Description

按鍵及其鍵盤Button and its keyboard

本發明關於一種按鍵及其鍵盤，尤指一種利用支撐件與底板之間的干涉以作為鍵帽復位所需之驅動力之按鍵及其鍵盤。The present invention relates to a button and a keyboard thereof, and more particularly to a button and a keyboard thereof that utilize the interference between the support member and the bottom plate to serve as a driving force for resetting the keycap.

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機構設計係會導致按鍵需要較大的高度空間，因此不利於鍵盤薄型化的應用。此外，由於彈性件通常是橡膠製成，橡膠於長期使用之下會有疲勞狀況，進而使按鍵的使用壽命減短。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 scissor-foot mechanism design adopted by the above-mentioned scissor-foot supporting device causes a large height space of the button, it is disadvantageous for the application of thinning the keyboard. In addition, since the elastic member is usually made of rubber, the rubber has a fatigue condition under long-term use, thereby shortening the service life of the button.

本發明之目的之一在於提供一種利用支撐件與底板之間的干涉以作為鍵帽復位所需之驅動力之按鍵及其鍵盤，以解決上述之問題。SUMMARY OF THE INVENTION One object of the present invention is to provide a button and a keyboard thereof that utilize the interference between the support member and the bottom plate as a driving force for resetting the keycap to solve the above problems.

The joint 18 generates an interference deformation, whereby the key cap 24 can be moved downward from the unpressed position as shown in FIG. 6 to the pivoting of the first support member 28 and the pivoting of the second support member 30 to The pressed position shown in Fig. 8 triggers the switch 41 of the circuit board 40 via the trigger arm 42 to perform the corresponding input function. At the same time, as can be seen from FIGS. 5 and 7 , the first interference portion 20 follows the design of the first support member 28 interfering with the first interference portion 20 at a position corresponding to the first rotation axis L1. A support member 28 is biased relative to the bottom plate 12 by the first support member 28, and is further changed from the abutment state with the first support member 28 as shown in FIG. 5 to the state shown in FIG. a flexural deformation state biased by the first support member 28 to generate an elastic restoring force, and similarly, a design that interferes with the second interference portion 22 at a position corresponding to the second rotation axis L2 through the second support member 30, The two interference portions 22 are biased by the second support member 30 as the second support member 30 pivots relative to the bottom plate 12, and further interfere with the second support member 30 as shown in FIG. The state is changed to a flexural deformation state biased by the second support member 30 as shown in Fig. 7 to generate an elastic restoring force.

另一方面，當上述外力釋放時，受到第一支撐件28偏壓而撓曲變形之第一干涉部20可提供彈性回復力驅動第一支撐件28以第一樞接部16為支點樞轉，且受到第二支撐件30偏壓而撓曲變形之第二干涉部22可提供彈性回復力驅動第二支撐件30以第二樞接部18為支點樞轉，從而帶動鍵帽24從如第7圖所示之按壓位置移動回如第5圖所示之未按壓位置而產生自動回位的功效。On the other hand, when the external force is released, the first interference portion 20 which is biased and deformed by the first support member 28 can provide an elastic restoring force to drive the first support member 28 to pivot with the first pivot portion 16 as a fulcrum. The second interference portion 22, which is flexibly deformed by the second support member 30, can provide an elastic restoring force to drive the second support member 30 to pivot with the second pivot portion 18 as a fulcrum, thereby driving the keycap 24 from The pressing position shown in Fig. 7 is moved back to the unpressed position shown in Fig. 5 to produce an automatic returning effect.

如此一來，在採用支撐件與底板干涉以提供按鍵復位力的設計下，由於第一干涉部20以及第二干涉部22具有較佳的結構彈性而可在受到第一支撐件28以及第二支撐件30偏壓時產生較大程度的干涉變形，因此本發明即可有效地改善鍵盤在組裝各個按鍵時因底板之結構彈性不足所產生之支撐件與底板干涉量變異不一致情況，從而解決各個按鍵之按壓手感差異過大的問題。In this way, under the design that the support member interferes with the bottom plate to provide the button restoring force, the first interference portion 20 and the second interference portion 22 can receive the first support member 28 and the second portion because of the better structural elasticity. When the support member 30 is biased, a large degree of interference deformation occurs. Therefore, the present invention can effectively improve the inconsistency of the interference variation between the support member and the bottom plate caused by insufficient structural elasticity of the bottom plate when assembling the respective keys, thereby solving each The problem that the pressing of the buttons is too different.

值得一提的是，第一干涉部以及第二干涉部之結構設計係可不限於上述實施例，舉例來說，請參閱第9圖、第10圖、第11圖，以及第12圖，第9圖為根據本發明另一實施例所提出之鍵盤100之***示意圖，第10圖為第9圖之鍵盤100之組裝示意圖，第11圖為第10圖之鍵盤100沿剖面線C-C之剖面示意圖，第12圖為第11圖之鍵帽24被按壓至按壓位置之剖面示意圖，其中為了清楚顯示按鍵14之內部機構設計，鍵帽24在第10圖中僅以虛線簡示之，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，其相關描述於此不再贅述。鍵盤100包含底板102以及複數個按鍵14（於第9圖以及第10圖中僅以一個按鍵14簡示之），底板102具有第一樞接部18、第二樞接部20、第一干涉部104，以及第二干涉部106，按鍵14係設置於底板12上且包含鍵帽24以及支撐裝置26，支撐裝置26係設置於底板12以及鍵帽24之間且包含第一支撐件28以及第二支撐件30，第一支撐件28在對應第一轉軸L1之位置上與第一干涉部104干涉（例如，第一支撐件28可自第一轉軸L1往第一干涉部104延伸形成凸塊29（如第9圖所示）以與第一干涉部104干涉，但不受此限），第二支撐件30在對應第二轉軸L2之位置上與第二干涉部106干涉（例如，第二支撐件30可自第二轉軸L2往第二干涉部106延伸形成凸塊31（如第9圖所示）以與第二干涉部106干涉，但不受此限）。更詳細地說，在此實施例中，第一干涉部104係為自底板102朝鍵帽24彎折突出之彎折懸臂而具有較佳的結構彈性且位於第一樞接部18之一側而與第一樞接部18分開獨立設置，第二干涉部106係為自底板102朝鍵帽24彎折突出之彎折懸臂而具有較佳的結構彈性且位於第二樞接部20之一側而與第二樞接部20分開獨立設置，其中第一干涉部104可較佳地垂直於第一轉軸L1以使第一支撐件28可更加確實地偏壓第一干涉部104產生翹曲變形，第二干涉部106可較佳地垂直於第二轉軸L2以使第二支撐件30可更加確實地偏壓第二干涉部106產生翹曲變形，但不受此限。It is to be noted that the structural design of the first interference portion and the second interference portion is not limited to the above embodiment. For example, refer to FIG. 9, FIG. 10, FIG. 11 and FIG. 12, and The figure shows an exploded view of the keyboard 100 according to another embodiment of the present invention. FIG. 10 is a schematic view showing the assembly of the keyboard 100 of FIG. 9. FIG. 11 is a schematic cross-sectional view of the keyboard 100 of FIG. 10 along the section line CC. Fig. 12 is a schematic cross-sectional view showing the keycap 24 of Fig. 11 pressed to the pressing position, wherein in order to clearly show the internal mechanism design of the button 14, the key cap 24 is simply shown by a broken line in Fig. 10, this embodiment is The components described in the above embodiments have the same numbers, and have the same structures or functions, and the related descriptions are not described herein. The keyboard 100 includes a bottom plate 102 and a plurality of buttons 14 (only one button 14 is shown in FIG. 9 and FIG. 10). The bottom plate 102 has a first pivoting portion 18, a second pivoting portion 20, and a first interference. The portion 104 and the second interference portion 106 are disposed on the bottom plate 12 and include a key cap 24 and a supporting device 26 disposed between the bottom plate 12 and the key cap 24 and including the first support member 28 and The second support member 30, the first support member 28 interferes with the first interference portion 104 at a position corresponding to the first rotation axis L1 (for example, the first support member 28 can extend from the first rotation axis L1 to the first interference portion 104 to form a convex portion. The block 29 (as shown in FIG. 9) interferes with the first interference portion 104, but is not limited thereto), and the second support member 30 interferes with the second interference portion 106 at a position corresponding to the second rotation axis L2 (for example, The second support member 30 can extend from the second rotation axis L2 to the second interference portion 106 to form a bump 31 (as shown in FIG. 9 ) to interfere with the second interference portion 106 , but is not limited thereto. In more detail, in this embodiment, the first interference portion 104 is a bent cantilever that protrudes from the bottom plate 102 toward the keycap 24 to have better structural elasticity and is located on one side of the first pivoting portion 18. The first interference portion 106 is separately provided from the first pivoting portion 18 , and the second interference portion 106 is a bent cantilever that protrudes from the bottom plate 102 toward the key cap 24 to have better structural elasticity and is located in one of the second pivoting portions 20 . The side is separately provided separately from the second pivoting portion 20, wherein the first interference portion 104 can be preferably perpendicular to the first rotating shaft L1 such that the first supporting member 28 can more reliably bias the first interference portion 104 to generate warpage. In the deformation, the second interference portion 106 may preferably be perpendicular to the second rotation axis L2 so that the second support member 30 can more reliably bias the second interference portion 106 to generate warping deformation, but is not limited thereto.

透過上述設計，當鍵帽24未被按壓時，第一干涉部104干涉撐抵第一支撐件28且第二干涉部106干涉撐抵第二支撐件30以使鍵帽24維持於如第11圖所示之未按壓位置。當鍵帽24受外力按壓時，由第11圖以及第12圖可知，透過上述第一支撐件28在對應第一轉軸L1之位置上與第一干涉部104干涉的設計，第一干涉部104就會隨著第一支撐件28相對於底板12之樞轉而受到第一支撐件28之偏壓，進而從如第11圖所示之與第一支撐件28干涉之抵接狀態轉變為如第12圖所示之受第一支撐件28偏壓之翹曲變形狀態以產生彈性回復力，同樣地，透過上述第二支撐件30在對應第二轉軸L2之位置上與第二干涉部106干涉的設計，第二干涉部106就會隨著第二支撐件30相對於底板12之樞轉而受到第二支撐件30之偏壓，進而從如第11圖所示之與第二支撐件30干涉之抵接狀態轉變為如第12圖所示之受第二支撐件30偏壓之翹曲變形狀態以產生彈性回復力。另一方面，當上述外力釋放時，受到第一支撐件28偏壓而翹曲變形之第一干涉部104可提供彈性回復力驅動第一支撐件28樞轉，且受到第二支撐件30偏壓而撓曲變形之第二干涉部22可提供彈性回復力驅動第二支撐件30樞轉，從而帶動鍵帽24從如第12圖所示之按壓位置移動回如第11圖所示之未按壓位置而產生自動回位的功效。至於針對第一支撐件28以第一樞接部16為支點相對於第一轉軸L1樞轉與第二支撐件30以第二樞接部18為支點相對於第二轉軸L2樞轉的描述，其係可參照上述實施例，於此不再贅述。Through the above design, when the keycap 24 is not pressed, the first interference portion 104 interferes with the first support member 28 and the second interference portion 106 interferes with the second support member 30 to maintain the keycap 24 as in the eleventh The unpressed position shown in the figure. When the keycap 24 is pressed by an external force, it can be seen from FIGS. 11 and 12 that the first interference portion 104 is transmitted through the first support member 28 at a position corresponding to the first interference portion 104 at a position corresponding to the first rotation portion L1. As the first support member 28 pivots relative to the bottom plate 12, it is biased by the first support member 28, thereby changing from the abutment state with the first support member 28 as shown in FIG. The warp deformation state biased by the first support member 28 shown in FIG. 12 to generate an elastic restoring force, similarly, through the second support member 30 at a position corresponding to the second rotation axis L2 and the second interference portion 106 In the interference design, the second interference portion 106 is biased by the second support member 30 as the second support member 30 pivots relative to the bottom plate 12, and thus from the second support member as shown in FIG. The 30-interference abutment state is changed to a warped deformation state biased by the second support member 30 as shown in Fig. 12 to generate an elastic restoring force. On the other hand, when the external force is released, the first interference portion 104 which is biased and deformed by the first support member 28 can provide an elastic restoring force to drive the first support member 28 to pivot, and is biased by the second support member 30. The second interference portion 22 which is flexibly deformed can provide an elastic restoring force to drive the second support member 30 to pivot, thereby driving the keycap 24 to move back from the pressing position as shown in FIG. Pressing the position produces the effect of automatic return. As for the description of pivoting the first support member 28 with respect to the first pivot portion L1 with the first pivot portion 16 as a fulcrum and the second support member 30 pivoting with respect to the second pivot shaft L2 with the second pivot portion 18 as a fulcrum, Reference may be made to the above embodiments, and details are not described herein again.

如此一來，在採用支撐件與底板干涉以提供按鍵復位力的設計下，由於第一干涉部104以及第二干涉部106具有較佳的結構彈性而可在受到第一支撐件28以及第二支撐件30偏壓時產生較大程度的干涉變形，因此本發明即可有效地改善鍵盤在組裝各個按鍵時因底板之結構彈性不足所產生之支撐件與底板干涉量變異不一致情況，從而解決各個按鍵之按壓手感差異過大的問題。In this way, under the design that the support member interferes with the bottom plate to provide the button restoring force, the first interference portion 104 and the second interference portion 106 can receive the first support member 28 and the second portion because of the better structural elasticity. When the support member 30 is biased, a large degree of interference deformation occurs. Therefore, the present invention can effectively improve the inconsistency of the interference variation between the support member and the bottom plate caused by insufficient structural elasticity of the bottom plate when assembling the respective keys, thereby solving each The problem that the pressing of the buttons is too different.
