Unmanned aerial vehicle control plane drive mechanism

Abstract

The invention discloses an unmanned aerial vehicle control plane drive mechanism. Drive of an elevator with a horizontal tail is taken as an example. The drive mechanism comprises the elevator, a Y-shaped chuck, an elevator rotary shaft, a rocker arm, an elevating steering engine, a horizontal stabilizer, a control plane clip, a horizontal tail steering engine seat and a vertical fin. The Y-shapedchuck is arranged on one side of the elevator and provided with the elevator rotary shaft. The rocker arm is arranged on the elevating steering engine and provided with the control plane clip. The mode that a control plane is directly driven through the rocker arm and the control plane clip is adopted by the steering engine, and the clearance of the control plane in the drive process is reduced;the steering engine is buried in a wing or a flat vertical tail stabilizer, the mechanism cannot be exposed, the appearance of the wing or the flat vertical tail is simpler, and the flight resistanceis smaller; the drive mode is simple and direct, various types of resistance in the transmission process is reduced, the steering engine load is reduced, and meanwhile the reliability of the mechanismis improved; and the control plane of the mechanism is convenient to detach, install and replace.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to an unmanned aerial vehicle rudder surface driving mechanism. Background technique [0002] Unmanned aircraft is referred to as "UAV" for short, and the English abbreviation is "UAV". It is an unmanned aircraft controlled by radio remote control equipment and its own program control device. Compared with manned aircraft, it has the advantages of small size, low cost, convenient use, low requirements for combat environment, and strong battlefield survivability. Due to its various advantages over manned aircraft, vehicles and other equipment, drones have played an increasingly important role in people's production, life and military affairs. The traditional UAV rudder surface drive mechanism generally adopts the rocker-tie rod-rudder foot scheme. Taking the aileron as an example, the steering gear is generally embedded in the wing, and the rocker arm connected to the steering gear exte...

AI Technical Summary

Problems solved by technology

If the existing technology adopts the scheme of rocker arm-tie rod-rudder foot, during use, due to the installation angle and position error, the driving resistance will generally be generated, resulting in an increase in the load of the steering gear

Moreover, there are many parts required for the transmission, which often produces a certain vacant position, which makes the control of the UAV delayed.

The increase in parts also leads to a decrease in reliability and complicated rudder surface disassembly and replacement

Due to the leakage of the drive transmission mechanism in this solution, a certain amount of flight resistance will be generated during flight, and the appearance of the drone is not simple and beautiful.

The leaky mechanism brings inconvenience to the transportation of UAV wings, horizontal / vertical tail and other components
