A motor actuating cylinder integrated cargo door opening mechanism comprises two suspension arms on left and right sides of a cargo door. The upper portion of each suspension arm is in hinged connection with a body structure through a supporting seat while the lower portion is in hinged connection with one end of a lower connecting rod, and the other end of each lower connecting rod is in hinged connection with a cargo door structure in a cargo door opening stage. The two suspension arms are in hinged connection with a coordination shaft, a motor component is in hinged connection with the bodystructure through a supporting seat, and an actuating cylinder is fixedly connected with the coordination shaft and stretches out or retracts to drive the coordination shaft to move so as to drive the two suspension arms to move synchronously. One end of an upper connecting rod is fixedly connected with the coordination shaft while the other end is in hinged connection with the cargo door structure in a cargo door opening stage. The upper connecting rods, the lower connecting rods, the two suspension arms and the cargo door structure form a four-link mechanism. By the structure, technical problems of excessive transmission links, complex parts and complexity in assembly in the prior art are solved, and the cargo door opening mechanism simple in mechanism and direct in transmission is provided.
Description
technical field [0001] The invention relates to the field of cabin door mechanisms of passenger aircraft, in particular to a mechanism installed on a semi-blocked flip-type cargo cabin door for realizing the opening movement of the cabin door. Background technique [0002] The design of the civil aircraft door mechanism requires simple transmission, few parts, small space occupation, and light weight. At the same time, the reliability and safety of the mechanism must also be considered. At present, for the semi-blocked cargo doors that are lifted upwards and inwards and turned outwards, in order to realize the opening movement of the doors, most of them use a set of opening mechanism and a set of driving mechanisms. The opening mechanism is used to control the turning movement of the hatch. track, the drive mechanism provides the power source for the opening of the hatch. The invention creates a cargo door opening mechanism that uses the motor as the power source and integr...
