Description

Technical Field

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

[0002] With the development of virtual reality (VR) technology, immersive display devices are increasingly being used in education, training, exhibitions, and other scenarios. However, current mainstream VR devices all rely on wearable equipment such as headsets and glasses, leading to the following technical bottlenecks for users:

[0003] Limitations of the Wearable Device Experience

[0004] Physiological discomfort: Headsets generally weigh ≥300g, and prolonged wear can easily cause cervical spine compression and visual fatigue. For example, the Oculus Quest 2 headset weighs 375g, and the incidence of dizziness among users who use it continuously for more than 1 hour is ≥40%.

[0005] Realism is disrupted: Wearing the equipment isolates the user from the real environment, making it impossible to achieve a seamless virtual-real experience. This is especially true in scenarios that require physical interaction (such as offline large-space VR games), where the risk of tangled cables is high.

[0006] While existing glasses-free VR technology attempts to solve the wearing problem, it has significant drawbacks:

[0007] The naked-eye 3D display device disclosed in CN210200247U adopts a single cylindrical structure with a field of view of only 270°, which cannot cover the vertical viewing angle.

[0008] Due to limitations in curved screen splicing technology, the hemispherical display device described in CN112326189A has a splicing gap of ≥1mm at the top and bottom edges, resulting in an image distortion rate of >5%.

[0009] Structural defects of display devices

[0010] Insufficient spatial adaptability: Traditional spherical and cylindrical display devices struggle to balance field of view coverage with installation space requirements. For example, a cylindrical device with a diameter of 3 meters has a horizontal field of view of 360°, but a vertical field of view of only 180°, making it impossible to achieve a 720-degree panoramic view.

[0011] Optical design deficiencies: Existing physical structures do not optimize light reflection paths for naked-eye displays. For example, the naked-eye VR device CN211508548U does not consider the light refraction angle of curved screens, resulting in a 30% decrease in brightness in the central viewing area.

[0012] Lagging behind in support and installation technologies

[0013] Inefficient fixing methods: Traditional support frames mostly use bolted connections. For example, the display screen fixing structure of CN209844312U requires 6 bolts to install a single screen, which takes ≥15 minutes and results in low maintenance efficiency. Utility Model Content

[0014] (a) Technical problems to be solved

[0015] To address the shortcomings of existing technologies, this invention provides a dual-faceted spherical cylindrical panoramic digital RVR naked-eye dynamic immersive display device.

[0016] (II) Technical Solution

[0017] To achieve the above objectives, this utility model provides the following technical solution: The dual-faceted spherical cylindrical panoramic digital RVR naked-eye dynamic immersive display device of this utility model includes a dual-faceted spherical cylindrical shell, an LED display module, and a support frame.

The LED display module is fixedly installed on the support frame by fasteners.

[0018] Preferably, the double-faceted spherical cylinder shell is a hollow spherical cylinder structure, and the double-faceted spherical cylinder shell includes an upper facet and a lower facet, with the rectangular galvanized steel pipe arranged on the lower facet.

[0019] More preferably, the LED display module includes several curved screens and rectangular screens. The curved screens are mounted on curved galvanized steel pipes by fasteners, and the rectangular screens are mounted on rectangular galvanized steel pipes by fasteners.

[0020] Preferably, the fastener has an L-shaped structure and is located at the corner of the display screen.

[0021] Preferably, the inner sides of the arc-shaped galvanized steel pipe and the rectangular galvanized steel pipe are symmetrically provided with two clamping grooves, the fixing member is adapted to the clamping grooves, the inner side of the fixing member is provided with an elastic locking rod, the two sides of the arc-shaped galvanized steel pipe and the rectangular galvanized steel pipe are provided with locking slots, and the locking slots are adapted to the clamping grooves. The elastic locking rod is provided with a limiting protrusion, and the limiting protrusion is adapted to the locking slots.

[0022] More preferably, the bottom of the fixing member has a built-in magnet, which attracts the arc-shaped galvanized steel pipe and the rectangular galvanized steel pipe.

[0023] Preferably, the arc-shaped galvanized steel pipe and the rectangular galvanized steel pipe are fixedly installed on the shell of the double-cut spherical cylinder by bolts.

[0024] (III) Beneficial Effects

[0025] Compared with the prior art, this utility model provides a dual-faceted spherical cylindrical panoramic digital RVR naked-eye dynamic immersive display device, which has the following beneficial effects:

[0026] By integrating components such as a double-faceted spherical cylinder shell, LED display modules, and a supporting frame, a comprehensive visual display effect is achieved. This equipment demonstrates significant advantages in structural design, ease of installation, display effect, and stability.

[0027] First, the double-faceted spherical shell adopts a hollow spherical structure, including an upper and lower facet, providing flexibility in space utilization. This design not only reduces the overall weight, facilitating transportation and installation, but also provides diverse layout options for different application scenarios. Rectangular galvanized steel pipes are arranged on the lower facet, enhancing the stability of the bottom support and ensuring the stability of the entire equipment's center of gravity, preventing tilting or swaying.

[0028] Secondly, the support frame comprises curved and rectangular galvanized steel pipes, which are respectively arranged around the inner wall and bottom of the double-faceted spherical cylinder shell, providing uniform and strong support. These steel pipes are bolted to the double-faceted spherical cylinder shell, ensuring the structure's robustness and durability. In particular, the design of the curved galvanized steel pipes perfectly conforms to the curvature of the curved screen, ensuring the continuity and consistency of the image, thereby achieving a seamless panoramic display effect.

[0029] Furthermore, the LED display module consists of several curved and rectangular screens, which are mounted on a support frame using L-shaped fasteners. The L-shaped fasteners simplify the installation process, allowing the screens to be quickly and securely fixed in their designated positions. The inner side of the fastener features a flexible locking rod with adjustable limiting protrusions, which mate with the grooves and slots on the galvanized steel pipes, ensuring precise positioning and stability during installation. In addition, a built-in magnet at the bottom of the fastener further enhances the magnetic attraction, preventing the screens from loosening and improving overall stability.

[0030] Of particular note is the device's ability to achieve glasses-free dynamic immersive display, allowing users to enjoy a panoramic visual experience without wearing any auxiliary devices. The seamless stitching of multiple curved and rectangular screens creates a panoramic view, delivering an unprecedented level of immersion. Whether used for exhibitions, virtual reality experiences, gaming, or large-scale events, this device provides outstanding visual effects, attracting audience attention and enhancing the interactive experience.

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.

[0037] Please see Figure 1-4 The present invention relates to a double-faceted spherical cylindrical panoramic digital RVR naked-eye dynamic immersive display device, comprising a double-faceted spherical cylindrical shell 4, an LED display module 1, and a support frame 2. The support frame 2 comprises an arc-shaped galvanized steel pipe 5 and a rectangular galvanized steel pipe 6. The arc-shaped galvanized steel pipe 5 is arranged around the inner wall of the double-faceted spherical cylindrical shell 4, and the rectangular galvanized steel pipe 6 is arranged at the bottom of the double-faceted spherical cylindrical shell 4. The LED display module 1 is fixedly installed on the support frame 2 by a fastener 3.

[0038] This equipment integrates components such as a double-faced spherical cylinder shell 4, an LED display module 1, and a support frame 2 to achieve a comprehensive visual display effect. The equipment employs an innovative structural design and advanced fixing technology to ensure high stability and convenient installation, making it suitable for various exhibitions, virtual reality experiences, gaming experiences, and other scenarios.

[0039] Double-faceted spherical cylinder shell 4

[0040] It adopts a hollow spherical cylinder structure, including an upper and lower slab, to provide the basic framework for the entire equipment;

[0041] The outer casing is made of a sturdy yet lightweight material, making it easy to transport and install;

[0042] The inner wall is surrounded by arc-shaped galvanized steel pipes 5, and the bottom is provided with rectangular galvanized steel pipes 6, which are used to support and fix the LED display module 1, so that a 720-degree surround field of view is formed inside.

[0043] Collaborative display principle of LED display module 1

[0044] Combination of curved and rectangular screen bodies:

[0045] The curved screen 8 is arranged in a ring along the transition area between the hemisphere and the cylinder on the inner wall of the outer shell, with the radius of curvature consistent with the inner wall of the outer shell (error ≤ 1mm), covering a horizontal 360° field of view;

[0046] The rectangular screen is arranged on the rectangular galvanized steel pipe 6 with the lower cut surface, which supplements the vertical field of view and forms a 180° vertical coverage, forming a 720° panoramic display surface.

[0047] Signal processing flow: The built-in image processing module resolves the panoramic source into a projection signal that is adapted to the dual-face space, and transmits it to each screen through the HDMI 2.1 interface. Adjacent screens eliminate splicing gaps through edge blending technology (10px overlapping area) to achieve seamless image connection.

[0048] Mechanical support principle of support frame 2

[0049] Arc-shaped galvanized steel pipe 5: The galvanized steel pipe is cold-bent into shape according to the arc of the inner wall of the outer shell, and is fixed around the connection between the hemisphere and the cylinder. It is fixed to the outer shell by bolts and supports the weight of the arc-shaped screen 8.

[0050] 6. Rectangular galvanized steel pipes: Rectangular steel pipes are arranged on the lower cut surface to form a grid-like support structure, which is supported by L-shaped fasteners 3.

[0051] Working principle of the preferred technical solution

[0052] Quick installation mechanism of L-shaped fastener 3 and clamping groove 7

[0053] Structural fit:

[0054] The right-angled sides of the L-shaped fastener 3 correspond to the screen frame and the clamping groove 7 respectively;

[0055] The symmetrical clamping groove 7 on the inner side of the steel pipe slides in conjunction with the right-angled edge of the fixing part 3.

[0056] Elastic lever 9 locking: The elastic lever 9 on the inner side of the fixing part 3 is inserted into the clamping groove 7, and the limiting protrusion 10 is stuck on the edge of the clamping opening to prevent the screen from falling off.

[0057] 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.

[0058] Dual fixing principle of magnet and bolt

[0059] Magnetic pre-fixing: The neodymium iron boron magnet at the bottom of the fixing part 3 is attracted into the clamping groove 7 to assist in the positioning of the screen and prevent shaking during installation.

[0060] Image fusion algorithm

[0061] Fusion Algorithm: The image processing module processes overlapping areas using edge feathering technology (feathering width 5px), and generates a correction matrix by combining dual-face geometric parameters (face angle, screen position) to eliminate field-of-view stitching distortion and ensure that the panoramic image distortion rate is ≤1%.
