鍵盤作為個人桌上型電腦與筆記型電腦的實體輸入介面，使用者對其規格與操作手感等要求日益趨高。舉例來說，一般的薄膜式鍵盤所採用的橡膠圓頂（Rubber Dome）通常在受力按壓時瞬間潰縮，此時產生的聲響不受部分消費者青睞，並且按鍵結構瞬間潰縮產生的段落手感，在某些應用中亦造成使用者的困擾。例如，在進行射擊遊戲時，使用者射擊的速度會因為按鍵結構的段落手感，造成射擊的速度降低，而影響遊戲體驗。因此，如何提供一種無段落感之按壓手感的按鍵結構，已成為目前亟待解決與克服的問題之一。The keyboard is used as a physical input interface for personal desktop computers and notebook computers, and users have increasingly higher requirements on specifications and operating feel. For example, the rubber dome used in general membrane keyboards usually collapses when pressed, and the sound produced at this time is not favored by some consumers, and the paragraphs caused by the instantaneous collapse of the key structure Feel, in some applications also cause user distress. For example, in a shooting game, the shooting speed of the user will be reduced due to the paragraph feel of the key structure, which will affect the game experience. Therefore, how to provide a key structure without pressing a feeling of paragraph has become one of the problems urgently to be solved and overcome at present.

本發明提供一種可拆卸式按鍵結構與電子裝置，其能夠避免按壓鍵帽的過程中所產生的聲響，具有無段落感的按壓手感。The invention provides a detachable key structure and an electronic device, which can avoid the sound generated in the process of pressing the key cap, and has a feeling of pressing without a sense of paragraph.

本發明的可拆卸式按鍵結構，適於與一薄膜電路板接觸。可拆卸式按鍵結構包括一鍵帽以及一彈性觸發件。鍵帽包括彼此分離的多個限位部。這些限位部定義出一容置區，且各個限位部具有一上表面。彈性觸發件配置於容置區中，且包括一觸發部以及圍繞觸發部的一環狀部。觸發部的長度小於環狀部的長度。環狀部具有彼此相對的一頂面與一底面。環狀部的頂面承靠並固定於各個限位部的上表面上，而環狀部的底面直接接觸薄膜電路板。在按壓鍵帽以使彈性觸發件的觸發部接觸薄膜電路板的過程中，彈性觸發件的環狀部產生彈性變形，使觸發部不會因瞬間潰縮而產生聲響。The detachable key structure of the present invention is suitable for contact with a thin film circuit board. The detachable key structure includes a key cap and an elastic trigger. The keycap includes a plurality of limit parts separated from each other. The limiting portions define an accommodating area, and each limiting portion has an upper surface. The elastic trigger is disposed in the accommodating area, and includes a trigger portion and a ring portion surrounding the trigger portion. The length of the trigger part is smaller than the length of the ring part. The ring portion has a top surface and a bottom surface opposed to each other. The top surface of the ring portion bears and is fixed on the upper surface of each limit portion, and the bottom surface of the ring portion directly contacts the thin film circuit board. In the process of pressing the key cap to make the trigger portion of the elastic trigger contact the thin film circuit board, the ring portion of the elastic trigger is elastically deformed, so that the trigger portion does not generate sound due to instantaneous collapse.

在本發明的一實施例中，上述的彈性觸發件更包括一定位部，連接環狀部且位於容置區中。In an embodiment of the invention, the above-mentioned elastic trigger further includes a positioning portion connected to the ring portion and located in the receiving area.

在本發明的一實施例中，上述的彈性觸發件的環狀部具有一外表面。外表面具有一第一斜切面與一第二斜切面。第一斜切面與第二斜切面之間具有一切面夾角，而切面夾角大於60度且小於180度。In an embodiment of the invention, the ring portion of the elastic trigger has an outer surface. The outer surface has a first chamfered surface and a second chamfered surface. The first chamfered plane and the second chamfered plane have an angle between all planes, and the angle between the planes is greater than 60 degrees and less than 180 degrees.

在本發明的一實施例中，上述的第一斜切面的斜率與第二切面的斜率相同或不同。In an embodiment of the invention, the slope of the above-mentioned first chamfered plane is the same as or different from the slope of the second chamfered plane.

在本發明的一實施例中，上述的環狀部的頂面透過點膠或卡扣的方式固定於各個限位部的上表面上。In an embodiment of the present invention, the top surface of the above-mentioned ring portion is fixed on the upper surface of each limiting portion by means of dispensing or snapping.

在本發明的一實施例中，上述的彈性觸發件的材質包括橡膠或塑膠。In an embodiment of the invention, the material of the elastic trigger element includes rubber or plastic.

The keyboard module is disposed on the second body, and includes a thin film circuit board and a plurality of detachable key structures described above.

基於上述，本發明的可拆卸式按鍵結構的觸發件固定於鍵帽上，且壓縮彈簧的一端套設於鍵帽的限位部與觸發件的環狀部，另一端直接接觸薄膜電路板。藉此，在按壓鍵帽而使觸發件的觸發部接觸薄膜電路板的過程中，壓縮彈簧會產生彈性變形。由於壓縮彈簧與薄膜電路板之間沒有距離，因此能夠防止觸發件瞬間潰縮而發出聲響，也不會在按壓可拆卸式按鍵結構的過程中產生段落手感。Based on the above, the trigger of the detachable key structure of the present invention is fixed on the key cap, and one end of the compression spring is sleeved on the limit portion of the key cap and the ring portion of the trigger, and the other end directly contacts the thin film circuit board. Thereby, in the process of pressing the key cap to make the trigger portion of the trigger contact the thin-film circuit board, the compression spring will elastically deform. Since there is no distance between the compression spring and the thin-film circuit board, it can prevent the trigger from collapsing instantaneously and making noise, and it will not produce a paragraph feel during the process of pressing the detachable key structure.

為讓本發明的上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。In order to make the above-mentioned features and advantages of the present invention more obvious and understandable, the embodiments are specifically described below in conjunction with the accompanying drawings for detailed description as follows.

圖1A是依照本發明的一實施例的一種電子裝置的立體示意圖。請參考圖1A，在本實施例中，電子裝置10包括一第一機體20、樞接於第一機體20的一第二機體30以及一鍵盤模組40。鍵盤模組40設置於第二機體30上，且包括一薄膜電路板42以及多個可拆卸式按鍵結構100a。需說明的是，在圖1A中，薄膜電路板42由於位在電子裝置10的內部，故以虛線表示，且其結構與配置僅為示意性地繪出，於此並不加以限制。此處，電子裝置10是以筆記型電腦為例，但本發明不以此為限制。在其他未繪示的實施例中，電子裝置10也可以是手機、平板電腦等其他電子裝置。FIG. 1A is a schematic perspective view of an electronic device according to an embodiment of the invention. Please refer to FIG. 1A. In this embodiment, the electronic device 10 includes a first body 20, a second body 30 pivotally connected to the first body 20, and a keyboard module 40. The keyboard module 40 is disposed on the second body 30 and includes a thin film circuit board 42 and a plurality of detachable key structures 100a. It should be noted that, in FIG. 1A, the thin film circuit board 42 is located inside the electronic device 10, so it is indicated by a dotted line, and its structure and configuration are only schematically shown, and are not limited herein. Here, the electronic device 10 is a notebook computer as an example, but the invention is not limited thereto. In other embodiments not shown, the electronic device 10 may also be other electronic devices such as mobile phones and tablet computers.

圖1B是圖1A的電子裝置中的一個可拆卸式按鍵結構的放大立體示意圖。圖1C是圖1B的可拆卸式按鍵結構在另一視角的立體示意圖。圖1D是圖1C的可拆卸式按鍵結構的立體分解示意圖。圖1E是圖1C的可拆卸式按鍵結構的剖面示意圖。請同時參考圖1B、圖1C、圖1D與圖1E，在本實施例中，可拆卸式按鍵結構100a包括一鍵帽110、一觸發件120a以及一壓縮彈簧130。鍵帽110包括彼此分離的兩個弧形的限位部111a，其中這些限位部111a定義出一容置區112，且每一個限位部111a具有一上表面113。需說明的是，在其他實施例中，限位部111a的數量及形狀可以適當地調整，本發明對此不作限制。FIG. 1B is an enlarged schematic perspective view of a detachable key structure in the electronic device of FIG. 1A. FIG. 1C is a perspective schematic view of the detachable key structure of FIG. 1B from another perspective. FIG. 1D is an exploded perspective view of the detachable key structure of FIG. 1C. FIG. 1E is a schematic cross-sectional view of the detachable key structure of FIG. 1C. Please refer to FIGS. 1B, 1C, 1D and 1E at the same time. In this embodiment, the detachable key structure 100 a includes a key cap 110, a trigger 120 a and a compression spring 130. The keycap 110 includes two arc-shaped limiting portions 111a separated from each other, wherein the limiting portions 111a define a receiving area 112, and each limiting portion 111a has an upper surface 113. It should be noted that in other embodiments, the number and shape of the limiting portions 111a can be adjusted appropriately, and the present invention does not limit this.

觸發件120a配置於容置區112中，且包括一環狀部122a以及突出於環狀部122a的一觸發部124。在本實施例中，觸發件120a可以採用橡膠圓頂（rubber dome），或者是由矽膠等材質所製成的圓頂結構。如圖1D所示，觸發部124例如是實心的圓柱狀結構，在其他實施例中，可依據形變程度或按壓手感等設計需求，將觸發部124設計為中空的圓柱狀結構，本發明對此不多作限制。環狀部122a承靠並固定於各個限位部111a的上表面113上。壓縮彈簧130具有彼此相對的一第一側131與一第二側132。壓縮彈簧130的第一側131套設於鍵帽110的限位部111a與觸發件120a的環狀部122a，且固定於限位部111a上或環狀部122a上。壓縮彈簧130的第二側132直接接觸薄膜電路板42。亦即，壓縮彈簧130的兩側分別連接鍵帽110與薄膜電路板42。在按壓鍵帽110以使觸發件120a的觸發部124接觸薄膜電路板42的過程中，壓縮彈簧130產生彈性變形，帶動觸發件120a沿著垂直於薄膜電路板42的方向直下運動。藉由上述鍵帽110、觸發件120a以及壓縮彈簧130三者之間的結構配置，能夠避免觸發件120a的觸發部124因瞬間潰縮而產生聲響。The trigger 120a is disposed in the accommodating area 112 and includes an annular portion 122a and a trigger portion 124 protruding from the annular portion 122a. In this embodiment, the trigger member 120a may use a rubber dome or a dome structure made of silicone or other materials. As shown in FIG. 1D, the trigger portion 124 is, for example, a solid cylindrical structure. In other embodiments, the trigger portion 124 can be designed as a hollow cylindrical structure according to the design requirements such as the degree of deformation or the feel of pressing. No more restrictions. The ring-shaped portion 122a bears and is fixed to the upper surface 113 of each stopper 111a. The compression spring 130 has a first side 131 and a second side 132 opposite to each other. The first side 131 of the compression spring 130 is sleeved on the limiting portion 111a of the keycap 110 and the annular portion 122a of the trigger 120a, and is fixed on the limiting portion 111a or the annular portion 122a. The second side 132 of the compression spring 130 directly contacts the thin film circuit board 42. That is, the two sides of the compression spring 130 are respectively connected to the keycap 110 and the thin film circuit board 42. In the process of pressing the keycap 110 to make the trigger portion 124 of the trigger 120 a contact the thin film circuit board 42, the compression spring 130 is elastically deformed, driving the trigger 120 a to move straight down in a direction perpendicular to the thin film circuit board 42. With the structural arrangement among the key cap 110, the trigger 120a and the compression spring 130, the trigger portion 124 of the trigger 120a can be prevented from generating sound due to instantaneous collapse.

在本實施例中，鍵帽110的每個限位部111a具有一外表面114以及設置於外表面114上的一卡勾115。在組裝壓縮彈簧130與鍵帽110時，卡勾115突出於壓縮彈簧130以卡扣壓縮彈簧130的第一側131，藉此使壓縮彈簧130與鍵帽110之間達到固定作用。如圖1D與圖1E所示，在本實施例中，觸發件120a可更包括一定位部126，其中定位部126連接環狀部122a且凸向遠離觸發部124的一側，並位於容置區112中。進一步而言，定位部126的尺寸與容置區112大致相同，透過兩者之間的結構配合，限位部111a的內壁環繞地貼合於定位部126的外壁，能夠避免觸發件120a的位置發生偏移，進而防止觸發件120a脫落於鍵帽110。為了更進一步的固定觸發件120a與鍵帽110，可在限位部111a的上表面113上塗佈黏著層50，使觸發件120a的環狀部122a透過點膠的方式固定於各個限位部111a的上表面113上。當然，在其他未繪示的實施例中，觸發件的環狀部與限位部之間可透過其他的固定方式來固定，例如是卡扣的方式，因此不以上述的點膠方式為限。In this embodiment, each limiting portion 111 a of the keycap 110 has an outer surface 114 and a hook 115 disposed on the outer surface 114. When assembling the compression spring 130 and the key cap 110, the hook 115 protrudes from the compression spring 130 to catch the first side 131 of the compression spring 130, thereby achieving a fixing effect between the compression spring 130 and the key cap 110. As shown in FIGS. 1D and 1E, in this embodiment, the trigger 120a may further include a positioning portion 126, wherein the positioning portion 126 is connected to the ring portion 122a and protrudes toward a side away from the trigger portion 124, and is located in the housing District 112. Further, the size of the positioning portion 126 is substantially the same as that of the accommodating area 112. Through the structural cooperation between the two, the inner wall of the limiting portion 111a is circumferentially attached to the outer wall of the positioning portion 126, which can prevent the trigger 120a from The position shifts to prevent the trigger 120a from falling off the keycap 110. In order to further fix the trigger 120a and the keycap 110, an adhesive layer 50 can be coated on the upper surface 113 of the limiting portion 111a, so that the annular portion 122a of the trigger 120a is fixed to each limiting portion by dispensing 111a on the upper surface 113. Of course, in other embodiments not shown, the ring portion and the limiting portion of the trigger can be fixed by other fixing methods, such as a snap-fit method, so the above dispensing method is not limited .

在使用者透過本發明的電子裝置10的鍵盤模組40進行輸入作業時，可拆卸式按鍵結構100a的鍵帽110受力按壓，驅使觸發件120a的觸發部124與薄膜電路板42接觸。在按壓的過程中，壓縮彈簧130會產生彈性變形，且由於壓縮彈簧130的第二側132是直接接觸薄膜電路板42，因此能夠防止觸發件120a瞬間潰縮而發出聲響，也不會在按壓可拆卸式按鍵結構100a的過程中產生段落手感。此外，若可拆卸式按鍵結構100a有破損或喪失功能的情況時，可直接將單個可拆卸式按鍵結構100a從鍵盤模組40中拆卸下來並進行更換，即同時將組裝在一起的鍵帽110、觸發件120a以及壓縮彈簧130從鍵盤模組40中取下。When a user performs an input operation through the keyboard module 40 of the electronic device 10 of the present invention, the keycap 110 of the detachable key structure 100a is pressed by force to drive the trigger portion 124 of the trigger 120a to contact the thin film circuit board 42. During the pressing process, the compression spring 130 is elastically deformed, and since the second side 132 of the compression spring 130 directly contacts the thin film circuit board 42, it can prevent the trigger 120a from instantaneously collapsing and making a sound, and will not be pressed The detachable key structure 100a generates a paragraph feel during the process. In addition, if the detachable key structure 100a is damaged or loses its function, the single detachable key structure 100a can be directly removed from the keyboard module 40 and replaced, that is, the assembled keycap 110 , The trigger 120a and the compression spring 130 are removed from the keyboard module 40.

圖2A是本發明的一實施例的一種可拆卸式按鍵結構的立體分解示意圖。圖2B是圖2A的可拆卸式按鍵結構的剖面示意圖。請參考圖2A與圖2B，本實施例的可拆卸式按鍵結構100b與圖1D的可拆卸式按鍵結構100a大致相似，主要差異在於：在本實施例的限位部111b的外表面沒有設置卡勾。觸發件120b的環狀部122b具有一外表面122b1以及設置於外表面122b1上的徑向延伸的兩個凸塊122b2。這些凸塊122b2突出於壓縮彈簧130以卡扣壓縮彈簧130的第一側131。需說明的是，在其他實施例中，凸塊122b2的形狀及數量可以調整，只要能使壓縮彈簧130達到固定作用即可，本發明對此不作限制。2A is an exploded perspective view of a detachable key structure according to an embodiment of the invention. 2B is a schematic cross-sectional view of the detachable key structure of FIG. 2A. 2A and 2B, the detachable key structure 100b of this embodiment is substantially similar to the detachable key structure 100a of FIG. 1D, the main difference is that no card is provided on the outer surface of the limiting portion 111b of this embodiment hook. The annular portion 122b of the trigger 120b has an outer surface 122b1 and two radially extending protrusions 122b2 disposed on the outer surface 122b1. The protrusions 122b2 protrude from the compression spring 130 to catch the first side 131 of the compression spring 130. It should be noted that in other embodiments, the shape and number of the protrusions 122b2 can be adjusted, as long as the compression spring 130 can achieve a fixed effect, and the present invention does not limit this.

圖3A是本發明的另一實施例的一種可拆卸式按鍵結構的立體分解示意圖。圖3B是圖3A的可拆卸式按鍵結構的剖面示意圖。請參考圖3A與圖3B，本實施例的可拆卸式按鍵結構100c與圖2A的可拆卸式按鍵結構100b主要差異在於：本實施例中的可拆卸式按鍵結構100c以彈性觸發件120c來取代圖2A中的觸發件120b與壓縮彈簧130。FIG. 3A is an exploded perspective view of a detachable key structure according to another embodiment of the invention. 3B is a schematic cross-sectional view of the detachable key structure of FIG. 3A. Please refer to FIGS. 3A and 3B. The main difference between the detachable key structure 100c in this embodiment and the detachable key structure 100b in FIG. 2A is that the detachable key structure 100c in this embodiment is replaced by an elastic trigger 120c The trigger 120b and the compression spring 130 in FIG. 2A.

詳細來說，在本實施例中，彈性觸發件120c的材質例如是橡膠或塑膠，其配置於容置區112中，且包括一觸發部124c以及圍繞觸發部124c的一環狀部122c。具體而言，觸發部124c的長度L2小於環狀部122c的長度L1。觸發部124c的末端大致呈現錐狀，但需說明的是，本發明對觸發件124c的形狀不加以限制。環狀部122c具有彼此相對的一頂面125與一底面127。環狀部122c的頂面125承靠並固定於各個限位部111c的上表面113上。環狀部122c的底面127直接接觸薄膜電路板42（繪示於圖1B）。在按壓鍵帽110以使彈性觸發件120c的觸發部124c接觸薄膜電路板42的過程中，彈性觸發件120c的環狀部122c產生彈性變形，使觸發部124c不會因瞬間潰縮而產生聲響。In detail, in this embodiment, the material of the elastic trigger 120c is, for example, rubber or plastic, which is disposed in the accommodating area 112 and includes a trigger portion 124c and an annular portion 122c surrounding the trigger portion 124c. Specifically, the length L2 of the trigger portion 124c is smaller than the length L1 of the ring portion 122c. The tip of the trigger portion 124c is generally tapered, but it should be noted that the present invention does not limit the shape of the trigger 124c. The annular portion 122c has a top surface 125 and a bottom surface 127 opposite to each other. The top surface 125 of the ring-shaped portion 122c bears and is fixed to the upper surface 113 of each restricting portion 111c. The bottom surface 127 of the annular portion 122c directly contacts the thin film circuit board 42 (shown in FIG. 1B). In the process of pressing the key cap 110 to make the trigger portion 124c of the elastic trigger 120c contact the thin film circuit board 42, the annular portion 122c of the elastic trigger 120c is elastically deformed so that the trigger portion 124c does not generate sound due to instantaneous collapse .

圖4A是本發明的另一實施例的一種可拆卸式按鍵結構的立體分解示意圖。圖4B是圖4A的可拆卸式按鍵結構的剖面示意圖。請參考圖4A與圖4B，本實施例的可拆卸式按鍵結構100d與圖3A的可拆卸式按鍵結構100c大致相似，主要差異在於，本實施例中的可拆卸式按鍵結構100d的彈性觸發件120d的環狀部122d的形狀非柱狀體。在本實施例中，彈性觸發件120d的環狀部122d具有一外表面123，且外表面123具有一第一斜切面S1與一第二斜切面S2。在本實施例中，第一斜切面S1的斜率與第二切面S2的斜率相同，且第一斜切面S1與第二斜切面S2之間具有一切面夾角θ。此處，切面夾角θ大於60度且小於180度。需說明的是，在其他實施例中，第一斜切面S1的斜率也可以不同於第二切面S2的斜率，本發明對此不作限制。4A is an exploded perspective view of a detachable key structure according to another embodiment of the invention. 4B is a schematic cross-sectional view of the detachable key structure of FIG. 4A. 4A and 4B, the detachable key structure 100d of this embodiment is substantially similar to the detachable key structure 100c of FIG. 3A, the main difference is that the elastic trigger of the detachable key structure 100d in this embodiment The shape of the annular portion 122d of 120d is non-columnar. In this embodiment, the annular portion 122d of the elastic trigger 120d has an outer surface 123, and the outer surface 123 has a first chamfered surface S1 and a second chamfered surface S2. In this embodiment, the slope of the first chamfered plane S1 is the same as the slope of the second chamfered plane S2, and the first chamfered plane S1 and the second chamfered plane S2 have an angle θ between all planes. Here, the angle θ of the tangent plane is larger than 60 degrees and smaller than 180 degrees. It should be noted that, in other embodiments, the slope of the first slanted plane S1 may also be different from the slope of the second slanted plane S2, which is not limited in the present invention.

簡言之，本實施例的可拆卸式按鍵結構100d的彈性觸發件120d的底面127直接接觸薄膜電路板42（請參考圖1B）。藉此，在按壓鍵帽110而使彈性觸發件120d的觸發部124c接觸薄膜電路板42的過程中，彈性觸發件120d的環狀部122d會產生彈性變形。由於彈性觸發件120d的環狀部122d與薄膜電路板42之間沒有距離，因此能夠防止彈性觸發件120d的觸發部124c瞬間潰縮而發出聲響，也不會在按壓可拆卸式按鍵結構100d的過程中產生段落手感。In short, the bottom surface 127 of the elastic trigger 120d of the detachable key structure 100d of this embodiment directly contacts the thin film circuit board 42 (please refer to FIG. 1B ). Therefore, when the key cap 110 is pressed to make the trigger portion 124c of the elastic trigger 120d contact the thin film circuit board 42, the annular portion 122d of the elastic trigger 120d is elastically deformed. Since there is no distance between the annular portion 122d of the elastic trigger 120d and the thin film circuit board 42, the trigger portion 124c of the elastic trigger 120d can be prevented from instantaneously collapsing and making a sound, and it will not press the removable key structure 100d. The paragraph feels in the process.

綜上所述，本發明的可拆卸式按鍵結構是採用觸發部觸發薄膜電路板，其中是以壓縮彈簧或彈性觸發件的環狀部直接接觸薄膜電路板。也就是說，薄膜電路板與壓縮彈簧之間或與彈性觸發件之間不存在落差。如此一來，在按壓鍵帽而使觸發部接觸薄膜電路板的過程中，壓縮彈簧或彈性觸發件的環狀部會產生彈性變形。由於壓縮彈簧或彈性觸發件與薄膜電路板之間沒有距離，因此能夠防止觸發部瞬間潰縮而發出聲響，也不會在按壓可拆卸式按鍵結構的過程中產生段落手感。In summary, the detachable key structure of the present invention uses a trigger portion to trigger the thin film circuit board, wherein the ring portion of the compression spring or elastic trigger directly contacts the thin film circuit board. In other words, there is no drop between the thin film circuit board and the compression spring or the elastic trigger. In this way, in the process of pressing the key cap to make the trigger part contact the thin-film circuit board, the compression spring or the ring part of the elastic trigger will be elastically deformed. Since there is no distance between the compression spring or the elastic trigger and the thin film circuit board, the trigger part can be prevented from instantaneously collapsing and making a sound, and there is no paragraph feel during the process of pressing the removable key structure.
