Problems solved by technology

However, in the existing mechanical key structure 2, a circuit board 24 thicker than the membrane switch circuit 14 must be provided so that the mechanical trigger switch 23 can operate.
In addition, the thickness of the mechanical trigger switch 23 is also greater than the thickness of the elastic rubber body 13, so the thickness of the existing mechanical key structure 2 will be greater than the thickness of the existing key structure 1
In addition, since the interior of the mechanical trigger switch 23 contains metal materials and plastic materials, when the button cap 21 is pressed, the metal materials and plastic materials inside collide, so that the existing mechanical button structure 2 will give the user a stiff feeling. touch feel

Abstract

The invention relates to a button structure which comprises the components of a connecting board, a button cap which is provided with an extension part, a triggering element, a scissors type connecting component, a thin-film switching circuit and a supporting board. Furthermore the supporting board comprises an accommodating part and an elastic sheet structure. The elastic sheet structure corresponds with the extension part and is arranged in the accommodating part. When the button cap is pressed, the scissors type connecting component acts and moves the button cap for abutting against the triggering element, and furthermore the triggering element triggers the thin-film switching circuit. On the other hand, the extension part impacts the elastic sheet structure along with movement of the button cap, thereby generating sound.

Description

technical field [0001] The present invention relates to a button structure, in particular to a button structure utilizing scissor-type connecting elements. Background technique [0002] Common computer peripheral input devices include a mouse, a keyboard, and a trackball. The keyboard can directly input text and symbols to the computer, so it is 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 architecture of the key structure in the keyboard including the scissor-type connection elements is described. see figure 1 , which is a schematic cross-sectional side view of an existing button structure. 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 second key cap 11, the scissors-type conn...
