UNIT CONTROLLING SYSTEM OF ELECTRICAL INTERLOCKING OF LOCKS OF DOORS Russian patent published in 1996 - IPC

FIELD: automobiles. SUBSTANCE: unit controlling system of electrical interlocking of locks of doors includes first terminal connected in automobile to plus of storage battery, second and third terminals connected to immobile contacts of microswitch of controlling motoreduction gear which mobile contact is linked to minus of storage battery, fourth and fifth terminals connected to immobile contacts of two-way button on instrument panel of automobile, sixth terminal linked to minus of storage battery, seventh and eighth terminals to which electric motors of motoreduction gear are connected which set in action mechanisms of interlocking of locks, first and second transistor amplifiers placed correspondingly between first and second and first and third terminals, RC time-setting circuit, capacitor connected with first lead-out to input of first amplifier and with second lead-out - to input of second amplifier, two resistors inserted correspondingly between first and second and first and third terminals. Fourth terminal is connected through stabilizer diode which stabilization voltage is 0.7-0.8 of storage battery voltage to third terminal and through diode - to first lead-out of capacitor. Fifth terminal is connected through similar stabilizer diode to second lead-out, through another diode - to second lead-out capacitor. Second and third terminals are connected through own diodes correspondingly to first and second leads-out of capacitor. EFFECT: improved operational reliability. 8 cl, 2 dwg
