Description
本發明關於一種按鍵及其鍵盤，尤指一種將緩衝層形成於薄膜電路板與底板之間且避開薄膜開關之按鍵及其鍵盤。 The invention relates to a button and a keyboard thereof, in particular to a button for forming a buffer layer between a film circuit board and a bottom plate and avoiding the membrane switch and a keyboard thereof.
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彈性件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，以驅動鍵帽隨著升降支撐裝置(如剪刀腳機構)之機構作動回復至按壓前之位置。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，此外，彈性件整體結構高度過高亦會造成佔用按鍵內部空間的問題而不利於按鍵薄型化設計。 Generally, the conventional keyboard adopts a pressing design in which the elastic member is disposed between the key cap and the bottom plate, whereby when the key cap is pressed by the user, the elastic member provides elastic restoring force to the key cap to drive the key cap to support the lifting and lowering The mechanism of the device (such as the scissors foot mechanism) is actuated to return to the position before the pressing. Since the elastic member is usually made of rubber, the rubber may have a fatigue condition under long-term use, thereby shortening the service life of the button. In addition, the height of the overall structure of the elastic member is too high, which may cause the problem of occupying the internal space of the button. The button is thin and designed.
目前常見用來解決上述問題的方法係為採用磁吸力以取代彈性件之配置，舉例來說，其係可將二磁性件分別設置在底板與升降支撐裝置之支撐件上，藉此，當鍵帽被外力按壓而導致二磁性件互相遠離時，鍵帽可伴隨升降支撐裝置移動至按壓位置，而當外力釋放時，磁吸力就會吸引二磁性件互相靠近而使得鍵帽伴隨升降支撐裝置移動回未按壓位置。然而，由於上述磁吸設計通常需要搭配觸發件(如形成在按鍵內部元件上之結構凸點)下壓觸發薄膜電路板之開關的按壓觸發配置來產生按壓觸發功效，因此往往會因觸發件直接碰撞 薄膜電路板而造成按壓異音干擾問題，從而影響到使用者在按壓按鍵時的使用感受與操作手感，同時也會容易造成按鍵電路元件的損壞而導致按鍵的使用壽命減短。 At present, a common method for solving the above problem is to adopt a magnetic attraction instead of the elastic member. For example, the two magnetic members can be respectively disposed on the support member of the bottom plate and the lifting support device, thereby When the cap is pressed by an external force to cause the two magnetic members to move away from each other, the key cap can be moved to the pressing position with the lifting support device, and when the external force is released, the magnetic attraction force attracts the two magnetic members to be close to each other, so that the key cap moves with the lifting support device. Back to the unpressed position. However, since the above magnetic design usually needs to be combined with a trigger member (such as a structural bump formed on the internal components of the button) to press the trigger trigger configuration of the switch that triggers the thin film circuit board to generate a press triggering effect, it is often directly caused by the trigger member. collision The thin film circuit board causes the problem of pressing the abnormal sound, thereby affecting the user's feeling of use and the feeling of the operation when the button is pressed, and at the same time, the damage of the key circuit component is easily caused, and the service life of the button is shortened.
因此，本發明的目的之一在於提供一種將緩衝層形成於薄膜電路板與底板之間且避開薄膜開關之按鍵及其鍵盤，以解決上述問題。 Accordingly, it is an object of the present invention to provide a button and a keyboard for forming a buffer layer between a thin film circuit board and a bottom plate and avoiding the membrane switch to solve the above problems.
根據一實施例，本發明之按鍵包含一鍵帽、一底板、一支撐裝置、一薄膜電路板、一緩衝層，以及一觸發件。該支撐裝置設置於該底板以及該鍵帽之間且包含一第一支撐件以及一第二支撐件，該第一支撐件以及該第二支撐件可樞轉地連接於該鍵帽以及該底板以使該鍵帽伴隨該支撐裝置於一未按壓位置與一按壓位置之間移動。該薄膜電路板設置於該底板上且具有至少一薄膜開關。該緩衝層形成於該薄膜電路板面對該底板之一面上且至少部分環設於該至少一薄膜開關之周圍以避開該至少一薄膜開關。該觸發件設置於對應該至少一薄膜開關之位置，用來於該鍵帽被按壓至該按壓位置時下壓觸發該至少一薄膜開關。 According to an embodiment, the button of the present invention comprises a keycap, a bottom plate, a support device, a film circuit board, a buffer layer, and a trigger member. The supporting device is disposed between the bottom plate and the keycap and includes a first supporting member and a second supporting member, the first supporting member and the second supporting member being pivotally coupled to the keycap and the bottom plate The keycap is moved between the unpressed position and a pressed position with the support device. The thin film circuit board is disposed on the bottom plate and has at least one membrane switch. The buffer layer is formed on a surface of the thin film circuit board facing the bottom plate and at least partially disposed around the at least one membrane switch to avoid the at least one membrane switch. The triggering member is disposed at a position corresponding to the at least one membrane switch for pressing the at least one membrane switch when the keycap is pressed to the pressing position.
綜上所述，在上述觸發件觸發薄膜開關的過程中，由於緩衝層係至少部分環設於薄膜開關之周圍，因此，緩衝層係可在觸發件下壓薄膜開關時提供彈性緩衝以吸收因觸發件下壓薄膜開關所帶來的衝擊，藉以確實地解決因觸發件直接碰撞薄膜開關或是因薄膜電路板受力碰撞底板所產生的按壓異音問題，從而大幅地改善使用者在按壓按鍵時的使用感受與操作手感，並且延長按鍵的使用壽命。除此之外，透過緩衝層形成於薄膜電路板以及底板之間的設計，緩衝層亦可在將薄膜電路板配置於底板上的組裝過程中提供適當的表面摩擦力，以發揮防止薄膜電路板與底板之間產生相對滑動的定位防滑功效。另外，由於緩衝層係至少部分環設於薄膜開關之周圍以避開薄膜開關，也就是說，緩 衝層並未設置於薄膜開關正下方，因此，本發明係可確保在薄膜電路板與底板之間所額外配置的緩衝層不會影響到按鍵的按壓行程，以利於按鍵之薄型化設計。 In summary, in the process of triggering the membrane switch by the trigger member, since the buffer layer is at least partially disposed around the membrane switch, the buffer layer can provide elastic buffer to absorb the cause when the trigger member presses the membrane switch. The trigger member presses the impact of the membrane switch to reliably solve the problem of pressing the diaphragm switch caused by the trigger member directly colliding with the membrane switch or the diaphragm of the membrane board, thereby greatly improving the user's pressing of the button The feeling of use and operation feel, and extend the life of the button. In addition, through the design of the buffer layer formed between the thin film circuit board and the bottom plate, the buffer layer can also provide appropriate surface friction during the assembly process of disposing the thin film circuit board on the bottom plate to prevent the thin film circuit board from being formed. A relative sliding anti-slip effect is produced between the bottom plate and the bottom plate. In addition, since the buffer layer is at least partially disposed around the membrane switch to avoid the membrane switch, that is, slow The punch layer is not disposed directly under the membrane switch. Therefore, the present invention ensures that the buffer layer additionally disposed between the membrane circuit board and the bottom plate does not affect the pressing stroke of the button, thereby facilitating the thin design of the button.

On the device (such as a notebook computer), but not limited to this.
本發明所提出之緩衝層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，為求簡化說明，以下係針對其中之一具有緩衝層設計之按鍵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。複數個按鍵14係設置於底板12上且包含鍵帽16、支撐裝置18、薄膜電路板20、緩衝層22，以及觸發件24。支撐裝置18係設置於底板12 以及鍵帽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以及第二支撐件28可樞轉地連接於鍵帽16以及底板12以使鍵帽16伴隨支撐裝置18於未按壓位置與按壓位置之間移動；更詳細地說，在此實施例中，支撐裝置18係可較佳地採用磁吸復位設計(但不受此限，其亦可採用其他常見之按鍵支撐設計，例如剪刀腳支撐設計等)，由第4圖可知，底板12可具有第一磁性件30，第一支撐件26可具有第二磁性件32，第二磁性件32對應第一磁性件30，第一磁性件30以及第二磁性件32的其中之一可為一磁鐵，第一磁性件30以及第二磁性件32的其中另一可為一磁鐵或一導磁性材料(例如，鐵或其它金屬)。於此實施例中，第一磁性件30係可較佳地為磁鐵，第二磁性件32係可較佳地由鐵組成而具有導磁性。在另一實施例中，支撐裝置18可完全由導磁性材料製成，或者是，第一磁性件30與第二磁性件32皆可為磁鐵。 The buffer layer design proposed by the present invention can be applied to at least one of the plurality of buttons 14, the number of which depends on the practical application of the keyboard 10. For the sake of simplicity, the following is for one of the buffer layers. The design of the button 14 is described. As for the structural design of the button 14 of the same design, it can be deduced. A plurality of buttons 14 are disposed on the bottom plate 12 and include a keycap 16, a support device 18, a film circuit board 20, a buffer layer 22, and a trigger member 24. The support device 18 is disposed on the bottom plate 12 And between the keycaps 16 and including a first support member 26 and a second support member 28, the first support member 26 and the second support member 28 are pivotally coupled to the keycap 16 and the bottom plate 12 to support the keycap 16 The device 18 is moved between an unpressed position and a pressed position; more specifically, in this embodiment, the support device 18 is preferably a magnetically reset design (but not limited thereto, and other common The button support design, such as the scissor foot support design, etc., can be seen from FIG. 4, the bottom plate 12 can have a first magnetic member 30, the first support member 26 can have a second magnetic member 32, and the second magnetic member 32 corresponds to the first One of the magnetic member 30, the first magnetic member 30 and the second magnetic member 32 may be a magnet, and the other of the first magnetic member 30 and the second magnetic member 32 may be a magnet or a magnetically conductive material (for example , iron or other metals). In this embodiment, the first magnetic member 30 is preferably a magnet, and the second magnetic member 32 is preferably made of iron and has magnetic permeability. In another embodiment, the support device 18 can be made entirely of a magnetically permeable material, or both the first magnetic member 30 and the second magnetic member 32 can be magnets.
此外，由第3圖以及第4圖可知，薄膜電路板20係設置於底板12上且具有至少一薄膜開關34(於第3圖中顯示一個，但不受此限)，緩衝層22係可較佳地以印刷塗佈或貼附之方式形成於薄膜電路板20面對底板12之一面上且至少部分環設於薄膜開關34之周圍(較佳地採用如第3圖所示之緩衝層22部分環設於薄膜開關34之周圍的設計，但不受此限，其亦可採用緩衝層22完全環繞包圍薄膜開關34之設計)以避開薄膜開關34，其中緩衝層22係可較佳地由橡膠材質所組成，例如使用型號CSNE-A60020與CSNE-B60020之橡膠以1：1比例混合，但不受此限。至於在觸發件24之結構設計方面，如第4圖所示，在此實施例中，觸發件24係可較佳地為從第一支撐件26朝底板20向下延伸形成之觸發凸點，薄膜開關34係可形成於對應觸發凸點之位置。 In addition, as can be seen from FIG. 3 and FIG. 4, the thin film circuit board 20 is disposed on the bottom plate 12 and has at least one membrane switch 34 (one shown in FIG. 3, but not limited thereto), and the buffer layer 22 is Preferably, it is formed by printing coating or attaching on one surface of the thin film circuit board 20 facing the bottom plate 12 and at least partially around the membrane switch 34 (preferably using a buffer layer as shown in FIG. 3) The 22-part ring is disposed around the membrane switch 34, but is not limited thereto, and the buffer layer 22 may be completely surrounded by the membrane switch 34 to avoid the membrane switch 34, wherein the buffer layer 22 is preferably used. The ground is composed of a rubber material, for example, a rubber of the type CSNE-A60020 and CSNE-B60020 is mixed in a 1:1 ratio, but is not limited thereto. As for the structural design of the triggering member 24, as shown in FIG. 4, in this embodiment, the triggering member 24 is preferably a triggering bump formed by extending downward from the first supporting member 26 toward the bottom plate 20. The membrane switch 34 can be formed at a position corresponding to the trigger bump.
透過上述設計，當鍵帽16未被按壓時，第一磁性件區30與第二磁性件32之間的磁吸力使鍵帽16維持於如第4圖所示之未按壓位置。當鍵帽16被外力按壓，且此外力足夠克服磁吸力而導致第二磁性件32與第一磁性件30遠離時，鍵 帽16伴隨支撐裝置18由如第3圖所示之未按壓位置向下移動，於此同時，觸發件24係可隨著第一支撐件26之樞轉下壓觸發薄膜開關34，從而使按鍵14可據以執行使用者所欲輸入之功能。另一方面，當外力釋放時，第一磁性件30與第二磁性件32之間的磁吸力吸引第二磁性件32與第一磁性件30靠近，使得鍵帽16伴隨支撐裝置18移動回如第3圖所示之未按壓位置，從而達到鍵帽自動回位功效。 Through the above design, when the keycap 16 is not pressed, the magnetic attraction between the first magnetic member region 30 and the second magnetic member 32 maintains the keycap 16 in the unpressed position as shown in FIG. When the keycap 16 is pressed by an external force, and further the force is sufficient to overcome the magnetic attraction force causing the second magnetic member 32 to be away from the first magnetic member 30, the key The cap 16 is moved downwardly from the unpressed position as shown in FIG. 3 with the support device 18, and at the same time, the trigger member 24 can be pressed down with the first support member 26 to trigger the membrane switch 34, thereby making the button 14 can perform the function that the user desires to input. On the other hand, when the external force is released, the magnetic attraction between the first magnetic member 30 and the second magnetic member 32 attracts the second magnetic member 32 to approach the first magnetic member 30, so that the keycap 16 moves back with the support device 18 as The unpressed position shown in Fig. 3 achieves the automatic return function of the key cap.
在上述觸發件24觸發薄膜開關34的過程中，由於緩衝層22係部分環設於薄膜開關34之周圍，因此，緩衝層22係可在觸發件24下壓薄膜開關34時提供彈性緩衝以吸收因觸發件24下壓薄膜開關34所帶來的衝擊，藉以確實地解決因觸發件24直接碰撞薄膜開關34或是因薄膜電路板20受力碰撞底板12所產生的按壓異音問題，從而大幅地改善使用者在按壓按鍵時的使用感受與操作手感，並且延長按鍵的使用壽命。除此之外，透過緩衝層22形成於薄膜電路板20以及底板12之間的設計，緩衝層22亦可在將薄膜電路板20配置於底板12上的組裝過程中提供適當的表面摩擦力，以發揮防止薄膜電路板20與底板12之間產生相對滑動的定位防滑功效。另外，由第3圖以及第4圖可知，由於緩衝層22係部分環設於薄膜開關34之周圍以避開薄膜開關34，也就是說，緩衝層22並未設置於薄膜開關34正下方，因此，本發明係可確保在薄膜電路板20與底板12之間所額外配置的緩衝層22不會影響到按鍵14的按壓行程，以利於按鍵14之薄型化設計。 In the process of triggering the membrane switch 34 by the triggering member 24, since the buffer layer 22 is partially looped around the membrane switch 34, the buffer layer 22 can provide elastic buffer to absorb when the membrane switch 34 is pressed under the triggering member 24. Due to the impact of the triggering member 24 pressing the membrane switch 34, the problem of the pressing abnormality caused by the trigger member 24 directly colliding with the membrane switch 34 or the thin film circuit board 20 being forced to collide with the bottom plate 12 is substantially solved. The user feels the feeling of use and the feeling of operation when pressing the button, and prolongs the service life of the button. In addition, the buffer layer 22 can also provide appropriate surface friction during the assembly process of disposing the thin film circuit board 20 on the bottom plate 12 through the design of the buffer layer 22 formed between the thin film circuit board 20 and the bottom plate 12. The anti-slip effect of preventing the relative sliding between the thin film circuit board 20 and the bottom plate 12 is exerted. In addition, as can be seen from FIG. 3 and FIG. 4, since the buffer layer 22 is partially looped around the membrane switch 34 to avoid the membrane switch 34, that is, the buffer layer 22 is not disposed directly below the membrane switch 34. Therefore, the present invention ensures that the buffer layer 22 additionally disposed between the thin film circuit board 20 and the bottom plate 12 does not affect the pressing stroke of the button 14, to facilitate the thin design of the button 14.
值得一提的是，觸發件之結構設計係可不限於上述實施例，藉以提昇本發明所提供之按鍵在觸發件結構上的設計與配置彈性。舉例來說，在另一實施例中，觸發件係可為橡膠彈性體(如橡膠墊圈(rubber dome))且撐抵於鍵帽與底板之間，薄膜開關係可形成於對應橡膠彈性體之位置，藉此，當鍵帽被按壓至按壓位置時，鍵帽係可下壓橡膠彈性體變形以觸發薄膜電路板上之薄膜開關；或者是，在另一實施例中，觸發件係可為從鍵帽朝底板向下延伸形成之觸發凸點，薄膜開關係可形成於對應觸發凸點之位置，藉此，當鍵帽被按壓至 按壓位置時，隨著鍵帽之向下移動，觸發凸點係可下壓觸發薄膜電路板上之薄膜開關。至於針對上述衍生變化實施例之其他相關描述，其係可參照第1圖至第4圖類推，於此不再贅述。 It is to be noted that the structural design of the trigger member is not limited to the above embodiment, so as to enhance the design and configuration flexibility of the button provided by the present invention on the trigger member structure. For example, in another embodiment, the trigger member may be a rubber elastic body (such as a rubber dome) and supported between the key cap and the bottom plate, and the film opening relationship may be formed in the corresponding rubber elastic body. Position, whereby, when the keycap is pressed to the pressing position, the keycap can press the rubber elastic body to deform to trigger the membrane switch on the thin film circuit board; or, in another embodiment, the triggering component can be a triggering bump formed by extending from the keycap toward the bottom plate, and a film opening relationship may be formed at a position corresponding to the triggering bump, whereby when the keycap is pressed to When the position is pressed, as the keycap moves downward, the trigger bump can depress the membrane switch on the trigger film circuit board. For other related descriptions of the above-described derivative variation embodiments, reference may be made to the analogy of FIG. 1 to FIG. 4, and details are not described herein again.
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。 The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
