Those skilled in the art will understand the specific meanings of the above terms in this embodiment based on specific circumstances.

[0032] The launcher is an important component of the thrust vehicle system. Its function is to support the target drone and booster, ensuring reliable contact and a fixed launch angle. The existing launcher includes a front leg support assembly, an actuator assembly, a truss body, a rear leg support assembly, and a rear leg support assembly. The actuator assembly and the rear leg support assembly respectively support the head and tail of the target drone. The target drone is launched and taken off using a rocket-assisted launch method, using the thrust generated by the booster to propel the target drone into the air. During the launch and takeoff phase of the target drone, the actuator assembly falls forward to prevent the actuator assembly from scratching the wings and fuselage of the target drone. The truss body is welded from 40*60 mm Q235 square tubes with a wall thickness of 3 mm, and the launcher is an integrated design. The launcher weighs approximately 120 kilograms. When used on a ship, the ship is limited in space and can only accommodate two people to carry the launcher, making it inconvenient to carry and the launch angle is limited. In order to address the above technical shortcomings, a lightweight launcher structure is provided in the embodiment of the utility model.

[0033] The following combination Figure 1 and Figure 2, describing the embodiments of the present utility model.

[0034] According to an embodiment of the present invention, a lightweight launch frame structure is provided, which includes a truss body 100, which extends horizontally from the front side to the rear side and tilts downward; an actuating assembly 200 is provided on the front side of the upper end of the truss body 100, and the actuating assembly 200 is used to support the head of the target drone 300; a first support member 400 is welded and fixedly connected to the rear side of the upper end of the truss body 100, and the first support member 400 is used to support the tail of the target drone 300; a front foot support assembly 500 is detachably connected to the front side of the lower end of the truss body 100, and the front foot support assembly 500 is used to support the ground; a rear foot support assembly 600 is detachably connected to the rear side of the lower end of the truss body 100, and the rear foot support assembly 600 is used to support the ground.

[0035] The launcher structure of this embodiment is fixed to the truss body 100 by welding the first support member 400. Because the first support member 400 does not fall forward (i.e., does not move relative to the truss body 100) during the launch and take-off phase of the target drone 300, the first support member 400 is fixed to the truss body 100 by welding, so the rigidity of the entire launcher structure can be ensured to meet the requirements of assisting the target drone 300 in launching and taking off. In addition, the front leg support assembly 500 and the rear leg support assembly 600 are detachably connected to the front and rear sides of the lower end of the truss body 100, respectively. When the launcher structure of this embodiment is transported, the front leg support assembly 500 and the rear leg support assembly 600 can be disassembled from the truss body 100 so that each part can be separated and detached. It can be transported alone without the need to transport the launcher structure of this embodiment as a whole, thereby facilitating the transport of the launcher structure of this embodiment in a small space on a ship; according to the needs of different launch and take-off angles of the target aircraft 300, different sizes of front leg support assemblies 500 and rear leg support assemblies 600 can be selected to be assembled with the truss body 100, and the truss body 100 of the launcher structure of this embodiment can be adjusted to different inclination angles, so as to meet the needs of different launch and take-off angles on the basis of matching a plurality of different sizes of front leg support assemblies 500 and rear leg support assemblies 600. Compared with purchasing a plurality of launchers with truss bodies 100 with different inclination angles, the cost is lower and less storage space is occupied.

[0036] It should be noted that, because the front foot support assembly 500 and the rear foot support assembly 600 are respectively detachably connected to the truss body 100, when the front foot support assembly 500 or the rear foot support assembly 600 is damaged, the damaged parts can be conveniently removed for repair or replacement, thereby reducing the maintenance cost and difficulty of the launcher structure of this embodiment.

[0037] It can be understood that the horizontal direction is any direction on the horizontal plane, and the vertical direction is a direction perpendicular to the horizontal plane. For the convenience of description, this embodiment uses Figure 1 The horizontal direction and the vertical direction shown in are described as the horizontal direction and the vertical direction, respectively, but should not be understood as a clear limitation to the horizontal direction and the vertical direction.

[0038] like Figure 2 As shown, in some embodiments, the truss body 100 includes a rectangular frame 110, within which a plurality of reinforcing tubes 120 are arranged in a horizontally spaced order. Compared to forming the truss body 100 from a single plate or welding a 40*60 mm, 3 mm thick Q235 square tube to form the truss body 100, this embodiment uses four 40*40 mm, 3 mm thick square tubes spliced ​​and welded in a rectangular shape to form the rectangular frame 110, and multiple 40*40 mm, 3 mm thick square tubes are welded inside the rectangular frame 110 as reinforcing tubes 120. Force analysis has verified that these reinforcing tubes meet strength requirements, thereby controlling the overall weight of the launcher structure of this embodiment to approximately 75 kilograms. This makes the launcher structure of this embodiment more lightweight and more convenient to carry in the confined space of a ship.

[0039] like Figure 1 As shown, in some embodiments, the front leg support assembly 500 extends vertically from the bottom to the top and is tilted backward. Because the target drone 300 moves horizontally from the rear to the front with the assistance of the launcher for takeoff, this embodiment can better absorb the energy generated by the target drone 300 during the takeoff phase by tilting the front leg support assembly 500, thereby ensuring the quality of the target drone 300 during takeoff.

[0040] The detachable connection structure between the truss body 100 and the front foot support assembly 500 is described in detail here. In some embodiments, a first threaded hole is provided on the front side of the lower end of the truss body 100, and a first through hole is formed through the front foot support assembly 500 at a position corresponding to the first threaded hole. The first through hole is for the rod of the first bolt to pass through, and the rod of the first bolt matches the first threaded hole; when the truss body 100 and the front foot support assembly 500 are assembled into one, it is only necessary to align the first through hole with the first threaded hole, and then pass the rod of the first bolt through the first through hole and screw it into the first threaded hole; when the front foot support assembly 500 needs to be disassembled from the truss body 100, it is only necessary to unscrew the rod of the first bolt from the first threaded hole. The connection is tight and easy to assemble and disassemble.

[0041] In another alternative embodiment, a first screw is fixedly connected to the front side of the lower end of the truss body 100, and a second through-hole is formed through the front foot support assembly 500 at a position corresponding to the first screw. When the front foot support assembly 500 is assembled with the truss body 100, the first screw passes through the second through-hole and is threadedly connected to a first nut. Considering that the truss body 100 is welded from a 40*40 mm, 3 mm thick square tube, if threaded holes were machined into the truss body 100, the connection strength would be slightly insufficient. This embodiment connects the truss body 100 to the front foot support assembly 500 by welding a first screw to the truss body 100 and utilizing a threaded connection structure between the first screw and the first nut. This ensures both a secure connection and facilitates assembly and disassembly operations.

[0042] In some embodiments, the rear support assembly 600 is arranged parallel to the vertical direction. Because the target drone 300, with the assistance of the launcher, moves horizontally from the rear to the front during takeoff, relying primarily on the front support assembly 500 to absorb the energy generated, the rear support assembly 600 is arranged vertically in this embodiment. This arrangement does not affect the launch quality of the target drone 300, but also reduces the horizontal space occupied by the launcher structure of this embodiment.

[0043] The detachable connection structure between the truss body 100 and the rear foot support assembly 600 is described in detail here. In some embodiments, a second threaded hole is provided on the rear side of the lower end of the truss body 100, and a third through hole is formed through the rear foot support assembly 600 at a position corresponding to the second threaded hole. The third through hole is for the rod of the second bolt to pass through, and the rod of the second bolt matches the second threaded hole; when the truss body 100 and the rear foot support assembly 600 are assembled into one, it is only necessary to align the third through hole with the second threaded hole, and then pass the rod of the second bolt through the third through hole and screw it into the second threaded hole; when the rear foot support assembly 600 needs to be disassembled from the truss body 100, it is only necessary to unscrew the rod of the second bolt from the second threaded hole. The connection is tight and easy to assemble and disassemble.

[0044] In another alternative embodiment, a second screw is fixedly connected to the rear side of the lower end of the truss body 100, and a fourth through-hole is formed through the rear leg support assembly 600 at a position corresponding to the second screw. When the rear leg support assembly 600 is assembled with the truss body 100, the second screw passes through the fourth through-hole and is threadedly connected to a second nut. Considering that the truss body 100 is welded from a 40*40 mm, 3 mm thick square tube, if threaded holes were machined into the truss body 100, the connection strength would be slightly insufficient. This embodiment connects the truss body 100 to the rear leg support assembly 600 by welding a second screw to the truss body 100 and utilizing a threaded connection between the second screw and the second nut. This ensures both a secure connection and facilitates assembly and disassembly operations.

[0045] In some embodiments, the actuating assembly 200 can be detachably connected to the truss body 100. This arrangement allows the launcher structure of this embodiment to be further disassembled, which is beneficial to reducing the weight of each disassembled part and making it easier to carry the launcher structure of this embodiment in the narrow space on the ship.

[0046] Specifically, the upper end of the truss body 100 is provided with a U-shaped member 130. The U-shaped groove of the U-shaped member 130 accommodates the lower end of the actuating assembly 200. A fifth through-hole is formed through the sidewall of the U-shaped member 130, and a sixth through-hole is formed through the lower end of the actuating assembly 200 at a position corresponding to the fifth through-hole. When the actuating assembly 200 is assembled with the truss body 100, the shank of the third bolt passes through the fifth and sixth through-holes and is threadedly engaged with a third nut. The U-shaped groove's surrounding walls increase the contact area with the lower end of the actuating assembly 200, and the threaded connection between the third bolt and the third nut connects the truss body 100 to the rear leg support assembly 600, ensuring both secure connection and ease of assembly and disassembly.

[0047] In some embodiments, a second support member 700 is detachably connected to the middle portion of the upper end of the truss body 100. The second support member 700 is used to support the rocket booster of the target drone 300. Supporting the rocket booster through the second support member 700 facilitates the rocket booster to generate the thrust to propel the target drone 300 into the air. Furthermore, the detachable connection between the truss body 100 and the second support member 700 allows the launcher structure of this embodiment to be further disassembled, which helps reduce the weight of the disassembled components and facilitates transport of the launcher structure of this embodiment within the confined space of a ship.

[0048] Specifically, the second support member 700 is bolted to the truss body 100 .

[0049] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall all fall within the scope defined by the attached utility model.
