為讓本發明之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。The above described features and advantages of the present invention will be more apparent from the following description.
圖1是依照本發明之一實施例之一種可攜式電子裝置的俯視圖。請參考圖1,本實施例之可攜式電子裝置10包括一顯示模組100及一鍵盤模組200。鍵盤模組200電性連接至顯示模組100。1 is a top plan view of a portable electronic device in accordance with an embodiment of the present invention. Referring to FIG. 1 , the portable electronic device 10 of the present embodiment includes a display module 100 and a keyboard module 200 . The keyboard module 200 is electrically connected to the display module 100.
圖2是圖1之鍵盤模組200的局部放大圖,而圖3是圖2之沿I-I線的剖面放大圖。請參考圖2及圖3,本實施例之鍵盤模組200包括一電路板210、一導光層220、一裝飾層230及至少一按鍵片240。電路板210具有至少一觸壓開關212。導光層220設置於電路板210上,以導引光線,其中觸壓開關212位於導光層220下。裝飾層230係以膠合方式設置於導光層220上並具有至少一開口232,且開口232的位置對應於觸壓開關212的位置。按鍵片240設置於導光層220上且位於開口232中,按鍵片240具有一透光圖案244a使來自導光層220的光線能從每一按鍵片240的透光圖案244a射出。2 is a partial enlarged view of the keyboard module 200 of FIG. 1, and FIG. 3 is an enlarged cross-sectional view taken along line I-I of FIG. 2. Referring to FIG. 2 and FIG. 3 , the keyboard module 200 of the embodiment includes a circuit board 210 , a light guiding layer 220 , a decorative layer 230 , and at least one button piece 240 . The circuit board 210 has at least one touch switch 212. The light guiding layer 220 is disposed on the circuit board 210 to guide the light, wherein the touch switch 212 is located under the light guiding layer 220. The decorative layer 230 is glued to the light guiding layer 220 and has at least one opening 232, and the position of the opening 232 corresponds to the position of the touch switch 212. The key sheet 240 is disposed on the light guiding layer 220 and located in the opening 232. The key sheet 240 has a light transmitting pattern 244a for allowing light from the light guiding layer 220 to be emitted from the light transmitting pattern 244a of each of the key sheets 240.
在本實施例中,鍵盤模組200更可包括一光源250,其配設於導光層220的側緣,以供應光線至導光層220。光源250可為發光二極體等。在另一未繪示的實施例中,亦可藉由可攜式電子裝置的其他光源來供應光線至導光層220。In this embodiment, the keyboard module 200 further includes a light source 250 disposed on a side edge of the light guiding layer 220 to supply light to the light guiding layer 220. The light source 250 may be a light emitting diode or the like. In another embodiment, the light source is also supplied to the light guiding layer 220 by other light sources of the portable electronic device.
在本實施例中,觸壓開關212由形成在電路板210上的一電極212a和一金屬圓蓋(metal dome)212b所組成。金屬圓蓋212b的頂部係可鄰近或抵觸於導光層220的下表面,因此當使用者施力按壓按鍵片240時,導光層220會將施力轉往金屬圓蓋212b按壓,使金屬圓蓋212b可電性接觸並導通該電極212a。此外,金屬圓蓋212b可用來提供使用者按壓時的觸覺回饋,以方便使用者知道是否按壓成功。In the present embodiment, the touch switch 212 is composed of an electrode 212a formed on the circuit board 210 and a metal dome 212b. The top of the metal dome 212b can be adjacent to or in contact with the lower surface of the light guiding layer 220. Therefore, when the user presses the button piece 240, the light guiding layer 220 will press the force to the metal dome 212b to press the metal. The dome 212b can electrically contact and conduct the electrode 212a. In addition, the metal dome 212b can be used to provide tactile feedback when the user presses to facilitate the user to know whether the pressing is successful.
為了預防導光層220的光線自裝飾層230與按鍵片240之間的間隙射出,本實施例之鍵盤模組200更可包括一遮光層260,其配置於導光層220上,且位於裝飾層230與按鍵片240的間隙之間,以遮蔽並避免導光層220所引導的光線由該間隙射出。在本實施例中,為了確保遮光層260的遮光效果,裝飾層230與遮光層260部分交疊,且按鍵片240與遮光層260部分交疊。The keyboard module 200 of the present embodiment may further include a light shielding layer 260 disposed on the light guiding layer 220 and located in the decoration for preventing the light of the light guiding layer 220 from being emitted from the gap between the decorative layer 230 and the button sheet 240. Between the layer 230 and the gap of the button sheet 240, the light guided by the light guiding layer 220 is shielded and prevented from being emitted from the gap. In the present embodiment, in order to ensure the light shielding effect of the light shielding layer 260, the decorative layer 230 partially overlaps the light shielding layer 260, and the key sheet 240 and the light shielding layer 260 partially overlap.
在本實施例中,裝飾層230及按鍵片240可透過一膠層270黏合於導光層220上。膠層270之材料包括紫外線硬化膠,但不以此為限。In this embodiment, the decorative layer 230 and the button sheet 240 are adhered to the light guiding layer 220 through a glue layer 270. The material of the glue layer 270 includes ultraviolet curing glue, but is not limited thereto.
在本實施例中,按鍵片240包括一基礎部242及一圖案層244,圖案層244位於基礎部242上並具有透光圖案244a。透光圖案244a為圖樣、字元、符號或上述任意之組合,且穿出於導光層220與基礎部242的光線能從透光圖案244a射出。基礎部242具有可透光性,基礎部242的材質可包括聚碳酸酯(polycarbonate)、聚碳酸酯-烷基苯磺酸鹽(polycarbonate-ABS)或液態橡膠。In this embodiment, the key sheet 240 includes a base portion 242 and a pattern layer 244. The pattern layer 244 is located on the base portion 242 and has a light transmissive pattern 244a. The light transmissive pattern 244a is a pattern, a character, a symbol, or any combination thereof, and the light that has passed through the light guiding layer 220 and the base portion 242 can be emitted from the light transmitting pattern 244a. The base portion 242 is permeable to light, and the material of the base portion 242 may include polycarbonate, polycarbonate-ABS, or liquid rubber.
在本實施例中,可利用模壓(molding)之方式來製作基礎部242。當透光圖案244a為簍空時,在模壓形成基礎部的過程中可使基礎部242的局部伸入透光圖案244a之位置,以填充透光圖案244a。In the present embodiment, the base portion 242 can be fabricated by means of molding. When the light transmissive pattern 244a is hollowed out, a portion of the base portion 242 may be projected into the position of the light transmissive pattern 244a during molding to form the base portion to fill the light transmissive pattern 244a.
由於透光圖案244a之簍空部分被基礎部242所填充,藉由基礎部242之可透光性,可使導光層220的光線能自透光圖案244a射出形成圖案影像,而讓使用者得以利用自按鍵片240所發出的圖案影像來辨識透光圖案244a所代表的字元或符號。Since the hollow portion of the light-transmitting pattern 244a is filled by the base portion 242, the light of the light-guiding layer 220 can be emitted from the light-transmitting pattern 244a to form a pattern image, and the user is allowed to pass through the light-transmissive portion 242. The pattern image emitted from the key sheet 240 can be utilized to identify the character or symbol represented by the light transmissive pattern 244a.
綜上所述,本發明之鍵盤模組具有較小的厚度,故能協助可攜式電子裝置達到薄型化的效果。In summary, the keyboard module of the present invention has a small thickness, so that the portable electronic device can be reduced in thickness.
雖然本發明已以實施例揭露如上,然其並非用以限定本發明,任何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,當可作些許之更動與潤飾,故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。Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
