Description

TECHNICAL FIELD

[0001] The utility model relates to the field of toys, especially to a globe. BACKGROUND

[0002] The globe is a model of the earth, which is made by copying the shape of the earth and reducing it according to a certain proportion, and is provided with deformation of length, area, direction and shape. Therefore, the observation of the mutual relationship of various scenes from the globe is overall and approximately correct. At present, the globe has been widely used in teaching and many fields. However, in the prior art, the globe only displays the teaching of the earth's condition by showing the distribution of land and sea on the earth's surface, and other information related to the earth also needs to be displayed by other teaching devices. For example, a globe is disclosed in the patent document with publication number CN213751652U, which displays the distribution of land and sea and the world pattern on the surface of the sphere, and can also demonstrate the rotation of the earth, but cannot realize other teaching display contents.

[0003] Therefore, the applicant of the present case has previously submitted a Chinese utility model application with application number "2023233326251", which provides a new type of globe. In addition to presenting the geographical features of the earth on the surface, the first and second hemispheres can be opened to expand other play methods through the internal space. Thus, the globe has more play methods. In the application, it is pointed out that the geographical features of the southern and northern hemispheres printed on the surface of the first and second hemispheres will be misaligned due to the free rotation of the first and second hemispheres in the open state. In order to ensure the correct connection of the geographical features of the southern and northern hemispheres in the closed state, a positioning structure needs to be provided on the first and second hemispheres, which can uniquely correspond to the first and second hemispheres in the circumferential direction. However, this scheme requires circumferential alignment when closing the first and second hemispheres, which is troublesome, and may also cause misalignment of the first and second hemispheres. SUMMARY

[0004] In order to solve the above problems, the purpose of the present utility model is to provide a globe which, in addition to presenting the geographical features of the earth on the surface, can also open the first and second hemispheres to expand other play methods through the internal space, thereby making the globe have more play methods. Furthermore, a linkage assembly is used to connect the second hemisphere with the first hemisphere, thereby avoiding the circumferential misalignment of the second hemisphere and the first hemisphere.

[0005] In order to achieve the above-mentioned purposes, the utility model adopts the following technical solutions:

[0006] A globe comprises a bracket and a sphere rotatably mounted on the bracket; the sphere comprises a first hemisphere and a second hemisphere with geographical markings of the northern and southern hemispheres arranged on their outer surfaces respectively; the characterised in that the bracket comprises a base and a movable frame pivotally connected to the base; the south pole of the first hemisphere is rotatably mounted on the base of the bracket, and the north pole of the second hemisphere is rotatably mounted on the movable frame of the bracket; the second hemisphere is connected to the first hemisphere by a linkage assembly; when the movable frame rotates relative to the base, the second hemisphere is driven to open and close relative to the first hemisphere; when the second hemisphere covers the first hemisphere, the rotating axes of the first hemisphere and the second hemisphere are on the same axis and can be combined into a complete sphere and rotate synchronously relative to the bracket; when the second hemisphere is opened relative to the first hemisphere, the first hemisphere and the second hemisphere are connected by a linkage assembly and are circumferentially locked to the bracket.

[0007] The present invention adopts the above-mentioned technical solution, which relates to a globe that is divided into two hemispheres, namely a first hemisphere and a second hemisphere, and then has geographical markings of the northern and southern hemispheres printed on their surfaces. Furthermore, the south pole of the first hemisphere is rotatably mounted on a base of a bracket, while the north pole of the second hemisphere is rotatably mounted on a movable bracket of the bracket. Since the movable bracket is pivotally connected to the base, it can drive the second hemisphere to open and close relative to the first hemisphere. Furthermore, to avoid circumferential misalignment between the second hemisphere and the first hemisphere, the present invention utilizes a linkage assembly to connect the second hemisphere to the first hemisphere. This allows for synchronous rotation only when the second hemisphere is closed over the first hemisphere, as the rotation axes of the first and second hemispheres are aligned. However, when the first and second hemispheres are opened to any angle, they become locked and unable to rotate, as their rotation axes are not aligned.

[0008] Based on this, in addition to displaying the Earth's geographical markings on its surface, the globe can also be opened up to expand other ways of playing through the internal space, thus providing more ways to play with the globe. Furthermore, a linkage component is used to connect the second hemisphere to the first hemisphere, thus preventing circumferential misalignment between the second and first hemispheres.

[0009] In a specific embodiment, the linkage assembly includes a sliding member, one end of which is fixed within the first or second hemisphere, and the other end of which is slidably disposed within the second or first hemisphere. When the second hemisphere is capable of opening and closing relative to the first hemisphere, the sliding path of the sliding member is centered about the pivot point of the movable frame. In this embodiment, the sliding member is connected to the second and first hemispheres at both ends, with one end fixed and the other end slidingly connected. This allows the second hemisphere to open and close relative to the first hemisphere, and the sliding member also slides with it. Furthermore, the sliding path of the sliding member is required to be arc-shaped, centered about the pivot point of the movable frame. This allows the second hemisphere and the sliding member to flip concentrically without interfering.

[0010] In a further embodiment, the linkage assembly further includes a sleeve, which is fixedly attached to the second hemisphere or the first hemisphere, with the other end of the slider slidingly disposed within the sleeve; during the opening and closing of the second hemisphere relative to the first hemisphere, the slider slides relative to the sleeve. This embodiment utilizes a combination of the slider and the sleeve to form a linkage assembly. The sliding engagement structure of the slider and the sleeve can be as follows: a sliding groove is constructed on the sidewall of one of the slider and the sleeve, centered at the pivot point of the movable frame, and a sliding post is provided on the other. The sliding post is embedded in the sliding groove and moves along the groove, thereby regulating the movement path of the slider relative to the sleeve.

[0011] In the above scheme, since the second hemisphere is connected to the first hemisphere by a linkage assembly, the second hemisphere can rotate freely when the second hemisphere and the first hemisphere are combined to form a sphere. After the linkage assembly rotates with the sphere, the second hemisphere can only be opened and closed relative to the first hemisphere when the sliding path of the sliding member in the linkage assembly is exactly centered on the pivot point of the movable frame. This is the opening and closing unlocking position. Therefore, in a specific scheme, a feedback component for feedback of the opening and closing unlocking position is constructed at the rotation point of the first hemisphere and the base, and / or the rotation point of the second hemisphere and the movable frame. This can conveniently inform and feedback to the child that the current state can open the globe. The feedback component can be an in-position mark for naked eye observation, or it can be an elastic pin positioning structure that can achieve micro-positioning.

[0012] In a specific embodiment, the base includes a fixed frame, and the movable frame is connected to the fixed frame via a pivot axis; the fixed frame and the movable frame are combined to form an arc-shaped bracket, and the pivot axis is arranged beside the equator of the sphere.

[0013] Preferably, a teaching platform is constructed in the first hemisphere and / or the second hemisphere; the teaching platform constructed in the first hemisphere and / or the second hemisphere is provided with one or more of a geocentric model, a geographical model, a space model, and a climate model.

[0014] In a specific embodiment, the geocentric model is arranged on the first hemisphere, and the upper end of the geocentric model protrudes from the first hemisphere; the second hemisphere is configured as a hemispherical cover; when the first hemisphere and the second hemisphere are combined into a complete sphere, the upper end of the geocentric model is received inside the cover cavity of the second hemisphere. In this scheme, the geocentric model is arranged on the first hemisphere and can rotate with the first hemisphere; the geocentric model is configured as a D-shaped solid, and the upper end of the model protrudes from the first hemisphere, so that more teaching content can be arranged on the geocentric model, especially when the internal structure of the geocenter is configured, the arrangement can be simulated according to the actual situation of the geocenter, which is more consistent with the teaching content and easier to understand. Further, the second hemisphere is configured as a hemispherical cover for opening or covering the geocentric model.

[0015] In a specific embodiment, the geocentric model includes a base part fixedly arranged in the first hemisphere, and a geological circle layer module and / or a magma cave module detachably embedded on the base part;

[0016] The geological circle layer module includes a first sector exposed to the base part, and a stepped body embedded in the base part; the first sector has different geological circle layers constructed on the side wall thereof along the sector surface from inside to outside, and the stepped body has fossil reliefs or biological illustrations of different ages presented on the stepped surface in stages. In this scheme, the first sector of the geological circle layer module can present the geological circle layers on the sector surface, which is more intuitive to reflect the stratum distribution.

[0017] The magma cave module includes a second sector exposed to the base part, and a geological phenomenon imitation embedded in the base part; the geological phenomenon imitation can be an imitation of phenomena such as stalactite. The second sector has a magma flow diagram constructed on the side wall thereof along the sector surface from inside to outside, which can facilitate children to understand the magma distribution in the stratum.

[0018] In addition, the support and / or the inside of the sphere are provided with a voice teaching system, and the inside of the geocentric model and / or the support are provided with a plurality of keys and / or recognition ends for triggering voice teaching by pressing or recognition.

[0019] Further, the voice teaching system can also be networked and expanded, such as updating or playing cloud content in real time.

[0037] like Figures 1 to 8 As shown, this embodiment relates to a globe, comprising a support and a sphere rotatably mounted on the support. The sphere comprises a first hemisphere 21 and a second hemisphere 22, each with geographic markings of the northern and southern hemispheres arranged on its outer surfaces. The support comprises a base 11 and a movable frame 12 pivotally connected to the base 11. In a specific embodiment, the base 11 includes a fixed frame 14, and the movable frame 12 is connected to the fixed frame 14 via a pivot axis 13. The fixed frame 14 and the movable frame 12 together form an arc-shaped support, and the pivot axis 13 is arranged near the equator of the sphere.

[0038] The south pole of the first hemisphere 21 is rotatably mounted on the base 11 of the bracket, and the north pole of the second hemisphere 22 is rotatably mounted on the movable frame 12 of the bracket. The second hemisphere 22 is connected to the first hemisphere 21 by a linkage assembly 4. When the movable frame 12 rotates relative to the base 11, it drives the second hemisphere 22 to open and close relative to the first hemisphere 21. When the second hemisphere 22 covers the first hemisphere 21, the rotation axes of the first hemisphere 21 and the second hemisphere 22 are on the same axis and can be combined into a complete sphere and rotate synchronously relative to the bracket. When the second hemisphere 22 is opened relative to the first hemisphere 21, the first hemisphere 21 and the second hemisphere 22 are connected by the linkage assembly 4 and are circumferentially locked with the bracket.

[0039] This globe is divided into two hemispheres, a first hemisphere and a second hemisphere, and then printed with geographical markings for the northern and southern hemispheres. The south pole of the first hemisphere 21 is pivotally mounted on the base 11 of the support, while the north pole of the second hemisphere 22 is pivotally mounted on the movable frame 12 of the support. Because the movable frame 12 is pivotally connected to the base 11, it can drive the second hemisphere 22 to open and close relative to the first hemisphere 21. To avoid circumferential misalignment between the second hemisphere 22 and the first hemisphere 21, this solution uses a linkage assembly 4 to connect the second hemisphere 22 to the first hemisphere 21. This allows for synchronous rotation only when the second hemisphere 22 is closed over the first hemisphere 21, as the rotation axes of the first and second hemispheres 21 and 22 are aligned. However, when the first and second hemispheres 21 and 22 are opened to any angle, they become locked and unable to rotate because their rotation axes are not aligned.

[0040] Based on this, in addition to displaying the Earth's geographical markings on its surface, the globe can also be opened up to expand other ways of playing through the internal space, thereby providing more ways to play with the globe. Furthermore, the second hemisphere 22 is connected to the first hemisphere 21 using a linkage assembly 4, thereby preventing circumferential misalignment between the second hemisphere 22 and the first hemisphere 21.

[0041] exist Figure 2-4 In the specific embodiments shown in Figures 7 and 8, the linkage assembly 4 includes a sliding member 41. One end of the sliding member 41 is fixed within the first hemisphere 21 or the second hemisphere 22, while the other end of the sliding member 41 slides within the second hemisphere 22 or the first hemisphere 21. When the second hemisphere 22 is able to open and close relative to the first hemisphere 21, the sliding path of the sliding member 41 is centered around the pivot point of the movable frame 12. In this embodiment, the two ends of the sliding member 41 connect the second hemisphere 22 and the first hemisphere 21, respectively, with one end fixed and the other end slidingly connected. This allows the second hemisphere 22 to open and close relative to the first hemisphere 21, and the sliding member 41 also slides with it. Furthermore, the sliding path of the sliding member 41 is required to be an arc-shaped circle, centered around the pivot point of the movable frame 12. This allows the second hemisphere 22 and the sliding member 41 to rotate concentrically without interfering. The sliding member 41 can be directly slidably arranged on the first hemisphere 21 or the second hemisphere 22. Figure 7 and 8 In the further embodiment shown, the linkage assembly 4 further includes a sleeve 42, which is fixedly connected to the second hemisphere 22 or the first hemisphere 21, and the other end of the sliding member 41 is slidably arranged inside the sleeve 42. During the opening and closing process of the second hemisphere 22 relative to the first hemisphere 21, the sliding member 41 slides relative to the sleeve 42. This embodiment adopts a sliding member 41 and a sleeve 42 to form a linkage assembly 4. The sliding matching structure of the sliding member 41 and the sleeve 42 can be adopted as follows: in the sliding member 41 and the sleeve 42, a sliding groove 43 with the pivot point of the movable frame 12 as the center is constructed on the side wall of one of them, and a sliding column 44 is provided on the other. Based on the sliding column 44 being embedded in the sliding groove 43 and moving along the sliding groove 43, the movement path of the sliding member 41 relative to the sleeve 42 can be standardized.

[0042] In the above scheme, since the second hemisphere 22 is connected to the first hemisphere 21 by the linkage assembly 4, the second hemisphere 22 and the first hemisphere 21 can rotate freely when they are combined to form a sphere. After the linkage assembly 4 rotates with the sphere, the second hemisphere 22 can only be opened and closed relative to the first hemisphere 21 when the sliding path of the sliding member 41 in the linkage assembly 4 is exactly centered on the pivot point of the movable frame 12. This is the unlocked position. Therefore, in a specific scheme, a feedback component for feedback of the unlocked position is constructed at the rotation point of the first hemisphere 21 and the base 11, and / or the rotation point of the second hemisphere 22 and the movable frame 12. This can conveniently inform and feedback to the child that the current state of the globe can be opened. The feedback component can be an in-position mark for naked eye observation, or it can be an elastic pin positioning structure that can achieve micro-positioning.

[0043] like Figure 1-4As shown, a teaching platform is constructed in the first hemisphere 21 and / or the second hemisphere 22. The teaching platform constructed in the first hemisphere 21 and / or the second hemisphere 22 is provided with one or more of the geocentric model 3, geographic model, space model, and climate model.

[0044] In a specific implementation scheme, the geocentric model 3 is arranged on the first hemisphere 21, and the upper end of the geocentric model 3 protrudes from the first hemisphere 21. The second hemisphere 22 is constructed as a hemispherical cover. When the first hemisphere 21 and the second hemisphere 22 are combined into a complete sphere, the upper end of the geocentric model 3 is received inside the cover cavity of the second hemisphere 22. In this solution, the geocentric model is arranged on the first hemisphere and can rotate with the first hemisphere. The geocentric model is constructed as a 3D three-dimensional shape, and the upper end of the model protrudes from the first hemisphere. In this way, more teaching content can be set on the geocentric model 3, especially when constructing the internal structure of the center of the earth, the layout can be simulated according to the actual situation of the center of the earth, which is more in line with the teaching content and easier to understand. Furthermore, the second hemisphere is constructed as a hemispherical cover for opening or covering the geocentric model.

[0045] In a specific embodiment, the geocentric model 3 includes a base portion 31 fixedly disposed within the first hemisphere 21, and a geological layer module 32 and / or a magma cave module 33 removably embedded in the base portion 31. A translucent sphere 34 is disposed at the center of the geocentric model 3, and a light source lamp is disposed within the translucent sphere 34. Light emitted by the light source lamp emanates from the translucent sphere 34 to simulate the center of the Earth and also illuminates teaching content displayed on the adjacent geocentric model.

[0046] like Figure 5 As shown, the geological layer module 32 includes a first sector 321 exposed from the base 31 and a step 322 embedded within the base 31. Different geological layers are constructed along the sidewalls of the first sector 321 along its sector-shaped surface from the inside out. Fossil reliefs or biological illustrations from different ages are presented on the step surfaces of the step 322. In this solution, the first sector 321 of the geological layer module 32 can use its sector-shaped surface to present the geological layers, providing a more intuitive representation of the stratum distribution.

[0047] like Figure 6 As shown, the magma cave module 33 includes a second sector 331 exposed from the base 31 and a geological phenomenon simulation 332 embedded within the base 31. The geological phenomenon simulation 332 can be a replica of a phenomenon such as a stalactite. A magma flow diagram is constructed along the sidewall of the second sector 331 from the inside out along its sector-shaped surface. This diagram helps children understand the distribution of magma within the stratum.

[0048] like Figure 4 As shown, the base portion 31 is provided with a notch 312, and the step body 322 of the geosphere layer module 32 and the geological phenomenon imitation piece 332 of the magma cave module 33 are embedded in the mounting groove 312.

[0049] In addition, the inside of the support and / or the sphere is provided with a voice teaching system, and a plurality of buttons 100 and / or recognition ends are constructed inside the earth model 3 and / or on the support, for triggering the voice teaching by pressing or recognition. The voice teaching system can include a control unit, a storage unit and a voice playing module (such as a loudspeaker), and the playing instruction is obtained by pressing or recognition, and then the control unit searches the corresponding audio from the storage unit for playing. Further, the voice teaching system can also be networked for expansion, such as updating or real-time playing of cloud content.

[0050] As preferred, the base 11 of the support is constructed with a clamping groove 15, and a recognizer is constructed inside or on the edge of the clamping groove 15. A popular science card 4 is detachably connected to the clamping groove 15, and the popular science card 4 is arranged with an identification code. When the popular science card 4 is inserted into the clamping groove 15, the identification code is located on the recognition end of the recognizer, and the voice teaching system calls the stored content corresponding to the popular science card 4. In this scheme, the globe is also provided with a voice teaching function, and the identification code on the popular science card 4 can be used to call the geographical knowledge, earth knowledge or climate knowledge stored in the globe. When in use, one of the popular science cards 4 is inserted into the clamping groove of the base 11, and the corresponding knowledge content can be called for voice playing and teaching. In order to hide and store the popular science card 4 and avoid loss of the popular science card 4, a plurality of sockets 311 are arranged inside the earth model 3, and the popular science card 4 is detachably arranged in the socket 311.
