Technical Field
[0001] The present application relates to the technical field of unmanned aerial vehicles, and in particular to a propeller structure of an unmanned aerial vehicle that can be quickly disassembled and assembled. Background Art
[0002] With the rapid development of drone technology, drones have been widely used in many fields such as aerial photography, agriculture, and rescue. Among them, drone blades are key components, and their performance and ease of maintenance directly affect the user experience of drones. Traditional drone blades are usually fixed with screws or other permanent connections, which makes the disassembly and assembly process cumbersome and time-consuming when the blades are damaged or need maintenance.
[0003] Although the existing UAV propeller connection methods meet flight requirements to a certain extent, they still have obvious shortcomings in terms of quick disassembly and assembly. For example, the screw connection method requires the use of tools during the disassembly and assembly process, and the operation is complicated; while the permanent connection method makes it difficult to replace the propeller blade once it is damaged. These problems limit the efficient maintenance and flight safety of UAVs. Utility Model Content

As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "above", "the" and "this" are intended to also include plural expressions, unless there is a clear indication to the contrary in the context. It should also be understood that the term "and / or" used in the present application refers to and includes any or all possible combinations of one or more listed items.
[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 , is a rapidly disassembled drone blade structure disclosed in an embodiment of the present application, comprising: a blade body 10, a base assembly 20 and a cover assembly 30, wherein the blade body 10 is located between the base assembly 20 and the cover assembly 30;
[0037] See also Figure 2 The blade body 10 is provided with a plug hole 11 located in the middle of the blade body 10. One end of the base assembly 20 is provided with a connecting column 21 for penetrating the plug hole 11, and the connecting column 21 is provided with a first external thread 211.
[0038] The cover assembly 30 includes a locking handle 31, and an internal thread (not marked in the figure) adapted to the first external thread 211 is provided at one end of the locking handle 31. During assembly, the connecting column 21 of the base assembly 20 is first inserted through the plug hole 11, so that the user can manually screw the locking handle 31 to connect to the connecting column 21 based on the rotational connection between the internal thread and the first external thread 211, thereby pressing the blade body 10 to achieve assembly of the blade body 10, the base assembly 20 and the cover assembly 30.
[0039] See also Figure 2 and Figure 3 The seat assembly includes a driving member 22, a base 23, a first fixing member 24 and a second fixing member 26. The connecting column 21 is located at the end of the base 23 away from the driving member 22, so as to penetrate the plug-in member and connect the locking handle 31. The driving member 22 is a motor, and the output end of the driving member 22, i.e., the rotating end, and the base 23 are correspondingly provided with a first fixing hole 25, so that the first fixing member 24 penetrates the first fixing hole 25 to achieve a stable connection between the driving member 22 and the base 23.
[0040] See also Figure 2 A second fixing hole 12 is provided on the blade body 10 and the base 23 corresponding to the second fixing piece 26. The second fixing piece 26 and the second fixing hole 12 are correspondingly set to four and are evenly arranged, so that the connection between the blade body 10 and the base 23 can be more uniform and stable, and the problems of stress concentration and local looseness can be effectively avoided.
[0041] Thus, the blade body 10 can be sleeved on the second fixing member 26 through the second fixing hole 12. During assembly, the base assembly 20 first limits the blade body 10 through the second fixing member 26, so as to facilitate the locking handle 31 to connect the connecting column 21, while ensuring the structural stability of the driving member 22 and the blade body 10.
[0042] The cover plate assembly 30 further includes a pressing plate 32 , which is used to be sleeved on the locking handle 31 and is located between the locking handle 31 and the blade body 10 .
[0043] Among them, a through hole is set in the middle of the pressure plate 32, or an internal spiral is set based on the thickness of the pressure plate 32, and a corresponding second external thread 311 is set on the outer side of one end of the locking handle 31. The pressure plate 32 can be screwed on the locking handle 31 in a rotational manner, so that when the locking handle 31 is screwed by external force, the pressure plate 32 synchronously presses the blade body 10, thereby increasing the clamping force of the locking handle 31 on the blade body 10, making the overall connection more secure.
[0044] The pressing plate 32 is further provided with limiting holes 321 , which correspond to the second fixing members 26 , and are each provided with four limiting holes, for example.
[0045] The limiting hole 321 cooperates with the second fixing member 26 to ensure accurate positioning of the pressing plate 32 during the locking process, and prevent the pressing plate 32 from being offset or rotated, thereby enhancing the stability of the blade structure.
[0046] In addition, the cover plate assembly 30 further includes an anti-loosening member 33 which is sleeved on one end of the locking handle 31 and is located between the locking handle 31 and the pressing plate 32 .
[0047] Among them, a through hole is provided in the middle of the anti-loosening part 33, and anti-slip grooves are provided on the two side surfaces relative to the locking handle 31 and the pressure plate 32, so as to increase the friction resistance between the side surfaces, so as to effectively prevent the locking handle 31 from loosening after long-term use, and further improve the safety and reliability of the blade structure.
[0048] In summary, the embodiment of the present application discloses a rapidly disassembled drone blade structure, which can be firmly fixed between the base assembly 20 and the cover assembly 30 by manually twisting the locking handle 31 so that the internal thread thereof is tightly matched with the first external thread 211 on the connecting column 21. This connection method is simple and efficient, does not require the use of additional tools, greatly improves the efficiency of disassembly and assembly of the blade, and further improves the maintenance efficiency, and can ensure safety and stability during flight.
