Description

Technical Field

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

[0002] With the rapid development of drone technology, it has been widely applied in various industries, especially in transportation, search and rescue, detection, and exploration. Traditional drones can only fly in the sky, which has significant limitations in practical applications. As waterways are further developed, the frequency of maritime activities is increasing, leading to more water patrols, inspections, explorations, and rescues, resulting in a surge of various maritime accidents. In response to these challenges, amphibious drones have begun to be researched and developed, and are gradually being applied in various industries.

[0003] Amphibious drones are a type of drone with unique capabilities, capable of operating in both air and water environments. Patent No. 201610656822.4, titled "Amphibious Drone," lacks a separate motor and propellers for water operation. Instead, it adjusts its tilt relative to the water surface by changing the size of its airbags. The drone is propelled along the water surface by a combination of an airborne propeller and a rotary rotor. However, this method results in relatively slow speeds and less agile movement on the water. Patent No. 202322477932.2, titled "Waterborne Information Collection Flying Buoy," allows a drone carrying a detector to fly to any body of water. The drone lands and floats on the water, using the detector to assess water quality. However, lacking a separate propulsion motor for water navigation, it cannot freely navigate on the surface. Patent No. 202120515349.4, entitled "A Frame Structure and Control System for Amphibious Unmanned Aerial Vehicles," has an independent underwater motor. However, the two motors are too close together, and the design of the device for suspending the vehicle on the water surface is unreasonable, resulting in insensitive steering on the water surface.

[0004] Currently, some amphibious drones use their airborne motors and propellers in the water, ignoring the differences between airborne and waterborne motors and propellers, resulting in low surface speeds. Other amphibious drones, while possessing independent motors and propellers for surface navigation, suffer from excessive redundancy and poor structural design, failing to adequately balance airborne and surface navigation. Particularly in surface navigation, some amphibious drones have poorly designed buoyancy devices, resulting in insufficient buoyancy and lack of agility. These shortcomings significantly hinder their use in real-world environments. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides the following technical solution: an amphibious aircraft, comprising an air motor, a middle compartment, a connecting rod, and surface floats. One end of the connecting rod is connected to the side of the front floats, and the other end passes through the middle compartment and connects to the battery compartment. The middle compartment includes a middle compartment cover, a waterproof camera, a battery compartment, a battery compartment cover, a flight controller, a receiver, an RTK module, an air motor ESC, an aluminum alloy heat sink, and an underwater motor ESC. The middle compartment cover is installed on the upper part of the middle compartment, and an RTK antenna is installed on the upper surface of the middle compartment cover. A waterproof camera is installed at the front end of the exterior of the middle compartment. The flight controller and RTK module are installed on the upper surface of the battery compartment. The receiver is installed at the front end inside the middle compartment. The battery compartment is installed in the middle-rear part inside the middle compartment, and the battery compartment cover is installed at the rear of the middle compartment. The air-mounted motor ESC and the underwater motor ESC are installed on the bottom surface inside the intermediate compartment, and the aluminum alloy heat sink is installed on the bottom surface outside the intermediate compartment. The surface buoy includes a front buoy, a front-middle buoy, a middle-rear buoy, a rear buoy, and an underwater motor housing. The air-mounted motor is installed on the upper surface of the front buoy and its upper side is connected to a connecting rod. The lower side of the front buoy is connected to the front-middle buoy. One end of the front-middle buoy is connected to the middle-rear buoy and the other end is connected to the lower side of the front buoy. One end of the middle-rear buoy is connected to the front-middle buoy and the other end is connected to the rear buoy. The air-mounted motor is installed on the upper surface of the rear buoy and its upper side is connected to a connecting rod. The lower side of the rear buoy is connected to the middle-rear buoy. The underwater motor housing is installed on the sides of the front-middle buoy and the middle-rear buoy, and the underwater motor is installed inside the underwater motor housing.

[0006] Preferably, the four parts of the surface pontoon—the front pontoon, the front-middle pontoon, the middle-rear pontoon, and the rear pontoon—are hollow and independent enclosed areas, and their interiors are not interconnected.

[0007] Preferably, the four corners of the battery compartment are connected to four connecting rods, forming a rigid connection between the four connecting rods and the battery compartment. The outlet of the battery compartment corresponds perfectly with the rear outlet of the middle compartment, facilitating quick battery replacement.

[0008] Preferably, the bottom surface of the intermediate compartment is equipped with many internal supports to support the internal components; even if the bottom surface of the intermediate compartment is relatively thin, it also increases the strength of the bottom surface of the intermediate compartment.

[0009] Preferably, the heat dissipation surfaces of the underwater motor ESC and the air motor ESC are in close contact with the upper surface of the aluminum alloy heat sink with zero gap.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] It has a separate underwater motor, and there is a certain distance between the two motors, which enables the amphibious aircraft to navigate quickly and nimbly on the water surface; the underwater motor and the surface float adopt an integrated design, reducing redundant components and optimizing the structural layout.

[0012] The floats on both sides provide buoyancy. The floats are designed in sections to prevent accidents caused by leakage from a small part of the float.

[0013] The intermediate compartment has a rational internal structure design, which improves space utilization. The bottom of the intermediate compartment has many internal supports, which not only support the internal components, but also increase the strength of the intermediate compartment's bottom.

[0014] The battery is housed in a separate battery compartment for easy battery replacement via express delivery. The battery compartment is connected to four connecting rods to form a whole, with the rigid center of this whole located inside the battery compartment. At the same time, because the battery is relatively heavy, it can reduce vibration or shaking during flight, making the flight more stable. Attached Figure Description

[0027] like Figures 1-9As shown in the figure, this utility model embodiment proposes an amphibious aircraft, including an air motor 1, a middle compartment 3, a connecting rod 4, and a surface float 5. One end of the connecting rod 4 is connected to the side of the front float 501, and the other end passes through the middle compartment 3 and connects to the battery compartment 302. The middle compartment 3 includes a middle compartment cover 2, a waterproof camera 301, a battery compartment 302, a battery compartment cover 303, a flight controller 304, a receiver 305, an RTK module, an air motor ESC 306, an aluminum alloy heat sink 307, and an underwater motor ESC 308. The intermediate compartment cover 2 is installed on the upper part of the intermediate compartment 3. An RTK antenna 201 is mounted on the upper surface of the intermediate compartment cover 2. A waterproof camera 301 is installed at the front end of the exterior of the intermediate compartment 3. The flight controller 304 and the RTK module are installed on the upper surface of the battery compartment 302. The receiver 305 is installed at the front end inside the intermediate compartment 3. The battery compartment 302 is installed in the middle-rear part inside the intermediate compartment 3. The battery compartment cover 303 is installed at the rear of the intermediate compartment 3. The air motor ESC 306 and the underwater motor ESC... 308 is installed on the bottom surface inside the intermediate compartment 3, and the aluminum alloy heat dissipation plate 307 is installed on the bottom surface outside the intermediate compartment 3; the surface float 5 includes a front float 501, a front middle float 502, a middle and rear float 503, a rear float 504, and an underwater motor housing 505. The upper surface of the front float 501 is equipped with an aerial motor 1, and its upper side is connected to the connecting rod 4. The lower side of the front float 501 is connected to the front middle float 502, and one end of the front middle float 502 is connected to the middle and rear float 503. The other end is connected to the lower side of the front float 501. One end of the middle and rear float 503 is connected to the front middle float 502 and the other end is connected to the rear float 504. The upper surface of the rear float 504 is equipped with the aerial motor 1 and the upper side is connected to the connecting rod 4. The lower side of the rear float 504 is connected to the middle and rear float 503. The underwater motor housing 505 is installed on the side of the front middle float 502 and the middle and rear float 503. The underwater motor 506 is installed inside the underwater motor housing 505.

[0028] like Figures 6-8As shown, the interior of the intermediate compartment 3 mainly houses control components and batteries. To save space, the interior is divided into different areas. The front of the intermediate compartment 3 houses the receiver 305 and some power or signal cables. The rear middle section houses the battery compartment 302, whose outlet corresponds perfectly to the rear outlet of the intermediate compartment 3, facilitating quick battery replacement. The space between the battery compartment 302 and the battery compartment cover 2 can accommodate components such as the flight controller 304 and the RTK module. The bottom of the intermediate compartment 3 houses the underwater motor ESC 308 and the airborne motor ESC 306. Their heat dissipation surfaces are tightly attached to the upper surface of the aluminum alloy heat sink 307, facilitating heat dissipation during flight or navigation. Simultaneously, the bottom of the intermediate compartment 3 has numerous internal supports 309 to support the internal components; even with a relatively thin bottom surface, this increases the strength of the intermediate compartment 3. The four corners of the battery compartment 302 are connected to four connecting rods 4. This connection method makes the four connecting rods 4 and the battery compartment 302 form a rigid connection body, with the rigid center of this whole body located inside the battery compartment 302. Since batteries are generally relatively heavy, this reduces vibration or shaking during flight, making flight more stable. In addition, the high positioning accuracy of the RTK module also contributes to stable flight.

[0029] The surface navigation system primarily relies on the surface buoy 5 and the underwater motor 506. The underwater motor 506 is located in the middle of the inner side of the surface buoy 5. The underwater motor 506 and the surface buoy 5 are integrated into a single design, reducing redundant components and making surface navigation more agile and swift. Figure 9 As shown, the four parts of the surface float 5—the front float 501, the front-middle float 502, the middle-rear float 503, and the rear float 504—are hollow and independent enclosed areas, and their interiors are not interconnected. During surface navigation, even if one part of the surface float 5 is damaged and water enters, the amphibious aircraft will not sink.

[0030] When the amphibious aircraft receives an inspection order, the air-mounted motor 1 rotates, driving the propeller on its motor to propel the aircraft into flight. Upon reaching the designated water area, the amphibious aircraft lands on the water surface, where the surface floats 5 provide buoyancy. The air-mounted motor 1 stops rotating, and the underwater motor 506 begins rotating according to instructions. Because the underwater motor 506 and the surface floats 5 are integrated, surface navigation is more agile and effective. After completing surface inspection and other tasks, the aircraft can return to the shore of the designated water area by surface navigation; alternatively, it can take off directly from the water and fly to the designated area.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
