[0001] This utility model relates to the field of aircraft model technology, specifically to an aerodynamic sound-generating aircraft assembly model. Background Technology

[0002] Aircraft models generally refer to replicas made to scale from real aircraft, including static scale models and remote-controlled models. Static scale models are mainly used for assembly, display, collection, and appreciation, and can also be used for educational purposes, focusing on reproducing the details of real aircraft. Remote-controlled models are aircraft models that can be remotely controlled to fly, emphasizing aerodynamic and flight performance, and are generally used for scientific and technological practice, sports and entertainment, as well as professional competitions and applications.

[0003] Remote-controlled model airplanes are relatively difficult to operate and costly, making them more challenging for science education and unsuitable for young children. Static scale models, on the other hand, generally only allow for observation of the aircraft's shape after assembly, resulting in a limited functionality. Utility Model Content

[0025] This invention proposes a pneumatically sound-generating aircraft assembly model.

[0026] Please refer to Figures 1 to 6 To achieve the above objectives, the aerodynamic sound-generating aircraft assembly model proposed in this utility model includes a nose module 10, a fuselage module 20, a tail module 30, a cockpit module 40, an aerodynamic sound-generating module 50, and two wing modules 60. The nose module 10, fuselage module 20, and tail module 30 are all hollow structures, and are sequentially and detachably connected to form a through airflow resonance cavity. A nozzle 11 for communicating with the airflow resonance cavity is formed on the side of the nose module 10 opposite to the fuselage module 20, and an airflow outlet communicating with the airflow resonance cavity is formed on the side of the tail module 30 opposite to the fuselage module 20. The two wing modules 60 are symmetrically and detachably connected to both sides of the fuselage module 20. The aerodynamic sound-generating module 50 is connected to the fuselage module 20. The cockpit module 40 is connected to the fuselage module 20.

[0027] The present invention provides an aerodynamic sound-generating aircraft assembly model, comprising a detachably connected nose module 10, fuselage module 20, tail module 30, cockpit module 40, aerodynamic sound-generating module 50, and two wing modules 60. The nose module 10, fuselage module 20, and tail module 30 are sequentially and detachably connected to form a through-flow resonant cavity. A nozzle 11 for connecting to the resonant cavity is formed on the side of the nose module 10 opposite to the fuselage module 20, and an airflow outlet communicating with the resonant cavity is formed on the side of the tail module 30 opposite to the fuselage module 20. The fuselage module 20 is connected to the aerodynamic sound-generating module 50. Sound module 50; Therefore, in addition to assembling the various modules of the model to understand the structure of the aircraft, the technical solution of this utility model can also blow air into the airflow resonance cavity through the mouthpiece 11 to drive the aerodynamic sound module 50 to produce sound. It combines the modular structure of the J-5 fighter jet with the acoustic components of aerodynamic sound generation to form a linkage design of "aerodynamic shape-airflow path-sound generation mechanism". In addition, during the assembly, playing and adjustment process, it simultaneously conveys knowledge of aviation history, physics and acoustics, realizing the integrated design of play and teaching tools. Therefore, this utility model is conducive to solving the problem that the existing aircraft assembly model can only be used to observe the shape of the aircraft, resulting in the relatively simple function of the aircraft assembly model.

[0028] Specifically, the various assembly modules of the aircraft model can be combined to form a fighter jet, such as the J-5 fighter jet or other types of fighter jets. This invention focuses on "structural assembly + airflow sound generation + popular science understanding," modularly recreating the aerodynamic shape of an aircraft. Utilizing the nose air intake, it integrates a diaphragm vibration sound generation mechanism into the fuselage, allowing users to understand the relationship between aircraft structure, aerodynamics, and acoustics while assembling the toy, achieving "learning through play." The nose module 10 has a built-in nozzle 11 (i.e., the J-5 aircraft's air intake), which connects to the internal airflow channel of the fuselage. The nozzle 11 is made of food-grade material and fits snugly to the lips.

[0029] This utility model can refer to the classic structure of the J-5 fighter jet: single-seat, nose air intake, swept wings, single vertical tail, etc., and is divided into 5 core assembly modules and an aerodynamic sound generation module 50. Among them, the wing module 60 is symmetrical and adopts a swept wing design. The tail module 30 includes a horizontal tail 32 and a vertical tail 31. The cockpit module 40 needs to be closely integrated with the airframe to achieve good airtightness.

[0030] Specifically, the module assembly in this utility model must follow the aerodynamic structural logic of the aircraft (such as the wings must be installed symmetrically, otherwise the airflow will be turbulent and the sound will be harsh), guiding users to understand the impact of structural integrity on the performance of the aircraft.

[0031] Optionally, the fuselage module 20 has a through hole communicating with the internal space of the fuselage module 20, and the pneumatic sound-generating module 50 includes a diaphragm mounting groove 53 and a locking component 51; the diaphragm mounting groove 53 is connected to the through hole so that the through hole is closed by a sound-generating diaphragm installed in the diaphragm mounting groove 53, and the diaphragm mounting groove 53 extends in a direction away from the fuselage module 20 to form a connecting structure 52, and the locking component 51 is used to connect the connecting structure 52 to fix the sound-generating diaphragm; the locking component 51 has an opening opposite to the sound-generating diaphragm.

[0032] Specifically, in this invention, after the aircraft model is assembled, airflow is blown into the airflow resonance cavity through the nozzle 11. The airflow vibrates the sound-generating diaphragm installed in the diaphragm mounting slot 53, thereby producing sound. The locking component 51 is used to connect to the connecting structure 52 to fix the sound-generating diaphragm installed in the diaphragm mounting slot 53. The locking component 51 has an opening opposite to the sound-generating diaphragm, so that one side of the diaphragm is an airflow resonance cavity, and the other side is connected to the atmosphere, which is beneficial for the diaphragm to vibrate and produce sound under the action of airflow.

[0033] The sound-generating mechanism of this invention is as follows: sound is generated through vibration. The structure is simple, consisting of a mouthpiece 11 and a resonance chamber, with the body serving as the resonance chamber. The PE diaphragm inside the body module 20 is located at the front of the airflow resonance chamber. When the user blows air from the mouthpiece 11, the airflow flows along the internal channel of the body, impacting the diaphragm and causing it to vibrate and generate sound.

[0034] Optionally, the locking component 51 and the connecting structure 52 are detachably connected. For example, detachable methods such as snap-fit ​​connections and threaded connections are also included within the protection scope of this utility model.

[0035] Optionally, the connecting structure 52 has an internal thread, and the locking component 51 is a locking bolt. The locking component 51 is connected to the connecting structure 52 using a threaded connection. The advantage of using a threaded connection is that it not only secures the sound-generating diaphragm but also allows for easy and convenient disassembly and installation of the locking bolt, thus improving the ease of replacing the sound-generating diaphragm.

[0036] Optionally, the aerodynamic sound-generating aircraft assembly model includes sound-generating diaphragms of various thicknesses. The diaphragm mounting groove 53 is used to install one type of sound-generating diaphragm and is locked in place by the locking component 51. Specifically, the thickness of the sound-generating diaphragm is not limited; for example, it can be two or more types. In this embodiment, three thicknesses of sound-generating diaphragms are provided, with the thickness increasing sequentially. Replacing different sound-generating diaphragms can change the timbre; the thinner diaphragm has a higher pitch, while the thicker diaphragm has a lower pitch, simulating the engine sounds of different aircraft models and expanding the model's sound effects.

[0037] Optionally, the nose module 10, the fuselage module 20, and the tail module 30 are connected by mortise and tenon joints, the two wing modules 60 are connected to the fuselage module 20 by mortise and tenon joints, and the cockpit module 40 is connected to the top of the fuselage module 20 by mortise and tenon joints. The mortise and tenon joint connection method is simple and convenient, improving the ease of model assembly and reducing the assembly difficulty for beginners. It also features easy disassembly and repeated assembly / disassembly.

[0038] Optionally, the nose module 10, fuselage module 20, tail module 30, cockpit module 40, aerodynamic sound generation module 50, and wing modules 60 are all PLA plastic structural components. Specifically, all modules of the model in this utility model are made of environmentally friendly PLA (Polylactic Acid) plastic, and each module can be combined with a rounded corner design, making it suitable for children over 3 years old. The modules are connected by a mortise and tenon joint, allowing for repeated disassembly.

[0039] Optionally, the tail fin module 30 includes a main structure 33, a vertical tail fin 31, and two horizontal tail fins 32. The main structure 33 is used to communicate with the fuselage module 20 to form part of the airflow resonance cavity. The airflow outlet is formed on the side of the main structure 33 away from the fuselage module 20. One end of the vertical tail fin 31 is connected to the end of the main structure 33 near the airflow outlet, and the other end extends obliquely upward toward the main structure 33. The two horizontal tail fins 32 are respectively located on both sides of the vertical tail fin 31.

[0040] Optionally, the cockpit module 40 is connected to the top of the fuselage module 20, and the pneumatic sound-generating module 50 is disposed on the underside of the fuselage module 20. Specifically, a diaphragm mounting slot 53 is reserved on the underside of the fuselage module 20, so that the cockpit module 40 and the pneumatic sound-generating module 50 are arranged opposite to each other.

[0041] Optionally, the sound-generating diaphragm is a PE diaphragm. Specifically, the PE diaphragm uses a replaceable food-grade PE film.

[0042] Applicable scenarios and user value of this utility model: Children's toys: Children aged 3-10 can develop their hands-on skills through assembly, gain fun by blowing air to make sounds, and at the same time subtly absorb aviation and acoustic knowledge, imitate the sound of airplanes flying, increase the functionality of the assembled models, and combine visual and auditory experiences.

[0043] Science teaching aids: These can be used in primary and secondary school science classes to demonstrate knowledge points such as "aerodynamics" and "sound production," and are intuitive and highly interactive.

[0044] Collectibles / Cultural and Creative Products: As a classic aircraft model, the J-5's highly realistic modular design can attract military enthusiasts, combining aesthetic appeal with interactivity.

[0045] Through the above design, this toy can not only satisfy the fun of assembling structural toys, but also allow users to understand interdisciplinary knowledge through interaction, demonstrating strong innovation and market potential.
