Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to an emergency medical supplies delivery UAV. Background Technology

[0002] In general, acute illnesses such as cardiovascular diseases develop rapidly, with the optimal rescue time being only 4 minutes. Without timely and scientific treatment, the mortality rate is extremely high. Traditional rescue mechanisms often suffer from the following problems: ground traffic congestion frequently prevents rescue vehicles from reaching the patient's location in time, easily missing the optimal rescue opportunity and resulting in a low success rate; local personnel often lack access to professional guidance from remote medical personnel, making it difficult to provide scientific first aid, further reducing the success rate of emergency treatment. However, existing drones possess excellent maneuverability and are not constrained by terrain or space. Therefore, enabling drones to quickly load, unload, and transport emergency medications is currently one of the important research directions for assisting in emergency patient care. Summary of the Invention

[0003] The purpose of this invention is to provide an emergency medicine transport drone that can quickly load, unload, and transport emergency medicines.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an emergency medical supplies transport drone, comprising a multi-rotor drone, a camera mounted on the front end of the drone, and an automatic loading and unloading device for first aid kits mounted on the bottom of the multi-rotor drone. The loading and transport device includes a mounting plate 1 and a mounting plate 2 fixed to the bottom of the multi-rotor drone and spaced parallel to each other vertically, four connecting columns vertically connecting the mounting plate 1 and the mounting plate 2, two lifting rods 1 and 2 slidably inserted through the mounting plate 2 and having oblique quadrangular prism shapes, and two lifting rods with one end hinged to the lower end of the lifting rod. The lifting assembly consists of a first connecting rod, two connecting rods at one end that are hinged together to the lower end of the second lifting rod, and a third connecting rod at both ends that are hinged to the other ends of the first and second lifting rods respectively. The first and second lifting rods are symmetrical to each other and are located close to both sides of the second mounting plate. The second mounting plate has through holes for the first and second lifting rods to slide obliquely through. The lid of the first aid kit has two T-shaped through slots, and the top opening of the T-shaped through slots allows the first, second, connecting rods and the third lifting rod to enter.

[0005] By adopting the above technical solution, when the drone needs to carry a first aid kit, the multi-rotor drone can first be manually placed on the lid of the first aid kit containing first aid medicines. At the same time, the lifting rods 1, 2, 1, 2, and 3 at the bottom of the multi-rotor drone should be aligned and inserted into the two T-shaped slots on the lid. Then, the lifting assembly on the mounting plate 2 will drive lifting rods 1 and 2 to slide upward relative to the mounting plate 2. Since lifting rods 1 and 2 are oblique quadrangular prisms and slide obliquely through the through holes on the mounting plate 2, during the upward sliding process, lifting rods 1 and 2 will respectively drive the two connecting rods 1 and 2 at their lower ends to open the connecting rod 3, so that the connecting rod 3 extends into the T-shaped slots on both sides of the lid. Simultaneously, the bottom of mounting plate two will gradually move closer to the first aid kit lid. Finally, when mounting plate two is tightly attached to the first aid kit lid, connecting rod three will not only engage in the T-shaped slot, but also work with mounting plate two to fix the first aid kit under the multi-rotor drone, thus ensuring the drone safely and stably transports the first aid kit to the patient's location. When the drone needs to unload the first aid kit, the lifting assembly will reverse the driving of lifting rod one and lifting rod two, causing them to slide downward relative to mounting plate two. Then, connecting rod one and connecting rod two will gradually retract, driving connecting rod three to exit from the recesses on both sides of the T-shaped slot. Once connecting rod three is completely out, the connection between the first aid kit lid and mounting plate two is released, making it easier for the assistant to quickly retrieve the medication to provide first aid to the patient.

[0006] A further configuration of the present invention includes: the lifting assembly comprising a pair of parallel, spaced-apart rotating shafts 1 rotating on the mounting plate 2; two pairs of spur gears respectively fixed on the two rotating shafts 1; racks respectively fixed on one side of the lifting rod 1 and the lifting rod 2 and meshing with the spur gears; a rotating shaft 2 rotating on the mounting plate 2 and perpendicularly located between the two rotating shafts 1; a pair of bevel gears 1 fixedly mounted on the rotating shaft 2; a pair of bevel gears 2 respectively fixed on the two rotating shafts 1 and meshing with the bevel gears 1; a worm gear fixedly mounted in the middle of the rotating shaft 2; a worm rotatably mounted on the mounting plate 2 and meshing with the worm gear; and a micro motor fixedly mounted in the middle of the mounting plate 2 and connected at its output end to the worm. The mounting plate 2 has a cavity 1 inside for housing the rotating shafts 1 and 2, the bevel gears 1 and 2, the worm gear, and the worm. The mounting plate 2 has a cavity 2 on one side of the through hole for meshing transmission between the spur gears and the racks.

[0007] By adopting the above technical solution, when it is necessary to drive lifting rod one and lifting rod two to move up and down relative to mounting plate two, firstly, the micro motor drives the worm gear to mesh with the worm wheel, causing rotating shaft two to rotate. Then, rotating shaft two drives bevel gear one to mesh with bevel gear two, causing rotating shaft one to rotate. Finally, rotating shaft one drives spur gear to mesh with rack, causing lifting rod one and lifting rod two, which are connected to the rack, to slide and interlock up and down relative to the through hole of mounting plate two. The cavities one and two within mounting plate two not only ensure the stability and safety of the transmission of each component but also save external installation space.

[0008] A further configuration of the present invention is as follows: the connecting rods 1, 2, and 3 are flush with each other and have the same thickness and width; each end of the connecting rod 1 or 2 is fixedly provided with a hinge seat 1; the lower ends of the lifting rod 1 and 2 are fixedly provided with a hinge shaft 1; a hinge hole 1 is provided on the hinge seat 1 at one end of the connecting rod 1 and 2 for the hinge shaft 1 to rotate through; each end of the connecting rod 3 is fixedly provided with a hinge seat 2; a hinge shaft 2 is fixedly provided on the hinge seat 2; a hinge hole 2 is provided on the hinge seat 1 at the other end of the connecting rod 1 and 2 for the hinge shaft 2 to rotate through; and the hinge seat 1, hinge seat 2, and hinge shaft 2 do not extend beyond the upper and lower end faces of the connecting rods 1, 2, and 3.

[0009] By adopting the above technical solution, not only can the ends of connecting rod one, connecting rod two, and connecting rod three be stably hinged, but connecting rod three can also be effectively engaged in the recesses on both sides of the T-slot to ensure that the first aid kit is fixed horizontally below mounting plate two.

[0010] A further feature of the present invention is that a rubber support foot is fixedly installed at the lower end of the hinge shaft extending out of the hinge hole.

[0011] By adopting the above technical solution, not only can the stable parking and take-off of the multi-rotor UAV be ensured before and after the transport of the first aid kit, but the movement of the first aid kit to the left and right sides can also be restricted during the transport of the first aid kit, further reinforcing the connection between the first aid kit and the second mounting plate.

[0012] A further feature of the present invention is that the connecting column is hollow inside, and the mounting plate one and the mounting plate two are respectively provided with openings that communicate with the interior of the connecting column. The bottom of the multi-rotor UAV is fixedly suspended by four bolts, and each bolt passes vertically through the opening and the interior of the connecting column. Nuts are threadedly connected to the top and bottom of the mounting plate one and the mounting plate two, respectively.

[0013] By adopting the above technical solution, mounting plate one and mounting plate two can be stably fixed to the bottom of the multi-rotor drone, while also helping staff to quickly install and remove mounting plate one and mounting plate two, so as to facilitate staff to maintain and service the drone.

[0014] A further configuration of the present invention is as follows: a pair of vertically parallel baffles are fixedly arranged in the middle of the mounting plate one and the mounting plate two; the micro motor is located in the gap between the two baffles; a fence one is fixedly arranged between the two connecting columns on both sides of the baffles; a lifting plate is slidably arranged between the baffles and the connecting columns; one end of the lifting rod one or the lifting rod two is slidably connected to the bottom edge of the lifting plate; a fence two is also fixedly arranged on the bottom edge of the lifting plate; and an automatic winding assembly for straightening and winding the fence two is arranged inside the mounting plate two.

[0015] By adopting the above technical solution, when the structure is loaded with a first-aid kit, lifting rod one and lifting rod two will push the lifting plate between the connecting column and the baffle to lift the mesh screen two as they slide upward relative to the mounting plate two. At the same time, the automatic winding component will straighten the mesh screen two. After the mesh screen two fills the entire gap between the connecting column and the baffle, it will work with the mesh screen one and the baffle to form a storage space outside the first-aid kit. When the structure is unloaded from the first-aid kit, lifting rod one and lifting rod two will pull the lifting plate between the connecting column and the baffle downward as they slide downward relative to the mounting plate two. At the same time, the automatic winding component inside the mounting plate two will slowly wind up the mesh screen two, opening a certain opening between the mesh screen two and the lifting plate to allow medical personnel or rescuers to retrieve or place surplus medicines or medical equipment placed inside.

[0016] A further configuration of the present invention is as follows: a dovetail slider is fixedly provided at the top of the lifting rod one and the lifting rod two; a dovetail groove is provided at the bottom of the lifting plate for the dovetail slider to slide; dovetail sliders are fixedly provided at both ends of the lifting plate; and a dovetail groove is provided on one side of the connecting column and the baffle for the dovetail sliders to slide.

[0017] By adopting the above technical solution, the relative sliding stability between the lifting plate and lifting rod one or lifting rod two, and between the lifting plate and the connecting column and the baffle, can be effectively guaranteed.

[0018] A further configuration of the present invention is as follows: the automatic winding assembly includes a pair of rotating shafts three rotating on the mounting plate two, spring clips fixed at both ends of the rotating shafts three, and a spring clipped in the middle on the spring clips. The mounting plate two has a cavity three for rotating the rotating shafts three. The rotating shafts three are parallel to the rotating shafts two and are located beside the two ends of the rotating shafts three. The mounting plate two has arc-shaped cavities four for placing the spring at both ends of the rotating shafts three. The mounting plate two has an elongated hole below the lifting plate that communicates with the cavity three. One end of the mesh two extends into the cavity three from the elongated hole, and the other end is fixedly connected to the side of the rotating shafts three.

[0019] By adopting the above technical solution, when the lifting plate pulls the fence netting out upwards, the rotating shaft three and the spring clips at both ends of it will rotate accordingly. Then, the spring clips will twist the spring, causing the spring to continuously twist and deform, thereby accumulating elastic potential energy, which will then react to the rotation of the rotating shaft three, thus achieving the effect of straightening the fence netting. When the lifting plate pulls the fence netting downwards, the elastic potential energy accumulated by the spring will be gradually released, causing the rotating shaft three to rotate in the opposite direction, thereby achieving the effect of rewinding the fence netting.

[0020] A further provision of the present invention is that a microphone and a handset for communication are mounted on the top of the mounting plate one.

[0021] By adopting the above technical solutions, it is easier for medical staff and patients or assistants to communicate, thereby better helping patients receive emergency treatment.

[0022] The beneficial effects of this invention are:

[0023] 1. Through the lifting rod one, lifting rod two and connecting rod and other structures in the above-mentioned loading and transportation device, the first aid box can be automatically and quickly attached to the bottom of the drone to quickly transport the first aid medicine to the patient's destination. It can also be automatically and quickly unloaded so that the assistant can quickly take the medicine to provide first aid treatment to the patient.

[0024] 2. Through the rotating shaft one, rotating shaft two and gear transmission structure in the above-mentioned lifting assembly, not only can each lifting rod one and lifting rod two be synchronously driven to slide up and down relative to the mounting plate two, but also only one motor is used to achieve the driving effect. In this way, while saving space and load under the drone, the energy consumption required for the lifting assembly to work can be reduced and its endurance can be improved.

[0025] 3. Through the above-mentioned baffles, connecting columns and other structures, not only can an external storage space be formed for the surplus medicines and medical devices in the first aid kit, but also, in conjunction with the lifting of lifting rod one and lifting rod two, the storage space can be opened and closed automatically. This not only effectively ensures the stable and safe transportation of first aid medicines or medical devices, but also makes it convenient for medical personnel and assistants to quickly put in and take out the medicines and devices.

[0026] 4. Through the rotating shaft and spring structure in the automatic winding assembly, not only can the second mesh be kept flat between the connecting column and the baffle to better prevent the drugs and instruments from sliding, but the second mesh can also be quickly retracted so that medical staff or assistants can quickly put in and take out the drugs and instruments inside.

[0027] 5. By installing the microphone and earpiece on the first board, it is possible to facilitate effective communication between medical staff and patients or assistants, thereby better helping patients receive emergency treatment. Attached Figure Description

[0037] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] Example: An emergency medical supplies delivery drone, such as Figure 1-4 As shown, the device includes a multi-rotor drone 1, a camera 11 mounted on the front of the drone, and a loading and transport device 3 for automatically loading and unloading a first aid kit 2 mounted on the bottom of the multi-rotor drone 1. The loading and transport device 3 includes mounting plates 31 and 32 fixed to the bottom of the multi-rotor drone 1 and spaced parallel to each other vertically; four connecting columns 33 vertically connecting mounting plates 31 and 32; two lifting rods 34 and 35 slidably inserted through mounting plate 32 and shaped like oblique quadrangular prisms; two connecting rods 36 with one end hinged to the lower end of lifting rod 34; and two connecting rods 35 with one end hinged to the lower end of lifting rod 35. 37. A lifting assembly 4, with connecting rod 38 at one end hinged to connecting rod 36 and connecting rod 37 respectively, drives lifting rod 34 and lifting rod 35 to slide up and down through mounting plate 32. Lifting rod 34 and lifting rod 35 are symmetrical to each other and are close to both sides of mounting plate 32. Mounting plate 32 has through holes 321 for lifting rod 34 and lifting rod 35 to slide obliquely through. The cover of the first aid kit 2 has two T-shaped through slots 21. The top opening of the T-shaped through slots 21 allows lifting rod 34, lifting rod 35, connecting rod 36, connecting rod 37 and connecting rod 38 to enter.

[0039] When the drone needs to carry the first aid kit 2, the multi-rotor drone 1 can first be manually placed on the lid of the first aid kit 2 containing first aid medicines. At the same time, the lifting rods 1-34, 2-35, 1-36, 2-37, and 3-38 at the bottom of the multi-rotor drone 1 should be aligned and inserted into the two T-shaped slots 21 on the lid. Then, the lifting assembly 4 on the mounting plate 2-32 will drive the lifting rods 1-34 and 2-35 to slide upward relative to the mounting plate 2-32. Since the lifting rods 1-34 and 2-35 are oblique quadrangular prisms and slide obliquely through the through holes 321 on the mounting plate 2-32, the lifting rods 1-34 and 2-35 will respectively drive the two connecting rods 1-36 and 2-37 at their lower ends to open the connecting rod 3-38, so that the connecting rod 3-38 extends into the two recesses of the T-shaped slots 21 on the lid. As the mounting plate 2 32 gradually moves closer to the lid of the first aid kit 2, the connecting rod 3 38 will not only engage with the T-shaped slot 21, but also, in conjunction with the mounting plate 2 32, fix the first aid kit 2 under the multi-rotor drone 1, thus ensuring the drone can safely and stably transport the first aid kit 2 to the patient's location. When the drone needs to unload the first aid kit 2, the lifting assembly 4 will reverse the movement of the lifting rod 1 34 and the lifting rod 2 35, causing them to slide downward relative to the mounting plate 2 32. Then, the two connecting rods 1 36 and 2 37 will gradually retract, and the connecting rod 3 38 will exit from the recesses on both sides of the T-shaped slot 21. Once the connecting rod 3 38 is completely removed, the connection between the lid of the first aid kit 2 and the mounting plate 2 32 will be released, making it easier for the assistant to quickly retrieve the medication to treat the patient. The top of the mounting plate 31 is equipped with a microphone 311 and a handset 312 for communication, which facilitates communication between medical staff and patients or assistants, thereby better helping patients receive emergency treatment.

[0040] like Figure 2 , Figure 4As shown, the lifting assembly 4 includes a pair of parallel, spaced-apart rotating shafts 41 that rotate on the mounting plate 32; two pairs of spur gears 42 respectively fixed on the two rotating shafts 41; racks 43 respectively fixed to one side of the lifting rod 34 and the lifting rod 35 and meshing with the spur gears 42; a rotating shaft 44 rotating on the mounting plate 32 and perpendicularly located between the two rotating shafts 41; a pair of bevel gears 45 fixedly mounted on the rotating shaft 44; a pair of bevel gears 46 respectively fixed to the two rotating shafts 41 and meshing with the bevel gears 45; a worm gear 47 fixedly mounted in the middle of the rotating shaft 44; a worm 48 rotatably mounted on the mounting plate 32 and meshing with the worm gear 47; and a micro motor 49 fixedly mounted in the middle of the mounting plate 32 and connected to the worm 48 at its output end. The mounting plate 32 has an opening for mounting the rotating shafts. The cavity 322 of the rotating shaft 41, rotating shaft 44, bevel gear 45, bevel gear 46, worm gear 47, and worm 48 is provided on the side of the mounting plate 32 with a cavity 323 for the meshing transmission of spur gear 42 and rack 43. When it is necessary to drive the lifting rod 34 and lifting rod 35 to move up and down relative to the mounting plate 32, the micro motor 49 first drives the worm 48 to mesh with the worm gear 47, causing the rotating shaft 44 to rotate. Then, the rotating shaft 44 will drive the bevel gear 45 to mesh with the bevel gear 46, causing the rotating shaft 41 to rotate. Finally, the rotating shaft 41 will drive the spur gear 42 to mesh with the rack 43, so that the lifting rod 34 and lifting rod 35 connected to the rack 43 slide up and down relative to the through hole 321 of the mounting plate 32. The cavities 322 and 323 within the mounting plate 32 not only ensure the stability and safety of the transmission of each component, but also save external installation space.

[0041] like Figure 2 , Figure 5As shown, connecting rod 1 (36), connecting rod 2 (37), and connecting rod 3 (38) are flush with each other and have the same thickness and width. Hinges 1 (5) are fixedly installed at both ends of connecting rod 1 (36) or connecting rod 2 (37). Hinges 1 (51) are fixedly installed at the lower ends of lifting rod 1 (34) and lifting rod 2 (35). Hinges 1 (51) are provided on the hinges 1 (5) at one end of connecting rod 1 (36) and connecting rod 2 (37) for the hinges 1 (51) to rotate through. Hinges 2 (6) are fixedly installed at both ends of connecting rod 3 (38), and hinges 2 (61) are fixedly installed on hinges 2 (6). A hinge hole 2 is provided on the hinge seat 5 at the other end of the connecting rod 6 and the connecting rod 2 37, through which the connecting shaft 2 61 rotates. The hinge seat 5, the hinge seat 2 6, and the connecting shaft 2 61 do not extend beyond the upper and lower end faces of the connecting rod 1 36, the connecting rod 2 37, and the connecting rod 3 38. Through the connection structure between the connecting rods, not only can the ends of the connecting rod 1 36, the connecting rod 2 37, and the connecting rod 3 38 be stably hinged, but the connecting rod 3 38 can also be effectively engaged in the recesses on both sides of the T-shaped through groove 21 to ensure that the first aid box 2 is horizontally fixed below the mounting plate 2 32. Among them, the lower end of the connecting shaft 1 51 extending out of the hinge hole 1 is fixedly installed with a rubber support foot 52, which can not only ensure the stable parking and take-off of the multi-rotor UAV 1 before and after carrying the first aid box 2, but also restrict the left and right movement of the first aid box 2 during transportation, further reinforcing the connection between the first aid box 2 and the mounting plate 2 32.

[0042] like Figure 1 , Figure 2 As shown, the connecting column 33 is hollow inside, and the mounting plate 31 and the mounting plate 32 are respectively provided with openings that connect to the inside of the connecting column 33. Four bolts 12 are fixedly suspended at the bottom of the multi-rotor UAV 1, and each bolt 12 passes vertically through the opening and the inside of the connecting column 33. The bolts 12 are threaded with nuts 13 at the top and bottom of the mounting plate 31 and the mounting plate 32, respectively. Through the threaded connection structure of the bolts 12 and the nuts 13, the mounting plate 31 and the mounting plate 32 can be stably fixed to the bottom of the multi-rotor UAV 1, while also helping the staff to quickly disassemble and assemble the mounting plate 31 and the mounting plate 32, so as to facilitate the staff to maintain and service the UAV.

[0043] like Figure 2 , Figure 3As shown, a pair of vertically parallel baffles 7 are fixedly installed in the middle of mounting plate 1 31 and mounting plate 2 32. A micro motor 49 is located in the gap between the two baffles 7. A fence 1 331 is fixedly installed between the two connecting columns 33 on both sides of the baffles 7. A lifting plate 8 is slidably installed between the baffles 7 and the connecting columns 33. One end of lifting rod 1 34 or lifting rod 2 35 is slidably connected to the bottom edge of the lifting plate 8. A fence 2 81 is also fixedly installed on the bottom edge of the lifting plate 8. An automatic winding assembly 9 for straightening and winding the fence 2 81 is installed inside the mounting plate 2 32. When the first aid box 2 is loaded into this structure, the lifting rod 1 34 and lifting rod 2 35 will push the lifting plate 8 between the connecting columns 33 and the baffles 7 upward as they slide upward relative to the mounting plate 2 32. When the second fence 81 is raised, the automatic rewinding component 9 will straighten the second fence 81. Once the second fence 81 fills the entire gap between the connecting post 33 and the baffle 7, it will work with the first fence 331 and the baffle 7 to form a storage space outside the first aid box 2. When the first aid box 2 is removed from the structure, the first lifting rod 34 and the second lifting rod 35 will slide downward relative to the second mounting plate 32, pulling the lifting plate 8 between the connecting post 33 and the baffle 7 downward to lower the second fence 81. At the same time, the automatic rewinding component 9 inside the second mounting plate 32 will slowly rewind the second fence 81, opening a certain opening between the second fence 81 and the lifting plate 8, so that medical personnel or rescuers can access the surplus medicines or treatment equipment placed inside.

[0044] like Figure 3 , Figure 6 As shown, dovetail sliders 39 are fixedly installed at the top of lifting rod 34 and lifting rod 35. Dovetail grooves 82 for sliding the dovetail sliders are opened at the bottom of the lifting plate 8. Dovetail sliders 83 are fixedly installed at both ends of the lifting plate 8. Dovetail grooves 71 for sliding the dovetail sliders 83 are opened on one side of the connecting column 33 and the baffle 7. Through the sliding connection structure of the dovetail sliders and the dovetail grooves, the relative sliding stability between the lifting plate 8 and the lifting rod 34 or the lifting rod 35, and between the lifting plate 8 and the connecting column 33 and the baffle 7 can be effectively guaranteed.

[0045] like Figure 4 , Figure 7As shown, the automatic winding assembly 9 includes a pair of rotating shafts 91 rotating on the mounting plate 2 32, spring clips 92 fixed at both ends of the rotating shafts 91, and a spring 93 clamped in the middle on the spring clips 92. The mounting plate 2 32 has a cavity 324 for rotating the rotating shafts 91. The rotating shafts 91 and 44 are parallel and located beside the two ends of the rotating shafts 41. The mounting plate 2 32 has arc-shaped cavities 325 at both ends of the rotating shafts 91 for holding the spring 93. The mounting plate 2 32 has an elongated hole 326 below the lifting plate 8 that connects to the cavity 324. One end of the mesh 2 81 extends from the long... The slot 326 extends into the cavity 324, and one end is fixedly connected to the side of the rotating shaft 91. When the lifting plate 8 pulls the fence 81 upward, the rotating shaft 91 and the spring 93 clips 92 at both ends will rotate accordingly. Then the spring clips 92 will twist the spring 93, causing the spring 93 to continuously twist and deform, thereby accumulating elastic potential energy and reacting on the rotation of the rotating shaft 91, thus achieving the effect of straightening the fence 81. When the lifting plate 8 lowers the fence 81 downward, the elastic potential energy accumulated by the spring 93 will gradually be released, driving the rotating shaft 91 to rotate in the opposite direction, thereby achieving the effect of pulling back and rewinding the fence 81.
