Description

Technical Field

[0001] The present invention relates to the technical field of bomb dropping, and particularly to a drone bomb dropping device and a control method therefor. Background Art

[0002] Drone bomb dropping refers to the act of a drone carrying and dropping explosive weapons for attack. In modern military conflicts, drones are widely used in battlefield reconnaissance, surveillance, and direct combat missions due to their low cost, low risk, and high flexibility. The drone bomb dropping tactic is not limited to large military drones, but even includes modified small commercial or civilian drones, which can carry ammunition, small missiles, or special micro bombs to achieve long-range and precise strikes on ground targets. The application of this flexible and innovative tactic in modern warfare is becoming increasingly prominent.

[0003] When a drone performs a bomb dropping mission, if the amount of ammunition carried is too small, it needs to fly back and forth frequently, reducing the mission execution efficiency and response speed. At the same time, for continuous strike missions, drones with a small amount of ammunition cannot provide sufficient firepower coverage. Especially when dealing with large-scale or scattered targets, it is difficult to form an effective suppression and destruction effect. Once the predetermined strike effect is not achieved and there is not much ammunition, it may lead to the failure of the entire mission. Drones themselves have a certain payload capacity, and loading a small amount means that their transport efficiency is not fully utilized, which is not ideal from an economic efficiency perspective.

[0004] Based on the above situation, the present invention proposes a drone bomb dropping device and a control method therefor that can carry and drop multiple ammunitions at one time. Summary of the Invention

[0005] In order to overcome the drawback of not being able to load a sufficient amount of ammunition according to the load capacity of the drone, the present invention provides a drone bomb dropping device and a control method therefor that can carry and drop multiple ammunitions at one time.

The first sliding frame is vertically slidably connected with a pair of distributed second sliding frames, the second sliding frame is in pressing fit with the adjacent first slider, and a second spring is fixedly connected between the second sliding frame and the adjacent first sliding frame. One end of the second sliding frame away from the first magnet is fixedly connected with a second magnet, and the second magnet is magnetically attracted to the adjacent first magnet on the same side.

[0007] Preferably, the second sliding frame and the adjacent first sliding frame are closed to form an elliptical groove.

[0008] Preferably, it further includes a clamping plate for limiting the ammunition. The clamping plate is rotatably connected to the second support frame, and a torsion spring is fixedly connected between the clamping plate and the adjacent second support frame.

[0009] Preferably, the second support frame is provided with a placement groove for limiting the adjacent clamping plate.

[0010] Preferably, it further includes longitudinally arranged second sliders. The longitudinally arranged second sliders are respectively vertically slidably connected to the longitudinally arranged first support frame and the longitudinally arranged second support frame. The second slider is fixedly connected with a fourth magnet, and the first support frame and the second support frame are both slidably connected with the adjacent fourth magnet. The base body, the first support frame and the second support frame are all fixedly connected with a third magnet. The third magnets on the base body are distributed in pairs. The third magnet on one side of the base body is magnetically attracted to the fourth magnet on the adjacent first support frame, the third magnet on the other side of the base body is magnetically attracted to the fourth magnet on the adjacent second support frame, the third magnet on the adjacent first support frame is magnetically attracted to the fourth magnet, and the third magnet on the adjacent second support frame is magnetically attracted to the fourth magnet.

[0011] Preferably, it further includes third carriages distributed in pairs, the third carriages are slidably connected to the second support frame, a fourth carriage is slidably connected between adjacent third carriages, and a third spring is fixedly connected between the third carriage and the adjacent second support frame.

[0014] Preferably, it further includes fixing boxes distributed in pairs, the fixing boxes are used to guide one side of the lock bullet belt, the fixing boxes are fixedly connected to the first support frame, and a fifth spring is fixedly connected between the fixing boxes and the adjacent lock bullet belt.

[0015] Preferably, a control method for an unmanned aerial vehicle bomb dropping device includes the following steps:

[0016] S1: Connect this bomb dropping device to the unmanned aerial vehicle through the connection component;

[0017] S2: Place the ammunitions one by one from top to bottom on each lock bullet belt;

[0018] S3: Control the unmanned aerial vehicle to take off. After the unmanned aerial vehicle flies to the destination, determine the target position through the camera. After the control system receives the confirmation, send a signal to control the bomb dropping safety bolt to rotate by a certain degree, so that the bottommost ammunition freely falls towards the target position to complete a bomb dropping mission;

[0019] S4: Each time the bomb dropping safety bolt is controlled to rotate once, a bomb dropping mission is completed.

[0020] The beneficial effects are as follows:

[0021] Through the operation of controlling the bomb dropping safety bolt to rotate 180 degrees multiple times, the present invention can realize the task of the unmanned aerial vehicle carrying and dropping multiple ammunitions at one time, thereby increasing the strike intensity on the target area per unit time and improving the damage effect, which is particularly effective when facing multiple scattered targets or when suppressing the enemy's position in a short time.

[0022] Compared with the method of returning to the base to reload a single piece of ammunition each time a mission is performed, the present invention can reduce the number of times the UAV returns for replenishment by carrying multiple pieces of ammunition at a time, thereby saving time and flight costs and improving the combat efficiency and combat effectiveness of the UAV.

[0023] The present invention presses the clamping plate on the ammunition to ensure that each piece of ammunition can be independently and effectively fixed, so as to prevent the ammunition from being kept stable during transportation, take-off and landing, and flight, and to prevent the ammunition from being collided, rolled or shifted due to factors such as the movement of the drone and airflow changes, thereby reducing the risk of accidental explosion.

[0024] The present invention limits the ammunition by means of a clamping plate, which helps to maintain the correct posture and preset position of the ammunition on the bullet-locking belt, and is convenient for accurate positioning and bombing. The unified fixing method is also conducive to standardized management of different types of ammunition, ensuring that each type of ammunition meets the same loading standards and technical requirements before being launched, and reducing errors caused by human factors.

[0025] The present invention realizes the speed of the loading process through the magnetic positioning and fixing function, reduces manual intervention, and greatly improves the loading speed and efficiency. The operator only needs to insert the first support frame and the second support frame into the predetermined position to fix them by themselves. This rapid capability is particularly important in emergency tasks or high-tempo combat environments.

[0026] The fourth slide of the present invention will also pull the bullet-locking belt to the left during the downward sliding process, assisting the right side of the bullet-locking belt to separate from the supporting block, effectively preventing the bullet-locking belt from being stuck, avoiding affecting the smooth sliding out of subsequent ammunition, thereby avoiding affecting the delivery order and rhythm, and ensuring that each delivery of ammunition is not affected by the previous delivery.

[0027] The present invention guides the bullet-locking belt through a fixed box and limits the bullet-locking belt through a fifth spring, so that the bullet-locking belt can pop out and open quickly and smoothly under the elastic force of the reset fifth spring. The bullet-locking belt slides back and forth due to complex flight environments such as strong airflow or violent movement of the drone, causing it to remain stuck on the bullet-locking belt, thereby affecting the delivery of ammunition.

Detailed implementation manners

[0041] Reference to embodiments in this specification means that the particular features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0042] Embodiment 1: An unmanned aerial vehicle bomb dropping device, in combination with the attached Figure 1 to the attached Figure 6 , comprising a base body 1, a bomb dropping safety bolt 101 is rotatably connected to the right side of the base body 1, and the bomb dropping safety bolt 101 is rotated wirelessly controlled by a control system. A connecting component 2 is fixedly connected to the top of the base body 1, and a camera 3 is fixedly connected to the rear side of the base body 1. The camera 3 is used to determine the bomb dropping target position. Two first support frames 4 arranged longitudinally are fixedly connected to the right side of the base body 1, and adjacent first support frames 4 are engaged with each other. Two second support frames 401 arranged longitudinally are fixedly connected to the left side of the base body 1, and adjacent second support frames 401 are engaged with each other. A locking belt 5 is rotatably connected to the upper part of the second support frame 401. A first sliding frame 6 is slidably connected to the first support frame 4 in the up and down direction, and adjacent first sliding frames 6 are engaged with each other. The topmost first sliding frame 6 is in pressing fit with the bomb dropping safety bolt 101. First sliders 7 are slidably connected to the front and rear sides of the first support frame 4 in the front and rear direction. The first sliders 7 are slidably connected to a supporting block 8 in the up and down direction. A first spring 9 is fixedly connected between the first slider 7 and the supporting block 8. A pair of L-shaped sliding plates 10 are slidably connected to the first sliding frame 6 in the up and down direction. The supporting block 8 is slidably connected to the adjacent L-shaped sliding plate 10. A first magnet 11 is fixedly connected to the top end of the L-shaped sliding plate 10. Second sliding frames 12 are slidably connected to the front and rear sides of the first sliding frame 6 in the up and down direction. The second sliding frame 12 is in pressing fit with the adjacent first slider 7. The top of the second sliding frame 12 and the adjacent first sliding frame 6 form an elliptical groove 121 in combination. A second spring 13 is fixedly connected between the second sliding frame 12 and the adjacent first sliding frame 6. A second magnet 14 is fixedly connected to the bottom end of the second sliding frame 12, and the second magnet 14 is magnetically attracted to the adjacent first magnet 11 on the same side.

[0043] When using this drone to drop bombs, first, connect this bomb dropping device to the drone through the connecting component 2. Initially, the front and rear ends of the right side of the bomb locking belt 5 are respectively fixed and supported on the front and rear supporting blocks 8. Before the drone takes off, place the ammunitions one by one from top to bottom on each bomb locking belt 5. Under the action of the gravity of the ammunitions, the first spring 9 is compressed. Then, control the drone to take off. After the drone flies to the destination, determine the target position through the camera 3. After the control system confirms, send a signal to control the bomb dropping safety bolt 101 to rotate 180 degrees, so that the topmost first slide 6 slides upward. The topmost first slide 6 drives the remaining first slides 6 and the first sliders 7, supporting blocks 8, first springs 9, L-shaped slide plates 10, first magnets 11, second slides 12, second springs 13 and second magnets 14 on each first slide 6 to move upward synchronously;

[0044] In the above process, since initially, the second magnet 14 at the bottom end of the second slide 12 in the bottommost first slide 6 is not adsorbed by the first magnet 11, the second spring 13 wound around the second slide 12 in the bottommost first slide 6 is in a natural state, and the top of the second slide 12 in the bottommost first slide 6 is closed with the bottommost first slide 6 to form an elliptical groove 121;

[0045] For the second slides 12 at the bottom ends of the first slides 6 other than the bottommost first slide 6, the second magnets 14 are initially adsorbed by the first magnets 11. Therefore, the second springs 13 wound around the second slides 12 in the corresponding first slides 6 are in a compressed state, and the magnetic attraction force causes the corresponding second slides 12 to slide downward, so that they are not closed with the corresponding first slides 6 to form an elliptical groove 121;

[0046] In this way, when the bomb dropping safety bolt 101 rotates 180 degrees, only the second slide 12 in the bottommost first slide 6 will squeeze the adjacent first slider 7 to slide horizontally outward when moving upward with the first slide 6, thereby driving the adjacent supporting block 8 to slide horizontally outward along the adjacent L-shaped slide plate 10, so that the bottommost supporting block 8 no longer supports the bottommost bomb locking belt 5, and the bottommost ammunition free-falls towards the target position, completing a bomb dropping mission;

[0047] The ammunition no longer presses heavily on the bottommost supporting block 8, causing the bottommost first spring 9 to reset. The bottommost supporting block 8 pushes the L-shaped slide plate 10 in the bottommost first slide 6 to slide upward, thereby pushing the second magnet 14 in the second first slide 6 from the bottom up to move upward through the first magnet 11 on it, and then driving the second slide 12 in the second first slide 6 from the bottom up to slide upward along the first slide 6, so that the second slide 12 in the second first slide 6 from the bottom up moves upward to be closed with the corresponding first slide 6 to form an elliptical groove 121;

[0048] Thus, when the bomb safety bolt 101 rotates another 180 degrees, only the second carriage 12 in the second first carriage 6 from the bottom up will squeeze the adjacent first slider 7 to slide horizontally outwards when moving upwards with the first carriage 6, thereby driving the adjacent supporting block 8 to slide horizontally outwards along the adjacent L-shaped slide plate 10, so that the second supporting block 8 from the bottom up no longer supports the second ammunition locking belt 5 from the bottom up, and the second ammunition from the bottom up free-falls towards the target position, completing the bombing mission once again;

[0049] Repeating the operation of controlling the bomb safety bolt 101 to rotate 180 degrees multiple times can achieve the task of the unmanned aerial vehicle carrying and dropping multiple ammunitions at one time, thereby increasing the strike intensity on the target area per unit time, improving the damage effect, especially being very effective when facing multiple scattered targets or needing to suppress the enemy's position in a short time;

[0050] Compared with having to return to the base separately to reload a single ammunition every time a mission is executed, carrying multiple ammunitions at one time can reduce the number of times the unmanned aerial vehicle returns for resupply, thereby saving time and flight costs, and improving the combat efficiency and combat effectiveness of the unmanned aerial vehicle.

[0051] In addition, the unmanned aerial vehicle can select to drop different quantities or types of ammunitions according to the real-time battlefield situation in the air to adapt to diverse target strike requirements, such as simultaneously destroying light armored vehicles, bunkers or personnel targets.

[0052] Even if some ammunitions fail to hit or detonate successfully, the remaining ammunitions may still achieve the expected strike effect, can adapt to various tactical scenarios, and ensure a higher reaction speed and mission success rate on the battlefield.

[0053] Embodiment 2: On the basis of Embodiment 1, in combination with the attached Figure 7 , it further includes a clamping plate 15 for limiting the top of the ammunition. The clamping plate 15 is rotatably connected to the second support frame 401. A torsion spring 16 is fixedly connected between the clamping plate 15 and the adjacent second support frame 401. The second support frame 401 is provided with a placement groove 17 for limiting the adjacent clamping plate 15.

[0054] Before placing the ammunition, first rotate the clamping plate 15 upwards to open it, and the torsion spring 16 deforms. After placing the ammunition on the ammunition locking belt 5, release the clamping plate 15, and the clamping plate 15 presses on the ammunition. In this way, it is ensured that each ammunition can be independently and effectively fixed, preventing the ammunition from being unstable during transportation, takeoff and landing, and flight, and preventing the ammunition from colliding, rolling or shifting due to factors such as the actions of the unmanned aerial vehicle and changes in air flow, thereby reducing the risk of accidental explosion. After the ammunition drops, the torsion spring 16 resets, causing the clamping plate 15 to rotate downwards and be limited in the placement groove 17.

[0055] Moreover, the ammunition is limited by the pallet 15, which helps to maintain the correct posture and preset position of the ammunition on the ammunition locking belt 5, facilitating accurate positioning and bomb dropping. The unified fixing method is also conducive to the standardized management of different types of ammunition, ensuring that each type of ammunition meets the same loading standards and technical requirements before projection, and reducing errors caused by human factors.

[0056] Combined with the attached Figure 8 , it also includes second sliders 19 arranged longitudinally. The longitudinally arranged second sliders 19 are respectively slidably connected in the up and down direction to the upper parts of the longitudinally arranged first support frames 4 and the longitudinally arranged second support frames 401. The second sliders 19 are fixedly connected with fourth magnets 20. Both the first support frames 4 and the second support frames 401 are slidably connected with the adjacent fourth magnets 20. The base body 1, the first support frames 4 and the second support frames 401 are all fixedly connected with third magnets 18. The third magnets 18 on the base body 1 are distributed in pairs. The third magnets 18 on the right side of the base body 1 are magnetically coupled with the fourth magnets 20 of the adjacent first support frames 4, and the third magnets 18 on the left side of the base body 1 are magnetically coupled with the fourth magnets 20 of the adjacent second support frames 401. The third magnets 18 on the adjacent first support frames 4 are magnetically coupled with the fourth magnets 20, and the third magnets 18 on the adjacent second support frames 401 are magnetically coupled with the fourth magnets 20.

[0057] When loading ammunition, each group of first support frames 4 and second support frames 401 need to be horizontally slid and clamped onto the previous group of first support frames 4 and second support frames 401 respectively. However, the first support frames 4 or the second support frames 401 may slide horizontally randomly, and the positioning may not be accurate during clamping. To solve the above problems, the specific operations are as follows:

[0058] During the process of horizontally sliding and clamping the first support frames 4 and the second support frames 401 from front to back onto the previous group of first support frames 4 and second support frames 401, when the fourth magnets 20 correspond to the upper third magnets 18, the fourth magnets 20 slide upward and magnetically attract the upper third magnets 18, and the fourth magnets 20 drive the second sliders 19 to slide upward;

[0059] When it is necessary to disassemble an extra group of first support frames 4 and second support frames 401, manually pull the second sliders 19 downward, thereby driving the fourth magnets 20 to slide downward and disengage from the upper third magnets 18, and then the first support frames 4 and the second support frames 401 to be disassembled can be pulled out horizontally forward.

[0060] The above magnetic attraction positioning and fixing function realizes the rapidization of the loading process, reduces manual intervention, and greatly improves the loading speed and efficiency. The operator only needs to insert the first support frames 4 and the second support frames 401 into the predetermined positions, and they can be fixed by themselves. Especially in emergency tasks or high-paced combat environments, this rapid ability is crucial;

[0061] Moreover, the automatic locking can effectively prevent the ammunition from being loosely fixed due to poor snap connection or improper snap connection, reduce the risk of the ammunition falling off or internal mechanical failure during flight, and enhance the safety of the entire bomb dropping process.

[0062] Combined with the attached Figure 9 , it also includes third sliding frames 21 distributed in pairs before and after. The paired third sliding frames 21 are slidably connected to the front and rear sides of the second support frame 401. A fourth sliding frame 22 is slidably connected between adjacent third sliding frames 21. A third spring 23 is fixedly connected between the third sliding frame 21 and the adjacent second support frame 401. The second support frame 401 is fixedly connected with paired fixing frames 24, and the fourth sliding frame 22 moves downward to contact the adjacent fixing frame 24.

[0063] During continuous delivery, an unobstructed delivery channel is crucial for maintaining the delivery rate and coherence, so that the UAV can quickly and accurately execute tasks of intensive strikes or continuous coverage of the target area. Therefore, in order to ensure that the ammunition locking belt 5 can be smoothly unlocked without being stuck, when unlocking the right side of the ammunition locking belt 5, it is necessary to pull the ammunition locking belt 5 to the left with the help of the fourth sliding frame 22. The specific operation is as follows:

[0064] When the right side of the ammunition locking belt 5 is fixedly supported on the supporting block 8, the fourth sliding frame 22 is pushed upward by the tightened ammunition locking belt 5, and the third spring 23 is compressed. The fourth sliding frame 22 drives the third sliding frame 21 to slide upward. When the supporting block 8 slides outwards and no longer supports the ammunition locking belt 5, the ammunition locking belt 5 becomes loose. At this time, the third spring 23 resets and drives the third sliding frame 21 to slide downward, thereby driving the fourth sliding frame 22 to slide downward. Under the guiding action of the fixing frame 24, the fourth sliding frame 22 will also pull the ammunition locking belt 5 to the left during the downward sliding process, assisting the right side of the ammunition locking belt 5 to disengage from the supporting block 8, effectively preventing the ammunition locking belt 5 from being stuck, avoiding affecting the smooth sliding out of the subsequent ammunition, and thus avoiding affecting the delivery sequence and rhythm, ensuring that each ammunition delivery is not affected by the previous delivery.

[0065] Combined with the attached Figure 10 , it also includes paired blocking frames 25. The blocking frames 25 are vertically slidably connected to the second support frame 401. The third sliding frame 21 moves to contact the adjacent blocking frame 25. The blocking frame 25 is in extrusion fit with the adjacent clamping plate 15. The second support frame 401 is fixedly connected with paired fixing blocks 26. The fixing blocks 26 are slidably connected to the adjacent blocking frame 25. A fourth spring 27 is fixedly connected between the fixing block 26 and the adjacent blocking frame 25.

[0066] When the clamping plate 15 rotates downward, it will clamp the ammunition and affect the dropping of the ammunition. Therefore, it is necessary to delay the opening of the clamping plate 15 when the ammunition drops. The specific operation is as follows:

[0067] When the pallet 15 rotates upward, it will squeeze the stop bracket 25 to slide downward, and the fourth spring 27 is compressed. When the pallet 15 passes over the stop bracket 25, the fourth spring 27 resets and drives the stop bracket 25 to slide upward, thereby shifting the pallet 15. When the third carriage 21 slides downward and contacts the stop bracket 25, the ammunition has already fallen. Then the stop bracket 25 is pushed downward by the third carriage 21 again, and the fourth spring 27 is compressed again, releasing the limit of the stop bracket 25 on the pallet 15.

[0068] In summary, the delayed opening of the pallet 15 helps to achieve a more stable and gradual separation process between the ammunition and the drone, reducing the impact force of the rapid opening of the pallet 15 on the ammunition, preventing the ammunition from colliding or damaging the structure of the drone, enhancing the safety of the overall system, and also preventing the track that affects the descent of the ammunition from affecting its accuracy.

[0069] Combined with the attached Figure 11 to the attached Figure 12 It also includes fixed boxes 28 distributed in pairs front and back. The fixed boxes 28 are used to guide the right side of the ammunition locking belt 5. The paired fixed boxes 28 are respectively fixed on the front and back sides of the first support frame 4, and a fifth spring 29 is fixed between the fixed box 28 and the adjacent ammunition locking belt 5.

[0070] When the ammunition locking belt 5 is limited on the supporting block 8, the fifth spring 29 is compressed. During the process that the supporting block 8 slides outwards and no longer limits the right side of the ammunition locking belt 5, the ammunition locking belt 5 may also slide back and forth due to complex flight environments such as strong airflow or violent movement of the drone, resulting in still being stuck on the ammunition locking belt 5, thus affecting the delivery of the ammunition. To avoid this situation, it is necessary to guide the ammunition locking belt 5 through the fixed box 28 and limit the ammunition locking belt 5 through the fifth spring 29 at the same time, so that the ammunition locking belt 5 can quickly and smoothly pop open under the elastic force of the reset fifth spring 29.

[0071] Embodiment 3: On the basis of Embodiment 2, a control method for a drone bomb dropping device includes the following steps:

[0072] S1: Connect this bomb dropping device to the drone through the connection component 2;

[0073] S2: Place the ammunition one by one from top to bottom on each ammunition locking belt 5;

[0074] S3: Control the drone to take off. After the drone flies to the destination, determine the target position through the camera 3. After the control system is confirmed, send a signal to control the bomb dropping safety bolt 101 to rotate, so that the bottommost ammunition free-falls towards the target position, completing one bomb dropping mission;

[0075] S4: Each time the bomb dropping safety bolt 101 is controlled to rotate, one bomb dropping mission is completed.

[0076] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
