Description

Technical Field

[0001] The invention belongs to the technical field of unmanned aerial vehicle (UAV) throwing, and in particular relates to an unmanned aerial vehicle (UAV) ammunition throwing device. Background Art

[0002] Drones are lightweight, fast, and have precise positioning advantages. They are widely used in various aerial photography and throwing fields. Drones are combined with ammunition throwing technology to enable remote throwing without the operator approaching. They can also be thrown in complex or dangerous environments, effectively reducing throwing costs, improving throwing accuracy, and ensuring the safety of operators. At present, drone ammunition throwing technology has the following problems: (1) The loading and fixing of ammunition is rather complicated, requiring operators to perform precise and complex operations to complete the loading and fixing; (2) During the transportation of ammunition carried by drones, the ammunition is not fixed firmly enough, which may cause the ammunition to loosen or fall off; (3) The operation of throwing ammunition is relatively complicated and requires reliance on a precise control system, which results in a high cost for the throwing device. Summary of the invention

[0003] In view of the above technical problems, the present invention provides an unmanned aerial vehicle ammunition thrower, which creatively designs a double locking component, and adopts a double locking method combining elastic convergence locking and air pressure adsorption locking to restrain and fix the ammunition. In the process of converging the ammunition, the extrusion effect generated by the ammunition itself is used to achieve negative pressure adsorption. The double locking process can be achieved only by relying on the servo to drive the elliptical plate to rotate. While the restraint belt is used to restrain the lower part of the ammunition, the tightening and squeezing effect of the ammunition is used to release the sealing piston plate, thereby automatically achieving negative pressure adsorption, which significantly improves the loading efficiency and the reliability of ammunition fixation.

[0004] The technical scheme adopted by the present invention is as follows: This scheme provides an unmanned aerial vehicle ammunition thrower, which is composed of a detachably connected unmanned aerial vehicle and a thrower, the thrower includes a body connecting plate, a body upper protective cover, a throwing body and a servo, the body connecting plate is detachably connected to the lower wall of the unmanned aerial vehicle, the body upper protective cover is detachably connected to the lower wall of the body connecting plate with a trapezoidal plug-in structure, the throwing body is fixedly connected to the lower wall of the body upper protective cover by screws, the servo is fixedly connected to the side wall of the throwing body, a locking cavity is opened in the lower wall of the throwing body, a double locking assembly is arranged in the locking cavity, the output shaft of the servo is transmission-connected to the double locking assembly, a laser emitter is fixedly arranged on the outer wall of the unmanned aerial vehicle, the laser emitter is located directly above the servo, a photosensor is fixedly arranged on the upper wall of the servo, the photosensor is electrically connected to the servo, and the laser emitter faces the photosensor.

[0005] In this solution, the double-locking component includes a middle partition plate, a sealing piston plate, a converging plate, and a rotating shaft. The middle partition plate is horizontally and fixedly arranged on the inner wall of the locking cavity. The sealing piston plate is slidably and tightly attached to the inner wall of the locking cavity. The sealing piston plate is located above the middle partition plate. The converging plate is slidably arranged on the lower wall of the throwing body. The converging plate is located below the middle partition plate. The rotating shaft is rotatably arranged on the middle partition plate. Both ends of the rotating shaft respectively penetrate through the side wall of the throwing body and extend to the outside of the throwing body. A first bevel gear is coaxially and fixedly connected to the outer end of the rotating shaft. A second bevel gear is coaxially and fixedly connected to the output shaft of the servo motor. The first bevel gear and the second bevel gear are meshed. A through groove is formed through the middle of the middle partition plate. An elliptical plate is fixedly arranged in the middle of the rotating shaft. The elliptical plate is located in the through groove. A first tension spring is fixedly connected between the upper wall of the middle partition plate and the lower wall of the sealing piston plate. A second tension spring is fixedly connected between the lower wall of the middle partition plate and the upper wall of the converging plate.

[0006] As a further preference of this solution, shell slots are symmetrically arranged on both sides of the lower wall of the throwing body. A strip-shaped adsorption hole is opened on the top wall of the shell slot. A rubber ring is fixedly arranged on the bottom wall of the shell slot outside the strip-shaped adsorption hole. An adsorption pipe is connected through between the strip-shaped adsorption hole and the inner top wall of the locking cavity.

[0007] Lock teeth are symmetrically distributed and horizontally slidably arranged on the lower wall of the sealing piston plate. A spring is connected between the opposite ends of the lock teeth. A lock hole is horizontally opened on the inner wall of the throwing body. Both ends of the lock hole respectively penetrate through the side wall of the shell slot and the side wall of the locking cavity. The lock hole is located on the movement path of the lock teeth. A pressing rod is slidably arranged inside the lock hole.

[0008] Furthermore, a converging belt is connected between the lower edge of the side wall of the throwing body and the side wall of the converging plate. Ammunition is detachably installed between the converging belt and the shell slot. The converging belt and the shell slot jointly constrain and fix the ammunition.

[0009] The beneficial effects obtained by the present invention are as follows: (1) The present invention uses a double-locking method combining elastic converging locking and air pressure adsorption locking to constrain and fix the ammunition. During the process of converging the ammunition, the negative pressure adsorption is realized by the extrusion effect generated by the ammunition itself. And the double-locking process only needs to rely on the servo motor to drive the elliptical plate to rotate to achieve. While constraining the lower part of the ammunition with a constraint belt, the tightening and extrusion effect of the ammunition is used to release the sealing piston plate, so as to automatically realize the negative pressure adsorption, significantly improving the loading efficiency and significantly improving the reliability of ammunition fixation; (2) The double-locking component can effectively cope with the loosening situation during the ammunition transportation process through the elastic energy storage method. When there is a slight loosening, the double-locking component can immediately automatically release the elastic potential energy so that the ammunition is locked again; (3) The ammunition throwing process is very simple. Only need to remotely control the laser emitter to control the operation of the servo motor, and then the double-locking component can double-release and loosen the ammunition.

[0013] Embodiment 1: Please refer to Figures 1-9, this embodiment provides a drone ammunition launcher, which is composed of a detachable connection between a drone 1 and a launcher 2. The launcher 2 includes a body connecting plate 21, a body upper cover 22, a throwing body 23 and a servo 24. The body connecting plate 21 is detachably connected to the lower wall of the drone 1. The body upper cover 22 is detachably connected to the lower wall of the body connecting plate 21 in a trapezoidal plug-in structure. The throwing body 23 is fixedly connected to the lower wall of the body upper cover 22 by screws. The servo 24 is fixedly connected to the side wall of the throwing body 23. A locking cavity 231 is formed in the lower wall of the throwing body 23. A laser emitter 11 is fixedly arranged on the outer side wall of the drone 1, and the laser emitter 11 is directly above the servo 24. A photosensitive sensor 241 is fixedly arranged on the upper wall of the servo 24. The photosensitive sensor 241 is electrically connected to the servo 24. The laser emitter 11 is directed towards the photosensitive sensor 241. A restraint belt 230 is connected between the lower edge of the side wall of the throwing body 23 and the side wall of the restraint plate 235. An ammunition 3 is detachably installed between the restraint belt 230 and the cartridge case slot 237. The restraint belt 230 and the cartridge case slot 237 jointly restrain and fix the ammunition 3.

[0014] A double locking assembly 232 is provided in the locking cavity 231. The double locking assembly 232 includes a middle partition plate 233, a sealing piston plate 234, a restraint plate 235 and a rotating shaft 236. The middle partition plate 233 is horizontally and fixedly arranged on the inner wall of the locking cavity 231. The sealing piston plate 234 is slidably and tightly attached to the inner wall of the locking cavity 231. The sealing piston plate 234 is located above the middle partition plate 233. The restraint plate 235 is slidably arranged on the lower wall of the throwing body 23. The restraint plate 235 is located below the middle partition plate 233. The rotating shaft 236 is rotatably arranged on the middle partition plate 233. Both ends of the rotating shaft 236 respectively penetrate through the side wall of the throwing body 23 and extend outside the throwing body 23. A first bevel gear 2361 is coaxially and fixedly connected to the outer end of the rotating shaft 236. A second bevel gear 242 is coaxially and fixedly connected to the output shaft of the servo 24. The first bevel gear 2361 and the second bevel gear 242 are meshed. A through slot 2331 is formed through the middle of the middle partition plate 233. An elliptical plate 2362 is fixedly arranged in the middle of the rotating shaft 236. The elliptical plate 2362 is located in the through slot 2331. A first tension spring 2332 is fixedly connected between the upper wall of the middle partition plate 233 and the lower wall of the sealing piston plate 234. A second tension spring 2333 is fixedly connected between the lower wall of the middle partition plate 233 and the upper wall of the restraint plate 235.

[0015] Cartridge case slots 237 are symmetrically arranged on both sides of the lower wall of the throwing body 23. A strip-shaped adsorption hole 2371 is formed in the top wall of the cartridge case slot 237. A rubber ring 2372 is fixedly arranged on the bottom wall of the cartridge case slot 237 outside the strip-shaped adsorption hole 2371. An adsorption tube 238 is connected in communication between the strip-shaped adsorption hole 2371 and the inner top wall of the locking cavity 231.

[0016] On the lower wall of the sealed piston plate 234, locking teeth 2341 are symmetrically and horizontally slidably arranged. A spring 2342 is connected between the ends of the opposite locking teeth 2341. Horizontally, a locking hole 239 is formed in the inner wall of the throwing body 23. Both ends of the locking hole 239 penetrate the side wall of the cartridge case slot 237 and the side wall of the locking cavity 231 respectively. The locking hole 239 is located on the movement path of the locking teeth 2341. On the upper wall of the end of the locking teeth 2341 close to the locking hole 239, a wedge surface is provided. Inside the locking hole 239, a pressing rod 2391 is slidably arranged. One end of the pressing rod 2391 close to the cartridge case slot 237 is provided as an inclined surface, and the inclination angle of this inclined surface is the same as the inclination angle of the cartridge case slot 237 at this position, so as to be able to fit with the outer wall of the ammunition 3. When the ammunition 3 is in contact with the cartridge case slot 237, it will push the pressing rod 2391 to slide. At this time, one end of the pressing rod 2391 close to the locking teeth 2341 is exactly flush with the inner side wall of the locking cavity 231 vertically. This can not only ensure that the pressing rod 2391 can smoothly push the locking teeth 2341 out of the locking hole 239, but also prevent the pressing rod 2391 from jamming the locking teeth 2341 and the sealed piston plate 234.

[0017] The locking hole 239 and the pressing rod 2391 adopt Figure 7 the structural design in, that is, the locking hole 239 limits the pressing rod 2391. The pressing rod 2391 can slide in the locking hole 239 and will not completely slide out of the locking hole 239.

[0018] When this embodiment is specifically used, it includes the following processes: loading ammunition, flying and transporting, and dropping bombs.

[0019] The ammunition loading process is as follows: In the initial state, the major axis of the elliptical plate 2362 is in the horizontal state. The operator controls the laser emitter 11 to emit laser. The photosensitive sensor 241 receives the laser signal and controls the operation of the servo 24, driving the bevel gear two 242 to rotate, so that the bevel gear one 2361 rotates 90 degrees. The bevel gear one 2361 drives the rotating shaft 236 and the elliptical plate 2362 to rotate 90 degrees. During this process, the major axis of the elliptical plate 2362 gradually changes from the horizontal state to the vertical state. The elliptical plate 2362 gradually contacts the sealed piston plate 234 and the converging plate 235, and pushes the sealed piston plate 234 upward and the converging plate 235 downward. The first tension spring 2332 and the second tension spring 2333 are stretched. During the upward sliding of the sealed piston plate 234, the locking teeth 2341 are driven to move. When the sealed piston plate 234 moves to the highest position, the locking teeth 2341 reach the locking hole 239. Under the elastic force of the spring 2342, the locking teeth 2341 will snap into the locking hole 239 and push the end of the pressing rod 2391, so that the other end of the pressing rod 2391 protrudes from the cartridge case slot 237. At this time, the space between the restraint belt 230 and the cartridge case slot 237 is relatively loose, facilitating the placement of the ammunition 3; The operator takes two ammunitions 3 and places them respectively between the constricting belts 230 on both sides and the cartridge case slots 237. Then, the operator controls the servo 24 to run in the reverse direction to reset through the laser emitter 11, so that the elliptical plate 2362 rotates reversely by 90 degrees, that is, the long axis of the elliptical plate 2362 gradually rotates to the horizontal state. During this process, the sealing piston plate 234 is temporarily locked and unable to move because the locking teeth 2341 are engaged in the locking holes 239, while the second tension spring 2333 first contracts and drives the constricting plate 235 to move upward, so that the constricting belts 230 gradually wrap and tighten the ammunition 3. As the ammunition 3 is tightened, the outer wall of the ammunition 3 gradually clings to the cartridge case slots 237, and the outer wall of the ammunition 3 also clings to the rubber ring 2372 on the outer periphery of the strip-shaped adsorption holes 2371, blocking the outer end of the strip-shaped adsorption holes 2371. The outer wall of the ammunition 3 will gradually push the extrusion rod 2391, causing the extrusion rod 2391 to move towards the locking teeth 2341 and gradually pushing the locking teeth 2341 out of the locking holes 239. When the locking teeth 2341 leave the locking holes 239, the sealing piston plate 234 is no longer restricted, and the pulling force of the first tension spring 2332 causes the sealing piston plate 234 to slide downward, so that the air pressure inside the locking cavity 231 above the sealing piston plate 234 suddenly decreases, and the air pressure in the strip-shaped adsorption holes 2371 suddenly decreases through the connection of the adsorption pipe 238, so as to be able to assist in adsorbing and locking the outer wall of the ammunition 3, further improving the firmness of the ammunition 3.

[0020] The flight transportation process is as follows: The unmanned aerial vehicle 1 flies, driving the launcher 2 to fly, so as to conduct flight transportation on the ammunition 3. During this process, the first tension spring 2332 and the second tension spring 2333 are continuously in a stretched state, that is, the first tension spring 2332 and the second tension spring 2333 are in a continuous energy storage state. If flight bumps cause looseness between the ammunition 3 and the cartridge case slots 237, the pulling force of the second tension spring 2333 can cause the constricting plate 235 to drive the constricting belts 230 to quickly tighten the ammunition 3, and the first tension spring 2332 can also continue to contract, so that the locking cavity 231 and the strip-shaped adsorption holes 2371 adsorb and lock the ammunition 3 again.

[0021] The bomb dropping process is as follows: After the unmanned aerial vehicle 1 reaches the airspace above the designated location, it starts the bomb dropping operation. The operator remotely controls the laser emitter 11 to emit laser light, controls the servo 24 to run, so that the elliptical plate 2362 rotates by 90 degrees, and pushes the sealing piston plate 234 upward and the constricting plate 235 downward. The sealing piston plate 234 moves upward, increasing the air pressure in the locking cavity 231 and the strip-shaped adsorption holes 2371. The strip-shaped adsorption holes 2371 no longer conduct negative pressure adsorption on the ammunition 3. The constricting plate 235 moves downward, driving one end of the constricting belts 230 to move, so that the constricting belts 230 become loose from the ammunition 3. At this time, both the upper and lower sides of the ammunition 3 become loose, and under the action of the wind, the ammunition 3 automatically falls off to complete the dropping. After the dropping is completed, the unmanned aerial vehicle 1 drives the launcher 2 to return for the next dropping operation.

[0022] Example 2: As Figure 10 shown, the difference between this embodiment and the first embodiment is that in this embodiment, three strip-shaped adsorption holes 2371 are provided in one cartridge case slot 237, and the three strip-shaped adsorption holes 2371 are respectively communicated with the adsorption tube 238. By providing the three strip-shaped adsorption holes 2371, the outer wall of the ammunition 3 can be more reliably adsorbed and fixed.
