鍵盤裝置及其按鍵結構 Keyboard device and its key structure

本發明係涉及電腦周邊裝置的領域，尤其係關於一種輸入裝置。 The present invention relates to the field of computer peripheral devices, and particularly relates to an input device.

常見的電腦週邊之輸入裝置包括滑鼠裝置、鍵盤裝置1以及軌跡球裝置等，其中鍵盤裝置可供使用者直接地將文字以及符號輸入至電腦，因此相當受到重視。 Common input devices around the computer include a mouse device, a keyboard device 1, and a trackball device. Among them, the keyboard device allows the user to directly input text and symbols into the computer, so it is highly valued.

首先說明習知鍵盤裝置之結構以及功能，請參閱圖1~圖4，圖1為習知鍵盤裝置之外觀結構示意圖，圖2為圖1所示鍵盤裝置之部份結構的立體示意圖，圖3為圖2所示鍵盤裝置之部份結構的立體分解示意圖，圖4為圖2所示鍵盤裝置之部份結構的剖面概念示意圖。為了更清楚地示意，圖2~圖4中僅繪出部份鍵框、單一按鍵結構及相關元件結構。 First, explain the structure and function of the conventional keyboard device. Please refer to Figures 1 to 4. Figure 1 is a schematic diagram of the appearance structure of the conventional keyboard device. Figure 2 is a three-dimensional schematic diagram of part of the structure of the keyboard device shown in Figure 1, and Figure 3 FIG. 2 is a perspective exploded schematic diagram of a partial structure of the keyboard device shown in FIG. 2, and FIG. 4 is a conceptual cross-sectional schematic diagram of a partial structure of the keyboard device shown in FIG. 2. For a clearer illustration, only part of the key frame, single key structure, and related component structures are depicted in FIGS. 2 to 4.

習知的鍵盤裝置1包括複數個按鍵結構10、按鍵底板11、薄膜線路板12以及鍵框13，且薄膜線路板12上具有相對應於複數按鍵結構10的複數薄膜開關121，而每一按鍵結構10包括鍵帽101、剪刀式連接元件102以及彈性體103，剪刀式連接元件102則連接於鍵帽101以及按鍵底板11之間，並包括第一框架1021以及樞接於第一框架1021的第二框架1022，因此第一框架1021與第二框架1022可彼此相對擺動。此外，彈性體103係設置於鍵帽101與按鍵底板11之間，並具有抵頂部(圖未示)。 The conventional keyboard device 1 includes a plurality of key structures 10, a key base plate 11, a thin film circuit board 12, and a key frame 13, and the thin film circuit board 12 has a plurality of membrane switches 121 corresponding to the plurality of key structures 10, and each key The structure 10 includes a key cap 101, a scissor-type connecting element 102, and an elastic body 103. The scissor-type connecting element 102 is connected between the key cap 101 and the key base plate 11, and includes a first frame 1021 and a first frame 1021 pivotally connected to the first frame 1021. The second frame 1022, so the first frame The frame 1021 and the second frame 1022 can swing relative to each other. In addition, the elastic body 103 is disposed between the key cap 101 and the key base plate 11, and has a top portion (not shown).

其中，當任一按鍵結構10的鍵帽101被觸壓而相對於按鍵底板11往下移動時，剪刀式連接元件102的第一框架1021與第二框架1022會由開合狀態變更為疊合狀態，且往下移動的鍵帽101會擠壓彈性體103，使彈性體103的抵頂部抵頂並觸發相對應的薄膜開關121，而使鍵盤裝置1產生相對應的按鍵訊號。而當按鍵結構10的鍵帽101不再被觸壓時，鍵帽101會因應彈性體103的彈性力而相對於按鍵底板11往上移動，此時第一框架1021與第二框架1022會由疊合狀態變更為開合狀態，且鍵帽101會恢復原位。 Wherein, when the key cap 101 of any key structure 10 is pressed and moved downward relative to the key base plate 11, the first frame 1021 and the second frame 1022 of the scissor connection element 102 will be changed from the open and closed state to the overlapped state. When the keycap 101 moves downward, it squeezes the elastic body 103 so that the top of the elastic body 103 presses against and triggers the corresponding membrane switch 121, so that the keyboard device 1 generates a corresponding key signal. When the key cap 101 of the key structure 10 is no longer pressed, the key cap 101 will move upward relative to the key base plate 11 in response to the elastic force of the elastic body 103. At this time, the first frame 1021 and the second frame 1022 will be moved by The overlapped state is changed to the open and closed state, and the keycap 101 will return to its original position.

再者，鍵框13設置於薄膜線路板12的上方，並具有框體132以及分別對應於複數個按鍵結構10的複數個容置孔131，且每一容置孔131用以供相對應之按鍵結構10的鍵帽101活動於其中。然而，由於習知鍵盤裝置1的鍵帽101僅僅是靠著剪刀式連接元件102而固定於按鍵底板11上，因此鍵帽101於受到敲擊外力時容易從鍵盤裝置1上脫落下來。 Furthermore, the key frame 13 is disposed above the film circuit board 12, and has a frame body 132 and a plurality of accommodating holes 131 respectively corresponding to the plurality of key structures 10, and each accommodating hole 131 is used for corresponding The key cap 101 of the key structure 10 is movable therein. However, since the keycap 101 of the conventional keyboard device 1 is only fixed to the key base plate 11 by the scissor-type connecting element 102, the keycap 101 is easily detached from the keyboard device 1 when subjected to an external force.

有鑑於此，具有防掉鍵設計的鍵盤裝置被提出。請參閱圖5，其為習知具有防掉鍵設計之鍵盤裝置的部份結構剖面示意圖，其亦為本案申請人於台灣發明專利第TWI669729申請號所提出的鍵盤裝置。鍵盤裝置1’大致類似於鍵盤裝置1，不同之處在於，鍵盤裝置1’還包括設置鍵框13上方的限位框14，且限位框14包括框體142以及分別對應於複數個按鍵結構10並縱向貫穿框體142的複數個容置孔141；其中，限位框14之任一容置孔 141與鍵框13上相對應之容置孔131係相互連通，且限位框14之每一容置孔141的開口小於鍵框13上相對應之容置孔131的開口。 In view of this, a keyboard device with a key drop prevention design has been proposed. Please refer to FIG. 5, which is a schematic cross-sectional view of a part of the structure of a conventional keyboard device with a key drop prevention design. It is also a keyboard device proposed by the applicant in the Taiwan Invention Patent No. TWI669729. The keyboard device 1'is roughly similar to the keyboard device 1, except that the keyboard device 1'also includes a limit frame 14 provided above the key frame 13, and the limit frame 14 includes a frame body 142 and respectively corresponds to a plurality of key structures 10 and longitudinally penetrate through a plurality of accommodating holes 141 of the frame body 142; among them, any accommodating hole of the limit frame 14 141 and the corresponding accommodating holes 131 on the key frame 13 are communicated with each other, and the opening of each accommodating hole 141 of the limit frame 14 is smaller than the opening of the corresponding accommodating hole 131 on the key frame 13.

再者，每一按鍵結構10’還包括側翼部104，且側翼部104的一端連接於鍵帽101的側緣，而側翼部104的另一端由鍵帽101的側緣向外延伸至框體142的下方，如此一來，側翼部104與框體142之間形成干涉關係。是以，當鍵帽101受到較大的敲擊外力或被摳弄時，由於限位框14的框體142對按鍵結構10的側翼部104提供了限位作用，因此鍵帽101不容易從鍵盤裝置1’上脫落下來。 Furthermore, each key structure 10' further includes a side wing 104, and one end of the side wing 104 is connected to the side edge of the key cap 101, and the other end of the side wing 104 extends outward from the side edge of the key cap 101 to the frame body. Below 142, in this way, the side wing 104 and the frame 142 form an interference relationship. Therefore, when the keycap 101 is subjected to a large external force of percussion or is knocked, since the frame 142 of the limit frame 14 provides a limit effect on the side wing portion 104 of the key structure 10, the keycap 101 cannot be easily removed from The keyboard device 1'falls off.

然而，申請人潛心研究後發現，僅利用按鍵結構10’與限位框14之間的干涉關係來防止鍵帽101脫落的效果仍相當有限，一旦鍵帽101受到較大的敲擊外力或被刻意摳弄時，如應用於教育市場時，側翼部104仍可能產生形變而克服其與限位框14之間的干涉關係，進而導致鍵帽101鬆脫與滑落。是以，習知的鍵盤裝置1’仍具有改善的空間。 However, the applicant found after intensive research that the effect of only using the interference relationship between the key structure 10' and the limit frame 14 to prevent the keycap 101 from falling off is still quite limited. When deliberately, such as when used in the education market, the side wing 104 may still be deformed to overcome the interference relationship between it and the limit frame 14, which may cause the keycap 101 to loosen and fall off. Therefore, the conventional keyboard device 1'still has room for improvement.

本發明之一目的在提供一種其側翼部從其鍵帽側緣側向延伸並具有穿孔的按鍵結構。 One of the objects of the present invention is to provide a key structure with its side wings extending laterally from the side edge of the key cap and having perforations.
