Technical Field

The invention relates to the technical field of unmanned aerial vehicle blades, in particular to a self-rotating quick-release blade base.

Background

The oar seat of unmanned aerial vehicle paddle at present in the market divide into fixed oar seat structure and from rotating oar seat structure. Fixed oar seat structure: the propeller base is fixed on the motor by four screws or the motor is provided with a proper mounting hole, the propeller base is not needed, and then the propeller is fixed on the propeller base motor by the four screws through the pressing plate. The paddle seat structure needs to frequently assemble and disassemble a large number of screws each time the paddle seat structure is installed and used, consumes time and labor, and can have thread sliding after being repeatedly used for a long time. Meanwhile, due to the fact that no definite positioning point exists, whether the propeller and the motor are concentric or not is mainly determined, and machining precision of the propeller base and errors during manual operation are eliminated. The self-rotating propeller fixing structure is fixed through a self-rotating propeller base, one is that a lower plate part of the self-rotating propeller base is fixed on a motor through screws, an upper cover part is fixed on a propeller through a pressing plate through screws and then is connected by the threads of the self-rotating propeller base, and the self-rotating propeller fixing structure is generally suitable for large-size propellers; the other type is that the propeller base is provided with a threaded output shaft or the output shaft of the motor is directly threaded, the propeller base is not needed, the propeller is sleeved on the output shaft and then is fixed through a bullet nut or a common nut, and the propeller is generally suitable for small-size propellers. The self-rotating fixed structure has fixed rotating directions, and the positive and negative propellers need to be provided with propeller bases with different rotating directions. When the motor rotates reversely, suddenly stops or stalls, the paddle seat has the possibility of falling off in the air such as loosening and shooting the paddles.

To the above-mentioned two kinds of circumstances, people developed from rotating quick detach oar seat, its structure comprises lower piece and the upper block that combines with the screw that combines with the motor, lower piece has the base of connection at the motor upper cover, the upper block has the nut and the upper plate that can tighten, can press down the rotation with the nut during dismantlement and loosen and can loosen the fixed nut of fixture block, back out the upper plate again can accomplish, it is rotatory to press down the nut again as long as screw up the upper plate during installation, send into the fixture block the draw-in groove and loosen and can accomplish, realize the combined use of screw and motor, can realize quick installation and dismantlement, and it is fixed to possess the nut buckle and screw up the upper plate, double insurance, the drawback and the easy installation dismantlement of formula oar seat from rotating have been solved. However, the positioning is unreliable, for example, if a certain paddle has a deviation, the eccentricity of the paddle can occur under a high rotating speed, and even the dropping of the paddle can occur when the eccentricity is serious; meanwhile, the axial and radial positioning deviation between the paddle and the motor cannot be eliminated, and the vibration problem of the paddle cannot be solved.
