Description

Technical Field

[0001] This utility model relates to the field of aircraft model technology, and in particular to a movable canard connection structure for an aircraft model. Background Technology

[0002] Airplane models are scaled-down replicas of airplanes used for decoration, static display, and educational purposes. Most existing military-style airplane models are one-piece designs. For example, my country's main fighter jet, the J-20, nicknamed the "Eight-Armed Angel," features fully movable canards that are a major contributor to its high-flying capabilities. Existing airplane models cannot mimic dynamic canards, making it difficult for students to intuitively understand the aircraft's flight attitude during teaching or demonstrations, thus hindering airplane education and popular science dissemination. Utility Model Content

[0003] Therefore, it is necessary to provide a movable canard connection structure for an aircraft model to address the above problems.

[0004] A movable canard connection structure for an aircraft model includes a nose, fuselage, landing gear, and canards. The nose is mounted at the front of the fuselage, and three landing gears are arranged in a triangle at the lower end of the fuselage. Wings integral with the fuselage are provided on both sides of the fuselage, and two sets of canards are located at the front of the wings. Each canard includes a wingplate and a pivot. The pivot is mounted on the inner side of the wingplate and movably inserted into the fuselage. The inner side of the wingplate has several spaced constriction grooves along its extension direction, and several magnetic beads are installed one-to-one in the constriction grooves. The magnetic beads are magnetically attracted to the side of the fuselage.

[0005] Preferably, the pivot is located at the middle position inside the wing plate.

[0006] Preferably, an acrylic cockpit is adhered to the upper end of the head.

[0007] Preferably, a rubber ball is provided at the end of the rotating shaft.

[0008] Preferably, dustproof edges are also provided on both sides of the constriction groove.

[0009] Preferably, the surface of the fuselage is covered with carbon fiber.

[0010] The advantages of this invention are: by using magnetic beads to magnetically hold the fuselage in place, and using the pivot as the central axis for the rotation of the canard and the fuselage, the canard can achieve full-motion rotation in complete imitation of the real object, resulting in a higher degree of simulation in teaching and flight simulation.

[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 canard connection structure for an aircraft model includes a nose 1, a fuselage 2, landing gear 3, and canards 4. The nose 1 is mounted on the front end of the fuselage 2. The three landing gears 3 are arranged in a triangle at the lower end of the fuselage 2. Wings 21 integral with the fuselage 2 are provided on both sides of the fuselage 2. Two sets of canards 4 are located at the front end of the wing 21. Each canard 4 includes a wingplate 41 and a pivot 42. The pivot 42 is mounted on the inner side of the wingplate 41 and is movably inserted into the fuselage 2. The inner side of the wingplate 41 is provided with several spaced constriction grooves 411 along its extension direction. Several magnetic beads 43 are installed one-to-one in the constriction grooves 411. The magnetic beads 43 are magnetically attracted to the side of the fuselage 2. Specifically, in this embodiment, the nose 1 and the fuselage 2 are made of stainless steel, specifically martensitic stainless steel, which has strong magnetism. The metal nose 1 and fuselage 2 have high structural strength. A landing gear 3 is set at the lower part of the fuselage 2 to provide support and facilitate displacement using the rollers on the landing gear 3. The fuselage 2 has wings 21 on both sides, with canards 4 positioned at the leading edge of the wings 21. To enable the canards 21 to move, a constriction groove 411 is provided on the inner side where the canards 21 fit against the fuselage 2. The constriction groove 411 is used to embed magnetic beads 43, preventing them from detaching. A rotating shaft 42 is movably inserted into the fuselage 2, ensuring that the canards 4 can only rotate around the rotating shaft 42. The magnetic beads 43 are magnetically attracted to the fuselage 2, preventing the canards 4 from separating from the fuselage 2. Simultaneously, as the canards 4 rotate around the rotating shaft 42, the magnetic beads 43 roll and rub against the surface of the fuselage 2, reducing drag during rotation. The canard rotation provides a comprehensive simulation of the actual aircraft, allowing students to intuitively understand the flight attitude of this type of aircraft during teaching demonstrations.

[0017] like Figure 2 As shown, the pivot 42 is located in the middle of the inner side of the wing plate 41. When the canard 4 rotates, it avoids a large-angle misalignment between the edge of the canard 4 and the fuselage 2, so that the magnetic beads 43 are exposed.

[0018] like Figure 1 As shown, an acrylic cockpit 11 is attached to the upper end of the nose 1. The high-transparency acrylic cockpit 11 simulates the cockpit canopy of a real aircraft and restores the cockpit features of a stealth fighter.

[0019] like Figure 2 As shown, a rubber ball 421 is provided at the end of the rotating shaft 42. The rubber ball 421 at the end of the rotating shaft 42 is movably assembled inside the body 2. With the design that the diameter of the rubber ball 421 is slightly larger than the diameter of the rotating shaft 42, when the rotating shaft 42 is inserted into the body 2, the rubber ball 421 is compressed and passes through the channel, and then enters the body 2 to recover. This makes the rubber ball 421 play a locking role, preventing it from being magnetically attracted to the body 2 by the magnetic beads 43 alone.

[0020] like Figure 2 As shown, dustproof edges 412 are also provided on both sides of the constriction groove 411, so that when the canard 4 rotates, the dustproof edges 412 rub against the fuselage to remove the dust accumulated on the fuselage 2, and prevent dust from entering the gap between the magnetic bead 43 and the constriction groove 411, which could easily cause the magnetic bead 43 to get stuck.

[0021] Specifically, the surface of the fuselage 2 is covered with carbon fiber to prevent scratches on the surface of the fuselage 2.

[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.
