Embodiment Construction

[0046] see figure 2 , Figure 3A and Figure 3B , figure 2 The elastic actuator 2 of the first preferred embodiment of the present invention is schematically shown in an external view. Figure 3A for figure 2 The cross-sectional view of the elastic actuator 2 along the section line A-A when the elastic actuator 2 is not pressed by an external force. Figure 3B for figure 2 Another cross-sectional view along the A-A section line when the elastic actuator 2 is in a state of being pressed by an external force. The elastic actuator 2 of the first preferred embodiment of the present invention can be disposed between the keycap 29 and the bottom plate. At Figure 3A , Figure 3B In , only a partial sectional view of the keycap 29 is shown, and the bottom plate is not shown.

[0047] Such as figure 2 , Figure 3A and Figure 3B As shown, the elastic actuator 2 of the first preferred embodiment of the present invention includes an elastic body 20 , a platform 22 , a p...

Abstract

The invention relates to a resilient actuator and a dome sheet, a keyswitch and a keyboard with the resilient actuator. In a preferred concrete embodiment, the resilient actuator contains an elastomer, a platform, a raised column and an actuation column. The platform is formed on the top of the elastomer and is provided with a first top end. The raised column is formed at the central position of the top of the elastomer and is equipped with a second top end. The second top end is higher than the first top end. The actuation column is formed in the elastomer. According to the resilient actuator and the dome sheet, the keyswitch and the keyboard with the resilient actuator, the resilient actuator is provided with the raised column, a raised body or a ring-like body, the top of which is higher than the top of the platform. Thus, the resilient actuator provided by the invention has a structure of increasing peak stroke. In comparison with the prior art, force-stroke characteristic and peak stroke are both raised, and then pressing handfeel of the keyswitch provided with the resilient actuator is improved.

Description

technical field [0001] The present invention relates to a resilient actuator (resilient actuator) and a dome sheet (dome sheet), a key (keyswitch) and a keyboard (keyboard) comprising the resilient actuator, and particularly relates to a travel) to increase the elastic actuator to improve the pressing feel of the button installed with the elastic actuator. Background technique [0002] see Figure 1A and Figure 1B . Figure 1A It is a sectional view of the keyboard 1 of the prior art. Figure 1B for Figure 1A Partial sectional view of middle button 10. [0003] Such as Figure 1A As shown, the keyboard 1 includes a base body 13 and a plurality of keys 10 . A plurality of keys 10 are generally disposed in the base body 13 , and have their own keycaps 14 exposed to the base body 13 for the user to press. [0004] Such as Figure 1B As shown, the button 10 includes a substrate 11 , a membrane switch 12 , a keycap 14 , a scissor-like supporting device 16 and an elastic ac...
