[0029] The technical solutions in the embodiments of this utility model will now be described with reference to the accompanying drawings.

[0030] refer to Figure 1 One embodiment of the present invention provides a display device 100 including a frame 10, a plurality of display modules 20 mounted on the frame 10, and a power supply box 30 mounted on the frame 10, etc., the power supply box 30 being used to supply power to the display modules 20. In this embodiment, there are 8 display modules 20, mounted on the frame 10 in a 4-row, 2-column arrangement; however, the present invention is not limited to this specific configuration.

[0031] In this embodiment, the display module 20 is an LED display module, including a substrate and an LED display array mounted on the front side of the substrate. The front side of the display module 20 is the light-emitting surface and needs to face the audience when in use. Figure 1 The back side of the substrate is shown schematically.

[0032] In this embodiment, the frame 10 includes four sequentially connected borders 11, with adjacent borders 11 connected by corner brackets 13. The borders 11 and corner brackets 13 are detachably connected, allowing for the selection of appropriate lengths of borders 11 to form a frame 10 of suitable size as needed.

[0033] In this embodiment, the four frame members form a rectangle, namely the top frame, bottom frame, left frame, and right frame. The frame 10 also includes two vertical beams 15 and six horizontal beams 17. The two vertical beams 15 are arranged in parallel, with each end of each beam connected to the top and bottom frame respectively. One vertical beam 15 is connected to the left frame by three horizontal beams 17, and the other vertical beam 15 is connected to the right frame by three horizontal beams 17. The display module 20 is positioned in the corresponding grids defined by the horizontal beams 17. The power supply box 30 is installed on the two vertical beams 15 to supply power to the display module 20.

[0034] refer to Figure 2 After the display device 100 is assembled, the display module 20 covers the front of the frame 10, blocking the frame 10 and the power supply box 30, etc.

[0035] refer to Figure 3 and Figure 4 The frame 10 of the display device 100 is provided with a plurality of connecting portions 18, each connecting portion 18 having a non-circular connecting hole 19. The display module 20 is detachably mounted to the connecting portion 18 via the disassembly structure 50. The connecting portion 18 may be integrally provided to the frame 10, for example, as part of the vertical beam 15, or it may be a component additionally connected to the frame.

[0036] refer to Figure 5 and Figure 6The power supply box 30 is mounted to the vertical beam 15 via a connecting plate 39. The power supply box 30 is elongated and has a cable 37 at one end for connecting to an external power source, etc.

[0037] In this embodiment, the power supply box 30 includes a bottom cover 31 and a top cover 33, with the top cover 33 installed at the open end of the bottom cover 31. One side of the top cover 33 is rotatably mounted to one side of the bottom cover 31 via several hinges 35, and the other side of the top cover 33 is equipped with several latches 36 for locking to the other side of the bottom cover 31. The bottom cover 31 and the top cover 33 form a closed space for accommodating circuit boards and related components.

[0038] refer to Figure 7 and Figure 8 The bottom cover 31 of the power supply box includes a bottom plate and a first sidewall 31b extending upward from the edge of the bottom plate. The outer surface of the bottom plate has an outwardly extending connecting seat 32, which is integrally formed with the bottom plate 31. A connector is provided inside the connecting seat 32 to connect with the display module 20. Preferably, an annular sealing ring is fitted around the outer periphery of the connecting seat 32 to strengthen its waterproof connection with the display module 20.

[0039] refer to Figures 7 to 9 The power supply box 30 is detachably mounted to the frame 10 via a connecting plate 39. The connecting plate 39 includes a first connecting portion 46 detachably connected to the power supply box 30 and a second connecting portion 48 detachably connected to the frame 10. The first connecting portion 46 is connected to an end of the power supply box 30, allowing operation from the rear of the frame 10, thereby allowing the power supply box 30 to be installed and removed from the rear of the frame 10. The second connecting portion 48 is connected to the front of the vertical beam 15, allowing operation from the front of the frame 10, thereby allowing the power supply box 30 to be installed and removed from the front of the frame 10. Understandably, if the second connecting portion 48 is connected to the rear of the vertical beam 15, the second connecting portion 48 can be operated from the rear of the frame 10; correspondingly, the first connecting portion 46 can be operated from the front of the frame 10.

[0040] In this embodiment, the first connecting part 46 and the second connecting part 48 form an L-shaped bend. The second connecting part 48 is detachably connected to the front of the frame 10, and the first connecting part 46 is detachably connected to the end of the power supply box 10.

[0041] Preferably, both the first connecting part 46 and the second connecting part 48 are sheet-like, and the connecting plate 39 is formed by bending the sheet material. The power supply box 30 is located between the two vertical beams 15. The second connecting part 48 is detachably connected to the two vertical beams 15 by screws, and the first connecting part 46 is detachably connected to the end of the power supply box 30 by screws.

[0042] refer to Figures 10 to 12In this embodiment, the disassembly / assembly structure 50 includes a fixing base 51, a connector 60, and an elastic element (not shown in the figure). The fixing base 51 is used to connect to a first component, such as the display module 20. The fixing base 51 includes a first through hole 55. The connector 60 includes a rod 61, a positioning element 63 connected to the rod 61, and a locking element 65. The rod 61 passes through the first through hole 55, and the positioning element 63 and the locking element 65 are located on both sides of the fixing base 51, respectively. The locking element 65 extends radially outward along the rod 61. In this embodiment, the locking element 65 extends radially outward to both sides of the rod 61.

[0043] The elastic element of the disassembly / assembly structure 50 is compressed between the connector 60 and the first component, such as the display module 20, so that the positioning member 63 abuts against the fixed base 51 and can be stabilized relative to the fixed base 51 in a first position and a second position respectively as the rod 61 rotates. The locking member 65 can disengage from the connecting portion 18 of the second component, such as the frame 10, when the positioning member 63 is in the first position, and is locked by the connecting portion 18 of the second component, such as the frame 10, when the positioning member 63 is in the second position. For example, as... Figure 4 As shown, the connecting hole 19 of the connecting part 18 is elliptical. Figure 4 In the indicated state, the locking member 65 can pass through the connecting hole 19 and disengage from the connecting part 18, thereby allowing the display module 20 to be removed. Figure 4 The state shown can be understood as the first position. Understandably, rod 61... Figure 4 When the device is rotated by a preset angle, such as 90 degrees, as shown, the locking member 65 will be unable to pass through the connecting hole 19 and will be locked by the connecting part 18, thereby locking the display module 20 to the frame 10. Understandably, the connecting part 18 and its connecting hole 19 may have other forms, as long as the locking member 65 can be disengaged in the first position and locked in the second position.

[0044] refer to Figures 10 to 12 The positioning member 63 is provided with a receiving groove 64 for receiving one end of the elastic member. That is, one end of the elastic member is received in the receiving groove 64, and the other end elastically abuts against the display module 20, so that the positioning member 63 of the rod 61 elastically abuts against the fixing seat 51.

[0045] At least a portion of the disassembly structure 50, such as the locking element 65, is exposed on the back of the frame 10, allowing the disassembly structure 50 to be operated from the back of the frame 10 to disassemble or assemble the display module 20. A clearance is provided on the front of the display module 20, allowing the rod 61 of the disassembly structure 50 to be operated from the front of the display module 20 to disassemble or assemble the display module 20.

[0046] Preferably, the end of the rod 61 near the first component (i.e., near the display module 20) is provided with a recess 67, which is non-circular. In this way, the display module 20 can be pre-configured with a through-hole extending through its thickness direction. This through-hole serves as a clearance, allowing the user to use a tool to insert through the through-hole into the aforementioned second through-hole or recess 67 from the front of the display module 20 to rotate the rod 61, facilitating installation or removal of the display module 20 from the front. Understandably, the user can also rotate the rod 61 from the back of the display module 20 using the locking member 65 to achieve installation or removal from the back of the display module 20. Furthermore, the recess 67 can be a through-hole extending through the length of the rod 61. In this case, a tool can also be inserted into the recess 67 from the back of the display module 20 to rotate the rod 61. In summary, through this disassembly and assembly structure 50, users can disassemble and assemble the display module 20 from both the front and back, making it convenient to install and maintain the display module 20.

[0047] refer to Figure 3 , Figure 11 and Figure 12 Considering that the front of the display module 20 is the display surface, there are usually no convenient gripping points for users to grasp and move the display module 20. In this embodiment, two or more threaded holes 22 are provided in the display module 20, which allows users to grasp and move the display module 20 by screwing in a screw from the front of the display module 20. Understandably, the threaded holes 22 can also be provided in the disassembly structure 50, for example, in the rod 61 and coaxial with the recessed hole 67. When the threaded holes 22 are provided in the rod 61 and coaxial with the recessed hole 67, one feasible solution is that the threaded holes 22 are located near the end of the recessed hole 67 close to the display module 20, and preferably the diameter of the threaded holes 22 is larger; another feasible solution is that the threaded holes 22 are located far from the end of the recessed hole 67 from the display module 20, and preferably the diameter of the threaded holes 22 is smaller.

[0048] In this embodiment, the positioning member 63 is a ring that is fixedly sleeved onto the rod body 61. The end face of the positioning member 63 near the fixing seat 51 engages with the fixing seat 51 through a concave-convex structure to stabilize it in the first position and the second position, respectively. Specifically, the end face of the positioning member 63 near the fixing seat 51 is provided with a plurality of positioning recesses 68, which are arranged circumferentially around the ring body. The fixing seat 51 is provided with corresponding positioning protrusions 58. In this embodiment, the positioning protrusions 58 are formed by bending a sheet material with a free end, thereby possessing a certain degree of elasticity.

[0049] In this embodiment, the fixing base 51 is provided with a first limiting part 56 at the first through hole 55, and the rod body 61 is provided with a second limiting part 62. The second limiting part 62 cooperates with the first limiting part 56 to define a first position and / or define a second position. (Reference) Figure 4 and Figure 6 Rod 61 from Figure 4 When the shown state (equivalent to the first position) is rotated 90 degrees counterclockwise, the second limiting part 62 will be limited by the first limiting part 58, and being limited is equivalent to the second position. Understandably, by reasonably setting the positional relationship between the second limiting part 62 and the first limiting part 56, the cooperation between the two can define the first position and / or the second position.

[0050] refer to Figures 11 to 14 In this embodiment, the fixing base 51 includes a first fixing base 52 and a second fixing base 53 stacked together. The first fixing base 52 is thicker, and the second fixing base 53 is thinner. The second fixing base 53 is sheet-shaped and includes a sheet material with a free end, which is bent to form a positioning protrusion 58.

[0051] Preferably, the interlocking structure between the positioning member 63 and the fixing seat 51 has different matching depths, so that the locking member 65 is closer to the fixing seat 51 in the second position than in the first position. Figure 2 In the second position, the locking member 65 is closer to the fixing base 51 than in the first position. In other words, the locking member 65 further presses against the connecting part 18 in the second position, thereby locking the connecting part 18 more stably. Conversely, in the first position, the locking member 65 is further away from the fixing base 51 than in the second position. In other words, the pressing of the locking member 65 on the connecting part 18 is relaxed, making it easier to disassemble the display module 20.

[0052] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
