Bevel gear a meshes with gear b, which is mounted on the rotating shaft. Bevel gear a meshes with bevel gear b, and bevel gear b and bevel gear c are respectively mounted at both ends of mounting shaft b. When the transparent cover moves to the bottom of the cleaning height zone, bevel gear c meshes with bevel gear d. Bevel gear d and pulley a are coaxially mounted on mounting shaft c. Pulley a is connected to pulley b via a belt. Pulley b and the fan blade mechanism are coaxially mounted on mounting shaft d.

[0016] On the other hand, the present invention proposes a display method for the above-mentioned three-dimensional animation display system, comprising the following steps:

[0017] S1. When the transparent cover is within the display height area, the height of the transparent cover can be adjusted through the lifting mechanism to display it to users of different heights.

This effectively ensures the light transmission of the transparent cover, allowing users to view the 3D holographic animation displayed on the inner holographic screen more clearly.

[0027] Example 1

[0028] like Figures 1-4 As shown in the figure, the three-dimensional animation display system proposed in this embodiment includes a display component, a blower cleaning component, and a support cover 38.

[0029] The display components include a transparent cover 1, a mounting platform 2, a mounting cover 3, and a holographic display screen. Both the transparent cover 1 and the holographic display screen are mounted on top of the mounting platform 2, with the holographic display screen located inside the transparent cover 1. The holographic display screen uses an existing display and can display three-dimensional holographic images. Users view the inner holographic images through the transparent cover 1. The mounting platform 2 is located on top of the mounting cover 3, which houses a speaker assembly. The outer perimeter of the mounting cover 3 is evenly distributed with through holes for the speaker assembly to emit sound.

[0030] The air-blowing cleaning assembly includes a fan blade mechanism 23 and an air outlet assembly. The fan blade mechanism 23 faces the air outlet assembly and blows air onto the air outlet assembly. Finally, the air can be discharged from the air outlet assembly and blow away the dust accumulated on the transparent cover 1.

[0031] The support cover 38 is equipped with a lifting mechanism for driving the installation cover 3 to rise and fall, and a transmission mechanism for driving the air outlet component to rise and fall. The vertical moving area of ​​the transparent cover 1 is divided into a display height area and a cleaning height area from top to bottom. When the transparent cover 1 rises and falls in the display height area, the air outlet component is located at the top of the support cover 38. When the transparent cover 1 rises and falls in the cleaning height area, the air outlet component moves in the opposite direction to the transparent cover 1.

[0032] The lifting mechanism includes a rotating shaft 8, a lifting frame 34, a motor a35, a screw 36, and a guide rod 37. The rotating shaft 8 is vertically mounted on the lifting frame 34, and its top end is connected to the mounting cover 3. The lifting frame 34 is threadedly connected to the screw 36 and slidably mounted on the guide rod 37. The motor a35 is housed inside a support cover 38 and is driven by the screw 36. Both the screw 36 and the guide rod 37 are vertically mounted inside the support cover 38. The motor a35 drives the screw 36 to rotate, which in turn drives the lifting frame 34 to move up and down. The guide rod 37 guides the direction of lifting.

[0033] The presentation method of the above-mentioned 3D animation display system includes the following steps:

[0034] S1. When the transparent cover 1 is within the display height area, the height of the transparent cover 1 can be adjusted through the lifting mechanism to display it to users of different heights.

[0035] S2. When not used for display, the transparent cover 1 is adjusted downward to the cleaning height area by the lifting mechanism, and the fan blade mechanism 23 is used to fan the air to supply air to the air outlet component. The air flows out from the air outlet component and blows onto the surface of the transparent cover 1 for dust removal.

[0036] This embodiment saves labor and time by blowing away accumulated dust on the transparent cover 1 when not in use. During display, the height of the transparent cover 1 is adjusted within the display height zone using a lifting mechanism to accommodate users of different heights viewing the 3D holographic animation. When not in use, the transparent cover 1 is lowered to the cleaning height zone using the lifting mechanism, and the fan blade mechanism 23 rotates to blow air onto the air outlet component. The airflow from the air outlet component acts on the outer surface of the transparent cover 1, blowing away accumulated dust and cleaning the transparent cover 1. This method is highly efficient and effective, ensuring the light transmission of the transparent cover 1 and allowing users to view the 3D holographic animation displayed on the holographic screen inside more clearly.

[0037] Example 2

[0038] like Figures 1-4As shown, this embodiment proposes a three-dimensional animation display system. Compared to Embodiment 1, in this embodiment, the rotating shaft 8 is rotatably mounted on the lifting frame 34. The lifting frame 34 is equipped with a drive mechanism for driving the rotating shaft 8 to rotate alone or simultaneously driving the rotating shaft 8 and the fan blade mechanism 23 to rotate. The drive mechanism includes a motor b9, a mounting shaft a10, gears a11, b12, bevel gears a13, b14, a mounting shaft b15, c16, d17, a mounting shaft c18, pulley a19, belt 20, pulley b21, a mounting shaft d22, and a support frame 24. Both the motor b9 and the support frame 24 are mounted on the lifting frame 34. The motor b9 is driven by the mounting shaft a10, and the gears a11 and b13 are driven by the fan blade mechanism 23. The gears are coaxially mounted on the mounting shaft a10, gear a11 meshes with gear b12, gear b12 is mounted on the rotating shaft 8, bevel gear a13 meshes with bevel gear b14, and bevel gear b14 and bevel gear c16 are respectively mounted at both ends of the mounting shaft b15; when the transparent cover 1 moves to the bottom of the cleaning height area, bevel gear c16 meshes with bevel gear d17, bevel gear d17 and pulley a19 are coaxially mounted on the mounting shaft c18, pulley a19 is connected to pulley b21 through belt 20, and pulley b21 and fan blade mechanism 23 are coaxially mounted on the mounting shaft d22; both mounting shafts a10 and b15 are rotatably mounted on the support frame 24, and both mounting shafts c18 and d22 are rotatably mounted on the support cover 38.

[0039] When the transparent cover 1 is raised and lowered within the display height area, the motor b9 can drive the mounting shaft a10 to rotate. The mounting shaft a10 drives the rotating shaft 8 to rotate through gears a11 and b12. The rotating shaft 8 drives the mounting cover 3 to rotate, so as to adjust the display position of the three-dimensional holographic image and make it convenient for users in different positions to view it.

[0040] When the transparent cover 1 descends to the bottom of the cleaning height zone, the bevel gear c16 moves to the position where it meshes with the bevel gear d17. At this time, the motor b9 runs, which not only enables the rotation of the mounting cover 3, but also drives the fan blade mechanism 23 to rotate through the mounting shaft c18, pulley a19, belt 20, pulley b21 and mounting shaft d22. The fan blade mechanism 23 supplies air to the air outlet assembly, which facilitates subsequent dust blowing and cleaning.

[0041] like Figure 2 and Figure 3 As shown, the air outlet assembly includes a lifting cylinder 27, a sliding rod 271, and an air outlet pipe 28. The lifting cylinder 27 is vertically arranged and its top end is connected to the air outlet pipe 28. The sliding rod 271 is vertically arranged at the bottom of the air outlet pipe 28 and is slidably arranged on the support cover 38. The air outlet pipe 28 is a circular pipe located on the outer periphery of the transparent cover 1. Air outlet holes are evenly arranged on the inner side surface of the air outlet pipe 28. The top of the support cover 38 is provided with a storage groove 381 for the air outlet pipe 28 to be received.

[0042] The sliding rod 271 in the air outlet assembly can slide on the support cover 38. The lifting cylinder 27 can be driven to rise through the transmission mechanism and will fall freely when not driven. The lifting cylinder 27 can guide the air blown by the fan blade mechanism 23 into the air outlet pipe 28 and blow it to the outer surface of the transparent cover 1 through the air outlet hole. When the air outlet pipe 28 is not used for cleaning, the air outlet pipe 28 falls freely into the storage slot 381.

[0043] like Figure 3 As shown, a sliding cylinder 26 is slidably sleeved on the lifting cylinder 27, and an air guide duct 25 is slidably sleeved on the sliding cylinder 26. A bracket 251 is provided on the air guide duct 25, and the bracket 251 is set on the inner wall of the support cover 38. The fan blade mechanism 23 faces the air guide duct 25. Multiple sliding cylinders 26 can be provided. When the lifting cylinder 27 rises, it can drive the sliding cylinders 26 to rise, but it can still ensure the connection between the air guide duct 25, the sliding cylinder 26 and the channel inside the lifting cylinder 27, which facilitates air guidance.

[0044] like Figure 3 As shown, the transmission mechanism includes a rotating sleeve 29, a connecting ring a30, a connecting rope 31, a guide wheel 32, and a connecting ring b33. The rotating sleeve 29 is rotatably mounted on the rotating shaft 8, and the connecting ring a30 is mounted on the rotating sleeve 29. The two ends of the connecting rope 31 are connected to the connecting ring a30 and the connecting ring b33, respectively. The connecting rope 31 passes around the guide wheel 32 and is distributed in an inverted V shape. The guide wheel 32 is rotatably mounted inside the support cover 38, and the connecting ring b33 is mounted on the lifting cylinder 27. When the transparent cover 1 moves from the display height area to the cleaning height area, the connecting rope 31 is tightened. The rotating sleeve 29 and the connecting ring a30 descend with the descent of the rotating shaft 8. The connecting ring a30 drives the connecting ring b33 to rise through the connecting rope 31. The guide wheel 32 acts as a guide, causing the connecting ring b33 to move in the opposite direction to the connecting ring a30. The connecting ring b33 drives the lifting cylinder 27 to rise, and the lifting cylinder 27 drives the air outlet pipe 28 to rise, moving it to the periphery of the transparent cover 1, ready for subsequent blowing and dust removal treatment.

[0045] Example 3

[0046] This embodiment presents a 3D animation display system. Compared to Embodiment 1, this embodiment, as follows: Figure 5 As shown, the internal space of the mounting cover 3 is evenly divided into three movable sectors on the projection plane. Each movable sector is equipped with a set of speaker components. The speaker components include a motor 4, a rotating rod 5, a connecting rod 6, and a speaker 7. The motor 4 is located inside the mounting cover 3 and is driven by the rotating rod 5. The connecting rod 6 is located on the rotating rod 5, and the speaker 7 is located at the outer end of the connecting rod 6, facing the through hole to transmit sound outward.

[0047] The 3D animation display system also includes an animation sound direction recognition module and a controller. The animation sound direction recognition module is connected to the controller, and the controller is connected to the motor 4 for control.

[0048] In this embodiment, when the 3D holographic image needs to emit sound, the desired sound location recognition module identifies the sound location and sends the recognition data to the controller. The controller then controls the motor 4 in the speaker assembly based on the recognition data. The motor 4 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the speaker 7 to rotate to the corresponding location to emit sound through the connecting rod 6, thus achieving a more realistic simulated sound and providing users with a more lifelike sound effect. Each speaker assembly is responsible for emitting sound in its respective sector. That is, when the desired sound location recognition module identifies the sound location as being within the active sector of the corresponding speaker assembly, that speaker assembly is used to emit sound.

[0049] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
