Description

Technical Field

[0001] This utility model relates to the field of globe technology, specifically to a globe that can display the terminator and the point of direct sunlight. Background Technology

[0002] A globe is a model of the Earth. While it cannot fully reflect the actual state of the Earth, it can help us clarify many related concepts and gain a basic understanding of the Earth. However, most globes currently lack good interactivity. Users can only learn about geographical information such as the shape of the Earth and the distribution of continental and oceanic plates by rotating the globe. Geographical phenomena such as the terminator and the point where the sun's rays are directly overhead, which change with the months, are not intuitively displayed. These geographical phenomena affect the Earth's seasons, day and night, and changes in day and night length. As a result, users cannot intuitively understand the fundamental reasons for these phenomena in daily life. As an important tool for users in the learning stage to acquire knowledge about Earth's geography, the above-mentioned shortcomings result in learners having a poor effect on obtaining geographical information about the Earth from globes.

[0003] Chinese patent CN220065030U discloses a globe, specifically relating to the field of globe technology. It includes a support frame with a connecting component at the top, and a globe body at the top of the connecting component. The globe body comprises a sphere, a mounting frame, and two rotating shafts. The ends of the two rotating shafts facing each other are fixedly connected to the sphere, while the ends facing away from each other are movably connected to the mounting frame via bearings. An adjustment component is located inside the support frame. The globe adjusts its height by moving the mounting frame, causing the sphere to move synchronously. This allows learners, such as students, to view the globe from a distance. However, the globe's surface features a world map with country names, latitude and longitude lines, and complex borders. Adjusting the globe's height only allows learners at a distance to see the globe itself, but it does not directly demonstrate the geographical phenomena of the terminator and the changing sun's direct rays throughout the month. Therefore, there is still room for improvement. Utility Model Content

[0004] To address the technical deficiencies in the background technology, this utility model proposes a globe capable of displaying the terminator and the subsolar point, thus solving the aforementioned technical problems and meeting practical needs. The specific technical solution is as follows:

[0005] A globe capable of displaying the terminator and the point of direct sunlight includes a globe sphere, a sphere support, and a terminator indicator ring. The globe sphere has a through hole that passes through its diameter line, and a rotating shaft passes through the through hole. The sphere support is fixedly connected to both ends of the rotating shaft.

[0006] The globe sphere is fitted with a terminator ring, which is at the same center as the globe sphere. The terminator ring is provided with several connecting rods that extend to the globe support, and the ends of the connecting rods are provided with adjusting sliders.

[0007] The surface of the spherical support is provided with an adjustment groove that matches the adjustment slider, and the adjustment slider is located in the adjustment groove;

[0008] The adjusting groove is equipped with a direct-spot slider, which is located on the vertical line of the center of the terminator ring. The direct-spot slider is fixedly connected to the terminator ring via a connecting rod.

[0009] As a further technical solution of this utility model, the surface of the spherical support is provided with a month scale, which is located at the intersection of the direct-shooting slider and the adjustment groove.

[0010] As a further technical solution of this utility model, the outer surface of the globe is made of ferromagnetic material, and the outer surface of the globe is provided with a number of land plates and a number of ocean plates. The back sides of the land plates and ocean plates are magnetically attracted to the outer surface of the globe.

[0011] As a further technical solution of this utility model, the landmass consists of 7 pieces, and the shapes of the 7 landmasses respectively match those of Asia, Africa, North America, South America, Antarctica, Europe, and Oceania on Earth.

[0012] As a further technical solution of this utility model, the outer surface of the land plate is provided with a plurality of national plates, and the back of the national plates has a magnetism that attracts each other to the outer surface of the land plate.

[0013] As a further technical solution of this utility model, the ocean plate is provided in four parts, and the shapes of the four ocean plates respectively match the Pacific Ocean, Atlantic Ocean, Indian Ocean and Arctic Ocean of the Earth.

[0014] As a further technical solution of this utility model, the bottom of the ball support is provided with a support base, and a handle is provided between the ball support and the support base.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention simulates the changes in the terminator line during Earth's rotation by rotating the globe sphere to change its relative position with the terminator ring. The tilt angle of the terminator ring can be adjusted by changing the slider, while simultaneously moving the direct sunlight slider between the Tropic of Cancer and the Tropic of Capricorn. This allows observation of the change in the terminator tilt angle as the sun's direct point changes, thus revealing the principles behind phenomena such as changes in day and night length and the polar regions of polar day and night. Furthermore, by observing the relative position of the month scale and the direct sunlight slider, users can observe the changes in the terminator line and the sun's direct point as the months change, enabling them to learn more about Earth's geography from the globe.

Detailed Implementation

[0020] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0021] like Figure 1 , 2As shown, a globe capable of displaying the terminator and the point of direct sunlight includes a globe sphere 1, a globe support 2, and a terminator indicator ring 3. The globe sphere 1 has a through hole extending through its diameter, and a rotating shaft 21 passes through the through hole. The globe support 2 is fixedly connected to both ends of the rotating shaft 21. A support base 24 is provided at the bottom of the globe support 2, and a handle 25 is provided between the globe support 2 and the support base 24. The globe sphere 1 is covered by a terminator indicator ring 3, which has the same center as the globe sphere 1. The terminator indicator ring 3 has several connecting rods 31 extending to the globe support 2, and adjusting sliders 32 are provided at the ends of the connecting rods 31. The surface of the globe support 2 has an adjusting groove 22 that matches the adjusting slider 32, and the adjusting slider 32 is located within the adjusting groove 22. A direct sunlight slider 4 is provided within the adjusting groove 22, located on the vertical line perpendicular to the center of the terminator indicator ring 3, and the direct sunlight slider 4 is fixedly connected to the terminator indicator ring 3 via the connecting rods 31.

[0022] The globe sphere 1 has a world map depicted on its surface, featuring lines of latitude and longitude, the Tropic of Cancer and Tropic of Capricorn, the equator, and other markings. This allows users to gain a deeper understanding of the Earth's structure. Latitude and longitude lines indicate countries or regions at the same latitude. Based on common knowledge, some regions on Earth share similar climate characteristics due to their similar latitudes. Therefore, by combining the latitude lines on the globe with certain obvious climate features, users can identify the specific climate characteristics of a particular latitude. The globe sphere 1 has a through-hole that connects to the North and South Poles on the world map. This through-hole allows the globe sphere 1 to rotate around a pivot 21, simulating the Earth's rotation. Rotating the globe sphere 1 also allows users to observe it from multiple angles. The support base 24 ensures the globe is placed stably on a table or similar surface for easy use. The handle 25 allows users to hold the globe and lift it to adjust the viewing angle as needed.

[0023] The terminator ring 3 of this invention is used to simulate the Earth's terminator. The terminator ring 3 divides the globe sphere 1 into two hemispheres, designated as the day hemisphere and night hemisphere respectively. Users can rotate the globe sphere 1 according to the direction of Earth's rotation, changing the relative position of its surface with the terminator ring 3, thus simulating the change of the terminator line during Earth's rotation. Based on the designated day and night hemispheres, users can understand the principles of day and night alternation, sunrise and sunset. The terminator ring 3 is connected to two adjusting sliders 32 via at least two connecting rods 31. The adjusting sliders 32 can slide along adjusting grooves 22. When the adjusting slider 32 slides in the adjusting groove 22, the tilt angle of the terminator ring 3 will change. There is a notch at the intersection of the terminator ring 3 and the sphere support 2 to prevent the terminator ring 3 from being blocked by the sphere support 2 when the tilt angle changes. By adjusting the tilt angle of the terminator ring 3, the change of the terminator tilt angle when the sun's direct point on the Earth's surface changes is simulated. At the same time, the globe sphere 1 is rotated according to the direction of the Earth's rotation. The change of the relative position between the world map on the surface of the globe sphere 1 and the terminator ring 3 can be observed to understand the principle of the change of day and night length and the occurrence of polar day and polar night at the North and South Poles.

[0024] The direct-sun slider 4 of this invention can serve as a reference point for simulating the direct point of sunlight. The direct-sun slider 4 can slide along the adjusting groove 22. During the sliding process, the tilt angle of the terminator ring 3 is adjusted by the connecting rod 31. The direct-sun slider 4 can slide between the Tropic of Cancer and the Tropic of Capricorn, thereby simulating the phenomenon of the direct point of sunlight moving between the Tropic of Cancer and the Tropic of Capricorn on the Earth's surface during the Earth's revolution. By rotating the globe sphere 1 and using the terminator ring 3 as a reference, the principle of the changes in day and night length and the occurrence of polar day and polar night at the North and South Poles can be understood more intuitively. At this time, the side of the globe sphere 1 closer to the direct-sun slider 4 is the day hemisphere. Users can more intuitively understand the changes in the Earth's day hemisphere and night hemisphere when the direct point of sunlight is in different positions. At the same time, they can more intuitively understand the principle of the day and night length phenomenon at their own location when the direct point of sunlight is in different positions, and infer the position of the direct point of sunlight based on the day and night length phenomenon at their own location.

[0025] like Figure 1As shown, in one of the preferred embodiments of this utility model, the surface of the sphere support 2 is provided with a month scale 23, which is located at the intersection of the direct sunlight slider 4 and the adjustment groove 22. The month scale 23 marks the months 1 to 12 with 12 scales, and the position of the corresponding month scale matches the latitude position of the direct sunlight slider 4. When the direct sunlight slider 4 is slid to adjust the sun's direct point, the month corresponding to the current direct point can be known. This connects information such as the terminator, the sun's direct point, and the month, allowing for a more macroscopic observation of the changes in the Earth at different times. The changes in the terminator and the sun's direct point during the month change can be observed, and the reasons for the changes in the four seasons can be deduced. Users can learn more about the Earth's geographical information from the globe.

[0026] like Figure 2 As shown, in one of the preferred embodiments of this utility model, the outer surface of the globe sphere 1 is made of ferromagnetic material. The outer surface of the globe sphere 1 is provided with several land plates 11 and several ocean plates 12. The back sides of the land plates 11 and ocean plates 12 are magnetically attracted to the outer surface of the globe sphere 1. The main structure of the globe sphere 1 of this utility model is a magnetic mesh woven from ferromagnetic materials such as iron, so that the globe sphere 1 forms a hollow sphere. The back sides of the land plates 11 and ocean plates 12 are provided with flexible magnets that can be bent. The land plates 11 and ocean plates 12 are curved and have an arc that matches the outer surface of the globe sphere 1. The land plates 11 and ocean plates 12 can be attracted to the outer surface of the globe sphere 1 by the mutual attraction between the flexible magnets on their back sides and the magnetic mesh, thereby making the globe sphere 1 a sphere that simulates the Earth.

[0027] There are seven landmasses 11, each with a shape corresponding to Asia, Africa, North America, South America, Antarctica, Europe, and Oceania. The outer surface of each landmass 11 has several national plates 111, whose backs are magnetically attracted to the outer surface of the landmasses 11. The outlines of the seven landmasses 11 correspond to Asia, Africa, North America, South America, Antarctica, Europe, and Oceania, respectively. Each landmass 11 is marked with the name of its corresponding continent, and the outlines of the countries within that continent are depicted on its surface. The landmasses 11 clearly depict the borders of adjacent countries and label each country's name. Users can use the globe to more intuitively understand the geographical locations of the continents and countries on Earth.

[0028] Furthermore, a metal iron or flexible magnet can be installed on the back of the national plate 111, allowing the national plate 111 to be magnetically attached to the outer surface of the land plate 11. The edge contour of the national plate 111 matches the shape of the corresponding country's territory. The national plate 111 can be made according to the country with a large land area, thus forming several national plates 111 of different shapes. Countries with smaller land areas are not made into national plates 111 to avoid loss. The national plates 111 of smaller countries are integrally formed with the land plate according to their land shape. By assembling the national plates 111 of the corresponding countries into the land plate 11 of the corresponding continent, a complete land continent map is formed. The national plate 111 is fixed to the land plate 11 by magnetism. Since the edge contour of the national plate 111 matches the shape of the corresponding country's territory, the national plate 111 can intuitively display the geographical information such as the shape of the corresponding country's territory and the borders of neighboring countries to the user. The user can efficiently obtain the above geographical information during the process of assembling or disassembling the national plate 111.

[0029] Furthermore, the thickness of the landmass 11 can be adaptively adjusted according to the land elevation of different regions on Earth, so that the surface of the landmass 11 can simulate the real landforms of the Earth and present uneven terrain. The landmass features such as plains, hills, mountains, plateaus, and basins of the Earth can be presented in the landmass 11, and different colors can be filled according to different landform features to make the corresponding landform features more realistic and obvious. The globe can more realistically display the landforms of different regions of the Earth to users, and users can obtain geographical information about the landforms of different regions of the Earth through the globe.

[0030] With the above structure, it should be further explained that there are four oceanic plates 12, the shapes of which correspond to the Pacific, Atlantic, Indian, and Arctic Oceans of the Earth, respectively; the outlines of the four oceanic plates also correspond to the Pacific, Atlantic, Indian, and Arctic Oceans of the Earth, respectively, and each oceanic plate 12 is labeled with the name of the corresponding ocean. By assembling the seven land plates 11 and the four oceanic plates 12 on the surface of the globe sphere 1, a complete world map is formed. The boundaries between the land plates 11 and the oceanic plates 12 serve as the boundaries between the continents and oceans on the world map. Since both the landmass 11 and oceanic plates 12 are magnetically attached to the surface of the globe sphere 1, users can easily disassemble the world map and reassemble it using the magnetic properties of the soft magnets. During the disassembly and reassembly process, users can manually interact with the globe. Because the edge contours of the landmass 11 and oceanic plates 12 match the shapes of the seven continents and four oceans on Earth, the landmass 11 and oceanic plates 12 can intuitively display geographical information such as the boundaries of continents and oceans to users. Users can efficiently obtain this geographical information during the manual interaction process.

[0031] Furthermore, the surface of the globe sphere 1 is provided with contour lines that match the edge contours of each land plate 11 and each ocean plate 12. Users can attach the corresponding land plate 11 or ocean plate 12 to the surface of the globe sphere 1 according to the contour lines, avoiding the difficulty of subsequent plate assembly caused by the incorrect position of the land plate 11 or ocean plate 12 when the world map is first assembled. Users can more easily assemble the land plate 11 and ocean plate 12 into a world map.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
