[0034] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5As shown, the present application provides an LED display box, and some embodiments of the LED display box of the present application include: a support frame assembly 10, a connecting rib 80, and a flexible light board 40; the support frame assembly 10 includes a first vertical support frame 11, a second vertical support frame 12 adjacent to the first vertical support frame 11, a first connecting member 13 arranged on the first vertical support frame 11, and a second connecting member 14 arranged on the second vertical support frame 12, the first connecting member 13 and the second connecting member 14 are slidably and rotatably connected to adjust the angle between the first vertical support frame 11 and the second vertical support frame 12; the connecting rib 80 is connected to the front side of the support frame assembly 10, and the connecting rib 80 is a flexible structure, and the connecting rib 80 deforms as the angle between the first vertical support frame 11 and the second vertical support frame 12 changes; the flexible light board 40 is arranged on the front side of the support frame assembly 10 and is fitted and connected to the connecting rib 80.

[0036] Applying the technical solution of this embodiment, the support frame assembly 10 is the base of the LED display box, providing an installation foundation for other components of the LED display box; the flexible light board 40 is arranged on the front side of the support frame assembly 10 to realize the display function, the support frame assembly 10 includes a first vertical support frame 11, a second vertical support frame 12 and a first connecting member 13 and a second connecting member 14 arranged between the first vertical support frame 11 and the second vertical support frame 12. Since the first connecting member 13 and the second connecting member 14 are slidably and rotatably connected, the angle between the first vertical support frame 11 and the second vertical support frame 12 can be adjusted, and the connecting rib 80 is connected to the front side of the support frame assembly 10, and the connecting rib 80 deforms as the angle between the first vertical support frame 11 and the second vertical support frame 12 changes; the flexible light board 40 is arranged on the front side of the support frame assembly 10 and is fitted and connected to the connecting rib 80. In this arrangement, since the connecting rib 80 is a flexible structure, when the installation surface of the LED display box is a curved surface, after the LED display box is installed on the installation surface, the angle between the first vertical support frame 11 and the second vertical support frame 12 changes with the installation surface, so that the connecting rib 80 is deformed by the traction force of the support frame assembly 10, so that the shape of the connecting rib 80 matches the installation surface, and then the shape of the flexible light board 40 matches the installation surface. Compared with the solution of using straight screen splicing in the related art, this embodiment can make the flexible light board 40 present a continuous curved surface without creases, avoiding the influence of creases on the display effect, and ensuring the display effect and user experience of the LED display box. Therefore, the technical solution of this embodiment can effectively solve the problem of poor display effect of LED display boxes in the related art.

[0037] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 as well as Figure 10 As shown, one of the first connecting member 13 and the second connecting member 14 includes a first sliding groove 141, and the other of the first connecting member 13 and the second connecting member 14 includes a first sliding shaft 131 slidably inserted in the first sliding groove 141. Specifically, by providing the first sliding groove 141 and the first sliding shaft 131 slidably inserted in the first sliding groove 141, the first connecting member 13 and the second connecting member 14 can be relatively simply connected in a sliding and rotating manner, which has the advantage of easy processing.

[0038] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 as well as Figure 10 As shown, the first vertical support frame 11 includes a first frame body 111 and a first connecting block 112, the second vertical support frame 12 includes a second frame body 121 and a second connecting block 122, a first sliding shaft 131 is provided on the first connecting block 112, and the second connecting member 14 also includes an extension plate 142 provided on the second connecting block 122, a first sliding groove 141 is provided on the extension plate 142, and the end of the first sliding shaft 131 is inserted into the first sliding groove 141. Specifically, the first frame body 111 and the second vertical support frame 12 mainly play the role of support and installation. The first connecting block 112 and the second connecting block 122 extend in the transverse direction and are mainly used to set the connecting member. There are two extension plates 142 and are arranged opposite to each other. The first connecting block 112 is inserted between the two extension plates 142. Both extension plates 142 are provided with a first sliding groove 141. Both ends of the first sliding shaft 131 are inserted into the first sliding groove 141. Such an arrangement can ensure the stable connection between the first connecting member 13 and the second connecting member 14.

[0039] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 as well as Figure 10 As shown, the first connecting member 13 further includes a first stopper 132, which is disposed at the end of the first sliding shaft 131 and engages with the extension plate 142 for stopping. The first connecting member 13 further includes a second stopper 133, which is disposed on the first sliding shaft 131 and located between the extension plate 142 and the first connecting block 112. The first stopper 132 is provided to prevent the first sliding shaft 131 from falling out of the first sliding groove 141, while the second stopper 133 is used to reduce friction and prevent the first sliding shaft 131 from jumping in the vertical direction.

[0040] Furthermore, in this embodiment, a through hole is provided on the first connecting block 112, and the middle portion of the first sliding shaft 131 is rotatably disposed within the through hole. This arrangement allows the first connecting block 112 and the first sliding shaft 131 to rotate, which not only increases the flexibility of the LED display cabinet but also facilitates the installation of the first sliding shaft 131 and the first connecting block 112.

[0041] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 As shown, a weight-reducing groove 1121 is provided on the first connection block 112. Specifically, since the first connection block 112 has a certain thickness, multiple weight-reducing grooves 1121 are provided, thereby effectively reducing the weight of the first connection block 112, thereby reducing the overall weight of the LED display box.

[0042] like Figure 1 as well as Figure 2 As shown, a hook portion 61 is provided on the rear side of the first vertical support frame 11, and the hook portion 61 can be hung on the back frame. Specifically, there are multiple hook portions 61 and they are spaced apart in the horizontal direction. The provision of the hook portions 61 allows workers to quickly and easily connect the LED display box to the back frame, and multiple hook portions 61 can ensure a stable connection with the back frame.

[0043] like Figure 1 as well as Figure 2 As shown, the support frame assembly 10 also includes a connecting frame structure 62, the first connecting member 13 and the second connecting member 14 are both arranged in a plurality and in a one-to-one correspondence, the first connecting member 13 and the second connecting member 14 are respectively arranged at intervals along the vertical direction, and the two ends of the connecting frame structure 62 are respectively connected between two adjacent first connecting members 13 or between two adjacent second connecting members 14, and the LED display box also includes a power box 20, which extends in the transverse direction and is connected to the connecting frame structure 62. Specifically, in this embodiment, the back frame extends in the transverse direction, and the multiple back frames are spaced apart in the vertical direction and have an avoidance interval. The power box 20 extends in the transverse direction and can be arranged in the avoidance interval to have a better layout. The connecting frame structure 62 ensures the connection strength between the power box 20 and the support frame assembly 10.

[0044] like Figure 1 as well as Figure 2As shown, the first vertical support frame 11 and the second vertical support frame 12 both have an avoidance recess 63. The power box 20 is disposed between two adjacent first connecting members 13 or connected between two adjacent second connecting members 14, and the power box 20 is located in the avoidance recess 63. Specifically, the provision of the avoidance recess 63 ensures that neither the first vertical support frame 11 nor the second vertical support frame 12 interferes with the power box 20, thereby ensuring structural strength while also avoiding the power box 20, which is beneficial to the layout of the power box 20.

[0045] like Figure 2 as well as Figure 3 As shown, the power box 20 is detachably connected to the connecting frame structure 62. This arrangement can facilitate the staff to load and unload the power box 20, thereby facilitating the staff to inspect and maintain the power box 20. More specifically, the clamping head 66 is arranged on the front side of the power box 20, and the connecting frame structure 62 is provided with a mounting groove, which includes a connected avoidance groove section 64 and a clamping groove section 65. The avoidance groove section 64 is located above the clamping groove section 65, and the size of the avoidance groove section 64 is larger than the size of the clamping groove section 65. When the clamping head 66 is arranged corresponding to the avoidance groove section 64, the clamping head 66 can pass through the avoidance groove section 64. When the clamping head 66 is arranged corresponding to the clamping groove section 65, the clamping head 66 and the clamping groove section 65 are prevented from retreating. When installing the power box 20, the clamping head 66 is moved from the rear side of the avoidance groove section 64 through the avoidance groove section 64 to the front side of the avoidance groove section 64. Then, the clamping head 66 is moved to the engaging groove section 65 under the action of the gravity of the power box 20. The clamping head 66 abuts and cooperates with the plate structure of the engaging groove section 65 to achieve a retaining engagement between the clamping head 66 and the engaging groove section 65. To remove the power box 20, the operation is reversed. The power box 20 is electrically connected to the flexible light board 40 via a connecting wire.

[0046] like Figure 2 As shown, the lower end of the first vertical support frame 11 is provided with a swingable buckle 67, and the upper end of the first vertical support frame 11 is provided with a latch 68, and the buckle 67 can be engaged with the latch 68. Specifically, the buckle 67 and the latch 68 are provided to ensure that two adjacent LED display boxes above and below are stably connected when multiple LED display boxes are stacked. The swingable buckle 67 facilitates operation by the operator, thereby facilitating the connection or separation of adjacent LED display boxes.

[0047] In addition, the present application also includes other embodiments of the LED display box, and the other embodiments have the following features:

[0048] The power box 20 is arranged on the rear side of the support frame assembly 10, and the connection structure is arranged between the support frame assembly 10 and the power box 20. The connection structure includes a third connection member 31 and a fourth connection member 32. Since the third connection member 31 and the fourth connection member 32 are connected in a sliding and rotating manner, when the angle between the first vertical support frame 11 and the second vertical support frame 12 changes, the third connection member 31 and the fourth connection member 32 can also move synchronously, so that the power box 20 will not hinder the shape change of the support frame assembly 10. It should be noted that "the third connection member 31 and the fourth connection member 32 are connected in a sliding and rotating manner so that the angle between the first vertical support frame 11 and the second vertical support frame 12 can change" means that when the angle between the first vertical support frame 11 and the second vertical support frame 12 changes, the power box 20 will not hinder the shape change of the support frame assembly 10.

[0049] like Figures 4 to 9 As shown, the power box 20 is arranged in the horizontal direction, the fourth connecting member 32 includes an extension plate 321 arranged at the end of the power box 20 and a second slide groove 322 arranged on the extension plate 321, and the third connecting member 31 includes a mounting bracket 311, one end of the mounting bracket 311 is connected to the support frame assembly 10, and the other end of the mounting bracket 311 is provided with a protrusion that is slidably inserted into the second slide groove 322. Specifically, the cooperation between the second slide groove 322 and the protrusion can relatively easily realize the sliding and rotational connection between the third connecting member 31 and the fourth connecting member 32, which has the advantages of simple structure and easy processing. In addition, it should be noted that "the second slide groove 322 arranged on the extension plate 321" refers to: the second slide groove 322 is entirely arranged on the extension plate 321 or most of it is arranged on the extension plate 321 (part of it may be arranged on the power box 20 to control the overall size of the power box 20 and the fourth connecting member 32).

[0050] like Figures 4 to 9 As shown, both the first slide groove 141 and the second slide groove 322 are arcuate grooves. The provision of the arcuate grooves can make the angle change between the first vertical support frame 11 and the second vertical support frame 12, as well as the relative position change between the support frame assembly 10 and the power box 20, smoother, avoiding the possibility of jamming. In this embodiment, the support frame assembly 10 can be in a forward protruding state or a backward protruding state.

[0051] like Figures 4 to 9As shown, the first vertical support frame 11 and the second vertical support frame 12 are both multiple and alternately arranged in the transverse direction. The mounting bracket 311 is connected to the outer first vertical support frame 11 or the second vertical support frame 12. The LED display box further includes a fixing bracket 50, which is connected between the power box 20 and the inner first vertical support frame 11 or the second vertical support frame 12. Specifically, with such an arrangement, no matter how the shape of the support frame assembly 10 changes, the relative position between the inner vertical support frame and the power box 20 does not change, but the movement of the outer vertical support frame drives the mounting bracket 311 to move.

[0052] like Figures 4 to 9 As shown, the power supply box 20 includes a box body 21 and a box cover 22 rotatably arranged on the box body 21. A first magnetic member is provided on the box body 21, and a second magnetic member that magnetically cooperates with the first magnetic member is provided on the box cover 22. Specifically, a plurality of electrical components such as a control card and a power supply are provided in the box body 21. The box cover 22 is used to protect the electrical components in the box body 21. The box cover 22 is rotatably arranged so that the staff can more conveniently maintain the electrical components. The first magnetic member and the second magnetic member can achieve a stable connection between the box body 21 and the box cover 22. The electrical components in the box body 21 are electrically and signally connected to the flexible light board 40 through electrical connectors such as wires. The flexible light board 40 is also connected to the support frame assembly 10 by magnetic attraction. The support frame assembly 10 is also connected to the mounting surface such as the back frame by magnetic attraction.

[0053] like Figure 9As shown, the box body 21 is provided with a second slide shaft 211 located on the inner side of the extension plate 321, and the box cover 22 is provided with a third slide groove 221. The second slide shaft 211 is slidably inserted into the third slide groove 221. The first end of the third slide groove 221 is arranged near the edge of the box cover 22 relative to the second end of the third slide groove 221. When the box cover 22 is in the closed state, the second slide shaft 211 is located at the second end of the third slide groove 221. When the box cover 22 is in the open state, the second slide shaft 211 is located at the first end of the third slide groove 221. Specifically, compared to arranging the rotating shaft horizontally, the vertical arrangement of the second slide shaft 211 prevents the box cover 22 from being placed on the box body 21 simply due to the action of gravity. Since the extension plate 321 is arranged on the outside, in order to avoid interference with the extension plate 321, the second sliding shaft 211 is arranged on the inner side of the extension plate 321. If the hinge-like structure in the related art is used, the lateral size of the box cover 22 will be smaller, and it will not be possible to completely cover the opening of the box body 21; through the above arrangement, when the box cover 22 switches from the closed state to the open state, the second sliding shaft 211 is moved from the second end of the third sliding groove 221 to the second end. At this time, when the box cover 22 is rotated, the box cover 22 will not interfere with the box body 21, thereby not limiting the size of the box cover 22 and not hindering the opening and closing of the box cover 22.

[0054] The present application also provides an LED display device, comprising an LED display housing, wherein the LED display housing is the aforementioned LED display housing. The aforementioned LED display housing can effectively resolve the problem of poor display effects of LED display housings in related arts, and the LED display device having the aforementioned LED display housing also has the aforementioned advantages.
