Description
本發明關於一種鍵盤，尤指一種具有使部分按鍵下降之功能的鍵盤。The present invention relates to a keyboard, and more particularly to a keyboard having a function of lowering a portion of a button.
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。In terms of current personal computer usage habits, the keyboard is one of the indispensable input devices for entering text, symbols or numbers. Moreover, the consumer electronics products that are in contact with everyday life or the large-scale processing equipment used in the industry need to have a button structure as an input device to operate the above-mentioned electronic products and processing equipment.
一般傳統鍵盤係採用將剪刀腳支撐裝置與彈性件之組裝結構設置於鍵帽與底板之間的按壓設計，藉此，當鍵帽被使用者按壓後，彈性件提供彈性回復力至鍵帽，以驅動鍵帽隨著剪刀腳支撐裝置之機構作動回復至按壓前之位置。然而，由於上述剪刀腳支撐裝置所採用的剪刀腳支撐件交叉樞接設計係會導致按鍵需要較大的高度空間，故當筆記型電腦之上蓋與下殼體收合時，為了避免設置於下殼體上之鍵帽傷及設置於上蓋之顯示螢幕，上蓋與下殼體之間常保留有餘隙以容置鍵帽，如此即會限制筆記型電腦的外觀尺寸設計，而不利於筆記型電腦之薄型化設計。Generally, the conventional keyboard adopts a pressing design in which the assembly structure of the scissor foot supporting device and the elastic member is disposed between the key cap and the bottom plate, thereby, when the key cap is pressed by the user, the elastic member provides elastic restoring force to the key cap. The drive key cap is returned to the position before pressing with the mechanism of the scissor foot support device. However, since the cross-pivot design of the scissor-foot support member used in the scissor-foot supporting device causes a large height space of the button, when the upper cover of the notebook computer is folded with the lower case, in order to avoid being placed under The keycap on the casing injures the display screen disposed on the upper cover, and the gap between the upper cover and the lower casing often retains the keycap, which limits the appearance of the notebook computer, and is not advantageous for the notebook computer. Thin design.
除此之外，為了符合各種多元的輸入應用，鍵盤上的所有按鍵通常須按照特定鍵位分佈方式排列並且在未按壓時能夠維持在同一高度以便使用者進行相關按壓輸入操作，但隨著電競產業的蓬勃發展，再加上在遊戲過程中，使用者往往僅需對某些特定鍵位功能的按鍵（如W、S、A、D鍵）進行頻繁且快速的按壓操作，因此，如何有效地避免使用者誤按壓以利於使用者進行高精準度的按鍵輸入操作係為目前鍵盤在按鍵設計上之主要課題之一。In addition, in order to comply with a variety of multi-input applications, all the keys on the keyboard usually have to be arranged according to a specific key distribution and can be maintained at the same height when not pressed for the user to perform the relevant pressing input operation, but with the electricity The booming development of the competitive industry, coupled with the game, the user often only needs to press the keys of certain key functions (such as W, S, A, D) frequently and quickly, so how Effectively avoiding the user's accidental pressing to facilitate the user to perform high-precision key input operation is one of the main topics of the current keyboard design.

The thin design is designed to effectively solve the problems of the keycap injury and display screen mentioned in the prior art. In addition, in the application scenario where the user only needs to perform frequent and fast pressing operations on the second button, the first keycap can be lowered when the lower bottom plate slides from the unfolded position to the folded position relative to the upper bottom plate. To the folding height, but the second keycap is still maintained at the unfolded height, thereby generating a partial drop function of the button to assist the user to accurately and frequently press the second button without pressing the key cap. The first button greatly enhances the ease of operation of the keyboard and the precision of the button press. It should be noted that, since the present invention adopts the design that the first button does not trigger when the first keycap is pressed, even if the user accidentally presses the first button with the height of the keycap lowered, The present invention can still reliably avoid the problem of user's accidental pressing.

由第1圖、第2圖、第4圖，以及第7圖可知，第一按鍵16係設置於上底板12上，第一按鍵16包含第一鍵帽24以及第一支撐裝置26。第一支撐裝置26係設置於上底板12以及第一鍵帽24之間且可較佳地採用常見應用在鍵盤按鍵上的剪刀腳支撐機構設計（但不受此限，其亦可採用其他常見按鍵升降支撐設計，如磁吸按鍵設計等），在此實施例中，第一支撐裝置26可包含第一支撐件28以及第二支撐件30，第一支撐件28以及第二支撐件30係可活動地連接第一鍵帽24以及上底板12且彼此交叉樞接，以使第一鍵帽24可隨著第一支撐件28以及第二支撐件30之交叉樞轉相對於上底板12上下移動。在此實施例中，第一支撐件28對應卡勾15之位置可具有抵接面結構29，抵接面結構29係可較佳地為斜面結構且以厚度漸減之方式延伸形成（但不以此為限，舉例來說，在另一實施例中，本發明可採用抵接面結構為曲面結構之設計），藉此，卡勾15係可隨著下底板14之滑動而沿著抵接面結構29滑動，以驅動第一鍵帽24在下底板14相對於上底板12滑動的過程中下降至收合高度。As can be seen from FIGS. 1 , 2 , 4 , and 7 , the first button 16 is disposed on the upper base plate 12 , and the first button 16 includes the first key cap 24 and the first support device 26 . The first supporting device 26 is disposed between the upper bottom plate 12 and the first keycap 24 and can preferably be designed with a scissor foot supporting mechanism commonly used on keyboard keys (but not limited thereto, and other common The button support design, such as a magnetic button design, etc., in this embodiment, the first support device 26 can include a first support member 28 and a second support member 30, the first support member 28 and the second support member 30 The first keycap 24 and the upper bottom plate 12 are movably connected and pivotally connected to each other such that the first keycap 24 can pivot relative to the upper bottom plate 12 along with the intersection of the first support member 28 and the second support member 30. mobile. In this embodiment, the first support member 28 may have an abutting surface structure 29 corresponding to the position of the hook 15. The abutting surface structure 29 may preferably be a beveled structure and extend in a decreasing thickness (but not For example, in another embodiment, the present invention can adopt a design in which the abutting surface structure is a curved surface structure, whereby the hook 15 can be abutted along with the sliding of the lower bottom plate 14 The face structure 29 slides to drive the first keycap 24 to descend to the take-up height during sliding of the lower bottom plate 14 relative to the upper bottom plate 12.
在第二按鍵18之設計方面，如第1圖、第3圖、第5圖以及第7圖所示，第二按鍵18係設置於上底板12上，第二按鍵18包含第二鍵帽32以及第二支撐裝置34，第二支撐裝置34係設置於上底板12以及第二鍵帽32之間且較佳地採用剪刀腳支撐設計（其相關描述可參照上述說明類推，於此不再贅述）以可活動地連接第二鍵帽32以及上底板12，使得第二鍵帽32可經由第二支撐裝置34相對於上底板12上下移動。In the design of the second button 18, as shown in FIG. 1, FIG. 3, FIG. 5, and FIG. 7, the second button 18 is disposed on the upper bottom plate 12, and the second button 18 includes the second key cap 32. And a second supporting device 34, the second supporting device 34 is disposed between the upper bottom plate 12 and the second keycap 32 and preferably adopts a scissor-foot supporting design (for the related description, reference may be made to the above description, and details are not described herein again. The second keycap 32 and the upper bottom plate 12 are movably coupled such that the second keycap 32 is movable up and down relative to the upper base plate 12 via the second support device 34.
需注意的是，在此實施例中，第一按鍵16以及第二按鍵18係可較佳地採用彈性復位設計以用來提供彈性力驅動第一鍵帽24以及第二鍵帽32回位，舉例來說，如第2圖以及第7圖所示，第一按鍵16可另包含底座36、上蓋38、套筒件40，以及彈性件42，底座36係設置於上底板12上且穿設於第一支撐件28以及第二支撐件30中，上蓋38係設置於底座36上，套筒件40穿過上蓋38以連接於第一鍵帽24，彈性件42（如彈簧，但不以此為限）分別抵接套筒件40以及底座36以使套筒件40朝遠離底座36之方向運動。藉此，當按壓第一鍵帽24的外力被釋放時，彈性件42係可經由套筒件40驅動第一鍵帽24向上移動，從而產生鍵帽自動回位的功效，以便使用者進行後續按壓操作。It should be noted that, in this embodiment, the first button 16 and the second button 18 are preferably resiliently reset to provide an elastic force to drive the first keycap 24 and the second keycap 32 to return. For example, as shown in FIG. 2 and FIG. 7 , the first button 16 may further include a base 36 , an upper cover 38 , a sleeve member 40 , and an elastic member 42 .

Thereby, when the external force pressing the first keycap 24 is released, the elastic member 42 can drive the first keycap 24 to move upward via the sleeve member 40, thereby generating the function of automatically returning the keycap for the user to follow. Press the operation.
至於在第一按鍵16以及第二按鍵18之觸發設計方面，由第4圖、第5圖以及第7圖可知，第一電路板20係貼附於下底板14且具有第一光學發射器44以及第一光學接收器46，第一光學發射器44與第一光學接收器46彼此相對且往光學接收器46發射光線，第二支撐件30往第一電路板20向下延伸形成有第一遮斷板48。第二電路板22係貼附於上底板12且具有第二光學發射器50以及第二光學接收器52，第二光學發射器50與第二光學接收器52彼此相對且往第二光學接收器52發射光線，第二支撐裝置34往第二電路板22向下延伸形成有第二遮斷板54。在此實施例中，第一光學接收器46以及第二光學接收器52係可較佳地為一紅外線接收裝置且第一光學發射器44以及第二光學發射器50係可較佳地為一紅外線發射裝置，但不以此為限。As for the trigger design of the first button 16 and the second button 18, as can be seen from FIGS. 4, 5, and 7, the first circuit board 20 is attached to the lower chassis 14 and has the first optical emitter 44. And the first optical receiver 46, the first optical transmitter 44 and the first optical receiver 46 are opposite to each other and emit light to the optical receiver 46, and the second support member 30 extends downwardly toward the first circuit board 20 to form a first The shutter 48. The second circuit board 22 is attached to the upper substrate 12 and has a second optical emitter 50 and a second optical receiver 52. The second optical emitter 50 and the second optical receiver 52 are opposite each other and to the second optical receiver. 52 emits light, and the second supporting device 34 extends downwardly toward the second circuit board 22 to form a second blocking plate 54. In this embodiment, the first optical receiver 46 and the second optical receiver 52 are preferably an infrared receiving device, and the first optical transmitter 44 and the second optical transmitter 50 are preferably one. Infrared emitting device, but not limited to this.
透過上述設計，當下底板14位於未收合位置且第一鍵帽24未被按壓時，第一光學發射器44所發射之光線係可入射至第一光學接收器46，從而建立第一光學發射器44與第一光學接收器46之間的光路傳輸。接下來，在第一鍵帽24被外力按壓的過程中，第一支撐件28以及第二支撐件30隨著第一鍵帽24之向下移動而相對向下交叉樞轉，使得第一遮斷板48可隨著第一支撐件28向下移動以阻斷上述第一光學發射器44與第一光學接收器46之間的光路傳輸，藉以產生相對應之第一輸入訊號傳送至第一電路板20，從而使第一按鍵16可據以執行使用者所欲輸入之功能。Through the above design, when the lower bottom plate 14 is in the unfolded position and the first keycap 24 is not pressed, the light emitted by the first optical emitter 44 can be incident on the first optical receiver 46, thereby establishing the first optical emission. The optical path between the device 44 and the first optical receiver 46 is transmitted. Next, during the pressing of the first keycap 24 by an external force, the first support member 28 and the second support member 30 pivot relative to the downward movement as the first keycap 24 moves downward, so that the first cover The breaking plate 48 can move downward along the first support member 28 to block the optical path between the first optical transmitter 44 and the first optical receiver 46, thereby generating a corresponding first input signal to be transmitted to the first The circuit board 20 is such that the first button 16 can perform the function that the user desires to input.
另一方面，當第二鍵帽32未被按壓時，第二光學發射器50所發射之光線係可入射至第二光學接收器52，從而建立第二光學發射器50與第二光學接收器52之間的光路傳輸。接下來，在第二鍵帽32被外力按壓的過程中，第二遮斷板54可隨著第二支撐裝置34向下移動以阻斷上述第二光學發射器50與第二光學接收器52之間的光路傳輸，藉以產生相對應之第二輸入訊號傳送至第二電路板22，從而使第二按鍵18可據以執行使用者所欲輸入之功能。On the other hand, when the second keycap 32 is not pressed, the light emitted by the second optical emitter 50 can be incident on the second optical receiver 52, thereby establishing the second optical emitter 50 and the second optical receiver. Optical path between 52. Next, during the pressing of the second keycap 32 by an external force, the second shutter 54 may move downward with the second supporting device 34 to block the second optical emitter 50 and the second optical receiver 52 described above. The optical path between the two is transmitted to the second circuit board 22, so that the second button 18 can perform the function that the user desires to input.
以下係針對鍵盤10之按鍵高度調整操作進行詳細說明，由第1圖至第7圖可知，當第一鍵帽24未被按壓且下底板14相對於上底板12滑動至如第4圖所示之收合位置時，卡勾15係可沿著抵接面結構29滑動（如第6圖所示）而下壓第一支撐件28，以驅動第一鍵帽24克服彈性件42之彈力且下降至如第7圖所示之收合高度，在此過程中，由第3圖以及第7圖可知，由於下底板14對應第二按鍵18之位置不具有卡勾15，使得第二按鍵18不會隨著上述下底板14之滑動而被下壓，因此，第二鍵帽32係可維持在如第7圖所示之未收合高度。The following is a detailed description of the key height adjustment operation of the keyboard 10. As can be seen from FIGS. 1 to 7, when the first keycap 24 is not pressed and the lower bottom plate 14 is slid relative to the upper bottom plate 12 as shown in FIG. In the collapsed position, the hook 15 is slidable along the abutment surface structure 29 (as shown in FIG. 6) and the first support member 28 is depressed to drive the first keycap 24 against the elastic force of the elastic member 42 and Descending to the folding height as shown in FIG. 7 , in the process, as can be seen from FIG. 3 and FIG. 7 , since the lower bottom plate 14 does not have the hook 15 corresponding to the position of the second button 18 , the second button 18 is caused. It is not pressed down as the lower bottom plate 14 slides. Therefore, the second keycap 32 can be maintained at the unfolded height as shown in Fig. 7.
透過上述設計，當配置有第一按鍵16以及第二按鍵18之鍵盤10應用於一般具有由上蓋與下殼體組成之開合機構的可攜式電子裝置上（例如筆記型電腦）時，鍵盤10即可驅動下底板14隨可攜式電子裝置之上蓋相對下殼體閉合而相對於上底板12滑動，使得第一鍵帽24係可隨之下降至如第7圖所示之收合高度，藉以達到鍵盤10可隨著可攜式電子裝置之閉合而降低鍵帽高度之功效，換句話說，當下底板14相對於上底板12滑動以壓迫第一按鍵16之第一支撐裝置26時，第一按鍵16係可處於鍵帽高度下降的狀態以進一步地縮減整體高度，從而有利於可攜式電子裝置之薄型化設計並且有效地解決先前技術所提到的鍵帽傷及顯示螢幕的問題。除此之外，在使用者僅需要針對第二按鍵18進行頻繁快速之按壓操作的應用情境下，由上述可知，當下底板14相對於上底板12從未收合位置滑動至收合位置時，第一鍵帽24係可下降至收合高度但第二鍵帽32仍然維持在未收合高度（如第7圖所示），藉以產生按鍵局部下降功效而協助使用者可精準地對第二按鍵18進行頻繁快速之按壓操作而不會誤按壓到鍵帽高度下降的第一按鍵16，從而大大地提升鍵盤10之操作便利性與按鍵按壓精準度。Through the above design, when the keyboard 10 configured with the first button 16 and the second button 18 is applied to a portable electronic device (such as a notebook computer) generally having an opening and closing mechanism composed of an upper cover and a lower case, the keyboard 10 can drive the lower bottom plate 14 to slide relative to the upper bottom plate 12 with the upper cover of the portable electronic device closed relative to the lower casing, so that the first keycap 24 can be lowered to the folding height as shown in FIG. In order to achieve the effect that the keyboard 10 can lower the height of the keycap with the closure of the portable electronic device, in other words, when the lower bottom plate 14 slides relative to the upper bottom plate 12 to press the first supporting device 26 of the first button 16, The first button 16 can be in a state in which the height of the key cap is lowered to further reduce the overall height, thereby facilitating the thin design of the portable electronic device and effectively solving the problem of the keycap injury and the display screen mentioned in the prior art. . In addition, in the application scenario where the user only needs to perform frequent and fast pressing operations on the second button 18, it can be seen from the above that when the lower bottom plate 14 slides from the unfolded position to the folded position with respect to the upper bottom plate 12, The first keycap 24 can be lowered to the folding height but the second keycap 32 is still maintained at the unfolded height (as shown in FIG. 7), thereby generating a partial drop effect of the button to assist the user in accurately targeting the second The button 18 performs a frequent quick pressing operation without accidentally pressing the first button 16 whose key cap height is lowered, thereby greatly improving the operational convenience of the keyboard 10 and the button pressing accuracy.
需注意的是，由第4圖以及第7圖可知，在上述下底板14相對於上底板12滑動至收合位置的過程中，第一電路板20隨著下底板14滑動至使第一光學發射器44以及第一光學接收器46與第一遮斷板48錯位之位置而無法實現上述光學觸發功效（也就是說，在此情況下，第一遮斷板48於第一鍵帽24被按壓時無法阻斷第一光學發射器44與第一光學接收器46之間的光路傳輸），如此一來，即使在使用者不慎按壓到鍵帽高度下降之第一按鍵16的情況下，第一按鍵16仍然不會被觸發，從而確實地避免使用者誤按壓的問題。It should be noted that, as can be seen from FIG. 4 and FIG. 7 , in the process of sliding the lower bottom plate 14 relative to the upper bottom plate 12 to the folding position, the first circuit board 20 slides along with the lower bottom plate 14 to make the first optical The position where the transmitter 44 and the first optical receiver 46 are misaligned with the first shutter 48 cannot achieve the above optical triggering effect (that is, in this case, the first shutter 48 is placed on the first keycap 24 The optical path between the first optical transmitter 44 and the first optical receiver 46 cannot be blocked when pressed, so that even if the user accidentally presses the first button 16 whose height of the key cap is lowered, The first button 16 is still not triggered, thereby reliably avoiding the problem of the user accidentally pressing.
值得一提的是，本發明之按鍵觸發設計係可不限於上述實施例所提及之光學觸發設計，其亦可改採用機械式觸發設計，舉例來說，請參閱第8圖、第9圖、第10圖，以及第11圖，第8圖為根據本發明另一實施例所提出之鍵盤100之部分放大示意圖，第9圖為第8圖之第一按鍵104之內部結構示意圖，第10圖為第8圖之第一按鍵104以及第二按鍵106於第一鍵帽24下降至收合高度時之立體示意圖，第11圖為第10圖之第一按鍵104沿著剖面線C-C之剖面示意圖，其中為了清楚地顯示第一按鍵104以及第二按鍵106的內部結構，第一鍵帽24以及第二鍵帽32於第8圖與第10圖中係以虛線簡示且於第9圖中省略下底板14、第一鍵帽24、第一支撐裝置26、上蓋112、彈性件116之繪示，另外，在此實施例中所提及之元件與上述實施例所提及之元件具有相同編號者，代表其具有相似之結構或功能，其相關描述於此不再贅述。如第8圖至第11圖所示，鍵盤100包含上底板12、下底板14、電路板102、第一按鍵104以及第二按鍵106，電路板102、第一按鍵104以及第二按鍵106係設置於上底板12上，其中第一按鍵104係可視為使用者在某些特定使用情境下（例如使用鍵盤100進行射擊遊戲之輸入操作時）較不會使用到的按鍵（如Q、E鍵等）而具有鍵帽收合功能，第二按鍵106則是會頻繁按壓到的按鍵（如W、S、A、D鍵等）而不具有鍵帽收合功能，至於針對第一按鍵104以及第二按鍵106之數量與排列的相關配置，其端視鍵盤100之實際應用而定，並不以第8圖為限。It should be noted that the key trigger design of the present invention may not be limited to the optical trigger design mentioned in the above embodiments, and the mechanical trigger design may also be used. For example, please refer to FIG. 8 and FIG. 10, and FIG. 11, FIG. 8 is a partially enlarged schematic view of a keyboard 100 according to another embodiment of the present invention, and FIG. 9 is a schematic diagram showing the internal structure of the first button 104 of FIG. FIG. 11 is a schematic cross-sectional view of the first button 104 of FIG. 10 along the section line CC when the first button 104 and the second button 106 are lowered to the folding height of the first button cap 24. In order to clearly display the internal structure of the first button 104 and the second button 106, the first keycap 24 and the second keycap 32 are shown in dotted lines in FIGS. 8 and 10 and are in FIG. The bottom plate 14, the first keycap 24, the first supporting device 26, the upper cover 112, and the elastic member 116 are omitted, and the components mentioned in this embodiment are the same as those mentioned in the above embodiments. Numbered, representing a similar structure or function, related Said omitted herein. As shown in FIGS. 8 to 11, the keyboard 100 includes an upper substrate 12, a lower substrate 14, a circuit board 102, a first button 104, and a second button 106. The circuit board 102, the first button 104, and the second button 106 are provided. It is disposed on the upper bottom plate 12, wherein the first button 104 can be regarded as a button that the user does not use when in certain specific use situations (for example, when the input operation of the shooting game is performed using the keyboard 100) (such as Q, E keys). And having a keycap folding function, the second button 106 is a button that is frequently pressed (such as W, S, A, D keys, etc.) without a keycap folding function, as for the first button 104 and The number of the second buttons 106 and the arrangement of the arrangement are determined depending on the actual application of the keyboard 100, and are not limited to the eighth figure.
更詳細地說，第一按鍵104包含第一鍵帽24、第一支撐裝置26，以及第一機械軸觸發開關108，第一機械軸觸發開關108係可採用常見之機械式按鍵觸發設計，舉例來說，如第8圖、第9圖，以及第11圖所示，第一機械軸觸發開關108可包含底座110、上蓋112、套筒件114、彈性件116、觸發彈臂118，以及觸發接點120，底座110係設置於上底板12上，上蓋112係設置於底座110上，套筒件114具有凸肋122且穿過上蓋112以連接於第一鍵帽24，彈性件116（如彈簧，但不受此限）係分別抵接套筒件114以及底座110以使套筒件114朝遠離底座110方向運動，觸發彈臂118係設置於底座110內，觸發接點120係與觸發彈臂118彼此相對，在此實施例中，觸發彈臂118與觸發接點120係可較佳地沿著底座110平面延伸設置（如第9圖所示，但不受此限），藉以進一步地縮減第一按鍵104之整體結構高度。至於在第二按鍵106之設計方面，第二按鍵106包含第二鍵帽32、第二支撐裝置34，以及第二機械軸觸發開關124，為簡化說明，針對第二機械軸觸發開關124之機械式按鍵觸發設計的相關描述係可參照上述針對第一機械軸觸發開關108之說明類推，於此不再贅述。In more detail, the first button 104 includes a first keycap 24, a first support device 26, and a first mechanical shaft trigger switch 108, and the first mechanical shaft trigger switch 108 can adopt a common mechanical button trigger design, for example. As shown in FIG. 8 , FIG. 9 , and FIG. 11 , the first mechanical shaft trigger switch 108 may include a base 110 , an upper cover 112 , a sleeve member 114 , an elastic member 116 , a triggering arm 118 , and a trigger The base 110 is disposed on the upper base plate 12, and the upper cover 112 is disposed on the base 110. The sleeve member 114 has a rib 122 and passes through the upper cover 112 to be coupled to the first keycap 24, and the elastic member 116 (such as The springs, but not limited thereto, respectively abut the sleeve member 114 and the base 110 to move the sleeve member 114 away from the base 110. The triggering arm 118 is disposed in the base 110, and the triggering contact 120 is triggered. The elastic arms 118 are opposite to each other. In this embodiment, the triggering arm 118 and the triggering contact 120 are preferably extended along the plane of the base 110 (as shown in FIG. 9 but not limited thereto), thereby further The overall structural height of the first button 104 is reduced. As for the design of the second button 106, the second button 106 includes a second keycap 32, a second support device 34, and a second mechanical shaft trigger switch 124. For simplicity of explanation, the mechanism for triggering the switch 124 for the second mechanical shaft For a description of the key trigger design, reference may be made to the above description of the first mechanical axis trigger switch 108, and details are not described herein.
透過上述設計，當第一鍵帽24未被按壓時，凸肋122偏壓觸發彈臂118撓曲變形，使觸發彈臂118與觸發接點120分離；當第一鍵帽24被外力按壓至如第11圖所示之位置時，觸發彈臂118改移動到與凸肋122錯開之位置，在此過程中，觸發彈臂118變形量減少，從而使觸發彈臂118抵接導通觸發接點120而產生相對應之第一輸入訊號傳送至電路板102，從而使鍵盤100可據以執行使用者所欲輸入之功能。另一方面，當上述外力消失時，彈性件116驅動套筒件114向上移動，以使第一鍵帽24回位且觸發彈臂118移動回被凸肋122偏壓之位置而與觸發接點120分離（如第9圖所示），進而產生第一鍵帽24可自動回位以供使用者再次按壓的功效。另一方面，相似地，當第二鍵帽32被外力按壓時，第二機械軸觸發開關124被觸發以產生相對應之第二觸發訊號至電路板102，從而使鍵盤100可據以執行使用者所欲輸入之功能。Through the above design, when the first keycap 24 is not pressed, the rib 122 biases to trigger the flexural deformation of the elastic arm 118, so that the triggering elastic arm 118 is separated from the triggering contact 120; when the first keycap 24 is pressed by an external force to When the position shown in FIG. 11 is used, the triggering arm 118 is moved to a position shifted from the rib 122. During this process, the amount of deformation of the triggering arm 118 is reduced, so that the triggering arm 118 abuts the conduction triggering contact. 120, a corresponding first input signal is transmitted to the circuit board 102, so that the keyboard 100 can perform the function that the user desires to input. On the other hand, when the external force disappears, the elastic member 116 drives the sleeve member 114 to move upward to return the first keycap 24 and trigger the elastic arm 118 to move back to the position biased by the rib 122 to trigger the contact. 120 separation (as shown in Figure 9), in turn, produces the effect that the first keycap 24 can be automatically returned for the user to press again. On the other hand, similarly, when the second keycap 32 is pressed by an external force, the second mechanical shaft trigger switch 124 is triggered to generate a corresponding second trigger signal to the circuit board 102, thereby enabling the keyboard 100 to perform the use. The function that you want to enter.
以下係針對鍵盤100之按鍵高度調整操作進行詳細說明，由第8圖、第10圖，以及第11圖可知，當第一鍵帽24未被按壓且下底板14相對於上底板12滑動至如第10圖所示之收合位置時，卡勾15係可沿著抵接面結構29滑動而下壓第一支撐件28，以驅動第一鍵帽24克服彈性件116之彈力且下降至如第10圖所示之收合高度，在此過程中，由於下底板14對應第二按鍵106之位置不具有卡勾15，使得第二按鍵106不會隨著上述下底板14之滑動而被下壓，因此，第二鍵帽32係可維持在如第10圖所示之未收合高度。The following is a detailed description of the key height adjustment operation of the keyboard 100. As can be seen from FIG. 8, FIG. 10, and FIG. 11, when the first keycap 24 is not pressed and the lower bottom plate 14 slides relative to the upper bottom plate 12, as shown in FIG. In the folded position shown in FIG. 10, the hook 15 is slidable along the abutting surface structure 29 to press down the first support member 28 to drive the first keycap 24 against the elastic force of the elastic member 116 and descend to The folding height shown in FIG. 10 is that, in the process, since the lower bottom plate 14 does not have the hook 15 corresponding to the position of the second button 106, the second button 106 does not fall under the sliding of the lower bottom plate 14 The pressure, therefore, the second keycap 32 can be maintained at the unfolded height as shown in FIG.
透過上述設計，當配置有第一按鍵104以及第二按鍵106之鍵盤100應用於一般具有由上蓋與下殼體組成之開合機構的可攜式電子裝置上（例如筆記型電腦）時，鍵盤100即可驅動下底板14隨可攜式電子裝置之上蓋相對下殼體閉合而相對於上底板12滑動，使得第一鍵帽24係可隨之下降至如第10圖所示之收合高度，從而有利於可攜式電子裝置之薄型化設計並且有效地解決先前技術所提到的鍵帽傷及顯示螢幕的問題。除此之外，在使用者僅需要針對第二按鍵106進行頻繁快速之按壓操作的應用情境下，由上述可知，當下底板14相對於上底板12從未收合位置滑動至收合位置時，第一鍵帽24係可下降至收合高度但第二鍵帽32仍然維持在未收合高度（如第10圖所示），藉以產生按鍵局部下降功效而協助使用者可精準地對第二按鍵106進行頻繁快速之按壓操作而不會誤按壓到鍵帽高度下降的第一按鍵104，從而大大地提升鍵盤100之操作便利性與按鍵按壓精準度。Through the above design, when the keyboard 100 configured with the first button 104 and the second button 106 is applied to a portable electronic device (such as a notebook computer) generally having an opening and closing mechanism composed of an upper cover and a lower case, the keyboard 100 can drive the lower bottom plate 14 to slide relative to the upper bottom plate 12 with the upper cover of the portable electronic device closed relative to the lower casing, so that the first keycap 24 can be lowered to the folding height as shown in FIG. Therefore, the thin design of the portable electronic device is facilitated and the problem of the keycap injury and the display screen mentioned in the prior art is effectively solved. In addition, in the application scenario where the user only needs to perform the frequent and fast pressing operation on the second button 106, it can be seen from the above that when the lower bottom plate 14 slides from the unfolded position to the folded position with respect to the upper bottom plate 12, The first keycap 24 can be lowered to the folding height but the second keycap 32 is still maintained at the unfolded height (as shown in FIG. 10), thereby generating a partial drop effect of the button to assist the user in accurately targeting the second The button 106 performs a frequent and rapid pressing operation without accidentally pressing the first button 104 whose key cap height is lowered, thereby greatly improving the operational convenience of the keyboard 100 and the button pressing accuracy.
需注意的是，在此實施例中，當上述下底板14相對於上底板12滑動至收合位置時，電路板102係可關閉第一機械軸觸發開關108，使得第一按鍵104於第一鍵帽24被按壓時不觸發第一機械軸觸發開關108，如此一來，即使在使用者不慎按壓到鍵帽高度下降之第一按鍵104的情況下，第一按鍵104仍然不會被觸發，從而確實地避免使用者誤按壓的問題。 以上所述僅為本發明之較佳實施例，凡依本發明申請專利範圍所做之均等變化與修飾，皆應屬本發明之涵蓋範圍。 It should be noted that, in this embodiment, when the lower bottom plate 14 is slid relative to the upper bottom plate 12 to the folded position, the circuit board 102 can close the first mechanical axis trigger switch 108, so that the first button 104 is first. When the key cap 24 is pressed, the first mechanical shaft trigger switch 108 is not triggered, so that even if the user accidentally presses the first button 104 whose key cap height is lowered, the first button 104 is still not triggered. Therefore, the problem of the user's accidental pressing is surely avoided. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
