[0034] The following disclosure provides many different embodiments or examples for implementing different structures of the embodiments of the present utility model. To simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0035] To better understand the purpose, structure, and function of the present utility model, the following further describes in detail an electric drive solar and lunar eclipse demonstration device of the present utility model with reference to the accompanying drawings.

[0036] As Figures 1-8 shown, an electric drive solar and lunar eclipse demonstration device of the present utility model includes a base 1. A rotating mechanism is rotatably installed on the base 1. The support rod of the sun ball 27 penetrates through one end of the rotating mechanism and is fixedly connected to the partition 2 inside the base 1. The rotating mechanism causes the earth 18 to revolve around the sun ball 27.

[0037] Specifically, the rotating mechanism includes a rotating cylinder 5 rotatably connected to the upper side of the base 1. A driven wheel 6 is connected to the lower side of the rotating cylinder 5. The driven wheel 6 is located inside the base 1. A driving wheel 4 is rotatably arranged on the partition 2. After being driven by a motor 3, the driving wheel 4 meshes with the driven wheel 6. Since a long plate 7 is connected to one side of the rotating cylinder 5 and the earth 18 is located on the long plate 7 at the end far from the rotating cylinder 5, when the driven wheel 6 rotates, the rotating cylinder 5 drives the long plate 7 and the earth 18 at the upper end to revolve around the sun ball 27.

[0038] And an orbit 24 is installed at the other end of the rotating mechanism. The upper side of the orbit 24 has an inclined section for simulating the lunar orbit inclination. A self-rotating mechanism is installed on the rotating mechanism inside the orbit 24. The upper end of the self-rotating mechanism is installed with the earth 18. And a lunar component is connected to one side of the self-rotating mechanism. The lunar component is located above the orbit 24. When the rotating mechanism rotates, it causes the earth 18 to rotate around the sun ball 27, and at the same time drives the self-rotating mechanism to operate, so that while the earth 18 rotates, the lunar component rotates around the earth 18.

[0039] To enable the lunar component and the earth 18 to rotate, a second hollow tube 25 is arranged inside the rotating cylinder 5. The lower end of the second hollow tube 25 penetrates through the rotating cylinder 5 and is fixedly connected to the partition 2. The rotating cylinder 5 can rotate outside the second hollow tube 25. The upper end of the second hollow tube 25 is connected with a gear ring 26. The support rod of the sun ball 27 penetrates through the second hollow tube 25 and is fixedly connected to the partition 2. The sun ball 27 remains stationary during the demonstration.

[0040] On the upper side of the long board 7, there are symmetric fixed seats. A rotating rod 8 is rotatably arranged on the fixed seats. Two ends of the rotating rod 8 are respectively connected with a first gear 9 and a second gear 91. The first gear 9 meshes with the gear ring 26. The self-rotation mechanism includes a first hollow tube 10 rotatably connected with the long board 7. Two ends of the first hollow tube 10 are respectively connected with a fourth gear 12 and a third gear 11. The third gear 11 meshes with the second gear 91. Therefore, when the rotating cylinder 5 rotates, the first gear 9 located on the upper side of the long board 7 meshes with the gear ring 26, and then the second gear 91 meshes with the third gear 11 on the lower side of the first hollow tube 10, causing the first hollow tube 10 to rotate. When the first hollow tube 10 rotates, the fourth gear 12 rotates accordingly.

[0041] Since a positioning rod 13 is arranged inside the first hollow tube 10, the positioning rod 13 penetrates through the first hollow tube 10 and is fixedly connected with the long board 7. An installation plate 14 is connected to the upper end of the positioning rod 13. A globe 18 is rotatably arranged on the upper side of the installation plate 14. Since a upper gear 15 is rotatably arranged at the bottom of the installation plate 14, a lower gear 16 is connected to the lower end of the upper gear 15. The lower gear 16 meshes with the fourth gear 12. A fifth gear 17 is connected to the rotating shaft of the globe 18. The fifth gear 17 meshes with the upper gear 15. Therefore, when the first hollow tube 10 rotates, through the meshing of the fourth gear 12 and the lower gear 16, the upper gear 15 is driven to rotate. After the upper gear 15 meshes with the fifth gear 17, the fifth gear 17 causes the globe 18 to rotate self.

[0042] Furthermore, the moon assembly includes a connecting rod 19 connected to the upper end of the first hollow tube 10. The connecting rod 19 is connected with a vertical rod 20. The upper end of the vertical rod 20 is installed with a moon 21. While the first hollow tube 10 rotates, the connecting rod 19 drives the vertical rod 20 to rotate, causing the moon 21 to rotate around the globe 18.

[0043] In order to simulate the lunar orbit inclination, a moving sleeve 23 is slidably connected to the lower end of the vertical rod 20. The bottom of the moving sleeve 23 is of an arc structure. A spring 22 is sleeved on the vertical rod 20 on the upper side of the moving sleeve 23. Two ends of the spring 22 are respectively connected with the vertical rod 20 and the moving sleeve 23. When the moon 21 moves to the higher end of the orbit 24, the moving sleeve 23 slides upward to squeeze the spring 22. When the moon 21 moves to the lower end of the orbit 24, the spring 22 causes the moving sleeve 23 to slide downward to fit with the upper side of the orbit 24.

[0044] Working principle of an electric-driven solar and lunar eclipse demonstration device: During the demonstration, start the motor 3. The motor 3 drives the driving wheel 4 and the driven wheel 6 to engage, causing the rotating cylinder 5 to drive the long board 7 to rotate. As a result, the Earth 18 revolves around the sun ball 27. While the long board 7 is rotating, the first gear 9 engages with the gear ring 26, and the second gear 91 and the third gear 11 engage, causing the first hollow tube 10 to rotate. At this time, the first hollow tube 10 drives the connecting rod 19 to rotate, realizing the rotation of the moon 21 around the Earth 18. At the same time, the fourth gear 12 at the upper end of the first hollow tube 10 engages with the lower gear 16 on the mounting plate 14, prompting the upper gear 15 and the fifth gear 17 to engage, causing the Earth 18 to rotate on its own axis.

[0045] It can be understood that the present utility model is described through some embodiments. As is known to those skilled in the art, without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
