The first box body 501 has a cavity 501-1 for accommodating electronic components. The first box body 501 has a first opening 501-2 on one side facing the display screen 2. The first opening 501-2 communicates with the cavity 501-1. The power supply is installed and removed from the cavity 501-1 through the first opening 501-2. A second socket 501-7 is provided on the first box body 501 for signal connection with the integrated circuit board of the display screen. The second socket 501-7 is provided on the first opening 501-2. The second box body 502 is an L-shaped structure. The second box body 502 is installed and fixed on the side of the first opening 501-2 to form a rectangular structure with the first box body 501. The length and height of the first opening 501-2 set on the first box body 501 are both greater than the length and height of the power supply, which is convenient for disassembly and assembly of the power supply. At the same time, the first opening 501-2 is facing the direction of the display screen 2, which can provide a large operating space for assemblers, especially when facing a position where the edge of the carrier is installed on the wall. If the opening is facing away from the display screen 2, the second box body 502 cannot be directly disassembled to directly replace the power supply in the first box body 501.

[0021] A accommodating cavity 501-3 is provided below the first box body 501, and the accommodating cavity 501-3 runs through the front and rear ends of the first box body 501. During actual installation and use, the first box body is installed above the protective cover 4 of the display screen. The protective cover 4 is in the accommodating cavity 501-3, and the first box body 501 completely covers the end surface of the protective cover 4.

[0022] The second box body 502 includes a horizontal plate 502-1 and a vertical plate 502-2. The horizontal plate 502-1 is vertically fixed to one side below the vertical plate 502-2. The horizontal plate 502-1 is above the first box body 501. A slot 501-4 is provided on one side above the first box body 501. One side of the horizontal plate 502-1 is inserted into the slot 501-4. The vertical plate 502-2 covers the first opening 501-2 and the protective cover 4 and is fixed to the first box body 501 by screws. When assembling the first box body 501 and the second box body 502, it is only necessary to slide the horizontal plate 502-1 into the slot 501-4 and then use screws to fix the vertical plate 502-2 to the first box body 501.
