[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 4 As shown, the globe in this embodiment includes a support base 1, a sphere 2, a mounting base 3, a pendulum 4, a lamp body 5, a first drive mechanism 6, a second drive mechanism 7, a control module and an information input module. The control module is connected to the lamp body 5, the first drive mechanism 6, the second drive mechanism 7 and the information input module by electrical signals.

[0031] The support base 1 is used to support the sphere 2, and the sphere 2 is rotatably set on the support base 1, so that based on the rotation of the sphere 2, it is convenient for the user to view different geographical information on the sphere 2.

[0032] The structure of the support seat 1 is specifically set according to the needs. In this embodiment, in order to improve the stability of the rotation connection of the ball 2 on the support seat 1, the support seat 1 includes a base 11 and a C-shaped frame 12 connected to the base 11, and the ball 2 is rotatably set between the two ends of the C-shaped frame 12. Specifically, one extreme position of the ball 2 is rotatably connected to one end of the C-shaped frame 12 through a first connecting member 21, and the other extreme position of the ball 2 is rotatably connected to the other end of the C-shaped frame 12 through a second connecting member 22. The first connecting member and the second connecting member can realize the stable and smooth rotation of the ball 2 on the C-shaped frame 12.

[0033] The mounting seat 3 is arranged inside the sphere 2 for mounting structures such as the pendulum rod 4, the lamp body 5, the first driving mechanism 6, and the second driving mechanism 7, so that the light emitted by the lamp body 5 is irradiated onto the sphere 2 from inside the sphere 2, so that the external structure of the globe remains simple, and the volume of the globe is not increased, and the user's observation line of sight is not blocked.

[0034] Specifically, the lower end of the mounting seat 3 passes through the pole of the sphere 2 and is connected to the end of one end of the C-shaped frame 12, so that the mounting seat 3 is fixedly mounted on the support seat 1. The portion of the mounting seat 3 passing through the sphere 2 is in the shape of an axis, and the first connecting member is sleeved outside the portion of the mounting seat 3 passing through, so that the sphere 2 is supported on the C-shaped frame 12 for rotation.

[0035] In order to save the volume of the mounting base 3 and ensure the adjustment of the longitude and latitude illumination position of the lamp body 5, the mounting base 3 in this embodiment is axial in shape as a whole, and the mounting base 3 extends along the axis between the two poles of the sphere 2. The part of the mounting base 3 used to install other structural parts is widened.

[0036] The first end of the swing rod 4 is rotatably connected to the mounting seat 3 corresponding to the center of the sphere 2 , and the lamp body 5 is arranged on the second end of the swing rod 4 .

[0037] The first driving mechanism 6 is arranged on the mounting seat 3 and is drivingly connected to the swing rod 4. The first driving mechanism 6 drives the swing rod 4 to rotate along the longitude line direction, thereby adjusting the latitude position of the lamp body 5 relative to the sphere 2. The second driving mechanism 7 is arranged on the mounting seat 3. The driving mechanism is drivingly connected to the sphere 2 and drives the sphere 2 to rotate along the latitude line direction, thereby adjusting the longitude position of the lamp body 5 relative to the sphere 2.

[0038] The first driving mechanism 6 includes a first motor 61, a toothed disc 62 and a first gear 63, and the first motor 61 is connected to the control module by electrical signals. The first motor 61 is fixedly arranged on the swing rod 4, the toothed disc 62 is fixedly arranged on the mounting seat 3 corresponding to the center of the sphere 2, and the first gear 63 is connected to the driving end of the first motor 61 and meshes with the toothed disc 62. The first gear 63 and the toothed disc 62 are meshed by an external meshing structure. When in use, with the forward and reverse rotation of the first motor 61, the first gear 63 can be driven to rotate, and based on the meshing of the first gear 63 and the toothed disc 62, and the fixed position of the toothed disc 62, the first gear 63, the first motor 61, and the swing rod 4 will move along the longitude line accordingly, so as to realize the rotation drive of the lamp body 5 on the longitude line, and achieve the purpose of adjusting the longitude position of the lamp body 5 relative to the sphere 2. And in this structure, the diameter of the first gear 63 is much smaller than the diameter of the toothed disc 62, so that the first motor 61 can relatively accurately control the relationship between the number of rotations and the rotation angle on the longitude line.

[0039] The second driving mechanism 7 includes a second motor 71 and a second gear 72. The second motor 71 is connected to the control module by electrical signals. The second motor 71 is fixed on the mounting seat 3. The second gear 72 is connected to the driving end of the second motor 71 corresponding to the pole position of the sphere 2. The second gear 72 is provided with a connecting shaft connected to the pole of the sphere 2. Specifically, the second motor 71 is arranged at the upper end of the mounting seat. The connecting shaft of the second gear 72 extends and is rotated and limited on the C-shaped frame 12 through the transmission of the pole position of the sphere. The second connecting member 22 is sleeved outside the connecting shaft of the second gear 72 to realize the installation of the sphere 2 on the C-shaped frame 12. When in use, the second motor 71 rotates, driving the second gear 72 to rotate, and the corresponding connecting shaft on the second gear 72 also rotates, driving the sphere 2 to rotate in the latitude direction relative to the mounting seat 3, thereby realizing the adjustment of the longitude position of the lamp body 5 relative to the sphere 2.

[0040] Since the rotation angle of the output shaft of the second motor 71 directly corresponds to the rotation angle of the sphere 2, that is, the output of the second motor 71 rotates one circle, and the corresponding sphere 2 also rotates one circle, it is necessary to control the rotation angle of the output shaft of the second motor 71 very accurately, otherwise it will cause a large driving error. Based on this, in order to accurately control the longitude rotation amount, a third gear 73 with a rotating shaft 731 is provided on the mounting seat 3, and the third gear 73 is rotatably connected to the mounting seat 3 and meshed with the second gear 72. A magnetic member 8 is provided on the rotating shaft 731. In this way, through the meshing of the second gear 72 and the third gear 73, the rotation angle of the magnetic member 8 on the rotating shaft 731 can directly reflect the rotation angle of the second motor 71. The control module includes a circuit board 9 fixed on the mounting seat 3, and an encoder 91 for electromagnetic communication with the magnetic member 8 is provided on the circuit board 9 corresponding to the magnetic member 8. The encoder 91 obtains the rotation angle of the magnetic member 8 through electromagnetic communication with the magnetic member 8, and then transmits its detection signal to the control module, and the control module accurately controls the rotation angle of the second motor 71 accordingly.

[0041] The information input module is arranged on the support seat 1, and the user can input specific location information to the control module through the information input module. The control module controls the first driving mechanism 6 and the second driving mechanism 7 to work based on the information input module, drives the lamp body 5 to be located at a position relative to the sphere 2 to illuminate the input location, and then controls the lamp body 5 to light up, thereby realizing lighting up a specific location. The information input module includes a wireless communication module, a voice module and / or an information input screen, and a working chip capable of parsing the corresponding signal is provided in the corresponding control module. In this way, the user can input the geographical location that needs to be illuminated by the lamp body 5 to the control module through the information input module, and the control module obtains the corresponding target latitude and longitude after parsing the geographical information. The control module determines the latitude and longitude position corresponding to the lamp body 5 based on the working parameters of the first motor 61 and the second motor 71, and then compares and calculates with the target longitude and latitude information to determine the driving direction and driving angle of the first motor 61 and the second motor 71. The control module controls the first driving mechanism 6 and the second driving mechanism 7 to drive the lamp body 5 to align with the geographical location to be illuminated on the sphere 2, and then lights up the corresponding geographical location, so that it is convenient for users to quickly find a specific location on the earth.

[0042] The globe of the utility model is provided with a swing rod 4 to realize the support and installation of the lamp body 5, and the first driving mechanism 6 is used to drive the swing rod 4 to rotate to realize the latitude position adjustment of the lamp body 5. On this basis, the second driving mechanism 7 is used to realize the overall drive of the mounting base 3 to achieve the purpose of adjusting the longitude position of the lamp body 5. In this way, based on the cooperation of the first driving mechanism 6 and the second driving mechanism 7, the illumination of a specific position on the sphere 2 is finally realized, which is convenient for users to quickly find a specific position on the globe, with high efficiency and excellent use experience.
