本实用新型是提供一种键盘背光模块周围发光结构，尤指背光模块的遮光层为利用透明薄膜材质可透光的特性将导光板入射至遮光层的光线侧向穿出，使背光模块周围处形成有发光区域可照亮电子装置上对应的端口，以方便插接使用。The utility model provides a light-emitting structure around a keyboard backlight module, especially the light-shielding layer of the backlight module. The light that is incident on the light-shielding layer from the light guide plate passes through sideways by utilizing the light-transmitting characteristics of the transparent film material, so that the surrounding areas of the backlight module The light-emitting area is formed to illuminate the corresponding port on the electronic device, so as to facilitate plug-in use.
背景技术Background technique
现今电子科技与信息产业的快速发展，使各种电子产品皆朝向轻、薄、短、小且功能强大的趋势发展，如计算机、笔记本电脑、行动上网装置(MID)、智能型手机、平板计算机等，已成为现代人在日常生活或工作上所不可或缺的电子产品，而用户与电子产品之间大多是使用鼠标、键盘等输入设备来沟通，其中又以键盘最为方便作文字、数字或指令的输入操作，并提升实用的功能。The rapid development of today's electronic technology and information industry has led to the development of various electronic products towards the trend of light, thin, short, small and powerful functions, such as computers, notebook computers, mobile Internet devices (MID), smart phones, tablet computers etc., have become indispensable electronic products in the daily life or work of modern people, and most of the users and electronic products use mouse, keyboard and other input devices to communicate, among which the keyboard is the most convenient to write text, numbers or The input operation of the command, and enhance the practical function.
再者，为了在光线不足的环境下能使人眼清楚的看到每个按键上的符号，便有业者在键盘中导入导光板及光源技术，并发展出具背光模块的背光键盘，使背光模块所产生的光线可投射到每个键帽的背面处形成背光效果，让使用者可以清楚看到键帽上的符号，以方便操作使用，而目前市面上的背光键盘包括有按键模块及背光模块，其中该背光模块为具有一导光板，并于导光板上方处设有具软性电路板及发光二极管的发光单元，且该发光单元为朝导光板投射光线使导光板均匀的发光，又导光板下方处为设有可将导光板下表面所射出的光线反射回导光板上的反光片，且导光板上表面设有对应于按键模块处的遮光片，便可将导光板所射出的光线穿过遮光片的透光部入射至按键模块上形成背光。Furthermore, in order to enable the human eye to clearly see the symbols on each key in an environment with insufficient light, some operators have introduced light guide plate and light source technology into the keyboard, and developed a backlit keyboard with a backlight module, so that the backlight module The generated light can be projected to the back of each keycap to form a backlight effect, so that users can clearly see the symbols on the keycaps for easy operation and use. Currently, backlit keyboards on the market include a key module and a backlight module , wherein the backlight module has a light guide plate, and a light-emitting unit with a flexible circuit board and a light-emitting diode is arranged above the light guide plate, and the light-emitting unit projects light toward the light guide plate so that the light guide plate emits light uniformly, and guides Below the light plate is a reflective sheet that can reflect the light emitted from the lower surface of the light guide plate back to the light guide plate, and the upper surface of the light guide plate is provided with a light-shielding sheet corresponding to the button module, so that the light emitted by the light guide plate can be reflected. The light-transmitting portion passing through the light-shielding sheet is incident on the key module to form a backlight.
然而，请参阅如图3所示，是为现有背光模块的局部剖面图，该背光模块A的导光板A1下方处为设有一反射片A2，并于导光板A1上方处设有遮光片A3，且遮光片A3的上下二侧表面处分别形成上水胶层A31及下水胶层A32，而遮光片A3的上水胶层A31为黏贴于按键模块B的底板B1上，并由下水胶层A32黏贴于导光板A1及反射片A2向上包覆导光板A1周围处的表面上结合成为一体。However, please refer to FIG. 3, which is a partial cross-sectional view of an existing backlight module. A reflective sheet A2 is provided below the light guide plate A1 of the backlight module A, and a light-shielding sheet A3 is provided above the light guide plate A1. , and the upper and lower adhesive layers A31 and lower adhesive layers A32 are respectively formed on the upper and lower surfaces of the light shielding sheet A3, and the upper adhesive layer A31 of the optical shielding sheet A3 is pasted on the bottom plate B1 of the button module B, and is formed by the lower adhesive The layer A32 is pasted on the surface of the light guide plate A1 and the reflective sheet A2 upwardly wrapping the periphery of the light guide plate A1 and combined into one body.
惟，一般的背光模块A是利用反射片A2向上包覆于导光板A1周围处，由于反射片A2为白色不透明的材质，可使导光板A1周边处溢出的光线反射形成向上的光束以阻挡导光板A1的光线从背光模块A周围处射出，其虽可避免光源投射出的光线从导光板A1周围处漏出而发生漏光现象，但因电子装置(如笔记本电脑)上时，通常会在壳体周围开口处的端口上形成有多个发光区域，让用户在较为昏暗或光线不足的场所或环境中仍可方便进行插接，此种反射片A2阻挡导光板A1的光线从背光模块A周围处射出的结构设计，便无法照亮壳体开口处对应的端口或其它需要发光的区域，以致壳体内部需要另外设置光源，便会影响到背光模块A或其它构件整体空间配置，所以要如何有效利用背光模块A的光源照亮端口或其它发光区域，以提升空间设计上的弹性，即为从事于此行业者所亟欲重新设计的关键所在。However, the general backlight module A uses the reflective sheet A2 to wrap upwards around the light guide plate A1. Since the reflective sheet A2 is made of white and opaque material, the light overflowing from the periphery of the light guide plate A1 can be reflected to form an upward beam to block the light guide plate A1. The light from the light plate A1 is emitted from the surroundings of the backlight module A. Although it can prevent the light projected from the light source from leaking from the surroundings of the light guide plate A1 and cause light leakage, but when it is installed on an electronic device (such as a notebook computer), it will usually be in the casing. There are multiple light-emitting areas formed on the ports at the surrounding openings, so that users can still conveniently insert and connect in places or environments that are relatively dim or insufficiently lit. The structural design of the injection cannot illuminate the corresponding port at the opening of the housing or other areas that need to be illuminated, so that an additional light source needs to be installed inside the housing, which will affect the overall spatial configuration of the backlight module A or other components, so how to effectively Utilizing the light source of the backlight module A to illuminate ports or other light-emitting areas to improve the flexibility of space design is the key point for those engaged in this industry to redesign.
故，新型创作人有鉴于上述现有的问题与缺点，乃搜集相关资料经由多方评估及考虑，并利用从事于此行业的多年研发经验不断试作与修改，始设计出此种键盘背光模块周围发光结构新型诞生。Therefore, in view of the above-mentioned existing problems and shortcomings, the creators of the new design began to design this kind of keyboard backlight module after collecting relevant information, evaluating and considering it in many ways, and using years of research and development experience in this industry to continuously try and modify it. A new type of light-emitting structure is born.

然而，上述遮光层13的定位部133与反射层12之间为利用涂布方式形成有胶层134，便可将反射层12的定位部133利用胶层134予以黏贴结合于反射层12表面上形成一平整状，使遮光层13内部与反射层12之间形成有可供导光板11定位的容置空间10，且遮光层13厚度为可小于或等于反射层12的厚度；另，导光板11、光源的软性电路板、反射层12、遮光层13表面上亦可依实际需求或结构设计不同进一步分别相对设有多个破孔、通孔或透光区域等，以利于背光模块1与背光键盘的其它构件进行组装或固定使用。However, an adhesive layer 134 is formed between the positioning portion 133 of the light-shielding layer 13 and the reflective layer 12 by coating, so that the positioning portion 133 of the reflective layer 12 can be bonded to the surface of the reflective layer 12 by using the adhesive layer 134 A flat shape is formed on the upper surface, so that an accommodating space 10 for the positioning of the light guide plate 11 is formed between the inside of the light shielding layer 13 and the reflective layer 12, and the thickness of the light shielding layer 13 can be less than or equal to the thickness of the reflective layer 12; The surface of the light board 11, the flexible circuit board of the light source, the reflective layer 12, and the light-shielding layer 13 can also be further provided with a plurality of perforations, through holes, or light-transmitting areas, etc., to facilitate the backlight module. 1 Assemble or fix with other components of the backlit keyboard.

The accommodating space 10 for the light-shielding layer 13 to cover the outside of the light guide plate 11 is formed between the inside of the light-shielding layer 13 and the reflective layer 12.
