Problems solved by technology

However, when the UAV is operating in the air, the engine drives the rotor to rotate extremely fast, the sweeping area of ​​the rotor is large, and the inertia of the fuselage and rotor is relatively large during the movement.
When the rotor is out of control, if it cannot be braked in time, its powerful destructive force may cause great harm to the ground crowd or buildings

Abstract

The invention provides an unmanned aerial vehicle (UAV) rotor braking system comprising a vehicle body, a motor and a rotor shaft. The motor is connected to the rotor shaft, and the UAV rotor brakingsystem further comprises a friction plate, two brake pads and two servers; the friction plate is fixedly connected to the middle part of the rotor shaft through a fixed disk, and the two brake pads are arranged on the both sides of the rotor shaft symmetrically, and connected to the two servers separately; and the UAV rotor braking system further comprises a height regulating mechanism connected to the servers. The UAV rotor braking system has the advantages of high brake response and efficiency, and improvement of stability during reducing transmission of a rotor; meanwhile, the height regulating mechanism is arranged, thereby facilitating height adjustment of the brake pads on the both sides of the rotor shaft; and the distortion and deformation phenomena of the friction plate in the braking process due to different position heights of the brake pads on the both sides of the rotor are avoided, and the service life of the friction plate is prolonged effectively.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle rotor braking system. Background technique [0002] With the development of UAV technology, especially the rapid development of UAV, its application is becoming wider and wider, and it is indispensable in both civilian and military fields. However, when the UAV is operating in the air, the engine drives the rotor to rotate extremely fast, the sweeping area of ​​the rotor is relatively large, and the fuselage and rotor have relatively large inertia during motion. When the rotor is out of control, if it cannot be braked in time, its powerful destructive force may cause great harm to the ground crowd or buildings. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a UAV rotor braking system with fast braking response, high efficiency and long service life. ...
