[0020] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0021] A safety glass cover plate of an arc-shaped convex platform type, refer to Figure 1, including a cover plate body 10, the cover plate body 10 includes a first glass cover plate 20 and a second glass cover plate 30 arranged in sequence from top to bottom, and the first glass cover plate 20 and the second glass cover plate 30 are adhesively fixed. The upper surface of the first glass cover plate 20 is arranged in an arc shape, the lower surface of the first glass cover plate 20 is arranged in a plane, the second glass cover plate 30 is arranged in a plane, and the lower surface of the first glass cover plate 20 is adhesively fixed to the second glass cover plate 30.

[0022] Referring to Figure 1 , the first glass cover plate 20 is provided with a certain thickness, the first glass cover plate 20 is tempered glass, the first glass cover plate 20 is presented in a semi-transparent black setting, and the upper surface of the first glass cover plate 20 is made of arc-shaped tempered glass with a wavelength of 550nm and a transmittance of about 40%.

[0023] Referring to Figure 1 , the cover plate body 10 is composed of a middle visible area 11 and an invisible area 12 arranged outside the visible area 11. The visible area 11 is used to display the picture, and the invisible area 12 is the border area of the cover plate body 10 and is not used to display the picture. The first glass cover plate 20 is presented in a semi-transparent black setting, so that the light transmittance of the middle visible area 11 of the first glass cover plate 20 is reduced, so that when the screen is not lit, the middle visible area 11 of the first glass cover plate 20 and the surrounding invisible area 12 present an integrated black effect.

[0024] Referring to Figure 1 , the second glass cover plate 30 is transparent colorless tempered glass, and the thickness of the second glass cover plate 30 is less than the thickness of the first glass cover plate 20. The size of the second glass cover plate 30 is larger than the size of the first glass cover plate 20, so that the first glass cover plate 20 and the second glass cover plate 30 form a cover plate body 10 with a convex platform shape. By combining the first glass cover plate 20 and the second glass cover plate 30 to form an arc-shaped convex platform-shaped cover plate body 10, the processing difficulty and cost are reduced, and the yield and efficiency of the cover plate body 10 are improved.

[0025] Further, referring to Figure 1 , the stepped surface of the second glass cover plate 30, that is, the area where the second glass cover plate 30 exceeds the first glass cover plate 20, is used to fit with the casing to achieve assembly and fixation.

[0026] Referring to Figure 1 , a black light-shielding ink 40 is provided on the lower surface of the second glass cover plate 30, and the black light-shielding ink 40 is screen-printed on the lower surface of the second glass cover plate 30. The black light-shielding ink 40 is arranged relative to the invisible area 12 of the cover plate body 10, and the black light-shielding ink 40 makes the invisible area 12 of the cover plate body 10 present black, so that when the screen is off, the middle visible area 11 and the surrounding invisible area 12 present an integrated black effect.

[0027] Referring toFigure 1 A bonding layer 50 for bonding and fixing is provided between the first glass cover plate 20 and the second glass cover plate 30. The size of the bonding layer 50 is adapted to the size of the first glass cover plate 20, and the bonding layer 50 bonds the first glass cover plate 20 and the second glass cover plate 30 together.

[0028] Further, referring to Figure 1 , the bonding layer 50 is PVB glue. PVB glue has better bonding force compared with ordinary optical glue. The hydrogen bond between the SiOH in the first glass cover plate 20 and the second glass cover plate 30 and the COH group in the PVB glue forms the bonding force, so that the glass will not fall off during the collision of the cover plate body 10.

[0029] Referring to Figure 1 , the arc-surface convex platform type cover plate body 10 is combined by setting the first glass cover plate 20 and the second glass cover plate 30. The upper surface of the first glass cover plate 20 is arranged in an arc-surface convex platform type, and the second glass cover plate 30 is arranged in a flat surface. The first glass cover plate 20 and the second glass cover plate 30 are combined to form the arc-surface convex platform type cover plate body 10, thereby reducing the processing difficulty and cost, and improving the yield and efficiency of the cover plate body 10.
