Description

Technical Field

[0001] The present invention relates to the technical field of aircraft, and in particular to a modular aircraft. Background Art

[0002] A modular aircraft utilizes a modular design concept, dividing its various functional components into relatively independent, standardized modular units, such as propulsion modules, control modules, payload modules, and energy modules. These modules are interchangeable and independent, allowing for flexible combination, rapid replacement, or upgrades based on mission requirements. Modular aircraft enhance design and manufacturing flexibility, shorten R&D cycles, reduce maintenance and modification costs, and adapt to diverse application scenarios, such as reconnaissance, transportation, and communications.

[0003] Currently, aircraft are widely used in a variety of fields, including air transportation, aerial reconnaissance, emergency rescue, and scientific exploration. Traditional aircraft often utilize an integrated structural design with fixed functional configurations and a high degree of integration. While these designs offer a certain degree of stability, they face significant limitations in adapting to diverse mission requirements, reducing maintenance costs, and improving module replacement efficiency. In particular, if a component fails during a mission, the entire aircraft must be repaired or replaced, resulting in a waste of resources and making rapid deployment difficult. Consequently, these aircraft present certain limitations during use.

[0004] To this end, developing a modular aircraft structure that can quickly disassemble and assemble functional components and improve system flexibility, scalability, and adaptability has become a research hotspot in the field of aircraft design. Based on this, we propose a modular aircraft. Summary of the Invention

[0005] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the present invention to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0006] Therefore, the purpose of the present invention is to provide a modular aircraft that can solve the problems of traditional aircraft having fixed functional configuration and high integration due to their integrated structure, and having great limitations in adapting to diversified mission requirements, reducing maintenance costs, improving module replacement efficiency and rapid deployment.

[0007] In order to solve the above technical problems, the present invention provides a modular aircraft, which adopts the following technical solution: it includes a control fuselage, a support assembly is installed at the bottom of the control fuselage, and propulsion assemblies are distributed around the outer side of the control fuselage. The propulsion assembly includes two groups of first propellers, and the two groups of first propellers are respectively connected to the two ends of the control fuselage, and two groups of second propellers are respectively provided on both sides of the control fuselage.

[0008] Optionally, first conductive electromagnet blocks are provided at both ends of the control body, four sets of conductive sockets are connected to both sides of the control body close to the first conductive electromagnet blocks, and a fixing screw head is also installed at the bottom of the control body.

[0009] Optionally, the support assembly includes a landing gear, and a fixing screw hole is provided on the top of the landing gear. The fixing screw hole matches the fixing screw head structure, and the fixing screw hole and the fixing screw head are threadedly matched.

[0010] Optionally, the first propeller includes a first support frame, two groups of second conductive electromagnet blocks are installed at one end of the first support frame, the second conductive electromagnet blocks match the structure of the first conductive electromagnet blocks, the second conductive electromagnet blocks and the first conductive electromagnet blocks are magnetically matched, and positioning clips are also installed on both sides of the first support frame close to the second conductive electromagnet blocks.

[0011] Optionally, the second propeller includes a second supporting frame, and a positioning slot is provided on one side of the second supporting frame. The positioning slot matches the positioning card plate structure, and the positioning slot and the positioning card plate are snap-fitted.

[0012] Optionally, two groups of conductive card plates are installed on the side of the second support frame close to the positioning card slot, and the conductive card plates match the conductive card seat structure. The conductive card plates and the conductive card seat are snap-fitted together, and a strong magnetic layer is also provided on the side of the second support frame close to the two groups of conductive card plates.

[0013] In summary, the present invention has at least one of the following beneficial effects: 1. The modular aircraft designed in this scheme makes the process of disassembly, assembly, connection, maintenance and replacement more convenient through its unique connection method. When the propulsion assembly needs to be maintained or replaced, the staff only needs to use tools to release the magnetic engagement and easily remove the faulty first or second thruster for separate repair or replacement. If there is a problem with the landing gear, the fixing screw can be quickly unscrewed and it can be removed from the bottom of the fuselage. When installing a new component, the reverse order can be followed: first place the new component in the appropriate position, snap it into place, and then use magnetic attraction or threaded connection to fix it to the fuselage. This process does not require large-scale disassembly of the entire aircraft, greatly saving maintenance time and labor costs.

[0014] 2. The modular aircraft designed in this scheme brings many significant benefits through convenient disassembly and assembly. First, it greatly improves maintenance efficiency. Once a component fails, maintenance personnel can complete disassembly and replacement in the shortest time, reducing the time the aircraft is grounded due to maintenance and improving the availability of equipment; second, it reduces maintenance costs. Since there is no need for a comprehensive inspection and large-scale disassembly of the entire aircraft, the dependence on professional equipment and complex processes during maintenance is reduced, and the wear or damage of other components caused by disassembly and reassembly is also avoided; finally, the flexibility and adaptability of the aircraft are enhanced. Modules such as propulsion components can be quickly replaced and adjusted according to different mission requirements, enabling it to better adapt to changing flight environments and mission requirements, providing an efficient, economical and inventive solution for the field of aircraft technology.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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 efforts are within the scope of protection of the present invention.

[0019] Example: Refer to Figures 1 to 5 The present invention provides an embodiment of a modular aircraft, including a control fuselage 1, a support assembly 2 is installed at the bottom of the control fuselage 1, and propulsion assemblies 3 are distributed around the outer side of the control fuselage 1. The propulsion assembly 3 includes two groups of first propellers 4, which are respectively connected to the two ends of the control fuselage 1. Two groups of second propellers 5 are also provided on both sides of the control fuselage 1. When the modular aircraft needs to be functionally adjusted or repaired, the simple connection structure between the modules makes it easy for staff to quickly separate or assemble the corresponding components. If a propeller fails, it only needs to release the magnetic connection between it and the fuselage. The control fuselage 1 can be repaired or replaced individually by suction and snap-fitting, without the need for large-scale disassembly of the entire aircraft, which improves the flexibility and inventiveness of the equipment in the field of aircraft technology. A first conductive electromagnetic block 6 is provided at both ends of the control fuselage 1, and four groups of conductive card holders 7 are respectively connected to the two sides of the control fuselage 1 close to the first conductive electromagnetic block 6. A fixing screw head 8 is also installed at the bottom of the control fuselage 1. The control fuselage 1 can achieve rapid electrical docking between the propeller module and the fuselage module through the coordinated use of the first conductive electromagnetic block 6 and the conductive card holder 7, ensuring stable current transmission after the propeller module is powered on, and realizing modular plug-in and unplugging without cables and tools.

[0020] The support assembly 2 includes a landing gear 9, and a fixing screw hole 10 is provided on the top of the landing gear 9. The fixing screw hole 10 matches the structure of the fixing screw head 8. The fixing screw hole 10 and the fixing screw head 8 are threaded together. Through the structural design of the threaded matching between the fixing screw hole 10 and the fixing screw head 8, the landing gear 9 can be firmly connected and quickly disassembled and assembled with the control fuselage 1, thereby achieving stable support for the aircraft when taking off and landing on the ground and convenient maintenance and replacement of the landing gear 9. The first propeller 4 includes a first support frame body 11, and one end of the first support frame body 11 is equipped with two sets of second conductive electromagnetic blocks 12. The second conductive electromagnetic blocks 12 and The structures of the first conductive electromagnet block 6 are matched, and the second conductive electromagnet block 12 is magnetically matched with the first conductive electromagnet block 6. Positioning cards 13 are respectively installed on both sides of the first support frame 11 close to the second conductive electromagnet block 12. Through the structural design of magnetic matching between the second conductive electromagnet block 12 and the first conductive electromagnet block 6, rapid cable-free electrical connection and preliminary mechanical adsorption between the thruster module and the fuselage module can be achieved, ensuring stable current transmission and firm support of the thruster module. By installing the positioning cards 13 on both sides of the first support frame 11, precise alignment and reliable locking between the two groups of thruster modules can be achieved.

[0021] The second propeller 5 includes a second supporting frame 14, and a positioning slot 15 is provided on one side of the second supporting frame 14. The positioning slot 15 matches the structure of the positioning card plate 13, and the positioning slot 15 and the positioning card plate 13 are snap-fitted. Through the structural design of the snap-fitting between the positioning slot 15 and the positioning card plate 13, the second propeller 5 and the first propeller 4 can be accurately positioned and firmly connected, and the propulsion assembly 3 can be quickly connected and reliably fixed, ensuring the stability of the aircraft during flight, while facilitating the disassembly and maintenance of the propeller, thereby improving the assembly efficiency and maintenance convenience of the aircraft. The second supporting frame 14 is close to the positioning slot 15. Two groups of conductive card plates 16 are installed on one side, and the conductive card plates 16 match the conductive card seat 7 structure. The conductive card plates 16 and the conductive card seat 7 are snap-fitted together. A strong magnetic layer 17 is also provided on the side of the second support frame 14 close to the two groups of conductive card plates 16. Through the snap-fitting structural design between the conductive card plates 16 and the conductive card seat 7, the second propeller 5 can be quickly connected and electrically connected to the control fuselage 1 reliably, ensuring that the propeller module can stably receive power and signals. By adding a strong magnetic layer 17 on one side of the second support frame 14, the two groups of second support frames 14 snap-fitted on both sides of the control fuselage 1 can be magnetically fixed.

[0022] Working principle: The modular aircraft designed in this scheme is mainly composed of a control fuselage 1, a support assembly 2 and a propulsion assembly 3, wherein the propulsion assembly 3 includes a first propeller 4 and a second propeller 5. The second propeller 5 is connected by two groups of conductive card plates 16 installed on one side of the second support frame 14, and four groups of conductive card seats 7 installed on both sides of the control fuselage 1. Because the conductive card plates 16 match the conductive card seats 7 in structure, and the conductive card plates 16 and the conductive card seats 7 are snap-fitted, the four groups of second support frames 14 can be snap-fitted and fixed on both sides of the control fuselage 1, and with the strong magnetic layer 17 installed on one side of the second support frame 14, the two groups of second support frames 14 fixed on both sides of the control fuselage 1 are snap-fitted and fixed by magnetic attraction.

[0023] The modular aircraft designed in this scheme has positioning cards 13 installed on both sides of the first support frame 11, and a positioning slot 15 opened on one side of the second support frame 14. Since the positioning slot 15 matches the structure of the positioning card plate 13, and the positioning slot 15 and the positioning card plate 13 are snap-fitted, the first support frame 11 can be snap-fitted and fixed between the two groups of second support frames 14, and cooperate with the two groups of second conductive electromagnetic blocks 12 installed on one side of the first support frame 11, and the first conductive electromagnetic blocks 6 installed on both ends of the control fuselage 1. Since the second conductive electromagnetic blocks 12 match the structure of the first conductive electromagnetic blocks 6, and the second conductive electromagnetic blocks 12 and the first conductive electromagnetic blocks 6 are magnetically fitted, the first support frame 11 snap-fitted and fixed between the two groups of second support frames 14 can also be magnetically fixed to the control fuselage 1.

[0024] The modular aircraft designed in this scheme has a support assembly 2 installed at the bottom of the control fuselage 1. The support assembly 2 is connected to the bottom of the control fuselage 1 through a fixing screw hole 10 opened at the top of the landing gear 9 and a fixing screw head 8 installed at the bottom of the control fuselage 1. Since the fixing screw hole 10 matches the fixing screw head 8 in structure and the fixing screw hole 10 and the fixing screw head 8 are threadedly matched, the landing gear 9 can be connected and fixed to the bottom of the control fuselage 1, and the control fuselage 1 can also be disassembled, connected, repaired and replaced according to the usage of the landing gear 9.
