Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle fuselages, in particular to a quick-detachable fuselage for an unmanned aerial vehicle. Background Art

[0002] With the rapid development of drone technology, drones are increasingly being used in logistics, agriculture, security and other fields, placing higher demands on the convenience and rapid deployment capabilities of drones. The fuselage and wings of traditional drones are usually fixed together, and the disassembly and assembly process is cumbersome, requiring professional tools and a long time, which is extremely inconvenient in emergency missions or frequent maintenance situations.

[0003] In recent years, modular drones have gradually become a research hotspot. These designs have achieved rapid assembly and disassembly of components and improved operational flexibility by improving the connection structure. However, existing technologies still have some problems in terms of rapid connection and disassembly, such as:

[0004] Insufficient connection stability: During high-speed flight or in harsh environments, the connection may not be strong enough, affecting flight safety.

[0005] Operational complexity: Some designs have high technical requirements for users, which is not conducive to rapid deployment.

[0006] Structural complexity: Some quick-connect mechanisms increase the structural complexity and manufacturing cost of the UAV.

[0007] Therefore, it is particularly important to develop a UAV design that can quickly connect the wing extension arm to the fuselage. This design needs to ensure structural strength and flight stability while achieving easier disassembly and assembly operations to meet the needs of different application scenarios.

[0036] In order to facilitate the problem to be solved, the embodiment of the utility model provides a quick-detachable fuselage for a drone. The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] See also Figure 1-4 This embodiment provides a quick-detachable fuselage of a drone, including:

[0038] The frame 100 is in an I-shape, and the wing extension arm 200 is connected to the frame 100 through a plug-in mechanism, and the wing extension arm 200 is connected to the frame 100 through a plug-in mechanism to complete the assembly, wherein the plug-in mechanism can complete the connection between the wing extension arm 200 and the frame 100 by plugging.

[0039] The pressing and locking mechanism is arranged on the frame 100 and can complete the squeezing action on the plug-in mechanism. The plug-in mechanism is squeezed by the pressing and locking mechanism, thereby completing the locking and further completing the connection between the frame 100 and the wing extension arm 200.

[0040] Specifically, the plug-in mechanism includes:

[0041] An L-shaped plug-in rod 301 is arranged at the plug-in end of the wing extension arm 200 and the frame 100, a concave elastic sheet 302 is arranged at the end of the plug-in rod 301 away from the wing extension arm 200, and a T-shaped locking rod 303 is arranged at the plug-in end of the frame 100 and the wing extension arm 200, and it is perpendicular to the frame 100 and can be inserted into the concave groove of the elastic sheet 302. When plugging in, the locking rod 303 is aligned with the groove of the elastic sheet 302 and plugged inward. During the plug-in process, the horizontal part of the locking rod 303 is inserted into the space between the elastic sheet 302 and the wing extension arm 200, and then the connection between the frame 100 and the wing extension arm 200 is completed under the joint restrictive effect of the elastic sheet 302 and the frame 100 on the wing extension arm 200.

[0042] Specifically, the elastic sheet 302 is provided with an arc groove 400 at the end away from the plug-in rod 301, and a square groove 500 is symmetrically provided on the inner circumference of the arc groove 400, and a hemispherical block 600 is provided at a position corresponding to the arc groove 400 of the locking rod 303, and a protruding block 700 that can be inserted into the square groove 500 is symmetrically provided on the outer circumference of the hemispherical block 600. In this way, during the insertion process, the hemispherical block 600 and the protruding block 700 on its surface will cause the elastic sheet 302 to deform under the action of extrusion until the hemispherical block 600 and the protruding block 700 are respectively inserted into the arc groove 400 and the square groove 500, and the elastic sheet 302 is reset, so that the wing extension arm 200 is prevented from detaching from the surface of the frame 100 by inserting the protruding block 700 into the square groove 500.

[0043] Specifically, the push-lock mechanism includes:

[0044] The push lock 801 is symmetrically arranged on the frame 100. The push lock 801 is a well-known thing. When it is pressed for the first time, its extended end can be locked, and it is reset when it is pressed for the second time.

[0045] The extrusion block 802 is arranged at the extended end of the push-lock device 801 and can extrude the elastic sheet 302. The arc block 803 is arranged at one end of the extrusion block 802 and can extrude the arc groove 400. When the push-lock device 801 is locked, its extended end will drive the extrusion block 802 and the arc groove 400 to synchronously extrude the outer surfaces of the elastic sheet 302 and the arc groove 400, thereby limiting their deformation and completing the locking.

[0046] Specifically, the arc groove 400 is inclined away from the elastic sheet 302 end, so when disassembly is required, the extrusion block 802 and the arc groove 400 simultaneously cancel the extrusion on the elastic sheet 302 and the outer surface of the arc groove 400, and use the inclined surface to allow the protruding block 700 to be separated from the square groove 500, thereby completing the disassembly.

[0047] Specifically, the plug-in ends of the frame 100 and the wing extension arm 200 are wrapped with rubber pads. The physical properties of the rubber pads make the two plugged in more tightly and have a certain buffering force.

[0048] When using:

[0049] When installation is required, it is only necessary to leave the push lock 801 in an unlocked state, align the end of the wing extension arm 200 with the elastic sheet 302 with the locking rod 303 and insert it. After it is fully inserted, press the push lock 801 to allow the push lock 801 to drive the extrusion block 802 and the arc block 803 on its surface to lock the elastic sheet 302 and the arc groove 400, thereby completing the connection. When disassembly is required, it is only necessary to reverse the operation.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
