[0033] In this embodiment, by setting a first flame-retardant plate 2 on the inner side of the door opening 1, the wall panel has a hinge connection point with the hidden door 3, which can avoid the problem of wall panel structural damage caused by hinge between the wall panel and the hidden door 3. At the same time, setting the first flame-retardant plate 2 in the door opening 1 can also play a safety prevention role and avoid safety accidents such as fire.

[0034] Specifically, the hinge structure can be a hinge, a top and bottom hinge, or a hinge chain, etc., and these structures and distribution methods are all within the protection scope of this embodiment.

[0035] like Figures 1 to 4 As shown, in some embodiments, the side of the first flame-retardant board 2 is covered with a decorative panel 4, and the decorative panel 4 and the outer end face of the hidden door 3 are on the same plane.

[0036] In this embodiment, the hidden door 3 is an inward-opening door. The outer side of the first flame-retardant board 2 is covered with a decorative panel 4, and the outer side of the wall panel is also covered with a decorative panel 4. The decorative panel 4 of the first flame-retardant board 2, the decorative panel 4 of the wall panel, and the inward-facing side of the hidden door 3 are on the same plane, which effectively improves the flatness of the wall surface. The decorative panel 4 can cover the first flame-retardant board 2, improving the aesthetics and achieving a better invisibility effect.

[0037] like Figures 1 to 4 As shown, in some embodiments, a finishing strip 5 is provided in the gap between the face panel 4 and the hidden door 3.
