Referring to Figures 1 to 3, the waterproof button structure 2 of the present invention is applied. The mobile phone 1 is taken as an example, and the following description is based on the direction in which the waterproof button structure 2 is pressed and pressed downward. The main components of the mobile phone 1 of the present embodiment include a waterproof button structure 2 and a casing 3. The structure of each component and the relationship between the components are as follows: First, referring to Figures 1 to 2, the waterproof button structure 2 includes a button 10 And an elastic member 20, wherein the button 10 has a pressing portion 11 and a connecting rod 12, the pressing portion 11 is for the user to press and the connecting rod 12 is formed by extending from the bottom surface of the pressing portion 11. A small diameter portion 13 is recessed in the outer peripheral surface of the connecting rod 12 near the one end of the pressing portion 11, and the small diameter portion 13 has a circular cross section and a diameter D.
彈性件20概呈中空圓錐狀並且由上到下漸次擴大，彈性件20的上下二端具有直線相通的一上開口21與一下開口22。上開口21的外緣設有一密封環部23以供按鍵10的連接桿12插入，並且當按鍵10插入彈性件20時，連接桿12可通過並凸出下開口22。密封環部23的橫剖面概呈圓形而具有較大的厚度，密封環部23的內緣在未受外力時的截面形狀為圓形且內徑定義為d，並且密封環部23的內徑d不大於小徑部13的直徑D。另外，下開口22的外緣也選擇性地連接一呈平板狀的組裝部24，本領域技術人員可視實際需要更改組裝部24的形狀或是不設置組裝部24。 The elastic member 20 has a hollow conical shape and gradually expands from top to bottom. The upper and lower ends of the elastic member 20 have an upper opening 21 and a lower opening 22 which are in direct communication with each other. The outer edge of the upper opening 21 is provided with a seal ring portion 23 for the insertion of the connecting rod 12 of the button 10, and when the button 10 is inserted into the elastic member 20, the connecting rod 12 can pass through and protrude from the lower opening 22. The cross section of the seal ring portion 23 is substantially circular and has a large thickness, and the inner edge of the seal ring portion 23 is circular in cross section when the external force is not applied, and the inner diameter is defined as d, and the inside of the seal ring portion 23 is The diameter d is not larger than the diameter D of the small diameter portion 13. In addition, the outer edge of the lower opening 22 is also selectively connected to a flat assembly portion 24. The person skilled in the art may change the shape of the assembly portion 24 or the assembly portion 24 as needed.
值得一提的是，本發明並不需要限制密封環部23與小徑部13的截面形狀均為圓形，只要密封環部23的內緣與小徑部13的外周是相對應的互補形狀即可，因此在密封環部23與小徑部13的截面形狀非圓形時，只要密封環部二相對內側之間距不大於小徑部二相對外側之間距即可達成相同的緊配合效果。 It is to be noted that the present invention does not need to limit the cross-sectional shape of the seal ring portion 23 and the small-diameter portion 13 to be circular, as long as the inner edge of the seal ring portion 23 and the outer circumference of the small-diameter portion 13 are complementary shapes. Therefore, when the cross-sectional shape of the seal ring portion 23 and the small-diameter portion 13 is not circular, the same tight fitting effect can be achieved as long as the distance between the opposite inner sides of the seal ring portion 2 is not larger than the distance between the opposite outer sides of the small-diameter portion.
殼體3內部裝設有手機1的一電路板(圖未示)並且殼體3的側 邊設有一安裝座4，安裝座4的位置對應於電路板的一開關件(圖未示)。本實施例是以按鍵10作為電源開關為例，其中開關件為一金屬簧片(metal dome)，並且彈性件20藉由組裝部24而組裝在安裝座4上。整個防水按鍵結構2可在一按壓位置與一鬆開位置之間移動，當使用者按壓按鍵10，進而壓縮彈性件20而使按鍵10位於按壓位置時(如第4圖)，連接桿12向下壓抵開關件並且電導通開關件，進而使電路板上的電子元件(圖未示)發出一電源訊號；當使用者停止按壓按鍵10而使按鍵10單純受到彈性件20的恢復彈力所驅動，進而向上移動到鬆開位置時(如第3圖)，連接桿12停止壓抵開關件並且沒有電導通開關件，使電子元件不再發出電源訊號。因此，使用者可以藉由開關件的電導通狀態來加以控制電源訊號的發出與否，進而開啟或是關閉手機1的電源，並且彈性件20的壓縮與恢復提供了使用者足夠的按壓行程，藉以加強按壓手感與強度。 A circuit board (not shown) of the mobile phone 1 is mounted inside the casing 3 and the side of the casing 3 is A mounting seat 4 is disposed on the side, and the position of the mounting seat 4 corresponds to a switch member (not shown) of the circuit board. In this embodiment, the button 10 is used as a power switch. The switch member is a metal dome, and the elastic member 20 is assembled on the mount 4 by the assembly portion 24. The entire waterproof button structure 2 can be moved between a pressing position and a releasing position. When the user presses the button 10 and compresses the elastic member 20 to place the button 10 in the pressing position (as shown in FIG. 4), the connecting rod 12 is oriented. Pressing the switch member and electrically conducting the switch member, thereby causing an electronic component (not shown) on the circuit board to emit a power signal; when the user stops pressing the button 10, the button 10 is simply driven by the recovery elastic force of the elastic member 20. And then moving up to the release position (as shown in Fig. 3), the connecting rod 12 stops pressing against the switch member and there is no electrical conduction switch member, so that the electronic component no longer emits a power signal. Therefore, the user can control whether the power signal is emitted or not by the electrical conduction state of the switch member, thereby turning on or off the power of the mobile phone 1, and the compression and recovery of the elastic member 20 provides the user with sufficient pressing stroke. In order to strengthen the feel and strength of the press.
使用上，當手機1被潑到水時，由於密封環部23在未受外力時的內徑d是小於小徑部13的直徑D，因此當按鍵10的連接桿12插入密封環部23並使密封環部23定位於小徑部13時，密封環部23將處於被小徑部13的外周面擴大的狀態。屆時，密封環部23的恢復彈力會緊密地壓抵小徑部13的外周面，進而有效地防止水分經由防水按鍵結構2的間隙進入殼體3內部。 In use, when the mobile phone 1 is splashed with water, since the inner diameter d of the seal ring portion 23 when it is not subjected to an external force is smaller than the diameter D of the small diameter portion 13, when the connecting rod 12 of the button 10 is inserted into the seal ring portion 23 When the seal ring portion 23 is positioned at the small diameter portion 13, the seal ring portion 23 is in a state of being enlarged by the outer peripheral surface of the small diameter portion 13. At this time, the restoring elastic force of the seal ring portion 23 is tightly pressed against the outer peripheral surface of the small-diameter portion 13, thereby effectively preventing moisture from entering the inside of the casing 3 via the gap of the waterproof key structure 2.
須說明的是，本發明防水按鍵結構2並不侷限於應用手機電源的開啟或關閉，其亦可改為應用於手機的音量調整按鍵，或是另外搭配其他的連動結構來作為手機電池的輔助拔除按鍵，以及其他的功能開關。 It should be noted that the waterproof button structure 2 of the present invention is not limited to the opening or closing of the mobile phone power supply, and may be applied to the volume adjustment button of the mobile phone, or may be combined with other linkage structures as an auxiliary for the mobile phone battery. Remove buttons and other function switches.
最後，必須再次說明的是，本發明於前述實施例中所揭露的構成元件僅為舉例說明，並非用來限制本案之範圍，舉凡其他易於思及的 結構變化，或與其他等效元件的替代變化，亦應為本案之申請專利範圍所涵蓋。 Finally, it must be noted that the constituent elements disclosed in the foregoing embodiments of the present invention are merely illustrative and are not intended to limit the scope of the present invention.
