Description

按鍵結構及按鍵裝置 Button structure and button device

本申請涉及一種按鍵結構及包括該按鍵結構的按鍵裝置。 The present application relates to a key structure and a key device including the key structure.

常見鍵盤與遊戲手柄的按鍵結構分為“橡膠墊圈(Rubber Dome)+薄膜開關”與“機構式開關”兩種，其原理均為使用者按壓按鍵帽，按鍵帽的柱塞結構向下壓橡膠墊圈或機構式開關，通過橡膠墊圈或機械式開關結構變形從而產生按壓手感，進而觸碰到下面的薄膜開關，產生導通(On)的電氣訊號，傳達使用者的指令。 Common keyboard and gamepad button structures are divided into two types: "Rubber Dome + Membrane Switch" and "Mechanical Switch". The principle is that the user presses the button cap, and the plunger structure of the button cap presses the rubber down. The washer or mechanical switch deforms the structure of the rubber washer or mechanical switch to produce a pressing feel, and then touches the membrane switch below to generate an electrical signal of conduction (On) to convey the user's command.

傳統按鍵設計下，每一次按壓按鍵與按鍵釋放(回彈)的力量都由橡膠墊圈或彈簧決定，其力量非常相近。但在遊戲場景或某些特殊情境上，需要即時調整按鍵的按壓力量和/或回彈力量(時間)，以達到強化遊戲和改善體驗的目的，則傳統按鍵的設計需要進一步改善。 Under the traditional button design, the strength of each button press and button release (rebound) is determined by the rubber washer or spring, and the strength is very similar. However, in game scenes or some special situations, it is necessary to adjust the pressing force and/or rebounding force (time) of the button in real time to achieve the purpose of enhancing the game and improving the experience, so the design of the traditional button needs to be further improved.

有鑑於此，本申請提出一種可動態調整按壓力量和回彈時間的按鍵結構。 In view of this, the present application proposes a key structure that can dynamically adjust the pressing force and rebound time.

As such, variations in the shapes of the illustrations as a result of manufacturing processes and/or tolerances are to be expected. Thus, embodiments of the present application should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing.

請參閱圖1，圖1為先前技術中薄膜式鍵盤的彈力曲線圖。橫軸代表壓下/釋放按鍵帽的行程距離，單位為毫米(mm)。縱軸代表手指壓下按鍵帽所要花費的力量或按鍵回彈時手指所感受到的力量，單位為克力(gf)。上方曲線1代表按鍵帽壓下去的變化過程，而下方曲線2則是按鍵帽壓下後再彈回原狀的變化過程。座標原點為起始點，F1為峰值點，F2為接觸點，F3為回彈點，F4為最高回彈點，F5為結束點。 Please refer to FIG. 1 . FIG. 1 is a spring force curve diagram of a membrane keyboard in the prior art. The horizontal axis represents the travel distance of pressing/releasing the keycap, in millimeters (mm). The vertical axis represents the force it takes for the finger to depress the keycap or the force felt by the finger when the key rebounds, in grams-force (gf). The upper curve 1 represents the change process when the keycap is pressed down, while the lower curve 2 is the change process when the keycap is pressed down and then bounces back to its original shape. The coordinate origin is the starting point, F1 is the peak point, F2 is the contact point, F3 is the rebound point, F4 is the highest rebound point, and F5 is the end point.

在沒壓下按鍵帽時，手指的力道位於左下角座標原點的位置。當開始壓下按鍵時，曲線1便會往右上方爬，手指的力道越強，按鍵帽壓下去的距離就會變長。當彈性件的彈性變形部(也另稱為彈力壁)無法承受力道時，便開始變形往下凹陷，峰值點F1所承受的力道便是使用者感受最明顯的下壓力道。從F1點開始，彈性件兩側的彈性變形部因為承受不了而開始彎曲，手指感受到的下壓力道會變輕，因此曲線1往右下方走。當抵達接觸點F2時，彈性件接觸到薄膜開關，進而形成通路讓信號通過。在接觸點F2之後因為按鍵帽已經到底了，所以後來的行程距離會受到彈性件壓縮變形的阻力，手指花的力道也最大，因此結束點F5的力道值可能會非常大。 When the button cap is not pressed, the force of the finger is located at the origin of the coordinates in the lower left corner. When you start to press the button, the curve 1 will climb to the upper right. The stronger the force of the finger, the longer the distance the button cap will be pressed down. When the elastic deformation part (also called the elastic wall) of the elastic member cannot withstand the force, it begins to deform and sag downwards. The force borne by the peak point F1 is the most obvious downward force felt by the user. Starting from point F1, the elastic deformation parts on both sides of the elastic member begin to bend because they cannot withstand it, and the downforce felt by the fingers will become lighter, so curve 1 goes down to the right. When reaching the contact point F2, the elastic member contacts the membrane switch, thereby forming a path for the signal to pass through. After the contact point F2, because the button cap has already bottomed out, the subsequent stroke distance will be resisted by the compression deformation of the elastic member, and the force of the fingers is also the largest, so the force value at the end point F5 may be very large.

曲線2記錄手指鬆開後的彈力變化圖，因此方向是從右往左。彈性件在受到擠壓變形的期間已經累積了不少力量，所以當按鍵結構被放開時，這些力量便一下子就全部釋放出來(亦即手指感受到的回彈力)，從F5點直接滑到回彈點F3。當彈性件回到被壓到底的形狀後，便會進行反彈回到原始狀態，此時的回饋力道會變高，直到彈性件的彈性變形部回復原狀。在這過程反彈的力道也會變小，而來到了最高回彈點F4，之後曲線再慢慢地回到起始點(座標原點)。 Curve 2 records the change of elastic force after the finger is released, so the direction is from right to left. The elastic part has accumulated a lot of force during the period of being squeezed and deformed, so when the button structure is released, all the force will be released at once (that is, the rebound force felt by the finger), and slide directly from the F5 point. Go to rebound point F3. When the elastic member returns to the shape of being pressed to the bottom, it will bounce back to the original state, and the feedback force at this time will become higher until the elastically deformed portion of the elastic member returns to its original state. During this process, the strength of the rebound will also become smaller, and the highest rebound point F4 is reached, and then the curve will slowly return to the starting point (the origin of the coordinates).

受限於彈性件的材質等因素，現有的按鍵結構無法即時調整按鍵的按壓力量和/或回彈力量(時間)。因此本申請提供一種可動態調整按壓力量和回彈時間的按鍵結構和包括該按鍵結構的按鍵裝置。 Due to factors such as the material of the elastic member, the existing button structure cannot adjust the pressing force and/or rebound force (time) of the button in real time. Therefore, the present application provides a key structure capable of dynamically adjusting the pressing force and rebound time and a key device including the key structure.

下面結合附圖，對本申請的一些實施方式作詳細說明。在不衝突的情況下，下述的實施方式及實施方式中的特徵可以相互組合。 Some implementations of the present application will be described in detail below in conjunction with the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

第一實施例 first embodiment

請參閱圖2，本申請一實施方式提供一種按鍵裝置1，其包括多個按鍵結構100。按鍵裝置1可應用於筆記型電腦、平板電腦、電視遙控器、桌上型電腦等電子裝置。然而，按鍵裝置1的應用場所並不限於上述範疇。本實施例中，所述按鍵裝置1為薄膜式鍵盤。 Referring to FIG. 2 , an embodiment of the present application provides a key device 1 , which includes a plurality of key structures 100 . The button device 1 can be applied to electronic devices such as notebook computers, tablet computers, TV remote controllers, and desktop computers. However, the application of the key device 1 is not limited to the above-mentioned category. In this embodiment, the key device 1 is a membrane keyboard.

為了簡化說明，圖3和圖4僅顯示了單一的按鍵結構100，圖2薄膜式鍵盤的其餘按鍵結構100亦可採取相同的設計。如圖3和圖4所示，本申請一實施方式提供的按鍵結構100包括按鍵帽10、第一磁性件20、彈性件30、薄膜開關40、第二磁性件50和電路板60。請參閱圖5，按鍵帽10包括按壓部11和與所述按壓部11連接的延伸部12，第一磁性件20固定設置於所述延伸部12上。薄膜開關40遠離所述第一磁性件20設置，彈性件30抵持於所述第一磁性件20與所述薄膜 開關40之間。第二磁性件50設於薄膜開關40與電路板60之間，第二磁性件50通電後可產生磁性從而與第一磁性件20之間產生吸力或斥力。 To simplify the description, FIG. 3 and FIG. 4 only show a single key structure 100, and the other key structures 100 of the membrane keyboard in FIG. 2 can also adopt the same design. As shown in FIGS. 3 and 4 , a key structure 100 provided by an embodiment of the present application includes a key cap 10 , a first magnetic component 20 , an elastic component 30 , a membrane switch 40 , a second magnetic component 50 and a circuit board 60 . Referring to FIG. 5 , the keycap 10 includes a pressing portion 11 and an extension portion 12 connected to the pressing portion 11 , and the first magnetic member 20 is fixedly disposed on the extension portion 12 . The membrane switch 40 is set away from the first magnetic member 20, and the elastic member 30 is held against the first magnetic member 20 and the membrane. Switch between 40. The second magnetic part 50 is disposed between the membrane switch 40 and the circuit board 60 , and the second magnetic part 50 can generate magnetism after being energized so as to generate an attractive or repulsive force with the first magnetic part 20 .

第一磁性件20可為環狀的永久性磁鐵，第二磁性件50可為感應線圈。優選的，感應線圈與環狀的第一磁性件20同軸設置，以使感應線圈通電後與第一磁性件20之間的吸力或斥力最大。 The first magnetic component 20 can be a ring-shaped permanent magnet, and the second magnetic component 50 can be an induction coil. Preferably, the induction coil is arranged coaxially with the ring-shaped first magnetic member 20 , so that the attraction or repulsion between the induction coil and the first magnetic member 20 is maximized after being energized.

當按鍵帽10受壓帶動第一磁性件20朝向第二磁性件50移動時，根據冷次定律(Lenz’s Law)，第二磁性件50(感應線圈)受磁場變化產生感應電流。若進一步通上與該感應電流方向相同的電流，則第二磁性件50產生與第一磁性件20相同的磁極(與第一磁性件20相斥，需增加按壓力量)；若進一步通上與該感應電流方向相反的電流，則第二磁性件50產生與第一磁性件20相反的磁極(與第一磁性件20相吸，可減少按壓力量)。按鍵釋放(回彈)過程，根據楞次定率，感應線圈會產生感應電流產生與第一磁性件20相吸的磁場，故可以針對感應線圈進行以下動作，動態對按鍵帽10產生不同的作用：對感應線圈通上與感應電流方向相同的電流，則對於按鍵帽10呈現相吸的現象，可延遲按鍵帽10恢復到原來位置的時間(延長回彈時間)；對感應線圈通上與感應電流方向相反的電流，形成相斥磁場，可以加快按鍵帽10歸位元，縮短反應時間。如此，可根據遊戲內容或情境需要，通過調整感應線圈的電流方向與大小，可以動態調整壓力曲線，調整按鍵結構100按壓的力量與釋放回彈的時間。 When the keycap 10 is pressed to drive the first magnetic member 20 to move toward the second magnetic member 50, according to Lenz’s Law, the second magnetic member 50 (induction coil) is subjected to a magnetic field change to generate an induced current. If the electric current identical with this induction current direction is passed on further, then the second magnetic part 50 produces the magnetic pole identical with the first magnetic part 20 (with the first magnetic part 20 repelling, needs to increase pressing force); If the direction of the induced current is opposite, the second magnetic member 50 will generate a magnetic pole opposite to that of the first magnetic member 20 (it will attract the first magnetic member 20 to reduce the pressing force). During the key release (rebound) process, according to the Lenz law, the induction coil will generate an induction current to generate a magnetic field that attracts the first magnetic member 20, so the following actions can be performed on the induction coil to dynamically produce different effects on the key cap 10: Passing the current with the same direction as the induction current to the induction coil will cause the phenomenon of mutual attraction for the key cap 10, which can delay the time for the key cap 10 to return to its original position (prolong the rebound time); pass the induction coil with the induction current The currents in opposite directions form a repelling magnetic field, which can accelerate the return of the key cap 10 and shorten the response time. In this way, the pressure curve can be dynamically adjusted by adjusting the current direction and magnitude of the induction coil according to the game content or situational needs, and the pressing force of the button structure 100 and the time for releasing the rebound can be adjusted.

例如，遊戲軟體設定好參數或是選用模式，當按鍵帽10受壓向下運動，按鍵帽10上的第一磁性件20(磁鐵)對第二磁性件50(感應線圈)產生感應電流，第二磁性件50據前一個步驟選擇的模式，增加與感應電流方向相同的電流(產生相同磁極，相斥力量)或與感應電流方向相反的電流(產生相反磁極，相吸力量)。在遊戲中若主角呈現受傷、沒體力、中毒或泥濘的路面等狀況，可依遊戲場景即時將按鍵壓力提高，可類比遊戲主角行動不便或是行動 減緩的情況；反之，若主角使用道具體力大增，可即時將按鍵壓力減小。每個玩家喜歡的按壓力量不一樣，有些喜歡稍大的按壓力量，有些則喜歡較輕的力量，則使用者根據可其喜好調整按壓力量。對於按鍵釋放(回彈)過程，遊戲軟體可設定好參數或是選用模式，使第二磁性件50(感應線圈)產生與第一磁性件20相斥的力量，在按鍵帽10釋放後的自由狀態下會加速向上移動，進而減少回復到原始點的時間，讓使用者可以更快進行下一次動作；或是第二磁性件50(感應線圈)產生與第一磁性件20相吸的力量，推遲釋放，延長反應時間。 For example, the game software sets the parameters or selects the mode. When the keycap 10 is pressed and moves downward, the first magnetic part 20 (magnet) on the keycap 10 generates an induced current to the second magnetic part 50 (induction coil). According to the mode selected in the previous step, the two magnetic parts 50 increase the current in the same direction as the induced current (generating the same magnetic pole, mutual repulsion force) or the current in the opposite direction to the induced current (generating opposite magnetic poles, mutual attraction force). In the game, if the protagonist is injured, weak, poisoned or muddy on the road, the button pressure can be increased immediately according to the game scene, which can be compared to the protagonist's inability to move or move On the other hand, if the protagonist uses the prop to increase his physical strength, he can immediately reduce the button pressure. Each player prefers a different pressing force, some prefer a slightly larger pressing force, while others prefer a lighter force, and the user can adjust the pressing force according to his or her preference.

The key cap 10A in this example is substantially the same as the key cap 10 in the first embodiment, including a pressing portion 11A and an extension portion 12A connected to the pressing portion 11A, and the first magnetic member 20A is fixedly arranged on the extension portion 12A superior. The elastic member 30A is supported against an end of the extension portion 12A away from the pressing portion 11A, and the membrane switch 40A is disposed on a side of the elastic member 30A away from the keycap 10A. The structure of the elastic member 30A is substantially the same as that of the elastic member 30 in the first embodiment, which will not be repeated here. The elastic member 30 can be a rubber washer.

Circuit board 60A may be, but is not limited to, a printed circuit board component.

第一磁性件20A可為永久性磁鐵，第二磁性件50A可為感應線圈。當按鍵帽10A受壓帶動第一磁性件20A朝向第二磁性件50A移動時，根據楞次定律(Lenz’s Law)，第二磁性件50A(感應線圈)受磁場變化產生感應電流。若進一步通上與該感應電流方向相同的電流，則第二磁性件50A產生與第一磁性件20A相同的磁極(與第一磁性件20A相斥，需增加按壓力量)；若進一步通上與該感應電流方向相反的電流，則第二磁性件50A產生與第一磁性件20A相反的磁極(與第一磁性件20A相吸，可減少按壓力量)。按鍵釋放(回彈)過程，根據楞次定率，感應線圈會產生感應電流產生相吸的磁場，故可以針對感應線圈進行以下動作，動態對按鍵帽產生不同的作用：對感應線圈通上與感應電流方向相同的電流，則對於按鍵帽10A呈現相吸的現象，可延遲按鍵帽10A恢復到原來位置的時間(延長回彈時間)；對感應線圈通上與感應電流方向相反的電流，形成相斥磁場，可以加快按鍵帽10A歸位元，縮短反應時間。 The first magnetic element 20A can be a permanent magnet, and the second magnetic element 50A can be an induction coil. When the keycap 10A is pressed and the first magnetic member 20A moves toward the second magnetic member 50A, according to Lenz’s Law, the second magnetic member 50A (induction coil) is subjected to a magnetic field change to generate an induced current. If the current with the same direction as the induced current is further passed on, the second magnetic part 50A produces the same magnetic pole as the first magnetic part 20A (to repel the first magnetic part 20A, the pressing force needs to be increased); If the direction of the induced current is opposite, the second magnetic member 50A will generate a magnetic pole opposite to that of the first magnetic member 20A (it will attract the first magnetic member 20A to reduce the pressing force). During the key release (rebound) process, according to the Lenz law, the induction coil will generate an induction current to generate a magnetic field that attracts each other, so the following actions can be performed on the induction coil, and the dynamics will have different effects on the key cap: the induction coil is connected to the induction coil. The current with the same current direction will attract the key cap 10A, which can delay the time for the key cap 10A to return to its original position (prolong the rebound time); pass the current opposite to the induced current direction to the induction coil to form a phase Repelling the magnetic field can speed up the return of the key cap 10A and shorten the response time.
