Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to an amphibious rescue UAV. Background Technology

[0002] Currently, earthquakes, tsunamis, volcanic eruptions, torrential rains, cold waves, freezing rains, high temperatures, droughts, and mudslides pose serious threats to people's lives and property. Therefore, whenever a disaster or accident occurs, timely rescue of the injured or trapped is necessary. Especially in the face of floods or drowning accidents in deep water, traditional rescue methods are often limited by factors such as time, terrain, and manpower, resulting in a slow response time. The "golden rescue time" for drowning victims is only four to six minutes, and traditional rescue methods are inefficient and prone to missing the optimal rescue window.

[0003] With the continuous development of technology, drones have been widely used in various fields. In particular, drones possess advantages such as rapid response, wide visibility, no terrain limitations, and remote control, making them particularly effective in rescue operations. However, existing drones can only fly in the air and cannot operate on or underwater, limiting their application in scenarios such as maritime search and rescue, marine environmental monitoring, and underwater exploration. This results in existing drones having limited functionality and being unable to simultaneously meet the needs of both air and water navigation. Therefore, there is currently a lack of drones capable of flexibly switching between air and water environments for efficient rescue operations. Utility Model Content

[0004] The purpose of this invention is to provide an amphibious rescue drone to solve the problem that existing drones cannot simultaneously meet the needs of air flight and water navigation.

[0013] Optionally, both the first blade and the second blade include a base blade, a receiving blade, and an extension blade. The base blade is connected to the propeller shaft. The receiving blade is integrally formed with the outer end of the base blade, and a receiving groove is provided on the outer end face of the receiving blade. The extension blade is fitted into the receiving groove. A fourth driver is provided in the receiving groove. The output end of the fourth driver is connected to the extension blade and is used to drive the extension blade to perform linear reciprocating motion along the receiving groove.

[0014] Optionally, the amphibious rescue drone also includes a main control unit, a detection unit, and a communication unit;

[0015] The communication unit is electrically connected to the main control unit and is used for data exchange between the main control unit and the ground terminal.

[0018] Compared with the prior art, the amphibious rescue drone provided in this embodiment of the present invention has the following advantages:

[0019] By configuring an amphibious rescue drone composed of aquatic and aerial components, it can operate in three modes: retractable, aquatic, and aerial. In retractable mode, the inflatable air cushion deflates and folds, and is stored within the first and second storage housings. In aerial mode, the first and second wings are aligned in a cross shape, and propellers at both ends of the wings evenly distribute propeller power in four directions, enhancing flight stability. Upon contact with water, the inflatable air cushion deploys, activating the drone in aquatic mode. The air cushion floats on the water, and propellers on the first and second wings generate thrust in front of and behind the air cushion, propelling the drone forward. This allows amphibious rescue drones to share a single, convertible wing and propeller assembly in both air and water modes, maximizing their effectiveness in both flight and water navigation, achieving rapid rescue, effectively saving rescue manpower, and shortening water rescue time.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] This utility model discloses an amphibious rescue drone, such as Figures 1-3 As shown, the amphibious drone includes an aquatic component 1 and an amphibious component 2. The aquatic component 1 includes a first storage shell 11, a second storage shell 12, and an inflatable air cushion 13 connecting the first and second storage shells 11 and 12. The first and second storage shells 11 and 12 are joined to form a box structure for housing the inflatable air cushion 13. Upon contact with the water surface, the amphibious rescue drone inflates and deploys the air cushion 13 to achieve its aquatic form. The amphibious component 2 includes a first wing 21 connected to the first storage shell 11 and a second wing 22 connected to the second storage shell 12. Propeller assemblies 23 are provided at both ends of the first and second wings 21 and 22. The first wing 21 or the second wing 22 is rotatable, and after rotation, the first wing 21 and the second wing 22 switch from a parallel structure to a cross-shaped structure to achieve their amphibious form.

[0030] Through the implementation of the aforementioned amphibious rescue drone, the aquatic component 1 and the airborne component 2 enable the amphibious rescue drone to possess three modes: storage, aquatic, and airborne. That is, when the amphibious rescue drone needs to be changed to storage mode (see reference...), Figure 2 Rescuers deflate and fold the inflatable air cushion 13, then dock the first storage shell 11 and the second storage shell 12, allowing the inflatable air cushion 13 to be stored within them. This completes the storage of the amphibious rescue drone. When the amphibious rescue drone needs to be converted to an aerial configuration (see reference...), Figure 3 The first wing 21 and the second wing 22 are adjusted to a cross-shaped structure. Using the propeller assemblies 23 at both ends of the first wing 21 and the second wing 22, propeller power is evenly distributed in four directions on the amphibious rescue drone, ensuring greater stability during flight. When the amphibious rescue drone needs to change to aquatic mode (see reference...), Figure 1Upon detecting contact between the amphibious rescue drone and the water surface, the system automatically activates the air source to inflate the air cushion 13, causing it to expand and separate the first storage shell 11 and the second storage shell 12 until the air cushion 13 is fully inflated and floats on the water. At this point, the first wing 21 and the second wing 22 are adjusted to a parallel structure, allowing the propeller assemblies 23 on the first wing 21 and the second wing 22 to generate thrust at the front and rear of the air cushion 13, stably propelling it forward. This allows the amphibious rescue drone to share a single set of convertible wings and propeller assemblies 23 in both airborne and waterborne modes, maximizing its effectiveness in both flight and water navigation, achieving rapid rescue, effectively saving rescue manpower, and shortening water rescue time.

[0031] Furthermore, combined Figure 4 As shown, both the first wing 21 and the second wing 22 include a wing body 24 and rotor arms 25 disposed at both ends of the wing body 24. A first driver 14 is disposed on the first storage housing 11 or the second storage housing 12, and the output end of the first driver 14 is connected to the corresponding wing body 24 to drive the wing body 24 to rotate. A propeller assembly 23 is disposed on the rotor arm 25, and when the amphibious rescue drone is in airborne mode, the first wing 21 is positioned parallel above the second wing 22.

[0032] Through the implementation of the amphibious rescue drone described above, utilizing the wing body 24 and the propeller arms 25 at both ends of the wing body 24, after the wing body 24 is connected to the corresponding first storage shell 11 or second storage shell 12, the propeller arms 25 at both ends are located in two opposite directions on the same plane of the amphibious rescue drone, and the propeller assemblies 23 on the propeller arms 25 provide flight power to the amphibious rescue drone at both ends of the wing body 24. At this time, the first driver 14 drives the wing body 24 to rotate, realizing adaptive deformation control of the rotation of the wing body 24, and after the first wing 21 or the second wing 22 rotates 90°, the first wing 21 is parallel to the second wing 22 and forms a cross structure, so as to uniformly generate flight power in four directions on the same plane of the amphibious rescue drone, ensuring the stable flight of the amphibious rescue drone. Preferably, the first driver 14 is a conventional drive device such as a micro motor or a micro servo motor.

[0033] Furthermore, looking back Figure 3The propeller arm 25 includes a first horizontal portion 251, a second horizontal portion 252, and an arc-shaped portion 253 connecting the first horizontal portion 251 and the second horizontal portion 252. The first horizontal portion 251 is connected to the end of the wing body 24, and both the first wing 21 and the second wing 22 form a "U"-shaped structure. When the first storage housing 11 and the second storage housing 12 are docked, the corresponding second horizontal portions 252 of the first wing 21 and the second wing 22 are fitted together. The propeller assembly 23 is located on the second horizontal portion 252.

[0034] Through the implementation of the amphibious rescue drone described above, the propeller arm 25 is divided into a first horizontal section 251, a second horizontal section 252, and an arc-shaped section 253. The structure of the arc-shaped section 253 allows the first horizontal section 251 and the second horizontal section 252 to be located on different planes. Since a first storage housing 11 and a second storage housing 12 are also provided between the first wing 21 and the second wing 22, the propeller arm 25 structure, after the first horizontal section 251 of the propeller arm 25 is connected to the end of the wing body 24, utilizes the transition structure formed by the inward bending of the arc-shaped section 253 to ensure that the corresponding second horizontal sections 252 of the first wing 21 and the second wing 22 can fit together completely without being affected by the first storage housing 11 and the second storage housing 12. This significantly reduces the space occupied by the first wing 21 and the second wing 22 when the amphibious rescue drone is in its stowed state, thus facilitating the carrying of the amphibious rescue drone and extending the application possibilities of the amphibious rescue drone of this utility model embodiment.

[0035] Further, if Figure 4 As shown, a second actuator 241 is provided inside the end of the wing body 24. The output end of the second actuator 241 is connected to the first horizontal part 251 of the corresponding rotor arm 25 to drive the rotor arm 25 to rotate. When the amphibious rescue drone is in aquatic mode, the first wing 21 and the second wing 22 are parallel to each other on opposite sides of the inflatable air cushion 13, and the openings of the first wing 21 and the second wing 22 are opposite to each other.

[0036] Through the implementation of the amphibious rescue drone described above, when the amphibious rescue drone is in its stowed state, the second horizontal sections 252 corresponding to the first wing 21 and the second wing 22 are in a fitted state. Furthermore, when the amphibious rescue drone is in its airborne state, although the second horizontal sections 252 corresponding to the first wing 21 and the second wing 22 are offset, when the amphibious rescue drone switches from airborne to waterborne state, it is still necessary to first adjust the first wing 21 and the second wing 22 to a parallel state. When the second horizontal sections 252 corresponding to the first wing 21 and the second wing 22 are in a fitted state, their mutual interference is detrimental to the deployment of the inflatable air cushion 13 and may also cause damage to the second horizontal sections 252 of the first wing 21 and the second wing 22. Therefore, by using the second actuator 241, the rotation of the propeller arms 25 can be adaptively deformed and controlled, causing the propeller arms 25 of the first wing 21 and the second wing 22 to rotate 180° until the openings of the first wing 21 and the second wing 22 are relatively opposite. At this time, the second horizontal sections 252 corresponding to the first wing 21 and the second wing 22 are relatively far apart, ensuring a sufficient safety distance. Then, the inflatable air cushion 13 is inflated and deployed to provide space for the rescued personnel. Simultaneously, utilizing the aforementioned deformation configuration of the rotating propeller arm 25, when the amphibious rescue drone is in its aquatic configuration, the propeller assemblies 23 on the first wing 21 and the second wing 22 provide thrust in the forward and backward directions of the inflatable air cushion 13. This allows for a larger spacing between the propeller assemblies 23 in front of and behind the inflatable air cushion 13, reducing mutual interference and preventing mutual influence from turbulence. This allows for stronger thrust between the propeller assemblies 23 in front of and behind the inflatable air cushion 13, thereby improving propulsion efficiency. Preferably, the second actuator 241 is a conventional drive device such as a micro motor or a micro servo.

[0037] Furthermore, combined Figure 3 and Figure 5 As shown, a propeller mounting hole is provided on the second horizontal section 252. The propeller assembly 23 includes a third driver disposed in the propeller mounting hole, a propeller shaft 231 connected to the output shaft of the third driver, and a first blade 232 and a second blade 233 stacked on the propeller shaft 231 within the propeller mounting hole. Multiple first blades 232 and second blades 233 are respectively arranged along the circumferential direction of the propeller shaft 231, and the number of first blades 232 and second blades 233 is different.

[0038] Through the implementation of the amphibious rescue UAV described above, the propeller shaft 231 is driven to rotate by a third drive, which in turn drives the stacked first blades 232 and second blades 233 to rotate synchronously. The multiple stacked first blades 232 and second blades 233 rotate in synergy to improve propulsion efficiency, providing higher lift during aerial flight and greater thrust during water navigation. Furthermore, if one set of blades fails, the other set can continue operating, improving system reliability. In addition, the different numbers of first blades 232 and second blades 233 can enhance the overall efficiency of the propulsion system. More blades may provide stronger thrust, while fewer blades provide more stable efficiency at high speeds. Preferably, along the direction of travel of the amphibious rescue UAV on the water, the two sets of blades consist of six in the front and four in the rear. The six front blades provide more thrust to overcome water resistance and wave effects, while the four rear blades maintain a stable course and speed, thus providing superior propulsion for the amphibious rescue UAV in water. Preferably, the third driver is a conventional drive device such as a micro motor.

[0039] Furthermore, both the first blade 232 and the second blade 233 include a base blade 234, a receiving blade 235, and an extension blade 236. The base blade 234 is connected to the propeller shaft 231. The receiving blade 235 is integrally formed with the outer end of the base blade 234, and a receiving groove is provided on the outer end face of the receiving blade 235. The extension blade 236 is fitted into the receiving groove, and a fourth actuator is provided in the receiving groove. The output end of the fourth actuator is connected to the extension blade 236 to drive the extension blade 236 to perform linear reciprocating motion along the receiving groove.

[0040] Through the implementation of the amphibious rescue UAV described above, a receiving blade 235 and an extension blade 236 are added to the basic blade 234. A fourth actuator drives the extension blade 236 to extend from the receiving blade 235, thereby increasing the length of the first blade 232 and the second blade 233. Alternatively, the fourth actuator can drive the extension blade 236 to retract into the receiving blade 235 to maintain the first blade 232 and the second blade 233 at their initial lengths. In practical applications, when the amphibious rescue UAV is flying in the air, it requires greater lift, thus requiring larger first blades 232 and 233 to provide sufficient lift. In this case, the fourth actuator drives the extension blade 236 to extend from the receiving blade 235. However, when the amphibious rescue UAV is navigating in water, the required thrust is lower than when airborne. Therefore, smaller first blades 232 and 233 can be used to reduce the load on the fourth actuator. In this case, the fourth actuator drives the extension blade 236 to retract into the receiving blade 235. This allows for adaptive control of the length changes of the first blade 232 and the second blade 233 based on the shape of the amphibious rescue drone, thus meeting the operational needs of amphibious rescue drones with different shapes and achieving maximum performance optimization. Preferably, the fourth actuator is a linear stroke actuator such as a miniature electric actuator.

[0041] Furthermore, the amphibious rescue drone also includes a main control unit, a detection unit, and a communication unit. The communication unit is electrically connected to the main control unit and is used for data exchange between the main control unit and the ground terminal. The detection unit includes a GPS positioning module and an attitude sensor. The GPS positioning module, attitude sensor, first driver 14, second driver 241, third driver, and fourth driver are all electrically connected to the main control unit.

[0042] In the implementation of the amphibious rescue drone described above, the main control unit is used for program execution and data processing, and can preferably be a microcontroller such as an STM32, Arduino Mega, or Raspberry Pi. The communication unit connects to the main control unit via a serial communication interface, enabling the main control unit to send and receive data, such as control commands and sensor detection data, through the communication unit. The communication unit can preferably use an ESP8266 or ESP32 Wi-Fi module, or a 4G module such as the SIM800L. The GPS positioning module is used to obtain the global positioning of the amphibious rescue drone, and can preferably be a u-blox NEO-6M GPS module. Attitude sensors are used to measure the drone's orientation, attitude, and acceleration. These can preferably be gyroscopes, accelerometers, or magnetometers. The main control unit connects to the GPS positioning module and attitude sensor via interfaces such as GPIO or SPI to receive data from the detection unit, such as position, speed, and attitude information. It then controls the first driver 14, the second driver 241, the third driver, and the fourth driver via PWM signals to adjust their power, thereby controlling the rotation of the wing body 24, the rotor arm 25, the propeller blades, and the extension and retraction of the extension blade 236. This enables the amphibious rescue drone to perform automated tasks, such as automatic takeoff, landing, and configuration switching, and allows rescue personnel to remotely receive real-time data, enabling rapid decision-making during rescue operations and improving efficiency and safety. Preferably, the amphibious rescue drone of this embodiment can also be equipped with an existing autonomous navigation system, capable of automatically planning the optimal path based on preset mission objectives and environmental information, further improving rescue efficiency.

[0043] Furthermore, the first storage housing 11 is provided with a first pair of interfaces, and the inner wall of the first storage housing 11 is in close contact with the pad body on one side of the inflatable air cushion 13. The second storage housing 12 is provided with a second pair of interfaces corresponding to the first pair of interfaces, and the inner wall of the second storage housing 12 is in close contact with the pad body on the opposite side of the inflatable air cushion 13. Magnetic elements are provided on the first pair of interfaces and the second pair of interfaces, and the first storage housing and the second storage housing 12 are connected by the magnetic elements.

[0044] Through the implementation of the amphibious rescue drone described above, utilizing the magnetic attachment, when the amphibious rescue drone needs to be changed to its storage form, rescuers deflate and fold the inflatable air cushion 13, then connect the first storage shell 11 and the second storage shell 12. This allows the first and second storage shells 11 and 12 to quickly connect and fix under the action of the magnetic attachment, allowing the inflatable air cushion 13 to be stored within them. When the amphibious rescue drone needs to be changed to its aquatic form, the inflatable air cushion 13 is simply inflated. The inflatable air cushion 13, through its unfolding force, directly separates the first and second storage shells 11 and 12, thereby achieving rapid storage of the amphibious rescue drone and rapid switching to aquatic mode, improving the efficiency and safety of rescue operations. Preferably, the inflatable air cushion 13 has a structure similar to a lifeboat.

[0045] Furthermore, the first storage housing 11 or the second storage housing 12 is provided with an inflation interface that connects to the inflatable air cushion 13, and the inflation interface is connected to an external air source. An image acquisition device is provided on the first wing 21 or the second wing 22, the image acquisition device is electrically connected to the main control unit, and the main control unit is electrically connected to the control part of the air source.

[0046] Through the implementation of the amphibious rescue drone described above, the air cushion 13 can be inflated via an external air source using the inflation interface on the first storage shell 11 or the second storage shell 12. The air source can be a ground-based air source connected to the amphibious rescue drone via pipeline; alternatively, it can be an air source device mounted on the amphibious rescue drone, eliminating the need for pipeline installation and providing greater scalability to adapt to more complex terrains. Simultaneously, the image acquisition device is preferably a camera, which can capture high-resolution images or videos, providing the drone with the visual information needed for reconnaissance, monitoring, or rescue operations, such as monitoring whether the amphibious rescue drone has contacted the water surface. Once the image acquisition device captures the amphibious rescue drone contacting the water surface, it adaptively controls the amphibious rescue drone to switch to aquatic mode. Furthermore, the electrical connection between the image acquisition device and the main control unit allows the image acquisition device to transmit the acquired images or videos back to the ground terminal in real time, facilitating remote monitoring and decision-making by rescue personnel. Preferably, the amphibious rescue drone in this embodiment also includes a signal light connected to the main control unit, which, according to a preset control circuit, indicates the current mode switched by the amphibious rescue drone.

[0047] Preferably, the first wing 21, the second wing 22, the first storage shell 11, and the second storage shell 12 are all made of high-strength, waterproof, and corrosion-resistant composite materials, such as carbon fiber composites and glass fiber composites, to ensure the reliability of the amphibious rescue drone in both water and air environments. The propeller assembly 23 is made of lightweight, high-strength materials, such as aluminum alloys and carbon fiber, to improve power efficiency and durability. The inflatable air cushion 13 is made of high-strength, waterproof materials, such as rubber or synthetic fibers, to provide good buoyancy and durability.

[0048] This amphibious rescue drone, through three transformation modes, can seamlessly switch between air and water, thereby improving operational efficiency and expanding the application range of amphibious rescue drones. It achieves both air and water navigation using the same wing and propeller assembly 23, reducing equipment complexity and cost, making it lighter and more energy-efficient. Furthermore, combining the drone with an inflatable air cushion 13 aims for rapid rescue, effectively saving rescue manpower and shortening water rescue time.

[0049] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
