Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to a unmanned aerial vehicle bomb launching device. BACKGROUND

[0002] The current unmanned aerial vehicle bomb launching mainly has two ways of gravity air drop or pre-press spring ejection. When gravity air drop is adopted, the aerial bomb is freely placed in the cabin, and flight vibration can easily cause the deviation of the fuze mechanism or even accidental triggering explosion. Meanwhile, the drop point accuracy cannot be controlled, and it is difficult to meet the demand of accurate attack. Although the spring ejection device can accurately control the drop point accuracy, it needs to be kept in high-pressure energy storage state for a long time. If the task is cancelled, the aerial bomb needs to be disassembled, and the sudden release of the pre-press spring energy can easily cause personnel casualties. In particular, there is lack of safety conversion mechanism for "launching-standby" state, and once the launching process is started, it is irreversible, which cannot adapt to the changing battlefield environment. Moreover, the fuze is directly exposed during the transportation, flight, disassembly and landing of the aerial bomb, and collision or friction can cause accidents.

[0023] Referring to Figure 1 The embodiment discloses a UAV bomb-throwing device, which comprises a hanging plate 1, a turnover assembly 2 and an aerial bomb magazine assembly 3.

[0024] The hanging plate 1 is a rectangular flat plate structure, and the hanging plate 1 is provided with mounting through holes 11 corresponding in number and position to the aerial bomb magazine assembly 3. In the embodiment, four mounting through holes 11 are arranged in a rectangular array, and a cover plate (not shown in the figure) is arranged on each mounting through hole 11 to cover the aerial bomb magazine assembly 3. The top of the hanging plate 1 is provided with two groups of hanging ears 12 for connecting with the UAV, and the bottom is provided with two groups of supporting feet 13 for supporting the UAV bomb-throwing device.

[0025] Referring to Figure 2The turnover assembly 2 comprises a lifting structure 21 and a multi-claw connecting rod 22. The fixed end of the lifting structure 21 is fixed on the hanging plate 1 between the four mounting through holes 11, and the output end is connected with the multi-claw connecting rod 22. The multi-claw connecting rod 22 is provided with four claw ends away from the lifting structure. Each claw end is hingedly connected with a group of the aerial bomb magazine assemblies 3. It should be noted that the lifting structure 21 is a rigid chain lifting mechanism that can be purchased in the market. The chain of the rigid chain lifting mechanism is composed of high-strength alloy chain links, can be curled and stored, and when stretched, the chain links are interlocked to form a rigid column, which can not only transmit tension but also bear thrust, thereby realizing stable lifting.

[0026] The multi-claw connecting rod 22 is composed of one vertical rod 221 and two horizontal rods 222. One end of the vertical rod 221 is connected with the output end of the lifting structure 21 through the hanging plate 1, and the other end is arranged away from the bottom end face of the hanging plate 1 and is horizontally connected with two horizontal rods 222 on both sides of the end. Two ends of each horizontal rod 222 are hingedly connected with a group of the aerial bomb magazine assemblies 3.

[0027] Each group of the aerial bomb magazine assemblies 3 is hingedly connected with the bottom of the hanging plate 1 at one end and with the end of the horizontal rod 222 at the other end. When the aerial bomb magazine assemblies 3 are not turned over, the launch ports thereof are arranged in the direction of the mounting through holes 11 on the hanging plate 1.

[0028] Referring to Figures 3 to 5 The aerial bomb magazine assembly 3 comprises a magazine seat 31, a bomb launching barrel 32, an aerial bomb magazine body 33, an elastic locking structure 34, a launching structure 35 and a rocker structure 36.

[0029] The magazine seat 31 is a square tube structure with an opening at the top. The square tube structure is composed of a bottom plate, a front plate, a rear plate, a left side plate and a right side plate. The end of the horizontal rod 222 is hingedly connected with the top of the rear plate. A cam slide plate 311 is further arranged in the interior of the magazine seat 31.

[0030] Inside the chamber 31 above the cam slide plate 311, there is a bomb drop tube 32 with openings at the top and bottom. The top opening of the bomb drop tube 32 is flared and faces the mounting through hole 11 on the hanging plate 1. Two first guide holes 321 are symmetrically arranged on the bomb drop tube 32. Each first guide hole 321 extends from the cylindrical body of the bomb drop tube towards the flared body. Inside the bomb drop tube 32, there is a bomb bay body 33 for installing the bomb 4. The top of the bomb bay body 33 is open and the bottom is sealed. Two sets of elastic locking mechanisms for locking the bomb 4 are symmetrically arranged in the direction of the opening of the bomb bay body 33. The launch structure 35 is located inside the bomb bay. The launch end of the launch structure 35 is connected to the bomb bay body 33. One end of the rocker structure 36 is hinged to the launch structure 35, and the other end is hinged to the bottom of the hanging plate 1, so that the flipping assembly 2, the bomb bay 31, the launch structure 35 and the rocker structure 36 form a crank-connecting rod mechanism on the hanging plate 1. Specifically, the driving lifting structure 21 drives the multi-claw connecting rod 22 to move down, which in turn drives the bomb bay 31 to rotate on the rocker structure 36 until the top opening of the bomb bay 31 rotates away from the mounting through hole 11, so as to realize the launch of the bomb 4 on the bomb bay body 33.

[0031] See Figure 5 The elastic locking structure 34 includes an elastic locking rod 341, a locking block 342, and a limiting block 343. One end of the locking rod 341 is connected to the bomb bay body 33, and the other end extends along the axial direction of the bomb bay body 33 and connects to the locking block 342 and the limiting block 343. The locking block 342 and the limiting block 343 are arranged back to back. The locking blocks 342 on the two sets of elastic locking structures 34 are arranged opposite to each other to lock the bomb 4. The limiting block 343 has an "I"-shaped horizontal cross section and is used to engage with the first guide hole 321, so that the limiting block 343 can slide along the setting direction of the first guide hole 321. Specifically, when the bomb 4 is placed in the bomb bay body 33, the elastic locking rod 341 will... The automatic outward expansion ensures that the bomb 4 smoothly enters the bomb magazine body 33. After the bomb 4 is fully inside the bomb magazine body 33, the elastic locking rod 341 will automatically move closer to the bomb 4 and clamp and fix the bomb 4 through two sets of symmetrical locking blocks 342. When the bomb magazine body 33 moves towards the flare of the bomb release tube 32, it drives the limiting block 343 to move on the first guide hole 321. When the limiting block 343 moves to the flare position of the bomb release tube 32, the limiting block 343 expands outward following the setting position of the first guide hole 321, thereby driving the two sets of symmetrical locking blocks 342 to expand outward, so that the bomb 1 is launched from the bomb magazine body 33 and the bomb release operation is completed.

[0032] Furthermore, the side of the locking block 342 away from the locking rod 343 is a curved surface, which matches the curved surface of the bomb 4 at the corresponding position, ensuring that the two sets of locking blocks 342 can clamp the bomb 4.

[0033] See Figure 3 and Figure 4 The launching structure 35 includes a cam 351, a push rod 352, a roller 353, a launching spring 354, and an electromagnetic locking structure 355. The cam 351 is rotatably mounted inside the chamber 31 below the cam slide plate 311 via a rotating shaft. The rotation center of the cam 351 is connected to the rocker arm structure 36. The push rod 352 is vertically telescopically mounted on the cam slide plate 311. One end of the push rod is equipped with a roller 353 that cooperates with the cam 351, and the other end is a telescopic end that is located above the cam slide plate 311 and connected to the bottom of the bomb chamber body 33. The launching spring 354 is sleeved on the push rod 352 between the cam slide plate 311 and the bomb chamber body 33. The rotation of the cam 351 drives the push rod 352 to move vertically, thereby driving the launching spring 354 to move telescopically. Two sets of electromagnetic locking structures 355 fixed on the upper surface of the cam slide plate 311 are used to electromagnetically lock the bomb chamber body 33.

[0034] The electromagnetic locking structure 355 includes a locking frame 3551, an electromagnet 3552, a locking pin 3553, a locking spring 3554, a locking shaft 3555, a locking block 3556, and a locking slider 3557. The locking frame 3551 is fixed to the upper end face of the cam slide plate 311, the electromagnet 3552 is fixed to the locking frame 3551, and the locking pin 3553 is horizontally slidable on the locking frame 3551. For details, please refer to [reference needed]. Figure 6 and Figure 7 The locking pin 3553 consists of a square pin portion 35531, a cylindrical pin portion 35532, a limiting portion 35533, and a notch portion 35534. The square pin portion 35531 is connected to the limiting portion 35533 via the cylindrical pin portion 35532. The end of the limiting portion 35533 away from the cylindrical pin portion 35532 is connected to the notch portion 35534. The locking spring 3554 is sleeved on the cylindrical pin portion 35532 between the square pin portion 35531 and the limiting portion 35533. The locking bracket 3551 has a horizontally provided groove that allows the locking pin 3553 to slide. The part of the groove near the square pin portion 35531 is designed to engage with the square pin portion 35532. The square groove of 35531 limits the sliding of the locking pin 3553, preventing the locking pin 3553 from rotating on the locking frame 3551. The square pin 35531 is squarely positioned close to the electromagnet 3552. When the electromagnet 3552 operates and generates attraction, the square pin 35531 on the locking pin 3553 is attracted to the electromagnet 3552, causing the cylindrical pin 35532, the limiting part 35533, and the cut part 35534 to move squarely towards the electromagnet 3552. The locking spring 3554 is compressed. When the electromagnet is de-energized, the attraction force disappears, and the locking pin 3553 returns to its original position under the elastic force of the locking spring 3554.

[0035] The locking frame 3551 has a vertically arranged insertion hole that communicates with the sliding groove. One end of the locking shaft 3555 is inserted into the insertion hole. The locking shaft 3555 inserted into the insertion hole has, from bottom to top, a slanted groove 35551 and a slot 35552 that can cooperate with the cutout 35534. The other end of the locking shaft 3555 is vertically connected to the locking slider 3557 through the locking block 3556. The bottom of the cylindrical section of the bomb launcher 32 has two second guide holes 322. The locking slider 3557 passes through the second guide holes 322 and is connected to the bomb bay body 33. The second guide holes 322 vertically limit the locking slider 3557. When the electromagnet 3552 is not working, the cutout 35534 on the locking pin 3553 is engaged with the slot 35552. Furthermore, a sliding handle 356 is connected between the locking shafts 3555 on the two sets of electromagnetic locking structures 335.

[0036] See also Figure 1 The rocker structure 36 includes a first rocker 361 and a second rocker 362. The first rocker 361 is hinged to the bottom of the hanging plate 1, and the other end is hinged to the second rocker 362. The end of the second rocker 362 away from the first rocker 361 is rotatably connected to the center of the cam 351.

[0037] Furthermore, it also includes a controller (not shown in the figure) electrically connected to the electromagnet 3552, which controls the energization and de-energization of the electromagnet 3552.

[0038] The working principle of this embodiment is as follows: First, remove the cover plates on the four mounting through holes 11 on the lifting plate 1. Then, place the bomb 4 in the bomb bay body 33 with the tail fins facing down and the fuse facing up. Finally, pull down the sliding handle 356. The locking shaft 3555, locking block 3556, and locking slider 3557 drive the bomb bay body 33 to slide downward in the bomb release tube 32 until the bomb bay body 33 slides to the bottom of the bomb release tube 32. At this time, the locking shaft 3555 is inserted downward into the vertically set insertion hole on the corresponding locking bracket 3551. During the downward movement of the inclined slot 35551 on the locking shaft 3555, it drives... The locking pin 3553 slides backward until the notch 35534 of the locking pin 3553 is engaged in the slot 35552 of the locking shaft 3555 under the action of the locking spring 3554, thus locking the bomb bay body 33. At the same time, during the process of the bomb bay body 33 moving down, the elastic locking rod 341 automatically moves closer to the bomb 4 and clamps and fixes the bomb 4 through two sets of symmetrical locking blocks 342, fixing the bomb 4 in the bomb bay body 33. Then, the cover plate is placed on the mounting through hole 11 on the lifting plate 1, and the lifting lug 12 is connected to the UAV. At this point, the loading of the bomb 1 is completed.

[0039] After the drone is started and enters flight mode, when bombing is required, the lifting structure 2 expands, causing the vertical rod 221 on the multi-claw connecting rod 22 to move downwards, thereby causing the horizontal rod 222 to move downwards. Under the condition of the crank-connecting rod mechanism formed by the first rocker arm 361, the second rocker arm 362, the bomb bay 31, and the cam 351, the bomb bay 31 is flipped, causing the bomb bay assembly 3 mounted on the bomb bay 31 to flip as well, so that the bomb drop tube 32 and the bomb bay body 33 are at a certain launch angle with the ground. At the same time, the cam 351 connected to the second rocker arm 362 rotates, and the roller 353 cooperating with the cam 351 drives the push rod 352 to move vertically, thereby causing the extension end of the push rod 352 connected to the bottom of the bomb bay body 33 to compress, thereby compressing the launch spring 354. If it is necessary to launch bomb 4, the electromagnet 3552 needs to be controlled by the controller. When the square pin 35531 on the locking pin 3553 moves closer to it, the locking pin 3553 releases the locking shaft 3555 from the locking pin 3553. The compressed launch spring 354 drives the bomb bay body 33 to slide from the cylindrical body direction to the flared body direction in the bomb release tube 32. When the bomb bay body 33 slides to the flared position of the bomb release tube 32, the two sets of symmetrical limiting blocks 343 will separate outward along the first guide hole 321 on the flared position of the bomb release tube 32, causing the two sets of symmetrical locking blocks 342 to expand outward, so that the bomb 1 is launched from the bomb bay body 33 under the action of inertia, completing the bomb release operation. If the launch is canceled or after the launch is completed, the driving lifting structure 2 retracts. Under the condition of the crank connecting rod mechanism formed by the first rocker arm 361, the second rocker arm 362, the bay seat 31, and the cam 351, the bay seat 31 is flipped back to the initial position, and the UAV can land normally.

[0040] When bombing is not required and bomb 4 needs to be disassembled, without flipping the bomb bay assembly 3, first control the electromagnet 3552 to be energized via the controller. The square pin 35531 on the locking pin 3553 moves closer to it, releasing the locking pin 3553 from the locking shaft 3555. At the same time, the launching spring 354 has no compression force. Then, the sliding handle 356 is moved upward, causing the bomb bay body 33 to slide upward. The two sets of symmetrical limit blocks 343 will separate outward along the first guide hole 321 on the flare of the bomb release tube 32, causing the two sets of symmetrical locking blocks 342 to expand outward. The bomb 4 can be directly removed from the bomb bay body 33 to complete the disassembly.

[0041] In summary, the UAV bombing device disclosed in this embodiment, through the coordinated control of the flipping component 2 and the bomb bay component 3, ensures that the bomb 4 always maintains an upward fuse attitude during the loading, flight, and disassembly processes. During flight, the fuse of the bomb 4 is sealed inside the bombing tube 32, and the bomb body is fixed by the elastic locking structure 34, isolating it from external impacts and friction, and reducing the risk of accidental triggering. Furthermore, the launch spring 354 of this UAV bombing device has no preload when the bomb 4 is being flown or disassembled, eliminating the risk of accidental release of the pressurized launch spring 354.

[0042] The drone bombing device also supports the drone to abort its mission at any time and land safely, and ensures the directional encapsulation protection of the bomb's fuse throughout its entire process.

[0043] The drone bombing device can also drive multiple bomb bay components 3 to drop bombs simultaneously. By changing the flipping angle of the bomb bay components 3 through the flipping component 2, bombs 4 are launched with a certain initial velocity, forming crossfire. In addition, the drone bombing device is also suitable for timely bombing by drones, landing and lying in wait for bombing, as well as drone bombing experiments and teaching.
