Description

Key structure and input device Technical Field The present utility model relates to a key structure, and more particularly, to a key structure for an input device. Background In an electronic product such as a keyboard of a notebook computer, some keys have a function of lighting display to display characters on a key cap or as status indicator lamps. Such designs often place the light source outside of the key body or at the corner of the key cap to avoid structural interference of the key body with the light source. However, this makes the layout extremely limited, which is disadvantageous for key miniaturization. Disclosure of utility model The utility model provides a key structure, the structural layout of which is beneficial to miniaturization of products. The utility model relates to a key structure, which comprises a key cap, a bottom plate component, a light source and a scissor assembly. The keycap is provided with a light-transmitting area. The bottom plate subassembly is located the below of key cap. The light source is arranged on the bottom plate component. The scissors foot component is arranged between the keycap and the bottom board component and is suitable for moving along a first direction. The scissors foot assembly comprises a first supporting leg and a second supporting leg which are pivoted with each other, openings are respectively formed on the same sides of the first supporting leg and the second supporting leg, and the openings correspond to the light source and the light transmission area in the first direction. In an embodiment of the utility model, each of the first leg and the second leg includes a stand and a connecting portion, and the stand is connected between ends of the two legs via the connecting portion. The opening is formed in the stand. In an embodiment of the utility model, a horizontal position of the stand in the first direction is higher than a horizontal position of the connecting portion. In an embodiment of the utility model, the stand of the first leg has a receiving area at one side in a second direction, at least a portion of the stand of the second leg is located in the receiving area, and the second direction is perpendicular to the first direction. In an embodiment of the utility model, the stand of the first leg and the stand of the second leg at least partially overlap in the first direction. In an embodiment of the utility model, the opening is formed by recessing from one side of the stand along a second direction, and the second direction is perpendicular to the first direction. In an embodiment of the utility model, the openings of the first leg and the openings of the second leg face opposite directions. In an embodiment of the utility model, the openings of the first leg and the openings of the second leg face in the same direction. In an embodiment of the utility model, an opening of one of the first leg and the second leg is a through hole, and the through hole penetrates through the stand along the first direction. In an embodiment of the utility model, the key structure further includes a reinforcing portion disposed around the opening and extending in the first direction. In an embodiment of the utility model, the stand of one of the first leg and the second leg further includes a cylindrical portion extending along the edge of the opening in the first direction. In an embodiment of the utility model, a gap is formed between the stand and the light source. In an embodiment of the utility model, a gap is formed between the bottom surface of the scissor assembly and the bottom plate assembly. In an embodiment of the utility model, the chassis assembly includes a thin film circuit layer and a chassis main body. The thin film circuit layer is arranged on the bottom plate main body, and the light source is arranged on the thin film circuit layer. In an embodiment of the utility model, the chassis assembly includes a chassis main body and a backlight module. The backlight module is arranged below the bottom plate main body, and the light source is arranged on the backlight module. The input device comprises the key structure. Based on the above, in the key structure of the present utility model, the scissor assembly is disposed between the keycap and the base plate assembly and is adapted to move along the first direction. The first support leg and the second support leg of the scissors foot assembly are respectively provided with an opening at the same side, and the openings correspond to the light transmission areas of the light source and the keycaps arranged on the bottom plate assembly. By forming the openings in the scissor assemblies, light from the light source can pass through the openings well and radiate out of the keycap from the light transmitting area. Therefore, the light source can be arranged below the scissor assembly instead of being arranged at a position far away from the scissor assembly, so that the plane size can be furth
