Light leakage prevention structure of keyboard plate and intelligent switch panel

The utility model relates to a light leakage prevention structure of a key board and an intelligent switch panel, the light leakage prevention structure comprises a PCB, a key support and at least two key boards, the key boards are movably connected above the key support, and the key support is connected above the PCB; the splicing sides of the key boards are provided with convex edges or lap joints, and the convex edges and the lap joints of every two adjacent key boards are matched with each other. And the splicing side refers to one side, close to the adjacent key board, of one key board. According to the utility model, the convex edges or the lapping ports are arranged on the splicing sides of the key boards, and a corner structure is formed at the splicing part of the two key boards through the matching of the convex edges and the lapping ports, so that the effect of continuously weakening light propagation is achieved through the diffuse reflection of light rays through a host, and the problem of light
