[0034] In order to illustrate the technical solutions described in the present utility model, the following will be described through specific embodiments, and only the parts related to the embodiments of the present utility model are shown.

[0035] Embodiment:

[0036] As shown in Figures 1 - 3 the figure, the utility model provides a multifunctional holographic display showcase, comprising: a fixed seat 1, a holographic fan 2, an audio structure 3, an auxiliary light strip 4 and a transparent outer cover 5; the holographic fan 2 is arranged on the fixed seat 1 through a mounting bracket 6 and is used for holographically displaying information; the audio structure 3 is arranged in the fixed seat 1 and is used for playing audio; the auxiliary light strip 4 is arranged around the bottom of the fixed seat 1 and is used for emitting light to make the holographic display showcase present a suspended three-dimensional effect; the transparent outer cover 5 is fixedly connected to the fixed seat 1 through a groove 11 on the fixed seat 1 and is used for protecting the holographic fan 2 arranged above the fixed seat 1.

[0037] Specifically, the holographic display showcase described in this embodiment comprises a holographic fan 2, an audio structure 3 and an auxiliary light strip 4. The function of the holographic fan 2 is to be able to holographically display information. The audio structure 3 can play audio. Combined with the holographic fan 2, while the holographic fan 2 holographically displays information, it plays voice information that conforms to the display content of the holographic fan 2. The auxiliary light strip 4 can emit light to make the holographic display showcase present a suspended three-dimensional effect. Its functions are relatively rich, capable of bringing rich visual effects and having a good display effect.

[0038] The holographic display showcase further comprises a transparent outer cover 5. The transparent outer cover 5 is arranged on the groove 11 on the fixed seat 1. The holographic fan 2 is arranged inside the transparent outer cover 5. While being protected by the transparent outer cover 5, it does not affect the display effect of the holographic fan 2. It should be noted that the material of the transparent outer cover 5 is transparent glass or acrylic board, and in this embodiment, it can be selected as ultra-clear transparent glass.

[0039] As an alternative implementation, as shown in Figure 3 the figure, the mounting bracket 6 comprises a mounting rod 61 and a mounting shell 62. One end of the mounting rod 61 is fixedly connected to the fixed seat 1, and the other end is connected to the holographic fan 2; the mounting shell 62 is a structure with one end open and one end closed, forming a groove body for contacting the holographic fan 2 and protecting the internal structure of the holographic fan 2. Specifically, the mounting rod 61 is used to support the holographic fan 2, facilitating the rotation of the holographic fan 2 on the fixed seat 1 and inside the transparent housing to holographically display information. The mounting shell 62 is used to protect the internal structure of the holographic fan 2. It is equivalent to the outer shell of the holographic fan 2, protecting the internal structure of the holographic fan 2 while not affecting the rotation of the holographic fan 2 to display information. And it can block the internal structure of the holographic fan 2 to make the overall structure more beautiful.

[0040] As an alternative implementation, as shown in Figure 3As shown in the figure, the holographic fan 2 includes a driving component 21, a rotating component 22, and a light-emitting component 23. One end of the rotating component 22 is connected to the driving component 21, and the other end is connected to the light-emitting component 23. The rotating component 22 drives the light-emitting component 23 to rotate under the action of the driving component 21, and the light-emitting component 23 holographically displays information during rotation. Specifically, the holographic fan 2, as the most important display component in this embodiment, includes a driving component 21, a rotating component 22, and a light-emitting component 23. When the driving component 21 and the light-emitting component 23 are installed, they will be installed in the installation shell 62 and protected by the installation shell 62. Among them, the driving component 21 is used to drive the rotating component 22 to rotate. The rotating component 22 is fixedly connected to the light-emitting component 23. When the rotating component 22 acts under the action of the driving component 21, it can drive the light-emitting component 23 to rotate synchronously, and the light-emitting component 23 will also emit light during rotation to achieve the effect of holographically displaying information.

[0041] More specifically, as Figures 1 - 3 shown in the figure, the light-emitting component 23 includes at least one fan blade 231, and a plurality of LED lamp beads are arranged on each fan blade 231. When the light-emitting component 23 rotates at a high speed under the action of the rotating component 22, the fan blades 231 will be in an invisible state, but the colors displayed by the plurality of LED lamp beads on the fan blades 231 will change continuously. Using the principle of visual persistence of the human eye, a complete and continuous picture is formed, and a holographic imaging three-dimensional effect is achieved through display, and the display effect is good. In this embodiment, the number of fan blades 231 can be selected according to the actual situation. If the number of fan blades 231 is small, the rotation speed of the driving component 21 needs to be faster. If the number of fan blades 231 is large, the rotation speed of the driving component 21 can be slower, but no matter how it is set, it will not affect the display of information by the light-emitting component 23. In this embodiment, the number of fan blades 231 can be selected as four.

[0042] It should be noted that the information displayed by the holographic fan 2 includes but is not limited to videos and pictures. The application places include but are not limited to museums, the education industry, exhibition halls, shopping malls, etc.

[0043] As an alternative implementation, as Figure 3As shown in the figure, the audio structure 3 includes a power amplifier board 31 and a speaker 32; the power amplifier board 31 is arranged inside the fixed seat 1; the speaker 32 is arranged on the inner side of the fixed seat 1 and corresponds to the playing hole 12 on the side of the fixed seat 1; the speaker 32 is electrically connected to the power amplifier board 31, and the speaker 32 plays audio under the action of the power amplifier board 31. Specifically, the audio structure 3 is arranged in the fixed seat 1 and is used to play audio information corresponding to the information displayed by the holographic fan 2. The audio structure 3 includes a power amplifier board 31 and a speaker 32. The power amplifier board 31 is electrically connected to the speaker 32, and the speaker 32 drives a flat object to resonate through the power amplifier board 31 to emit sound. The speaker 32 is arranged on the inner side of the fixed seat 1, and the corresponding side of the fixed seat 1 is provided with a playing hole 12 to facilitate the sound of the speaker 32 to be emitted outward. It should be noted that the power amplifier board 31 in this embodiment can be selected as a two-channel digital Bluetooth power amplifier board 31, and the speaker 32 can be selected as a resonant speaker 32.

[0044] As an alternative implementation, as Figure 3 shown in the figure, the holographic display showcase further includes a power supply module 7. The power supply module 7 includes a battery 71 and a battery cover 72. The battery 71 is arranged inside the fixed seat 1 through the battery cover 72; the holographic fan 2, the audio structure 3, and the auxiliary light strip 4 are all electrically connected to the battery 71 and are powered by the battery 71. Specifically, the power supply module 7 is used to supply power to the holographic fan 2, the audio structure 3, and the auxiliary light strip 4 to ensure the normal operation of the holographic fan 2, the audio structure 3, and the auxiliary light strip 4. The battery 71 is arranged inside the fixed seat 1 through the battery cover 72, and the battery 71 can also be taken out of the fixed seat 1 under the action of the battery cover 72 to replace the battery 71, and the disassembly and assembly are relatively convenient. It should be noted that the battery 71 in this embodiment can be selected as a lithium battery 71.

[0045] As an alternative implementation, the power supply module 7 further includes a charging interface 13. The charging interface 13 is arranged on the side of the fixed seat 1 and is electrically connected to the battery 71. An external charging device can charge the battery 71 through the charging interface 13. Specifically, the charging interface 13 is also arranged in the power supply module 7 and is electrically connected to the battery 71. An external charging device can charge the battery 71 through the charging interface 13. When it is not convenient to replace the battery 71 during the use of the holographic display showcase, the battery 71 can be directly charged through the charging interface 13 to ensure the normal use of the holographic fan 2, the audio interface, and the auxiliary light strip 4. It should be noted that the charging interface 13 in this embodiment can be selected as a Type-C charging interface 13. On the side of the fixed seat 1, a power level indicator light 19 is also arranged above the charging interface 13 to indicate the remaining power of the battery 71.

[0046] As an alternative implementation, as Figure 3As shown, the holographic display showcase further includes a voltage stabilizing plate 8, which is arranged inside the fixing base 1 and located on the side of the battery 71; the holographic fan 2 and the audio structure 3 are electrically connected to the battery 71 through the voltage stabilizing plate 8, and the voltage stabilizing plate 8 is used to stabilize the voltage output by the battery 71 and supply it to the holographic fan 2 and the audio structure 3 for use. Specifically, the size of the battery 71 is smaller than that of the fixing base 1. After the battery 71 is installed in the fixing base 1, there is a gap between the battery 71 and the fixing base 1, and the voltage stabilizing plate 8 is arranged in this gap, with a relatively compact structure and space saving. The holographic fan 2, the audio structure 3 and the battery 71 are connected through the voltage stabilizing plate 8. In this embodiment, the voltage stabilizing plate 8 is used as a stabilizing device. When the power of the lithium battery 71 drops, the output voltage will also drop, resulting in insufficient power supply, which will affect the display effect of the holographic fan 2 and the sound playback effect of the audio structure 3. Therefore, the voltage stabilizing plate 8 is set to ensure the stable output voltage of the battery 71, and the voltage output by the battery 71 is stabilized and then supplied to the holographic fan 2 and the audio structure 3 for use, which can ensure the stability of the holographic fan 2 and the audio structure 3 during use.

[0047] As an optional implementation manner, a soft light cover plate 14 is arranged at the bottom of the fixing base 1, and the auxiliary light strip 4 is arranged around the bottom of the soft light cover plate 14. Specifically, the transparent light strip is arranged at the bottom of the fixing base 1 through the soft light cover plate 14 and is arranged around the bottom of the fixing base 1. The auxiliary light strip 4 is combined with the soft light cover plate 14. When the auxiliary light strip 4 is turned on, the auxiliary light strip 4 will emit light downward, and the holographic display showcase will present a three-dimensional floating effect, making the holographic display showcase more beautiful and more ornamental. More specifically, the soft light cover plate 14 is a cover plate at the bottom of the fixing base 1. Its functions include not only facilitating the setting of the light strip, but also protecting the structures installed inside the fixing base 1. When the internal structures are damaged, the soft light cover plate 14 can be opened to take out the internal structures for replacement or repair, with a simple structure and convenient disassembly and assembly. It should be noted that the auxiliary light strip 4 in this embodiment can be selected as a soft light strip.

[0048] As an optional implementation, the holographic display showcase further includes a control module. The holographic fan 2, the audio structure 3, and the auxiliary light strip 4 are all connected to the control module. The states of the holographic fan 2, the audio structure 3, the auxiliary light strip 4, and the power supply module 7 are all controlled by the control module; a plurality of control buttons are correspondingly arranged on the fixing base 1. Specifically, the control module is used to control the rotation of the holographic fan 2, control the information display of the holographic fan 2, control the audio structure 3 to play audio, and control the auxiliary light strip 4 to emit light. In addition, the control module is also connected to the power supply module 7 to control the start of the power supply module 7, so that the power supply module 7 supplies power to the holographic fan 2, the audio structure 3, and the auxiliary light strip 4, ensuring the normal use of the holographic fan 2, the audio structure 3, and the auxiliary light strip 4. For the convenience of controlling the holographic display showcase, a control switch knob, a light strip knob, a speaker 32 knob, and a volume adjustment knob 18 are also provided; the control switch button 15, the light strip button 16, the speaker button 17, and the volume adjustment knob 18 are all arranged on the side of the fixing base 1.
