Description

Technical Field

[0001] The present invention relates to the technical field of LED display screens, and in particular to an anti-trampling assembly structure of an immersive LED floor screen and a maintenance method thereof. Background Art

[0002] As LED display technology matures, its development is becoming more scenario-specific and practical. Customer demands are increasingly diverse based on the specific usage scenarios, with the demand for immersive experiences being particularly pressing. Immersive screens often require floor screens, allowing viewers to stand on them and, combined with the display on the side screens, experience an immersive visual experience.

[0003] Traditional floor screens are assembled in the same way as conventional screens, and are both assembled into a whole through module units in sequence. However, they face three major problems: first, the screen can be easily damaged by being stepped on, and the lamp beads need to be effectively protected; second, there is a problem of splicing seams, which will be aggravated by prolonged stepping on them, thus damaging the integrity of the picture. As the pitch between the floor screen dots decreases, the splicing problem becomes more prominent; third, installation and maintenance are difficult. The front maintenance magnetic suction method can easily cause the module to move and damage the lamp beads, while the rear maintenance fixed installation method makes it difficult to disassemble and install the module, increasing the difficulty of later maintenance.

[0004] To address the above challenges, R&D personnel proposed the following solutions for different periods and scenarios:

[0005] (1) Early solution: A viewing platform is set up above the assembled floor screen, where the audience can experience an immersive scene. Although this solution can effectively protect the screen and facilitate assembly and maintenance, the viewing platform area is limited, and some point modules need to be destroyed when welding the platform structure. The platform and columns will block the picture, affecting the experience.

[0006] (2) Mid-term solution: A large area of ​​tempered glass is laid on the surface of the assembled screen to evenly distribute the force when stepped on, thus protecting the lamp beads. This solution improves the problem of screen obstruction, but the glass needs to be moved during maintenance, which is inconvenient. In addition, the joints between the tempered glass cannot be eliminated. At the same time, the glass is easily shattered when subjected to sharp pressure, posing a safety hazard.

[0007] (3) Current solution: The module is fixed to a sheet metal or die-cast aluminum enclosure, with a light-transmitting, pressure-resistant PVC mask added to the surface. An adjustable base is customized to adjust the enclosure flatness, and base locating pins are used to minimize the gap between the enclosures. To balance maintenance convenience and gap control, a front maintenance solution is being developed that uses magnetic suction to secure the module to the enclosure.

[0008] However, the above solution still has defects:

[0009] (1) The viewing platform solution is limited by the structural design, and the screen occlusion problem is significant.

[0010] (2) The tempered glass solution is difficult to maintain, has residual seams, and poses safety risks.

[0011] (3) Although the current cabinet solution (divided into two types: die-cast aluminum cabinet and sheet metal cabinet) has solved most of the problems, the post-maintenance solution is affected by the manufacturing accuracy and redundant space, and it is difficult to completely control the flatness and gaps. Long-term stepping on it can easily cause the cabinet to move. If a connecting lock is used to lock the cabinet, due to the size of the cabinet (such as 500×500mm) and the ground laying method, the construction workers cannot operate on the bottom surface. After large-scale assembly, maintenance requires the removal of entire rows and columns, which is extremely difficult. The front maintenance solution faces the problem of waterproofing in outdoor environments.

[0012] Therefore, the current research and development direction focuses on designing an optimization solution that can further adjust the flatness and gaps based on the post-maintenance of the cabinet assembly without affecting the subsequent maintenance. Summary of the Invention

[0040] In order to make the technical solution, the technical problems solved and the technical effects of the present invention more clear, the technical solution of the present invention is clearly and completely described below in conjunction with specific embodiments.

[0041] Example 1:

[0042] Reference Attachment Figure 1 、 2 3. This embodiment proposes an anti-trampling assembly structure for an immersive LED floor screen, which includes a box unit 1 with a built-in module unit, a support rod 2 located below the box unit 1, and an adjustable bottom support 3.

[0043] The side panels 5 of the box unit 1 extend downward beyond the lower surface of the bottom panel 9;

[0044] A funnel-shaped slot 4 is provided on the upper surface of the support rod 2. The funnel-shaped slot 4 is in an inverted figure eight shape that is wide at the top and narrow at the bottom.

[0045] When at least two box units 1 are assembled, an adjustable base support 3 is provided below the non-contact position of the side panels 5 of adjacent box units 1. The adjustable base support 3 lifts the box unit 1 upward, and a support rod 2 is provided below the contact position of the side panels 5 of adjacent box units 1. The adjustable base support 3 is fixed to the bottom surface of the support rod 2. The extended parts of the side panels 5 of adjacent box units 1 are simultaneously inserted downward into the lower narrow opening of the funnel-shaped slot 4 to eliminate the joints between the adjacent box units 1 through the clamping force of the funnel-shaped slot 4.

[0046] In this embodiment, to facilitate the assembly of multiple cabinet units 1, the width of the lower narrow opening of the funnel-shaped slot 4 is D, the thickness of the side panels of the cabinet unit 1 is d, and 0.93D ≤ 2d ≤ D. For example, if the thickness d of the side panels 5 of the cabinet unit 1 is 3.3 mm, then the width D of the lower narrow opening of the funnel-shaped slot 4 is 7 mm. The lower narrow opening of the support rod 2 allows the side panels 5 of two cabinet units 1 to be connected, thereby tightening the two adjacent cabinet units 1 and eliminating the gap between them.

[0047] Reference Attachment Figure 1 、 2 In the figure, a, b, c, and d are the specific numbers of the box units 1, and ①②③④⑤⑥⑦⑧⑨ are the numbers of the adjustable base supports 3. Taking the assembly of four box units (a, b, c, d) as an example, adjustable base supports ②④⑤⑥⑧ are respectively installed at both ends of the support rod 2 that connect the adjacent box units (a and b, a and c, b and d, c and d), and adjustable base supports ①③⑦⑨ are installed under the four corners exposed to the outside after the four adjacent box units (a, b, c, d) are assembled. With the help of the funnel-shaped slot 4 of the support rod 2, the connection of two adjacent box units (a and b, a and c, b and d, c and d) can be achieved, and by adjusting the adjustable base support 3, the joint between two adjacent box units (a and b, a and c, b and d, c and d) can be minimized as much as possible.

[0048] Based on the structure of this embodiment, it can be further supplemented that:

[0049] 1. The adjustable base 3 includes a non-slip base 7, a cup screw 6 threadedly connected to the non-slip base 7, and a support plate 8 rotatably connected to the top of the cup screw 6. The support plate 8 lifts the box unit 1 upward. Alternatively, the adjustable base 3 includes a non-slip base 7, a cup screw 6 threadedly connected to the non-slip base 7, a threaded sleeve that cooperates with the cup screw 6 and is connected to the threaded sleeve, and a support plate 8 fixed to the top of the threaded sleeve. The support plate 8 lifts the box unit 1 upward.

[0050] 2. At least three threaded holes are provided on the bottom surface of the funnel-shaped slot 4 of the support rod 2 , and bolts pass through the threaded holes to push up the side panels of the box unit in the funnel-shaped slot 4 .

[0051] 3. The cabinet unit 1 adopts a die-cast aluminum cabinet or a sheet metal cabinet.

[0052] It should be added that 1, 2, and 3 are optimized designs of the assembly structure described in this embodiment, which are intended to better realize the assembly of multiple box units 1, reduce the joints, and improve the surface flatness after the multiple box units 1 are connected into a whole.

[0053] Example 2:

[0054] This embodiment provides a maintenance method for the anti-trampling assembly structure of an immersive LED floor screen, which is based on the anti-trampling assembly structure described in Example 1 and includes the following maintenance process:

[0055] S1. Use the front maintenance method to remove the module unit from the box frame of the box unit 1 through the magnetic suction component for maintenance;

[0056] S2. When assembling multiple box units 1, first, support rods 2 are set below the contact positions of the side panels 5 of adjacent box units 1, so that the extended parts of the side panels 5 of adjacent box units 1 can be simultaneously inserted downward into the lower narrow openings of the funnel-shaped slots 4. The clamping force of the funnel-shaped slots 4 eliminates the joints between the adjacent box units 1. Then, adjustable bottom supports 3 are fixed to the bottom surfaces of the support rods 2, and adjustable bottom supports 3 are also set below the non-contact positions of the side panels 5 of adjacent box units 1. The adjustable bottom supports 3 lift the box units 1 upward. Finally, the heights of the adjustable bottom supports 3 are adjusted.

[0057] S3. Check the joints between adjacent cabinet units 1 and adjust the adjustable bottom bracket 3 under the support rod 2 until the joint width meets the requirements;

[0058] S4. Use a level to calibrate the flatness of the top surface of the cabinet unit 1, and check to make sure that the joints between adjacent cabinet units 1 meet the requirements.

[0059] It should be noted that the width of the lower narrow opening of the funnel-shaped slot 4 is D, the thickness of the side panel 5 of the box unit 1 is d, and 0.93D≤2d≤D. The joint can be required to be less than D / 10, and the joint width is less than 0.7 mm.

[0060] It should be added that in order to better reduce the gap between adjacent box units 1, at least three threaded holes are opened on the bottom surface of the funnel-shaped slot 4 of the support rod 2. Bolts pass through the threaded holes to push up the side panels 5 of the box unit 1 in the funnel-shaped slot 4, thereby achieving fine-tuning of the height of the box unit 1 and reducing the gap after assembly.

[0061] In summary, the anti-trampling assembly structure and maintenance method of an immersive LED floor screen of the present invention can be used to reduce the gap between adjacent box units by adjusting the assembly structure, avoid the collapse phenomenon caused by long-term trampling, improve the surface flatness of multiple box units after assembly, improve service life and user experience, and facilitate the adjustment of gaps and flatness in the later stage.

These examples are only used to help understand the core technical content of the present invention. Based on the above specific embodiments of the present invention, any improvements and modifications made by those skilled in the art without departing from the principles of the present invention should fall within the scope of patent protection of the present invention.
