Problems solved by technology

However, the rudder surface of the UAV is generally located at the trailing edge of the wing surface, where the space inside the wing is narrow, and the general rudder surface control mechanism must ensure that there are no exposed parts and not destroy the original aerodynamic shape of the UAV, which is difficult to achieve

Abstract

The invention discloses an embedded unmanned aerial vehicle steering surface control device. The embedded unmanned aerial vehicle steering surface control device is composed of a steering engine, a driving gear, a transmission gear and a driven gear. The steering gear and a driving gear mounting support are fixed in a wing. The steering gear is positioned at one side of the driving gear mounting support. The driving gear and the transmission gear are mounted in the middle of the driving gear mounting support for meshing transmission. A steering engine connecting sleeve sleeves a steering engine gear, is connected with the steering engine and is matched with a rotating shaft of the driving gear. The driven gear and a gear mounting block are connected and located in a steering surface. A rotating shaft of the driven gear coincides with a rotating shaft of the steering surface. The driven gear and the transmission gear are meshed at the clearance between a vehicle wing rear edge and a steering surface front edge. The steering engine drives the driving gear to rotate. The driving gear is meshed with the transmission gear and drives the driven gear to rotate through the transmission gear so as to drive the steering surface to rotate. The steering surface control device has no exposed parts and is convenient to install. The control precision can be adjusted by changing the number ofteeth of each gear and adjusting the transmission ratio of the steering gear and the steering surface.

Description

[0001] Field [0002] The invention relates to the field of unmanned aerial vehicles and automatic control, in particular to a built-in unmanned aerial vehicle rudder surface control device. Background technique [0003] At present, UAVs have been widely used in both civilian and military fields. Among them, fixed-wing UAVs have been widely used. The rudder surface of a fixed-wing UAV generally includes flaps and ailerons on the wings, elevators on the horizontal tail and rudders on the vertical tail, which are used to control the aircraft. [0004] The rudder surface control mechanism of fixed-wing drones generally uses exposed rocker arms and connecting rods to connect the steering gear and rudder surface for rudder surface control. This rudder surface control mechanism increases the exposed area of ​​the body. Although it can rectify the exposed part, it still destroys the original aerodynamic shape of the drone and reduces the lift-to-drag ratio of the drone. If one end...
