Quad-rotor unmanned aerial vehicle with pure belt drive

Abstract

The invention discloses an oil drive unmanned aerial vehicle with pure belt drive. The oil drive unmanned aerial vehicle with the pure belt drive comprises a vehicle body, a drive device, four rotor wings and a pure belt drive system, wherein the drive device is arranged on the vehicle body, the four rotor wings are rotatably installed on the vehicle body, and the pure belt drive system is connected between the drive device and the rotor wings in a driving mode. The pure belt drive system comprises four groups of pure belt drive assemblies, wherein each group of the pure belt drive assembly and each rotor wing are connected between the drive device and the rotor wings in a one-to-one correspondence and driving mode. The drive device comprises a rotary shaft I, an engine, and a quadruple belt wheel set, wherein the rotary shaft I is rotatably arranged on the vehicle body in the vertical direction, the motor is fixed to the vehicle body and an output shaft of the engine is matched with one end of the rotary shaft I in a driving mode, and the rotary shaft I is fixedly sleeved with the quadruple belt wheel set which is used for driving the four groups of pure belt drive assemblies to operate simultaneously. Through the interaction of all components, not only can the quantity of the engine and the weight of the overall vehicle body be reduced, the cruising ability is increased, thefailure rate is reduced, maintenance and carrying are convenient, but also the manufacturing cost can be reduced, and better popularization performance can be achieved.

Description

technical field [0001] The invention relates to the field of aircraft manufacturing, in particular to a pure belt-driven four-rotor unmanned aerial vehicle. Background technique [0002] In recent years, the quadrotor market has developed rapidly, and various uses of quadrotors have been continuously explored. For example, plant protection and line inspection are now widely used. However, for the long-distance flight requirements, the quadrotors currently relying on electric drive are limited by the battery capacity, which is difficult to achieve. The high energy density and high endurance of traditional fuel engines can guarantee the long-term endurance of quadrotors. Some existing oil-powered drones use multiple engines to provide power, and each engine drives a rotor. This structure does not require a transmission, but the number of engines makes the failure rate high, which is not suitable for maintenance, and increases the overall weight of the fuselage. .

AI Technical Summary

Problems solved by technology

Some existing oil-powered drones use multiple engines to provide power, and each engine drives a rotor. This structure does not require a transmission, but the number of engines makes the failure rate high, which is not suitable for maintenance, and increases the overall weight of the fuselage.

Some inventions use a single engine but use all gears or gears with belt transmission, which increases the weight of the transmission system of the fuselage and weakens its battery life, and a large number of gear transmissions increase its overall cost and poor promotion.

At the same time, the existing long-endurance engines have the disadvantages of being bulky and inconvenient to carry, and the transportation is extremely inconvenient, which limits their application range
