It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0032] In order to solve the technical problem that the unmanned aerial vehicle landing gear disassembly process is complicated and time-consuming, which seriously affects the use efficiency of the unmanned aerial vehicle, the utility model provides a connecting structure and unmanned aerial vehicle, which can realize the quick disassembly, stable connection and flexible adjustment of the landing gear, thereby improving the use efficiency and safety of the unmanned aerial vehicle.

[0033] In the first aspect, please refer to Figures 1 to 3 The embodiment of the present scheme provides a connecting structure, which comprises: a connecting seat 1, a connecting joint 2 and an operating member 3, the connecting seat 1 is used for being fixed on the body of the unmanned aerial vehicle, the connecting seat 1 is provided with a connecting groove 11 inside, and one side of the connecting groove 11 is provided with an opening 12 in communication with the connecting groove 11; one end of the connecting joint 2 is used for being connected with the landing gear 5, and the other end of the connecting joint 2 is inserted and matched with the connecting groove 11; the operating member 3 is connected with both sides of the opening 12 of the connecting seat 1 respectively, and is used for adjusting the size of the opening 12 of the connecting seat 1 to clamp or unlock the connecting joint inside.

[0034] In the device, one end of the connecting joint 2 can be inserted and matched with the connecting groove 11 of the connecting seat 1, realizing the quick connection of the landing gear 5 and the body of the unmanned aerial vehicle. The setting of the opening 12 enables the operating member 3 to conveniently adjust the clamping degree of the connecting seat 1 to the connecting joint 2, and through the adjustment of the operating member 3, the size of the opening 12 of the connecting seat 1 can be controlled, and then the clamping or unlocking of the connecting joint 2 is realized. This process is efficient and convenient, and ensures the stability and safety of the unmanned aerial vehicle in the process of taking off and landing.

[0035] For the convenience of introduction, both sides of the opening 12 of the connecting seat 1 are defined as a first connecting part and a second connecting part, please refer to Figures 3 to 5 In some possible embodiments, the operating member 3 comprises a locking screw 31, one end of the locking screw 31 is rotationally connected with the first connecting part, and the other end of the locking screw 31 penetrates through the second connecting part and is threadedly connected with the second connecting part.

[0036] For the convenience of operation, further, in some possible embodiments, one end of the locking screw 31 penetrating through the second connecting part is provided with a first handle 32, which facilitates the user to hold and rotate the locking screw 31.

[0037] When the user needs to clamp the connecting joint 2, he can rotate the locking screw 31 through the first handle 32, so that it is screwed along the thread of the second connecting part, and the distance between the first connecting part and the second connecting part is pulled close, thereby reducing the opening 12 and achieving clamping of the connecting joint 2. Conversely, when the user needs to unlock the connecting joint 2, he only needs to reverse the rotation of the locking screw 31 using the first handle 32, so that the opening 12 increases accordingly, and the connecting joint 2 can be easily pulled out of the connecting groove 11.

[0038] Please refer to Figure 4 In one embodiment, in order to facilitate the flexible adjustment of the landing gear 5, the connecting groove 11 is designed in a circular shape, and one end of the connecting joint 2 is designed in a cylindrical structure matching the circular groove. Such a design allows the connecting joint 2 to be rotatably connected with the connecting groove 11, and when the connecting groove 11 is pulled apart, it allows the connecting joint 2 to rotate freely within the connecting groove 11 to adjust the installation angle of the landing gear 5, greatly improving its flexibility and being suitable for application occasions that require angle adjustment.

[0039] Further, in order to improve the stability and firmness of the connecting joint 2 in the connecting groove 11, the outer surface of the connecting joint 2 is provided with a plurality of limiting teeth along its peripheral direction, and the groove wall of the connecting groove 11 is provided with a plurality of limiting tooth grooves, each of which is matched in shape and size with each of the limiting teeth, so that they can be precisely engaged. When the connecting joint 2 is inserted into the connecting groove 11, the limiting teeth are engaged with the limiting tooth grooves, thereby effectively limiting the rotation angle of the connecting joint 2 relative to the connecting groove 11. This allows the connecting joint 2 to remain stable during use, preventing loose connection or damage due to excessive or insufficient rotation angle, thereby improving the reliability and safety of the entire connecting structure.

[0040] Please refer to Figure 5 In another embodiment, the cross section of the connecting groove 11 is in a polygonal structure, such as a triangle, a quadrilateral, or a pentagon. The polygonal structure of the connecting groove 11 allows the connecting joint 2 to be unable to rotate freely after being inserted into the connecting groove 11 due to the characteristics of the polygonal structure, thereby achieving the limitation of the rotation angle of the connecting joint 2.

[0041] Please refer to Figure 1 and Figure 6 In some possible embodiments, the connecting seat 1 is provided with two, and the two connecting seats 1 are arranged opposite to each other, and the quick release structure of the unmanned aerial vehicle landing gear 5 further includes an adjusting member 4 connected with the two connecting seats 1 for adjusting the distance between the two connecting seats 1, so that the quick release structure can be flexibly adjusted according to different sizes of the unmanned aerial vehicle or specific needs of the landing gear 5.

[0042] In one embodiment, the adjusting member 4 includes a first guide rail 41, a reversible screw 42, two threaded bases 43, a second handle 44, a second guide rail 45, two sliding seats 46, and two connecting rods 47.

[0043] Specifically, the second guide rail 45 is spaced apart and parallel to the first guide rail 41, the reversible screw 42 is rotatably arranged on the first guide rail 41, and the two ends of the reversible screw 42 are respectively connected to the two threaded bases 43 through threads, and the two threaded bases 43 are respectively connected to the two connecting seats 1. Rotating the reversible screw 42 can make the two threaded bases 43 move in opposite or same directions, thereby adjusting the distance between the connecting seats 1. In order to facilitate operation, one end of the reversible screw 42 protrudes from one end of the first guide rail 41, and the protruding end of the reversible screw 42 is provided with the second handle 44. The two sliding seats 46 are slidably arranged on the second guide rail 45, one end of the two connecting rods 47 is respectively connected to the two sliding seats 46, and the other end is respectively connected to the two threaded bases 43, and the connecting seat 1 is installed on the connecting rod 47.

[0044] The connecting seat 1 is connected to the UAV body through the adjusting member 4, and during use, the adjusting member 4 needs to be installed on the UAV body. During use, the user can hold the second handle 44 and rotate the reversible screw 42. Since the two ends of the reversible screw 42 are connected to the two threaded bases 43 in opposite threaded directions, rotating the reversible screw 42 will cause the two threaded bases 43 to move in opposite or same directions at the same time. This design allows the user to accurately center and adjust the distance between the two landing gears 5 as needed to adapt to different sizes of UAVs or specific landing gear 5 installation requirements.

[0045] When the reversible screw 42 is rotated to adjust the distance between the two threaded bases 43, the two sliding seats 46 can slide along the second guide rail 45, providing additional stability and support for the adjustment process. At the same time, the connecting rod 47 ensures the stability of the connection between the threaded base 43 and the sliding seat 46, thereby ensuring the stability and reliability of the entire adjusting member 4. Through such a design, the adjustment accuracy and stability of the connecting structure can be further improved. Moreover, the first guide rail 41, the second guide rail 45, and the two connecting rods 47 form a stable frame structure, which does not affect the installation of other equipment such as cameras and sensors on the bottom center of the UAV when installed on the UAV.

[0046] In a second aspect, the embodiment of the present application provides a UAV, comprising the connecting structure according to any one of the above embodiments, and further comprising a body and a landing gear, wherein the body is connected to the connecting seat, and the landing gear is connected to the connecting joint, so that the landing gear is connected to the body through the connecting seat and the connecting joint.
