Abstract

The embodiment of the invention discloses an unmanned aerial vehicle shape maintaining hatch cover hinge structure. The aerial vehicle shape maintaining hatch cover hinge structure comprises a hinge installation substrate, a first hinge rotary shaft, an abdicating rocking arm, a second hinge rotary shaft, and a range increasing rocking arm; the hinge installation substrate is arranged on the innerside of a vehicle body; the first hinge rotary shaft is arranged on the hinge installation substrate and can rotate relative to the hinge installation substrate; one end of the abdicating rocking armis connected with the first hinge rotary shaft; the second hinge rotary shaft is arranged at the other end of the second hinge rotary shaft; one side, towards the vehicle body, of a hatch cover is connected with the range increasing rocking arm; the hatch cover is close to or away from an opening via the range increasing rocking arm and the abdicating rocking arm; and when the hatch cover overlays the opening, the abdicating rocking arm and the range increasing rocking arm are inside the vehicle body. The unmanned aerial vehicle shape maintaining hatch cover hinge structure can realize large-angle opening / closing of the hatch cover of an unmanned aerial vehicle under a condition that no damage is caused to the pneumatic outer shape of the surface of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a hinge structure for a conformal hatch cover of an unmanned aerial vehicle. Background technique [0002] In the UAV design requirements, for the purpose of daily maintenance, carrying equipment, mission delivery, etc., UAVs need to open the necessary hatches on the fuselage. The opening and closing of the hatch cover involves the hinge structure. The existing conventional hinge structure has interference problems between the rotating shaft, the rocker arm and the fuselage skin. Skinned outer surface. This destroys the original smooth aerodynamic shape of the fuselage skin and increases the air resistance of the drone. [0003] Therefore, it is necessary to develop a UAV conformal hatch hinge structure that can realize the large-angle opening and closing of the UAV hatch without destroying the aerodynamic shape of the UAV surface. [0004] The information disclosed in the background o...
