当触控组件100的任意位置受到按压时,触控组件100受力下移,第一弹性件220和第二弹性件230发生弹性形变,该固定平台240上的触点241接触并触发触控组件100上的行程开关101。
具体地,触控组件100可以为板状结构,便于为用户提供按压界面。该触控组件100可包括:电路板120。该触控组件100所在的触控板10装配于电子设备之后,电路板120可设置于盖板110的下表面,用户通过按压于盖板110从而按压于电路板120。或者,在一些实施方式中,触控组件100可直接包括:盖板110和电路板120,该触控组件100所在的触控板10可直接装配于电子设备,而不再需要额外的盖板。可选地,如图2和图3所示,盖板110和电路板120之间可以通过连接件,例如胶层111相互连接。
盖板110位于整个触控板10的外表面,为大致平面的刚性材料片,其上表面配置为在触控板10被操作时接触一个或多个用户对象,例如,手指、触笔。因此,用户可以通过使用上述一个或多个用户对象点击、滑动或按压或以其他方式向盖板110的表面施加力来提供输入。
需要说明的是,为了便于描述,在本申请中,“上”、“下”分别指的是朝向用户的方向以及背离用户的方向,而不是绝对的“重力反方向”和“重力方向”。因此,盖板110的上表面即为朝向用户的表面,反之,盖板110的下表面即为背离用户的表面。类似于盖板110,在下文中,触控板10的其它部件的“上”、“下”方向也可理解为朝向用户的方向以及背离用户的方向。
盖板110材料为刚性材料,具体地可以为玻璃,聚碳酸酯(PC)片材,陶瓷片材,麦拉(Mylar)片材等刚性物体。盖板110的顶表面可以是光滑的、也可以是具有粗糙纹理的,使触控板外观符合产品美学设计。盖板110可为大致矩形的形状,在一些实施方式中,盖板110的矩形外表面边缘还可以倒圆角。
电路板120具体可以为印制电路板(Printed Circuit Board,PCB)或者带补强的柔性电路板(Flexible Printed Circuit,FPC)。通过在电路板120板上经过表面贴装技术(Surface Mounted Technology,SMT)贴片上件,或经过双列直插封装(Dual In-line Package,DIP)配置触摸传感器、行程开关101、连接器和其他电子元件可形成印制电路板装配件(Printed Circuit Board Assembly,PCBA)。该PCBA可用于实现触控板的触摸感应以及按压检测功能。可选地,该PCBA可通过连接器和笔电键盘或皮套键盘实现通讯功能。可选地,PCBA中的触摸传感器具体为内置于电路板120中的触摸感应层。
行程开关101可包括凸起于电路板120下表面的弹性结构以及设置于电路板120下表面的导通点。配合于该行程开关101,固定平台240朝向电路板120的表面设置有触点241,该触点241可以为固定平台240中朝向电路板120凸起的凸起结构。在用户未按压于盖板110的情况下,弹性结构可以与触点241相互接触或者相互分离,此时,该弹性结构的状态为其初始状态或者默认状态。在弹性结构与触点241相互分离的情况下,弹性结构的初始状态为未形变状态。在弹性结构与触点241相互接触的情况下,该弹性结构的初始状态可为微形变状态或者未形变状态。
在用户手指按压于盖板110的情况下,该行程开关101中的弹性结构可沿按压方向 移动并接触于触点241以使得弹性结构形变,形变后的弹性结构接触于电路板120的导通点以使得该行程开关101导通。在用户手指撤回对盖板110的按压作用力后,该形变的弹性结构能够恢复至初始状态,该弹性结构未与电路板120的导通点接触,从而使得行程开关101关断。在该行程开关101中,弹性结构在按压方向上的移动行程可以理解为该行程开关101的按压行程。作为一种可能的实施例,该行程开关101中的弹性结构可以为锅仔片,该行程开关可以理解为dome键。或者,在一些替代实施例中,该行程开关101除了可以为dome键以外,还可以为switch开关,本申请实施例对该行程开关101的具体实现方式不做限定。
可选地,如图2和图3所示,行程开关101可通过粘接或SMT的方式固定于电路板120下表面的中心区域。或者,在其它实施例中,行程开关101的位置还可以根据需要设置于电路板120下表面的其它位置。
除了上述触控组件100,触控板10还包括支撑组件200,用于支撑该触控组件100。
具体地,在支撑组件200中,主支撑件210可以为框型的支撑件,其设置于电路板120的下表面的边缘。可选地,该主支撑件210可以通过连接件(例如胶层201)连接于电路板120的下表面的边缘。
该主支撑件210的形态可以适配于电路板120的形态,例如,在电路板120为矩形电路板的情况下,该主支撑件210可以为矩形框型。另外,该主支撑件210需具有一定的刚度和强度,以能够保障对触控组件100的可靠支撑,且提升触控板10的整体强度。
另外,在支撑组件200中,固定平台240为固定设置的部件。触控板10可以通过该固定平台240安装于电子设备,且该固定平台240可以稳定的固定于电子设备中。该固定平台240也需具有一定的刚度和强度,以能够保障对触控组件100的可靠支撑,且提升触控板10的整体强度。
在本申请实施例中,固定平台240与主支撑件210之间可通过第一弹性件220和第二弹性件230相互连接。具体地,第一弹性件220连接于主支撑件210的第一边211与固定平台240之间,且第二弹性件230连接于主支撑件210的第二边212与固定平台240之间。在用户按压于触控组件100的情况下,触控组件100带动与其连接的主支撑件210向按压方向移动,第一弹性件220与第二弹性件230在按压力的作用下发生弹性形变,触控组件100中的行程开关101可接触于固定平台240上的触点241,以检测用户的按压。在用户的按压力撤回后,该第一弹性件220与第二弹性件230可恢复原状,该两个弹性件与主支撑件210以及固定平台240可对触控组件100起到良好的支撑作用。
另外,第一弹性件220与第二弹性件230沿主支撑件210所在平面对称连接于主支撑件210,以使得该第一弹性件220与第二弹性件230在触控板10中具有良好的对称性,二者可以分别适应于用户在触控板10中两个对称区域的按压,以向用户提供均衡的力度反馈。
综上,通过本申请实施例的技术方案,触控组件100与具有两个弹性件的支撑组件200相互组成的触控板10,不仅可以实现全域按压,而且还可以向用户提供均衡的力度反馈,该触控板10的整体性能较优,能够较佳的适用于各种类型的电子设备且能够提升用户的使用体验。
在该上述图3所示实施例中,虽然用户按压于触控组件100的任意位置,均能实现触控板10的按压检测,但当用户按压于触控组件100的一端时,另一端在没有约束的情 况下会发生翘起。此时,翘起的触控组件100会影响其行程开关101的按压行程,从而影响该行程开关101与触点241之间相互接触,以影响触控板10的按压检测性能。
鉴于此,在图3所示实施例的基础上,图4示出了本申请实施例提供的另一触控板10的示意性爆炸图。
如图4所示,支撑组件200还包括:第一附接件250和第二附接件260,该第一附接件250附接于第一弹性件220的上表面,该第二附接件260附接于第二弹性件230的上表面。
图5示出了图4中第一弹性件220、第二弹性件230、第一附接件250以及第二附接件260的一种示意性放大图。图6示出了第一弹性件220、第二弹性件230、第一附接件250以及第二附接件260组装后的示意性俯视图。其中,图6中的(b)图为图6中的(a)图中A部分的放大示意图。
结合图5和图6所示,第一附接件250具有延伸至第二弹性件230上方的第一凸部2501,且第二附接件260具有延伸至第一弹性件220上方的第二凸部2601。
可选地,第一附接件250和第一弹性件220的第一侧为靠近于主支撑件210的第一边211的一侧,其中,第一弹性件220的第一侧连接于主支撑件210的第一边211。相对的,第一附接件250和第一弹性件220的第二侧为远离于主支撑件210的第一边211的一侧。
类似地,第二附接件260和第二弹性件230的第一侧为靠近于主支撑件210的第二边212的一侧,其中,第二弹性件220的第一侧连接于主支撑件210的第二边212。相对的,第二附接件260和第二弹性件230的第二侧为远离于主支撑件210的第二边212的一侧。第一弹性件220在第一侧与第二侧之间设置有连接于固定平台240的弹性连接件。第二弹性件230在第一侧与第二侧之间设置有连接于固定平台240的弹性连接件。在用户按压于触控组件100时,第一弹性件220在第一侧与第二侧之间连接于固定平台240的弹性连接件可作为第一弹性件220的受力支点,第二弹性件230在第一侧与第二侧之间连接于固定平台240的弹性连接件可作为第二弹性件230的受力支点。
第一附接件250的第二侧设置有第一凸部2501,且第二附接件260的第二侧设置有第二凸部2601。在该情况下,第一凸部2501延伸设置于第二弹性件230的第二侧的上方,第二凸部2601也延伸设置于第一弹性件220的第二侧的上方。
在用户按压于触控组件100中靠近于主支撑件210的第一边211的区域时,第一弹性件220的第一侧向下运动,对应的,第一弹性件220的第二侧向上运动。此时,第一弹性件220的第二侧可作用于位于其上方的第二附接件260的第二凸部2601,使得该第二附接件260带动第二弹性件230的第二侧向上运动,且第二附接件260以及第二弹性件230的第一侧向下运动。在第二弹性件230的第一侧向下运动的情况下,连接于第二弹性件230的第一侧的主支撑件210的第二边212也会带动触控组件100靠近于主支撑件210的第二边212的区域向下运动。因此,用户按压于触控组件100中靠近于主支撑件210的第一边211的区域时,触控组件100中靠近于主支撑件210的第二边212的区域不会翘起,从而进一步改善触控板10的按压检测性能。
类似地,在用户按压于触控组件100中靠近于主支撑件210的第二边212的区域时,第二弹性件230的第一侧向下运动,对应的,第二弹性件230的第二侧向上运动。此时,第二弹性件230的第二侧可作用于位于其上方的第一附接件250的第一凸部2501,使得 该第一附接件250带动第一弹性件220的第二侧向上运动,且第一附接件250以及第一弹性件220的第一侧向下运动。在第一弹性件220的第一侧向下运动的情况下,连接于第一弹性件220的第一侧的主支撑件210的第一边211也会带动触控组件100靠近于主支撑件210的第一边211的区域向下运动。因此,用户按压于触控组件100中靠近于主支撑件210的第二边212的区域时,触控组件100中靠近于主支撑件210的第一边211的区域不会翘起,从而进一步改善触控板10的按压检测性能。
综上,通过本申请实施例的技术方案,当用户按压于触控组件100的一端时,例如,当用户按压于触控组件100中靠近于主支撑件210的第一边211的端部区域或者按压触控组件100中靠近于主支撑件210的第二边212的端部区域时,触控组件100的另一端在弹性件和连接件的共同作用下不会发生翘起,以进一步改善触控板10的按压检测性能。
第一附接件250和第二附接件260除了可改善触控板10的按压检测性能以外,该第一附接件250附接于上述第一弹性件220还可以对该第一弹性件220进行补强,第二附接件260附接于上述第二弹性件230还可以对该第二弹性件230进行补强。
可选地,如图3至图6所示,第一弹性件220和第二弹性件230均为片状件。虽然该片状的第一弹性件220和第二弹性件230弹性较好,但强度偏弱。鉴于此,在本申请实施例中,在支撑组件200中增加第一附接件250和第二附接件260,该第一附接件250和第二附接件260也可以为片状件,因而易于附接于第一弹性件220和第二弹性件230。另外,该第一附接件250的形状可以适配于第一弹性件220,且第二附接件260的形状可以适配于第二弹性件230。该第一附接件250和第二附接件260可以对第一弹性件220和第二弹性件230的主体区域起较佳的支撑和补强作用。
结合第一附接件250和第二附接件260,在保障第一弹性件220和第二弹性件230的弹性形变的同时,还可以保障第一弹性件220和第二弹性件230的使用可靠性以及使用寿命。
可选地,如图3至图6所示,第一弹性件220和第二弹性件230的形状相同。对应的,第一附接件250和第二附接件260的形状可相近或相同。该第一附接件250和第二附接件260可以设置于第一弹性件220和第二弹性件230的上表面。在该情况下,该第一附接件250和第二附接件260可以容纳于框型主支撑件210的中空区域中。
可选地,为保障第一弹性件220和第二弹性件230的弹性性能,该第一弹性件220和第二弹性件230的厚度较薄。为保障第一附接件250和第二附接件260的补强性能,该第一附接件250和第二附接件260的厚度可较厚。作为示例,该第一附接件250和第二附接件260的厚度可大于第一弹性件220和第二弹性件230的厚度。
在一些实施方式中,触控组件100为矩形触控组件,返回参考图5所示,第一弹性件220具有平行于矩形触控组件的长边方向的两条第一弹性臂221以及连接两条第一弹性臂221的第一中间部222,第二弹性件230具有平行于矩形触控组件的长边方向的两条第二弹性臂231以及连接两条第二弹性臂231的第二中间部232。在平行于矩形触控组件的长边方向上,两条第一弹性臂221与两条第二弹性臂231相互对应且具有间隙。
通过该实施方式的技术方案,第一弹性件220的两条第一弹性臂221以及第二弹性件230的两条第二弹性臂231均平行于矩形触控组件的长边方向,使得该第一弹性件220和第二弹性件230能够较佳的保障用户在触控组件100的长边方向上的按压手感且保障触控板10对用户按压的检测。另外,两条第一弹性臂221和两条第二弹性臂231可沿矩 形触控组件的短边方向分布,对应地,沿短边方向分布的两条第一弹性臂221可由沿长边方向分布的第一中间部222连接,沿短边方向分布的两条第二弹性臂231可由沿长边方向分布的第二中间部232连接,这同样也可保障用户在触控组件100的短边方向上的按压。
可选地,参见图5所示,第一中间部222和第二中间部232中可形成有通孔,以降低该第一弹性件220和第二弹性件230的整体重量,且可为触控板10中其它器件提供容纳空间,例如为电路板120下表面的元器件提供容纳空间。
或者,在其它替代实施方式中,第一中间部222和第二中间部232也可以为实心部,即其中不设置有通孔,以保障第一弹性件220和第二弹性件230的使用可靠性,并且该实心部的设定位置需避开触控板10中其他器件,例如电路板120下表面的元器件。
可选地,在第一弹性件220中,第一中间部222朝向主支撑件210的第一边211的一侧设置有至少一个第一弹性连接件2221,该第一弹性件220通过该至少一个第一弹性连接件2221连接于主支撑件210的第一边211。对应的,第一中间部222远离主支撑件210的第一边211的另一侧设置有至少一个第二弹性连接件2222,第一弹性件220通过该至少一个第二弹性连接件2222连接于固定平台240。作为示例,在图5所示实施例中,第一中间部222的两侧分别设置有两个第一弹性连接件2221和两个第二弹性连接件2222。
该连接于固定平台240的至少一个第四弹性连接件2322设置于两条第一弹性臂221之间,且位于第一弹性件220靠近于主支撑件210的第一边211的第一侧与远离于主支撑件210的第一边211的第二侧之间。在用户按压于触控组件100时,该至少一个第四弹性连接件2322可作为第一弹性件220的受力支点。
在一些实施方式中,该至少一个第一弹性连接件2221和至少一个第二弹性连接件2222与第一中间部222可一体形成,此时,该至少一个第一弹性连接件2221和至少一个第二弹性连接件2222可理解为设置于第一中间部222上的悬臂梁结构。或者,在另一些实施方式中,该至少一个第一弹性连接件2221和至少一个第二弹性连接件2222与第一中间部222也可以为分体结构,至少一个第一弹性连接件2221和至少一个第二弹性连接件2222通过胶层、焊接或者其它连接方式连接于第一中间部222。
可以理解的是,在第一弹性件220通过至少一个第一弹性连接件2221连接于主支撑件210的第一边211后,第一弹性连接件2221除了两端区域外,其中间区域处于悬空状态,从而可保证第一弹性件220与主支撑件210的第一边211的弹性连接。且在第一弹性件220通过至少一个第二弹性连接件2222连接于固定平台240后,第二弹性连接件2222除了两端区域外,其中间区域处于悬空状态,从而可保证第一弹性件220与固定平台240的第一边211的弹性连接。
类似于上述第一弹性件220,在第二弹性件230中,第二中间部232朝向主支撑件210的第二边212的一侧设置有至少一个第三弹性连接件2321,第二弹性件230通过至少一个第三弹性连接件2321连接于主支撑件210的第二边212。第二中间部232远离主支撑件210的第二边212的另一侧设置有至少一个第四弹性连接件2322,第二弹性件230通过该至少一个第四弹性连接件2322连接于固定平台240。作为示例,在图5所示实施例中,第二中间部232的两侧分别设置有两个第三弹性连接件2321和两个第四弹性连接件2322。具体地,该第二弹性件230中第三弹性连接件2321和第四弹性连接件2322的 相关设计可以参见上文对于第一弹性连接件2221和第二弹性连接件2222的相关描述,此处不做过多赘述。
通过本申请实施例的技术方案,在第一弹性件220的第一中间部222的两侧分别设置弹性连接件,且在第二弹性件230的第二中间部232的两侧分别设置弹性连接件,以实现第一弹性件220与第二弹性件230在主支撑件210与固定平台240之间的弹性连接,使得用户在按压触控组件100时,带动第一弹性件220和第二弹性件230产生形变。整体方式易于实现且第一弹性件220和第二弹性件230与主支撑件210和固定平台240之间的连接区域较小,能有效保障第一弹性件220和第二弹性件230的弹性形变,从而保障触控板10的按压性能。
对应于上述第一弹性件220和第二弹性件230,继续参见图5所示,第一附接件250具有附接于两条第一弹性臂221上表面的两条第一连接臂251,第二附接件260具有附接于两条第二弹性臂231上表面的两条第二连接臂261。两条第一连接臂251与两条第二连接臂261相互对应且具有间隙,两条第一连接臂251朝向两条第二连接臂261的一端设置有位于两条第二弹性臂231上方的第一凸部2501,两条第二连接臂261朝向两条第一连接臂251的一端设置有位于两条第一弹性臂221上方的第二凸部2601。
具体地,在该实施方式中,第一附接件250的两条第一连接臂251附接于第一弹性件220上表面的两条第一弹性臂221,以对该两条第一弹性臂221进行支撑和补强。类似地,第二附接件260的两条第一连接臂261附接于第二弹性件230上表面的两条第二弹性臂231,以对该两条第二弹性臂231进行支撑和补强。可选地,第一附接件250和第二附接件260可通过粘附、焊接、冲压等方式分别附接于第一弹性件220和第二弹性件230的上表面。
该两条第一连接臂251朝向两条第二连接臂261的一端设置有两个第一凸部2501,该两个第一凸部2501位于两条第二弹性臂231的上方。在用户按压于触控组件100的情况下,该两个第一凸部2501作用于两条第二弹性臂231的端部。两条第二连接臂261朝向两条第一连接臂251的一端设置有两个第二凸部2601,该两个第二凸部2601位于两条第一弹性臂221的上方。在用户按压于触控组件100的情况下,该两个第二凸部2601作用于两条第一弹性臂221的端部。
可以理解的是,第一附接件250中还具有连接两条第一连接臂251的中间部,且第二附接件260中也具有连接两条第二连接臂261的中间部。该第一附接件250的中间部可附接于第一弹性件220的第一中间部222,该第二附接件260的中间部附接于第二弹性件230的第二中间部232。
在第一中间部222和第二中间部232具有通孔的情况下,该第一附接件250的中间部以及第二附接件260的中间部同样可形成有通孔,以降低该第一附接件250和第二附接件260的整体重量,且可为触控板10中其它器件提供容纳空间,例如为电路板120下表面的元器件提供容纳空间。
参见图5和图6所示,两条第一连接臂251的第一凸部2501对应的凹部用于容纳两条第二连接臂261的第二凸部2601。两条第二连接臂261的第二凸部2601对应的凹部用于容纳两条第一连接臂251的第一凸部2501。
通过该实施方式的技术方案,两条第一连接臂251和两条第二连接臂261之间的第一凸部2501和第二凸部2601可以相互适配,不会造成额外的空间浪费,且较为可靠的 保障触控板10的按压检测性能。在一些实施方式中,支撑组件200中至少一个部件设置有压点槽,该压点槽可用于控制该至少一个部件的平面度。
作为示例,支撑组件200中的主支撑件210、第一弹性件220、第二弹性件230、第一附接件250以及第二附接件260均设置有压点槽。该压点槽可设置于该每一部件的上下两面,以调整每一部件的平面度。
具体地,支撑组件200中任一部件的平面度过大会导致触控板10的按压力的一致性较差,即出现在触控板10不同位置按压需要不同大小的力,并且按压力的波动也会较大,另外平面度较大,按压行程也需要考虑平面度的影响,因而会导致触控板按压行程较大,从而影响用户体验。因此,通过压点槽进行平面度管控设计可以进一步优化触控板10的性能参数,提高用户使用体验。
在一些实施方式中,压点槽可以为边长为0.15mm的正方形槽,可替代的,压点槽也可以为圆形槽或其他多边形槽,且其在主支撑件210、固定平台240、弹性件220、230和连接件250、260上的深度各不相同。作为示例,主支撑件210上压点槽的深度可为0.06mm至1mm,用于控制主支撑件210的平面度小于0.15mm。固定平台240上压点槽的深度可为0.04mm至0.08mm,用户控制固定平台240的平面度小于0.05mm。第一弹性件220和第二弹性件230上压点槽的深度可为0.02mm至0.05mm。第一附接件250和第二附接件260上压点槽的深度可为0.04mm至0.08mm。
在另一种替代的实施方式中,还可以基于支撑组件200中某两个部件的整体在其上下两面设置压点槽,用于控制该两个部件的整体的平整度。作为示例,主支撑件210、固定平台240的上下两面均设置压点槽,而第一弹性件220、第二弹性件230、第一附接件250以及第二附接件260仅一面设置压点槽,即第一弹性件220和第一附接件250相接触的面不具有压点槽,第二弹性件230和第二附接件260相接触的面不具有压点槽。
在一些可能的实施方式中,如上文图2至图4所示,固定平台240在触控组件100所在平面上的投影超出该触控组件100。
具体地,触控组件100中的各部件为板状件,该触控组件100所在平面可以为触控组件100中盖板110的所在平面,或者,也可以为电路板120的所在平面。
固定平台240在盖板110所在平面上的投影可超出该盖板110,且该固定平台240在电路板120所在平面上的投影也可超出该电路板120。即在该实施方式中,在平行于触控组件100所在平面的方向,固定平台240具有超出触控组件100的部分,因而,该固定平台240可具有较大的面积,从而对触控组件100起到良好的支撑以及保护作用,提升触控板10的整体稳定性。
在一些实施方式中,触控组件100为矩形组件,即触控组件100中盖板110和电路板120均为矩形。在该情况下,在该触控组件100的长度方向和/或宽度方向上,固定平台240在触控组件100所在平面上的投影超出该触控组件100。
作为示例,如图2至图4所示,固定平台240可在触控组件100的长度方向以及宽度方向上均超出该触控组件100。该固定平台240的面积可以大于触控组件100中任意部件的面积,该固定平台240可以由下往上完全覆盖该触控组件100。在该示例中,固定平台240可以对触控组件100起到较为完善的保护和支撑作用。
或者,在另一示例中,图7示出了本申请实施例提供的另一触控板10的示意性爆炸图。
如图7所示,在本申请实施例中,固定平台240可在触控组件100的宽度方向上超出该触控组件100。但该固定平台240在触控组件100的长度方向上未超出该触控组件100。在该示例中,固定平台240虽然未由下往上完全覆盖触控组件100,但该固定平台240的整体面积可适当减小,有利于降低触控板10的整体重量,也有降低该触控板10在电子设备中所需占用的空间。
可选地,在一些实施方式中,固定平台240超出触控组件100的部分设置有安装件,该安装件用于将固定平台240安装于触控板10所在的电子设备。
作为示例,安装件包括但不限于是螺孔和螺钉、卡扣、胶层等用于实现连接安装的部件。具体地,在安装件包括螺孔和螺钉的情况下,固定平台240的边缘区域可设置于螺孔,螺钉通过螺孔可将固定平台240固定安装于电子设备。
在触控板10所在电子设备为笔记本电脑的情况下,安装件可将触控板10安装于笔记本电脑的C壳,即笔记本电脑中键盘所在面的壳体。例如,C壳中具有用于容纳该触控板10的通孔,安装件可将固定平台240安装于通孔的边缘,以使得触控板10安装并容纳于该C壳的通孔处。
通过该实施方式的技术方案,可以直接利用固定平台240将触控板10安装于电子设备,整体安装方式易于实现且可靠性较高,有利于提升触控板10在电子设备中的装配效率,也便于其拆卸和维修。
图8示出了上文图4和图7所示实施例中的固定平台240的结构示意图。其中,图8中的(a)图对应于图4所示实施例中的固定平台240,图8中的(b)图对应于图7所示实施例中的固定平台240。
如图8所示,在本申请实施例中,固定平台240的中心区域设置有朝向触控组件100的凸起部242。触点241可位于该凸起部242的中心区域。
可选地,该凸起部242可以为矩形凸起部,该矩形凸起部可适配于第一弹性件220和第二弹性件230围合形成的矩形空间。可选地,该触点241可以为位于凸起部242的中心区域的凸点,该触点241的面积和高度可以根据电路板120上的行程开关101进行相应设计,以使得该触点241能够有效接触并触发行程开关101。结合图2至图8所示,第一弹性件220和第二弹性件230可连接于该凸起部242,以实现第一弹性件220和第二弹性件230与固定平台240的相互连接。且第一弹性件220和第二弹性件230与固定平台240中除该凸起部242的其它区域之间具有间隙。
具体地,第一弹性件220的第一中间部222上的至少一个第二弹性连接件2222可连接于凸起部242的上表面靠近第一中间部222的边缘,以实现第一弹性件220与固定平台240的相互连接。第二弹性件230的第二中间部232上的至少一个第四弹性连接件2322可连接于凸起部242的上表面靠近第二中间部232的边缘,以实现第二弹性件230与固定平台240的相互连接。应理解,第一弹性件220的第一弹性连接件2221和第二弹性件230的第三弹性连接件2321仅分别与主支撑件210连接,第一弹性连接件2221与第二弹性连接件2321均与固定平台240之间具有间隙。
在本申请实施例中,第一弹性件220和第二弹性件230与固定平台240中除凸起部242以外的其它区域之间具有间隙,该间隙能够提供第一弹性件220和第二弹性件230的形变空间,以保障触控组件100能够在用户的按压作用下向下位移,从而保障触控板10的按压检测功能。
通过该实施例的技术方案,在固定平台240的中心区域设置凸起部242,可以便于凸起部242配合于第一弹性件220和第二弹性件230实现触控板10的按压检测功能,且也便于固定平台240的面积设计较大,例如,固定平台240具有超出触控组件100的部分,从而对触控组件100起到可靠的支撑和保护作用。
图9示出了图4所示实施例中第一弹性件220和第二弹性件230与固定平台240的组装结构示意图。
如图9所示,在本申请实施例中,第一弹性件220和第二弹性件230沿平行于触控板10的短边方向对称设置,并围合形成对应于凸起部242的开口区域。
具体地,该第一弹性件220的两个第一弹性臂221和第二弹性件230的两个第二弹性臂232设置于凸起部242的外围,当用户按压于触控组件100时,凸起部242不会对该第一弹性件220的两个第一弹性臂221和第二弹性件230的两个第二弹性臂232造成干涉和影响。另外,该第一弹性件220的两个第一弹性臂221和第二弹性件230两个第二弹性臂232可均匀对称分布于触控板10中,以进一步提升触控板10的按压均匀性,从而向用户提供均衡的力度反馈。
第一弹性件220的两个第一弹性臂221和第二弹性件230的两个第二弹性臂231设置于凸起部242平行于触控板10短边方向的两边的外围,第一弹性件220的第一中间部222和第二弹性件230的第二中间部232设置于凸起部242平行于触控板10长边方向的两边的外围。该凸起部242平行于触控板10长边方向的两边分别通过至少一个第二弹性连接件2222和至少一个第四弹性连接件2322与第一中间部222和第二中间部232连接。
通过该实施方式的技术方案,凸起部242不会对第一弹性件220和第二弹性件230的弹性形变造成干涉和影响,以较为可靠的保障触控板10的按压检测性能。
可选地,参见图8和图9所示,上述申请实施例中的凸起部242可以为空心凸起部。例如,该空心凸起部242可以为通过对固定平台240进行冲压成型的形成的空心凸台。
通过该实施例的技术方案,凸起部242易于形成于固定平台240中,固定平台240整体的重量较小且成本较低。
或者,在另一些可能的实施方式中,凸起部242也可以为实心凸起部。例如,可以在固定平台240的上表面设置实心补强部,该实心补强部不仅可以形成固定平台240表面的凸起,还可以提高固定平台240与第一弹性件220和第二弹性件230之间的连接强度。
在该实施方式下,图10示出了本申请实施例提供的另一固定平台240的示意性爆炸图。
如图10所示,固定平台240为板状结构,其上表面可设置补强部,具体地,其上表面的中心区域可设置有“工”字形补强板,该补强板与固定平台240相互连接后,即可形成固定平台240表面的凸起部242。
可选地,该补强板可以通过螺钉、胶层、焊接等各种方式连接于固定平台。作为示例,图10中所示的补强板为“工”字形,在其它替代实施方式中,该补强板还可以根据实际需要调整为其它形状,本申请实施例对此不做具体限定。
结合图8和图10所示,在本申请实施例提供的几种固定平台240中,均设置有一个或者多个通孔,该通孔可用于降低固定平台240的重量,且也可用于避让触控板10所在电子设备中其它元器件,从而优化触控板10及其所在电子设备的整体性能。
可选地,在图8所示实施例中,通孔可设置于固定平台240的凸起部242,或者,该通孔也可设置于固定平台240的非凸起区域。在图10所示实施例中,凸起部242作为补强部,可不设置有通孔,而仅在固定平台240的主体板状部设置有通孔。
基于该图10所示的固定平台240,图11示出了包括该固定平台240的另一触控板10的示意性爆炸图。
如图11所示,在该触控板10中,各部件的功能可以与上文图4和图7所示实施例中各部件的功能相同。差异在于本申请实施例部分部件的形状设计与上文图4和图7所示实施例中部分部件的形状设计不同。
具体地,在该触控板10中,固定平台240的相关设计不同于图4和图7所示实施例中固定平台240的相关设计,该固定平台240的相关技术方案可以参见上文图10所示实施例的相关描述。
另外,第一弹性件220和第二弹性件230的形状设计与图4和图7所示实施例中两个弹性件的形状设计略有不同。在本申请实施例中,第一弹性件220的第一中间部222和第二弹性件230的第二中间部232未设置有通孔,而为实体臂结构。配合于该第一弹性件220和第二弹性件230的实体中间部,第一附接件250和第二附接件260的中间部也为实体中间部,而未设置有通孔。
在本申请实施例中,触控板10可通过固定平台240安装于电子设备,例如,安装于笔记本电脑的C壳。固定平台240虽然可通过弹性连接件间接支撑主支撑件210以及触控组件100,但主支撑件210以及触控组件100的稳定性不佳。且由于触控板10中各部件的制造公差以及装配公差,也会造成触控板10的整体厚度会发生变化,因而在触控板10安装于电子设备后,会造成触控组件100凸起或凹陷于的现象。
鉴于此,在本申请的一些实施方式中,主支撑件210在矩形框型的基础上还可进一步设置有限位部213,该限位部213用于实现主支撑件210的限位。
例如,如图11所示,主支撑件210的第一边211和/或第二边212上设置有限位部213。作为示例,主支撑件210的第一边211和第二边212上均设置有两个限位部213。配合于该限位部213,触控板10所在的电子设备中可设置有限位孔,例如,笔记本电脑的C壳中设置有限位孔,当触控板10安装于C壳后,主支撑件210上的限位部213可容纳于限位孔中,以保障主支撑件210在C壳中的相对位置固定,防止连接于主支撑件210的触控组件100凸起或凹陷于C壳,造成触控板10在C壳中的装配效果不佳。在装配效果不佳的情况下,不仅影响触控板10的外观美观度,也会影响用户对于触控板10的按压使用体验。类似于该图11中所示的主支撑件210,上文图4和图7所示实施例中的主支撑件210也可以设置有限位部213,以对主支撑件210和与其连接的触控组件100在电子设备中的安装起到限位作用。
在具体实现上,限位部213可以为设置于主支撑件210的框型主体外围的凸起部。该限位部213的形状、尺寸和数量可以根据实际需求进行设计。作为示例,如图11所示,四个限位部213可以设置于主支撑件210的框型主体的四角,从而对主支撑件210起到较为可靠的限位作用。该限位部213包括但不限于是块状或板状结构。通过该实施例的技术方案,主支撑件210作为触控板10中的中心部件,保障了触控板10整体的强度和结构稳定性,在主支撑件210上设置限位部213,以实现主支撑件210以及与其连接的触控组件100在电子设备中的限位,从而较为可靠的保障触控板10在电子设备中的安装和 使用。
除了在电子设备的C壳中设置限位孔配合主支撑件210的限位部213以外,在另一些实施方式中,也可以在固定平台240中设置限位孔,以对该主支撑件210进行限位。
图12示出了本申请实施例提供的一种主支撑件210和固定平台240的示意性爆炸图和装配图。
如图12所示,该固定平台240可以与图4中的固定平台240的形貌近似,差别在于,本申请实施例中的固定平台240的边缘向上弯曲形成有台阶结构243,该台阶结构243的侧壁形成有限位孔244。该限位孔244可以与主支撑件210上的限位部213相互配合,以使得该固定平台240对主支撑件210进行限位。
通过该实施例的技术方案,可以利用触控板10中的固定平台240实现对主支撑件210的限位,而不需要额外在电子设备中设置限位孔。在保障主支撑件210以及与其连接的触控组件100可具有相对稳固的结构的同时,可以简化触控板10在电子设备中的安装,也便于其拆卸和维修。
在一些实施方式中,在垂直于触控组件100的方向上,限位孔244的尺寸大于限位部213的尺寸。
在限位部213安装于限位孔244后,该限位部213的上表面可抵接于限位孔244的孔壁。当用户按压于触控组件100时,限位部213可跟随主支撑件210在限位孔244中向下运动,该较大的限位孔244可提供限位部213一定的下移空间同时限定限位部213的下移限度,从而便于用户在触控组件100上的按压并且防止触控组件100过度下移塌陷,提升用户对触控板10的使用体验。
可选地,在图12所示实施例中,固定平台240可以为矩形平台,该固定平台240的两个短边所在的边缘向上弯曲形成两个条状的台阶结构243。该两个台阶结构243可分别对应于主支撑件210中设置有限位部213的两个边。
可选地,该台阶结构243的台阶面可设置有安装件,例如,螺孔和螺钉等,用于实现固定平台240在电子设备中的安装。
可以理解的是,图12仅作为示意,在图4所示实施例的固定平台240的基础上示出了另一种具有台阶结构243的固定平台240。除图12所示实施例以外,图11所示实施例中的固定平台240的边缘也可向上弯曲形成台阶结构243,且该台阶结构243的侧壁形成有限位孔244。或者,在图7所示实施例中,固定平台240的台阶结构的侧壁同样可形成有限位孔244。
可选地,在上文各实施例中,固定平台240上的触点241可以为凸起部242中朝向触控组件100凸起的凸台。在一些相关技术方案中,该凸台也可以称之为“导电基”。该凸台与凸起部242可以为一体式结构,或者,也可以为分体式结构。在具体实现上,该凸台可以用金属或者硅胶实现。
在该实施例中,固定平台240用于配合行程开关101的触点241实现方式简单,制造成本较低,有利于提高触控板10的生产制造效率,且降低触控板10的整体制造成本。
除了上述申请实施例的凸台以外,图13示出了本申请实施例提供的另一触点241的实现方式示意图。
如图13所示,在本申请实施例中,触点241可以为安装于凸起部242的调节螺丝2411,该调节螺丝2411相对于凸起部242的高度能够被调节。
可选地,配合于该调节螺丝2411,凸起部242上可设置有螺母2412,以便于调节螺丝2411在凸起部242上的安装。调节螺丝2411穿过螺母2412并凸出于凸起部242,调节螺丝2411凸出于凸起部242的高度可以被调节,即该调节螺丝2411与行程开关101之间的距离和相互作用力可以被调节。
通过该实施方式的技术方案,该可调节高度的调节螺丝2411能够更好的适配于行程开关101,使得该行程开关101对于按压压力的感应更为灵敏和准确。另外,该可调节高度的调节螺丝2411还能够容忍固定平台240的变形和行程开关101的厚度公差,换言之,即使在固定平台240具有形变和/或行程开关101具有厚度公差的情况下,可通过调节螺丝2411,从而调节调节螺丝2411与行程开关101之间的距离和相互作用力,以保证行程开关101与调节螺丝2411的良好配合从而保证触控板10的按压检测性能。
图14示出了本申请实施例提供的另一触点241的实现方式示意图。
如图14所示,在本申请实施例中,触点241为设置于凸起部242的T形螺钉2413,该T形螺钉2413的头部朝向行程开关101,且该T形螺钉2413通过胶层2414固定于凸起部242中的开孔2421。
具体地,凸起部242中可形成有开孔2421,该开孔2421的孔径可以大于T形螺钉2413的杆部的直径,且小于T形螺钉2413的头部的直径。在该情况下,T形螺钉2413的杆部可穿过开孔2421,但T形螺钉2413的头部限位于开孔2421的上方。
在触控板10的装配过程中,T形螺钉2413的头部可抵接于行程开关101,预压装置可将预设作用力施加于T形螺钉2413的底部,该预设作用力可根据用户按压触控板10的实际按压力进行调节和设计。在该预压作用力下,T形螺钉2413与行程开关101可以处于预压状态,该状态能够灵敏的检测用户在触控板10上的按压。
在预压装置将预设作用力施加于T形螺钉2413的底部的同时,为了使得T形螺钉2413能够保持预压状态,可通过在开孔2421中点胶形成胶层2414,从而将T形螺钉2413固定于该开孔2421。T形螺钉2413的头部可以防止胶层2414溢出至行程开关101,保障行程开关101的可靠使用。
通过该实施方式的技术方案,不需要通过调节螺丝2411调节与行程开关101之间的距离和相互作用力,而可以通过T形螺钉2413与胶层2414的相互配合,使得T形螺钉2413和行程开关101能够保持在适配于用户按压作用下的预压状态,从而更为灵敏且便捷的检测用户在触控板10上的按压,也能保障用户在触控板10上的按压手感。
可以理解的是,该图13和图14中所示的调节螺丝2411以及T形螺钉2413的相关技术方案也可以应用于上文图2至图12任意所示实施例中,即将图3至图12所示任意实施例中触点241所在的凸台替换为调节螺丝2411或T形螺钉2413即可。
作为示例,在图4所示实施例的基础上,图15示出了本申请实施例提供的另一触控板10的示意性爆炸图。
如图15所示,在固定平台240中,将图4所示实施例中触点241的凸台替换为了调节螺丝2411,且凸起部242的中心区域设置有螺母2412,以配合于调节螺丝2411在凸起部242中的安装。
另外,在图15所示实施例中,触控板10除了可以包括上文实施例中触控组件100和支撑组件200的各部件以外,还可以包括导电布300。
该导电布300可连接于触控组件100中的电路板120以及支撑组件200中的主支撑 件210。该导电布300可用于将电路板120上产生的静电通过主支撑件210导出至触控板10以外,以防止静电对触控板10中的各组件造成损坏。
可以理解的是,该导电布300除了可应用于图15所示实施例以外,还可以应用于上文图2至图14任意所示实施例中,以提供各实施例的触控板10的静电防护。
本申请实施例还提供了一种电子设备,该电子设备包括壳体以及上述任一申请实施例中的触控板10,该触控板安装于该壳体且用于向电子设备提供按压检测功能。
作为示例而非限定,本申请实施例中的电子设备可以为终端设备、手机、平板电脑及其配件键盘、笔记本电脑、台式机电脑、游戏设备、车载电子设备或穿戴式智能设备等便携式或移动计算设备,以及电子数据库、汽车、银行自动柜员机(ATM)等其他电子设备。该穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或部分功能的设备,例如智能手表或智能眼镜等,以及包括只专注于某一类应用功能并且需要和其它设备如智能手机配合使用的设备,例如各类进行体征监测的智能手环、智能首饰等设备。
可选地,在电子设备为笔记本电脑的情况下,用于安装触控板10的壳体可以为笔记本电脑的C壳,即笔记本电脑中键盘所在面的壳体。
需要说明的是,在不冲突的前提下,本申请描述的各个实施例和/或各个实施例中的技术特征可以任意的相互组合,组合之后得到的技术方案也应落入本申请的保护范围。
应理解,本申请实施例中的具体的例子只是为了帮助本领域技术人员更好地理解本申请实施例,而非限制本申请实施例的范围,本领域技术人员可以在上述实施例的基础上进行各种改进和变形,而这些改进或者变形均落在本申请的保护范围内。
以上所述,仅为本申请的具体实施方式,但本申请的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本申请揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本申请的保护范围之内。因此,本申请的保护范围应以所述权利要求的保护范围为准。
