[0002] With the rapid development of aircraft related technology, the type of aircraft is increasingly rich, covering fixed-wing aircraft, multi-rotor aircraft and flapping-wing aircraft and various forms. Among them, the appearance of part of the aircraft is similar to the common aircraft, and is equipped with a tail structure, and the tail structure plays a key role in the flight stability and controllability of the aircraft.

[0003] At present, the tail structure of the aircraft is usually composed of vertical tail and horizontal tail.

However, due to the complex environment in the flight process of the aircraft, collision is prone to occur, and the vertical tail as a more prominent component has a high probability of damage.

[0004] In the prior art, when the vertical tail of the aircraft is damaged, due to the design defects of the tail structure, the maintenance is difficult and the cost is high, which often leads to the fact that the whole aircraft cannot continue to be used, causing waste of resources and economic loss. In addition, the tail beam structure in the existing tail structure has many inconveniences in installation and disassembly, and adopts a complex connection mode, such as multi-bolt fastening, which not only increases the time cost of installation and maintenance, but also has high technical requirements for the installation personnel.

DETAILED DESCRIPTION

[0050] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with drawings in the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0051] The drawings in the utility model will be combined below Figure 1 to the drawings Figure 10 And the specific embodiments, the utility model is discussed in detail:

[0052] As Figures 1 to 10 The utility model provides a tail wing structure, it includes:

[0053] The mounting seat 1, the end face of mounting seat 1 is provided with slot 10, the circumferential surface of mounting seat 1 is provided with first perforation 11 that communicates slot 10, contact socket 14 is arranged in mounting seat 1, the one end of contact socket 14 is equipped with elastic contact sheet 141, the other end is used for the electric connection of rudder motor installed at tail wing assembly 2 place, the fixed mode of this contact socket 14 in mounting seat 1 and the electric connection implementation mode of the rudder motor installed at tail wing assembly 2 place are not specifically defined in the utility model, and the design selection of actual situation can be selected by the skilled person in the art;

[0054] Tail wing assembly 2, tail wing assembly 2 is fixedly installed on mounting seat 1;

[0055] The tail beam assembly 3 is provided with a first elastic buckle part 30, and the connecting end of the tail beam assembly 3 is provided with a contact plate 33, which is provided with a conductive area matched with the elastic contact sheet 141. The tail beam assembly 3 can be inserted into the mounting seat 1 along the insertion direction of the insertion slot 10, and the first elastic buckle part 30 is matched with the inner wall of the insertion slot 10 to form a first clamping connection, so that the tail beam assembly 3 cannot be pulled out in the reverse direction of the insertion direction.

[0056] The button part 4 is movably arranged in the first through hole 11 of the mounting seat 1 and can move along a movable path R1, and is used for pressing the first elastic buckle part 30. In the embodiment, the bottom of the button part 4 is a claw structure 40, which is hooked on the inner wall of the mounting seat 1.

[0057] The movable path R1 has a clamping position and an unlocking position. When the button part 4 is in the clamping position, the tail beam assembly 3 is inserted into the insertion slot 10, the contact plate 33 presses the elastic contact sheet 141 of the contact socket 14, and the conductive area of the contact plate 33 and the elastic contact sheet 141 abut each other to realize electrical conduction between them. When the button part 4 is in the unlocking position, the button part 4 presses the first elastic buckle part 30 to release the first clamping connection, and the tail beam assembly 3 can be separated from the insertion slot 10 in the reverse direction of the insertion direction.

[0058] It should be noted that the specific shape of the conductive area in the utility model is not limited, and can be designed and selected by those skilled in the art according to the actual situation. For example, in the embodiment, the conductive area is a long strip, and the long strip design has a long strip conductive range. Even if the tail beam assembly is displaced due to strong bumps during the flight of the aircraft, the long strip conductive range can greatly ensure that the elastic contact sheet and the conductive area are in contact, effectively solving the problem of poor contact caused by bumps, and providing reliable protection for the stable power supply of the aircraft tail wing structure.

[0059] In addition, it should be noted that the specific shape and number of the elastic contact sheet 141 in the utility model are not limited, and can be designed and selected by those skilled in the art according to the actual situation. Preferably, the elastic contact sheet 141 is V-shaped or arc-shaped, and the contact area with the conductive area can be increased when it is pressed.

[0060] The working principle of the tail wing structure in the utility model is as follows:

[0061] When installing, the first elastic buckle part 30 is pressed downward to be elastically deformed, at this time, the tail beam assembly 3 can be smoothly inserted into the mounting seat 1 along the insertion direction of the insertion slot 10. When reaching the buckle position, the first elastic buckle part 30 restores the deformation, forms the first clamping cooperation with the inner wall of the insertion slot 10, and forms one-way locking, so that the tail beam assembly 3 is firmly fixed in the mounting seat 1 and cannot be pulled out in the reverse direction of the insertion direction, the contact plate 33 extrudes the elastic contact piece 141 of the contact socket 14 to be elastically deformed, at the same time, the conductive area of the contact plate 33 abuts against the elastic contact piece 141 to realize the electrical conduction between them, and then realizes the electrical connection with the rudder assembly 2.

[0062] When the tail beam assembly 3 needs to be disassembled, the button part 4 is pushed to move from the buckle position to the unlocking position along the movable path R1. In this process, the button part 4 presses the first elastic buckle part 30 to make the first elastic buckle part 30 elastically deform again, so that the first clamping cooperation of the first elastic buckle part 30 with the inner wall of the insertion slot 10 is released. At this time, the tail beam assembly 3 can be separated from the insertion slot 10 in the reverse direction of the insertion direction, and the disassembly operation is completed.

[0063] In the tail wing structure of the utility model, when the tail beam assembly 3 is inserted into the insertion slot 10 of the mounting seat 1, the aircraft will be affected by airflow during flight, and due to the effective limitation of the structure of the mounting seat 1, the tail beam assembly 3 will only produce a small displacement. At this time, the elastic contact piece 141 of the contact socket 14 can compensate for the small displacement of the tail beam assembly 3 through the elastic deformation of itself, just like having a "tracking" function, always closely following the contact plate 33, ensuring that the two maintain good contact. In addition, the contact plate 33 is provided with a certain range of conductive area, as long as the elastic contact piece 141 is in the conductive area, electrical conduction can be realized, which further enhances the electrical connection stability of the tail wing structure under complex flight conditions, ensuring that the tail wing structure can always be stably contacted and powered.

[0064] Meanwhile, the tail wing structure in the utility model controls the clamping and unlocking of the first elastic buckle part 30 through the button part 4, compared with the traditional complex installation and disassembly mode, the convenience of installing and disassembling the tail beam assembly 3 is greatly improved. In actual use scenarios, for example, when the aircraft is maintained, the staff can quickly complete the replacement or maintenance of the tail beam assembly 3, saving a lot of time and labor cost.

[0065] In addition, the first clamping cooperation of the first elastic buckle part 30 with the inner wall of the insertion slot 10 can ensure that the tail beam assembly 3 remains stable in the mounting seat 1. During the flight of the aircraft, even if affected by external forces such as vibration and airflow impact, the tail beam assembly 3 is not easy to loosen or fall off, ensuring the stability of the tail wing structure, and further improving the flight safety and reliability of the aircraft as a whole.

[0066] Specifically, in this embodiment, a sloping guide groove 123 is provided on the top of the mounting base 1, and the sloping guide groove 123 is arranged along the insertion direction of the slot 10; for example Figure 9 As shown, the inclined guide groove 123 is located on the inner wall of the top of the upper seat 12. When the tail beam assembly 3 is inserted into the mounting base 1 along the insertion direction of the slot 10, the inclined guide groove 123 on the top of the mounting base 1 will press down on the first elastic latching part 30 of the tail beam assembly 3. During this process, the first elastic latching part 30 automatically deforms under pressure. As the tail beam assembly 3 continues to be inserted, until the first elastic latching part 30 reaches the latching position and fits with the inner wall of the slot 10, forming a stable first latching engagement, the quick insertion and installation of the tail beam assembly 3 is thus completed. At the same time, with the addition of the inclined guide groove 123, there is no need to manually press the first elastic latching part 30 of the tail beam assembly 3 during installation.

[0067] Furthermore, in some specific embodiments, such as Figure 1 , 2 As shown in Figures 5-7, the tail beam assembly 3 includes:

[0068] The tail boom connector includes an upper tail boom connector 31 and a lower tail boom connector 32. The upper tail boom connector 31 and the lower tail boom connector 32 are inserted and connected perpendicular to the insertion direction to form the tail boom connector. It should be noted that this utility model does not limit the specific insertion and connection method between the upper tail boom connector 31 and the lower tail boom connector 32, as long as the two can be inserted and matched. The lower tail boom connector 32 has a contact plate receiving cavity inside, and the contact plate receiving cavity contains a contact plate 33 for forming an electrical connection with a switch in the tail fin assembly 2, etc. The lower tail boom connector 32 has a second elastic buckle part 321; the first elastic buckle part 30 is disposed on the upper tail boom connector 31.

[0069] The tail beam body 34 has a second through hole 341 on its circumferential surface. When the second elastic buckle part 321 is pressed, the end of the tail beam body 34 can be sleeved on the outer wall of the tail beam connector along the insertion direction, and placed in the second through hole 341 through the second elastic buckle part 321, forming a second snap-fit ​​between the second elastic buckle part 321 and the tail beam connector.

[0070] When installing, the contact plate 33 is installed in the contact plate accommodating cavity of the tail beam lower connecting piece 32, then the tail beam upper connecting piece 31 and the tail beam lower connecting piece 32 are inserted and connected, and the complete tail beam connecting piece is formed. Again, the second elastic buckle part 321 of the tail beam lower connecting piece 32 is pressed, and the second elastic buckle part 321 is elastically deformed. At this time, the tail beam body 34 can be sleeved on the outer wall of the tail beam connecting piece along the insertion direction. When the tail beam body 34 is sleeved in place, the second elastic buckle part 321 restores to the original state and is placed in the second perforation 341, and further forms a second clamping connection with the tail beam connecting piece, so that the tail beam body 34 is firmly fixed on the tail beam connecting piece.

[0071] In the utility model, the tail beam connecting piece adopts the mode of inserting and connecting the upper connecting piece and the lower connecting piece, so that the tail beam connecting piece is convenient to assemble and disassemble during production and maintenance. If a connecting piece fails, the tail beam upper connecting piece 31 or the tail beam lower connecting piece 32 or the contact plate 33 can be replaced alone, so that the maintenance cost and difficulty are reduced. Meanwhile, the tail beam body 34 is installed and fixed by pressing the second elastic buckle part 321, so that the operation is simple, the tail beam body 34 and the tail beam connecting piece can be quickly separated during maintenance, and the maintenance efficiency is improved.

[0072] Specifically, in the embodiment, the second elastic buckle part 321 includes a second guide inclined surface 3211 and a second elastic pressing part 3212 which are sequentially arranged along the insertion direction of the insertion slot 10. When the tail beam body 34 is inserted into the tail beam connecting piece along the insertion direction of the insertion slot 10, the tail beam body 34 will extrude the second guide inclined surface 3211 of the second elastic buckle part 321. In this process, the second elastic buckle part 321 is automatically deformed under extrusion. When the tail beam body 34 is sleeved in place, the second elastic buckle part 321 restores to the original state, and the second elastic pressing part 3212 is placed in the second perforation 341, and further forms a second clamping connection with the tail beam connecting piece, so that the tail beam body 34 is firmly fixed on the tail beam connecting piece.

[0073] When the tail beam body 34 needs to be disassembled, only the second elastic pressing part 3212 of the second elastic buckle part 321 needs to be pressed to deform, the second elastic pressing part 3212 is separated from the second perforation 341, then the tail beam body 344 can be disassembled along the reverse direction of the insertion direction, and the disassembly operation is completed.

[0074] Further, in some more specific embodiments, as shown in Figs. Figure 1 , 2 , 5-7, the tail beam body 34 is provided with a plurality of first limiting grooves 342 which are arranged at intervals along the circumferential direction. The circumferential surface of the tail beam connecting piece is formed with a first limiting protrusion 311 which matches the first limiting groove 342 and is used for limiting the tail beam body 34. In the embodiment, two first limiting grooves 342 and two first limiting protrusions 311 are symmetrically arranged.

[0075] When the tail beam body 34 is sleeved on the outer wall of the tail beam connecting piece along the insertion direction, the first limiting protrusion 311 gradually aligns with the corresponding first limiting groove 342, so that the tail beam body 34 has a clear positioning guide during installation and can only be sleeved at a specific angle and position, ensuring the accuracy of installation. After installation is completed, the first limiting protrusion 311 is embedded in the first limiting groove 342. During equipment operation, when the tail beam body 34 is subjected to an external force that attempts to rotate it circumferentially around the tail beam connecting piece, the first limiting protrusion 311 interacts with the groove wall of the first limiting groove 342. Because the shape and position of the first limiting protrusion 311 and the first limiting groove 342 match each other, the groove wall of the first limiting groove 342 prevents the rotation of the first limiting protrusion 311, thereby limiting the circumferential rotation of the tail beam body 34 around the tail beam connecting piece, and playing a role in stabilizing the position of the tail beam body 34.

[0076] Further, in some specific embodiments, as shown in Figure 2 The mounting seat 1 includes an upper seat body 12 and a lower seat body 13, which are connected by insertion along a direction perpendicular to the insertion direction to form the mounting seat 1, facilitating assembly and disassembly.

[0077] As shown in Figure 4 The lower seat body 13 is provided with a second limiting protrusion 131, and the tail beam connecting piece is provided with a second limiting groove 35 corresponding to the second limiting protrusion 131 for limiting the tail beam assembly 3.

[0078] When the tail beam assembly 3 is inserted into the mounting seat 1 along the insertion direction of the insertion slot 10, the end of the tail beam connecting piece gradually approaches the second limiting protrusion 131 in the lower seat body 13. As the tail beam assembly 3 continues to be inserted, the second limiting protrusion 131 gradually embeds into the second limiting groove 35. When the tail beam assembly 3 is inserted in place, the second limiting protrusion 131 tightly cooperates with the second limiting groove 35 to limit the tail beam assembly 3 from moving further along the insertion direction and rotating circumferentially around the insertion direction in the mounting seat 1.

[0079] In this embodiment, the second limiting protrusion 131 is a U-shaped limiting protrusion, and the second limiting groove 35 is a U-shaped limiting groove. At the same time, an arc-shaped supporting structure 132 can be provided in the lower seat body 13 for supporting the tail beam assembly 3 and playing a role in stabilizing and supporting.

[0080] Further, in some specific embodiments, as shown in Figure 1 , 2As shown, the tail wing assembly 2 includes a vertical tail wing 20 and a horizontal tail wing 21. The horizontal tail wing 21 is provided with an avoiding opening 211 at the middle portion close to one side of the tail beam assembly 3. The upper seat body 12 and the lower seat body 13 are respectively installed on the upper and lower sides of the avoiding opening 211 of the horizontal tail wing 21, so as to realize the fixed connection between the horizontal tail wing 21 and the mounting seat 1. In this embodiment, after the upper seat body 12 and the lower seat body 13 are respectively installed on the upper and lower sides of the avoiding opening 211 of the horizontal tail wing 21, bolts, screws and the like are arranged at the outer edges of the upper seat body 12 and the lower seat body 13, so as to realize the bolt locking and fixed connection among the upper seat body 12, the horizontal tail wing 21 and the lower seat body 13.

[0081] The vertical tail wing 20 is vertically arranged above the mounting seat 1 and is detachably connected with the upper seat body 12, so as to facilitate the dismounting and mounting of the vertical tail wing 20.

[0082] Specifically, as shown in the figure, Figures 1-3 The upper seat body 12 is provided with a stroke groove 121 matching the shape of the bottom of the vertical tail wing 20 close to one side of the vertical tail wing 20. The stroke groove 121 is provided with a third elastic buckle portion 122 close to one side of the tail beam assembly 3. The third elastic buckle portion 122 is provided with a hook-shaped groove 1221.

[0083] The bottom of the vertical tail wing 20 is provided with a hook-shaped structure 201 matching the hook-shaped groove 1221 close to one side of the tail beam assembly 3. The hook-shaped structure 201 is arranged in the hook-shaped groove 1221, so as to form the third clamping cooperation between the vertical tail wing 20 and the upper seat body 12.

[0084] The upper seat body 12 is designed with a stroke groove 121 matching the shape of the bottom of the vertical tail wing 20, which provides a precise guide path for the installation of the vertical tail wing 20. When installing the vertical tail wing 20, the stroke groove 121 can provide precise guidance for it, so that the vertical tail wing 20 can only smoothly advance along a specific path, greatly reducing the possibility of misalignment during installation.

[0085] Meanwhile, the third elastic buckle portion 122 is arranged at the side of the stroke groove 121 close to the tail beam assembly 3. The third elastic buckle portion 122 is provided with a first guide inclined surface 1222, a hook-shaped groove 1221 and a first elastic pressing portion 1223 in sequence close to the side of the stroke groove 121, as shown in the figure. Figure 9The bottom of the vertical tail 20 is provided with a hook-shaped structure 201 at the corresponding position. In the initial stage of installation, the bottom of the vertical tail 20 is pushed along the stroke groove 121, and the hook-shaped structure 201 of the bottom of the vertical tail 20 gradually approaches and contacts the first guide inclined surface 1222 of the third elastic buckle part 122. Due to the good elasticity of the third elastic buckle part 122, the third elastic buckle part 122 will be deformed under the extrusion of the continuous pushing of the hook-shaped structure 201.

[0086] When the vertical tail 20 is pushed to the preset position, the third elastic buckle part 122 restores to the original shape by virtue of the elasticity thereof, and the hook-shaped groove 1221 thereon restores to the initial shape and is just sleeved with the hook-shaped structure 201 of the bottom of the vertical tail 20. The hook-shaped groove 1221 and the hook-shaped structure 201 are tightly matched, forming a stable third clamping cooperation, which firmly fixes the vertical tail 20 on the upper seat body 12. During the operation of the equipment, the clamping cooperation can effectively resist various external forces received by the vertical tail 20, preventing displacement or loosening thereof.

[0087] If it is necessary to disassemble the vertical tail 20, it is only needed to deform the first elastic pressing part 1223 of the third elastic buckle part 122, so that the hook-shaped groove 1221 is separated from the hook-shaped structure 201, and then the vertical tail 20 can be taken out along the reverse direction of the stroke groove 121, completing the disassembly operation.

[0088] Through the pressing type installation design, in cooperation with the precise guide stroke groove 121, the installation process of the vertical tail 20 is greatly simplified. Compared with the traditional complex connection mode such as multi-bolt fastening, the installer does not need to spend a lot of time on positioning and tightening operation, greatly saving the installation time and improving the production or maintenance efficiency.

[0089] It should be noted that the vertical tail 20 in the utility model can be an integral structure or a split structure. In this embodiment, the vertical tail 20 comprises a vertical tail body and a vertical tail connecting piece 22 arranged at the bottom of the vertical tail body, the vertical tail body and the vertical tail connecting piece 22 are connected in a plug-in manner, and glue is arranged at the connection position to enhance the connection strength. Correspondingly, the hook-shaped structure 201, the third limiting groove 202, the inclined surface 202-1 and the fourth limiting groove 203 are arranged at the bottom of the vertical tail connecting piece 22.

[0090] Further, in some specific embodiments, as shown in the drawings, Figure 3 The upper surface of the stroke groove 121 is provided with a third limiting protrusion 1211 and a fourth limiting protrusion 1212 which are arranged at intervals along the length direction thereof.

[0091] The bottom of the vertical tail 20 is provided with a third limiting groove 202 and a fourth limiting groove 203 matched with the third limiting protrusion 1211 and the fourth limiting protrusion 1212 respectively, for limiting the vertical tail 20.

[0092] When the bottom of the vertical tail 20 is pushed along the stroke groove 121, the third limiting groove 202 and the fourth limiting groove 203 will gradually approach the third limiting protrusion 1211 and the fourth limiting protrusion 1212. With the pushing, the third limiting protrusion 1211 will be embedded into the third limiting groove 202, and the fourth limiting protrusion 1212 will also be embedded into the fourth limiting groove 203. Since the third limiting groove 202 and the third limiting protrusion 1211 are matched, they jointly limit the position of the vertical tail 20 in the stroke groove 121, preventing the vertical tail 20 from deviating. Through the cooperation of the third limiting protrusion 1211 and the third limiting groove 202, and the fourth limiting protrusion 1212 and the fourth limiting groove 203, accurate positioning is provided for the installation of the vertical tail 20, and workers can quickly and accurately install the vertical tail 20 to the predetermined position without repeated adjustment, greatly improving the assembly efficiency. At the same time, the accurate installation positioning ensures the relative position accuracy between the vertical tail 20 and the upper seat body 12, which is beneficial to improve the assembly quality of the entire tail structure and ensure that the tail structure can work normally in the subsequent use process.

[0093] At the same time, the length direction size of the fourth limiting groove 203 is greater than the size of the fourth limiting protrusion 1212, forming an avoiding space, so that the installer can smoothly push the vertical tail 20 along the stroke groove 121 to the preset position.

[0094] When it is necessary to disassemble the vertical tail 20 for maintenance, due to the avoiding space between the fourth limiting groove 203 and the fourth limiting protrusion 1212, the installer can use this space to more conveniently push out the vertical tail 20 along the reverse direction of the stroke groove 121. In the pushing-out process, the cooperation relationship between the third limiting protrusion 1211 and the third limiting groove 202, and the fourth limiting protrusion 1212 and the fourth limiting groove 203 still plays a certain guiding role, making the disassembly process more stable and accurate, and avoiding the collision or damage of the vertical tail 20 with the stroke groove 121 during the disassembly process.

[0095] In some more specific embodiments, such as Figure 3As shown, the third limiting protrusion 1211 is provided with an oblique notch 1211-1 away from one side of the tail beam assembly 3, the third limiting groove 202 is formed with an oblique chamfer surface 202-1 matched with the oblique notch 1211-1, and the oblique chamfer surface 202-1 is inserted into the oblique notch 1211-1. During the pushing process, the oblique chamfer surface 202-1 will naturally slide along the inclination angle of the oblique notch 1211-1. The design of the inclined structure provides a guiding effect for the accurate butt joint of the third limiting groove 202 and the third limiting protrusion 1211, so that the vertical tail wing 20 can move more accurately to the correct position during the installation and pushing process.

[0096] The fourth limiting protrusion 1212 is provided with a flange structure 1212-1 on both sides for limiting the vertical tail wing 20 and achieving the limiting of the vertical direction of the vertical tail wing 20.

[0097] It should be noted that the specific structures of the first elastic buckle part 30, the second elastic buckle part 321 and the third elastic buckle part 122 are not limited in the utility model, and can be designed and selected by those skilled in the art according to actual conditions, for example, in the embodiment, the first elastic buckle part 30 is an integral structure with the tail beam assembly 3, and correspondingly, a U-shaped gap is formed at the position of the tail beam assembly 3 where the first elastic buckle part 30 is arranged. The second elastic buckle part 321 and the third elastic buckle part 122 can be designed according to the first elastic buckle part 30.
