Description

Technical Field

[0001] This invention belongs to the field of LED display technology, and specifically relates to a rapidly assembled LED display cabinet. Background Technology

[0002] As semiconductor light-emitting devices, LEDs have evolved into flat panel display products, namely LED displays, after significant increases in their emission wavelength range and performance. The assembly unit of an LED display is the display unit cabinet, which is spliced ​​together to form a large LED display screen. To expand the applicability of LED displays and standardize assembly specifications, the connection of regular and irregular, curved and flat LED displays is often involved.

[0003] Die-cast aluminum cabinets are commonly used for LED display screens, but most die-cast aluminum cabinets are enclosed on all four sides, which prevents the heat generated by the LEDs from being dissipated, resulting in a significant reduction in the lifespan of the LED display screen.

[0004] Authorized patent CN105161019B discloses a unit assembly component for an LED display screen. The assembly connection includes a first assembly component on a first mounting rib and a second assembly component on a second mounting rib. The unit assembly component of this invention allows for separate assembly and disassembly, enabling rapid assembly. However, it cannot connect LED display screen cabinets of multiple specifications, i.e., assemble large LED display screens, and it does not solve the problem of rapid heat dissipation for LED display screen cabinets. Summary of the Invention

[0005] The purpose of this invention is to provide an LED display screen that can achieve multiple assembly methods and has good heat dissipation, so as to solve the problems in the background art.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A rapidly assembled LED display cabinet includes longitudinal beams, transverse beams, and a peripheral frame. The peripheral frame is provided with arc-shaped surface connection structures and straight surface connection structures.

[0008] The arc-shaped surface connection structure includes an arc-shaped mounting component on one side of the housing unit and an arc-shaped locking component on the opposite side of the housing unit; the arc-shaped mounting component includes a slider, a first slide block, and a first connecting part; the arc-shaped locking component includes a semi-arc-shaped fixing component, a second slide block, and a second connecting part; the arc-shaped locking component and the semi-arc-shaped fixing component engage to realize the connection of the arc-shaped LED surface;

[0009] The flat surface connection structure includes a universal joint on one side of the housing unit and a reverse universal joint on the opposite side of the housing unit; the universal joint is obtained by connecting the A-axis tube to the B-axis tube in sequence, and the reverse universal joint is obtained by connecting the B-axis tube to the A-axis tube in sequence; the A-axis tube has a concave section inside, and the B-axis tube has a convex section outside. The universal joint and the reverse universal joint are snapped together using a concave-convex structure to achieve the connection of the flat surface LED.

[0010] The straight pipe channel of the universal joint itself is configured as an air supply pipe, and the port is an elliptical air outlet.

[0011] As a further embodiment of the present invention, both the first slide of the arc-shaped mounting member and the second slide of the arc-shaped locking member are provided with arc-shaped grooves in the middle, and the slider can slide freely on the arc-shaped grooves.

[0012] As a further embodiment of the present invention, the elliptical air vent can be replaced with any air vent shape that has a larger cross-sectional area than the rectangular air vent.

[0013] As a further embodiment of the present invention, a ventilation duct is provided inside the LED display cabinet, and the ventilation duct and the universal joint are arranged on the same side.

[0014] As a further embodiment of the present invention, the longitudinal beams and transverse beams are connected within the box body to form a cross-shaped intermediate connecting bracket, a T-shaped side transverse beam connecting bracket, and an inverted L-shaped longitudinal and transverse beam connecting bracket.

[0015] As a further aspect of the present invention, the connection method is specifically a threaded connection.

[0016] As a further aspect of the present invention, the LED display screen housing is made of die-cast aluminum and is formed by integral die-casting aluminum.

[0017] 1. The LED display cabinet unit adopts a flat-plane connection method, and the flat-plane connection structure is set as a universal joint; the straight pipe channel of the universal joint itself is set as an air supply duct, thus combining the multiple effects of flat section connection, deflection, and heat dissipation. For areas with many electronic components inside the LED display cabinet, due to the large number of heat sources, air ducts are set on the same side of the universal joint to achieve heat dissipation and smooth transfer in key heat dissipation areas.

[0018] 2. At the end of the straight duct, the original rectangular air outlet is replaced with an elliptical air outlet, thereby increasing the area of ​​the air outlet. Because the duct has friction resistance, the air velocity decreases towards the end of the outlet, so increasing the area of ​​the air outlet helps to dissipate heat smoothly inside the LED display cabinet.

[0019] 3. The curved surface of the LED display cabinet unit adopts a curved surface connection structure. The sliding of the slider in the curved groove increases the connection margin of the LED display cabinet unit.

[0020] 4. The LED display screen designed in this invention uses a die-cast aluminum casing. Due to its stable molding and accurate machining, the die-cast aluminum casing ensures the precision of its external dimensions and other mating dimensions. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, those skilled in the art can make inventive decisions without making creative contributions.

[0028] All other embodiments obtained under the premise of labor are within the scope of protection of this invention.

[0029] This invention provides a rapidly assembled LED display cabinet. The cabinet is made of die-cast aluminum and comprises several cabinet units. Eight LED panels are installed in one cabinet.

[0030] On the body, a display module is formed.

[0031] See Figure 1The LED display cabinet has a rectangular frame, composed of longitudinal and transverse beams. The longitudinal and transverse beams connect in the middle to form a cross-shaped central support, and at the corners, they form T-shaped or inverted L-shaped side transverse beam support brackets. The longitudinal and transverse beams are connected by a plug-in method to form the LED display cabinet mounting frame.

[0032] The LED display screen is surrounded by mounting sections, each consisting of a first, second, third, and fourth splicing component. The first and third splicing components are vertically aligned and arranged perpendicularly; the second and fourth splicing components are horizontally aligned and arranged parallel to each other. All surrounding longitudinal and transverse beams and the LED display screen mounting sections are connected using bolts and nuts.

[0033] The curved surface connection device and the flat surface connection device of the cabinet unit are installed on the LED display installation section.

[0034] See Figure 2 and Figure 3 For the arc-shaped surface connection device of the housing unit, an arc-shaped mounting part 1 is installed on one side of the housing unit, and an arc-shaped locking part 2 is provided on the opposite side of the housing unit. The arc-shaped mounting part 1 includes, from top to bottom, a slider 11, a first slide block 12, and a first connecting part 13; the first slide block 12 has an arc-shaped groove in the middle, and the slider 12 is installed on the arc-shaped groove, allowing the slider 12 to slide freely on the arc-shaped groove. The first connecting part 13 has threaded holes, and threaded holes are opened around the perimeter of the housing, allowing bolt and nut connection with the first connecting part 13 via custom-made screws. For the arc-shaped locking part 2, from top to bottom, it includes a semi-arc-shaped fixing part 21, a second slide block 22, and a second connecting part 23. The second slide block 22 has an arc-shaped groove in the middle, and the semi-arc-shaped fixing part 21 is fixed on the arc-shaped groove. The second connecting part 23 and the perimeter of the housing are connected by bolts and nuts. When installing the enclosure, the slider 11 of the arc-shaped mounting piece 1 and the semi-arc-shaped fixing piece 21 of the arc-shaped locking piece 2 are engaged to achieve the connection of the arc-shaped surfaces.

[0035] For the flat-plane connection of the enclosure units: a universal joint assembly structure is installed on one side of the enclosure unit. The universal joint, as a flexible component, can rotate without lubrication; with the help of the integrated cavity, rotation in two directions can be achieved. As a flat-plane connection device for the enclosure units, the universal joint can connect two enclosures...

[0036] The rotation of the unit at different angles enables the LED display screen to be assembled and connected in different orientations.

[0037] See Figure 4 and Figure 5The universal joint 3 includes an A-axis tube and a B-axis tube. The A-axis tube has a concave section inside, and the B-axis tube has a convex section outside. On the opposite side of the universal joint, the housing unit has a reverse universal joint 4. The connection order of the A-axis tube and the B-axis tube is changed, so that the universal joint 3 and the reverse universal joint 4 can be snapped together using a concave-convex structure to achieve a turning connection on the flat surface of the housing unit.

[0038] For universal joint 3 and reverse universal joint 4, their straight pipe channels are configured as air supply ducts, while the coupling ports are configured as elliptical air outlets. Because the air supply duct has frictional resistance, the air velocity decreases towards the end of the outlet. Therefore, the original rectangular air outlet is replaced with an elliptical air outlet, thereby increasing the outlet area. The elliptical air outlet has a sudden change in direction, significantly increasing the air velocity at the outlet. The elliptical air outlet can be replaced with any air outlet shape that increases the cross-sectional area compared to the rectangular air outlet, such as a spherical air outlet, etc.

[0039] Because LED display cabinets contain numerous electronic components, including LEDs, driver ICs, and switching power supplies, low thermal resistance pathways, i.e., ventilation ducts 5, are necessary to address the high heat sources within the LED display cabinet. To ensure efficient heat transfer, universal joints 3 or reverse universal joints 4 are installed on the same side as the ventilation duct 5, connecting the ventilation duct and its opening to facilitate heat dissipation.

[0040] The LED display cabinet is made of die-cast aluminum, which is formed from aluminum ingots and alloy materials melted in a furnace and then die-cast in a die-casting machine. Die-cast aluminum cabinets have high hardness and strength, and are stable in forming.
