Further, the second sheet 2 is a rayon sheet of pre-impregnated resin, the functional layer includes at least two rayon sheets, and the thickness of each second sheet is 0.1-0.3mm. As described in the background section, the rayon sheet is thinner, so that the mounting holes 20 are formed by stacking two or more layers of the rayon sheet, so that a depth corresponding to the thickness of the magnetic attraction member 4 can be obtained, and thus, the surface of the functional layer can be flattened, and the phenomenon that an imprint is left on the decorative layer due to the height difference between the second sheet 2 and the magnetic attraction member 4 in the later hot pressing process is avoided.
Specifically, the type of the second sheet 2 and the thickness of the second sheet 2 are selected according to the thickness of the magnetic attraction piece 4, for example, the thickness of the magnetic attraction piece is 0.35mm, and the magnetic attraction piece (1) can be formed by stacking and pressing a glass fiber sheet material of which the second sheet 2 is a layer of pre-impregnated resin and an aramid fiber sheet material of which the thickness is 0.35+/-0.2 mm; at this time, a through hole can be directly formed as the mounting hole 20, and the depth of the mounting hole 20 is matched with the thickness of the magnetic attraction piece 4; (2) The second sheet 2 can also be formed by stacking and pressing four layers of glass fiber sheets of pre-impregnated resin, the thickness is 0.4+/-0.2 mm, a blind hole with the thickness of 0.35mm can be formed as the mounting hole 20, and the depth of the mounting hole 20 is matched with the thickness of the magnetic attraction piece 4.

In a first aspect, the first sheet 1 of one layer is thinner and thinner, and then the side frame 6 is weaker, so that, to improve structural strength and firmness during assembly, one layer of the second sheet of the functional layer and/or the second film 3 may be extended to the edge of the side frame 6, preferably, the thickness of the back plate 5 is 0.2-0.4mm, and the thickness of the second film 3 is 0.1-0.28mm, thereby enhancing the overall structural strength.
In the second scheme, when the decorative layer is the first sheet material 1 with at least two layers, the edges of the functional layer and the protective layer are all flush with the edges. The second consideration is that the at least two first sheet 1 can improve the structural strength of the side frame 6 and the firmness at the time of assembly, and the second sheet 2 or the second coating 3 does not need to be extended to the side frame 6. Preferably, the first sheet has a thickness of 0.1-0.25mm and can be composed of two different types of first sheets 1 of different thickness, so as to balance the relationship between the thickness of the decorative layer and the structural strength.
