Description
本發明關於一種按鍵結構，尤指一種機械式按鍵結構。 The invention relates to a button structure, in particular to a mechanical button structure.
為便於攜帶，目前可攜式電子裝置均朝向超薄型外觀設計。於薄型鍵盤中，其具有較薄的按鍵結構，此雖可便於收納，但因其鍵帽不具有足夠的上下移動距離，使得使用者按壓按鍵時，手感不足，十分不便。而於傳統鍵盤中，其鍵帽雖具有較大的上下移動距離，可提供使用者足夠的按壓手感，但鍵盤整體厚度則太大而不利於收納。因此，目前的鍵盤設計面臨縮小體積以利於收納和高按壓行程之兩難。 For portability, portable electronic devices are now designed to be ultra-thin. In the thin keyboard, the thin keyboard structure has a thin button structure, which is convenient for storage. However, since the key cap does not have a sufficient moving distance, the user feels inconvenient when pressing the button, which is very inconvenient. In the conventional keyboard, although the key cap has a large moving distance, it can provide sufficient pressing feeling for the user, but the overall thickness of the keyboard is too large to facilitate storage. Therefore, the current keyboard design faces the dilemma of reducing the size to facilitate storage and high press stroke.
鑑於先前技術中的問題，本發明的目的之一在於提供一種按鍵結構，其具有利用磁力之鍵帽回彈機構，利用改變磁力量值或經由構件移動強制其升降機構靠近底座以使鍵帽能保持在相對較低的位置，以便於收納。 In view of the problems in the prior art, one of the objects of the present invention is to provide a button structure having a keycap rebound mechanism utilizing a magnetic force, forcing a keycap by changing a magnetic force value or forcing a lifting mechanism thereof to move closer to the base via a member movement Keep it in a relatively low position for easy storage.
根據本發明之一實施例，該按鍵結構包含一底座、一鍵帽、一升降機構、一驅動件及一滑動板。該底座包含一第一磁性部。該升降機構設置於該底座與該鍵帽之間，使得該鍵帽經由該升降機構而能平行於一第一方向相對於該底座移動。該驅動件設置於該底座與該鍵帽之間並抵接該底座，該驅動件包含一第二磁性部，位於該第一磁性部之上，該第二磁性部與該第一磁性部間產生一磁力，該磁力可驅使該驅動件相對於該底座旋轉使得該鍵帽經由該升降機構遠離該底座移動。該滑動板可滑動地設置於該升降機構與該底座之間，該滑動板連接該升降機構，當該滑動板以一第二方向移動時，驅動該升降機構靠近該底座。藉此，該鍵帽可保持在相對較低的位置，以便於 收納。進一步地，該滑動板可包含一遮蔽件，當該滑動板以該第一方向移動以驅動該升降機構靠近該底座時，該遮蔽件亦同時滑至該第一磁性部與該第二磁性部之間。此時，該遮蔽件受到該第一磁性部形成之磁場而暫時性地磁化，使得該第二磁性部感受到的磁場強度減弱，亦即該第二磁性部與該第一磁性部間產生的磁力亦減弱，有助於該鍵帽下降而保持在相對較低的位置。 According to an embodiment of the invention, the button structure comprises a base, a keycap, a lifting mechanism, a driving member and a sliding plate. The base includes a first magnetic portion. The lifting mechanism is disposed between the base and the keycap such that the keycap can move relative to the base parallel to a first direction via the lifting mechanism. The driving member is disposed between the base and the keycap and abuts the base, the driving component comprises a second magnetic portion located on the first magnetic portion, and between the second magnetic portion and the first magnetic portion A magnetic force is generated that drives the drive member to rotate relative to the base such that the keycap moves away from the base via the lift mechanism. The sliding plate is slidably disposed between the lifting mechanism and the base, and the sliding plate is coupled to the lifting mechanism to drive the lifting mechanism to be adjacent to the base when the sliding plate moves in a second direction. Thereby, the keycap can be kept in a relatively low position, so as to facilitate Storage. Further, the sliding plate may include a shielding member, and when the sliding plate moves in the first direction to drive the lifting mechanism to approach the base, the shielding member also slides to the first magnetic portion and the second magnetic portion simultaneously between. At this time, the shielding member is temporarily magnetized by the magnetic field formed by the first magnetic portion, so that the strength of the magnetic field sensed by the second magnetic portion is weakened, that is, between the second magnetic portion and the first magnetic portion. The magnetic force is also weakened, helping the keycap to fall while remaining in a relatively low position.
根據本發明之另一實施例，該按鍵結構包含一底座、一鍵帽、一升降機構、一驅動件及一遮蔽件。該底座包含一第一磁性部。該升降機構設置於該底座與該鍵帽之間，使得該鍵帽經由該升降機構而能平行於一方向相對於該底座移動。該驅動件設置於該底座與該鍵帽之間並抵接該底座，該驅動件包含一第二磁性部，位於該第一磁性部之上，該第二磁性部與該第一磁性部間產生一磁力，該磁力可驅使該驅動件相對於該底座旋轉使得該鍵帽經由該升降機構遠離該底座移動。該遮蔽件可滑動地設置於該升降機構與該底座之間，該遮蔽件能被該第一磁性部暫時性地磁化。其中，當該遮蔽件滑至該第一磁性部與該第二磁性部之間時，該遮蔽件受到該第一磁性部形成之磁場而暫時性地磁化，使得該第二磁性部感受到的磁場強度減弱，亦即該第二磁性部與該第一磁性部間產生的磁力亦減弱，致無法有效驅使該升降機構驅動該鍵帽遠離該底座移動，有助於該鍵帽下降，故此時該鍵帽可保持在相對較低的位置，以便於收納。 According to another embodiment of the present invention, the button structure comprises a base, a keycap, a lifting mechanism, a driving member and a shielding member. The base includes a first magnetic portion. The lifting mechanism is disposed between the base and the key cap such that the key cap can move relative to the base in parallel with a direction via the lifting mechanism. The driving member is disposed between the base and the keycap and abuts the base, the driving component comprises a second magnetic portion located on the first magnetic portion, and between the second magnetic portion and the first magnetic portion A magnetic force is generated that drives the drive member to rotate relative to the base such that the keycap moves away from the base via the lift mechanism. The shielding member is slidably disposed between the lifting mechanism and the base, and the shielding member can be temporarily magnetized by the first magnetic portion. Wherein, when the shielding member slides between the first magnetic portion and the second magnetic portion, the shielding member is temporarily magnetized by the magnetic field formed by the first magnetic portion, so that the second magnetic portion senses The strength of the magnetic field is weakened, that is, the magnetic force generated between the second magnetic portion and the first magnetic portion is also weakened, so that the lifting mechanism can not effectively drive the lifting mechanism to move away from the base, which helps the keycap to descend. The keycap can be held in a relatively low position for easy storage.
相較於先前技術，本發明之按鍵結構具有兩種狀態：一是使用狀態，另一是收納狀態。於使用狀態下，該鍵帽可受到該磁力的作用而處於相對較高的位置，進而提供使用者足夠的按壓行程(可藉由該升降機構之作動設計而實現)，可滿足使用者對按壓手感的需求。於收納狀態下，滑動板讓升降機構下降，再加上該遮蔽件讓該第二磁性部與該第一磁性部間產生的磁力減弱，幫助按鍵結構成為收納狀態。 Compared to the prior art, the button structure of the present invention has two states: one is a use state and the other is a stowed state. In the state of use, the key cap can be in a relatively high position by the action of the magnetic force, thereby providing the user with a sufficient pressing stroke (which can be realized by the actuation design of the lifting mechanism), which can satisfy the user's pressing. Feel the need. In the stored state, the sliding plate lowers the lifting mechanism, and the shielding member weakens the magnetic force generated between the second magnetic portion and the first magnetic portion, thereby helping the button structure to be in a stored state.

請參閱第1至第4圖。第1圖為根據本發明之一實施例之一按鍵結構1之示意圖，第2圖為按鍵結構1之***圖，第3圖為按鍵結構1沿第1圖中線X-X之剖面圖，第4圖為第3圖中按鍵結構1於另一狀態之剖面圖。按鍵結構1包含一底座10、一鍵帽12、一升降機構14、一驅動件15、一滑動板16及一遮蔽件18。鍵帽12設置於底座10之上，升降機構14設置於底座10與鍵帽12之間，使得鍵帽12經由升降機構14而能沿一第一方向D1(例如垂直方向)相對於底座10移動；於本實施例中，即鍵帽12相對於底座10垂直上下移動。驅動件15設置於底座10與鍵帽12之間並抵接底座10，滑動板16可滑動地設置於底座10及鍵帽12之間。遮蔽件18可滑動地設置於升降機構14與底座10之間；於本實施例中，遮蔽件18位於滑動板16，故可一起移動，例如透過滑動板16來移動遮蔽件18。此外，於本實施例中，遮蔽件18與滑動板16一體成形，但本發明不以此為限。 Please refer to Figures 1 to 4. 1 is a schematic view of a button structure 1 according to an embodiment of the present invention, FIG. 2 is an exploded view of the button structure 1, and FIG. 3 is a cross-sectional view of the button structure 1 along line XX in FIG. The figure is a cross-sectional view of the button structure 1 in Fig. 3 in another state. The button structure 1 includes a base 10, a keycap 12, a lifting mechanism 14, a driving member 15, a sliding plate 16, and a shielding member 18. The key cap 12 is disposed on the base 10, and the lifting mechanism 14 is disposed between the base 10 and the keycap 12, so that the keycap 12 can move relative to the base 10 in a first direction D1 (for example, a vertical direction) via the lifting mechanism 14. In the present embodiment, the keycap 12 is vertically moved up and down with respect to the base 10. The driving member 15 is disposed between the base 10 and the keycap 12 and abuts against the base 10. The sliding plate 16 is slidably disposed between the base 10 and the keycap 12. The shielding member 18 is slidably disposed between the lifting mechanism 14 and the base 10; in the present embodiment, the shielding member 18 is located on the sliding plate 16, so that the shielding member 18 can be moved together, for example, through the sliding plate 16. In addition, in the present embodiment, the shielding member 18 is integrally formed with the sliding plate 16, but the invention is not limited thereto.
進一步來說，底座10包含一底板102、一薄膜電路板104及一第一磁性部106，薄膜電路板104設置於底板102並包含電路開關，以供觸發按鍵輸入功能。第一磁性部106設置於底板102上，於實作上可為但不限於一磁鐵。升降機構14包含一第一支架142及一第二支架144。第一支架142與第二支架144樞接，兩者之間產生連動，使得鍵帽12經由第一支架142與第二支架144而能大致平穩地平行於第一方向D1相對於底座10上下移動；其中，第一支架142連接滑動板16之連接部162及鍵帽12之間，第二支架144連接底座10之底板102之連接部1022及鍵帽12之間。但本發明不以此 為限，例如第一支架與第二支架分隔設置，另以連桿保持兩者作動平衡且相互關聯。 Further, the base 10 includes a bottom plate 102, a thin film circuit board 104 and a first magnetic portion 106. The thin film circuit board 104 is disposed on the bottom plate 102 and includes circuit switches for triggering the key input function. The first magnetic portion 106 is disposed on the bottom plate 102, and may be, but is not limited to, a magnet. The lifting mechanism 14 includes a first bracket 142 and a second bracket 144. The first bracket 142 is pivotally connected to the second bracket 144, and the interlocking between the two supports 144 causes the keycap 12 to move up and down relative to the base 10 substantially parallel to the first direction D1 via the first bracket 142 and the second bracket 144. The first bracket 142 is connected between the connecting portion 162 of the sliding plate 16 and the keycap 12, and the second bracket 144 is connected between the connecting portion 1022 of the bottom plate 102 of the base 10 and the keycap 12. But the invention does not use this For example, the first bracket is spaced apart from the second bracket, and the connecting rod is used to maintain the balance of the two and are associated with each other.
驅動件15包含一第二磁性部152，對應第一磁性部106於本實施例中，驅動件15呈一V形結構件(其具有一V形輪廓截面，如第3圖所示者)，驅動件15具有一頂點邊15a(即V形輪廓截面之頂點沿V形結構件垂直於V形輪廓截面之延伸方向延伸形成之稜邊)及位於頂點邊15a兩側之一第一部位15b及一第二部位15c。驅動件15以頂點邊15a抵接底座10之底板102，驅動件15以第二部位15c驅動鍵帽12，使得驅動件15相對於底座10以頂點邊15a為支點，而呈現翹翹板的作動。第二磁性部152位於第一部位15b且位於第一磁性部106之上，第二磁性部152與第一磁性部106間能產生一磁力F(以箭頭表示於第3圖及第4圖中)以驅使升降機構14驅動鍵帽12遠離底座10移動；換言之，磁力F可驅使驅動件15相對於底座10旋轉使得鍵帽12經由升降機構14遠離底座10移動。進一步而言，驅動件15以第二部位15c抵接第一支架142，磁力F可驅使驅動件15相對於底座10旋轉(以第3圖之視角而言，為順時針旋轉)，驅動件15以第二部位15c連動第一支架142及第二支架144，使得鍵帽12上升；換言之，磁力F透過驅動件15以驅使第一支架142及第二支架144驅動鍵帽12遠離底座10移動。於實作上，第二磁性部152由順磁性材料或其他能暫時性地磁化之材料或結構(包含複合材料)製成，第二磁性部152受到第一磁性部106建立的磁場作用而於第二磁性部152與第一磁性部106之間產生磁力F(即磁吸力)，驅使第二磁性部152靠近第一磁性部106，進而產生前述驅動件15順時針的旋轉。於本實施例中，驅動件15與第二磁性部152一體成形，且係一鐵合金件；但本發明不以此為限。 The driving member 15 includes a second magnetic portion 152 corresponding to the first magnetic portion 106. In the embodiment, the driving member 15 has a V-shaped structural member (having a V-shaped profile, as shown in FIG. 3). The driving member 15 has a vertex edge 15a (ie, an edge of the V-shaped profile section extending along a direction in which the V-shaped structural member extends perpendicularly to the extending direction of the V-shaped profile section) and a first portion 15b located on either side of the vertex side 15a and A second portion 15c. The driving member 15 abuts the bottom plate 102 of the base 10 with the vertex side 15a, and the driving member 15 drives the keycap 12 with the second portion 15c, so that the driving member 15 is supported by the vertex side 15a with respect to the base 10, and the movement of the seesaw is presented. . The second magnetic portion 152 is located on the first portion 15b and located above the first magnetic portion 106. A magnetic force F can be generated between the second magnetic portion 152 and the first magnetic portion 106 (indicated by arrows in FIGS. 3 and 4). In order to drive the lifting mechanism 14 to drive the keycap 12 to move away from the base 10; in other words, the magnetic force F can drive the driving member 15 to rotate relative to the base 10 such that the keycap 12 moves away from the base 10 via the lifting mechanism 14. Further, the driving member 15 abuts the first bracket 142 with the second portion 15c, and the magnetic force F can drive the driving member 15 to rotate relative to the base 10 (clockwise rotation in the perspective of FIG. 3), the driving member 15 The first bracket 142 and the second bracket 144 are linked by the second portion 15c to cause the keycap 12 to rise; in other words, the magnetic force F is transmitted through the driving member 15 to drive the first bracket 142 and the second bracket 144 to drive the keycap 12 to move away from the base 10. In practice, the second magnetic portion 152 is made of a paramagnetic material or other material or structure (including a composite material) that can be temporarily magnetized, and the second magnetic portion 152 is subjected to a magnetic field established by the first magnetic portion 106. A magnetic force F (ie, a magnetic attraction force) is generated between the second magnetic portion 152 and the first magnetic portion 106 to drive the second magnetic portion 152 closer to the first magnetic portion 106, thereby generating a clockwise rotation of the driving member 15. In the embodiment, the driving member 15 and the second magnetic portion 152 are integrally formed and are an iron alloy member; however, the invention is not limited thereto.
補充說明的是，於本實施例中，第一支架142及第二支架144主要作為鍵帽12上下移動的結構支撐，驅動件15配合第二磁性部152與第一磁性部106之相互作用而產生鍵帽12之復位機制，直接經由第一支架142使鍵帽12向上移動，但本發明不以此為限。例如，驅動件15直接經由第二支 架144(例如第二部位15c抵接第二支架144)使鍵帽12向上移動。又例如，驅動件15以第二部位15c直接抵接鍵帽12(例如其底表面)，使得磁力F直接經由驅動件15對鍵帽12施力，使其向上移動；此時，升降機構14仍負擔鍵帽12相對於底座10上下移動的穩定性。 It is to be noted that, in this embodiment, the first bracket 142 and the second bracket 144 are mainly supported as a structure in which the key cap 12 moves up and down, and the driving member 15 cooperates with the second magnetic portion 152 to interact with the first magnetic portion 106. The reset mechanism of the keycap 12 is generated to directly move the keycap 12 upward through the first bracket 142, but the invention is not limited thereto. For example, the drive member 15 is directly via the second branch The frame 144 (eg, the second portion 15c abuts the second bracket 144) moves the keycap 12 upward. For another example, the driving member 15 directly abuts the keycap 12 (for example, the bottom surface thereof) by the second portion 15c, so that the magnetic force F directly urges the keycap 12 via the driving member 15 to move upward; at this time, the lifting mechanism 14 The stability of the keycap 12 moving up and down relative to the base 10 is still incurred.
於本實施例中，遮蔽件18與滑動板16一體成形且以順磁性材料(例如鐵合金)或其他能暫時性地磁化之材料或結構(包含複合材料)製成。當滑動板16以一第二方向D2(例如水平方向)相對於底座10滑動，使得遮蔽件18滑至第一磁性部106與第二磁性部152之間時，遮蔽件18被第一磁性部106暫時性地磁化，使得第一磁性部106建立的磁場產生變化，第二磁性部152感受到的磁場強度變弱，亦即此時第二磁性部152與第一磁性部106之間產生之磁力F減弱而有助於鍵帽12下降。當滑動板16以相反於第二方向D2之方向相對於底座10滑動時，遮蔽件18即可滑出第一磁性部106與第二磁性部152之間。其中，第一方向D1與第二方向D2相互垂直。另外，於本實施例中，因滑動板16亦經由連接部162以與第一支架142連接，故滑動板16以第二方向移動遮蔽件18至第一磁性部106與第二磁性部152之間時，滑動板16亦同時驅動第一支架142靠向底座10旋轉(以第4圖之視角而言，即相對於底座10逆時針旋轉)，使得鍵帽12被第一支架142連動而往下移動，使得鍵帽12朝向底座10移動且第一磁性部106與第二磁性部152間之距離增加；同時，由於第一支架142與第二支架144樞接，第一支架142靠向底座10旋轉亦連動第二支架144靠向底座10旋轉。換言之，於滑動板16以第二方向D2移動以驅動升降機構14靠近底座10後，遮蔽件18即位於第一磁性部106與第二磁性部152之間。因此，於本實施例中，滑動板16能讓升降機構14下降，再加上遮蔽件18讓磁力F減弱，均幫助按鍵結構1成為收納狀態，以便於收納。 In the present embodiment, the shield 18 is integrally formed with the sliding plate 16 and is made of a paramagnetic material (such as a ferroalloy) or other material or structure (including a composite material) that can be temporarily magnetized. When the sliding plate 16 slides relative to the base 10 in a second direction D2 (for example, a horizontal direction) such that the shielding member 18 slides between the first magnetic portion 106 and the second magnetic portion 152, the shielding member 18 is replaced by the first magnetic portion. The magnetic field is temporarily magnetized such that the magnetic field established by the first magnetic portion 106 changes, and the intensity of the magnetic field sensed by the second magnetic portion 152 becomes weak, that is, between the second magnetic portion 152 and the first magnetic portion 106. The magnetic force F is weakened to help the keycap 12 to descend. When the slide plate 16 slides relative to the base 10 in a direction opposite to the second direction D2, the shield 18 can slide out between the first magnetic portion 106 and the second magnetic portion 152. The first direction D1 and the second direction D2 are perpendicular to each other. In addition, in the embodiment, since the sliding plate 16 is also connected to the first bracket 142 via the connecting portion 162, the sliding plate 16 moves the shielding member 18 to the first magnetic portion 106 and the second magnetic portion 152 in the second direction. During the interval, the sliding plate 16 also drives the first bracket 142 to rotate toward the base 10 (in the perspective of FIG. 4, that is, counterclockwise rotation with respect to the base 10), so that the keycap 12 is linked by the first bracket 142. Moving downwards causes the keycap 12 to move toward the base 10 and the distance between the first magnetic portion 106 and the second magnetic portion 152 increases; meanwhile, since the first bracket 142 is pivotally connected to the second bracket 144, the first bracket 142 is abutted toward the base The 10 rotation also interlocks the second bracket 144 against the base 10. In other words, after the sliding plate 16 is moved in the second direction D2 to drive the lifting mechanism 14 close to the base 10, the shielding member 18 is located between the first magnetic portion 106 and the second magnetic portion 152. Therefore, in the present embodiment, the slide plate 16 can lower the lift mechanism 14, and the shield member 18 can weaken the magnetic force F, thereby helping the button structure 1 to be in a stowed state for storage.
請參閱第5圖，其為根據另一實施例之按鍵結構3之***圖；按鍵結構3之剖面圖可直接參閱按鍵結構1有關的剖面圖(如第3圖及第4圖)。 按鍵結構3與按鍵結構1結構大致相同，故按鍵結構3仍沿用按鍵結構1之元件符號，關於按鍵結構3之其他說明，請參閱按鍵結構1之相關說明(及其對應的圖式)，不另贅述。按鍵結構3與按鍵結構1主要不同之處在於按鍵結構3之升降機構14不再與滑動板36連接，而是直接與底座30連接，亦即於按鍵結構3中，升降機構14之第一支架142及第二支架144個別地連接底座30之底板302之連接部1022(或連接部1024)及鍵帽12，鍵帽12同樣是經由第一支架142及第二支架144而能沿第一方向D1相對於底座10上下移動。於本實施例中，滑動板36不再與第一支架142及第二支架144結構連接，故僅負責遮蔽件18的滑動。同樣的，當滑動板36以第二方向D2相對於底座30滑動，使得遮蔽件18滑至第一磁性部106與第二磁性部152之間時(可參閱第4圖)，遮蔽件18被第一磁性部106暫時性地磁化，使得第一磁性部106建立的磁場產生變化，第二磁性部152感受到的磁場強度變弱，亦即此時第二磁性部152與第一磁性部106之間產生之磁力F減弱而無法有效克服鍵帽12、升降機構14自身重量以驅使升降機構14驅動鍵帽12遠離底座30移動。此時，鍵帽12受到自身重量(或重力)或外力而向下(即朝向底座30)移動，同樣可降低鍵帽12高度(有利於收納)。 Please refer to FIG. 5, which is an exploded view of the button structure 3 according to another embodiment; the cross-sectional view of the button structure 3 can directly refer to the cross-sectional view of the button structure 1 (such as FIG. 3 and FIG. 4). The button structure 3 and the button structure 1 have substantially the same structure, so the button structure 3 still uses the component symbol of the button structure 1. For other descriptions of the button structure 3, please refer to the description of the button structure 1 (and its corresponding schema), Let me repeat. The button structure 3 is mainly different from the button structure 1 in that the lifting mechanism 14 of the button structure 3 is no longer connected to the sliding plate 36, but is directly connected to the base 30, that is, in the button structure 3, the first bracket of the lifting mechanism 14 142 and the second bracket 144 are respectively connected to the connecting portion 1022 (or the connecting portion 1024) of the bottom plate 302 of the base 30 and the key cap 12, and the key cap 12 is also in the first direction via the first bracket 142 and the second bracket 144. D1 moves up and down with respect to the base 10. In the present embodiment, the sliding plate 36 is no longer connected to the first bracket 142 and the second bracket 144, so it is only responsible for the sliding of the shielding member 18. Similarly, when the slide plate 36 slides relative to the base 30 in the second direction D2 such that the shield 18 slides between the first magnetic portion 106 and the second magnetic portion 152 (see FIG. 4), the shield 18 is The first magnetic portion 106 is temporarily magnetized such that the magnetic field established by the first magnetic portion 106 changes, and the strength of the magnetic field sensed by the second magnetic portion 152 becomes weak, that is, the second magnetic portion 152 and the first magnetic portion 106 at this time. The magnetic force F generated between them is weakened and the weight of the keycap 12 and the lifting mechanism 14 itself cannot be effectively overcome to drive the lifting mechanism 14 to drive the keycap 12 to move away from the base 30. At this time, the keycap 12 is moved downward (ie, toward the base 30) by its own weight (or gravity) or external force, and the height of the keycap 12 can also be lowered (favorable for storage).
