Description
本發明關於一種按鍵裝置,尤指一種將彈性體分別設置在對應鍵帽之中間按壓區段以及側邊按壓區段之位置的按鍵裝置。 The present invention relates to a key device, in particular to a key device in which elastic bodies are respectively arranged at the positions of the middle pressing section and the side pressing section corresponding to the keycap.
就目前個人電腦的使用習慣而言,鍵盤為不可或缺的輸入設備之一,用以輸入文字、符號或數字。不僅如此,舉凡日常生活所接觸的消費性電子產品或是工業界使用的大型加工設備,皆需設有按鍵結構作為輸入裝置,以操作上述之電子產品與加工設備。 As far as the current usage habits of personal computers are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Not only that, for example, consumer electronic products that are in contact with daily life or large-scale processing equipment used in the industry, all need to have a key structure as an input device to operate the above-mentioned electronic products and processing equipment.
傳統按鍵的上下運動的距離較長,故可輕易地於其鍵帽下方設置彈性體(如碗形橡膠體),使得當鍵帽被向下按壓時,彈性體亦被向下壓縮而產生彈力,而當鍵帽被釋放時,彈性體產生之彈力驅使鍵帽向上移動以回復原位。然而,對於較長按鍵(又稱倍數按鍵,例如空白(Space)鍵、輸入(Enter)鍵、大寫(Caps Lock)鍵、位移(Shift)鍵等)而言,其鍵帽通常具有較大的長寬比,使得鍵帽整體的剛性較弱。因此,在按壓此類按鍵的鍵帽邊角時,鍵帽通常會產生局部形變(例如鍵帽中間產生向上撓曲變形),導致設置在鍵帽中間下方的彈性體無法被確實地按壓變形而造成按鍵按壓觸發延遲甚至失效的問題,如此就會容易讓使用者感受到按壓觸發不夠靈敏且不一致的按壓手感。 The distance of up and down movement of traditional keys is long, so it is easy to set an elastic body (such as a bowl-shaped rubber body) under the key cap, so that when the key cap is pressed down, the elastic body is also compressed downward to generate elastic force , and when the keycap is released, the elastic force generated by the elastic body drives the keycap to move up to return to its original position. However, for longer keys (also known as multiple keys such as Space, Enter, Caps Lock, Shift, etc.), the keycaps usually have larger The aspect ratio makes the overall rigidity of the keycap weaker. Therefore, when the corners of the keycaps of such keys are pressed, the keycaps usually undergo local deformation (for example, upward deflection deformation occurs in the middle of the keycaps), so that the elastic body disposed under the middle of the keycaps cannot be reliably pressed and deformed. The problem of delay or even failure of the button pressing trigger is caused, which will easily make the user feel that the pressing trigger is not sensitive enough and inconsistent.
因此,本發明的目的之一在於提供一種將彈性體分別設置在對應鍵帽之中間按壓區段以及側邊按壓區段之位置的按鍵裝置,以解決上述問題。 Therefore, one of the objectives of the present invention is to provide a key device in which elastic bodies are respectively disposed at the positions corresponding to the middle pressing section and the side pressing section of the keycap, so as to solve the above problems.

請參閱第1圖、第2圖,以及第3圖,第1圖為根據本發明之一實施例所提出之一按鍵裝置10之部分爆炸示意圖,第2圖為第1圖之按鍵裝置10於組裝後沿著剖面線A-A之部分剖面示意圖,第3圖為第1圖之按鍵裝置10於組裝後沿著剖面線A-A之另一部分剖面示意圖。如第1圖、第2圖,以及第3圖所示,按鍵裝置10係可應用在一般常見之鍵盤(如筆記型電腦鍵盤或折疊式鍵盤裝置)上且可較佳地為具有較長按鍵長度的鍵盤按鍵(如倍數按鍵,但不以此為限),按鍵裝置10包含一鍵帽12、一底板14、一薄膜電路板16、一第一彈性體18,以及一第二
彈性體20。鍵帽12具有一中間按壓區段22以及至少一側邊按壓區段24(於第1圖中顯示二個,但不受此限,以下僅針對位於鍵帽12之右側邊之側邊按壓區段24的觸發設計進行詳細描述,至於針對位於左側邊之側邊按壓區段24的相關描述,其係可以此類推,於此不再贅述)。底板14係與鍵帽12相對設置。薄膜電路板16係設置於底板14上且與鍵帽12之一帽緣底面26相距一按壓行程T(也就是可允許使用者按壓的最大行程),其中薄膜電路板16對應中間按壓區段22之位置具有一第一觸發開關28且對應側邊按壓區段24之位置具有一第二觸發開關30。第一彈性體18(較佳地為橡膠彈性體(rubber dome),但不受此限,其亦可為其他能夠提供回位彈力至鍵帽12的彈性件,如彈簧等)係抵接於中間按壓區段22與薄膜電路板16之間,藉此,第一彈性體18可提供彈性力以供鍵帽12自動回位,且可在中間按壓區段22被按壓時產生撓曲變形以觸發第一觸發開關28,從而執行對應的輸入功能。
Please refer to FIG. 1, FIG. 2, and FIG. 3. FIG. 1 is a partial exploded schematic diagram of a
至於在第二彈性體20之設計方面,由第2圖可知,第二彈性體20係設置於側邊按壓區段24與薄膜電路板16之間且具有一抵接頂面32以及一觸發底面34,其中第二彈性體20係可較佳地具有一環形底座38、一橋接結構40,以及一中間柱體42(但不受此限),橋接結構40係可自環形底座38向上延伸連接至中間柱體42,以支撐中間柱體42相對於第二觸發開關30懸空,中間柱體42可具有抵接頂面32以及觸發底面34。更詳細地說,在此實施例中,當鍵帽12未被按壓時,抵接頂面32與鍵帽12之一按壓底面36相距一垂直距離D1,而當鍵帽12被按壓垂直距離D1以使按壓底面36接觸抵接頂面32且繼續下壓一觸發行程D2時,第二彈性體20係可產生撓曲變形,使得觸發底面34抵壓觸發第二觸發開關30而執行對應的輸入功能,其中垂直距離D1與觸發行程D2之和除以按壓行程T之比值係可較佳地介於0.6~0.95之間,藉以避免第二觸發開關30觸發過早或過晚的情況發生,也就是說,透過上述設計,按鍵裝置10係可在使用者按壓側邊按壓區段24以經由第二彈
性體20觸發第二觸發開關30時,提供與使用者按壓中間按壓區段22時(此時,鍵帽12可經由第一彈性體18觸發第一觸發開關28)相對一致的按壓觸發手感。
As for the design of the second
綜上所述,透過在對應鍵帽12之中間按壓區段22以及側邊按壓區段24之位置分別配置第一彈性體18以及第二彈性體20之設計,無論使用者是按壓鍵帽12之中間按壓區段22或者是按壓側邊按壓區段24,本發明係可透過第一彈性體18觸發第一觸發開關28或第二彈性體20觸發第二觸發開關30之方式來確實地完成按鍵裝置10之按壓觸發操作,並且可透過上述垂直距離D1與觸發行程D2以及按壓行程T之比值設計,提供觸發時間相對一致的按壓觸發手感,如此一來,本發明係可有效地解決先前技術中所提到之倍數按鍵在鍵帽邊角被按壓時容易造成按鍵按壓觸發延遲甚至失效的問題,進而讓使用者感受到按壓觸發靈敏且相對一致的按壓手感。
To sum up, through the design of disposing the first
值得一提的是,為了避免額外設置的第二彈性體20所提供之彈性回復力會影響到按鍵裝置10整體的按壓手感,本發明係可採用限制第二彈性體20之彈性回復力大小的設計,舉例來說,請參閱第1圖、第2圖、第3圖,以及第4圖,第4圖為第2圖之第一彈性體18以及第二彈性體20之彈性回復力與按壓行程的關係圖。由第1圖至第4圖可知,第二彈性體20之高度H2係可較佳地小於第一彈性體18之高度H1,且當鍵帽12被按壓垂直距離D1以及繼續下壓按壓行程D2時,第一彈性體18係可提供一第一彈性回復力F1至鍵帽12,而第二彈性體20則是可提供一第二彈性回復力F2至鍵帽12,在此實施例中,第二彈性回復力F2與第一彈性回復力F1之比值係可不大於0.3,更進一步地,第二彈性回復力F2係可較佳地小於20gf(但不受此限),藉以達到避免增加或影響按鍵裝置10整體按壓手感的功效。
It is worth mentioning that, in order to avoid the elastic restoring force provided by the additionally disposed second
除此之外,本發明係可採用第二彈性體20在接觸第二觸發開關30前提供線性彈性回復力的設計,舉例來說,請參閱第2圖以及第5圖,第5圖為第2
圖之第二彈性體20之彈性回復力與按壓行程的關係圖,如第2圖以及第5圖所示,第二彈性體20之橋接結構40係可為一環形階梯狀結構(但不受此限,其亦可採用其他橋接結構設計,例如環形斜面結構)且自環形底座38向上延伸連接至中間柱體42,以支撐中間柱體42相對於第二觸發開關30懸空一垂直距離D3,垂直距離D3係可較佳地不大於0.2mm(如0.1mm,但不受此限),以確保橋接結構40在第二彈性體20在接觸第二觸發開關30前不會產生結構挫曲崩潰(buckle),也就是說,第二彈性體20係可在受壓接觸第二觸發開關30前,提供線性彈性回復力至鍵帽12而不會產生段落感,進而有效地提升按鍵裝置10之鍵帽按壓手感。另外,本發明亦可採用限制第二彈性體20之柱體厚度大小的設計以達到上述功效,舉例來說,由第2圖可知,中間柱體42可具有一火山口結構44且向下延伸形成有一觸發柱46,觸發柱46之一厚度TH與第二彈性體20之高度H2的比值係可較佳地等於0.5(但不受此限,其亦可採用小於0.5之設計,如0.4),以限制中間柱體42相對於第二觸發開關30懸空的垂直距離D3可介於使橋接結構40在第二彈性體20接觸第二觸發開關30前不會產生結構挫曲崩潰的範圍內,從而確保第二彈性體20可在受壓接觸第二觸發開關30前提供線性彈性回復力至鍵帽12,如此即可同樣地達到提升按鍵裝置10之鍵帽按壓手感的功效。
In addition, the present invention can adopt a design in which the second
在實際應用中,本發明係可進一步地採用限制中間柱體42在橋接結構40產生挫曲崩潰後所提供之彈性回復力大小的設計,以使中間柱體42可確實地觸發第二觸發開關30,舉例來說,請參閱第2圖、第5圖以及第6圖,第6圖為第2圖之按鍵裝置10於鍵帽12被下壓按壓行程T時之部分剖面示意圖。由第2圖、第5圖以及第6圖可知,由於橋接結構40係會在鍵帽12從第2圖之位置被下壓按壓行程T時產生結構挫曲崩潰(如第6圖所示),使得中間柱體42之彈性回復力下降而僅能提供一彈性回復力f1(如第5圖所示),因此,為了確保第二觸發開關30仍可被中間柱體42所觸發,在此實施例中,中間柱體42於橋接結構40受壓挫曲崩潰後所
產生之彈性回復力f1係可較佳地大於觸發第二觸發開關30之一設定觸發力f2(如10gf,但不受此限),藉以避免按鍵裝置10在使用者按壓鍵帽12的過程中出現觸發失效的情況。
In practical applications, the present invention can further adopt a design that limits the elastic restoring force provided by the
需注意的是,上述垂直距離與觸發行程以及按壓行程之比值設計、彈性回復力比值設計、柱體懸空垂直距離設計,以及柱體厚度比值設計係為可至少擇一實施之配置,也就是說,透過將第一彈性體以及第二彈性體分別設置在對應鍵帽之中間按壓區段以及側邊按壓區段之位置的設計,再加上可將上述設計之至少其中之一應用在按鍵裝置上,本發明係可有效地解決先前技術中所提到之倍數按鍵在鍵帽邊角被按壓時容易造成按鍵按壓觸發延遲甚至失效以及按壓手感受影響的問題,至於採用何種設計或其組合,其端視按鍵裝置之實際應用而定,並不以上述實施例為限。 It should be noted that the design of the ratio of the vertical distance to the trigger stroke and the pressing stroke, the design of the ratio of the elastic restoring force, the design of the vertical distance of the suspended column, and the design of the ratio of the thickness of the column are all configurations that can be implemented at least one, that is to say. , through the design of disposing the first elastic body and the second elastic body at the positions of the middle pressing section and the side pressing section of the corresponding keycap respectively, and at least one of the above designs can be applied to the key device In the above, the present invention can effectively solve the problems mentioned in the prior art that multiple keys are easily triggered by the keycap when the corners of the keycap are pressed, causing delay or even failure of the keypress triggering, as well as the influence of the pressing hand. As for which design or combination to use , which depends on the actual application of the key device, and is not limited to the above-mentioned embodiment.
