Description

Technical Field

[0001] This utility model relates to the field of naked-eye display technology, specifically a capsule-shaped hollow panoramic digital RVR naked-eye dynamic immersive display device. Background Technology

[0002] Against the backdrop of the rapid development of multimedia display and virtual reality (VR) technology, users' demands for visual experience are increasing, especially in fields such as exhibitions, immersive cinemas, virtual reality experience centers, and commercial advertising. There is a growing demand for panoramic display devices that can provide 360° viewing angles, are viewable without the naked eye, and offer dynamic interaction.

[0003] Limited field of view and simple shape structure Traditional glasses-free VR devices mostly use a single geometric structure: Cylindrical devices (such as CN210200247U) only achieve a horizontal 360° field of view, with a vertical field of view of ≤180°. There are obvious blind spots at the top and bottom. In scenarios that require top / bottom view interaction (such as architectural walkthroughs), the information loss rate is ≥30%. Although hemispherical devices (such as CN112326189A) cover the upper hemisphere field of view, the bottom field of view is completely missing, which cannot meet the needs of full-space immersion.

[0004] In the existing technology, there is a lack of composite display configurations with capsule-shaped bodies (combination of a cylinder and two hemispheres at both ends), especially in the image fusion of the transition area between the hemispheres and the cylinder, which results in a splicing distortion rate of >15%.

[0005] Mechanical design defects of the support frame Insufficient structural stability: Traditional support frames are mostly single-layer ring structures, such as the rectangular steel tube frame of CN209844312U, which cannot simultaneously support cylindrical arc screens and hemispherical circular screens. Lack of optical design and insufficient immersive experience Existing equipment casings are mostly single cylindrical or spherical surfaces, failing to form a capsule-shaped composite reflective cavity, resulting in: The light refraction angle deviation at the top of the cylinder is ≥20°, and the brightness attenuation in the central viewing area reaches 45%. Light cannot be effectively reflected at the bottom of the hemisphere, creating a visually dark area and resulting in a poor immersive experience; The compatibility shortcomings of screen fixing technology Traditional fasteners cannot be adapted to both cylindrical curved surfaces and hemispherical spherical surfaces. For example, the snap-fit ​​structure of CN210225165U is only suitable for flat screens. For hemispherical circular screens, additional custom brackets are required, which reduces installation efficiency by 40%. Summary of the Invention

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a capsule-shaped hollow panoramic digital RVR naked-eye dynamic immersive display device.

[0007] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: The capsule-shaped hollow panoramic digital RVR naked-eye dynamic immersive display device of the present invention includes a capsule-shaped hollow shell, an LED display module, and a capsule-shaped frame; The hollow outer shell of the capsule is fitted onto the outside of the capsule frame. The hollow outer shell of the capsule is cylindrical. The capsule frame includes a cylindrical frame and a hemispherical frame, with the hemispherical frame located at both ends of the cylindrical frame. The LED display modules are arranged in a ring along the outer wall of the capsule frame; The cylindrical frame and the hemispherical frame each include several layers of annular galvanized steel pipes and fasteners. The LED display module is mounted on the cylindrical frame and the hemispherical frame through the fasteners.

[0008] Preferably, the cylindrical frame consists of several layers of annular galvanized steel pipes of the same diameter, and the hemispherical frame consists of several layers of annular galvanized steel pipes arranged progressively from the maximum diameter of the hemispherical frame to the minimum diameter of the hemispherical frame.

[0009] More preferably, the cylindrical frame and the annular galvanized steel pipes of the hemispherical frame are welded together by a skeleton.

[0010] Preferably, the LED display module includes several curved screens and circular screens. The curved screens are mounted on the outer wall of several layers of annular galvanized steel pipes by fasteners, and the circular screens are mounted on the top of the smallest diameter annular galvanized steel pipe of the hemispherical frame.

[0011] Preferably, the fastener has an L-shaped structure and is located on the side of the curved screen.

[0012] More preferably, each layer of the capsule frame has several clamping grooves surrounding its outer wall on the annular galvanized steel pipe, and the top of the annular galvanized steel pipe with the smallest diameter of the hemispherical frame has a clamping groove, and the fixing member is adapted to the clamping groove.

[0013] Preferably, the fastener has an elastic locking rod on its side, a locking slot is provided on the inner wall of the clamping groove, and a limiting protrusion is provided on the elastic locking rod, the limiting protrusion being adapted to the locking slot.

[0014] Preferably, the bottom of the fixing member has a built-in magnet, which adsorbs the inner wall of the clamping groove.

[0015] Compared with the prior art, this utility model provides a capsule-shaped hollow panoramic digital RVR naked-eye dynamic immersive display device, which has the following beneficial effects: This technical solution achieves a high-quality naked-eye panoramic dynamic visual experience through scientific spatial layout and modular component design. The device consists of three core parts: a hollow capsule shell, an LED display module, and a capsule frame, and has significant advantages such as strong image continuity, convenient installation, and structural stability.

[0016] The capsule's hollow outer shell is cylindrical with hemispherical structures at both ends, giving it an overall "capsule" shape. It is made of translucent material, which effectively protects the internal components without affecting the transparency of the image. The support frame consists of a cylindrical frame and a hemispherical frame, which are arranged in corresponding areas. The cylindrical frame is made of annular galvanized steel pipes of the same diameter, while the hemispherical frame is set with the diameter gradually decreasing from the largest to the smallest. The overall structural strength is enhanced by welding the skeleton.

[0017] The LED display module is composed of multiple curved and circular screens. The curved screens are fitted onto layers of annular galvanized steel pipes, while the circular screens are mounted on top of a hemispherical frame, achieving omnidirectional visual coverage and eliminating blind spots in the center. The fasteners are L-shaped and located on the sides of the screens, featuring elastic levers and limiting protrusions that fit into clamping slots and latches to prevent loosening and detachment. Additionally, built-in magnets at the bottom of the fasteners enhance adhesion, ensuring a stable and reliable installation. This allows for quick assembly and disassembly, improving construction efficiency and ease of maintenance.

[0018] In summary, this technical solution, through reasonable structural design and multiple fixing mechanisms, solves the problems of limited viewing angle, obvious splicing gaps, and complex installation of traditional display devices. It has the advantages of complete picture, stable structure, efficient installation, and convenient maintenance. It is suitable for various immersive application scenarios such as virtual reality display, science and technology museums, commercial advertising, and game experience, and has good industrial promotion value.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 The present invention relates to a capsule-shaped hollow panoramic digital RVR naked-eye dynamic immersive display device, comprising a capsule hollow shell 4, an LED display module 1, and a capsule frame 2; The hollow outer shell 4 of the capsule body is fitted on the outside of the capsule body frame 2. The hollow outer shell 4 of the capsule body is a cylindrical structure. The capsule body frame 2 includes a cylindrical frame 6 and a hemispherical frame 12. The hemispherical frame 12 is located at both ends of the cylindrical frame 6. The LED display module 1 is arranged in a ring along the outer wall of the capsule frame 2; The cylindrical frame 6 and the hemispherical frame 12 each include several layers of annular galvanized steel pipes 5 and fasteners 3. The LED display module 1 is installed on the cylindrical frame 6 and the hemispherical frame 12 through the fasteners 3.

[0022] This technical solution achieves a naked-eye immersive display effect with full visual coverage through structural innovation and modular design. The device is suitable for various demanding application scenarios such as virtual reality experience centers, science and technology exhibition halls, commercial advertising, education and training, and gaming experiences.

[0023] Capsule-based composite optical reflection mechanism The hollow capsule shell 4 (made of polycarbonate with a light transmittance of ≥92%) is fitted onto the outside of the capsule frame 2. The frame consists of a cylindrical frame 6 and hemispherical frames 12 at both ends, forming a closed optical cavity. The LED display module 1 is arranged in a ring along the outer wall of the frame, achieving 720-degree panoramic field of view coverage. Light reflection path: The cylindrical frame 6 and the curved screen 8 enable horizontal 360° light projection; The circular screen of the hemispherical frame 12 reflects light upwards / downwards, supplementing the vertical 360° field of view. After the light is uniformly reflected by the inner wall of the outer shell, an immersive field of view without blind spots is formed in the central area. Field fusion principle: The curvature difference between the cylinder and the hemisphere is compensated by a geometric correction algorithm, and the measured image distortion rate is ≤0.8%.

[0024] LED module collaborative display principle Screen layout strategy: The arc-shaped screen 8 (with the same radius of curvature as the cylindrical frame 6) is arranged in a ring along the cylindrical frame 6, and the gap between adjacent screens is ≤0.4mm; The circular screen body is adapted to the smallest diameter end of the hemispherical frame 12 and seamlessly connected with the curved screen body 8 through edge blending technology (overlapping area 20px), with a resolution ≥8K (7680×4320).

[0025] Working principle of the preferred technical solution Capsule frame 2-layer mechanical structure Cylindrical frame 6: The same diameter annular galvanized steel pipes 5 are arranged at equal intervals along the axial direction and welded into a rigid column by radial skeleton 13. The load-bearing capacity is ≥80kg / m², and the flatness deviation of the arc screen 8 during installation is ≤0.5mm. Hemispherical frame 12: The annular galvanized steel pipe 5 gradually decreases in diameter from the maximum to the minimum. Each layer of steel pipe is welded together by the skeleton 13 to form a hemispherical support structure with a load-bearing capacity of ≥60kg / m², which is compatible with the spherical curvature of the arc-shaped screen 8 and the circular screen. Frame 13 welding process: CO2 shielded welding (welding current 180A±10A) is adopted, and the weld strength is ≥350MPa to ensure the overall rigidity of the frame.

[0026] Magnetic-Snap Composite Fixing System L-shaped fastener 3 structure: Made of aluminum alloy, the right-angled edges are respectively attached to the screen frame and the frame groove 7, and the neodymium iron boron magnet 11 at the bottom is attracted to the inner wall of the groove 7 to generate a pre-tightening force of ≥10N; The side elastic locking rod 9 is inserted into the clamping groove 7, and the limiting protrusion 10 is locked at the edge of the clamping groove, providing a locking force of ≥15N. Under vibration environment, the screen displacement is ≤0.15mm. Clamping groove 7 - Precision fit of the bayonet: The clamping grooves 7 are distributed in a ring along the outer wall of the frame, and the gap error between the clamps is ≤0.2mm, so that the splicing gap after the screen is installed is ≤0.25mm.

[0027] The limiting protrusion 10 and the edge of the bayonet can be designed as an arc-shaped structure. When the screen is removed and pulled outward, the elastic lever 9 will also be squeezed and deformed by the outward pulling force, so that the limiting protrusion 10 will disengage from the bayonet.

[0028] Key steps: Three-dimensional laser positioning (error ≤ 0.5mm) is used during the welding of the hemispherical frame 12 to ensure that the coaxiality of each layer of annular tube is ≤ 0.3mm; The screen is installed in the order of "cylindrical first, then hemispherical". After quick positioning by the magnetic piece 11, press the fixing piece 3 to make the elastic lever 9 snap into the slot. The installation time for a single screen is ≤2.5 minutes.

[0029] Detailed Workflow Summary Step S1: Installation of the outer casing and support frame The hollow capsule shell 4 was transported to the site; Install the cylindrical frame 6 and the hemispherical frame 12 in sequence to form the capsule frame 2; The galvanized steel pipes in each layer are connected by welding or fasteners to ensure the stability of the overall structure.

[0030] Step S2: Installation of LED display module 1 Multiple curved LED screens are sequentially embedded into the grooves 7 of each layer of galvanized steel pipes; The circular LED screen is installed on the top of the hemispherical frame 12 with the smallest diameter. L-shaped fastener 3 is used for locking, elastic lever 9 is inserted into the slot, and limiting protrusion 10 prevents displacement; The bottom magnet 11 of the fastener 3 enhances the adsorption force and ensures that the screen is installed firmly.

[0031] Step S3: System debugging and content playback Complete the line connection and power supply tests; Adjust the display parameters of each screen to ensure that the image blends seamlessly without black borders or misalignment; The content playback system is activated to achieve a naked-eye dynamic immersive visual display.

[0032] Step S4: Use and Maintenance The hollow outer shell 4 of the capsule body is fitted onto the outside of the capsule body frame 2 to protect the LED display module 1; Users can freely view the panoramic view in the central area of ​​the device without wearing glasses; The equipment supports modular replacement; individual screens or fasteners can be disassembled and repaired separately. The displayed content and playback mode can be flexibly adjusted according to the application scenario.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
