Abstract
Description
本創作係關於一種機械式鍵盤，尤其係一種具有回饋裝置之機械式鍵盤。 This creation is about a mechanical keyboard, especially a mechanical keyboard with a feedback device.
隨著現代人生活中電腦的使用率提升，電腦周邊裝置中之鍵盤的需求也跟著提升。而鍵盤係具有複數按鍵，並經由使用者按壓該些按鍵以輸入按鍵訊號或設定指令，並且將該些輸入按鍵訊號或設定指令傳輸給電腦。 With the increase in the use of computers in modern life, the demand for keyboards in computer peripherals has also increased. The keyboard has a plurality of buttons, and the buttons are pressed by the user to input a button signal or a setting command, and the input button signals or setting commands are transmitted to the computer.
當然，現代人除了對鍵盤的使用率逐漸提升外，也開始注重鍵盤使用時的需求，例如：按壓按鍵時的手感，亦即按鍵中之鍵軸的回饋。因此，開始延伸研發機械式鍵盤中各式按鍵的結構，以利於改良按鍵的手感與回饋。 Of course, in addition to the increasing use of the keyboard, modern people have begun to pay attention to the needs of the keyboard, such as the feel of pressing the button, that is, the feedback of the key axis in the button. Therefore, the development of various types of buttons in the mechanical keyboard has been extended to improve the feel and feedback of the buttons.
習知之機械式鍵盤於實際應用上仍有一些問題存在，例如：按鍵中之長鍵，例如：空白鍵，被按壓時因按鍵的結構設計為長條型/長方形，因鍵帽結構較長而使施力點過於集中特定一處，從而造成使用者於按壓時的按壓手感不好，且按鍵回饋的效果亦不佳。 There are still some problems in the practical application of the mechanical keyboard. For example, the long key in the button, for example: blank key, is designed as a long strip/rectangular shape when pressed, because the key cap structure is long. The force application point is concentrated too much in a specific place, so that the user's pressing feeling when pressing is not good, and the effect of button feedback is also poor.
雖然，市面上的機械式鍵盤已增加平衡桿於鍵帽與觸動開關間，以利於平衡桿平均地受力於該觸動開關上，但平衡桿的效果並不如預期，鍵帽與觸動開關間仍因有間隙而使回饋效果不佳。 Although the mechanical keyboard on the market has increased the balance bar between the keycap and the touch switch to facilitate the balance bar to be evenly applied to the touch switch, the balance bar is not as expected, and the key cap and the touch switch remain The feedback effect is poor due to the gap.
再者，設置平衡桿於鍵帽與觸動開關間，按鍵必須額外新增至少一限位件，以使平衡桿限位於兩者之間，由此必須於按鍵中有限的結構空間中新增至少一限位件，此舉必須重新規劃設計按鍵的結構，且更須重新開模重新配置按鍵中的組件結構設計，從而提升非必要的製造成本。 Furthermore, the balance bar is arranged between the key cap and the touch switch, and the button must additionally add at least one limit member so that the balance bar is limited between the two, thereby adding at least a limited structural space in the button. A limit piece, which must re-plan the structure of the design button, and re-open the mold to reconfigure the component structure design in the button, thereby increasing the unnecessary manufacturing cost.
因此，對於現有的機械式鍵盤而言，實仍須設計出一種新穎與回饋效果佳的結構設計，以解決前述習知技術於應用上所產生的缺失。 Therefore, for the existing mechanical keyboard, it is still necessary to design a novel and feedback effect structural design to solve the lack of the prior art application.

The substrate 200 includes a fixing piece 210 and a circuit board. 220, the fixing piece 210 includes an opening 211, the opening 211 includes a first hole 211a, a second hole 211b, and a third hole 211c, and the circuit board 220 includes a plurality of light The first feedback device 310 includes a first auxiliary base 311 and a first elastic member 312, and the second feedback device 320 includes a second auxiliary base 321 and a second elastic member 322, wherein the first auxiliary base 311 and The second auxiliary bases 321 each include a top portion 311a, 321a and a bottom portion 311b, 321b, respectively.
其中，開孔211於其他實施例中亦可為一槽孔，主要用以供觸動開關300、第一回饋裝置310以及第二回饋裝置320穿經並限位於其中。 The opening 211 can also be a slot in other embodiments, and is mainly used for the touch switch 300, the first feedback device 310, and the second feedback device 320 to pass through and be limited thereto.
接續說明上述各元件之連接與作動關係。請再參閱圖2以及圖3，首先說明，第一孔洞211a位於固定片210之中央，而第二孔洞211b以及第三孔洞211c分別位於第一孔洞211a的兩側，觸動開關300、第一輔助基座310以及第二輔助基座321分別穿經並限位於第一孔洞211a、第二孔洞211b以及第三孔洞211c中。 The connection and actuation relationship of the above components will be described in succession. Referring to FIG. 2 and FIG. 3, first, the first hole 211a is located at the center of the fixing piece 210, and the second hole 211b and the third hole 211c are respectively located at two sides of the first hole 211a, and the switch 300 and the first auxiliary are touched. The pedestal 310 and the second auxiliary pedestal 321 respectively pass through and are confined in the first hole 211a, the second hole 211b, and the third hole 211c.
接著，第一彈性件312以及第二彈性件322分別套設於第一輔助基座311之頂部311a以及第二輔助基座321之頂部321a，並再分別對應限位於鍵帽100之內表面100b的第二限位件102以及第三限位件103，且兩彈性件312,322分別彈性地抵頂於內表面100b的兩端，而第一限位件101則對應限位於觸動開關300之頂部300a，舉例來說，前述各元件之頂部300a,311a,321a可設計為一十字形狀的凸塊，而對應該十字形狀的凸塊之三限位件101,102,103，則可對應設計為一十字形狀的凹槽，用以使頂部300a,311a,321a分別限位於三限位件101,102,103。 Then, the first elastic member 312 and the second elastic member 322 are sleeved on the top 311a of the first auxiliary base 311 and the top 321a of the second auxiliary base 321 respectively, and are respectively correspondingly located on the inner surface 100b of the keycap 100. The second limiting member 102 and the third limiting member 103, and the two elastic members 312, 322 are respectively elastically abutted against the two ends of the inner surface 100b, and the first limiting member 101 is correspondingly located at the top 300a of the touch switch 300. For example, the top portions 300a, 311a, 321a of the foregoing components may be designed as a cross-shaped bump, and the three limit members 101, 102, 103 corresponding to the cross-shaped bumps may be correspondingly designed as a cross-shaped concave. The slot is configured to limit the top portions 300a, 311a, 321a to the three limiting members 101, 102, 103, respectively.
另一方面，連桿400連接於第一輔助基座311之底部311b以及第二輔助基座321之底部321b，用以輔助平衡第一回饋裝置310以及第二回饋裝置320間的作用力。 On the other hand, the connecting rod 400 is connected to the bottom 311b of the first auxiliary base 311 and the bottom 321b of the second auxiliary base 321 to assist in balancing the force between the first feedback device 310 and the second feedback device 320.
再者，觸動開關300、第一輔助基座310以及第二輔助基座321再設置於電路板220上，且電路板220因應鍵帽100之外表面100a受外力被觸壓，從而使鍵帽100之內表面100b觸碰觸動開關300之頂部300a，得以使觸動開關300之底部300b接觸電路板220而被電性導通，進而產生一按鍵訊號。其中，由於第一彈性件312以及第二彈性件322同時彈性地抵頂於內表面100b，因此得以使外力均勻地施力於鍵帽100上。 Furthermore, the touch switch 300, the first auxiliary base 310, and the second auxiliary base 321 are further disposed on the circuit board 220, and the circuit board 220 is pressed by the external force of the outer surface 100a of the keycap 100, thereby making the key cap The inner surface 100b of the 100 touches the top 300a of the touch switch 300, so that the bottom 300b of the touch switch 300 contacts the circuit board 220 to be electrically turned on, thereby generating a button signal. Wherein, since the first elastic member 312 and the second elastic member 322 elastically abut against the inner surface 100b at the same time, the external force is uniformly applied to the keycap 100.
當然，不以本例為限制，本例中之限位件主要用以限位或定位彈性件之設置位置，亦可改良限位件之結構設計，藉由彈性件以直接方式或間接方式限位或定位於輔助基座，以使輔助基座或彈性件可彈性抵頂於鍵帽之內表面，從而取代內表面之限位件的設計，且不限制彈性件與輔助基座兩者結合的位置以及結構設計。 Of course, this example is not limited. In this example, the limiting member is mainly used to limit or position the elastic member, and the structural design of the limiting member can be improved. The elastic member is limited in direct or indirect manner. Or positioning the auxiliary base so that the auxiliary base or the elastic member can elastically abut against the inner surface of the key cap, thereby replacing the design of the inner surface of the limiting member, and does not limit the combination of the elastic member and the auxiliary base. The location and structural design.
也就是說，藉由彈性件與輔助基座兩者的組合運用，以使整體回饋裝置可彈性抵頂於鍵帽之內表面，得以平衡鍵帽之受力。 That is to say, by the combination of the elastic member and the auxiliary base, the integral feedback device can elastically abut against the inner surface of the keycap, thereby balancing the force of the keycap.
此外，電路板220更包括複數發光件221，例如：三原色發光二極體(RGB LED)，用以受控於一應用程式，而使該些三原色發光二極體產生單色或多色之光學效果。舉例說明，三原色發光二極體可因應電路板220被電性導通而發光，抑或對應設置位置的配置以及應用程式的設定，從而使機械式鍵盤得以產生色彩漸層或色彩流動的光學效果，例如：色彩流動、閃電或放射狀等光學效果。 In addition, the circuit board 220 further includes a plurality of light-emitting members 221, for example, three primary color light-emitting diodes (RGB LEDs) for controlling an application, and causing the three primary color light-emitting diodes to generate monochromatic or multi-color optics. effect. For example, the three primary color light-emitting diodes can be illuminated according to the electrical conduction of the circuit board 220, or the configuration of the corresponding position and the setting of the application, so that the mechanical keyboard can produce optical effects of color gradient or color flow, for example, : Optical effects such as color flow, lightning or radial.
當然，上述之各元件可為熟悉本技藝之人士進行各種均等的變更或設計，並依據機械式鍵盤於實際運用時的需 求而調整各元件的配置，不應以本實施例為限制。需注意的是，在此實施例及圖式中是以設置有固定片210以及連趕400的方式作實施說明，但於其他的實施方式中亦可不作設。 Of course, the above various components can be variously changed or designed for those skilled in the art, and according to the needs of the mechanical keyboard in practical use. The configuration of each component is adjusted and should not be limited by this embodiment. It should be noted that in this embodiment and the drawings, the method of providing the fixing piece 210 and the connection 400 is described, but it may not be provided in other embodiments.
亦即，本例之機械式鍵盤中的至少一按鍵，亦可直接將觸動開關以及至少一回饋裝置設置於電路板上，再使至少一回饋裝置抵頂於鍵帽之內表面，用以得以平衡鍵帽的受力。 That is, at least one button in the mechanical keyboard of the present example can also directly set the touch switch and the at least one feedback device on the circuit board, and then at least one feedback device is placed on the inner surface of the key cap to enable Balance the force of the keycap.
綜上所述，本案主要藉由具有彈性件之回饋裝置的結構設計以及運用，以使鍵帽得以於有限的空間內，平衡鍵帽受外力的作用力，由此，從而使本案之按鍵具有平衡施受力且穩定回饋力的優點。 In summary, the present invention mainly relies on the structural design and application of the feedback device with elastic members, so that the keycap can be used in a limited space to balance the force of the keycap by the external force, thereby making the button of the present case have Balance the force and stabilize the feedback.
