Problems solved by technology
However, the first elastic piece 25 and the second elastic piece 26 in the existing mechanical key structure 2 must pass through the base 21 to be connected to the circuit board, otherwise the operation of the mechanical key structure 2 will not be able to generate key signals.
However, there are a plurality of mechanical key structures 2 in the keyboard, and the first elastic piece 25 and the second elastic piece 26 in each mechanical key structure 2 must be electrically connected to the circuit board in sequence during the assembly process of the keyboard. Not only time-consuming and labor-intensive, thus increasing the cost of assembly

The present invention relates to a keyboard. The keyboard comprises a bottom plate, a pressure sensing layer, a first key structure and a second key structure, wherein the pressure sensing layer is provided with a plurality of pressure sensing areas, the first key structure and the second key structure are corresponding to one pressure sensing area separately and are located above the corresponding pressure sensing areas, the first key structure and the second key structure abut against the corresponding pressure sensing areas in response to different contact pressure, so that the pressure sensing areas can generate different pressure sensing signals. According to the keyboard of the present invention, the pressure sensing layers are adopted to replace a plurality of pressure sensing elements, so that the assembly process of the keyboard can be simplified, and the assembly costs of the keyboard can be reduced.
Description
technical field [0001] The present invention relates to a keyboard, in particular to a keyboard using a mechanical key structure. Background technique [0002] Common computer peripheral input devices include mice, keyboards, and trackballs. Among them, keyboards can directly input text and symbols to the computer, so they are highly valued by users and input device manufacturers. Among them, the more common one is a keyboard that includes a scissor-type connecting element. [0003] Next, the structure of the key structure in the keyboard is described, and the key structure includes scissor-type connecting elements therein. see figure 1 , which is a schematic cross-sectional side view of a key structure of an existing keyboard. The existing button structure 1 includes a button cap 11, a scissors-type connecting element 12, an elastic rubber body 13, a membrane switch circuit 14 and a bottom plate 15, and the bottom plate 15 is used to carry the key cap 11, the scissors-ty...
