DEVICE TO CONTROL VEHICLE DOOR OPENING AND CLOSING Russian patent published in 2006 - IPC E05F15/02 B60J5/00 

FIELD: mechanical engineering, particularly devices to control vehicle door opening and closing.

SUBSTANCE: device comprises controllable vacuum drive. The vacuum drive includes upper and lower semi-bodies divided with diaphragm and rigid centrators connected to both sides of the diaphragm and to shaft, as well as shaft guide extending through the body and provided with shaft seal. Shaft guide case is connected to lower semi-body and has pivot connected thereto. Friction bearing is installed in the shaft guide. Lower semi-body lid has orifice communicating with atmosphere through additional control throttle and normally opened two-port on-off electropneumatic distributor. Vacuum drive also has two three-port on-off distributors. One distributor is pneumatically connected with upper semi-body cavity, another one is communicated with lower semi-body interior through shaft guide case. Semi-body interiors are simultaneously communicated with differential vacuum switch. Pneumatic inlets of three-port on-of distributors are connected to inlet pipeline of combustion engine for vacuum creation. Vacuum drive control means is connected to the first three-port on-off distributor for door opening and with the second one for door closing. The vacuum drive control means is also linked to three-position switch to generate door opening/closing signal, to normally opened two-port on-off electropneumatic distributor for vacuum drive force reduction and to differential vacuum relay to provide door closing delay. The vacuum drive control means is also connected with final door location sensor.

EFFECT: increased passenger safety during vehicle door opening/closing.
