Description

Technical Field

[0001] The utility model relates to the technical field of digital sand tables, in particular to a 3D holographic lifting digital sand table. Background Art

[0002] A digital sand table is a sand table that is realized through digital projection using sound, light, electricity, images, three-dimensional animation and computer programming technology.

[0003] When using a traditional digital sandbox, its height is generally not adjustable. Since it presents a 3D perspective, if the viewer's viewing height is too high or too low, it will affect the viewing effect and will not be able to see the details. At the same time, in order to facilitate movement, the existing digital sandbox is equipped with four self-locking wheels at the bottom. When it does not need to be moved, the self-locking wheels are locked to prevent it from displacement. However, due to the small contact area between the self-locking wheels and the ground, the placement is not stable enough. Therefore, after locking the self-locking wheels, the electronic sandbox is still prone to a certain displacement, which is not conducive to practical application.

[0004] Therefore, those skilled in the art provide a 3D holographic lifting digital sandbox to solve the problems raised in the above background technology. Utility Model Content

[0012] Through the above technical solution, when the bidirectional screw rotates, it can drive the two sliders to move laterally at the two ends of the bidirectional screw respectively. When the sliders move laterally at the two ends of the bidirectional screw, the connecting rod can be used to drive the bottom platform to move up and down, and the height of the digital sandbox body can be freely adjusted, so that people of different heights can find the best viewing position, thereby ensuring the viewing effect.

[0030] The present invention will be further described in detail below through the accompanying drawings and examples.

[0031] Reference Figure 1 and Figure 5 The embodiment of the utility model provides a 3D holographic lifting digital sandbox, including a digital sandbox body and a bottom plate 7, wherein the digital sandbox body is located above the bottom plate 7. The digital sandbox body is composed of a bottom platform 1, a first light shielding plate 2, a top platform 3, two second light shielding plates 4, a 3D LED display screen 5, and a high-reflection and high-transmittance glass 6. The first light shielding plate 2 is installed between the bottom platform 1 and the top platform 3, the two second light shielding plates 4 are respectively installed between the bottom platform 1, the first light shielding plate 2 and the two ends of the top platform 3, the 3D LED display screen 5 is installed at the bottom of the top platform 3, and the high-reflection and high-transmittance glass 6 is installed obliquely between the bottom platform 1 and the 3D LED display screen 5. When the 3D LED display screen 5 is turned on, the 3D LED display screen 5 projects downward, and through the reflection of light from the high-reflection and high-transmittance glass 6, a virtual 3D image is formed between the bottom platform 1 and the top platform 3, thereby realizing the 3D holographic projection operation of the digital sandbox.

[0032] Telescopic rods 9 are installed on the four corners of the bottom of the bottom platform 1, and four sleeves 8 are installed on the top of the bottom plate 7. The telescopic rods 9 slide inside the corresponding sleeves 8. The sleeves 8 are provided with grooves for use with the telescopic rods 9. The cooperation between the grooves and the telescopic rods 9 allows the telescopic rods 9 to slide better inside the sleeves 8. A baffle is also installed at the bottom of the telescopic rods 9, such as Figure 5 As shown, the baffle can prevent the telescopic rod 9 from escaping from the interior of the sleeve 8.

[0033] Reference Figure 5In one aspect of this embodiment, a lifting assembly is provided between the four sleeves 8, and the lifting assembly is used to adjust the height of the digital sandbox body. The lifting assembly includes two connecting plates 10, a transverse plate 11, a bidirectional screw 12, two sliders 13 and two connecting rods 14. The two connecting plates 10 are respectively installed between the corresponding two sleeves 8. The transverse plate 11 is installed between the two connecting plates 10. The bidirectional screw 12 is rotatably connected between the two connecting plates 10 and is located above the transverse plate 11. The two sliders 13 are respectively threadedly connected to the two ends of the bidirectional screw 12, and the bottoms of the sliders 13 are slidably connected to the tops of the transverse plates 11. When the bidirectional screw 12 rotates, it can drive the two sliders 13 to move laterally at the two ends of the bidirectional screw 12. The connecting rods 14 are respectively rotatably connected to the tops of the sliders 13, and the ends of the connecting rods 14 away from the sliders 13 are rotatably connected to the bottom of the bottom platform 1. When the slider 13 moves laterally at both ends of the bidirectional screw 12, the connecting rod 14 can drive the bottom platform 1 to move up and down, and the height of the digital sandbox body can be freely adjusted, so that people of different heights can find the best viewing position, thereby ensuring the viewing effect.

[0034] One end of the bidirectional screw 12 extends to the outside of the connecting plate 10 and is fixedly connected to a turntable 21. A handle is mounted on the outside of the turntable 21, which facilitates the rotation of the turntable 21 and the bidirectional screw 12. A fastening screw 22 is threadedly connected to the outside of the turntable 21. One end of the fastening screw 22 extends through the turntable 21 and contacts the outside of the connecting plate 10. This contact of the fastening screw 22 with the outside of the connecting plate 10 prevents the bidirectional screw 12 from rotating on its own, thereby ensuring the stability of the equipment during lifting and lowering.

[0035] The top of the horizontal plate 11 is provided with a slide bar, and the bottom of the slider 13 is slidably connected to the slide bar. Figure 5 As shown, the cooperation between the slider 13 and the slide bar ensures that the slider 13 does not rotate along with the bidirectional screw 12 when the bidirectional screw 12 rotates.

[0036] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 5In one aspect of this embodiment, the base plate 7 is further provided with two movable state switching assemblies. Each movable state switching assembly is equipped with two universal wheels 17 at its bottom. The movable state switching assemblies are used to switch the base plate 7 to the ground. The movable state switching assemblies include a first rotating plate 15, a second rotating plate 16, two universal wheels 17, a chute 18, a roller 19, and a hydraulic cylinder 20. The first and second rotating plates 15, 16 are rotatably connected to the bottom of their respective sleeves 8. The two universal wheels 17 are mounted on the ends of the first and second rotating plates 15, 16, respectively, away from each other. Using the universal wheels 17 to ground facilitates movement of the equipment. A chute 18 is provided at the bottom of the first rotating plate 15. A roller 19 is rotatably connected to the end of the second rotating plate 16 closer to the first rotating plate 15. The roller 19 is in rolling connection with the chute 18. The rolling connection between the roller 19 and the chute 18 enables one end of the second rotating plate 16 to contact the bottom of the first rotating plate 15. The hydraulic cylinder 20 is rotatably connected to the outside of the sleeve 8, and the piston rod of the hydraulic cylinder 20 is rotatably connected to the top of the corresponding first rotating plate 15. The operation of the hydraulic cylinder 20 can drive the first rotating plate 15 to rotate, so as to better switch the state. The hydraulic cylinder 20 is electrically connected to the external control device to control the operation of the hydraulic cylinder 20.

[0037] Working principle:

[0038] When using, Figure 3 and Figure 4 As shown, at this time, the bottom plate 7 is on the ground, the device is placed stably, the device is powered on, and the hydraulic cylinder 20 is electrically connected to the external control device;

[0039] Then, the 3D LED display screen 5 is turned on, and the 3D LED display screen 5 projects downwards. Through the light reflection of the high-reflection and high-transmittance glass 6, a virtual 3D image is formed between the bottom platform 1 and the top platform 3, thereby realizing the 3D holographic projection operation of the digital sand table;

[0040] When the height of the digital sand table body needs to be adjusted, the turntable 21 and the bidirectional screw 12 are rotated by the handle. When the bidirectional screw 12 is rotated, the two sliders 13 can be driven to move laterally at the two ends of the bidirectional screw 12 respectively. When the sliders 13 move laterally at the two ends of the bidirectional screw 12, the connecting rod 14 can be used to drive the bottom platform 1 to be raised and lowered, so that the height of the digital sand table body can be freely adjusted, so that people of different heights can find the best viewing position, thereby ensuring the viewing effect. After adjusting the height of the device, the fastening screw 22 is used to contact the outer side of the connecting plate 10 to prevent the bidirectional screw 12 from rotating on its own, thereby ensuring the stability of the device lifting;

[0041] When the equipment needs to be moved, the hydraulic cylinder 20 is controlled by an external control device to work, and its piston rod is used to drive the first rotating plate 15 to rotate downward. At the same time, the rolling connection between the slide groove 18 and the roller 19 is used to make the second rotating plate 16 rotate downward, so that the first rotating plate 15 and the second rotating plate 16 are rotated to a horizontal state. At this time, the universal wheels 17 at the bottom of the first rotating plate 15 and the second rotating plate 16 touch the ground and lift the bottom plate 7, so that there is a gap between the bottom of the first rotating plate 15 and the ground. Figure 1 and Figure 2 As shown, the device can now be pushed to move by the universal wheel 17;

[0042] After moving to the designated position, the hydraulic cylinder 20 is controlled by the external control device to work, and its piston rod drives the first rotating plate 15 to rotate upward. At this time, under the action of the gravity of the equipment, the ground hits the universal wheel 17, causing the second rotating plate 16 to rotate upward as well, until Figure 3 and Figure 4 In the state shown, the bottom of the bottom plate 7 contacts the ground and supports the entire device. At this time, the universal wheels 17 at the bottom of the second rotating plate 16 and the bottom of the universal wheels 17 at the bottom of the first rotating plate 15 only contact the ground.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
