Abstract

The invention discloses a multi-rotor unmanned aerial vehicle blade capable of being disassembled and assembled rapidly. The multi-rotor unmanned aerial vehicle blade comprises a blade body, a self-locking member and a motor, wherein the top end of a rotor of the motor is provided with an optical shaft, the optical shaft passes through the rotor and is integrated with the rotor; the self-locking member is connected with the rotor through a bolt, and the inner wall of the self-locking member is provided with two self-locking protrusions; the outer portion of the blade body is provided with self-locking grooves and guide grooves which are matched with the self-locking member, and the middle of the inner portion of the blade body is provided with a cylinder with a variable-diameter hole; theoptical shaft is provided with a spring, and the lower portion of the spring is in interference fit connection with the self-locking member. When the self-locking protrusions press the blade body forrotation by being aligned with the guide grooves respectively, the self-locking protrusions enter the self-locking grooves and are self-locked here under the action of the spring. The multi-rotor unmanned aerial vehicle blade capable of being disassembled and assembled rapidly has the advantages that when the blade is installed, purely pressing and rotation of the blade are simply needed, the operation is simple and novel, a lot of time is saved for the installation of a multi-rotor unmanned aerial vehicle, and when the blade is disassemble, the operation is also convenient and fast without any tool.

Description

technical field [0001] The invention relates to the technical field of multi-rotor UAV accessories and blades, in particular to a rapidly detachable multi-rotor UAV blade. Background technique [0002] At present, multi-rotor drones are widely used in various fields such as electric power, transportation, agriculture, and fire protection due to their simple structure, high safety, and low cost of use. The multi-rotor UAV power system consists of batteries, ESCs, motors and propellers. Before and after use, the propellers need to be installed and disassembled. However, in the prior art, the blades are mostly fixed by screws, which is time-consuming and labor-intensive, and affects the installation efficiency. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention aims to provide a multi-rotor unmanned aerial vehicle blade that can be disassembled and assembled very conveniently and quickly and has a self-locking ...
