Description

Technical Field

[0001] The utility model relates to the technical field of digital sand tables, and in particular to a lifting type holographic digital sand table with an AR slide screen. Background Art

[0002] Digital sand table is realized by using sound, light, electricity, image, 3D animation and computer program control technology, and digital projection. Digital sand table can fully reflect the characteristics of the location and achieve a vivid and varied dynamic visual effect. It is a brand new experience for visitors and can generate strong resonance, which is more intuitive than traditional sand table models.

[0003] At present, in order to better display the sand table model, some local positions in the existing sand table need to use mobile display screens for display. The display screen uses AR technology to demonstrate the model of the local position in the sand table in detail. However, due to the high cost of such screens, it is not convenient to store and protect them when not in use. In the idle state, they are easily affected by the external environment, resulting in an increase in their failure rate, which in turn increases the burden of later maintenance and inspection. In view of this, we propose a lifting holographic digital sand table with an AR slide screen. Utility Model Content

During the descent, the inclined surface structure of the inclined surface 2 312 is conducive to abutting against the edge position of the top of the inner wall of the receiving box 401 and driving the inclined surface 1 311 to automatically retract toward the inside of the movable groove 307 to avoid jamming during retraction. When the AR display screen assembly 3 descends to the extreme position, the folding curtain 403 is pulled to unfold it and close the rectangular opening groove 402, thereby realizing the storage protection of the AR display screen body 304.
