The invention relates to an unmanned plane undercarriage cabin door retraction-extension servo mechanism. According to a technical scheme involved in the invention, the undercarriage cabin door retraction-extension servo mechanism is characterized by including: a bracket, one end of which is connected to an undercarriage and moves around an undercarriage rotating shaft; a push-pull rod assembly, the first end of which is connected to the bracket; a rocker arm assembly, the first end of which is connected to a second end of the push-pull rod assembly; a rocker arm assembly fixation lug, which is in fixed connection with the body and is hinged to the rocker arm assembly, with the rocker arm assembly rotating around the rocker arm assembly fixation lug; a rotating cylinder assembly, which is connected to a second end of the rocker arm assembly; and a cabin door connection assembly, which is connected to the rotating cylinder assembly and the undercarriage cabin door and drives the undercarriage cabin door to move. The unmanned plane undercarriage cabin door retraction-extension servo mechanism provided by the invention has the advantages of simple structure, light weight, and convenient adjustment.
Description
technical field [0001] The invention relates to the field of aviation aircraft mechanisms, in particular to an unmanned aerial vehicle landing gear door retractable follow-up mechanism. Background technique [0002] The landing gear door is part of the shape of the aircraft, and the door is open during the aircraft's taxiing, takeoff, and landing; when the landing gear is retracted during the flight of the aircraft, the landing gear door is closed and the landing gear compartment is closed to ensure the safety of the aircraft. Good aerodynamic shape in the air. The opening and closing of the hatch requires a set of specialized mechanisms to operate. [0003] The landing gear door retracting mechanism of manned aircraft generally has two forms: one is that the landing gear door is driven by a separate door retracting power, and is controlled by the program-controlled landing gear door retracting mechanism. The retractable mechanism of the landing gear door controlled by the...
