Abstract

A device casing includes a base plate, a keycap, two supports connected to and between the base plate and the keycap, a first magnetic part disposed on one of the supports, a movable plate movably disposed under the base plate, and a second magnetic part disposed correspondingly to the first magnetic part. The first magnetic part and the second magnetic part produce a magnetic attraction force therebetween as a returning force for the keycap. The second magnetic part can be fixed on the movable plate so as to be capable of moving together with the movable plate away from the first magnetic part, so that the magnetic attraction force decreases to facilitate the lowering of the keycap for convenience of storing the keyswitch structure. The movable plate can include a raised portion that can move together with the movable plate to push against one of the supports to rotate toward the base plate, so that the keycap moves toward the base plate for convenience of storing the keyswitch structure.

Description

按鍵結構Button structure

本發明關於一種磁吸式按鍵結構，尤指一種其鍵帽可下沉收納之磁吸式按鍵結構。The present invention relates to a magnetic key structure, in particular to a magnetic key structure whose key cap can be sinked and stored.

傳統鍵盤上的按鍵於未使用時，其鍵帽保持在未被按壓的位置，故傳統鍵盤於非使用狀態時，具有一定的厚度，不利儲藏或搬運。對於筆記型電腦而言，當使用者不需使用筆記型電腦時，使用者會將螢幕合上，由於傳統的按鍵無法收合，因此螢幕有可能與按鍵產生碰撞而受損。又，無法收合之按鍵較佔據空間，造成筆記型電腦薄型化的限制。此外，若按鍵結構採利用彈性構件(例如矽膠圓突)以提供鍵帽回復力之設計時，當鍵帽被強制下沉以便於收納時，彈性構件原則上會長時間處於被壓縮的狀態，可能引起永久便形而影響彈性，不利於彈性構件的使用壽命。When the keys on the traditional keyboard are not in use, the keycaps are kept in the unpressed position. Therefore, when the traditional keyboard is not in use, it has a certain thickness, which is not good for storage or transportation. For a notebook computer, when the user does not need to use the notebook computer, the user closes the screen. Because the traditional buttons cannot be folded, the screen may collide with the buttons and be damaged. In addition, buttons that cannot be folded take up more space, which limits the thinness of notebook computers. In addition, if the key structure uses an elastic member (such as a silicone dome) to provide the keycap restoring force, when the keycap is forced to sink for storage, the elastic member will in principle be in a compressed state for a long time. Causes permanent stool shape and affects elasticity, which is not conducive to the service life of elastic members.

鑑於先前技術中的問題，本發明之一目的在於提供一種按鍵結構，透過拉遠用以產生鍵帽回復力之兩磁吸件的距離，以使鍵帽能下沉以便於收納。In view of the problems in the prior art, one of the objectives of the present invention is to provide a key structure, by extending the distance between the two magnetic attraction members used to generate the key cap restoring force, so that the key cap can sink to facilitate storage.

根據本發明之按鍵結構包含一底板、一鍵帽、一升降機構、一第一磁吸件、一活動板及一第二磁吸件。該鍵帽設置於該底板之上。該升降機構包含一第一支架及與該第一支架樞接之一第二支架。該第一支架及該第二支架個別連接至該底板及該鍵帽之間，使得該鍵帽能透過該第一支架及該第二支架以相對於該底板平行於一垂直方向移動。該第一磁吸件固定設置於該第一支架且突出於該第一支架，該第一磁吸件於該垂直方向上之投影位於該升降機構於該垂直方向上之投影之一側。活動板可滑動地設置於該底板之下。該第二磁吸件對應該第一磁吸件固定設置於該活動板，該第一磁吸件與該第二磁吸件間產生一磁吸力。其中，當該活動板位於一第一位置時，該第二磁吸件位於該第一磁吸件下方，且該磁吸力經由該第一磁吸件及該升降機構驅使該鍵帽遠離該底板移動。又，當該活動板自該第一位置水平滑動至一第二位置時，該第二磁吸件遠離該第一磁吸件及該升降機構，使得該磁吸力下降以使該鍵帽朝向該底板移動。The key structure according to the present invention includes a bottom plate, a key cap, a lifting mechanism, a first magnetic member, a movable plate and a second magnetic member. The key cap is arranged on the bottom plate. The lifting mechanism includes a first bracket and a second bracket pivotally connected to the first bracket. The first bracket and the second bracket are respectively connected between the bottom plate and the key cap, so that the key top can pass through the first bracket and the second bracket to move parallel to the bottom plate in a vertical direction. The first magnetic member is fixedly arranged on the first bracket and protrudes from the first bracket, and the projection of the first magnetic member in the vertical direction is located on one side of the projection of the lifting mechanism in the vertical direction. The movable plate is slidably arranged under the bottom plate. The second magnetic member is fixed on the movable plate corresponding to the first magnetic member, and a magnetic attraction force is generated between the first magnetic member and the second magnetic member. Wherein, when the movable plate is located at a first position, the second magnetic attraction member is located below the first magnetic attraction member, and the magnetic attraction force drives the keycap away from the bottom plate via the first magnetic attraction member and the lifting mechanism mobile. In addition, when the movable plate slides horizontally from the first position to a second position, the second magnetic member is far away from the first magnetic member and the lifting mechanism, so that the magnetic attraction is lowered so that the keycap faces the The bottom plate moves.

本發明之另一目的在於提供一種按鍵結構，透過設置於底板下方的活動板之凸起部，推抵支架以使鍵帽能下沉以便於收納。Another object of the present invention is to provide a key structure, which pushes against the bracket through the protrusion of the movable plate arranged under the bottom plate so that the key cap can sink for easy storage.

根據本發明之按鍵結構包含一底板、一鍵帽、一升降機構、一第一磁吸件、一活動板及一第二磁吸件。該鍵帽設置於該底板之上。該升降機構包含一第一支架及與該第一支架樞接之一第二支架。該第一支架及該第二支架個別連接至該底板及該鍵帽之間，使得該鍵帽能透過該第一支架及該第二支架以相對於該底板平行於一垂直方向移動。該第一磁吸件固定設置且突出於該第一支架及該第二支架其中之一，該第一磁吸件於該垂直方向上之投影位於該升降機構於該垂直方向上之投影之一側。該活動板可滑動地設置於該底板之下且包含一凸起部。該第二磁吸件固定設置於該底板且位於該第一磁吸件下方，該第一磁吸件與該第二磁吸件間產生一磁吸力。其中，當該活動板位於一第一位置時，該磁吸力經由該第一磁吸件及該升降機構驅使該鍵帽遠離該底板移動。又，於該活動板自該第一位置水平滑動至一第二位置的過程中，該凸起部推抵該第一支架以朝向該底板旋轉，使得該鍵帽朝向該底板移動。The key structure according to the present invention includes a bottom plate, a key cap, a lifting mechanism, a first magnetic member, a movable plate and a second magnetic member. The key cap is arranged on the bottom plate. The lifting mechanism includes a first bracket and a second bracket pivotally connected to the first bracket. The first bracket and the second bracket are respectively connected between the bottom plate and the key cap, so that the key top can pass through the first bracket and the second bracket to move parallel to the bottom plate in a vertical direction. The first magnetic member is fixedly arranged and protrudes from one of the first bracket and the second bracket, and the projection of the first magnetic member in the vertical direction is one of the projections of the lifting mechanism in the vertical direction side. The movable plate is slidably arranged under the bottom plate and includes a protrusion. The second magnetic attraction member is fixedly arranged on the bottom plate and located below the first magnetic attraction member, and a magnetic attraction force is generated between the first magnetic attraction member and the second magnetic attraction member. Wherein, when the movable plate is located at a first position, the magnetic attraction force drives the keycap to move away from the bottom plate via the first magnetic attraction member and the lifting mechanism. In addition, during the horizontal sliding of the movable plate from the first position to a second position, the protrusion pushes against the first bracket to rotate toward the bottom plate, so that the keycap moves toward the bottom plate.

相較於先前技術，根據本發明之按鍵結構，其鍵帽即使未受到按壓外力，仍能下沉以便於收納。又，該鍵帽回復力(即該磁吸力)非由彈性結構產生，故不會有先前技術中彈性構件可能永久便形而影響彈性的問題。Compared with the prior art, according to the key structure of the present invention, even if the key cap is not subjected to external pressing force, it can still sink to facilitate storage. In addition, the keycap restoring force (ie, the magnetic attraction force) is not generated by the elastic structure, so there is no problem in the prior art that the elastic member may be permanently deformed and affect the elasticity.

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 can be further understood from the following detailed description of the invention and the accompanying drawings.

請參閱圖1至圖5。根據一實施例之一按鍵結構1包含一底板10、一鍵帽12、一升降機構14、一第一磁吸件16、一觸發件17、一活動板18、一第二磁吸件20及一開關電路板22。鍵帽12設置於底板10之上。升降機構14包含一第一支架142及一第二支架144，個別連接至底板10及鍵帽12之間，使得鍵帽12能透過第一支架142及第二支架144相對於底板10平行於一垂直方向D1 (以雙箭頭標示於圖4及圖5中)於一未按壓位置(如圖4所示者)及一按壓位置(如圖5所示者)移動。第一磁吸件16固定設置於第一支架142且突出於第一支架142。如圖3及圖4所示，第一磁吸件16於垂直方向D1上之投影(於圖3中部分的隱藏輪廓以虛線繪示)位於升降機構14於垂直方向D1上之投影(相當於其於圖3所示之廓輪)之一側。觸發件17設置於第一支架142上。活動板18可滑動地設置於底板10之下。第二磁吸件20對應第一磁吸件16固定設置於活動板18，第一磁吸件16與第二磁吸件20間產生一磁吸力F (以雙箭頭表示於圖4及圖5中)。開關電路板22設置於活動板18上並隨著活動板18一起移動，例如透過黏貼於活動板18上，又或與活動板18間產生結構干涉。開關電路板22具有一開關222 (以帶斜線的圓圈表示於圖2中，並以方塊表示於圖4及圖5中)，對應觸發件17設置。Please refer to Figure 1 to Figure 5. According to an embodiment, a key structure 1 includes a bottom plate 10, a key cap 12, a lifting mechanism 14, a first magnetic member 16, a trigger member 17, a movable plate 18, a second magnetic member 20, and A switch circuit board 22. The key cap 12 is arranged on the bottom plate 10. The lifting mechanism 14 includes a first bracket 142 and a second bracket 144, which are respectively connected between the bottom plate 10 and the keycap 12, so that the keycap 12 can pass through the first bracket 142 and the second bracket 144 to be parallel to the bottom plate 10 The vertical direction D1 (marked with double arrows in FIGS. 4 and 5) moves at an unpressed position (as shown in FIG. 4) and a pressed position (as shown in FIG. 5). The first magnetic member 16 is fixedly disposed on the first bracket 142 and protrudes from the first bracket 142. As shown in FIGS. 3 and 4, the projection of the first magnetic attraction member 16 in the vertical direction D1 (the hidden outline in FIG. 3 is shown in dashed lines) is located in the projection of the lifting mechanism 14 in the vertical direction D1 (equivalent to It is on one side of the profile wheel shown in Figure 3). The trigger 17 is disposed on the first bracket 142. The movable plate 18 is slidably disposed under the bottom plate 10. The second magnetic attraction member 20 is fixedly arranged on the movable plate 18 corresponding to the first magnetic attraction member 16. A magnetic attraction force F is generated between the first magnetic attraction member 16 and the second magnetic attraction member 20 (shown by the double arrow in FIGS. 4 and 5 in). The switch circuit board 22 is disposed on the movable plate 18 and moves together with the movable plate 18, for example, by sticking to the movable plate 18 or causing structural interference with the movable plate 18. The switch circuit board 22 has a switch 222 (represented in FIG. 2 by a circle with a diagonal line, and shown in FIG. 4 and FIG. 5 by a square), which is provided corresponding to the trigger 17.

於本實施例中，第一支架142以一上端部1422與鍵帽12連接且以一下端部1424與底板10連接。第二支架144以一上端部1442與鍵帽12連接且以一下端部1444與底板10連接。第一支架142及第二支架144以一樞接軸A1 (以鏈線長示於圖3中，以十字標記表示於圖4及圖5中)相互樞接。第一磁吸件16及樞接軸A1位於第一支架142連接至底板10處之兩側，使得磁吸力F驅使第一支架142逆時針旋轉(以圖4或圖5之視角)，進而帶動第二支架144旋轉以使鍵帽12向上移動。藉此，當鍵帽12未被按壓時，鍵帽12能位於該未按壓位置(如圖4所示者)。當鍵帽12被外力按壓以朝向底板10移動至該按壓位置時(如圖5所示者)，第一磁吸件16遠離第二磁吸件20，觸發件17隨著第一支架142朝向底板10而旋轉以觸發開關222。當外力移除時，磁吸力F即可作為鍵帽12的回復力，經由第一磁吸件16及升降機構14驅使鍵帽12遠離底板10移動(以回到原位，即如圖4所示未被按壓時之位置)。此外，於本實施例中，開關電路板22可由但不限於習知三層結構的薄膜電路板(其上下層上載有開關電路，中間層絕緣上下層的電路)實作。例如開關電路板22亦得以一印刷電路板或軟板實作，其上焊接一觸碰開關(作為開關222)。In this embodiment, the first bracket 142 is connected to the keycap 12 with an upper end 1422 and is connected to the bottom plate 10 with a lower end 1424. The second bracket 144 is connected to the key cap 12 with an upper end 1442 and is connected to the bottom plate 10 with a lower end 1444. The first bracket 142 and the second bracket 144 are pivotally connected to each other by a pivot axis A1 (shown in FIG. 3 with a chain length, and shown in FIGS. 4 and 5 with a cross mark). The first magnetic member 16 and the pivot axis A1 are located on both sides of the first bracket 142 connected to the bottom plate 10, so that the magnetic attraction F drives the first bracket 142 to rotate counterclockwise (from the perspective of FIG. 4 or FIG. 5), thereby driving The second bracket 144 rotates to move the keycap 12 upward. Thereby, when the keycap 12 is not pressed, the keycap 12 can be located at the unpressed position (as shown in FIG. 4). When the keycap 12 is pressed by an external force to move to the pressing position toward the bottom plate 10 (as shown in FIG. 5), the first magnetic member 16 is away from the second magnetic member 20, and the trigger member 17 faces the first bracket 142 The bottom plate 10 rotates to trigger the switch 222. When the external force is removed, the magnetic attraction F can be used as the restoring force of the keycap 12, and the keycap 12 is driven to move away from the bottom plate 10 through the first magnetic attraction 16 and the lifting mechanism 14 (to return to the original position, as shown in Figure 4 Shows the position when not pressed). In addition, in this embodiment, the switch circuit board 22 can be implemented by, but is not limited to, a conventional three-layer structure thin film circuit board (the upper and lower layers carry the switch circuit, and the middle layer insulates the upper and lower layers). For example, the switch circuit board 22 can also be implemented as a printed circuit board or a soft board, on which a touch switch (as the switch 222) is soldered.

於本實施例中，觸發件17與第一磁吸件16以一順磁性材料一體成形，例如以一金屬板件衝壓成形，此衝壓件(其隱藏輪廓於圖2中虛線繪示)再以埋入射出的方式與第一支架142一體成形。第二磁吸件20為一磁鐵，以與第一磁吸件16間能該磁吸力F。觸發件17呈一懸臂結構，朝向升降機構14內側延伸，其自由端具有朝向底板10的突起17a，用以觸發開關222。呈懸臂結構之觸發件17原則上具有彈性，能避免開關222承受過大的觸發力，有助於延長開關222的使用壽命。此外，於實作上，觸發件17與第一磁吸件16不以同一結構件實作為限。例如觸發件17為獨立於第一磁吸件16之懸臂結構，對應開關222固定於第一支架142或第二支架144上。又例如，觸發件17為第一支架142或第二支架144上朝向開關222突出的部分結構。In this embodiment, the trigger element 17 and the first magnetic element 16 are integrally formed with a paramagnetic material, for example, a sheet metal part is stamped and formed, and the stamping part (its hidden outline is shown in dashed line in FIG. 2) The embedding and exiting method is integrally formed with the first bracket 142. The second magnetic attraction member 20 is a magnet to generate the magnetic attraction force F between the second magnetic attraction member 16 and the first magnetic attraction member 16. The trigger member 17 is a cantilever structure extending toward the inner side of the lifting mechanism 14, and its free end has a protrusion 17 a toward the bottom plate 10 for triggering the switch 222. The trigger member 17 in the cantilever structure is elastic in principle, which can prevent the switch 222 from being subjected to excessive triggering force and help prolong the service life of the switch 222. In addition, in practice, the trigger member 17 and the first magnetic attraction member 16 are not limited to the same structural member. For example, the trigger member 17 is a cantilever structure independent of the first magnetic attraction member 16, and the corresponding switch 222 is fixed on the first bracket 142 or the second bracket 144. For another example, the trigger member 17 is a part of the structure protruding toward the switch 222 on the first bracket 142 or the second bracket 144.

請亦參閱圖6。於本實施例中，活動板18能平行於一水平方向D2 (以雙箭頭標示於圖4至圖6中)相對於底板10滑動以位於一第一位置(如圖4及圖5所示者)或一第二位置(如圖6所示者)。當活動板18位於該第一位置時，第二磁吸件20位於第一磁吸件16下方，開關222亦位於觸發件17的突起17a下方。此時，按鍵結構1處於使用狀態，使用者可操作按鍵結構1 (即按壓鍵帽12、觸發開關222，以實現輸入操作)，如圖4及圖5所示及其相關說明。當活動板18自該第一位置水平滑動至該第二位置時，第二磁吸件20遠離第一磁吸件16及升降機構14，使得磁吸力F下降以使鍵帽12朝向底板10移動。此時，按鍵結構1整體高度減少，便於收納；換言之，按鍵結構1處於收納狀態。於實作上，可透過設計活動板18位於該第二位置時之磁吸力F之量值，使得鍵帽12及升降機構14在自重的作用下自動收折而使按鍵結構1處於收納狀態。此外，當活動板18位於該第二位置時，開關電路板22亦隨著活動板18而移動，使得開關222偏離觸發件17的突起17a，故於按鍵結構1處於收納狀態時，雖然觸發件17亦旋向底板10，觸發件17的突起17a仍不會觸碰到開關222，故開關222未被觸發，此結構設計可避免開關222被長時間按壓。Please also refer to Figure 6. In this embodiment, the movable plate 18 can slide parallel to a horizontal direction D2 (marked by double arrows in FIGS. 4 to 6) relative to the bottom plate 10 to be located at a first position (as shown in FIGS. 4 and 5) ) Or a second position (as shown in Figure 6). When the movable plate 18 is located at the first position, the second magnetic attraction member 20 is located below the first magnetic attraction member 16, and the switch 222 is also located below the protrusion 17 a of the trigger member 17. At this time, the key structure 1 is in use, and the user can operate the key structure 1 (that is, press the keycap 12 and the trigger switch 222 to implement input operations), as shown in FIGS. 4 and 5 and related descriptions. When the movable plate 18 slides horizontally from the first position to the second position, the second magnetic attraction member 20 is away from the first magnetic attraction member 16 and the lifting mechanism 14, so that the magnetic attraction force F is lowered to move the keycap 12 toward the bottom plate 10 . At this time, the overall height of the key structure 1 is reduced to facilitate storage; in other words, the key structure 1 is in a storage state. In practice, by designing the magnitude of the magnetic attraction F when the movable plate 18 is in the second position, the keycap 12 and the lifting mechanism 14 can be automatically folded under the action of their own weight, so that the key structure 1 is in the stored state. In addition, when the movable plate 18 is in the second position, the switch circuit board 22 also moves along with the movable plate 18, causing the switch 222 to deviate from the protrusion 17a of the trigger member 17, so when the key structure 1 is in the storage state, although the trigger member 17 is also rotated to the bottom plate 10, and the protrusion 17a of the trigger member 17 still does not touch the switch 222, so the switch 222 is not triggered. This structural design can prevent the switch 222 from being pressed for a long time.

於本實施例中，按鍵結構1還包含其他互動結構以利於按鍵結構1處於收納狀態。其中，第二支架144包含一滑槽146，沿一延伸方向144a (以一箭頭表示於圖2中)延伸，延伸方向144a由下端部1444指向上端部1442。活動板18包含一滑勾182，對應滑槽146。請參閱圖1、圖2及圖7。於活動板18自該第一位置(如圖1所示者)滑動至該第二位置(如圖7所示者)的過程中，滑勾182於滑槽146內滑動並對滑槽146施力以使第二支架144朝向底板10旋轉，亦有助於使按鍵結構1處於收納狀態。此外，於此過程中，因磁吸力F的下降亦有助於減少滑勾182於滑槽146內滑動之阻力。因此，磁吸力F的下降與滑勾182於滑槽146內之滑動均有助於使按鍵結構1處於收納狀態。此外，於本實施例中，滑槽146包含一開口1462及一槽道1464。於活動板18自該第一位置滑動至該第二位置的過程中，滑勾182自開口1462滑入槽道1464。槽道1464具有一槽底面1464a，槽底面1464a沿朝向鍵帽12偏離延伸方向144a之一方向延伸。於活動板18自該第一位置滑動至該第二位置的過程中，滑勾182滑動於槽底面1464a上。In this embodiment, the key structure 1 further includes other interactive structures to facilitate the key structure 1 in the storage state. The second bracket 144 includes a sliding groove 146 extending along an extension direction 144 a (shown as an arrow in FIG. 2 ), and the extension direction 144 a is directed from the lower end 1444 to the upper end 1442. The movable board 18 includes a sliding hook 182 corresponding to the sliding groove 146. Please refer to Figure 1, Figure 2 and Figure 7. During the sliding of the movable plate 18 from the first position (as shown in FIG. 1) to the second position (as shown in FIG. 7), the sliding hook 182 slides in the sliding groove 146 and applies the sliding groove 146 The force to rotate the second bracket 144 toward the bottom plate 10 also helps to keep the key structure 1 in the stored state. In addition, in this process, the decrease of the magnetic attraction force F also helps to reduce the resistance of the sliding hook 182 sliding in the sliding groove 146. Therefore, the decrease of the magnetic attraction force F and the sliding of the sliding hook 182 in the sliding groove 146 both help to keep the key structure 1 in the stored state. In addition, in this embodiment, the sliding groove 146 includes an opening 1462 and a channel 1464. When the movable plate 18 slides from the first position to the second position, the sliding hook 182 slides into the channel 1464 from the opening 1462. The channel 1464 has a groove bottom surface 1464 a, and the groove bottom surface 1464 a extends in a direction that deviates from the extension direction 144 a toward the key cap 12. When the movable plate 18 slides from the first position to the second position, the sliding hook 182 slides on the groove bottom surface 1464a.

此外，於本實施例中，活動板18得由但不限於一衝壓件實作，滑勾182自活動板18本體朝向鍵帽12延伸彎折形成並穿過底板10，第二磁吸件20固定設置於活動板18相對的限位部184間，於實作上第二磁吸件20可輔以固定於活動板18底面之一薄片件24(例如麥拉片，以虛線繪示於圖2中)固定。此外，於本實施例中，按鍵結構1於第二支架144兩側均設置有滑槽146及對應的滑勾182，此有助於滑勾182對第二支架144對稱施力，可使升降機構14朝向底板10平順疊合。In addition, in this embodiment, the movable plate 18 may be implemented by, but not limited to, a stamping part. The sliding hook 182 extends from the body of the movable plate 18 toward the keycap 12 and is formed by bending and passing through the bottom plate 10. The second magnetic attraction member 20 It is fixedly arranged between the opposite limit parts 184 of the movable plate 18. In practice, the second magnetic attraction member 20 can be supplemented by a thin piece 24 (such as a Mylar sheet) fixed on the bottom surface of the movable plate 18, which is shown in dotted lines in the figure. 2) Fixed. In addition, in this embodiment, the key structure 1 is provided with sliding grooves 146 and corresponding sliding hooks 182 on both sides of the second bracket 144, which helps the sliding hooks 182 to symmetrically apply force to the second bracket 144, so that the lifting The mechanism 14 is smoothly overlapped toward the bottom plate 10.

請參閱圖8至圖10，於其所示之另一實施例中，一按鍵結構2相對於按鍵結構1以其他互動結構，撘配會隨活動板18一起活動的第二磁吸件20，以利於按鍵結構1處於收納狀態。為簡化說明，按鍵結構2與按鍵結構1結構相似，按鍵結構2沿用按鍵結構1之元件符號，關於按鍵結構2之其他說明，請逕參閱按鍵結構1之相關說明，不再贅述。按鍵結構2之活動板18包含一凸起部186。於活動板18自該第一位置(如圖9所示者)水平滑動(即平行於水平方向D2滑動)至該第二位置(如圖10所示者)的過程中，凸起部186推抵第一支架142以使第一支架142朝向底板10旋轉。其中，第一支架142的下端部1424以一旋轉軸向1424a (以十字標記表示於圖9及圖10中)相對於底板10旋轉。以圖9及圖10之視角而言，凸起部186推抵第一支架142的下端部1444之處與樞接軸A1位於旋轉軸向1424a兩側，凸起部186推抵第一支架142的下端部1444以使第一支架142順時針旋轉。Please refer to FIGS. 8-10. In another embodiment shown therein, a key structure 2 has another interactive structure with respect to the key structure 1, and is fitted with a second magnetic attraction member 20 that moves along with the movable plate 18. In order to facilitate the key structure 1 in the storage state. To simplify the description, the key structure 2 is similar in structure to the key structure 1, and the key structure 2 uses the component symbols of the key structure 1. For other descriptions of the key structure 2, please refer to the relevant description of the key structure 1, and will not be repeated. The movable plate 18 of the key structure 2 includes a protrusion 186.

In addition, in the foregoing embodiment, the first bracket 142 is an inner ring bracket, the second bracket 144 is an outer ring bracket, and the first bracket 142 is pivotally connected to the inner side of the second bracket 144, but this is not the case in practice. limit.

請參閱圖11至圖13。根據另一實施例之一按鍵結構3與按鍵結構1結構相似，為簡化說明，按鍵結構3原則上沿用按鍵結構1之元件符號，關於按鍵結構3之其他說明，請逕參閱按鍵結構1之相關說明，不另贅述。於按鍵結構3中，第二磁吸件20固定設置於底板10且位於第一磁吸件16下方，第一磁吸件16與第二磁吸件20間產生一磁吸力F (以雙箭頭表示於圖12及圖13中)。其中，第二磁吸件20固定設置於底板10相對的限位部102間，於實作上可輔以固定於底板10底面之一薄片件24(例如麥拉片，以虛線繪示於圖11中)固定。Please refer to Figure 11 to Figure 13. According to another embodiment, the key structure 3 is similar to the key structure 1. To simplify the description, the key structure 3 uses the component symbols of the key structure 1 in principle. For other descriptions of the key structure 3, please refer to the related key structure 1 Description, no further details. In the key structure 3, the second magnetic attraction member 20 is fixedly arranged on the bottom plate 10 and is located under the first magnetic attraction member 16. A magnetic attraction force F is generated between the first magnetic attraction member 16 and the second magnetic attraction member 20 (with a double arrow Shown in Figure 12 and Figure 13). Wherein, the second magnetic attraction member 20 is fixedly disposed between the opposite limit portions 102 of the bottom plate 10, and can be supplemented by a thin piece 24 (such as a Mylar sheet) fixed on the bottom surface of the bottom plate 10 in practice. 11) Fixed.

如圖12所示者，活動板18位於一第一位置，按鍵結構1處於使用狀態，使用者可透過按壓鍵帽12以觸發開關222，其作動細節如前文所述，不另贅述；其中，磁吸力F經由第一磁吸件16及升降機構14驅使鍵帽12遠離底板10移動。於活動板18自該第一位置(如圖12所示者)水平滑動至一第二位置(如圖13所示者)的過程中，活動板18之凸起部186推抵第一支架142以使第一支架142朝向底板10旋轉，使得鍵帽12朝向底板10移動，以使按鍵結構1整體高度減少，便於收納；換言之，按鍵結構1處於收納狀態(如圖13所示者)。其中，雖然於此過程中，第一磁吸件16與第二磁吸件20間之水平相對位置不變，但於實作上，凸起部186推抵第一支架142之力(例如由使用者經由拉動或推動活動板18施加)仍可克服磁吸力F，因此，第一支架142邏輯上仍能經由凸起部186的推抵而旋轉。As shown in FIG. 12, the movable plate 18 is in a first position, and the key structure 1 is in use. The user can press the key cap 12 to trigger the switch 222. The operation details are as described above and will not be repeated; wherein, The magnetic attraction force F drives the keycap 12 to move away from the bottom plate 10 via the first magnetic attraction member 16 and the lifting mechanism 14. During the horizontal sliding of the movable plate 18 from the first position (as shown in FIG. 12) to a second position (as shown in FIG. 13), the protrusion 186 of the movable plate 18 pushes against the first bracket 142 The first bracket 142 is rotated toward the bottom plate 10, so that the keycap 12 moves toward the bottom plate 10, so that the overall height of the key structure 1 is reduced, which is convenient for storage; in other words, the key structure 1 is in a storage state (as shown in FIG. 13). Wherein, although the horizontal relative position between the first magnetic member 16 and the second magnetic member 20 does not change during this process, in practice, the protrusion 186 is pushed against the force of the first bracket 142 (for example, by The user can still overcome the magnetic attraction force F by pulling or pushing the movable plate 18 ). Therefore, the first bracket 142 can still be rotated by the protrusion 186 logically.

此外，於本實施例中，按鍵結構3亦包含滑槽146及與之互動之滑勾182，於活動板18自該第一位置水平滑動至該第二位置的過程中，滑槽146與滑勾182間產生結構干涉，亦有助於使按鍵結構1處於收納狀態；其作動細節及其結構其他說明，如前文按鍵結構1中相關說明所述，故不另贅述。於實作上，按鍵結構3亦可不透過滑槽146撘配滑勾182，而由凸起部186推抵第一支架142以使按鍵結構1處於收納狀態，不另贅述。In addition, in this embodiment, the button structure 3 also includes a sliding groove 146 and a sliding hook 182 that interacts with it. During the horizontal sliding of the movable plate 18 from the first position to the second position, the sliding groove 146 and the sliding hook 182 The structural interference between the hooks 182 is also helpful to keep the key structure 1 in the storage state; the operation details and other descriptions of the structure are as described in the previous key structure 1 and will not be repeated. In practice, the key structure 3 can also be fitted with the sliding hook 182 without passing through the sliding groove 146, and the protrusion 186 is pushed against the first bracket 142 so that the key structure 1 is in the stored state, which will not be repeated.

於前述按鍵結構1、2、3中，鍵帽12即使未受到按壓外力，仍能下沉以便於收納。又，鍵帽12回復力(即該磁吸力)非由彈性結構產生，可避免先前技術中實體彈性構件可能永久便形而影響彈性的問題。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 aforementioned key structures 1, 2, and 3, even if the key cap 12 is not subjected to external pressing force, it can still sink to facilitate storage. In addition, the restoring force of the keycap 12 (that is, the magnetic attraction force) is not generated by the elastic structure, which can avoid the problem that the solid elastic member may be permanently deformed and affect the elasticity in the prior art. The foregoing descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made in accordance with the scope of the patent application of the present invention should fall within the scope of the present invention.
