Description
本發明涉及輸入裝置領域，尤其係關於一種適用於平板電腦的鍵盤裝置。 The present invention relates to the field of input devices, and in particular, to a keyboard device suitable for tablet computers.
由於平板電腦或其它整合有觸控螢幕的電子裝置能提供更為簡易且直覺的操作模式，故已成為現代人在生活中或工作上不可或缺的工具。進一步而言，當使用者需要進行文字訊息的輸入時，平板電腦或電子裝置多於其觸控螢幕上顯示虛擬鍵盤，以供使用者觸碰輸入文字訊息至平板電腦或電子裝置，但受限於觸控螢幕的尺寸或感測靈敏度，使用者僅是藉由手指觸碰螢幕上的虛擬鍵盤來模擬觸發按鍵的動作，當平板電腦或電子裝置未能即時回應使用者的觸碰行為時，極易造成使用者使用上的困擾，因此，透過顯示於觸控螢幕上的虛擬鍵盤較不利於進行大量且長時間的輸入作業，且無法如鍵盤裝置反饋給使用者紮實的操作手感。 Tablet computers or other electronic devices integrated with touch screens have become indispensable tools for modern people in life or work because they can provide a simpler and more intuitive operation mode. Furthermore, when the user needs to input text messages, the tablet computer or electronic device often displays a virtual keyboard on its touch screen for the user to touch input text messages to the tablet computer or electronic device, but this is limited Due to the size or sensing sensitivity of the touch screen, the user only touches the virtual keyboard on the screen to simulate the action of triggering the keys. When the tablet or electronic device cannot respond to the user's touch behavior in real time, It is very easy to cause trouble to the user. Therefore, the virtual keyboard displayed on the touch screen is not conducive to large-scale and long-term input operations, and it cannot give the user a solid operating feel like a keyboard device.
如何針對上述的問題進行改善，實為本領域相關人員所關注的焦點。 How to improve the above problems is actually the focus of relevant people in this field.

The deformable portion 1011 of the key base 101 has a lower surface F facing the touch screen 20 . The keycap 102 is disposed above the key base 101 , and the keycap 102 includes a pressing surface 1021 and an inner surface 1022 that are opposite to each other. The actuating cylinder 103 is disposed on the inner surface 1022 of the keycap 102 , and the actuating cylinder 103 extends from the inner surface 1022 of the keycap 102 in a direction close to the key bottom plate 101 and corresponds to the deformable portion 1011 of the key bottom plate 101 . The conductive film 104 is arranged on the lower surface F of the deformable part 1011.
在本實施例中，當鍵帽102被觸壓時，如圖3所示，鍵帽102朝靠近按鍵底板101的方向下降移動的過程中，鍵帽102帶動做動柱體103朝靠近按鍵底板101的方向移動並抵壓按鍵底板101的可形變部1011，使得按鍵底板101的可形變部1011產生向下凹陷的形變，並在可形變部1011向下凹陷形變的過程中，可形變部1011帶動導電薄膜104接觸於平板電腦2的觸控螢幕20，此時，顯示於觸控螢幕20上的虛 擬鍵盤的其中之一觸控位置被導電薄膜104觸發，進而產生與此觸控位置相應的輸入字元或功能的觸控訊號。 In this embodiment, when the keycap 102 is pressed, as shown in FIG. 3 , when the keycap 102 moves downward toward the key base 101 , the keycap 102 drives the actuating cylinder 103 toward the key base 101 . The deformable part 1011 of the key base plate 101 moves in the direction of 101 and presses the deformable part 1011 of the key base plate 101, causing the deformable part 1011 of the key base plate 101 to deform downwardly, and in the process of the deformable part 1011 deforming downwardly, the deformable part 1011 The conductive film 104 is driven to contact the touch screen 20 of the tablet computer 2. At this time, the virtual image displayed on the touch screen 20 One of the touch positions of the pseudo keyboard is triggered by the conductive film 104, thereby generating a touch signal corresponding to the input character or function of the touch position.
在本實施例中，當鍵帽102不再被按壓時，按鍵底板101的可形變部1011在形變恢復的過程中提供彈性回復力予做動柱體103，使得做動柱體103推動鍵帽102朝遠離按鍵底板101的方向上升移動至如圖2所示之未被觸壓前的位置。 In this embodiment, when the keycap 102 is no longer pressed, the deformable portion 1011 of the key base 101 provides an elastic restoring force to the actuating cylinder 103 during the deformation recovery process, so that the actuating cylinder 103 pushes the keycap. 102 moves upward and away from the key bottom plate 101 to the position before being touched as shown in FIG. 2 .

綜上所述，本發明實施例的鍵盤裝置，其按鍵結構被觸壓後是藉由做動柱體抵壓按鍵底板的可形變部，再透過可形變部形變過程 中帶動導電薄膜來接觸平板電腦的觸控螢幕，在做動柱體間接接觸觸控螢幕的結構設計下，可以避免質地較為剛性的做動柱體直接接觸平板電腦的觸控螢幕，有效保護平板電腦的觸控螢幕，進而降低平板電腦的觸控螢幕損壞的機率。此外，本發明實施例的鍵盤裝置內部完全沒有任何電子材料或是軟性電路板，具有製作成本低廉的優點，也由於內部沒有任何電子材料或是軟性電路板，因此無須額外設計較為精密的防水結構來防止外界水氣進入到鍵盤裝置內部。 To sum up, in the keyboard device according to the embodiment of the present invention, after the key structure is pressed, the moving cylinder presses the deformable part of the key bottom plate, and then through the deformation process of the deformable part The conductive film is driven in the middle to contact the touch screen of the tablet computer. Under the structural design in which the moving cylinder indirectly contacts the touch screen, the relatively rigid moving cylinder can be prevented from directly contacting the touch screen of the tablet computer, effectively protecting the tablet. The touch screen of the computer thereby reduces the chance of damage to the touch screen of the tablet computer. In addition, the keyboard device of the embodiment of the present invention does not have any electronic materials or flexible circuit boards inside, which has the advantage of low production cost. Since there is no electronic material or flexible circuit board inside, there is no need to design an additional more sophisticated waterproof structure. To prevent external moisture from entering the interior of the keyboard device.
再者，本發明實施例的鍵盤裝置更具有以下優點： Furthermore, the keyboard device according to the embodiment of the present invention has the following advantages:
1.在其它習知鍵盤裝置的設計中，做動柱體是以直接接觸的方式來觸發觸控螢幕，因此在按鍵底板上必需要形成讓做動柱體通過的孔洞，在這樣的情況下，液體、髒污就容易從按鍵底板的孔洞進入到鍵盤裝置內部，且孔洞本身也不易清潔。由於本發明實施例的鍵盤裝置，其做動柱體是以間接接觸的方式來接觸平板電腦的觸控螢幕，因此在按鍵底板上不具有任何孔洞，有效的避免液體、髒污、進入到鍵盤裝置內部，且易於清潔。 1. In the design of other conventional keyboard devices, the actuating cylinder triggers the touch screen by direct contact. Therefore, a hole must be formed on the key base plate to allow the actuating cylinder to pass. In this case , liquids and dirt can easily enter the inside of the keyboard device through the holes in the key base plate, and the holes themselves are not easy to clean. Since the actuating cylinder of the keyboard device of the embodiment of the present invention contacts the touch screen of the tablet computer in an indirect contact manner, there are no holes on the key bottom plate, which effectively prevents liquids, dirt, and liquids from entering the keyboard. inside the unit and easy to clean.
2.在其它習知鍵盤裝置的設計中，做動柱體是以直接接觸的方式來觸發觸控螢幕，因此需要在每一個按鍵結構的做動柱上形成導電薄膜，如此為增加生產組裝的困難度，導致成本提高。而本發明實施例的鍵盤裝置，其按鍵底板是以整片一體成型的架構來進行配置，因此可以有效降低生產的組裝困難度，進而降低成本。 2. In the design of other conventional keyboard devices, the actuating cylinder triggers the touch screen by direct contact. Therefore, it is necessary to form a conductive film on the actuating cylinder of each key structure, which increases the production and assembly time. difficulty, leading to higher costs. As for the keyboard device according to the embodiment of the present invention, the key bottom plate is configured with a one-piece integrated structure, which can effectively reduce the assembly difficulty in production and thereby reduce the cost.
