RECLINING SLIDING DOOR WITH ELECTRIC SCREW DRIVE Russian patent published in 2022 - IPC B61D19/02 E05F15/60 

FIELD: transport engineering.

SUBSTANCE: invention relates to the field of transport engineering, and in particular to the designs of drives sliding doors of passenger vehicles. Reclining-sliding door with an electric screw drive, having at least one leaf in the opening of the body of a passenger vehicle, an electric screw drive of the leaf installed above the frame of the opening, consisting of a base with walls, a lead screw in bearings placed in the side walls with a lead nut; motor-reducer on one of the walls of the base; a controlled clutch, the fixed body of which is fixed on one of the side walls, and the movable part is connected to the lead screw; a door guide installed in the side walls of the base, a carriage mounted on the guide for movement connected to the bracket for fastening the upper part of the door; connection of the lead nut with the carriage, ensuring their joint movement during the rotation of the lead screw; connections of the carriage with the door leaf; means that ensure the extension of the door when the lead screw starts to rotate to open the door and the leaning movement of the door to the frame of the opening when the door is closed; means that ensure the movement of the door extended from the opening parallel to the outer wall of the vehicle when the door is opened and the closed door is fixed in the frame of the opening. The running nut is in the form of a single-arm lever with a threaded hole for the lead screw, the carriage is in the form of a two-arm lever with a hole for the guide and the angle between the arms of the carriage levers is in the range of 70°…110°. The nut lever and the first arm of the carriage lever facing the nut are connected with the possibility of rotation through an angle of 10°…20° relative to the line connecting the axis of the lead screw and the guide. The connection of the carriage with the sash has a bracket fixedly connected to the sash and movably connected to the end of the second arm of the two-arm carriage lever.

EFFECT: simplification of the design of the electric screw drive of the reclining-sliding door is provided.
