Damping mechanism for engine of oil drive rotor-wing unmanned aerial vehicle

Abstract

The invention discloses a damping mechanism for an engine of an oil drive rotor-wing unmanned aerial vehicle. The damping mechanism comprises an engine mounting structure and an unmanned aerial vehicle body; the engine mounting structure comprises the engine, an engine mounting plate, a plurality of trapezoidal connecting pillars and a damping plate; the upper portions of upper portion flanges of the trapezoidal connecting pillars are sleeved with axial rubber damping pads, and the multiple trapezoidal connecting pillars are upwards connected with the engine mounting plate through the rubber damping pads; an output shaft of the engine extends out from a through hole in middle of the damping plate; radial damping pads are mounted between the damping plate and the trapezoidal connecting pillars; a gear reduction box is connected to the unmanned aerial vehicle body through a plurality of flexible rubber damping pads; the output shaft of the engine is connected with the input end of the gear reduction box through a clutch; and the lower ends of the multiple trapezoidal connecting pillars are connected to an outer shell of the gear reduction box in a rigidity mode. According to the damping mechanism for the engine of the oil drive rotor-wing unmanned aerial vehicle, the problem that the flying and controlling effects are influenced by resonance of a current oil drive multi-rotor-wing unmanned aerial vehicle body and the engine is solved; and flying performance and safe stability of the oil drive multi-rotor-wing unmanned aerial vehicle can be promoted.

Description

technical field [0001] The invention belongs to the field of oil-operated rotor drones, and in particular relates to an engine damping mechanism of an oil-operated rotor drone. Background technique [0002] In recent years, the UAV industry has developed rapidly. Oil-powered UAVs have been vigorously developed in the industry because they are fuel-powered and do not need to be restricted by batteries like electric UAVs. However, because the engine used by the oil-powered UAV is always in a state of vibration in the working state, this vibration is transmitted to all parts of the UAV through the fuselage, which is very unfavorable for the work of the UAV, and affects flight stability at least. , and damage the body structure in severe cases. It even caused the drone to disintegrate during flight. For the single-cylinder or double-cylinder piston engines used by most oil-powered drones at present, the vibration in the working state is more severe. Therefore, it is necessary...
