The invention discloses a hybrid power driving device and an unmanned aerial vehicle. The hybrid power driving device comprises an engine, a power distribution module, a plurality of main electric driving units and an auxiliary electric driving unit, wherein a plurality of main electric driving units are respectively connected with a plurality of rotor wings of the unmanned aerial vehicle, the power distribution module comprises a plurality of transmission mechanisms connected in sequence, the transmission mechanism comprises a planet carrier, a planet gear, a sun gear and a transmission gear,the planet carrier of the first transmission mechanism is connected with an engine, starting from the first transmission mechanism, the sun gear of the previous transmission mechanism is connected with the planet carrier of the next transmission mechanism, and the sun gear of the last transmission mechanism is connected with an auxiliary electric driving unit. The hybrid power driving device is advantaged in that the engine can directly drive the rotor wings of the unmanned aerial vehicle to rotate through the power distribution module, compared with the mode that the engine generates power firstly and then is electrically driven, higher energy conversion efficiency is achieved; due to the fact that a power generation system is omitted, the whole machine is lighter in weight and smaller in size, and cost is saved.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a hybrid drive device and an unmanned aerial vehicle. Background technique [0002] The problem of battery life is the most important and fatal shortcoming of drones, which greatly limits the development of the industry. Solving the problem of drone battery life is imminent. The drones on the market mainly use lithium polymer batteries as the main power, and the endurance is generally about 30 minutes. In particular, multi-rotor UAVs are the best consumer and commercial models among UAVs, mainly electric. However, lithium batteries have shortcomings such as low energy density and short service life, resulting in short flight time and short range of UAVs, which seriously restricts the development of multi-rotor UAVs in various fields. [0003] The power system of the UAV determines the lasting state of the endurance. According to the different power sources, it...
