Abstract
一種按鍵結構包含鍵帽、底板、連接於鍵帽與底板之間的升降機構、及設置於鍵帽下方的開關。開關包含座體、固定於座體的固定磁吸件及兩個電氣端子、及可相對於固定磁吸件旋轉或偏轉而設置於座體上的觸發支架及導通支架。固定磁吸件能吸引觸發支架靠近。其中一個電氣端子對應導通支架的接觸部設置。當導通支架露出於座體的按壓部未被鍵帽按壓時，觸發支架抵推導通支架以使接觸部未接觸對應的電氣端子。當按壓部被鍵帽按壓時，導通支架靠近固定磁吸件以使接觸部接觸對應的電氣端子，使得電氣端子導通。A key structure includes a keycap, a bottom plate, a lifting mechanism connected between the keycap and the bottom plate, and a switch disposed below the keycap. The switch includes a base body, a fixed magnetic member fixed to the base body, two electrical terminals, and a trigger bracket and a conduction bracket that can be rotated or deflected relative to the fixed magnetic body and provided on the base body. The fixed magnetic piece can attract the trigger bracket to approach. One of the electrical terminals is provided corresponding to the contact portion of the conducting bracket. When the conductive bracket is exposed on the pressing portion of the base body and is not pressed by the keycap, the trigger bracket is pushed against the conductive bracket so that the contact portion does not contact the corresponding electrical terminal. When the pressing portion is pressed by the keycap, the conducting bracket is close to the fixed magnetic member to make the contact portion contact the corresponding electrical terminal, so that the electrical terminal is conducted.
Description
本發明關於一種按鍵結構，尤指一種具有機械式關開之按鍵結構。The present invention relates to a button structure, and more particularly to a button structure with a mechanical closing mechanism.
傳統具有機械式關開之按鍵結構通常利用鍵帽直接或經由彈性圓突間接觸發開關接點，但不論前述何者觸發機制，觸發開關接點所施之力與使用者按壓鍵帽所施之力直接相關，此將使開關接點承受的接觸力時大時小。此現象除可能造成接點表面過度磨耗而影響接點的接觸電阻，也可能造成連接接點的彈性結構疲乏(例如以懸臂結構等彈性結構產生接點開、關狀態)。因此，這類按鍵結構的開關的使用壽命會隨著使用者按壓施力的習慣而有不同程度的縮短，亦即按鍵結構的使用壽命縮短，且隨著使用時間，使用者於操作上也會感受到開關的靈敏度下降。The traditional button structure with mechanical closing usually uses the keycap to trigger the switch contact directly or indirectly through the elastic round protrusion, but no matter which of the foregoing trigger mechanisms, the force exerted by the trigger switch contact and the force exerted by the user pressing the keycap Directly related, this will make the contact force of the switch contacts larger and smaller. This phenomenon may not only cause excessive wear of the contact surface and affect the contact resistance of the contact, but also cause fatigue of the elastic structure of the connected contact (for example, the contact is opened and closed with an elastic structure such as a cantilever structure). Therefore, the service life of switches with this type of button structure will be shortened to varying degrees with the user's habit of pressing and applying force, that is, the service life of the button structure will be shortened, and the user will also operate with time. Feel the decrease in the sensitivity of the switch.
鑑於先前技術中的問題，本發明提供一種按鍵結構，使用間接觸發的方式導通開關接點，使得鍵帽受到的按壓力與觸發開關接點之力無關，進而達到保護接點的功效；又，因該按鍵結構搭配應用磁吸力，故該按鍵結構能經長時間的操作。In view of the problems in the prior art, the present invention provides a key structure, which uses an indirect triggering method to turn on the switch contacts, so that the pressing force on the keycap is independent of the force of the trigger switch contacts, thereby achieving the effect of protecting the contacts; Because the key structure is matched with the application of magnetic attraction, the key structure can be operated for a long time.
根據本發明之按鍵結構包含一鍵帽、一底板、一升降機構及一開關。該底板設置於該鍵帽下方。該升降機構對應地設置於該底板與該鍵帽之間，該鍵帽經由該升降機構而能相對於該底板上下移動。該開關包含一座體、一固定磁吸件、一觸發支架、一導通支架、一第一電氣端子及一第二電氣端子。該座體相對於該底板固定設置於該鍵帽下方。該固定磁吸件、該第一電氣端子及該第二電氣端子固定設置於該座體上。該觸發支架及該導通支架可旋轉地或可偏轉地設置於該座體上。該觸發支架具有一按壓部、一第一磁吸部及一第一抵推部，該按壓部突出於該座體設置且位於該鍵帽下方，該第一磁吸部與該固定磁吸件之間產生一第一磁吸力。該導通支架具有一接觸部及一第二抵推部，該接觸部與該第一電氣端子相對設置，該第一抵推部與該第二抵推部相對設置。其中，當該按壓部未被按壓時，該第一磁吸力驅使該觸發支架旋向該固定磁吸件，使得該觸發支架經由該第一抵推部抵推該第二抵推部以使該導通支架旋離該固定磁吸件使得該接觸部遠離該第一電氣端子。又，當該鍵帽朝向該底板移動以按壓該按壓部至一設定位置時，該第一抵推部與該第二抵推部分離，該接觸部接觸該第一電氣端子以導通該第一電氣端子與該第二電氣端子。藉此，該接觸部接觸該第一電氣端子之接觸力與該鍵帽受到的按壓力(例如由使用者施加)或該按壓部接受到的按壓力無關，故該接觸部接觸該第一電氣端子之接觸力可被設計，進而達到保護接點的功效。The key structure according to the present invention includes a keycap, a bottom plate, a lifting mechanism and a switch. The bottom plate is disposed below the keycap. The lifting mechanism is correspondingly disposed between the bottom plate and the keycap, and the keycap can move up and down relative to the bottom plate via the lifting mechanism. The switch includes a base, a fixed magnetic member, a trigger bracket, a conducting bracket, a first electrical terminal and a second electrical terminal. The base is fixedly disposed under the keycap with respect to the bottom plate. The fixed magnetic member, the first electrical terminal and the second electrical terminal are fixed on the base. The trigger bracket and the conducting bracket are rotatably or deflectably disposed on the base body. The trigger bracket has a pressing portion, a first magnetic suction portion, and a first pushing portion. The pressing portion protrudes from the seat body and is located below the keycap. The first magnetic suction portion and the fixed magnetic piece A first magnetic attraction is generated therebetween. The conducting bracket has a contact portion and a second pushing portion, the contact portion is opposite to the first electrical terminal, and the first pushing portion is opposite to the second pushing portion. Wherein, when the pressing portion is not pressed, the first magnetic attraction force drives the trigger bracket to rotate toward the fixed magnetic member, so that the trigger bracket pushes the second pushing portion via the first pushing portion to make the trigger The conducting bracket is rotated away from the fixed magnetic member so that the contact portion is away from the first electrical terminal. In addition, when the keycap moves toward the base plate to press the pressing portion to a set position, the first pushing portion is separated from the second pushing portion, and the contact portion contacts the first electrical terminal to conduct the first An electrical terminal and the second electrical terminal. Thereby, the contact force of the contact portion contacting the first electrical terminal is independent of the pressing force (for example, applied by the user) received by the keycap or the pressing force received by the pressing portion, so the contact portion contacts the first electrical terminal. The contact force of the terminals can be designed to protect the contacts.
相對於先前技術，本發明之按鍵結構於作動時，因鍵帽受到的按壓力與觸發開關接點(即電氣端子)之力無關，故具有保護接點的功效，使得該開關的使用壽命將遠較習知技術中機械式關開的使用壽命長，進而使該按鍵結構的使用壽命亦較習知技術中按鍵結構的使用壽命長。Compared with the prior art, when the button structure of the present invention is actuated, the pressing force received by the keycap has nothing to do with the force of the trigger switch contact (ie, the electrical terminal), so it has the effect of protecting the contact, so that the service life of the switch will be The service life of the key switch is much longer than that of the conventional technology, and the service life of the key structure is also longer than that of the key structure in the conventional technology.
關於本發明之優點與精神可以藉由以下的發明詳述及所附圖式得到進一步的瞭解。The advantages and spirit of the present invention can be further understood through the following detailed description of the invention and the accompanying drawings.

A key structure 1 according to an embodiment includes a keycap 12, a bottom plate 14, a lifting mechanism 16, and a switch 18. The bottom plate 14 is disposed below the keycap 12. The lifting mechanism 16 is correspondingly provided between the bottom plate 14 and the keycap 12, and the keycap 12 can move up and down relative to the bottom plate 14 via the lifting mechanism 16. In this embodiment, the lifting mechanism 16 is a scissor foot bracket connected to the connection structure 124 on the lower surface of the cap body 122 of the keycap 12 and the connection structure 144 on the upper surface of the plate 142 of the bottom plate 14; The present invention is not limited to this. For example, a cantilever structure, a telescopic mechanism with a stacked sleeve-like structure, or two separately provided brackets are used to implement a lifting mechanism. The switch 18 includes a base 182, a fixed magnetic member 184, a trigger bracket 186, a conducting bracket 188, a first electrical terminal 190, and a second electrical terminal 192. The base 182 is fixedly disposed below the keycap 12 with respect to the bottom plate 14. In this embodiment, the base 182 is directly fixed on the board 142. For example, the base 182 is embedded in a groove or an opening formed on the board 142, or the base 182 is adhered or fixed (for example, The screw and the hook structure are fixed on the board 142. The fixed magnetic member 184, the first electrical terminal 190 and the second electrical terminal 192 are fixed on the base 182. The trigger bracket 186 and the conducting bracket 188 are rotatably disposed on the base 182. The trigger bracket 186 has a pressing portion 1862, a first magnetic attraction portion 1864, a first end portion 1868, and a first pushing portion 1866. The trigger bracket 186 is rotatably connected to the base 182 with the first end portion 1868. The pressing portion 1862 protrudes from the base 182 and is located below the keycap 12. A first magnetic attraction force F1 is generated between the first magnetic attraction portion 1864 and the fixed magnetic attraction piece 184 (indicated by double arrows in FIG. 5 and FIG. 6). . The conducting bracket 188 has a contact portion 1882, a second magnetic attraction portion 1884, a second pushing portion 1886, and a second end portion 1888. The contact portion 1882 is disposed opposite to the first electrical terminal 190. The end portion 1888 is rotatably connected to the base 182 as a fulcrum. A second magnetic attraction force F2 is generated between the second magnetic attraction portion 1884 and the fixed magnetic attraction member 184 (indicated by double arrows in FIGS. 5 and 6), and the first pushing portion 1866 and the second pushing portion 1886 are oppositely disposed. .
其中，原則上，第一磁吸力F1對觸發支架186產生之力矩大於第二磁吸力F2對導通支架188產生之力矩，故如圖5所示，當按壓部1862未被按壓時(例如未被鍵帽12按壓)，第一磁吸力F1驅使觸發支架186旋向固定磁吸件184，使得觸發支架186經由第一抵推部1866抵推第二抵推部1886以使導通支架188旋離固定磁吸件184使得接觸部1882遠離第一電氣端子190；換言之，第一電氣端子190與第二電氣端子192未導通(或謂未電性連接)，亦即開關18未被觸發。又，如圖6所示，當鍵帽12朝向底板14移動以按壓按壓部1862時(例如鍵帽12被使用者按壓致使帽體122下表面接觸並向下壓按壓部1862)，觸發支架186受到外力(即對按壓部1862之按壓力)拘束，第一磁吸力F1被該外力克服，觸發支架186旋離固定磁吸件184，第二磁吸力F2驅使導通支架188之第二抵推部1886持續抵接第一抵推部1866，導通支架188旋向固定磁吸件184。Among them, in principle, the moment generated by the first magnetic force F1 to the trigger bracket 186 is greater than the moment generated by the second magnetic force F2 to the conduction bracket 188, so as shown in FIG. 5, when the pressing portion 1862 is not pressed (for example, not Key cap 12 is pressed), the first magnetic force F1 drives the trigger bracket 186 to rotate toward the fixed magnetic member 184, so that the trigger bracket 186 pushes against the second pushing portion 1886 via the first pushing portion 1866 to rotate the conducting bracket 188 away from the fixing The magnetic member 184 keeps the contact portion 1882 away from the first electrical terminal 190; in other words, the first electrical terminal 190 and the second electrical terminal 192 are not conductive (or are not electrically connected), that is, the switch 18 is not triggered. Also, as shown in FIG. 6, when the keycap 12 is moved toward the bottom plate 14 to press the pressing portion 1862 (for example, when the keycap 12 is pressed by the user, the lower surface of the cap body 122 contacts and presses the pressing portion 1862), the bracket 186 is triggered. Subjected to external force (ie, the pressing force on the pressing portion 1862), the first magnetic attraction force F1 is overcome by the external force, triggering the bracket 186 to rotate away from the fixed magnetic member 184, and the second magnetic attraction force F2 drives the second pushing portion of the conducting bracket 188 1886 continues to abut the first pushing portion 1866, and the conducting bracket 188 is rotated toward the fixed magnetic member 184.
當按壓部1862被按壓至一設定位置時(如圖6所示)，接觸部1882接觸第一電氣端子190以導通第一電氣端子190與第二電氣端子192，第一抵推部1866與導通支架188之第二抵推部1886開始分離；換言之，第一電氣端子190與第二電氣端子192導通(或謂電性連接)，亦即開關18被觸發。再續下壓按壓按壓部1862時，第一抵推部1866與第二抵推部1886完全分離；由開關18之結構可知，此時接觸部1882接觸第一電氣端子190之接觸力係決定於第二磁吸力F2，與按壓部1862到的按壓力無關，因此，原則上每次接觸部1882接觸第一電氣端子190之接觸力均相同，故能達到保護接點(電氣端子190、192)的功效。此外，補充說明圖6所示開關18之狀態，其中接觸部1882已接觸第一電氣端子190，而第一抵推部1866仍接觸著第二抵推部1886，但由圖可知觸發支架186仍可繼續被按壓而繼續順時針旋轉而致第一抵推部1866與第二抵推部1886完全分離，故圖6僅是為顯示觸發支架186於自圖5所示之狀態順時針旋轉(因被按壓)的過程中，在未被完全按壓時，即已能使接觸部1882接觸第一電氣端子190，終至被完全按壓時，自然能使第一抵推部1866與第二抵推部1886完全分離，且接觸部1882藉由第二磁吸力F2保持與第一電氣端子190保持接觸。When the pressing portion 1862 is pressed to a set position (as shown in FIG. 6), the contact portion 1882 contacts the first electrical terminal 190 to conduct the first electrical terminal 190 and the second electrical terminal 192, and the first pushing portion 1866 is conductive to The second pushing portion 1886 of the bracket 188 begins to be separated; in other words, the first electrical terminal 190 and the second electrical terminal 192 are turned on (or electrically connected), that is, the switch 18 is triggered. When the pressing portion 1862 is further depressed, the first pushing portion 1866 is completely separated from the second pushing portion 1886. According to the structure of the switch 18, the contact force of the contact portion 1882 to the first electrical terminal 190 is determined by The second magnetic attraction F2 is independent of the pressing force from the pressing portion 1862. Therefore, in principle, the contact force of each contact portion 1882 to the first electrical terminal 190 is the same, so it can reach the protective contact (electrical terminals 190, 192). Effect. In addition, the state of the switch 18 shown in FIG. 6 is additionally explained, in which the contact portion 1882 has contacted the first electrical terminal 190 and the first pushing portion 1866 still contacts the second pushing portion 1886, but it can be seen from the figure that the trigger bracket 186 is still It can continue to be pressed and continue to rotate clockwise so that the first pushing portion 1866 and the second pushing portion 1886 are completely separated, so FIG. 6 is only for showing that the trigger bracket 186 is rotated clockwise in the state shown in FIG. 5 (due to In the process of being pressed), the contact portion 1882 can contact the first electrical terminal 190 when the contact portion 1882 is not fully pressed. When the contact portion 1882 is fully pressed, the first pushing portion 1866 and the second pushing portion can naturally be made. 1886 is completely separated, and the contact portion 1882 is kept in contact with the first electrical terminal 190 by the second magnetic attraction F2.
此外，當按壓鍵帽12之外力消失時，第一磁吸力F1驅使觸發支架186旋向固定磁吸件184並抵推導通支架188旋離固定磁吸件184，使得接觸部1882遠離第一電氣端子190 (亦即第一電氣端子190與第二電氣端子192不導通)，且按壓部1862向上移動以驅使鍵帽12回到原位；換言之，此時第一磁吸力F1亦用以驅使鍵帽12回到原位，或謂第一磁吸力F1亦作為鍵帽12的回復力。另外，於本實施例中，當接觸部1882接觸第一電氣端子190以導通第一電氣端子190及第二電氣端子192時，第一抵推部1866及第二抵推部1886分離，此可確保接觸部1882接觸第一電氣端子190，但於實作上不以此為限，例如基於觸發支架186及導通支架188結構上仍具有一定程度的懸臂彈性特性，可經適當設計以使第一抵推部1866及第二抵推部1886於接觸部1882接觸第一電氣端子190時仍得保持接觸。此外，當觸發支架186及導通支架188均採金屬結構實作時，前述懸臂彈性特性會更明顯。又，於本實施例中，導通支架188的接觸部1882及第二抵推部1886相對於第二磁吸部1884(或導通支架188之一第二端部1888)而言，亦可視為分開的懸臂結構，故於第一抵推部1866與第二抵推部1886相互抵推時，接觸部1882與第二抵推部1886間之連動亦會引入懸臂結構的彈性變形量，此基於一般懸臂梁理論而能了解，不另贅述。In addition, when the external force pressing the keycap 12 disappears, the first magnetic attraction force F1 drives the trigger bracket 186 to rotate toward the fixed magnetic member 184 and pushes the conducting bracket 188 away from the fixed magnetic member 184, so that the contact portion 1882 is far away from the first electrical The terminal 190 (that is, the first electrical terminal 190 and the second electrical terminal 192 are not conductive), and the pressing portion 1862 moves upward to drive the keycap 12 back to the original position; in other words, at this time, the first magnetic attraction F1 is also used to drive the key The cap 12 returns to its original position, or the first magnetic attraction force F1 is also used as the restoring force of the keycap 12. In addition, in this embodiment, when the contact portion 1882 contacts the first electrical terminal 190 to conduct the first electrical terminal 190 and the second electrical terminal 192, the first pushing portion 1866 and the second pushing portion 1886 are separated. It is ensured that the contact portion 1882 contacts the first electrical terminal 190, but it is not limited in practice. For example, based on the structure of the trigger bracket 186 and the conduction bracket 188, it still has a certain degree of cantilever elastic characteristics. It can be appropriately designed to make the first The pushing portion 1866 and the second pushing portion 1886 must remain in contact when the contact portion 1882 contacts the first electrical terminal 190. In addition, when the trigger bracket 186 and the conduction bracket 188 are both implemented with a metal structure, the aforementioned cantilever elastic characteristics will be more obvious. In addition, in this embodiment, the contact portion 1882 and the second pushing portion 1886 of the conducting bracket 188 may be regarded as separate from the second magnetic attraction portion 1884 (or the second end portion 1888 of the conducting bracket 188). Cantilever structure, so when the first pushing portion 1866 and the second pushing portion 1886 push against each other, the linkage between the contact portion 1882 and the second pushing portion 1886 will also introduce the elastic deformation of the cantilever structure, which is based on the general Cantilever beam theory can be understood without further description.
此外，於本實施例中，座體182為一中空結構，其包含一上蓋1822及一下座1824，上蓋1822與下座1824銜接(例如透過卡扣、卡槽銜接)形成一容置空間1826。上蓋1822與下座1824夾持固定磁吸件184。觸發支架186設置於容置空間1826內且其按壓部1862自上蓋1822的通孔1822a朝向鍵帽12伸出上蓋1822(或謂座體182)，其第一端部1868、第一抵推部1866及第一磁吸部1864則位於容置空間1826內。導通支架188設置於容置空間1826內。第一電氣端子190及第二電氣端子192(例如經由上蓋1822與下座1824夾持及/或與下座1824以埋入射出的方式而固定於下座1824)自容置空間1826內伸出座體182。藉此，座體182可提供容置其內的構件保護，亦對電氣端子190、192提供一定程度的防塵效果，有助於電氣端子190、192間導通電阻的維持，亦有助於提升開關18的使用壽命。於實作上，座體182不以保護、防塵為限，故即使座體182以框架結構實作，僅需其具有固定固定磁吸件184的結構、供觸發支架186及導通支架188可旋轉地連接的結構、及供電氣端子190、192固定的結構，同樣能發揮前述開關18作動的效果。此外，於實作上，電氣端子190、192外露出開關18的部分可經由電路板(例如電氣端子190、192焊接至撓性電路板，其可設置於板體142與座體182之間，或設置於板體142下方)或電線以電連接至控制器(例如包含多個按鍵結構1之鍵盤的控制器)。In addition, in this embodiment, the base 182 is a hollow structure, which includes an upper cover 1822 and a lower base 1824. The upper cover 1822 is connected to the lower base 1824 (for example, through a buckle and a slot connection) to form an accommodation space 1826. The upper cover 1822 and the lower seat 1824 hold and fix the magnetic member 184. The trigger bracket 186 is disposed in the accommodating space 1826 and its pressing portion 1862 projects from the through hole 1822a of the upper cover 1822 toward the keycap 12 and the upper cover 1822 (or the seat body 182). The first end portion 1868 and the first pushing portion 1866 and the first magnetic attraction portion 1864 are located in the accommodating space 1826. The conducting bracket 188 is disposed in the accommodating space 1826. The first electrical terminal 190 and the second electrical terminal 192 (for example, sandwiched between the upper cover 1822 and the lower seat 1824 and / or fixed to the lower seat 1824 by embedding the lower seat 1824) protrude from the accommodation space 1826座 体 182 The base 182. In this way, the base 182 can provide protection for the components contained therein, and also provide a certain degree of dust-proof effect on the electrical terminals 190 and 192, which helps to maintain the on-resistance between the electrical terminals 190 and 192, and also helps to improve the switch. 18 useful life. In practice, the base 182 is not limited to protection and dust, so even if the base 182 is implemented in a frame structure, it only needs to have a structure for fixing and fixing the magnetic member 184, and the trigger bracket 186 and the conduction bracket 188 can be rotated. The structure of the ground connection and the structure of the power supply gas terminals 190 and 192 being fixed can also exert the effect of the operation of the switch 18 described above. In addition, in practice, portions of the electrical terminals 190 and 192 that are exposed from the switch 18 may be soldered to a flexible circuit board via a circuit board (for example, the electrical terminals 190 and 192 may be soldered to a flexible circuit board, which may be disposed between the board 142 and the base 182, (Or disposed under the board 142) or a wire for electrically connecting to a controller (such as a controller including a keyboard with a plurality of key structures 1).
此外，於本實施例中，觸發支架186以其一第一端部1868為支點相對於座體182可旋轉的，進一步地，觸發支架186經由第一端部1868可旋轉地設置於上蓋1822的槽1822b中以與上蓋1822樞接。第一磁吸部1864位於第一端部1868及按壓部1862之間且位於固定磁吸件184下方。導通支架188位於觸發支架186與上蓋1822之間並以其第二端部1888為支點相對於座體182可旋轉，使其接觸部1882及第二抵推部1886可與觸發支架186連動；其中，於實作上，第二端部1888可抵靠於上蓋1822的內側表面及/或因第二磁吸力F2而抵靠於固定磁吸件184。第二磁吸部1884位於第二端部1888及接觸部1882之間且位於固定磁吸件184上方。接觸部1882位於第一電氣端子190上方。基於前述各構件配置，以圖5或圖6視角而言，第一磁吸力F1驅使觸發支架186逆時針旋轉，第二磁吸力F2亦驅使導通支架188逆時針旋轉。其中，於實作上，第一抵推部1866及第二抵推部1886之配置以能相互推抵即可，不限於圖中所示之設置及結構。In addition, in this embodiment, the trigger bracket 186 is rotatable relative to the base 182 with a first end portion 1868 as a fulcrum. Further, the trigger bracket 186 is rotatably disposed on the upper cover 1822 via the first end portion 1868. The groove 1822b is pivotally connected to the upper cover 1822. The first magnetic attraction portion 1864 is located between the first end portion 1868 and the pressing portion 1862 and is located below the fixed magnetic attraction member 184. The conducting bracket 188 is located between the trigger bracket 186 and the upper cover 1822 and is rotatable relative to the base 182 with its second end portion 1888 as a fulcrum, so that its contact portion 1882 and the second pushing portion 1886 can be linked with the trigger bracket 186; In practice, the second end portion 1888 may abut against the inner surface of the upper cover 1822 and / or the fixed magnetic member 184 due to the second magnetic attraction F2. The second magnetic attraction portion 1884 is located between the second end portion 1888 and the contact portion 1882 and is located above the fixed magnetic attraction member 184. The contact portion 1882 is located above the first electrical terminal 190. Based on the foregoing component configurations, from the perspective of FIG. 5 or FIG. 6, the first magnetic attraction force F1 drives the trigger bracket 186 to rotate counterclockwise, and the second magnetic attraction force F2 also drives the conduction bracket 188 to rotate counterclockwise. Among them, in practice, the first pushing portion 1866 and the second pushing portion 1886 may be configured to be able to push each other, and is not limited to the arrangement and structure shown in the figure.
此外，於本實施例中，第一電氣端子190及第二電氣端子192相鄰設置且均相對於接觸部1882設置，故接觸部1882於接觸第一電氣端子190的同時，亦接觸第二電氣端子192。於本實施例中，接觸部1882可導電，故當鍵帽12朝向底板14移動以按壓按壓部1862時，第二磁吸力F2驅使導通支架188旋向固定磁吸件184，使得接觸部1882同時接觸第一電氣端子190及第二電氣端子192以導通第一電氣端子190及第二電氣端子192。於實作上，固定磁吸件184可為一磁鐵，導通支架188可為一順磁性金屬件(例如由一順磁性金屬板件，經衝壓成型)，導通支架188對應固定磁吸件184的部位即可作為第二磁吸部1884，此時導通支架188整體即兼具可導電及可磁吸。又，於實作上，導通支架188可僅於接觸部1882形成具可導電的結構，例如透過於接觸部1882的表面上披覆導電層(例如電鍍、化學鍍等)而實現，又例如以埋入射出的方式以一金屬件作為接觸部1882 (並以一順磁性金屬件或磁鐵作為第二磁吸部1884，導通支架188其他部位仍為塑膠件)。In addition, in this embodiment, the first electrical terminal 190 and the second electrical terminal 192 are disposed adjacent to each other and are disposed with respect to the contact portion 1882. Therefore, the contact portion 1882 contacts the second electrical terminal while contacting the first electrical terminal 190. Terminal 192. In this embodiment, the contact portion 1882 can be conductive, so when the keycap 12 moves toward the bottom plate 14 to press the pressing portion 1862, the second magnetic attraction F2 drives the conducting bracket 188 to rotate toward the fixed magnetic member 184, so that the contact portions 1882 are simultaneously The first electrical terminal 190 and the second electrical terminal 192 are contacted to conduct the first electrical terminal 190 and the second electrical terminal 192. In practice, the fixed magnetic member 184 may be a magnet, and the conducting bracket 188 may be a paramagnetic metal member (for example, a paramagnetic metal plate member is stamped and formed). The conducting bracket 188 corresponds to the fixed magnetic member 184. The part can be used as the second magnetic attraction portion 1884. At this time, the conducting bracket 188 as a whole has both conductivity and magnetic attraction. Furthermore, in practice, the conducting bracket 188 can be formed with a conductive structure only at the contact portion 1882, for example, by covering a surface of the contact portion 1882 with a conductive layer (such as electroplating, electroless plating, etc.), and for example, A buried metal part is used as the contact part 1882 (and a paramagnetic metal part or a magnet is used as the second magnetic attraction part 1884, and other parts of the conducting bracket 188 are still plastic parts).
同樣的，觸發支架186亦可為一順磁性金屬件(例如由一順磁性金屬板件，經衝壓成型)，並於該順磁性金屬件之一端部1862a(例如經通孔1822a突出的折彎部位)套上一塑膠蓋1862b以作為按壓部1862。又，觸發支架186可包含一彈簧1862c (以虛線繪示於圖4中)，抵接於塑膠蓋1862b及端部1862a之間，使得當鍵帽12朝向底板14移動以按壓按壓部1862時，塑膠蓋1862a壓縮彈簧1862c。彈簧1862c的彈性變形量可提供鍵帽12額外的按壓行程，彈簧1862c的回彈力對使用者的按壓手感亦有貢獻。另外，觸發支架186亦可採類似於前述以埋入射出的方式形成導通支架188之方式製作，不另贅述。Similarly, the trigger bracket 186 can also be a paramagnetic metal piece (for example, a paramagnetic metal plate piece that is stamped and formed), and bent at one end 1862a (for example, through a through hole 1822a) of the paramagnetic metal piece. (Part) Put a plastic cover 1862b as the pressing portion 1862. In addition, the trigger bracket 186 may include a spring 1862c (shown in dashed lines in FIG. 4), abutting between the plastic cover 1862b and the end portion 1862a, so that when the keycap 12 moves toward the bottom plate 14 to press the pressing portion 1862, The plastic cover 1862a compresses the spring 1862c. The elastic deformation of the spring 1862c can provide an additional pressing stroke of the keycap 12, and the rebound force of the spring 1862c also contributes to the user's pressing feel. In addition, the trigger bracket 186 can also be manufactured in a manner similar to the aforementioned method of forming the conducting bracket 188 in a buried injection manner, and will not be described in detail.
此外，於實作上，按鍵結構1可更包含一輔助磁吸片194 (以虛線繪示於圖4中)對應固定磁吸件184設置於導通支架188上，以加強固定磁吸件184對導通支架188磁吸的能力。同理，按鍵結構1可更包含一輔助磁吸片196 (以虛線繪示於圖4中)對應固定磁吸件184設置於觸發支架186上，以加強固定磁吸件184對觸發支架186磁吸的能力。In addition, in practice, the key structure 1 may further include an auxiliary magnetic piece 194 (shown in dashed lines in FIG. 4) corresponding to the fixed magnetic piece 184 on the conducting bracket 188 to strengthen the fixed magnetic piece 184 pair. The ability to turn on the bracket 188 magnetically. Similarly, the button structure 1 may further include an auxiliary magnetic piece 196 (shown in dashed lines in FIG. 4) corresponding to the fixed magnetic piece 184 disposed on the trigger bracket 186 to strengthen the fixed magnetic piece 184 to the trigger bracket 186. Ability to suck.
請參閱圖7至圖11。根據另一實施例之一按鍵結構3，其與按鍵結構1結構相似，故沿用按鍵結構1之元件符號。按鍵結構3與按鍵結構1的主要差異在於按鍵結構3的開關38的觸發支架386及導通支架388採取不同的結構配置，以實現開關38的觸發。但於開關38中，觸發支架386與導通支架388間相互抵推的作動邏輯仍與開關18中觸發支架186與導通支架188間相互抵推的作動邏輯相同。因此，關於按鍵結構3各構件之其他說明，請參閱前文中按鍵結構1中命名相同的元件之相關說明及其變化說明，不另贅述。Please refer to FIGS. 7 to 11. According to another embodiment of the key structure 3, the structure of the key structure 1 is similar to the structure of the key structure 1, so the component symbols of the key structure 1 are used. The main difference between the key structure 3 and the key structure 1 is that the trigger bracket 386 and the conduction bracket 388 of the switch 38 of the key structure 3 adopt different structural configurations to realize the trigger of the switch 38. However, in the switch 38, the operation logic of the trigger bracket 386 and the conducting bracket 388 against each other is still the same as the operation logic of the trigger bracket 186 and the conduction bracket 188 in the switch 18. Therefore, for other descriptions of the components of the key structure 3, please refer to the related description of the same-named components in the key structure 1 and the description of the changes thereof, and will not be described in detail.
於本實施例中，開關38的觸發支架386具有一彎折部3868。彎折部3868位於觸發支架386的第一抵推部3866及第一磁吸部3864之間。觸發支架386以彎折部3868為支點相對於開關38的座體382可旋轉的；精確地來說，於本實施例中，觸發支架386是以座體382接觸彎折部3868的稜邊為轉動連接部支點而旋轉，但於實作上不以此為限，例如彎折部3868的稜邊非以銳利的邊緣實作，而以小的圓角結構實作，結構邏輯上仍可視為稜邊，座體382以平面(即內側表面)接觸彎折部3868稜邊，當觸發支架386相對於座體382旋轉時，彎折部3868稜邊抵接該平面上轉動，此時，整體而言，觸發支架386仍是以彎折部3868稜邊相對於座體382旋轉。第一磁吸部3864位於觸發支架386的彎折部3868及按壓部3862之間且位於開關38的固定磁吸件184下方。導通支架388以其一端部3888為支點相對於座體382可旋轉的。導通支架388的第二磁吸部3884位於導通支架388的端部3888及接觸部3882之間且位於固定磁吸件184下方。以圖10或圖11視角而言，導通支架388的接觸部3882及第二抵推部3886的投影重疊，故於圖中可將第二抵推部3886的位置亦讀取為接觸部3882的位置。第一磁吸部3864與固定磁吸件184之間產生的第一磁吸力F1 (以雙箭頭表示於圖10及圖11中)驅使觸發支架386順時針旋轉，第二磁吸部3884與固定磁吸件184之間產生的第二磁吸力F2 (以雙箭頭表示於圖10及圖11中)驅使導通支架388逆時針旋轉，第一抵推部3866與導通支架388的第二抵推部3886相對設置。接觸部3882位於開關38的第一電氣端子190與第二電氣端子192下方。當按壓部3862未被按壓時(例如未被鍵帽12按壓)，第一磁吸力F1對觸發支架386產生之力矩大於第二磁吸力F2對導通支架388產生之力矩，故如圖10所示，第一磁吸力F1驅使觸發支架386旋向固定磁吸件184，使得觸發支架386經由第一抵推部3866抵推第二抵推部3886以使導通支架388旋離固定磁吸件384使得接觸部3882遠離第一電氣端子190；換言之，第一電氣端子190與第二電氣端子192未導通(或謂未電性連接)，亦即開關38未被觸發。又，如圖11所示，當鍵帽12朝向底板14移動以按壓按壓部3862時(例如鍵帽12被使用者按壓致使帽體122下表面接觸並向下壓按壓部3862)，觸發支架386受到外力(即對按壓部3862之按壓力)拘束，第一磁吸力F1被該外力克服，觸發支架386旋離固定磁吸件184，第二磁吸力F2驅使導通支架388之第二抵推部3886持續抵接第一抵推部3866，亦驅使導通支架388旋向固定磁吸件184。In this embodiment, the trigger bracket 386 of the switch 38 has a bent portion 3868. The bent portion 3868 is located between the first pushing portion 3866 and the first magnetic attraction portion 3864 of the trigger bracket 386. The trigger bracket 386 is rotatable relative to the base 382 of the switch 38 with the bent portion 3868 as a fulcrum; to be precise, in this embodiment, the trigger bracket 386 is based on the edge of the base 382 contacting the bent portion 3868 as Rotate the fulcrum of the connecting part to rotate, but it is not limited in practice. For example, the edges of the bent portion 3868 are not implemented with sharp edges, but implemented with small rounded corners. The structure can still be regarded as logically. Edge, the base 382 contacts the edge of the bent portion 3868 in a plane (that is, the inner surface). When the trigger bracket 386 is rotated relative to the base 382, the edge of the bent portion 3868 abuts on the plane to rotate. At this time, the whole In other words, the trigger bracket 386 is still rotated relative to the base 382 by the edges of the bent portion 3868. The first magnetic attraction portion 3864 is located between the bent portion 3868 and the pressing portion 3862 of the trigger bracket 386 and is located below the fixed magnetic attraction member 184 of the switch 38. The conducting bracket 388 is rotatable relative to the base 382 with one end 3888 as a fulcrum. The second magnetic attraction portion 3884 of the conduction bracket 388 is located between the end portion 3888 of the conduction bracket 388 and the contact portion 3882 and is located below the fixed magnetic member 184. From the perspective of FIG. 10 or FIG. 11, the projections of the contact portion 3882 of the conducting bracket 388 and the second pushing portion 3886 overlap, so the position of the second pushing portion 3886 can also be read as the contact portion 3882 in the figure. position. The first magnetic attraction force F1 (indicated by the double arrow in FIG. 10 and FIG. 11) generated between the first magnetic attraction portion 3864 and the fixed magnetic attraction piece 184 drives the trigger bracket 386 to rotate clockwise, and the second magnetic attraction portion 3884 and the fixed The second magnetic attraction force F2 (shown by double arrows in FIGS. 10 and 11) generated between the magnetic members 184 drives the conducting bracket 388 to rotate counterclockwise, and the first pushing portion 3866 and the second pushing portion of the conducting bracket 388. 3886 relative setting. The contact portion 3882 is located below the first electrical terminal 190 and the second electrical terminal 192 of the switch 38. When the pressing portion 3862 is not pressed (for example, not by the keycap 12), the moment generated by the first magnetic attraction force F1 to the trigger bracket 386 is greater than the moment generated by the second magnetic attraction force F2 to the conduction bracket 388, as shown in FIG. 10 The first magnetic force F1 drives the trigger bracket 386 to rotate toward the fixed magnetic member 184, so that the trigger bracket 386 pushes against the second pushing portion 3886 via the first pushing portion 3866 to rotate the conducting bracket 388 away from the fixed magnetic piece 384 so that The contact portion 3882 is far from the first electrical terminal 190; in other words, the first electrical terminal 190 and the second electrical terminal 192 are not conductive (or are not electrically connected), that is, the switch 38 is not triggered. In addition, as shown in FIG. 11, when the keycap 12 is moved toward the bottom plate 14 to press the pressing portion 3862 (for example, when the keycap 12 is pressed by the user, the lower surface of the cap body 122 contacts and presses the pressing portion 3862), the bracket 386 is triggered. Constrained by an external force (ie, the pressing force on the pressing portion 3862), the first magnetic force F1 is overcome by the external force, triggering the bracket 386 to rotate away from the fixed magnetic member 184, and the second magnetic force F2 drives the second pushing portion of the conducting bracket 388 3886 continues to abut the first pushing portion 3866, and also drives the conducting bracket 388 to rotate toward the fixed magnetic member 184.
當按壓按壓部3862至一設定距離時(如圖11所示)，接觸部3882 (併參閱圖9)透過同時接觸第一電氣端子190與第二電氣端子192以導通第一電氣端子190與第二電氣端子192；換言之，第一電氣端子190與第二電氣端子192導通(或謂電性連接)，亦即開關38被觸發。當持續按壓按壓部3862時，接觸部3882保持接觸第一電氣端子190以導通第一電氣端子190與第二電氣端子192；而第一抵推部3866與第二抵推部3886分離，且接觸部3882藉由第二磁吸力F2與第一電氣端子190保持接觸。When the pressing portion 3862 is pressed to a set distance (as shown in FIG. 11), the contact portion 3882 (see FIG. 9) contacts the first electrical terminal 190 and the second electrical terminal 192 simultaneously to conduct the first electrical terminal 190 and the first electrical terminal 190. Two electrical terminals 192; in other words, the first electrical terminal 190 and the second electrical terminal 192 are conducting (or electrically connected), that is, the switch 38 is triggered. When the pressing portion 3862 is continuously pressed, the contact portion 3882 remains in contact with the first electrical terminal 190 to conduct the first electrical terminal 190 and the second electrical terminal 192; and the first pushing portion 3866 is separated from the second pushing portion 3886 and contacts The portion 3882 is kept in contact with the first electrical terminal 190 by the second magnetic attraction F2.
此外，於本實施例中，座體382由一本體3820及一順磁性金屬件3821組合而成，使得座體382整體結構類似前述上蓋1822之結構，其中固定磁吸件184設置於本體3820相對的兩側壁與順磁性金屬件3821之間，固定磁吸件184於本體3820內側露出，其他開關38的構件均能穩定地設置於座體382上，故座體382可無需具有如前述下座1824之結構，但於實作上不以此為限。例如座體382由單一構件實作(例如塑膠射出件)，固定磁吸件184固著於座體382上(例如透過卡合、膠黏等方式)。又，例如座體382亦可包含類似前述下座1824之結構，以提升構件保護及防塵效果。於本實施例中，座體382具有一凹槽3822，凹槽3822開口朝下並形成一容置空間3824。導通支架388設置於容置空間3824內。觸發支架386的彎折部3868、第一抵推部3866及第一磁吸部3864位於容置空間3824內，觸發支架386的按壓部3862自座體382的通孔3826伸出座體382。第一電氣端子190與第二電氣端子192自容置空間3824內伸出座體382 (例如透過埋入射出的方式實作)。第一抵推部3866位於第二抵推部3886及座體382之間。觸發支架386具有一開口3870，導通支架388穿過開口3870。In addition, in this embodiment, the base body 382 is composed of a body 3820 and a paramagnetic metal piece 3821, so that the overall structure of the base body 382 is similar to the structure of the aforementioned upper cover 1822. The fixed magnetic member 184 is disposed opposite the body 3820. Between the two side walls and the paramagnetic metal piece 3821, the fixed magnetic member 184 is exposed inside the body 3820, and other components of the switch 38 can be stably set on the base body 382. Therefore, the base body 382 need not have the lower seat as described above. The structure of 1824, but in practice it is not limited to this. For example, the base body 382 is implemented by a single component (such as a plastic injection part), and the fixed magnetic member 184 is fixed on the base body 382 (for example, by means of engagement, gluing, etc.). In addition, for example, the seat body 382 may include a structure similar to the aforementioned lower seat 1824 to enhance the protection of components and the dustproof effect. In this embodiment, the base 382 has a groove 3822, and the groove 3822 opens downward and forms a receiving space 3824. The conducting bracket 388 is disposed in the accommodating space 3824. The bending portion 3868, the first pushing portion 3866, and the first magnetic attraction portion 3864 of the triggering bracket 386 are located in the accommodating space 3824. The pressing portion 3862 of the triggering bracket 386 protrudes from the through hole 3826 of the base body 382 to the base body 382. The first electrical terminal 190 and the second electrical terminal 192 protrude from the housing 382 in the accommodating space 3824 (for example, it is implemented by being buried in and out). The first pushing portion 3866 is located between the second pushing portion 3886 and the base 382. The trigger bracket 386 has an opening 3870 through which the conducting bracket 388 passes.
於前述實施例中，開關18、38內的第一電氣端子190與第二電氣端子192間的導通是透過可導電的接觸部1882、3882同時接觸第一電氣端子190及第二電氣端子192而實現，但於實作上不以此為限。例如，將第一電氣端子190及第二電氣端子192垂直間隔設置，接觸部1882、3882相對於第二電氣端子192設置於第一電氣端子190之另一側，使得接觸部1882、3882能被驅動以接觸並抵推第一電氣端子190以使第一電氣端子190與第二電氣端子192直接相互接觸而導通；於此例中，接觸部1882、3882無需可導電。In the foregoing embodiment, the conduction between the first electrical terminal 190 and the second electrical terminal 192 in the switches 18 and 38 is achieved by simultaneously contacting the first electrical terminal 190 and the second electrical terminal 192 through the conductive contact portion 1882 and 3882. Achieved, but not limited in practice. For example, the first electrical terminal 190 and the second electrical terminal 192 are vertically spaced apart, and the contact portion 1882, 3882 is disposed on the other side of the first electrical terminal 190 relative to the second electrical terminal 192, so that the contact portions 1882, 3882 can be It is driven to contact and push the first electrical terminal 190 so that the first electrical terminal 190 and the second electrical terminal 192 are in direct contact with each other to conduct electricity; in this example, the contact portions 1882 and 3882 need not be conductive.
此外，於前述實施例中，在開關18、38未被觸發前，第二電氣端子192與接觸部1882、3882是分開的，但於實作上亦可使第二電氣端子192與接觸部1882、3882於開關18、38未被觸發前即已電連接，而於接觸部1882、3882接觸第一電氣端子190時，第二電氣端子192即能經由接觸部1882、3882與第一電氣端子190電連接以實現第一電氣端子190與第二電氣端子192間的導通。請參閱圖12至圖16。根據另一實施例之一按鍵結構4，其與按鍵結構1結構相似，故沿用按鍵結構1之元件符號。按鍵結構4與按鍵結構1的主要差異在於按鍵結構4的開關48的導通支架488以不同的方式導通第一電氣端子190與第二電氣端子492，以實現開關48的觸發。但於開關48中，觸發支架186與導通支架488間相互抵推的作動實質上與開關18中觸發支架186與導通支架188間相互抵推的作動相同。因此，關於按鍵結構4各構件之其他說明，請參閱前文中按鍵結構1中命名相同的元件之相關說明及其變化說明，不另贅述。In addition, in the foregoing embodiment, before the switches 18 and 38 are not triggered, the second electrical terminal 192 is separated from the contact portion 1882, 3882, but the second electrical terminal 192 and the contact portion 1882 can also be implemented in practice. , 3882 are electrically connected before the switches 18 and 38 are not triggered. When the contact portion 1882, 3882 contacts the first electrical terminal 190, the second electrical terminal 192 can be connected to the first electrical terminal 190 through the contact portion 1882, 3882. It is electrically connected to achieve conduction between the first electrical terminal 190 and the second electrical terminal 192. See Figures 12 to 16. According to another embodiment of the key structure 4, the structure of the key structure 4 is similar to the structure of the key structure 1, so the component symbols of the key structure 1 are used. The main difference between the key structure 4 and the key structure 1 is that the conducting bracket 488 of the switch 48 of the key structure 4 conducts the first electrical terminal 190 and the second electrical terminal 492 in different ways to realize the triggering of the switch 48. However, in the switch 48, the action of pushing the trigger bracket 186 and the conducting bracket 488 against each other is substantially the same as the action of pushing the trigger bracket 186 and the conduction bracket 188 against each other in the switch 18. Therefore, for other descriptions of the components of the key structure 4, please refer to the related description of the same-named components in the key structure 1 and the description of the changes thereof, and will not repeat them.
於本實施例中，導通支架488的接觸部4882僅與第一電氣端子190相對設置，第二電氣端子492則固定連接至導通支架488相對於接觸部4882之另一側且與接觸部4882經由導通支架488電連接。其中，導通支架488可經適當設計結構上具有一定程度變形彈性特性的懸臂結構4883，提供導通支架488具有使接觸部4882旋向固定磁吸件184之懸臂彈力；當按壓部1862未被按壓時(例如未被鍵帽12按壓)，第一磁吸力F1對觸發支架186產生之力矩大於導通支架488的懸臂結構4883彈力，故如圖15所示，第一磁吸力F1驅使觸發支架186旋向固定磁吸件184，使得觸發支架186經由第一抵推部1866抵推第二抵推部4886，懸臂結構4883產生較大彈性變形(為簡化圖面，仍以直線繪示於圖中)，接觸部4882旋離固定磁吸件184使得接觸部4882遠離第一電氣端子190；換言之，第一電氣端子190與第二電氣端子192未導通(或謂未電性連接)，亦即開關48未被觸發。藉此，當觸發支架186的按壓部1862被按壓時，第一磁吸部1864與固定磁吸件184之間產生的第一磁吸力F1被按壓按壓部1862之外力克服，觸發支架186旋離固定磁吸件184，導通支架488之懸臂結構4883懸臂彈力驅使第一抵推部1866持續抵接導通支架488之第二抵推部4886，懸臂結構4883彈性變形量減少，接觸部4882旋向固定磁吸件184。In this embodiment, the contact portion 4882 of the conducting bracket 488 is only opposite to the first electrical terminal 190, and the second electrical terminal 492 is fixedly connected to the other side of the conducting bracket 488 opposite to the contact portion 4882 and through the contact portion 4882. The conducting bracket 488 is electrically connected. Among them, the conducting bracket 488 can be appropriately designed with a cantilever structure 4883 that has a certain degree of deformation and elastic characteristics, and the conducting bracket 488 has a cantilever elastic force that enables the contact portion 4882 to rotate toward the fixed magnetic member 184; when the pressing portion 1862 is not pressed, (For example, not pressed by the keycap 12), the first magnetic attraction force F1 generates a larger moment on the trigger bracket 186 than the cantilever structure 4883 of the conducting bracket 488. Therefore, as shown in FIG. 15, the first magnetic attraction force F1 drives the trigger bracket 186 to rotate. Fix the magnetic member 184 so that the trigger bracket 186 pushes against the second pushing portion 4886 via the first pushing portion 1866, and the cantilever structure 4883 generates a large elastic deformation (to simplify the figure, it is still shown in a straight line in the figure). The contact portion 4882 is rotated away from the fixed magnetic member 184 so that the contact portion 4882 is far from the first electrical terminal 190. In other words, the first electrical terminal 190 and the second electrical terminal 192 are not conductive (or are not electrically connected), that is, the switch 48 is not Was triggered. Thereby, when the pressing portion 1862 of the trigger bracket 186 is pressed, the first magnetic attraction force F1 generated between the first magnetic attraction portion 1864 and the fixed magnetic member 184 is overcome by the force outside the pressing and pressing portion 1862, and the trigger bracket 186 is rotated away The magnetic member 184 is fixed, the cantilever structure 4883 of the conducting bracket 488 cantilever elastic force drives the first pushing portion 1866 to continuously abut the second pushing portion 4886 of the conducting bracket 488, the elastic deformation of the cantilever structure 4883 is reduced, and the contact portion 4882 is rotated to be fixed磁 件 件 184。 Magnetic member 184.
當按壓部1862被按壓至該設定位置時，導通支架488經由接觸部4882接觸第一電氣端子190以導通第一電氣端子190與第二電氣端子492，導通支架488之懸臂結構4883維持適度變形彈力提供接觸部4882與第一電氣端子190接觸抵接力，第一抵推部1866與第二抵推部4886開始分離，如圖16所示。當按壓部1862持續向下按壓時，第一抵推部1866與第二抵推部4886完全分離，導通支架488之懸臂結構4883持續維持設定之懸臂變形彈力持續驅使接觸部4882保持接觸第一電氣端子190，此時接觸部4882接觸第一電氣端子190之接觸力係決定於懸臂結構4883之懸臂變形彈力，與按壓部1862的按壓力無關。When the pressing portion 1862 is pressed to the set position, the conductive bracket 488 contacts the first electrical terminal 190 via the contact portion 4882 to conduct the first electrical terminal 190 and the second electrical terminal 492. The cantilever structure 4883 of the conductive bracket 488 maintains a moderate deformation elastic force. A contact force is provided for the contact portion 4882 to contact the first electrical terminal 190, and the first pushing portion 1866 and the second pushing portion 4886 begin to separate, as shown in FIG. 16. When the pressing portion 1862 is continuously pressed down, the first pushing portion 1866 is completely separated from the second pushing portion 4886, and the cantilever structure 4883 of the conducting bracket 488 continues to maintain the set cantilever deformation elastic force to continuously drive the contact portion 4882 to keep contact with the first electrical For the terminal 190, the contact force of the contact portion 4882 with the first electrical terminal 190 is determined by the cantilever deformation elastic force of the cantilever structure 4883, and has nothing to do with the pressing force of the pressing portion 1862.
於本實施例中，接觸部4882與第一電氣端子190之接觸力藉懸臂結構4883之懸臂變形彈力外，亦可進一步地選擇於導通支架488上對應固定磁吸件184設有輔助磁吸片194，藉兩者間磁吸力F2輔助接觸部4882與第一電氣端子190之導通接觸力需求。In this embodiment, in addition to the contact force of the contact portion 4882 and the first electrical terminal 190 by the cantilever deformation elastic force of the cantilever structure 4883, an auxiliary magnetic piece can be further provided on the conducting bracket 488 corresponding to the fixed magnetic piece 184. 194. The magnetic contact force F2 between the two is used to assist the conducting contact force requirement of the contact portion 4882 and the first electrical terminal 190.
此外，於本實施例中，導通支架488與第二電氣端子492一體成型(例如由一順磁性金屬板件，經衝壓成型)，但於實作上不以此為限，例如導通支架488與第二電氣端子492為兩個構件，經焊接或卡合結構而固定連接在一起。又，於實作上，導通支架488與第二電氣端子492亦得以接觸的方式(例如導通支架488之一端部抵靠於第二電氣端子492上)，實現於開關48未被觸發前導通支架488與第二電氣端子492即已電連接之效果。此外，於本實施例中，開關48的座體482的上蓋4822及下座4824銜接形成一容置空間4826，用以容置開關48其他構件。上蓋4822與下座4824同時夾持導通支架488與第二電氣端子492一體成型的結構，使之如懸臂結構般的作動。在第二磁吸力F2的作用下(例如第二磁吸力F2足使導通支架488偏轉)，導通支架488能大致以相對於接觸部4882之一側為固定端而可相對於座體482朝向固定磁吸件184偏轉。此偏轉效果與前文中導通支架188、388在第二磁吸力F2的作用下而相對於座體182、382旋轉之效果相當，均能使導通支架188、388相對於座體182、382之結構方向(或謂方位)改變，故於開關18、38中，導通支架188、388亦可採懸臂結構實作；同理，於開關18、38中，觸發支架186亦可採懸臂結構實作。另外，於本文中，旋轉或偏轉均意指使構件的結構方向(或謂方位)改變，故於理解本文所述之實施例時，觸發支架186、386及導通支架188、388、488的旋向或旋離作動均視實際結構配置而包含旋轉或偏轉的情形，不另外再用不同的字詞來區隔描述。 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。In addition, in this embodiment, the conducting bracket 488 is integrally formed with the second electrical terminal 492 (for example, a paramagnetic metal plate is formed by stamping), but it is not limited in practice. For example, the conducting bracket 488 and The second electrical terminal 492 is two components, and is fixedly connected together through a welding or engaging structure. In addition, in practice, the conducting bracket 488 and the second electrical terminal 492 can also be contacted (for example, one end of the conducting bracket 488 abuts against the second electrical terminal 492), so that the conducting bracket is turned on before the switch 48 is triggered. The effect that 488 is electrically connected to the second electrical terminal 492. In addition, in this embodiment, the upper cover 4822 and the lower seat 4824 of the base 482 of the switch 48 are connected to form an accommodation space 4826 for receiving other components of the switch 48. The upper cover 4822 and the lower seat 4824 simultaneously hold a structure in which the conducting bracket 488 and the second electrical terminal 492 are integrally formed, so as to act like a cantilever structure. Under the action of the second magnetic attraction force F2 (for example, the second magnetic attraction force F2 deflects the conducting bracket 488), the conducting bracket 488 can be fixed with respect to one side of the contact portion 4882 as a fixed end and can be fixed relative to the base 482. The magnetic member 184 is deflected. This deflection effect is equivalent to that of the conducting brackets 188 and 388 rotating relative to the bases 182 and 382 under the effect of the second magnetic attraction force F2 in the foregoing. Both can make the conducting brackets 188 and 388 relative to the structures of the bases 182 and 382. The direction (or orientation) is changed. Therefore, in the switches 18 and 38, the conducting bracket 188 and 388 can also be implemented by a cantilever structure. Similarly, in the switches 18 and 38, the trigger bracket 186 can also be implemented by a cantilever structure. In addition, in this article, rotation or deflection means to change the structural direction (or orientation) of the component. Therefore, when understanding the embodiments described herein, the rotation directions of the brackets 186, 386 and the conducting brackets 188, 388, 488 are triggered. Or the spin-off action includes rotation or deflection depending on the actual structural configuration, and different words are not used to separate the description. The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made in accordance with the scope of patent application of the present invention shall fall within the scope of the present invention.
