Abstract
Description
Technical Field
[0001] This utility model relates to the field of aircraft model technology, and in particular to a wing folding mechanism for a space shuttle model. Background Technology
[0002] For space shuttle models, the design and fabrication of wing folding mechanisms have multifaceted significance. On one hand, they enhance the model's realism, allowing model enthusiasts and aerospace aficionados to more intuitively understand the space shuttle's structure and working principles. On the other hand, research and practice on model wing folding mechanisms can help researchers better understand and solve some problems in real space shuttle wing folding technology, such as kinematic and dynamic analysis of the mechanism, material selection, and strength calculation. Furthermore, space shuttle model wing folding mechanisms can also serve as educational tools for aerospace science education, stimulating students' interest and passion for the aerospace industry and cultivating their scientific thinking and innovative abilities.
[0003] Currently, most space shuttle models on the market use simple hinges or plug-in structures for their component folding mechanisms. These mechanisms can only achieve static angle adjustments and cannot realistically simulate the dynamic folding and unfolding actions of the space shuttle during launch and reentry. These mechanisms usually rely on manual operation and lack automatic linkage functions, resulting in stiff movement and easy wear and loosening of the structure due to repeated operation. Therefore, they are inconvenient for daily use. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a wing folding mechanism for a space shuttle model. It aims to improve upon the existing technology where the folding mechanism of space shuttle models on the market generally adopts a simple hinge structure, which can only achieve static angle adjustment and cannot truly simulate the dynamic folding and unfolding actions of the space shuttle during launch and return. As a result, it lacks automatic linkage function, leading to stiff movement and problems such as wear and structural loosening caused by repeated operation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wing folding mechanism for a space shuttle model, comprising a U-shaped plate, a motor fixedly connected to the bottom right side of the U-shaped plate, a circular gear fixedly connected to the output end of the motor, an arc-shaped gear meshing with the outer wall of the circular gear, a folding shaft fixedly connected to the top inner side of the arc-shaped gear, connecting plates fixedly connected to the left and right sides of the outer wall of the folding shaft, and a U-shaped groove directly fixedly connected to the adjacent connecting plates.
[0006] As a further description of the above technical solution: A long plate is fixedly connected to the top inner side of the U-shaped plate.
[0007] As a further description of the above technical solution: A base plate is fixedly connected between the bottoms of the two connecting plates.
[0008] As a further description of the above technical solution: A mounting plate is fixedly connected to the bottom left side of the U-shaped plate.
[0009] As a further description of the above technical solution: The left and right ends of the folding shaft are rotatably connected to the inner rear end of the U-shaped plate.
[0010] This utility model has the following beneficial effects: 1. In this utility model, the motor is started to provide power, which is transmitted through the transmission shaft to the circular gear and the arc gear mounted on the folding shaft of the wing. At this time, the circular gear and the arc gear mesh with each other and rotate under the drive of the circular gear. In this process, the meshing of the circular gear and the arc gear ensures the stability and accuracy of the transmission, so that the wing can be folded and unfolded smoothly according to the design requirements. Therefore, it can effectively fold the wing and provide a certain degree of convenience. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model is provided: a wing folding mechanism for a space shuttle model, including a U-shaped plate 1, a motor 2 fixedly connected to the bottom right side of the U-shaped plate 1, a circular gear 3 fixedly connected to the output end of the motor 2, an arc gear 4 meshing with the outer wall of the circular gear 3, a folding shaft 5 fixedly connected to the top inner side of the arc gear 4, connecting plates 8 fixedly connected to the left and right sides of the outer wall of the folding shaft 5, and a U-shaped groove 6 directly fixedly connected to the adjacent connecting plates 8. Specifically, motor 2 serves as the power source and is the core driving force for the entire structure's operation. The output end of motor 2 is fixedly connected to circular gear 3 via a coupling. When motor 2 starts, it drives circular gear 3 to rotate at high speed and smoothly. The outer wall of circular gear 3 is tightly meshed with arc gear 4. The rotation of circular gear 3 precisely drives arc gear 4 to move synchronously. The inner top of arc gear 4 is cleverly fixedly connected to folding shaft 5. Folding shaft 5, as a transmission component, rotates with the movement of arc gear 4. Two connecting plates 8 are parallel to each other and structurally robust. A U-shaped groove 6 is directly fixedly connected between adjacent connecting plates 8. The U-shaped groove 6 may be used for accommodating functions. With the rotation of folding shaft 5, the entire structure can achieve folding and unfolding actions. Please see the appendix Figure 4 - Appendix Figure 6 A base plate 9 is fixedly connected between the bottoms of the two connecting plates 8, a mounting plate 10 is fixedly connected to the bottom left side of the U-shaped plate 1, a long plate 7 is fixedly connected to the top inner side of the U-shaped plate 1, and the left and right ends of the folding shaft 5 are rotatably connected to the rear inner side of the U-shaped plate 1. Specifically, the U-shaped plate 1 serves as the key frame of the entire mechanical structure, and it is fixedly connected to the mounting plate 10. The mounting plate 10 has multiple mounting holes. The inner top of the U-shaped plate 1 is also fixedly connected to the long plate 7, which is straight and sturdy. The folding shaft 5 is the core component for realizing the folding function. This rotating connection method allows the folding shaft 5 to rotate flexibly under the drive of the motor 2, thereby driving the connecting plate 8 and the base plate 9 connected to it to realize the folding and unfolding actions.
[0015] Working principle: Power is provided by starting motor 2, which is transmitted through the transmission shaft to circular gear 3 and arc gear 4, which are mounted on the folding shaft 5 of the wing. At this time, they mesh with circular gear 3 and rotate under the drive of circular gear 3, which in turn drives folding shaft 5 to rotate, thereby realizing the folding and unfolding action of the wing around folding shaft 5. In this process, the meshing of circular gear 3 and arc gear 4 ensures the stability and accuracy of transmission, so that the wing can be folded and unfolded smoothly according to design requirements. Therefore, it can effectively fold the wing and provide a certain degree of convenience.
[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
