本發明提供一種按鍵結構，其可應用於任何按壓式輸入裝置，例如鍵盤，但不以此為限。本發明之按鍵結構藉由升降單元之支架設計，以達到增加結構強度、提升按壓穩定性及流暢度、提高組裝便利性、增加按壓手感源的設計彈性，以滿足使用者需求。於後參考圖式，詳細說明本發明實施例之按鍵結構各元件之結構及操作。 The present invention provides a button structure that can be applied to any push-type input device, such as a keyboard, but is not limited thereto. The button structure of the present invention is designed by the bracket of the lifting unit to increase the structural strength, improve the pressing stability and smoothness, improve the assembly convenience, and increase the design flexibility of the pressing hand source to meet the user's needs. The structure and operation of the components of the key structure of the embodiment of the present invention will be described in detail below with reference to the drawings.

如圖1所示，本發明之按鍵結構10包含底板100、鍵帽200及升降單元300。鍵帽200係設置於底板100上方，而升降單元300連接於鍵帽200及底板100之間，以支撐鍵帽200相對於底板100進行升降運動。具體而言，按鍵結構10係底板100、升降單元300及鍵帽200由下而上依序疊置，且底板100及鍵帽200分別具有連結機構以連接升降單元300(如後詳述)。按鍵結構10還包含開關層400，且開關層400可依據實際設計需求選擇性地置於底板100的上方或下方。舉例而言，當開關層400設置於底板100上方時，開關層400可具有通孔410，使得底板100之連結機構(例如耦接件110、120)可穿過通孔410與升降單元300連接(如圖1所示)。於其他實施例，當開關層400設置於底板100下方時，底板100可具有相應的變化設計(例如孔洞)，以容許鍵帽200向下移動時能觸發開關層400。此外，按鍵結構10可包含回復單元500，其中回復單元500提供鍵帽200曾被按壓但使用者手指已經釋放後上升的回復力。於此實施例，回復單元500係實施為提供彈性回復力之彈性體，但不以此為限。於其他實施例，回復單元500可實施為提供磁力作用的磁性元件。在此需注意，於實施例中雖僅以單一按鍵結構10進行說明，但當複數個按鍵結構10組合成鍵盤時，各按鍵結構10之部分元件(例如底板100、開關層400)可整合成單一部件，以達到降低製造成本與組裝成本之效益。 As shown in FIG. 1, the key structure 10 of the present invention includes a bottom plate 100, a keycap 200, and a lifting unit 300. The keycap 200 is disposed above the bottom plate 100, and the lifting unit 300 is coupled between the keycap 200 and the bottom plate 100 to support the lifting and lowering movement of the keycap 200 relative to the bottom plate 100. Specifically, the button structure 10 is the bottom plate 100, the lifting unit 300, and the keycap 200 are sequentially stacked from bottom to top, and the bottom plate 100 and the keycap 200 respectively have a coupling mechanism to connect the lifting unit 300 (as will be described in detail later). The button structure 10 also includes a switch layer 400, and the switch layer 400 can be selectively placed above or below the backplane 100 depending on actual design requirements. For example, when the switch layer 400 is disposed above the bottom plate 100, the switch layer 400 may have a through hole 410, so that the connection mechanism of the bottom plate 100 (for example, the coupling members 110, 120) can be connected to the lift unit 300 through the through hole 410. (As shown in Figure 1). In other embodiments, when the switch layer 400 is disposed under the bottom plate 100, the bottom plate 100 may have a corresponding change design (eg, a hole) to allow the switch layer 400 to be triggered when the key cap 200 is moved downward. In addition, the button structure 10 can include a reply unit 500, wherein the reply unit 500 provides a restoring force that the keycap 200 has been pressed but has risen after the user's finger has been released. In this embodiment, the recovery unit 500 is implemented as an elastic body that provides an elastic restoring force, but is not limited thereto. In other embodiments, the reply unit 500 can be implemented as a magnetic element that provides a magnetic force. It should be noted that in the embodiment, although only a single button structure 10 is used for description, when a plurality of button structures 10 are combined into a keyboard, some components of each button structure 10 (for example, the bottom plate 100 and the switch layer 400) can be integrated into A single component to achieve the benefits of reduced manufacturing and assembly costs.

如圖1所示，升降單元300包含第一支架320及第二支架310，其中第一支架320及第二支架310係可轉動地樞接，以構成側面具有類似X狀外型的剪刀式升降結構。具體而言，第二支架310較佳係由塑膠材料製成的內塑膠支架(例如封閉式的塑膠框架)，使得第二支架310可利用射出成形技術製造出具有較精細之連結機構，並同時可藉由塑膠材料之彈性特性，提 供組裝第一支架320及第二支架310時所需要的變形量。相對於塑膠材料製成的第二支架310，第一支架320較佳係由剛性相對較強之金屬材料製成的外金屬支架(例如封閉式的金屬框架)，以增加第一支架320及第二支架310組合成升降單元300之整體剛性，進而使按鍵結構整體的作動帶動性提升。第一支架320可利用金屬片(例如鐵片、鋼片等)進行衝壓加工製造，達到高製造性的精準度。再者，第一支架320具有底板端320a及鍵帽端320b，其中底板端320a係靠近底板100，而鍵帽端320b係靠近鍵帽200。於此實施例，底板端320a及鍵帽端320b之連線方向係定義為X軸方向，且底板端320a長軸之延伸方向或鍵帽端320b長軸之延伸方向係定義為Y軸方向，而第一支架320支撐鍵帽200進行升降的方向係定義為Z軸方向。亦即，X軸、Y軸及Z軸方向較佳係以第一支架320平行疊置於底板100的狀態進行定義。在此需注意，於此實施例中第二支架310及第一支架320雖例示為封閉式的框架，但不以此為限。於其他實施例，第二支架310及第一支架320可依據實際需求設計為開放式框架。 As shown in FIG. 1 , the lifting unit 300 includes a first bracket 320 and a second bracket 310 , wherein the first bracket 320 and the second bracket 310 are rotatably pivoted to form a scissor lift having an X-like shape on the side. structure. Specifically, the second bracket 310 is preferably an inner plastic bracket made of a plastic material (for example, a closed plastic frame), so that the second bracket 310 can be manufactured by using injection molding technology to have a finer connecting mechanism, and at the same time Can be improved by the elastic properties of plastic materials The amount of deformation required to assemble the first bracket 320 and the second bracket 310. The first bracket 320 is preferably an outer metal bracket (for example, a closed metal frame) made of a relatively rigid metal material to increase the first bracket 320 and the second bracket 310. The two brackets 310 are combined to form the overall rigidity of the lifting unit 300, thereby improving the overall driving force of the button structure. The first bracket 320 can be stamped and manufactured by using a metal piece (for example, an iron piece, a steel sheet, or the like) to achieve high manufacturability precision. Moreover, the first bracket 320 has a bottom end 320a and a key end 320b, wherein the bottom end 320a is adjacent to the bottom plate 100, and the key end 320b is adjacent to the keycap 200. In this embodiment, the connection direction of the bottom end 320a and the key end 320b is defined as the X-axis direction, and the extending direction of the long axis of the bottom end 320a or the extending direction of the long axis of the key end 320b is defined as the Y-axis direction. The direction in which the first bracket 320 supports the keycap 200 for lifting and lowering is defined as the Z-axis direction. That is, the X-axis, the Y-axis, and the Z-axis direction are preferably defined in a state in which the first holders 320 are stacked in parallel on the bottom plate 100. It should be noted that, in this embodiment, the second bracket 310 and the first bracket 320 are illustrated as a closed frame, but are not limited thereto. In other embodiments, the second bracket 310 and the first bracket 320 can be designed as an open frame according to actual needs.

如圖2A及2B所示，第一支架320的尺寸大於第二支架310，使得第二支架310可樞接於第一支架320之內側。具體而言，作為外金屬支架的第一支架320之尺寸係大於作為內塑膠支架的第二支架310，以使得第一支架320於底板100所在平面之投影範圍實質涵蓋第二支架310於底板所在平面之投影範圍。換言之，當鍵帽200相對於底板100移動到最低位置時(即鍵帽200被按壓到底時)，第一支架320實質上環繞第二支架310。於此實施例，第一支架320較佳具有軸孔322，且第二支架310對應地具有樞軸312，其中軸孔322係為形成於第一支架320兩側向下彎折垂直延伸之側壁上的穿 孔。亦即，軸孔322係為形成於第一支架320沿X軸-Z軸平面延伸之側壁上的穿孔，且軸孔322之中心軸係平行於Y軸方向。樞軸312係為形成於第二支架310架體兩側朝外突出的凸柱。亦即，樞軸312係自第二支架310架體兩側沿Y軸方向相背延伸的凸柱。藉由將樞軸312***軸孔322，以使第一支架320及第二支架310達到可轉動地樞接。在此需注意，於此實施例，樞軸312及軸孔322係大約形成於第一支架320及第二支架310於X軸方向長度的中間，使得升降單元300具有側面類似於X形的剪刀式支撐結構，但不以此為限。於其他實施例，第一支架320及第二支架310之樞接處可設計為接近底板端320a處，而構成側面具有V形的升降結構(如圖12所示)。 As shown in FIGS. 2A and 2B , the first bracket 320 is larger than the second bracket 310 such that the second bracket 310 is pivotally connected to the inner side of the first bracket 320 . Specifically, the size of the first bracket 320 as the outer metal bracket is larger than the second bracket 310 as the inner plastic bracket, so that the projection range of the first bracket 320 on the plane of the bottom plate 100 substantially covers the second bracket 310 at the bottom plate. The projection range of the plane. In other words, when the keycap 200 is moved to the lowest position relative to the bottom plate 100 (ie, when the keycap 200 is pressed to the bottom), the first bracket 320 substantially surrounds the second bracket 310. In this embodiment, the first bracket 320 preferably has a shaft hole 322, and the second bracket 310 correspondingly has a pivot 312. The shaft hole 322 is formed on the side of the first bracket 320 and is bent downward and vertically extending. Wear on hole. That is, the shaft hole 322 is a perforation formed on the side wall of the first bracket 320 extending along the X-axis plane of the X-axis, and the central axis of the shaft hole 322 is parallel to the Y-axis direction. The pivot 312 is a protrusion formed to protrude outward on both sides of the frame of the second bracket 310. That is, the pivot 312 is a post extending from the two sides of the frame of the second bracket 310 in the Y-axis direction. The first bracket 320 and the second bracket 310 are rotatably pivoted by inserting the pivot 312 into the shaft hole 322. It should be noted that in this embodiment, the pivot 312 and the shaft hole 322 are formed approximately in the middle of the length of the first bracket 320 and the second bracket 310 in the X-axis direction, so that the lifting unit 300 has a scissors whose side is similar to the X shape. Support structure, but not limited to this. In other embodiments, the pivotal connection of the first bracket 320 and the second bracket 310 can be designed to be close to the bottom end 320a, and the side surface has a V-shaped lifting structure (as shown in FIG. 12).

於一實施例，樞軸312較佳具有實質矩形之截面以增加樞軸312之強度。具體而言，樞軸312於X軸方向長度大於Z軸方向長度，以便在不增加第二支架310整體厚度(即Z軸方向的高度)的情況下，增加樞軸312的強度，進而降低第一支架320與第二支架310組裝或拆卸時樞軸312發生斷裂的可能性。再者，於一實施例，樞軸312較佳具有導引端部314，且導引端部314包含導引斜面314a，以導引樞軸312伸入軸孔322。如圖2A及圖2C所示，樞軸312之端部係設計為具有弧狀外形的導引端部314，以利於樞軸312於軸孔322中轉動。再者，導引端部314之末端係具有自樞軸外緣朝樞軸軸心傾斜的導引斜面314a。換言之，導引斜面314a使得樞軸312之導引端部314末端沿軸心方向(即Y軸方向)具有漸縮的徑向距離。如圖2A所示，當欲組裝第一支架320與第二支架310時，第二支架310較佳係先設置於第一支架320之下方，然後組裝機台直接施力下壓這個第一支架320和第二支架310所構成的堆疊結構，(1)藉由導引斜面314a的導引並配合第二支架310之塑膠彈性 的特性，使得第二支架310內縮，使樞軸312朝對正軸孔322的位置移動；(2)當樞軸312對正軸孔322時，第二支架310擴張恢復原有外型，使樞軸312***軸孔322中，如此以完成第二支架310與第一支架320的組裝(如圖2B所示)。亦即，升降單元300藉由樞軸312的導引斜面314a的導引，可增進第二支架310及第一支架320組立時的便利性。 In one embodiment, the pivot 312 preferably has a substantially rectangular cross section to increase the strength of the pivot 312. Specifically, the length of the pivot 312 in the X-axis direction is greater than the length in the Z-axis direction so as to increase the strength of the pivot 312 without increasing the overall thickness of the second bracket 310 (ie, the height in the Z-axis direction), thereby reducing the The possibility that the pivot 312 breaks when the bracket 320 is assembled or disassembled with the second bracket 310. Moreover, in an embodiment, the pivot 312 preferably has a guiding end 314, and the guiding end 314 includes a guiding bevel 314a for guiding the pivot 312 into the shaft hole 322. As shown in FIGS. 2A and 2C, the end of the pivot 312 is designed to have an arcuately shaped leading end 314 to facilitate pivoting of the pivot 312 in the shaft bore 322. Furthermore, the end of the guiding end 314 has a guiding bevel 314a that is inclined from the outer edge of the pivot toward the pivot axis. In other words, the guiding ramp 314a causes the end of the leading end 314 of the pivot 312 to have a tapered radial distance in the axial direction (ie, the Y-axis direction). As shown in FIG. 2A, when the first bracket 320 and the second bracket 310 are to be assembled, the second bracket 310 is preferably disposed below the first bracket 320, and then the assembly machine directly applies a force to press the first bracket. The stacking structure formed by the 320 and the second bracket 310 is (1) guided by the guiding slope 314a and matched with the plastic elasticity of the second bracket 310 The second bracket 310 is retracted to move the pivot 312 toward the position of the positive shaft hole 322; (2) when the pivot 312 is aligned with the positive shaft hole 322, the second bracket 310 is expanded to restore the original shape. The pivot 312 is inserted into the shaft hole 322 such that assembly of the second bracket 310 with the first bracket 320 is completed (as shown in FIG. 2B). That is, the lifting unit 300 can improve the convenience of assembling the second bracket 310 and the first bracket 320 by the guiding of the guiding slope 314a of the pivot 312.

再者，於一實施例，如圖1所示，底板100具有耦接件110、120，耦接件110係用於耦接第二支架310，而耦接件120係用於耦接第一支架320。耦接件110、120係突出於底板100上表面並具有彎折的卡勾形式，於此實施例，底板100可由金屬板件藉由衝壓加工製成，使得耦接件110、120可為自底板100表面向上彎折的部件，而使得設置耦接件110、120之底板部分形成開口102a、102b。相應於此，第二支架310係具有卡槽316與耦接件110可轉動地卡合，且第二支架310並具有轉軸部318設置於卡槽316在X軸方向之相對端以連接鍵帽200，使得第二支架310的兩端分別連接於底板100及鍵帽200。再者，於此實施例，底板100具有底板邊緣120a鄰近耦接件120。具體而言，底板邊緣120a係底板100沿Y軸方向延伸以連接耦接件120的邊緣，且底板邊緣120a係界定開口102b的部分邊緣。 Furthermore, in an embodiment, as shown in FIG. 1 , the bottom plate 100 has coupling members 110 and 120 , and the coupling member 110 is coupled to the second bracket 310 , and the coupling member 120 is coupled to the first bracket. Bracket 320. The coupling members 110 and 120 protrude from the upper surface of the bottom plate 100 and have a bent hook form. In this embodiment, the bottom plate 100 can be formed by stamping processing of the metal plate member, so that the coupling members 110 and 120 can be self-contained. The surface of the bottom plate 100 is bent upwardly, so that the bottom plate portions of the coupling members 110, 120 are formed to form openings 102a, 102b. Correspondingly, the second bracket 310 has a card slot 316 and is rotatably engaged with the coupling member 110, and the second bracket 310 has a rotating shaft portion 318 disposed at an opposite end of the slot 316 in the X-axis direction to connect the keycap. 200, the two ends of the second bracket 310 are respectively connected to the bottom plate 100 and the keycap 200. Moreover, in this embodiment, the bottom plate 100 has a bottom edge 120a adjacent to the coupling member 120. Specifically, the bottom plate edge 120a extends in the Y-axis direction to connect the edge of the coupling member 120, and the bottom plate edge 120a defines a portion of the edge of the opening 102b.

第一支架320係具有側翼片324，用於可轉動地卡合底板100之耦接件120。具體而言，側翼片324係自第一支架320之底板端320a之側緣向外延伸的片體。如上所述，第一支架320較佳係由金屬片經衝壓加工彎折成形，因此側翼片324係自第一支架320開設有軸孔322之直立側壁彎折約90度後朝外側實質水平延伸。亦即，側翼片324具有側翼片平面係實質平行於第一支架320的長軸方向(即X軸方向)，或者可視為側翼片平面之法線方向係 實質平行於第一支架320的厚度方向(即Z軸方向)。側翼片324係設置接近於底板端320a，以卡合底板100之耦接件120。此外，側翼片324形成有開口324a，供容置底板100之耦接件120。開口324a較佳為矩形。於此實施例，開口324a係為開放式開口，且其開放端係朝向側翼片324之側緣。具體而言，開口324a自側翼片324由外朝內凹入而形成容置空間。亦即，開口324a係自側翼片324沿X軸方向的部分外緣向內凹入，使得包圍開口324a之部分側翼片324在Y軸方向的延伸長度減小。從另一觀點而言，如圖2A所示，側翼片324係包含第一翼片部323a、第二翼片部323b及第三翼片部323c，其中第二翼片部323b連接於第一翼片部323a及第三翼片部323c之內側(即Y軸方向上靠近軸孔322側)，且第二翼片部323b於Y軸方向之長度小於第一翼片部323a及第三翼片部323c於Y軸方向之長度，使得第一翼片部323a、第二翼片部323b及第三翼片部323c連接圍成開放式開口324a。 The first bracket 320 has side flaps 324 for rotatably engaging the coupling member 120 of the bottom plate 100. Specifically, the side panels 324 are sheets that extend outwardly from the side edges of the bottom end 320a of the first bracket 320. As described above, the first bracket 320 is preferably formed by bending a metal sheet by press working. Therefore, the side flap 324 is bent from the upright side wall of the first bracket 320 and the shaft hole 322 is bent by about 90 degrees, and then extends horizontally to the outside. . That is, the side panel 324 has a side panel plane that is substantially parallel to the long axis direction of the first bracket 320 (ie, the X-axis direction), or can be regarded as the normal direction of the side panel plane. It is substantially parallel to the thickness direction of the first bracket 320 (ie, the Z-axis direction). The side panels 324 are disposed proximate to the bottom end 320a to engage the coupling 120 of the backplane 100. In addition, the side panels 324 are formed with openings 324a for receiving the coupling members 120 of the bottom plate 100. The opening 324a is preferably rectangular. In this embodiment, the opening 324a is an open opening and its open end faces the side edge of the side flap 324. Specifically, the opening 324a is recessed from the side flap 324 from the outside to the inside to form an accommodation space. That is, the opening 324a is recessed inward from a portion of the outer edge of the side flap 324 in the X-axis direction such that the extension length of the portion of the side flap 324 surrounding the opening 324a in the Y-axis direction is reduced. From another point of view, as shown in FIG. 2A, the side panel 324 includes a first flap portion 323a, a second flap portion 323b, and a third flap portion 323c, wherein the second flap portion 323b is coupled to the first flap portion 323b. The inside of the flap portion 323a and the third flap portion 323c (that is, on the side closer to the shaft hole 322 in the Y-axis direction), and the length of the second flap portion 323b in the Y-axis direction is smaller than the first flap portion 323a and the third flap The length of the sheet portion 323c in the Y-axis direction is such that the first flap portion 323a, the second flap portion 323b, and the third flap portion 323c are connected to form an open opening 324a.

圖3A係第一支架320連接於底板100之示意圖，且圖3B及圖3C分別為側翼片324與底板100之耦接件120局部放大之側視及底視示意圖。如圖3A-3C所示，當第一支架320連接於底板100時，第一支架320係置於底板100之上表面，且耦接件120係容置於側翼片324之開口324a並自開口324a向上伸出，使得側翼片324之下表面324b與耦接件120附近之底板邊緣120a呈線性接觸(兩者互相接觸處均位於一條線上)，如此以形成支撐鍵帽200相對於底板100進行升降運動時第一支架320之轉軸支點，使得第一支架320可相對於底板邊緣120a轉動。具體而言，(1)底板100接觸區域為底板邊緣120a：係為界定開口102b的部分底板邊緣，亦即係底板100於開口102b中沿Y軸方向延伸連接耦接件120的底板邊緣；(2)側翼片324接觸區域係接觸線 L：大約是沿著開口324a之側緣324a1於側翼片324之下表面在Y軸方向的延伸線(即大約為第一翼片部323a及第二翼片部323b的連接處)，且隨著鍵帽200相對於底板100升降時，該接觸線L在側翼片下表面324b上可能會有些許移動，例如：接觸線L’。換言之，第一翼片部323a下表面及第二翼片部323b下表面係連接形成平坦下表面，以作為側翼片324與底板邊緣102a之接觸區域。 FIG. 3A is a schematic view showing the first bracket 320 connected to the bottom plate 100, and FIG. 3B and FIG. 3C are respectively a partially enlarged side view and a bottom view of the coupling member 120 of the side panel 324 and the bottom plate 100. As shown in FIGS. 3A-3C, when the first bracket 320 is coupled to the bottom plate 100, the first bracket 320 is disposed on the upper surface of the bottom plate 100, and the coupling member 120 is received in the opening 324a of the side panel 324 and is open from the opening. The 324a extends upwardly such that the lower surface 324b of the side panel 324 is in linear contact with the bottom edge 120a of the vicinity of the coupling member 120 (the two are in contact with each other on a line), so that the support keycap 200 is formed relative to the bottom plate 100. The pivot point of the first bracket 320 during the lifting movement causes the first bracket 320 to rotate relative to the bottom edge 120a. Specifically, (1) the contact area of the bottom plate 100 is the bottom plate edge 120a: a part of the bottom plate edge defining the opening 102b, that is, the bottom plate 100 extends in the Y-axis direction in the opening 102b to connect the bottom edge of the coupling member 120; 2) Side flap 324 contact area contact line L: approximately along the side edge 324a1 of the opening 324a in the Y-axis direction of the lower surface of the side flap 324 (ie, approximately the junction of the first flap portion 323a and the second flap portion 323b), and When the keycap 200 is raised and lowered with respect to the bottom plate 100, the contact line L may slightly move on the side flap lower surface 324b, for example, the contact line L'. In other words, the lower surface of the first fin portion 323a and the lower surface of the second fin portion 323b are joined to form a flat lower surface as a contact area between the side flap 324 and the bottom edge 102a.

再者，耦接件120具有卡勾頂部122與卡勾直立部123，其中卡勾直立部123係鄰接底板邊緣120a並實質延伸於底板100之上表面的法線方向(即Z軸方向)，且卡勾頂部122係自卡勾直立部123朝X軸方向延伸。當第一支架320與底板100連接時，卡勾直立部123係位於側翼片324之開口324a中，使得第一翼片部323a及第二翼片部323b分別鄰近卡勾直立部123的兩相鄰側(即Y軸與X軸兩側)，第一翼片部323a及第三翼片部323c分別鄰近卡勾直立部123的兩相對側(即X軸相對側)。再者，於此實施例，卡勾頂部122係具有弧形下表面122a以作為與側翼片324之上表面324c(即第一翼片部323a之上表面)接觸的弧形接觸面，該弧形下表面122a末端鄰接卡勾直立部123處較佳形成收納凹槽123a。亦即，卡勾頂部122之下表面係相對於X軸方向形成弧形下表面122a。當升降單元300因應鍵帽200相對於底板100升降時，第一支架320係藉由側翼片324之下表面324b與底板邊緣120a的線性接觸進行轉動；此時卡勾頂部122之弧形下表面122a係接觸側翼片324的上表面324c(即第一翼片部323a之上表面)，使得側翼片324藉由弧形下表面122a的導引沿著弧形下表面122a轉動，且收納凹槽123a可容置側翼片上表面324c右上角324d，增加升降運動的穩定度及流暢度。再者，於此實施例雖例示 卡勾頂部122與卡勾直立部123鄰接處係形成收納凹槽123a，但不以此為限。於其他實施例，如圖3D所示，卡勾頂部122之下表面122b與卡勾直立部123鄰接處可以是水平直線，而製作側翼片右上角324d時會自然形成圓弧角，如此兩者之間只有很小的干涉，亦足以順利轉動。 Furthermore, the coupling member 120 has a hook top portion 122 and a hook upright portion 123, wherein the hook upright portion 123 abuts the bottom plate edge 120a and substantially extends in a normal direction (ie, a Z-axis direction) of the upper surface of the bottom plate 100, The hook top portion 122 extends from the hook upright portion 123 in the X-axis direction. When the first bracket 320 is coupled to the bottom plate 100, the hook upright portion 123 is located in the opening 324a of the side panel 324 such that the first flap portion 323a and the second flap portion 323b are adjacent to the two phases of the hook upright portion 123, respectively. Adjacent sides (i.e., both sides of the Y-axis and the X-axis), the first fin portion 323a and the third fin portion 323c are respectively adjacent to opposite sides of the hook upright portion 123 (i.e., opposite sides of the X-axis). Moreover, in this embodiment, the hook top 122 has a curved lower surface 122a as an arcuate contact surface that contacts the upper surface 324c of the side panel 324 (ie, the upper surface of the first flap portion 323a). Preferably, the end of the lower surface 122a adjacent to the hook upright portion 123 forms a receiving recess 123a. That is, the lower surface of the hook top 122 forms an arcuate lower surface 122a with respect to the X-axis direction. When the lifting unit 300 moves up and down with respect to the bottom plate 100 in response to the keycap 200, the first bracket 320 is rotated by the linear contact of the lower surface 324b of the side flap 324 with the bottom edge 120a; at this time, the curved lower surface of the top portion 122 of the hook 122a is in contact with the upper surface 324c of the side flap 324 (i.e., the upper surface of the first flap portion 323a) such that the side flap 324 is rotated along the curved lower surface 122a by the guiding of the curved lower surface 122a, and the recess is received. 123a can accommodate the upper right corner 324d of the upper surface 324c of the side flap to increase the stability and smoothness of the lifting movement. Furthermore, this embodiment is illustrated The storage hook groove 123a is formed adjacent to the hook top portion 122 and the hook upright portion 123, but is not limited thereto. In other embodiments, as shown in FIG. 3D, the lower surface 122b of the hook top 122 may be a horizontal straight line adjacent to the hook upright portion 123, and the arc angle may be naturally formed when the right side corner 324d of the side flap is formed. There is only a small amount of interference between them, which is enough to rotate smoothly.

換言之，本發明之按鍵結構10藉由底板100開設耦接件120界定出開口102b的底板邊緣120a係具有較高的製造精準度，而可達到藉由側翼片324與耦接件120附近之底板邊緣120a的線性接觸作為轉動支點，進而提升按鍵結構10之按壓穩定性。再者，耦接件120相對於底板100之上表面係實質彎折90度，因此彎折角度容易控制。在此需注意，於此實施例，雖以界定開口102b之部分邊緣作為底板邊緣120a，但於其他實施例，底板邊緣120a可為底板其他部份的邊緣。舉例而言，於其他實施例，可相對於底板之上表面在鄰近耦接件120之處形成具有段差的凹陷部，使得底板鄰接凹陷部的段差邊緣作為上述的底板邊緣120a。亦即，底板邊緣120a較佳係底板於鄰近耦接件120處在X軸方向中止或彎折所形成的邊緣。 In other words, the key structure 10 of the present invention defines the bottom edge 120a of the opening 102b by the opening of the bottom plate 100 to have a high manufacturing precision, and can be achieved by the side panel 324 and the bottom plate near the coupling 120. The linear contact of the edge 120a acts as a pivot point, thereby enhancing the press stability of the button structure 10. Moreover, the coupling member 120 is substantially bent by 90 degrees with respect to the upper surface of the bottom plate 100, so that the bending angle is easily controlled. It should be noted here that in this embodiment, although a part of the edge defining the opening 102b is used as the bottom edge 120a, in other embodiments, the bottom edge 120a may be the edge of other portions of the bottom plate. For example, in other embodiments, a recess having a step can be formed adjacent the coupling 120 with respect to the upper surface of the bottom plate such that the bottom edge abuts the step edge of the recess as the bottom edge 120a described above. That is, the bottom edge 120a is preferably a bottom plate formed at an edge formed by the end of the coupling member 120 in the X-axis direction.

再者，鍵帽200具有連結機構供連接升降單元之第一支架320及第二支架310。於一實施例，如圖4A-4D所示，鍵帽200之下表面設有轉軸道210，且轉軸道210係與第二支架310之轉軸部318可轉動地卡合。此外，鍵帽200還具有滑槽220形成於鍵帽200之下表面。滑槽220係與第一支架320可滑動地耦接，且滑槽220具有上滑動面222與下滑動面224。具體而言，鍵帽200具有一對連結機構221係自鍵帽200之下表面向下突出並具有相對的L形截面以界定出滑槽220，使得兩個L形截面的水平部係作為滑槽220的下滑動面224，而對應的鍵帽200下表面係作為滑槽220的上滑動面222。 Furthermore, the keycap 200 has a coupling mechanism for connecting the first bracket 320 and the second bracket 310 of the lifting unit. In one embodiment, as shown in FIGS. 4A-4D, the lower surface of the keycap 200 is provided with a rotating shaft 210, and the rotating shaft 210 is rotatably engaged with the rotating shaft portion 318 of the second bracket 310. Further, the keycap 200 further has a chute 220 formed on a lower surface of the keycap 200. The chute 220 is slidably coupled to the first bracket 320, and the chute 220 has an upper sliding surface 222 and a lower sliding surface 224. Specifically, the keycap 200 has a pair of coupling mechanisms 221 protruding downward from the lower surface of the keycap 200 and having opposite L-shaped cross sections to define the chute 220 such that the horizontal portions of the two L-shaped sections are used as slip The lower sliding surface 224 of the groove 220 and the lower surface of the corresponding key cap 200 serve as the upper sliding surface 222 of the chute 220.

相應於此，第一支架320具有S形延伸部326，用於和鍵帽200之滑槽220耦接。具體而言，S形延伸部326係自鍵帽端320b之端緣向外彎折延伸。亦即，S形延伸部326係自第一支架320之鍵帽端320b的端緣沿X軸方向朝外彎折延伸，使得S形延伸部326於X軸方向上具有S形截面。S形延伸部326具有上彎折面326a與下彎折面326b，且上彎折面326a與下彎折面326b的曲率中心係沿滑槽220之延伸方向(即X軸方向或第一支架320之滑動方向)設置。亦即，藉由第一支架320係由金屬片衝壓彎折所形成，使得S形延伸部326因為金屬彎折的延展特性而於S形延伸部326的兩個彎折部分形成圓弧面，以分別作為上彎折面326a與下彎折面326b，使得上彎折面326a與下彎折面326b之曲率中心係沿X軸方向設置，如此以減小S形延伸部326在Z軸方向上的厚度，以利於按鍵結構的微型化。如圖4C及圖4D所示，升降單元300係藉由上彎折面326a與下彎折面326b分別與上滑動面222及下滑動面224接觸以作為滑動的導引面。亦即，當鍵帽200相對底板100進行升降運動時，第一支架320係藉由上彎折面326a及下彎折面326b分別與上滑動面222及下滑動面224的接觸產生弧面導引作用而相對於鍵帽200進行滑動，進而使得升降運動更為流暢。 Correspondingly, the first bracket 320 has an S-shaped extension 326 for coupling with the sliding slot 220 of the keycap 200. Specifically, the S-shaped extension 326 extends outwardly from the end edge of the keycap end 320b. That is, the S-shaped extension portion 326 is bent outwardly from the end edge of the key end 320b of the first bracket 320 in the X-axis direction such that the S-shaped extension portion 326 has an S-shaped cross section in the X-axis direction. The S-shaped extension 326 has an upper bending surface 326a and a lower bending surface 326b, and the center of curvature of the upper bending surface 326a and the lower bending surface 326b is along the extending direction of the sliding slot 220 (ie, the X-axis direction or the first bracket) 320 sliding direction) setting. That is, the first bracket 320 is formed by stamping and bending a metal sheet, so that the S-shaped extending portion 326 forms a circular arc surface at the two bent portions of the S-shaped extending portion 326 due to the ducting property of the metal bending. The upper curved surface 326a and the lower curved surface 326b are respectively disposed such that the center of curvature of the upper curved surface 326a and the lower curved surface 326b are disposed along the X-axis direction, so as to reduce the S-shaped extending portion 326 in the Z-axis direction. The thickness on the top to facilitate miniaturization of the button structure. As shown in FIG. 4C and FIG. 4D, the lifting unit 300 is in contact with the upper sliding surface 222 and the lower sliding surface 224 by the upper bending surface 326a and the lower bending surface 326b as a sliding guiding surface. That is, when the keycap 200 is moved up and down with respect to the bottom plate 100, the first bracket 320 generates an arc guide by the contact of the upper curved surface 326a and the lower curved surface 326b with the upper sliding surface 222 and the lower sliding surface 224, respectively. The sliding is performed relative to the keycap 200, thereby making the lifting movement smoother.

再者，第一支架320可具有導引面321，以作為升降單元300與鍵帽200組裝時的定位導引面。於一實施例，參考圖2A及圖4A，第一支架320之導引面321係設置於鄰近S形延伸部326之側邊。具體而言，第一支架320係自鍵帽端320b之側緣向下彎折形成導引面321。於一實施例，導引面321係為第一支架320沿X軸方向向下彎折的側壁外表面。類似地，藉由第一支架320係由金屬片衝壓彎折所形成，使得向下彎折的側壁因為金屬彎折 的延展特性而於彎折部分形成具有圓弧角的導引面321。當鍵帽200與第一支架320組裝時，鍵帽200可藉由導引面321的圓弧角定位導引，使得連結機構221沿導引面321向下移動而與第一支架320耦接，藉此提升組裝的便利性。 Furthermore, the first bracket 320 may have a guiding surface 321 as a positioning guide surface when the lifting unit 300 is assembled with the keycap 200. In one embodiment, referring to FIG. 2A and FIG. 4A , the guiding surface 321 of the first bracket 320 is disposed adjacent to the side of the S-shaped extending portion 326 . Specifically, the first bracket 320 is bent downward from the side edge of the keycap end 320b to form a guiding surface 321 . In one embodiment, the guiding surface 321 is a side wall outer surface of the first bracket 320 that is bent downward in the X-axis direction. Similarly, the first bracket 320 is formed by stamping and bending a metal sheet, so that the downwardly bent side wall is bent due to the metal. The ducting characteristic forms a guiding surface 321 having a circular arc angle in the bent portion. When the keycap 200 is assembled with the first bracket 320, the keycap 200 can be guided by the arcuate angle of the guiding surface 321, so that the connecting mechanism 221 is moved downward along the guiding surface 321 to be coupled with the first bracket 320. , thereby improving the convenience of assembly.

The components 318 and the like are rotatably coupled to the shaft hole 322 of the first bracket 320', the coupling member 110 of the bottom plate 100, and the rotating shaft 210 of the keycap 200, respectively. For details on the construction of the second bracket 310, reference may also be made to the related description of FIG. Similarly, the first bracket 320' of the present embodiment is preferably an outer metal frame manufactured by press working from a relatively rigid metal sheet to increase the combination of the first bracket 320' and the second bracket 310 into a lifting unit. The overall rigidity of the 300' further enhances the overall actuation of the button structure. In this embodiment, as shown in FIGS. 6A-6B, the first bracket 320' has a shaft hole 322 to rotatably engage with the pivot 312 of the second bracket 310 to form a lifting unit 300', and the first bracket For details of the pivoting of the second bracket 310 to the second bracket 310 by the shaft hole 322 and the pivot shaft 312, reference may be made to the related description of FIG.

再者，第一支架320’係具有側翼片324’，用於可轉動地卡合底板100之耦接件120。側翼片324’係自第一支架320’之底板端320a之側緣向外延伸。相對於圖1之第一支架320之側翼片324具有開放式開口324a的設計，本實施例的側翼片324’係具有封閉式開口324a’，以供容置底板100之耦接件120。具體而言，側翼片324’係自第一支架320’之底板端320a之側緣沿Y軸方向朝外水平延伸的片體，而開口324a’係開設於鄰近第二支架側緣之側翼片324’上的通孔，且開口324a’較佳為矩形。具體而言，側翼片324’係包含第一翼片部323a’、第二翼片部323b’及第三翼片部323c’，其中第二翼片部323b’連接於第一翼片部323a’及第三翼片部323c’之外側(即Y軸方向上遠離軸孔322側)，且第二翼片部323b’於Y軸方向之長度小於第一翼片部323a’及第三翼片部323c’於Y軸向之長度，使得第一翼片部323a’、第二翼片部323b’及第三翼片部323c’連接圍成封閉式開口324a’。 Further, the first bracket 320' has a side flap 324' for rotatably engaging the coupling member 120 of the bottom plate 100. The side panels 324' extend outwardly from the side edges of the bottom end 320a of the first bracket 320'. The side panel 324' of the first bracket 320 of Fig. 1 has a design of an open opening 324a. The side panel 324' of the present embodiment has a closed opening 324a' for receiving the coupling member 120 of the bottom plate 100. Specifically, the side flap 324' is a sheet extending horizontally outward from the side edge of the bottom end 320a of the first bracket 320' in the Y-axis direction, and the opening 324a' is formed on the side flap adjacent to the side edge of the second bracket. The through hole in 324', and the opening 324a' is preferably rectangular. Specifically, the side panel 324' includes a first flap portion 323a', a second flap portion 323b', and a third flap portion 323c', wherein the second flap portion 323b' is coupled to the first flap portion 323a. 'and the outer side of the third fin portion 323c' (ie, away from the shaft hole 322 side in the Y-axis direction), and the length of the second fin portion 323b' in the Y-axis direction is smaller than the first fin portion 323a' and the third wing The length of the piece portion 323c' in the Y-axis direction is such that the first flap portion 323a', the second flap portion 323b', and the third flap portion 323c' are connected to form a closed opening 324a'.

圖7A係第一支架320’連接於底板100之示意圖，且圖7B係為側翼片324’與底板100之耦接件120局部放大之底視示意圖。如圖7A-7B所示，當第一支架320’連接於底板100時，第一支架320’係置於底板100之上表面，且耦接件120穿過側翼片324’之開口324a’伸出，使得側翼片324’之下表面324b’與耦接件120附近之底板邊緣120a呈線性接觸，以形成支撐鍵帽200相對於底板100進行升降運動之轉軸支點。具體而言，底板邊緣120a可視為界定開口102b的部分底板邊緣。亦即，底板邊緣120a係底板100於開口102b中沿Y軸方向延伸連接耦接件120的底板邊緣，使得側翼片324’與耦接件120呈線性接觸的接觸線大約為開口324a’之側緣324a2於側翼片324’之下表面324b’在Y軸方向的延伸線(即大約為第一翼片部323a’及第二翼片部323b’的 連接處)。於此實施例，側翼片324’係藉由包圍於開口324a’之外側部分的下表面與底板邊緣120a進行線接觸，而圖1A之側翼片324係藉由環繞開口324a內側部分的下表面與底板邊緣120a進行線接觸，但不以此為限。於其他實施例，可藉由改變開口324a’的位置，例如開設於側翼片的中間而使得開口324a’於Y軸方向兩側均保留有部分側翼片，以使側翼片可藉由包圍於開口324a’之內側及外側部分的下表面與底板邊緣120a進行線接觸。 7A is a schematic view showing the first bracket 320' attached to the bottom plate 100, and FIG. 7B is a partially enlarged bottom view of the coupling member 120 of the side panel 324' and the bottom plate 100. As shown in FIGS. 7A-7B, when the first bracket 320' is coupled to the bottom plate 100, the first bracket 320' is placed on the upper surface of the bottom plate 100, and the coupling member 120 extends through the opening 324a' of the side flap 324'. The lower surface 324b' of the side panel 324' is brought into linear contact with the bottom edge 120a of the vicinity of the coupling member 120 to form a pivot fulcrum for supporting the lifting and lowering movement of the keycap 200 relative to the bottom plate 100. In particular, the bottom edge 120a can be considered to define a portion of the bottom edge of the opening 102b. That is, the bottom edge 120a of the bottom plate 100 extends in the Y-axis direction in the opening 102b to connect the bottom edge of the coupling member 120 such that the contact line of the side flap 324' in linear contact with the coupling member 120 is approximately the side of the opening 324a'. The edge 324a2 is an extension line of the lower surface 324b' of the side flap 324' in the Y-axis direction (ie, approximately the first flap portion 323a' and the second flap portion 323b' Junction). In this embodiment, the side panels 324' are in line contact with the bottom edge 120a by a lower surface surrounding the outer portion of the opening 324a', and the side flaps 324 of FIG. 1A are surrounded by the lower surface of the inner portion of the opening 324a. The bottom edge 120a is in line contact, but is not limited thereto. In other embodiments, by changing the position of the opening 324a', for example, in the middle of the side panel, the opening 324a' retains a portion of the side flaps on both sides of the Y-axis direction, so that the side panel can be surrounded by the opening. The lower surface of the inner and outer portions of 324a' is in line contact with the bottom edge 120a.

再者，類似於上述，當第一支架320’與底板100連接時，卡勾直立部123係位於側翼片324’之開口324a’中，使得第一翼片部323a’及第二翼片部323b’分別鄰近卡勾直立部123的兩相鄰側(即Y軸與X軸兩側)，第一翼片部323a’及第三翼片部323c’分別鄰近卡勾直立部123的兩相對側(即X軸相對側)，且第一翼片部323a’係位於底板100及卡勾頂部122之間。耦接件120之卡勾頂部122的弧形下表面122a亦可作為與側翼片324’之上表面324c’(即第一翼片部323a’之上表面)接觸的弧形接觸面。當升降單元300’相對於底板100升降時，第一支架320’係藉由側翼片324’之下表面324b’與底板邊緣120a的線性接觸進行轉動運動，且卡勾頂部122之弧形下表面122a係接觸側翼片324’的上表面324c’，使得側翼片324’藉由弧形下表面122a的導引沿著弧形下表面122a運動，增加升降運動的穩定度及流暢度。 Moreover, similarly to the above, when the first bracket 320' is coupled to the bottom plate 100, the hook upright portion 123 is located in the opening 324a' of the side flap 324' such that the first flap portion 323a' and the second flap portion 323b' are adjacent to two adjacent sides of the hook upright portion 123 (ie, both sides of the Y-axis and the X-axis), and the first flap portion 323a' and the third flap portion 323c' are respectively adjacent to the opposite sides of the hook upright portion 123. The side (ie, the opposite side of the X-axis), and the first flap portion 323a' is located between the bottom plate 100 and the top 122 of the hook. The curved lower surface 122a of the hook top 122 of the coupling member 120 can also serve as an arcuate contact surface that contacts the upper surface 324c' of the side panel 324' (i.e., the upper surface of the first flap portion 323a'). When the lifting unit 300' is raised and lowered relative to the bottom plate 100, the first bracket 320' is rotated by the linear contact of the lower surface 324b' of the side flap 324' with the bottom edge 120a, and the curved lower surface of the top 122 of the hook 122a contacts the upper surface 324c' of the side flap 324' such that the side flap 324' moves along the curved lower surface 122a by the guiding of the curved lower surface 122a, increasing the stability and smoothness of the lifting movement.

再者，如圖8A-8D所示，第一支架320’具有彎折面325a，彎折面325a係鍵帽端320b之端緣向下彎折延伸，且彎折面325a係作為滑動的上導引面。具體而言，第一支架320’係自鍵帽端320b之端緣向下彎折形成側壁325，且因為金屬彎折的延展特性而於第一支架320’板面及側壁325連接之彎折部分形成圓弧的彎折面325a。第一支架320’並具有彎折部328，彎折部328 係設置於鍵帽端320b鄰接端緣之側緣。具體而言，第一支架320’係自鍵帽端320a之側緣向下彎折形成彎折部328，且彎折部328的表面係平行於X軸方向。彎折部328具有圓弧端面328a，且圓弧端面328a係作為滑動的下導引面。亦即，彎折部328的下端係形成圓弧狀，使得彎折部328的下端面成為圓弧端面328a。 Furthermore, as shown in FIGS. 8A-8D, the first bracket 320' has a bent surface 325a, and the end surface of the curved surface 325a is bent downwardly, and the curved surface 325a is used as a sliding upper surface. Guide surface. Specifically, the first bracket 320' is bent downward from the end edge of the key end 320b to form the side wall 325, and is bent at the connection between the board surface and the side wall 325 of the first bracket 320' because of the extending property of the metal bending. A portion of the arcuate curved surface 325a is formed. The first bracket 320' has a bent portion 328, and the bent portion 328 It is disposed on the side edge of the key end 320b adjacent to the end edge. Specifically, the first bracket 320' is bent downward from the side edge of the keycap end 320a to form a bent portion 328, and the surface of the bent portion 328 is parallel to the X-axis direction. The bent portion 328 has a circular arc end surface 328a, and the circular arc end surface 328a serves as a sliding lower guide surface. That is, the lower end of the bent portion 328 is formed in an arc shape such that the lower end surface of the bent portion 328 becomes the circular arc end surface 328a.

當第一支架320’與鍵帽200組裝時，鍵帽200可藉由彎折面325a的導引耦接第一支架320’，以提升組裝的便利性。此外，如圖8C及圖8D所示，升降單元300’係藉由彎折面325a與鍵帽200之上滑動面222接觸，且圓弧端面328a係接觸鍵帽200之下滑動面224，使得作為上導引面的彎折面325a於上滑動面222滑動，作為下導引面的圓弧端面328a於下滑動面224滑動。亦即，當鍵帽200相對底板100進行升降運動時，第一支架320’係藉由彎折面325a及圓弧端面328a分別與上滑動面222及下滑動面224的接觸產生弧面導引作用而相對於鍵帽200進行滑動，進而使得升降運動更為流暢。 When the first bracket 320' is assembled with the keycap 200, the keycap 200 can be coupled to the first bracket 320' by the guiding of the bending surface 325a to improve the assembly convenience. In addition, as shown in FIG. 8C and FIG. 8D, the lifting unit 300' is in contact with the sliding surface 222 above the keycap 200 by the bending surface 325a, and the circular arc end surface 328a contacts the sliding surface 224 below the keycap 200, so that The bending surface 325a as the upper guiding surface slides on the upper sliding surface 222, and the circular arc end surface 328a as the lower guiding surface slides on the lower sliding surface 224. That is, when the keycap 200 is moved up and down with respect to the bottom plate 100, the first bracket 320' is curved by the contact of the curved surface 325a and the circular arc end surface 328a with the upper sliding surface 222 and the lower sliding surface 224, respectively. The function is to slide relative to the keycap 200, thereby making the lifting movement smoother.

再者，第一支架320’亦可具有類似的導引面321，以作為升降單元300’與鍵帽200組裝時的定位導引面。於一實施例，參考圖6A，第一支架320’之導引面321係設置於鄰近彎折部328。具體而言，第一支架320’係自鍵帽端320b之側緣向下彎折形成導引面321。換言之，導引面321可為第一支架320’沿X軸方向向下彎折的側壁外表面。類似地，藉由第一支架320’係由金屬片衝壓彎折所形成，使得向下彎折的側壁因為金屬彎折的延展特性而於彎折部分形成具有圓弧角的導引面321。當鍵帽200與第一支架320’組裝時，鍵帽200可藉由導引面321的圓弧角定位導引，沿導引面321向下移動而與第一支架320’耦接，藉此提升組裝的便利性。 Further, the first bracket 320' may have a similar guiding surface 321 as a positioning guide surface when the lifting unit 300' is assembled with the keycap 200. In one embodiment, referring to FIG. 6A, the guiding surface 321 of the first bracket 320' is disposed adjacent to the bent portion 328. Specifically, the first bracket 320' is bent downward from the side edge of the keycap end 320b to form a guiding surface 321 . In other words, the guiding surface 321 may be a side wall outer surface of the first bracket 320' which is bent downward in the X-axis direction. Similarly, the first bracket 320' is formed by stamping and bending a metal sheet such that the downwardly bent side wall forms a guiding surface 321 having a circular arc angle at the bent portion due to the ducting property of the metal bending. When the keycap 200 is assembled with the first bracket 320', the keycap 200 can be guided by the arcuate angle of the guiding surface 321 and moved downward along the guiding surface 321 to be coupled with the first bracket 320'. This improves the convenience of assembly.

參考圖9，於另一實施例，第一支架320更具有觸發部329，觸發部329自第二支架之底板端320a之端緣向下突伸以因應鍵帽200之升降運動觸發開關層400。具體而言，觸發部329係自第一支架320之底板端320a之內緣沿X軸方向向內延伸並向下突出的舌片。當按壓鍵帽200朝底板100向下移動時，升降單元300係下降，使得觸發部329亦向下移動進而觸發開關層400。在此需注意，於此雖以第一支架320說明觸發部329之設置，然而第一支架320’於相應位置亦可設置觸發部329，於此不再贅述。藉由整合觸發部329於第一支架320、320’可使得回復單元500之設計更有彈性，以增進按壓操作。舉例而言，當觸發部329整合於第一支架320、320’時，作為回復單元500的彈性體可以不必於下表面設置觸發開關層的凸柱，使得彈性體的升降行程增加，進而提升使用者的按壓操作的手感。 Referring to FIG. 9 , in another embodiment, the first bracket 320 further has a triggering portion 329 protruding downward from an end edge of the bottom end 320 a of the second bracket to trigger the switch layer 400 in response to the lifting motion of the key cap 200 . . Specifically, the trigger portion 329 is a tongue that extends inward from the inner edge of the bottom plate end 320a of the first bracket 320 in the X-axis direction and protrudes downward. When the keycap 200 is pressed downward toward the bottom plate 100, the lifting unit 300 is lowered, so that the trigger portion 329 also moves downward to trigger the switch layer 400. It should be noted that, although the setting of the triggering portion 329 is described by the first bracket 320, the triggering portion 329 may be disposed at the corresponding position of the first bracket 320', and details are not described herein. The integration of the triggering portion 329 to the first brackets 320, 320' can make the design of the reply unit 500 more flexible to enhance the pressing operation. For example, when the triggering portion 329 is integrated into the first brackets 320, 320', the elastic body as the returning unit 500 may not need to provide the protruding column of the triggering switch layer on the lower surface, so that the lifting stroke of the elastic body is increased, thereby improving the use. The feel of the user's pressing operation.

於上述圖1及圖5之實施例中，第一支架320、320’係作為剪刀式升降單元300、300’中兩個樞接支架中的其中一個支架，然而於其他實施例中，亦可改變第一支架的部分結構而使其作為剪刀式升降單元中兩個樞接支架外的輔助支架，以在既有的剪刀式結構進一步增加升降單元的剛性進而提升按鍵整體的結構強度。如圖10所示，於另一實施例，本發明提供一種按鍵結構30，其包含底板150、鍵帽250及升降單元600，其中鍵帽250係設置於底板150上方，而升降單元600連接於鍵帽250及底板150之間，以支撐鍵帽250相對於底板150進行升降運動。在此需注意，圖10雖未繪示，但是按鍵結構30亦可具有類似上述的開關層及回復單元，於此不再贅述。於此實施例，升降單元600係包含第一支架610、第二支架620及第三支架630，其中第二支架620及第三支架630係可轉動地樞接以構成剪刀式連動結 構，且第一支架610可與第二支架620及第三支架630以無結構連動的方式連接底板150及鍵帽250，以加強升降單元600的剛性。具體而言，第二支架620及第三支架630可為習知利用塑膠材料製成的內/外框架，並於支架中段部分藉由例如樞軸622及軸孔632可轉動地樞接。第二支架620及第三支架630於其兩端各具有連結部，以連接底板150及鍵帽250。舉例而言，第二支架620具有卡槽624與底板150的卡勾152可轉動地卡合，並於卡槽624的相對端具有轉軸部626與鍵帽之卡槽252可轉動地卡合。相應地，第三支架630具有轉軸部634與底板150的卡勾154可轉動地卡合，並於轉軸部634的相對端具有滑軌部636與鍵帽250之滑槽254可滑動地耦接。 In the above embodiments of FIG. 1 and FIG. 5, the first brackets 320, 320' are used as one of the two pivot brackets of the scissor lifting unit 300, 300', but in other embodiments, The partial structure of the first bracket is changed to serve as an auxiliary bracket outside the two pivot brackets of the scissor lifting unit, so as to further increase the rigidity of the lifting unit in the existing scissor structure and thereby improve the structural strength of the entire button. As shown in FIG. 10, in another embodiment, the present invention provides a button structure 30 including a bottom plate 150, a key cap 250, and a lifting unit 600, wherein the key cap 250 is disposed above the bottom plate 150, and the lifting unit 600 is coupled to Between the keycap 250 and the bottom plate 150, the support key cap 250 is moved up and down relative to the bottom plate 150. It should be noted that, although not shown in FIG. 10, the button structure 30 can also have a switch layer and a reply unit similar to those described above, and details are not described herein again.
