Abstract

本发明提供一种键盘，包括具有连接架的底板、翼式连接元件以及按键帽。翼式连接元件的第一连接轴伸入连接架而连接翼式连接元件以及底板。当按键帽被触压时，第一连接轴伸入连接架的第一容纳空间内而作为摆动的支点，由于翼式连接元件的垂直移动受第一容纳空间限制，使翼式连接元件摆动的幅度较小，因此，本发明键盘可改善按键帽的触压稳定度。

The present invention provides a keyboard, comprising a base plate with a connecting frame, a wing-type connecting element and a key cap. A first connecting shaft of the wing-type connecting element extends into the connecting frame to connect the wing-type connecting element and the base plate. When the key cap is pressed, the first connecting shaft extends into a first accommodating space of the connecting frame and serves as a fulcrum for swinging. Since the vertical movement of the wing-type connecting element is limited by the first accommodating space, the swinging amplitude of the wing-type connecting element is small. Therefore, the keyboard of the present invention can improve the touch stability of the key cap.

Description

键盘keyboard

技术领域technical field

本发明涉及一种输入装置，尤其涉及一种包含有多个按键结构的键盘。The present invention relates to an input device, in particular to a keyboard comprising a plurality of key structures.

背景技术Background technique

常见的电脑周边输入装置包括鼠标、键盘以及轨迹球等，其中键盘可直接键入文字以及符号予电脑，因此相当受到使用者以及输入装置厂商的重视。其中，较为常见的是一种包含有多个按键结构的键盘。Common computer peripheral input devices include mouse, keyboard, trackball, etc. Among them, the keyboard can directly input characters and symbols to the computer, so it is highly valued by users and input device manufacturers. Among them, the more common one is a keyboard including a plurality of key structures.

接下来说明键盘中的按键结构的架构，以包含有剪刀式连接元件的按键结构为例说明。请参阅图1，其为公知按键结构的剖面侧视示意图。公知按键结构1包括按键帽11、剪刀式连接元件12、弹性橡胶体13、薄膜开关电路14以及底板15，且底板15用以承载按键帽11、剪刀式连接元件12、弹性橡胶体13以及薄膜开关电路14。其中剪刀式连接元件12是用以连接底板15与按键帽11。Next, the structure of the key structure in the keyboard will be described, taking the key structure including the scissor-type connecting element as an example. Please refer to FIG. 1 , which is a schematic cross-sectional side view of a conventional key structure. The conventional key structure 1 includes a key cap 11 , a scissor-type connecting element 12 , an elastic rubber body 13 , a membrane switch circuit 14 and a bottom plate 15 , and the bottom plate 15 is used to carry the key cap 11 , the scissors-type connecting element 12 , the elastic rubber body 13 and the membrane switch circuit 14 . The scissor-type connecting element 12 is used to connect the bottom plate 15 and the key cap 11 .

剪刀式连接元件12位于底板15以及按键帽11之间且分别连接二者。剪刀式连接元件12包括第一框架121以及第二框架122。第一框架121的第一端连接于按键帽11，而第一框架121的第二端则连接于底板15。弹性橡胶体13被剪刀式连接元件12环绕，而薄膜开关电路14具有多个按键接点(未显示于图中)。该按键接点于被触发时输出相对应的按键信号。弹性橡胶体13设置于薄膜开关电路14上且一个弹性橡胶体13对应于一个按键接点，当弹性橡胶体13被触压时，弹性橡胶体13发生形变且触压薄膜开关电路14中相对应的按键接点而产生按键信号。The scissor-type connecting element 12 is located between the bottom plate 15 and the key cap 11 and connects the two respectively. The scissor-type connecting element 12 includes a first frame 121 and a second frame 122 . The first end of the first frame 121 is connected to the key cap 11 , and the second end of the first frame 121 is connected to the bottom plate 15 . The elastic rubber body 13 is surrounded by the scissor-type connecting element 12, and the membrane switch circuit 14 has a plurality of key contacts (not shown in the figure). The button contact outputs a corresponding button signal when triggered. The elastic rubber body 13 is arranged on the membrane switch circuit 14, and one elastic rubber body 13 corresponds to a key contact. When the elastic rubber body 13 is pressed, the elastic rubber body 13 is deformed and the corresponding button in the membrane switch circuit 14 is touched. Press the key contact to generate a key signal.

接下来说明公知按键结构1被使用者触压的运作情形。图1中，当使用者触压按键帽11时，按键帽11受力而推抵剪刀式连接元件12使其运动，故按键帽11可相对于底板15往下移动且触压相对应的弹性橡胶体13。此时，弹性橡胶体13发生形变且触压薄膜开关电路14以触发薄膜开关电路14的按键接点，使得薄膜开关电路14输出相对应的按键信号。而当使用者停止触压按键帽11时，按键帽11不再受力而停止触压弹性橡胶体13，使得弹性橡胶体13根据其弹性而恢复原状，同时提供往上的弹性恢复力，按键帽11因此而被推回被触压之前的位置。上述为公知按键结构的结构以及运作情形。Next, the operation of the conventional key structure 1 being pressed by the user will be described. In FIG. 1, when the user touches the key cap 11, the key cap 11 is forced to push against the scissor-type connecting element 12 to make it move, so the key cap 11 can move downward relative to the bottom plate 15 and press the corresponding elasticity Rubber body 13 . At this time, the elastic rubber body 13 deforms and touches the membrane switch circuit 14 to trigger the button contacts of the membrane switch circuit 14, so that the membrane switch circuit 14 outputs a corresponding button signal. When the user stops pressing the button cap 11, the button cap 11 is no longer under force and stops pressing the elastic rubber body 13, so that the elastic rubber body 13 returns to its original state according to its elasticity, and at the same time provides an upward elastic restoring force. The cap 11 is thus pushed back to the position before being pressed. The above is the structure and operation of the conventional key structure.

于按键帽11被触压的过程中，第一框架121以及第二框架122随着移动的按键帽摆动，且第一框架121以及第二框架122于摆动的同时亦发生晃动，造成按键帽11的移动亦随之晃动而不稳定。When the key cap 11 is pressed, the first frame 121 and the second frame 122 swing with the moving key cap, and the first frame 121 and the second frame 122 also shake while swinging, causing the key cap 11 The movement is also swaying and unstable.

因此，需要一种可提升触压稳定度的键盘。Therefore, there is a need for a keyboard with improved touch stability.

FIG. 4 is a schematic diagram of a partial structure of the keyboard of the present invention in a preferred embodiment, and FIG. 5 is a schematic cross-sectional side view of a partial structure of the keyboard of the present invention in a preferred embodiment. 6 is a schematic cross-sectional side view of a partial structure of the keyboard of the present invention being pressed in a preferred embodiment. 4 and 5 show the combination of the components, the first connecting shaft 2311 and the first sliding shaft 2314 of the first frame 231 extend into the corresponding connecting frame 211 , and the second connecting shaft 2312 extends into the key cap 22 The third connecting shaft 2321 and the second sliding shaft 2323 of the second frame 232 extend into the corresponding connecting frame 211, and the fourth connecting shaft 2322 extends into the corresponding connecting frame 221 of the key cap 22. inside the hook 221.

当使用者触压按键帽22时，按键帽22相对于底板21垂直往下移动且推抵第二连接轴2312以及第四连接轴2322，使第一框架231以第一连接轴2311为支点相对于底板21摆动，且第一连接轴231于第一容纳空间2311A内垂直移动，而第一滑动轴2314于第二容纳空间2311B内水平移动以及转动。另一方面，第二框架232以与第一框架231连接的第三连接轴2321为支点相对于底板21摆动，且第三连接轴2321随着第一连接轴2311垂直移动，而第二滑动轴2323于第三容纳空间211C内水平移动以及转动。When the user touches the key cap 22, the key cap 22 moves vertically downward relative to the bottom plate 21 and pushes against the second connecting shaft 2312 and the fourth connecting shaft 2322, so that the first frame 231 is opposite to the first connecting shaft 2311 as a fulcrum The bottom plate 21 swings, and the first connecting shaft 231 moves vertically in the first accommodating space 2311A, and the first sliding shaft 2314 moves and rotates horizontally in the second accommodating space 2311B. On the other hand, the second frame 232 swings relative to the bottom plate 21 with the third connecting shaft 2321 connected to the first frame 231 as a fulcrum, and the third connecting shaft 2321 moves vertically along with the first connecting shaft 2311, while the second sliding shaft 2323 moves and rotates horizontally in the third accommodating space 211C.

接下来，往下移动的按键帽22抵顶弹性元件25，且弹性元件25受力而变更为压缩状态，同时抵顶开关电路板24且触发之，使开关电路板24输出对应于按键帽22的按键信号。而当弹性元件25不再被按键帽22推抵时，弹性元件25由压缩状态恢复，同时提供一弹性力予按键帽22，使按键帽22垂直往上移动而恢复至未触压前的位置，且垂直往上移动的按键帽22带动第一框架231以及第二框架232摆动，以回复为图5的状态。Next, the downward moving button cap 22 pushes against the elastic element 25 , and the elastic element 25 is forced to change to a compressed state, and at the same time pushes against the switch circuit board 24 and triggers it, so that the output of the switch circuit board 24 corresponds to the button cap 22 button signal. When the elastic element 25 is no longer pushed by the button cap 22, the elastic element 25 recovers from the compressed state, and at the same time provides an elastic force to the button cap 22, so that the button cap 22 moves vertically upwards and returns to the position before being pressed , and the key cap 22 that moves vertically upward drives the first frame 231 and the second frame 232 to swing, so as to return to the state of FIG. 5 .

需特别说明的是，连接架211中，第一容纳空间211A、第二容纳空间211B以及第三容纳空间211C形成类似凸字形的形状，以供第一连接轴231于第一容纳空间2311A内垂直移动，且令第一滑动轴2314于第二容纳空间2311B内水平移动以及转动，第二滑动轴2323于第三容纳空间211C内水平移动以及转动。其中，按键帽22的移动行程可根据第一容纳空间211A的高度而决定，若有按键帽22的移动行程变大的需求，可采用增加第一容纳空间211A的高度的设计，以增加按键帽22的移动行程。反之，若有按键帽22的移动行程变小的需求，则可采用降低第一容It should be noted that, in the connecting frame 211 , the first accommodating space 211A, the second accommodating space 211B and the third accommodating space 211C are shaped like a convex shape, so that the first connecting shaft 231 is perpendicular to the first accommodating space 2311A The first sliding shaft 2314 moves and rotates horizontally in the second accommodating space 2311B, and the second sliding shaft 2323 moves and rotates horizontally in the third accommodating space 211C. The movement stroke of the key cap 22 can be determined according to the height of the first accommodating space 211A. If the movement stroke of the key cap 22 becomes larger, a design of increasing the height of the first accommodating space 211A can be adopted to increase the key cap 22 travel strokes. On the contrary, if there is a need to reduce the movement stroke of the key cap 22, the first capacity can be reduced.

根据上述可知，本发明键盘采用翼式连接元件分别连接于底板以及按键帽，且通过特殊形状的连接架而结合底板以及翼式连接元件。根据翼式连接元件以及连接架的结构，使得翼式连接元件摆动的幅度小于传统剪刀式连接元件的摆动幅度。与传统剪刀式连接元件相比，本发明键盘的翼式连接元件摆动幅度小，故可稳定地摆动，进而提升按键帽的触压稳定度，同时，亦可降低键盘的厚度。另一方面，于按键帽被触压的过程中，翼式连接元件的第一连接轴伸入连接架内而作为摆动的支点，故翼式连接元件的垂直移动可受第一容纳空间的高度限制，以控制第一连接轴垂直移动的幅度，也就是说，本发明键盘可控制按键帽的移动行程。As can be seen from the above, the keyboard of the present invention adopts wing-type connecting elements to connect to the bottom plate and the key cap respectively, and combines the bottom plate and the wing-type connecting elements through a special-shaped connecting frame. According to the structure of the wing-type connecting element and the connecting frame, the swinging amplitude of the wing-type connecting element is smaller than that of the traditional scissors-type connecting element. Compared with the traditional scissor-type connection element, the wing-type connection element of the keyboard of the present invention has a small swing range, so it can swing stably, thereby improving the touch pressure stability of the key cap, and at the same time, the thickness of the keyboard can also be reduced. On the other hand, when the key cap is pressed, the first connecting shaft of the wing-type connecting element extends into the connecting frame to serve as a pivot point for swinging, so the vertical movement of the wing-type connecting element can be affected by the height of the first accommodating space limit to control the vertical movement range of the first connecting shaft, that is to say, the keyboard of the present invention can control the movement stroke of the key cap.
