CABIN DOOR DRIVING ASSEMBLY, UNDERCARRIAGE CABIN DOOR ASSEMBLY, AND CABIN DOOR DRIVING ASSEMBLY DESIGN METHOD

WIPO Patent Application WO/2023/142637

A1

The purpose of the present invention is to provide a cabin door driving assembly, an undercarriage cabin door assembly, and a cabin door driving assembly design method. In order to achieve the purpose, the cabin door driving assembly comprises an actuating unit and a pair of pull rods; the actuating unit comprises a rod member capable of linear displacement; one end of each pull rod and an end portion of the rod member are connected to each other in a relatively rotatable manner, and the other end of each pull rod is used for being connected to a cabin door. The cabin door driving assembly in this configuration is simple in structure, and easy to implement and assemble. In addition, compared with a mode in which a plurality of connecting points are arranged in an existing cabin door driving assembly, the number of connecting points in the cabin door driving assembly described in the present application is less, and compared with an existing solution, the later damage probability of the cabin door driving assembly is lower, so that the maintenance cost can be reduced.
