Abstract
Description
Technical Field
[0001] The utility model relates to the field of unmanned aerial vehicles, in particular to an electromagnetic - iron adsorption - type wing - tip connection mechanism. Background Technique
[0002] The chain - wing technology refers to the in - atmosphere air connection and separation technology in which multiple fixed - wing unmanned aerial vehicles are connected by wing - tip connection mechanisms to form a large aspect - ratio unmanned aerial vehicle composite. Among them, a single fixed - wing unmanned aerial vehicle to be connected is also called an unmanned flight unit. The wing - tip chain - wing technology can enable the aircraft to have better aerodynamic performance, structural strength, and complex multi - task adaptability, fly higher, have a longer endurance time, and perform tasks more flexibly and diversely.
[0003] The wing - tip connection mechanism is a key component for realizing the combination of unmanned aerial vehicle wing tips. However, there are many technical problems with the mechanical connection mechanisms widely used in the current air docking of unmanned aerial vehicle flight units:
[0004] First, the structure is complex and the weight is relatively large. Traditional mechanical connection mechanisms often have a complex structure and require multiple components to work together. This not only increases the overall weight but also raises the difficulty of design, manufacturing, and assembly, reducing reliability. For unmanned flight units, weight is an important factor affecting flight performance, and excessive connecting components will lead to a decrease in flight efficiency.
[0005] Second, maintenance is difficult. Traditional connection methods require frequent maintenance and inspection. Especially when fasteners such as bolts and pins are stressed, loosening and wear are likely to occur. This means that in practical applications, more resources need to be invested in regular inspections and replacements, increasing the operation and maintenance costs and affecting the continuity of flight missions.
[0006] Third, the mechanical properties are insufficient. When the unmanned aerial vehicle composite is in flight states such as pitching, rolling, and yawing, a large moment difference will be generated between multiple unmanned aerial vehicle flight units. These moment differences will be transmitted to the connection mechanism. If the strength and stiffness of the connection mechanism are not high enough, it may cause damage or failure of the connection part, seriously affecting flight safety. Therefore, the mechanical properties of the connection mechanism are crucial for the reliability of the entire system.

The fixing method not described in the text can be any fixing method such as thread fixing, bolt fixing or glue bonding.
[0036] Embodiment 1: In combination with all the accompanying drawings; The electromagnet adsorption type wing tip connection mechanism is characterized in that:
[0037] The connecting mechanism comprises a left groove connecting piece and a right convex connecting piece;
[0038] A plate 5 is arranged on the left groove connector, and the plate 5 includes a hinge space 6, and the cross section of the hinge space 6 is V-shaped;
[0039] The right convex connector can fit into the hinge space 6;
[0040] The right convex connector is provided with a convex connector hole 10.
[0041] The plate 5 is also provided with a perforation 3;
[0042] There is an electromagnet 4 on the plate 5, which also includes an iron plate cone 7 that can pass through the convex connector hole 10 and the perforation 3. The substantial technical effect of the technical solution here and its implementation process, that is, the basic function, are as follows: In order to overcome the deficiencies in the above-mentioned prior art, a new, reliable, lightweight and easy-to-maintain connection mechanism is needed. With the development of materials science and electromagnetic technology, the introduction of the electromagnet adsorption connection mechanism provides a new solution to the problem of aerial docking of unmanned aerial vehicle flight units. This new connection mechanism utilizes the principle of electromagnet adsorption, simplifies the structural design, reduces weight and improves mechanical properties, thereby effectively improving the overall flight performance and safety of the unmanned flight unit chain-wing combination platform.
[0043] The purpose of the utility model is to provide a novel connection mechanism solution for aerial docking of UAV flight units, which improves the reliability of connection and simplifies separation operation through an electromagnet adsorption design.
[0044] The utility model proposes an electromagnet adsorption type connection mechanism, comprising an electromagnet, an iron sheet round table, a left groove connection piece and a right convex connection piece. The entire connection mechanism is docked with the right convex connection piece through the left groove connection piece, the iron sheet round table passes through the circular hole in the middle of the right convex connection piece, and the electromagnet is energized to adsorb the iron sheet round table, thereby achieving locking. When separation is required, the iron sheet round table connection piece is automatically detached by gravity through power-off operation, and easy separation is achieved by cooperating with the speed difference between the two flight units.
[0045] The iron sheet frustum is a frustum-shaped structure and is adsorbed and locked by an electromagnet.
[0046] The left groove connector is installed at the wing tip of the left unmanned flight unit.
[0047] The right convex connector is installed at the wing tip of the right unmanned flight unit and is provided with a middle round hole for the iron sheet frustum connector to pass through.
[0048] During the flight of the chain wing, the left groove connector is docked with the right convex connector, and the iron sheet frustum connector passes through the middle round hole of the right convex connector. The electromagnet is energized to adsorb the iron sheet frustum connector, thereby realizing the locking of the connecting mechanism. At this time, the connecting mechanism can effectively withstand the torque difference between the two unmanned flight units, ensuring the stability and safety of the flight.
[0049] When aerial separation is required, the electromagnet is powered off, and the iron sheet frustum connector falls off by its own weight under the action of gravity. At the same time, the left unmanned flight unit accelerates and the right unmanned flight unit decelerates, and separation is achieved through the speed difference. This design effectively reduces the impact and damage that may occur during the separation process, improving the reliability and operational simplicity of the system.
[0050] Embodiment 2: As a further improvable solution or a parallel solution or an alternative independent solution, the lower part of the iron sheet frustum 7 is a conical structure. The substantial technical effect and its implementation process, that is, the basic function, of the technical solution here are as follows: namely, the frustum structure, with reliable locking.
[0051] Embodiment 3: As a further improvable solution or a parallel solution or an alternative independent solution, the electromagnet 4 is energized to attract the iron sheet frustum 7, thereby realizing locking; when separation is required, the iron sheet frustum 7 connector falls off by its own weight under the action of gravity through a power-off operation, and separation is achieved easily in cooperation with the speed difference between the two flight units. The substantial technical effect and its implementation process, that is, the basic function, of the technical solution here are as follows: making full use of gravity.
[0052] Embodiment 4: As a further improvable solution or a parallel solution or an alternative independent solution, the left groove connector and the right convex connector are each located on one flight unit.
[0053] Embodiment 5: As a further improvable solution or a parallel solution or an alternative independent solution, the left groove connector and the right convex connector are each located on the flight wings of the flight unit.
[0054] Compared with the defects of the prior art, "firstly, the structure is complex and the weight is relatively large. Traditional mechanical connection mechanisms often have a complex structure and require multiple components to work together. This not only increases the overall weight but also raises the difficulties in design, manufacturing, and assembly, and reduces the reliability. For unmanned flight units, weight is an important factor affecting flight performance, and excessive connecting components will lead to a decline in flight efficiency." The structure of this patent is simple and the weight is very small, which will not impose any extra burden on the unmanned aerial vehicle unit or the aircraft unit and will not affect the overall flight and separation flight.
[0055] Compared with the defects of the prior art, "secondly, maintenance is difficult. Traditional connection methods require frequent maintenance and inspection. Especially when fasteners such as bolts and pins are under stress, loosening and wear are likely to occur. This means that in practical applications, more resources need to be invested in regular inspections and replacements, increasing the operation and maintenance costs and affecting the continuity of flight missions." This patent is easy to maintain, will not show wear, and can be used multiple times.
[0056] Compared with the defects of the prior art, "thirdly, the mechanical properties are insufficient. When the unmanned aerial vehicle combination is in flight states such as pitching, rolling, and yawing, a large moment difference will be generated between multiple unmanned aerial vehicle flight units. These moment differences will be transmitted to the connection mechanism. If the strength and stiffness of the connection mechanism are not high enough, it may cause damage or failure of the connection part, seriously affecting flight safety. Therefore, the mechanical properties of the connection mechanism are crucial to the reliability of the entire system." The electromagnet of this patent has a strong adsorption force. Because it is hinged, it also has a certain degree of rotational freedom and is more flexible. If the torque is too large, it will not damage the wing. At most, it will be forced to separate and disengage.
[0057] Embodiment 6: As a further improvable solution, a parallel solution, or an alternative independent solution, the electromagnet 4 is a remotely controlled electromagnet. The substantial technical effects achieved by the technical solution herein and its implementation process, that is, the basic functions, are as follows: It can achieve remote control.
[0058] Innovatively, the above-mentioned effects exist independently, and the combination of the above results can also be achieved with a set of structures. It should be noted that multiple modules of this patent are the integration of modules in the prior art and do not involve new modules. Even if some modules use programs, these programs undoubtedly belong to known programs.
[0059] It should be noted that the multiple solutions provided by this patent include their basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve the co-realization of multiple effects.
[0060] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the claimed utility model.
