Description

Technical Field

[0001] This invention relates to the field of unmanned transportation technology, specifically an emergency rescue drone. Background Technology

[0002] Emergency rescue drones are key equipment for responding to emergencies such as natural disasters and accidents. With their flexibility, efficiency, and ability to penetrate dangerous areas, they play a vital role in various rescue scenarios. Functionally, they can be categorized as search and detection drones (equipped with sensors to locate personnel and hazards), material transport drones (transporting first-aid supplies), firefighting and rescue drones (fetching water or delivering extinguishing agents), communication relay drones (establishing temporary communication networks), and demolition and rescue drones (equipped with tools to clear passages). Their design must balance protection, endurance, and payload capacity, possessing collaborative capabilities and adaptability to harsh environments.

[0003] Drones can be used for transporting supplies in two ways: delivery and containerized. Containerized transport involves installing a loading container on the underside of the drone. Fragile and delicate supplies are placed inside the container and transported using the drone's takeoff and landing. Compared to delivery, this method maximizes the protection of supplies. However, after the drone lands with the loading container, the four propellers extending outwards with the drone's arms cause some spatial interference during loading and unloading. This requires operators to bend over to avoid the propellers when opening the container door and then close it again after the supplies are placed inside. This is especially inconvenient with a large number of propellers. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes an emergency rescue drone. This invention controls the drive rod to be pressed after landing, causing the drive plate to move upward in the drive groove. This allows the driven plate to move the bearing plate out of the loading box under hydraulic pressure, thereby bringing the loading and unloading position of materials closer to the lower edge of the drone body, thus improving the convenience of loading and unloading materials.

[0009] Preferably, the lower surface of the support plate has multiple support grooves; the lower surface of the support block is rotatably connected to ball bearings.

[0010] Preferably, a rectangular groove is provided on the upper surface of the bearing plate near the edge; a rectangular frame strip is slidably connected to the groove; a movable hole is provided through the bottom of the groove; a movable rod fixedly connected to the rectangular frame strip is movably connected to the movable hole; a sliding groove is provided on the lower inner wall of the inner side of the loading box; a sinking groove is provided through the front end of the sliding groove; and the movable rod is movably connected to the sliding groove and the sinking groove.

[0011] Preferably, the square frame strip is provided with pressure relief holes running through it vertically; the diameter of the pressure relief holes increases from bottom to top; the square frame strip is slidably sealed to the square frame groove; and the movable rod is movably sealed to the movable hole.

[0016] 1.

[0018] 3. In this invention, after the UAV body, carrying the loading box, lands on the landing platform, the drive plate moves upward, creating negative pressure in the lower cavity. The liquid medium inside the elastic bladder enters the lower cavity through the first air hole. As the liquid medium moves from a higher position to a lower position, the UAV body and the loading box become more stable during the parking process. After the loading of the materials is completed, the drive plate moves downward again, and the medium in the lower cavity enters the elastic bladder, causing the elastic bladder to bulge. The bulging elastic bladder faces the head direction during the formation of the UAV body. Thus, the bulging elastic bladder reduces wind resistance. Attached Figure Description

Detailed Implementation

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figures 1 to 13 As shown, the present invention includes the following embodiments:

[0036] Example 1: An emergency rescue drone includes a drone body 1 and a loading box 2 fixedly connected to the underside of the drone body 1; the front side of the loading box 2 is provided with an opening; a box door 3 is hinged to the upper part of the opening of the loading box 2 by a torsion spring 31; a driven groove 21 is vertically provided on the front side of the loading box 2; a driven plate 4 is slidably and sealingly connected to the driven groove 21; a support plate 5 is provided at the lower part of the opening of the loading box 2 and is fixedly connected to the driven plate 4; the inner side of the box door 3 is provided with a relief adapted to the support plate 5. The loading box 2 has a slidable groove 32; the bottom wall of the loading box 2 is slidably connected to a bearing plate 6 which is fixedly connected to a support plate 5; the bottom of the loading box 2 is provided with a drive groove 22; the drive groove 22 is slidably and sealed to a drive plate 7; the upper surface of the drive plate 7 is connected to the upper inner wall of the drive groove 22 by a first spring 71; the upper inner wall of the drive groove 22 is connected to the bottom of the driven groove 21 by a first liquid hole 23; the lower surface of the drive plate 7 is fixedly connected to a drive rod 72; the drive rod 72 passes downward through the bottom wall of the loading box 2.

[0037] An arc-shaped angle 41 is provided at the upper front end of the driven plate 4; the box door 3 flips open under the pressure of the arc-shaped angle 41 of the driven plate 4.

[0038] Under control, the drone body 1 moves the loading box 2 downwards. As the loading box 2 moves downwards, it approaches the landing platform. The loading box 2 then causes the lower end of the drive rod 72 to contact the landing platform. The drive rod 72, subjected to the platform's reaction force, moves upwards. The drive plate 7 moves upwards within the drive groove 22, dividing the drive groove 22 into an upper cavity and a lower cavity. During its upward movement, the drive plate 7 compresses the first spring 71. This compression of the upper cavity causes the liquid medium within it to... The liquid flows into the driven tank 21 through the first liquid hole 23. The liquid medium in the driven tank 21 will push the driven plate 4 and the support plate 5 forward. During the forward movement of the driven plate 4, the support plate 5 will also move forward. During the forward movement of the support plate 5, the box door 3 will be squeezed and opened against the torsion spring 31. The driven plate 4 will also squeeze the box door 3. The arc angle 41 at the upper front end of the driven plate 4 makes the box door 3 open slowly by squeezing, preventing it from opening too quickly and causing injury to the surrounding personnel. The slow opening can also protect and shield the materials on the support plate 6.

[0039] As the support plate 5 moves forward, it pulls the bearing plate 6 out of the bottom wall of the loading box 2. During this forward movement, the bearing plate 6 gradually moves away from directly below the belly of the drone body 1. After the lower end of the drive rod 72 is flush with the lower surface of the loading box 2, the drive plate 7 moves upward to its limit position, and the driven plate 4 moves forward to its limit position. Since the amount of liquid medium entering the driven groove 21 is limited, there is no situation where the driven plate 4 detaches from the driven groove 21. The bearing plate 6 moves from the center to the edge position below the drone body 1, thus eliminating the need for the operator to reach into the belly of the drone body 1 to retrieve or place materials. After the operator places the materials on the bearing plate 6, the drone body 1 starts and moves upward, causing the loading box 2 to move upward. The loading box 2 leaves the landing platform as the drone body 1 moves upward. The first spring 71 pushes the drive plate 7 downward, causing the drive rod 72 to gradually extend from the lower surface of the loading box 2. As the drive plate 7 moves downward, the space in the upper cavity gradually increases, creating a negative pressure. Under the action of the negative pressure, the liquid medium in the driven groove 21 flows back into the upper cavity along the first liquid hole 23. Under the action of the negative pressure, the driven plate 4 gradually retracts into the driven groove 21. As the driven plate 4 moves backward, it drives the support plate 5 and the bearing plate 6 to move backward. As the bearing plate 6 moves backward, it moves the material towards the inside of the loading box 2. The torsion spring 31 drives the box door 3 to flip downward as the driven plate 4 and the support plate 5 move backward. After the box door 3 flips, it covers the opening of the loading box 2. During transportation, the material is located inside the loading box 2, and the box door 3 blocks the opening of the loading box 2 under the action of the torsion spring 31. After the material is transported to the destination and lands on the landing platform, the drive rod 72 at the bottom of the loading box 2 is pressed again, driving the drive plate 7 to move upward in the drive groove 22, so that the bearing plate 6 moves the material out from the inside of the loading box 2, which facilitates the unloading of the material.

[0040] This invention controls the drive rod 72 after landing to be pressed, causing the drive plate 7 to move upward in the drive groove 22, thereby causing the driven plate 4 to move the bearing plate 6 out of the loading box 2 under hydraulic push, thus making the loading and unloading position of the materials closer to the lower edge of the UAV body 1, thereby improving the convenience of loading and unloading materials.

[0041] Example 2: An inverted L-shaped groove 33 is provided on the inner side of the box door 3, communicating with the lower end; a barb 34 is movably connected to the inverted L-shaped groove 33; the upper end of the barb 34 is connected to the upper end of the inverted L-shaped groove 33 by a second spring 35; the length of the lower end of the barb 34 extending out of the box door 3 is greater than the length of the drive rod 72 extending out of the bottom wall of the loading box 2; a positive hook block 24 is fixedly connected to the opening of the loading box 2 facing forward; the positive hook block 24 and the lower end of the barb 34 are engaged with each other; a first inclined surface 241 is provided at the front and upper position of the positive hook block 24; a second inclined surface 341 is provided at the rear lower position of the upper end of the barb 34.

[0042] As the drone body 1 moves the loading box 2 down to the landing platform, the lower end of the barb 34 contacts the landing platform first compared to the drive rod 72. The barb 34 slides along the inverted L-shaped groove 33 and compresses the second spring 35 to move upward. During the upward movement, the barb 34 disengages from the hook block 24, locking the barb 34 and the hook block 24, thus unlocking the box door 3. Subsequently, the drive rod 72, under pressure, moves the drive plate 7 upward. Under hydraulic pressure, the driven plate 4 moves the bearing plate 6 and the support plate 5 forward. The driven plate 4 and the support plate 5 overcome the pressure of the torsion spring 31 to open the box door 3. After loading and unloading the materials, the drone body 1 moves the loading box 2 upward, and the loading box 2 will... As the drive plate 7 moves away from the landing platform, it moves down along the drive groove 22 under the action of the first spring 71. The driven plate 4 drives the bearing plate 6 back into the loading box 2. The box door 3 flips back to its original position under the action of the torsion spring 31. During the return process of the box door 3, the barb 34 moves closer to the hook block 24. When the end of the barb 34 away from the second spring 35 has time to contact the landing platform, the end of the barb 34 away from the second spring 35 is pressed and slides in the inverted L-shaped groove 33, so that the upper end of the barb 34 passes over the hook block 24. When the lower end of the barb 34 is no longer in contact with the landing platform, the second spring 35 pushes the barb 34 down and locks it with the hook block 24, thus locking the box door 3.

[0043] If, during the return process of the door 3, the end of the hook bar 34 that is away from the second spring 35 does not have time to contact the landing platform, the second inclined surface 341 on the hook bar 34 contacts the first inclined surface 241, allowing the upper end of the hook bar 34 to move over the positive hook block 24 and, under the push of the second spring 35, the upper end of the hook bar 34 is locked with the positive hook block 24, thereby locking the door 3 and making the transportation of materials more stable.

[0044] Example 3: A support groove 51 is provided on the lower surface of the support plate 5; a support block 52 is slidably and sealed in the support groove 51; the support block 52 is connected to the bottom of the support groove 51 by a third spring 53; the bottom of the support groove 51 is connected to the rear end of the driven plate 4 through a second liquid hole 54.

[0045] The support plate 5 has multiple support grooves 51 on its lower surface; the support block 52 has rolling balls 55 on its lower surface.

[0046] After the drone body 1 and the loading box 2 land on the landing platform, the drive rod 72 will drive the drive plate 7 to slide and squeeze the upper cavity in the drive groove 22. The liquid medium in the upper cavity will flow into the driven groove 21 along the first liquid hole 23. The liquid medium in the driven groove 21 will flow into the support groove 51 along the second liquid hole 54. The support groove 51 is equipped with a third spring 53. The third spring 53 will push the support block 52 in the support groove 51 to move down and extend to abut against the landing platform.

[0047] Furthermore, there are multiple support grooves 51, so that multiple support blocks 52 can be used on uneven ground to ensure the stability of the support blocks 52 supporting the support plate 5. As the liquid medium in the driven groove 21 increases, the driven plate 4 will move forward under hydraulic action. During the forward movement of the driven plate 4, it will drive the support plate 5 to move forward. The support plate 5 will drive the support block 52 to move with the ground. The ball bearings 55 on the lower surface of the support block 52 can reduce the friction between the support block 52 and the ground, so that the support block 52 can move forward smoothly with the support plate 5. As the loading box 2 moves down, the length of the drive rod 72 extending out of the lower surface of the loading box 2 will gradually decrease. The support block 52 will retract into the support groove 51 as the loading box 2 moves down, and the driven plate 4 will also move forward further.

[0048] With the support of the support plate 5 and the support block 52, the materials can remain stable after the carrier plate 6 is moved out of the loading box 2, avoiding the situation where the materials and the drone body 1 will tip over due to the sinking of the end of the carrier plate 6 away from the loading box 2, thus improving the stability of the drone body 1 and the materials. After the materials on the carrier plate 6 are loaded and unloaded, the drone body 1 will control the loading box 2 to move upward, the drive plate 7 will move downward, the driven plate 4 will drive the carrier plate 6 to retract into the loading box 2, the driven plate 4 will retract into the driven groove 21, and the support block 52 will also retract into the support groove 51.

[0049] Example 4: A square frame groove 61 is provided on the upper surface of the bearing plate 6 near the edge; a square frame strip 8 is slidably connected up and down in the square frame groove 61; a movable hole 62 is provided through the bottom of the square frame groove 61; a movable rod 81, which is fixedly connected to the square frame strip 8, is movably connected in the movable hole 62; a sliding groove 25 is provided on the lower inner wall of the inner side of the loading box 2; a sinking groove 26 is provided through the front end of the sliding groove 25; the movable rod 81 is movably connected in the sliding groove 25 and the sinking groove 26.

[0050] The square frame strip 8 is provided with pressure relief holes 82 running through it from top to bottom; the diameter of the pressure relief holes 82 increases from bottom to top; the square frame strip 8 is slidably sealed to the square frame groove 61; the movable rod 81 is movably sealed to the movable hole 62.

[0051] After the drone body 1, carrying the loading box 2, lands on the landing platform, the drive rod 72 will move the drive plate 7 upward. The drive plate 7 will then move the driven plate 4 forward. During the forward movement of the driven plate 4, the support plate 5 and the bearing plate 6 will also move forward. During the forward movement of the bearing plate 6, the movable rod 81 will move along the slide groove 25. The lower end of the movable rod 81 will abut against the bottom of the slide groove 25. Therefore, the square strip 8, supported by the movable rod 81, will be in a state of protruding from the square groove 61. Since the upper surface of the bearing plate 6 protrudes from the square strip 8 near the edge, the material on the upper surface of the bearing plate 6 can be moved out of the loading box 2 as the bearing plate 6 moves forward, limited by the square strip 8. During the forward movement of the bearing plate 6, the movable rod 81... Still within the range of the chute 25, the frame bar 8 will continuously limit and protect the materials during the forward movement. When the support plate 6 moves to its limit position, the support plate 6 will also drive the movable rod 81 to move out of the chute 25 and directly above the sinking trough 26. Under its own gravity, the frame bar 8 will drive the movable rod 81 to move down. The movable rod 81 will gradually enter the sinking trough 26 to avoid obstacles. Since the frame bar 8 and the frame groove 61 are slidably sealed, the frame bar 8 will squeeze the gas in the frame groove 61 during the downward movement, so that the gas in the frame groove 61 will be discharged along the pressure relief hole 82. Since the diameter of the pressure relief hole 82 is limited, the pressure relief hole 82 has a limited speed of unloading the gas in the frame groove 61.

[0052] This causes the rectangular strip 8 to slowly move downwards, which also serves to limit the movement of materials, preventing them from detaching from the support plate 6 due to inertia. As the rectangular strip 8 slowly retracts into the rectangular groove 61, its upper surface becomes flush with the upper surface of the support plate 6. Without the restraint of the rectangular strip 8, materials on the upper surface of the support plate 6 are easier to unload and reload. After loading new materials, the support plate 6 moves backwards, causing the movable rod 81 to move from the sinking groove 26 into the sliding groove 25. The transition area between the sinking groove 26 and the sliding groove 25 is set at a certain... The slope is designed to facilitate the movement of the movable rod 81 from the sinking trough 26 into the sliding trough 25. As the movable rod 81 enters the sliding trough 25, it moves upward and moves along the movable hole 62, causing the square frame bar 8 to move upward. The square frame bar 8 moves upward along the square frame groove 61, and external gas enters the square frame groove 61 through the pressure relief hole 82 for replenishment. The diameter of the pressure relief hole 82 increases from bottom to top, so the gas enters the square frame groove 61 more quickly, reducing the resistance of the movable rod 81 moving backward. The square frame bar 8 protrudes from the upper surface of the bearing plate 6 near the edge, so that the materials are more stably delivered into the loading box 2 after being limited, improving the stability of the material loading.

[0053] In this embodiment, a square frame strip 8 protrudes from the upper surface of the support plate 6 near the edge. During the loading and unloading process of the support plate 6, the square frame strip 8 is controlled to retract into the square frame groove 61, thereby making the materials more stable during the back-and-forth movement of the support plate 6, and also making the loading and unloading process of the materials more convenient.

[0054] Example 5: An elastic bladder 27 is fixedly connected to the rear side of the loading box 2; the elastic bladder 27 is connected to the lower inner wall of the drive groove 22 through the first air hole 28; the drive rod 72 is movably and sealingly connected to the loading box 2.

[0055] The loading box 2 has clamping bladders 29 symmetrically arranged on its left and right inner walls; the clamping bladders 29 are connected to the elastic bladder 27 through the second air hole 291; the elasticity of the clamping bladder 29 is greater than that of the elastic bladder 27.

[0056] After the drone body 1 and the loading box 2 land on the landing platform, the drive plate 7 moves upward, creating negative pressure in the lower cavity. The liquid medium in the elastic bladder 27 enters the lower cavity through the first air hole 28. As the liquid medium moves from a high position to a low position, the drone body 1 and the loading box 2 become more stable during the parking process. After the loading of the materials is completed, the drive plate 7 moves downward again, and the medium in the lower cavity enters the elastic bladder 27, causing the elastic bladder 27 to inflate. The inflated elastic bladder 27 is in the head direction during the formation of the drone body 1. Thus, the inflated elastic bladder 27 reduces wind resistance.

[0057] Furthermore, clamping bladders 29 are symmetrically arranged on the left and right inner walls of the loading box 2. During the journey, the wind resistance of the elastic bladder 27 will compress the medium inside the elastic bladder 27 and allow it to enter the clamping bladder 29 through the second air hole 291. This allows the symmetrical clamping bladders 29 to clamp the internal materials, preventing them from shaking during transportation and improving the stability of the transportation. After the drone body 1 moves the loading box 2 to the landing platform, the elastic bladder 27 is no longer subject to wind resistance. The elasticity of the clamping bladder 29 will press the medium inside the clamping bladder 29 into the elastic bladder 27 through the second air hole 291. After the clamping bladder 29 deflates, it releases the clamp on the materials, allowing the materials to be smoothly carried out of the loading box 2 by the carrying plate 6.

[0058] Example 6: The left and right outer sides of the loading box 2 are provided with protective frames 11 that are fixedly connected to the drone body 1; the lower end of the protective frame 11 is not lower than the lower surface of the loading box 2.
