Description

Technical Field

[0001] The utility model belongs to the technical field of floor screen boxes and relates to a front-maintained LED floor screen box structure. Background Art

[0002] LED floor screen is a display screen that is laid flat on the ground and can be walked and stepped on in a controlled manner. It can display different lighting effects and graphics and text as needed. It is mostly used in performance venues such as stages, dance floors, and bars. It adds stage effects to performances and scenes, has good visual effects, and is deeply loved by people.

[0003] Traditional LED floor screen cabinets often feature rear- or side-accessible design. This requires moving or disassembling the entire display or parts of it for maintenance. This is not only complex and time-consuming, but also increases maintenance costs and difficulty. Traditional maintenance methods are particularly inconvenient in applications where space is limited or rapid response is required.

[0004] For example, the patent publication number CN220065086U, which describes a magnetically mounted LED interactive floor tile display module, mentions using magnets to attach the module to a cabinet. However, there's no mention of magnet protection, so the magnets will experience some pressure. Furthermore, a separate positioning mechanism is used to protect the module.

[0005] In summary, a front-maintained LED floor screen box structure is now provided. Utility Model Content

DETAILED DESCRIPTION

[0024] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] This utility model provides a front-accessible LED floor screen cabinet structure. It utilizes a stable frame structure and suitable materials to enhance the overall strength and rigidity of the structure. Furthermore, through reasonable mechanical analysis, the design of appropriate support points and connection methods ensures stability in various environments. The specific implementation is described with reference to the accompanying drawings.

[0026] This embodiment includes a main frame 1, with a power supply box 3 mounted on it. The two boxes are welded together. Several connection holes 6 are provided on the side of the main frame for connecting different boxes, which are connected using bolts. During assembly, the boxes are fixed to the sides to improve their firmness. The control board and power supply are placed inside the power supply box. The different boxes can be connected in two ways: using bolts through the connection holes on the side of the main frame, and by aligning the positioning pins 9 of the anchor brackets 4 with the holes at the bottom of the main frame 1 to connect and secure adjacent boxes.

[0027] The LED module positioning plate 2 is installed on the main frame 1 through the mounting hole 7 by means of a countersunk screw; the opening position of the mounting hole 7 is arranged according to the magnet position of the LED module 5, and can adapt to modules of various sizes, not just the one described; the thickness of the LED module positioning plate 2 is the same as the thickness of the magnet. When the LED module 5 is magnetically attracted to the main frame 1, the bottom of the bottom shell of the LED module 5 and the LED module positioning plate 2 contact each other, so that the magnet is not subjected to force, and the force point is placed at the bottom of the bottom shell of the LED module 5, which can improve stability. The magnet sinks into the magnet positioning hole 8 of the module positioning plate 2, which plays a positioning role and avoids the use of other positioning pins for positioning; the top of the magnet contacts the bottom of the bottom shell of the LED module 5, passes through the LED module positioning plate 2, and the lower part of the magnet contacts the main frame 1.

[0028] The floor screen boxes are connected to each other through the anchor bracket 4. Each positioning pin 9 of the anchor bracket 4 is connected to the hole position under the main frame 1 of a box. Each anchor bracket 4 supports 4 boxes. Figure 7 As shown, before the LED modules 5 are installed, the height of the main frame 1 of each box is adjusted to be level, thereby avoiding the disadvantage of disassembling the entire box during installation or maintenance.

[0029] The LED floor screen cabinet structure uses magnetic attraction to secure the LED module 5. When maintaining the power supply and control board, the LED module 5 can be simply removed by suction, eliminating the need to disassemble the entire cabinet. Furthermore, the force-bearing surface of the LED module 5 is increased from the small area of ​​the magnet to the entire area between the bottom of the bottom shell and the main frame structure 1, preventing damage to the magnet and improving stability.

[0030] The front and rear side parts of each LED floor screen box are equipped with cooling fans through the connection holes 6, which can form a heat dissipation channel with air outlet from the front and air intake from the rear, effectively reducing the heat inside the LED floor screen box, and also effectively reducing the humidity and increasing the service life of the module.
