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 incorporates first terminal connected to plus of storage battery of automobile, second terminal linked to minus of storage battery, third and fourth terminals connected to immobile contacts of microswitch controlling motoreduction gear which mobile contact is connected to minus of storage battery, fifth and sixth terminals to which electric motors of motoreduction gear setting in motion mechanisms of interlocking of locks are connected, first and second amplifiers inserted correspondingly between first and third and first and fourth terminals. Output stages of amplifiers are manufactured on electromagnetic relays which first immobile contacts are linked to first terminal and which second immobile contacts to which mobile contacts of each relays are closed normally are connected to second terminal, each via own diode to reduce drop of voltage in load circuit of unit and to simplifying design. Unit also includes time-setting network - timer connected to input of first amplifier. EFFECT: reduced drop of voltage and simplified design of unit. 8 cl, 1 dwg
