Description

Technical Field

[0001] This invention relates to the field of giant screen displays, and more particularly to a linked giant screen that is easy to install and disassemble. Background Technology

[0002] In modern immersive media display and viewing environments, the overall layout combining the giant screens on the left and right sides with the giant screen at the bottom, forming a panoramic interconnected giant screen, has become a core technological means to enhance visual impact and immersion. The biggest advantage of this layout is the significant improvement in visual coverage, where the audience's field of vision is completely enveloped in the picture, creating a stronger sense of immersion and presence during the viewing experience, allowing the audience to feel as if they are actually there. This multi-screen interconnected design makes the form of image presentation more flexible. When content creators need to display specific scenes, such as panoramic aerial photography, overhead views, or science fiction scenes that require large-angle parallax, they need to adjust the angle and resolution ratio between the left and right giant screens to achieve geometric deformation of the image or dynamic transformation of the perspective. Since the left and right screens are usually independent physical modules, when angle calibration, maintenance, or replacement is required, the screens must be disassembled. This process is relatively cumbersome and time-consuming, usually requiring a professional technical team for hoisting and docking, resulting in high maintenance costs. In addition, frequent disassembly and reinstallation may also increase the risk of damage to the screen structure. Summary of the Invention

[0003] To overcome the drawbacks of traditional panoramic linked giant screens, where the left and right giant screens are usually independent physical modules, and the angle adjustment of the left and right giant screens requires cumbersome disassembly, installation, and debugging, while increasing the risk of screen damage, this invention provides a linked giant screen that is easy to install and disassemble.

[0004] The technical solution of this invention provides a linkage giant screen that is easy to install and disassemble, comprising a base, a rear support, a central column, a movable plate, an arc-shaped electric slider, a fixing block, a bottom giant screen, side giant screens, a central curved screen, a laser rangefinder, an air curtain machine, an air curtain pipe, and an adjustment motor; the rear support is fixedly connected to the middle of the rear side of the base; the central column is fixedly connected to the rear support; a movable plate is rotatably connected to the left and right sides of the central column, and the rotation axis of the movable plate coincides with the axis of the central column; an arc-shaped electric slider is slidably connected to the left and right sides of the base; the arc-shaped electric slider is provided with a fixing block connecting the movable plate on the same side; the bottom giant screen is detachably slidably connected to the base. The screen at the bottom is made of high-hardness glass. A side screen is detachably and slidably connected to the front of the movable panel, and the intersection line of the extended side screens coincides with the axis of the central column. A central curved screen is installed on the front of the central column, positioned between the two side screens. A laser rangefinder is installed on the side of the movable panel away from the central column, illuminating the side screens on different sides. An air curtain machine is installed on the movable panel. An air curtain pipe is rotatably connected to the air curtain machine, and the air curtain pipe is connected to the air curtain machine on the same side. Several air vents are provided on the air curtain pipe. An adjusting motor is installed on the air curtain machine to adjust the vertical rotation angle of the air curtain pipe on the same side.

[0005] Furthermore, the bottom giant screen has a first curved edge structure on the front side; the side giant screen has a second curved edge on the bottom front side.

[0006] Furthermore, a blower-suction fan is installed at the rear bottom of the movable plate; the front of the blower-suction fan is connected to several air inlet structures.

[0007] Furthermore, a bubble machine is installed on the air curtain machine; several bubble outlet pipes are connected to the front of the bubble machine.

[0008] The present invention provides a linkage giant screen that is easy to install and disassemble. It consists of a bottom giant screen and two side giant screens, together with a central curved screen located between the two side giant screens to form a ring-shaped linkage giant screen. By pulling the fixed block with an arc-shaped electric slider, the side giant screens on the movable plate are rotated around the axis of the central column, thereby realizing automatic adjustment of the included angle between the two side giant screens.

[0009] In its normal state, the two side giant screens are in a wide-angle unfolded position. The two side giant screens, together with the entire bottom giant screen and the entire central curved screen, can present naked-eye 3D visual images to viewers facing forward. Staff members indicate that viewers should stand in front of the bottom giant screen so that they can enjoy naked-eye 3D visual viewing from a suitable angle. Since multiple giant screens playing simultaneously will generate a large amount of heat accumulation, the air curtain machine continuously blows cool air downwards along the surface of each side giant screen through the air outlet of the air curtain pipe. At the same time, the blower-suction fan performs air suction through the air outlet in the gap structure between the bottom of the side giant screen and the bottom giant screen, sucking the cool air blown downwards to the surface of the bottom giant screen backwards. This prevents the continuously blown cool air from flowing along the front of the bottom giant screen surface towards the viewers, thus achieving heat dissipation for the bottom and side giant screens and reducing the impact of the cool airflow on the viewers' physical sensation.

[0010] When non-glasses-free 3D immersive visual content is required, the two side giant screens display the planar images located on the left and right sides respectively, while the central curved screen displays the supplementary image missing between the two side giant screens. The bottom giant screen displays the planar image located at the bottom. Staff members instruct viewers to stand on the bottom giant screen for a close-up immersive viewing experience. At this time, the angle between the two side giant screens can be changed by pulling the corresponding movable plate using two curved electric sliders, depending on the content being played. For example, when displaying expansive views such as grasslands or seascapes, the two side giant screens are in a large-angle unfolded state. At this time, the two giant side screens are positioned far in front of the viewer, displaying a wide-angle view and allowing the viewer to clearly feel the open space in front of them. When playing narrow view scenes such as alleyways or indoor spaces, the two giant side screens are in a slightly converging position. At this time, the distance between the two giant side screens and the viewer is closer, allowing the viewer to clearly feel that the space has become significantly more cramped, simulating the sense of urgency in a small indoor space. By adjusting the angle between the two giant side screens according to the content being played, the viewer's close-up immersive viewing experience is enhanced.

[0011] When viewers stand on the bottom giant screen for a close-up immersive viewing experience, staff must consistently remind them not to stand within the rotating range of the two side giant screens. This is done as the two curved electric sliders pull the corresponding movable plates to reduce the angle between the two side giant screens. If the laser rangefinder detects viewers lingering within the rotating range of the side giant screens, the curved electric sliders should temporarily stop all rotation of the side giant screens towards the viewers to prevent injury during the rotation. Simultaneously, the motor should be adjusted to rotate the air curtain tubes to allow... The air vents are directed towards lingering viewers, and the bubble machine continuously emits bubbles downwards through the bubble tube. The cold airflow blowing from the air vents propels the bubbles toward the viewers, driving them away from the side giant screen. At the same time, the side giant screen issues a warning to the viewers through the displayed image. Staff guide the viewers away from the rotating range of the side giant screen and to stand in the correct viewing position. Only when the laser rangefinder detects that the lingering viewers have safely moved away from the side giant screen can the curved electric slider resume its action of pulling the side giant screen on the movable plate toward the viewers.

[0012] Furthermore, the movable plate has a slot structure that is compatible with the structure of the fixed block; the fixed block is inserted into the slot on the movable plate on the same side.

[0013] Furthermore, the fixed block is slidably connected to the arc-shaped electric slider on the same side; a spring-type damping telescopic rod is installed on the arc-shaped electric slider; the telescopic ends of the spring-type damping telescopic rod are respectively fixed to the fixed block on the same side.

[0014] Furthermore, a pressure sensor is installed at one end of the fixing block of the spring-dampened telescopic rod.

[0015] Furthermore, several shock-absorbing pads are fixed to the upper side of the base; the shock-absorbing pads are clamped between the base and the bottom giant screen.

[0016] Furthermore, the base is designed with a fan-shaped cross-section when viewed from above, and the front side of the base is designed with an arc-shaped structure with a radius length that is the same as the length of the long side structure of the giant screen on the side.

[0017] Furthermore, several warning spotlights are installed on the front curved surface of the base.

[0018] This invention discloses a modular giant screen that is easy to install and disassemble. It comprises a bottom giant screen and two adjustable side giant screens, which, together with a central curved screen, form a panoramic modular giant screen. The angle between the two side giant screens can be automatically adjusted according to different playback content. Both the bottom and side giant screens are detachable and slidingly connected, facilitating quick disassembly and maintenance. When a laser rangefinder detects a viewer approaching a side giant screen, airflow from an air curtain machine and bubbles from a bubble machine, combined with the display on the side giant screens, warn the approaching viewer, preventing injury from the side giant screens being adjusted. This invention not only solves the technical problem that the left and right giant screens of a panoramic modular giant screen are usually independent physical modules, requiring cumbersome disassembly, installation, and debugging for angle adjustment, and increasing the risk of screen damage, but also allows for arbitrary switching of the angles of the left and right side giant screens during close-range immersive playback, and can also switch to long-distance naked-eye 3D playback.

Detailed Implementation

[0021] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0022] Example 1: A linked giant screen that is easy to install and disassemble, such as... Figures 1-7As shown, the system includes a base 11, a rear support 12, a central column 13, a movable plate 14, an arc-shaped electric slider 15, a fixed block 16, a bottom giant screen 2, a side giant screen 3, a central curved screen 4, a laser rangefinder 51, an air curtain machine 61, an air curtain pipe 62, and an adjusting motor 63. The rear support 12 is fixedly connected to the middle of the rear side of the base 11. The central column 13 is fixedly connected to the rear support 12. A movable plate 14 is rotatably connected to the left and right sides of the central column 13, and the rotation axis of the movable plate 14 is aligned with the center. The axis lines of the columns 13 coincide; an arc-shaped electric slider 15 is slidably connected to the left and right sides of the base 11; each of the two arc-shaped electric sliders 15 is equipped with a fixing block 16; the two fixing blocks 16 are respectively fixed to the movable plate 14 on the same side; a bottom giant screen 2 is detachably slidably connected to the base 11. The surface of the bottom giant screen 2 is made of high-hardness glass to prevent the soles of the shoes of the viewers from scratching the surface of the bottom giant screen 2. The surface of the bottom giant screen 2 is coated with a transparent anti-slip coating to prevent slippage. Viewers experienced accidental slips on the surface of the bottom giant screen 2; each of the two movable plates 14 is detachably and slidably connected to a side giant screen 3, and the intersection line of the extended side giant screens 3 coincides with the axis of the central column 13; a central curved screen 4 is installed on the front side of the central column 13, and the central curved screen 4 is located between the two side giant screens 3; two laser rangefinders 51 are installed on the side of each of the two movable plates 14 away from the central column 13, and the laser rangefinders 51 are directed towards the side giant screens located on different sides. The screen 3 provides illumination from the direction of the screen; each of the two movable plates 14 is equipped with an air curtain machine 61; each of the two air curtain machines 61 is rotatably connected to an air curtain pipe 62, and the air curtain pipe 62 is connected to the air curtain machine 61 on the same side; each of the two air curtain pipes 62 has several air outlets 6201, and the air outlets 6201 are initially inclined downwards towards the side screen 3 on the same side; each of the two air curtain machines 61 is equipped with an adjustment motor 63; the output shafts of the two adjustment motors 63 are respectively fixed to the air curtain pipes 62 on the same side.

[0023] like Figure 5 As shown, the front side of the bottom giant screen 2 is provided with a first curved edge 201 structure to enhance the immersive effect of the image displayed on the front side of the bottom giant screen 2; the bottom front side of each of the two side giant screens 3 is provided with a second curved edge 301, and the image light illuminating the second curved edge 301 provides a transition display area for the gap structure between the bottom of the side giant screen 3 and the bottom giant screen 2, making it less likely for viewers to notice the gap structure between the bottom of the side giant screen 3 and the bottom giant screen 2.

[0024] like Figure 3 , Figures 5-7As shown, each of the two movable plates 14 has a blower 71 installed on its bottom rear side; each of the two blowers 71 has several air outlets 7101 connected to its front side, and the air outlets 7101 are aligned with the gap between the side giant screen 3 and the bottom giant screen 2 on the same side; each of the two air curtain machines 61 has a bubble machine 81 installed on its front side; each of the two bubble machines 81 has several vertically downward bubble outlet pipes 82 connected to its front side, and the bubble outlet pipes 82 are located above the air outlets 6201 of the air curtain machine 61 on the same side.

[0025] This embodiment of a linkage giant screen that is easy to install and disassemble consists of a bottom giant screen 2 and two side giant screens 3, together with a central curved screen 4 located between the two side giant screens 3 to form a ring-shaped linkage giant screen. By pulling the fixed block 16 through the arc-shaped electric slider 15, the side giant screens 3 on the movable plate 14 are rotated around the axis of the central column 13, so as to automatically adjust the included angle between the two side giant screens 3.

[0026] Under normal conditions, such as Figure 1 As shown, the two side giant screens 3 are in a large-angle unfolded state at this time. The two side giant screens 3, together with the entire bottom giant screen 2 and the entire central curved screen 4, can present naked-eye 3D visual images to the viewers in front. The staff indicates that the viewers stand in front of the bottom giant screen 2. The viewers can watch the naked-eye 3D visual images from a distance at a suitable angle. Since the simultaneous playback of multiple giant screens will generate a large amount of heat accumulation, at the same time, the air curtain machine 61 continuously blows cold air downwards along the surface of each side giant screen 3 through the air outlet 6201 of the air curtain pipe 62. At the same time, the blower-suction fan 71 performs air suction in the gap structure between the bottom of the side giant screen 3 and the bottom giant screen 2 through the air outlet 7101, and sucks the cold air blown downwards to the surface of the bottom giant screen 2 backwards, so as to prevent the cold air blown downwards from flowing along the front side of the surface of the bottom giant screen 2 to the viewers. This achieves heat dissipation for the bottom giant screen 2 and the side giant screen 3, and at the same time reduces the impact of the cold air flow on the viewers' physical sensation.

[0027] When immersive visual content that is not naked-eye 3D needs to be played, the two side giant screens 3 display planar images located on the left and right sides respectively, the central curved screen 4 displays supplementary images missing between the two side giant screens 3, and the bottom giant screen 2 displays planar images located on the lower side. Staff members instruct viewers to stand on the bottom giant screen 2 for close-up immersive viewing. At this time, the angle between the two side giant screens 3 can be changed by pulling the corresponding movable plate 14 using two curved electric sliders 15, depending on the content being played. For example, when playing expansive views such as grasslands or seascapes... Figure 1As shown, the two side giant screens 3 are in a wide-angle unfolded state. At this time, the two side giant screens 3 are located in front of the viewer, away from the viewer, to display a wide-angle picture, allowing the viewer to clearly feel that there is an open field of vision in front of them. When playing narrow field of vision such as alleyways or indoors, such as... Figure 10 As shown, the two side giant screens 3 are in a slightly folded-in state. At this time, the distance between the two side giant screens 3 and the viewer is relatively close, allowing the viewer to clearly feel that the space has become significantly cramped, simulating the sense of urgency in a small indoor space. By adjusting the angle between the two side giant screens 3 according to the content being played, the viewer's close-up immersive viewing experience is enhanced.

[0028] When viewers stand on the bottom giant screen 2 for close-up immersive viewing, staff must consistently remind them not to stand within the rotating range of the two side giant screens 3. During the process of the two curved electric sliders 15 pulling the corresponding movable plates 14 to reduce the angle between the two side giant screens 3, if the laser rangefinder 51 detects viewers lingering within the rotating range of the side giant screens 3, the curved electric sliders 15 should temporarily stop all rotation of the side giant screens 3 towards the viewers to prevent injury during the rotation. Simultaneously, the motor 63 should be adjusted to rotate the air curtain duct 62 to allow for... The vent 6201 faces the lingering viewers, and the bubble machine 81 continuously emits bubbles downwards through the bubble outlet pipe 82. The cold airflow blown from the vent 6201 blows the bubbles toward the viewers, driving them away from the side giant screen 3. At the same time, the side giant screen 3 issues a warning to the viewers through the displayed image. Staff guide the viewers away from the rotating range of the side giant screen 3 and to stand in the correct viewing position. Only when the laser rangefinder 51 detects that the lingering viewers have safely moved away from the side giant screen 3 can the arc-shaped electric slider 15 resume its action of pulling the side giant screen 3 on the movable plate 14 to rotate toward the viewers.

[0029] Example 2, based on Example 1 above, as follows: Figures 1-9As shown, in this embodiment, the two movable plates 14 are respectively provided with slots 1401 that are adapted to the structure of the fixed blocks 16; the two fixed blocks 16 are respectively inserted into the slots 1401 on the movable plates 14 on the same side, so that the fixed blocks 16 on the arc-shaped electric slider 15 provide support force to the side of the movable plate 14 away from the central column 13, reducing the downward force borne by the connection between the movable plate 14 and the central column 13, thereby improving the service life of the connection between the movable plate 14 and the central column 13; the two fixed blocks 16 are respectively slidably connected to the arc-shaped electric slider 15 on the same side; each of the two arc-shaped electric sliders 15 is equipped with a spring-type damping telescopic rod 17; the telescopic ends of the two spring-type damping telescopic rods 17 are respectively fixed to the fixed blocks 16 on the same side; a pressure sensor 18 is respectively installed on one end of the two spring-type damping telescopic rods 17 that are fixed to the fixed blocks 16.

[0030] When viewers stand on the bottom giant screen 2 for close-up immersive viewing, the curved electric slider 15 pulls the fixed block 16 via the spring-loaded damping telescopic rod 17, causing the side giant screen 3 on the movable plate 14 to rotate and adjust its angle. If a viewer falls and collides with the side giant screen 3 on the movable plate 14 during the rotation towards the viewer, the viewer will push the side giant screen 3, causing the fixed block 16 connected to the movable plate 14 to compress the spring-loaded damping telescopic rod 17. This allows the spring-loaded damping telescopic rod 17 to absorb the impact of the collision on the side giant screen 3, reducing the impact on the side. To prevent damage to the giant screen 3 from collisions, and to reduce the impact injuries to viewers who fall and collide with the side giant screen 3, the pressure sensor 18 will detect an unexpected compression of the spring-dampened telescopic rod 17. This will cause the arc-shaped electric slider 15 to temporarily stop all actions of pulling the side giant screen 3 on the movable plate 14 towards the viewer, thus preventing the side giant screen 3 from crushing the viewer during the flipping process. The arc-shaped electric slider 15 can only resume performing the action of pulling the side giant screen 3 on the movable plate 14 towards the viewer after the laser rangefinder 51 detects that the viewer who has fallen has safely moved away from the side giant screen 3.

[0031] Example 3, based on Example 1 above, as follows: Figures 1-8 As shown, in this embodiment, a plurality of shock-absorbing buffer pads 19 are fixedly connected to the upper side of the base 11; the shock-absorbing buffer pads 19 are clamped between the base 11 and the bottom giant screen 2.

[0032] When viewers stand on the bottom giant screen 2 for close-up immersive viewing, if the content they are watching causes them to feel a strong shock and they exhibit violent physical actions, such as jumping excitedly or stomping their feet, the base 11 provides anti-vibration buffer protection for the bottom giant screen 2 through the upper shock-absorbing buffer pad 19. This allows the shock-absorbing buffer pad 19 to absorb the impact of being stepped on by the bottom giant screen 2 in a timely manner, thereby improving the service life of the bottom giant screen 2.

[0033] Example 4, based on Example 1 above, as follows: Figures 1-7 As shown, the base 11 in this embodiment is designed with a fan-shaped cross-section when viewed from above, and the front side of the base 11 is designed with an arc-shaped structure with a radius length that is the same as the length of the long side structure of the side giant screen 3; a number of warning line spotlights 91 are installed on the arc-shaped structure on the front side of the base 11.

[0034] When viewers stand in front of the base 11 for long-distance naked-eye 3D visual viewing, all the warning line spotlights 91 together illuminate a complete arc-shaped warning cursor line on the ground in front of the base 11. At the same time, the staff indicates that the viewers should stand in front of the arc-shaped warning cursor line for viewing. At this time, the axis of the arc-shaped warning cursor line coincides with the extended intersection line of the two side giant screens 3, and the radius of the arc-shaped warning cursor line is the optimal viewing distance. Therefore, viewers standing in different areas of the arc-shaped warning cursor line can all view the naked-eye 3D visual image presented by the bottom giant screen 2 and the two side giant screens 3 from a good angle.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
