[0002] With the rapid development of drone technology, drone blades, as one of its core components, have a crucial impact on the flight performance and stability of drones. Existing drone blade structures mostly use complex connection methods, which not only increases manufacturing costs, but also reduces assembly efficiency and may also affect flight stability.

[0003] At present, although some drone propeller structures on the market use some quick connection methods, they are often not stable and are prone to loosening or even falling off after long-term flight, seriously affecting the flight safety of the drone. Therefore, how to ensure the stability of the propeller structure while pursuing simple structure and convenient assembly is a major problem facing designers. Utility Model Content

[0004] In order to solve or partially solve the problems existing in the above-mentioned related technologies, the present application provides a UAV blade structure, which can not only simplify the assembly process, but also greatly improve the stability of the structure, providing strong support for the safe flight of the UAV.

[0007] By adopting the above technical solution, the blade body can be firmly fixed between the base assembly and the cover assembly by manually twisting the left-turn locking handle and the right-turn locking handle to make the internal thread and the external thread on the connecting column tightly match. Therefore, the embodiment of the present application can not only simplify the assembly process, but also greatly improve the stability of the structure, providing strong support for the safe flight of the drone.

[0008] Optionally, the base assembly includes: a driving member, located at one end of the connecting column away from the blade body; a base, connected to the output end of the driving member, located between the driving member and the blade body, and integrally arranged with the connecting column.

[0034] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0035] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1 and Figure 2 , is a UAV blade structure disclosed in an embodiment of the present application, including: a blade body 10, a base assembly 20 and a cover assembly 30, and the blade body 10 is located between the base assembly 20 and the cover assembly 30.

[0037] Among them, a plug hole 11 is provided in the middle of the blade body 10 for the base assembly 20 to penetrate to connect the cover assembly 30. A connecting column 21 is provided at one end of the base assembly 20, which penetrates the blade body 10 through the plug hole 11 to connect the cover assembly 30, wherein the portion connected to the cover assembly 30 is sequentially provided with a left external thread 211 and a right external thread 212. The cover assembly 30 includes a left-handed locking handle 31 and a right-handed locking handle 32, wherein the left-handed locking handle 31 is provided with a left internal thread 311 corresponding to the left external thread 211, and the right-handed locking handle 32 is provided with a right internal thread 321 corresponding to the right external thread 212.

[0038] It is worth mentioning here that the rotation directions of the left external thread 211 and the right external thread 212 are opposite, and the corresponding left-hand locking handle 31 and right-hand locking handle 32 rotate in opposite directions on the connecting column 21 to strengthen the fixation of the blade body 10, thereby greatly improving the stability of the overall structure.

[0039] In addition, two rotation angles are provided on the outside of the left-hand locking handle 31, and four rotation angles are provided on the outside of the right-hand locking handle 32, so that the operator can easily rotate the rotation angles manually and easily screw the left-hand locking handle 31 and the right-hand locking handle 32 to the connecting column 21 to achieve a labor-saving effect. Here, the number of rotation angles on the left-hand locking handle 31 and the right-hand locking handle 32 is not limited, as long as the same labor-saving effect can be achieved.

[0040] During assembly, the operator manually rotates the rotation angle of the left-hand locking handle 31 and the rotation angle of the right-hand locking handle 32 in sequence, so that the left-hand locking handle 31 is adapted to the left external thread 211 via the left internal thread 311, and the right-hand locking handle 32 is adapted to the right external thread 212 via the right internal thread 321, so that they are screwed together and fixed on the connecting column 21 to press the blade body 10, thereby achieving a secure assembly of the blade body 10, the base assembly 20 and the cover assembly 30.

[0041] Specifically, the base assembly 20 includes a driving member 22 and a base 23. The driving member 22 is located at one end of the connecting column 21 away from the blade body 10. The base 23 is connected to the output end of the driving member 22, that is, the rotating end, and is located between the driving member 22 and the blade body 10, and is integrally provided with the connecting column 21. In this way, the connection stability between the base 23 and the driving member 22 can be ensured, and the assembly process is also convenient.

[0042] See also Figure 3 and Figure 4 A first fixing hole 231 , a first fixing member 232 and a second fixing member 233 are provided on the base 23 . The base 23 is connected to the output end of the driving member 22 via the first fixing member 232 penetrating the first fixing hole 231 , and the second fixing member 233 is arranged around the connecting column 21 .

[0043] Among them, the base 23 can be tightly connected to the output end of the driving member 22 by the first fixing member 232 penetrating the first fixing hole 231, thereby ensuring the stability and reliability of the entire base assembly 20. The second fixing member 233 is provided in plurality, and a plurality of second fixing holes 12 are provided on the blade body 10 corresponding to the plurality of second fixing members 233. In this way, the connection between the blade body 10 and the base 23 can be further strengthened, greatly improving the stability of the overall structure.

[0044] See also Figure 2In the present embodiment, the second fixing member 233 and the second fixing hole 12 are correspondingly set to 4, which can make the connection between the blade body 10 and the base 23 more uniform and stable, so as to effectively avoid the problems of stress concentration and local looseness.

[0045] See also Figure 2 and Figure 4 The cover assembly 30 also includes a pressing plate 33, which is sleeved on the connecting column 21 and located between the left-hand locking handle 31 and the blade body 10, and the pressing plate 33 is also provided with a second fixing hole 12 corresponding to the second fixing member 233.

[0046] Among them, during assembly, the second fixing member 233 passes through the blade body 10 and the pressure plate 33 in sequence through the second fixing hole 12, so that the base 23, the blade body 10 and the pressure plate 33 can rotate synchronously under the drive of the driving member 22. At the same time, the setting of the pressure plate 33 can further increase the clamping force of the left-turn locking handle 31 and the right-turn locking handle 32 on the blade body 10, making the connection more secure.

[0047] In summary, the drone blade structure disclosed in the embodiment of the present application can securely fix the blade body 10 between the base assembly 20 and the cover assembly 30 by manually twisting the left-hand locking handle 31 and the right-hand locking handle 32 to make the internal thread of the blade tightly fit with the external thread of the connecting column 21. Therefore, the embodiment of the present application can not only simplify the assembly process, but also greatly improve the stability of the structure, providing strong support for the safe flight of the drone.
