WINDOW REGULATOR WITH EVACUATION GLASS OPENING FOR ARMOURED VEHICLES Russian patent published in 2020 - IPC B60J1/17 F41H7/02 E05F11/46 

FIELD: machine building.

SUBSTANCE: invention relates to automotive industry, in particular to glass window with evacuation glass opening for armoured vehicles. Double scissor lifting-lowering mechanism is a system of levers connected in pairs by pivot. Upper levers are connected to support of lodgement of glass by means of sliding supports, lower - hinged, wherein one of them is attached to the movable support, the second - to the base, in which the carriage is installed, sliding along the guides together with the movable support. Drive of hoisting-lowering mechanism is electric by means of two motor-reducers and ball-screw gear with nut attached to carriage. Glass elevator has mechanical drive to actuate glass lifting and lowering mechanism in emergency situation, when on-board power supply is disconnected and there is no possibility to leave vehicle through doors. It represents a cable drive having a handle on the door inside the car, connected to the lever with a cam mechanism, pushing at the turn of the handle the hook, which is out of engagement with the carriage. On the axis of movement of the carriage and movable support of the lower lever there is a gas stop inside the carriage, which serves as a power accumulator for operation of the electric window regulator in an emergency situation. When the handle is turned and disengaged, rigid mechanical connection of the carriage and the support unit stops, which results in release of energy of the gas stop, which moves the movable support of the lever mechanism with force allowing to lower the glass. In order to return the mechanism to normal operating mode it is necessary to activate standard electric drive of window regulator in direction of lowering of glass. Carriage is set in motion corresponding to compression of the gas stop, and in the end there is mechanical mutual fixation of the carriage and movable support of the lever mechanism due to the hook.

EFFECT: providing operational reliability, compactness, uniformity of speed of raising and lowering glass and smooth operation both in normal operation mode and during rapid evacuation, and possibility to return mechanism to standard operation.
