As shown in FIGS. 1-2 and 4, a display board 1 mounting structure includes a first buckling portion 11 provided on the display board 1, a first limiting portion 12, and a second buckling portion provided on the substrate 2. Portion 21, the first buckling portion 11 is buckled with the second buckling portion 21, the first limiting portion 12 and the second buckling portion 21 are close to the side of the display panel 1 Abutting, that is, using the right ends of the first limiting portion 12 and the second buckling portion 21 to abut each other to achieve the limiting, wherein the first buckling portion 11 is opposite to the side of the display panel 1 away from each other. It is closer to the display panel 1 than the side of the second buckling portion 21 away from the display panel 1, that is, the left end of the first buckling portion 11 does not reach the left end of the second limiting portion.

This structure is adopted to realize the installation of the display board 1, and the first limit is used to limit the position. Since the triangular rib 22 is arranged at the right end of the boss, the first buckling portion 11 will not contact the triangular rib 22, as shown in FIG. 3 As shown, there is a certain distance between the end of the first buckling portion 11 and the triangular rib 22, and the distance is at least 2 mm. Through this kind of arrangement, the quality and life of the first buckling part 11 are ensured. In addition, the installation is carried out by floating up and down, which is convenient and fast for assembly and disassembly, and does not need to increase labor costs.

Among them, the base plate 2 may be a middle frame, a wiring cover, or an electric control box cover. In this embodiment, it is an electric control box cover.

Specifically, the first buckle 11 may be an elastic buckle, or a hook or a nail, etc., and may be an elastic buckle. If it is an elastic buckle, at least one pair must be provided, and the elastic The opening formed by the buckle faces the substrate 2.
