Full-height foam sandwich unmanned aerial vehicle elevator rudder surface rotating shaft mounting mechanism

Abstract

The invention provides a full-height foam sandwich unmanned aerial vehicle elevator rudder surface rotating shaft mounting mechanism, comprising a stabilizing surface, a rudder surface and rudder surface end ribs, wherein the two rudder surface end ribs are plate-shaped structures and are respectively fitted on two sides of the rudder surface; The two stabilizer end ribs are plate-like structures,respectively fitted on the two sides of the stabilizer, and extend out projections toward the rudder end ribs; The distance between the two projections is greater than the distance between the two rudder end ribs; At that same side, the end rib of the rudder surface and the bump are connected through a rotating shaft mounting mechanism to further connect the stabilizing surface and the rudder surface; The two rotating shaft mounting mechanisms are coaxially arranged; A joint bearing is arranged in the rotating shaft mounting mechanism to adjust the coaxiality of the rotating shaft of the rudder surface and the mounting seat in the rotating shaft mounting mechanism so as to ensure the precise deflection of the rudder surface. The invention has the advantages of small number of parts, simple production and greatly simplified production process.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles and relates to a rotating shaft installation mechanism for an elevator rudder surface of an unmanned aerial vehicle, in particular to an installation mechanism for a rotating shaft of a full-height foam sandwich UAV elevator rudder surface. Background technique [0002] UAVs have been vigorously developed due to their low cost, quick response, and diverse tasks. In the military field, UAVs have been widely used in battlefield situation awareness, ground / air fire guidance, artillery correction shooting, and damage effect assessment; in the civilian field, UAVs have also covered power inspections, emergency rescue, and resource Industrial applications such as exploration and environmental monitoring. [0003] The UAV's horizontal tail is designed with an elevator rudder surface. During the flight, the UAV relies on the deflection of the rudder surface to generate a lifting moment, thereby co...

AI Technical Summary

Problems solved by technology

The former has a large number of parts, and the rudder surface closure process is complicated, and the rudder surface closure and the stabilizer surface closure are serial, and the manufacturing cycle is long when the UAV is mass-produced.

The flexible shaft of the latter is easy to cause the deflection angle deviation of the rudder surface at different cross-sections. When the rudder surface has a large spread, it is difficult to achieve precise control of the deflection angle only by relying on the mechanical structure, and when the rudder surface deflects at a large angle, it is easy to cause The fiberglass shaft is damaged and delaminated
