DETAILED DESCRIPTION

[0017] Example 1

[0018] As Figs. 1 to 5As shown, the utility model provides: a quick dismounting mechanism for unmanned aerial vehicle accessories, including paddle, locking structure, arm, wherein the paddle and arm are connected through locking structure, the upper part of locking structure is the plug installed in the bottom of paddle, locking hole is arranged at the joint of plug and locking structure, the lower part of plug locking structure is the socket installed in the upper part of arm, a plurality of connecting springs are connected on the socket, plug and socket are locked or separated through buckle structure, one side of buckle structure is the button for pressing, the button is connected with the push rod for applying the thrust, the other side of buckle structure is provided with the locking block for clamping into the locking hole, one side of locking block is connected with the connecting rod for being pushed by push rod, the bottom of buckle structure is provided with the limiting block for limiting the movement of locking block, locking spring is arranged around limiting block and locking block.

[0019] Among them, the arm one end is provided with a plurality of magnetic blocks which are circular in shape, the arm can be adsorbed on the fuselage interface through the magnetic blocks.

[0020] Among them, the plug is T-shaped for combining with the socket.

[0021] Working principle: in the working process of unmanned aerial vehicle, the paddle often needs to be replaced due to wear, aging, damage, design optimization, balance problem, material upgrading and adaptation to different tasks of respective scenes; when the paddle of unmanned aerial vehicle is damaged and needs to be replaced, the worker inserts his hand into the gap between the paddle and the arm, presses the button on the locking device with the index finger and the thumb for triggering the lock to open, at this time, the button drives the push rod to move, the push rod moves forward under the action of the thrust and pushes the connecting rod, the connecting rod is connected with the locking block, the locking block moves backward and leaves the locking hole on the socket, at this time, the locking spring is tightened, and due to the limitation of the limiting block, the fixing block is fixed on the limiting block and cannot move excessively to cause the failure of the device; at this time, the locking block is separated from the locking hole, the plug is popped up under the action of the elastic force of the connecting spring on the socket, the worker holds the damaged paddle with the other hand and takes it out; at this time, the worker can dismount the damaged paddle without tools, realizing the quick dismounting of the paddle.

[0022] When a new unmanned aerial vehicle paddle needs to be installed, only the plug at the lower part of the intact paddle is aligned with the socket, the plug is pushed downward to press the connecting spring, at this time, when the plug touches the locking block of the locking structure, the locking block moves backward under the action of the thrust, due to the action of the locking spring and the fixing block, the locking block leans on the fixing block under the action of the elastic force of the locking spring; at this time, the plug is pushed downward again, when the worker hears the sound of spring rebounding, it is known that the locking block has been inserted into the fixing hole, at this time, the new paddle is installed, the whole process does not need any tool, and a single person can complete the operation within a few seconds.

[0023] The arm will be affected by various forces during flight, such as lift, drag, and vibration during flight, which may cause the arm to wear or be damaged, so the arm of the unmanned aerial vehicle often needs to be replaced; when a new arm needs to be installed, a plurality of circular magnetic blocks are installed around the arm, and a magnetic adsorption assembly (not shown in the figure) is installed inside the fuselage interface, the arm is close to the fuselage interface, and the magnetic adsorption assembly automatically attracts the arm to accurately align; after alignment, the arm is gently pushed forward, and the magnetic blocks and the magnetic adsorption assembly are firmly combined to ensure stable connection.

[0024] When the arm needs to be disassembled, the operator only needs to overcome the magnetic adsorption force and pull the arm outward along the axial direction; during disassembly, the magnetic adsorption force provides a certain resistance, but only a small force is needed to complete the separation; the disassembly process is quick and convenient, and is especially suitable for quick repair and replacement in emergency situations.

[0025] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or basic characteristics of the present application.
