[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of the present invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified, and "several" means one or more.

[0026] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] Please see Figure 1One embodiment of the present invention provides a folding-wing drone swarm launch device, including: a mounting body 10 and a plurality of drone launch components 20, wherein the drone launch components 20 are uniformly mounted on the mounting body 10.

[0028] Please see Figures 2 to 4 The drone launch assembly 20 includes a launch tube 21, a gas generator 22, and a piston 23. The launch tube 21 is mounted on the mounting body 10 and is used to hold the drone and guide it during launch. The gas generator 22 is located at the tail end of the launch tube 21 and is used to provide high-pressure gas. The piston 23 is movably disposed inside the launch tube 21 and forms a sealed cavity 30 with the inner wall of the launch tube 21 and the gas generator 22. A positioning part 231 is formed on the side of the piston 23 away from the sealed cavity 30. The positioning part 231 is used to position and cooperate with the drone, so that the drone is less likely to rotate circumferentially or deviate radially relative to the piston 23 when it moves along the launch tube 21. After the gas generator 22 fills the sealed cavity 30 with high-pressure gas, the gas pressure inside the sealed cavity 30 increases and expands, causing the piston 23 to move along the launch tube 21 under the drive of the gas pressure inside the sealed cavity 30. This causes the piston 23 to push the drone along the launch tube 21 and eject the drone from the head end of the launch tube 21.

[0029] Piston 23 is made entirely of ABS resin 3D printing technology. The resin itself is not easily corroded, and it is resistant to acids and alkalis, anti-aging, lightweight and quick to form.

[0030] In some alternative implementations, the piston 23 is connected to the gas generator 22 via a flexible pull rope 232. When the piston 23 moves to the head end of the launch tube 21, the flexible pull rope 232 becomes taut and does not detach from the launch tube 21, and the drone is ejected. This avoids the piston 23 being launched along with the drone and affecting or colliding with other drones ejected from the launch tube 21, and also avoids the trouble of needing to retrieve the piston 23 after it detaches from the launch tube 21.

[0031] Please see Figure 5 In some alternative embodiments, the UAV launch assembly 20 also includes a mounting base 24, which is disposed at the tail end of the gas generator 22. The mounting base 24 is provided with a positioning groove 241, and the gas generator 22 is disposed on the mounting base 24 and positioned and engaged with the positioning groove 241.

[0032] The installation method of the gas generator 22 can be selected according to actual needs. In some optional embodiments, the gas generator 22 is detachably mounted on the mounting base 24 by a plurality of first threaded locking elements 242. Of course, the installation method of the gas generator 22 is not limited to this. Those skilled in the art can also select other suitable structures according to the teachings of the present invention. For example, the gas generator 22 can also be directly threaded into the mounting base 24, or it can be snapped into the mounting base 24 by a snap-fit ​​structure.

[0033] The fixing method of the mounting base 24 can be selected according to the actual needs. In order to facilitate the quick installation of the gas generator 22, in some optional embodiments, the tail end of the launch tube 21 is provided with a bottom cover 211 and a bottom sleeve 212. The bottom cover 211 is provided with a boss 213 and a fixing channel 214. The mounting base 24 is inserted into the fixing channel 214, the boss 213 is inserted into the bottom sleeve 212, and the bottom sleeve 212 is inserted into the launch tube 21. The bottom cover 211 and the mounting base 24 together close the opening at the tail end of the launch tube 21.

[0034] In some alternative embodiments, a quick-connect plug 25 is provided on the side of the mounting base 24 away from the gas generator 22. The quick-connect plug 25 is electrically connected to the gas generator 22, which facilitates the gas generator 22 located in the launch tube 21 to be quickly connected to an external power source.

[0035] The quick-connect plug 25 can be fixed in a suitable way according to actual needs. In some optional embodiments, the quick-connect plug 25 is detachably mounted on the mounting base 24 by a plurality of second threaded locking elements 251.

[0036] In some alternative embodiments, the launch tubes 21 of each UAV launch assembly 20 are arranged in an array on the mounting body 10. In this embodiment, the mounting body 10 is provided with 30 UAV launch assemblies 20, and the maximum number of UAVs launched at one time is 30.

[0037] When the cross-section of the launch tube 21 is rectangular, the stress concentration at the inner corner of the launch tube 21 leads to structural instability. In some optional embodiments, multiple angle iron reinforcements 215 are provided on the outer side of the launch tube 21. The multiple angle iron reinforcements 215 are arranged around the launch tube 21 to strengthen the corner strength of the launch tube 21 and resist the stress concentration effect of the inner chamfer of the launch tube 21.

[0038] In some alternative embodiments, a pressure-stabilizing groove 233 is provided on the side of the piston 23 facing the sealing cavity 30. The pressure-stabilizing groove 233 is arranged in the middle of the piston 23, and a flexible pull rope 232 is connected to the middle of the pressure-stabilizing groove 233. When gas rushes into the pressure-stabilizing groove 233, the gas pressure acts on the side wall of the pressure-stabilizing groove 233, and the direction of the gas pressure is perpendicular to the guiding direction of the launching tube 21. This allows the piston 23 to be stably attached to the inner wall of the launching tube 21 and is not easy to shake. This ensures that the middle of the piston 23 is stably subjected to gas pressure. Moreover, the pressure-stabilizing groove 233 also helps to reduce the weight of the piston 23.

[0039] The launch tube 21 is detachably mounted on the mounting body 10 by multiple screws, which facilitates quick replacement of the launch tube 21.

[0040] A cavity is formed inside the mounting body 10, and the launching tube 21 is arranged inside the cavity. An opening is provided at the top of the cavity, and a top cover 40 is hinged to the top of the mounting body 10. The top cover 40 is used to close the opening.

[0041] The bottom of the mounting body 10 is also connected to a base 50. The base 50 and the support 60 are rotatably engaged. A hydraulic lifting system 80 is provided between the base 50 and the support 60. The hydraulic lifting system 80 lifts the base 50, causing the base 50 and the mounting body 10 to swing up and down, thereby adjusting the vertical angle of the launch tube 21. A disc 70 is provided at the bottom of the support 60. The disc 70 is fixed to the accompanying launch vehicle, facilitating the movement of the folding-wing UAV swarm launch device. The support 60 and the disc 70 are rotatably engaged, allowing the support 60 to adjust its horizontal angle relative to the disc 70.

[0042] The drive mechanism that drives the support base 60 to rotate relative to the disk 70 can be selected according to actual needs. In this embodiment, the drive mechanism includes a steering rocker arm 90 and a transmission gear set. The steering rocker arm 90 is rotatably mounted on the support base 60 and is driven to the disk 70 through the transmission gear set. By rocking the steering rocker arm 90, the support base 60 and the disk 70 can rotate relative to each other. Of course, the structure of the drive mechanism is not limited to this. Those skilled in the art can also select other suitable structures according to the teachings of this invention. For example, the support base 60 and the disk 70 can be driven to rotate relative to each other by a drive motor. This example is not limited to this one.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
