A shock-absorbing protection device for an unmanned aerial vehicle engine

Abstract

The invention discloses a shock absorption protection device for an unmanned aerial vehicle engine. The device includes an engine protection plate and an unmanned aerial vehicle fixed plate, four openslots are radially arranged based on the fixed plate, and outer end magnetic pole faces of second magnets and outer end magnetic pole faces of first magnets are the same, so that in the novel structure, magnetic repulsive buffering force is always maintained between the engine and the unmanned aerial vehicle fixed plate; fixed round rods are matched with the open slots, limiting plates wrap outerends of the second magnets, and a fixed block is matched with an embedded groove, so that fixing between the engine protection plate and the unmanned aerial vehicle fixed plate in the novel structureis more convenient and rapid; and a buffering block and the unmanned aerial vehicle fixed plate are provided with limiting grooves based on limiting balls, rubber blocks are arranged on the limitinggrooves, and a contact surface of the fixed plate and the buffering block and contact surfaces of the fixed round rods and the open slots are provided with rubber spacers, so that the novel structurefully plays a role of shock absorption when maintaining protection of a plurality of structures.

Description

Technical field [0001] The invention relates to the technical field related to unmanned aerial vehicles, in particular to an unmanned aerial vehicle engine shock absorption protection device. Background technique [0002] In recent years, the UAV industry has developed rapidly. Whether it is an oil-powered UAV or a fixed-rotor UAV, when they are in use, they will be subject to the relative vibration between the engine and the UAV body. As a result, when drones are in use, there will be a series of factors that are not conducive to drone flight. For oil-powered UAVs, the working state of its internal engine is always in a state of vibration, which can be transmitted to all parts of the UAV through the fuselage; while for the fixed-rotor UAV, It has many rotating structures, the vibration source and vibration conditions are more complicated, and it is more sensitive to the vibration of the engine. Combining the two conditions, we know that this will also cause the UAV's requiremen...

Problems solved by technology

[0002] In recent years, the UAV industry has developed rapidly. Whether it is an oil-driven UAV or a fixed-rotor UAV, when they are in use, they will be subject to the relative vibration between the engine and the UAV body, which means As a result, when the drone is in use, there will be a series of factors that are not conducive to the flight of the drone

For oil-powered UAVs, the working state of the internal engine is always in a state of vibration, which can be transmitted to various parts of the UAV through the fuselage; and for fixed-rotor UAVs, due to It has many rotating structures, the vibration source and the vibration situation are more complicated, and it is more sensitive to the vibration of the engine. Combining the two situations, we know that this will also lead to the UAV’s requirements for engine vibration reduction. Because of its different structures, it presents different requirements, so we propose a UAV engine shock-absorbing protection device to solve the above problems
