[0031] Please see Figures 1 to 4The support mechanism for LED curved screens in this embodiment includes: a first support structure 1 and a curved screen support body 2 that is magnetically connected and fixed to the first support structure 1.

[0032] The curved screen support body 2 of this embodiment includes: a first support base plate 21 with a recessed groove in the middle, and a curved PCB lamp board 23 fixed to the first support base plate 21 by copper strips 22 on both sides. Specifically, a plurality of protrusions a1 are provided on the side of the PCB lamp board 23 facing the first support base plate 21, and fixing posts a2 pass through the first support base plate 21 and the copper strips 22 and are fixed to the protrusions a1; a buffer ring is sleeved on the fixing post a2. In this embodiment, the copper strips 22 are segmented copper strips, and a plurality of copper strips 22 are respectively installed on both sides of the PCB lamp board 23 along its length to fix the PCB lamp board 23 to the first support base plate 21. Further, a snap-fit ​​seat is formed on the groove of the first support base plate 21 facing the PCB lamp board 23 to snap onto the protrusions a1, and the corresponding protrusions a1 on the PCB lamp board 23 are snapped into the snap-fit ​​seat and fixed by screws with buffer rubber rings. In addition, a conductive element b1 protrudes from the side of the copper strip 22 on the PCB light board 23, penetrating the first support base plate 21 during installation. A magnetic suction element b2 is mounted on the first support base plate 21. Specifically, a magnet sleeve for fixing the magnetic suction element b2 is injection molded on the first support base plate 21, and the magnetic suction element b2 is installed inside the magnet sleeve. More specifically, the substrate thickness of the PCB light board 23 is 0.4mm. This structure allows the PCB light board 23 of this product to achieve minimum tension while meeting bending requirements. At the same time, the copper strip 23 is used as a fixing medium between the PCB light board 23 and the first support base plate 21, thereby changing the point tension of the fixing point of the first support base plate 21 to the surface tension of the PCB light board 23, thus making the product uniformly stressed and effectively preventing the risk of product deformation. At the same time, this product can achieve a minimum arc length of 125mm for the PCB light board, thereby effectively improving the 3D effect when the product is in use. It should be noted that the conductive component b1 is an electric foam, and the magnetic component b2 is a magnet.

[0033] The first support structure 1 in this embodiment includes: a second base plate 11 magnetically connected to both sides of the first support base plate 21 and having a recessed receiving groove in the middle; a control circuit board module 12 installed in the receiving groove and connected to the PCB lamp board 23; and a plurality of PG heads 13 penetrating the second base plate 11 and connected to the control circuit board module 12. The PCB lamp board 23 and the control circuit board module 12 are connected by a connector c1 penetrating the first support base plate 21. Specifically, the control circuit board module 12 includes: a first circuit board d1 stacked on the other side of the first support base plate 21 and connected to the PCB lamp board 23 through the connector c1; and a second circuit board d2 connected to the first circuit board d1 with a gap and disposed on the second base plate 11. This structure allows the product to achieve a maximum stacking effect, thereby making the overall structure of the product compact. Furthermore, both ends of the second base plate 21 are equipped with magnetic components e1 and glass beads e2. The magnetic components e1 facilitate the installation of the upper and lower housings of the product, while the glass beads e2 facilitate alignment during installation, further enhancing the ease of product assembly. Moreover, this product uses a PG connector 13 for power and signal connection with the left and right housings, overcoming the large size of existing products. The test button is centrally mounted on the first support structure 1, improving the product's aesthetics without affecting testing.

[0034] As can be seen from the above description, the support mechanism of this product for LED curved screens, through reasonable structural design, makes the product easy to assemble and disassemble, with a minimum curved arc length of 125mm, effectively improving the 3D effect when the product is in use, while also effectively improving the compactness and aesthetics of the product design.
