Description

Technical Field

[0001] This invention relates to the field of drone delivery equipment technology, specifically to a drone-borne missile and aerial delivery device. Background Technology

[0002] Currently, the delivery devices for small bombs or fragmentation munitions using various small UAVs as platforms mainly employ probe-firing or dedicated canister-type delivery systems. These delivery systems have the following problems: firstly, they are not reusable and do not meet the delivery requirements of most munitions; secondly, their large size and weight prevent them from achieving universal applicability after changing the projectile diameter. Therefore, designing a reusable bomb-carrying and delivery device with universal mounting requirements is of great significance for advancing the development of the delivery system industry. Summary of the Invention

[0003] The purpose of this invention is to provide a drone-borne missile and aerial delivery device, which can at least solve some of the defects in the prior art.

[0004] To achieve the above objectives, the technical solution of the present invention is a drone-borne missile-carrying and aerial delivery device, comprising a base, a guide tongue, claws, and a linkage drive mechanism. At least one pair of claws are provided below the base, the outer ends of the tops of the claws are rotatably connected to the bottom of the base, and the inner ends of the tops of the claws are connected to the linkage drive mechanism for driving the claws to open and clamp relative to each other. A guide tongue for positioning the missile is installed on the bottom surface of the base.

[0005] As one implementation method, the inner sides of the tops of the two claws of each pair of claws are connected by a spring.

[0006] As one embodiment, the linkage drive mechanism includes an inverted Y-shaped rod, a bent rod, and a drive assembly for driving the inverted Y-shaped rod to move in a vertical direction. The inverted Y-shaped rod includes a main rod and two branch rods connected to the bottom of the main rod. The top of the main rod is connected to the drive assembly, and the two branch rods are respectively connected to the inner ends of the tops of the two claws through two bent rods.

[0007] As one embodiment, the bending rod includes a vertical section and an inclined section connected to the top of the vertical section. The bottom of the vertical section is connected to the top of the claw. The inclined section is in the same inclination direction as the forked rod and is connected to the forked rod.

[0008] As one embodiment, the base is provided with a guide block, the guide block is provided with a guide hole that runs vertically through the base, and the top of the main rod runs through the guide hole upward and is connected to the drive assembly.

[0009] As one embodiment, the drive assembly includes a straight connecting rod and a push rod for pushing the straight connecting rod to move in a vertical direction. The two ends of the straight connecting rod are respectively connected to the drive end of the push rod and the top of the main rod by a hinge.

[0010] As one embodiment, a guide shaft is fixed on the base, and a linear bearing is installed on the straight connecting rod, with the linear bearing cooperating with the guide shaft.

[0011] As one implementation method, the top of the guide tongue is provided with a limiting step to restrict the translation and rotation of the projectile.

[0012] As one embodiment, a support lug is provided on the bottom surface of the base, and the outer end of the top of the support claw is hinged to the support lug.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention restricts the rotation and upward translation of the projectile using a guide tongue, and restricts the downward translation of the projectile using a pair of claws to achieve the clamping requirement. A linkage drive mechanism drives the pair of claws to rotate around the base, causing the pair of claws to open or clamp relative to each other, thereby achieving the clamping, lifting, and release of the slot at the tail of the projectile to perform the task of transporting and deploying the projectile. After physical verification, the linkage drive mechanism has smooth movement, small space occupation, and small initial thrust required to meet the clamping and deployment conditions. The device has high reliability and can be reused, while also meeting the requirements for universal mounting. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0024] like Figures 1-3 As shown, this embodiment provides a UAV ordnance loading and air-drop device, including a base 1, a guide tongue 12, claws 13, and a linkage drive mechanism. At least one pair of claws 13 are provided on the lower part of the base 1. The claw pair is used to provide clamping force, lifting force, and release force for the ordnance, and is the execution terminal for the ordnance clamping and dropping actions. The outer end of the top of the claw 13 is rotatably connected to the bottom of the base 1, and the inner end of the top of the claw 13 is connected to the linkage drive mechanism. The linkage drive mechanism is used to drive the claw pair to open and clamp relative to each other, and is the driving end for realizing the ordnance clamping and dropping actions. An interface for installing the guide tongue 12 is provided on the bottom surface of the base 1. The guide tongue 12 is installed on the base 1 through this interface. The guide tongue 12 is located between the two claws 13 of the claw pair. The protruding part of the guide tongue 12 forms a mating relationship with the tail of the ordnance, thereby performing initial positioning of the ordnance.

[0025] In this embodiment, the linkage drive mechanism drives the claws to clamp or open relative to each other, thereby gripping, lifting, and releasing the tail slot of the projectile, realizing the clamping or deployment of the projectile. At the same time, the guide tongue 12 positions the projectile. The device has high reliability and can meet the deployment requirements of most munitions. Moreover, the linkage drive mechanism can drive the claws to repeatedly perform clamping or deployment, making the device reusable and reducing costs. Meanwhile, the claws 13 can rotate around the base 1 and can cooperate with the tail slots of projectiles of different diameters, meeting the requirements for universal mounting.

[0026] The base 1, claw 13, and guide tongue 12 can all be formed from sheet metal, including but not limited to aluminum alloy. All claw pairs can share a single linkage drive mechanism, or each claw pair can use its own linkage drive mechanism. Ideally, the top of the guide tongue 12 is provided with a limiting step to restrict the translation and rotation of the loaded projectile.

[0027] Furthermore, the inner sides of the tops of the two claws 13 of each pair of claws are connected by a spring 11. When the linkage drive mechanism drives the claw pair to clamp relative to each other, the spring 11 can provide a certain gripping force to the claw pair, so that the claw pair can better hold the loaded projectile. Specifically, the spring 11 can be a general-purpose helical spring.

[0028] Specifically, such as Figure 1 As shown, the linkage drive mechanism includes an inverted Y-shaped rod 9, a bent rod 10, and a drive assembly for driving the inverted Y-shaped rod 9 to move vertically. The inverted Y-shaped rod 9 includes a main rod and two branch rods connected to the bottom of the main rod. The top of the main rod is connected to the drive assembly. The two branch rods are respectively connected to the inner ends of the tops of the two claws 13 through the two bent rods 10. The drive assembly is connected to the L-shaped linkage through the inverted Y-shaped rod 9, and the bent rod 10 moves along a predetermined motion trajectory. The inverted Y-shaped rod 9 and the bent rod 10 can be formed from sheet metal, including but not limited to aluminum alloy.

[0029] As one embodiment, the bending rod 10 includes a vertical section and an inclined section connected to the top of the vertical section. The bottom of the vertical section is connected to the top of the claw 13, which drives the claw 13 to move along a predetermined motion trajectory. The inclined section is in the same direction as the forked rod and is connected to the forked rod. The bending rod 10 is connected to the inverted Y-shaped rod 9 and the claw 13 through a connecting pin 6 and a nut 7. One end of the connecting pin 6 has a polygonal head with a smooth shaft in the middle, and the other end is a threaded end with a through hole. Its function is to connect the bending rod 10 with the inverted Y-shaped rod 9 and the claw 13 and to prevent the nut 7 from coming out. The nut 7 is a general-purpose hexagonal nut, which restricts the axial movement of the rod.

[0030] In an optimized embodiment, a cavity is provided in the middle of the base 1. A guide block 8 is fixed inside the cavity by screws. The guide block 8 has a guide hole that extends vertically. The top of the main rod of the inverted Y-shaped rod 9 extends upward through the guide hole and connects to the drive assembly. The outer side of the main rod of the inverted Y-shaped rod 9 mates with and contacts the inner side of the guide hole. The guide block 8 and the guide hole restrict the degree of freedom of the inverted Y-shaped rod 9, allowing it to only perform vertical linear movement. The guide block 8 can be formed from sheet metal, including but not limited to aluminum alloy.

[0031] As one implementation method, the drive assembly includes a straight connecting rod 3 and a push rod 2. The push rod 2 is used to push the straight connecting rod 3 to move vertically. The drive end of the push rod 2 is connected to one end of the straight connecting rod 3 through a connecting pin 6 and a nut 7. The other end of the straight connecting rod 3 is connected to the top of the main rod of the inverted Y-shaped rod 9 through the connecting pin 6 and the nut 7. The push rod 2 drives the inverted Y-shaped rod 9 to move vertically through the straight connecting rod 3, thereby driving the two claws 13 to rotate to achieve relative opening and clamping for clamping and releasing the loaded projectile. Among them, the push rod 2 is an integrated linear motion device, including but not limited to an electric push rod 2 and a hydraulic rod. The fixed seat of the push rod 2 is connected to one side of the seat body 1 by screws. The function of the straight connecting rod 3 is to drive the inverted Y-shaped rod 9 to perform linear motion. It can be made of sheet metal including but not limited to aluminum alloy material, with local weight reduction grooves and a reserved interface for mounting a linear bearing 4 at the top.

[0032] In the optimized embodiment, a vertically arranged guide shaft is fixed to one side of the base 1. A linear bearing 4 is fixed to the straight connecting rod 3 by screws. The linear bearing 4 is the intermediate transition link between the push rod 2 and the inverted Y-shaped rod 9. The linear bearing 4 slides with the guide shaft to prevent jamming and ensure that the straight connecting rod 3 moves linearly together with the push rod 2. The guide shaft includes, but is not limited to, a circular guide shaft and a polygonal guide shaft.

[0033] like Figure 1 As shown, a lug 16 is provided on the bottom surface of the base 1. The outer end of the top of the claw 13 is hinged to the lug 16. The linkage drive mechanism drives the top of the claw 13 to rotate around the lug 16, thereby clamping, lifting, and releasing the slot at the tail of the payload. Optimally, the top of the base 1 is also provided with an interface for installing a support adapter plate 5. The support adapter plate 5 is fixed to the base 1 through this interface, enabling the connection between the base 1 and the UAV body. The support adapter plate 5 can be formed from sheet metal, including but not limited to aluminum alloy, and the support adapter plate 5 and the base 1 can be connected by countersunk screws.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
