Description

Technical Field

[0001] This utility model relates to the field of screen technology, and more specifically, to a hyperboloid inner dome integrated machine. Background Technology

[0002] In the field of modern display technology, dome displays are widely used in scientific demonstrations, education, virtual reality, and other scenarios due to their immersive visual experience. With technological advancements and growing user demands, hyperboloid dome displays have gradually become a focus of market attention. Their unique curved design not only provides a wider viewing angle but also effectively reduces image distortion and enhances visual effects. However, the overall performance of dome display devices largely depends on the precision and stability of their internal structure, thus placing higher demands on the support structure and installation process.

[0003] Existing dome display equipment typically employs welding to assemble the support frame and spherical display modules to ensure structural strength and maximize production efficiency. However, due to the stringent requirements for the curved transition of the dome's inner surface, the manufacturing precision of the support frame directly impacts the installation effect and image quality of the display screen. When welding is used, the thermal stress during the welding process can easily cause deformation of the support frame, leading to a decrease in structural precision. This compromises the smooth transition of the curved surface within the dome, negatively affecting the display effect, such as uneven image quality and viewing angle deviation.

[0004] Therefore, there is a need to provide a hyperboloid inner dome integrated machine to solve the problem that the above-mentioned dome equipment uses a welding fixing method, which causes deformation of the support frame and cannot guarantee the curved transition of the inner surface of the dome.

[0033] Reference Figures 1 to 7This utility model proposes a hyperboloid inner dome integrated machine, including a display module 1 and a spherical main frame 2, wherein the display module 1 is disposed on the inner spherical surface of the main frame 2;

[0034] The main frame 2 includes a support frame 210 and a support beam assembly 220. The support beam assembly 220 includes several crossbeams 221 and several longitudinal beams 223. The crossbeams 221 are fixedly connected to the opposite sides of the support frame 210, and the longitudinal beams 223 are fixedly connected to the inner top wall and inner bottom wall of the support frame 210. The crossbeams 221 are provided with a first latch 222, and the longitudinal beams 223 are provided with a second latch 224. The first latch 222 and the second latch 224 are engaged so that the crossbeams 221 and the longitudinal beams 223 are fixedly connected perpendicularly to each other.

[0035] In the above embodiment, the main frame 2 is the load-bearing structure of the hyperboloid inner dome integrated machine, and is spherical to adapt to the geometric requirements of the hyperboloid inner dome. The display module 1 is attached to the inner spherical surface of the main frame 2. The main components of the main frame 2 include a support frame 210 and a support beam assembly 220. The support frame 210 constitutes the external frame of the entire frame, providing basic overall support. The support beam assembly 220 is a key internal support component of the main frame 2, consisting of several horizontal beams 221 and several vertical beams 223. The horizontal beams 221 are arranged along the opposite sides of the support frame 210 and fixedly connected to it. The vertical beams 223 are distributed along the height direction, vertically arranged between the inner top wall and inner bottom wall of the support frame 210 and fixedly connected. The staggered arrangement of the horizontal beams 221 and the vertical beams 223 ensures that the structure of the entire frame has both high strength and meets the curvature requirements of the inner dome.

[0036] The crossbeam 221 is equipped with a first latch 222, and the longitudinal beam 223 is equipped with a second latch 224. The first latch 222 and the second latch 224 are fastened and fixed together by a snap-fit ​​mechanism. The fit of the latches ensures the precise vertical positioning of the crossbeam 221 and the longitudinal beam 223, thereby improving the overall accuracy of the support structure. Secondly, the snap-fit ​​method, which is a non-welding fixing method, avoids the problem of frame deformation caused by thermal stress, greatly improving the stability and reliability of the frame and effectively ensuring the curved transition of the inner surface of the dome screen.

[0037] Furthermore, for connections between non-snap-fit ​​structural components, riveting is preferred. This enhances the connection strength and stability, achieving a tight connection without compromising the original material properties. In the hyperboloid inner dome screen integrated machine, the arrangement of riveting points ensures that the entire frame maintains a stable geometric shape and precision under various external forces and loads, thereby guaranteeing that the display module 1 can fit snugly against the inner spherical surface of the main frame 2, achieving a high-quality display effect.

[0038] In summary, the display module 1 is installed on the inner spherical surface of the main frame 2. The main frame 2 forms a unified support structure through a combination of support frames 210 and support beam assemblies 220. The support beam assemblies 220 are fixedly connected to multiple horizontal beams 221 and multiple vertical beams 223 via a snap-fit ​​structure, effectively enhancing the overall strength of the main frame 2 and improving precision control during assembly. This better meets the stringent requirements for the transition of the inner spherical surface. Furthermore, the snap-fit ​​connection structure between the horizontal beams 221 and the vertical beams 223 facilitates the foundation installation of the support structure, significantly reducing the complexity of the assembly process and further ensuring a precise transition of the inner surface of the dome screen, thus improving the installation effect of the display module 1.

[0039] refer to Figure 2 and Figure 3 In one embodiment, a support plate 3 is also included. The longitudinal beam 223 has a snap-fit ​​protrusion on the side facing the display module 1. The snap-fit ​​protrusion penetrates the support plate 3 so that the support plate 3 is fixedly connected to the longitudinal beam 223.

[0040] In the above embodiment, the support plate 3 further enhances the overall structural stability. The snap-fit ​​protrusions on the longitudinal beams 223 facing the display module 1 possess sufficient strength and rigidity to ensure a reliable fixed connection when they penetrate the support plate 3 for clamping. The support plate 3 has pre-drilled holes for engaging the snap-fit ​​protrusions; the snap-fit ​​protrusions align with these pre-drilled holes on the support plate 3, ensuring a tight fit between them. This connection method between the snap-fit ​​protrusions and the pre-drilled holes on the support plate 3 not only simplifies the assembly process but also significantly improves the stability and durability of the structure. Simultaneously, the support plate 3 connects each longitudinal beam 223, providing an additional support point for the longitudinal beams 223, allowing for a more even distribution of pressure when the overall structure is subjected to external forces, further enhancing the strength and stability of the entire dome screen unit.

[0041] refer to Figure 1 and Figure 2 In one example, the display module 1 includes multiple curved screen panels 101, the support plate 3 is provided with a number of fixing holes, and the curved screen panels 101 are provided with mounting pins corresponding to the fixing holes. The fixing holes and mounting pins cooperate to fix the support plate 3 to the curved screen panels 101.

[0042] In the above embodiment, the display module 1 is composed of multiple curved screen panels 101, which are seamlessly spliced ​​together to form the inner surface of the dome, providing viewers with a broad visual experience. A number of fixing holes are evenly distributed on the support plate 3, ensuring that the curved screen panels 101 can be accurately and stably installed on the support plate 3. Each curved screen panel 101 is equipped with mounting pins corresponding to the fixing holes, and the material and size of the mounting pins ensure that they can be firmly fixed in the fixing holes of the support plate 3. When the mounting pins are inserted into the fixing holes, a tight connection is formed between the curved screen panels 101 and the support plate 3, which not only enhances the stability of the structure but also ensures the positional accuracy of the curved screen panels 101 during long-term use, thereby ensuring a precise curved transition of the inner surface of the dome.

[0043] refer to Figure 5 In one embodiment, the longitudinal beam 223 is provided with a relief groove 225, and the relief groove 225 is provided with a mounting plate 4. The mounting plate 4 is fixedly connected to the longitudinal beam 223, and a circuit board 5 is fixedly connected to one end face of the mounting plate 4 facing the display module 1. The circuit board 5 is electrically connected to the display module 1.

[0044] In the above embodiment, a clearance groove 225 is provided on the longitudinal beam 223, and a mounting plate 4 is installed in the clearance groove 225. The mounting plate 4 is fixedly connected to the longitudinal beam 223, and its function is to provide support and fix the position of the circuit board 5. The circuit board 5 is fixedly connected to the end face of the mounting plate 4 facing the display module 1. The circuit board 5 is electrically connected to the display module 1 and is responsible for providing power and signal transmission to the display module 1. At the same time, the configuration of the mounting plate 4 and the clearance groove 225 ensures the reasonable arrangement of the circuit board 5 inside the frame, avoids the messy arrangement of cables, and effectively improves the overall structural compactness and reliability of the equipment. This structure complements the overall structure of the aforementioned support frame 210 and support beam assembly 220, ensuring the stability of the frame and the efficient operation of the display module 1.

[0045] In one embodiment, the clearance groove 225 is provided with a connecting arm 226 extending toward the circuit board 5. The circuit board 5 has a clearance hole for the connecting arm 226 to pass through. A T-shaped connecting plate 6 is connected to one side of the connecting arm 226. A support pad 7 is fixedly connected to one end of the connecting plate 6 near the display module 1. The support pad 7 is fixedly connected to the display module 1.

[0046] In the above embodiment, a connecting arm 226 extending towards the circuit board 5 is provided in the clearance groove 225. The connecting arm 226 is used to further optimize the fixing structure relationship between the display module 1 and the main frame 2. A clearance hole is provided on the circuit board 5, through which the connecting arm 226 passes. A T-shaped connecting plate 6 is connected to one side of the connecting arm 226. This connecting plate 6 provides a larger contact surface for supporting and fixing the support pad 7. The support pad 7 is close to one end of the display module 1 and is fixedly connected to the display module 1, providing additional support and protection for the display module 1. Through the cooperation of the connecting arm 226, the connecting plate 6, and the support pad 7, the installation of the display module 1 is further stabilized, ensuring the accuracy of the inner spherical structure and the long-term performance of the equipment.

[0047] refer to Figure 6 and Figure 7 In one embodiment, it further includes a plurality of L-shaped first connectors 8, the first side of the first connector 8 being fixedly connected to the mounting plate 4, and the second side of the first connector 8 being fixedly connected to the longitudinal beam 223, so that the mounting plate 4 and the longitudinal beam 223 are fixedly connected.

[0048] In the above embodiment, several L-shaped first connectors 8 are used to strengthen the fixing structure between the mounting plate 4 and the longitudinal beam 223. The first side of each first connector 8 is fixedly connected to the mounting plate 4, and the second side is fixedly connected to the longitudinal beam 223. The L-shaped structure provides support on both sides, firmly binding the mounting plate 4 and the longitudinal beam 223 together. The L-shaped design allows the connectors to provide multi-directional support, which not only improves the stability of the connection but also effectively disperses the stress on the mounting plate 4, preventing loosening or deformation due to force in one direction. This optimizes the assembly relationship between the mounting plate 4 and the longitudinal beam 223, ensures the accurate installation position of the circuit board 5, and further enhances the stability and durability of the overall frame structure.

[0049] In one embodiment, it further includes a plurality of L-shaped second connectors 9. The crossbeam 221 is fixedly connected to the opposite sides of the support frame 210 through the second connectors 9. The longitudinal beam 223 is fixedly connected to the inner top wall and inner bottom wall of the support frame 210 through the second connectors 9. The second connectors 9 are fixedly connected at the snap-fit ​​joint between the crossbeam 221 and the longitudinal beam 223.

[0050] In the above embodiment, several L-shaped second connectors 9 are provided to further strengthen the fixed connection structure between the crossbeam 221, the longitudinal beam 223, and the support frame 210. Specifically, the crossbeam 221 is fixedly connected to the opposite sides of the support frame 210 through the second connectors 9, ensuring the stability and horizontal positioning of the crossbeam 221; the longitudinal beam 223 is fixedly connected to the inner top wall and inner bottom wall of the support frame 210 through the second connectors 9, ensuring the vertical positioning and overall support performance of the longitudinal beam 223. In addition, second connectors 9 are fixedly connected at the snap-fit ​​joint between the crossbeam 221 and the longitudinal beam 223 to strengthen the structural strength and stability of the snap-fit ​​joint.

[0051] The L-shaped second connector 9, through its multi-directional support capabilities, disperses the stress on the crossbeam 221 and longitudinal beam 223 at the snap-fit ​​joint, avoiding structural loosening or deformation that may result from localized stress concentration. This design further optimizes the overall rigidity between the support frame 210, crossbeam 221, and longitudinal beam 223, enhancing the overall stability and precision of the main frame 2, and ensuring that the display module 1 can be precisely installed in the inner spherical structure.

[0053] In the above embodiments, the curved cover plate 10 effectively enhances the aesthetics and protection of the overall structure. The design of the curved cover plate 10 conforms to the end shape of the support beam assembly 220, which not only has a smooth and harmonious appearance, but also effectively prevents external factors such as dust and moisture from corroding the support beam assembly 220 and its internal structure.

[0054] refer to Figure 8 In one embodiment, a support frame 11 is fixedly connected to the bottom end of the main frame 2, a storage platform 12 is mounted on the inner side of the support frame 11, and a number of casters 13 are fixedly connected to the bottom end of the support frame 11.

[0055] In the above embodiment, a support frame 11 is fixedly connected to the bottom of the main frame 2 to further improve the stability and load-bearing capacity of the entire machine. The support frame 11 not only supports the main frame 2, but also has a storage platform 12 on its inner side, providing additional storage and functional expansion space for the equipment. For example, the storage platform 12 can be used to place power supply equipment, signal processing devices, or other auxiliary devices, making the overall structure more compact and functionally integrated.

[0056] In addition, several casters 13 are fixedly connected to the bottom of the support frame 11, giving the equipment efficient mobility. The casters 13 allow the hyperboloid dome screen to be easily moved during use or maintenance, increasing the flexibility of equipment deployment. This mobility is particularly important in complex usage scenarios, such as exhibition or educational venues. Through the combined design of the support frame 11, the storage platform 12, and the casters 13, not only is the practicality of the main frame 2 enhanced, but the ease of operation and functional expansion capabilities of the equipment are also optimized, further improving the overall performance of the equipment.
