[0030] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] In the description of this application, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] As shown in Figures 1 to 3, one embodiment of this application provides a unit screen, including a display module 200 and a cabinet frame of the unit screen. The cabinet frame of the unit screen includes a frame body 100, which includes multiple fasteners 2 and multiple carbon fiber square tubes 1. The frame body 100 is in a closed loop shape and has multiple corners. A fastener 2 is provided at each corner. A carbon fiber square tube 1 is fixedly connected between two adjacent fasteners 2. The fasteners 2 are fixed to the back of the display module 200 of the unit screen.

[0034] As shown in Figure 3, the carbon fiber square tube 1 is a hollow square tube. The outer circumference of the carbon fiber square tube 1 includes a first side 11, a second side 12, a third side, and a fourth side. The first side 11 and the third side are opposite and parallel, the second side 12 and the fourth side are opposite and parallel, the first side 11 and the second side 12 are perpendicularly connected or connected by rounded corners, and the third side and the fourth side are perpendicularly connected or connected by rounded corners.

[0035] Because the carbon fiber square tube 1 is made of carbon fiber, it is lightweight and high-strength. While ensuring the overall high strength of the cabinet frame, the weight of the entire cabinet frame is reduced, thereby reducing the weight of the unit screens, minimizing the impact of the cabinet frame on the installation limit of the display module 200, reducing the labor intensity of hoisting, and lowering the installation difficulty. Furthermore, the square carbon fiber square tube 1 has a larger load-bearing area and higher load-bearing capacity, allowing the cabinet frame to support larger display modules 200.

[0036] In one embodiment, the first side 11 and the third side are rectangles of the same size, and the second side 12 and the fourth side are rectangles of the same size; the first side 11 faces the back of the display module 200 of the unit screen or the second side 12 faces the back of the display module 200 of the unit screen.

[0037] If the width A of the first side 11 is greater than the width B of the second side 12, then the range of B / A is 0.6 to 0.75. The length of the first side 11 and the length of the second side 12 are the dimensions of the carbon fiber square tube 1 in its extension direction.

[0038] For carbon fiber square tube 1, the closer the B / A ratio is to 1, the greater the weight and volume of carbon fiber square tube 1 per unit length, the larger the load-bearing area, and the larger the space occupied; the smaller the B / A ratio, the smaller the load-bearing area and the smaller the space occupied per unit length. Therefore, in this application, the B / A ratio of the carbon fiber square tube 1 is designed to be in the range of 0.6 to 0.75, so that the box frame has the advantages of being both lightweight and having a large load-bearing capacity.

[0039] In one embodiment, as shown in Figures 1 and 3, the second side 12 of the carbon fiber square tube 1 faces the back of the display module 200 of the unit screen. The second side 12 bears the force transmitted from the display module 200 to the carbon fiber square tube 1 through the fastener 2. The width B of the second side 12 is smaller than the width A of the first side 11, and the area of ​​the second side 12 is relatively small. Under the same force, the carbon fiber square tube 1 has higher bending strength and better load-bearing capacity.

[0040] In one embodiment, as shown in Figures 2 and 3, the first side 11 and the second side 12 are transitioned by a first rounded corner, and the third side and the fourth side are transitioned by a second rounded corner; the outer radius of the first rounded corner and the second rounded corner is R, and the wall thickness of the carbon fiber square tube 1 is t, then: 2t < R < B / 3.

[0041] The adjacent walls of the carbon fiber square tube 1 are transitioned by rounded corners to avoid stress concentration and improve the structural strength of the carbon fiber square tube 1.

[0042] In one embodiment, A = 21, B = 15, t = 1.5, and R = 4.5.

[0043] Of course, in actual design, the dimensions of A, B, t, and R of the carbon fiber square tube 1 can be adjusted according to load-bearing requirements and installation space requirements. Preferably, the ratio of B to A is between 0.6 and 0.75, and 2t < R < B / 3. For example, B / A can be 0.6, 0.65, 0.7, or 0.75. Alternatively, B / A can be 0.5, 0.55, 0.8, or 0.9, or A = B, B > A, and the dimensions of t and R can be R ≤ 2t or R ≥ B / 3.

[0044] In other embodiments, the first side 11 of the carbon fiber square tube 1 may face the back of the display module 200 of the unit screen.

[0045] In one embodiment, as shown in FIG1, the fastener 2 has two vertically connected connecting ends 21, and the connecting ends 21 are provided with mounting holes, the cross-sectional shape of which is adapted to the cross-sectional shape of the carbon fiber square tube 1.

[0046] One end of the carbon fiber square tube 1 is inserted into the mounting hole of a fastener 2, and the other end of the carbon fiber square tube 1 is inserted into the mounting hole of another adjacent fastener 2.

[0047] The cabinet frame is an assembled structure. When transporting the cabinet frame, each part of the cabinet frame is transported to the place of use. Then, the cabinet frame is assembled on site. Specifically, the two ends of the carbon fiber square tube 1 are inserted into the mounting holes of the connection ends 21 of two adjacent fasteners 2 to assemble a closed frame body 100. Then, the fasteners 2 are fixed to the back of the display module 200.

[0048] Because the outer contour of the carbon fiber square tube 1 is square, when the carbon fiber square tube 1 is inserted into the mounting hole, the mounting hole and the carbon fiber square tube 1 can guide each other to position the carbon fiber square tube 1 and prevent it from rolling or misaligning. Moreover, the carbon fiber square tube 1 and the fastener 2 are assembled by insertion, which is simple and improves installation efficiency.

[0049] In one embodiment, the carbon fiber square tube 1 is bonded to the fastener 2, which facilitates installation, ensures a firm connection, and prevents loosening.

[0050] In one embodiment, as shown in Figure 1, the frame body 100 is square, with four carbon fiber square tubes 1 and four fasteners 2; two of the carbon fiber square tubes 1 extend along a first direction, and the other two extend along a second direction; wherein the first direction is perpendicular to the second direction. In Figure 1, D1 represents the first direction, and D2 represents the second direction.

[0051] The unit screen's cabinet frame also includes a main beam 3 extending along the second direction. Both ends of the main beam 3 are provided with guide holes that penetrate along the first direction. A carbon fiber square tube 1 extending along the first direction passes through the corresponding guide hole. The cross-sectional shape of the guide hole is adapted to the cross-sectional shape of the carbon fiber square tube 1.

[0052] The main beam 3 is connected between the carbon fiber square tubes 1 on opposite sides of the frame body 100 along the second direction, which can improve the structural strength of the box frame, so that the box frame can support a heavier display module 200.

[0053] In other embodiments, the frame body 100 can be a triangle, rhombus, hexagon, etc.

[0054] In one embodiment, as shown in FIG1, the unit screen further includes a power module 8, which is mounted on the main beam 3 to utilize existing structural components on the box frame to install the power module 8, eliminating the need for additional mounting components for installing the power module 8 and simplifying the structure of the box frame.

[0055] In one embodiment, a connecting lock 4 and a locking part 5 are also included. The connecting lock 4 is installed on a fixing member 2 on one side of the frame body 100 along the first direction, and the locking part 5 is installed on a fixing member 2 on the other side of the frame body 100 along the first direction.

[0056] One of the unit screens has a connecting lock 4 that locks to the locking part 5 of the adjacent unit screen's cabinet frame, temporarily fixing the two adjacent unit screens together. Multiple unit screens can then be assembled into the desired display screen in this manner. When the display screen needs to be disassembled, the connecting lock 4 of one unit screen is released from the locking part 5 of the adjacent unit screen, allowing the two adjacent unit screens to separate easily.

[0057] Furthermore, the connecting lock 4 and the locking part 5 are set on the fixing part 2 at the corner of the frame body 100, so that the two ends of the adjacent carbon fiber square tubes 1 of the two adjacent box frames are locked, making the connection more secure.

[0058] In one embodiment, a handle 31 is provided at the upper end of the main beam 3 to facilitate the transportation of the unit screen.

[0059] In one embodiment, as shown in FIG1, it further includes a first positioning bracket 6 and a second positioning bracket 7. The first positioning bracket 6 is provided with a first through hole extending along a second direction, and the second positioning bracket 7 is provided with a second through hole extending along the second direction. The cross-sectional shapes of the first through hole and the second through hole are adapted to the cross-sectional shape of the carbon fiber square tube 1.

[0060] The carbon fiber square tube 1 extending in the second direction and close to the first positioning bracket 6 is inserted through the first through hole, and the carbon fiber square tube 1 extending in the second direction and close to the second positioning bracket 7 is inserted through the second through hole, so as to avoid damaging the structure of the carbon fiber square tube 1.

[0061] The first positioning bracket 6 is provided with a positioning protrusion protruding to the side away from the second positioning bracket 7, and the second positioning bracket 7 is provided with a positioning groove 71 with an opening facing away from the first positioning bracket 6. The positioning protrusion of the cabinet frame of one unit screen is used to be engaged in the positioning groove 71 of the second positioning bracket 7 of the cabinet frame of the adjacent unit screen.

[0062] When assembling two adjacent unit screens, first insert the positioning protrusion on the first positioning bracket 6 of one unit screen into the positioning groove 71 on the second positioning bracket 7 of the adjacent unit screen, and then lock the connecting lock 4 of the unit screen to the connecting part of the adjacent unit screen.

[0063] The snap-fitting of the positioning protrusion and the positioning groove 71 can initially locate the positions of two adjacent unit screens, improve the positioning accuracy of the adjacent unit screens, facilitate the subsequent connection and fixation of the two unit screens, reduce the installation difficulty, and make the connection between the two adjacent unit screens more stable.

[0064] In one embodiment, as shown in FIG1, the fixing member 2 further includes a connecting post 22. The connecting post 22 is disposed on the side of the fixing member 2 facing away from the display module 200. The connecting post 22 is provided with a connecting hole for connecting the steel structure at the required installation position of the display screen to fix the unit screen at the required installation position.

[0065] In one embodiment, two fixing members 2 located on one side of the frame body 100 along the second direction are provided with first positioning seats 23, and two fixing members 2 located on the other side of the frame body 100 along the second direction are provided with second positioning seats 24. The first positioning seats 23 are provided with positioning pins extending away from the first positioning seats 23, and the second positioning seats 24 are provided with positioning holes opening away from the first positioning seats 23. When multiple unit panels are assembled along the second direction, the positioning pin on one unit panel is inserted into the positioning hole of an adjacent unit panel.

[0066] In one embodiment, the first direction is the left-right direction. Two fixing members 2 located on the left side of the frame body 100 are provided with connecting locks 4, and two fixing members 2 located on the right side of the frame body 100 are provided with locking parts 5. Two unit screens are assembled along the left-right direction, and the connecting lock 4 of one unit screen is locked with the locking part 5 of the other unit screen.

[0067] In other embodiments, the fastener 2 and the carbon fiber square tube 1 can be fixed by welding or by flange connection.

[0068] In other embodiments, the connecting lock 4 and the locking part 5 can be fixed to the carbon fiber square tube 1.

[0069] In addition, one embodiment of this application also provides a cabinet frame for a unit screen, the structure of which is the same as the cabinet frame of the unit screen in any of the above embodiments, and will not be described again here.

[0070] In addition, one embodiment of this application also provides a display screen, which is assembled from multiple unit screens as described in any of the above embodiments.
