Description

Technical Field

[0001] This invention relates to a medical supply airdrop box for field emergency rescue, belonging to the technical field of medical airdrop boxes. Background Technology

[0002] In scenarios such as wilderness exploration, disaster relief (e.g., earthquakes, floods, landslides), and medical support in remote areas, due to factors such as complex geographical environment, traffic disruptions, or difficulty in rapid personnel arrival, it is often necessary to urgently transport medical supplies to the incident site by airdrop in order to meet the emergency needs of the injured and ensure the basic medical supply of the affected people. Airdrop has become an efficient and fast means of material delivery in such scenarios.

[0003] However, existing medical airdrop boxes still have key technical defects in actual use, making it difficult to fully meet the core needs of wilderness emergency rescue. The main problems are concentrated in the following aspects:

[0004] Locating the airdrop crate after it lands is difficult: Wild environments are mostly complex terrains such as forests, mountains, and wastelands. The airdrop crate itself lacks active target identification functions and is easily obscured by vegetation and confused with the colors of the natural environment after landing. Rescuers or those being rescued need to spend a lot of time searching, which seriously delays the time to retrieve medical supplies. Especially during the golden window for emergency treatment, this problem may directly affect the treatment effect of injured people. Therefore, it needs to be improved. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-9This invention provides a technical solution: a field first aid medical supply airdrop box, comprising a medical airdrop box body 1, with support feet 4 on both sides of the medical airdrop box body 1, and the support feet 4 being connected to the side walls of the medical airdrop box body 1 via buffer components; a smoke box 7 is fixedly installed on the top of the medical airdrop box body 1, and a smoke exhaust port 8 is installed on the top of the smoke box 7; a smoke release component is provided inside the smoke box 7; a first insertion hole 36 is opened on the outer wall of the smoke box 7, and a transmission plate 6 is slidably inserted into the first insertion hole 36. The end of the 6 furthest from the smoke box 7 is connected to the top of the support foot 4 via a trigger opening component. A rectangular tube 10 is vertically installed at the bottom of the transmission plate 6, and a limiting component is provided inside the rectangular tube 10. A tension spring 38 is horizontally installed between the rectangular tube 10 and the smoke box 7. A ribbon storage box 9 is installed on the top of the medical airdrop box body 1, and a ribbon flying outlet 19 is opened on the top of the ribbon storage box 9. A second insertion hole 37 is opened on the outer wall of the ribbon storage box 9, and a gate 18 is slidably inserted into the second insertion hole 37. A conspicuous component is provided inside the ribbon storage box 9.

[0029] The trigger opening component includes a drive plate 5, a trapezoidal block 11, a rectangular area 12, and a cylinder 13. The rectangular area 12 is opened through the end of the drive plate 6 away from the smoke box 7. The drive plate 5 is vertically slidably mounted on the top of the medical airdrop box body 1, and the trapezoidal block 11 is mounted on the outer wall of the drive plate 5 away from the medical airdrop box body 1. The top of the trapezoidal block 11 is located in the rectangular area 12. The cylinder 13 is rotatably mounted on the side of the rectangular area 12 away from the smoke box 7. The cylinder 13 and the trapezoidal block 11 cooperate with each other to pull the drive plate 6 out from the first insertion hole 36.

[0030] In an embodiment of the present invention, the medical airdrop box body 1 serves as the core load-bearing structure. The support feet 4 on both sides are elastically connected to the body 1 through buffer components. The smoke box 7 and the ribbon storage box 9 at the top form a dual-visible positioning combination. The trigger opening component, which includes a drive plate 5, a trapezoidal block 11, a rectangular area 12, a cylinder 13, and a limiting component, and includes a first spring 28, a lifting plate 29, a roller 30, a lifting handle 31, a guide hole 32, and a limiting groove 33, constitutes a linkage mechanism that starts upon landing. During the airdrop, the medical airdrop box body 1 carries various emergency supplies. The buffer component first contacts the ground through the support feet 4 and absorbs the impact force to prevent damage to the supplies inside the box. At the same time, the trigger opening component is driven by the displacement of the support feet 4, which drives the transmission plate 6 to be pulled out from the first insertion hole 36 of the smoke box 7, releasing the blockage of the smoke release component. The limiting component inside the rectangular cylinder 10 locks its position after the transmission plate 6 is in place to prevent the visibility function from being interrupted. Finally, the smoke release component releases smoke, and the visibility component pops out ribbons, forming a dual-positioning mark.

[0031] By coordinating multiple components, the system achieves integrated operation of airdrop landing, buffer protection, and conspicuous positioning. This not only solves the problem of difficult positioning of traditional airdrop boxes after landing, but also protects the integrity of the supplies inside the box through the buffer components, greatly improving the reliability and practicality of supplies delivery in field emergency rescue scenarios.

[0032] Please see Figure 9 Furthermore, the buffer assembly includes a cylindrical tube 2, a support leg 3, and a second spring 34. The cylindrical tube 2 is vertically and symmetrically installed on both sides of the medical airdrop box body 1, and the support leg 3 is vertically slidably inserted into the cylindrical tube 2. The bottom of the support leg 3 is installed on the top of the support foot 4, and the second spring 34 is vertically installed on the top of the support leg 3. The top of the second spring 34 is fixedly installed on the inner top of the cylindrical tube 2.

[0033] In an embodiment of the present invention, the transmission process of the buffer assembly revolves around the conversion of the impact force when the airdrop box falls from a height to the ground. The support leg 4 first contacts the ground and bears the vertically downward impact force, which drives the support leg 3 to slide upward along the inner wall of the cylindrical cylinder 2. During the upward movement of the support leg 3, the second spring 34 connected to its top is compressed, and the spring force acts in the opposite direction on the support leg 3, converting part of the impact force into the elastic potential energy of the spring. At the same time, when the support leg 3 slides inside the cylindrical cylinder 2, the inner wall of the cylindrical cylinder 2 forms a guiding constraint on the support leg 3, preventing the support leg 3 from deviating and causing buffer failure.

[0034] Compared to traditional single foam cushioning structures, this cushioning component, through a combination of spring elastic cushioning and cylindrical guidance, can effectively absorb the impact force when airdropped, preventing damage to fragile materials such as glass-bottled medicines and precision medical instruments; at the same time, the sliding cooperation between the support leg 3 and the cylindrical tube 2 ensures stability and no shifting during the cushioning process, further enhancing the protection of the materials inside the box.

[0035] Please see Figure 9 Furthermore, each of the support legs 3 is fixedly fitted with a rubber damping ring 35, and the rubber damping ring 35 is slidably installed inside the cylindrical tube 2.

[0036] In the embodiments of the present invention, the transmission process of the rubber damping ring 35 and the spring buffer of the buffer assembly form a damping and elastic synergy. When the support leg 3 slides upward inside the cylindrical cylinder 2, the rubber damping ring 35 fixedly sleeved on the outer wall of the support leg 3 slides synchronously along the inner wall of the cylindrical cylinder 2, and a sliding friction force is generated between the rubber damping ring 35 and the inner wall of the cylindrical cylinder 2. This friction force works together with the elastic force of the second spring 34 to slow down the upward movement speed of the support leg 3 and prevent the spring from rebounding and oscillating due to excessive deformation. When the support leg 3 is reset downward by the spring force, the rubber damping ring 35 generates a reverse friction force again to suppress the rapid descent of the support leg 3 and ensure that the airdrop box is stably parked after landing.

[0037] The damping effect of the rubber damping ring 35 eliminates the oscillation and rebound problem that is prone to occur in traditional spring buffers, allowing the airdrop box to quickly stabilize after landing and avoiding damage to the contents of the box due to continuous shaking. At the same time, the rubber material has wear-resistant and anti-aging properties, which can ensure the long service life of the buffer components and adapt to the needs of repeated use in complex outdoor environments.

[0038] Please see Figure 8 Furthermore, the limiting components include a first spring 28, a lifting plate 29, and a limiting groove 33. The top of the medical airdrop box body 1 is located directly below the transmission plate 6 and a limiting groove 33 is provided. The bottom of the rectangular tube 10 is slidably inserted with the lifting plate 29, and the top of the lifting plate 29 is vertically symmetrically mounted with the first spring 28. The top of the first spring 28 is fixedly mounted on the inner top of the rectangular tube 10. The bottom of the lifting plate 29 is rotatably mounted with a roller 30, and the roller 30 rotates on the top of the medical airdrop box body 1. The outer wall of the rectangular tube 10 is provided with a guide hole 32, and a lifting handle 31 is inserted into the guide hole 32. The insertion end of the lifting handle 31 is fixedly mounted on the outer wall of the lifting plate 29 and is used to drive the lifting plate 29 to move upward within the rectangular tube 10.

[0039] In the embodiments of the present invention, the transmission process of the limiting component is divided into two stages: locking and unlocking. In the locking stage, when the transmission plate 6 slides away from the smoke box 7 under the drive of the trigger opening component, the rectangular cylinder 10 moves synchronously with the transmission plate 6, and the roller 30 at the bottom of the lifting plate 29 slides along the top of the medical airdrop box body 1. When the transmission plate 6 slides to the preset position, the roller 30 moves exactly above the limiting groove 33. At this time, the first spring 28 stretches elastically due to the loss of the support force at the top of the body 1, pushing the lifting plate 29 to slide downward, so that the roller 30 is embedded in the limiting groove 33, thereby locking the position of the transmission plate 6. In the unlocking stage, when the rescuers find the airdrop box, they only need to pull the lifting handle 31 upward. The lifting handle 31 slides along the guide hole 32 and drives the lifting plate 29 to move upward. The roller 30 disengages from the limiting groove 33, which can push the transmission plate 6 to reset.

[0040] The locking function ensures that the visible components and smoke release components continue to work, preventing positioning interruption due to accidental slippage of the transmission plate 6; the unlocking process only requires pulling the lifting handle 31, which is simple and convenient to operate and meets the needs of quickly retrieving supplies in field emergency rescue scenarios; at the same time, the rotation design of the roller 30 reduces the friction when the lifting plate 29 moves, ensuring a smooth and stable locking and unlocking process.

[0041] Please see Figure 4 and Figure 6Furthermore, the smoke release assembly includes a drive rod 14, a laser lamp 23, and a second fan blade 40. A first gear compartment 15 is fixedly installed at the bottom of the smoke box 7. An installation plate 22 is horizontally installed inside the smoke outlet 8, and a drive rod 14 is vertically rotatably installed at the bottom of the installation plate 22. A second fan blade 40 is installed on the drive rod 14 inside the smoke outlet 8. Laser lamps 23 are symmetrically installed on the top of the installation plate 22. A first bevel gear 24 is installed at the bottom of the drive rod 14, which rotatably passes through the top of the first gear compartment 15. A second bevel gear 25 meshes with the first bevel gear 24. Smoke oil is added to the smoke box 7, and smoke is generated by heating the smoke through a heating rod inside the smoke box 7.

[0042] In an embodiment of the present invention, the transmission process of the smoke release component is achieved through power linkage and smoke extraction. When the transmission plate 6 is pulled out from the first insertion hole 36, the heating rod in the smoke box 7 is powered on and starts to heat the smoke oil stored in the box. The smoke oil vaporizes after being heated to form high-concentration smoke. At the same time, the motor 39 starts and drives the transmission rod 16 to rotate. The end of the transmission rod 16 that passes through the smoke box 7 drives the second bevel gear 25 to rotate. The second bevel gear 25 meshes with the first bevel gear 24 to drive the drive rod 14 to rotate synchronously. The second fan blade 40 at the top of the drive rod 14 rotates with the drive rod 14 to generate an upward airflow, which quickly extracts the smoke in the smoke box 7 from the exhaust port 8. In addition, the laser light 23 at the top of the mounting plate 22 lights up synchronously. The laser beam penetrates the smoke to form a bright smoke column, which enhances the positioning effect.

[0043] By combining heating and vaporization with a fan-guided smoke system, the smoke release speed is increased. The laser light 23, in conjunction with the smoke, makes the positioning marker effective in daylight, nighttime, and low-visibility environments, solving the problem of traditional airdrop box positioning being limited by ambient light.

[0044] Please see Figure 4 Furthermore, the display component includes a second gear compartment 20 and a first fan blade 21. The second gear compartment 20 is fixedly installed at the bottom of the ribbon storage box 9, and the first fan blade 21 is provided at the top of the second gear compartment 20. A rotating rod is vertically installed at the bottom of the first fan blade 21, and the bottom of the rotating rod rotates through the top of the second gear compartment 20 to install a third bevel gear 26. Multiple ribbons are installed inside the ribbon storage box 9 directly above the first fan blade 21, and the ribbons are blown out of the ribbon storage box 9 through the first fan blade 21.

[0045] In an embodiment of the present invention, the transmission process of the visible component and the smoke release component share power and complement each other in effect. After the motor 39 is started, its output shaft drives the transmission rod 16 to rotate. The transmission rod 16 passes through one end of the ribbon storage box 9 and drives the fourth bevel gear 27 to rotate. The fourth bevel gear 27 meshes with the third bevel gear 26 to drive the rotating rod at the bottom of the first fan blade 21 to rotate. The rotating rod drives the first fan blade 21 to rotate at high speed, forming an upward airflow in the ribbon storage box 9. At the same time, when the trigger opening component drives the transmission plate 6 to slide, the transmission plate 6 pulls the gate 18 through the pull rod 17 to be pulled out from the second insertion hole 37, releasing the blockage of the ribbon flying outlet 19. The airflow generated by the first fan blade 21 blows the colorful ribbons in the ribbon storage box 9 out of the ribbon flying outlet 19, and the ribbons fly on the top of the airdrop box to form a dynamic mark.

[0046] The visible component and the smoke release component share the same motor 39, which simplifies the overall structural design and reduces energy consumption. The dynamic markings formed by the colored ribbons complement the static markings of the smoke, enabling both long-distance positioning through the smoke and close-range identification through the colored ribbons. When rescuers approach, they can quickly lock the precise location of the airdrop box 1, further improving positioning efficiency.

[0047] Please see Figure 6 Furthermore, a motor 39 is fixedly installed on the outer wall of the ribbon storage box 9. A transmission rod 16 is installed horizontally between the smoke box 7 and the ribbon storage box 9. One end of the transmission rod 16 passes through the ribbon storage box 9 and rotates through the second gear compartment 20 to install a fourth bevel gear 27. A third bevel gear 26 meshes with the fourth bevel gear 27. One end of the transmission rod 16 passes through the smoke box 7 and rotates through the first gear compartment 15 to install a second bevel gear 25. A first bevel gear 24 meshes with the second bevel gear 25.

[0048] In an embodiment of the present invention, the linkage transmission process between the motor 39 and the transmission rod 16 is a single power source with dual outputs. The motor 39 is fixedly installed on the outer wall of the ribbon storage box 9, and its output shaft is directly connected to one end of the transmission rod 16 through a coupling. When the motor 39 is powered on and started, the output shaft drives the transmission rod 16 to rotate at a constant speed around its axis. The two ends of the transmission rod 16 extend into the smoke box 7 and the ribbon storage box 9, respectively. One end of the transmission rod 16, which penetrates the smoke box 7, meshes with the first bevel gear 24 through the second bevel gear 25, and transmits power to the drive rod 14 to drive the second fan blade 40. The other end of the transmission rod 16, which penetrates the ribbon storage box 9, meshes with the third bevel gear 26 through the fourth bevel gear 27, and transmits power to the rotating rod to drive the first fan blade 21. During the entire transmission process, the transmission rod 16 is supported by the sealed bearing at the connection between the smoke box 7 and the ribbon storage box 9, ensuring stable rotation and preventing smoke leakage.

[0049] Please see Figure 1 and Figure 6Furthermore, a pull rod 17 is horizontally installed on the side of the gate 18 near the smoke box 7, and the end of the pull rod 17 slides through the smoke box 7 and connects to the outer wall of the transmission plate 6 inserted in the first insertion hole 36.

[0050] In an embodiment of the present invention, the transmission process of the gate 18 and the lever 17 is a passive linkage trigger. In the initial state, the gate 18 is inserted into the second insertion hole 37 of the ribbon storage box 9, completely blocking the ribbon flying outlet 19 to prevent the ribbon from accidentally coming out due to vibration during the airdrop process. The side of the gate 18 closest to the smoke box 7 is fixedly connected to the outer wall of the transmission plate 6 through the lever 17. The part of the lever 17 that penetrates the smoke box 7 leaves a sliding gap between it and the box wall to ensure no jamming. When the trigger opening component drives the transmission plate 6 to slide away from the smoke box 7, the transmission plate 6 applies a horizontal pulling force to the gate 18 through the lever 17, causing the gate 18 to slide along the inner wall of the second insertion hole 37 toward the smoke box 7. As the transmission plate 6 continues to slide, the gate 18 is gradually pulled out of the ribbon storage box 9. When the transmission plate 6 slides to the preset position, the gate 18 is completely disengaged from the second insertion hole 37, and the ribbon flying outlet 19 is fully opened, providing a channel for the ribbon to fly out.

[0051] The gate 18 is linked to the transmission plate 6 by the lever 17, eliminating the need for additional power to open the gate 18 and simplifying the control logic. The gate 18 opens as it slides with the transmission plate 6, ensuring that the ribbon launch outlet 19 opens simultaneously with the smoke release component, achieving synchronous visibility of the smoke and ribbon and avoiding a reduction in positioning effectiveness due to asynchronous visibility. In addition, the initial sealing of the ribbon launch outlet 19 by the gate 18 effectively prevents the ribbon from getting damp, damaged, or lost during the airdrop process, ensuring the effectiveness of the visibility function.

[0052] The workflow of this embodiment is as follows:

[0053] 1. When the medical airdrop container 1 is airdropped from a high altitude and lands, regardless of its parabolic trajectory, the two side support legs 4 will be the first to contact the ground and absorb the impact. This impact force drives the support leg 3 at the top of the support leg 4 to slide along the inner wall of the cylindrical cylinder 2 (triggered without vertical compression). As the support leg 3 slides, it compresses the second spring 34 at the top of the cylindrical cylinder 2, while the rubber damping ring 35 on its outer wall generates sliding friction with the inner wall of the cylindrical cylinder 2. Through the combined effect of the elastic buffering of the second spring 34 and the damping and shock absorption of the rubber damping ring 35, the impact force from different directions can be quickly absorbed, suppressing the rebound and vibration of the container and preventing damage to the internal emergency supplies due to impact or shaking.

[0054] 2. During this process, the support foot 4 moves upward, simultaneously driving the drive plate 5 to slide vertically upward along the top of the medical airdrop box body 1. The trapezoidal block 11 installed on the outer wall of the drive plate 5 moves upward accordingly. Since the top of the trapezoidal block 11 is located in the rectangular area 12 of the transmission plate 6, and a cylinder 13 is rotatably installed on the side of the rectangular area 12 away from the smoke box 7, the trapezoidal block 11 forms an inclined surface cooperation with the cylinder 13 when it moves upward, converting the vertical displacement into a horizontal thrust, pushing the transmission plate 6 to slide away from the smoke box 7, so that the transmission plate 6 is gradually pulled out from the first insertion hole 36 on the outer wall of the smoke box 7; at the same time, the transmission plate 6 drives the gate 18 to slide along the second insertion hole 37 on the outer wall of the ribbon storage box 9 towards the smoke box 7 through the pull rod 17, so that the gate 18 is completely disengaged from the second insertion hole 37, releasing the blockage of the ribbon flying outlet 19 at the top of the ribbon storage box 9.

[0055] 3. During the sliding process of the transmission plate 6, the vertically installed rectangular tube 10 at its bottom moves synchronously. The roller 30 at the bottom of the lifting plate 29 inside the rectangular tube 10 slides along the top of the medical airdrop box body 1. When the transmission plate 6 slides to the preset position, the roller 30 is exactly aligned with the limiting groove 33 at the top of the medical airdrop box body 1. At this time, the first spring 28 at the top of the lifting plate 29 loses the top support force and stretches elastically, pushing the lifting plate 29 to slide downward, so that the roller 30 is embedded in the limiting groove 33, thereby locking the position of the transmission plate 6 and preventing it from accidentally resetting. At the same time, the tension spring 38 horizontally installed between the rectangular tube 10 and the smoke box 7 is in a stretched state, providing pre-tightening force for the subsequent manual reset of the transmission plate 6.

[0056] 4. After the transmission plate 6 is pulled out from the first insertion hole 36, the heating rod inside the smoke box 7 is powered on and activated, heating and vaporizing the smoke oil stored independently and sealed inside the box to form a high-concentration smoke. The second fan blade 40 inside the smoke outlet 8 is directly driven to rotate by the built-in micro motor, quickly expelling the smoke. The smoke oil storage area and the fan blade are isolated to avoid mutual interference. At the same time, the micro motor inside the ribbon storage box 9 is activated, pushing the ribbon through the built-in anti-tangling guide structure, and smoothly discharged from the ribbon flying outlet 19 to form a dynamic mark. The laser light 23 inside the smoke outlet 8 lights up simultaneously, and the laser beam penetrates the smoke to form a bright smoke column. Compared with the existing conventional single-marking solution of colored smoke cans, this design simplifies the transmission structure to avoid failure. Through the coordinated positioning of smoke, laser and anti-tangling ribbon, the mark is more stable and accurate, suitable for airdrop scenarios, and effectively shortens the rescue and search time.

[0057] 5. The transmission rod 16 passes through one end of the ribbon storage box 9, which drives the fourth bevel gear 27 in the second gear compartment 20 to rotate. The fourth bevel gear 27 meshes with the third bevel gear 26 on the bottom rotating rod of the first fan blade 21, causing the first fan blade 21 to rotate at high speed and form an upward airflow in the ribbon storage box 9. This airflow blows the pre-stored colored ribbons in the ribbon storage box 9 out of the opened ribbon flying outlet 19. The ribbons fly on the top of the medical airdrop box body 1 to form a dynamic mark, which forms a dual positioning with the bright smoke column, making it convenient for rescuers to quickly identify and find the medical airdrop box body 1.

[0058] 6. When the rescuers arrive, turn off the motor 39 and the heating rod. Simply pull the lifting handle 31 in the guide hole 32 on the outer wall of the rectangular tube 10 upward. The lifting handle 31 drives the lifting plate 29 to slide upward in the rectangular tube 10, so that the roller 30 is disengaged from the limiting groove 33, and the position lock of the transmission plate 6 is released. At this time, the rebound force of the tension spring 38 pulls the transmission plate 6 to reset towards the smoke box 7. The transmission plate 6 is reinserted into the first insertion hole 36 and drives the gate 18 to reset and insert into the second insertion hole 37 through the pull rod 17. The smoke exhaust channel of the smoke box 7 and the flight outlet of the ribbon storage box 9 are closed, and the medical airdrop box body 1 can be opened to retrieve the internal emergency supplies.
