Rotor tilting device for four-axis unmanned aerial vehicle

Abstract

The invention relates to a rotor tilting device for a four-axis unmanned aerial vehicle. The rotor tilting device for the four-axis unmanned aerial vehicle comprises a steering engine device, a connecting rod device, a bearing and a frame connecting part; the steering engine device comprises a steering engine, a steering engine bracket and two locating rods, wherein the steering engine is clampedbetween the steering engine bracket and the frame connecting part; the two locating rods are correspondingly and vertically fixed on the two sides of the steering engine; the connecting rod device comprises an upper rocking bar, a lower rocking bar, a rotor connecting rod and two guide rods, wherein the lower rocking bar is connected with a steering engine steering disc; the two ends of the upperrocking bar and the lower rocking bar are correspondingly connected with each other through the guide rods; fixing grooves are correspondingly formed in the centers of the upper rocking bar and the lower rocking bar; the fixing groove of the upper rocking bar is in interference fit with the rotor connecting rod; and the rotor connecting rod penetrates through the frame connecting part and is fixedthrough a bearing. The rotor tilting device for the four-axis unmanned aerial vehicle has the advantages that greater forward flying thrust and rotating torque can be provided for the four-axis unmanned aerial vehicle, the cruising speed and maneuverability can be enhanced, tilting fine adjusting can be continuously generated, and the flight stability can be enhanced.

Description

technical field [0001] The invention relates to a rotor tilting device for a four-axis unmanned aerial vehicle, belonging to the technical field of unmanned aerial vehicles. Background technique [0002] Traditional quadrotor UAVs have always been the mainstream of small UAVs. Because of their advantages of symmetrical aerodynamic layout, strong wind resistance, large load, and easy control, they are currently widely used in many fields. But at the same time, due to its inherent structural reasons, the quadrotor UAV has poor maneuverability and insufficient endurance, which further limits its large-scale promotion and use in the military and civilian fields. At present, the existing solutions to the above problems mainly focus on two aspects, one is to increase the battery capacity within a limited range; the other is to optimize and adjust the flight control system, but the actual effect improvement is not obvious enough. Therefore, people began to explore new means to sol...
