Description

Technical Field

[0001] This utility model relates to the field of holographic projection technology, specifically a gesture-triggered holographic projection device. Background Technology

[0002] The gesture-triggered holographic projection device is a device that integrates holographic projection, gesture recognition, dynamic narrative and multi-sensory linkage technologies. It allows visitors to trigger different plot branches through gestures and participate in the real-time reconstruction of historical scenes of Shule Ancient City in an immersive way. Through holographic imaging technology, it presents three-dimensional historical scenes such as "Ancient Road of the Western Regions" and "Shule Beacon Tower" in the air or on a specific medium. The holographic fan-type 3D projection interactive device is a typical application device of gesture-triggered holographic projection technology. It uses high-speed rotating fan blades (LED array) to project three-dimensional holographic images in the air by utilizing the persistence of vision. At the same time, the device is equipped with a gesture recognition module that can capture the gestures of visitors and trigger preset image content or plot branches to achieve a "participatory" holographic interactive experience. In the operation of gesture-triggered holographic projection devices, the device relies on high-speed rotating fan blades to achieve holographic imaging. When the fan blades are rotating, the visual persistence effect creates a visual illusion of "semi-transparency" or even "invisibility." However, when tourists participate in the interaction, their attention is completely focused on the holographic image and gestures, making it easy for them to overlook the physical existence of the fan blades. Children and tourists who lack knowledge of technological devices may unconsciously reach out and touch the high-speed rotating fan blades out of curiosity or because they are attracted by the image. The high-speed fan blades can directly cause cuts, pinches, or even more serious mechanical injuries due to limbs being caught in them. Therefore, a gesture-triggered holographic projection device is proposed to address the above problems. Utility Model Content

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A gesture-triggered holographic projection device includes a power supply bracket 1. Protective components 5 are fixedly connected to both sides of the bottom of the power supply bracket 1. The protective components 5 include a cleaning component 51. Support rods 52 are fixed at the four corners of the upper end of the cleaning component 51. Slide grooves 53 are formed on both sides of the inner side of the support rods 52. Tension springs 54 are fixed to the upper end of the slide grooves 53, and hooks 55 are fixed to the lower end of the tension springs 54. The cleaning component 51 includes a cleaning shell 511. A cleaning groove 512 is formed on the inner side of the cleaning shell 511. An arc-shaped groove 513 is formed at the opening of the cleaning groove 512. A cleaning block 514 and a sponge block 515 are embedded inside the arc-shaped groove 513 and are bonded together. A spiral spring 57 is fixed to both ends of the inner wall of the cleaning shell 511. A rotating shaft 56 is fixed to the inner ring of the spiral spring 57. A transparent plastic plate 58 is fixed to the outer side of the rotating shaft 56. A support plate 59 is fixed to the upper end of the transparent plastic plate 58. Hanging holes 510 are formed on the inner sides of both ends of the support plate 59.

[0017] It should be noted that: a storage control module 2 is fixed on the upper end of the power supply bracket 1, a gesture capture sensor 3 is fixedly connected to the upper end of the storage control module 2, a high-speed rotating fan blade 4 is fixedly connected to one side of the storage control module 2, there are four support rods 52, which are fixed vertically at the four corners of the upper end of the cleaning component 51, and each support rod 52 has a long groove 53 on its inner side, which extends along the length of the support rod 52. A transparent plastic plate 58 is rolled up and wrapped around the outside of the rotating shaft 56, and the two ends of the rotating shaft 56 are rotatably connected to the inside of the cleaning shell 511.

[0018] Specifically: Multiple radially distributed high-speed rotating fan blades 4, combined with an LED array, enhance the three-dimensionality and coverage of the holographic image, strengthening the immersive experience for visitors. Four support rods 52 are distributed at the four corners to form a stable frame, ensuring the support strength of the transparent plastic panel 58 when it is unfolded, making the protection more reliable.

[0019] Furthermore: the transparent plastic sheet 58 is wound around the rotating shaft 56 and automatically wound up and down through the spiral spring 57. The structure is compact and the winding and unwinding process is stable, saving space. The rotating shaft 56 is rotatably connected to the inner wall of the cleaning shell 511 to ensure smooth winding.

[0020] As a further implementation of this solution, each pair of tension springs 54 and hooks 55 are set on the upper inner side of the slide groove 53. The shape of the hooks 55 is adapted to the hanging holes 510. The cleaning shell 511 is a square shell. The cleaning groove 512 and the arc groove 513 are both set on the inner side of the four sides of the cleaning shell 511. The cleaning groove 512 is filled with cleaning agent. There are multiple cleaning blocks 514 and sponge blocks 515. The cleaning blocks 514 and sponge blocks 515 are distributed in a linear array in the arc groove 513. The outer sides of the cleaning blocks 514 and sponge blocks 515 are in close contact with the outer side of the transparent plastic plate 58.

[0021] Specifically: Each groove 53 contains two symmetrical tension springs 54 and hooks 55, which make the support plate 59 evenly stressed and more securely attached. The transparent plastic plate 58 is more stable in the protective state. The hooks 55 and the hanging holes 510 are shaped to match, ensuring convenient attachment and detachment operations and improving the efficiency of state switching. The square cleaning shell 511, together with the cleaning grooves 512 and arc grooves 513 on the inner sides of the four sides, fully covers the cleaning path of the transparent plastic plate 58 and matches the shape of the transparent plastic plate 58 to improve the cleaning fit.

[0022] Furthermore, multiple linear arrays of cleaning blocks 514 and sponge blocks 515 are alternately distributed to increase the contact area with the transparent plastic plate 58, improve cleaning efficiency, and effectively remove stains and dust. The outer sides of the cleaning blocks 514 and sponge blocks 515 are tightly attached to the transparent plastic plate 58 to ensure uniform cleaning pressure.

[0023] Workflow: When the device is not being cleaned, the transparent plastic plate 58 of the protective component 5 is kept in an extended state by the rotating shaft 56 under the preload of the spiral spring 57. The hanging holes 510 at both ends of the support plate 59 are engaged with the hooks 55 in the slide grooves 53 of the support rod 52, and the tension spring 54 is stretched, so that the transparent plastic plate 58 forms a physical fence, providing all-round protection for the high-speed rotating fan blades 4 and preventing tourists from accidentally touching and getting injured. When cleaning of the transparent plastic sheet 58 is required, the operator manually separates the hook 55 in the groove 53 of the support rod 52 from the hanging hole 510 of the support plate 59. At this time, the tension constraint of the tension spring 54 is released. After the hook 55 separates from the hanging hole 510, the rebound force of the spiral spring 57 drives the rotating shaft 56 to rotate, and the transparent plastic sheet 58 begins to wind around the rotating shaft 56. During the winding and retraction process of the transparent plastic sheet 58, its surface will fully contact the cleaning block 514 and sponge block 515 in the arc groove 513. During the pulling process of the transparent plastic sheet 58, the cleaning block 514 and sponge block 515 will roll at different angles, which can... The cleaning solution in the cleaning tank 512 is absorbed and carried to the surface of the transparent plastic plate 58. At the same time, the cleaning block 514 and the sponge block 515 can roll and wipe the stubborn stains on the surface of the transparent plastic plate 58, thus cleaning the transparent plastic plate 58. After cleaning, the operator pulls the support plate 59 to unfold the transparent plastic plate 58 again, so that the hanging hole 510 of the support plate 59 can be hooked again with the hook 55 in the slide groove 53 of the support rod 52. At this time, the tension spring 54 is re-stretched, and the transparent plastic plate 58 forms a protective fence again. The device returns to the normal protective state and continues to provide physical protection for the high-speed rotating fan blade 4, ensuring the safety of tourists during interaction.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
