[0002] Indoor COB displays occupy an important position in the current display technology field, and their excellent optical performance and reliability are widely recognized. However, in the existing indoor COB display structure design, there are some problems in the design of the cabinet.

[0003] Traditional indoor COB display cabinets are usually made of multiple panels, which are relatively complex and difficult to manufacture. Due to the thick overall frame of the cabinet, the cabinet is heavy and bulky, making it difficult to install and carry.

[0004] Furthermore, heat dissipation is a key consideration in indoor COB display designs, as the heat generated by COB panels must be dissipated promptly to ensure proper operation and extend their lifespan. However, existing cabinet designs often lack effective heat dissipation structures, resulting in a limited contact area between the COB panels and the cabinet. This results in less than ideal heat dissipation, easily causing the COB panels to heat up, reducing the performance and lifespan of the display. Utility Model Content

[0031] The embodiment of the utility model proposes a die-cast box for an indoor COB display screen, which is integrally formed and includes a back panel and side panels arranged around the edges of the back panel; wherein, the outer walls of the side panels are provided with a plurality of box adjustment platforms, the thickness of the box adjustment platforms is greater than the thickness of the side panels, and the rear side edges of the box adjustment platforms extend into a whole, and the inner sides of the side panels are provided with mounting portions at corresponding positions of the box adjustment platforms, and the mounting portions are provided with threaded adjustment holes that penetrate the side panels, which are used to cooperate with adjustment pieces to adjust the splicing gaps of adjacent die-cast boxes; the outer walls of the side panels are provided with a plurality of box adjustment platforms, the thickness of the box adjustment platforms is greater than the thickness of the side panels, and the inner sides of the side panels are provided with mounting portions with threaded adjustment holes, which can make the overall thickness of the frame of the die-cast box smaller and thinner, and also ensure that the die-cast box has sufficient strength, so that it is not easy to deform during the splicing process, and the working performance is stable and reliable, thereby solving the technical problem that the existing indoor COB display screen box is relatively bulky.

[0032] To better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0033] Example:

[0034] Reference Figure 1 and Figure 2 This embodiment provides a die-cast box for an indoor COB display screen. The die-cast box is integrally formed and includes a back panel 100 and side panels 200 arranged around the edges of the back panel 100.

[0035] See Figure 2 、 Figure 4 and Figure 5 The outer wall of the side panel 200 is provided with several box adjustment platforms 2. The thickness of the box adjustment platform 2 is greater than the thickness of the side panel 200, and the rear edge of the box adjustment platform 2 extends into a whole. The inner side of the side panel 200 is provided with a mounting portion at the corresponding position of the box adjustment platform 2. The mounting portion is provided with a threaded adjustment hole 21 that passes through the side panel 200, which is used to cooperate with the adjustment member to adjust the gap between adjacent die-cast boxes.

[0036] In other words, a box adjustment platform 2 is provided on the outer side of the side panel 200, and a corresponding mounting portion is provided on the inner side. The threaded adjustment hole 21 passes through the box adjustment platform 2 and extends into the mounting portion, ensuring that the side panel 200 of the die-cast box will not be deformed during subsequent splicing operations, and the side panel 200 is thinner than the existing box.

[0037] See Figure 1 and Figure 5 In some feasible solutions, connecting piece mounting angles 1 are provided at four right-angle positions of the back panel 100. The connecting piece mounting angles 1 are right-angled and extend and thicken toward the front and back directions respectively, providing a more reliable fulcrum for the connecting piece body, making the installation of the connecting piece body more stable and the die-cast box less likely to deform.

[0038] It should be noted that in order to reduce the weight of the die-cast box and make it thinner, the thickness of the side panel 200 and the back panel 100 is very small. However, the mechanical strength of the die-cast box must meet the requirements and ensure that the die-cast box does not deform during splicing, installation and use. Therefore, the threaded adjustment hole 21 provided on the side panel 200 must be provided on the mounting part, the positioning hole 5 is provided on the box adjustment platform 2 at the right angle of the box, the connecting piece installation angle 1 provided on the back panel 100 is thickened, and the edges around the wire hole 4 are also thickened.

[0039] See Figure 5 In actual operation, a first connection hole 11 is provided at the intersection of the two sides of the connecting plate mounting angle 1, and second connection holes 12 are provided on both sides. The diameter of the first connection hole 11 is larger than that of the second connection hole 12. The first connection hole 11 can adapt to mounting screws with larger diameters, which improves the installation effect.

[0040] See Figure 1 In the actual production process, a plurality of first ridges 3 for heat dissipation are provided on the back plate 100 to increase the heat dissipation area of ​​the die-cast box and improve the heat dissipation efficiency.

[0041] See Figure 2 and Figure 5 In some feasible solutions, a plurality of second ridges 6 are provided on the four edges of the front side panel 200. The second ridges 6 are in a right-angle shape and are not connected to each other. Therefore, when the COB light board is installed on the die-cast box, a plurality of heat dissipation gaps will be formed between the two, which facilitates heat exchange inside and outside the die-cast box and improves the heat dissipation rate. At the same time, the second ridges 6 also ensure that there is sufficient contact area between the COB light board and the die-cast box, which helps to conduct heat to the back panel 100.

[0042] See Figure 3 and Figure 5Furthermore, the front of the back panel 100 is evenly provided with third ridges 8 for receiving and installing the COB light board. The third ridges 8 are in a right-angled shape or a strip shape, and four right-angled third ridges 8 are combined into a cross-shaped structure to support the right-angle positions of four adjacent COB light boards. The back panel 100 is provided with a magnet mounting column 7 at a position relative to each second ridge 6, and a magnet mounting column 7 is provided at each right-angled third ridge 8. A magnet mounting column 7 is provided on both sides of the strip-shaped third protrusion, and a magnet sheet is installed on the magnet mounting column 7, which is magnetically matched with the COB light board. The COB light board and the die-cast box are installed together through the magnet sheet, the second ridge 6, and the third ridge 8, and are in contact for heat conduction, so the COB light board has better heat dissipation.

[0043] In this embodiment, a die-cast housing is used with eight COB light panels, so three cross-shaped structures are provided in the middle of the back panel 100. Second ridges 6 are provided along the four right angles of the side panels 200, and a pair of second ridges 6 are provided at other locations on the side panels 200, corresponding to the right angles of two adjacent COB light panels. Third protrusions, either strip-shaped or right-angled, are provided at various points on the front of the back panel 100. Depending on whether the third protrusions are provided at the side or right angles of the COB light panels, these protrusions correspond to each other. This reduces the material required to produce the die-cast housing, saving costs and reducing the weight of the die-cast housing.

[0044] See Figure 3 Under the premise of controlling the thickness and weight of the die-cast box, in order to improve the mechanical strength of the die-cast box, the front of the back plate 100 is provided with transverse reinforcing ribs 91, longitudinal reinforcing ribs 92 and diagonal reinforcing ribs 93. The diagonal reinforcing ribs 93 are distributed on both sides of the die-cast box and are located on the diagonal lines of the rectangle formed by the transverse reinforcing ribs 91 and the longitudinal reinforcing ribs 92.
