Abstract
Description
Technical Field
[0001] This invention relates to the field of aircraft, and more particularly to a multi-rotor flying device suitable for amphibious operations in the air, land, and water. It is applicable to fields that require operations across multiple water, land, and air environments, such as environmental monitoring, emergency rescue, geographical exploration, and material delivery. It can enable a single device to operate continuously in different media environments. Background Technology
[0002] With the rapid development of fields such as emergency rescue, environmental detection, and low-altitude logistics, higher requirements are being placed on the scenario adaptability of operational equipment. Traditional aircraft typically only have a single flight function and cannot achieve stable movement and operation on water or land; while conventional waterborne equipment (such as small speedboats) and land-based equipment (such as small robots) are limited by the medium environment and have difficulty crossing terrain obstacles, thus failing to meet the integrated operational needs of "aerial reconnaissance-water navigation-land movement".
[0003] Among existing amphibious equipment, some amphibious devices can move on water and land, but lack flight capabilities and have insufficient maneuverability in complex terrains (such as high mountains, canyons, and large areas of water). A few devices with flight and land movement capabilities are unable to stay or sail on water because they are not equipped with buoyancy support structures. Moreover, most amphibious equipment suffers from problems such as low redundancy of the power system, complex structure, and high difficulty in operation. In particular, they are prone to poor stability and low operating efficiency when switching between media.
[0004] Furthermore, in emergency rescue scenarios, disaster sites are often accompanied by complex environments with intermingling water and land and fragmented terrain. Traditional single-function equipment requires multiple units to work together, which not only increases the cost of equipment deployment and operational complexity, but may also cause delays in coordination between equipment, resulting in missed rescue opportunities. In the field of environmental monitoring, a single device cannot continuously complete multiple tasks such as large-scale aerial mapping, water surface sampling, and land sample collection, leading to extended monitoring cycles and insufficient data continuity.
[0005] Therefore, there is an urgent need to develop new types of amphibious multi-rotor flying devices suitable for land, sea, and air, in order to solve the problems of poor adaptability to multiple scenarios, single function, and insufficient cross-media operation capability of existing equipment. Summary of the Invention

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0021] Example 1:
[0022] like Figure 1 This embodiment is applicable to a amphibious multi-rotor flight device, including an upper support 13, an airbag 14, a control board 15, a control board support 16, an antenna 17, a camera 18, and a lower support 19.

Preferably, a first motor 1, a second motor 2, a third motor 3, a fourth motor 4, a fifth motor 5, and a sixth motor 6 are mounted on the surface of the upper support 13. A first blade 7 is mounted on the surface of the first motor 1, a second blade 8 is mounted on the surface of the second motor 2, a third blade 9 is mounted on the surface of the third motor 3, a fourth blade 10 is mounted on the surface of the fourth motor 4, a fifth blade 11 is mounted on the surface of the fifth motor 5, and a sixth blade 12 is mounted on the surface of the sixth motor 6.
[0024] In a further embodiment, a seventh motor 21 is installed at the front right side of the lower bracket 19, and a first spiral roller 20 is installed on the right side of the lower bracket 19, with the first spiral roller 20 connected to the seventh motor 21. An eighth motor 22 is installed at the front left side of the lower bracket 19, and a second spiral roller 23 is installed on the left side of the lower bracket 19, with the second spiral roller 23 connected to the eighth motor 22.
[0025] Example 2:
[0026] like Figure 1 and Figure 2 This embodiment is applicable to a amphibious multi-rotor flight device, and also includes a ninth motor 24 mounted on the left rear end of the lower support 19, with a first propeller 25 mounted on the output shaft of the ninth motor 24. A tenth motor 26 is mounted on the rear end of the lower support 19, with a second propeller 27 mounted on the output shaft of the tenth motor 26.
[0027] Working principle of the invention:
[0028] This invention centers on "modular power matching + cross-media scenario adaptation," using airbags to provide basic support and combining the coordinated control of multiple motors and actuators to achieve stable operation and scenario switching in amphibious environments. The specific working principle is explained in three main scenarios:
[0029] I. Working Principle of In-flight Scenarios
[0030] The flight function is achieved through the coordinated operation of six motor-blade assemblies (first motor 1 to sixth motor 6, corresponding to first blade 7 to sixth blade 12) on the upper support and the control board 15. After receiving remote control signals via antenna 17, the control board 15 outputs independent control commands to the six motors according to flight requirements (such as takeoff, hovering, turning, and landing).
[0031] During takeoff, six sets of motors synchronously drive the blades to rotate at high speed, generating upward lift to overcome the overall weight of the device and achieve vertical takeoff and landing.
[0032] When hovering, the control panel monitors the flight attitude (such as horizontality and altitude) in real time and maintains the device's stable position in the air by fine-tuning the speed of different motors (such as adjusting the speed of the diagonal motors to balance the lateral offset).
[0033] When turning or translating, the speed of the motor on one side is controlled differently (e.g., the speed of the left motor is higher than that of the right motor, generating lateral torque), and the drive device turns or moves in the horizontal direction.
[0034] During landing, the control panel gradually reduces the speed of the six motors, so that the lift is slowly less than the gravity, achieving a smooth landing. Throughout the process, camera 18 can be activated simultaneously to complete aerial reconnaissance, mapping and other operations.
[0035] Meanwhile, the redundant design of the six motors can improve flight reliability—if a single motor fails, the control board will immediately identify it and compensate for the power loss of the failed motor by increasing the speed difference of the other five motors, thus preventing the device from becoming unstable.
[0036] II. Working Principle of Land Mobile Scenarios
[0037] The land mobility function relies on two sets of spiral roller-motor assemblies (seventh motor 21 - first spiral roller 20, eighth motor 22 - second spiral roller 23) on the support frame. The core is to adapt to complex land terrain through the special structure of the spiral rollers.
[0038] After receiving the land movement command, the control board 15 outputs speed and direction signals to the seventh motor 21 and the eighth motor 22.
[0039] When moving in a straight line, the two sets of motors rotate synchronously in the forward or reverse direction, driving the spiral roller to rotate. The spiral teeth contact the ground to generate forward or backward propulsion force. The spiral structure can adapt to uneven road surfaces such as gravel, grass, and shallow pits (power transmission can still be maintained when the spiral teeth are embedded in loose ground to avoid slippage).
[0040] When turning, by controlling the speed difference between the two sets of motors (e.g., the speed of the seventh motor is higher than that of the eighth motor), the spiral rollers on both sides generate different propulsion speeds, forming a steering torque, thus enabling the device to turn flexibly on land.
[0041] During the operation, the camera 18 can work in conjunction with the movement trajectory to complete tasks such as land sample observation and target positioning. The control board records the movement path and operation data in real time and transmits them back to the remote terminal through the antenna 17.
[0042] III. Working Principle of Surface Navigation Scenarios
[0043] The operation in the water surface scenario relies on the buoyancy support of the airbag and the coordinated action of the two propeller-motor assemblies (ninth motor 24 - first propeller 25, tenth motor 26 - second propeller 27) on the lower support:
[0044] When the device enters the water, the airbag 14 directly supports the entire device to float on the water due to its own buoyancy, preventing water from entering the lower support and motor assembly.
[0045] After receiving the navigation command on the water surface, the control board 15 starts the ninth motor 24 and the tenth motor 26 to drive the first propeller 25 and the second propeller 27 to rotate, generating a backward thrust to propel the device to sail at a constant speed on the water surface.
[0046] When turning, the speed of the two propellers is adjusted (e.g., the speed of the ninth motor is reduced while the speed of the tenth motor remains unchanged) to make the thrust on both sides of the device different, thereby creating a turning torque and achieving turning on the water surface.
[0047] If it is necessary to stay on the water surface for operation (such as water quality sampling to assist positioning), the control board can turn off the propeller motor and maintain the floating state only through the airbag. The camera 18 will collect water surface environmental data simultaneously to complete the monitoring task.
[0048] IV. Working Principle of Cross-Scene Switching
[0049] The switching between amphibious scenarios requires no disassembly or assembly of components; the control board 15 automatically completes the switching and coordination of the power system.
[0050] When switching from "air to water / land", the control board first reduces the speed of the upper support flight motor, so that the device slowly approaches the target medium; after contacting the water surface, the flight motor is immediately turned off and the propeller motor is started; after contacting the land, the flight motor is turned off and the propeller roller motor is started, realizing "switching from air landing to water landing".
[0051] When switching from "land / water surface → air", the control panel first shuts down the land / water surface power motors and simultaneously starts the six flight motors on the upper support. Once sufficient lift is generated, the device detaches from the land / water surface and enters flight mode. The entire switching process requires no manual intervention, has a short response time, and is suitable for the needs of emergency rescue and other scenarios requiring rapid scene transitions.
[0052] Compared to traditional mono-amphibious (only air-flying, only land-moving, or only water-navigating) or amphibious equipment, this invention, through an integrated structure of "multi-rotor propulsion on the upper support + land / water-based drive on the lower support + airbag buoyancy support," achieves tri-amphibious operational capabilities for the first time. It can complete a continuous mission of "aerial reconnaissance and positioning - rapid water-based approach - precise land-based operations" in emergency rescue, and can also simultaneously perform aerial mapping, water quality sampling, and land-based sample collection in environmental monitoring. This solves the problems of existing equipment requiring multiple units to coordinate and having low efficiency in scene switching, significantly improving operational continuity and coverage.
[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
