Abstract

The invention discloses a transmission mechanism applied to a multi-rotor UAV, which belongs to the technical field of UAVs, and comprises: a first belt transmission device, which is fixed on a frame and is respectively movably connected with rotor groups; and a second belt transmission device. The second belt transmission device is fixed on the frame and is respectively movably connected with the rotor group; wherein, the first belt transmission device is sleeved on the first shaft, and the rotation of the first shaft drives the first belt transmission device. The device is driven to drive each rotor in the rotor group that is movably connected with the first belt device to rotate; the second belt transmission device is sleeved on the second shaft, and the rotation of the second shaft drives the second belt transmission device for transmission , so as to drive each rotor in the rotor group movably connected with the second belt device to rotate. The invention realizes the rotation of the rotor driven by the engine in the multi-rotor UAV, and has the characteristics of simple structure and wide applicability.

Description

technical field [0001] The invention belongs to the technical field of drones, in particular to a transmission mechanism applied to multi-rotor drones. Background technique [0002] Unmanned Aerial Vehicle (English abbreviation: Unmanned Aerial Vehicle) is an unmanned aircraft that is controlled by radio remote control or by its own program. [0003] Most of the UAVs in the prior art are electric UAVs, which mainly use main components such as batteries, ESCs, motors, flight controllers, and propellers. The flight control of UAVs is realized by changing the speed of each propeller. However, due to the limitation of battery energy density, this type of electric UAV generally has a very short flight time and has the disadvantage of poor endurance performance, and the method of simply increasing the number of batteries to improve its flight time will also be greatly improved. reduce its load capacity. Therefore, it has become a new concept to replace the electric UAV with an e...
