請參閱第2圖至第5圖,第5圖為本發明實施例電路板4的***示意圖。如第2圖至第5圖所示,電路板4設置於板體10的頂面101上且包含有一第一層結構40、一第二層結構41以及一第三層結構42,第二層結構41結合於第一層結構40,第三層結構42設置於底板1的板體10的頂面101上且結合於第二層結構41,亦即第一層結構40是設置於第二層結構41上,且第二層結構41位於第一層結構40與第三層結構42之間,也就是說,電路板4由板體10的頂面101開始依序以第三層結構42、第二層結構41及第一層結構40的順序設置。進一步地,第一層結構40對應第二桿部31處形成有套設孔座11的一第一開口401,第一開口401具有一第一側邊402及相對第一側邊402之一第二側邊403。Referring to FIGS. 2 to 5, FIG. 5 is a schematic exploded view of the circuit board 4 according to an embodiment of the present invention. As shown in FIG. 2 to FIG. 5, the circuit board 4 is disposed on the top surface 101 of the board body 10 and includes a first layer structure 40, a second layer structure 41, and a third layer structure 42, the second layer. The structure 41 is coupled to the first layer structure 40. The third layer structure 42 is disposed on the top surface 101 of the board 10 of the bottom plate 1 and coupled to the second layer structure 41, that is, the first layer structure 40 is disposed on the second layer. On the structure 41, and the second layer structure 41 is located between the first layer structure 40 and the third layer structure 42, that is, the circuit board 4 is sequentially formed by the top surface 101 of the board body 10 by the third layer structure 42, The second layer structure 41 and the first layer structure 40 are arranged in sequence. Further, the first layer structure 40 corresponds to a first opening 401 formed with the sleeve hole 11 at the second rod portion 31. The first opening 401 has a first side 402 and a first side 402 Two sides 403.
另外,電路板4另包含有一第一彈抵舌片43及一第二彈抵舌片44,第一彈抵舌片43突出於第一開口401的第一側邊402,第二彈抵舌片44突出於第一開口401的第二側邊403且與第一彈抵舌片43相對。值得一提的是,孔座11的樞接孔110的一延伸方向X1係平行於第一側邊402與第二側邊403,因此當支撐桿3的第二桿部31穿設於孔座11的樞接孔110時,第二桿部31係平行於第一側邊402與第二側邊403(即平行於樞接孔110的延伸方向X1)。於此實施例中,第一彈抵舌片43係沿實質上垂直於第一側邊402的方向突出,且第二彈抵舌片44係沿實質上垂直於第二側邊403的方向突出,因此當支撐桿3的第二桿部31穿設於孔座11的樞接孔110時,突出於第一側邊402的第一彈抵舌片43與突出於第二側邊403的第二彈抵舌片44均沿實質上垂直於第二桿部31的方向延伸於第一層結構40。In addition, the circuit board 4 further includes a first resilient tab 43 and a second resilient tab 44. The first resilient tab 43 protrudes from the first side 402 of the first opening 401. The sheet 44 protrudes from the second side 403 of the first opening 401 and is opposite to the first resilient tab 43. It is worth mentioning that an extending direction X1 of the pivot hole 110 of the socket 11 is parallel to the first side 402 and the second side 403, so that when the second rod portion 31 of the support rod 3 is passed through the socket When the hole 110 is pivoted, the second rod portion 31 is parallel to the first side 402 and the second side 403 (ie, parallel to the extending direction X1 of the pivot hole 110). In this embodiment, the first resilient tab 43 protrudes in a direction substantially perpendicular to the first side 402, and the second resilient tab 44 projects in a direction substantially perpendicular to the second lateral 403. Therefore, when the second rod portion 31 of the support rod 3 is disposed through the pivot hole 110 of the socket 11 , the first elastically protruding tongue 43 protruding from the first side 402 and the second protruding from the second side 403 The two resilient tabs 44 each extend in the first layer structure 40 in a direction substantially perpendicular to the second stem portion 31.
進一步地,第一彈抵舌片43相對第一側邊402的一側形成一第一端緣430,第二彈抵舌片44相對第二側邊403之一側形成一第二端緣440,第一端緣430與第二端緣440間定義一切開線45,且切開線45的一端連通於第一開口401。此外,第一層結構40另形成有連通於切開線45的另一端的一破孔404。當第一彈抵舌片43與第二彈抵舌片44不受力時,第一彈抵舌片43與第二彈抵舌片44均未變形而分別與第一層結構40共平面,此時第一彈抵舌片43的第一端緣430鄰靠第二彈抵舌片44的第二端緣440而形成切開線45,而當第一彈抵舌片43與第二彈抵舌片44受力時,第一彈抵舌片43與第二彈抵舌片44係可分別向第一開口401的第一側邊402與第二側邊403彎折,此時切開線45係可擴大而形成一通道。於此實施例中,第一開口401實質上為一矩形開口,且破孔404實質上為一圓形開口,但本發明不受此限。Further, a first end edge 430 is formed on a side of the first resilient tab 43 opposite the first side 402, and a second edge 440 is formed on a side of the second resilient tab 44 opposite the second side 403. An open line 45 is defined between the first end edge 430 and the second end edge 440, and one end of the cut line 45 is connected to the first opening 401. In addition, the first layer structure 40 is further formed with a hole 404 that communicates with the other end of the slit line 45. When the first resilient tab 43 and the second resilient tab 44 are unstressed, the first resilient tab 43 and the second resilient tab 44 are undeformed and are coplanar with the first layer 40, respectively. At this time, the first end edge 430 of the first resilient tab 43 abuts against the second end edge 440 of the second resilient tab 44 to form an incision line 45, and when the first resilient tab 43 is in contact with the second spring When the tongue piece 44 is pressed, the first elastic tongue piece 43 and the second elastic tongue piece 44 are respectively bent toward the first side 402 and the second side 403 of the first opening 401, and the cutting line 45 is cut at this time. The system can be expanded to form a channel. In this embodiment, the first opening 401 is substantially a rectangular opening, and the hole 404 is substantially a circular opening, but the invention is not limited thereto.
除此之外,第二層結構41形成有一第二開口410,第二開口410涵蓋孔座11、第一彈抵舌片43與第二彈抵舌片44,第三層結構42形成有對應第二開口410的一第三開口420,即第三開口420亦涵蓋孔座11、第一彈抵舌片43與第二彈抵舌片44,因此當第一彈抵舌片43與第二彈抵舌片44分別向第一開口401的第一側邊402與第二側邊403彎折時,第一彈抵舌片43與第二彈抵舌片44可順利彎折進入第二開口410與第三開口420,即第二開口410與第三開口420涵蓋第一彈抵舌片43與第二彈抵舌片44的結構設計可確保第一彈抵舌片43與第二彈抵舌片44在向第一開口401的第一側邊402與第二側邊403彎折時不會受到電路板4結構(即第二層結構41與第三層結構42)的干涉,此外第二開口410與第三開口420涵蓋孔座11的結構設計可使底板1樞接孔110依序經由第三開口420、第二開口410及第一開口401突出於電路板4,使支撐桿3的第二桿部31能穿設於孔座11的樞接孔110。In addition, the second layer structure 41 is formed with a second opening 410. The second opening 410 covers the hole holder 11, the first elastic-engaging tongue 43 and the second elastic-resisting tongue 44, and the third layer structure 42 is formed correspondingly. A third opening 420 of the second opening 410, that is, the third opening 420 also covers the socket 11, the first resilient tab 43 and the second resilient tab 44, so when the first resilient tab 43 and the second When the elastic abutting tabs 44 are respectively bent toward the first side 402 and the second side 403 of the first opening 401, the first resilient tab 43 and the second resilient tab 44 can be smoothly bent into the second opening. 410 and the third opening 420, that is, the second opening 410 and the third opening 420 cover the structural design of the first resilient tab 43 and the second resilient tab 44 to ensure that the first resilient tab 43 and the second resilient projection When the first side 402 and the second side 403 of the first opening 401 are bent, the tongue 44 is not interfered by the structure of the circuit board 4 (ie, the second layer structure 41 and the third layer structure 42). The second opening 410 and the third opening 420 cover the structural design of the socket 11 so that the bottom plate 1 pivoting hole 110 protrudes from the circuit board 4 through the third opening 420, the second opening 410 and the first opening 401 in sequence, so that The second rod portion 31 of the support rod 3 can pass through the pivot hole 110 of the socket 11.
請參閱第2圖至第6圖,第6圖為本發明實施例按鍵裝置1000的剖面示意圖。如第2圖至第6圖所示,當支撐桿3安裝於底板1上時,支撐桿3的第二桿部31係穿設於孔座11的樞接孔110,此時第二桿部31會壓抵第一彈抵舌片43與第二彈抵舌片44,使第一彈抵舌片43與第二彈抵舌片44向第一開口401的第一側邊402與第二側邊403彎折變形,且第二桿部31可經由切開線45進入第一層結構40內,在第一彈抵舌片43與第二彈抵舌片44變形的同時,第一彈抵舌片43與第二彈抵舌片44亦共同彈性支撐支撐桿3的第二桿部31往上抵接樞接孔110的上壁,以消除第二桿部31與樞接孔110配合時的餘隙,進而降低按鍵裝置1000於按壓時的噪音。Please refer to FIG. 2 to FIG. 6 . FIG. 6 is a schematic cross-sectional view of a key device 1000 according to an embodiment of the present invention. As shown in FIG. 2 to FIG. 6 , when the support rod 3 is mounted on the bottom plate 1 , the second rod portion 31 of the support rod 3 is threaded through the pivot hole 110 of the socket 11 , and the second rod portion is at this time. 31 will be pressed against the first elastic tongue 43 and the second elastic tongue 44, so that the first elastic tongue 43 and the second elastic tongue 44 are directed to the first side 402 and the second opening 401 of the first opening 401 The side edge 403 is bent and deformed, and the second rod portion 31 can enter the first layer structure 40 via the slit line 45, and the first spring-loaded tongue piece 43 and the second spring-resistant tongue piece 44 are deformed simultaneously The second piece 31 of the support rod 3 is elastically supported by the second rod portion 31 of the support rod 3 to abut the upper wall of the pivot hole 110 to eliminate the cooperation of the second rod portion 31 with the pivot hole 110. The clearance further reduces the noise of the button device 1000 when pressed.
值得一提的是,切開線45係對應於支撐桿3的第二桿部31的幾何中心,即切開線45係對齊於支撐桿3的第二桿部31的中心軸線,使得第二桿部31能平均壓抵第一彈抵舌片43與第二彈抵舌片44。如此一來,第一彈抵舌片43與第二彈抵舌片44便能產生均等的變形而提供支撐桿3的第二桿部31均勻的支撐力。It is worth mentioning that the incision line 45 corresponds to the geometric center of the second rod portion 31 of the support rod 3, that is, the incision line 45 is aligned with the central axis of the second rod portion 31 of the support rod 3, so that the second rod portion 31 can be pressed against the first bullet abutting tab 43 and the second resilient tab 44. In this way, the first elastic-engaging tongue piece 43 and the second elastic-resisting tongue piece 44 can be uniformly deformed to provide a uniform supporting force of the second rod portion 31 of the support rod 3.
相較於先前技術,當本發明按鍵裝置的支撐桿安裝於底板上時,支撐桿的第二桿部係穿設於孔座的樞接孔,此時第二桿部會壓抵第一彈抵舌片與第二彈抵舌片,使第一彈抵舌片與第二彈抵舌片彎折變形,在第一彈抵舌片與第二彈抵舌片變形的同時,第一彈抵舌片與第二彈抵舌片亦共同彈性支撐支撐桿的第二桿部往上抵接樞接孔的上壁,以消除第二桿部與樞接孔配合時的餘隙,進而降低按鍵裝置於按壓時的噪音。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。Compared with the prior art, when the support rod of the button device of the present invention is mounted on the bottom plate, the second rod portion of the support rod passes through the pivot hole of the hole holder, and the second rod portion is pressed against the first bullet.
