Astronomical globe

Abstract

The utility model relates to an astronomical globe which is composed of a geographical pattern ball, a built-in light insulation disc, a built-in light insulation disc fixing shaft and a base. The geography pattern ball is formed by folding two hemispherical shells and is sequentially composed of a lamplight ball shell, a globe map film and a transparent black film from inside to outside, the whole geography pattern ball is almost in a black state due to shielding of the transparent black film layer on the outer layer, and the pattern can be displayed only when the lamp in the built-in light insulation disc is turned on. The single-face light on the built-in light insulation disc is powered on and emits light, half of the geographical pattern ball is illuminated and displayed, and the geographical pattern of the other hemisphere cannot be illuminated due to the shielding of the built-in light insulation disc and is in a black state, so that the day and night scene of the earth is displayed on the tellurion. The angle of 23.5 degrees is formed between the built-in light insulation disc fixing shaft and the geography pattern ball and is consistent with the included angle between the sun revolution axis of the earth and the rotation axis of the earth, so that various astronomical scenes of the earth under the sun illumination can be displayed in real time.

Description

Technical Field

[0001] This invention relates to the field of geography teaching aids, specifically astronomical globes. Background Art

[0002] In primary and secondary school science courses, globes and related knowledge are an important part. Globes effectively demonstrate the geographical distribution on Earth, allowing students to easily and intuitively see various geographical features. To learn this knowledge well, it's best to let students visually observe the day and night cycle on a globe.

[0003] To demonstrate the astronomical phenomena caused by Earth in the universe, teachers have created various teaching aids. Designs depicting Earth's day and night cycles are frequently seen in science competitions such as experimental instrument design and teaching aid design. Some designs are extremely complex, with many additional accessories. While they achieve a certain effect, none offer a groundbreaking improvement. Ordinary globes cannot demonstrate the day and night scenes caused by astronomical factors in the universe, such as the length of day and night in different regions, the changing seasons, and the phenomena of polar day and polar night. Students can only learn this knowledge through imagination, making it difficult to master this content.

[0004] I previously designed and was granted a patent, number 2009101265704, entitled "Globe Displaying Day and Night." This globe performed well in all aspects, but new problems were discovered during use. Due to its complex structure, the inner and outer spheres needed to rotate, but the gap between them couldn't be too large. The rotating inner sphere was difficult to fix properly because the outer sphere was also rotating. Even if it were manufactured, structural issues caused frequent malfunctions during use. Solving this problem would be very costly, thus compromising its practicality. Summary of the Invention

[0005] The purpose of this invention is to provide a globe to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The astronomical globe consists of a sphere with geographic patterns, a built-in light-blocking disk, a fixed shaft for the built-in light-blocking disk, and a base.

[0008] The geographic pattern sphere is composed of two hemispherical shells joined together, consisting of a light-up sphere, a globe map membrane, and a transparent black membrane from the inside out. The transparent black membrane makes the globe appear as a black sphere with the geographic pattern almost hidden. The light-up sphere has mounting holes, centered on the position corresponding to the pole on the globe map membrane (as shown in the figure, the South Pole). Around the mounting holes are rotating gears used to drive the light-up sphere to rotate.

[0009] The built-in light-blocking disc is a circular plate slightly smaller than the inner diameter of the light-emitting sphere. It has lights on both sides, which can illuminate one side or both sides simultaneously. A U-shaped fastener connects to the fixed shaft of the built-in light-blocking disc; the illustration shows a diagram with two fasteners. When the built-in light-blocking disc illuminates only one side, half of the light-emitting sphere is illuminated, displaying the pattern brightly as a daytime hemisphere. The other half remains dark due to the light-blocking disc's obstruction, becoming a nighttime hemisphere. When illuminated from both sides, the entire sphere displays a bright white pattern, allowing it to be used as a regular globe.

[0010] The built-in light-blocking disc fixing shaft is a hollow zigzag tube. The extension lines of the two straight shafts form a 23.5-degree angle. The two straight shafts are used to fix the built-in light-blocking disc and connect to the base, respectively. Wires can be passed through the hollow part. The motor is installed on the top through the motor ring. The driving gear on the motor meshes with the driven gear installed on the straight shaft. There is also a wiring slip ring.

[0011] The base contains a power supply, control switch, motor, and a connecting rod mounted on the motor's rotating shaft. The upper end of the connecting rod is equipped with a drive gear that engages with the rotating gears around the mounting holes of the geographic pattern sphere, which drive the rotating shell of the light sphere to rotate.

[0012] The built-in light-blocking disc is fixed to the upper straight shaft of the built-in light-blocking disc fixing shaft by a U-shaped fixing buckle. An adjusting nut is used to adjust the vertical position of the built-in light-blocking disc, ensuring it is centered on the geographic pattern sphere when finished. The driven gear on the straight shaft connects to the built-in light-blocking disc, allowing the gear's rotation to synchronously drive the disc's rotation. The motor wire on the fixed shaft passes through a hollow channel within the shaft and exits through the lower straight shaft opening, connecting to the power supply and control switch inside the base. The lighting wire on the built-in light-blocking disc, connected via a wiring slip ring, also passes through a hollow channel on the fixed shaft and exits through the lower straight shaft opening, connecting to the power supply and control switch inside the base. With these connections, the built-in light-blocking disc, fixed to the straight shaft on the fixed shaft, aligns with the geographic pattern sphere. The lower straight shaft of the built-in light-blocking disc fixing shaft passes through the mounting hole on the light sphere shell and is fixed to the base. The drive wheel driven by the motor inside the base meshes with the rotating gears around the mounting holes of the geographic pattern ball, so that when the base motor is powered on and rotates, the drive gear can drive the geographic pattern ball to rotate together. The motor wires inside the base are connected to the power supply and control switch inside the base.

[0013] The aforementioned geographic pattern sphere has an outer transparent black film that is directly applied to the globe map film using a black transparent material.

[0014] The inner wall of the aforementioned geographic pattern sphere light is also coated with a black transparent material to reduce reflections on the inner wall.

[0015] The built-in light-blocking disc fixing shaft is designed in a Z-shape to increase strength. As shown in the figure, the upper positioning post extends from the north point of the geographic pattern sphere, and the positioning post and the lower straight axis of the built-in light-blocking disc fixing shaft are on the same straight line.

[0016] The astronomical globe is manually operated, with an internal light-blocking disk rotating through the interaction of internal and external magnets.

[0017] The rotating device inside the astronomical globe has a motor on the fixed shaft of the built-in light-blocking disk that rotates once a year through a gear combination, and a motor in the base that rotates the geographic pattern sphere once a day through a gear combination, so that the astronomical globe can operate synchronously with the earth in real time.

[0018] With the above configuration, when the internal light is not powered, the entire geographic pattern sphere is almost black due to the outer transparent black film layer. When the light inside the built-in light-blocking disk is lit, the pattern appears. When the light on one side is powered on, half of the geographic pattern sphere is illuminated and displayed, while the other half remains black due to the light blocking the internal light-blocking disk. This allows the display of day and night on a globe. Because the fixed axis of the built-in light-blocking disk forms a 23.5-degree angle with the geographic pattern sphere, which coincides with the angle between the Earth's solar orbital axis and the Earth's rotational axis, various astronomical scenes under sunlight can be displayed in real time.

[0019] This invention solves the problem of various astronomical scenes that cannot be displayed on ordinary globes using a simple method, making the globe a popular science instrument that integrates astronomy and geography. It has a simple structure, is easy to operate, and makes up for the deficiency of ordinary globes in showing the lighting scenes in the universe. It is a brand-new globe with greater scientific significance for teaching and popular science. Attached Figure Description

[0026] like Figure 1 As shown, the astronomical globe consists of a geographic pattern sphere 2, an internal light-blocking disk 3, an internal light-blocking disk fixing shaft 4, and a base 1. The geographic pattern sphere 2 is formed by two hemispherical shells joined together, consisting of a light-emitting sphere, a globe map film, and a transparent black film from the inside out. The transparent black film makes the globe appear as a black sphere with the geographic pattern almost hidden. The light-emitting sphere has mounting holes centered on the position corresponding to the pole on the globe map film (as shown in the figure, the South Pole). Rotating gears 21 are placed around the mounting holes to drive the rotation of the light-emitting sphere.

[0027] like Figure 1 , 2 The built-in light-blocking disc 3 shown is a circular plate slightly smaller than the inner diameter of the light bulb shell. Lighting lamps 32 are provided on both sides. The number can be set according to the lighting requirements. The illustration shows a schematic diagram with four lamps connected in parallel. The lighting lamps can illuminate one side or both sides simultaneously. The U-shaped fixing buckle 31 is a movable buckle used to connect with the fixed shaft 4 of the built-in light-blocking disc. The illustration shows a schematic diagram with two buckles.

[0028] like Figure 1 , 3 The built-in light-blocking disc fixing shaft 4 is a hollow zigzag tube. The extension lines of the two straight shafts form a 23.5-degree angle. The two straight shafts are used to fix the built-in light-blocking disc and connect to the base, respectively. Wires can be passed through the hollow part. The motor 43 (with a speed regulating gear box) is installed on the top through the motor ring 44. The motor 43 is connected to the drive gear 45 through the connecting rod 49, which meshes with the driven gear 42 installed on the straight shaft. The connection slip ring 41 is also connected.

[0029] like Figure 1 As shown, the base contains a power supply 13, control switches 14, 15, and 16, a motor 11 (with an internal speed-regulating gearbox), a connecting rod 12 mounted on the rotating shaft of the motor 11, and an active gear with teeth that is fully aligned with the rotating gear 21 that is placed around the mounting hole of the geographic pattern ball 2 to drive the light ball shell to rotate.

[0030] like Figure 1 , 4The built-in light-blocking disc 3 is fixed to the upper straight shaft of the built-in light-blocking disc fixing shaft 4 by a U-shaped fixing buckle 31. The adjusting nut 47 is used to adjust the vertical position of the built-in light-blocking disc 3, so that the built-in light-blocking disc 3 is in the center of the geographic pattern sphere 2 when finished. The driven gear pin 46 on the straight shaft is connected to the built-in light-blocking disc 3, so that the rotation of gears 45 and 42 can synchronously drive the built-in light-blocking disc 3 to rotate. The motor 43 wire on the built-in light-blocking disc fixing shaft 4 passes through the hollow channel inside the shaft 4 and exits from the lower straight shaft opening, connecting to the power supply 13 and control switch 14 in the base 1. The lighting lamp 32 wire on the built-in light-blocking disc 3 is connected to the light-blocking disc fixing shaft 4 by a connecting slip ring 41, also passing through the hollow channel inside the built-in light-blocking disc fixing shaft 4 and exiting from the lower straight shaft opening, connecting to the power supply 13 and control switch 15 in the base 1. 48 in the figure is the lead-out wire. The built-in light-blocking disc 3, which is fixed to the straight shaft on the light-blocking disc fixing shaft 4 and connected in the above way, is aligned with the geographic pattern sphere 2. The lower straight shaft of the built-in light-blocking disc fixing shaft 4 passes through the mounting hole of the light bulb shell and is fixed to the base 1. The drive wheel driven by the motor 11 inside the base meshes with the rotating gear 21 around the mounting hole of the geographic pattern ball 2, so that when the base motor 13 is powered on and rotates, the drive gear can drive the geographic pattern ball 2 to rotate together. The motor 11 wire inside the base 1 is connected to the power supply and control switch 16 inside the base.

[0031] like Figure 1 As shown, as an alternative, the outer transparent black film of the geographic pattern sphere 2 is directly formed by coating the outside of the globe map film with black transparent material; in order to reduce the reflection of the inner wall, the inner wall of the geographic pattern sphere is sprayed with black transparent material.

[0032] like Figure 5 As shown, as an alternative, the built-in light-blocking disc fixing shaft 4 is configured in a Z-shape to increase the stability of the inner shaft. As shown in the figure, the upper positioning post 410 extends from the position of the North Pole of the geographic pattern sphere 2, and the positioning post 410 and the lower straight axis of the built-in light-blocking disc fixing shaft 4 are on the same straight line.

[0033] like Figure 6 As shown, as an alternative, the astronomical globe is made manually, with the internal light-shielding disk rotating through the cooperation of inner and outer magnets 51 and 52. The figure shows an example with the appearance of a regular globe. The base 1 has a Z-shaped fixing bracket 17 for the internal light-shielding disk fixing shaft 4. An inner magnet 51 is positioned on the upper part of the internal light-shielding disk (as shown in the example with two magnets). During use, the outer magnet 52 is held and rotated at the corresponding position above the invention. Due to the interaction of the inner and outer magnetic forces, the inner magnet drives the internal light-shielding disk to rotate along with the outer magnet 52. The lighting lamp 32 (an example with two lamps shown in the figure) has its wires passing through the internal light-shielding disk fixing shaft 4 via a wiring slip ring 41, exiting from the base and connecting to the power supply 13 and control switch 15.

[0034] like Figure 1 As shown, as an alternative, the motor 43 on the fixed shaft 4 of the built-in light-blocking disc makes the built-in light-blocking disc 3 rotate once a year through a gear combination, and the motor 11 in the base 1 makes the geographic pattern sphere rotate once a day through a gear combination, so as to realize the real-time synchronous operation of the astronomical globe and the earth, and make the globe day and night clock.

[0035] Finally, it should be noted that the above examples are merely a few specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and many variations are possible. All variations that can be directly derived or conceived by those skilled in the art from the disclosed content should be considered within the scope of protection of the present invention.
