[0050] In order to better understand the above technical solution, the exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the 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. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to be able to convey the scope of the present invention completely to those skilled in the art.

[0051] Embodiment 1:

[0052] Reference Figure 1 and Figure 3 , this embodiment 1 provides a carbon fiber LED display screen based on an integrated module back frame, which includes a display module, a carbon fiber box 3, a control box 4 and a back bracket 5, the display module can be detachably mounted on the front of the carbon fiber box 3, the control box 4 can be detachably mounted on the middle of the back of the carbon fiber box 3, and is connected with the display module electrical signal, and the back bracket 5 can be detachably mounted on the back of the carbon fiber box 3. Multiple carbon fiber LED display screens are spliced ​​to form a large LED screen.

[0053] See also Figure 4 , wherein the back support 5 includes a first carbon fiber tube 51 and a second carbon fiber tube 52 arranged in parallel in the longitudinal direction, the two first carbon fiber tubes 51 are connected together by two fixed cross bars 53, the second carbon fiber tube 52 is connected to the rear side of the fixed cross bar 53, and the front side of the fixed cross bar 53 is provided with a back support docking lock 56 for locking to the carbon fiber box 3, therefore, a cross-shaped connection structure is formed between the first carbon fiber tube 51 and the second carbon fiber tube 52, and there are two cross-shaped structures, so that the back support 5 becomes an independent and stable whole. The second carbon fiber tube 52 is located behind the two first carbon fiber tubes 51, and the connecting line of the three is an isosceles triangle, so the structure of the back support 5 is more stable and the force is more balanced. The upper and lower ends of the first carbon fiber tube 51 are provided with connecting devices 511, which are used to be detachably connected with the hoisting locking mechanism 31 of the carbon fiber box 3.

[0054] See also Figure 1 and Figure 6 In some feasible schemes, the lifting locking mechanism 31 includes an upper locking unit 311 and a lower locking unit 312, which are correspondingly installed at the upper and lower ends of the carbon fiber box 3. The lower end of the upper locking unit 311 is extended downward to form a first connecting portion 3111, and the first connecting portion 3111 is detachably connected to the upper connecting device 511. The upper end of the lower locking unit 312 is provided with a second connecting portion 3121, and the second connecting portion 3121 is connected to the lower connecting device 511.

[0055] The ends of the upper locking unit 311 and the lower locking unit 312 are used as one of the connection points of the back bracket 5 and connected through the connecting device 511, so there is no need to change the original structure of the box frame 34, which reduces the manufacturing cost and makes the connection and disassembly operations more convenient. Since the carbon fiber box 3 is provided with the first connecting part 3111, the second connecting part 3121 and the back frame locking hole 344, the back bracket 5 and the display module have two groups of six connection points, and the three connection points of each group are not in the same straight line, so the force is dispersed and the connection is more stable and reliable.

[0056] Furthermore, the two groups of connecting devices 511 distributed up and down are perpendicular to the first connecting portion 3111, the second connecting portion 3121 and the first carbon fiber tube 51 at the same time. The cross section of the connecting device 511 is drum-shaped, one group of opposite sides are parallel to each other, and the other group of opposite sides is arc-shaped. The mounting groove 5110 is located at one end where one of the arc-shaped sides is located, and a plug hole is provided at the other end where the other arc-shaped side is located. The first connecting portion 3111 and the second connecting portion 3121 are inserted into the mounting groove 5110 of the corresponding connecting device 511, and are connected to the mounting groove 5110 by bolts. The upper and lower ends of the first carbon fiber tube 51 are inserted into the plug hole of the corresponding connecting device 511, and are connected together by bolts. Due to the provision of the connecting device 511, the difficulty of the connection operation between the back bracket 5 and the carbon fiber box 3 is greatly reduced, and the contact area at the connection between the two is larger, and the connection is more stable.

[0057] See also Figure 5 The back frame docking lock 56 includes a docking lock shell, a docking lock core and a docking handle 561. The docking lock shell is provided with a sliding window. The docking lock core is slidably installed in the docking lock shell, and its straight-shaped lock protrusion extends from the docking lock shell to lock and cooperate with the back frame lock hole 344 of the carbon fiber box 3. The docking handle 561 is vertically plugged and fixed with the docking lock core and extends from the sliding window. When the docking handle 561 is rotated, it can only move within the range of the sliding window. By rotating the docking handle 561, the docking lock core is driven to rotate, so that the straight-shaped lock protrusion rotates in the back frame lock hole 344, the locking effect of the back frame docking lock 56 on the carbon fiber box 3 is released, and at the same time, the connection relationship between the upper connecting device 511 and the first connecting part 3111 is released, and the connection relationship between the lower connecting device 511 and the second connecting part 3121 is released, so that the back frame 5 can be quickly removed from the box frame 34 as a whole. Conversely, the back frame 5 can be quickly installed as a whole on the back of the box frame 34, and the operation is convenient and fast.

[0058] See also Figure 4 and Figure 5 As a feasible solution, a movable rod 55 is connected to the front side of the second carbon fiber tube 52. The movable rod 55 rotates with the fixed cross bar 53 and is locked together by left and right movable locks 58. Therefore, the relative position of the second carbon fiber tube 52 can be changed according to the actual installation situation, which is more flexible to use.

[0059] See also Figure 4 The upper and lower ends of the second carbon fiber tube 52 are both provided with docking threads 521, and the back bracket 5 also includes a connecting sleeve, and the upper and lower ends of the connecting sleeve are provided with threads for connecting two upper and lower adjacent second carbon fiber tubes 52, so that all the back brackets 5 are connected together in the longitudinal direction to form a supporting whole.

[0060] See also Figure 4 , Figure 5 and Fig. 9 Furthermore, the two first carbon fiber tubes 51 are provided with a lap cross bar 54 at the lower side of the fixed cross bar 53, one end of the lap cross bar 54 is rotatably connected with one first carbon fiber tube 51, and the front and rear sides of the other end thereof are symmetrically provided with lap lock grooves 541, so that the lap cross bar 54 can be lapped and locked with another first carbon fiber tube 51 in the same back bracket 5, and can also be lapped and locked with the first carbon fiber tube 51 of another back bracket 5. Fig. 9 As shown, the overlapping cross bar 54 represented by the solid line connects the two first carbon fiber tubes 51 of the same back bracket 5, while the overlapping cross bar 54 represented by the dotted line connects the first carbon fiber tubes 51 of the adjacent back brackets 5. The overlapping lock groove 541 is a composite groove, including a U-shaped groove and a straight groove. The U-shaped groove is formed by the outer wall of the overlapping cross bar 54 being recessed inward, and the straight groove is arranged above the U-shaped groove and passes through the U-shaped groove. The first carbon fiber tube 51 is provided with a mounting ear adapted to the overlapping lock groove 541. When the overlapping lock groove 541 of the overlapping cross bar 54 and the mounting ear are installed in place, they are locked and fixed by the overlapping lock 57 to prevent the overlapping cross bar 54 from moving left and right.

[0061] The upper and lower adjacent second carbon fiber tubes 52 are threadedly connected by connecting sleeves, the fixed cross bar 53 connects the two first carbon fiber boxes 3 in the same back bracket 5, and the lap cross bar 54 connects the first carbon fiber tubes 51 of the two adjacent back brackets 5, so that the first carbon fiber tubes 51 and the second carbon fiber tubes 52 of all the back brackets 5 are combined into a grid-shaped integrated installation structure, ensuring the stability of the connection of each display module in the longitudinal and transverse directions, and greatly improving the stability and reliability of the screen. The back bracket 5 of the present application is light in weight, and the upper and lower adjacent second carbon fiber tubes 52 are threadedly connected by connecting sleeves, which ensures that the carbon fiber box 3 has sufficient compressive strength when the vertical surface is spliced.

One end of the annular buckle 12 is rotatably connected to the mounting seat on the back of the grille display unit 1, and the other end embraces the longitudinal beam of the carbon fiber box 3 and is clamped together with the snap-fit ​​seat on the grille display unit 1, so that the carbon fiber box 3 and the grille display unit 1 are fixed together. The front mounting magnet 13 and the annular buckle 12 are provided to make the installation of the grille display unit 1 faster, more secure and reliable, and not easy to fall off. The annular buckle 12 can be used as a safety anti-fall buckle to effectively prevent the grille display unit 1 from accidentally falling from the carbon fiber box 3, and can also be used as a handle when disassembling and carrying the grille display unit 1. In addition, when the annular buckle 12 is not needed, it can be directly clamped on the snap-fit ​​seat for storage.
