[0037] The present application does not specifically limit the shape of the top surface 110a of the rotor top cover 110. In a possible embodiment, the top surface 110a of the rotor top cover 110 may be circular.

The present application does not specifically limit the shape of the first mounting hole 1101. Exemplarily, the shape of the first mounting hole 1101 can be circular, or elliptical, or rectangular, or square, or trapezoidal.

[0039] The present application does not specifically limit the height of the first assembly part 112 protruding relative to the top surface 110a of the rotor top cover 110. The first assembly part 112 is fixedly connected to the rotor top cover 110.

Among them, the plane inclined surface can be understood as a plane inclined relative to the top surface 110a of the rotor top cover 110. The curved inclined surface can be understood as a curved surface of the top surface 110a inclined relative to the rotor top cover 110. In a possible embodiment, the distance between the first inclined surface 1120 and the top surface 110a of the rotor top cover 110 can gradually increase in the clockwise circumferential direction of the rotor top cover 110. Of course, in other possible embodiments, the distance between the first inclined surface 1120 and the top surface 110a of the rotor top cover 110 can also gradually decrease in the clockwise circumferential direction of the rotor top cover 110.

[0041] It can be understood that the second assembly part 113 can be retracted relative to the rotor cover 110. The second assembly part 113 is retracted relative to the rotor cover 110 in the first state, and is extended relative to the rotor cover 110 in the second state. Optionally, the second assembly part 113 is flush with the top surface 110a of the rotor cover 110 in the first state, or the second assembly part 113 is recessed relative to the top surface 110a of the rotor cover 110 in the first state. The second assembly part 113 is completely protruded from the top surface 110a of the rotor cover 110 in the second state, or the second assembly part 113 is partially protruded from the top surface 110a of the rotor cover 110 in the second state.

[0042] Please refer to Figure 4 and Figure 5 , Figure 4 for Figure 1 The schematic diagram of a part of the structure of the blade module 20 in the UAV power device 100 is shown. Figure 5 for Figure 4 A schematic diagram of the structure of the third assembly part 202 in the blade module 20 shown. The blade module 20 includes a blade assembly 201 and a third assembly part 202. The third assembly part 202 is fixedly connected to the blade assembly 201. The third assembly part 202 includes a first assembly part 220 and at least one second assembly part 221, the first assembly part 220 is formed with at least one assembly notch 220a, the second assembly part 221 is convexly arranged on the outer peripheral surface of the first assembly part 220, and the second assembly part 221 has a second inclined surface 221a.

[0043] The blade assembly 201 includes at least one blade. The blade includes but is not limited to a conventional blade, a folding blade, a variable blade, or a rotor blade. The material of the blade includes but is not limited to carbon fiber, glass fiber, or plastic.

[0044] The third assembly part 202 and the blade assembly 201 may be fixedly connected in a detachable manner or in a non-detachable manner.

[0045] The present application does not make any specific limitation on the number of the second assembly parts 221 included in the third assembly part 202. Specifically, the number of the second assembly parts 221 can be one or more. In a possible embodiment, the number of the second assembly parts 221 can be the same as the number of the first assembly parts 112. The present application does not make any specific limitation on the number of assembly notches 220a. Specifically, the number of assembly notches 220a can be one or more. In a possible embodiment, the number of assembly notches 220a can be the same as the number of the second assembly parts 113.

[0046] The first assembly portion 220 may be in a hollow cylindrical shape. The bottom end of the first assembly portion 220 is closer to the motor module 10 than the top end of the first assembly portion 220. In the embodiment of the present application, the assembly notch 220a is located at the bottom end of the first assembly portion 220, and the second assembly portion 221 is provided at the bottom end of the first assembly portion 220.

[0047] The second inclined surface 221a can be a plane inclined surface or a curved inclined surface. Optionally, when the first inclined surface 1120 is a plane inclined surface, the second inclined surface 221a is a plane inclined surface; when the first inclined surface 1120 is a curved inclined surface, the second inclined surface 221a is a curved inclined surface. It can be understood that the thickness of the second assembly portion 221 is uneven. In a possible embodiment, the thickness of the second assembly portion 221 can gradually increase along the extension direction from the first end to the second end of the second assembly portion 221.

[0048] During the assembly of the motor module 10 and the blade module 20 , the third assembly part 202 is used to contact the top surface 110a of the rotor cover 110 and rotate relative to the rotor cover 110 , and the second assembly part 113 is used to be in the first state.

[0049] In the embodiment where the distance between the first inclined surface 1120 and the rotor cover 110 gradually increases along the clockwise circumferential direction of the rotor cover 110, the third assembly part 202 can rotate counterclockwise relative to the rotor cover 110 during the assembly of the motor module 10 and the blade module 20. In the embodiment where the distance between the first inclined surface 1120 and the rotor cover 110 gradually decreases along the clockwise circumferential direction of the rotor cover 110, the third assembly part 202 can rotate clockwise relative to the rotor cover 110 during the assembly of the motor module 10 and the blade module 20.

[0050] During the assembly process of the motor module 10 and the blade module 20, the second assembly part 113 can be in the first state under the squeezing action of the third assembly part 202, or can be in the first state under the action of other forces (for example, artificially applied force, or the driving force of the driving motor, etc.).

[0051] Please refer to Figures 2 to 6 , Figure 6 for Figure 1 A partial enlarged schematic diagram of the A region in the UAV power device 100 is shown. When the motor module 10 and the blade module 20 are assembled, the second assembly portion 221 is received in the receiving space 114, and the second inclined surface 221a contacts the first inclined surface 1120, the second assembly part 113 is in the second state, and at least part of the second assembly part 113 protruding relative to the top surface 110a of the rotor top cover 110 is received in the assembly notch 220a, and forms a limit fit with the assembly notch 220a.

[0052] It can be understood that when the motor module 10 and the blade module 20 are assembled, the second assembly portion 221 is sandwiched between the first inclined surface 1120 and the top surface 110a of the rotor top cover 110. For example, in the clockwise circumferential direction of the rotor top cover 110, the distance between the first inclined surface 1120 and the top surface 110a of the rotor top cover 110 gradually increases, and in the extending direction from the first end to the second end of the second assembly portion 221, the thickness of the second assembly portion 221 gradually increases. When the motor module 10 and the blade module 20 are assembled, the first end of the second assembly portion 221 abuts between the first end of the first inclined surface 1120 and the top surface 110a of the rotor top cover 110, and the second end of the second assembly portion 221 abuts between the first end of the first inclined surface 1120 and the top surface 110a of the rotor top cover 110. The extension direction from the first end of the first inclined surface 1120 to the second end of the first inclined surface 1120 is along the clockwise circumferential direction of the rotor top cover 110. When the motor module 10 and the blade module 20 are assembled, the second assembly part 113 and the assembly notch 220a form a limit along the circumferential direction of the rotor top cover 110.

[0053] The UAV power device 100 and the UAV provided in the present application include a motor module 10 and a blade module 20. During the assembly process of the motor module 10 and the blade module 20, the third assembly part 202 of the blade module 20 is used to contact the top surface 110a of the rotor cover 110 of the motor module 10 and rotate relative to the rotor cover 110. The second assembly part 113 of the motor module 10 is used to be in the first state. Therefore, the blade module 20 is placed on the rotor cover 110. By rotating the third assembly part 202 relative to the rotor cover 110, the motor module 10 and During the assembly of the blade module 20, since the second assembly part 113 of the motor module 10 is in the first state, that is, the second assembly part 113 does not protrude from the top surface 110a of the rotor top cover 110, the second assembly part 113 will not interfere with the rotation of the third assembly part 202, so that the motor module 10 and the blade module 20 can be easily assembled. In addition, when the motor module 10 and the blade module 20 are assembled, the second assembly portion 221 of the third assembly part 202 is accommodated in the storage space formed between the rotor top cover 110 and the first assembly part 112 of the motor module 10. In the accommodation space 114, the second inclined surface 221a of the second assembly portion 221 contacts the first inclined surface 1120 of the first assembly member 112, and the second assembly member 113 is in the second state. At least part of the second assembly member 113 protruding relative to the top surface 110a of the rotor top cover 110 is accommodated in the assembly notch 220a of the third assembly member 202, and forms a limit fit with the assembly notch 220a. Therefore, a limit can be formed between the first inclined surface 1120 of the motor module 10 and the second inclined surface 221a of the blade module 20, which is conducive to improving the motor module 10 and the blade module The tensile effect of 20 after assembly is completed can prevent the motor module 10 and the blade module 20 from sliding relative to each other, and a limiting fit is also formed between the second assembly part 113 and the assembly notch 220a, which is beneficial to improving the anti-torsion effect of the motor module 10 and the blade module 20 after assembly is completed, and can prevent the motor module 10 and the blade module 20 from rotating relative to each other, thereby ensuring the assembly reliability between the motor module 10 and the blade module 20, and convenient disassembly of the motor module 10 and the blade module 20 can be achieved by rotating the third assembly part 202 in the opposite direction relative to the rotor top cover 110.

[0054] In a possible embodiment, the rotor assembly 101 further includes at least one elastic member. The elastic member is connected to the second assembly member 113. During the assembly process of the motor module 10 and the blade module 20, the first assembly portion 220 squeezes the second assembly member 113 to compress the elastic member. When the elastic member is compressed, the second assembly member 113 is driven to switch from the second state to the first state. When the motor module 10 and the blade module 20 are assembled, the elastic member is restored to drive the second assembly member 113 to switch from the first state to the second state.

[0055] The elastic member includes but is not limited to a spring, or a bellows, etc. In the embodiment of the present application, the elastic member is taken as an example of a spring. The elastic member connecting the second assembly part 113 includes but is not limited to the elastic member being fixedly connected to the second assembly part 113, or the elastic member abuts against one side of the second assembly part 113, or the second assembly part 113 may be formed with a first connecting column, and the elastic member may be sleeved on the first connecting column. The elastic member is arranged on the side of the second assembly part 113 away from the third assembly part 202.

[0056] In this embodiment, an elastic member is provided so that during the assembly of the motor module 10 and the blade module 20, the elastic member can drive the second assembly member 113 to retract relative to the top surface 110a of the rotor top cover 110; when the motor module 10 and the blade module 20 are assembled, the elastic member can drive the second assembly member 113 to extend relative to the top surface 110a of the rotor top cover 110, thereby realizing that the second assembly member 113 has a first state and a second state, and the second assembly member 113 can switch between the first state and the second state, and the state switching of the second assembly member 113 is more automated and has a simple structure, thereby avoiding the need to additionally provide a drive motor to drive the second assembly member 113 to extend and retract.

[0057] In a possible embodiment, the rotor assembly 101 includes a plurality of first assembly parts 112 and a plurality of second assembly parts 113, wherein the plurality of first assembly parts 112 are arranged at intervals along the circumference of the rotor cover 110, and the plurality of second assembly parts 113 are arranged at intervals along the circumference of the rotor cover 110. The number of the second assembly portions 221 is the same as the number of the first assembly parts 112, and the number of the assembly notches 220a is the same as the number of the second assembly parts 113.

[0058] Exemplarily, the number of first assemblies 112 may be two, three, four, or five. The number of second assemblies 113 may be two, three, four, or five. In the embodiment of the present application, two first assemblies 112 and two second assemblies 113 are taken as an example. Optionally, at least one second assembly 113 is arranged between two adjacent first assemblies 112, and / or at least one first assembly 112 is arranged between two adjacent second assemblies 113. In the embodiment of the present application, the first assemblies 112 and the second assemblies 113 are alternately arranged along the circumferential direction of the rotor top cover 110 as an example.
