An engine vibration damping structure for an oil-powered UAV

Abstract

An engine vibration reduction structure for an oil-powered drone, including four tripods supporting the engine. The four tripods are respectively supported on four mounting platforms through damping dampers. The four tripods pass through each other. The connecting rods are connected as one body. By installing four tripods through four installation platforms, the present invention minimizes the contact points between the engine and the fuselage bracket, thereby reducing the number of supporting structures. Moreover, the four tripods are connected into a rigid whole to increase the load-bearing capacity, avoid unnecessary structural reinforcement, and minimize the added weight while reducing vibration. Damping shock absorbers are installed at the four mounting platforms and four tripods to isolate the vibration of the engine operation from the fuselage bracket as much as possible, thereby isolating the engine on an independent frame to avoid the adverse effects of engine vibration on other components. In particular, it can protect the compactly arranged fuel tank and electronic equipment in the small space inside the drone from the impact of engine vibration.

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
