[0042] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0043] like Figures 1 to 14As shown, according to the first aspect of the present application, the present application provides a display module 100, including a module bottom shell 101 and a light board 102 having a first mounting portion, and the module bottom shell 101 includes a bottom shell body 101a and a reinforcement structure 101b. Among them, the bottom shell body 101a has a first accommodating groove, and a first assembly part 1011a is arranged at the bottom of the first accommodating groove. The second assembly part 1011b and the second mounting part 1013b are arranged on the reinforcement structure 101b. The reinforcement structure 101b is fixed in the first accommodating groove by the cooperation between the first assembly part 1011a and the second assembly part 1011b, and the lamp board 102 is fixed on the second mounting part 1013b through the first mounting part. It is not only simple in structure and use, but also can enhance the strength of the bottom shell body 101a and support the lamp board 102. Moreover, by utilizing the separate design of the reinforcement structure 101b and the bottom shell body 101a, when one part of the reinforcement structure 101b and the bottom shell body 101a is damaged, the reinforcement structure 101b and the bottom shell body 101a can be repaired or replaced separately accordingly, without replacing the reinforcement structure 101b and the bottom shell body 101a at the same time, thereby reducing the maintenance cost.

[0044] It should be noted that the first assembly member 1011a and the second assembly member 1011b may be mutually matched snap-fit ​​structures, or may be other suitable structures for detachably fixing the reinforcement structure 101b in the first receiving groove, such as screws and studs.

[0045] In an optional embodiment, the first assembly part 1011a is a snap-fit ​​protrusion arranged on the bottom shell body 101a, and the second assembly part 1011b is a slot structure arranged on the reinforcement structure 101b. The snap-fit ​​protrusion and the slot structure are snap-fitted to fix the reinforcement structure 101b and the bottom shell body 101a together, and the snap-fit ​​connection has high reliability, ensuring that the reinforcement structure 101b is not easily separated from the bottom shell body 101a during the transportation or assembly of the display module 100, which not only facilitates disassembly and installation, but also reduces assembly costs and does not require any locking parts.

[0046] In an optional embodiment, the reinforcing structure 101b includes a first reinforcing rib and a second reinforcing rib arranged at intervals, and at least part of the structure of the first reinforcing rib and the second reinforcing rib extends along the length direction of the bottom shell body 101a to strengthen the strength of the slender bottom shell body 101a, and can also provide support for the lamp panel 102.

[0047] In an optional embodiment, the structure of the first reinforcing rib is the same as that of the second reinforcing rib, both of which include two vertical ribs 1012b extending in the length direction and a plurality of transverse ribs 1013b extending in the width direction, and the plurality of transverse ribs 1013b are connected between the two vertical ribs 1012b and arranged at intervals. Each module bottom shell 101 is vertically mounted with at least two lamp panels 102, and if the reinforcing structure 101b is made into a slender structure, it is easy to cause the reinforcing structure 101b to be damaged or broken during assembly or movement. Therefore, the present application uses the first reinforcing rib and the second reinforcing rib to be arranged side by side in the vertical direction on the bottom shell body 101a, and can also support the two lamp panels 102.

[0048] In an optional embodiment, the module bottom shell 101 also includes a matching structure 101c, which is connected to the side opposite to the first reinforcement rib and the second reinforcement rib and is fixedly connected to the bottom shell body 101a, which can not only strengthen the strength of the bottom shell body 101a, but also play a connecting role between the first reinforcement rib and the second reinforcement rib, and can support the light board 102.

[0049] In an optional embodiment, the mating structure 101c includes a snap-on base 1012c and a raised strip 1011c extending along the width direction of the bottom shell body.
