It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, rather than all the structures. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0041] Reference herein to“an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification is not necessarily all referring to the same embodiment, nor is it necessarily referring to a particular alternative embodiment or set of alternative embodiments. It will be explicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0042] Please refer to Figures 1 to 7The application provides a connecting pipe assembly 100 which can be applied to connect a fuselage 200 and a tail fin 300 of a UAV, but is not limited thereto. The connecting pipe assembly 100 comprises a connecting pipe 10, a first clamping member 20 and a first locking member 30. The connecting pipe 10 has opposite first and second connecting ends 11 and 12, one of which is used to connect the fuselage 200, and the other of which is used to connect the tail fin 300. The first clamping member 20 cooperates with the first connecting end 11, one of the first clamping member 20 and the first connecting end 11 is provided with a first clamping protrusion 21, and the other is provided with a first clamping groove 111 which cooperates with the first clamping protrusion 21 to prevent the connecting pipe 10 from rotating about a central axis relative to the first clamping member 20, and the first clamping protrusion 21 is arranged such that when the connecting pipe 10 moves along the central axis away from the first clamping member 20, the first clamping protrusion 21 can be extruded to disengage from the first clamping groove 111. The first locking member 30 also cooperates with the first connecting end 11, and the first connecting end 11 is provided with a first locking groove 112 which cooperates with the first locking member 30 to prevent the connecting pipe 10 from moving along the central axis relative to the first clamping member 20.

[0043] The first clamping member 20 and the first locking member 30 which cooperate with the first connecting end 11 of the connecting pipe 10 can be arranged on the fuselage 200 or the tail fin 300 of the UAV when the connecting pipe assembly 100 is used, the cooperation of the connecting pipe 10 and the first clamping member 20 mainly realizes the stable connection of the connecting pipe 10 in the circumferential direction, and the cooperation of the connecting pipe 10 and the first locking member 30 mainly realizes the stable connection of the connecting pipe 10 in the axial direction. When it is necessary to disassemble the connecting pipe 10 from the fuselage 200 or the tail fin 300, the first locking member 30 is disengaged from the second locking groove 122, and then the connecting pipe 10 is pulled to move along the central axis away from the first clamping member 20, the first clamping protrusion 21 is extruded, so that the first clamping protrusion 21 and the first clamping groove 111 are disengaged, and the disassembly of the connecting pipe 10 from the fuselage 200 or the tail fin 300 is completed, which is convenient to operate.

[0044] The connecting pipe 10 is a tubular structure, for example, can be a tubular structure with a circular, rectangular or elliptical cross-sectional shape, but is not limited thereto, and in the embodiment of the application, the cross-sectional shape of the connecting pipe 10 is taken as an example for description.

[0045] The first clamping part 20 is connected with the first connecting end 11 of the connecting pipe 10 through the cooperation of the first clamping protrusion 21 and the first clamping groove 111. The first clamping protrusion 21 can be arranged on the first clamping part 20, and the first clamping groove 111 can be arranged on the first connecting end 11. Alternatively, the first clamping groove 111 can be arranged on the first clamping part 20, and the first clamping protrusion 21 can be arranged on the first connecting end 11. It should be noted that the connecting pipe 10 connects the fuselage 200 and the tail 300 in the unmanned aerial vehicle, and generally needs to have certain strength and hardness. However, the first clamping protrusion 21 needs to be extruded to be disengaged from the first clamping groove 111. In the following embodiments of the present application, the first clamping protrusion 21 is arranged on the first clamping part 20, and the first clamping groove 111 is arranged on the first connecting end 11 of the connecting pipe 10. The first clamping part 20 can be embedded in the connecting pipe 10, or the first clamping part 20 can be sleeved outside the connecting pipe 10.

[0046] As shown in Figures 2 to 6 In some embodiments, the first clamping part 20 is embedded in the connecting pipe 10, the first clamping protrusion 21 is arranged on the outer circumferential surface of the first clamping part 20, and the first clamping protrusion 21 is located at one end of the first clamping part 20 embedded in the connecting pipe 10. For example, the first clamping protrusion 21 can be located at the end of one end of the first clamping part 20 embedded in the connecting pipe 10. When the first connecting end 11 of the connecting pipe 10 is matched with the first clamping part 20, the connecting pipe 10 is directly sleeved on the first clamping part 20 from the first clamping part 20 to one end of the connecting pipe 10. In order to facilitate the cooperation of the connecting pipe 10 and the first clamping part 20, the first clamping protrusion 21 can also be provided with a guide surface towards one end of the connecting end. Of course, in order to ensure that the first clamping protrusion 21 can play a certain connecting role between the first clamping part 20 and the connecting pipe 10 after being matched with the first clamping groove 111, the end of the first clamping protrusion 21 away from the second connecting end 12 and the outer circumferential surface of the first clamping part 20 form a stepped structure. In this way, the first clamping protrusion 21 can be prevented from being disengaged from the first clamping groove 111 by slightly pulling the connecting pipe 10 along the central axis direction of the connecting pipe 10.

[0047] It should be noted that when the connecting pipe 10 moves away from the first clamping part 20 along the central axis direction, the first clamping protrusion 21 is extruded. The specific arrangement of the first clamping protrusion 21 on the first clamping part 20 is as follows: Figure 4 and Figure 5As shown in the drawings, along the circumferential direction of the first clamping member 20, an opening groove extending in the axial direction can be arranged on the opposite sides of the first clamping protrusion 21. In this way, by using the plasticity of the material itself, when the connecting pipe 10 moves in the axial direction relative to the first clamping member 20, the first clamping protrusion 21 can be extruded to disengage from the first clamping groove 111. At the same time, when the connecting pipe 10 rotates around the central axis relative to the first clamping member 20, the first clamping protrusion 21 cannot be extruded to deform the first clamping member 20 to disengage from the first clamping groove 111. The cooperation between the first clamping groove 111 and the first clamping protrusion 21 can prevent the connecting pipe 10 from rotating around the central axis relative to the first clamping member 20.

[0048] As shown in the drawings, Figure 5 and Figure 6 In some embodiments, a first limiting protrusion 22 can also be arranged on the outer circumferential surface of the first clamping member 20. The first connecting end 11 of the connecting pipe 10 is provided with a first limiting groove 113. The cooperation between the first limiting protrusion 22 and the first limiting groove 113 can limit the cooperation position of the connecting pipe 10 relative to the first clamping member 20 in the direction of the central axis of the connecting pipe 10. When the connecting pipe 10 is cooperated with the first clamping member 20, it is convenient to judge whether it is installed in place in the axial direction of the connecting pipe 10. At the same time, by matching the circumferential dimensions of the first limiting protrusion 22 and the first limiting groove 113 with each other, the relative rotation between the connecting pipe and the first clamping member can also be limited after the cooperation between the first limiting protrusion 22 and the first limiting groove 113. In addition, along the circumferential direction of the connecting pipe 10, the first limiting protrusion 22 can also correct the relative position of the connecting pipe 10 and the first clamping member 20. For example, the end of the first limiting protrusion 22 cooperating with the connecting pipe 10 can be provided with a circular arc guide surface, but it is not limited thereto.

[0049] When the connecting pipe assembly 100 is used, the first clamping member 20 and the first locking member 30 need to be arranged on the fuselage 200 or the tail 300 of the unmanned aerial vehicle. In order to facilitate the arrangement of the first clamping member 20 and the first locking member 30, as shown in the drawings, Figures 4 to 6 In some embodiments, the connecting pipe assembly 100 further comprises a sleeve pipe 40 having a mounting cavity 41. The first clamping member 20 is arranged in the mounting cavity 41, and the first connecting end 11 is embedded in the mounting cavity 41 to cooperate with the first clamping member 20. The first locking member 30 is rotatably arranged on the outer circumferential surface of the sleeve pipe 40, and the first locking member 30 is connected with the sleeve pipe 40 through a first elastic member 42. The first elastic member 42 is used to keep the cooperation between the first locking member 30 and the first locking groove 112. It should be noted that, as shown in the drawings, Figure 6As shown, the inner circumferential surface of the mounting cavity 41 is further provided with a mounting protrusion 43, for example, the mounting protrusion 43 can be in a U-shaped structure, the mounting protrusion 43 can cooperate with the first clamping piece 20 to limit the axial and circumferential relative position of the cooperation between the first clamping piece 20 and the outer sleeve 40, and it can be understood that the first clamping piece 20 is provided with a notch groove structure cooperating with the mounting protrusion 43.

[0050] The first connecting end 11 of the connecting pipe 10 is connected to the fuselage 200 of the unmanned aerial vehicle, as shown in the figure, Figure 8 The outer sleeve 40 can be embedded in the fuselage 200, so that the first clamping piece 20 arranged in the mounting cavity 41 of the outer sleeve 40 and the first locking piece 30 arranged on the outer circumferential surface of the outer sleeve 40 are arranged on the fuselage 200. Among them, the arrangement mode of the first clamping piece 20 in the outer sleeve 40 can be clamping fixation or threaded fastener fixation, but is not limited thereto. The first locking piece 30 is rotatably arranged on the outer circumferential surface of the outer sleeve 40, as shown in the figure, Figure 6 The first locking piece 30 can be arranged with the rotational center axis perpendicular to the axial direction of the outer sleeve 40, and in some embodiments, one end of the first locking piece 30 has a locking hook portion 31, and the other end has a poking portion 32. The locking hook portion 31 cooperates with the first locking groove 112, and the poking portion 32 is used to drive the first locking piece 30 to rotate against the elastic force of the first elastic piece 42 under the action of external force, so that the locking hook portion 31 is disengaged from the cooperation with the first locking groove 112. It should be noted that in order to facilitate the user to operate the poking portion 32, it can be understood that after the outer sleeve 40 is arranged in the fuselage 200, the poking portion 32 protrudes out of the fuselage 200. The first elastic piece 42 can be a spring, but is not limited thereto, and in some embodiments, the first elastic piece 42 and the locking hook portion 31 can be arranged on both sides of the rotational center axis of the first locking piece 30, respectively, and the first elastic piece 42 is arranged in a compressed state between the first locking piece 30 and the outer sleeve 40, so that the elasticity of the first elastic piece 42 can push the locking hook portion 31 to keep cooperating with the first locking groove 112.

[0051] As shown in the figure, Figures 2 to 5 And Figure 7As shown, in some embodiments, the connecting pipe assembly 100 can further comprise a second clamping member 50 and a second locking member 60, both of which are matched with the second connecting end 12 of the connecting pipe 10. When the first clamping member 20 and the first locking member 30 are arranged on the fuselage 200, the second clamping member 50 and the second locking member 60 can be arranged on the tail fin 300, so that the first connecting end 11 of the connecting pipe 10 is connected with the fuselage 200, and the second connecting end 12 is connected with the tail fin 300. The specific matching mode of the second clamping member 50 and the second locking member 60 with the second connecting end 12 is the same as that of the first clamping member 20 and the first locking member 30 with the first connecting end 11. Correspondingly, one of the second clamping member 50 and the second connecting end 12 is provided with a second clamping protrusion 51, and the other is provided with a second clamping groove 121. The second clamping groove 121 is matched with the second clamping protrusion 51 to prevent the connecting pipe 10 from rotating relative to the second clamping member 50 about the central axis thereof. The second connecting end 12 is provided with a second locking groove 122, which is matched with the second locking member 60 to prevent the connecting pipe 10 from moving relative to the second clamping member 50 along the central axis thereof. The specific arrangement structure of the second clamping member 50 and the second clamping protrusion 51 and the second locking member 60 and the second locking groove 122 can refer to that of the first clamping member 20 and the first clamping protrusion 21 and the first locking member 30, which will not be described herein again. Of course, the outer peripheral surface of the second clamping member 50 can also be provided with a second limiting protrusion 52, and correspondingly, the second connecting end 12 of the connecting pipe 10 is provided with a second limiting groove 123 matched with the second limiting protrusion 52.

[0052] As shown in FIGS. 1 and 2, in some embodiments, the first clamping member 20 and the first locking member 30 are arranged on the fuselage 200, and the second clamping member 50 and the second locking member 60 are arranged on the tail fin 300, so that the first connecting end 11 of the connecting pipe 10 is connected with the fuselage 200, and the second connecting end 12 is connected with the tail fin 300. Figure 3 and Figure 7 As shown in FIGS. 1 and 2, in some embodiments, the first clamping member 20 and the first locking member 30 are arranged on the fuselage 200, and the second clamping member 50 and the second locking member 60 are arranged on the tail fin 300, so that the first connecting end 11 of the connecting pipe 10 is connected with the fuselage 200, and the second connecting end 12 is connected with the tail fin 300. As shown in FIGS. 1 and 2, in some embodiments, the first clamping member 20 and the first locking member 30 are arranged on the fuselage 200, and the second clamping member 50 and the second locking member 60 are arranged on the tail fin 300, so that the first connecting end 11 of the connecting pipe 10 is connected with the fuselage 200, and the second connecting end 12 is connected with the tail fin 300.

[0053] With the second connecting end 12 of the connecting pipe 10 used for connecting the tail fin 300 of the unmanned aerial vehicle as an example, in use, the second clamping member 50 and the second locking member 60 need to be connected with the tail fin 300. For the convenience of setting the second clamping member 50 and the second locking member 60, as shown in Figure 4 、 Figure 5 and Figure 7 , in some embodiments, the connecting pipe assembly 100 further comprises a mounting member 70. The mounting member 70 has a connecting cavity 71, and a receiving groove 72 penetrating the side wall of the connecting cavity 71 is arranged on the side wall of the connecting cavity 71, and a pressing member 73 is movably arranged in the receiving groove 72. The second clamping member 50 is arranged in the connecting cavity 71, and the second connecting end 12 is embedded in the connecting cavity 71 to cooperate with the second clamping member 50. After the second connecting end 12 of the connecting pipe 10 is embedded in the connecting cavity 71 to cooperate with the second clamping member 50, the second locking groove 122 corresponds to the receiving groove 72, and when the second locking member 60 cooperates with the second locking groove 122, the second locking member 60 penetrates the second locking groove 122 and extends into the receiving groove 72, and by pressing the pressing member 73 in the receiving groove 72, the pressing member 73 drives the second locking member 60 to move under the action of external force to overcome the elastic force of the second elastic member 61, so that the second locking member 60 is disengaged from the second locking groove 122. The specific mounting mode of the mounting member 70 in the connecting cavity 71 can also be clamping or threaded connection, but is not limited thereto. The specific structure of the mounting member 70 is not limited in the embodiments of the application, and it can be set according to the specific mounting structure of the tail fin 300. The inner circumferential surface of the connecting cavity 71 is also provided with a mounting protruding structure cooperating with the second clamping member 50 to limit the relative position of the second clamping member 50 and the mounting member 70 in the axial and circumferential directions. It can be understood that the second clamping member 50 is also provided with a notch groove structure cooperating with the mounting protruding structure, and the mounting protruding structure on the inner circumferential surface of the connecting cavity 71 can also be a U-shaped structure, but is not limited thereto.

[0054] It should be noted that the second locking member 60 and the second locking groove 122 cooperate to prevent the connecting pipe 10 from moving relative to the second clamping member 50 along the central axis direction of the connecting pipe 10, for example, the second locking member 60 and the second locking groove 122 can be in cooperation when the second locking member 60 penetrates the second locking groove 122. When the second locking member 60 and the second locking groove 122 are disengaged, it means that the connecting pipe 10 can move relative to the second clamping member 50 along the central axis direction of the connecting pipe 10, at this time, it does not necessarily mean that the second locking member 60 is completely separated from the second locking groove 122, for example, when the second locking member 60 and the second locking groove 122 are disengaged, the end of the second locking member 60 can still be in the second locking groove 122 (for example, the end of the second locking member 60 does not lower than the inner wall of the connecting pipe 10), and the end of the second locking member 60 has an inclined guide surface, at this time, the movement of the connecting pipe 10 relative to the second clamping member 50 along the central axis direction of the connecting pipe 10 can further press the second locking member 60 by acting on the guide surface.

[0055] As shown in Figure 8 In some embodiments, the present application also provides a UAV. The UAV includes a fuselage 200, a tail fin 300, and the connecting pipe assembly 100 in any of the above embodiments, wherein one of the first connecting end 11 and the second connecting end 12 of the connecting pipe 10 in the connecting pipe assembly 100 is connected to the fuselage 200, and the other is connected to the tail fin 300.
