Embodiment Construction

[0071] see Figure 1 to Figure 5 . A key structure 1 according to an embodiment of the present invention includes a base 10 , a keycap 12 , a restoring force mechanism 14 , a light source device 16 and a switch 18 . The keycap 12 is arranged on the base 10, and the restoring force mechanism 14 is arranged between the base 10 and the keycap 12; through the sliding combination between the base 10 and the keycap 12, the keycap 12 can be parallel to the direction D1 (with Arrow indicates at Figure 4 and Figure 5 middle) to selectively move toward or away from the base 10. Among them Figure 4 or Figure 5 In terms of viewing angle, the direction D1 is equivalent to the vertical direction. In this embodiment, the restoring force mechanism 14 is a combination of springs, which includes a first spring 142 and a second spring 144, the first spring 142 and the second spring 144 are connected in series and arranged between the base 10 and the keycap 12, wherein The upper end of...

Abstract

The invention discloses a key structure, providing resilience for a keycap by using a spring set composed of a plurality of springs in serial connection; when the keycap moves toward a base of the key structure and after the keycap exceeds a shift position, one spring stops continuously deforming; therefore, elasticity coefficient of the whole spring set increases, and elastic energy storage of the spring set can be increased; as a result, when a user presses the keycap, feedback force light and then great may be perceived; the feedback force is characteristically helpful for the user to press the keycap quickly, and the keycap may return quickly after being pressed; furthermore, the key structure may employ a lateral-acting switch, and the influence of resilience of the switch upon vertical movement of the keycap; the key structure may also employ a spring plate arranged below a keycap, and tactile feedback may be provided for a user to a the switch.

Description

technical field [0001] The present invention relates to a button structure, in particular to a button structure using a spring as a restoring force. Background technique [0002] At present, most buttons use springs or silicone bumps to provide the resilience required by the keycaps. Generally speaking, most of the springs used have only a single fixed spring constant. If the spring constant is small, the resilience provided by the spring is also small, and the resistance when the user presses the keycap is also small, so that the user can quickly press the keycap. However, due to the small resilience, it takes a long time for the pressed keycap to return to its original position, which is not suitable for continuous pressing in a short period of time. If the spring constant is larger, the rebound force provided by the spring is also larger, and the pressed keycap can return to its original position in a shorter time. However, due to the large resilience, the resistance w...
