Example one

This embodiment provides a case, a display module, and a display device. Among them, the cabinet participates in forming a display module, and a plurality of display modules are spliced together into a display device. Therefore, in order to more clearly describe the technical features and beneficial effects of the cabinet in this embodiment, in this specific embodiment mode, the display module and the display device using the cabinet are used as an example for description.

Referring to FIG. 1, the display device provided in this embodiment includes a plurality of display modules 300, and the peripheral sides of the plurality of display modules 300 are spliced to each other to form a display surface.

Please refer to FIG. 2 and FIG. 3 in combination, wherein the display module 300 includes a cabinet 100 and a display board module 200 installed on the front mounting surface 110 of the cabinet 100, and a power supply and control installed on the rear mounting surface of the cabinet 100. Module (not shown). The display board module 200 includes a plurality of RBG light sources arranged in a matrix. The power supply and control module is connected to an external power source, and then supplies power to the display board 200 and provides control signals. In this embodiment, the display device is displayed in a flat shape as an example for description. In other embodiments, curved display or slant display may be used.

Referring to FIG. 4, after the display device provided in this embodiment is assembled, the display module 300 located in the middle position can be disassembled, thereby having the effect of being able to maintain front and rear. Wherein, how to disassemble the display module 300 located in the middle position is specifically the structural change of the cabinet. The details are as follows:

The cabinet 100 includes a front mounting surface 110 for mounting the display board module 200 and a peripheral side surface (not labeled) provided on a rear side of the front mounting surface 110 and surrounding the front mounting surface 110. In this embodiment, the box 100 is in the shape of a rectangular parallelepiped. Of course, in other embodiments, the box may also have other shapes, such as a round cake, an hourglass, or other shapes.

The peripheral side surface is uniformly provided with a first region (not labeled) and a second region (not labeled) along the circumferential direction. The first region and the second region may have obvious boundary lines. For example, the first region is an upper side surface and a left side surface, and the second region is a lower side surface and a right side surface, so that corners are obvious boundary lines. Of course, it may not have obvious boundaries. For example, the first region includes a part of the upper and lower sides and all the left sides, and the second region includes a part of the upper and lower sides and all the right sides. Alternatively, the first area is provided only on the left side, and the second area is provided only on the right side.

A plurality of first connection structures 160 are protruded in the first region; please refer to FIG. 5, FIG. 6 and FIG. 7 in combination. The rear side of the first connection structure 160 and the second connection structure 170 of the other box 100 Front side mating connection. The first connection structures 160 are all disposed in the first region.

A plurality of second connection structures 170 corresponding to the plurality of first connection structures 160 are protruded in the second region. Please refer to FIG. 8 and FIG. 9 in combination. The front side of each of the second connection structures 170 and The rear side of the corresponding first connection structure 160 is correspondingly provided; the front side of the second connection structure 170 is mated with the rear side of the first connection structure 160 of the other box 100. The second connection structures 170 are all disposed in the second area. In addition, the first connection structure 160 is provided correspondingly. The front side of the second connection structure 170 and the rear side of the first connection structure 160 are correspondingly arranged in this embodiment, which means that the aforementioned front side and rear side are coplanar, so as to achieve direct connection with each other; Or it is aligned and indirectly connected by adding spacers in the middle. Among them, the coplanar state is a state including tightly stitched seams, and a normal manufacturing and assembly state with gaps or errors of tens / hundreds of meters.

The first connection structure 160 and the second connection structure 170 may be a snap connection, a screw connection, or a pin connection. This can achieve the effect of detachable connection. During assembly, since the rear side surface of the first connection structure 160 is used as a mating surface, the first connection structure 160 cannot be moved backward when disassembled, but can be moved forward. The front side of the second connection structure 170 serves as a mating surface. Therefore, when the second connection structure 170 is disassembled, it cannot move forward, but can move to the rear. Further, since the first connection structure 160 and the second connection structure 170 are distributed in the first region and the second region of the box 100. Therefore, the center line between the first region and the second region can be used as the axis to rotate, as shown in FIG. 4.
