Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] see Figure 1-Figure 6 , is a rotor drone 100 provided by the present invention. The rotor UAV 100 provided by the present invention can use the mechanical energy generated by the rotation of the blades 33 to be converted into electrical energy while stopping the consumption of the battery 20 during the descent, and store it in the battery of the rotor UAV 100. The battery 20 is reversely charged, thereby effectively improving the endurance of the rotor drone 100 .

[0026] Further, as figure 1 As shown, a rotor drone 100 provided by the present invention includes a frame 10 , a battery 2...

Abstract

The invention provides a rotor unmanned aerial vehicle. The unmanned aerial vehicle comprises a rack, a battery and a control module, wherein the rack is provided with at least four paddle arms, the rotor unmanned aerial vehicle further comprises at least four paddle assemblies, and each paddle assembly comprises a charging and discharging motor, a rotating shell arranged on an output shaft of the charging and discharging motor in a sleeving mode and paddles; the paddle assembly further comprises a paddle changing assembly which is arranged in the rotating shell and drives the paddle to rotate around the center shaft. According to the rotor unmanned aerial vehicle provided by the invention, the pitch angles of the blades can be changed by the variable pitch assemblies, and in the descending process of the unmanned aerial vehicle, the blades can be always kept in a rotating state in the descending process by adjusting the pitch angles of the blades; and meanwhile, a working mode of the charging and discharging motor is switched along with the change of the pitch angle of the blades, and the discharging mode of the charging and discharging motor is switched into the charging mode through the control module, so the battery is reversely charged by utilizing the autonomous rotation of the blades in the descending process. The invention further provides a method for prolonging the endurance of the rotor unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a rotor unmanned aerial vehicle and a method for extending the battery life of the rotor unmanned aerial vehicle. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment and its own program. UAVs are widely used in various fields because of their small size, low cost and convenient use. As UAVs are favored by the market, the endurance of UAVs has become an urgent problem in the development process. On the premise that the energy battery has not significantly broken through the technical barriers, if the UAV improves its battery life by increasing the battery capacity, the increased battery weight will also directly affect the UAV's battery life. At the same time, the existing research on the endurance of UAVs still stays in airfoil optimization and program control, improving the aerodynamic layout and structural la...
