Abstract

The invention involves a rotor system and drone that prevents the line. The rotor system of the prevents lines of the present invention includes propellers, rotating drivers, installation brackets, first steering gear, second steering gear and machine arm, first firstThe steering gear is used to drive the rotating driver to rotate around the X direction; the second steering gear is used to drive the first steering gear to rotate around the Y direction; of which, the X direction and Y direction are perpendicular to each other.There is a second steering machine disc on the steering gear. The second steering gear discs are fixed on the fixed -connection of the transmission parts.After passing through the bearing, the connecting tube is fixed with the arm of the machine, and the electric slip ring is located outside the connector. Among them, the rotating terminal of the electric slip ring is fixed with the connecting tube.There is a connection column above the bearing seat, and the connection board is fixed with the connection column.Therefore, this invention can solve the problem of easy tangled lines.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a rotor system and an unmanned aerial vehicle capable of preventing wire entanglement. Background technique [0002] Nowadays, the most widely used UAV is the quadrotor UAV, which uses the motor to drive the propeller to drive the aircraft to fly, and uses the speed difference of each propeller to realize various flight attitudes such as forward flight, inverted flight, left and right turns, etc. . Various functional devices are generally mounted under the aircraft, such as cameras, thermal sensors, etc., and the devices need to be connected to the gimbal to achieve a full range of monitoring vision from all angles. When it is moving, it can adjust the lift force by increasing or decreasing the speed of the motor at the same time, so that it can move in the vertical direction. If you want to move in the horizontal direction, you must obtain the force in the horizontal direction...
