Description

Button structure and its keyboard

technical field

The utility model relates to a button, in particular to a button structure capable of increasing the pressing stroke and a keyboard thereof.

Background technique

As shown in FIG. 1 , an existing button 1a applied to a keyboard generally includes a substrate 10a, a keycap 11a, and a connecting component 12a movably connected between the substrate 10a and the keycap 11a, and the connecting component 12a An elastic member 120a is provided inside to pass through, and is abutted against the inside of the keycap 11a and the substrate 10a, and a circuit layer 100a is provided on the substrate 10a, and a conductive protrusion is protruded from the circuit layer 100a corresponding to the elastic member 120a. Membrane 101a. When the keycap 11a is pressed by the human hand, the connecting component 12a can drive the keycap 11a to move downward to press the elastic member 120a, and make the elastic member 120a touch the conductive membrane 101a, so as to achieve the effect of typing on the keyboard. The purpose of signal input such as button 1a.

However, as shown in FIG. 2 , when the general user types the keyboard quickly, there may be a deviation in the position of the pressed key cap 11a, such as the commonly known "multiple keys" such as the blank key, Shift key, and Enter key on the general keyboard. ", because the width of the keycap itself is wider than the width of the general "double key", so when the pressing is unbalanced, it is easy to cause the keycap 11a to move incompletely in the downward displacement, so that it is impossible to adjust the keycap 11a. 11a provides a relatively complete pressing stroke, so the elastic member 120a is not completely pressed by the keycap 11a, so it is impossible to ensure that the elastic member 120a is in contact with the conductive membrane 101a. The function of providing signal input, and the edge of the keycap 11a will easily generate noise due to the impact on the bottom surface. In order to avoid or reduce the occurrence of this problem, one of the factors that may affect it is sought: if the pressing stroke provided when pressing the keycap 11a can be increased (that is, to strive for the distance h in Figure 2), the key can be further made The cap 11a presses the elastic member 120a more reliably, thereby ensuring that the elastic member 120a can effectively touch the conductive membrane 101a, so as to achieve the purpose of signal input.
