本創作係提供一種具防水功能之可調校式鍵盤，尤指軟性電路板上表面為結合有包覆定位於發光元件外部之透光隔絕膜，以加強防水之效果，並由軟性電路板下表面之脈寬調變控制晶片伸入於按鍵組件在底板之破孔內，可節省佔用的高度使整體更為薄型化。 The present invention provides an adjustable keyboard with waterproof function, especially the surface of the flexible circuit board is combined with a light-transmissive insulating film which is coated and disposed outside the light-emitting element to enhance the waterproof effect and is provided by a flexible circuit board. The surface pulse width modulation control wafer protrudes into the hole of the key assembly in the bottom plate, which can save the occupied height and make the whole thinner.
按，現今電子科技與資訊產業的快速發展，使各種電子產品皆朝向輕、薄、短、小且功能強大的趨勢發展，如電腦、筆記型電腦、行動上網裝置(MID)、智慧型手機、平板電腦等，已成為現代人在日常生活或工作上所不可或缺的電子產品，而使用者與電子產品之間大多是使用滑鼠、鍵盤等輸入裝置來溝通，其中又以鍵盤最為方便作文字、數字或指令的輸入操作，並提昇實用的功能。 According to the rapid development of today's electronic technology and information industry, various electronic products are moving toward light, thin, short, small and powerful trends, such as computers, notebook computers, mobile Internet devices (MIDs), smart phones, Tablet PCs, etc., have become indispensable electronic products for modern people in daily life or work, and most of the users and electronic products use mouse, keyboard and other input devices to communicate, and the keyboard is most convenient. Input operations for text, numbers, or commands, and enhance useful functions.
再者，為了在光線不足的環境下能使人眼清楚的看到每個按鍵上的符號，便有業者在鍵盤中導入導光板及光源技術，並發展出具背光模組之發光鍵盤，使背光模組所產生之光線可投射到每個鍵帽的背面處形成背光效果，讓使用者可看清楚鍵帽上的字元符號，以方便操作使用，而目前市面上之發光鍵盤包括有背光模組及按鍵模組，其中該背光模組為具有一導光板，並於導光板一側處設有光源，且光源之發光二極體為面向 導光板投射出光線使導光板均勻的發光，又導光板下表面設有可將導光板下表面所射出光線反射回導光板上之反光片，並於導光板上表面設有對應於按鍵模組處之遮光片，便可將導光板導引射出的光線穿過遮光片之透光部後，再入射至按鍵模組對應之鍵帽上形成背光。 Moreover, in order to enable the human eye to clearly see the symbols on each button in a low-light environment, a manufacturer introduces a light guide plate and a light source technology into the keyboard, and develops an illuminated keyboard with a backlight module to make the backlight The light generated by the module can be projected onto the back of each keycap to form a backlight effect, so that the user can see the character symbols on the keycap for convenient operation. Currently, the illuminated keyboard on the market includes a backlight module. And a button module, wherein the backlight module has a light guide plate, and a light source is disposed at one side of the light guide plate, and the light emitting diode of the light source is facing The light guide plate projects light to make the light guide plate uniformly emit light, and the lower surface of the light guide plate is provided with a reflective sheet which can reflect the light emitted from the lower surface of the light guide plate back to the light guide plate, and is provided with a corresponding button module on the surface of the light guide plate. The light-shielding sheet can pass the light guided by the light guide plate through the light-transmitting portion of the light-shielding sheet, and then enter the key cap corresponding to the button module to form a backlight.
由於發光鍵盤使用至今已經好幾十年，使發光鍵盤的技術已經十分成熟，而在發光鍵盤內部結構非常簡化的情況下，除非是研發出一全新的結構，並隨著製程技術的提升而生產出具有超細線路、更為薄型化及材質輕量化的電路板，否則要對發光鍵盤結構作出十分巨大的改變是很困難的，所以在大致結構無法改變時，一般都是在發光鍵盤細部結構作改變以確實減少整體之總厚度，更能滿足發光鍵盤相關產品輕、薄、短、小之設計需求，且組裝工序及元件製造成本亦需加入考慮，始可符合發光鍵盤實際上之運用。 Since the use of the illuminated keyboard has been used for decades, the technology of the illuminated keyboard has been very mature, and in the case that the internal structure of the illuminated keyboard is very simplified, unless a new structure is developed and produced with the improvement of the process technology. A circuit board with ultra-fine lines, thinner and lighter materials, otherwise it is very difficult to make a huge change to the structure of the illuminated keyboard, so when the general structure cannot be changed, it is generally in the detailed structure of the illuminated keyboard. The change is to reduce the overall thickness of the whole, and it can better meet the design requirements of light, thin, short and small light-emitting keyboard related products, and the assembly process and component manufacturing cost also need to be considered, which can meet the practical application of the illuminated keyboard.
惟目前鍵盤設計在有限的空間下將愈來愈趨向於薄型化，使鍵盤內部空間亦趨於窄小，此種背光模組之總厚度為導光板加上發光單元及反光片之堆疊厚度，造成整體厚度將會受到本身結構上之限制而無法更加有效降低，因此便有業者研發出將複數LED晶粒利用印刷製程的方式製作在導電層表面上，並經固化後使其電性連接於導電層上形成一發光主要構層，並將發光層設置於按鍵模組的底板與鍵帽之間，此種層狀結構設計可省略導光板及反光片堆疊厚度，使總厚度相對減少，亦不需在反光片上開設許多可供發光二極體伸入並朝導光板投射光線之通孔，便可簡化整體結構及降低製造之成本，但於實際製造的過程中，由於複數LED晶粒分佈的密度不易控制，造成複數LED晶粒通電產生的光線投射至鍵帽 上之亮度無法保持一致且不均勻，並會產生有光點閃爍或出現星空現象，進而影響到發光鍵盤整體之視覺效果。 However, the current keyboard design will become thinner and thinner in a limited space, and the internal space of the keyboard will also be narrow. The total thickness of the backlight module is the thickness of the light guide plate plus the stacking unit of the light-emitting unit and the reflector. The overall thickness will be limited by its own structure and cannot be effectively reduced. Therefore, some manufacturers have developed a method in which a plurality of LED dies are formed on the surface of a conductive layer by a printing process, and are cured to be electrically connected thereto. A light-emitting main layer is formed on the conductive layer, and the light-emitting layer is disposed between the bottom plate of the button module and the keycap. The layered structure design can omit the thickness of the light guide plate and the reflector stack, so that the total thickness is relatively reduced. There is no need to open a number of through holes in the reflector for the light emitting diode to project into the light guide plate, which simplifies the overall structure and reduces the manufacturing cost, but in the actual manufacturing process, due to the multiple LED crystal distribution The density is not easy to control, causing the light generated by the energization of the plurality of LED dies to be projected onto the keycap The brightness on the top cannot be consistent and uneven, and there will be flashing of light spots or starry sky, which will affect the overall visual effect of the illuminated keyboard.
另外，為了避免因飲料、水、灰塵或污物等經由各個按鍵間之微小空隙進入至鍵盤內部，造成薄膜電路板上佈設之電子元件、線路等運作時可能產生短路、損壞或功能失效等，一般係在鍵盤底部的基板上設置有多個導流孔，並於薄膜電路板表面上塗佈有一防水膠層，即可透過防水膠層防止飲料、水或水氣等液體侵入鍵盤內部或接觸到薄膜電路板，並通過導流孔排出至鍵盤外部，以確保防潑水之功能，惟該防水膠層在長久使用下，便會因液體的侵蝕或膠體材質老化的緣故，依然無法達到全面性的防水效果，導致飲料、水或水氣等液體仍會侵入鍵盤內部，並造成其薄膜電路板上之電子元件、薄膜開關、線路等產生短路或損壞，即為有待從事於此行業者所亟欲重新設計之關鍵所在。 In addition, in order to prevent beverages, water, dust, or dirt from entering the inside of the keyboard through a small gap between the buttons, the electronic components, circuits, and the like disposed on the film circuit board may be short-circuited, damaged, or functionally disabled. Generally, a plurality of flow guiding holes are arranged on the substrate at the bottom of the keyboard, and a waterproof rubber layer is coated on the surface of the thin film circuit board, so that liquid, such as beverage, water or moisture, can be prevented from intruding into the keyboard or contacting through the waterproof adhesive layer. Go to the thin-film circuit board and discharge it to the outside of the keyboard through the diversion hole to ensure the function of water repellent. However, if the waterproof adhesive layer is used for a long time, it will not be comprehensive due to liquid corrosion or aging of the colloidal material. The waterproof effect causes liquids such as beverages, water or moisture to invade the inside of the keyboard and cause short-circuit or damage to electronic components, membrane switches, circuits, etc. on the thin-film circuit board, which is what is to be done by those in the industry. The key to redesigning.
故，新型創作人有鑑於上述習用之問題與缺失，乃搜集相關資料經由多方的評估及考量，並利用從事於此行業之多年研發經驗不斷的試作與修改，始有此種具防水功能之可調校式鍵盤新型誕生。 Therefore, in view of the above-mentioned problems and shortcomings, the new creators have collected and reviewed relevant materials through various assessments and trials, and have used the trial and modification of many years of R&D experience in this industry to have such waterproof functions. A new type of tuning keyboard was born.
本創作之主要目的乃在於軟性電路板之上下二側表面分別設有複數發光元件及控制電路之一脈寬調變控制晶片，並由脈寬調變控制晶片與該些發光元件電性連接，且該控制電路可根據脈寬調變控制晶片控制脈寬調變訊號百分比各別控制該些發光元件之亮度，而軟性電路板上表面結合有一透光隔絕膜，並於軟性電路板下表面設置有按鍵組件之底板，且按鍵組件之鍵帽通過連接組件設置於該底板上，便可藉由透光隔絕膜上 一體成型之凸包分別包覆定位於發光元件外部形成一密封狀態，並與外界的水氣或液體隔絕，以避免進入產品內部產生短路或損壞，藉此可加強防水之效果，並確保軟性電路板正常的運作而延長產品壽命，以及降低整體之厚度使其更為薄型化。 The main purpose of the present invention is to provide a plurality of light-emitting elements and a pulse width modulation control chip respectively on the lower two sides of the flexible circuit board, and the pulse width modulation control chip is electrically connected to the light-emitting elements. And the control circuit can separately control the brightness of the light-emitting elements according to the pulse width modulation control chip control pulse width modulation signal percentage, and the surface of the flexible circuit board is combined with a light-transmissive isolation film and is disposed on the lower surface of the flexible circuit board. The bottom plate of the button assembly is provided, and the key cap of the button component is disposed on the bottom plate through the connecting component, and can be disposed on the transparent insulating film The integrally formed convex hulls are respectively wrapped and positioned on the outside of the illuminating element to form a sealed state, and are isolated from the outside water or liquid to avoid short circuit or damage inside the product, thereby enhancing the waterproof effect and ensuring the soft circuit. The normal operation of the board extends the life of the product and reduces the overall thickness to make it thinner.
本創作之次要目的乃在於該按鍵組件之底板係設置於軟性電路板下表面，並使脈寬調變控制晶片伸入底板之破孔內，所以底板之厚度可節省脈寬調變控制晶片佔用之高度，使軟性電路板只有增加發光元件高度，以巧妙運用整體之上下空間配置，使鍵帽按壓行程範圍內不會受到脈寬調變控制晶片或發光元件干涉，且整體之總厚度減少，當使用者按壓鍵帽下壓彈性元件時，可觸發電路板之開關或薄膜電路板之薄膜開關形成電性導通，並由控制電路根據脈寬調變控制晶片控制脈寬調變訊號百分比以時序開關各別控制對應該鍵帽之發光元件，讓每一鍵帽不致因單位面積內之發光元件分佈的密度不同造成發光亮度無法保持一致，並提供一致的亮度輸出，進而達到提升發光均勻度之效果。 The second purpose of the creation is that the bottom plate of the button assembly is disposed on the lower surface of the flexible circuit board, and the pulse width modulation control chip is inserted into the hole of the bottom plate, so the thickness of the bottom plate can save the pulse width modulation control chip. The height of the occupancy makes the flexible circuit board only increase the height of the light-emitting component, so as to cleverly use the overall upper and lower space configuration, so that the keycap can not be interfered by the pulse width modulation control chip or the light-emitting component within the pressing stroke range, and the overall total thickness is reduced. When the user presses the keycap to press the elastic component, the switch of the circuit board or the membrane switch of the thin film circuit board can be electrically connected, and the control circuit controls the percentage of the pulse width modulation signal according to the pulse width modulation. The timing switches respectively control the light-emitting elements corresponding to the key caps, so that each key cap does not cause the brightness of the light to be consistent due to the different density distribution of the light-emitting elements per unit area, and provides a uniform brightness output, thereby achieving improved uniformity of illumination.
