Description

Technical Field

[0001] The present invention relates to the field of AR-holographic intelligent teaching technology, and in particular to an AR-holographic intelligent device that can be used for computer visualization teaching. Background Art

[0002] AR-holography refers to a technology that combines augmented reality with holographic projection. AR captures images of the real world through a camera and overlays virtual information onto them using computer graphics, merging the virtual and the real. Holographic projection, on the other hand, utilizes the principles of optical interference and diffraction to record and reproduce three-dimensional images of objects, creating a realistic 3D effect.

[0003] Holographic projection uses the principles of optical interference and diffraction to record and reproduce three-dimensional images of objects. Holographic projection technology can create realistic three-dimensional images, providing viewers with an immersive experience. Holographic projection technology is widely used in exhibitions, performances, advertising, and other fields. True holographic technology can record all the information of an object's light waves and maintain consistency when viewed from different angles. However, most holographic projection technologies on the market are pseudo-holographic, achieving a similar effect through multiple imaging planes.

[0004] AR holographic projection technology is being used more and more widely in various fields, especially in computer teaching, which makes it easier for teachers to display teaching content more comprehensively.

[0005] For example, an AR smart projection device with application number 202311064684.7 uses a terminal to transmit a signal to a signal receiver, and then turns on the holographic projector after passing through the processor. At this time, the semiconductor refrigeration plate begins to generate cold air, and the cooling fan brings the cold air into the projection box to cool down the processor and the holographic projector, and then discharges it from the air outlet. The support component supports the bottom box, and the rotating component can make the projection box automatically rotate according to the direction of the user's movement. Secondly, the signal enhancement component can increase the quality of network transmission and downloading. In this way, the processor is cooled to avoid processor heating, maintain the normal operation of the holographic projector, and improve the operator's viewing experience. However, the device still has certain defects;

[0006] The height of the AR smart projector cannot be adjusted. When using the AR smart projector, it needs to be placed on a support surface with a certain height. When fine-tuning the projection position is required, the user can only look for support tools on site, which is not convenient enough.

[0007] Therefore, we propose an AR-holographic intelligent device that can be used for computer visualization teaching to solve the above problems. Summary of the Invention

[0018] With the above structural design, when the height of the AR holographic intelligent projection device needs to be adjusted, the threaded sleeve is rotated to move the threaded sleeve downward. At this time, the threaded hollow column releases the fixation of the movable rod, and then the movable rod is pulled upward or downward to adjust the height of the AR holographic intelligent projection device through the movable rod. After the adjustment is completed, the threaded sleeve is rotated to move the threaded sleeve upward, so that the threaded sleeve squeezes the head of the threaded hollow column, thereby squeezing and fixing the movable rod through the threaded hollow column.

The threaded sleeve 11 is threadedly connected to the threaded hollow column 9. The arc groove 12 above the threaded sleeve 11 is designed with an inclined structure. The head position of the threaded hollow column 9 is under the action of the opening 10. When subjected to force, it can be tightened inward to squeeze and fix the movable rod 13. When the height of the AR holographic intelligent projection device 16 needs to be adjusted, the threaded sleeve 11 is rotated to move the threaded sleeve 11 downward. At this time, the threaded hollow column 9 releases the fixation of the movable rod 13, and then the movable rod 13 is pulled upward or downward to adjust the height of the AR holographic intelligent projection device 16 through the movable rod 13.

A sealing plug 20 is provided on the heat dissipation port 19. The sealing plug 20 and the heat dissipation port 19 are detachably connected. The atomizing nozzle 26 is located below the heat dissipation port 19. When the AR holographic intelligent projection device 16 is in use, the atomizing nozzle 26 is opened. Open the sealing plug 20, the cold water in the cold water tank 18 can be cooled through the heat dissipation port 19. At the same time, the AR holographic intelligent projection device 16 will not be used for a long time. Therefore, the cold water in the cold water tank 18 is cooled at room temperature to meet the heat dissipation of the AR holographic intelligent projection device 16. The structure is simple and the production cost is low. A circulating water pump 21 is installed on the left side of the cold water tank 18, and an inlet pipe 22 and an outlet pipe 23 are installed on the left and rear sides of the circulating water pump 21 respectively.

The circulating water pump 21 is started. The circulating water pump 21 extracts the cold water in the cold water tank 18 through the water inlet pipe 22, and then transports the water to the water cooling pipe 24 through the water outlet pipe 23. The water in the water cooling pipe 24 is transported to the atomizing nozzle 26 through the drain pipe 25. The atomizing nozzle 26 sprays the water into the cold water tank 18. When spraying water, the atomizing nozzle 26 can spray water over a larger area. The water dissipates heat, thereby reducing the temperature rise rate of the circulating water in the cold water tank 18. A water-cooling pipe 24 is arranged between the heat dissipating fins 17.

[0051] Working principle: When using the AR-holographic intelligent device that can be used for computer visualization teaching, first, rotate the threaded sleeve 11 to move the threaded sleeve 11 downward. At this time, the threaded hollow column 9 releases the fixation on the movable rod 13, and then pulls the movable rod 13 upward or downward to adjust the height of the AR holographic intelligent projection device 16 through the movable rod 13. After the adjustment is completed, rotate the threaded sleeve 11 to move the threaded sleeve 11 upward, so that the threaded sleeve 11 squeezes the head of the threaded hollow column 9, thereby squeezing and fixing the movable rod 13 through the threaded hollow column 9, and adjusting the height of the AR holographic intelligent projection device 16 to a position convenient for students to watch.

[0052] Start the circulating water pump 21, which pumps the cold water out of the cold water tank 18 through the water inlet pipe 22, and then transports the water to the water cooling pipe 24 through the water outlet pipe 23. The water in the water cooling pipe 24 is transported to the atomizing nozzle 26 through the drain pipe 25. The atomizing nozzle 26 sprays the water into the cold water tank 18. When spraying water, the atomizing nozzle 26 can dissipate heat over a larger area of ​​the sprayed water, thereby reducing the heating rate of the circulating water in the cold water tank 18. Through the design of the heat dissipation fins 17 and the water cooling pipe 24, the AR holographic intelligent projection device 16 can be dissipated to a greater extent, thereby improving the heat dissipation efficiency of the AR holographic intelligent projection device 16.

[0053] When the AR holographic intelligent projection device 16 needs to be disassembled, the adjusting bolt 29 is rotated, and the adjusting bolt 29 drives the top plate 27 to move upward, and the top plate 27 can drive the water-cooling pipe 24 to move upward. At the same time, the top plate 27 drives the abutment block 31 to move upward, so that the abutment block 31 is disengaged from the limit block 34. The limit block 34 moves upward under the action of the rebound force of the telescopic spring 36, and then the AR holographic intelligent projection device 16 can be pulled out, and the positioning bolt 6 is rotated to disengage the positioning bolt 6 from the positioning groove 5 on the reinforced movable frame 4, and then the counterweight base 1 is rotated to complete the storage of the counterweight base 1, so that the device does not take up a large space when idle.
