Automobile headlight circuit txoj cai
Lub tsheb headlight Circuit Court muaj keyboards, kab, fuses, relays thiab lwm yam khoom, fuse tswj relay ntawm tam sim no loj, hloov tswj relay ntawm me me tam sim no, thov zam txim rau kuv qhov tam sim no me me muaj fuse tswj? Thov muab cov lus piav qhia tshwj xeeb rau kuv. Ua tsaug
Kuv qhia qhia los teb
Cov qog nqaij hlav twg yuav kis mus rau lwm tiam neeg?
Cov kev paub niaj hnub ntawm kev kawm science thiab thev naus laus zis yog cov ntaub ntawv zoo heev
· Zoo ntawm kev tshawb fawb thiab thev naus laus zis, lub zog tshiab ntsig txog thev naus laus zis, thiab tshawb fawb keeb kwm thiab kab lis kev cai.
Tsom ntsoov rau
Daim duab qhia tau hais tias nws pib taws teeb tswj Circuit Court. Tus maub los yog tsim los ntawm ib qho kev ruaj khov qeeb Circuit Court (IC1, Rl, R2, RD, C1), ntau lub vibrators (IC2, R3, R4, C2), kev sib txuas hluav taws xob tswj hluav taws xob Circuit Court IC3 (7812), V-MOS lub zog tsav tube BG2 , BG3 thiab lwm yam, ntsig txog kev tsav tsheb ob lub teeb ntawm lub tsheb.
Tus maub los yog siv los ntawm lub tsheb roj teeb + 24V thiab muab DC voltage ntawm VDD = + 12V rau IC1 thiab IC2 tom qab voltage tswj los ntawm IC3. Thaum sab pem hauv ntej tsis txav mus rau tib qho kev taw qhia, cov photosensitive kuj RD yog siab vim nws tsis raug rau lub teeb, thiab cov IC1 sib raug zoo yog rov pib dua vim qhov siab ntawm ko taw thiab qib qis ntawm ko taw.
