Problems solved by technology

[0004] However, when a force is applied to the slider S to push the first link L1 to force the above-mentioned button member to change from the operating state (height H) to the storage state (height H'), it is necessary to overcome the vertical deformation of the elastic element E due to compression. The elastic recovery force on the surface of the base B, so it is often more laborious to push the slider S
In addition, since the elastic element E is in a compressed state for a long time (such as Figure 1b shown), so its service life is bound to be greatly shortened
Due to the above disadvantages, the object of the present invention is to provide a lifting button member, which can adjust the height of the keycap C in a relatively labor-saving manner, which not only helps to lower the button for easy storage, but also solves the problem of shortening the life of the above-mentioned elastic elements

[0034] see first Figure 2a as well as Figure 2b , the two figures represent a schematic view of the lifting button member in the present invention. The present invention can be applied on the keyboard of notebook computer, and wherein keyboard is arranged on base 10 by a plurality of such as Figure 2a The button widget shown is composed. Such as Figure 2a As shown, the lifting button member of the present invention is mainly composed of an elastic member Q and an upper keycap 60, wherein the elastic member Q can provide an elastic force for the keycap 60 to move in the vertical direction. In this embodiment, the elastic element R is connected to the first connecting rod 40 and the slider S, wherein the slider S is provided with a stopper S3, when the slider S is at the first position X1, the first connecting rod 40 and the second slider S The two connecting rods 50 form a first angle a, and the keycap has a first height H, so that the key is in an operating state and c...

[0043] Figure 6a It shows an exploded view of some keys of a keyboard. In the second embodiment, the present invention provides a keyboard, which mainly connects the above-mentioned slider S through a slider M, and then can simultaneously control a plurality of the above-mentioned lifting key members. The slider S is fixed on the slider M, the base 10 is provided with a first chute 100, the slider M is provided with a second chute M0, and a locking member L is installed in the first chute 100 and the second chute within M0. As shown in the figure, the second chute M0 has a fixed end M0' and a movable end M0", and the above-mentioned lock member L is movably arranged in the first chute 100 and the second chute M0, thereby forming a lock Mechanism G, in order to control the movement of the slide M.

[0044] Referring next to Figure 6b, when the keyboard is not in use, the locking member L can be adjusted to the movable end M0", at this time, the slide plate M can be pushed al...

[0047] see next Figure 7 In this embodiment, the lifting button member is basically the same as that of the first embodiment, especially a guide groove S4 is provided on the slider S, and its function is equivalent to the first connection part on the base 10 in the first embodiment. 101. After assembly, the first end 41 of the first connecting rod 40 is located in the above-mentioned guide groove part S4, so it can move in the first direction A; in this way, the first end 41 can slide in the guide groove part S4 to drive the key The cap 60 is raised or lowered, and can be switched between the above-mentioned operation state and the storage state. However, it is also possible to arrange the guide groove portion S4 in such as Figure 6a On the slide plate M or the slide block S in the middle, the lift button member of the present invention can be applied to a keyboard.

Abstract

A lifting key-press block comprises a keycap, a base, first and second connecting rod, a slider and an elastic element. The elastic element connects to first connecting rod and slider; when slider is on first position, keycap has first height opposite base; the key-press is on operating state and fit user to press; when slider moves to second position, the slider drives first connecting rod, makes keycap move close to base, then the keycap is on second height opposite base and makes key-press on drew state. Elastic element moves with slider and can decrease needed force and work to make key-press down to drew state.

Description

technical field [0001] The present invention relates to a lifting button component, in particular to a lifting button component that can lower a button or a keyboard in a labor-saving manner, save space and be conveniently stored. Background technique [0002] see first Figure 1a , which shows a schematic diagram of a known key member in an operating state. For example, the well-known U.S. Patent No. 5,874,696 discloses a lifting button member, which can be pushed down by a slider in the horizontal direction. As shown in the figure, a conventional key member mainly includes a base B, a first link L1 , a second link L2 , an elastic element E, a slider S and a keycap C. As shown in FIG. Wherein, the first connecting rod L1 has a first end L11 and a second end L12, and the second connecting rod L2 has a third end L23 and a fourth end L24. In addition, the above-mentioned first link L1 and second link L2 are pivotally connected through the pivot P, wherein the first end L11 i...
