 is anodal), this current potential is not enough to satisfy the conducting-state voltage of the second diode D2 and the 3rd aerotron Q1, then first aerotron Q1 collecting electrode C and the not conducting of emitter E.The second aerotron Q2 base stage no current, the second aerotron Q2 collecting electrode no-output then, not adhesive of relay J, rain shaving electrical machine low speed armature L end is kept through normally closed point and is connect reset motor P end.Rain shaving electrical machine is in braking mode.When wiper switch placed INT (wiper switch is shelves intermittently) shelves, wiper switch intermittently shelves INT connect positive pole.This moment, DC24V voltage was added in the 3rd diode D3 negative pole end through the 7th resistance R 7 and the 6th resistance R 6 dividing potential drop current limlitings, and the 3rd diode D3 negative pole end current potential is raised, and then anodal compelled the raising of the 3rd diode D3 is high voltage V2.This voltage is greater than the conducting-state voltage of the second diode D2 and the first aerotron Q1, and then the collector emitter of the first aerotron Q1 amplifies conducting, and spurring the second aerotron Q2 base stage has big electric current, then the collector emitter saturation conduction of the second aerotron Q2.
Power line voltage B (+) adds to relay J coil two ends, relay J adhesive through the second aerotron Q2 and the 4th diode D4.Rain shaving electrical machine low speed armature end L is thrown to the normal beginning by normal-closed end through relay buffering end, and Chang Kaiduan connects power line voltage B (+).At this moment rain shaving electrical machine low speed armature end L has directly connected power line voltage, and rain shaving electrical machine low speed armature powers up, and motor begins to rotate.The windscreen wiper arm begins wiper.Reset motor end P also and then begins to rotate, like Fig. 4, when reset motor end P by meeting negative pole district (little radian braking district); Go to when connecing positive polar region (big radian reset area); First capacitor C, 1 voltage, through P → R1 → C1 → D3 → R6 loop, positive charge is to approximate power line voltage.Rotate to little radian retarder location when connecing negative pole again up to reset motor end P; First capacitor C, 1 voltage is similar to+24V-0V voltage by former, changes 0V--24V into, and promptly first capacitor C, 1 former positive terminal potential becomes 0V; Then first capacitor C, 1 negative terminal current potential must be negative 24V; Make the 3rd diode D3, the second diode D2 positive pole be in negative bias, then the second diode D2 ends fully, and then the first aerotron Q1 ends; Then the first aerotron Q1 collector emitter does not have electric current, and the second diode Q2 base current is zero.The second diode Q2 ends, and relay J is because of no-voltage, and transfers release position to from attracting state.Be that relay J is broken off, scrape motor low speed armature end L and connect normal-closed end that P is connected with the reset motor end, motor is in the braking halted state.Therefore reset motor end P connects negative pole the time, and then first capacitor C 1 begins discharge through second resistance R 2 and first resistance R 1, and this discharge time is by the time constant decision of second resistance R 2 and first capacitor C 1; Set about 6-7 second; Become 0V up to first capacitor C, 1 voltage, and during the beginning reverse charging, this moment if wiper switch intermittently a shelves INT still connect correct time (being in intermittently shelves); Because of the 3rd diode D3 cathode voltage is raised, first capacitor C, 1 negative pole current potential meeting reverse charging is to high voltage V2.Thereby start little relay adhesive in the windscreen wiper device at intermittence once more, motor begins to change next circle, repeats intermittent use.This moment if wiper switch intermittently shelves INT break off (unsettled), then first capacitor C, 1 negative pole current potential can be limited in the low voltage V1 that second resistance R 2, the 3rd diode D3, the 6th resistance R 6 bleeder circuits set.And the V1 current potential is not enough to satisfy the second diode D2, the first aerotron Q1 conducting-state voltage, not adhesive of relay J then, and rain shaving electrical machine is in braking mode.
Spray switch Wa, this windscreen wiper intermittently device also have air regulator spray wiper function concurrently.When rain shaving electrical machine is in when stopping; By the logical switch Wa (connecing positive pulse) that once sprays; The spray motor is started working; Ejection is cleansing fluid the time, and power line voltage provides base stage conducting electric current through the first diode D1, the 3rd resistance R 3, the 4th resistance R 4, the 5th resistance R 5 to the first aerotron Q1, and to 2 chargings of second capacitor C.The then first aerotron Q1 conducting, and then the second aerotron Q2 conducting, the relay J adhesive, windscreen wiper is started working.When spray switch Wa connect just break off after; Because of connecing at spray switch Wa, second capacitor C 2 has been full of electric weight correct time; Provide first aerotron Q1 base current by 2 discharges of second capacitor C this moment, continues to keep rain shaving electrical machine work, and the decision of the 4th resistance R 4 and second capacitor C, 2 time constants is arranged; One or two all after date of windscreen wiper wiper quits work.To wipe the cleansing fluid on the front windshield glass off.
The 4 interference protection misoperations of the 4th capacitor C.The 4th diode D4, the 3rd capacitor C 3, the tenth resistance R 10 are formed protective circuits, prevent the second aerotron Q2 reverse breakdown.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement, these improve the protection domain that also should be regarded as the utility model.
