In view of this, the utility model applicant this in the experience of being engaged in computer keyboard research and development and production and marketing for many years, the phase can be improved many disappearances of prior art, and do not lose due comfortableness, concentrate on studies,, and then develop and " keycap structure " of the present utility model through experiment and test repeatedly.

The utility model content

The purpose of this utility model provides a kind of keycap structure, to overcome the defective of not having a comfortableness of prior art.

The utility model comprises:

One key shell is the hard material housing, and at least one edge of its end face and abuts with wall junction, below form a shell groove;

One soft elastic edgings, it is to fill up in this shell groove to form, so that increase the comfortableness when operating.

The utility model secondary objective is to provide a kind of keycap structure, and wherein this key shell is an ejection formation, elastic edgings then via the second time ejection formation in the shell groove.Moreover, wherein have most reinforced ribs/sheets in this shell groove.In addition, this key shell and elastic edgings are to be same color.

Another purpose of the utility model is to provide a kind of keycap structure, and wherein these key shell central authorities form a shell hole, and a soft elasticity is connect face fills up the person of forming in this shell hole in addition.Moreover, have at least one reinforced ribs/sheet in this shell hole.In addition, to connect face be to be same color for this key shell and elasticity.

Via enforcement of the present utility model, it can replace with an elastic edgings at least one edge of keycap end face and the formed sharp-pointed portion in junction of abuts with wall, people are pointed in the process of pushing key entry, when touching this elastic edgings, do not have outside the sense of discomfort, and meet the operation of ergonomics.Particularly, the utility model keycap central authorities also must be provided with an elasticity and connect face, and preferable haptic effect is provided, even if permanent operation also can be delayed and be closed the sclerosis of the skin that refers to abdomen or the situation of elongated cocoon takes place, really are a ware big good structure not seen before.
