本发明是有关于一种触控板模块与应用其的电子装置，且特别是有关于一种触控板模块与电子装置。The present invention relates to a touch panel module and an electronic device using the same, and in particular to a touch panel module and an electronic device.
背景技术Background technique
近年来，随着科技产业日益发达，电子装置例如笔记本电脑(notebook computer,NB)、平板电脑(tablet PC)与智能手机(smart phone)等产品已频繁地出现在日常生活中。电子装置的型态与使用功能越来越多元，便利性与实用性让这些电子装置更为普及，可针对不同用途使用。In recent years, with the development of the technology industry, electronic devices such as notebook computers (NB), tablet PCs (tablet PCs) and smart phones (smart phones) have frequently appeared in daily life. The types and functions of electronic devices are becoming more and more diverse. The convenience and practicality make these electronic devices more popular and can be used for different purposes.
电子装置，如笔记本电脑，一般会配置键盘(keyboard)组件与触控板(touch pad)模块以作为电子装置的输入接口。触控板模块的触控板通常对应于开关，使得使用者能经由触碰位于电子装置外部的触控板而触发位于电子装置内部的开关。然而，在电子装置薄型化的过程中，触控板与按键的整合设计虽可节省电子装置内部的配置空间，并提供较大的触控区域供使用者操作，却也伴随着触控板与开关之间的按压行程过短，而造成使用者操作时的按压感不明确。因此，如何在有限空间内产生较大的按压行程并且降低触控板作动时所产生的噪音，实为目前亟待解决的问题。Electronic devices, such as notebook computers, are generally configured with a keyboard component and a touch pad module as input interfaces of the electronic device. The touchpad of the touchpad module usually corresponds to a switch, so that a user can trigger a switch inside the electronic device by touching the touchpad outside the electronic device. However, in the process of thinning electronic devices, although the integrated design of the touchpad and buttons can save the configuration space inside the electronic device and provide a larger touch area for the user to operate, it is also accompanied by the touchpad and buttons. The pressing stroke between the switches is too short, resulting in unclear pressing feeling when the user operates. Therefore, how to generate a larger pressing stroke in a limited space and reduce the noise generated when the touch panel is actuated is an urgent problem to be solved at present.

本发明的一实施例提供一种电子装置，包括壳体、触控板、电路板以及触发件。壳体具有开口。触控板配置于壳体，且触控板的触控面从开口暴露出壳体。电路板配置于壳体内且具有凹陷区。触发件配置于电路板上。触发件覆盖于凹陷区上方且位于触控板与电路板之间，其中当触发件受外力产生变形时，至少部分触发件位于凹陷区内。An embodiment of the invention provides an electronic device, including a housing, a touch panel, a circuit board, and a trigger. The housing has an opening. The touch pad is configured on the casing, and the touch surface of the touch pad is exposed from the casing through the opening.

The trigger part is covered above the recessed area and located between the touch panel and the circuit board, wherein when the trigger part is deformed by external force, at least part of the trigger part is located in the recessed area.
基于上述，在本发明的上述实施例中，触发件通过覆盖于电路板的凹陷区上方，以使触发件在受力变形的情况下，部分的触发件会位于凹陷区内。据此，大幅提升了触发件的按压行程而让使用者在操作触控板时具有较佳的按压感，且凹陷区亦有效降低触控板作动时所产生的噪音。Based on the above, in the above embodiments of the present invention, the trigger part covers the recessed area of the circuit board, so that when the trigger part is deformed by force, part of the trigger part will be located in the recessed area. Accordingly, the pressing stroke of the trigger member is greatly increased, so that the user has a better pressing feeling when operating the touch panel, and the recessed area also effectively reduces the noise generated when the touch panel is operated.

图2是图1的触控板模块的局部放大图。图3A是图1的触控板模块的局部剖面图。图3B是图3A的电路板的示意图。图3C是图3A的触控板模块受外力时的局部剖面图。请参考图2以及图3A，在本实施例中，触控板模块100A包括电路板110以及触发件120。电路板110具有凹陷区111。触发件120配置于电路板110上，且覆盖于凹陷区111上方，而使触发件120位于触控板150与电路板110之间。一般而言，电路板110可以是硬式印刷电路板或金属芯印刷电路板，其中凹陷区111例如是通过蚀刻或钻孔等工艺而形成于电路板110上，因而使电路板110的第一表面S1与位于凹陷区111的第二表面S2之间存在高度落差。如图3B所示，凹陷区111的底面例如是圆形，但在其他未绘示的实施例中，凹陷区111亦可以是椭圆形或多边形，本发明在此并不加以限制。FIG. 2 is a partially enlarged view of the touch panel module in FIG. 1 . FIG. 3A is a partial cross-sectional view of the touch panel module of FIG. 1 . FIG. 3B is a schematic diagram of the circuit board of FIG. 3A . FIG. 3C is a partial cross-sectional view of the touch panel module in FIG. 3A when an external force is applied. Please refer to FIG. 2 and FIG. 3A , in this embodiment, the touch panel module 100A includes a circuit board 110 and a trigger 120 . The circuit board 110 has a recessed area 111 . The trigger element 120 is disposed on the circuit board 110 and covers the recessed area 111 , so that the trigger element 120 is located between the touch panel 150 and the circuit board 110 . Generally speaking, the circuit board 110 can be a rigid printed circuit board or a metal core printed circuit board, wherein the recessed area 111 is formed on the circuit board 110 by, for example, etching or drilling, so that the first surface of the circuit board 110 There is a height difference between S1 and the second surface S2 located in the recessed area 111 . As shown in FIG. 3B , the bottom surface of the recessed area 111 is, for example, circular, but in other unillustrated embodiments, the recessed area 111 may also be oval or polygonal, and the present invention is not limited thereto.
请参考图3A以及图3B，在本实施例中，电路板110还包括位于第一表面S1的接地区112以及位于第二表面S2的触压作动区113，其中接地区112环绕凹陷区111但彼此分离。一般而言，接地区112以及触压作动区113例如是通过电镀、网印印刷或喷涂印刷等方法而形成于电路板110上的电路图案。触发件120例如是圆形顶(dome-shaped)的金属簧片且具有弹性。触发件120的周缘抵接于接地区112，而使触发件120立于电路板110的第一表面S1上，且触发件120的顶部与电路板110之间存在间隙D1。Please refer to FIG. 3A and FIG. 3B. In this embodiment, the circuit board 110 further includes a grounding area 112 located on the first surface S1 and a contact pressure action area 113 located on the second surface S2, wherein the grounding area 112 surrounds the recessed area 111. but separated from each other. Generally speaking, the grounding area 112 and the touch-press action area 113 are circuit patterns formed on the circuit board 110 by methods such as electroplating, screen printing, or spray printing. The trigger member 120 is, for example, a dome-shaped metal reed with elasticity. The peripheral edge of the trigger 120 abuts against the grounding area 112 , so that the trigger 120 stands on the first surface S1 of the circuit board 110 , and there is a gap D1 between the top of the trigger 120 and the circuit board 110 .
具体而言，本实施例的触发件120具有朝向触控板150的凸起部121，如图3C所示，当使用者按压触控面151时，触控板150以外力F抵接于触发件120上，进而驱动触控板150向下作动而抵接凸起部121，使得触发件120承受外力F产生变形，其中至少部分的触发件120因变形而移入凹陷区111内，并进一步与凹陷区111内的触压作动区113相互抵接，因而使触压作动区113与接地区112经由触发件120相互电性连接而产生操作信号。Specifically, the trigger member 120 of this embodiment has a raised portion 121 facing the touch panel 150. As shown in FIG. 120, and then drive the touch panel 150 to move downward to abut against the raised portion 121, so that the trigger 120 is deformed under the external force F, wherein at least part of the trigger 120 moves into the recessed area 111 due to the deformation, and further It abuts against the touch-pressure actuation area 113 in the recessed area 111 , so that the touch-pressure actuation area 113 and the grounding area 112 are electrically connected to each other via the trigger 120 to generate an operation signal.
在本实施例中，触发件120承受外力F时具有大于间隙D1的最大可变形量D2，而正由于电路板110上存在凹陷区111足以让产生该最大可变形量D2的部分触发件120容置其中，因此相较于现有技术仅能让触发件接触至第一表面的变形状态，本实施例的电路板110提供触发件120较大的按压行程，即让触发件120产生最大可变形量D2的弹性变形而得以触压至位于第二表面S2的触压作动区113，而使使用者于操控触控板模块100A时具有较佳且明确的按压感。In this embodiment, when the trigger member 120 is subjected to the external force F, it has a maximum deformable amount D2 greater than the gap D1, and because the recessed area 111 on the circuit board 110 is sufficient to accommodate the part of the trigger member 120 that produces the maximum deformable amount D2 Therefore, compared with the deformation state in which the trigger member can only touch the first surface in the prior art, the circuit board 110 of this embodiment provides a larger pressing stroke of the trigger member 120, that is, the trigger member 120 can be deformed to the maximum The elastic deformation of the amount D2 can be pressed to the touch-press action area 113 on the second surface S2, so that the user has a better and clear press feeling when manipulating the touch panel module 100A.
图4A是本发明另一实施例的触控板模块的局部剖面图。图4B是图4A的电路板的示意图。请参考图4A与图4B，图4A的触控板模块100B与图3A的触控板模块100A相似，其不同之处在于：本实施例的触控板模块100B的电路板110还具有通气流道114，连通于凹陷区111与电路板110的侧表面116之间。一般而言，通气流道114例如通过蚀刻或钻铣等工艺与凹陷区111同时形成于电路板110上。通气流道114用以提供凹陷区111与电路板110外的环境连通的管道，以避免触发件120与凹陷区111构成密封空间而让触发件120因按压变形所产生的音波在此密闭空间中不断反射。换句话说，通气流道114能有效地将触发件120变形所产生的音波有效地传导出电路板110外，从而降低了触发件120作动时的噪音。FIG. 4A is a partial cross-sectional view of a touch panel module according to another embodiment of the present invention. FIG. 4B is a schematic diagram of the circuit board of FIG. 4A. Please refer to FIG. 4A and FIG. 4B, the touch panel module 100B of FIG. 4A is similar to the touch panel module 100A of FIG. The channel 114 communicates between the recessed area 111 and the side surface 116 of the circuit board 110 . Generally speaking, the air passage 114 is formed on the circuit board 110 simultaneously with the recessed area 111 , for example, by etching, drilling and milling. The ventilation flow channel 114 is used to provide a channel for communication between the recessed area 111 and the environment outside the circuit board 110, so as to prevent the trigger member 120 and the recessed area 111 from forming a sealed space and allowing the sound waves generated by the trigger member 120 to be deformed by pressing in the sealed space. Constant reflection. In other words, the air passage 114 can effectively transmit the sound wave generated by the deformation of the trigger member 120 out of the circuit board 110 , thereby reducing the noise when the trigger member 120 is actuated.
图5A是本发明又一实施例的触控板模块的局部剖面图。图5B是图5A的电路板的示意图。图5C是图5A的触控板模块受外力时的局部剖面图。请参考图5A与图5B，图5A的触控板模块100C与上述实施例的触控板模块的不同处在于：在本实施例的触控板模块100C中，位于电路板110上的凹陷区111a是贯孔，其例如通过机械钻孔或雷射钻孔形成于电路板110上。另一方面，接地区112与触压作动区113位于电路板110的同一平面(即第一表面S1)上，更详细而言，触压作动区113配置于接地区112与凹陷区111a之间，且触压作动区113环绕凹陷区111a周围而形成同心配置的图案。5A is a partial cross-sectional view of a touch panel module according to another embodiment of the present invention. FIG. 5B is a schematic diagram of the circuit board of FIG. 5A. FIG. 5C is a partial cross-sectional view of the touch panel module in FIG. 5A when an external force is applied. Please refer to FIG. 5A and FIG. 5B , the difference between the touch panel module 100C of FIG. 5A and the touch panel module of the above-mentioned embodiment is that in the touch panel module 100C of this embodiment, the recessed area located on the circuit board 110 111a is a through hole, which is formed on the circuit board 110 by mechanical drilling or laser drilling, for example. On the other hand, the grounding area 112 and the touch-press action area 113 are located on the same plane (namely the first surface S1) of the circuit board 110. More specifically, the touch-press action area 113 is disposed between the ground area 112 and the recessed area 111a , and the touch-pressed actuating area 113 surrounds the recessed area 111a to form a concentric pattern.
如图5C所示，当使用者按压触控面151时，触控板150以外力F抵接于触发件120上，以通过触控板150向下作动而抵接凸起部121，使得触发件120承受外力F产生变形，且让至少部分的触发件120因变形而移入凹陷区111a内，并进一步与环绕凹陷区111a周围的触压作动区113相互抵接，因而使触压作动区113与接地区112经由触发件120相互电性连接而产生操作信号。也就是说，本实施例的触发件120承受外力F时具有大于间隙D1的最大可变形量D2，因而使使用者在操控触控板模块100C时具有较佳且明确的按压感。另一方面，设计为贯孔的凹陷区111a可避免触发件120与凹陷区111a构成密封空间，从而有效降低触发件120作动时的噪音。As shown in FIG. 5C , when the user presses the touch surface 151, the touchpad 150 abuts against the trigger member 120 with an external force F, so that the touchpad 150 moves downward to abut against the raised portion 121, so that The trigger piece 120 is deformed under the external force F, and at least part of the trigger piece 120 moves into the recessed area 111a due to the deformation, and further abuts against the contact pressure action area 113 surrounding the recess area 111a, thus making the contact pressure action The moving area 113 and the grounding area 112 are electrically connected to each other via the trigger 120 to generate an operation signal. That is to say, the trigger member 120 of this embodiment has a maximum deformable amount D2 greater than the gap D1 when subjected to the external force F, so that the user has a better and clear pressing feeling when manipulating the touch panel module 100C. On the other hand, the recessed area 111a designed as a through hole can prevent the trigger member 120 from forming a sealed space with the recessed area 111a, thereby effectively reducing the noise when the trigger member 120 operates.
图6A是本发明又一实施例的触控板模块的局部剖面图。图6B是图6A的电路板的示意图。图6C是图6A的触控板模块受外力时的局部剖面图。请参考图6A与图6B，本实施例的触控板模块100D与上述实施例的触控板模块的不同处在于：本实施例的触控板模块100D的电路板110具有贯孔115，更具体而言，在本实施例中，贯孔115例如是位于凹陷区111内，且触压作动区113环绕贯孔115周围。一般而言，贯孔115例如通过机械钻孔或雷射钻孔形成于电路板110上。FIG. 6A is a partial cross-sectional view of a touch panel module according to another embodiment of the present invention. FIG. 6B is a schematic diagram of the circuit board of FIG. 6A. FIG. 6C is a partial cross-sectional view of the touch panel module in FIG. 6A when an external force is applied. Please refer to FIG. 6A and FIG. 6B. The difference between the touch panel module 100D of this embodiment and the touch panel module of the above-mentioned embodiments is that the circuit board 110 of the touch panel module 100D of this embodiment has a through hole 115, and Specifically, in this embodiment, the through hole 115 is, for example, located in the recessed area 111 , and the touch-press actuation area 113 surrounds the through hole 115 . Generally speaking, the through hole 115 is formed on the circuit board 110 by, for example, mechanical drilling or laser drilling.
如图6C所示，当使用者按压触控面151时，触控板150以外力F抵接于触发件120上，以通过触控板150向下作动而抵接凸起部121，使得触发件120承受外力F产生变形，且让至少部分的触发件120因变形而移入凹陷区111内并且与凹陷区111内的触压作动区113相互抵接，因而使触压作动区113与接地区112经由触发件120相互电性连接而产生操作信号。具体而言，本实施例的触发件120承受外力F时具有大于间隙D1的最大可变形量D2，且触发件120产生最大可变形量D2的弹性变形可延伸至贯孔115内，而使使用者在操控触控板模块100D时具有较佳且明确的按压感。另一方面，贯孔115可避免触发件120与凹陷区111构成密封空间，从而降低了触发件120作动时的噪音。As shown in FIG. 6C , when the user presses the touch surface 151, the touchpad 150 abuts against the trigger member 120 with an external force F, so that the touchpad 150 moves downward to abut against the raised portion 121, so that The trigger member 120 is deformed under the external force F, and at least part of the trigger member 120 is deformed to move into the recessed area 111 and abut against the contact pressure action area 113 in the recess area 111, thus making the contact pressure action area 113 It is electrically connected with the grounding area 112 via the trigger 120 to generate an operation signal. Specifically, the trigger member 120 of this embodiment has a maximum deformable amount D2 greater than the gap D1 when subjected to an external force F, and the elastic deformation of the trigger member 120 that produces the maximum deformable amount D2 can extend into the through hole 115, so that the use The latter has a better and clear pressing feeling when manipulating the touchpad module 100D. On the other hand, the through hole 115 can prevent the trigger member 120 from forming a sealed space with the recessed area 111 , thereby reducing the noise when the trigger member 120 operates.
综上所述，本发明的触控板模块适于装设于电子装置内，其中触控模块包括电路板以及触发件，触发件抵接于电路板上的接地区并且覆盖于电路板的凹陷区上方。当触发件受力变形时，至少部分的触发件会位于凹陷区内，且触发件进一步与凹陷区内的触发作动区或环绕凹陷区的触发作动区相互抵接，用以电性连接至电路板而产生一操作信号。换言之，触发件的可变形量大于触发件与电路板之间的一间隙，而大幅提升了触发件的按压行程而让使用者在操作触控板时具有较佳的按压感。此外，电路板上更具有通气流道或贯孔，可避免触发件与凹陷区构成一密封空间，从而有效降低触控板作动时所产生的噪音。In summary, the touch panel module of the present invention is suitable for being installed in an electronic device, wherein the touch module includes a circuit board and a trigger, and the trigger abuts against the grounding area on the circuit board and covers the depression of the circuit board area above. When the trigger is deformed by force, at least part of the trigger will be located in the recessed area, and the trigger will further abut against the trigger action area in the recess area or the trigger action area surrounding the recess area for electrical connection to the circuit board to generate an operation signal. In other words, the deformable amount of the trigger member is larger than the gap between the trigger member and the circuit board, so that the pressing stroke of the trigger member is greatly increased and the user has a better pressing feeling when operating the touch panel. In addition, the circuit board is further provided with air passages or through holes, which can prevent the trigger member and the recessed area from forming a sealed space, thereby effectively reducing the noise generated when the touch panel is operated.
