Description

Technical Field

[0001] The present invention relates to the field of multimedia display devices, and in particular to a multimedia integrated display device. Background Art

[0002] As an important carrier of the modern cultural and tourism industry, the multimedia integrated display device provides an innovative solution for the digital display of ancient building cultural heritages in scenic spots by integrating dynamic projection, interactive control, and mechanical transmission technologies. In historical and cultural scenic spots, ancient building sand tables are often used to restore the overall layout, structural features, and historical evolution process of building complexes. Although traditional static sand table models can present the appearance of buildings, they are limited by a single perspective and fixed display mode, and it is difficult to dynamically display building details and create an immersive experience. With the development of multimedia technology, projection mapping technology has been introduced into the field of sand table display. By superimposing virtual images on the surface of physical models, it is possible to dynamically display content such as the disassembly of building structures and the restoration of historical scenes.

[0003] At present, some dynamic display devices cannot centrally present the interactive projection content of different building models at a single display platform position, and tourists need to frequently move the observation points, which affects the viewing coherence. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings that some dynamic display devices in the prior art cannot centrally present different building models at a single display platform position, and to propose a multimedia integrated display device.

[0005] In order to solve the problems existing in the prior art, the present invention adopts the following technical solutions:

[0006] A multimedia integrated display device includes a display cabinet and a display platform fixedly connected to the front opening of the display cabinet. A circular track assembly is provided at the bottom of the inner cavity of the display cabinet. A plurality of placement components are slidably assembled on the circular track assembly at equal intervals. A building model is provided on the top of the placement component. A projection component that can move along the width direction of the display cabinet is provided at the top of the inner cavity of the display cabinet. A linkage component is provided at the bottom of the projection component. The linkage component is used to push the placement component and the projection component to move synchronously to the display area of the display platform.

[0007] Preferably, the circular track assembly includes four sprockets and a chain belt sleeved outside the sprockets. A support platform is fixedly provided at the bottom of the inner cavity of the display cabinet. Four drive motors are fixedly provided on the support platform. The output ends of the four drive motors are fixedly connected to the centers of the sprockets.

[0008] Preferably, the placement component includes a connecting plate. One end of the connecting plate is fixedly connected to the upper surface of the conveyor belt. A moving plate is slidably arranged above the connecting plate. A placement plate is fixedly arranged at the center of the upper surface of the moving plate, and the placement plate is used for installing a building model.

[0009] Preferably, two limiting blocks are fixedly arranged on the upper surface of the connecting plate. A limiting rod is inserted into the two limiting blocks. Both ends of the limiting rod are fixedly connected to both ends of the placement plate, and a spring is sleeved on the limiting rod.

[0010] Preferably, a linear guide rail is fixedly arranged at the top of the inner cavity of the display cabinet. The linear guide rail includes a lead screw, a driving block, and a control motor. The lower end of the driving block is connected to the projection component.

[0011] Preferably, the projection component includes four projectors and a fixing ring. Four adjustable brackets are arranged in a cross shape on the lower surface of the fixing ring.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In the present invention, the annular track component drives the model on the placement component to move below the projection component, and then the projection component drives the placement component below to move through the linkage component, so that the selected ancient building model moves to the display platform position, which is convenient for tourists to observe closely. By switching different ancient building models, the viewing coherence is improved. The projection of the projection component can cover the surface of the building model. Through the light and shadow changes and dynamic effects, the spatial sense of hierarchy is enhanced. Combined with the sound effects (such as environmental sounds, commentaries) and dynamic pictures (such as day and night switching), the visiting tourists can feel on the scene.

[0016] 2.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Embodiment: This embodiment provides a multimedia integrated display device. Refer to Figures 1-5 , specifically, it includes a display cabinet 1 and a display stand 11 fixedly connected to the front opening of the display cabinet 1. The bottom of the inner cavity of the display cabinet 1 is provided with an annular track assembly 2, and a plurality of placement assemblies 3 evenly distributed at equal intervals are slidably assembled on the annular track assembly 2. A building model is provided on the top of the placement assembly 3. The top of the inner cavity of the display cabinet 1 is provided with a projection assembly 6 that can move along the width direction of the display cabinet 1. A linkage assembly 8 is provided at the bottom of the projection assembly 6. The linkage assembly 8 is used to push the placement assembly 3 to move synchronously with the projection assembly 6 to the display area of the display stand 11.

[0026] In this embodiment, the ancient buildings in the scenic area are installed on the placement component 3 in a certain proportion in sequence. The ancient buildings use matte white materials (such as acrylic and gypsum) to avoid the influence of reflection on the projection effect. The digital model is imported into the projection component 6, and the calibration points identical to the physical building model are marked at the corresponding positions to establish the mapping relationship between virtual and reality. When tourists need to know about a certain ancient building, through software control, the annular track component 2 drives the model on the placement component 3 to move under the projection component 6. Then, the projection component 6 drives the placement component 3 below through the linkage component 8 to move to the position of the display stand 11, which is convenient for tourists to watch. By switching different ancient building models, the viewing coherence is improved. The projection of the projection component 6 can cover the surface of the building model. Through the light and shadow changes and dynamic effects, the spatial sense of hierarchy is enhanced. Combined with the sound effects (such as environmental sounds and explanations) and dynamic pictures (such as day and night switching), the visiting tourists can feel on the scene.

[0027] In the specific implementation process, as Figure 1 and Figure 2 shown, the annular track component 2 includes four sprockets 23 and a chain belt 22 sleeved outside the sprockets 23. A support platform 21 is fixedly arranged at the bottom of the inner cavity of the display cabinet 1, and four driving motors 24 are fixedly arranged on the support platform 21. The output ends of the four driving motors 24 are fixedly connected to the centers of the sprockets 23.

[0028] In this embodiment, through the synchronous operation of the four driving motors 24, the sprockets 23 are driven to rotate in the same direction. The sprockets 23 drive the chain belt 22 to move, and the chain belt 22 drives the placement component 3 to move synchronously, so that the required ancient building model can move under the projection component 6, realizing the rapid switching of the ancient building model.

[0029] In the specific implementation process, as Figure 1 、 Figure 2 and Figure 3 shown, the placement component 3 includes a connecting plate 31. One end of the connecting plate 31 is fixedly connected to the upper surface of the chain belt 22. A moving plate 32 is slidably arranged above the connecting plate 31. The center of the upper surface of the moving plate 32 is fixedly provided with a placement plate 33 for installing the building model. An annular slide rail 5 is fixedly arranged on the upper surface of the support platform 21, and a plurality of sliders 51 are arranged on the annular slide rail 5. The lower surface of the connecting plate 31 is fixedly connected to the sliders 51.

[0030] In this embodiment, the placement component 3 is divided into three layers. The lowermost connecting plate 31 is driven by the chain belt 22 and moves along the specified route on the annular slide rail 5 through the sliders 51. The annular slide rail 5 has the same shape as the chain belt 22. The middle moving plate 32 can move horizontally along the connecting plate 31, which is convenient for driving the ancient building model to move to the position of the display stand 11. The uppermost placement plate 33 is used to fix the ancient building model.

[0031] In the specific implementation process, asFigure 1 , Figure 2 and Figure 3 As shown in Figure 3 , two limit blocks 4 are fixedly arranged on the upper surface of the connecting plate 31. A limit rod 41 is inserted into the two limit blocks 4. Both ends of the limit rod 41 are fixedly connected to both ends of the placing plate 33. A spring 42 is sleeved on the limit rod 41.

[0032] In this embodiment, the moving plate 32 moves along the limit block 4 through the limit rod 41, providing stability for the moving plate 32. When the moving plate 32 returns, it is reset by the spring 42.

[0033] In the specific implementation process, as Figure 1 , Figure 2 and Figure 4 shown, a linear guide rail 7 is fixedly arranged at the top of the inner cavity of the display cabinet 1. The linear guide rail 7 includes a lead screw 71, a driving block 72 and a control motor 73. The lower end of the driving block 72 is connected to the projection assembly 6.

[0034] In this embodiment, the control motor 73 drives the lead screw 71 to rotate. The lead screw 71 drives the driving block 72 to move horizontally. The driving block 72 then drives the projection assembly 6 to move, so that the projection assembly 6 moves above the display table 11 and is parallel to the ancient building model.

[0035] In the specific implementation process, as Figure 1 , Figure 2 and Figure 4 shown, the projection assembly 6 includes four projectors 63 and a fixing ring 61. Four adjustable-angle brackets 62 are arranged in a cross shape on the lower surface of the fixing ring 61. The projectors 63 are fixedly arranged on the brackets 62. The middle part of the upper surface of the fixing ring 61 is fixedly connected to the slider 51.

[0036] In this embodiment, four projectors 63 are arranged to project the ancient building model in all directions, reducing occlusion and distortion. The angle of each projector 63 can be adjusted through the bracket 62. When the driving block 72 moves, it will drive the fixing ring 61 and the four projectors 63 below to move synchronously.

[0037] In the specific implementation process, as Figure 1 , Figure 2 and Figure 5 shown, the linkage assembly 8 includes a connecting rod 81 and a positioning plate 83. One end of the connecting rod 81 is fixedly connected to the edge of the fixing ring 61. The positioning plate 83 is fixedly connected to the edge of the upper surface of the connecting plate 31. A positioning groove 84 is opened at one end of the positioning plate 83. A positioning shaft 82 is fixedly arranged at the end of the connecting rod 81 away from the fixing ring 61.

[0038] In this embodiment, the movement of the fixed ring 61 drives the connecting rod 81 to move. The positioning shaft 82 at the end of the connecting rod 81 enters the positioning groove 84. The opening of the positioning groove 84 is in a shape of an inverted V, and the inner part of the positioning groove 84 fits with the outer wall of the positioning shaft 82, enabling the positioning shaft 82 to accurately enter the inner part of the positioning groove 84. Through the positioning groove 84, the position of the placement component 3 can be parallel to the position of the projection component 6, achieving accurate positioning of the placement component 3 and making the projection more accurate. The moving plate 32 moves along the connecting plate 31 through the connecting rod 81 and the positioning plate 83, moving the ancient building model to the position of the display platform 11.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
