Description

鍵盤keyboard

本創作關於一種鍵盤，特別是關於一種應用在可稀釋電子裝置的鍵盤。This creation is about a keyboard, especially a keyboard used in dilutable electronic devices.

就目前電腦的使用習慣而言，鍵盤為不可或缺的輸入設備之一。不論是電腦本身或是其周邊產品，皆朝著輕、薄、短、小的設計理念發展。而鍵盤亦從早期的大型架構，轉變為薄型鍵盤。薄型鍵盤的主要架構包括底板、薄膜式電路板及複數個按鍵。薄膜式電路板及按鍵設置在底板上，且薄膜式電路板位於按鍵下方。各個按鍵具有一彈性元件。當按鍵被按壓時，彈性元件抵壓薄膜式電路板，使薄膜式電路板的正極層與負極層相互接觸而導通，進而可傳送電子訊號。In terms of current computer usage habits, the keyboard is one of the indispensable input devices. Whether it is the computer itself or its peripheral products, the design concept is developing towards light, thin, short, and small. The keyboard has also changed from an early large-scale structure to a thin keyboard. The main structure of the thin keyboard includes a bottom plate, a membrane circuit board and a plurality of keys. The film type circuit board and the keys are arranged on the bottom plate, and the film type circuit board is located under the keys. Each button has an elastic element. When the button is pressed, the elastic element presses the film type circuit board, so that the positive electrode layer and the negative electrode layer of the film type circuit board are in contact with each other and conduction, thereby transmitting electronic signals.

又，鍵盤經常應用在可攜式電子裝置（例如筆記型電腦）。可攜式電子裝置包括上殼體（顯示面板）及下殼體，鍵盤設置在下殼體。可攜式電子裝置不使用時，上殼體蓋闔於下殼體。此時，上殼體可能會按壓到位於鍵盤的按鍵，使薄膜式電路板長期處在受壓的狀態，進而使薄膜式電路板變形或產生靈敏的現象。換言之，即便沒有按壓按鍵，也會因薄膜式電路板變形而產生輸入訊號。In addition, keyboards are often used in portable electronic devices (such as notebook computers). The portable electronic device includes an upper casing (display panel) and a lower casing, and the keyboard is arranged on the lower casing. When the portable electronic device is not in use, the upper casing cover is closed on the lower casing. At this time, the upper casing may press the keys on the keyboard, so that the film type circuit board will be in a long-term pressure state, and the film type circuit board may be deformed or sensitive. In other words, even if the button is not pressed, the input signal will be generated due to the deformation of the membrane circuit board.

有鑑於上述課題，本創作之主要目的是在提供一種鍵盤，藉由框架具有凸部的結構，並可抵頂蓋闔狀態之可攜式電子裝置的上殼體，以解決習知鍵盤的薄膜是電路板容易因長期壓迫而變形的問題。In view of the above-mentioned problems, the main purpose of this creation is to provide a keyboard with a structure with a protruding part in the frame, which can be used to support the upper casing of a portable electronic device with the top cover closed, so as to solve the problem of the conventional keyboard film It is a problem that the circuit board is easily deformed due to long-term compression.

為達成上述之目的，本創作提供一種鍵盤，其應用於一可攜式電子裝置。可攜式電子裝置包括相互樞接的一第一殼體及一第二殼體，鍵盤設置於第一殼體。鍵盤包括一底板、一薄膜電路板、複數按鍵以及一框架。薄膜電路板設置於底板之上。按鍵分別包括一鍵帽及一彈性件。彈性件設置於鍵帽與薄膜電路板之間。彈性件具有一觸發部，當鍵帽被按壓時，觸發部與薄膜電路板接觸。框架設置於底板的上方，且薄膜電路板位於底板與框架之間。框架包括複數容置部及至少一凸部。該些容置部分別容置該些按鍵。凸部往鍵帽的方向凸出。當第二殼體蓋闔於第一殼體，凸部抵頂第二殼體。To achieve the above-mentioned purpose, the present invention provides a keyboard which is applied to a portable electronic device. The portable electronic device includes a first housing and a second housing pivotally connected to each other, and the keyboard is arranged in the first housing. The keyboard includes a bottom plate, a thin film circuit board, a plurality of keys, and a frame. The film circuit board is arranged on the bottom plate. The keys respectively include a key cap and an elastic member. The elastic piece is arranged between the key cap and the film circuit board. The elastic member has a trigger part, and when the key cap is pressed, the trigger part contacts the film circuit board. The frame is arranged above the bottom plate, and the film circuit board is located between the bottom plate and the frame. The frame includes a plurality of accommodating parts and at least one convex part. The accommodating parts respectively accommodate the keys. The convex part protrudes in the direction of the key cap. When the second housing cover is closed on the first housing, the convex portion abuts against the second housing.

根據本創作之一實施例，凸部的一頂面高於鍵帽，或該頂面與鍵帽位於相同高度。According to an embodiment of the present invention, a top surface of the convex portion is higher than the key cap, or the top surface and the key cap are at the same height.

根據本創作之一實施例，觸發部與薄膜電路板之間具有一間隔距離。凸部低於鍵帽一預定高度，且預定高度小於等於間隔距離。According to an embodiment of the present invention, there is a separation distance between the trigger part and the film circuit board. The convex portion is lower than the key cap by a predetermined height, and the predetermined height is less than or equal to the separation distance.

根據本創作之一實施例，凸部位於其中二該容置部之間。According to an embodiment of the present invention, the convex part is located between two of the accommodating parts.

根據本創作之一實施例，凸部鄰近於框架的四個角落。According to an embodiment of the present creation, the convex portion is adjacent to the four corners of the frame.

承上所述，依據本創作之鍵盤，其應用在具有相互樞接之第一殼體及第二殼體的可攜式電子裝置，且鍵盤設置在第一殼體。鍵盤的框架具有凸部，且凸部往按鍵之鍵帽的方向凸出。當第二殼體蓋闔於第一殼體，凸部抵頂第二殼體，進而可避免第二殼體按壓到按鍵。因此，可避免薄膜電路板持續地被觸發，亦可避免薄膜電路板因長期被按壓變形的情況。As mentioned above, the keyboard according to the present invention is applied to a portable electronic device having a first housing and a second housing pivotally connected to each other, and the keyboard is arranged in the first housing. The frame of the keyboard has a convex part, and the convex part protrudes in the direction of the keycap of the button. When the second housing cover is closed to the first housing, the convex portion abuts against the second housing, thereby preventing the second housing from being pressed against the button. Therefore, the thin-film circuit board can be prevented from being triggered continuously, and the thin-film circuit board can be prevented from being deformed due to long-term pressing.

為能讓貴審查委員能更瞭解本創作之技術內容，特舉較佳具體實施例說明如下。In order to allow your reviewer to better understand the technical content of this creation, a preferred specific embodiment is described as follows.

圖1為本創作之第一實施例之鍵盤應用於可攜式電子裝置的示意圖，圖2為圖1所示之A區域的分解示意圖。請同時參考圖1及圖2所示。本實施例之鍵盤1應用於一可攜式電子裝置9。可攜式電子裝置9包括相互樞接的一第一殼體91及一第二殼體92。又，可攜式電子裝置9可以為筆記型電腦，或是其他具有二殼體的電子裝置。在本實施例中，鍵盤1設置於第一殼體91，第二殼體92可相對於第一殼體91轉動，使可攜式電子裝置9呈現開啟（使用）狀態或蓋闔狀態。FIG. 1 is a schematic diagram of the keyboard of the first embodiment of the creation applied to a portable electronic device, and FIG. 2 is an exploded schematic diagram of area A shown in FIG. 1. Please refer to Figure 1 and Figure 2 at the same time. The keyboard 1 of this embodiment is applied to a portable electronic device 9. The portable electronic device 9 includes a first housing 91 and a second housing 92 pivotally connected to each other. Moreover, the portable electronic device 9 may be a notebook computer or other electronic devices with two housings. In this embodiment, the keyboard 1 is disposed in the first housing 91, and the second housing 92 can rotate relative to the first housing 91, so that the portable electronic device 9 is in an open (used) state or a closed state.

如圖2所示，本實施例之鍵盤1包括一底板10、一薄膜電路板20、複數按鍵30以及一框架40。須說明的是，為求圖面簡潔，圖2僅限示其中一個按鍵30的示意圖。其中，薄膜電路板20設置於底板10之上。其中，底板10具有組裝按鍵30的卡勾結構11，對應的，薄膜電路板20也具有開口21，以供卡勾結構11穿過。另外，薄膜電路板20亦具有開關感應區22，分別對應於其中一個按鍵30。一般而言，薄膜電路板20為三層薄膜結構，包含正極層、負極層及不導電層。不導電層設置在正極層及負極層之間，而開關感應區22則不配置不導電層。As shown in FIG. 2, the keyboard 1 of this embodiment includes a bottom plate 10, a thin film circuit board 20, a plurality of keys 30 and a frame 40. It should be noted that, for the sake of simplicity, FIG. 2 only shows a schematic diagram of one of the buttons 30. Among them, the thin film circuit board 20 is disposed on the bottom plate 10. Wherein, the bottom plate 10 has a hook structure 11 for assembling the keys 30, and correspondingly, the film circuit board 20 also has an opening 21 for the hook structure 11 to pass through. In addition, the thin film circuit board 20 also has a switch sensing area 22 corresponding to one of the buttons 30 respectively. Generally speaking, the thin film circuit board 20 has a three-layer thin film structure, including a positive electrode layer, a negative electrode layer and a non-conductive layer. The non-conductive layer is provided between the positive electrode layer and the negative electrode layer, and the switch sensing area 22 is not provided with a non-conductive layer.

又，按鍵30分別包括一鍵帽31、一彈性件32及一連接件33。連接件33用以連接底板10的卡勾結構11及鍵帽31，並導引鍵帽31相對於底板10升降。連接件33例如是剪刀式連接件。圖3為圖2所示之按鍵於組裝後的剖面示意圖，須說明的是，為求圖面簡潔，圖3並未繪製連接件33。請同時參考圖1、圖2及圖3所示。彈性件32設置於鍵帽31與薄膜電路板20之間，且彈性件32具有一觸發部321，其對應於開關感應區22。本實施例之觸發部321為彈性件32內部的凸柱。當鍵帽31未被按壓時，觸發部321與薄膜電路板20之間具有一間隔距離D，如圖3所示。當鍵帽31被按壓時，彈性件32被鍵帽31壓迫向下（即往薄膜電路板20的方向）移動，使觸發部321與薄膜電路板的開關感應區22接觸。由於開關感應區22沒有配置不導電層，使開關感應區22被觸發部321按壓時，正極層與負極層可相互接觸而導通，進而產生對應的電子訊號。又，彈性件32同時具有復位的功能，在按鍵30未被按壓時，可使鍵帽31回復到未被按壓前的高度。In addition, the keys 30 include a key cap 31, an elastic member 32, and a connecting member 33, respectively. The connecting member 33 is used to connect the hook structure 11 of the bottom plate 10 and the key cap 31 and guide the key cap 31 to move up and down relative to the bottom plate 10. The connecting member 33 is, for example, a scissors-type connecting member. FIG. 3 is a schematic cross-sectional view of the button shown in FIG. 2 after being assembled. It should be noted that, for the sake of simplicity, the connecting member 33 is not drawn in FIG. 3. Please refer to Figure 1, Figure 2 and Figure 3 at the same time. The elastic member 32 is disposed between the key cap 31 and the film circuit board 20, and the elastic member 32 has a trigger portion 321 corresponding to the switch sensing area 22. The trigger portion 321 of this embodiment is a convex post inside the elastic member 32. When the key cap 31 is not pressed, there is a separation distance D between the trigger portion 321 and the film circuit board 20, as shown in FIG. 3. When the key cap 31 is pressed, the elastic member 32 is pressed by the key cap 31 to move downward (that is, toward the direction of the film circuit board 20), so that the trigger portion 321 contacts the switch sensing area 22 of the film circuit board. Since the switch sensing area 22 is not provided with a non-conductive layer, when the switch sensing area 22 is pressed by the trigger portion 321, the positive electrode layer and the negative electrode layer can be in contact with each other and conduct, thereby generating corresponding electronic signals. In addition, the elastic member 32 also has a reset function, when the key 30 is not pressed, the key cap 31 can be restored to the height before the key 30 is not pressed.

本實施例之框架40設置於底板10的上方，且薄膜電路板20位於底板10與框架40之間。圖4為圖1所示之框架的示意圖，請搭配參考圖4所示。框架40包括複數容置部41及至少一凸部42。容置部41分別容置按鍵30，亦即，按鍵30分別安裝至容置部41內。其中，鍵帽31的部分自容置部41露出，以供使用者按壓按鍵30。在本實施例中，凸部42往鍵帽31的方向凸出。當第二殼體92蓋闔於第一殼體91，凸部42可抵頂第二殼體92。具體而言，本實施例之凸部42的一頂面421高於鍵帽31，如圖3所示。當第二殼體92蓋闔於第一殼體91，第二殼體92僅接觸到框架40的凸部42，進而可避免第二殼體92按壓到按鍵30。因此，可避免薄膜電路板20持續地被觸發，亦可避免薄膜電路板20因長期被按壓變形的情況。In this embodiment, the frame 40 is disposed above the bottom plate 10, and the film circuit board 20 is located between the bottom plate 10 and the frame 40. Fig. 4 is a schematic diagram of the frame shown in Fig. 1, please refer to Fig. 4. The frame 40 includes a plurality of accommodating portions 41 and at least one convex portion 42. The accommodating part 41 accommodates the keys 30 respectively, that is, the keys 30 are respectively installed in the accommodating parts 41. Wherein, a part of the key cap 31 is exposed from the containing part 41 for the user to press the key 30. In this embodiment, the convex portion 42 protrudes toward the key cap 31. When the second housing 92 is closed on the first housing 91, the protrusion 42 can abut against the second housing 92. Specifically, a top surface 421 of the convex portion 42 of this embodiment is higher than the key cap 31, as shown in FIG. 3. When the second housing 92 is closed on the first housing 91, the second housing 92 only touches the convex portion 42 of the frame 40, thereby preventing the second housing 92 from being pressed to the button 30. Therefore, the thin film circuit board 20 can be prevented from being triggered continuously, and the thin film circuit board 20 can also be prevented from being deformed due to long-term pressing.

在一些實施例中，凸部42的頂面421可與鍵帽31位於相同高度。當第二殼體92蓋闔於第一殼體91，第二殼體92同時接觸到鍵帽31及框架40的凸部42。因凸部42（固定不動的元件）的設置，亦可避免第二殼體92繼續向下按壓鍵帽31。同樣可避免薄膜電路板20持續地被觸發，亦可避免薄膜電路板20因長期被按壓變形的情況。In some embodiments, the top surface 421 of the convex portion 42 may be at the same height as the key cap 31. When the second housing 92 is closed on the first housing 91, the second housing 92 is in contact with the keycap 31 and the protrusion 42 of the frame 40 at the same time. Due to the arrangement of the convex portion 42 (fixed component), the second housing 92 can also be prevented from continuing to press the key cap 31 downward. It can also prevent the thin film circuit board 20 from being triggered continuously, and it can also prevent the thin film circuit board 20 from being deformed due to long-term pressing.

在一些實施例中，凸部42之頂面421的高度亦可略低於鍵帽31。具體而言，凸部42低於鍵帽31一預定高度，且預定高度小於等於間隔距離D。當第二殼體92蓋闔於第一殼體91時，第二殼體92會些微地按壓鍵帽31。然而，由於預定高度小於等於間隔距離D，故在彈性件32的觸發部321接觸到薄膜電路板20之前，或是觸發部321輕輕觸及薄膜電路板20時，第二殼體92即可被凸部42抵頂，以阻止第二殼體92繼續向下按壓鍵帽31，同樣可避免薄膜電路板20持續地被觸發，亦可避免薄膜電路板20因長期被按壓變形的情況。In some embodiments, the height of the top surface 421 of the protrusion 42 may be slightly lower than that of the key cap 31. Specifically, the convex portion 42 is lower than the key cap 31 by a predetermined height, and the predetermined height is less than or equal to the separation distance D. When the second housing 92 is closed on the first housing 91, the second housing 92 slightly presses the key cap 31. However, since the predetermined height is less than or equal to the separation distance D, the second housing 92 can be removed before the trigger portion 321 of the elastic member 32 touches the film circuit board 20 or when the trigger portion 321 touches the film circuit board 20 lightly. The protrusion 42 is pressed against the top to prevent the second housing 92 from continuing to press the key cap 31 downwards, which can also prevent the thin film circuit board 20 from being continuously triggered, and can also prevent the thin film circuit board 20 from being deformed due to long-term pressing.

須說明的是，本實施例不限制凸部42的數量及其分布位置，僅需達到抵頂第二殼體92的效果。較佳的，凸部42鄰近於框架40的四個角落（corner）。當第二殼體92蓋闔於第一殼體91時，凸部42即可對應抵頂第二殼體92的四個角落。較佳的，凸部42位於其中二個容置部41之間，進而使相鄰的按鍵30皆可避免被第二殼體92所按壓。It should be noted that the present embodiment does not limit the number and distribution positions of the protrusions 42, and only needs to achieve the effect of pressing against the second housing 92. Preferably, the convex portion 42 is adjacent to the four corners of the frame 40. When the second housing 92 is closed on the first housing 91, the protrusion 42 can correspondingly abut the four corners of the second housing 92. Preferably, the convex portion 42 is located between the two accommodating portions 41, so that the adjacent keys 30 can be prevented from being pressed by the second housing 92.

另外，本實施例亦未限制凸部42的構型。較佳的，凸部42為一弧形結構，以形成類似拱橋的結構，如圖2所示。由於凸部42為弧形結構，故頂面421為平緩而無尖角的平面。當第二殼體92蓋闔於第一殼體91時，凸部42以平緩的弧面（頂面421）與第二殼體92接觸，進而可避免刮傷、或破壞第二殼體92的內表面（通常為顯示面板的表面）。In addition, this embodiment also does not limit the configuration of the convex portion 42. Preferably, the convex portion 42 is an arc structure to form a structure similar to an arch bridge, as shown in FIG. 2. Since the convex portion 42 has an arc structure, the top surface 421 is a flat surface without sharp corners. When the second housing 92 is closed on the first housing 91, the convex portion 42 contacts the second housing 92 with a gentle arc surface (top surface 421), thereby avoiding scratches or damage to the second housing 92 The inner surface (usually the surface of the display panel).

凸部42可以為單獨的構件，並設置於框架40朝向第一殼體91的該側。較佳的，凸部42與框架40可以為一體成型的結構，例如以射出成型的方式製成框架40及其凸部42。又，本實施例並未限制凸部42的材質。較佳的，凸部42可由一軟質材料所組成。舉例而言，可利用雙料射出的方式製成框架40及其凸部42。具體而言，先以金屬材料射出形成框架40的主體結構，再以軟質材料射出形成凸部42。其中，軟質材料可例如但不限於塑膠、或橡膠等材料。同樣的，當第二殼體92蓋闔於第一殼體91時，以軟質材料製成的凸部42與第二殼體92接觸，同樣可達到避免刮傷、或避免破壞第二殼體92之內表面的效果。The convex portion 42 may be a separate member and is provided on the side of the frame 40 facing the first housing 91. Preferably, the convex portion 42 and the frame 40 may be an integrally formed structure, for example, the frame 40 and the convex portion 42 are formed by injection molding. Moreover, this embodiment does not limit the material of the convex portion 42. Preferably, the protrusion 42 can be composed of a soft material. For example, the frame 40 and its protrusion 42 can be made by two-material injection. Specifically, a metal material is first injected to form the main structure of the frame 40, and then a soft material is injected to form the convex portion 42. Among them, the soft material can be, for example, but not limited to, plastic or rubber. Similarly, when the second housing 92 is closed on the first housing 91, the convex portion 42 made of soft material is in contact with the second housing 92, which can also avoid scratches or damage to the second housing. The effect of the inner surface of 92.

綜上所述，依據本創作之鍵盤，其應用在具有相互樞接之第一殼體及第二殼體的可攜式電子裝置，且鍵盤設置在第一殼體。鍵盤的框架具有凸部，且凸部往按鍵之鍵帽的方向凸出。當第二殼體蓋闔於第一殼體，凸部抵頂第二殼體，進而可避免第二殼體按壓到按鍵。因此，可避免薄膜電路板持續地被觸發，亦可避免薄膜電路板因長期被按壓變形的情況。In summary, the keyboard according to the present creation is applied to a portable electronic device with a first housing and a second housing pivotally connected to each other, and the keyboard is arranged in the first housing. The frame of the keyboard has a convex part, and the convex part protrudes in the direction of the keycap of the button. When the second housing cover is closed to the first housing, the convex portion abuts against the second housing, thereby preventing the second housing from being pressed against the button. Therefore, the thin-film circuit board can be prevented from being triggered continuously, and the thin-film circuit board can be prevented from being deformed due to long-term pressing.
