Equipment cabin door mechanism of thin-wall type complex surface modeling unmanned aerial vehicle

The invention relates to an equipment cabin door mechanism of a thin-wall type complex surface modeling unmanned aerial vehicle. The equipment cabin door mechanism consists of a hinge component, a rocker arm component and a locking component; a hinge in the hinge component is mounted on a fuselage skin through a rivet or a bolt, and the circular end of a plug pin in the locking component is arranged in the middle of a rocker arm in the rocker arm component in a sleeving mode; two ends of the rocker arm in the rocker arm component pass through a central circular hole of a hinge pin in the hinge component. The equipment cabin door mechanism is a suit of mechanism capable of realizing the functions of opening, closing and locking a cabin door according to the design of stressed-skin construction and the cabin door of the unmanned aerial vehicle. The mechanism adopts an articulated mechanism to connect the cabin door onto the fuselage skin, and the opening and the closing of the cabin door can be easily realized just by unlocking a safety lock, so that the defects that the opening and the closing of the cabin door can be realized by disassembling a great amount of quick-release bolts in a traditional method and the cabin door needs to be disassembled and removed frequently are effectively solved, and the efficiency, reliability and safety of using and maintaining the aerial vehicle are greatly improved.
