Description

Technical Field

[0001] The present invention relates to the field of aviation technology, and in particular to a land-air cruiser. Background Art

[0002] With the continuous advancement of aircraft technology, aircraft are increasingly used in reconnaissance, logistics, monitoring, search and rescue and other fields. However, traditional aircraft still face many challenges in terms of portability, rapid deployment and multi-environment adaptability. The structure of existing aircraft is usually composed of core components such as fuselage, wings, tail, landing gear and power system, forming a complex air transportation platform. Since most aircraft require a long runway for takeoff and landing, and usually require a special hangar to protect them from bad weather and environmental factors during maintenance and storage, in addition, the safety of flight operations requires a large space buffer. The special space requirements of large aircraft during transportation and operation have further aggravated the limitations of space and deployment time. The combined effect of these factors has led to the fact that traditional aircraft require a lot of space in practical applications and have a long deployment time, which seriously restricts their application in emergency response and missions with strong mobility.

[0003] Although some aircrafts on the market are portable to a certain extent, the separation of their supporting transportation tools from the aircraft's own functions makes the deployment process of the aircraft still cumbersome. Usually, the deployment process of the aircraft includes accurately assembling various hardware components such as the frame, propeller, motor, ESC, flight control board, etc. according to the technical documents; then completing the connection between the motor and the ESC to ensure the correct direction of motor rotation; then installing the flight control board and other accessories such as memory card and buzzer, and performing necessary wiring work to connect the ESC, receiver and feedback module; finally installing the battery and performing system testing to check the direction of motor rotation, flight control system response and signal receiver sensitivity. According to the test results, adjust the PID control parameters, the matching relationship between the motor KV value and the propeller, and the ESC settings. The whole process requires not only precise technical operations, but also sufficient space for safety testing and adjustment to ensure the performance and safety of the aircraft. This makes the deployment process cumbersome and time-consuming, especially in mission scenarios that require rapid response, where traditional separate transportation and functional configuration seriously reduce efficiency. In addition, existing aircraft systems often rely on complex launch or take-off devices, which further increases their use cost and operation difficulty.

[0004] Therefore, there is an urgent need for an integrated solution that can effectively combine the functions of aircraft and transportation tools to achieve more efficient transportation, deployment and flight operations, especially in application scenarios with frequent movement and rapid response. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned defects of the prior art, thereby providing a land-air cruiser.

[0007] An aircraft transport vehicle, the transport vehicle comprising a trailer body, a trailer hook, wheels, doors and at least one mounting interface; and

[0008] An aircraft, the aircraft comprising an aircraft body, a landing gear, a propeller mechanism and a power system; wherein,

[0013] As an improvement of the above system, the propeller body includes an electrically controlled magnetic locking system and a plurality of rotors; wherein the locking system is used to control the folding and unfolding of the plurality of rotors; wherein the plurality of rotors overlap with each other in a folded state, and the plurality of rotors are evenly arranged along the circumference in an unfolded state.

[0015] As an improvement of the above system, the aircraft body includes a manned space, and at least one manned seat is arranged in the manned space.

[0016] As an improvement to the above system, the power system of the aircraft adopts a gasoline-electric range-extended power system, which combines electric drive and an internal combustion engine.

In addition, the adjustable mounting interface and openable door design of the aircraft transportation tool make the loading and unloading of the aircraft more efficient and safe, and optimize space utilization. In particular, the aircraft adopts a foldable design, which can significantly save space and enhance portability during transportation and storage. The folded volume is greatly reduced, which is convenient for transportation, storage and rapid deployment. This design not only improves the space utilization of the system, but also enhances its adaptability, and can meet the needs of rapid response in a changing environment.

[0028] The technical solution provided by the present invention is further illustrated below in conjunction with embodiments.

[0029] like Figure 1 As shown, this embodiment provides a land-air cruiser, including an aircraft transportation vehicle and an aircraft.

[0030] Aircraft transport tools are used to provide an efficient and safe transportation platform for aircraft, while creating convenient conditions for the storage, maintenance and deployment of aircraft. At the same time, aircraft transport tools adopt a modular design, and the whole can be selectively used according to mission requirements. This design allows users to use different methods according to different usage environments.

[0031] like Figure 1 As shown, the aircraft transport vehicle includes: a trailer body 11, a trailer hook 12, wheels 13, a first trailer door 14 and a second trailer door 15. The trailer hook 2 is connected to the head end of the trailer body 1 by welding, the wheels 3 are fixed to the trailer body 1 by high-strength bolts, and the tail end of the trailer body 1 is connected to the first trailer door 14 and the second trailer door 15 by a hinged manner. The design of the transport vehicle has high operability, flexibility and scalability, and is suitable for efficient transportation, rapid deployment and multi-functional cargo application of aircraft. The structure of each component of the aircraft transport vehicle provided in this embodiment is as follows:

[0032] Trailer hook 12: The trailer hook 12 adopts a U-shaped structure and is made of cast iron, which has excellent tensile strength and durability. The trailer hook 12 is firmly connected to the outside of the head end of the trailer body 11 through a welding process to form a reliable towing connection point. The U-shaped structural design makes the connection between the trailer hook 12 and the towing vehicle more stable, ensuring uniform distribution of the load during transportation and reducing the risk of uneven towing load.

[0033] Wheel 13: Wheel 13 is round in design and is made of aluminum alloy and rubber. Aluminum alloy is lightweight and corrosion-resistant, while rubber provides excellent shock absorption and adaptability to different road conditions. Wheel 13 is connected to trailer body 11 by high-strength bolts, ensuring a solid connection between wheel 13 and trailer body 11, supporting stable driving under high load or uneven terrain.

[0034] Trailer body 11: The trailer body 11 has a square profile, and the overall structure is made of steel plates and cast iron materials. The steel plates provide the trailer body 11 with excellent compression resistance, while the cast iron enhances the trailer body 11's resistance to bending and impact. The trailer body 11 is connected to the first trailer door 14 and the second trailer door 15 via a hinged structure, so that the first trailer door 14 and the second trailer door 15 can be opened and closed freely, thereby facilitating the loading and unloading of aircraft or materials. At the same time, the hinged connection between the trailer body 11 and the first trailer door 14 and the second trailer door 15 ensures smooth operation and durability in long-term use. Figure 3 As shown, one or more expandable mounting interfaces 16 are designed at the bottom of the inner side or / and around the inner side of the trailer body 11. Users can dock and lock the corresponding fixed interface on the aircraft with the mounting interface 16 of the trailer body 11 according to their needs, so as to ensure that the aircraft is stably fixed during transportation and avoid potential damage to the aircraft due to bumps and vibrations on the road. These adjustable mounting interfaces 16 have strong carrying capacity and adaptability, which can effectively reduce the impact of unstable factors on the road on the aircraft and ensure the safety and stability of the aircraft during transportation. In addition, when the aircraft transportation vehicle is not used to transport the aircraft, these mounting interfaces 16 can also be flexibly used to mount other required items or equipment. Through simple interface adjustment, users can easily configure different loading modes according to actual needs, further improving the versatility and applicability of the trailer. This design not only enhances the transportation efficiency of the trailer, but also provides higher space utilization, meeting the flexible switching of different transportation needs.

[0035] Door design: The first trailer door 14 and the second trailer door 15 are made of aluminum alloy, which not only ensures the strength of the door but also reduces the dead weight. The first trailer door 14 and the second trailer door 15 are arranged at the rear end of the trailer body 11 opposite to the front end of the trailer body 11. The first trailer door 14 and the second trailer door 15 can be arranged sideways opposite to each other. Figure 2 The first trailer door 14 and the second trailer door 15 are shown in a schematic diagram after being opened and arranged sideways. The first trailer door 14 and the second trailer door 15 can also be arranged up and down. Figure 3The schematic diagram of the first door 14 and the second door 15 of the trailer being opened relative to each other is shown. In other embodiments, one or more doors or other forms of doors may be provided, as long as the doors are opened, the opening passage is sufficient for the aircraft to enter and exit. The doors are connected by high-precision hinges to ensure the smoothness of the switch operation. When transporting aircraft or other materials, the opening angle and design of the doors make the loading and unloading operations more efficient and can effectively protect the transported items from the external environment. The rear end of the trailer body 11 is provided with doors to form an openable structure, which provides users with higher flexibility and allows users to choose the most suitable loading and take-off method according to different application requirements. The design of the openable rear end is particularly taken into account of the direct take-off and landing requirements of the aircraft, which can significantly simplify the operation process and improve the efficiency of use. For example, when the aircraft is ready to take off, the traditional method usually requires manual or other auxiliary systems to remove the aircraft from the trailer body 11, and it can take off only after a series of deployments. With this design, the driver can directly enter the interior of the aircraft, open the rear end of the trailer body 11, and the aircraft can be smoothly driven out and immediately put into take-off operation. This design avoids unnecessary steps in the traditional deployment process, saves time for manual handling and equipment deployment, and greatly improves the efficiency of takeoff preparation. At the same time, this design not only significantly reduces the preparation time before the aircraft takes off, but also reduces dependence on manpower, reduces operational complexity and potential safety risks, thereby optimizing the use cost and operating efficiency of the aircraft. Through this innovative improvement, the aircraft can complete deployment and takeoff in a shorter time, which is especially suitable for mission scenarios that require rapid response and high-frequency operations.

[0036] Dual-mode transportation and storage design This aircraft transport tool can flexibly switch between different transportation modes as needed. When transporting an aircraft, the trailer body 11 is connected to the towing vehicle through the trailer hook 12 at the front end, and the aircraft is safely stored in the trailer to ensure the stability and safety of the aircraft during transportation. In addition, the trailer design also supports its conversion into a standard cargo mode for transporting other equipment or materials. Through modular design, the trailer can not only effectively accommodate the aircraft, but also maximize the use of space and provide greater storage capacity by adjusting the internal storage layout.

[0037] This solution saves users the time and cost of preparing a second vehicle by integrating aircraft storage and transportation. Without the need to prepare a separate vehicle for transporting aircraft, the time and cost of vehicle preparation, loading and dispatching are reduced, and work efficiency is improved. Secondly, the multifunctional design of the trailer enables it to flexibly adapt to the transportation needs of a variety of other equipment and materials while transporting aircraft, greatly improving the adaptability and expansion capacity of the trailer. Finally, the innovative door structure and high-strength connection design make the loading and unloading of aircraft or materials more convenient, and the operation easier and safer. The design of this aircraft transport tool has high adaptability, flexibility and efficiency, and can be widely used in the transportation and rapid deployment of aircraft, equipment and materials, especially in emergency response, rapid deployment and multi-task scenarios, with excellent application value. This technical solution not only improves transportation efficiency and reduces costs, but also enhances the versatility and market competitiveness of transportation tools, and has great commercial potential.

[0038] like Figure 4 As shown, the aircraft provided in this embodiment includes: an aircraft body 23, a landing gear 24 and two identical propeller mechanisms. The aircraft body 23 is connected to the landing gear 24 and the two identical propeller mechanisms.

[0039] The propeller mechanism includes: a propeller 21, a motor 22, a first paddle arm 25, and a second paddle arm 26. The first end of the first paddle arm 25 is connected to the aircraft body 23 through a hinged and locked structure, and the second end of the first paddle arm 25 is connected to the first end of the first paddle arm 25 through a hinged and locked structure. The second section of the first paddle arm 25 is equipped with a motor 22 and a propeller 21. The motor 22 and the propeller 21 are connected through a bearing and a coupling to achieve power transmission. The locking structure can be self-locking using a button and a spring. This connection method can ensure that the first paddle arm 25 and the second paddle arm 26 can be fixed and kept stable after being deployed or folded, and can also ensure that the angle and position after being deployed or folded are not deformed. While ensuring convenience, this design also takes into special consideration the stability and durability of the structure. The paddle arm adopts a modular design, and the two paddle arms are self-locking through a button and a spring mechanism to ensure that the paddle arm will not be deformed due to external force or operational errors after being deployed. The connection between the propeller arm and the aircraft body is locked by a positioning piece to ensure that the angle of the propeller arm is fixed after it is deployed, thereby preventing accidental folding or displacement during flight.

[0040] The propeller 21 includes a plurality of rotors and an electrically controlled magnetic locking system. The electrically controlled magnetic locking system controls the folding or unfolding of the plurality of rotors. In the unfolded state, the plurality of rotors are evenly arranged around the circumference. In the folded state, the plurality of rotors overlap each other. The rotors are folded using an electrically controlled magnetic locking system. The user only needs to perform simple operations to complete the locking or unlocking action. The folding or unfolding process can be completed within a few seconds, which greatly simplifies the operation process and improves the user experience. The electronic control system combines sophisticated mechanical structures and materials to ensure that the rotors maintain high stability and reliability during the folding and unfolding process, and are not affected by the external environment and the frequency of use.

[0041] The landing gear 24 is connected to the aircraft body 23 through a strong hinge device, providing stable support and playing a cushioning role when the aircraft lands. The aircraft door 27 is connected to the aircraft body 23 through a hinge to ensure that the door can be opened and closed smoothly and firmly, facilitating entry and operation of the aircraft. These components jointly ensure the structural stability, functional reliability and flight performance of the aircraft through strict mechanical connections.

[0042] The aircraft adopts a new folding structure design, which can significantly save space and enhance portability during transportation and storage. Specifically, the landing gear 24, propeller arms and rotors of the aircraft can be quickly folded into a very small volume through an innovative folding mechanism. Figure 5 A schematic diagram of the aircraft after folding is shown. After folding, its volume is about one-third of that in the unfolded state, which greatly improves the space utilization efficiency of the aircraft. This design not only makes it easy for users to carry the aircraft into the trailer, but also optimizes the space of the trailer, allowing more items or equipment to be stored and transported with the aircraft. The aircraft achieves efficient, reliable and easy-to-operate functions during the folding and unfolding process, adapting to the needs of different environments, especially in application scenarios that require rapid deployment and frequent movement, and can provide excellent convenience and transportation efficiency. The folding structure and modular design of the aircraft not only optimizes storage and transportation, but also significantly reduces the complexity of operation, enhancing the applicability and market competitiveness of the aircraft.

[0043] In order to further optimize the aircraft, a coupling structure 27 is designed at the bottom of the aircraft, and the coupling structure 27 can be coupled with the mounting interface 16 of the trailer body 11. For example, the mounting interface 16 of the trailer body 11 can be a raised positioning column or a locking protrusion, and the coupling structure 27 of the aircraft can be a recessed area or a positioning groove. This design achieves a stable fixation of the aircraft and the aircraft transportation vehicle through simple and efficient mechanical coordination, avoiding damage or displacement of the aircraft due to vibration or bumps during transportation. Through the coupling structure 27, the aircraft can remain stable in the trailer body 11, and will not loosen or deflect during movement, thereby ensuring the safety of the aircraft in long-distance transportation or complex terrain. In addition, when the aircraft is fixed in the trailer body 11, the design also ensures the rapid deployment capability of the aircraft. After arriving at the destination, the user only needs to simply operate to release the fixation and quickly complete the take-off preparation of the aircraft. This fixed structure not only reduces the complexity of deployment, but also improves transportation efficiency, significantly shortens the use preparation time of the aircraft, and is particularly suitable for application scenarios that require rapid response and frequent movement. This design enhances the compatibility and stability of the aircraft and the aircraft transport vehicle, and improves the safety and convenience of the overall transportation and operation process.

[0044] Furthermore, if Figure 7 and Figure 8 As shown, the aircraft is also provided with a manned space 28 and an aircraft door 29, and at least one manned seat 30 is provided in the manned space. The design fully considers the manned function of the aircraft, enabling it to carry personnel for transportation when performing specific tasks, greatly expanding the application scenarios of the aircraft. Unlike most existing civil aircraft, this aircraft is specially integrated with a manned system and provides a dedicated manned space, thereby meeting the needs for personnel transportation in emergency rescue, aerial monitoring, patrol and other tasks.

[0045] Furthermore, the aircraft adopts a petrol-electric extended-range power system, which combines electric drive with an internal combustion engine to provide excellent endurance and flexible power configuration. The system optimizes the overall performance of the aircraft by intelligently switching between electric and fuel power. The electric system is mainly used for short-term takeoff, cruising and fine control of the aircraft, with the advantages of low noise, environmental protection and high efficiency, while the internal combustion engine provides additional power support during long-term flight and long-range missions, significantly extending the endurance of the aircraft. The petrol-electric extended-range design not only greatly improves the endurance of the aircraft, but also enables it to perform long-term, high-intensity tasks away from charging facilities or power sources. This design is particularly suitable for tasks that require operations in remote areas, complex environments or for long periods of time, such as long-term monitoring, rescue operations and air patrols. Whether switching to the internal combustion engine when the battery is exhausted or adjusting the power according to mission requirements, the system can ensure the continuous operation of the aircraft, maximize work efficiency and reduce flight interruptions. Through the integration of the oil-electric extended-range power system, this aircraft can maintain stability and efficiency when performing long-term missions, meet various operational requirements in complex environments, greatly improve the adaptability, reliability and application scope of the aircraft, and provide users with a more efficient flight experience and broader application prospects.

[0046] From the above detailed description of the present invention, it can be seen that the biggest highlight of the present invention is the integration of the aircraft transportation tool and the aircraft to form a highly portable and powerful mobile platform. The specific advantages are as follows:

[0047] 1. Rapid deployment and efficient operation

[0048] Traditional aircraft usually require multiple steps during transportation and deployment, and the operation is cumbersome. However, the present invention greatly simplifies the operation process through the innovative combination of modular aircraft transportation tools and foldable aircraft. The entire system can be deployed, take off and perform tasks within a few minutes, significantly shortening the response time. This efficient operation method is particularly suitable for emergency missions and high-frequency operation scenarios, and can provide rapid response at critical moments.

[0049] 2. Self-powered and environmentally friendly advantages

[0050] The aircraft of the present invention is equipped with a hybrid power system of oil-electric range extension, which can provide the aircraft with self-powered function, and is particularly suitable for long-term outdoor missions. When the external power supply is unavailable, the aircraft transportation vehicle can use the built-in energy system to provide sufficient power support for the aircraft, ensuring that the aircraft is not restricted by insufficient power during the mission execution. In addition, the oil-electric range extension system not only improves the endurance, but also effectively reduces the dependence on traditional fossil fuels, conforms to modern environmental protection concepts, and improves the sustainability of the system.

[0051] 3. Rapid takeoff and landing

[0052] After the openable structure designed at the rear of the trailer body 11 of the aircraft transport vehicle is opened, the aircraft can take off or land directly through the open space. Unlike the traditional aircraft that needs to be manually moved out and then take off, the design of the present invention allows the aircraft to be quickly deployed and recovered without additional handling, greatly improving the convenience and efficiency of operation. This innovation is particularly suitable for use in mission scenarios that require rapid response, such as emergency rescue and disaster response, and can effectively shorten deployment time and improve mission execution efficiency.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention is described in detail with reference to the embodiments, it should be understood by those skilled in the art that any modification or equivalent replacement of the technical solutions of the present invention does not depart from the spirit and scope of the technical solutions of the present invention and should be included in the scope of the claims of the present invention.
