[0044] Before launching a parachute, aircraft and other flying vehicles equipped with whole-aircraft parachutes need to jettison the launch port cover or skin.

[0045] In related technologies, most parachute ejection mechanisms use a cutter to sever the securing cord, but this mechanical cutting method may tear the parachute.

[0046] Therefore, this application provides a parachute ejection device, an aircraft, and a vehicle to help reduce the risk of parachute rupture.

[0047] Reference Figure 1 In one embodiment of this application, the vehicle includes an aircraft 10 and a land vehicle 20, the land vehicle 20 being used to carry the aircraft 10. It is understood that the aircraft 10 is used for flight in the air, and the land vehicle 20 is used for travel on land environments such as roads; wherein, the land vehicle 20 can be configured as a vehicle similar to a pickup truck or van, thereby forming a carrying space to carry the aircraft 10. The aircraft 10 can be carried in a stowed state within the carrying space of the land vehicle 20, and the aircraft 10 can also detach from the carrying space of the land vehicle 20 and fly in an deployed posture.

[0048] In some implementations, refer to Figure 1 and Figure 2 The aircraft 10 includes a flight body 11 and a flight rotor 12. The flight body 11 includes a body support 13 and a skin 14. The skin 14 can be understood as a surface covering layer surrounding the body support 13, and the skin 14 can be made of materials such as metal plates. The skin 14 can be fixed to the body support 13 by adhesives or rivets, meaning the body support 13 can be understood as the skeleton of the flight body 11. Furthermore, the flight body 11 can enclose a crew cabin through the body support 13 and other structures, in which case the aircraft 10 can be understood as a manned aircraft.

[0049] In some embodiments, the aircraft 10 may include a flight body 11 and a foldable mechanism such as an arm, wherein one end of the arm is movable relative to the flight body 11, for example, by means of a rotatable connection or a telescopic connection; the other end of the arm is connected to the flight rotor 12 and can move closer to the flight body 11, which can be understood as the arm being able to be retracted as its end rotates or extends. Of course, the above-mentioned foldable mechanism can also be set as a foldable wing of a fixed-wing aircraft, and this embodiment does not limit this.

[0050] The aircraft 10 includes a main support frame 13 and a cover jetting device 300. The cover jetting device 300 is mounted on the main support frame 13, for example, by fasteners such as adhesives, rivets, or bolts. It can be understood that the cover jetting device 300 is used in the aircraft 10.

[0051] In addition, refer to Figure 2 and Figure 4The skin 14 of the aircraft 10 includes a cover plate segment 141; the aforementioned cover ejection device 300 is used to push open at least a portion of the cover plate segment 141 so that the skin 14 forms a launch port 143, and the parachute 400 of the aircraft 10 is used to be ejected from the launch port 143. It can be understood that the parachute 400 is arranged opposite to the cover plate segment 141 to facilitate the outward launch of the parachute 400. The parachute 400 can be launched using a separate launch device, etc., and this embodiment does not limit this.

[0052] Reference Figure 2 and Figure 3 The aforementioned cap-throwing device 300 includes a launcher 310, a launcher 320, and a fluid output device 330. The launcher 310 can be understood as a structure fixed relative to the launcher 320. For example, the launcher 310 is fixed to the aforementioned main body support 13, while the launcher 320 can move relative to the aforementioned main body support 13.

[0053] The launcher 310 has a receiving cavity 311, and the receiving cavity 311 has an outlet 312; it is understood that the outlet 312 is connected to the receiving cavity 311. The launcher 310 may be cylindrical, rectangular, or other shapes, and the receiving cavity 311 may be formed by machining, casting, or other methods.

[0054] One end of the emitter 320 is located inside the outlet 312, for example... Figure 2 The lower end of the emitter 320 is located within the outlet 312; the outer peripheral wall of the emitter 320 abuts against the edge of the outlet 312, and the emitter 320 can move relative to the outlet 312. It is understood that the outlet 312 can have a certain depth; for example, the outlet 312 can be orifice-shaped. Correspondingly, the emitter 320 can be rod-shaped, in which case the lower end of the rod-shaped emitter 320 can be slidably connected to the orifice-shaped outlet 312, thereby allowing the emitter 320 to have a large sliding stroke. Of course, the emitter 320 can also be spherical, cubic, or other shapes; this embodiment does not limit this.

[0055] Continue to refer to Figure 2 The other end of the launcher 320 is connected to the cover plate segment 141, for example, the upper end of the launcher 320 is connected to the cover plate segment 141 in the figure. It is understood that the end of the launcher 320 can be directly connected to the cover plate segment 141, or the launcher 320 can be indirectly connected to the cover plate segment 141 through other components. Furthermore, the end of the launcher 320 can be movably connected to the cover plate segment 141, for example, by a rotatable connection; the end of the launcher 320 can also be fixedly connected to the cover plate segment 141, for example, by welding or fastener connection.

[0056] In addition, refer to Figure 2The output end 331 of the fluid output device 330 is connected to the receiving cavity 311, and the fluid output device 330 is used to output fluid to the receiving cavity 311. (Refer to...) Figure 2 The fluid output device 330 can be entirely housed within the receiving cavity 311, or only the output end 331 can be housed within the receiving cavity 311. Alternatively, the fluid output device 330 can be entirely housed outside the receiving cavity 311, with the output end 331 connected to the corresponding inlet of the receiving cavity 311. In some embodiments, the fluid output device 330 can be configured as a pyrotechnic generator (or pyrotechnic gas generator, pyrotechnic device). The pyrotechnic generator can rapidly generate a high-temperature, high-pressure gas-solid mixture through the combustion of gunpowder, thereby forming a localized high pressure. Of course, the fluid output device 330 can also be configured as a water pump, air pump, or other liquid pump. In this case, the liquid pump can be configured with a larger output flow rate to quickly form a localized high pressure.

[0057] When the cover-throwing device 300 in the above embodiment is in use, if it is necessary to throw the cover section 141 to launch the parachute 400, the fluid output device 330 can output fluid to the receiving cavity 311. Since the outlet of the receiving cavity 311 is temporarily blocked by the launcher 320, the pressure in the receiving cavity 311 increases relatively quickly until it increases to the point that it can push the launcher 320 outward, thereby pushing the cover section 141 to achieve the cover-throwing operation.

[0058] Based on the above analysis, it can be seen that the cap-throwing device 300 can increase the pressure inside the receiving cavity 311 by outputting fluid to the receiving cavity 311 through the fluid output device 330. This increased pressure causes the launcher 320 to move relative to the outlet 312 of the receiving cavity 311, thereby pushing the cap section 141 to move, thus achieving the cap-throwing operation on the cap section 141. The movement trajectory of the launcher 320 relative to the outlet 312 is relatively fixed (e.g., Figure 2 The launcher 320 moves vertically as a whole, and its shape is designed to be relatively flat (compared to a sharp cutting blade), thereby reducing the risk of puncturing the parachute 400.

[0059] In some implementations, refer to Figure 2 and Figure 3 The throwing device 300 also includes a connecting pin 340; one end of the connecting pin 340 is connected to the launching base 310, for example, by means of plugging or welding; the other end of the connecting pin 340 is connected to the launching body 320, for example, by means of plugging or welding. The connecting pin 340 is used to disconnect under the action of the launching body 320, for example, the connecting pin 340 disconnects due to shear stress under the action of the launching body 320.

[0060] In this embodiment, before the connecting pin 340 is disconnected, the position of the launcher 320 is relatively fixed relative to the receiving cavity 311, thereby accumulating a certain pressure in the receiving cavity 311. After the connecting pin 340 is disconnected, the launcher 320 and the cover plate section 141 can have a certain impulse under the action of the large pressure in the receiving cavity 311, so as to ensure that the cover plate section 141 is separated from the body part 142 of the skin 14, thereby improving the success rate of the cover throwing operation.

[0061] In some implementations, refer to Figure 2 The end of the emitter 320 facing the fluid output device 330 has a recess 321, for example... Figure 2 The lower end of the emitter 320 is provided with the recess 321, which is connected to the receiving cavity 311. The recess 321 can be formed by machining, casting or other methods.

[0062] In this embodiment, for a fluid output device 330 that uses a pyrotechnic generator or a liquid pump with a large flow rate, the end of the emitter 320 facing the fluid output device 330 is provided with a recess 321, so that the recess 321 can accommodate the fluid initially output by the fluid output device 330, thereby enabling the fluid output device 330 to establish a stable fluid output process, thus facilitating the smooth output of fluid and improving the stability of the cover-throwing device 300.

[0063] In some implementations, refer to Figure 2 The launcher base 310 has a first through hole 313 on its side wall, and the launcher body 320 has a second through hole 324 on its side wall. The first through hole 313 and the second through hole 324 can be formed by drilling, casting, or other methods. The first through hole 313 can be provided on each of the opposite side walls of the launcher base 310; alternatively, the first through hole 313 can be provided on one side wall of the launcher base 310, and a blind hole can be provided on the inner side of the opposite side wall. Furthermore, when the launcher body 320 has the recess 321, the second through hole 324 can be correspondingly configured to penetrate the two oppositely arranged side walls of the recess 321.

[0064] The connecting pin 340 passes sequentially through the first through hole 313 and the second through hole 324. The outer peripheral wall of the connecting pin 340 abuts against the hole wall of the first through hole 313 and the hole wall of the second through hole 324, including direct abutment and indirect abutment, thereby achieving relative fixation between the launcher 320 and the launch base 310 and the receiving cavity 311. Part of the connecting pin 340 can be located within the recess 321, which can be understood as the connecting pin 340 extending into or passing through the recess 321. Furthermore, along the direction of movement of the launcher 320 relative to the receiving cavity 311, for example along... Figure 2In the vertical direction, the recess 321 includes a first portion 322 disposed on the connecting pin 340 facing away from the fluid output device 330, for example... Figure 2 The first part 322 of the central recess 321 is located on the upper side of the connecting pin 340.

[0065] In this embodiment, the first portion 322 is capable of guiding the fluid to flow away from the fluid output device 330, for example, guiding the fluid towards Figure 2 The fluid flows upwards, which reduces the overturning torque of the fluid on the launcher 320, thereby reducing the risk of jamming between the launcher 320 and the outlet 312 due to the overturning torque, and thus improving the success rate of the cover throwing operation.

[0066] In some embodiments, the outer peripheral wall of the connecting pin 340 is provided with a first adhesive layer, which abuts against the hole walls of the first through hole 313 and the second through hole 324, thereby improving the sealing degree of the connection of the connecting pin 340 and increasing the success rate of the launcher 320. It is understood that even when the outer peripheral wall of the connecting pin 340 directly abuts against the hole walls of the first through hole 313 and the second through hole 324, the connecting pin 340 also has a certain degree of sealing performance with the first through hole 313 and the second through hole 324, which can also enable the launcher 320 to be successfully launched to a certain extent.

[0067] In some implementations, refer to Figure 2 Along the direction of movement of the emitter 320 relative to the receiving cavity 311, for example, along the vertical direction shown in the figure, the recess 321 includes a second portion 323 disposed on the connecting pin 340 toward the fluid output device 330, for example... Figure 2 The second part 323 of the recess 321 is located on the lower side of the connecting pin 340. As a result, the sidewalls corresponding to the recess 321 have a certain solidity on both sides of the connecting pin 340, thereby improving the connection strength between the emitter 320 and the connecting pin 340.

[0068] In some implementations, reference continues. Figure 2 Relative to the wall of the receiving cavity 311, the end of the emitter 320 with a recess 321 protrudes in the direction toward the fluid output device 330, for example... Figure 2 The lower end of the emitter 320 protrudes from the wall of the receiving cavity 311, so that the recess 321 is closer to the fluid output device 330, thereby allowing the fluid to enter the recess 321 earlier. This is more conducive to the fluid output device 330 establishing a stable fluid output process, thus improving the operational stability of the cap-throwing device 300.

[0069] Furthermore, when the recess 321 includes a first portion 322 provided on the connecting pin 340 facing away from the fluid output device 330, the end of the emitter 320 with the recess 321 is provided to protrude in the direction toward the fluid output device 330 (relative to the wall of the receiving cavity 311), which helps to further reduce the overturning torque of the fluid on the emitter 320, thereby further reducing the risk of the emitter 320 getting stuck with the outlet 312, and thus further improving the success rate of the cap-throwing operation.

[0070] In some implementations, refer to Figure 2 The cap-throwing device 300 also includes at least one sealing ring 350, which may be made of materials such as plastic. The outer peripheral wall of the sealing ring 350 abuts against the edge of the outlet 312, and the inner peripheral wall of the sealing ring 350 abuts against the outer peripheral wall of the emitter 320. In some embodiments, an annular groove may be provided on the inner surface of the side wall corresponding to the outlet 312 or the outer surface of the emitter 320 to accommodate the sealing ring 350.

[0071] In this embodiment, the sealing ring 350 included in the cap-throwing device 300 can improve the sealing degree at the connection between the launcher 320 and the outlet 312, thereby increasing the success rate of the launcher 320 being launched outward.

[0072] In some implementations, refer to Figure 2 Along the direction in which the emitter 320 moves relative to the receiving cavity 311, for example, along the vertical direction shown in the figure, at least one sealing ring 350 is disposed between the output end 331 of the fluid output device 330 and the bottom wall of the recess 321, for example... Figure 2 The output end 331, a lower sealing ring 350, and the bottom wall of the recess 321 are arranged sequentially from bottom to top, so that part of the side wall of the recess 321 can abut against the sealing ring 350.

[0073] In this embodiment, a portion of the sidewall of the recess 321 can abut against the sealing ring 350, thereby allowing the portion of the sidewall of the recess 321 to further press against the sealing ring 350 by expanding outward in a certain amount under the action of the fluid, thereby further improving the sealing degree at the connection between the emitter 320 and the outlet 312, and further improving the success rate of the emitter 320 in launching outward.

[0074] In some implementations, refer to Figure 2The launcher 310 includes a first housing segment 314 and a second housing segment 315 arranged sequentially. The first housing segment 314 and the second housing segment 315 are arranged in a direction away from the launcher 320, for example, arranged sequentially from top to bottom as shown in the figure. The first housing segment 314 and the second housing segment 315 can each be cylindrical. Furthermore, the internal spaces of the first housing segment 314 and the second housing segment 315 form at least a partial receiving cavity 311. The wall thickness of the second housing segment 315 is greater than the wall thickness of the first housing segment 314. The fluid output device 330 is connected to the second housing segment 315, for example, by means of tight fit, bonding, welding, etc.

[0075] In this embodiment, since local high pressure is formed earlier near the fluid output device 330, the wall thickness of the second housing section 315 connected to the fluid output device 330 is set to be greater than the wall thickness of the first housing section 314. This is beneficial to improving the structural strength of the second housing section 315, reducing the risk of cracking of the second housing section 315 and the launcher 310, and improving the durability of the cover-throwing device 300.

[0076] In some implementations, refer to Figure 2 The output end 331 of the fluid output device 330 is disposed within the receiving cavity 311, and the outer peripheral wall of the output end 331 abuts against the wall of the receiving cavity 311, for example, by using an interference fit, thereby improving the sealing degree of the connection of the output end 331, which is beneficial to improving the launch success rate of the emitter 320 and the cover plate section 141. In addition, the outer peripheral wall of the output end 331 may be provided with a second adhesive layer, which abuts against the wall of the receiving cavity 311. The second adhesive layer can be formed by injecting or coating glue and curing, or injecting or coating molten plastic and curing, thereby further improving the sealing degree of the connection of the output end 331, which is beneficial to further improving the launch success rate of the emitter 320 and the cover plate section 141.

[0077] In some implementations, refer to Figure 2 The skin 14 includes a body portion 142, which has the aforementioned emission port 143. The body portion 142 and the cover plate segment 141 are separately disposed, meaning that the body portion 142 and the cover plate segment 141 are formed in different parts manufacturing processes, thereby improving overall manufacturing efficiency. A connecting adhesive 360 ​​is provided between the edge of the emission port 143 and the edge of the cover plate segment 141, and the connecting adhesive 360 ​​is fixedly connected to both the body portion 142 and the cover plate segment 141. The connecting adhesive 360 ​​can be an adhesive or similar material.

[0078] In this embodiment, the adhesive 360 ​​is fixedly connected to the body part 142 and the cover plate section 141 respectively, which helps to improve the waterproof performance and stability of the body part 142 and the cover plate section 141 of the skin 14.

[0079] In some implementations, refer to Figure 2 and Figure 5 ,in Figure 5 A schematic diagram of the cover-throwing device 300 from a bottom-view perspective is shown. The edge of the launch port 143 facing the launch base 310 has a first enclosure 144, for example, the first enclosure 144 is located on the lower side of the edge of the launch port 143 in the figure. The first enclosure 144 extends circumferentially along the launch port 143, and can be understood as being ring-shaped. Furthermore, the edge of the cover plate segment 141 facing the launch base 310 has a second enclosure 146, for example, the second enclosure 146 is located on the lower side of the edge of the cover plate segment 141 in the figure. The second enclosure 146 extends circumferentially along the cover plate segment 141, and can be understood as being ring-shaped.

[0080] The second enclosure 146 is disposed inside the first enclosure 144. The inner side of the first enclosure 144 and the outer side of the second enclosure 146 form a connection gap 147. The adhesive 360 ​​extends into the connection gap 147, thereby allowing more adhesive 360 ​​to be accommodated between the edge of the emission port 143 and the edge of the cover plate section 141. This helps to further improve the stability of the body part 142 of the skin 14 and the cover plate section 141 through the adhesive 360.

[0081] In some implementations, refer to Figure 2 A connecting ring plate 145 is provided on the side of the first enclosure 144 facing the fluid output device 330, and the connecting ring plate 145 covers the connecting gap 147; of course, the connecting ring plate 145 can also be provided on the side of the second enclosure 146 facing the fluid output device 330, and this embodiment does not limit this. The first enclosure 144 and the connecting ring plate 145 (or the second enclosure 146 and the connecting ring plate 145) can be connected by integral molding, welding or other methods.

[0082] In this embodiment, the connecting ring plate 145 covers the connecting gap 147, which can prevent the bonding adhesive 360 ​​from leaking out before curing, thereby helping to further improve the stability of the connection between the body part 142 of the skin 14 and the cover plate section 141.

[0083] In some implementations, refer to Figure 2The cover plate section 141 is provided with a mounting seat 148 on the side facing the launch base 310. For example, the mounting seat 148 is provided on the lower side of the cover plate section 141 in the figure. The mounting seat 148 is connected to the launch body 320, thereby improving the flatness of the side of the cover plate section 141 facing away from the launch base 310 (for example, the upper side of the cover plate section 141 in the figure), so that the side of the cover plate section 141 facing away from the launch base 310 (for example, the upper side of the cover plate section 141 in the figure) can be used as an outer surface to reduce the drag brought by the skin 14 during flight.

[0084] In some implementations, refer to Figure 2 The cover-throwing device 300 includes a fastener 370, which can be a rivet, screw, bolt, etc. The mounting base 148 is provided with a connecting through hole 149. One end of the fastener 370 (e.g., the lower end in the figure) passes through the connecting through hole 149 and is connected to the mounting base 148, for example, by riveting, threaded connection, etc.; the other end of the fastener 370 is connected to the cover plate section 141, for example, by riveting, abutment, etc.

[0085] In this embodiment, one end of the fastener 370 passes through the connecting through hole 149 and is connected to the mounting base 148, which helps to improve the connection efficiency between the cover plate section 141 and the emitter 320.

[0086] In some alternative embodiments, the skin 14 includes a body portion 142 having the aforementioned emission port 143, the edge of which is connected to a cover plate segment 141; the cover plate segment 141 is made of a brittle material, such as ABS plastic, foam board, etc., and the cover-throwing device 300 is used to break the cover plate segment 141 and push open at least a portion of the cover plate segment 141.

[0087] In this embodiment, the cover plate segment 141 is made of a brittle material that is easy to crack, thereby forming the firing port 143; at this time, the cover plate segment 141 can reduce the corresponding connecting structure and be made flatter overall, for example, by reducing the mounting base 148 in the aforementioned embodiment.

[0088] In some implementations, refer to Figure 4 and Figure 5 or refer to Figure 6 The aircraft 10 includes a memory and at least two of the aforementioned cover-throwing devices 300, each of which is spaced apart along the edge of the cover section 141. The memory stores a preset trigger sequence and is electrically connected to the controllable terminal of the fluid output device 330 of each cover-throwing device 300, so that each cover-throwing device 300 pushes the cover section 141 according to the preset trigger sequence. For example, see reference... Figure 4 and Figure 5The preset triggering sequence can allow all the cap-throwing devices 300 to be triggered simultaneously and perform the cap-throwing action at the same time, so that the cap section 141 is pushed open in a translational manner. Furthermore, referring to... Figure 6 It is possible that a portion of the cover-throwing device 300 on one side (e.g., the right side in the figure) is triggered first to perform the cover-throwing action, and a portion of the cover-throwing device 300 on the other side (e.g., the left side in the figure) is triggered later to perform the cover-throwing action, so that the cover plate segment 141 is pushed open in a flipping manner.

[0089] In this embodiment, the memory is used to store preset trigger timing sequences. Each cover-throwing device 300 pushes the cover plate segment 141 according to the preset trigger timing sequence. This is beneficial to meet the cover-throwing requirements at different flight speeds by storing different preset trigger timing sequences. For example, some need to be thrown straight, while others need to be thrown in a flip; or, the requirements of different cover-throwing directions can be met.

[0090] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
