[0041] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail 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. On the contrary, 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.

[0042] Example:

[0043] Reference Figures 1 to 3 This embodiment provides a thin and light LED display screen, which includes a plurality of display boxes. The display box includes a box body, an LED display module 1 installed on the front of the box body, and a control module 3 installed in the inner space of the box body.

[0044] See also Figure 4 The box body includes a magnetic front plate 21, a box frame 23 and a rear cover plate 22 from front to back. The magnetic front plate 21 and the rear cover plate 22 are respectively covered on the front and back of the box frame 23. The inner side of the box frame 23 is provided with a receiving cavity for receiving the control module 3. The magnetic front plate 21 and the rear cover plate 22 are installed with the box frame 23 by bolt connection, bonding, clamping, etc.

[0045] See also Figure 4 and Figure 5, wherein the accommodating cavity includes a cavity bottom plate 252 and a cavity cover plate 251 that cooperate with each other, and the accommodating cavity is placed in the space between the magnetic front plate 21 and the rear cover plate 22. The accommodating cavity is arranged along the length direction of the box body and is connected to the box frame 23. The control module 3 is installed in the accommodating cavity and is electrically connected to the LED display module 1 to conduct electricity and signals. The control module 3 includes an adapter board 32, a control card 31 and a power circuit board 33. The control card 31 is installed on the front of the adapter board 32, and the power circuit board 33 is stacked on the back of the adapter board 32, and the two are fixed to the bottom of the accommodating cavity by bolts.

[0046] Compared with the design of setting the control box on the back of the box in the existing technology, the present application sets a accommodating cavity 25 in the box body, and installs the control module 3 in the accommodating cavity 25 in the box body, which greatly reduces the thickness of the display box and solves the technical problems of the existing LED display screen with large overall thickness and high production cost.

[0047] See also Figure 4 Furthermore, the adapter plate 32 and the power circuit board 33 are in the shape of long strips and are placed along the length direction of the accommodating cavity. Compared with the existing power supply with a shell, the present application only retains the power circuit board 33 and sets it in the shape of a long strip, which saves more space and helps to reduce the thickness of the box body.

[0048] Continue reading Figure 4 In some feasible solutions, the magnetic front plate 21 is provided with an avoidance hole 211 at a position relative to the cavity cover 251, and the cavity cover 251 is installed in the avoidance hole 211, further reducing the thickness of the box. The cavity cover 251 is installed in the avoidance hole 211 in an existing detachable manner, such as bolt connection, clamping, etc., for easy maintenance. A plurality of light board connectors 321 are provided on the front of the adapter plate 32, and the cavity cover 251 is provided with an avoidance hole 2511. The light board connector 321 extends from the avoidance hole 2511 for plugging and connecting with the LED light board 11.

[0049] See also Figure 1 , Figure 3 and Figure 6As a feasible solution, a connection lock for splicing with adjacent boxes is installed in the box frame 23. The connection lock includes an upper and lower lock and a left and right lock. The upper and lower locks include a first locking rod 2611 placed in the top edge of the box frame 23 and a first tightening screw 2612 placed in the bottom edge. The first locking rod 2611 is provided with an arc groove that cooperates with the first tightening screw 2612. The first locking rod 2611 and the first tightening screw 2612 are perpendicular to each other. The first tightening screw 2612 extends from the front of the box frame 23 into the bottom edge and is perpendicular to the surface of the box frame 23. The left and right locks include a second locking rod 2621 and a second tightening screw 2622 located on one side, and a gourd-shaped hole 2623 located on the other side. One end of the second locking rod 2621 extends into the box frame 23 and is provided with an arc groove that matches the second tightening screw 2622. The other end of the second locking rod 2621 extends from the box frame 23 and is provided with a clamping joint that can be clamped in the small hole part of the gourd-shaped hole 2623. The second locking rod 2621 and the second tightening screw 2622 are arranged perpendicular to each other. The second tightening screw 2622 extends from the front of the box frame 23 into the side and is perpendicular to the surface of the box frame 23. In the process of splicing the boxes, the first and second tightening screws 2612 and 2622 are screwed from the front of the box frame 23 to make them contact the side wall of the arc groove of the corresponding lock rod, so that the locking, unlocking and fine-tuning of the splicing gap between the adjacent boxes can be realized, and the splicing of two display boxes can be realized, and it can be operated by one person. Therefore, the setting of the connecting lock makes full use of the space of the box frame 23, does not increase the thickness of the box body, and the thickness of the display box is smaller.

[0050] See also Figure 4 In actual application, the box body also includes a longitudinal beam 24, which is fixedly installed on the inner side of the box frame 23 and vertically connected to the accommodating cavity. The accommodating cavity and the longitudinal beam 24 constitute the reinforcement structure of the box body. The longitudinal beam 24 is hollow, and the box frame 23 is provided with a wire hole 231 at a position opposite to the longitudinal beam 24, which is convenient for the storage and arrangement of cables. The front and back sides of the box frame 23 and the front and back sides of the longitudinal beam 24 are both provided with a plurality of strip grooves along their length direction.

[0051] See also Figure 4 In some feasible solutions, the LED display module 1 includes an LED light board 11 and a magnetic bracket 12 from front to back, and a magnet is installed on the magnetic bracket 12. The LED display module 1 is magnetically matched with the magnetic front plate 21 of the box body.

[0052] See also Figure 2 In this embodiment, two LED display modules 1 are installed on each display box, one of which is not shown in the figure. In actual application, the number of LED display modules 1 installed on each display box is set according to actual conditions.
