Description
本發明是有關於一種鍵帽，且特別是有關於一種可提供霧化效果的鍵帽。 The present invention relates to a keycap, and more particularly to a keycap that provides an atomizing effect.
市面上的鍵盤有些具有背光功能，可以讓使用者在黑暗環境下使用。然而，由於有些鍵帽本身的顏色較淡，因此從鍵帽上方可看得到鍵帽下方的結構，影響鍵盤的外觀美感。 Some of the keyboards on the market have a backlight function that allows users to use them in dark environments. However, since some of the keycaps are light in color, the structure under the keycap can be seen from above the keycap, which affects the aesthetic appearance of the keyboard.
因此，亟需提出一種鍵帽，既可讓光線射出，同時可避免從鍵帽上方可看得到鍵帽下方的結構陰影。 Therefore, it is urgent to propose a key cap that allows light to be emitted while avoiding structural shadows under the keycap from above the keycap.
因此，本發明提出一種鍵帽，具有霧化結構，可避免鍵帽下方的結構被看見。 Accordingly, the present invention provides a keycap having an atomizing structure that prevents the structure under the keycap from being seen.

The key cap includes a light transmissive cap, an atomizing structure and a coating layer. The light transmissive cap has an inner bottom surface and an outer top surface. The atomizing structure is formed on the inner bottom surface. The coating layer is formed on the outer top surface and has a hollow pattern. The area of the hollow pattern corresponds to the area of the atomization structure.
根據本發明之另一實施例，提出一種鍵帽。鍵帽包括一透光帽體、一霧化結構及一塗佈層。透光鍵帽具有一外頂 面。霧化結構分布於透光鍵帽的內部。塗佈層形成於外頂面且具有一鏤空圖案，鏤空圖案的區域與霧化結構的區域相對應。 According to another embodiment of the invention, a keycap is proposed. The key cap includes a light transmissive cap, an atomizing structure and a coating layer. Light-transmitting keycap has an outer top surface. The atomizing structure is distributed inside the light-transmitting keycap. The coating layer is formed on the outer top surface and has a hollow pattern, and the area of the hollow pattern corresponds to the area of the atomization structure.
為了對本發明之上述及其他方面有更佳的瞭解，下文特舉較佳實施例，並配合所附圖式，作詳細說明如下： In order to better understand the above and other aspects of the present invention, the preferred embodiments are described below, and in conjunction with the drawings, the detailed description is as follows:

第2圖繪示依照本發明一實施例之鍵盤的局部剖視圖。 2 is a partial cross-sectional view of a keyboard in accordance with an embodiment of the present invention.
第1圖繪示依照本發明一實施例之鍵盤100的局部剖視圖。鍵盤100包括底板110、至少一支撐機構120、薄膜開關層130、至少一彈性體140、至少一鍵帽150及導光板160。為了避免圖示過於複雜，第1圖的支撐機構120、彈性體140及鍵帽150僅繪示單個，然另一實施例中，支撐機構120、彈性體140及鍵帽150個別的數量可以等於或超過二個。 1 is a partial cross-sectional view of a keyboard 100 in accordance with an embodiment of the present invention. The keyboard 100 includes a bottom plate 110, at least one support mechanism 120, a membrane switch layer 130, at least one elastic body 140, at least one keycap 150, and a light guide plate 160. In order to avoid the complexity of the illustration, the support mechanism 120, the elastic body 140 and the key cap 150 of FIG. 1 are only shown as a single one. However, in another embodiment, the number of the support mechanism 120, the elastic body 140 and the key cap 150 may be equal to one. Or more than two.
支撐機構120設置於底板110與鍵帽150之間，用以升降鍵帽150。鍵帽150能上、下移動地連接於底板110之上方，致使鍵帽150相對於底板110於未按壓位置與按壓位置之間移動。如第1圖所示，支撐機構120例如是剪刀腳機構。 The support mechanism 120 is disposed between the bottom plate 110 and the key cap 150 for lifting the key cap 150. The keycap 150 is movably coupled above and below the bottom plate 110 such that the keycap 150 moves relative to the bottom plate 110 between the unpressed position and the depressed position. As shown in Fig. 1, the support mechanism 120 is, for example, a scissor mechanism.
薄膜開關層130設於底板110上。薄膜開關層130包括第一層131、間隔層132、第二層133、第一接點134及第二接點135，其中，間隔層132位於第一層131與第二層133之間，第一接點134位於第一層131上，第二接點135位於第二層133上。當按壓鍵帽150往下時，彈性體 140抵壓薄膜開關層130，使第一接點134與第二接點135彼此電性接觸，以傳送按壓訊號給一電路板(未繪示)。 The membrane switch layer 130 is disposed on the bottom plate 110. The membrane switch layer 130 includes a first layer 131, a spacer layer 132, a second layer 133, a first contact 134, and a second contact 135. The spacer layer 132 is located between the first layer 131 and the second layer 133. A contact 134 is located on the first layer 131 and a second contact 135 is located on the second layer 133. Elastomer when pressing the keycap 150 down The first switch 134 and the second contact 135 are electrically connected to each other to transmit a pressing signal to a circuit board (not shown).
彈性體140設於鍵帽150與薄膜開關層130之間。當鍵帽150被按壓時，抵壓彈性體140使其形變，以提供鍵帽15一彈性回復力。如此一來，當釋放鍵帽150時，鍵帽150得以復位。 The elastic body 140 is disposed between the keycap 150 and the membrane switch layer 130. When the keycap 150 is pressed, the elastic body 140 is pressed to deform it to provide the keycap 15 with an elastic restoring force. As such, when the keycap 150 is released, the keycap 150 is reset.
鍵帽150包括透光帽體151、霧化結構153及塗佈層152。透光帽體151具有內底面151b及外頂面151u。塗佈層152形成於透光帽體151的外頂面151u。塗佈層152具有鏤空圖案152a，使背光模組(未繪示)的光線L1在穿透透光帽體151後可從鏤空圖案152a出光，使鍵帽150呈現發光狀態。 The keycap 150 includes a light transmissive cap 151, an atomizing structure 153, and a coating layer 152. The light transmissive cap 151 has an inner bottom surface 151b and an outer top surface 151u. The coating layer 152 is formed on the outer top surface 151u of the light transmissive cap 151. The coating layer 152 has a hollow pattern 152a, so that the light L1 of the backlight module (not shown) can be emitted from the hollow pattern 152a after passing through the transparent cap 151, so that the key cap 150 assumes a light-emitting state.
此外，鏤空圖案152a的區域與霧化結構153的區域相對應；例如，霧化結構153的區域面積與鏤空圖案152a的區域面積可大致上相等，或者，霧化結構153的區域面積大於鏤空圖案152a的區域面積。在本實施例中，霧化結構153形成於透光帽體151的整個內底面151b，然亦可集中地形成於內底面151b的局部。 Further, the area of the hollow pattern 152a corresponds to the area of the atomizing structure 153; for example, the area of the area of the atomizing structure 153 may be substantially equal to the area of the area of the hollow pattern 152a, or the area of the area of the atomizing structure 153 may be larger than the hollow pattern. The area of the area of 152a. In the present embodiment, the atomizing structure 153 is formed on the entire inner bottom surface 151b of the light transmissive cap 151, but may be collectively formed on a portion of the inner bottom surface 151b.
塗佈層152形成於外頂面151u。本實施例中，塗佈層152直接形成於外頂面151u，也就是說，塗佈層152與透光帽體151之間不具任何中介層。 The coating layer 152 is formed on the outer top surface 151u. In this embodiment, the coating layer 152 is directly formed on the outer top surface 151u, that is, there is no interposer between the coating layer 152 and the transparent cap 151.
塗佈層152較佳係淡色層，例如是白色、灰色、銀色等。。本實施例中，霧化結構153形成於透光帽體151的內底面151b。 The coating layer 152 is preferably a light color layer such as white, gray, silver or the like. . In the present embodiment, the atomizing structure 153 is formed on the inner bottom surface 151b of the light transmissive cap 151.
霧化結構153可提供一霧化效果。詳細來說，入射至霧化結構153的光線L1會發生散射而產生霧化效果。如此一來，即使透光帽 體151及/或塗佈層152係可透光，透光帽體151內的結構(如彈性體140及/或支撐機構120)也不會從鏤空圖案152a露出。一實施例中，霧化結構153的剖面可以是圓形的一部分、橢圓形的一部分、多邊形的一部分或其組合。然，本發明實施例並不限定霧化結構153的剖面形狀，只要其可提供霧化效果即可。 The atomizing structure 153 can provide an atomizing effect. In detail, the light L1 incident on the atomizing structure 153 is scattered to generate an atomizing effect. So that even the light-transmissive cap The body 151 and/or the coating layer 152 are light transmissive, and the structures in the light transmissive cap 151 (such as the elastomer 140 and/or the support mechanism 120) are not exposed from the hollow pattern 152a. In one embodiment, the cross-section of the atomizing structure 153 can be a portion of a circle, a portion of an ellipse, a portion of a polygon, or a combination thereof. However, the embodiment of the present invention does not limit the cross-sectional shape of the atomizing structure 153 as long as it can provide an atomizing effect.
霧化結構153例如是粗糙結構，其突出地形成於透光帽體151的內底面151b。另一實施例中，霧化結構153可具有咬花圖案，同樣可提供霧化效果。此外，霧化結構153與透光帽體151可於同一製程中一併形成。例如，霧化結構153與透光帽體151可採用塑膠射出製程一體成形。在射出製程中，射出模具的模穴內壁可具有對應霧化結構153的結構，使塑膠材料冷凝形成透光帽體151時，可同時形成霧化結構153。只要是可形成粗糙的霧化結構153即可，本發明實施例不限定霧化結構153的形成方式。 The atomizing structure 153 is, for example, a rough structure that is protrudedly formed on the inner bottom surface 151b of the light transmissive cap 151. In another embodiment, the atomizing structure 153 can have a bite pattern, which can also provide a fogging effect. In addition, the atomizing structure 153 and the light transmissive cap 151 can be formed together in the same process. For example, the atomizing structure 153 and the light transmissive cap 151 can be integrally formed by a plastic injection process. In the injection process, the inner wall of the cavity for injecting the mold may have a structure corresponding to the atomizing structure 153. When the plastic material is condensed to form the transparent cap 151, the atomizing structure 153 may be simultaneously formed. The embodiment of the present invention does not limit the manner in which the atomizing structure 153 is formed as long as it is a rough atomizing structure 153.
導光板160位於底板110下方。導光板160可引導光線L1從導光板160的上表面160u出光。上述底板110具有至少一破孔110a，從導光板160的上表面160u出光的光線L1透過破孔110a射向透光帽體151並從鏤空圖案152a出光。 The light guide plate 160 is located below the bottom plate 110. The light guide plate 160 can guide the light L1 to emit light from the upper surface 160u of the light guide plate 160. The bottom plate 110 has at least one hole 110a, and the light L1 emitted from the upper surface 160u of the light guide plate 160 is transmitted through the hole 110a to the light-transmitting cap 151 and is emitted from the hollow pattern 152a.
第2圖繪示依照本發明一實施例之鍵盤200的局部剖視圖。鍵盤200包括底板110、至少一支撐機構120、薄膜開關層130、至少一彈性體140、至少一鍵帽250及導光板160。 2 is a partial cross-sectional view of a keyboard 200 in accordance with an embodiment of the present invention. The keyboard 200 includes a bottom plate 110, at least one supporting mechanism 120, a membrane switch layer 130, at least one elastic body 140, at least one keycap 250, and a light guide plate 160.
鍵帽250包括透光帽體151、霧化結構253及塗佈層152。與上述實施例不同的是，本實施例的霧化結構253係顆粒狀，其分布 或摻雜於透光帽體151的內部。一實施例中，霧化結構253係二氧化鈦或其它合適的霧化顆粒。就材質而言，霧化結構253可以是純金屬、合金、塑膠或其組合。 The keycap 250 includes a light transmissive cap 151, an atomizing structure 253, and a coating layer 152. Different from the above embodiment, the atomization structure 253 of the present embodiment is granular, and its distribution Or doped in the interior of the light transmissive cap 151. In one embodiment, the atomizing structure 253 is titanium dioxide or other suitable atomized particles. In terms of material, the atomizing structure 253 can be a pure metal, an alloy, a plastic, or a combination thereof.
霧化結構253的區域與透光帽體151的鏤空圖案152a的區域相對應。本實施例中，霧化結構253均勻地分布於透光帽體151的內部；另一實施例中，霧化結構253可集中地分布於透光帽體151的一局部。 The area of the atomizing structure 253 corresponds to the area of the hollow pattern 152a of the light transmissive cap 151. In this embodiment, the atomization structure 253 is evenly distributed inside the light transmissive cap 151. In another embodiment, the atomization structure 253 can be concentratedly distributed on a portion of the transmissive cap 151.
霧化結構253可提供霧化效果，如此一來，即使透光帽體151及/或塗佈層152係可透光，透光帽體151內部的結構也不會從鏤空圖案152a露出。 The atomizing structure 253 can provide an atomizing effect, so that even if the light transmissive cap 151 and/or the coating layer 152 are transparent, the structure inside the translucent cap 151 is not exposed from the hollow pattern 152a.
綜合上述，由於本發明實施例的霧化結構，使透光帽體的內 部結構不致從鏤空圖案顯示出來。一實施例中，霧化結構可以是形成於透光帽體表面的粗糙結構；另一實施例中，霧化結構可以是分布於透光帽體內部的顆粒；再一實施例中，同一鍵帽可同時包含前述二種霧化結構。 In summary, due to the atomization structure of the embodiment of the present invention, the inside of the light transmissive cap is made The structure of the part is not displayed from the cutout pattern. In one embodiment, the atomizing structure may be a rough structure formed on the surface of the light transmissive cap; in another embodiment, the atomizing structure may be particles distributed inside the translucent cap; in another embodiment, the same key The cap can contain both of the aforementioned atomization structures.
綜上所述，雖然本發明已以較佳實施例揭露如上，然其並非用以限定本發明。本發明所屬技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作各種之更動與潤飾。因此，本發明之保護範圍當視後附之申請專利範圍所界定者為準。 In conclusion, the present invention has been disclosed in the above preferred embodiments, and is not intended to limit the present invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
