[0040] Embodiment 1:

[0041] Please refer to Figure 1 - Figure 6 , a new holographic projection device, which includes:

[0042] A peripheral fixed frame 1 is provided with a central fixed frame 2 in the middle of the inner side of the peripheral fixed frame 1, and a rotating frame 3 is provided below the central fixed frame 2. A rotating assembly is provided at one end of the rotating frame 3, and the rotating frame 3 is rotatably connected to the central fixed frame 2 through the rotating assembly, and the other end of the rotating frame 3 is slidably connected to the inner side of the peripheral fixed frame 1; further, two rows of large balls 7 are provided at the other end of the rotating frame 3, and the two rows of large balls 7 are arranged in parallel up and down, and the number of large balls 7 in each row is a certain number, and a large guide groove 8 is opened on the inner side of the peripheral fixed frame 1, and the large balls 7 are located inside the large guide groove 8, and the end of the rotating frame 3 is rollingly connected to the large guide groove 8 through the large balls 7; through the cooperation of the large balls 7 and the large guide groove 8, when the rotating frame 3 rotates with the central fixed frame 2 as the axis, the other end of the rotating frame 3 is not easy to shake, so that the rotation adjustment of the rotating frame 3 is relatively stable.

[0043] A connecting seat 4 is arranged at a position below the rotating frame 3, a projector 5 is arranged at the lower end of the connecting seat 4, a connecting slide groove 6 is opened in the middle part of the rotating frame 3 along the length direction, the upper end of the connecting seat 4 is located on the inner side of the connecting slide groove 6, a sliding component is arranged on the top of the connecting seat 4, and the upper end of the connecting seat 4 is slidably connected with the connecting slide groove 6 through the sliding component.

[0044] It can be seen that the direction of the rotating frame 3 can be adjusted by the rotating assembly, and the position of the connecting seat 4 can be adjusted by the sliding assembly to achieve the position adjustment of the projector 5. Through the cooperation of the peripheral fixing frame 1, the central fixing frame 2, the rotating frame 3, and the connecting seat 4, the projector 5 can be arbitrarily adjusted within the range inside the peripheral fixing frame 1. According to the needs, a full range of intelligent AR can be used in conjunction with the projection equipment to achieve an immersive atmosphere, which is particularly different from the traditional auditorium, with a stronger sense of substitution and more convenience.

[0045] Embodiment 2:

[0046] The new holographic projection device provided in Example 1 is further optimized. Specifically, Figure 7As shown, the rotating assembly includes a connecting disk 9, which is fixed to the upper part of the rotating frame 3 near one end of the central fixed frame 2. The cross-section of the connecting disk 9 is set to be T-shaped, and a small ball 10 is set at the inner lower part of the connecting disk 9. The number of small balls 10 is several, and the several small balls 10 are arranged in a ring array. A rotating groove 12 is opened inside the central fixed frame 2, and a small guide groove 13 is opened at the lower part of the peripheral side of the rotating groove 12. The connecting disk 9 is located inside the rotating groove 12, and the connecting disk 9 is rotatably connected to the rotating groove 12. The small ball 10 is located inside the small guide groove 13, and the small ball 10 is rollingly connected to the small guide groove 13.

[0047] Furthermore, in order to achieve the rotation limit of the rotating frame 3, a limit knob 11 is provided at the lower part of the rotating frame 3 near one end of the central fixed frame 2, one end of the limit knob 11 passes through the rotating frame 3 and fits against the lower end of the central fixed frame 2, and the limit knob 11 is threadedly connected to the rotating frame 3.

[0048] Through the above structural design, when the rotating frame 3 rotates, the rotating connection between the rotating frame 3 and the central fixed frame 2 is realized through the cooperation between the connecting plate 9 and the rotating groove 12, and the friction of the rotation can be reduced through the cooperation between the small ball 10 and the small guide groove 13, so that the rotation of the rotating frame 3 is more labor-saving. After the rotating frame 3 rotates, the friction between the limit knob 11 and the central fixed frame 2 is increased by tightening the limit knob 11, so as to realize the rotation limit of the rotating frame 3.

[0049] Embodiment 3:

[0050] The new holographic projection device provided in Example 1 is further optimized. Specifically, Figure 8-Figure 9 As shown, the sliding assembly includes a disk body 15, which is fixed on the top of the connecting seat 4. The disk body 15 is located below the rotating frame 3. A connecting protrusion 16 is fixedly connected to the middle of the upper end of the disk body 15. The connecting protrusion 16 extends to the inner side of the connecting slide groove 6. Both sides of the connecting protrusion 16 are rotatably connected to guide wheels 17. The inner wall of the connecting slide groove 6 is fixedly connected to the guide rail 14 along the length direction, and the guide wheel 17 is rollingly connected to the guide rail 14 on the same side.

[0051] Furthermore, in order to achieve the movement limit of the connecting seat 4, limit knobs 18 are provided on both sides of the lower end of the disk body 15. The upper end of the limit knob 18 passes through the disk body 15 and fits with the lower end of the rotating frame 3. The limit knob 18 is threadedly connected to the disk body 15.

[0052] Through the above-mentioned structural design, when the connecting seat 4 moves, the sliding connection between the connecting seat 4 and the rotating frame 3 is realized through the cooperation of the guide wheel 17 and the guide rail 14, and the movement of the connecting seat 4 can be relatively smooth through the cooperation of the guide wheel 17 and the guide rail 14. After the connecting seat 4 moves, the friction between the limit knob 18 and the rotating frame 3 is increased by tightening the limit knob 18, thereby realizing the movement limit of the connecting seat 4.
