Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic floor tiles, and in particular to a photovoltaic floor tile. Background Art

[0002] Solar luminous floor tiles, also known as photovoltaic floor tiles, are mainly composed of a shell, a light-emitting panel, a light-emitting body, a solar circuit board and a battery. Solar luminous floor tiles use single crystals and polycrystalline as power sources, and the light-emitting panel is a panel made of a light-transmitting material, which has at least one semi-transparent scattering layer. The structure is simple and has better lighting and decorative effects. If the photovoltaic floor tiles generate a large amount of electricity, the excess electricity can also be supplied to the outside.

[0003] The upper end surface of existing photovoltaic floor tiles is made of hard transparent material, generally tempered glass, and is designed to be non-detachable. Since the surface of photovoltaic floor tiles is relatively smooth, it is not conducive to full paving of the road surface, the solar energy collection surface is small, and there is a risk of slipping. Moreover, after a long period of laying, the surface of photovoltaic floor tiles will inevitably wear out, reducing the light transmittance, and the non-detachable method cannot solve this problem well.

The plurality of convex strips are provided on the upper end surface of the upper cover plate to play an anti-slip role, and the cross section of the convex strip is an isosceles trapezoid, and the angle between its waist and the bottom edge is less than ninety degrees, which is more conducive to cleaning along the length direction of the convex strip, because the cleaning tools, such as the bristles on the brush, are more likely to extend into the angle between the convex strip and the surface of the upper cover plate and clean it. In addition, the upper cover is made of thermoplastic transparent plastic. The purpose of the transparent material is to allow light to enter the interior to provide power generation, and the purpose of the thermoplastic material is that if the upper cover is scratched during long-term use, it will lead to reduced light transmittance and reduced power generation.
