Description

Technical Field

[0001] This utility model relates to the field of drone bombing technology, specifically an automatic drone bomber. Background Technology

[0002] With the rapid development of drone technology, drones have been applied to a wide range of fields, such as emergency rescue, forest search and rescue, road management, disaster relief, and express delivery. Drones, with their speed and flexibility, have brought higher productivity and work efficiency to society.

[0003] Meanwhile, people's functional requirements for drones are constantly being improved and enhanced. This includes the need for drones to drop bombs, such as the need for drones with automatic dropping capabilities to drop fire extinguishing bombs into fire scenes during firefighting and rescue operations. Existing bomb droppers come in various structures, such as strap-on bomb droppers and vertical tube bomb droppers, but some bomb droppers have poor stability. If not operated properly, the bomb may easily fall off during installation or while the drone is in flight, resulting in low safety.

[0004] To address this, we designed and developed a drone bomber that can effectively prevent the projectile from falling out of the launcher. By setting a limiting cover on the front side of the launch tube, the projectile can be effectively prevented from detaching from the launch tube. At the same time, it can realize the vertical launching of the projectile, improve the accuracy of the launch, and eliminate the need for an additional complex projectile limiting structure in the launch tube. The structure is simple and novel, the design is scientific and reasonable, and it is highly practical. Utility Model Content

[0005] The purpose of this invention is to provide an automatic bomb dispenser for unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic bomb dispenser for unmanned aerial vehicles includes a main support frame, a bomb dispenser tube, a limiting cover, and a bomb dispenser tube limiting component;

[0009] The bomb-feeding tube limiting component is used to limit the bomb-feeding tube, so that the bomb-feeding tube is horizontally fixed to the lower side of the main support frame. When the bomb-feeding tube limiting component releases the limiting of the bomb-feeding tube, the bomb-feeding tube moves downward around the tail, and the bomb slides out from the discharge port.

[0010] The limiting cover is fixedly installed on the lower front side of the main support frame to prevent the projectile from falling out of the discharge port when the bomb canister is in a horizontal state.

[0011] As a further preferred embodiment of this utility model: the bomb release limiting component includes a servo motor fixedly mounted on the main support frame, the output end of the servo motor being fixedly connected to a limiting head, the upper front end of the bomb release tube being fixedly mounted on a side plate, and the lower end of the side plate having a slot corresponding to the limiting head. When the bomb release tube is in a horizontal state, the limiting head can be locked in the slot.

[0012] As a further preferred embodiment of this utility model: a positioning pin is fixedly provided on the front side of the upper end of the bomb launcher, and a side plate is fixedly provided on the side of the upper end of the positioning pin near the main support frame. An upper positioning plate located above the bomb launcher is fixedly provided on the main support frame. An opening slot is provided on the front side of the upper positioning plate for the positioning pin and the side plate to pass through. A positioning slot corresponding to the positioning pin is provided on the rear side of the opening slot. The rear side of the positioning pin can be inserted into the positioning slot. The servo motor is fixedly provided on the upper positioning plate.

[0014] As a further preferred embodiment of this utility model: a connecting plate is fixedly connected to the upper end of the limiting cover, an outer sleeve is fixedly installed on the connecting plate, the outer sleeve is sleeved on the main support frame and fixedly connected to the main support frame by fastening bolts, and the main support frame is provided with multiple threaded holes corresponding to the fastening bolts.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This automatic bomb dispenser for drones features a simple and novel structure. Through a rationally designed bomb-dispensing tube limiting component, the tube remains horizontal during drone flight. Furthermore, a limiting cover on the front of the tube prevents bombs from detaching, effectively ensuring the stability of the bombs during drone flight. During bombing, simply controlling the servo motor releases the limiting mechanism, allowing the bomb to slide out of the release port as the tube moves downwards, achieving vertical bombing and improving accuracy. The bomb-dispensing tube maintains excellent stability both horizontally and after bombing, without affecting drone flight and ensuring operational stability. The design is scientifically sound and highly practical. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] Please see Figure 1-5 This embodiment provides an automatic bomb dispenser for unmanned aerial vehicles, including a main support frame 1, a bomb dispenser 2, a limiting cover 3, and a bomb dispenser limiting component;

[0025] The bomb-throwing tube 2 is located below the main support frame 1. A discharge port 20 for placing the bomb is provided on the front side of the bomb-throwing tube 2, and the rear end of the bomb-throwing tube 2 is hinged to the rear side of the main support frame 1; specifically, as shown... Figure 1 as well as Figure 3 As shown, a hinge seat 12 is fixedly installed on the rear side of the main support frame 1, and connectors 13 are rotatably connected to both sides of the hinge seat 12. A U-shaped mounting plate 14 is fixedly installed on the rear side of the bomb-throwing tube 2. The inner side of the U-shaped mounting plate 14 is fixedly connected to the two connectors 13. A magnet 18 is fixedly installed on the rear side of the upper end of the U-shaped mounting plate 14. When the rear side of the upper end of the U-shaped mounting plate 14 contacts the rear side of the hinge seat 12 after bomb throwing, the magnet 18 can be attracted to the hinge seat 12. Figure 3 as well as Figure 4 As shown, the rear side of the hinge base 12 can preferably be designed as a slope, so that the U-shaped mounting plate 14 can fit well with the surface of the hinge base 12. The slope design should be a conventional design familiar to those skilled in the art, and will not be described in detail. The design of the magnet 18 can ensure that the tail of the bomb-dropping tube 2 can be attracted to the hinge base 12 after bombing, thereby preventing the bomb-dropping tube 2 from shaking randomly during the flight of the UAV after bombing, which would affect the stability of the UAV flight.

[0026] The bomb release tube limiting assembly is used to limit the bomb release tube 2, fixing it horizontally to the lower side of the main support frame 1. When the bomb release tube limiting assembly releases the limiting assembly, the bomb release tube 2 moves downward around its tail, and the bomb slides out from the discharge port 20; specifically, as shown... Figure 1-3 As shown, the bomb release limiting assembly includes a servo motor 7 fixedly mounted on the main support frame 1. A limiting head 8 is fixedly connected to the output end of the servo motor 7. A side locking plate 9 is fixedly mounted on the upper front side of the bomb release tube 2. A slot 15 corresponding to the limiting head 8 is provided at the lower end of the side locking plate 9. When the bomb release tube 2 is in a horizontal state, the limiting head 8 can be locked in the slot 15. It should be noted that the servo motor 7 is a conventional and universal structure familiar to those skilled in the art, and can be obtained through custom purchase. Furthermore, the shapes of the limiting head 8 and the slot 5 can be customized according to actual needs, as long as the cooperation of the two achieves the limiting and fixing of the side locking plate 9 and the bomb release tube 2. Their shapes are conventional designs familiar to those skilled in the art, and this application will not elaborate further.

[0027] Furthermore, to better ensure the stability of the bomb launcher 2 in a horizontal position, such as Figure 1-3 as well as Figure 5 As shown, a positioning pin 5 is fixedly installed on the front side of the upper end of the bomb launcher 2, as is a conventional design. Figure 1 As shown, by fixing a fixing ring 4 to the front side of the bomb launcher 2, the positioning pin 5 is fixedly set onto the fixing ring 4, thus achieving a fixed connection between the positioning pin 5 and the bomb launcher 2. There are various methods for fixing the fixing ring 4 and the bomb launcher 2, such as snap-fit, bolt connection, etc., which will not be elaborated upon in this application. The side plate 9 is fixedly set on the upper end of the positioning pin 5 near the main support frame 1. An upper positioning plate 6 is fixedly set on the main support frame 1 above the bomb launcher 2. An opening slot 19 is opened on the front side of the upper positioning plate 6 for the positioning pin 5 and the side plate 9 to pass through. A positioning groove 21 corresponding to the positioning pin 5 is opened on the rear side of the opening slot 19, allowing the rear side of the positioning pin 5 to be inserted into the positioning groove 21. The servo motor 7 is fixedly set on the upper positioning plate 6. The upper positioning plate 6 has the following structural shape: Figure 5As shown, the design of the opening slot 19 ensures that the upper positioning plate 6 does not affect the movement of the positioning pin 5 and the side plate 9, while the design of the positioning slot 21 ensures that the bomb-throwing tube 2 is in an accurate horizontal state and guarantees the stability of the bomb-throwing tube 2. As is common knowledge familiar to those skilled in the art, there should not be a large gap between the positioning slot 21 and the positioning pin 5 to avoid the positioning pin 5 from shaking. At the same time, there should not be too much friction between the two to avoid affecting the time when the bomb-throwing tube 2 moves downward to throw bombs after the limit is released. The matching parameters of the positioning slot 21 and the positioning pin 5 should be conventional settings familiar to those skilled in the art, and this application will not elaborate on or limit them further.

[0028] Furthermore, the limiting cover 3 is fixedly installed on the lower front side of the main support frame 1, which is used to prevent the projectile from falling out of the discharge port 20 when the grenade launcher 2 is in a horizontal state. Specifically, as shown... Figure 1-4 As shown, as is common sense, the limiting cover 3 should be on the same central axis as the horizontally positioned bomb launcher 2. A connecting plate 10 is fixedly connected to the upper end of the limiting cover 3, and an outer sleeve 11 is fixedly mounted on the connecting plate 10. The outer sleeve 11 is fitted onto the main support frame 1 and fixedly connected to the main support frame 1 by fastening bolts 16. Figure 2 As shown, multiple threaded holes 17 corresponding to the fastening bolts 16 are provided on the main support frame 1. Through the cooperation of the threaded holes 17, the fastening bolts 16, and the outer sleeve 11, the distance between the limiting cover 3 and the head of the grenade launcher 2 can be adjusted according to the actual length of the projectile head to ensure the stability of the projectile in the grenade launcher 2 and avoid large shaking of the projectile. During adjustment, simply unscrew the fastening bolts 16, adjust the position of the outer sleeve 11 on the front side of the main support frame 1, and then fix the outer sleeve 11 with the fastening bolts 16. This adjustment method should be a conventional spacing adjustment setting familiar to those skilled in the art. Those skilled in the art can also use other conventional limiting and fixing components to achieve the limiting and fixing of the outer sleeve 11 on the main support frame 1. This application will not elaborate on the limitations.

[0029] It should be noted that in practical applications, during drone flight, the missile's nose may slide into the limiting cover 3. If the limiting plate 9 on the opposite side of the limiting latch 8 is directly released, the limiting cover 3 may easily jam the missile, preventing the bomb launcher 2 from moving downwards and thus preventing the bomb release action. Therefore, before actually releasing the bomb, first control the drone to tilt slightly backward, allowing the missile to slide into the bomb launcher 2, ensuring that the front end of the missile leaves the limiting cover 3. Then, return the drone to a horizontal position (the bomb can also be released while tilted). Subsequently, control the servo motor 7. The operation causes the limiting head 8 to rotate, disengaging it from the slot 15 on the side plate 9 and engaging the limiting position on the bomb launcher 2. The bomb launcher 2 and the bomb body, under their own weight, rotate downwards, and the bomb body begins to slide out of the bomb launcher 2. When the rotation reaches a certain angle, the bomb body completely slides out of the bomb launcher 2, completing the bomb launching operation. Simultaneously, due to inertia, the bomb launcher 2 continues to rotate backwards. When the U-shaped mounting plate 14 contacts the hinge seat 12, the magnet 18 attracts the U-shaped mounting plate 14 onto the hinge seat 12, ensuring that the bomb launcher 2 does not wobble after launching the bomb.

[0030] When the device releases the projectile, the projectile is already in a large tilted state when it slides out of the bomb release tube 2, which allows the projectile to quickly return to a vertical state after release. Compared with the horizontal bomb release design, this bomb release method can ensure the accuracy of the bomb release.

[0031] It should be noted that the magnet 18 should have sufficient adsorption force so that the U-shaped mounting plate 14 can drive the rear of the bomb-throwing tube 2 to be stably adsorbed on the hinge seat 12. The selection of the magnet 18 should be common knowledge familiar to those skilled in the art, and this application will not elaborate on the limitation. At the same time, the material of the bomb-throwing tube 2 should also preferably be a lightweight material to ensure that the bomb-throwing tube 2 can be stably magnetically adsorbed on the hinge seat 12 after bombing. It should be noted that the magnet 18 is just a conventional setting familiar to those skilled in the art for limiting the tail of the bomb-throwing tube 2. Those skilled in the art can also use other conventional parts to limit the tail of the bomb-throwing tube 2 after bombing, such as a buckle structure. These should be conventional structural replacements familiar to those skilled in the art, and this application will not elaborate on the limitation.

[0032] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0033] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
