The mounting plate 41 can be used to fix electrical components and space them away from the light box assembly 3 to ensure heat dissipation. This spacing also prevents the outer frame assembly 1 from overheating. The first heat dissipation hole on the first connecting plate 42 enhances the heat dissipation of the installation space and increases the strength of the first connecting plate 42. Similarly, the second heat dissipation hole on the second connecting plate 43 enhances both the heat dissipation of the installation space and the strength of the second connecting plate 43.

[0077] In one embodiment, the holographic device further includes a heat dissipation structure 5, which is installed at the rear top of the outer frame assembly 1; the rear top of the outer frame assembly 1 is provided with an air outlet, and the bottom of the outer frame assembly 1 is provided with a plurality of air inlets.

[0078] The heat dissipation structure 5 drives the gas flow in the mounting cavity, causing external gas to enter the mounting cavity from the bottom of the outer frame assembly 1. After passing through the light box assembly 3 in the mounting cavity and dissipating and cooling the light box assembly 3, the gas is discharged from the air outlet under the drive of the heat dissipation structure 5, thus achieving the purpose of heat dissipation.

[0079] In a specific implementation, the heat dissipation structure 5 is a heat dissipation fan structure, including at least two, and the at least two heat dissipation structures 5 are spaced apart at the rear top of the outer frame assembly 1.

[0081] Both the voice input structure 6 and the voice output structure 7 are communicatively connected to the electrical components of the electrical assembly 4. The voice input structure 6 receives external voice signals and transmits them to the electrical components, while the voice output structure 7 receives instructions from the electrical components and outputs them to the outside of the holographic device. The holographic device achieves human-computer interaction through the voice input structure 6 and the voice output structure 7. The first through-hole facilitates both heat dissipation of the voice input structure 6 and its acquisition of external voice information; the second through-hole facilitates both heat dissipation of the voice output structure 7 and its voice output. The voice input structure 6 and the voice output structure 7 are respectively located on both sides of the outer frame assembly 1 to avoid mutual interference.

[0082] The voice input structure 6 includes a microphone; the voice output structure 7 includes a speaker.

[0083] In one embodiment, the display assembly 2 includes a display frame 21, a fixing frame 22, and a display screen 23; the display frame 21 is detachably connected to the front of the outer frame assembly 1 and covers the first opening 11; the fixing frame 22 is detachably connected to the rear end of the display frame 21, and the shape of the fixing frame 22 matches the shape of the display frame 21; the display screen 23 is disposed at the rear end of the display frame 21, and the display screen 23 is fixedly clamped between the display frame 21 and the fixing frame 22.

[0084] The display screen 23 is detachably connected to the display frame 21 via the fixing frame 22, which reduces the difficulty of disassembling and assembling the display device, thereby improving the efficiency of disassembling and assembling the display device and facilitating the disassembly and assembly of the display device. Furthermore, by fixing the display screen 23 with the fixing frame 22, the connection stability of the display device can be guaranteed, avoiding connection failure over time and preventing the display screen 23 from falling off due to connection failure.
