Problems solved by technology

However, in the process of pursuing volume reduction, the thickness of some or all components in the button structure must be thinner, which instead causes the structural strength of the button structure to weaken and be easily damaged, and also causes the button structure to have a poor touch feeling.

Abstract

The invention relates to a button structure, comprises a base plate, a button cap, a first vertical connecting rod, a second vertical connecting rod, a first transverse connecting rod and a second transverse connecting rod. The button cap is positioned above the base plate and can move relative to the base plate. The first vertical connecting rod, the second vertical connecting rod, the first transverse connecting rod and the second transverse connecting rod are connected with the button cap and the base plate respectively, and are located at the first side, the second side, the third side and the fourth side of the button cap. The first end of the first transverse connecting rod is overlapped with the first vertical connecting rod, and the second end of the first transverse connecting rod is overlapped with the second vertical connecting rod. The first end of the second transverse connecting rod is overlapped with the first vertical connecting rod, and the second end of the second transverse connecting rod is overlapped with the second vertical connecting rod. The plurality of connecting rods are evenly distributed in the range of the button cap, so as to enable the button cap to stably move relative to the base plate. As the thicknesses of the connecting rods are smaller than that of the traditional scissor-type connecting elements, the thickness of the button cap can be reduced.

Description

technical field [0001] The present invention relates to a key structure, in particular to a key structure that does not use scissor-type connecting elements. 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 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-...
