An engine vibration damping structure for an oil-powered UAV

Abstract

An engine vibration reduction structure of an oil-powered unmanned aerial vehicle comprises four foot frames supporting an engine. The four foot frames are supported on four mounting tables through damping dampers respectively, and the four foot frames are connected to be a whole through connecting rods. The four foot frames are mounted through the four mounting tables, so that contact points of the engine and a fuselage bracket are reduced as far as possible, to reduce the number of supporting structures. The four foot frames are connected to be a rigid whole, to improve the load capacity, avoid unnecessary structural reinforcement, and minimize the added weight while damping. The damping dampers are disposed at the positions of the four mounting tables and the four foot frames, so that the vibration during operation of the engine is separated from the fuselage bracket as far as possible, and the engine is isolated on an independent frame, thereby avoiding the adverse influence of thevibration of the engine on other components and protecting a fuel tank and an electronic device in compact layout in a narrow space in the unmanned aerial vehicle from the influence of the vibrationof the engine.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor oil-powered unmanned aerial vehicle, and in particular to an engine vibration-damping structure for an oil-powered unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. Civilian drones are widely used in aerial photography, agriculture, plant protection, micro-selfie, express transportation, disaster relief, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting and other fields.

Problems solved by technology

[0008] This prior art effectively overcomes the defective of prior art, but still there is room for improvement

This existing technology only provides a structure for dissipating heat from the engine, but it does not consider the impact of the huge vibration of the engine on the structural strength of the drone and other internal structures, especially for the compact space in the small space inside the drone. Layout of fuel tanks, electronics, technical solutions to reduce the impact of engine vibrations need to be provided and the weight gain to solve this problem needs to be minimized
