Description

Technical Field

[0001] This application relates to the field of flight equipment technology, specifically to a flapping-wing aircraft. Background Technology

[0002] The stealth capabilities of ornithopter aircraft compared to fixed-wing and rotary-wing aircraft have led to their widespread use.

[0003] The flapping-wing aircraft mainly consists of the flapping-wing aircraft body, flapping wings, and tail fin. When in use, the flapping wings swing up and down along the flapping-wing aircraft body to achieve flight. The flapping-wing aircraft is relatively large, with the largest reaching more than 30 meters. At least two connecting structures are required between the flapping wings and the flapping-wing aircraft body to ensure structural reliability. The more connecting structures there are, the more difficult it is to assemble the flapping wings and the flapping-wing aircraft body. However, if it is assembled before leaving the factory and then shipped, the large size of the flapping-wing aircraft will undoubtedly increase the difficulty of packaging and transportation. Utility Model Content

[0004] The purpose of this application is to at least solve the technical problems of existing flapping-wing aircraft, such as the complex connection structure between the flapping wing and the flapping-wing fuselage, which requires certain professional knowledge and greatly increases the difficulty of assembly, maintenance, and portability. This purpose is achieved through the following technical solution:

[0005] This application provides a flapping-wing aircraft, including a fuselage, flapping wings, a first disassembly assembly, and a second disassembly assembly. The flapping wings are disposed on both sides of the fuselage. The first disassembly assembly is used for quick-connect connection between the fuselage and the flapping wings at a first position on the fuselage. The second disassembly assembly is used for quick-connect connection between the fuselage and the flapping wings at a second position on the fuselage. The first position and the second position are arranged along the length direction of the fuselage.

[0006] In this embodiment, the flapping-wing aircraft proposed in this application uses a first disassembly and assembly component and a second disassembly and assembly component to quickly connect the flapping wing and the fuselage at the first and second positions, respectively. This ensures the structural connection reliability between the flapping wing and the fuselage, and enables quick disassembly and assembly between the flapping wing and the fuselage, improving disassembly and assembly efficiency, reducing disassembly and assembly difficulty, and facilitating repair and replacement when the flapping wing and / or the fuselage are damaged. At the same time, by modularizing the flapping-wing aircraft, it is convenient to package and transport the flapping-wing aircraft, reducing packaging and transportation costs and difficulties, and facilitating the commercial promotion of the flapping-wing aircraft.

[0007] In some embodiments, the first disassembly and assembly assembly includes a first disassembly and assembly connector and a first plug connector. The first disassembly and assembly connector is disposed at a first position of the body and is capable of swinging up and down relative to the body. The first disassembly and assembly connector is provided with a plug hole. The first plug connector is disposed at a position of the flapping wing corresponding to the first position. The first plug connector has a first state of being plugged into and fixed in the plug hole and a second state of being disengaged from the plug hole.

[0008] In some embodiments, the first connector includes a plug shaft and a first connecting rod. The plug shaft is used to insert into the plug hole of the first detachable connector. One end of the first connecting rod is connected to the plug shaft, and the other end of the first connecting rod is connected to the flapping wing.

[0009] In some embodiments, the first connector further includes a first connecting portion disposed between the insert shaft and the first connecting rod, wherein the first connecting portion and the first disassembly connector abut against each other when the insert shaft is fully inserted into the insertion hole of the first disassembly connector.

[0010] In some embodiments, the first disassembly and assembly component further includes a first disassembly and assembly latch, which engages and locks the first connector and the first disassembly and assembly connector when the first connector is in the first state.

[0011] In some embodiments, the first disassembly / removal clip is hinged to the first connector. When the first connector is in a first state, the first disassembly / removal clip is engaged and fixed with the first disassembly / removal connector. When the first connector needs to switch from the first state to the second state, the first disassembly / removal clip is separated from the first disassembly / removal connector.

[0012] In some embodiments, the first disassembly connector has a snap-fit ​​protrusion on the side away from the machine body, the first disassembly head includes a head body, the head body is hinged to the first connector, and a buckle is provided at one end of the head body extending toward the first disassembly connector, the buckle being configured to snap onto or disengage from the snap-fit ​​protrusion.

[0013] In some embodiments, the first snap-fit ​​clip further includes a first torsion spring, which is disposed between the clip body and the first connecting rod of the first connector, or the first torsion spring is disposed between the clip body and the insertion shaft of the first connector, and the first torsion spring applies an elastic force to the snap-fit ​​clip to engage with the snap-fit ​​protrusion.

[0014] In some embodiments, the second disassembly assembly includes a connector and a second plug. The connector is disposed at a second position on the body and has a plug groove. The second plug is disposed at a position on the flapping wing corresponding to the second position. The second plug has a third state in which it is inserted into the plug groove and can rotate relative to the plug groove, and the second plug also has a fourth state in which it is disengaged from the plug groove.

[0015] In some embodiments, the second connector includes a flapping wing pivot and a second connecting rod. The flapping wing pivot is rotatably disposed in the insertion slot of the connector. One end of the second connecting rod is connected to the flapping wing, and the other end of the second connecting rod is connected to the flapping wing pivot.

[0016] In some embodiments, the second disassembly assembly further includes a second disassembly clip, which engages with the notch of the connector slot when the second connector is in the third state.

[0017] In some embodiments, the second disassembly / removal clip is rotatably mounted on the connector. When the second connector is in the third state, the second disassembly / removal clip rotates and engages with the notch of the connector groove. When the second connector needs to switch from the third state to the fourth state, the second disassembly / removal clip rotates and disengages from the notch of the connector groove.

[0018] In some embodiments, the second mounting / dismounting clip includes a second connecting portion and a snap-fit ​​portion. The second connecting portion is rotatably connected to the connecting seat, and the snap-fit ​​portion and the second connecting portion are fixedly connected.

[0034] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0035] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The terms “comprising,” “including,” and “having” are inclusive and therefore indicate the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0036] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Furthermore, in the description of this application, unless otherwise expressly specified and limited, the terms "set up" and "connected" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a direct connection or an indirect connection via an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "above," "below," "inner," "outer," "end," "side," etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation, in addition to those depicted in the figure. For example, if the mechanism in the figure is flipped, then an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0038] The connection structure between the flapping wing 20 and the fuselage 10 of the flapping wing aircraft in the relevant technology is complex. Disassembly and assembly require professional knowledge and are difficult to assemble. It is also not conducive to the replacement and maintenance of parts. If the flapping wing aircraft is assembled and then packaged for transportation, the packaging and transportation difficulties will be increased, which is not conducive to the commercial promotion of the flapping wing aircraft.

[0039] To address the aforementioned issues, this application provides a first disassembly / assembly component 30 and a second disassembly / assembly component 40 to quickly connect the flapping wing 20 and the fuselage 10 at their first and second positions. This enables rapid installation and disassembly of the flapping wing 20 and the fuselage 10, reducing the difficulty of disassembling and assembling the flapping wing aircraft, facilitating the maintenance and replacement of the flapping wing 20 and the fuselage 10, and enabling modular packaging and transportation of the flapping wing aircraft, reducing packaging and transportation costs and difficulties, and promoting the commercialization of the flapping wing aircraft.

[0040] Furthermore, the terms "upper" and "lower" used in the embodiments of this application are based on the normal flight attitude of the flapping-wing aircraft, or on the normal parking attitude of the flapping-wing aircraft, such as... Figure 2 As shown, the up and down direction is indicated by the Y-arrow. The side of the flapping-wing aircraft facing the ground is "down," and the side facing away from the ground is "up." The length direction of the fuselage 10 is consistent with the length direction of the flapping-wing aircraft. Figure 2 The direction indicated by the X arrow, "first position" refers to the position near the nose of the flapping-wing aircraft, and "second position" refers to the position near the tail of the flapping-wing aircraft.

[0041] like Figures 1 to 7 As shown, this application provides a flapping-wing aircraft, including a body 10, flapping wings 20, a first disassembly assembly 30, and a second disassembly assembly 40. The flapping wings 20 are disposed on both sides of the body 10. The first disassembly assembly 30 is used for quick-connect connection of the body 10 and the flapping wings 20 at a first position 11 of the body 10. The second disassembly assembly 40 is used for quick-connect connection of the body 10 and the flapping wings 20 at a second position 12 of the body 10. The first position 11 and the second position 12 are arranged along the length direction of the body 10.

[0042] In this embodiment, the flapping-wing aircraft proposed in this application has a quick-connect connection between the flapping wing 20 and the fuselage 10 at the first position 11 and the second position 12 via a first disassembly / assembly component 30 and a second disassembly / assembly component 40. This ensures the structural connection reliability between the flapping wing 20 and the fuselage 10, and enables quick disassembly / assembly between the flapping wing 20 and the fuselage 10, improving disassembly / assembly efficiency and reducing disassembly / assembly difficulty. It also facilitates repair and replacement when the flapping wing 20 and / or the fuselage 10 are damaged. At the same time, by modularizing the flapping-wing aircraft, it is convenient to package and transport the aircraft, reducing packaging and transportation costs and difficulties, which is conducive to the commercial promotion of the flapping-wing aircraft.

[0043] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the first disassembly and assembly assembly 30 includes a first disassembly and assembly connector 31 and a first plug connector 32. The first disassembly and assembly connector 31 is disposed at a first position 11 of the body 10 and the first disassembly and assembly connector 31 is capable of swinging up and down relative to the body 10. The first disassembly and assembly connector 31 is provided with a plug hole 311. The first plug connector 32 is disposed at a position of the flapping wing 20 corresponding to the first position 11. The first plug connector 32 has a first state of being plugged into and fixed in the plug hole 311 and a second state of being disengaged from the plug hole 311.

[0044] With the above settings, when the first connector 32 is in the first state, the first connector 32 is inserted and fixed in the insertion hole 311 of the first disassembly and assembly connector 31, thereby connecting the flapping wing 20 and the fuselage 10 at the first position 11. The first disassembly and assembly connector 31 can swing up and down relative to the fuselage 10, thereby driving the first connector 32 and the flapping wing 20 to swing up and down together, ensuring the normal flight of the flapping wing aircraft. When the first connector 32 is in the second state, the first connector 32 is disengaged from the insertion hole 311 of the first disassembly and assembly connector 31, thereby separating the flapping wing 20 and the fuselage 10. Therefore, the matching setting of the first connector 32 and the insertion hole 311 realizes the quick installation and disassembly between the flapping wing 20 and the fuselage 10.

[0045] It should be noted that the body 10 is provided with a crank-connecting rod mechanism, which is connected to the first disassembly and assembly connector 31 in a transmission manner, thereby enabling the first disassembly and assembly connector 31 to swing up and down relative to the body 10. Since the connection between the body 10 and the flapping wing 20 through the crank-connecting rod mechanism to enable the flapping wing 20 to swing up and down is existing technology, it will not be described in detail here.

[0046] like Figure 5 As shown, in some embodiments, the first connector 32 includes a plug shaft 321 and a first connecting rod 322, wherein the plug shaft 321 is used to plug into the plug hole 311 of the first detachable connector 31, one end of the first connecting rod 322 is connected to the plug shaft 321, and the other end of the first connecting rod 322 is connected to the flapping wing 20.

[0047] The insert shaft 321 is used to insert into the insertion hole 311 of the first disassembly and assembly connector 31 when the flapping wing 20 and the fuselage 10 are installed. When disassembly is required, the insert shaft 321 can be pulled out of the insertion hole 311 of the first disassembly and assembly connector 31, which realizes the quick disassembly and assembly of the flapping wing aircraft. The first connecting rod 322 plays a good connecting role between the insert shaft 321 and the flapping wing 20.

[0048] Specifically, the insertion hole 311 is a blind hole opened along the length direction of the first disassembly and assembly connector 31. The depth of the insertion hole 311 matches the length of the insertion shaft 321 so that the insertion shaft 321 can be fully inserted into the insertion hole 311 to ensure the reliability of the insertion fit.

[0049] The insertion shaft 321 and the insertion hole 311 have the same shape, which can be set to circular, geometric, or elliptical as needed. In this embodiment, both the insertion shaft 321 and the insertion hole 311 are set to square. The square insertion shaft 321 is inserted into the square insertion hole 311. By setting the shape, the insertion shaft 321 can be prevented from rotating circumferentially in the insertion hole 311. There is no need to set an additional limiting structure to limit the circumferential movement of the insertion shaft 321, thus ensuring installation stability.

[0050] Furthermore, a through hole 313 can be provided in the first disassembly and assembly connector 31. The through hole 313 is connected to the insertion hole 311. The machining status of the insertion hole 311 can be observed through the through hole 313, which avoids the insertion shaft 321 being unable to be inserted into the insertion hole 311 due to improper machining of the insertion hole 311. At the same time, the insertion status of the insertion shaft 321 into the insertion hole 311 can be observed through the through hole 313 during installation.

[0051] In some embodiments, the first connector 32 further includes a first connecting portion 323 disposed between the insert shaft 321 and the first connecting rod 322. When the insert shaft 321 is fully inserted into the insertion hole 311 of the first detachable connector 31, the first connecting portion 323 and the first detachable connector 31 abut against each other.

[0052] In this embodiment, the first connecting part 323 can connect and fix the insert shaft 321 and the first connecting rod 322. When the insert shaft 321 is fully inserted into the insertion hole 311 of the first disassembly and assembly connector 31, the first connecting part 323 and the first disassembly and assembly connector 31 abut against each other to ensure that the insert shaft 321 is inserted in place. Conversely, during installation, when the first connecting part 323 and the first disassembly and assembly connector 31 abut against each other, it indicates that the insert shaft 321 has been fully inserted into the insertion hole 311 of the first disassembly and assembly connector 31, which can serve as a reminder for installation.

[0053] Specifically, the cross-sectional dimension of the first connecting part 323 is larger than the diameter of the insert shaft 321 and the insertion hole 311, so that when the insert shaft 321 is fully inserted into the insertion hole 311, the first connecting part 323 can abut against the first disassembly connector 31 without being inserted into the insertion hole 311.

[0054] like Figure 4 and Figure 5 As shown, in some embodiments, the first disassembly and assembly component 30 further includes a first disassembly and assembly latch 33, which engages and locks the first connector 32 and the first disassembly and assembly connector 31 when the first connector 32 is in the first state.

[0055] The first disassembly and assembly latch 33 can lock the first connector 32 and the first disassembly and assembly connector 31 into place when the first connector 32 is inserted into the insertion hole 311 of the first disassembly and assembly connector 31. This ensures the reliability of the connection between the first connector 32 and the first disassembly and assembly connector 31 and prevents the first connector 32 from coming out of the insertion hole 311 of the first disassembly and assembly connector 31 during the use of the flapping-wing aircraft.

[0056] In some embodiments, the first disassembly / reassembly clip 33 is hinged to the first connector 32. When the first connector 32 is in the first state, the first disassembly / reassembly clip 33 is engaged and fixed with the first disassembly / reassembly connector 31. When the first connector 32 needs to switch from the first state to the second state, the first disassembly / reassembly clip 33 is separated from the first disassembly / reassembly connector 31.

[0057] The first disassembly and assembly clip 33 is rotatably connected to one of the first connector 32 and the first disassembly and assembly connector 31 to prevent the first disassembly and assembly clip 33 from being lost or dropped. The first disassembly and assembly clip 33 can be rotated to lock or unlock the first connector 32 and the first disassembly and assembly connector 31, making the operation convenient.

[0058] As an alternative to this embodiment, the first disassembly and assembly clip 33 can also be separately set from the first plug 32 and the first disassembly and assembly connector 31. When the first plug 32 and the first disassembly and assembly connector 31 are plugged in, the first disassembly and assembly clip 33 can also be used to lock the first plug 32 and the first disassembly and assembly connector 31.

[0059] like Figure 5 As shown, in some embodiments, the first disassembly connector 31 is provided with a snap-fit ​​protrusion 312 on the side away from the body 10, and the first disassembly head 33 includes a head body 331, which is hinged to the first connector 32. A buckle 3311 is provided at the end of the head body 331 extending toward the first disassembly connector 31. The buckle 3311 is configured to snap onto or disengage from the snap-fit ​​protrusion 312.

[0060] With the above configuration, when the first connector 32 is inserted into the insertion hole 311 of the first disassembly connector 31, the clip body 331 rotates relative to the first connecting part 323, causing the buckle 3311 to rotate toward the locking protrusion 312 until the buckle 3311 and the locking protrusion 312 engage. When the first connector 32 needs to be removed from the insertion hole 311 of the first disassembly connector 31, the clip body 331 rotates relative to the first connecting part 323, causing the buckle 3311 to disengage from the locking protrusion 312, thereby enabling the first connector 32 to be pulled out of the insertion hole 311 of the first disassembly connector 31.

[0061] Furthermore, the end of the clip head body 331 facing the flapping wing 20 is a pressing end. The rotating connection between the clip head body 331 and the connecting part is located between the pressing end and the buckle 3311. By pressing the pressing end, the buckle 3311 can be rotated to engage or disengage with the engaging protrusion 312, thereby achieving quick locking or unlocking between the first plug 32 and the first disassembly and assembly connector 31.

[0062] Optionally, an anti-slip part can be provided on the surface of the pressing end to facilitate hand operation. Specifically, the anti-slip part can be multiple rubber bumps protruding from the surface of the pressing end, but is not limited to this.

[0063] Regarding the specific connection between the card head body 331 and the connecting part, in some embodiments, the first card head 33 further includes a first card head connector 333. Both the card head body 331 and the first connecting part 323 are provided with connecting holes. The first card head connector 333 is installed in the connecting holes to achieve the hinged connection of the card head body 331 to the first connecting part 323.

[0064] For example, the first card head connector 333 may be a pin, shaft or other component, but is not limited to this. Other structures that can rotatably connect the card head body 331 to the first connecting part 323 are all within the protection scope of this application.

[0065] like Figure 4 and Figure 5 As shown, in some embodiments, the first disassembly / reassembly clip 33 further includes a first torsion spring 332, which is disposed between the clip body 331 and the first connecting rod 322 of the first connector 32, or the first torsion spring 332 is disposed between the clip body 331 and the insertion shaft 321 of the first connector 32, and the first torsion spring 332 applies a spring force to the clip 3311 to engage with the clip protrusion 312.

[0066] With the above configuration, when the insertion shaft 321 of the first connector 32 is inserted into the insertion hole 311 of the first detachable connector 31, the first torsion spring 332 applies a spring force to the buckle 3311 to engage with the buckling protrusion 312, so that the buckle 3311 is tightly engaged with the buckling protrusion 312, thereby preventing the buckle 3311 and the buckling protrusion 312 from separating during use, and improving the insertion reliability between the first connector 32 and the first detachable connector 31.

[0067] In this embodiment, the first torsion spring 332 is disposed between the pressing end of the clip body 331 and the first connecting rod 322. By pressing down the pressing end to compress the first torsion spring 332, the clip body 331's buckle 3311 is driven away from the snap-fit ​​protrusion 312 to rotate and separate, thereby unlocking the first connector 32 and the first disassembly connector 31. The flapping wing 20 and the fuselage 10 can be disassembled by pulling out the first connector 32. During installation, pressing down compresses the first torsion spring 332, causing the latch 3311 of the clip body 331 to lift. Then, the insertion shaft 321 of the first connector 32 is inserted into the insertion hole 311 of the first disassembly connector 31. When the first connecting part 323 and the first disassembly connector 31 come into contact, it indicates that the insertion shaft 321 has been fully inserted into the insertion hole 311. Releasing the pressing end causes the spring force of the first torsion spring 332 to drive the pressing end to reset and rotate, causing the latch 3311 to rotate and engage with the latching protrusion 312.

[0068] Of course, in other embodiments, the first torsion spring 332 can also be disposed between the clip body 331 and the insertion shaft 321 of the first plug 32. In this case, when disassembling, pressing down the pressing end stretches the first torsion spring 332, which can drive the buckle 3311 to disengage from the locking protrusion 312. When installing, pressing down the pressing end stretches the first torsion spring 332, which drives the buckle 3311 to lift up. When the insertion shaft 321 is fully inserted into the insertion hole 311, the pressing end is released, and the first torsion spring 332 drives the buckle 3311 to rotate and lock onto the locking protrusion 312, and drives the pressing end to rotate and reset.

[0069] In this embodiment, in order to prevent the first torsion spring 332 from deforming and shifting, a limiting groove 3312 is provided on the card head body 331, and the first torsion spring 332 is disposed in the limiting groove 3312, thereby restricting the first torsion spring 332 in the space of the limiting groove 3312 and reducing the deformation and shifting of the first torsion spring 332.

[0070] To enhance the engagement strength between the first connector 32 and the first detachable connector 31, preferably, two first detachable locking heads 33 are provided, respectively along the upper and lower ends of the first connecting portion 323. The two first detachable locking heads 33 engage and lock the upper and lower ends of the first connector 32 and the first detachable connector 31, thereby enhancing the engagement and locking strength.

[0071] like Figure 6 As shown, in some embodiments, the second disassembly assembly 40 includes a connecting seat 41 and a second plug 42. The connecting seat 41 is disposed at a second position 12 of the body 10 and has a plug groove 411. The second plug 42 is disposed at a position of the flapping wing 20 corresponding to the second position 12. The second plug 42 has a third state in which it is inserted into the plug groove 411 and can rotate relative to the plug groove 411, and the second plug 42 also has a fourth state in which it is disengaged from the plug groove 411.

[0072] With the above settings, when the second connector 42 is in the third state, the second connector 42 is inserted into the insertion slot 411 of the connector 41, thereby connecting the flapping wing 20 and the fuselage 10 at the second position 12. The second connector 42 can rotate relative to the connector 41 without affecting the up-and-down swing of the flapping wing 20, ensuring the normal flight of the flapping wing aircraft. When the second connector 42 is in the fourth state, the second connector 42 is disengaged from the insertion slot 411 along the notch 412 of the insertion slot 411, thereby separating the flapping wing 20 and the fuselage 10. Therefore, the matching setting of the second connector 42 and the insertion slot 411 realizes the quick installation and disassembly of the flapping wing 20 and the fuselage 10 at the second position 12.

[0073] Specifically, such as Figure 7 As shown, the insertion slot 411 is opened downward along the top of the connecting seat 41, and the notch 412 of the insertion slot 411 is provided on the top of the connecting seat 41. The second insertion connector 42 can be inserted downward along the notch 412 into the insertion slot 411 and transfer part of the weight of the flapping wing 20 to the connecting seat 41 to achieve force support.

[0074] like Figure 7 As shown, in some embodiments, the second connector 42 includes a flapping wing pivot 421 and a second connecting rod 422, wherein the flapping wing pivot 421 is rotatably disposed in the insertion slot 411 of the connector 41, one end of the second connecting rod 422 is connected to the flapping wing 20, and the other end of the second connecting rod 422 is connected to the flapping wing pivot 421.

[0075] The flapping wing pivot 421 is designed to be inserted into the insertion slot 411 of the connector 41 when the flapping wing 20 and the fuselage 10 are installed. When disassembly is required, the flapping wing pivot 421 can be removed from the insertion slot 411 of the connector 41, which realizes the quick assembly and disassembly of the flapping wing aircraft. The second connecting rod 422 plays a good connecting role between the flapping wing pivot 421 and the flapping wing 20.

[0076] Specifically, the flapping wing shaft 421 is provided with a mounting hole. The rotating connector 44 passes through the mounting hole and can be inserted into the insertion slot 411 through the notch 412, thereby realizing the rotatable connection of the flapping wing shaft 421 to the connecting seat 41.

[0077] Furthermore, the side of the connecting seat 41 is provided with a relief groove 413, which is connected to the insertion groove 411. During installation, the flapping wing shaft 421 drives the rotating connecting piece 44 to be inserted into the insertion groove 411 through the notch 412, and the end of the flapping wing shaft 421 is located in the relief groove 413, so that the flapping wing shaft 421 can rotate up and down relative to the connecting seat 41 along the relief groove 413.

[0078] It should be noted that the insertion groove 411 extends through the width of the connector 41, the clearance groove 413 extends through the insertion groove 411 along the length of the connector 41, and the length of the rotating connector 44 is greater than the width of the insertion groove 411 so that both ends of the rotating connector 44 can rotate and overlap the insertion groove 411 without coming off.

[0079] It is understandable that when the flapping wing aircraft is in flight, the flapping wing 20 is driven by the drive mechanism to swing up and down relative to the body 10 at the first position 11, thereby causing the second position 12 of the flapping wing 20 to rotate up and down relative to the body 10. Therefore, the up and down swing of the first disassembly and assembly connector 31 relative to the body 10 is an active motion, and the rotation of the flapping wing shaft 421 relative to the connecting seat 41 is a driven motion.

[0080] like Figure 6 and Figure 7 As shown, in some embodiments, the second disassembly assembly 40 further includes a second disassembly clip 43, which engages with the notch 412 of the insertion slot 411 when the second connector 42 is in the third state.

[0081] The second disassembly and assembly clip 43 is designed to engage with the notch 412 of the connector 411 when the second connector 42 is inserted into the connector slot 411 of the connector 41, thereby ensuring the reliability of the connection between the second connector 42 and the connector 41 and preventing the second connector 42 from coming out of the connector slot 411 during the use of the flapping-wing aircraft.

[0082] In some embodiments, the second disassembly / reassembly head 43 is rotatably mounted on the connecting seat 41. When the second connector 42 is in the third state, the second disassembly / reassembly head 43 rotates and engages with the notch 412 of the connector groove 411. When the second connector 42 needs to switch from the third state to the fourth state, the second disassembly / reassembly head 43 rotates and disengages from the notch 412 of the connector groove 411.

[0083] With the above settings, the second disassembly and assembly clip 43 is rotated to the connecting seat 41, which can prevent the second disassembly and assembly clip 43 from being lost or dropped. By rotating the second disassembly and assembly clip 43 relative to the connecting seat 41, the second disassembly and assembly clip 43 can be rotated to engage or disengage from the notch 412 of the insertion slot 411, which is convenient to operate.

[0084] As an alternative to this embodiment, the second disassembly clip 43 can also be separately set from the connector 41. After the second connector 42 and the connector 41 are plugged in, the second disassembly clip 43 can be snapped into the notch 412 to prevent the second connector 42 from coming out of the connector 41.

[0085] like Figure 6 and Figure 7As shown, in some embodiments, the second disassembly and assembly clip 43 includes a second connecting part 431 and a snap-fit ​​part 432, wherein the second connecting part 431 is rotatably connected to the connecting seat 41, the snap-fit ​​part 432 is fixedly connected to the second connecting part 431, and the snap-fit ​​part 432 can snap into or disengage from the notch 412 of the insertion slot 411.

[0086] With the above configuration, when the second connector 42 is inserted into the insertion slot 411 of the connector 41, the second connecting part 431 rotates relative to the connector 41, causing the locking part 432 to rotate toward the insertion slot 411 until the locking part 432 engages with the notch 412 of the insertion slot 411, thereby sealing the notch 412 and preventing the second connector 42 from coming out of the connector 411 from the notch 412. When the second connector 42 needs to come out of the insertion slot 411 of the connector 41, the second connecting part 431 rotates relative to the connector 41, causing the locking part 432 to rotate away from the insertion slot 411, so that the locking part 432 disengages from the notch 412 of the insertion slot 411, thereby allowing the second connector 42 to be removed from the insertion slot 411 of the connector 41 from the notch 412.

[0087] In this embodiment, the connector 41 is provided with a mounting groove 414, the second disassembly and assembly clip 43 is rotatably connected to the mounting groove 414, the second connecting part 431 is disposed away from the insertion groove 411, the clip part 432 is disposed corresponding to the insertion groove 411, the shape of the clip part 432 matches the shape of the notch 412 of the insertion groove 411, so that the clip part 432 can match and engage with the notch 412 of the insertion groove 411.

[0088] Specifically, connecting holes are provided at corresponding positions on the side walls of the second connecting part 431 and the mounting groove 414. The second snap-fit ​​connector 434 is disposed in the connecting holes, so that the second connecting part 431 can be rotatably mounted in the mounting groove 414 of the connecting seat 41. For example, the second snap-fit ​​connector 434 can be a pin or screw, but is not limited to these components.

[0089] To prevent the locking part 432 from dislodging from the notch 412 of the insertion slot 411 under external force, such as Figure 7 As shown, the second disassembly and assembly clip 43 of this application also includes a second torsion spring 433. The second torsion spring 433 is disposed between the second connecting part 431 and the connecting seat 41, or the second torsion spring 433 is disposed between the snap-fit ​​part 432 and the connecting seat 41. The second torsion spring 433 applies a spring force to the snap-fit ​​part 432 to snap into the notch 412 of the insertion groove 411.

[0090] With the above configuration, when the second connector 42 is inserted into the insertion slot 411 of the connector 41, the second torsion spring 433 applies a spring force to the locking part 432 to engage with the notch 412 of the insertion slot 411, so that the locking part 432 is tightly fitted with the notch 412 of the insertion slot 411, thereby preventing the locking part 432 from being dislodged from the notch 412 of the insertion slot 411 by external force, which would lead to the separation of the second connector 42 and the connector 41, and further improve the insertion reliability between the second connector 42 and the connector 41.

[0091] In this embodiment, the second torsion spring 433 is disposed between the second connecting part 431 and the mounting groove of the connecting seat 41. During installation, the snap-fit ​​part 432 is lifted upwards, causing the second connecting part 431 to rotate downwards and press down on the second torsion spring 433. After the second plug 42 is inserted into the insertion groove 411 of the connecting seat 41 through the notch 412, the snap-fit ​​part 432 is released. The elastic force of the second torsion spring 433 drives the second connecting part 431 to rotate upwards and reset, causing the snap-fit ​​part 432 to rotate and snap into the notch 412. During disassembly, the snap-fit ​​part 432 is lifted upwards, causing the second connecting part 431 to rotate downwards and press down on the second torsion spring 433, causing the snap-fit ​​part 432 to disengage from the notch 412. The second plug 42 is then removed from the insertion groove 411 of the connecting seat 41 through the notch 412 to achieve disassembly.

[0092] As an alternative embodiment, the second torsion spring 433 can also be disposed between the snap-fit ​​part 432 and the connecting seat 41. In this case, during installation, the snap-fit ​​part 432 is lifted upward and the second torsion spring 433 is stretched, causing the snap-fit ​​part 432 to disengage from the notch 412. The second connector 42 is then inserted into the insertion slot 411 of the connecting seat 41 through the notch 412. After releasing the snap-fit ​​part 432, the elastic force of the second torsion spring 433 drives the snap-fit ​​part 432 to rotate and snap into the notch 412. During disassembly, the snap-fit ​​part 432 is lifted upward and the second torsion spring 433 is stretched, causing the snap-fit ​​part 432 to disengage from the notch 412. The second connector 42 is then removed from the insertion slot 411 of the connecting seat 41 through the notch 412 to achieve disassembly.

[0093] As an alternative implementation, the second torsion spring 433 may be omitted, and the second disassembly and assembly clip 43 may be set as an elastic body. The elastic body can be used to press against the notch 412 by deformation interference, which can also seal the notch 412 of the insertion slot 411, and the elastic body will not come out of the notch 412.

[0094] It should be noted that the flapping wing 20 of the flapping wing aircraft is provided in two symmetrical positions on both sides of the fuselage 10. Due to the limited installation space at the tail of the fuselage 10, only one connecting seat 41 can be provided on the fuselage 10 in this application, and the second plugs 42 of the two flapping wings 20 are respectively connected to the plug slots 411 at both ends of the connecting seat 41.

[0095] It should be noted that in the actual disassembly and assembly process, the first disassembly and assembly component 30 can be disassembled and assembled first, followed by the second disassembly and assembly component 40, or the second disassembly and assembly component 40 can be disassembled and assembled first, followed by the first disassembly and assembly component 30. This embodiment does not impose any specific restrictions.

[0096] To facilitate understanding of the flapping-wing aircraft in this embodiment, its assembly and disassembly process is described below:

[0097] The description takes the example of first disassembling and assembling the first disassembly and assembly component 30 and then disassembling and assembling the second disassembly and assembly component 40.

[0098] Installation between one flapping wing 20 and fuselage 10: Press down the pressing end of the clamp body 331 and compress the first torsion spring 332, causing the latch 3311 of the clamp body 331 to lift up. Then, insert the insertion shaft 321 of the first connector 32 into the insertion hole 311 of the first disassembly connector 31. When the first connecting part 323 and the first disassembly connector 31 abut against each other, it indicates that the insertion shaft 321 has been fully inserted into the insertion hole 311. Then, release the pressing end of the clamp body 331. The elastic force of the first torsion spring 332 drives the pressing end to return to its original position and rotate, causing the latch 3311 to rotate and engage with the engagement protrusion 312. The flapping wing 20 and the fuselage 10 are installed in the first position 11; the locking part 432 is lifted upward and the second connecting part 431 is rotated downward to press down the second torsion spring 433. The second plug 42 is inserted into the plug slot 411 of the connecting seat 41 through the notch 412. The locking part 432 is then released. The elastic force of the second torsion spring 433 drives the second connecting part 431 to rotate upward and reset, causing the locking part 432 to rotate and lock into the notch 412. The installation of the flapping wing 20 and the fuselage 10 in the second position 12 is completed. The installation of the flapping wing 20 and the fuselage 10 on the other side is completed in accordance with the above steps, which will not be repeated here.

[0099] Disassembly between one flapping wing 20 and fuselage 10: Press down the pressing end of the latch body 331 and compress the first torsion spring 332, causing the latch 3311 of the latch body 331 to rotate away from the latching protrusion 312 to achieve separation. Pull the first connector 32 outward to remove it from the connector hole 311, thus disassembling the flapping wing 20 and fuselage 10 at the first position 11. Lift the latching part 432 upward to disengage it from the notch 412 of the connector slot 411, thereby driving the second connecting part 4 31. Rotate downwards to press down the second torsion spring 433, and take the second plug 42 out of the plug slot 411 of the connector 41 through the notch 412. Release the locking part 432. The elastic force of the second torsion spring 433 drives the second connecting part 431 to rotate upwards to reset, and drives the locking part 432 to rotate and lock into the notch 412, so as to realize the disassembly of the flapping wing 20 and the fuselage 10 at the second position 12. The disassembly of the flapping wing 20 and the fuselage 10 on the other side is completed in accordance with the above steps, which will not be repeated here.

[0100] It is understood that the embodiments of this application only focus on the structures in the flapping-wing aircraft that are related to the improvements of this application, and do not mean that the flapping-wing aircraft does not have other structures. For example, the flapping-wing aircraft also includes a tail fin 50 disposed at the tail of the fuselage 10. The tail fin 50 can control the flapping-wing aircraft's turning, diving and climbing. These structures are all within the protection scope of the embodiments of this application, and will not be described in detail here.

[0101] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
