Description
本發明關於一種按鍵結構,尤指一種利用磁吸力作為回復力之按鍵結構。The present invention relates to a button structure, and more particularly to a button structure that utilizes magnetic attraction as a restoring force.
傳統按鍵結構利用於鍵帽下方設置的彈性構件(例如矽膠圓突),提供鍵帽回復力以直接驅使鍵帽回到原位(即未被按壓時之位置)。為能提供使用者足夠的按壓回饋手感(即使用者按壓時感受之反作用力大小及其變化),此彈性構件通常體積難以縮小,使得此種按鍵結構難以適用於薄形鍵盤中。此外,採用具有相當體積之彈性構件,亦會影響其他構件(例如用於提供鍵帽上下移動之升降機構)之結構強度及穩定度,此問題於薄形鍵盤中將更形嚴重。因此,除非減損或犧牲鍵帽作動的穩定性或按壓回饋手感,否則此種按鍵結構實難以適用於薄形鍵盤中。The conventional button structure utilizes an elastic member (such as a silicone dome) disposed under the keycap to provide a keycap restoring force to directly urge the keycap back to its original position (i.e., the position when it is not pressed). In order to provide the user with sufficient press feedback feel (ie, the magnitude of the reaction force experienced by the user when pressed and its variation), the elastic member is generally difficult to reduce in size, making the button structure difficult to apply to a thin keyboard. In addition, the use of an elastic member having a considerable volume also affects the structural strength and stability of other members, such as an elevating mechanism for providing up and down movement of the keycap. This problem will be more serious in a thin keyboard. Therefore, such a button structure is difficult to apply to a thin keyboard unless the stability of the key cap actuation or the feedback feel is compromised or sacrificed.
鑑於先前技術中的問題,本發明提供一種按鍵結構,利用能透過磁吸力使按鍵結構作動之一支架,用於對鍵帽升降作動之支架提供磁吸力,以作為鍵帽之回復力,使得該按鍵結構無需如傳統矽膠圓突所需之設置、作動空間,亦能提供使用者足夠的按壓回饋手感。In view of the problems in the prior art, the present invention provides a button structure that utilizes a magnetic bracket to actuate a button structure to provide a magnetic attraction for the support of the keycap to act as a restoring force of the keycap. The button structure does not need to be set and operated as required by the conventional silicone round, and can provide sufficient pressing and feedback feeling for the user.
根據本發明之按鍵結構包含一鍵帽、一底座、一第一支架及一第三支架。該第一支架設置於該鍵帽與該底座之間,該第一支架包含一第一磁吸部,該鍵帽支撐於該第一支架並經由該第一支架以相對於該底座上下移動。該第三支架設置於該鍵帽與該底座之間並包含一支撐部及一第二磁吸部,該第三支架以該支撐部支撐於該底座上,該第二磁吸部位於該鍵帽與該第一磁吸部之間且與該第一磁吸部之間產生一磁吸力。其中,當該鍵帽不受外力按壓時,該磁吸力驅使該第一磁吸部與該第二磁吸部靠近,使得該第一支架及該第三支架穩定支撐於該底座上,以及當該鍵帽受一外力按壓而朝向該底座移動時,該第一支架朝向該底座旋轉使得該第一磁吸部與該第二磁吸部相互遠離。於實作上,該磁吸力的大小不必然僅能由相互作用之結構的尺寸大小決定,亦可由結構的材質而決定,故用於產生該磁吸力之結構可僅佔用相對小的空間來設置及作動,此特性有助於避免過度影響該第一支架的結構強度及作動穩定度,故有助於實施在薄形按鍵結構中。又,該磁吸力隨著該二磁吸部間之距離增加而呈非線性的減少,此特性有助於提供使用者明顯的回饋手感。又,該磁吸力可輕易地透過改變該二磁吸部的材質而獲得所需的大小,亦即能提供使用者足夠的回饋力量。The button structure according to the present invention comprises a keycap, a base, a first bracket and a third bracket. The first bracket is disposed between the keycap and the base, and the first bracket includes a first magnetic attraction portion supported by the first bracket and moved up and down relative to the base via the first bracket. The third bracket is disposed between the keycap and the base and includes a support portion and a second magnetic attraction portion. The third bracket is supported on the base by the support portion, and the second magnetic attraction portion is located at the key A magnetic attraction is generated between the cap and the first magnetic attraction and between the first magnetic attraction. Wherein, when the key cap is not pressed by an external force, the magnetic attraction drives the first magnetic attraction portion and the second magnetic attraction portion to be close to each other, so that the first bracket and the third bracket are stably supported on the base, and when When the keycap is pressed against the base by an external force, the first bracket rotates toward the base such that the first magnetic portion and the second magnetic portion are distant from each other. In practice, the magnitude of the magnetic attraction is not necessarily determined only by the size of the interacting structure, but also by the material of the structure, so that the structure for generating the magnetic attraction can occupy only a relatively small space. And actuating, this feature helps to avoid excessively affecting the structural strength and actuation stability of the first bracket, and thus contributes to implementation in a thin button structure. Moreover, the magnetic attraction is non-linearly reduced as the distance between the two magnetic portions increases, and this characteristic helps to provide a user with a significant feedback feel. Moreover, the magnetic attraction can be easily changed to obtain a desired size by changing the material of the two magnetic portions, that is, providing sufficient feedback force for the user.
因此,相較於先前技術,根據本發明之按鍵結構能提供使用者足夠的按壓回饋手感(即使用者按壓時感受之反作用力大小及其變化),且適於薄形設計,故本發明能有效解決先前技術中目前薄形鍵盤設計面臨的兩難問題。Therefore, compared with the prior art, the button structure according to the present invention can provide the user with sufficient press feedback feel (ie, the magnitude of the reaction force felt by the user when pressed and its change), and is suitable for a thin design, so the present invention can Effectively solve the dilemma faced by the current thin keyboard design in the prior art.
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 will be further understood from the following detailed description of the invention.
請參閱圖1至圖3。根據本發明之一實施例之一按鍵結構1包含一鍵帽10、一底座12、一升降機構14及一第三支架16。鍵帽10設置於底座12之上,升降機構14連接於鍵帽10與底座12之間,使得鍵帽10能經由升降機構14以相對於底座12上下移動。第三支架16設置於鍵帽10與底座12之間,第三支架16與升降機構14透過磁吸力互動以提供復位鍵帽10所需之驅動力。藉此,根據本發明之按鍵結構1無需使用傳統的彈性構件(例如矽膠圓突)以提供鍵帽10所需之回復力,升降機構14仍能可獲得相對大的設置空間,有助於升降機構14的結構強度及作動穩定度。Please refer to Figure 1 to Figure 3. According to an embodiment of the invention, the button structure 1 comprises a keycap 10, a base 12, a lifting mechanism 14 and a third bracket 16. The keycap 10 is disposed on the base 12, and the lifting mechanism 14 is coupled between the keycap 10 and the base 12 such that the keycap 10 can be moved up and down relative to the base 12 via the lifting mechanism 14. The third bracket 16 is disposed between the keycap 10 and the base 12, and the third bracket 16 interacts with the lifting mechanism 14 by magnetic attraction to provide a driving force required to reset the keycap 10. Thereby, the button structure 1 according to the present invention does not need to use a conventional elastic member (for example, a rubber dome) to provide the restoring force required for the keycap 10, and the lifting mechanism 14 can still obtain a relatively large installation space, which helps to lift and lower. The structural strength and actuation stability of the mechanism 14.
進一步來說,底座12包含一底板122及疊置於底板122上之一電路板124(例如薄膜電路板),電路板124具有一開關1242(於圖3中以帶影線之虛線圓圈表示)。升降機構14包含一第一支架142及一第二支架144,均設置於鍵帽10與底座12之間。第一支架142之兩端部142a、142b分別可旋轉地連接至鍵帽10之連接部102底板及122之連接部1222,第二支架144兩端部144a、144b分別可旋轉地連接至鍵帽10之連接部104及底板122之連接部1224,第一支架142與第二支架144相互樞接並形成一剪刀結構,故鍵帽10支撐於第一支架142及第二支架144上並經由第一支架142及第二支架144以相對於底座12上下移動。第一支架142包含一第一磁吸部1422。第三支架16包含相互連接的一第二磁吸部162、一支撐部164及一延伸臂166,第三支架16利用第一支架142之通孔142c以使支撐部164向下伸出,使得第三支架16以支撐部164支撐於底座12(或底板122)上,第二磁吸部162位於鍵帽10與第一磁吸部1422之間,延伸臂166位於鍵帽10與第一支架142之間。於本實施例中,第一支架142之架體1420為一塑膠件,第一磁吸部1422為一磁鐵,嵌入架體1420;第三支架16整體以一磁性材料(可為已磁化之材料或可被磁化之材料)製作,故第二磁吸部162與第一磁吸部1422之間能產生磁性互動。於實作上,第一磁吸部1422亦可改為磁性材料製作,而第二磁吸部162改採磁鐵實現,例如第三支架16整體仍以一金屬板件製作本體,並黏附一磁鐵作為第二磁吸部162。此外,前述磁吸部1422、162亦不以單一材質結構為限,複合結構亦可。另外,於本實施例中,第一支架142之端部142b於與連接部1222連接處,沿旋轉軸(即大致相當於第一支架142與連接部1222相對旋轉的軸向)向外延伸一突柱142d,有助於提昇第一支架142相對於連接部1222旋轉之穩定度。Further, the base 12 includes a bottom plate 122 and a circuit board 124 (such as a thin film circuit board) stacked on the bottom plate 122. The circuit board 124 has a switch 1242 (indicated by a dotted circle in FIG. 3) . The lifting mechanism 14 includes a first bracket 142 and a second bracket 144 disposed between the keycap 10 and the base 12. The two ends 142a, 142b of the first bracket 142 are rotatably connected to the bottom plate of the connecting portion 102 of the keycap 10 and the connecting portion 1222 of the second bracket 144, respectively. The two ends 144a, 144b of the second bracket 144 are rotatably connected to the key caps, respectively. The connecting portion 104 of the connecting portion 104 and the connecting portion 1224 of the bottom plate 122, the first bracket 142 and the second bracket 144 are pivotally connected to each other and form a scissor structure, so that the key cap 10 is supported on the first bracket 142 and the second bracket 144 and passes through the first A bracket 142 and a second bracket 144 move up and down relative to the base 12. The first bracket 142 includes a first magnetic attraction portion 1422. The third bracket 16 includes a second magnetic attraction portion 162, a support portion 164 and an extension arm 166 connected to each other. The third bracket 16 utilizes the through hole 142c of the first bracket 142 to extend the support portion 164 downward. The third bracket 16 is supported on the base 12 (or the bottom plate 122) by a support portion 164. The second magnetic attraction portion 162 is located between the keycap 10 and the first magnetic attraction portion 1422. The extension arm 166 is located at the keycap 10 and the first bracket. Between 142. In this embodiment, the frame 1420 of the first bracket 142 is a plastic piece, and the first magnetic portion 1422 is a magnet embedded in the frame 1420; the third frame 16 is entirely made of a magnetic material (which may be a magnetized material). Or a material that can be magnetized, so that a magnetic interaction can be generated between the second magnetic portion 162 and the first magnetic portion 1422. In practice, the first magnetic portion 1422 can also be made of a magnetic material, and the second magnetic portion 162 can be modified by a magnet. For example, the third bracket 16 is still made of a metal plate as a whole, and a magnet is adhered. As the second magnetic attraction portion 162. In addition, the magnetic attraction portions 1422 and 162 are not limited to a single material structure, and the composite structure may be used. In addition, in the embodiment, the end portion 142b of the first bracket 142 extends outward along the rotating shaft (ie, the axial direction substantially corresponding to the relative rotation of the first bracket 142 and the connecting portion 1222) at the connection with the connecting portion 1222. The stud 142d helps to improve the stability of the rotation of the first bracket 142 relative to the connecting portion 1222.
請併參閱圖4至圖6,其中支撐部164隱藏的輪廓以虛線繪示於圖中。於按鍵結構1中,於鍵帽10受一外力F0(以箭頭表示於圖中)按壓而朝向底座12之移動中,鍵帽10自一初始位置(相當於鍵帽10未被按壓時,如圖4所示)、經過一觸發位置(如圖5所示)移動至一按壓位置(如圖6所示)。第二磁吸部162與第一磁吸部1422相對設置並產生一磁吸力F1(以雙箭頭表示於圖中),使得第二磁吸部162與第一磁吸部1422具有相互靠近的趨勢。當鍵帽10不受外力F0按壓時,磁吸力F1驅使第一磁吸部1422與第二磁吸部162靠近,使得鍵帽10自按壓位置、經過觸發位置回復至初始位置且第一支架142及第三支架16穩定支撐於底座12上。雖於本實施例中,第一磁吸部1422與第二磁吸部162因實際的結構配置而未能緊密相互貼合,但磁吸力F1仍足使第一支架142與第三支架16穩定結合。於實作上,亦可透過改變結構配置使得第一磁吸部1422與第二磁吸部162能緊密相貼合,更能提昇第一支架142與第三支架16因磁吸力F1而結合之穩定度。就機構邏輯而言,第一支架142與第三支架16透過第一磁吸部1422與第二磁吸部162的相吸作用而呈現暫時性的固定連接結構,第一支架142以其端部142b連接於底板122,第三支架16以其支撐部164抵接於底板122,故此時第一支架142與第三支架16形成一狀態固定的結構,而能穩定支撐於底座12上。當鍵帽10受外力F0按壓而朝向底座12移動時(例如使用者以手指按壓鍵帽10),第一支架142朝向底座12旋轉使得第一磁吸部1422與第二磁吸部162相互遠離;此時,第一支架142與第三支架16不再是固定連接結構,而是能相對運動的。Please refer to FIG. 4 to FIG. 6 , wherein the hidden contour of the support portion 164 is shown in broken lines in the figure. In the button structure 1, when the keycap 10 is pressed by an external force F0 (indicated by an arrow in the figure) toward the base 12, the keycap 10 is from an initial position (corresponding to when the keycap 10 is not pressed, such as Figure 4) moves through a trigger position (as shown in Figure 5) to a pressed position (as shown in Figure 6). The second magnetic attraction portion 162 is disposed opposite to the first magnetic attraction portion 1422 and generates a magnetic attraction force F1 (indicated by double arrows in the drawing), so that the second magnetic attraction portion 162 and the first magnetic attraction portion 1422 have a tendency to be close to each other. . When the keycap 10 is not pressed by the external force F0, the magnetic attraction force F1 drives the first magnetic attraction portion 1422 to approach the second magnetic attraction portion 162, so that the keycap 10 returns to the initial position from the pressing position, the trigger position, and the first bracket 142. The third bracket 16 is stably supported on the base 12. In the present embodiment, the first magnetic attraction portion 1422 and the second magnetic attraction portion 162 are not closely adhered to each other due to the actual structural configuration, but the magnetic attraction force F1 is still sufficient to stabilize the first bracket 142 and the third bracket 16 Combine. In practice, the first magnetic portion 1422 and the second magnetic portion 162 can be closely adhered to each other by changing the structural configuration, and the first bracket 142 and the third bracket 16 can be combined to be combined by the magnetic attraction force F1. stability. In terms of the mechanism logic, the first bracket 142 and the third bracket 16 transmit a temporary fixed connection structure through the attraction of the first magnetic portion 1422 and the second magnetic portion 162, and the first bracket 142 has an end portion thereof. The 142b is connected to the bottom plate 122, and the third bracket 16 abuts against the bottom plate 122 by the support portion 164. Therefore, the first bracket 142 and the third bracket 16 form a state-fixed structure, and can be stably supported on the base 12. When the keycap 10 is pressed against the base 12 by the external force F0 (for example, the user presses the keycap 10 with a finger), the first bracket 142 is rotated toward the base 12 such that the first magnetic portion 1422 and the second magnetic portion 162 are away from each other. At this time, the first bracket 142 and the third bracket 16 are no longer fixed connection structures, but can move relative to each other.
延伸臂166放置於第一支架142上,延伸臂166具有一觸發部166a,可自第一支架142之一通孔142e向下伸出(即朝向開關1242突出),使得當鍵帽10受外力F0按壓而朝向底座12移動時,觸發部166a能觸發開關1242。於本實施例中,支撐部164抵接底板122,故抵接處可視為第三支架16相對於底板122之旋轉中心,亦即支點(以十字標記表示於圖中)。以延伸臂166、第二磁吸部162及支點於底板122上之投影來看,第二磁吸部162之質心位於延伸臂166之質心與支點之間,故磁吸力F1原則上會驅使支撐部164保持抵接底板122且延伸臂166原則上保持抵靠第一支架142。以圖4至圖6之視角而言,於鍵帽10受外力F0而朝向底板122自初始位置、經過觸發位置移動至按壓位置移動的過程中,第一支架142順時針旋轉,第一磁吸部1422遠離第二磁吸部162。第三支架16受到磁吸力F1的作用而有逆時針旋轉的傾向,於觸發部166a接觸開關1242前,延伸臂166保持接觸第一支架142。當鍵帽10位於觸發位置時,觸發部166a接觸並觸發開關1242。於觸發部166a接觸開關1242後,雖第一支架142持續隨著鍵帽10的向下移動而旋轉,但第三支架16原則上不再旋轉,且延伸臂166與第一支架142分開。於鍵帽10自觸發位置移動至按壓位置,觸發部166a保持接觸開關1242。此外,於鍵帽10自觸發位置至按壓位置移動時,第三支架16原則上不再旋轉,故觸發部166a對開關1242的觸發施力實質上不會增加(忽略磁吸力F1變化對該觸發施力的影響),此可保護開關1242的結構,延長使用壽命。另外,於鍵帽10自初始位置移動至觸發位置時,延伸臂166受到磁吸力F1的作用,接觸並施一力F2(以箭頭表示於圖中)於第一支架142,有助於第一支架142的順時針旋轉。當鍵帽10不受外力F0按壓時(例如使用者手指移離鍵帽10),磁吸力F1驅使第一磁吸部1422與第二磁吸部162靠近,使得第一支架142及第三支架16相接觸並穩定支撐於底座12上(如圖4所示);其中,磁吸力F1驅使第一支架142逆時針旋轉亦同時驅使第三支架16順時針旋轉,使得鍵帽10自按壓位置、經過觸發位置回復至初始位置。The extension arm 166 is placed on the first bracket 142. The extension arm 166 has a triggering portion 166a extending downward from the through hole 142e of the first bracket 142 (ie, protruding toward the switch 1242), so that when the keycap 10 is subjected to an external force F0, The triggering portion 166a can trigger the switch 1242 when pressed against the base 12. In this embodiment, the support portion 164 abuts the bottom plate 122, so the abutment can be regarded as the center of rotation of the third bracket 16 relative to the bottom plate 122, that is, the fulcrum (indicated by a cross mark in the figure). The projection of the extension arm 166, the second magnetic attraction portion 162 and the fulcrum on the bottom plate 122 shows that the center of mass of the second magnetic attraction portion 162 is located between the center of mass and the fulcrum of the extension arm 166, so that the magnetic attraction force F1 is in principle The support portion 164 is urged to remain abutted against the bottom plate 122 and the extension arms 166 are in principle held against the first bracket 142. 4 to FIG. 6 , the first bracket 142 rotates clockwise during the movement of the keycap 10 from the initial position to the pressing position by the external force F0, and the first magnet 142 rotates clockwise, the first magnetic attraction. The portion 1422 is away from the second magnetic attraction portion 162. The third bracket 16 has a tendency to rotate counterclockwise by the action of the magnetic attraction force F1, and the extension arm 166 remains in contact with the first bracket 142 before the trigger portion 166a contacts the switch 1242. When the keycap 10 is in the trigger position, the trigger portion 166a contacts and triggers the switch 1242. After the trigger portion 166a contacts the switch 1242, although the first bracket 142 continues to rotate with the downward movement of the keycap 10, the third bracket 16 does not rotate in principle, and the extension arm 166 is separated from the first bracket 142. When the keycap 10 is moved from the trigger position to the pressed position, the trigger portion 166a holds the contact switch 1242. In addition, when the keycap 10 moves from the trigger position to the pressing position, the third bracket 16 does not rotate in principle, so the triggering force of the trigger portion 166a on the switch 1242 does not substantially increase (ignoring the change of the magnetic force F1 to the trigger) The effect of the force applied), which protects the structure of the switch 1242 and extends the service life. In addition, when the keycap 10 is moved from the initial position to the trigger position, the extension arm 166 is subjected to the magnetic attraction force F1, and a force F2 (shown by an arrow in the figure) is applied to the first bracket 142 to facilitate the first The clockwise rotation of the bracket 142. When the keycap 10 is not pressed by the external force F0 (for example, the user's finger moves away from the keycap 10), the magnetic attraction force F1 drives the first magnetic attraction portion 1422 and the second magnetic attraction portion 162 to be close to each other, so that the first bracket 142 and the third bracket The 16-phase contact and stable support on the base 12 (as shown in FIG. 4); wherein the magnetic force F1 drives the first bracket 142 to rotate counterclockwise and simultaneously drives the third bracket 16 to rotate clockwise, so that the keycap 10 is self-pressing position, Revert to the initial position after the trigger position.
於本實施例中,按鍵結構1於鍵帽10經過觸發位置時,觸發部166a觸發開關1242,故可提供兩階段的按壓操作,增加按鍵結構1輸入的多樣式(例如按鍵結構1另具有一觸發部,用以於鍵帽10位於按壓位置時,觸發電路板124之另一個開關)。但本發明不以此為限。例如透過設計觸發部166a突出第一支架142伸出的長度或開關1242(或觸發部166a)之設置位置,使得觸發位置與按壓位置重合,亦即鍵帽10只有兩種狀態(即被按壓或未被按壓)。In the embodiment, when the key structure 10 passes the trigger position, the triggering portion 166a triggers the switch 1242, so that a two-stage pressing operation can be provided, and the multi-style input of the key structure 1 is increased (for example, the key structure 1 has another one). The triggering portion is configured to trigger another switch of the circuit board 124 when the keycap 10 is in the pressing position. However, the invention is not limited thereto. For example, by designing the triggering portion 166a to protrude the length of the first bracket 142 or the setting position of the switch 1242 (or the triggering portion 166a), the triggering position coincides with the pressing position, that is, the keycap 10 has only two states (ie, being pressed or Not pressed).
請參閱圖7至圖9,其中圖8及圖9之剖面位置相當於圖1中線X-X之位置,且支撐部164隱藏的輪廓以虛線繪示於圖中。按鍵結構3與按鍵結構1結構大致相同,故按鍵結構3沿用按鍵結構1之元件符號,關於按鍵結構3中元件之說明,請亦參閱關於按鍵結構1中相同命名元件之說明。按鍵結構3與按鍵結構1之主要差異在於按鍵結構3之第三支架36不再負擔觸發開關1242的作動,而由按鍵結構3之升降機構34之第一支架342負擔。第一支架342對應開關1242包含一觸發部142f,觸發部142f自架體1420朝向開關1242突出。當鍵帽10受外力F0按壓而朝向底座12移動時,觸發部142f觸發開關1242。於本實施例中,鍵帽10僅具有兩種位置,一是初始位置(即鍵帽10未被按壓時),另一是按壓位置,這也是觸發位置(即鍵帽10被按壓後)。另外,於本實施例中,第三支架36仍保有延伸臂166,故於鍵帽10自初始位置移動至按壓位置(或謂觸發位置)時,延伸臂166受到磁吸力F1的作用,保持接觸並施一力F2(以箭頭表示於圖中)於第一支架342,亦有助於第一支架342的順時針旋轉。Referring to FIGS. 7-9, the cross-sectional positions of FIGS. 8 and 9 correspond to the positions of lines X-X in FIG. 1, and the hidden contours of the support portions 164 are shown in broken lines in the drawings. The button structure 3 is substantially the same as the button structure 1, so that the button structure 3 follows the component symbol of the button structure 1. For the description of the components in the button structure 3, please also refer to the description of the same named component in the button structure 1. The main difference between the button structure 3 and the button structure 1 is that the third bracket 36 of the button structure 3 no longer bears the actuation of the trigger switch 1242, but is borne by the first bracket 342 of the lifting mechanism 34 of the button structure 3. The first bracket 342 corresponding to the switch 1242 includes a trigger portion 142f, and the trigger portion 142f protrudes from the frame body 1420 toward the switch 1242. When the keycap 10 is pressed by the external force F0 to move toward the base 12, the trigger portion 142f triggers the switch 1242. In the present embodiment, the keycap 10 has only two positions, one is the initial position (ie, when the keycap 10 is not pressed), and the other is the pressing position, which is also the trigger position (ie, after the keycap 10 is pressed). In addition, in the embodiment, the third bracket 36 still retains the extension arm 166, so when the keycap 10 moves from the initial position to the pressing position (or the trigger position), the extension arm 166 is subjected to the magnetic attraction force F1 to maintain contact. And applying a force F2 (indicated by an arrow in the figure) to the first bracket 342 also contributes to the clockwise rotation of the first bracket 342.
請參閱圖10至圖12,其中圖11及圖12之剖面位置相當於圖1中線X-X之位置。按鍵結構5與按鍵結構3結構大致相同,故按鍵結構5沿用按鍵結構3之元件符號,關於按鍵結構5中元件之說明,請亦參閱關於按鍵結構3中相同命名元件之說明。按鍵結構5與按鍵結構3之主要差異在於按鍵結構5之第三支架56除了不再負擔觸發開關1242的作動外,也沒有延伸臂166,故按鍵結構5之升降機構54之第一支架542僅與第三支架56之第二磁吸部162互動;其中支撐部564隱藏的輪廓以虛線繪示於圖11及圖12中。同樣的,第三支架56仍可透過第二磁吸部162與第一磁吸部1422間產生的磁吸力F1提供鍵帽10回復力及與第一支架34於鍵帽10未被按壓時於底座12上形成穩定的支撐結構。此外,於本實施例中,第三支架56無需隨著鍵帽10相對於底座12的移動而移動,第三支架56以支撐部564固定於底板122上,其中支撐部564卡於底板122之突柱1226間。但本發明不以此為限,例如第三支架56仍得以可旋轉的方式連接於底板122上,如前述第三支架16、36之支撐部164抵接底板122之情形。Referring to Figures 10 through 12, the cross-sectional positions of Figures 11 and 12 correspond to the positions of lines X-X in Figure 1. The key structure 5 is substantially the same as the key structure 3, so the key structure 5 follows the component symbol of the key structure 3. For the description of the components of the key structure 5, please also refer to the description of the same named component in the key structure 3. The main difference between the button structure 5 and the button structure 3 is that the third bracket 56 of the button structure 5 has no extension arm 166 except for the action of the trigger switch 1242, so the first bracket 542 of the lifting mechanism 54 of the button structure 5 is only The second magnetic attraction portion 162 of the third bracket 56 interacts; wherein the hidden contour of the support portion 564 is shown in broken lines in FIGS. 11 and 12. Similarly, the third bracket 56 can still provide the restoring force of the keycap 10 through the magnetic attraction force F1 generated between the second magnetic attraction portion 162 and the first magnetic attraction portion 1422 and the first bracket 34 when the keycap 10 is not pressed. A stable support structure is formed on the base 12. In addition, in the embodiment, the third bracket 56 does not need to move with the movement of the keycap 10 relative to the base 12, and the third bracket 56 is fixed to the bottom plate 122 by the support portion 564, wherein the support portion 564 is stuck to the bottom plate 122. The stud is between 1226. However, the present invention is not limited thereto. For example, the third bracket 56 is still rotatably coupled to the bottom plate 122, such as the support portion 164 of the third bracket 16, 36 abutting the bottom plate 122.
於前述實施例中,第三支架16、36以支撐部164抵接底板122為例,但本發明不以此為限。原則上,只需第三支架16、36可旋轉地支撐於底座12上,不限於抵接的方式,皆可使得當鍵帽10受外力F0而朝向底座12時,磁吸力F1驅使延伸臂166朝向底座12施力於第一支架142、342。例如樞接,或以容許彈性的彎曲的連接結構或材料連接第三支架16、36與底板122,亦可實現前述可旋轉地連接,進而使第三支架16、36能相對於底座12旋轉。In the foregoing embodiment, the third brackets 16 and 36 are exemplified by the support portion 164 abutting the bottom plate 122, but the invention is not limited thereto. In principle, only the third brackets 16 and 36 are rotatably supported on the base 12, and the abutting manner is not limited thereto, so that when the keycap 10 is subjected to the external force F0 toward the base 12, the magnetic force F1 drives the extension arm 166. The first brackets 142, 342 are urged toward the base 12. For example, pivoting, or connecting the third brackets 16, 36 and the bottom plate 122 with a flexible connecting structure or material, the aforementioned rotatably connected, thereby enabling the third brackets 16, 36 to rotate relative to the base 12.
另外,當第三支架(例如第三支架36、56)無需用於觸發開關1242時,第三支架無需隨著鍵帽10的上下移動而旋轉;換言之,第三支架可採相對於底座12固定設置的方式,例如黏附於底座12(或底板122)、由底板122之一部分向上突出形成第三支架(例如由一金屬板件衝壓成形,同時形成底板122及第三支架56',如圖13所示)。In addition, when the third bracket (for example, the third bracket 36, 56) is not required to be used for the trigger switch 1242, the third bracket does not need to rotate with the up and down movement of the keycap 10; in other words, the third bracket can be fixed relative to the base 12. The manner of setting, for example, adhering to the base 12 (or the bottom plate 122), protrudes upward from a portion of the bottom plate 122 to form a third bracket (for example, stamped and formed by a metal plate member, and simultaneously forms the bottom plate 122 and the third bracket 56', as shown in FIG. Shown).
另外,於前述各實施例中,鍵帽10經由第一支架142及第二支架144水平支撐於底座12上,但本發明不以此為限。於實作上,鍵帽10相對於底座12上下移動不限於水平上下移動,鍵帽10上下擺動亦能相對於底座12具有不同的位置,故邏輯上鍵帽10的上下擺動亦可視包含鍵帽10相對於底座12的上下移動。請參閱圖14至圖16,其中圖14至圖16之剖面位置相當於圖1中線X-X之位置,其中支撐部164隱藏的輪廓以虛線繪示於圖中。按鍵結構7與按鍵結構1結構大致相同,故按鍵結構7沿用按鍵結構1之元件符號,關於按鍵結構7中元件之說明,請亦參閱關於按鍵結構1中相同命名元件之說明。按鍵結構7與按鍵結構1之主要差異在於按鍵結構7僅使用第一支架142作為升降機構,第一支架142之端部142a連接至鍵帽10的一側,鍵帽10的另一側則直接可滑動地放置於底座12上。換言之,鍵帽10支撐於第一支架142並經由第一支架142以相對於底座12上下擺動。於實作上,鍵帽10的另一側可與底座12亦可經由容許鍵帽10相對於底座12旋轉的結構連接。藉此,當鍵帽10受外力F0按壓而自一初始位置(相當於鍵帽10未被按壓時,如圖14所示)、經過一觸發位置(如圖15所示)移動至一按壓位置(如圖16所示)時,鍵帽10的另一側雖在底座12上滑動,鍵帽10仍能具有不同的位置,使得按鍵結構7也能有如按鍵結構1一樣的作動邏輯,並提供兩階段的按壓操作。同樣的,當外力F0自鍵帽10除去後,受到第二磁吸部162與第一磁吸部1422間之磁吸力F1的作用,鍵帽10自按壓位置、經過觸發位置回復至初始位置。In addition, in the foregoing embodiments, the keycap 10 is horizontally supported on the base 12 via the first bracket 142 and the second bracket 144, but the invention is not limited thereto. In practice, the up and down movement of the keycap 10 relative to the base 12 is not limited to horizontal movement up and down, and the keycap 10 can swing up and down to have different positions relative to the base 12, so that the up and down swing of the keycap 10 can also be visually included. 10 moves up and down relative to the base 12. Referring to FIGS. 14-16, the cross-sectional positions of FIGS. 14-16 correspond to the positions of lines X-X of FIG. 1, wherein the hidden outline of the support portion 164 is shown in broken lines in the figure. The button structure 7 is substantially the same as the button structure 1, so that the button structure 7 follows the component symbol of the button structure 1. For the description of the components in the button structure 7, please also refer to the description of the same named component in the button structure 1. The main difference between the button structure 7 and the button structure 1 is that the button structure 7 uses only the first bracket 142 as the lifting mechanism, the end portion 142a of the first bracket 142 is connected to one side of the keycap 10, and the other side of the keycap 10 is directly It is slidably placed on the base 12. In other words, the keycap 10 is supported by the first bracket 142 and swings up and down with respect to the base 12 via the first bracket 142. In practice, the other side of the keycap 10 can be coupled to the base 12 via a structure that permits the keycap 10 to rotate relative to the base 12. Thereby, when the keycap 10 is pressed by the external force F0 and moved from an initial position (corresponding to the keycap 10 is not pressed, as shown in FIG. 14), through a trigger position (as shown in FIG. 15) to a pressing position. (As shown in FIG. 16), while the other side of the keycap 10 slides on the base 12, the keycap 10 can still have different positions, so that the button structure 7 can also have the same actuation logic as the button structure 1, and provide Two-stage pressing operation. Similarly, when the external force F0 is removed from the keycap 10, it is subjected to the magnetic attraction force F1 between the second magnetic attraction portion 162 and the first magnetic attraction portion 1422, and the keycap 10 is returned to the initial position from the pressed position and the triggered position.
於按鍵結構7中,鍵帽10之設置架構亦可應用於前述按鍵結構3、5中,不另贅述。另外,於實作上,根據本發明之升降機構亦可使用單一支架(作為第一支架)並搭配一導引鍵帽垂直移動的結構,亦能產生鍵帽水平上下的運動,例如將按鍵結構7中,以一導槽(固定設置於底座)以導引鍵帽10的另一側於垂直方向的移動。其他可行之實施方式可為習知技藝者基於前述各實施例之說明及習知按鍵結構而可輕易完成,不另贅述。 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。In the button structure 7, the setting structure of the keycap 10 can also be applied to the aforementioned button structures 3, 5, and will not be described again. In addition, in practice, the lifting mechanism according to the present invention can also use a single bracket (as the first bracket) and a structure that vertically moves with a guiding keycap, and can also generate horizontal and vertical movement of the keycap, for example, a button structure. In 7, a guide groove (fixed to the base) is used to guide the movement of the other side of the keycap 10 in the vertical direction. Other possible implementations can be easily accomplished by those skilled in the art based on the description of the foregoing embodiments and the conventional button structure, and are not described again. 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.
