本案係關於一種鍵盤結構,尤指一種具有排氣閥座及泵浦裝置,且可升降之鍵盤結構。The present invention relates to a keyboard structure, and more particularly to a keyboard structure having an exhaust valve seat and a pumping device and capable of lifting and lowering.

於現今資訊化時代中,電腦已成為每個人生活中不可或缺的電子資訊產品。與使用者最直接相關的,就是電腦的週邊輸入裝置,包括:滑鼠、鍵盤、手寫板…等,其中,鍵盤裝置可供使用者直接鍵入文字及符號,並可透過鍵盤於電腦中進行種種文書檔案之撰寫及編輯作業,是以幾乎所有的電腦都需配置鍵盤,以供使用者便於輸入文字及符號,顯見鍵盤之重要性。In today's information age, computers have become an indispensable electronic information product for everyone's life. The most directly related to the user is the peripheral input device of the computer, including: mouse, keyboard, tablet, etc., wherein the keyboard device allows the user to directly input text and symbols, and can be used in the computer through the keyboard. The writing and editing of the document file is based on the fact that almost all computers need to be equipped with a keyboard for the user to input text and symbols, and the importance of the keyboard is obvious.

請參閱第1圖,其係為習知鍵盤之外觀示意圖。如圖所示,鍵盤1係適用於一筆記型電腦,且具有底板11以及複數個按鍵10,該等複數個按鍵10之配置方式會因各家廠商之設計而有所不同,然其主要係分別對應於不同之英文/中文字母、數字及符號等,俾用以供使用者以手指按壓該等按鍵10,進而以觸發相對應之訊號,並可於電腦中執行其對應之功能。Please refer to FIG. 1 , which is a schematic diagram of the appearance of a conventional keyboard. As shown in the figure, the keyboard 1 is suitable for a notebook computer, and has a bottom plate 11 and a plurality of buttons 10. The configuration of the plurality of buttons 10 varies according to the design of each manufacturer, but the main system is Corresponding to different English/Chinese letters, numbers and symbols, etc., respectively, for the user to press the buttons 10 with a finger, thereby triggering the corresponding signals, and performing corresponding functions in the computer.

請參閱第2圖,其為習知鍵盤之剖面結構示意圖。如圖所示,鍵盤1具有底板11及複數個按鍵10,其中每一按鍵10係由按鍵帽101、剪刀式連接元件102及彈性元件103所構成,剪刀式連接元件102連接於按鍵帽101,彈性元件103則對應於按鍵帽101而設置。按鍵1之底板11則依序包括薄膜開關電路12、間隔件13、支撐板14及下殼體15等結構,但不以此為限,其中薄膜開關電路12係包括上線路板121 、隔離層122 以及下線路板123,且上線路板121、隔離層122以及下線路板123皆係以透光材料所製成,但亦不以此為限。以及,於薄膜開關電路12中更具有複數按鍵開關124,且該等按鍵開關124係對應於每一彈性元件103之中心位置 ,是以當使用者按壓按鍵10之按鍵帽101時,則會產生向下之應力,而使剪刀式連接元件102隨之拉伸擺動,並使按鍵帽101向下壓迫彈性元件103,使彈性元件103受應力而產生形變,進而可觸壓薄膜閉關電路12之按鍵開關124,並輸出該按鍵10所對應之按鍵訊號。Please refer to FIG. 2, which is a schematic cross-sectional view of a conventional keyboard. As shown in the figure, the keyboard 1 has a bottom plate 11 and a plurality of buttons 10, wherein each button 10 is composed of a button cap 101, a scissor-type connecting member 102 and an elastic member 103, and the scissor-type connecting member 102 is connected to the button cap 101. The elastic member 103 is provided corresponding to the button cap 101. The bottom plate 11 of the button 1 includes the structure of the membrane switch circuit 12, the spacer 13, the support plate 14 and the lower casing 15 in sequence, but not limited thereto, wherein the membrane switch circuit 12 includes the upper circuit board 121 and the isolation layer. 122 and the lower circuit board 123, and the upper circuit board 121, the isolation layer 122, and the lower circuit board 123 are all made of a light-transmitting material, but are not limited thereto. Moreover, the plurality of button switches 124 are further provided in the membrane switch circuit 12, and the button switches 124 correspond to the center position of each of the elastic members 103, so that when the user presses the button cap 101 of the button 10, The downward stress causes the scissor-type connecting member 102 to be stretched and swayed, and the button cap 101 presses the elastic member 103 downward, so that the elastic member 103 is deformed by stress, and the button of the film closing circuit 12 can be pressed. The switch 124 outputs the button signal corresponding to the button 10.

又如第2圖所示,底板11之支撐板14係對應設置於薄膜開關電路12之下,以用於支撐薄膜開關電路12,下殼體15則對應設置於支撐板14之下,以作為保護支撐板14及薄膜開關電路12之用。於某些習知技術中,間隔件13則設置於薄膜開關電路12之上,且對應設置於每一按鍵10之間,且兩相鄰之間隔件13之間係具有容置空間131,用以供每一相對應之按鍵10之剪刀式連接元件102及彈性元件103設置於其中。是以,如圖所示,習知之鍵盤1的按鍵10之按鍵帽101會因剪刀式連接元件102及彈性元件103之支撐而高於間隔件13,而當使用者按壓其按鍵帽101時,則會如前所述,使剪刀式連接元件102對應拉伸擺動,且彈性元件103對應向下形變而觸發按鍵開關124,並可輸出對應之按鍵訊號,此時按鍵帽101會因使用者之按壓應力而向下降低高度,俾使按鍵帽101下沉至間隔件13之容置空間131中;然而,當使用者停止按壓該按鍵帽101時,彈性元件103則會因應該彈性恢復力而向上形變,進而停止觸發按鍵開關124,即可停止輸出該按鍵訊號,此時按鍵帽101會因彈性元件103之形變推動而向上位移復位,剪刀式連接元件102亦會被按鍵帽101帶動並回復其初始狀態,是以,按鍵帽101最終會回復至其高於間隔件13之位置。As shown in FIG. 2, the support plate 14 of the bottom plate 11 is correspondingly disposed under the membrane switch circuit 12 for supporting the membrane switch circuit 12, and the lower casing 15 is correspondingly disposed under the support plate 14 to serve as The support plate 14 and the membrane switch circuit 12 are protected. In some prior art, the spacers 13 are disposed on the membrane switch circuit 12, and are disposed between each of the buttons 10, and have an accommodation space 131 between the two adjacent spacers 13 for use. A scissor-type connecting member 102 and an elastic member 103 for each corresponding button 10 are disposed therein. Therefore, as shown in the figure, the button cap 101 of the button 10 of the conventional keyboard 1 is higher than the spacer 13 by the support of the scissors connecting member 102 and the elastic member 103, and when the user presses the button cap 101 thereof, As described above, the scissor-type connecting element 102 is correspondingly stretched and oscillated, and the elastic element 103 is correspondingly deformed downward to trigger the button switch 124, and the corresponding button signal can be output. At this time, the button cap 101 is used by the user. Pressing the stress and lowering the height downward causes the button cap 101 to sink into the accommodating space 131 of the spacer 13; however, when the user stops pressing the button cap 101, the elastic member 103 is elastically restored. When the deformation is upward, and then the trigger button switch 124 is stopped, the button signal can be stopped. At this time, the button cap 101 is displaced upward by the deformation of the elastic member 103, and the scissors connector member 102 is also driven and returned by the button cap 101. The initial state is that the button cap 101 will eventually return to its position above the spacer 13.

然而,隨著現今社會追求電子裝置輕、薄、易於攜帶的薄型化設計趨勢下,習知鍵盤1會因該按鍵帽101具有一定高度而難以降低其整體高度,進而導致難以使整體體積減小,而造成產品笨重、難以輕薄化之缺失。因此,如何發展一種可改善上述習知技術缺失,可改善鍵盤及按鍵設計,進而達成輕薄之可攜式目的之可升降之鍵盤結構,實為目前迫切需要解決之問題。However, with the trend of today's society pursuing a thin design that is light, thin, and easy to carry, the conventional keyboard 1 is difficult to reduce its overall height due to the height of the button cap 101, which makes it difficult to reduce the overall volume. The product is cumbersome and difficult to lose weight. Therefore, how to develop a keyboard structure that can improve the above-mentioned conventional technology, improve the keyboard and button design, and achieve a portable and portable purpose is a problem that is urgently needed to be solved.

體現本案特徵與優點的一些典型實施例將在後段的說明中詳細敘述。應理解的是本案能夠在不同的態樣上具有各種的變化,其皆不脫離本案的範圍,且其中的說明及圖示在本質上係當作說明之用,而非架構於限制本案。Some exemplary embodiments embodying the features and advantages of the present invention are described in detail in the following description. It is to be understood that the present invention is capable of various modifications in various aspects, and is not to be construed as a limitation.

請參閱第3圖,其係為本案第一較佳實施例之鍵盤之升降作動示意圖。如圖所示,本案之可升降之鍵盤結構20係應用於可攜式電腦2中,例如:筆記型電腦、掌上型電子裝置或是其他可攜式電子裝置中,以本實施例為例,可攜式電腦2係可為但不限為筆記型電腦。於本實施例中,可攜式電腦2具有上蓋2a及底座2b,底座2b係可為但不限為一盒體結構,用以容設可升降之鍵盤結構20及其內部之電路板及電子零件等,上蓋2a則對應覆蓋於底座2b上,以保護底座2b之可升降之鍵盤結構20及其內部之電路板及電子零件,俾利於使用者便於攜帶及使用。其中,可升降之鍵盤結構20包含複數個按鍵21、21’、21”,然該複數個按鍵21、21’、21”之數量及配置方式係可依照實際施作情形而任施變化,並不以本案所示之實施例為限。Please refer to FIG. 3 , which is a schematic diagram of the lifting and lowering operation of the keyboard of the first preferred embodiment of the present invention. As shown in the figure, the keyboard structure 20 of the present invention can be used in a portable computer 2, such as a notebook computer, a palm-sized electronic device, or other portable electronic devices. The portable computer 2 series can be, but is not limited to, a notebook computer. In this embodiment, the portable computer 2 has an upper cover 2a and a base 2b. The base 2b can be, but is not limited to, a box structure for accommodating the keyboard structure 20 and the circuit board and the electronics therein. For the parts and the like, the upper cover 2a is correspondingly covered on the base 2b to protect the liftable keyboard structure 20 of the base 2b and the circuit board and electronic components therein, which is convenient for the user to carry and use. The keyboard structure 20 that can be raised and lowered includes a plurality of buttons 21, 21', 21", but the number and arrangement of the plurality of buttons 21, 21', 21" can be changed according to actual implementation conditions, and Not limited to the examples shown in this case.

於一些實施例中,底座2b內設置一感應器2b1,該感應器2b1係可為電磁感應器或是光學感應器,均不以此為限,用以感應上蓋2a是否接近並覆蓋於底座2b上,舉例來說,當該感應器2b1為電子感應器,例如:霍爾感應器,則在上蓋2a上亦具有對應的磁性元件2a1,如此一來,如第3圖所示,在底座2b上的感應器2b1則可感應上蓋2a上的磁性元件2a1之距離,當上蓋2a如(a)狀態所示,未覆蓋於底座2b上時,則由於上蓋2a的磁性元件2a1距離底座2b上的感應器2b1較遠,是以感應器2b1不會感應到磁性元件2a1,且不會產生相關訊號。然而,當上蓋2a於旋轉過程中,上蓋2a位於一特定角度時,此時磁性元件2a1與感應器2b1之間的距離達到一特定值,即感應器2b1感應到磁性元件2a1之存在,因而產生電磁訊號,觸發排氣閥座23(如第4A圖所示)之抽氣作動,進而使可升降之鍵盤結構20之複數個按鍵21、21’、21”向下位移而降低高度,而使上蓋2a可如(b)狀態所示,向下覆蓋於底座2b上,且由於可升降之鍵盤結構20之高度降低,進而可降低可攜式電腦2之整體厚度,使得可攜式電腦2更可達成輕、薄、便於攜帶之目的。In some embodiments, a sensor 2b1 is disposed in the base 2b, and the sensor 2b1 can be an electromagnetic sensor or an optical sensor, which is not limited thereto, and is used to sense whether the upper cover 2a is close to and covers the base 2b. For example, when the sensor 2b1 is an electronic sensor, for example, a Hall sensor, the corresponding magnetic element 2a1 is also provided on the upper cover 2a, and thus, as shown in FIG. 3, at the base 2b The upper sensor 2b1 can sense the distance of the magnetic element 2a1 on the upper cover 2a. When the upper cover 2a is not covered on the base 2b as shown in the state of (a), since the magnetic element 2a1 of the upper cover 2a is away from the base 2b The sensor 2b1 is far away, so that the sensor 2b1 does not sense the magnetic element 2a1 and does not generate a related signal. However, when the upper cover 2a is at a certain angle during the rotation, the distance between the magnetic element 2a1 and the inductor 2b1 reaches a certain value, that is, the sensor 2b1 senses the presence of the magnetic element 2a1, thereby generating The electromagnetic signal triggers the pumping action of the exhaust valve seat 23 (shown in FIG. 4A), thereby causing the plurality of buttons 21, 21', 21" of the liftable keyboard structure 20 to be displaced downwardly to lower the height, thereby The upper cover 2a can cover the base 2b downward as shown in the state of (b), and the height of the keyboard structure 20 can be lowered, thereby reducing the overall thickness of the portable computer 2, so that the portable computer 2 is more It can be light, thin and easy to carry.

One side of the inlet 230a communicates with the inlet port 221 of the membrane switch circuit layer 22, and the other side Then, it is connected to the inlet temporary storage chamber 230c, and one side of the outlet 230b is in communication with the exhaust port 222 of the membrane switch circuit layer 22, and the other side is connected to the outlet temporary storage chamber 230d, wherein the inlet temporary storage chamber 230c and the outlet The temporary storage chamber 230d is configured to temporarily store the gas, and the connecting passage 230e is connected between the inlet temporary storage chamber 230c and the outlet temporary storage chamber 230d for the gas to circulate.

於本實施例中,出口230b之端部可進一步增設一凸出而形成之凸部結構230f,例如可為但不限為圓柱結構,但不以此為限。以及,閥門片231更具有一閥孔231a,其中閥孔231a係與入口230a及入口暫存腔230c相對應。集氣板232具有第一貫穿孔232a及第二貫穿孔232b,其中第一貫穿孔232a及第二貫穿孔232b之一端係與排氣腔240相連通,另一端則分別與入口暫存腔230c及出口暫存腔230d相連通。以及,在鄰近於第一貫穿孔232處更進一步增設一凸部結構232c,例如可為但不限為一圓柱結構,且其係與閥門片231之閥孔231a對應設置。是以,當閥門片231與出口板230及集氣板232定位組裝時,係將其閥孔231a對應於集氣板232之凸部結構232c而對應設置,藉由此單一之閥孔231a之設計,以使氣體可因應其壓差而達到單向流動之目的。In this embodiment, the convex portion structure 230f may be formed by a protrusion, and may be, for example, but not limited to, a cylindrical structure, but is not limited thereto. And, the valve piece 231 further has a valve hole 231a, wherein the valve hole 231a corresponds to the inlet 230a and the inlet temporary cavity 230c. The gas collecting plate 232 has a first through hole 232a and a second through hole 232b, wherein one end of the first through hole 232a and the second through hole 232b is in communication with the exhaust chamber 240, and the other end is respectively connected to the inlet temporary cavity 230c. And the outlet temporary storage chamber 230d is in communication. Further, a protrusion structure 232c is further disposed adjacent to the first through hole 232, and may be, for example, but not limited to, a cylindrical structure, and is disposed corresponding to the valve hole 231a of the valve piece 231. Therefore, when the valve piece 231 is assembled and assembled with the outlet plate 230 and the gas collecting plate 232, the valve hole 231a is correspondingly disposed corresponding to the convex portion structure 232c of the gas collecting plate 232, whereby the single valve hole 231a is Designed so that the gas can reach one-way flow in response to its differential pressure.

以及,於本實施例中,每一排氣閥座23、23’、23”各具有一相互連通之排氣腔240、240’、240”,意即排氣閥座23之排氣腔240係與相鄰之排氣閥座23’之排氣腔240’相連通,排氣閥座23’ 之排氣腔240’則與相鄰之排氣閥座23及23”之排氣腔240、240”相連通,而另一排氣閥座23” 之排氣腔240”一端與相鄰之排氣閥座23’之排氣腔240’相連通,另一端則與另一泵浦裝置24相連通。然此僅說明及圖示僅用以示意本案之排氣閥座23、23’、23”與泵浦裝置24串接之方式,其設置及串接之方式係可依照實際施作情形而任施變化,並不以此為限。And, in this embodiment, each of the exhaust valve seats 23, 23', 23" has an exhaust chamber 240, 240', 240" that communicate with each other, that is, an exhaust chamber 240 of the exhaust valve seat 23. The exhaust chamber 240' of the adjacent exhaust valve seat 23' is in communication with the exhaust chamber 240' of the exhaust valve seat 23' and the exhaust chamber 240 of the adjacent exhaust valve seat 23 and 23" 240" is connected, and one end of the exhaust chamber 240" of the other exhaust valve seat 23" is in communication with the exhaust chamber 240' of the adjacent exhaust valve seat 23', and the other end is connected to another pumping device. 24 phases are connected. However, the description and illustration only show the manner in which the exhaust valve seats 23, 23', 23" of the present invention are connected in series with the pumping device 24. The arrangement and the manner of the series connection can be performed according to the actual application situation. Changes are not limited to this.

請同時參閱第4A圖及第4B圖,如第4A圖所示,當泵浦裝置24未作動時,氣體會由排氣腔240進入排氣閥座23內,並經由集氣板232之第一貫穿孔232b及第二貫穿孔232c進入入口暫存腔230c及出口暫存腔230d內,此時,由於氣體持續地自排氣腔240輸入,是以會產生壓差而致使閥門片231向上推動,並開啟閥門片231上之閥孔231a,而可使氣體自閥孔231a處流入入口暫存腔230c中,再由入口230a經薄膜開關電路層22之進氣口221傳送至彈性元件212之腔體212a之內,故可使彈性元件212維持原本之型態,並使剪刀式元件211支撐按鍵帽210,以維持按鍵21之高度,供使用者按壓使用。此時,由於閥門片231係向上形變,是以於閥門片231之另一側則會抵頂於出口板230之凸部結構230f上,進而封閉出口230b,即排氣閥座23內之氣體無法由出口230b而輸送至薄膜開關電路層22之排氣口222,故無氣體排出。Please refer to FIG. 4A and FIG. 4B at the same time. As shown in FIG. 4A, when the pumping device 24 is not actuated, the gas will enter the exhaust valve seat 23 from the exhaust chamber 240 and pass through the gas collecting plate 232. The continuous through hole 232b and the second through hole 232c enter the inlet temporary storage cavity 230c and the outlet temporary storage cavity 230d. At this time, since the gas is continuously input from the exhaust cavity 240, a pressure difference is generated to cause the valve piece 231 to be upward. Pushing and opening the valve hole 231a on the valve piece 231, the gas can flow from the valve hole 231a into the inlet temporary storage chamber 230c, and then the inlet 230a is transmitted to the elastic member 212 through the air inlet 221 of the membrane switch circuit layer 22. Within the cavity 212a, the elastic member 212 can be maintained in its original configuration, and the scissors member 211 can support the button cap 210 to maintain the height of the button 21 for the user to press. At this time, since the valve piece 231 is deformed upward, the other side of the valve piece 231 abuts against the convex portion structure 230f of the outlet plate 230, thereby closing the outlet 230b, that is, the gas in the exhaust valve seat 23. It cannot be transported to the exhaust port 222 of the membrane switch circuit layer 22 by the outlet 230b, so that no gas is discharged.

然而,當泵浦裝置24接收感應器2b1傳送之電磁訊號後,則泵浦裝置24係可因應該電磁訊號而啟動作動,進而對排氣閥座23進行抽氣,此時排氣閥座23內部的氣體會由相連通之排氣腔240而傳送至泵浦裝置24,進而產生壓差,而導致氣體由集氣板232之第一貫穿孔232a及第二貫穿孔232b流入集氣腔室232a內,並使閥門片231隨之向下作動,是以,閥門片231會向下抵頂於凸部結構232d,並使閥孔231c封閉,即入口暫存腔230c內的氣體不會向下逆流;同時,另一側之閥門片231亦會向下作動時,進而可使出口板230之出口230b與出口暫存腔230d相連通,並可同時經由薄膜開關電路層22之排氣口222而與外界相連通,故氣體會由出口板230之入口230a流入入口暫存腔230c內,再經由連通道230e而流至出口暫存腔230d,最後由出口板230之出口230b經排氣口222而排出可升降之鍵盤結構20之外。However, when the pumping device 24 receives the electromagnetic signal transmitted by the sensor 2b1, the pumping device 24 can actuate according to the electromagnetic signal, thereby pumping the exhaust valve seat 23, and at this time, the exhaust valve seat 23 The internal gas is sent to the pumping device 24 by the exhaust chamber 240 that communicates with each other, thereby generating a pressure difference, which causes the gas to flow from the first through hole 232a and the second through hole 232b of the gas collecting plate 232 into the gas collecting chamber. 232a, and the valve piece 231 is actuated downwards, so that the valve piece 231 will abut against the convex structure 232d and the valve hole 231c is closed, that is, the gas in the inlet temporary cavity 230c will not be directed At the same time, when the valve piece 231 on the other side is also actuated downward, the outlet 230b of the outlet plate 230 can be connected to the outlet temporary storage chamber 230d, and can simultaneously pass through the exhaust port of the membrane switch circuit layer 22. 222 is connected to the outside, so that the gas flows into the inlet temporary storage chamber 230c from the inlet 230a of the outlet plate 230, flows to the outlet temporary storage chamber 230d via the connecting passage 230e, and is finally exhausted by the outlet 230b of the outlet plate 230. The port 222 is discharged from the keyboard structure 20 that can be lifted and lowered.

當然,前述之實施說明係採以按鍵21、薄膜開關電路層22、及其對應之排氣閥座23為例進行詳細說明,然當泵浦裝置24係可因應該電磁訊號而作動,其係同時對複數個排氣閥座23、23’、23”進行抽氣,並使複數個排氣閥座23、23’、23”內部的氣體會由相連通之排氣腔240、240’、240”而傳送至泵浦裝置24,進而致使複數個排氣閥座23、23’、23”同時進行抽氣作動,且由於每一排氣閥座23、23’、23”均同時透過泵浦裝置24之作動以進行抽氣,是以每一按鍵21、21’、21”均會因該泵浦裝置24之抽氣作動,使每一彈性元件212之腔體212a內之氣體被抽出,並產生壓縮形變,進而使每一按鍵21之按鍵帽210向下位移h之距離,以如第4B圖所示,同時降低每一按鍵21、21’、21之高度,並降低可升降之鍵盤結構20之整體厚度,使得可攜式電腦2更可達成輕、薄、便於攜帶之目的。Of course, the foregoing implementation description uses the button 21, the membrane switch circuit layer 22, and the corresponding exhaust valve seat 23 as an example for detailed description. However, when the pump device 24 is activated by the electromagnetic signal, the system is activated. At the same time, a plurality of exhaust valve seats 23, 23', 23" are pumped, and the gas inside the plurality of exhaust valve seats 23, 23', 23" is connected to the exhaust chambers 240, 240', 240" is transmitted to the pumping device 24, thereby causing the plurality of exhaust valve seats 23, 23', 23" to simultaneously perform the pumping operation, and since each of the exhaust valve seats 23, 23', 23" simultaneously transmits the pump The pump device 24 is actuated to perform pumping, so that each button 21, 21', 21" is actuated by the pumping device 24, so that the gas in the cavity 212a of each elastic member 212 is extracted. And generating a compression deformation, so that the button cap 210 of each button 21 is displaced downward by a distance h, as shown in FIG. 4B, while reducing the height of each button 21, 21', 21, and lowering the liftable The overall thickness of the keyboard structure 20 makes the portable computer 2 more light, thin and portable.

綜上所述,本案所提供之可升降之鍵盤結構係應用於可攜式電腦中,且搭配其底座之感應器而作動,該可升降之鍵盤結構包括複數個按鍵、薄膜開關電路層、複數個排氣閥座及泵浦裝置等結構,當感應器感應到上蓋接近時,則觸發訊號並傳遞至泵浦裝置,透過泵浦裝置之抽氣作動,以帶動排氣閥座進行抽氣作動,以對按鍵內之彈性元件進行抽氣,使彈性元件產生形變而向下壓縮,進而使按鍵之按鍵帽向下位移,進而可自動地降低按鍵之高度,以降低可升降之鍵盤結構之整體厚度,俾使可攜式電腦於上蓋闔起關閉時,更能降低整體厚度,而達到輕薄化設計之目的;因此,本案可升降之鍵盤結構可自動偵測上蓋接近時而使可升降之鍵盤結構下降高度,更可使整體體積減小及薄型化,以達到輕便舒適之可攜式目的,極具產業利用價值,爰依法提出申請。In summary, the keyboard structure that can be raised and lowered in the present invention is applied to a portable computer and is actuated by a sensor of the base thereof. The keyboard structure of the liftable keyboard includes a plurality of buttons, a membrane switch circuit layer, and a plurality of The exhaust valve seat and the pumping device and the like, when the sensor senses that the upper cover is close, the signal is triggered and transmitted to the pumping device, and the pumping device is driven by the pumping device to drive the exhaust valve seat to perform the pumping operation. The air member in the button is pumped to deform the elastic member and compress downward, thereby causing the button cap of the button to be displaced downward, thereby automatically reducing the height of the button to reduce the overall structure of the keyboard that can be lifted and lowered. The thickness allows the portable computer to reduce the overall thickness when the upper cover is closed, thereby achieving the purpose of slimming design; therefore, the keyboard structure of the present invention can automatically detect the upper cover and the keyboard that can be lifted and lowered. The height of the structure is reduced, and the overall volume can be reduced and thinned, so as to achieve the portable and portable purpose, which is of great industrial value, and is applied according to law.
