According to the embodiment, the cantilever type buckle is arranged between the key cap and the key shell, so that the edge of the key cap is consistent in hand feeling, and the comfort level of a product is improved. For specific reasons, referring to fig. 5, a circle formed by the fulcrums of the four cantilever beam buckling positions is taken as a fulcrum, the corresponding fulcrum is taken as a when a single buckling point C is pressed, the movement direction of the cantilever subjected to micro deformation under the pressing is AC, and the direction of the BD force is perpendicular to the movement direction. When the position of the point E is pressed, the angles of CE and AE are combined into AC and BE and ED are combined into BD according to the pythagorean theorem because AC and BD are both diameters of a circle, and the angle cea= angle bed=90° (the angle formed when the point E is not overlapped with the points a, B, C and D) is combined by the plane force system force according to the parallelogram law. Since E is located at any point on the circle, it can always be synthesized as AC and BD. I.e. point E is as stressed as point C.
Thus, the feel between the two snaps is the same.
Based on the same technical concept, in other embodiments, an electronic device is provided, including the above-mentioned key device.
The foregoing describes specific embodiments of the present utility model. It is to be understood that the utility model is not limited to the particular embodiments described above, and that various changes and modifications may be made by one skilled in the art within the scope of the claims without affecting the spirit of the utility model.
