技术领域technical field
本发明提供一种具有操作手感的按键及键盘，尤指一种不使用机械式升降支撑元件，利用具支撑功能的弹性元件提供操作手感的按键及键盘。The invention provides a key and a keyboard with an operating feel, especially a key and a keyboard that do not use a mechanical lifting support element, but use an elastic element with a supporting function to provide an operating feel.
背景技术Background technique
随着科技的进步，可携式电子装置逐渐趋向超薄型的外观设计。薄型电子装置的结构空间有限，故其输入介面(例如键盘)也须有相应的薄型设计。然而薄型键盘的操作行程较短，但传统按键所需的零组件数量既多且杂，例如底板、弹性体、升降支撑结构以及键帽。升降支撑结构设置在底板上，键帽安装在升降支撑结构的顶端，弹性体设置在底板且位于升降支撑结构中。当键帽受到外力按压时，升降支撑结构支撑键帽以稳定行程相对底板移动，弹性体则在被键帽挤压时施加弹性恢复力以产生操作手感。由于传统按键的零组件数量很多，这些零组件组装起来便有一定的高度，难以适应键盘与可携式电子装置的薄型设计趋势。With the advancement of technology, portable electronic devices gradually tend to have ultra-thin appearance designs. The structural space of the thin electronic device is limited, so the input interface (such as the keyboard) must also have a corresponding thin design. However, the operation stroke of the thin keyboard is short, but the number of components required by traditional keys is large and complicated, such as the bottom plate, elastic body, lifting support structure and key cap. The lifting support structure is arranged on the bottom plate, the keycap is installed on the top of the lifting support structure, and the elastic body is arranged on the bottom plate and located in the lifting support structure. When the keycap is pressed by an external force, the lifting support structure supports the keycap to move relative to the bottom plate with a stable stroke, and the elastic body exerts an elastic restoring force when pressed by the keycap to produce an operating feel. Due to the large number of components in the traditional keypad, these components have a certain height when assembled, which is difficult to adapt to the thin design trend of keyboards and portable electronic devices.

具体实施方式Detailed ways
请参阅图1与图2，图1为本发明实施例的键盘10的示意图，图2为本发明实施例的键盘10沿剖面线A-A’的截面示意图。键盘10包含底板12以及复数个按键14。底板12上可铺设一个具有复数个开关16的薄膜电路层，开关16的数量对应于按键14的数量，且每一个按键14都设置在对应开关16的上方。按键14主要包含键帽18以及弹性元件20。弹性元件20设置在底板12、且对应于复数个开关16的其中之一。键帽18设置在弹性元件20上，利用弹性元件20的恢复变形而能相对底板12上升或下降。于本发明实施例中，按键14不需设置传统的机械式升降支撑元件，例如剪刀脚结构，弹性元件20除了在使用者按压按键14时提供操作手感外，还能利用本身的弹性恢复力支撑按键14，免除传统剪刀脚结构的冗余元件。Please refer to FIGS. 1 and 2. FIG. 1 is a schematic diagram of a keyboard 10 according to an embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view of the keyboard 10 according to an embodiment of the present invention along the section line A-A'. The keyboard 10 includes a bottom plate 12 and a plurality of keys 14 . A film circuit layer with a plurality of switches 16 can be laid on the bottom plate 12 , the number of switches 16 corresponds to the number of keys 14 , and each key 14 is arranged above the corresponding switch 16 . The button 14 mainly includes a keycap 18 and an elastic element 20 . The elastic element 20 is disposed on the bottom plate 12 and corresponds to one of the plurality of switches 16 . The keycap 18 is disposed on the elastic element 20 , and can rise or fall relative to the bottom plate 12 by utilizing the recovery deformation of the elastic element 20 . In the embodiment of the present invention, the key 14 does not need to be equipped with traditional mechanical lifting support elements, such as scissor foot structure, and the elastic element 20 can not only provide the operating feel when the user presses the key 14, but also support it with its own elastic restoring force. The button 14 eliminates the redundant elements of the traditional scissor foot structure.
如图2及图3所示，弹性元件20包含一体成型的本体部22、触发部24以及支撑部26。本体部22主要包含底座28以及侧壁30，侧壁30围绕设置于底座28上，在本体部22的中间形成内凹空间32，且内凹空间32的开口朝向键帽18。触发部24设置在本体部22的底面，意即设置在底座28上。触发部24为一短柱型结构，然不限于此，短柱型结构的两端分别突出底座28的上下两相对侧面。举例来说，触发部24的上端241伸入内凹空间32，在按键14没有受到外力按压时与键帽18相隔预设距离；触发部24的下端242较佳悬空地位于开关16的上方、或轻轻碰触到开关16。按键14受压时，键帽18向下移动抵靠于触发部24的上端241，进而带动触发部24往下移动，可使得下端242施压且触发对应的开关16。As shown in FIGS. 2 and 3 , the elastic element 20 includes a body portion 22 , a trigger portion 24 and a support portion 26 integrally formed. The main body 22 mainly includes a base 28 and a side wall 30 . The side wall 30 surrounds the base 28 and forms a concave space 32 in the middle of the main body 22 . The opening of the concave space 32 faces the keycap 18 . The trigger part 24 is disposed on the bottom surface of the body part 22 , that is, disposed on the base 28 . The trigger part 24 is a short column structure, but is not limited thereto. Two ends of the short column structure respectively protrude from the upper and lower opposite sides of the base 28 . For example, the upper end 241 of the trigger part 24 extends into the concave space 32, and is separated from the keycap 18 by a predetermined distance when the key 14 is not pressed by an external force; the lower end 242 of the trigger part 24 is preferably suspended above the switch 16, Or lightly touch switch 16. When the button 14 is pressed, the keycap 18 moves downward against the upper end 241 of the trigger part 24 , and then drives the trigger part 24 to move downward, so that the lower end 242 presses and triggers the corresponding switch 16 .
支撑部26设置在本体部22的侧面，例如连接于侧壁30的上端边，且侧壁30的下端边另连接于底座28。支撑部26的一端连接本体部22，支撑部26的另一端则撑在底板12上。支撑部26侧向承托本体部22，稳住本体部22不致倾倒，以提供升降支撑功能给键帽18；支撑部26还能够些微地托高本体部22，让位于本体部22底面的触发部24悬空在开关16的上方、或轻触开关16。一般来说，支撑部26较佳为图2所示的多弯折结构，例如双弯折或三弯折结构。由于支撑部26本身由可弹性变形材质制作而成，支撑部26的弯折结构能够提高整体弹性恢复的强度，然实际应用不限于此，亦可由任意具弹性恢复特性的机构设计所取代。The support portion 26 is disposed on the side of the main body portion 22 , for example, connected to the upper end of the side wall 30 , and the lower end of the side wall 30 is further connected to the base 28 . One end of the supporting portion 26 is connected to the main body portion 22 , and the other end of the supporting portion 26 is supported on the base plate 12 . The supporting part 26 supports the main body part 22 laterally, and stabilizes the main body part 22 so as not to fall over, so as to provide lifting support function for the keycap 18; The trigger part 24 is suspended above the switch 16 or touches the switch 16 . In general, the supporting portion 26 is preferably a multi-bend structure as shown in FIG. 2 , such as a double-bend or triple-bend structure. Since the supporting part 26 itself is made of elastically deformable material, the bending structure of the supporting part 26 can improve the strength of the overall elastic recovery.
请参阅图3与图4，图3为本发明实施例的弹性元件20的示意图，图4为本发明实施例的弹性元件20的剖视图。由图中可清楚看出，底座28与侧壁30结合形成倒U型的内凹空间32，且内凹空间32的开口朝向键帽18(请参照图2)。触发部24的上端241离内凹空间32的开口尚有一段距离，使用者按压按键14达一定行程才能推挤触发部24向下移动以触发开关16。支撑部26除了以其两端分别连接本体部22与底板12，支撑部26的侧面和本体部22之间形成中空区域，可以薄化支撑部26的结构厚度而产生充分的弹性恢复力。特别一提的是，本实施例的支撑部26环设在本体部22的周缘，在各个方向都能提供稳定支撑力给本体部22。Please refer to FIG. 3 and FIG. 4 , FIG. 3 is a schematic diagram of the elastic element 20 according to the embodiment of the present invention, and FIG. 4 is a cross-sectional view of the elastic element 20 according to the embodiment of the present invention. It can be clearly seen from the figure that the base 28 and the side wall 30 combine to form an inverted U-shaped concave space 32 , and the opening of the concave space 32 faces the keycap 18 (please refer to FIG. 2 ). The upper end 241 of the trigger part 24 is still a certain distance away from the opening of the concave space 32 , and the user can push the trigger part 24 to move down to trigger the switch 16 after pressing the button 14 for a certain distance. In addition to connecting the main body 22 and the bottom plate 12 at both ends of the supporting part 26, a hollow area is formed between the side of the supporting part 26 and the main body 22, which can thin the structural thickness of the supporting part 26 and generate sufficient elastic recovery force. In particular, the support portion 26 of this embodiment is disposed around the periphery of the body portion 22 to provide stable support for the body portion 22 in all directions.
请参阅图5，图5为本发明另一实施例的弹性元件20’的示意图。相较于图3及图4所示弹性元件20，本实施例的弹性元件20’包含复数个支撑部26’，分别以对称方式设置在本体部22的周缘。复数个支撑部26’亦可不对称地分设在本体部22的周缘。每一个支撑部26’都可以是前述实施例提及的可弹性变形材质制作的多弯折结构，差别在于支撑部26’为条状构件，自不同方向分别从本体部22向外对称延伸，藉此减少材料使用量及减轻弹性元件20’的整体重量，有利于节约产品成本。Please refer to FIG. 5 . FIG. 5 is a schematic diagram of an elastic element 20' according to another embodiment of the present invention. Compared with the elastic element 20 shown in FIG. 3 and FIG. 4 , the elastic element 20' of this embodiment includes a plurality of support portions 26', which are respectively symmetrically arranged on the periphery of the main body portion 22. A plurality of supporting parts 26' can also be asymmetrically arranged on the periphery of the main body part 22. Each supporting part 26' can be a multi-bending structure made of elastically deformable material mentioned in the previous embodiment, the difference is that the supporting part 26' is a strip-shaped member, which extends symmetrically from the main body part 22 in different directions. In this way, the amount of materials used and the overall weight of the elastic element 20' can be reduced, which is beneficial to saving product costs.
综上所述，本发明在弹性元件的本体部周边延伸设置支撑部以承托本体部及位于其上的触发部，支撑部和本体部都是由可弹性变形材质制作，且支撑部较佳一体成型于本体部；因此支撑部可取代传统的机械式升降支撑元件，让弹性元件既能提供使用者操作手感，也能施加支撑力量予键帽而省去冗余元件的材料成本。相较现有技术，本发明的具有支撑功能的弹性元件、及具有弹性元件的相关按键及键盘能有效减少元件数量、节约制造成本、及提高组装速度与精确度。To sum up, in the present invention, a support part is extended around the body part of the elastic element to support the body part and the trigger part on it. Both the support part and the body part are made of elastically deformable materials, and the support part is preferably It is integrally formed on the main body; therefore, the support part can replace the traditional mechanical lifting support element, so that the elastic element can not only provide the user with an operating feel, but also apply support force to the keycap, saving the material cost of redundant components.
