Description
本創作關於一種按鍵結構，尤指一種利用彈片提供按壓手感之按鍵結構。The present invention relates to a button structure, and more particularly to a button structure that uses a spring to provide a pressing feel.
於一般鍵盤，觸發按鍵開關多利用鍵帽擠壓橡膠圓突或金屬圓突來實現。橡膠材料相較金屬材料來得軟(或謂彈性係數較小)，欲提供按壓鍵帽相當的反饋力特性(亦即使用者於按壓過程中，施力的大小有明顯的落差手感)，則需增加厚度，則橡膠圓突整體體積亦增加，常用於使用交叉式升降支架的按鍵結構中，此類按鍵結構通常具有較大的按壓行程及容置空間。當橡膠圓突用於較薄的鍵盤中，由於按鍵結構的按壓行程及可提供的容置空間均較小，橡膠圓突難以提供令人滿意的反饋力特性。金屬材料相較橡膠材料來得硬(或謂彈性係數較大)，可於較小的行程及配置空間中保持提供較大的反饋力，故金屬圓突常用於薄形鍵盤，但由於金屬圓突結構(圓盤突出狀)的特性，金屬圓突不適於直接提供高行程的反饋力。此外，結構尺寸些微的差異即足使反饋力產生不小的變化，不利產品製造的控制。金屬圓突經長時間使用而後亦會產生彈性疲乏現象，甚至結構產生部分永久變形，使得可提供的反饋力降低，皆會影響使用者使用者的手感。因此，目前用於觸發按鍵開關的圓突件難以兼顧按壓行程及適當的按壓力特性之需求。In the general keyboard, the trigger button switch is mostly realized by pressing the rubber dome or the metal knob by the key cap. The rubber material is softer than the metal material (or the coefficient of elasticity is small), and it is required to provide a feedback force characteristic of pressing the keycap (that is, the user has a significant drop in the magnitude of the force applied during the pressing process), When the thickness is increased, the overall volume of the rubber dome is also increased, which is commonly used in a button structure using a cross-type lifting bracket, and such a button structure usually has a large pressing stroke and a housing space. When the rubber dome is used in a thin keyboard, the rubber dome is difficult to provide satisfactory feedback force characteristics due to the small press stroke of the button structure and the small accommodation space available. The metal material is harder than the rubber material (or the coefficient of elasticity is larger), and can provide a large feedback force in a small stroke and configuration space, so metal round protrusions are often used for thin keyboards, but due to metal round protrusions The characteristics of the structure (disproportion of the disc), metal rounds are not suitable for directly providing high-stroke feedback force. In addition, the slight difference in the size of the structure is sufficient to cause a small change in the feedback force, which is unfavorable for the control of product manufacture. Metal rounds can also be elastically fatigued after prolonged use, and even the structure is partially deformed, so that the feedback force that can be provided is reduced, which affects the user's hand. Therefore, the presently used knob for triggering the key switch is difficult to achieve both the pressing stroke and the appropriate pressing force characteristics.
鑑於先前技術中的問題，本創作的目的之一在於提供一種按鍵結構，其使用之彈片可兼顧按壓行程及適當的按壓力特性之需求。In view of the problems in the prior art, one of the purposes of the present invention is to provide a button structure in which the shrapnel used can balance the requirements of the pressing stroke and the appropriate pressing force characteristics.
本創作之按鍵結構包含一鍵帽、一底板及一彈片。該底板設置於 該鍵帽之下。該彈片設置於該鍵帽及該底板之間並包含一按壓部及複數個支架。該按壓部具有一周圍，每一支架具有一固定端及一連接端，該固定端固定設置，該連接端連接於該周圍。當該鍵帽被按壓而擠壓該彈片時，該按壓部朝向該底板移動且該支架彈性變形。其中，由於該按壓部之剛性(或謂結構剛性)大於該複數個支架之剛性，故於該彈片被該鍵帽擠壓時，該彈片的變形量絕大部分地由該複數個支架的變形決定。藉此，按壓該彈片的力量大小可透過設計該支架之剛性而獲得控制，可解決習知圓突狀彈片無法兼顧按壓行程及適當的按壓力的困境。另外補充說明的是，實際上，雖然該按壓部受力時亦會產生彈性變形，但可透過結構設計(包含該支架之厚度、結構輪廓等)以使該按壓部之剛性遠大於該複數個支架之剛性，使得於前述該彈片被擠壓變形的過程中，該按壓部的變形量遠小於該複數個支架之變形量；其中，前述剛性的差異可由產品規格、使用環境等因素而決定，不以特定比例或量值差為限。此時，於工程應用上，該按壓部可視為剛體，而該複數個支架則可視為彈性體，提供彈性變形。The key structure of the creation includes a keycap, a bottom plate and a shrapnel. The bottom plate is set to Under the keycap. The elastic piece is disposed between the keycap and the bottom plate and includes a pressing portion and a plurality of brackets. The pressing portion has a circumference, each bracket has a fixed end and a connecting end, and the fixed end is fixedly disposed, and the connecting end is connected to the circumference. When the keycap is pressed to press the elastic piece, the pressing portion moves toward the bottom plate and the bracket is elastically deformed. Wherein, since the rigidity (or structural rigidity) of the pressing portion is greater than the rigidity of the plurality of brackets, when the elastic piece is pressed by the keycap, the deformation amount of the elastic piece is largely deformed by the plurality of brackets. Decide. Thereby, the strength of pressing the elastic piece can be controlled by designing the rigidity of the bracket, which can solve the problem that the conventional rounded elastic piece cannot balance the pressing stroke and the appropriate pressing force. In addition, in fact, although the pressing portion is elastically deformed when subjected to a force, the structural design (including the thickness of the bracket, the structural contour, and the like) may be transmitted such that the rigidity of the pressing portion is much larger than the plurality of The rigidity of the bracket is such that the deformation amount of the pressing portion is much smaller than the deformation amount of the plurality of brackets during the deformation of the elastic piece; wherein the difference in rigidity may be determined by factors such as product specifications and use environment. Not limited to a specific ratio or magnitude difference. At this time, in engineering applications, the pressing portion can be regarded as a rigid body, and the plurality of brackets can be regarded as an elastic body to provide elastic deformation.

請參閱第1圖及第2圖，第1圖為根據本創作之一實施例之按鍵結構1之剖面圖，第2圖為按鍵結構1之彈片16之示意圖。按鍵結構1包含一鍵帽10、一底板12、一升降機構14、一彈片16及一開關18。底板12設置於鍵帽10之下，升降機構14設置於鍵帽10及底板12之間，使得鍵帽10透過升降機構14而能相對於底板12上下移動。彈片16設置於鍵帽10及底板12之間，彈片16包含一按壓部162及複數個支架164，按壓部162位於鍵帽10之下且具有一周圍162a，每一支架164具有一固定端1642、一連接端1644及連接固定端1642與連接端1644之一本體部1646，固定端1642相對於底板12固定設置，連接端1644連接於周圍162a，每一個支架164的本體部1646彼此間均不直接相連。開關18設置於按壓部162之下且正對按壓部162設置於底板12上。當鍵帽10被按壓而向下(即朝向底板12)移動，鍵帽10擠壓彈片16使其彈性變形，變形的彈片16的按壓部162即能觸發開關18；於按壓鍵帽10的外力(即使用者的按壓力)消失後，變形的彈片16即可因之前儲存的彈性變形能釋放而將鍵帽10向上(即背離底板12)反推回去並回復原形。此即完成按鍵結構1的一次按壓操作。Referring to FIG. 1 and FIG. 2, FIG. 1 is a cross-sectional view of a key structure 1 according to an embodiment of the present invention, and FIG. 2 is a schematic view of a spring 16 of the key structure 1. The button structure 1 includes a keycap 10, a bottom plate 12, a lifting mechanism 14, a spring 16 and a switch 18. The bottom plate 12 is disposed under the keycap 10, and the lifting mechanism 14 is disposed between the keycap 10 and the bottom plate 12, so that the keycap 10 can move up and down relative to the bottom plate 12 through the lifting mechanism 14. The elastic piece 16 is disposed between the keycap 10 and the bottom plate 12. The elastic piece 16 includes a pressing portion 162 and a plurality of brackets 164. The pressing portion 162 is located under the keycap 10 and has a circumference 162a. Each bracket 164 has a fixed end 1642. a connecting end 1644 and a connecting fixed end 1642 and a connecting end 1644 body portion 1646, the fixed end 1642 is fixedly disposed with respect to the bottom plate 12, the connecting end 1644 is connected to the surrounding 162a, and the main body portion 1646 of each bracket 164 is not between each other Directly connected. The switch 18 is disposed under the pressing portion 162 and is disposed on the bottom plate 12 opposite to the pressing portion 162. When the keycap 10 is pressed and moved downward (ie, toward the bottom plate 12), the keycap 10 presses the elastic piece 16 to elastically deform, and the pressing portion 162 of the deformed elastic piece 16 can trigger the switch 18; the external force of pressing the keycap 10 After the user's pressing force disappears, the deformed elastic piece 16 can release the keycap 10 upward (ie, away from the bottom plate 12) and return to the original shape due to the release of the elastic deformation stored before. This completes a one-press operation of the key structure 1.
於本實施例中，彈片16共具有四個支架164，相對按壓部162對稱設置，但本創作不以此為限。於實作上，彈片亦可僅採用兩個或三個支架164，同樣是相對於按壓部162對稱設置或謂於周圍162a平均設置，有助於彈片本身於底板12上平穩的設置及增加彈片變形時之結構平衡性，但本創作不以此為限。使用更多數量的支架164亦是可行，不待贅述。另外，於本實施例中，按壓部162呈圓形輪廓，但本創作不以此為限，例如方形、矩形、多邊形或其他幾何形狀亦可適用。此外，於本實施例中，固定端1642係固定銲於底板12上，但本創作不以此為限；例如，將固定端1642卡入形成於底板12上之插槽122(如第1圖中虛線所示者)，亦可達到將固定端1642相對於底板12固定的目的。補充說明的是，前述固定端1642的固定設置非限於相對於底板12完全不動的設置方式，原則上，僅需於彈片16受力變形的過程 中，固定端1642得均保持相對於底板12不動即可；因此，於實作上，因為彈片16下壓時會促使固定端1642向外滑動(相對於按壓部162)，故固定端1642亦可僅藉由固定設置於底板12上之一擋塊結構(例如前述插槽122之自底板12垂直延伸的部分)來防止固定端1642於彈片16受力變形的整個過程中向外滑動，即可達到前述對固定端1642固定設置的要求。In this embodiment, the elastic piece 16 has a total of four brackets 164, which are symmetrically disposed with respect to the pressing portion 162, but the present invention is not limited thereto. In practice, the elastic piece can also adopt only two or three brackets 164, which are also symmetrically arranged with respect to the pressing portion 162 or evenly disposed around the circumference 162a, which helps the elastic piece itself to be smoothly arranged on the bottom plate 12 and increases the elastic piece. Structural balance during deformation, but this creation is not limited to this. It is also feasible to use a larger number of brackets 164 and will not be described again. In addition, in the embodiment, the pressing portion 162 has a circular outline, but the present invention is not limited thereto, and for example, a square, a rectangle, a polygon, or other geometric shapes may also be applicable. In addition, in the embodiment, the fixed end 1642 is fixedly welded to the bottom plate 12, but the present invention is not limited thereto; for example, the fixed end 1642 is snapped into the slot 122 formed on the bottom plate 12 (as shown in FIG. 1). The purpose of fixing the fixed end 1642 relative to the bottom plate 12 can also be achieved by the dotted line. It should be noted that the fixed arrangement of the fixed end 1642 is not limited to the setting manner that is completely immovable with respect to the bottom plate 12. In principle, only the process of the elastic deformation of the elastic piece 16 is required. In this case, the fixed ends 1642 are both kept stationary relative to the bottom plate 12; therefore, in practice, since the elastic piece 16 is pressed to cause the fixed end 1642 to slide outward (relative to the pressing portion 162), the fixed end 1642 is also The fixed end 1642 can be prevented from sliding outward during the whole process of the elastic deformation of the elastic piece 16 by only one of the stopper structures fixed on the bottom plate 12 (for example, the portion of the aforementioned slot 122 extending perpendicularly from the bottom plate 12), that is, The aforementioned requirements for the fixed setting of the fixed end 1642 can be achieved.
請併參閱第3圖，其為按鍵結構1於鍵帽10被按壓後的剖面圖。於根據本創作之彈片16中，按壓部162之剛性大於該複數個支架164整體之剛性，亦即該複數個支架164整體結構上受力時比按壓部162容易產生變形(或產生較較大的變形量)，其受力方向基於按鍵結構1之使用(即按壓鍵帽10)，大致上為向下，經由按壓部162對彈片16施力，底板12對彈片16之反作用力則經由固定端1642施加。於實作上，可設計使按壓部162之剛性遠大於該複數個支架164整體之剛性，使得彈片16受力時，主要由該複數個支架164彈性變形以吸收外力作工，而按壓部162的彈性變形則相對十分微小或可忽略不計。例如，透過結構設計(包含支架164之厚度、結構輪廓等)以使按壓部162之剛性遠大於該複數個支架164整體之剛性，使得於前述彈片16被擠壓變形的過程中，按壓部162的變形量遠小於該複數個支架164之變形量。前述剛性的差異可由產品規格、使用環境等因素而決定，不以特定比例或量值差為限。此時，於工程應用上，按壓部162可視為剛體，而該複數個支架164則可視為彈性體，提供彈性變形。Please refer to FIG. 3, which is a cross-sectional view of the button structure 1 after the keycap 10 is pressed. In the elastic piece 16 according to the present invention, the rigidity of the pressing portion 162 is greater than the rigidity of the plurality of brackets 164 as a whole, that is, the plurality of brackets 164 are more susceptible to deformation (or larger) than the pressing portion 162 when the overall structure is stressed. The amount of deformation is based on the use of the button structure 1 (ie, pressing the keycap 10), substantially downward, and the force is applied to the elastic piece 16 via the pressing portion 162, and the reaction force of the bottom plate 12 against the elastic piece 16 is fixed. End 1642 is applied. In practice, the rigidity of the pressing portion 162 can be designed to be much larger than the rigidity of the plurality of brackets 164. When the elastic piece 16 is stressed, the plurality of brackets 164 are elastically deformed to absorb external force, and the pressing portion 162 is pressed. The elastic deformation is relatively small or negligible. For example, through the structural design (including the thickness of the bracket 164, the structural contour, etc.), the rigidity of the pressing portion 162 is much larger than the rigidity of the plurality of brackets 164 as a whole, so that the pressing portion 162 is in the process of the above-described elastic piece 16 being pressed and deformed. The amount of deformation is much smaller than the amount of deformation of the plurality of brackets 164. The difference in rigidity described above may be determined by factors such as product specifications and use environment, and is not limited to a specific ratio or amount difference. At this time, in engineering applications, the pressing portion 162 can be regarded as a rigid body, and the plurality of brackets 164 can be regarded as an elastic body to provide elastic deformation.
於本實施例中，彈片16為一體成形，例如透過金屬板件衝壓成形，按壓部162與支架164之厚度相等，但本創作不以此為限；例如，彈片16仍為一體成形，但按壓部162的板厚大於支架164之板厚。此外，於實作上，按壓部162亦不以板狀為限，且按壓部162與鍵帽10亦不以平面接觸為限。於本實施例中，於鍵帽10下壓致彈片16變形時，按壓部162保持大致水平地緊抵鍵帽10的底表面並隨鍵帽10下移直至觸發開關18，彈片16的彈性變形由該複數個支架164負擔，故彈片16施加於鍵帽10的反作用力(亦 即使用者按壓鍵帽10時感受的反饋力來源)將主要由該複數個支架164之剛性(或應力-應變關係)而決定。於根據本創作之彈片16中，支架164的變形主要發生在本體部1646，由每一個本體部1646彼此無直接連接，故每一個本體部1646得僅受與其連接的固定端1642及連接端1644的拘束而自由變形；換言之，彈片16可提供之反饋力即可由改變支架164設置數量或設計支架164之結構特性(包含厚度、輪廓、材質等)而獲得控制，尤其是本體部1646之結構特性。於本實施例中，支架164整體為一矩形板件，可透過改變其寬度以進一步控制其剛性，但本創作不以此為限。例如，將支架164的本體部1646形成多處鏤空，可降低其剛性。又例如，於另一實施例中，如第4圖所示，彈片26的支架264為大致於底板12的投影方向(即如第1圖中彈片16於底板12的投影方向)上具有彎曲輪廓2642之板件，且此彎曲輪廓2642具有複數個彎曲部2642a，支架264整體呈S形延伸，此支架264相較於支架164亦具有較低的剛性。又例如，於另一實施例中，如第5圖所示，彈片27的支架274亦為大致於底板12的投影方向上具有彎曲輪廓2742之板件，且此彎曲輪廓2742具有複數個彎曲部2742a，支架274整體亦呈S形延伸，惟主要於縱向延伸(支架274主要於橫向延伸)，但支架274同樣相較於支架164亦具有較低的剛性。另外補充說明的是，於支架164中，其本體部1646本身雖呈直板狀，但於實作上亦可呈微彎曲狀，其凹口朝向底板12，有助於本體部1646彈性變形時的穩定性。In the present embodiment, the elastic piece 16 is integrally formed, for example, by stamping and forming a metal plate member, and the pressing portion 162 is equal to the thickness of the bracket 164, but the present invention is not limited thereto; for example, the elastic piece 16 is still integrally formed, but pressed. The thickness of the portion 162 is greater than the thickness of the bracket 164. Further, in practice, the pressing portion 162 is not limited to the plate shape, and the pressing portion 162 and the keycap 10 are not limited to the planar contact. In the present embodiment, when the elastic cap 16 is deformed under the keycap 10, the pressing portion 162 is kept substantially horizontally pressed against the bottom surface of the keycap 10 and moved down with the keycap 10 until the trigger switch 18 is elastically deformed. The load is applied to the keycap 10 by the plurality of brackets 164 (also That is, the source of the feedback force experienced when the user presses the keycap 10 will be determined primarily by the stiffness (or stress-strain relationship) of the plurality of brackets 164. In the shrapnel 16 according to the present invention, the deformation of the bracket 164 mainly occurs in the main body portion 1646, and each of the main body portions 1646 is not directly connected to each other. Therefore, each of the main body portions 1646 is only supported by the fixed end 1642 and the connecting end 1644. The restraining and free deformation; in other words, the feedback force that the elastic piece 16 can provide can be controlled by changing the number of the brackets 164 or the structural characteristics (including thickness, contour, material, etc.) of the design bracket 164, especially the structural characteristics of the body portion 1646. . In the present embodiment, the bracket 164 is a rectangular plate as a whole, and its rigidity can be further controlled by changing its width, but the present invention is not limited thereto. For example, the body portion 1646 of the bracket 164 is formed in a plurality of hollows to reduce its rigidity. For another example, in another embodiment, as shown in FIG. 4, the bracket 264 of the elastic piece 26 has a curved contour substantially in the projection direction of the bottom plate 12 (ie, the projection direction of the elastic piece 16 in the bottom plate 12 in FIG. 1). The plate of 2642, and the curved profile 2642 has a plurality of curved portions 2642a. The bracket 264 extends in an S-shape as a whole, and the bracket 264 has a lower rigidity than the bracket 164. For another example, in another embodiment, as shown in FIG. 5, the bracket 274 of the elastic piece 27 is also a plate member having a curved contour 2742 substantially in the projection direction of the bottom plate 12, and the curved contour 2742 has a plurality of curved portions. 2742a, the bracket 274 also extends generally in an S-shape, but extends primarily in the longitudinal direction (the bracket 274 extends primarily in the lateral direction), but the bracket 274 also has a lower stiffness than the bracket 164. In addition, in the bracket 164, the main body portion 1646 itself has a straight plate shape, but may be slightly curved in practice, and the recess faces the bottom plate 12 to facilitate the elastic deformation of the body portion 1646. stability.
如前述說明，彈片16之剛性並非主要決定於彈片16的高度，故相較於習知淺碟形的金屬圓突結構，本創作之彈片透過對支架的設計，使得彈片整體結構具有彈性，故本創作之彈片具有剛性容易控制、尺寸設計彈性等優點，進而能解決習知圓突件難以兼顧按壓行程及適當的按壓力特性之困境。此外，彈片的剛性能透過支架的結構、配置設計而輕易控制，有助於降低彈片設置空間對剛性的高度影響，增加彈片製程的可靠度；亦有助於延緩或避免彈片彈性疲乏，進而增加彈片的使用壽命。As described above, the rigidity of the elastic piece 16 is not mainly determined by the height of the elastic piece 16. Therefore, the elastic piece of the present invention has the elasticity of the entire structure of the elastic piece due to the design of the metal dome structure of the conventional shallow dish.

In the present embodiment, the contact area of the keycap 10 and the pressing portion 162 is large enough to enable the center of gravity of the keycap 10 to stably remain in the projection area of the pressing portion 162 during the pressing operation cycle of the button structure 1, and the elastic piece 16 The keycap 10 can be supported on the bottom plate 12 by the pressing portion 162. At this time, in the present embodiment, the elevating mechanism 14 mainly serving as the stabilizing function of the stabilizing keycap 10 is also omitted. In addition, in the embodiment, the switch 18 is a touch switch, which is triggered by the contact of the pressing portion 162, but the present invention is not limited thereto. Please refer to FIG. 6, which is a cross-sectional view of a button structure 3 according to another embodiment. The key structure 3 is substantially the same as the structure of the key structure 1. The same component of the key structure 3 still uses the component symbol of the key structure 1. The description of each component of the key structure 3 can be referred to the related description of the key structure 3, and will not be described again. The button structure 3 is mainly different from the button structure 1 in that the switch 38 of the button structure 3 is realized by the thin film circuit board 39. The switch 38 is mainly composed of two contacts which are disposed opposite each other, and the pressing portion 362 of the elastic piece 36 of the button structure 3 The corresponding switch 38 further includes a protruding portion 3622 which is formed, for example, by stamping the pressing portion 362 or by attaching an additional member to the pressing portion 362. When the elastic piece 36 is pressed by the key cap 10 to move the pressing portion 362 toward the bottom plate 12, the protruding portion 3622 of the pressing portion 362 can press the switch 38 to make contact contact thereof to realize the triggering operation of the switch 38. It should be noted that, in this embodiment, the protruding portion 3622 is a partial protruding structure of the pressing portion 362, but the present invention is not limited thereto; for example, the pressing portion 362 is integrally protruded toward the bottom plate 12, such as forming an arc toward the bottom plate 12. The triggering operation of the aforementioned switch 38 can also be realized.
於前述開關18、38的情形中，按壓部162及突出部3622無需具有導電性，但本創作不以此為限。請參閱第7圖，其為根據另一實施例之按鍵結構5之剖面圖。按鍵結構5與按鍵結構3結構大致相同，按鍵結構5相同之構件仍沿用按鍵結構3之元件符號，按鍵結構5各部件之說明可參閱按鍵結構3之相關說明，不另贅述。按鍵結構5與按鍵結構3主要不同之處在於按鍵結構5之開關58主要由一電路板60實現，開關58主要由在一電路板60上兩個鄰近設置的接點組成，電路板60可為但不限於軟性電路板。因開關58外露，故按鍵結構5之按壓部362之突出部3622需具有導電性，例如 突出部3622材質本身即具導電性，或是於突出部3622上披覆一層導電物質，則突出部3622基材無需為導電材質，藉此，突出部3622均能短路開關58而實現開關58的觸發操作。另外，於本實施例中，若按壓部362本身即有效且可靠地能短路開關58，則突出部3622亦可無需設置。In the case of the aforementioned switches 18 and 38, the pressing portion 162 and the protruding portion 3622 need not be electrically conductive, but the present invention is not limited thereto. Please refer to FIG. 7, which is a cross-sectional view of a button structure 5 according to another embodiment.

The components of the button structure 5 are still used as the component symbols of the button structure 3. The description of the components of the button structure 5 can be referred to the related description of the button structure 3, and will not be further described. The key structure 5 is different from the key structure 3 in that the switch 58 of the key structure 5 is mainly realized by a circuit board 60. The switch 58 is mainly composed of two adjacently disposed contacts on a circuit board 60, and the circuit board 60 can be But not limited to flexible boards. Since the switch 58 is exposed, the protruding portion 3622 of the pressing portion 362 of the button structure 5 needs to have conductivity, for example, The material of the protruding portion 3622 is electrically conductive, or a conductive material is coated on the protruding portion 3622, so that the protruding portion 3622 substrate does not need to be a conductive material, whereby the protruding portion 3622 can short the switch 58 to realize the switch 58. Trigger action. Further, in the present embodiment, if the pressing portion 362 itself can effectively and reliably short the switch 58, the protruding portion 3622 does not need to be provided.
