發光皮套鍵盤及其包覆膜 Illuminated leather keyboard and its cover film

本發明係有關於一種發光皮套鍵盤及其包覆膜,特別是指一種搭配平板電腦或移動式資訊設備使用的皮套式鍵盤所使用的發光皮套鍵盤及其包覆膜。 The invention relates to a luminous holster keyboard and a covering film thereof, in particular to a illuminating holster keyboard and a covering film thereof used in a holster keyboard used with a tablet computer or a mobile information device.

按,現有的皮套式包覆鍵盤的構造為在一鍵盤的框體上覆蓋一層包覆膜,包覆膜將鍵盤的各個按鍵隱藏在包覆膜的下方。包覆膜對應於每一個按鍵的位置分別印製有按鍵案,使得操作者得以辨識每一個按鍵的位置及各個按鍵所代表的符號或指令。包覆膜貼靠於各個按鍵的頂面,而且因為包覆膜具有彈性,因此當操作者按壓包覆膜上的每一個按鍵圖案時,包覆膜受到按壓位置便會下降,進而使得和該按鍵圖案對應的按鍵受到按壓。 According to the prior art, the holster-covered keyboard is constructed by covering a frame of a keyboard with a covering film, and the covering film hides each button of the keyboard under the covering film. The cover film is printed with a button case corresponding to the position of each button, so that the operator can recognize the position of each button and the symbol or command represented by each button. The cover film abuts against the top surface of each button, and because the cover film has elasticity, when the operator presses each button pattern on the cover film, the cover film is pressed to decrease position, thereby The button corresponding to the button pattern is pressed.

現有的皮套式包覆鍵盤使用的包覆膜,其製造方法為在一軟性薄膜基材上利用噴塗方式將包覆膜的底色以及多個按鍵圖案噴塗在薄膜基材的表面,然後再於噴塗完成的基材表面塗布上保護層。 The cover film used in the existing holster-type covered keyboard is manufactured by spraying the base color of the coating film and a plurality of button patterns on the surface of the film substrate by spraying on a soft film substrate, and then spraying A protective layer is applied to the surface of the sprayed substrate.

然而,採用噴塗方式印製按鍵圖案,必須利用印刷按鍵圖案的治具或模具將按鍵圖案噴塗在薄膜基材的表面上,因此使得包覆膜的製造程序複雜,而且必須製作專用的治具或模具,而使成本增加。同時,由於按鍵圖形是利用顏料噴塗方式形成,其表面雖然具有保護層,然而長時間使用噴塗的圖形相當容易磨損或脫落,而造成了按鍵圖形損壞的情形。 However, when the button pattern is printed by spraying, the button pattern must be sprayed on the surface of the film substrate by using a jig or a mold for printing the button pattern, thereby making the manufacturing process of the film complicated, and it is necessary to make a special jig or Molding while making the cost increase. At the same time, since the button pattern is formed by the pigment spraying method, although the surface has a protective layer, the pattern used for a long time is relatively easy to wear or fall off, and the button pattern is damaged.

再者,現有的皮套包覆式鍵盤採用的包覆膜的按鍵圖形是利用顏料噴塗在底色層之上,因此形成的按鍵圖形無法透光,故使得現有的皮套包覆式鍵盤難以設置背光模組,而影響到了鍵盤設計的彈性。 Moreover, the button pattern of the cover film used in the existing holster-covered keyboard is sprayed on the underlying layer by using the pigment, so that the formed button pattern cannot be transmitted, so that the existing holster-covered keyboard is difficult to use. The backlight module is set, which affects the flexibility of the keyboard design.

The cover film 20 abuts against the top surface of each of the buttons 32. As described above, since the cover film 20 has a light-transmissive pattern 22 corresponding to each of the button blocks 21 of each of the buttons 32, each button is pressed. The light transmitted through the top surface of the cover 32 can further penetrate the light-transmitting pattern 22 on the cover film 20, so that each of the light-transmitting patterns 22 on the cover film 20 forms a light-emitting state (please refer to Figure 4).

如圖4所示,本發明的包覆膜20的結構包括:一可透光膜23、一底色層24、一遮蔽層25、及一保護層26。其中所述可透光膜23為透明的軟性薄膜,該可透光膜23可以選用諸如PU(Polyurethane,聚氨酯)、TPU(Thermoplastic Polyurethane熱塑性聚胺基甲酸酯)、PE(Polyethylene聚乙烯)等各類型的透明薄膜材料;所述底色層24,可以為一白色,或為其他淺色(如黃色、青色、水藍色等)的塗料,所述底色層24塗布於可透光膜23的至少一側面上;所述遮蔽層25,設置於所述底色層24相對於所述可透光膜23的另一側面,所述遮蔽層25為一不可透光且和所述底色層24具有明顯 對比色彩(如:黑色、鐵灰、深藍色等)的塗料層,所述透光圖案22成型於所述遮蔽層25上;所述保護層26,設置於遮蔽層25相對於所述底色層24的另外一側面上,所述保護層26可以為一透明的UV硬化塗料,所述保護層26成型後具有透明且耐磨的特性,用以保護遮蔽層25及成型於所述遮蔽層25上的所述透光圖案22。然而,本發明其他實施例中,該可透光膜23與底色層24也可以設計為同一片材料,例如,該可透光膜23採用具有和底色色彩相同顏色的透光材料製成,則當光線穿透該可透光膜23,便能夠顯示出和底色相同的顏色,而使得該可透光膜23和底色層24兩者合併成為同一材料層。 As shown in FIG. 4, the structure of the cover film 20 of the present invention comprises: a light transmissive film 23, a bottom color layer 24, a shielding layer 25, and a protective layer 26. The permeable film 23 is a transparent flexible film, and the permeable film 23 can be selected from, for example, PU (Polyurethane), TPU (Thermoplastic Polyurethane), PE (Polyethylene), and the like. Each type of transparent film material; the under color layer 24 may be a white color, or other light color (such as yellow, cyan, water blue, etc.) coating, the bottom color layer 24 is coated on the light transmissive film The shielding layer 25 is disposed on the other side of the ground color layer 24 relative to the light transmissive film 23, and the shielding layer 25 is a non-transparent and bottom Color layer 24 has obvious a coating layer of contrast color (eg, black, iron ash, dark blue, etc.), the light transmissive pattern 22 being formed on the shielding layer 25; the protective layer 26 being disposed on the shielding layer 25 relative to the ground color On the other side of the layer 24, the protective layer 26 may be a transparent UV hardening coating.

However, in other embodiments of the present invention, the light transmissive film 23 and the ground layer 24 may also be designed as the same piece of material. For example, the light transmissive film 23 is made of a light transmissive material having the same color as the background color. When the light penetrates the light transmissive film 23, the same color as the underlying color can be displayed, so that both the light transmissive film 23 and the underlying layer 24 are combined into the same material layer.

如圖4所示,該實施例中,所述遮蔽層25是利用雷射雕刻方式將遮蔽層25的部分材料移除,形成鏤空圖形,而形成所述透光圖案22。同時,需要注意的是,該實施例中,以雷射雕刻方式成型所述透光圖案22時,必須注意透光圖案22的蝕刻深度僅限於遮蔽層25的厚度範圍內,因此使得透光圖案22不會穿透到底色層24,因此位於透光圖案22範圍內的底色層24能夠保持完整。因此,從按鍵32頂面穿透出的光線L會先穿透過可透光膜23與底色層24之後,再從透光圖案22穿透過遮蔽層25,且使得透光圖案22處顯示出底色層24的背光顏色。 As shown in FIG. 4, in the embodiment, the shielding layer 25 removes part of the material of the shielding layer 25 by laser engraving to form a hollow pattern, and the transparent pattern 22 is formed. At the same time, it should be noted that in the embodiment, when the light-transmitting pattern 22 is formed by laser engraving, it must be noted that the etching depth of the light-transmitting pattern 22 is limited to the thickness of the shielding layer 25, thus making the light-transmitting pattern 22 does not penetrate the bottom color layer 24, so the ground color layer 24 located within the range of the light transmissive pattern 22 can remain intact. Therefore, the light L that has penetrated from the top surface of the button 32 passes through the light-transmitting film 23 and the ground layer 24, and then passes through the shielding layer 25 from the light-transmitting pattern 22, so that the light-transmitting pattern 22 is displayed. The backlight color of the underlying layer 24.

如圖5所示的實施例,則是進一步地在包覆膜20上對應於多個所述按鍵32頂面的位置分別設置多個容納部28,每一個容納部對應於多個所述按鍵32頂面,因此使得多個所述按鍵32的頂面能夠容置在各個容納部28之中。該實施例中,包覆膜20透過多個容納部28和按鍵32相互銜接,因此能夠消除包覆膜20和按鍵32之間橫向的相對位移,增加包覆膜20的各個透光圖案22的定位精確度。同時,透過多個所述容納部28,也能夠使得包覆膜20的外觀具有類似實體按鍵的凸出形狀,而使得操作者易於辨識各個按鍵的位置。 In the embodiment shown in FIG. 5, a plurality of accommodating portions 28 are respectively disposed on the cover film 20 at positions corresponding to the top surfaces of the plurality of the buttons 32, and each of the accommodating portions corresponds to the plurality of the buttons. The top surface of the 32, so that the top surfaces of the plurality of the buttons 32 can be accommodated in the respective housing portions 28. In this embodiment, the cover film 20 is coupled to each other through the plurality of receiving portions 28 and the buttons 32, thereby eliminating lateral displacement between the cover film 20 and the button 32, and increasing the respective light-transmitting patterns 22 of the cover film 20.
