Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle bombing, in particular to an unmanned aerial vehicle and a bombing device thereof. Background Art

[0002] As a new type of combat equipment, drone weapon systems play an increasingly important role in wars, fundamentally changing the way of warfare and profoundly affecting the mode of modern warfare. Modern warfare has become a "non-contact" and "networked" high-tech war, so countries around the world have made the development of drone weapons a priority.

[0003] In recent years, urban combat has become more and more common. Although large drones have advantages such as long endurance and powerful weapons, they are large in size, expensive, and require long-term training for professionals to operate. Their main targets are large enemy combat equipment, base stations, or personnel clusters. In the trend of modern battlefields increasingly leaning towards counter-terrorism operations, special operations, guerrilla warfare, and small-scale operations, the advantages of large drones are obscured by the complex battlefield environment. The advantages of small rotor drones are small size, flexible movements, low cost, and simple operation. Small rotor drones equipped with bomb droppers can attack local personnel targets at a slightly longer distance, provide fire support, or perform dangerous tasks. For modern battlefields, this just fills the firepower gap between ground combat and air support.

[0004] However, the bomb droppers on existing drones are mostly complex in design. They are large in size and costly. In addition, the bombs are too complicated to install and cannot respond in time when bombs are needed, making them unsuitable for individual combat personnel to carry. Utility Model Content

[0005] The purpose of the utility model is to provide a drone and a bomb launcher thereof, which can at least solve some of the defects in the prior art.

In this embodiment, the adapter assembly 2 can be composed of two parts, wherein the pylon 20 can be conveniently detachably connected to the fuselage of the drone, and the adapter frame 21 can be conveniently detachably connected to the pylon 20, so that it is more convenient during assembly. Preferably, the adapter frame 21 includes a T-shaped slider 210, and the pylon 20 includes a slide groove 200 for the T-shaped slider 210 to slide into, and the T-shaped slider 210 is clamped with the slide groove 200, and the detachable connection method adopts the method that the T-shaped slider 210 slides into the slide groove 200, and the T-shaped slider 210 can be hung in the slide groove 200 of the pylon 20. When the clamping force is increased, the T-shaped slider 210 can be firmly connected with the slide groove 200. Preferably, in order to further ensure the stable connection between the T-shaped slider 210 and the slide 200, a locking hole 201 may be provided on the bracket 20, and a locking screw for locking the T-shaped slider 210 in the slide 200 is installed in the locking hole 201, and the locking screw may be manually screwed into the locking hole 201. Of course, in addition to this detachable connection method, screw connection is also feasible or other existing detachable connection methods are all possible, and this embodiment does not limit this. Preferably, the adapter 21 adopts a cavity-type skeleton structure, which can reduce weight. At the same time, the adapter 21 is made of aluminum alloy material and has high strength. In order to further improve the strength, a second reinforcing rib 212 can be designed to strengthen the structural strength. Preferably, a mounting column 203 is provided on the side of the bracket 20 away from the adapter 21, and a connecting hole is provided in the mounting column 203, and a screw 204 that can be connected to the fuselage of the drone is threadedly connected in the connecting hole. In this embodiment, the bracket 20 is connected to the fuselage of the UAV through the mounting column 203, specifically, the connection between the two is achieved by screwing screws into the fuselage of the UAV and the connecting hole. Of course, in addition to this, other existing detachable connection methods are also feasible, and this embodiment does not limit this. Preferably, the bracket 20 has a hollow window 205. The design of the hollow window 205 can reduce the weight of the bracket 20. In order to ensure the rigidity of the bracket 20, the bracket 20 can be made of aluminum alloy, and the first reinforcing rib 206 is designed to strengthen the rigidity of the bracket 20, but the weight can be reduced to ensure the payload of the UAV.

There are two mounting holes on the waist of the servo, which is connected to the middle ring 13 of the delivery tube 1 by screws. One end of the steering plate 31 is connected to the servo by a spline and screwed, and the other end is connected to the locking pin 30 by two screws. After the servo is powered on and receives the command, it can rotate along the output shaft of the servo within a certain angle range, thereby driving the locking pin 30 to insert or pull out the projectile. After the projectile is inserted, the ammunition is locked in the delivery tube 1, realizing the loading and locking of the ammunition. After the projectile is pulled out, the ammunition slides out of the delivery tube 1 under the action of gravity to achieve the purpose of delivery.

[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The utility model provides a drone, including a fuselage and the drone bomb dropper, wherein the adapter assembly 2 is mounted on the fuselage. In this embodiment, the drone bomb dropper is used on the drone to improve the efficiency of drone bomb assembly, with a compact structure, simple mechanism, quick assembly and disassembly, convenient operation, light weight, low cost, and can meet the requirements of multiple bomb loading and delivery. The size and weight of the equipment are suitable for single-soldier combat carrying, and has good use value and application prospects.

The bomb is manually loaded into the delivery tube 1 of the bomb launcher and locked using the locking pin 30 of the bomb locking mechanism 3. Inserting the pin into the bomb body can lock the bomb, and pulling out the pin can realize the bomb delivery. Controlling the action of a single pin or multiple pins can realize the function of sequential or simultaneous delivery of bombs.
