Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned aerial vehicles (UAVs), and in particular relates to an all-terrain rescue UAV. Background Art

[0002] Drone technology was initially used primarily in the military, for reconnaissance and surveillance missions. With technological advancements and reduced costs, drones have gradually been adopted in civilian applications, including agriculture, logistics, surveying and mapping, security, and power inspections. In the field of emergency rescue, drones have become an indispensable tool, as they can quickly reach complex terrain and dangerous areas, provide real-time information, and deliver supplies.

[0003] Limitations of existing drones in rescue operations: Despite their numerous advantages, drones still face numerous challenges in complex terrain. Traditional drones, mostly fixed-wing or rotary-wing, struggle to maintain stable takeoff and landing, and to fly steadily over rugged terrain. For example, in mountainous areas, forests, and urban ruins, drones are easily affected by factors such as undulating terrain, obstructed by trees, and building debris, leading to unstable flight and even crashes. Furthermore, existing drones have limited battery life, requiring frequent battery replacement and recharging during extended rescue missions, impacting rescue efficiency.

[0004] The necessity of all-terrain rescue drones: To overcome the limitations of traditional drones in complex terrain, all-terrain rescue drones have emerged. All-terrain rescue drones need to possess greater adaptability, enabling stable takeoff and landing and flight on a variety of terrains. This includes achieving self-balancing takeoff and landing on uneven surfaces, as well as the ability to flexibly adjust their posture during flight to avoid obstacles. At the same time, all-terrain rescue drones also need to have longer flight endurance to meet the needs of long-term rescue missions. Furthermore, to obtain accurate information in complex rescue environments, all-terrain rescue drones must be equipped with advanced sensors and cameras, such as infrared thermal imagers, high-definition cameras, and lidar, to enable real-time monitoring of disaster areas, disaster assessment, and personnel search and rescue and location tracking.

[0005] While some all-terrain drone technology has been researched and patents have been filed, some shortcomings remain. For example, some all-terrain drones are overly complex in design, resulting in high manufacturing costs and hindering large-scale deployment. Furthermore, the control systems of some all-terrain drones are inadequate, leaving room for improvement in their ability to make autonomous decisions and respond to complex terrain and emergencies. Furthermore, existing all-terrain drone communication systems exhibit issues with signal transmission stability in complex environments, potentially hindering information transmission between the drone and ground control centers, thereby impacting the smooth progress of rescue missions. Summary of the Invention

[0038] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the detailed description of the embodiments of the present invention provided below is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0040] Example:

[0041] like Figures 1-11As shown, an all-terrain rescue drone includes a body 1 and a rescue cabin 2. The rescue cabin 2 is arranged on the top of the body 1. A telescopic support rod 61 is provided between the lower front end of the rescue cabin 2 and the body 1 for tilting the rescue cabin 2 rearward. The rear part of the rescue cabin 2 is an entrance and an exit and is provided with a cabin door 21. A basket stretcher 6 is provided in the rescue cabin 2. A telescopic base frame 62 is provided between the basket stretcher 6 and the interior of the rescue cabin 2. The basket stretcher 6 is placed on a movable frame 621 of the telescopic base frame 62. The telescopic direction of the telescopic base frame 62 is provided along the entrance and exit direction of the rescue cabin 2 exit and is used to extend or retract the basket stretcher 6 into the rescue cabin 2. The movable frame 621 close to the exit side of the rescue cabin 2 is rotatably connected to the stretcher telescopic leg 63 for ground support after the stretcher is extended from the rescue cabin 2. The telescopic support rod 61 utilizes a four-section structure to fit within the space. This simple lifting mechanism is located at each end on the frame 11 of the body 1 and the rescue capsule 2. It is also pivotally mounted to allow for deflection during lifting, which will not be further elaborated. Upon arrival at the designated rescue location, the rescue capsule 2 is extended, tilting the support rod. The basket stretcher 6 is moved to the appropriate position via the telescopic base 62, which then locks the basket stretcher 6 into position, providing longitudinal positioning. The hatch 21 is openable and closable, allowing for the basket stretcher 6 to be removed and inserted.

[0042] like Figure 7 and Figure 8 As shown, the telescopic base frame 62 includes a mobile frame 621 and a telescopic arm 622, and the telescopic arm 622 is respectively connected to the mobile frame 621 and the inner wall of the rescue cabin 2. A positioning block 64 is provided on the mobile frame 621, and a positioning groove corresponding to the positioning block 64 is provided at the bottom of the basket stretcher 6 for positioning the basket stretcher 6 and fixing it during telescoping. That is, the mobile frame 621 moves with the basket stretcher 6, and the mobile frame 621 can move a long distance driven by the telescopic arm 622. Of course, the mechanism of the mobile frame 621 and the telescopic arm 622 is not specifically limited. For example, the mobile frame 621 can be a slider and the telescopic arm 622 can be a slide rail or other similar mechanism for achieving displacement.

[0043] like Figure 7As shown, the mobile frame 621 of the telescopic chassis 62 is connected to a rotating mechanism 631 at the end near the exit of the rescue chamber 2. This rotating mechanism 631 is connected to the telescopic stretcher legs 63. The lower portion of the telescopic stretcher legs 63 is provided with a first universal footplate 632. The rotating mechanism 631 is primarily used to rotate the mobile frame 621 and telescopic arm 622 to adapt to ground conditions. The rotation angle is controlled by a main control box 7, which sets parking parameters based on a scanned ground model. Of course, corresponding pressure sensors and other auxiliary equipment are also required to ensure that the ground is supportable to prevent the ground from being too soft to bear the load, which will not be further described here. The first universal footplate 632 provides stable support for the drone when on the ground, preventing it from tipping over. The telescopic stretcher legs 63 in this embodiment adopt a three-section structure, which can be folded short for easy storage inside the rescue chamber 2. The rotation plane of the rotating mechanism 631 is actually parallel to the telescopic plane of the telescopic chassis 62, that is, it is used to adjust the angle between the telescopic chassis 62 and the telescopic stretcher legs 63.

[0044] The body 1 includes a frame 11, a blade mechanism 12, a telescopic leg mechanism 13, and a landing telescopic leg 14 (the blade mechanism 12, the telescopic leg mechanism 13, and the landing telescopic leg 14 constitute an arm leg mechanism, which can achieve landing on uneven ground). The front end of the telescopic leg mechanism 13 is rotatably installed with the frame 11 on a horizontal plane, and the blade mechanism 12 is installed on the upper part of the rear end of the telescopic leg mechanism 13. The frame 11 is equipped with four sets of blade mechanisms 12 through four telescopic leg mechanisms 13 to form a quadcopter. Four telescopic leg mechanisms 13 are located at the lower rear end of the telescopic leg mechanism 13, corresponding to the paddle mechanisms 12. The paddle mechanisms 12 include a motor 121 and paddles 122. The motor 121 is mounted on the rear end of the telescopic leg mechanism and connected to the paddles 122. The landing telescopic leg 14 includes a telescopic leg 141 and a second universal footplate 142. The telescopic leg 141 is mounted vertically downward, with the second universal footplate 142 mounted at the lowest end. Navigation lights 16 are located on the outer ends of the telescopic leg mechanisms 13. The telescopic leg mechanisms 13 are retractable and adjustable in length to suit the terrain. The second universal footplate 142 provides stable support for the drone when on the ground, preventing it from tipping over. It also absorbs some impact during landing, providing cushioning and shock absorption, allowing for flexible adaptation to different terrains. The landing telescopic leg 14 is retractable and adjustable in length to suit the terrain. The motor 121 powers the paddles 122, driving their rotation and controlling their flight attitude. The navigation lights 16 allow the operator or ground personnel to clearly identify the drone's position, especially at long distances or in low-light environments, enabling quick positioning and enhancing visibility. The telescopic leg mechanism 13 utilizes a two-stage structure, while the landing telescopic leg 14 utilizes a three-stage structure. The number of stages can be flexibly adjusted to meet operational requirements.

[0045] like Figure 8As shown, the upper portion of the frame 11 is in a groove shape, in which the rescue cabin 2 is placed, an airbag 31 is provided between the groove of the frame 11 and the rescue cabin 2, and a pop-up device 32 is provided between the rescue cabin 2 and the frame 11. Figure 9 As shown, the pop-up device 32 includes a base 321 and a strong support rod 322. The base 321 is installed on the frame 11, and the strong support rod 322 is installed in the base 321 and contacts the rescue cabin 2. The pop-up device 32 and the airbag 31 constitute the escape system 3. In the present invention, the groove of the frame 11 is a flat V-shaped with the lower part of the oblique sides on both sides horizontal. Therefore, the rescue cabin 2 adopts an octagonal cross-section shape, which can fit the groove of the frame 11. At the same time, the structure of the rescue cabin 2 is also more beautiful. The space is also more regular, and the right-angled edges are avoided, which is conducive to the side coverage of the airbag, forming Figure 11 In the structure shown, it can be seen that the strong support rod 322 has been deployed, ejecting the rescue capsule 2 from the drone. The airbag then deploys to cover the sides of the rescue capsule 2, reducing the impact of the fall. In practice, the rescue capsule 2 is connected to the frame via a telescopic support rod 61 at the rear end and a rotating shaft at the front that facilitates the lifting of the rescue capsule 2. The rotating shaft is broken by the strong support rod 322, and the telescopic support rod 61 is unlocked using a locking structure to automatically eject. A physical pull rod can also be provided inside the capsule to disengage it. This technology is relatively simple and will not be described in detail here.

[0046] like Figure 2 As shown, the aircraft body 1 is equipped with a bottom compartment 15, which houses a first battery compartment 151, a second battery compartment 152, and a main control box 7. Externally, the bottom compartment 15 is equipped with a laser radar 51, a fresh air subsystem air inlet 431, a smoke detector 52, a camera 53, and a supporting gimbal 531. The first battery compartment 151 and the second battery compartment 152 on the side of the bottom compartment serve as the main battery compartment and the backup battery compartment, respectively, housing the main battery. The main battery is used during normal flight, while the backup battery is used in emergencies such as a power outage in the main battery compartment. The camera 53 and gimbal 531 are used for image acquisition, real-time monitoring, angle adjustment, and image stabilization. The laser radar 51 is used for terrain mapping, quickly and accurately acquiring topographic data. For environmental monitoring, it scans forest and vegetation cover, monitoring vegetation height and density. The smoke detector 52 is used for smoke detection, quickly determining smoke spread and concentration, and assisting in rescue operations. The fresh air subsystem 43 is activated based on detection or manual activation to adjust the air environment inside the drone, continuously renewing the internal air and maintaining a good internal air condition. The location of the fresh air subsystem air inlet 431 is where the equipment of the fresh air subsystem is located.

[0047] The rescue cabin 2 is equipped with an oxygen cylinder 41, an air conditioning compressor 421, a rescue material compartment, a ventilation device 44, and an air conditioning outlet 422. The rescue material compartments, ranging from small to large, are used to store rescue materials and tools. Any space available that does not affect the safe operation of the drone can accommodate a material compartment. The oxygen cylinder 41 is used for medical emergency and auxiliary rescue operations, and can also be used for emergency oxygen supply within the rescue cabin 2. Additional emergency oxygen cylinders or chemical oxygen supplies can also be installed within the rescue cabin 2 as a backup oxygen supply during escape. Of course, the rescue cabin 2 can also be equipped with other necessary rescue equipment, which can be installed as needed and will not be detailed here. A ventilation device 44 is installed at the top of the rescue cabin 2 to continuously expel harmful gases that accumulate on the ground. This facilitates rapid air renewal within the cabin, creating a slightly positive pressure and preventing the entry of harmful gases caused by fire. The ventilation device 44 can be operated as needed to vent air. When the positive pressure is maintained, it can be stopped. Alternatively, a cover can be used to seal the ventilation device 44 channel to reduce the possibility of harmful gases entering the rescue cabin 2.

[0048] Of course, this embodiment Figure 6 It can be seen that the oxygen cylinder 41 and the compressor 421 of the air-conditioning subsystem 42 are arranged in the groove on the side of the frame 11, which can be easily replenished and protected. The groove on the side of the frame 11 can also be used to form storage space, rescue supplies storage, etc., which can be flexibly arranged and will not be repeated here.

[0049] The rescue cabin 2 has a positive pressure system 4, which includes an oxygen cylinder 41, an air conditioning subsystem 42, and a fresh air subsystem 43. The oxygen cylinder 41 is used to provide oxygen for rescue and emergency oxygen supply to the rescue cabin 2. If the rescue cabin 2 needs to pass through an oxygen-deficient area, such as a fire or other environment requiring a closed rescue cabin 2 without access to external air, the air conditioning subsystem 42 controls the temperature, while the fresh air subsystem 43 is used to input fresh air and generate positive pressure. The oxygen cylinder 41 is used for emergency oxygen supply, while the air conditioning compressor 421 of the air conditioning subsystem 42 adjusts the cooling or heating intensity to achieve a set temperature, providing a suitable temperature environment for the injured. The air conditioning outlet 422 coordinates air circulation within the cabin, while the fresh air subsystem 43 provides clean air inside the rescue cabin 2, primarily acting as an air filter. It is primarily used in fire environments where the external air is thick with smoke or other similarly polluted environments. For other environments with toxic gases, a specific fresh air subsystem 43 should be installed. If necessary, the rescue cabin 2 should be fully sealed to completely isolate the outside environment. To facilitate the ejection of the rescue capsule 2, the air conditioning subsystem 42 is actually mounted on the frame 11. Air supply is achieved simply by connecting the air conditioning outlet 422, located in the upper recess of the base frame, to the air conditioning outlet on the rescue capsule 2. The air conditioning outlet on the rescue capsule 2 also serves as the air inlet for the fresh air subsystem entering the rescue capsule 2. This relatively large outlet can be understood as functioning as both an air conditioning outlet and a fresh air outlet by partitioning the outlet. If necessary, the air conditioning outlet on the rescue capsule 2 can be sealed to maintain the overall tightness of the rescue capsule 2.

[0050] A main control box 7 is provided. This box is electrically connected to the telescopic support rod 61, telescopic chassis 62, rotating device 631, telescopic stretcher legs 63, blade mechanism 12, telescopic leg mechanism 13, telescopic landing legs 14, escape system 3, positive pressure system 4, and environmental monitoring system 5. The main control box 7 is used to receive data from the environmental monitoring system 5 to control the operation of the telescopic support rod 61, telescopic chassis 62, rotating device 631, telescopic stretcher legs 63, blade mechanism 12, telescopic leg mechanism 13, telescopic landing legs 14, escape system 3, and positive pressure system 4. The main control box 7 is used to control flight attitude, manage the power system, process signals and execute commands, and monitor the drone's status in real time to ensure safety.

[0051] Usage: When conducting emergency rescue, the drone flies to the designated rescue location, the bottom cabin camera and its gimbal perform visual recognition to determine the location of the rescue personnel, the laser radar detects the ground conditions below the all-terrain rescue drone, and the telescopic legs are extended to different lengths to land at the nearest point to reach the rescue personnel. The rescue cabin door opens, the rescue cabin tilts through the telescopic support rod, and then the basket stretcher is extended through the telescopic base frame. The stretcher telescopic legs are extended to different heights to adapt to uneven ground, forming a Figure 5In the form shown, after the rescued person is lifted and placed on the basket stretcher, the telescopic chassis drives the basket stretcher to reset. The rescue cabin returns to its position, the hatch closes, and the air-conditioning compressor adjusts the cabin temperature through the air-conditioning outlet. The oxygen cylinder provides oxygen to the rescued person, and the ventilation device updates the cabin air through the air inlet of the bottom cabin fresh air system. The motor drives the blades to rotate, the drone takes off, and when it arrives at the designated location, the doors of the rescue cabin open and the rescued person is released. After the rescue cabin is closed, the drone takes off again for the next rescue. The standby form is as follows Figure 5 shape, which can be convenient for transportation, etc.

[0052] When the drone encounters an emergency, the escape system works and the strong support rod of the pop-up device pops out, forcibly separating the rescue capsule from the main body of the fuselage. After the rescue capsule is separated from the main body of the fuselage, the airbags on both sides of the rescue capsule pop open, wrapping the rescue capsule to reduce the impact of falling.

[0053] This drone is mainly used for short-distance rescue in harsh natural environments. It only needs to fly from dangerous areas to safe areas. Therefore, the flight altitude only needs to avoid obstacles, so its flight altitude will not be too high. If high-altitude flight is required, you can consider configuring a parachute to reduce the impact on the rescue capsule.
