Description

Technical Field

[0001] This utility model relates to the technical field of astronomical teaching and popular science display equipment, and in particular to a dynamic demonstration device for the solar system home. Background Technology

[0002] In the fields of astronomical science education and dissemination of scientific knowledge, solar system models, as important tools for intuitively demonstrating the distribution and motion patterns of planets, are widely used in school classrooms, science museum exhibitions, and the cultivation of astronomical interests among young people. With the increasing public demand for astronomical knowledge and the diversification of educational methods, traditional static models can no longer meet people's needs for visualized and perceptible planetary motion. Demonstration devices that can dynamically present the state of planetary motion are gradually becoming important equipment in science popularization and teaching scenarios. Their performance optimization and functional improvement are of great significance for enhancing the effectiveness of astronomical knowledge transmission.

[0003] Currently available dynamic solar system demonstration devices on the market mostly employ fixed transmission structure designs to simulate planetary motion. While some devices can simulate planetary revolution, the fixed gear ratios prevent them from accurately depicting the actual trajectories of different planets in the solar system, as well as the effects of revolution and rotation, leading to discrepancies between the demonstration and scientific facts. Furthermore, existing devices often use integrated or complex bolted connections between the planetary spheres and transmission components. When different sizes or styles of planetary spheres are needed to suit different teaching themes, or when planetary spheres are damaged and require repair or replacement, multiple components often need to be disassembled using specialized tools. This cumbersome and time-consuming process can cause unnecessary damage to the transmission structure during disassembly and reassembly, affecting the long-term stability and practicality of the device.

[0004] In response to this technical problem, this application proposes a dynamic demonstration device for a solar system home. Utility Model Content

Through a drive and gear structure, it can reproduce the laws of planetary motion and improve the effect of knowledge transmission. It also features a tool-free disassembly and assembly structure, which allows for quick replacement and repair of planetary spheres, preventing the device from being out of service due to component damage. This solves the problem of difficult adjustment in existing devices and enhances practicality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A dynamic demonstration device for a solar system home includes a star sphere and a base.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Reference Figures 2-4 This utility model provides an embodiment of a dynamic demonstration device for a solar system home, comprising a star sphere 1 and a base 2. A rotating plate 4 is fixedly connected to the lower side of the star sphere 1, and the bottom end of the rotating plate 4 is rotatably connected to the upper side of the outer wall of the base 2. A motor 6 is installed inside the base 2, and the rotating end of the motor 6 is fixedly connected to the bottom end of the rotating plate 4. A rotating ring 5 is rotatably connected to the upper side of the rotating plate 4, and a fixing ring 8 is fixedly connected to the upper outer wall of the rotating plate 4. The outer wall of the fixing ring 8 is located outside the rotating ring 5. A transmission gear 12 is rotatably connected to the upper inner side of the rotating ring 5. A housing 13 is provided on the upper outer wall of the rotating ring 5, and a hole is opened on the lower inner wall of the housing 13. A movable ball 18 is installed inside the hole. A connecting rod is fixedly connected to the bottom end of a planetary sphere 3, and a groove is opened on the lower outer wall of the connecting rod. The transmission gear 12 is connected to the planetary sphere 3 through a fixing component.

[0020] Specifically, during use, the upper rotating plate 4 and the stellar sphere 1 can be rotated by starting the motor 6. The first gear ring 11 on the outer side of the rotating plate 4 meshes with the third adjusting gear 10. The rotation of the rotating plate 4 drives the rotation of the third adjusting gear 10 and the second adjusting gear 9. The second adjusting gear 9 meshes with the third gear ring 20, thereby driving the rotation of the entire rotating ring 5. Because of the rotation of the rotating ring 5, the upper planetary sphere 3 revolves around the central stellar sphere 1. Since there is a fixed ring 8 on the outer side of the rotating ring 5, and a fourth gear ring 21 is fixed to the side of the fixed ring 8, it interacts with the planetary sphere. The lower transmission gear 12 is engaged with the planetary ball 3. While the rotating ring 5 drives the planetary ball 3 to revolve, the lower gear 12 is engaged with the fourth toothed ring 21, which causes the planetary ball 3 to rotate. The second toothed ring 19 on the lower side of the rotating ring 5 is engaged with the first adjusting gear 7 on the outer side. This process can be repeated to control all the planetary balls 3 and the number of gears and the number of teeth in the middle of the rotating rings 5 ​​on both sides, thereby adjusting the speed ratio and rotation direction. By controlling the tooth ratio between the transmission gear 12 and the fourth toothed ring 21, the rotation speed ratio of each planetary ball 3 can be controlled, making the model more intuitive to view. Furthermore, during use, the planetary ball 3 can be quickly rotated and disassembled for replacement. The limiting ring 14 on the side of the housing 13 can be rotated. When the housing 13 moves downward, the internal connecting shaft will move downward, causing the fixed ball 17 to move downward. The movable ball 18 will then lose the constraint of the fixed ball 17 and slide backward. After the movable ball 18 is displaced, the constraint force on the lower side of the planetary ball 3 will disappear. The same principle applies to installation. When the limiting ring 14 is rotated upward, the internal spring 15 will give the baffle an upward force, thereby moving the fixed ball 17 upward. The movable ball 18 will be squeezed into the hole, thereby constraining the groove on the lower side of the connecting rod. The cross groove on the lower side of the connecting rod is connected to the tenon on the upper side of the transmission gear 12, which can ensure the transmission effect of the transmission gear 12.

[0021] Reference Figure 1 , Figure 3 and Figure 5An auxiliary rod 16 is slidably connected to the lower outer wall of the housing 13. A fixed ball 17 is fixedly connected to the lower end of the auxiliary rod 16, and the outer wall of the fixed ball 17 is positioned above the movable ball 18.

A fourth toothed ring 21 is fixedly connected to the outer left side of the fixed ring 8. The outer wall of the fourth toothed ring 21 is meshed with the outer side of the transmission gear 12.

[0022] Specifically, an auxiliary rod 16 is slidably connected to the lower outer wall of the housing 13. A fixed ball 17 is fixedly connected to the lower end of the auxiliary rod 16. The outer wall of the fixed ball 17 is positioned above the movable ball 18, used to press and limit the movable ball 18 when the planetary ball 3 is installed. A limit ring 14 is threadedly connected to the upper side of the housing 13. The outer wall of the limit ring 14 is positioned above the auxiliary rod 16. The vertical position of the auxiliary rod 16 can be adjusted by rotating the limit ring 14. A spring 15 is sleeved on the upper outer wall of the auxiliary rod 16 to provide upward elastic support force, so that the fixed ball 17 maintains pressure on the movable ball 18. A second toothed ring 19 is fixedly connected to the upper outer wall of the auxiliary rod 16. The outer wall of the second toothed ring 19 is positioned above the spring 15, and can cooperate with other transmission components to realize power transmission. A first gear ring 11 is fixedly connected to the lower side of the outer wall of the rotating plate 4. A third adjusting gear 10 is meshed with the outer wall of the right side of the first gear ring 11. The outer wall of the third adjusting gear 10 is rotatably connected to the outer wall of the upper side of the base 2, used to change the transmission direction and speed. A second adjusting gear 9 is meshed with the outer wall of the right side of the third adjusting gear 10. The outer wall of the second adjusting gear 9 is rotatably connected to the outer wall of the upper side of the base 2, further adjusting the speed and direction. A third gear ring 20 is fixedly connected to the outer wall of the left side of the rotating ring 5. The outer wall of the third gear ring 20 is meshed with the outside of the second adjusting gear 9, enabling the rotating ring 5 to obtain revolution power. A second gear ring 19 is fixedly connected to the outer wall of the right side of the rotating ring 5. A first adjusting gear 7 is meshed with the outer wall of the right side of the second gear ring 19. The outer wall of the first adjusting gear 7 is rotatably connected to the upper side of the outer wall of the base 2, used to assist in adjusting the motion state of the rotating ring 5. A fourth gear ring 21 is fixedly connected to the outer wall of the left side of the fixed ring 8. The outer wall of the fourth gear ring 21 is meshed with the outside of the transmission gear 12, providing a power source for the rotation of the planetary sphere 3.

[0023] Working Principle: First, the motor 6 inside the base 2 is activated. The rotating end of the motor 6 drives the rotating plate 4 and the star sphere 1 to rotate. The first toothed ring 11 on the lower side of the outer wall of the rotating plate 4 meshes with the third adjusting gear 10, thereby driving the third adjusting gear 10 and the second adjusting gear 9 meshing with it to rotate. The second adjusting gear 9 meshes with the third toothed ring 20 on the left side of the rotating ring 5, causing the rotating ring 5 to revolve around the star sphere 1, which in turn drives the planet sphere 3 on the rotating ring 5 to revolve synchronously. During the revolution, the fixed ring 8 on the outer side of the rotating ring 5 remains stationary, and the fourth toothed ring 21 on its left side meshes with the transmission gear 12 on the lower side of the planet sphere 3, causing the planet sphere 3 to rotate on its own axis while revolving around the star sphere. The second toothed ring 19 on the right side of the rotating ring 5 meshes with the first adjusting gear 7, and can change the transmission ratio and direction of rotation in conjunction with other adjusting gears. By adjusting the gear ratios, the rotational and revolution speed ratio of the planet sphere 3 can be precisely controlled, achieving a more realistic simulation of solar system operation. When planetary ball 3 needs to be replaced, the limiting ring 14 on the rotating housing 13 moves it downward, causing the auxiliary rod 16 and the fixed ball 17 to descend. The movable ball 18, no longer constrained, slides outward, releasing its fixation on the connecting rod of planetary ball 3, allowing for easy removal of planetary ball 3. During installation, the operation is reversed: the limiting ring 14 moves upward, the spring 15 pushes the auxiliary rod 16 upward, and the fixed ball 17 presses against the movable ball 18, causing it to engage with the connecting rod groove. Simultaneously, the cross groove of the connecting rod engages with the tenon of the transmission gear 12, ensuring normal power transmission.
