背景技术
目前手机的正面常设有指纹识别模组和显示屏，并将指纹识别模组与显示屏相叠合以增加手机的屏占比。同时，采用柔性显示屏形成可折叠的移动终端，以实现大屏化显示。然而，由于柔性显示屏不能承受外部压力，因此采用整面贴合方式将指纹识别模组直接固定在柔性显示屏上时，柔性显示屏容易起褶皱，光线经过柔性显示屏时光路被改变，从而导致指纹识别模组指纹识别准确度低。
发明内容
本申请所要解决的技术问题在于提供一种壳体，安装于所述壳体内的指纹识别模组的识别准确度高。
此外，还提供一种应用所述壳体的移动终端。

具体实施方式
下面结合附图，对本申请的实施例进行描述。
请一并参阅图1至图4，本申请实施例提供一种移动终端100。所述移动终端100可以是手机、平板电脑、或笔记本电脑等。
所述移动终端100包括柔性显示屏1、指纹识别模组2及壳体3。所述壳体3的顶面31用于承载所述柔性显示屏1。所述壳体3设有连接所述顶面31的安装槽32，所述安装槽32用于收容所述指纹识别模组2。所述安装槽32具有槽底壁321和连接在所述槽底壁321四周与所述顶面31之间的槽侧壁322。所述柔性显示屏1贴合于所述顶面31，所述指纹识别模组2收容于所述安装槽32，使得所述指纹识别模组2位于所述柔性显示屏1与所述壳体3之间。
在本实施例中，组装所述移动终端100时，可先将所述指纹识别模组2装入所述壳体3的所述安装槽32内，然后在所述壳体3的顶面31上铺设所述柔性显示屏1，使得所述指纹识别模组2位于所述柔性显示屏1与所述壳体3之间，所述指纹识别模组2位于所述柔性显示屏1的下方，光线穿过所述柔性显示屏1进入所述指纹识别模组2后，所述指纹识别模组2能够识别接触所述柔性显示屏1的用户指纹。
由于所述移动终端100借助所述壳体3实现所述指纹识别模组2与所述柔性显示屏1之间的彼此定位和固定，在所述移动终端100的组装过程中，所述柔性显示屏1可直接铺设在所述顶面31上，无需承受来自所述指纹识别模组2的压力，因此能够避免所述柔性显示屏1起褶皱，使得所述柔性显示屏1保持平整，光线能够保持原始光路穿过所述柔性显示屏1并进入所述指纹识别模组2，使得 所述指纹识别模组2的指纹识别准确度较高。
如图1所示，在一种实施方式中，所述壳体3包括与所述顶面31相对设置的底面。所述柔性显示屏1包括固定部11和自由部12。所述固定部11贴合所述顶面31，所述自由部12弯折接触所述底面或收容于所述壳体3内部。此时，所述指纹识别模组2位于所述固定部11的下方。
所述自由部12收容于所述壳体3内部时，所述壳体3上设有与所述顶面31间隔设置的收容腔。所述收容腔的开口位于所述顶面31和所述底面之间。
如图4所示，在另一种实施方式中，所述壳体3包括第一本体35、第二本体33以及弯折组件34。所述第一本体35具有用于安装所述柔性显示屏1的第一安装表面351。所述第二本体33具有用于安装所述柔性显示屏1的第二安装表面331。所述弯折组件34连接在所述第一本体35与所述第二本体33之间，所述弯折组件34具有用于安装所述柔性显示屏1的第三安装表面341。所述弯折组件34使得所述第一本体35可相对所述第二本体33折叠或展开。
此时，所述第一安装表面351、所述第二安装表面331以及所述第三安装表面341共同构成所述壳体3的所述顶面31。所述安装槽32可设于所述第一本体35并连接所述第一安装表面351和/或设于所述第二本体33并连接所述第二安装表面331，使得所述指纹识别模组2置于所述第一本体35和/或所述第二本体33内。
可选的，所述柔性显示屏1为可弯折的显示面板。所述柔性显示屏1可为触控屏，以同时实现显示和触控功能。所述柔性显示屏1可为OLED(Organic Light-Emitting Diode，有机激光显示)显示面板。所述指纹识别模组2用于通过光线识别用户指纹。所述指纹识别模组2所识别的光线可由其自身发出，穿过所述柔性显示屏1后被用户手指反射，或者由柔性显示屏1发出后被用户手指反射，发射光线穿过所述柔性显示屏1后进入所述指纹识别模组2。
作为一种可选实施例，请一并参阅图1至图3，所述指纹识别模组2贴合于所述安装槽32的槽底壁321。所述指纹识别模组2可粘接所述槽底壁321。
可以理解的是，所述柔性显示屏1贴合所述顶面31，因此所述柔性显示屏1大致平行于所述顶面31。所述指纹识别模组2的信号采集面与所述指纹识别模组2的贴合于所述槽底壁321的表面之间形成一定的相对位置关系，例如平行或形成预定夹角等，本申请实施例以两者平行为例进行说明。
可选的，所述槽底壁321平行于所述顶面31或与所述顶面31之间形成小于等于5°的夹角。
在本实施例中，通过对所述槽底壁321与所述顶面31之间位置关系的限定，实现对所述柔性显示屏1与所述指纹识别模组2的所述信号采集面之间位置关系的限定。当所述信号采集面大致平行于所述柔性显示屏1或与所述柔性显示屏1之间形成微小夹角时，所述信号采集面能够更好地采集穿过所述柔性显示屏1的光线，因此所述指纹识别模组2具有更高的识别准确度。
可选的，所述安装槽32的深度大于所述指纹识别模组2的厚度。此时，所述指纹识别模组2不仅能够完全收容于所述安装槽32，并且所述指纹识别模组2与所述柔性显示屏1之间形成间隙，两者之间保持一定间距，从而能够降低所述柔性显示屏1贴合于所述顶面31的工艺难度，提高贴合质量，使得所述移动终端100的产品良率较高，所述指纹识别模组2的识别精度较高。
举例而言，所述安装槽32的深度比所述指纹识别模组2的厚度大至少0.1mm(毫米)，使得所述指纹识别模组2与所述柔性显示屏1之间的间距大于等于0.1mm。换言之，所述安装槽32的深度与所述指纹识别模组2的厚度之间的差值大于等于0.1mm。
进一步地，所述间距可大于等于0.15mm且小于等于0.25mm，例如所述间距可为0.2mm。换言之，所述差值大于等于0.15mm且小于等于0.25mm。
作为一种可选实施例，请一并参阅图1及图5至图7，所述安装槽32的槽侧壁322上形成限位面323，所述指纹识别模组2朝向所述柔性显示屏1的表面接触所述限位面323。
在本实施例中，所述限位面323用于在所述柔性显示屏1的出光方向上对所述指纹识别模组2的位置进行限制，从而能够通过对所述限位面323的设置，使得所述指纹识别模组2与所述柔性显示屏1之间具有合适的相对位置关系，进一步提高所述指纹识别模组2的识别准确度。
可以理解的是，所述柔性显示屏1贴合所述顶面31，因此所述柔性显示屏1大致平行于所述顶面31。所述指纹识别模组2的信号采集面与所述指纹识别模组2朝向所述柔性显示屏1的表面之间形成一定的相对位置关系，例如共面、平行或形成预定夹角等，本申请实施例以两者共面为例进行说明。
可选的，所述限位面323平行于所述顶面31或与所述顶面31之间形成小于 等于5°的夹角。
在本实施例中，通过对所述限位面323与所述顶面31之间位置关系的限定，实现对所述柔性显示屏1与所述指纹识别模组2的所述信号采集面之间位置关系的限定。当所述信号采集面大致平行于所述柔性显示屏1或与所述柔性显示屏1之间形成微小夹角时，所述信号采集面能够更好地采集穿过所述柔性显示屏1的光线，因此所述指纹识别模组2具有更高的识别准确度。
可选的，所述限位面323与所述顶面31之间形成大于等于0.1mm的间距，使得所述指纹识别模组2与所述柔性显示屏1之间存在大于等于0.1mm的间距，从而降低所述顶面31贴合所述柔性显示屏1的工艺难度，提高贴合质量，使得所述显示装置的产品良率较高，所述指纹识别模组2的识别精度较高。
可选的，所述顶面31与所述限位面323之间形成过渡弧面324，用于方便将所述指纹识别模组2装入所述安装槽32。此时，所述过渡弧面324与所述限位面323共同围设出凸出于槽侧壁322的限位块325。
在本实施例中，所述限位块325在外力作用下具有一定的形变能力，通过外力使所述限位块325发生变形，将所述指纹识别模组2装入所述安装槽32后，撤去所述外力，则所述限位块325恢复原状。所述过渡弧面324的设置有利于降低所述指纹识别模组2的组装难度。
可选的，所述安装槽32的槽底壁321上设有压紧件36。所述压紧件36在外力作用下发生形变。所述压紧件36用于将所述指纹识别模组2压紧在所述限位面323上。此时，所述槽底壁321、所述压紧件36以及所述限位面323之间相互配合，能够更好地对所述指纹识别模组2进行限位。同时，所述压紧件36可吸收一部分的工艺公差，从而降低所述指纹识别模组2的组装难度。
具体而言，所述压紧件36为弹性件，例如弹簧、泡棉、橡胶等。当然，在其他实施方式中，所述压紧件36也可为柔性件，所述压紧件36能够配合压紧所述指纹识别模组2即可。
作为一种可选实施例，请一并参阅图2、图3以及图5至图7，所述槽侧壁322上设有多个凸起37。所述多个凸起37间隔地分布在所述安装槽32的四周，用于同时接触所述指纹识别模组2的四周，以对所述指纹识别模组2进行限位。所述多个凸起37在垂直于所述柔性显示屏1的出光方向的平面上，对所述指纹识别模组2进行全方位的限位，使得所述壳体3能够更好地定位和固定所述指纹识别 模组2。
作为一种可选实施例，请一并参阅图2、图3以及图5，所述壳体3内设有收容空间38，所述收容空间38与所述顶面31及所述安装槽32间隔设置，所述收容空间38用于收容所述移动终端100的主板4。所述收容空间38可同时收容所述移动终端100的电池5。
所述柔性显示屏1及所述指纹识别模组2均电连接至所述主板4。所述主板4控制所述柔性显示屏1进行显示(和触控识别)。所述指纹识别模组2将采集到的用户指纹发送至所述主板4。
可选的，所述壳体3设有走线通道39，所述走线通道39连通所述安装槽32和所述收容空间38。此时，所述指纹识别模组2的柔性电路板可通过所述走线通道39连接至所述主板4，从而实现所述指纹识别模组2与所述主板4之间的电连接。
当然，在其他实施方式中，所述壳体3也可不设所述走线通道39，所述指纹识别模组2与所述主板4之间通过无线连接方式实现电连接。
以上对本申请实施例进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
