[0018] 1. The present invention is provided with a cover plate, a conductive electromagnet and a fixed magnet. After the conductive electromagnet is energized, the conductive electromagnet and the fixed magnet repel each other.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 6 , the present invention provides the following technical solutions:

[0029] Embodiment 1: An AR interactive display device comprises a universal converter 2 and a display instrument 4, the universal converter 2 is mounted on a bracket 1, the display instrument 4 is mounted on the universal converter 2, a camera is mounted on the back of the display instrument 4, the outer side of a moving rod 8 and the inner side of a mounting column 9 fit together, the moving rod 8 is a non-cylindrical structure, the moving distance of the moving rod 8 is greater than the overlapping distance between the moving rod 8 and the mounting column 9, the mounting column 9 and the universal converter 2 are located on the same horizontal plane; a moving groove 12 is provided inside the bracket 1, the moving rod 8 is inserted into the moving groove 12, a moving groove 12 is provided between one end of the moving rod 8 close to the moving groove 12 and the bracket 1, the other end of the moving rod 8 is inserted into the mounting column 9, the mounting column 9 is mounted on both sides of the display instrument 4, the moving rod 8 is a pentagonal prism, and the rotation angle of the universal converter 2 is an integer multiple of 72.

[0030] An AR experience area is set up in rural scenic spots, where tourists can learn about local characteristics through AR games or interactions, increase the fun and education of tourism, and use the display instrument 4 to experience the history, culture, and natural scenery of the countryside. When the experiencer needs to adjust the angle of the display instrument 4, he pulls the moving rod 8 to both sides with his hands, and the moving rod 8 moves toward the inside of the moving groove 12 until the moving rod 8 is separated from the mounting column 9. Then, the display instrument 4 is rotated, and the display instrument 4 rotates around the universal converter 2. The rotation angle of the universal converter 2 is an integer multiple of 72, so that the moving rod 8 can be normally inserted into the inside of the mounting column 9. Then, let go of your hand, and the elastic force of the reset spring 14 moves the moving rod 8 outward, and the moving rod 8 is inserted into the inside of the mounting column 9. The structure of the moving rod 8 and the mounting column 9 is used to limit the mounting column 9, and then the display instrument 4 is limited, so as to avoid the instability of the display instrument 4 affecting the normal recording of the camera, which can improve the AR interactive experience of tourists.

[0031] Embodiment 2: The difference between this embodiment and embodiment 1 is that the moving rod 8 is an octagonal prism, and the rotation angle of the universal converter 2 is an integer multiple of 45.

[0032] The rotation angle of the universal converter 2 is an integer multiple of 45, so that the moving rod 8 can be normally inserted into the interior of the mounting column 9, and fixation is achieved through the structure of the moving rod 8. The more prisms the moving rod 8 has, the more rotation angles the display instrument 4 can have, and the more convenient it is to adjust the angle of the display instrument 4, and better angle records can be found.

[0033] A blocking mechanism is installed on the bracket 1, and the surface of the display instrument 4 can be protected by the blocking mechanism to prevent the display instrument 4 from being exposed to excessive dust for a long time and affecting the normal operation of the display instrument 4. A mounting rod 3 is installed on the side end of the bracket 1, and a fixed magnet 10 is installed on the other end of the mounting rod 3. The blocking mechanism includes a lower contact 11, an electromagnet 6 and a cover plate 5. Several guide rods 7 are slid inside the fixed magnet 10. The end of the guide rod 7 close to the display instrument 4 is installed with an electromagnet 6, and the other side of the electromagnet 6 is installed with a cover plate 5. The electromagnet 6 and the fixed magnet 10 repel each other when powered on. The moving distance of the cover plate 5 is equal to half the length of the display instrument 4. A connecting spring 13 is installed between the electromagnet 6 and the fixed magnet 10. The cover plate 5 is located on the side of the display instrument 4, and the cover plate 5 fits the surface of the display instrument 4.

[0034] When the upper contact 15 is energized, the display instrument 4 rotates to a vertical state, the electromagnet 6 is powered on, the electromagnet 6 and the fixed magnet 10 repel each other, and the repulsive force causes the electromagnet 6 to move to the middle position. During the movement of the electromagnet 6, the cover 5 is driven to move synchronously. The cover 5 moves to the surface of the display instrument 4 to block it, so as to prevent the display instrument 4 from being placed for a long time and the dust on the surface affects its normal operation later. No personnel are required to operate the cover 5.

[0035] The electromagnet 6 is electrically connected to the upper contact 15, several upper contacts 15 are electrically connected, several lower contacts 11 are electrically connected, the lower contact 11 is electrically connected to the battery, the connecting rod 16 slides inside the bracket 1, a lifting plate 17 is installed at the end of the connecting rod 16, the upper contact 15 is installed at the bottom of the lifting plate 17, the lower contact 11 is installed on the bracket 1, and a mounting spring 18 is installed between the connecting rod 16 and the bracket 1. The lifting distance of the connecting rod 16 is equal to half the width of the display instrument 4.

[0036] When the display instrument 4 is pushed toward the side close to the lifting plate 17, the display instrument 4 rotates to contact with the lifting plate 17, and the display instrument 4 rotates to make the lifting plate 17 move downward. During the downward movement of the lifting plate 17, the upper contact 15 is driven to move downward synchronously. When the display instrument 4 is rotated to a vertical state, the upper contact 15 is just in contact with the lower contact 11, and the upper contact 15 and the electromagnet 6 are connected to the power supply. A repulsive force is generated between the electromagnet 6 and the fixed magnet 10, and the repulsive force causes the electromagnet 6 and the cover plate 5 to move toward the middle position. When the display instrument 4 needs to be used, the power supply is disconnected. At this time, the repulsive force between the electromagnet 6 and the fixed magnet 10 disappears, and the elastic force of the connecting spring 13 causes the electromagnet 6 to move toward the side close to the fixed magnet 10. During the movement of the electromagnet 6, the cover plate 5 is driven to move synchronously toward the side close to the fixed magnet 10, and the cover plate 5 is separated from the display instrument 4, and then the display instrument 4 needs to be operated again according to needs.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
