Problems solved by technology

However, the folding of the existing propellers is only to bring together several scattered propellers. The assembled propellers have no additional fixed structure, and they rotate under the gravity of the propellers during packaging. At this time, the propellers will rotate and are not easy to fold.

Abstract

The invention discloses a power assembly and a rotorcraft. The power assembly comprises a motor, a propeller connected with the motor and a limit unit, wherein the motor is mounted on a motor base ofa rotor UAV (unmanned aerial vehicle), the limit unit is arranged on the motor base or an arm or a foot rest of the rotor UAV, the propeller has an unfolding position and a folding position, and whenthe propeller is in the folding position, the limit unit can be connected with the folded propeller and limit the propeller in the folding position; when the propeller is in the unfolding position, the limit unit is separated from the propeller. By means of the limit unit, the propeller can be limited in the folding position and cannot rotate freely when the rotorcraft is folded for packaging, andpackaging is facilitated; the limit unit is arranged on the motor base, the arm or the foot rest, so that the limit unit cannot be separated from the rotor UAV when not in use and can be effectivelyprevented from getting lost.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a power assembly and a rotorcraft. Background technique [0002] With the rapid development of rotorcraft technology, rotorcraft are gradually used in various industries, such as civil, navigation, aviation and so on. The rotorcraft is driven by a power assembly. The power assembly generally includes a drive mechanism and a propeller. The propeller is fixedly connected to the drive mechanism. [0003] At present, for the convenience of storage and transportation, the rotorcraft is usually set in a foldable structure, and the propeller which takes up a large space will also be set in a foldable structure. However, the folding of the existing propellers is only to bring together several scattered propellers. The assembled propellers have no additional fixed structure, and they rotate under the gravity of the propellers during packaging. At this time, the propeller...
