為更進一步闡述本新型為達到預定目的所採取的技術手段及功效，以下結合附圖及較佳實施例，對本新型的具體實施方式詳細說明。 In order to further explain the technical means and effects of the new model to achieve the intended purpose, the specific implementation of the new model will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

請參照圖1與圖2，一種按鍵開關用撥動式有聲無聲切換機構，包括一基座1、及設置於該基座1上並上下移動的一按壓件2，在該按壓件2上設置有一按壓凸塊21，在該基座1上形成有一導引斜面11，在該基座1上設置有一彈性件3，該彈性件3一端位於導引斜面11上方，在該基座1上設置有一撥動切換件4，該撥動切換件4帶動該彈性件3一端在處於該按壓凸塊21下方與遠 離該按壓凸塊21下方之間切換。 Please refer to Fig. 1 and Fig. 2, a toggle type soundless switching mechanism for a key switch, comprising a base 1, and a pressing member 2 arranged on the base 1 and moving up and down, a pressing protrusion 21 is arranged on the pressing member 2, a guiding slope 11 is formed on the base 1, an elastic member 3 is arranged on the base 1, one end of the elastic member 3 is located above the guiding inclined surface 11, a toggle switching member 4 is arranged on the base 1, and the toggle switching member 4 drives the elastic One end of piece 3 is located below the pressing bump 21 and far away From the bottom of the pressing bump 21 to switch.

本實施例由該彈性件3與該撥動切換件4進行配合，通過對該撥動切換件4進行撥動使該彈性件3一端在處於該按壓凸塊21下方與遠離該按壓凸塊21下方之間切換，從而實現按壓有聲與按壓無聲兩種功能的切換，滿足用戶的不同需求。 In this embodiment, the elastic member 3 cooperates with the toggle switching member 4, and by toggling the toggle switch 4, one end of the elastic member 3 is switched between being below the pressing bump 21 and being away from the pressing bump 21, so as to realize switching between two functions of pressing with sound and pressing without sound, and meeting different needs of users.

具體的，當撥動該撥動切換件4向遠離該按壓凸塊21方向移動時，該撥動切換件4作用於該彈性件3一端，使該彈性件3一端朝遠離該按壓凸塊21方向移動，則該彈性件3一端離開該按壓凸塊21下方，即該彈性件3一端發生了彈性形變，如圖4、圖5與圖10所示，此時，向下按壓該按壓件2，該按壓件2不會作用於該彈性件3，不會發出聲音，因此，實現按壓無聲功能。當應用于按鍵開關上時，按鍵開關處於無聲狀態。 Specifically, when the toggle switching member 4 is moved away from the pressing projection 21, the toggle switching member 4 acts on one end of the elastic member 3, so that one end of the elastic member 3 moves away from the pressing projection 21, and then one end of the elastic member 3 leaves the bottom of the pressing projection 21, that is, elastic deformation occurs at one end of the elastic member 3, as shown in Figures 4, 5 and 10. 3. There will be no sound, so the function of pressing silently is realized. When applied to a key switch, the key switch is silent.

當撥動該撥動切換件4向該按壓凸塊21方向移動時，該撥動切換件4對該彈性件3一端的作用力減小或消失，該彈性件3一端在自身彈性恢復力作用下復位，向該按壓凸塊21下方移動，最終處於該按壓凸塊21下方，如圖6、圖7與圖11所示，此時，向下按壓該按壓件2，該按壓件2作用於該彈性件3，發出聲音，因此，實現按壓發聲功能。當應用于按鍵開關上時，按鍵開關處於有聲狀態。 When the toggle switch 4 is moved to the direction of the pressing projection 21, the force exerted by the toggle switch 4 on one end of the elastic member 3 decreases or disappears, and the one end of the elastic member 3 resets under the action of its own elastic restoring force, moves below the pressing projection 21, and finally is below the pressing projection 21, as shown in Fig. . When applied to a key switch, the key switch is in a sound state.

具體的發聲原理為：在向下按壓該按壓件2的過程中，該按壓件2上的按壓凸塊21隨著下移，該按壓凸塊21向下作用於該彈性件3一端，該彈性件3一端下移，當該彈性件3一端下移到碰到該基座1上的導引斜面11時，沿著該導引斜面11向外滑 動，直到該彈性件3一端脫離該按壓凸塊21，此時手會感覺到按壓力有明顯變小，從而產生手感；同時該按壓凸塊21回彈復位，敲打到該基座1、按壓件2和/或該撥動切換件4上產生聲音。 The specific sounding principle is: in the process of pressing down the pressing member 2, the pressing protrusion 21 on the pressing member 2 moves downward, and the pressing protrusion 21 acts downward on one end of the elastic member 3, and one end of the elastic member 3 moves downward. Move until one end of the elastic member 3 breaks away from the pressing projection 21, at which time the hand will feel that the pressing force has decreased significantly, thereby producing a hand feeling; at the same time, the pressing projection 21 rebounds and resets, and knocks on the base 1, the pressing member 2 and/or the toggle switching member 4 to produce a sound.

如圖3與圖8所示，所述撥動切換件4上形成有一開槽41，所述彈性件3一端延伸至該開槽41內。在該撥動切換件4處於未撥動的初始狀態時，該彈性件3的一端位於該開槽41內且位於該按壓凸塊21下方，此時，該撥動切換件4對該彈性件3沒有產生作用力或產生的作用力很小；當該撥動撥動切換件4向遠離該按壓凸塊21方向移動時，該開槽41的側壁作用於該彈性件3一端並推動該彈性件3一端離開該按壓凸塊21下方。對該撥動切換件4進行回撥，使其位於初始狀態的位置，此時，該撥動切換件4對該彈性件3的作用力消失或很小，該彈性件3在自身彈性恢復力作用下復位，向該按壓凸塊21下方移動，最終位於該按壓凸塊21下方。由該撥動切換件4的特殊結構設計，實現精准作用於該彈性件3，從而實現按壓有聲與按壓無聲的切換。 As shown in FIG. 3 and FIG. 8 , a slot 41 is formed on the toggle switching member 4 , and one end of the elastic member 3 extends into the slot 41 . When the toggle switch 4 is in the initial state of not toggling, one end of the elastic member 3 is located in the slot 41 and below the pressing projection 21. At this moment, the toggle switch 4 has no or little force on the elastic member 3; Call back the toggle switch 4 so that it is in the initial state position. At this time, the force exerted by the toggle switch 4 on the elastic member 3 disappears or is very small, and the elastic member 3 resets under the action of its own elastic restoring force, moves below the pressing projection 21, and finally locates below the pressing projection 21. Due to the special structural design of the toggle switching member 4, it can precisely act on the elastic member 3, so as to realize switching between pressing with sound and pressing without sound.
