本申请要求于2017年4月6日递交的发明名称为“一种前置指纹器件和电子设备”、申请号为201710222046.1的中国专利申请的优先权，其全部内容以引入的方式并入本申请中。
技术领域
本申请涉及通讯设备技术领域，尤其涉及一种指纹识别组件以及一种应用所述指纹识别组件的终端。
背景技术
随着消费者对智能终端设备的轻薄、大屏占比、多功能化等需求的发展，终端设备内部的零部件堆叠布局空间也日趋紧凑。现有终端的正面通常布置有液晶显示模组和指纹识别模组。为了保证终端的屏占比，液晶显示模组与指纹识别模组的空间排布非常靠近彼此甚至发生重叠。由于液晶显示模组通常先组装在盖板背面，因此在后续的将指纹识别模组组装到盖板背面的过程中，容易因空间不足而导致组装困难。
发明内容
本申请实施例提供一种在组装难度较小的指纹识别组件及终端。
为了实现上述目的，本申请实施方式采用如下技术方案：
一方面，本申请实施例提供一种指纹识别组件，所述指纹识别组件包括指纹识别模组和固定支架。所述指纹识别模组包括相对设置的触摸侧和非触摸侧。所述触摸侧设置有限位块。所述固定支架包括连接部及设于所述连接部相对两侧的支撑部，所述连接部用于连接至所述非触摸侧，以使所述指纹识别组件组装至待组装件时，所述限位块卡在所述待组装件外侧且所述支撑部抵触在所述待组装件内侧。所述待组装件外侧与所述待组装件内侧为所述待组装件的相对两侧。
一种实施方式中，所述待组装件上设有组装孔，所述组装孔在所述待组装件外侧向所述待组装件内侧的方向上贯穿所述待组装件。为方便后文说明，将所述待组装件外侧向所述待组装件内侧的方向定义为第一方向，将所述待组装件内侧向所述待组装件外侧的方向定义为第二方向，所述第一方向和所述第二方向统称为所述待组装件的厚度方向。所述待组装件外侧设置有定位面，所述定位面设于所述组装孔周边，所述定位面可连接所述组装孔孔壁设置。将所述指纹识别组件组装至所述待组装件时，所述指纹识别模组自所述待组装件外侧伸入所述组装孔，所述限位块抵触所述定位面时，所述定位面阻止所述指纹识别模组继续向第一方向移动，使得所述指纹识别模组的所述触摸侧相对固定在所述待组装件外侧。然后，紧密连接所述指纹识别模组的所述非触摸侧与所述固定支架的连接部，使得所述固定支架的所述支撑部抵触所述待组装件内侧，从而阻止所述指纹识别模组向所述第二方向移动，使得所述指纹识别模组的所述非触摸侧相对固定在所述待组装件内侧。此时，所述指纹识别组件与所述待组装件彼此固定。
在本实施方式中，由于所述指纹识别组件包括所述指纹识别模组和所述固定支架两部分，所述指纹识别组件可以在与所述待组装件组装时，分别从所述待组装件的内、外两个方向组装和固定所述固定支架和所述指纹识别模组，并且通过所述待组装件内侧和所述待组装件外侧共同固定所述指纹识别组件，因此降低了所述指纹识别组件组装至所述待组装件时的空间需求，降低了所述指纹识别组件的组装难度，所述指纹识别模组的组装难度较小。相较于现有技术中，指纹识别模组因需要在待组装件的一侧实现固定而导致指纹识别模组整体体积较大，本申请实施例所述指纹识别组件由于从所述待组装件两侧实现固定，因此能够简化所述指纹识别组件的支架结构以降低所述指纹识别组件的整体厚度，进一步降低所述指纹识别组件所需占用的空间(例如所述待组装件的厚度方向上的空间)，使得所述终端内部构件的排布更为灵活，有利于所述终端的轻薄化。

所述指纹识别组件2包括指纹识别模组21和固定支架22。所述指纹识别模组21包括相对设置的触摸侧211和非触摸侧212。所述触摸侧211设置有限位块213。所述固定支架22包括连接部221及设于所述连接部221相对两侧的两个支撑部222(一种实施方式中，设于所述连接部221相对两侧的两个支撑部222也可以连接成为一体，即包围或半包围连接部221的支撑部222结构)，所述连接部221用于连接至所述非触摸侧212，以使所述指纹识别组件2组装至待组装件1时，所述限位块213卡在所述待组装件1外侧11且所述支撑部222抵触在所述待组装件1内侧12。所述待组装件1外侧11与所述待组装件1内侧12为所述待组装件1的相对两侧。
举例而言，所述待组装件1上设有组装孔13，所述组装孔13在所述待组装件1外侧11向所述待组装件1内侧12的方向上贯穿所述待组装件1。为方便后文说明，将所述待组装件1外侧11向所述待组装件1内侧12的方向定义为第一方向X，将所述待组装件1内侧12向所述待组装件1外侧11的方向定义为第二方向Y，所述第一方向X和所述第二方向Y统称为所述待组装件1的厚度方向。所述待组装件1外侧11设置有定位面14，所述定位面14设于所述组装孔13周边，所述定位面14可连接所述组装孔13孔壁设置。将所述指纹识别组件2组装至所述待组装件1时，所述指纹识别模组21自所述待组装件1外侧11伸入所述组装孔13，所述限位块213抵触所述定位面14时，所述定位面14阻止所述指纹识别模组21继续向第一方向X移动，使得所述指纹识别模组21的所述触摸侧211相对固定在所述待组装件1外侧11。然后，紧密连接所述指纹识别模组21的所述非触摸侧212与所述固定支架22的连接部221，使得所述固定支架22的所述支撑部222抵触所述待组装件1内侧12，从而阻止所述指纹识别模组21向所述第二方向Y移动，使得所述指纹识别模组21的所述非触摸侧212相对固定在所述待组装件1内侧12。此时，所述指纹识别组件2与所述待组装件1彼此固定。
在本实施例中，由于所述指纹识别组件2包括所述指纹识别模组21和所述固定支架22，所述指纹识别组件2可以在与所述待组装件1组装时，分别从所述待组装件1的内、外两个方向组装和固定所述固定支架22和所述指纹识别模组21，并且通过所述待组装件1内侧12和所述待组装件1外侧11共同固定所述指纹识别组件2，因此降低了所述指纹识别组件2组装至所述待组装件1时的空间需求，降低了所述指纹识别组件2的组装难度，所述指纹识别模组21的组装难度较小。相较于现有技术中，指纹识别组件2因需要在待组装件1的一侧实现固定而导致指纹识别组件2整体体积较大，本申请实施例所述指纹识别组件2由于从所述待组装件1两侧实现固定，因此能够简化所述指纹识别组件2的支架结构以降低所述指纹识别组件2的整体厚度，进一步降低所述指纹识别组件2所需占用的空间(例如所述待组装件1的厚度方向上的空间)，使得所述终端100内部构件的排布更为灵活，有利于所述终端100的轻薄化。
可选的，支撑部222的数量为两个，分别位于连接部221相对的两侧，且所述支撑部222与所述连接部221一体成型。在所述终端100的宽度方向上，所述固定支架22可大致呈“凹”形。

在本实施例中，由于所述指纹识别组件2通过所述限位块213和所述支撑部222实现与所述待组装件1的彼此固定，因此所述装饰件214的结构设计设置所受到的限制较小，所述第一侧壁2144的高度可以与所述第二侧壁2145的高度不同，使得所述指纹识别组件2周边的部件排布更为灵活，所述终端100内部的部件布局更为紧凑，有利于所述终端100的轻薄化。
请一并参阅图1至图9，作为一种可选实施例，如图3C所示，所述限位块213呈环形状。此时，所述待组装件1的所述定位面14也可沿环形的轨迹延伸，从而与所述限位块213实现更好的配合。在一种实施方式中，所述限位块213为连续的环形结构。如图3D所示，在另一种实施方式中，所述限位块213为间隔设置的多个块体，所述多个块体沿环形轨迹排布。
可选的，所述限位块213相对其周边呈外凸结构，相应地，所述定位面14相对其周边呈内凹结构，限位块213和定位面14之间形成凹凸配合，以增加限位的稳固性。
可选的，所述限位块213具有用于接触所述待组装件1的限位面2131。所述限位面2131与所述定位面14相配合，以实现所述指纹识别模组21与所述待组装件1的彼此定位。所述指纹识别组件2具有设于所述触摸侧211的触摸表面2111，一种实施方式中，所述限位面2131相对所述触摸表面2111倾斜，如图3A和图3B中所示，限位面2131和触摸表面2111相交。所述限位面2131与所述触摸表面2111相交时，所述限位块213的横截面形状大致为三角形，此时所述定位面14可通过倒角工艺形成。
限位块213的限位面3121的形状可以有多种选择，限位块213的横截面可以为矩形、三角形、梯形或其它形状，只要能卡在定位面14即可，相应地，定位面14的形状与限位面3121的形状相匹配。如图3E，示意性地表达了几种不同形状的限位面3121的结构。
一种实施方式中，所述限位面2131与所述触摸表面2111也可以大致平行，所述限位块213的横截面形状大致为矩形，即形成台阶状限位结构。
所述限位面2131可以为平面，也可以为曲面。所述定位面14的形状与所述限位面2131的形状相适配。
请一并参阅图1至图11，作为一种可选实施例，所述固定支架22的所述支撑部222弹性抵接所述待组装件1内侧12。
在一种实施方式中，所述固定支架22采用具有弹性的材料，例如弹簧钢。所述固定支架22的所述连接部221连接所述指纹识别模组21的所述非触摸侧212时，所述支撑部222抵接所述待组装件1内侧12后发生形变，形变产生反向弹性力，从而使所述固定支架22往所述第一方向X拉紧所述指纹识别模组21。
在另一种实施方式中，所述支撑部222上设有弹性件24，所述弹性件24弹性连接在所述 支撑部222与所述待组装件1之间。所述弹性件24可采用橡胶材料。所述固定支架22的所述连接部221连接所述指纹识别模组21的所述非触摸侧212时，所述弹性件24被挤压在所述支撑部222与所述待组装件1内侧12之间，所述弹性件24发生形变而产生反向弹性力，从而使所述固定支架22往所述第一方向X拉紧所述指纹识别模组21。
所述弹性件24包括固定部241和抵触部242。所述固定部241固定连接(例如通过第三粘接层243粘接)所述支撑部222。所述抵触部242设于所述固定部241远离所述支撑部222的一侧。所述抵触部242与所述待组装件1内侧12的连接关系为可拆卸地抵接，两者之间不粘接。
所述抵触部242设有镂空区域以增加弹性形变能力。例如，所述抵触部242可为环形结构，所述抵触部242中间区域镂空。
可以理解的，如图11所示，由于所述柔性电路板218的走线需求，所述柔性电路板218也可经过所述支撑部222与所述待组装件1内侧12之间的区域。此时，所述支撑部222或所述弹性件24抵接所述柔性电路板218，所述柔性电路板218朝向所述待组装件1内侧12的一侧设置有补强板或保护膜片2185，以保护所述柔性电路板218。
请一并参阅图1至图12，作为一种可选实施例，所述终端100还包括显示器组件3。所述显示器组件3固定于所述待组装件1内侧12。所述显示器组件3包括触摸显示器，所述显示器可为液晶显示器(Liquid Crystal Display，LCD)。所述显示器组件3可与所述待组装件1先形成一体化结构，然后再将所述指纹识别组件2组装至所述待组装件1。
在本实施例中，由于所述指纹识别组件2在与所述待组装件1组装时，分别从所述待组装件1的内、外两个方向组装和固定所述固定支架22和所述指纹识别模组21，所述指纹识别组件2组装所需要的空间较小且组装难度较小，因此可降低划伤所述显示器组件3的可能性。同时，由于所述指纹识别组件2的组装步骤靠后，因此如果所述指纹识别模组21发生损坏问题，可直接更换所述指纹识别模组21，无需同时拆卸所述显示器组件3，所述指纹识别模组21易拆卸返工，从而降低了所述终端100的组装和维修成本。
可选的，所述指纹识别组件2在所述待组装件1上的正投影与所述显示器组件3在所述待组装件1上的正投影部分重叠。此时，所述装饰件214的所述第一侧壁2144的高度可低于所述第二侧壁2145的高度，所述第一侧壁2144靠近所述显示器组件3设置，所述第一侧壁2144在所述待组装件1上的正投影与所述显示器组件3在所述待组装件1上的正投影部分重叠。
在本实施例中，所述指纹识别组件2与所述显示器组件3在所述待组装件1上的正投影部分重叠，所述指纹识别组件2与所述显示器组件3之间的距离很近，使得所述终端100内的部件排布更为紧凑，有利于所述终端100的轻薄化。同时，也使得所述指纹识别模组21的所述触摸侧211大致位于所述终端100正面的非现实区域的中间位置，使所述终端100的用户体验更好。
可选的，所述终端100还包括壳体4和主板5。所述待组装件1固定于所述壳体4，所述固定支架22和所述主板5收容于所述壳体4内部。所述固定支架22电连接至所述主板5的接地电极51，使得所述固定支架22接地。所述指纹识别模组21可通过所述连接器25连接至所述主板5，以实现通讯。
在一种实施方式中，所述壳体4包括金属中框41。所述固定支架22通过导电泡棉6电连接所述金属中框41，所述金属中框41通过导电弹片7电连接所述接地电极51。此时，所述装 饰件214、所述补强板2181、所述连接片215以及所述固定支架22均接地设置。
以上所述，仅为本发明的具体实施方式，但本发明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发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。
