现有的可穿戴设备中由于触控线路层紧贴玻璃盖板的背部,且玻璃盖板抵扣在面框内圈的平台上,使得垂直方向上柔性线路弯折段与面框的结构相互阻碍,进而现有技术增大柔性线路与触控线路层的接合区,减小弯折段的空间,所导致的触控线路层的接合区变大,使得最终屏幕显示的黑边加大,影响了用户体验且触屏功能容易失灵。本发明实施例提供一种触控设备的组合结构,下面结合附图与实施例对本发明作进一步说明。
请参考图1和图2,本发明实施例一方面提供了一种触控设备的组合结构,包括:环形外框10;玻璃盖板20,玻璃盖板20位于环形外框10的中间区域,并与环形外框10连接;触控线路板30、连接于触控线路板30的柔性线路40、以及连接于柔性线路40的主板均设于玻璃盖板20下方;其中,环形外框10的下端设有凹槽11,凹槽11至少用于容置柔性线路40,玻璃盖板20的底面具有阶梯结构21。
本发明实施例中,在环形外框10内部设计有凹槽11,给柔性线路40留出了足够的弯折区域,增大了柔性线路40在触控线路板外的区域,减小柔性线路40和触控线路板30的接触面积。且本发明实施例中,玻璃盖板20的底面具有阶梯结构21,由于阶梯结构21的存在,使得设于玻璃盖板20下的触控线路板30得以有富裕的空间从环形外框10的中间区域向凹槽11区域延伸布置,同样的,柔性线路40与玻璃盖板20的连接区域也可以向凹槽11区域延伸,从而更有效的减少黑边,提升用户体验。
在一些实施例中,阶梯结构21的底面高于凹槽11的顶面,触控线路板30与阶梯结构21紧密结合,从而减小了阶梯结构21上柔性线路40到凹槽11的纵向高度,使得柔性线路40与触控线路板30的连接更为牢固。
在一些实施例中,阶梯结构21的底面低于凹槽11的顶面或与凹槽11的顶面齐平。玻璃盖板20的底面的阶梯结构21,其底面低于凹槽11的顶面或与凹槽11的顶面齐平,使得设于阶梯结构21下的触控线路板30无需弯折设置,即可以有富裕的空间从环形外框10的中间区域向凹槽11区域延伸布置,并且减少了柔性线路在沿触控线路板30方向上的弯折,同样的,柔性线路40与玻璃盖板20的连接区域也可以向凹槽11区域延伸,从而更有效的减少黑边,提升用户体验。
具体的,本发明实施例中的环形外框10可以为类圆形外框,也可以为如长方形、正方形等规则多边环形外框10或不规则多边形外框;凹槽11可以为一直角多边形凹槽11,或弧形凹槽11等具体形状;该组合结构可以应用于智能手表或智能手机等的智能触控设备,当应用于智能手表时可以为圆环形外框10,而应用于智能手机上时可以为长方形外框,当然还可以以其他具体形状应用于更多不同设备,本发明实施例在此不进行一一阐述。本发明实施例中,将自触控线路板30朝向主板方向确定为下方,反之为上方。其中,本发明实施例中的柔性线路40和主板位于玻璃盖板20下方并非特指位于其正下方,只要是在垂直方向上相较于玻璃盖板20更低即可。
具体的,该触控设备组成结构中,玻璃盖板20盖于上方,触控线路板30、显示功能层、以及主板按序自上而下布置,位于玻璃盖板20下方的触控线路板30于边缘处与柔性线路40连接,柔性线路40通过凹槽11弯折后连接至主板。
在一可实施方式中,环形外框10上设有承台12,玻璃盖板20搭设在承台12上。阶梯结构21位于承台12围合的中间空间。
本发明实施例中,通过在环形外框10上设置承台12,一方面可以用于搭载玻璃盖板20,另一方面也可以用于在承台12下延伸柔性线路40,解决了现有技术中柔性线路40的弯折段过于靠近其与触控线路板30接合区,弯折段偏短所导致的容易出现柔性线路40板断裂或柔性线路40从触控线路板30上脱落的问题。其中,承台12可以为一体的环形承台12;也可以为多个凸起,共同承载玻璃盖板20。
在一可实施方式中,触控线路板30包括布线区31,其中,布线区31为触控线路板30与柔性线路40的电连接区域。
在现有技术中,触控线路板30于边缘与柔性线路40连接,该连接部分通常直接位于玻璃盖板20正下方,为了遮挡布线区31以及柔性电路40,从而使用黑色不透明材质进行遮挡,从而造成黑边。而在本发明实施例的一可实施方式中,触控线路板30与柔性线路40的连接区域,也即布线区31至少部分位于承台12下方。具体的,本发明实施例中,可以将触控线路板30部分设于承台12下方,如当承台12为环形时,触控线路板30可以设置于环形承台12正下方任意位置,柔性线路40也可以选择完全在环形承台12正下方的位置与触控线路板30相连接,也即布线区31完全隐藏在承台12下方;当然柔性线路40也可以部分在环形承台12正下方与触控线路板30连接,部分在玻璃盖板20下或其他位置与触控线路板30连接,也即布线区31部分隐藏在承台12下方;但无论哪一种方式都能够大大减少该连接区域,也即布线区31在玻璃盖板20下的暴露区域,有效减少黑边宽度,提升用户体验。同样的,当承台12为多个凸起时,也可以将柔性线路40与触控线路板30的连接区域设置在承台12下方,也即布线区31全部设置在承台12正下方或部分设置在承台12正下方以减少黑边。
在一可实施方式中,触控线路板30与柔性线路40的连接区域,也即布线区31至少部分位于凹槽11内。本发明实施例中,触控线路板30可以自玻璃盖板20下方移至布置到凹槽11区域。具体的,柔性线路40可以在凹槽11区域与触控线路板30相连接;当组合结构中包括有承台12时,也可以部分连接在承台12下方,部分连接在凹槽11内。在一可实施方式中,布线区31全部位于凹槽11内,从而在用户的通过玻璃盖板的可视范围内完全无法看到布线区31,实现无黑边设计。
在一些实施例中,布线区31也可以全部位于由承台12所围合的中间空间下方。
在一可实施方式中,玻璃盖板20与环形外框10之间设有密封环50。密封环50通过粘结或过盈配合的方式将玻璃盖板20固定在环形外框10上,起到密封防水的作用。
在一可实施方式中,密封环50为L形,L形密封环50包括竖直部和水平部,竖直部位于玻璃盖板20与环形外框10之间的承台12上方,水平部位于承台12与玻璃盖板20之间。由于密封环50不与触控线路板30接触,且装配稳定,不影响触控功能的实现。
在一可实施方式中,玻璃盖板20包括一层或多层玻璃。当玻璃盖板20为一层时,可以将该玻璃盖板20下端一体加工出与承台12配合的阶梯结构21;当玻璃盖板20或阶梯结构21为多层时,多层玻璃之间通过粘结胶层等进行连接,具体的,上端玻璃层直径较大用于搭设在承台12上,而与承台12配合的构成阶梯结构21的玻璃层则直径较小,以实现玻璃层侧面与承台12的稳定安装,并且配合触控线路板30安装。
在一可实施方式中,阶梯结构21包括圆环,触控线路板30设置在圆环下方。本发明实施例中,圆环可以为玻璃圆环或胶水圆环,圆环下设置有触控线路板30以实现触控功能。其中,圆环所围合的中间区域可以部分或全部填充导电胶;具体如当圆环外圈采用玻璃圆环时,内圈通过导电胶进行填充,这样使得圆环中间区域在填充有导电胶的位置上也能够实现触控功能。具体的,触控线路板30可以设置在整个玻璃盖板20及圆环下;也可以只设置圆环下的部分,仅在这一圆环区域可实现触控功能;还可以根据具体需求部分设置在玻璃盖板20其他区域,如部分设置在圆环围合的中间区域,部分设置在圆环下方,以实现具体区域的触控需求。
在一可实施方式中,圆环的外壁与承台12的侧面相配合。本发明实施例中,承台12为阶梯结构21和圆环相对应配合的台阶状,玻璃盖板20上端搭设在承台12的水平台面上,而圆环的外壁可以抵触连接在承台12的侧面,或通过粘接等方式与其进行连接,当然,圆环外壁与承台12侧面之间也可以留有空隙,只要能够实现稳定装配,且不影响触控功能即可。
在一可实施方式中,阶梯结构21包括第一厚度的粘结胶层,触控线路板30位于阶梯结构21下并与粘结胶层进行连接。具体的,粘结胶层的第一厚度可以根据具体需要进行设置,通过调节粘结胶层的第一厚度可以将触控线路板30及其连接的柔性线路40在垂直方向上下移,从而使阶梯结构21的底面低于凹槽11的顶面或与凹槽11的顶面齐平,进而设于阶梯结构21下的触控线路板30得以有富裕的空间从环形外框10的中间区域向凹槽11区域延伸布置,同样的,柔性线路40与阶梯结构21的连接区域也可以向凹槽11区域延伸,从而更有效的减少黑边,提升用户体验。
在一可实施方式中,阶梯结构21可以是其它形状,例如三角形、四边形等规则形状,也可以是非规则形状,阶梯结构21可以为一体的,也可以是由多个部分组成的,例如一半是半圆形玻璃,另一半是半圆环玻璃等等。阶梯结构21的底面可以是平整的,也可是倾斜或者不平整的。
在一可实施方式中,由于环形外框10的宽度自上向下逐渐增大,因此可以在环形外框10的下部设置凹槽11以获取更大的宽度空间,因为环形外框10下部宽度较大,将凹槽11设置在下部的这一方式,一方面不影响环形外框10的结构强度,另一方面给柔性线路40留出了足够的弯折区域,可以大大减小柔性线路40和触控线路板30的接触面积,即大大减小其接合区的面积。具体的,环形外框10的外侧壁可以呈弧形且宽度自上向下逐渐增大;也可以呈直线形且从上到下宽度逐渐增大,也即大体呈现一类梯形的结构,类梯形结构可以是梯形结构,也可以是跟梯形较为相似的结构,例如其中的一个或者多个边为曲线,由五条或者更多条线段或者曲线组成等等;当然环形外框10还可以为其他下宽上窄的具体形状,本发明实施例在此不一一列举。
且在一可实施方式中,凹槽11的宽度自上向下逐渐增大。那么便可以通过调节粘结胶层的厚度,或玻璃盖板20的厚度或层数等方式使触控线路板30和柔性线路40下移,以获得更充裕的凹槽11空间用于弯折,有助于大大减小柔性线路40和触控线路板30的接触面积,从而减少黑边宽度,提升用户体验。
在一可实施方式中,柔性线路40与凹槽11的顶面相连接。具体可以通过在凹槽11上设置安装构件来安装柔性线路40的方式,或者通过粘接等方式来将柔性线路40连接在凹槽11顶部,用于对柔性线路40进行线路导引和限位保护。
在一可实施方式中,凹槽11的侧壁上设有安装部,安装部用于对柔性线路40进行限位。具体的,安装部可以为限位槽,也可以为限位卡件等具体结构,还可以为预设安装柔性线路的部位,又或者为其他具体结构,本发明实施例在此不对安装部的具体结构进行列举,只要能够用于帮助安置柔性线路40使其不易发生位移影响稳固装配即可。
在一可实施方式中,柔性线路40与触控线路板30和/或阶梯结构21的底面相连接。具体可以通过粘接或其他方式进行连接。本发明实施例将柔性线路40与触控线路板30和/或阶梯结构21的底面相连接的区域确定为第一接合区60,将柔性线路40与凹槽11相连接的区域确定为第二接合区70。本发明实施例中,柔性线路40也可以同时与凹槽11进行连接,如连接在凹槽11的安装部上,这样,柔性线路40与触控线路板30和/或阶梯结构21的底面实现了第一接合区60的接合,柔性线路40与凹槽11实现了,这样的多区域接合能充分保证该装配结构的接合强度。另外,即使由于外力等因素造成了柔性线路40的运动,首先受到影响的也只是位于凹槽11中的柔性线路40,而其与触控线路板30的连接区域能够得以保证充分的稳定。在一可实施方式中,由于布线区31全部位于凹槽11内,该组合结构可以不具有第一接合区60的结合,而只有柔性线路40与凹槽11在安装部的接合。
本发明实施例另一方面提供一种可穿戴设备,包括上述实施例中任一实施方式的触控设备的组合结构。具体的,该可穿戴设备可以为手机、手表等可穿戴设备,当可穿戴设备为手机时,还包括处理器、电池以及通信模块等其他组成部分;而当可穿戴设备为手表时,还包括如电池、表带等装置。本可穿戴设备的组合结构具体可以参考上述实施例内容,本发明实施例在此不再重复阐述。
本发明实施例中,多个步骤之间的实现顺序在不影响实现目的的情况下可以替换。上述装置及计算机可读存储介质的具体实现技术手段及效果请参考方法实施例。
以上,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权利要求的保护范围为准。
