Description

Technical Field

[0001] This utility model relates to the field of aircraft model technology, and in particular to a movable aircraft model wing. Background Technology

[0002] Aircraft models are primarily used for collection, display, and education. They are non-flying and scaled down (e.g., 1:400 passenger plane models, 1:72 fighter jet models), made from materials including metal and ABS resin. Currently, when manufacturing fighter jet models, such as the J-20, China's new generation of main fighter jets, the wingtips of aircraft like the J-20 are movable, while most aircraft models are one-piece with fixed wingtips, making a 1:1 full simulation impossible. A small number of aircraft models use hinge structures to connect the wingtips to the main wing in order to achieve movable wingtips. These hinge structures are installed on the outside of the wing, affecting the aesthetic appearance of the aircraft. Furthermore, when displayed outdoors, the hinges are prone to rust from rain over time, with rust adhering to the wings, reducing the display effect, and cleaning the rust is extremely inconvenient. Utility Model Content

[0003] Therefore, it is necessary to provide a movable aircraft model wing to address the above problems.

[0004] A movable model wing for an aircraft includes a wing body and a side wing, and also includes a connector. The connector includes several rubber strips and a snap-fit ​​part. The several rubber strips are embedded in the wing body in a straight line at intervals. The outer ends of the rubber strips are connected to the snap-fit ​​parts. A slot is provided on the side of the side wing adjacent to the wing body, and the snap-fit ​​part snaps into the slot.

[0005] Preferably, the wing body and the sidewalls adjacent to each other are provided with corresponding magnetic positioning blocks.

[0006] Preferably, the diameter of the slot opening gradually decreases towards the wing body side, the locking part is made of rubber, and the root of the locking part connected to the rubber strip is provided with a serrated strip that matches the inner wall of the slot opening, and the serrated strips of several locking parts are connected as one piece.

[0007] Preferably, the side wing includes a frame and a skin, wherein the frame is a frame structure made of welded aluminum alloy, and the skin is attached to the surface of the frame.

[0008] Preferably, the skin is made of carbon fiber.

[0009] Preferably, a plug is detachably installed at the end of the slot, and the plug is connected to the frame by bolts.

[0010] The advantages of this utility model are: by using the slot and the snap-fit ​​part to connect the side wing and the wing body into one piece, and by benefiting from the stretchable characteristics of the rubber strip, the side wing can be flipped, realizing the side wing's highly realistic moving function, making the model more realistic, eliminating the need for hinge connection, and the connection between the wing body and the side wing is compact, more beautiful, and has an excellent display effect.

[0012] Figure 2 This is a schematic diagram of the explosion of the wing of a movable airplane model. Detailed Implementation

[0013] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0014] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0016] like Figures 1-2As shown, a movable airplane model wing includes a wing body 1 and a side wing 2, and a connector 3. The connector 3 includes several rubber strips 31 and snap-fit ​​parts 32. The rubber strips 31 are embedded in the wing body 1 in a straight line at intervals. The outer ends of the rubber strips 31 are connected to the snap-fit ​​parts 32. A slot 21 is provided on the side of the side wing 2 adjacent to the wing body 1, and the snap-fit ​​parts 32 snap into the slot 21. Specifically, in this embodiment, the wing body 1 and the side wing 2 are connected by the connector 3, so that the side wing 2 can be flipped up or down around the wing body 1. The connector 3 is hidden between the wing body 1 and the side wing 2, with no external exposure, resulting in a good aesthetic appearance and improved user experience. The connector 3 includes several rubber strips 31 and snap-fit ​​parts 32. The rubber strips 31 can be directly glued into the pre-set holes in the wing body 1 by injection. The snap-fit ​​parts 32 are provided at the outer ends of the rubber strips 31 that protrude from the wing body 1. The shape of the snap-fit ​​parts 32 can be spherical, conical, or square, etc., without specific limitations, as long as its cross-sectional area is larger than that of the rubber strips 31. The snap-fit ​​parts 32 snap into the slots 21 at the ends of the wing 2. By utilizing the cooperation between the slots 21 and the snap-fit ​​parts 32, the wing 2 and the wing body 1 are connected as one unit. Benefiting from the extensibility of the rubber strips 31, the wing 2 can be flipped, realizing a highly realistic wing movement function. The model is more realistic, and there is no need to use hinges for connection. The connection between the wing body 1 and the wing 2 is compact, more aesthetically pleasing, and has an excellent display effect.

[0017] like Figure 2 As shown, the wing body 1 and the side wing 2 are respectively provided with corresponding magnetic positioning blocks 11. When the side wing 2 is flipped, the distance between the side wing 2 and the wing body 1 increases. When resetting, the magnetic positioning blocks 11 on the wing body 1 and the magnetic positioning holes 11 on the side wing 2 are magnetically connected to each other, so that the side wing 2 and the wing body 1 are re-aligned. After the side wing 2 and the wing body 1 are flipped and reset, the probability of the side wing 2 being misaligned or offset is reduced.

[0018] like Figure 2As shown, the diameter of the slot 21 gradually decreases towards the wing body 1. The locking part 32 is made of rubber. The root of the locking part 32 connected to the rubber strip 31 is provided with a serrated strip 321 that matches the inner wall of the slot 21. The serrated strips 321 of several locking parts 32 are connected as one piece. Specifically, during outdoor displays, the wing 2, under the elastic force of the rubber strip 31, is tightly pressed against the wing body 1. At this time, the serrated strip 321 at the root of the locking part 32, under the elastic tension applied by the rubber strip 31, deforms and fits into the locking groove 21. The serrated strip 321 is then compressed and deformed by the inner wall of the locking groove 21, and several serrated strips 321 are connected as a whole, matching the linear arrangement of the rubber strip 31, also forming a linear shape. This seals the opening of the locking groove 21, preventing rainwater from dripping down the gap between the wing 2 and the wing body 1 during outdoor displays and entering the locking groove 21, thus preventing water accumulation and corrosion inside the locking groove 21. The serrated strip 321 and the opening of the locking groove 21 cooperate to form multiple sealing lines, effectively blocking liquid leakage. The compression deformation is more than 30% higher than that of ordinary sealing strips, effectively enhancing the sealing performance.

[0019] like Figure 2 As shown, the side wing 2 includes a frame 22 and a skin 23. The frame 22 is a frame structure made of welded aluminum alloy, and the skin 23 is attached to the surface of the frame 22. Specifically, the combination design of the frame 22 and the skin 23 is adopted to achieve the purpose of lightweighting, so as to avoid the side wing 2 being too heavy and the rubber strip 31 being subjected to excessive tensile force when flipping, which would cause the rubber strip 31 to be overstretched, permanently deformed and lose its elasticity.

[0020] Specifically, the skin 22 is made of carbon fiber. The density of carbon fiber is only 1.7-2.0 g / cm³. 3 Approximately 7.8 g / cm³ of steel. 3 1 / 4 of ) aluminum alloy (2.7g / cm) 3 Carbon fiber skin can reduce structural weight by 30%-50%, while its tensile strength can reach 3000-6000MPa (compared to approximately 300-800MPa for steel). Replacing traditional metal skin with carbon fiber skin can reduce structural weight by 30%-50%, and carbon fiber skin can provide higher structural stability and reduce deformation.

[0021] like Figures 1-2As shown, a plug 4 is detachably installed at the end of the slot 21, and the plug 4 is connected to the frame 22 by bolts. Specifically, in this embodiment, when the side wing 2 is assembled with the wing body 1, several rubber strips 31 are arranged linearly. In order to facilitate the insertion of the snap-fit ​​part 32 into the slot 21, the assembly starts from the first snap-fit ​​part 32 at the beginning of the row. After all the snap-fit ​​parts 32 are inserted into the slot 21 in sequence, the end of the slot 21 is blocked with the plug 4 to prevent it from falling off. It can be understood that the other end of the slot 21 is sealed, thus completing the assembly of the side wing.

[0022] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
