Description

Unmanned aerial vehicle screw each other inlays buckle formula dual fail-safe quick assembly disassembly structure

Technical Field

The utility model relates to an unmanned air vehicle technique field, concretely relates to unmanned aerial vehicle screw each other inlays buckle formula dual fail-safe quick assembly disassembly structure.

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 without the propeller base), and then the propeller is fixed on the propeller base (the motor) by four screws through the pressure 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 motor output shaft is directly threaded without the propeller base), 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 above-mentioned two kinds of circumstances, people developed quick detach formula oar seat, its structure comprises with the lower piece that the motor combines and the last piece that combines with the screw, the piece has two location pivot pins that can press on, pivot position level is placed, can be translational motion at the horizontal direction of pivot when pressing, it has two location pivot pins that four jack catchs can catch on the piece to have fast down, the pivot is inwards removed when pressing the button at piece both ends on the piece, the jack catch realizes breaking away from the pivot of piece and can realize tearing open and adorning, can block the jack catch through the pivot when loosening, realize the fixed of screw and motor, can cross to realize quick installation and dismantlement. However, the positioning accuracy is not accurate, for example, if a certain paddle has a deviation, the eccentricity of the paddle can occur under a high rotating speed, even the claw is broken when the eccentricity is serious, and finally the dropping of the paddle can occur; 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. And it requires high machining accuracy, resulting in high manufacturing costs.
