Description

Technical Field

[0001] The utility model relates to the technical field of projection equipment, in particular to a holographic 3D projection equipment. Background Art

[0002] Holographic 3D projection is a 3D technology that uses the principles of interference and diffraction to record and reproduce the real three-dimensional image of an object. It allows viewers to see three-dimensional virtual characters without wearing glasses. Its basic principle is: during the shooting process, the principle of interference is used to record the light wave information of the object, and during the imaging process, the principle of diffraction is used to reproduce the light wave information of the object, thereby reproducing the real three-dimensional image of the object.

[0003] With the further development of holographic 3D projection technology, many industries have developed equipment made of holographic 3D projection principles according to their own needs, such as surgical simulators in the medical industry and driving simulators in the automotive industry. As the use of the equipment expands, the hardware shortcomings of existing holographic 3D projection equipment are constantly exposed. For example, the authorized patent for a display control device for holographic projection for live broadcasting with announcement number CN217606245U discloses a technical solution of "providing support for the holographic projection board through a base in conjunction with a suction cup, and providing power for the internal circuit equipment through a power access port in conjunction with a battery" in order to solve the problem of poor stability of the currently used holographic 3D projection equipment on the placement surface. However, in actual use, the suction cup is prone to leakage during long-term use, resulting in a gradual decrease in the negative pressure adsorption strength. The problem of stable placement of the holographic 3D projection equipment has not been completely solved. Secondly, during the use of the holographic 3D projection equipment, there is a lack of technical means for the dust covering the projection surface of the holographic 3D projection equipment, and the above-mentioned prior art does not have relevant technical means.

[0035] Working principle:

[0036] Embodiment 1

[0037] For the stability of the whole device on the placement surface, the axial flow fan 93 inside the air generating component 9 and the valve inside the transition valve tube 11 are opened, and the axial flow fan 93 forces airflow inside the support sleeve 91 and delivers gas to the corresponding annular airbag 121 through the transition valve tube 11.

[0038] The compressed T-shaped sleeve 133 will drive the suction cup body 131 to move downward and press the placement surface, and then discharge the internal space of the suction cup body 131, so that the suction cup body 131 and the placement surface are in a negative pressure adsorption connection state. Similarly, the other three suction cup bodies 131 are also in the same negative pressure adsorption state, thereby fully ensuring the stability of the device on the placement surface;

[0039] Then, the internal valve of the transition valve tube 11 is closed, and the annular airbag 121 in the expanded state will continue to apply pressure to the corresponding suction cup body 131 .

[0040] Embodiment 2

[0041] For the dust cleaning problem on the surface of the holographic projection plate 2, the brake servo motor inside the electric output component 10 is first started, and the brake servo motor drives the corresponding composite air supply pipe 5 through the bevel gear box to rotate synchronously, and then the two composite air supply pipes 5 are relatively rotated and adjusted under the meshing transmission of the two gears 8 until the ports of the guide branch pipes 52 in the two composite air supply pipes 5 are tilted and aligned with the surface of the holographic projection plate 2, and the brake servo motor is closed;

[0042] The axial flow fan 93 inside the air generating component 9 is turned on, and the axial flow fan 93 forces air flow inside the supporting box 91 and passes through the corresponding air supply pipe 51 in the composite air supply pipe 5. Then, under the guidance of the elastic hose 6, the other air supply pipe 51 is also filled with air flow, and finally, it is sprayed to the surfaces of the front and rear ends of the holographic projection plate 2 through multiple guide branch pipes 52 for automatic air blowing and dust cleaning.

[0043] Embodiment 3

[0044] For the cleaning of dust on the surface of the holographic projection plate 2, the brake servo motor inside the electric output component 10 is started and outputs forward and reverse rotations at a certain angle, and then the brake servo motor drives the corresponding composite air delivery pipe 5 through the bevel gear box to rotate synchronously, and then the two composite air delivery pipes 5 are relatively reciprocated and adjusted under the meshing transmission of the two gears 8;

[0045] The axial flow fan 93 inside the air producing component 9 is turned on, and the axial flow fan 93 forces air flow inside the supporting box 91 and passes through the corresponding air supply pipe 51 in the composite air supply pipe 5. Then, under the guidance of the elastic hose 6, the other air supply pipe 51 is also filled with air. Finally, the surfaces of the front and rear ends of the holographic projection plate 2 are respectively cleaned by air blowing through a plurality of guide branch pipes 52 to achieve automatic dust cleaning.
