[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0027] This embodiment provides a drone, which includes a drone propeller blade quick-release structure as shown in Figures 1-7 A drone propeller blade quick-release structure includes a propeller blade 1 and a base block 2 located below the propeller blade 1. The base block 2 is installed on the body of the drone. The base block 2 is provided with a disassembly and assembly component 3 for connecting or disconnecting the propeller blade 1 from the base block 2. The disassembly and assembly component 3 includes a limiting member 31 that can move to a locking position to fix the propeller blade 1 and can move to an unlocking position to unlock the propeller blade 1. The disassembly and assembly component 3 further includes an elastic member 34 that can keep the limiting member 31 in the locking position. Through the disassembly and assembly component, the propeller can be replaced without tools, enabling the user to avoid using tools for disassembly when replacing the propeller and improving the convenience of using the drone.

[0028] In some embodiments: The propeller blade 1 includes a connection block 11 for detachably mating with the base block 2. The connection block 11 is provided with a limiting area 12 for mating and clamping with the limiting member 31. The disassembly and assembly component 3 further includes a movable member 32 located on the base block 2 for driving the limiting member 31 to move. The base block 2 is provided with a receiving groove 33 for mating with the movable member 32. The limiting member 31 is inserted through the movable member 32. The base block 2 is provided with a guiding groove 35 for mating with the limiting member 31. The limiting member 31 passes through the guiding groove 35 and protrudes from the surface of the base block 2. The receiving groove 33 forms a through-opening 37 at the end face of the base block 2. The pressing end of the movable member 32 passes through the through-opening 37 and protrudes from the end face of the base block 2. Hooks 14 are provided at both ends of the lower side surface of the connection block 11. The recessed portion of the hook 14 forms the limiting area 12. The disassembly and assembly components 3 corresponding to the hooks 14 are provided on both sides of the base block 2. When the propeller blade 1 needs to be disassembled, the movable member 32 is pressed towards the base block 2. The movable member 32 starts to move. When the movable member 32 moves, it will drive the limiting member 31 to move together, causing the limiting member 31 to start moving from the locked position to the unlocked position. When the limiting member 31 moves, it will disengage from the limiting area 12, so that it can leave the locked position and release the limitation on the connection block 11, allowing the user to disassemble the propeller blade 1. When installing, the connection block 11 is pressed so that the position of the limiting area 12 coincides with the locked position. At this time, the pressing on the movable member 32 is released, and the elastic member 34 pushes the movable member 32 back to its original position, causing the limiting member 31 to return to the locked position. When the limiting member 31 returns to the locked position, it will enter the inside of the limiting area 12 to limit and fix the connection block 11, achieving the purpose of fixing the propeller blade.

[0029] In some embodiments: A locking member 13 is provided above the propeller blade 1. The locking member 13 is used to lock the propeller blade 1 on the connection block 11. A positioning hole 21 is provided above the base block 2. A positioning rod 22 for mating with the positioning hole 21 is provided below the connection block 11. The locking member 13 and the propeller blade 1 are fixedly installed by screws, so that the locking member 13 can fix the propeller blade 1 on the connection block 11. Because there is a positioning rod 22 below the connection block 11, when the connection block 11 is placed, the cooperation between the positioning rod 22 and the positioning hole 21 can ensure that when the connection block 11 is placed on the base block 2, the connection between the connection block 11 and the base block 2 can form a foolproof design, ensuring that the connection block 11 can drive the propeller blade 1 to be installed normally.

[0030] In some embodiments: a threaded hole is provided on one side of the movable member 32, and a screw 36 is provided inside the threaded hole, which is connected by screw engagement to press the limiting member 31 inside the movable member 32. When the fixation of the limiting member 31 is to be released, the screw 36 is rotated in the reverse direction. After the screw 36 rotates in the reverse direction, it will gradually move away from the limiting member 31, so that the screw 36 releases the pressing on the limiting member 31, allowing the limiting member 31 to move inside the movable member 32, so as to take out the limiting member 31. When the limiting member 31 is to be pressed and fixed, the screw 36 is rotated in the forward direction, so that the screw 36 presses the limiting member 31 tightly to ensure that the limiting member 31 does not shift.

[0031] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
