按鍵及其鍵盤Keys and keyboard

本發明關於一種按鍵及其鍵盤，尤指一種使用升降支撐裝置之支撐件上之遮蔽片覆蓋於發光裝置上方之按鍵及其鍵盤。The present invention relates to a key and a keyboard thereof, in particular to a key and a keyboard that uses a shielding sheet on a support of a lifting support device to cover the top of a light emitting device.

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。隨著電腦逐漸普及，今日按鍵及鍵盤的發展除了一般的輸入功能外，亦強調視覺上的訴求，舉例來說，在鍵盤上配置有可在使用時發光之按鍵即為一具代表性之設計。常見的按鍵發光設計係在底板上配置有發光單元（如發光二極體）與相對應的電路板（如薄膜電路板、軟性電路板），藉此，發光單元所發出之光線即可向上投射出鍵帽之外，進而使按鍵產生發光的效果。In terms of current personal computer usage habits, the keyboard is one of the indispensable input devices for inputting text, symbols or numbers. With the increasing popularity of computers, the development of today’s keys and keyboards emphasizes visual appeals in addition to general input functions. For example, the keyboard is equipped with keys that emit light when in use is a representative design. . A common button lighting design is to configure a light-emitting unit (such as a light-emitting diode) and a corresponding circuit board (such as a thin-film circuit board, a flexible circuit board) on the bottom plate, so that the light emitted by the light-emitting unit can be projected upward Outside of the keycap, the keys have a luminous effect.

在先前技術中，其通常會在升降支撐裝置的支撐件對應發光單元的邊角位置裁切出相對應之L型讓位槽，以確保相鄰於升降支撐裝置的發光單元所發射之光線可順利地向上投射至鍵帽，並且可進一步地避免支撐件與發光單元發生結構干涉問題以及降低按鍵的整體結構高度。然而，上述設計往往會導致支撐件整體結構強度不佳以及鍵帽按壓作動性較差，如此一來，當使用者按壓到鍵帽上對應支撐件之L型讓位槽的位置時，往往會出現按鍵按壓無反應或甚至無法觸發的問題，從而造成使用者在按鍵按壓操作上的諸多不便。除此之外，由於發光單元與鍵帽之間並沒有額外配置相對應的遮蔽擋光結構，因此也會容易出現發光單元所發出之光線從鍵帽與底板之間的結構間隙投射而出的情況，進而產生按鍵漏光的問題而影響到按鍵之發光效果以及造成使用者在視覺上的不適。In the prior art, it usually cuts out the corresponding L-shaped relief slots at the corners of the supporting member of the lifting support device corresponding to the light emitting unit to ensure that the light emitted by the light emitting unit adjacent to the lifting support device can be It can project upward to the key cap smoothly, and can further avoid the problem of structural interference between the support and the light-emitting unit and reduce the overall structural height of the key. However, the above-mentioned design often results in poor overall structural strength of the support and poor keycap pressing action. As a result, when the user presses the keycap to the position of the L-shaped relief groove corresponding to the support, it will often appear The problem of no response or even failure to trigger the key press has caused many inconveniences for the user in the key press operation. In addition, because there is no additional light-shielding structure between the light-emitting unit and the key cap, the light emitted by the light-emitting unit is likely to be projected from the structural gap between the key cap and the bottom plate. In this case, the problem of light leakage of the keys is generated, which affects the light-emitting effect of the keys and causes visual discomfort to the user.

關於本發明之優點與精神可以藉由以下的發明詳述及所附圖式得到進一步的瞭解。The advantages and spirit of the present invention can be further understood through the following detailed description of the invention and the accompanying drawings.

請參閱第1圖以及第2圖，第1圖為根據本發明之一實施例所提出之鍵盤10之部分放大示意圖，第2圖為第1圖之鍵盤10沿剖面線A-A之剖面示意圖，其中為了清楚地顯示按鍵14之內部結構設計，鍵帽16在第1圖中以虛線簡示之。如第1圖以及第2圖所示，鍵盤10包含底板12以及複數個按鍵14（於第1圖中僅以一個按鍵14簡示）。複數個按鍵14係設置於底板12上以供使用者按壓，進而執行使用者所欲輸入的功能。本發明所提出之利用支撐件之遮蔽片覆蓋發光裝置之設計係可應用於複數個按鍵14之至少其中之一上，其數量多寡端視鍵盤10之實際應用而定，以下係針對其中之一具有上述設計之按鍵14進行描述，至於其他採用相同設計之按鍵14的結構設計，其係可以此類推。Please refer to Figures 1 and 2. Figure 1 is a partially enlarged schematic view of a keyboard 10 according to an embodiment of the present invention, and Figure 2 is a schematic cross-sectional view of the keyboard 10 of Figure 1 along the section line AA. In order to clearly show the internal structure design of the key 14, the key cap 16 is briefly shown in dotted lines in the first figure. As shown in Figures 1 and 2, the keyboard 10 includes a bottom plate 12 and a plurality of keys 14 (only one key 14 is briefly shown in Figure 1). A plurality of buttons 14 are arranged on the bottom plate 12 for the user to press, and then perform the function input by the user. The design of using the shielding sheet of the supporting member to cover the light-emitting device proposed in the present invention can be applied to at least one of the plurality of keys 14. The number depends on the actual application of the keyboard 10. The following is for one of them The key 14 with the above design is described. As for the structural design of other keys 14 with the same design, it can be deduced by analogy.

由第1圖以及第2圖可知，按鍵14包含鍵帽16、發光裝置18，以及升降支撐裝置20，發光裝置18可與底板12結合且位於鍵帽16下方，更詳細地說，在此實施例中，發光裝置18可包含薄膜電路板22以及發光單元24（如發光二極體，但不受此限），薄膜電路板22係貼附於底板12上，發光單元24係設置於薄膜電路板22上，使得按鍵14可經由薄膜電路板22進行發光單元24之發光控制，例如控制發光單元24發出閃爍光線或是不同顏色之色光等。As can be seen from Figures 1 and 2, the button 14 includes a keycap 16, a light-emitting device 18, and a lifting support device 20. The light-emitting device 18 can be combined with the bottom plate 12 and is located below the keycap 16. In more detail, it is implemented here. In an example, the light-emitting device 18 may include a thin-film circuit board 22 and a light-emitting unit 24 (such as a light-emitting diode, but not limited to this). The thin-film circuit board 22 is attached to the bottom plate 12, and the light-emitting unit 24 is disposed on the thin-film circuit. On the board 22, the button 14 can control the light emission of the light emitting unit 24 through the thin film circuit board 22, for example, controlling the light emitting unit 24 to emit flashing light or colored light of different colors.

於此針對升降支撐裝置20進行詳細的描述，請參閱第1圖、第2圖，以及第3圖，第3圖為第2圖之第一支撐件26於另一視角之放大示意圖，如第1圖、第2圖，以及第3圖所示，升降支撐裝置20係設置於底板12與鍵帽16之間且包含第一支撐件26以及第二支撐件28，第一支撐件26與第二支撐件28彼此交叉樞接且可活動地連接鍵帽16以及底板12，藉此，鍵帽16即可經由升降支撐裝置20相對於底板12做上下運動。更詳細地說，在此實施例中，由第3圖可知，第一支撐件26往發光單元24延伸形成有遮蔽片30以覆蓋於發光單元24上方，遮蔽片30對應發光單元24之位置具有出光口32，藉此，發光單元24發射之光線可通過出光口32射向鍵帽16，進而使按鍵14產生發光效果。For a detailed description of the lifting support device 20, please refer to Figure 1, Figure 2, and Figure 3. Figure 3 is an enlarged schematic view of the first support member 26 in Figure 2 from another perspective, as shown in Figure 1. As shown in Figure 1, Figure 2, and Figure 3, the lifting support device 20 is disposed between the bottom plate 12 and the keycap 16 and includes a first support 26 and a second support 28, the first support 26 and the second support 26 The two support members 28 are pivotally connected to each other and movably connect the keycap 16 and the bottom plate 12, so that the keycap 16 can move up and down relative to the bottom plate 12 via the lifting support device 20. In more detail, in this embodiment, as can be seen from Figure 3, the first support 26 extends toward the light-emitting unit 24 to form a shielding sheet 30 to cover the light-emitting unit 24. The shielding sheet 30 has a position corresponding to the light-emitting unit 24. The light outlet 32, whereby the light emitted by the light-emitting unit 24 can be emitted to the keycap 16 through the light outlet 32, so that the key 14 produces a light-emitting effect.

如此一來，透過上述第一支撐件26之遮蔽片30覆蓋於發光單元24上方之設計，本發明係可確保發光單元24所發射之光線僅能經由遮蔽片30之出光口32投射至鍵帽16，從而達到防止按鍵14漏光之功效。除此之外，由於本發明係採用遮蔽片30延伸形成於發光單元24上方之設計以取代先前技術在支撐件上裁切L型讓位槽之設計，因此本發明亦可強化升降支撐裝置之支撐件之整體結構強度以及改善先前技術所提到的鍵帽按壓作動性較差的問題，從而有效地提升按鍵的按壓手感與結構同動性。In this way, through the above-mentioned design that the shielding sheet 30 of the first support 26 covers the top of the light-emitting unit 24, the present invention can ensure that the light emitted by the light-emitting unit 24 can only be projected to the keycap through the light outlet 32 of the shielding sheet 30 16, so as to prevent the key 14 from leaking light. In addition, since the present invention adopts the design in which the shielding sheet 30 is extended and formed above the light-emitting unit 24 to replace the prior art design of cutting the L-shaped relief groove on the support, the present invention can also strengthen the lifting support device The overall structural strength of the support and the improvement of the problem of poor key cap pressing action mentioned in the prior art, so as to effectively improve the pressing feel of the key and the structural synchronization.

值得一提的是，如第2圖以及第3圖所示，在此實施例中，遮蔽片30可往第一支撐件26連接底板12之位置延伸形成有承靠底邊34，藉此，當鍵帽16經由升降支撐裝置20相對於底板12做上下運動使得第一支撐件26相對於底板12樞轉時，承靠底邊34係可抵接於底板12以提供足夠的樞轉支撐力至升降支撐裝置20，從而更進一步地提升按鍵14之按壓手感。另外，為了可確實地避免漏光問題，由第2圖以及第3圖可知，遮蔽片30從出光口32往發光單元24向下延伸形成有至少一擋牆36（於第3圖中顯示三個擋牆36以沿著出光口32周圍之方式形成，但不受此限），擋牆36係可遮擋發光單元24側向射出之光線，進而產生側向擋光功效。It is worth mentioning that, as shown in Figures 2 and 3, in this embodiment, the shielding sheet 30 can extend to the position where the first support 26 is connected to the bottom plate 12 to form a supporting bottom edge 34, thereby, When the keycap 16 moves up and down relative to the bottom plate 12 via the lifting support device 20 so that the first support 26 pivots relative to the bottom plate 12, the supporting bottom edge 34 can abut against the bottom plate 12 to provide sufficient pivotal support. To the lifting support device 20, the pressing feel of the button 14 is further improved. In addition, in order to reliably avoid the problem of light leakage, it can be seen from Figures 2 and 3 that the shielding sheet 30 extends downward from the light outlet 32 to the light emitting unit 24 to form at least one retaining wall 36 (three are shown in Figure 3). The barrier wall 36 is formed along the periphery of the light outlet 32, but is not limited to this), the barrier wall 36 can block the light emitted from the side of the light emitting unit 24, thereby generating a lateral light blocking effect.

在實際應用中，如第1圖所示，按鍵14可另包含透光片38，透光片38係可接合於出光口32中以產生保護功效或是改變發光顏色之功效。舉例來說，透光片38係可為一般常見之透明蓋片以產生遮蓋保護發光單元24之功效；或者是，透光片38係可為允許特定色光通過之有色透光薄片（如紅色透光片），藉以使按鍵14可發出特定色光。除此之外，按鍵14可另包含彈性結構體40，彈性結構體40（如橡膠墊圈（rubber dome））係可穿設於第一支撐件26以及第二支撐件28中，如此一來，當按壓鍵帽16之外力被釋放時，彈性結構體40係可提供回位彈力至鍵帽16，以驅動鍵帽16回位至未按壓位置，從而產生自動回位功效。In practical applications, as shown in FIG. 1, the button 14 may further include a light-transmitting sheet 38, which can be joined in the light outlet 32 to produce a protective effect or change the light-emitting color. For example, the light-transmitting sheet 38 may be a common transparent cover sheet to cover and protect the light-emitting unit 24; or, the light-transmitting sheet 38 may be a colored light-transmitting sheet that allows a specific color of light to pass through (such as a red transparent sheet). Light sheet), so that the button 14 can emit light of a specific color. In addition, the button 14 may further include an elastic structure 40, and the elastic structure 40 (such as a rubber dome) can be inserted through the first support 26 and the second support 28. As a result, When the external force pressing the keycap 16 is released, the elastic structure 40 can provide a return elastic force to the keycap 16 to drive the keycap 16 back to the unpressed position, thereby generating an automatic return function.

需注意的是，發光裝置之配置係可不限於上述實施例，本發明亦可採用發光單元與軟性電路板（Flexible Printed Circuit, FPC）之配置，舉例來說，請參閱第4圖，其為根據本發明另一實施例所提出之鍵盤100之部分剖面示意圖，此實施例與上述實施例所述之元件具有相同編號者，代表其具有相同的結構或功能。如第4圖所示，鍵盤100包含底板12以及複數個按鍵102（於第4圖中僅以一個按鍵102簡示），按鍵102包含鍵帽16、升降支撐裝置20以及發光裝置104，在此實施例中，發光裝置104可包含發光單元24（如發光二極體，但不受此限）以及軟性電路板106，軟性電路板106係貼附於底板12下，底板12對應發光單元24之位置形成有開口108，發光單元24係設置於軟性電路板106上且穿設於開口108中，使得按鍵102經由軟性電路板106進行發光單元24之發光控制，例如控制發光單元24發出閃爍光線或是不同顏色之色光等。至於針對鍵盤100之其他相關描述（如支撐件之結構設計等），其係可參照上述實施例類推，於此不再贅述。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 the configuration of the light-emitting device is not limited to the above-mentioned embodiment.
