Abstract

A blade fixing structure and an unmanned aerial vehicle are disclosed. The blade fixing structure is used for rapidly mounting a blade to a motor. The blade fixing structure includes a base includinga rotation limiting block having a shape matched with a mounting through hole, with the rotation limiting block being fixed to the motor; a blocking element including an upper blocking table connectedto the rotation limiting block; an axial limiting element rotatably disposed between the upper blocking table and the rotation limiting block, and having a shape matched with the mounting through hole; and an elastic element disposed between the axial limiting element and the blocking element, and pressing the axial limiting element against the rotation limiting block. According to the blade fixing structure, the blade can be rapidly dismounted.

Description

technical field [0001] The invention belongs to the technical field of flying devices, and in particular relates to a blade fixing structure and an unmanned aerial vehicle. Background technique [0002] The fast installation and disassembly of the existing UAV blades are usually fixed by positive and negative threads, or the positive and negative screw position is pressed against the limit card slot by the shrapnel. These two methods of quick installation, disassembly and fixing of the blades, when the motor decelerates too fast, because the blades still have a lot of kinetic energy to keep rotating, the paddles will fly out in the direction of loosening, posing a certain safety hazard. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a blade fixing structure, which can facilitate fast fixing of the blade and prevent the blade from flying...
