本发明的键盘组件请同时参考图2A及图2B，其中，图2A是本发明键盘组件20的分解立体示意图，图2B是本发明键盘组件20的剖面图。可一并参阅图1A所绘示的现有的手持式电子装置，本发明的键盘组件20较佳是应用于一手持式电子装置，下文将配合附图详述本发明的键盘组件20的要件组成。须说明的是，为清楚揭露本发明的结构，本申请附图以略为夸大的方式绘制，用于说明而非限定本发明，本申请所请求的范围，以所附的权利要求限定的范围为准。Please refer to FIG. 2A and FIG. 2B for the keyboard assembly of the present invention, wherein FIG. 2A is an exploded perspective view of the keyboard assembly 20 of the present invention, and FIG. 2B is a cross-sectional view of the keyboard assembly 20 of the present invention. The existing handheld electronic device shown in FIG. 1A can also be referred to. The keyboard assembly 20 of the present invention is preferably applied to a handheld electronic device. The key elements of the keyboard assembly 20 of the present invention will be described in detail below with reference to the accompanying drawings. composition. It should be noted that, in order to clearly disclose the structure of the present invention, the accompanying drawings of this application are drawn in a slightly exaggerated manner, and are used to illustrate rather than limit the present invention. The scope of the application is defined by the appended claims. allow.
如图所示，本发明的键盘组件20主要包含一电路板28、多个金属圆顶结构(metal dome structure)26、一固定片25、一金属网24以及一按压辅助片23。其中，电路板28具有一导电层，形成于电路板28的表面上，该导电层包含多个导电接点281以及分别与导电接点281电性连接的多个导电线路282。而这些金属圆顶结构26分别设置于对应的导电接点281上，当该金属圆顶结构26受到压掣而与导电接点281成电性接触，将可产生一输出信号。As shown in the figure, the keyboard assembly 20 of the present invention mainly includes a circuit board 28 , a plurality of metal dome structures 26 , a fixing piece 25 , a metal mesh 24 and a pressing auxiliary piece 23 . Wherein, the circuit board 28 has a conductive layer formed on the surface of the circuit board 28 , the conductive layer includes a plurality of conductive contacts 281 and a plurality of conductive circuits 282 electrically connected to the conductive contacts 281 . The metal dome structures 26 are respectively disposed on the corresponding conductive contacts 281 , and when the metal dome structures 26 are pressed and come into electrical contact with the conductive contacts 281 , an output signal can be generated.
该固定片25较佳是由绝缘材料制成，并整体覆盖于这些金属圆顶结构26及电路板28上，其主要功能在于贴附及定位这些金属圆顶结构26。该金属网24设置于固定片25的局部区域上，明确而言，金属网24设置于相对于这些金属圆顶结构26之外的区域。在实际作法上，金属网24可为预先制成，并对应这些金属圆顶结构26位置处形成穿孔，再铺设至固定片25上；本发明的较佳实施态样是以特殊印刷工艺例如压模成型技术(compression molding)，直接将金属材料直接印刷于该固定片25的表面上，同样地，制作工序中亦回避对应这些金属圆顶结构26的位置。如同前述，金属网24的设置目的在于防止信号传递过程中产生的电磁干扰。相对于现有的键盘组件10的设计，本发明不需要预留空间以配置该金属板140，故可缩小键盘组件20的体积与厚度，亦可降低生产成本。The fixing sheet 25 is preferably made of insulating material, and covers the metal dome structures 26 and the circuit board 28 as a whole, and its main function is to attach and position the metal dome structures 26 . The metal mesh 24 is disposed on a local area of the fixing piece 25 , specifically, the metal mesh 24 is disposed on a region outside the metal dome structures 26 . In actual practice, the metal mesh 24 can be prefabricated, and form perforations corresponding to the positions of these metal dome structures 26, and then lay on the fixed sheet 25; Compression molding technology directly prints the metal material on the surface of the fixing piece 25. Similarly, the positions corresponding to the metal dome structures 26 are also avoided in the manufacturing process. As mentioned above, the purpose of setting the metal mesh 24 is to prevent electromagnetic interference generated during signal transmission. Compared with the design of the existing keyboard assembly 10 , the present invention does not need to reserve a space for disposing the metal plate 140 , so the volume and thickness of the keyboard assembly 20 can be reduced, and the production cost can also be reduced.
按压辅助片23覆盖于金属网24及固定片25上，于本发明中，按压辅助片23具有多个圆顶突出结构231，其分布分别对应于这些金属圆顶结构26的位置。各圆顶突出结构231的顶端处形成一柱塞体232，该柱塞体232相对于底部的金属圆顶结构26，而自圆顶突出结构231向上延伸。按压辅助片23的圆顶突出结构231用以提升使用者的按压手感，由于金属网24的配置设计是回避这些金属圆顶结构26及圆顶突出结构231，故当使用者施力按压按键时，圆顶突出结构231将配合着固定片25，直接将压力向下传递至金属圆顶结构26。The pressing auxiliary sheet 23 covers the metal mesh 24 and the fixing sheet 25 . In the present invention, the pressing auxiliary sheet 23 has a plurality of dome protrusion structures 231 , and the distribution thereof corresponds to the positions of the metal dome structures 26 . A plunger body 232 is formed at the top of each dome protrusion structure 231 , and the plunger body 232 extends upward from the dome protrusion structure 231 relative to the metal dome structure 26 at the bottom. The dome protruding structure 231 of the pressing auxiliary sheet 23 is used to enhance the user's pressing feel. Since the configuration design of the metal mesh 24 is to avoid these metal dome structures 26 and the dome protruding structure 231, when the user applies force to press the key , the dome protruding structure 231 will cooperate with the fixing piece 25 to directly transmit the pressure downward to the metal dome structure 26 .
于一较佳实施例中，本发明的键盘组件20还可包含一支撑层27，设置于固定片25与电路板28之间，且于这些金属圆顶结构26之外的区域。详言之，支撑层27可为一膜片结构，并形成有多个对应金属圆顶结构26位置的穿孔，该支撑层27环绕该金属圆顶结构26的周围区域，以减缓固定片25因覆盖金属圆顶结构26所形成的局部高度差，若支撑层27紧靠金属圆顶结构26，甚至还可以协助固定金属圆顶结构26的位置。较佳地，该支撑层27是以绝缘材料所制成。In a preferred embodiment, the keyboard assembly 20 of the present invention may further include a support layer 27 disposed between the fixing piece 25 and the circuit board 28 and outside the metal dome structures 26 . In detail, the support layer 27 can be a diaphragm structure, and is formed with a plurality of perforations corresponding to the position of the metal dome structure 26. The local height difference formed by covering the metal dome structure 26 can even help to fix the position of the metal dome structure 26 if the supporting layer 27 is close to the metal dome structure 26 . Preferably, the supporting layer 27 is made of insulating material.
于本发明中，该固定片25较佳是一迈拉胶片(Mylar film)；而金属网24较佳是一银网。以上材质是教示本发明的较佳实施方式，所属领域具有通常知识者，应可能寻找其它替代的材料，同样可达到本发明的目的，故非用以限定本发明。In the present invention, the fixing sheet 25 is preferably a Mylar film; and the metal mesh 24 is preferably a silver mesh. The above materials are the preferred implementation modes of the present invention. Those with ordinary knowledge in the field should be able to find other alternative materials, which can also achieve the purpose of the present invention, so they are not intended to limit the present invention.
根据前述键盘组件20的结构，其应用于一手持式电子装置时，可还包含一导光膜22及一按键本体21。其中，按键本体21上具有多个按键211，其分别对应于这些金属圆顶片26或导电接点281的配置。而导光膜22设置于按键本体21与按压辅助片23之间且于按压辅助片23上，通过此配置，柱塞体232将顶掣于导光膜22的底面。导光膜22的设计目的在于当键盘组件20设计为可发光时，导光膜22将提升其透光效果，增加产品的实用性。According to the aforementioned structure of the keyboard assembly 20 , when it is applied to a handheld electronic device, it may further include a light guide film 22 and a key body 21 . Wherein, the key body 21 has a plurality of keys 211 corresponding to the configurations of the metal domes 26 or the conductive contacts 281 respectively. The light guide film 22 is disposed between the key body 21 and the pressing auxiliary sheet 23 and on the pressing auxiliary sheet 23 . Through this configuration, the plunger body 232 will push against the bottom surface of the light guiding film 22 . The design purpose of the light guide film 22 is that when the keyboard assembly 20 is designed to emit light, the light guide film 22 will enhance its light transmission effect and increase the practicability of the product.
于操作时，当按键本体21上的按键211接受来自使用者的按压，将转而对按压辅助片23上的柱塞体232施加压力，进而通过圆顶突出结构231压掣金属圆顶结构26。当金属圆顶结构26受到压掣而与其对应的导电接点281接触形成导通，将产生一输出信号，并通过这些导电线路282传递至一处理器(图未示出)。该手持式电子装置可因应该输出信号，作出相应的动作。During operation, when the button 211 on the button body 21 receives the pressure from the user, it will in turn apply pressure to the plunger body 232 on the pressing auxiliary piece 23, and then press the metal dome structure 26 through the dome protrusion structure 231 . When the metal dome structure 26 is pressed and contacts with its corresponding conductive contact 281 to form conduction, an output signal will be generated and transmitted to a processor (not shown in the figure) through these conductive lines 282 . The handheld electronic device can take corresponding actions in response to the output signal.
综上所述，相较于现有的键盘组件10，本发明的键盘组件20省却了软性电路板、连接排线、连接器及金属板等组件的设置，而改将现有的软性电路板的线路，直接整合至电路板上，并以金属网取代金属板。由此，本发明键盘组件的体积及重量，将大幅减少，而组装成本及时间也将有效降低，可显著提高产品竞争能力。To sum up, compared with the existing keyboard assembly 10, the keyboard assembly 20 of the present invention saves the setting of components such as flexible circuit boards, connecting cables, connectors, and metal plates, and replaces the existing flexible circuit boards. The wiring of the circuit board is directly integrated into the circuit board, and the metal plate is replaced by a metal mesh. Therefore, the volume and weight of the keyboard assembly of the present invention will be greatly reduced, and the assembly cost and time will also be effectively reduced, which can significantly improve product competitiveness.
