图2是本发明图1中A-A局部剖面图。
图3是本发明图2中触摸屏的剖面图。
图4是本发明中基于移动终端的嵌入式指纹识别装置较佳实施例的凹槽结构示意图。
 本发明的最佳实施方式
本发明提供一种基于移动终端的嵌入式指纹识别装置及其制造方法，为使本发明的目的、技术方案及效果更加清楚、明确，以下参照附图并举实例对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图1所示，本发明提供了一种基于移动终端的嵌入式指纹识别装置，其包括：触摸屏模组100及指纹识别模组200，其中，所述触摸屏模组100包括触摸屏110，如图2所示，所述触摸屏110开设有一凹槽300；所述指纹识别模组200嵌入式设置于所述凹槽300内，所述凹槽300如图4所示。
本发明较佳实施例中，所述触摸屏110指玻璃面板，其靠近移动终端一侧连接有触摸屏传感器120。所述凹槽300通过CNC即数控机床加工，或通过HF即氢氧化钠蚀刻而成，工艺简单且由于CNC加工及HF蚀刻技术较为成熟，可以保证凹槽300的加工精度，提高其精品率。
本发明所提供的基于移动终端的嵌入式指纹识别装置，由于采用了触摸屏模组100，所述触摸屏模组100包括触摸屏110，所述触摸屏110开设有一凹槽300；以及嵌入设置于所述凹槽300内的指纹识别模组200。使得指纹识别模组200可以直接凹入触摸屏110所设凹槽300，降低了其本体厚度对于移动终端厚度及长度的影响，且直接放置在凹槽300后固定，简单方便，解决了现有技术中指纹识别模组200厚度较厚、装配复杂，导致移动终端厚度及长度变大的问题。
进一步地，所述凹槽300包括：第一槽部310，如图4所示，设置于触摸屏110贴合移动终端一侧；所述指纹识别模组200包括：柔性电路板210，设置于所述第一槽部310内。
如图2所示，所述第一槽部310为所述柔性电路板210所在，因此，未在图中标示，所述柔性电路板210可通过点胶的方式固定于触摸屏110、且位于第一槽部310内，点胶粘接的方式不仅连接方便、稳定性强，且成本低。
进一步地，所述指纹识别模组200还包括：补强钢板220，与柔性电路板210相贴合，并对其进行补强、从而使其不易弯折。
所述补强钢板220与所述柔性电路板210贴合连接的同时，其边角通过点胶固定于所述触摸屏110，为其固定提供双重保障，进一步增强其连接稳定性。
本发明较佳实施例中，所述凹槽300还包括：第二槽部320，如图4所示，设置于触摸屏110背离移动终端一侧、且与所述第一槽部310连通；所述指纹识别模组200还包括：指纹识别传感器230，设置于所述第二槽部320内。
具体实施时，所述指纹识别传感器230仅与所述柔性电路板210连接即可，在柔性电路板210及补强钢板220连接稳定的基础上，足以保证其设置稳定性，该设置可进一步简化所述基于移动终端的嵌入式指纹识别装置的装配过程。
进一步地，所述触摸屏110设置有：第一斜棱部111，如图3所示，其使第一槽部310纵截面呈内长外短的梯形。
所述内长外短是相对于移动终端与所述基于移动终端的嵌入式指纹识别装置的位置描述，即若将移动终端横放，则第一槽部310在第一斜棱部111的作用下，横截面呈倒置的等腰梯形。
通过所述第一斜棱部111的设置，使得在点胶粘接柔性电路板210时，方便进行胶液处理。
进一步地，所述的基于移动终端的嵌入式指纹识别装置，其中，所述触摸屏110还设置有：第二斜棱部112，如图3所示，其使第二槽部320纵截面呈内长外短的梯形。
第二斜棱部112位置的设置及达到的效果与第一斜棱部111同理，但其功能与第一斜棱部111并不相同，其设置一方面可防止玻璃面板的棱角划伤用户或造成用户使用不舒适，另一方面可美化移动终端。
进一步地，所述的基于移动终端的嵌入式指纹识别装置，其中，所述触摸屏110还设置有：第三斜棱部113，如图3所示，其与第二斜棱部112横向对称设置。
进一步地，所述的基于移动终端的嵌入式指纹识别装置，其中，所述第二斜棱部112通过丝印或电镀为可实现立体显示效果的颜色。
具体实施时，可将所述第二斜棱部112处理为银色，现有技术中通常使用指纹识别金属装饰环，而本发明可直接取消指纹识别金属装饰环，而改用在第二槽部320上边缘曲面即第二斜棱部112丝印/转移/电镀装饰圈，从而实现3D装饰环的显示效果。
一种如上任意一项所述基于移动终端的嵌入式指纹识别装置的制造方法，其中，所述凹槽300通过对触摸屏进行CNC加工或蚀刻加工得到，具体如上述装置实施例所述。
应当理解的是，本发明的应用不限于上述的举例，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，所有这些改进和变换都应属于本发明所附权利要求的保护范围。
