Description

一种电池盖以及电子设备 技术领域
本发明实施例涉及电子设备领域，尤其涉及一种电池盖以及电子设备。
背景技术
随着科技的发展，终端(例如，手机、平板电脑)越来越普及，并成为现代人生活中不可或缺的工具。电池盖作为终端中必不可少的一部分，通常用于与终端的壳体扣合，将终端的电池以及终端内部的器件(例如，摄像头，闪光灯组件)包裹在终端内。目前市场上，终端的电池盖大多采用玻璃材质。
现有技术中提供一种电池盖，如图1A所示，该电池盖10包括玻璃基板101，在该玻璃基板101上与终端摄像头相对的位置设置有用于形成摄像头区域的摄像头通孔102。如图1B所示，该摄像头区域包括用于保护终端摄像头20及提高摄像头光学性能的摄像头镜片104以及用于支撑摄像头镜片104的摄像头装饰件103，该摄像头镜片104镶嵌于摄像头装饰件103内，为了减小摄像头镜片104与摄像头通孔102之间的间隙，通常采用双面背胶粘胶、点胶或点焊的方式将摄像头装饰件103固定在摄像头通孔102内。
在加工电池盖时，若涂抹的背胶粘胶、点胶比较薄，或者摄像头装饰件103粘贴不平整，均可能导致摄像头镜片104与电池盖10之间存在缝隙，这样很容易导致粉尘或者液体进入终端内部，污染了终端的摄像头20；此外，由于摄像头本身高度以及整机厚度限制，为达到摄像头20拍摄的标准，因此必须在摄像头外设置摄像头镜片104，该摄像头镜片104不仅需要满足所需要的平面度来防止所拍摄的图片变形，且需要满足一定的透过率防止所拍摄的图片失真，同时还应该具有防刮性能等，且随着终端越来越轻薄化，摄像头镜片104及其摄像头装饰件103 均凸出上述电池盖，在用户使用过程中难免会出现磨损或刮花摄像头镜片104的情况，而且由于摄像头装饰件103仅依靠背胶或点胶或点焊的方式固定在电池盖10上，长期的磨擦会降低摄像头装饰件103的拉拔力，从而导致摄像头装饰件103以及摄像头镜片104脱落的现象。同时，上述电池盖在加工时，摄像头装饰件103和摄像头镜片104是分开制作的，这样不仅会增加工序，而且还会增加加工成本。
发明内容
本发明实施例提供一种电池盖以及电子设备，用以至少解决液体或者灰尘通过摄像头通孔进入电子设备内部的问题。
第一方面，本发明实施例提供一种电池盖，应用于电子设备中，用于与电子设备的壳体连接，包括玻璃基板，在玻璃基板的第一面设置有不透光层；在不透光层上开设有至少一个第一通孔，第一通孔与设置在所述电子设备内的摄像头组件相对设置；在玻璃基板的第一面设置有摄像头区域，该摄像头区域与至少一个第一通孔相对设置，在玻璃基板的摄像头区域设置有用于增加光线透过率的镀膜层，该摄像头区域的面积大于等于所述第一通孔的面积。
本发明实施例通过上述方案，由于为了提高摄像头组件的拍照效果，本发明实施例仅在不透光层上开设第一通孔，而玻璃基板上不需要开设与摄像头组件相对的通孔，这样当该电池盖应用于电子设备中时，可以有效防止灰尘、或者液体进入电子设备内部，同时由于在上述方案中，该玻璃基板上的摄像头区域的平面度能够满足预设平面度要求，因此能够防止摄像头组件所拍摄的图片变形，且在玻璃基板的摄像头区域设置有镀膜层，由于该镀膜层能够保证光线透过率，因此，本发明实施例提供的电池盖能够在不采用摄像头镜片的情况下，保证透过率及达到预设平面度要求，且减少整机组装工序，提供组装效率，此外，由于在玻璃基板上无需开设安装摄像头镜片的通孔，这样提高了上述电池盖整体强度。
可选的，上述不透光层包括炫光膜片或者丝印在玻璃基板的第一面的油墨层，这样可以增强玻璃基板的效果及提高上述电池盖的外观炫丽程度。
可选的，在不透光层上开设有第二通孔，该第二通孔与所述电子设备的闪光灯组件相对设置；在上述玻璃基板上开设有与第二通孔相对设置的通孔。由于玻璃基板具有导光作用，这样当闪光灯组件发光时，经过玻璃基板容易串光，因此，通过开设第二通孔以及与第二通孔相对设置的通孔可以避免串光。
可选的，在不透光层上开设有第三通孔，该第三通孔与电子设备的闪光灯组件相对设置；在玻璃基板的第一面设置有闪光灯区域，该闪光灯区域与第三通孔相对设置，在闪光灯区域设置有第二镀膜层，该闪光灯区域的面积大于等于第三通孔的面积。由于闪光灯区域设置有第二镀膜层，且该闪光灯区域的面积大于等于第三通孔的面积，这样不仅避免了闪光灯组件串光，且第三通孔仅开设在不透光层上，提高了电池盖整体强度。
可选的，在玻璃基板的第一面或第二面丝印有至少一个摄像头黑圈，一个摄像头黑圈与一个第一通孔相对设置，这样可以遮挡由于在不透光层上开设第一通孔产生的残胶不良和切割锯齿的问题。
可选的，摄像头黑圈的内径小于等于与摄像头黑圈相对设置的所述第一通孔直径。
可选的，在玻璃基板的第一面或第二面设置有至少一个标识部，该标识部，用于标识安装在电子设备内部的器件的位置或该器件采集信号的范围。这样一来，通过设置标识部，使得用户能够准确地知晓器件的安装位置，并在将该电池盖与壳体连接时，不易装反。
可选的，当上述器件为用于采集用户生命体征参数的采集装置时；该玻璃基板的第一面或第二面包括第一标识部，用于标识采集装置采集用户生命体征信号的范围；在不透光层上开设有第四通孔，该第四通孔与第一标识部相对设置，用于使得上述采集装置透过第四通孔与玻璃基板的第一面接触。
可选的，上述镀膜层为减反射膜，通过设置减反射膜能够提高透光率。
可选的，在玻璃基板的第二面设置有用于防指纹及油污的第二镀膜层，该第二镀膜层采用AF(anti-fingerprint，抗指纹)镀膜，这样可以 有效地防指纹，且容易擦拭掉产生在电池盖上的脏污。
第二方面，本发明实施例提供一种电子设备，该电子设备包括壳体、设置于所述壳体内的印制电路板PCB板以及第一方面至第一方面的任意一种可能的实现方式所提供的电池盖，其中，该电池盖与壳体连接，壳体内设置有与PCB板连接的摄像头组件；当电池盖与壳体连接时，摄像头组件与所述电池盖上的所述摄像头区域相对设置，电池盖的不透光层靠近所述PCB板。
可选的，该电子设备还包括：闪光灯组件，与PCB板连接；电池盖上还设置有闪光灯保护罩；当电池盖与壳体连接时，闪光灯组件可嵌入设置在所述闪光灯保护罩的容纳腔内。
可选的，该电子设备还包括：辅助对焦装置，设置于上述PCB板上，用于测量及识别被拍摄物体的距离，以实现摄像头组件的快速对焦；该玻璃基板的第一面或第二面包括第二标识部，该第二标识部用于标识所述辅助对焦装置的位置，当电池盖与上述壳体连接时，该辅助对焦装置与第二标识部相对设置。
可选的，在玻璃基板的第一面上与第二标识部相对的位置丝印有透光油墨，该透光油墨用于增加辅助对焦装置所发射和接受激光所在波段的透光率。
可选的，该电子设备还包括：采集装置，与PCB板连接，用于采集用户触摸所述第一标识部时产生的生命体征信号；当电池盖与上述壳体连接时，采集装置与设置在所述电池盖上的所述第一标识部相对设置。
本发明实施例通过上述方案，由于为了达到摄像头组件的拍摄效果，本发明实施例仅在设置在玻璃基板第一面的不透光层上开设第一通孔，而玻璃基板上不需要开设与摄像头组件相对的通孔，这样当该电池盖应用于电子设备中时，可以有效防止灰尘、或者液体进入电子设备内部，同时由于在上述方案中，该玻璃基板上的摄像头区域的平面度能够满足预设平面度要求，因此能够防止摄像头组件所拍摄的图片变形，且在玻璃基板的摄像头区域设置有镀膜层，由于该镀膜层能够保证光线透过率，因此，本发明实施例提供的电池盖能够在不采用摄像头镜片的情况下，保证透过率及达到预设平面度要求，且减少整机组装工序，提供 组装效率，此外，由于在玻璃基板上无需开设安装摄像头镜片的通孔，这样提高了上述电池盖整体强度。

需要说明的是，本发明实施例中的相对设置应至少保证一个器件A的中心与另一个器件B的中心正对。
如图2A和2B所示，本发明实施例提供一种电池盖201，应用于电子设备中，用于与电子设备的壳体连接，该电池盖201包括玻璃基板201B，在该玻璃基板201B的第一面设置有不透光层201A；在该不透光 层201A上开设有至少一个第一通孔20111，该第一通孔20111与设置在电子设备内的摄像头组件相对设置；
在玻璃基板201B的第一面设置有摄像头区域2011，该摄像头区域2011与该第一通孔20111相对设置，在玻璃基板201B的摄像头区域2011设置有用于增加光线透过率的镀膜层，摄像头区域的面积大于等于所述第一通孔的面积。
玻璃基板201B的摄像头区域2011为对玻璃基板第一面进行光学处理的区域，该摄像头区域2011需要满足明面度、透光率等的光学要求。
本发明实施例通过上述方案，为了达到摄像头组件的拍照效果，本发明实施例在玻璃基板第一面的不透光层上开设第一通孔，而玻璃基板上不需要开设与摄像头组件相对的通孔，这样当该电池盖应用于电子设备中时，可以有效防止灰尘、或者液体进入电子设备内部，同时由于在上述方案中，该玻璃基板上的摄像头区域的平面度能够满足预设平面度要求，因此能够防止摄像头组件所拍摄的图片变形，且在玻璃基板的摄像头区域设置有镀膜层，由于该镀膜层能够保证光线透过率，因此，本发明实施例提供的电池盖能够在不采用摄像头镜片的情况下，保证透过率及达到预设平面度要求，且减少整机组装工序，提供组装效率，此外，由于在玻璃基板上无需开设安装摄像头镜片的通孔，这样提高了上述电池盖整体强度。
本发明实施例中的电子设备可以指代所有带摄像头组件以及电池盖的电子设备，且该摄像头组件为该电子设备的后置摄像头组件。示例性的，该电子设备可以为平板电脑、手机、MP4等。
其中，本发明实施例中的玻璃基板采用透明玻璃基板。
可选的，该摄像头区域2011的平面度满足预设平面度要求，本发明实施例可以采用研磨工艺，使得摄像头区域的平面度满足预设平面度要求，本发明实施例对该预设平面度不进行限定，只要该预设平面度能够防止上述摄像头组件拍摄的图像变形即可，示例性的，该预设平面度可以为3微米。
可选的，本发明实施例在玻璃基板的第二面设置有用于防指纹及油污的第二镀膜层，该第二镀膜层采用AF(anti-fingerprint，抗指纹)镀 膜，这样可以有效地防指纹，且容易擦拭掉产生在电池盖上的脏污。
本发明实施例对玻璃基板201B的第一面和第二面不进行限定，可以理解的是，本发明实施例中的玻璃基板201B的第一面是与电子设备内部器件相对的一面，也即当上述电池盖与电子设备连接时，该设置在玻璃基板201B第一面的不透光层与电子设备内部器件相对。
可选的，本发明实施例中的不透光层包括炫光膜片或者丝印在玻璃基板第一面的油墨层。其中，炫光膜片可以贴合在玻璃基板的第一面，这样可以增强玻璃基板的外观效果，从而提高上述电池盖的外观炫丽程度。
具体的，本发明实施例中的炫光膜片201A可以通过OCA(Optically Clear Adhesive)光学胶贴合在玻璃基板201B的第一面，该炫光膜片的形状和尺寸与上述玻璃基板201B的形状和尺寸匹配。
如图2C所示，在本发明实施例中上述炫光膜片包括依次设置的OCA光学胶201A1、PET(polyethylene terephthalate，聚对苯二甲酸乙二醇酯)膜片201A2、NCVM(Nonconductive Vacuum Metallization，真空不导电电镀)层201A3、油墨层201A4以及底层油墨层201A5，其中，上述油墨层201A4可以包括至少3层，示例性的，本发明实施例中的油墨层201A4设置为3-4层。示例性的，上述炫光膜片可以通过以下方式获取：对PET膜片进行UV转印压花处理；在PET膜片的一面贴合OCA光学胶；在PET膜片的另一面的涂抹油墨层，在所述油墨层下涂抹底层油墨层，从而获取本发明实施例中需要的炫光膜片，在使用时，只要将撕开贴合在该炫光膜片OCA光学胶上的膜，将该炫光膜片OCA光学胶的一面贴合在玻璃基板的第一面即可。
本发明实施例中的摄像头组件指代包含摄像头壳体，和位于摄像头壳体内部的至少一个摄像头以及与该至少一个摄像头连接的摄像头驱动电路，需要说明的是，本发明实施例中与摄像头组件相对设置的第一通孔均指与该摄像头组件内的摄像头正对设置。
本发明实施例对第一通孔20111的数目不进行限定，该第一通孔20111的数量与电子设备内的摄像头组件中摄像头的数量对应。示例性的，当电子设备内的摄像头组件中包含一个摄像头时，本发明实施例提 供的电池盖在不透光层201A上开设有一个第一通孔20111；当电子设备内的摄像头组件包含两个摄像头时，本发明实施例提供的电池盖201在不透光层上开设有两个第一通孔20111，其中，一个第一通孔20111对应一个摄像头；以此类推，本发明实施例在此不再赘述。
本发明实施例中第一通孔20111的形状和与其相对的摄像头的形状匹配，该第一通孔20111的尺寸应略大于与其相对的摄像头的镜头的尺寸，这样可以增加光线经过第一通孔入射到摄像头的镜头入射角的范围，同时可以避免由于第一通孔尺寸过小遮挡光线。示例性的，该第一通孔的尺寸应该至少保证上述摄像头组件中的摄像头透过，并透过摄像头区域能够正常获取图像。该第一通孔的形状可以为圆形，也可以为椭圆形或者其他形状。
本发明实施例中上述摄像头区域的形状可以为与第一通孔匹配的形状，例如，圆形，椭圆形，也可以为其他形状，本发明实施例对摄像头区域具体形状不进行限定。该摄像头区域的面积大于等于上述第一通孔的面积。
本发明实施例中，上述摄像头区域可以包括一个子区域，也可以包括至少两个子区域，当摄像头区域包括至少两个子区域时，该子区域的数量可以根据第一通孔的数量进行设置。
示例性的，当摄像头区域包括一个子区域时，也即该子区域可以为与摄像头区域形状面积均相同的区域，也可以为位于该摄像头区域内，面积小于摄像头区域面积的区域，且与上述至少一个第一通孔相对设置的区域，可以理解的是，该至少一个第一通孔中每个第一通孔20111在该玻璃基板的摄像头区域的投影位于该子区域范围内，例如，当本发明实施例提供的电池盖在炫光膜片或者油墨层上开设有一个第一通孔20111时，该子区域与该第一通孔20111相对设置，且第一通孔20111在玻璃基板的摄像头区域的投影位于该子区域范围内；当本发明实施例提供的电池盖在不透光层上开设有两个第一通孔20111时，该子区域与该两个第一通孔20111相对设置，且两个第一通孔20111在玻璃基板的摄像头区域的投影位于该子区域范围内。
当本发明实施例提供的电池盖在不透光层201A上开设有两个第一 通孔20111时，相应的，该摄像头区域包括两个子区域，其中，每个子区域对应一个第一通孔；每个第一通孔在摄像头区域上的投影均位于与其相对设置的子区域的范围内；如图3所示，图3为摄像头组件为两个，在炫光膜片或者油墨层上开设有两个第一通孔20111时，上述电池盖的结构示意图，在图3中2011A为一个与摄像头相对设置的子区域，也即摄像头黑圈，2011B为与另一个摄像头相对设置的子区域，也即另一个摄像头的摄像头黑圈，该2011A和2011B共同形成摄像头区域。
为了减少光线反射，增加光线透光率，保证摄像头可视拍摄区域光的透过率，以提高摄像头组件的拍摄效果，在该玻璃基板201B的第一面设置有镀膜层，可以理解的是，该镀膜层可以由多层镀膜组合而成，也可以为单层镀膜，只要该镀膜层的厚度和透光率满足所需要的要求即可，示例性的，该镀膜层的厚度为230nm-250nm，优选的为240nm。
该镀膜层的形状和面积可以与该摄像头区域的形状和面积匹配，即在摄像头区域上覆盖有镀膜层；也可以与摄像头区域的每个子区域的形状和面积匹配，即在每个子区域相对的位置覆盖有镀膜层，这样可以避免在玻璃基板201B的第一面大面积镀镀膜层导致的炫光膜片201A或者油墨层201A与玻璃基板201B第一面附着力降低的问题。
示例性的，本发明实施例中的镀膜层采用减反射(Anti-Reflectance AR)膜(又称：增透膜)。
在光线不佳时，为了对环境光进行补偿，一般电子设备内均设置有闪光灯组件，由于玻璃基板具有导光作用，一方面，本发明实施例可以通过在玻璃基板201B和不透光层201A上均开设与该闪光灯组件相对设置的通孔，以使得闪光灯组件可以透过上述设置在不透光层201A上与闪光灯组件相对的通孔及玻璃基板上与闪光灯组件相对的通孔露在外面来解决串光的问题；另一方面，也可以通过在不透光层201A开设与该闪光灯组件相对设置的通孔，而在玻璃基板201B上不开设通孔(即闪光灯组件不透过上述玻璃基板)，但在玻璃基板201B的表面设置闪光灯区域的方式来解决串光的问题，由于在玻璃基板上开孔或者不开孔对应不同的解决串光的方式，且电池盖的结构也不同，因此，以下结合不同情况详细说明：
需要说明的是，本发明实施例中的闪光灯组件包括至少一个闪光灯以及闪光灯驱动电路，与电子设备的闪光灯组件相对设置的第二通孔2012均指与闪光灯正对设置。该至少一个闪光灯中包括冷色闪光灯和/或暖色闪光灯。
示例性的，一方面，本发明实施例中在不透光层201A上开设有第二通孔2012，该第二通孔2012与电子设备的闪光灯组件相对设置；在玻璃基板201B上开设有与第二通孔2012相对设置的通孔。
本发明实施例中该第二通孔的形状可以与闪光灯组件中闪光灯的形状匹配，且该第二通孔尺寸可以略大于该闪光灯的尺寸，以使得该闪光灯可以透过第二通孔。
本发明实施例设置在玻璃基板201B上的与第二通孔2012相对设置的通孔的形状与第二通孔的形状匹配，该通孔的尺寸与第二通孔的尺寸匹配。
为了保护闪光灯，如图4所示，设置有闪光灯保护罩2063，闪光灯保护罩设置在该第二通孔2012及玻璃基板201B上与第二通孔相对的通孔内，本发明实施例对该闪光灯保护罩2063的具体形状不进行限定，该闪光灯保护罩2063的一端设置有容纳腔，用于容纳闪光灯组件，该闪光灯保护罩2063的另一端用于卡接在第二通孔2012和玻璃基板201B上的与第二通孔相对的通孔内。
由于玻璃基板201B具有导光作用，为了避免闪光灯组件发出的光串光，影响摄像头组件的感光，在闪光灯保护罩2063的另一端与第二通孔2012之间安装有闪光灯装饰件2062，该闪光灯装饰件2062用于包裹闪光灯保护罩2063。在该闪光灯装饰件2062的底部设置有泡棉，用于密封闪光灯装饰件2062，并防止闪光灯组件漏光和进液。示例性的，该闪光灯装饰件2062采用金属装饰件。
另一方面，当玻璃基板201B未开设与第二通孔2012相对的通孔时，即闪光灯组件设置于玻璃基板201B内，不透过玻璃基板201B，仅在不透光层201A上开设有第三通孔，该第三通孔与电子设备的闪光灯组件相对设置；在玻璃基板的第一面设置有闪光灯区域，该闪光灯区域与第三通孔相对设置，在闪光灯区域设置有第二镀膜层，该闪光灯区域的面 积大于等于第三通孔的面积。
在不透光层201A上开设的第三通孔的尺寸和形状均与闪光灯组件中的闪光灯的形状和尺寸匹配。在玻璃基板201B第一面设置的闪光灯区域的形状可以与第三通孔的形状一致，也可以采用与第三通孔不同的形状，该闪光灯区域的尺寸可以略大于第三通孔的尺寸，也可以与第三通孔的尺寸相等；例如，当第三通孔采用圆形时，该闪光灯区域可以采用椭圆形，该椭圆长轴的直径和短轴的直径均应大于等于圆的直径。这样可以降低玻璃基板对闪光灯区域的尺寸加工和镀膜面积要求。闪光灯区域的第二镀膜层采用减反射镀膜层，该减反射镀膜层可以由多层减反射镀膜组合而成，也可以为单层减反射镀膜，只要该第二镀膜层的厚度和透光率满足所需要的要求即可，示例性的，该第二镀膜层的厚度为230nm-250nm，优选的为240nm。
该第二镀膜层的形状和面积可以与该闪光灯区域的形状和面积匹配，即在闪光灯区域上覆盖有第二镀膜层，这样可以避免在玻璃基板201B的第一面大面积镀第二镀膜层导致的炫光膜片201A或者油墨层201A与玻璃基板201B第一面附着力降低的问题。
为了防止闪光灯组件发光时的光线串光至玻璃基板201B的表面，影响摄像头组件的拍摄效果，本发明实施例中将玻璃基板201B表面的闪光灯区域进行处理，例如，玻璃基板201B在闪光灯区域具有相对其他位置较薄的厚度，即，在玻璃基板201B的闪光灯区域设置与闪光灯组件形状尺寸相匹配的凹槽，在凹槽周围设置黑胶，此处的黑胶泛指所有能够遮挡光线的组件，包括但不限于，在凹槽侧壁镀反射膜或在凹槽侧壁贴合不透明材料等方式，只要能够保证闪光灯组件与玻璃基板201B第一面相对的位置透光，而包围闪光灯组件的凹槽侧壁不透光即可，从而能够在闪光灯正常工作的情况下，不影响摄像头组件的拍摄效果。
如图4所示，为了防止灰尘或者液体从第二通孔2012内进入电子设备内部，本发明实施例通过闪光灯罩背胶2061将闪光灯装饰件2062与闪光灯保护罩2063粘结在一起，该闪光灯背胶2061上开设有用于使得该闪光保护罩2063透过的通孔，且该闪光灯背胶2061的尺寸大于闪光灯装饰件2062的尺寸。
为了提高用户外观体验，以及遮挡在不透光层上开设第一通孔由于开孔切边造成的残胶不良和切割锯齿，本发明实施例在玻璃基板201B的第一面或第二面设置有至少一个摄像头黑圈，一个摄像头黑圈与第一通孔相对设置。
可选的，该摄像头黑圈可以通过在该玻璃基板的第一面或第二面与第一通孔相对的区域，通过丝印油墨得到。可以理解的是，该摄像头黑圈的内径小于等于该第一通孔的直径，从而可以遮挡在不透光层201A的残胶不良和切割锯齿问题。
可选的，在玻璃基板201B的第一面或第二面设置有至少一个标识部，该标识部，用于标识安装在电子设备内部的器件的位置或器件采集信号的范围。该标识部可以通过丝印的方式设置在玻璃基板201B的第一面或第二面上与电子设备内部的器件的位置相对的位置。可以理解的是，该标识部可以为丝印在玻璃基板第一面上的标识，用户可以从玻璃基板201B的第二面看到，也可以为丝印在玻璃基板201B的第二面上的标识。
示例性的，本发明实施例中上述标识部可以为丝印在该玻璃基板上的LOGO，或者圆圈。
其中，本发明实施例对上述器件不进行限定，例如，该器件可以为安装在电子设备内部的采集装置和/或者辅助对焦装置。
示例性的，当上述器件为用于采集用户生命体征参数的采集装置时，如图5所示，该玻璃基板201B的第一面或第二面设置第一标识部2014，用于标识上述采集装置采集用户生命体征信号的区域；
在不透光层201A上开设有第三通孔，该第三通孔与第一标识部2014相对设置，用于使得采集装置透过第三通孔与玻璃基板的第一面接触。
具体的，该第一标识部的形状和尺寸可以根据需要进行设置，例如，如图4所示的，丝印在玻璃基板201B第一面或第二面上的圆圈，该第一标识部的尺寸可以根据该采集装置的检测范围进行设置，一般情况下，该第一标识部的尺寸可以小于等于该采集装置最大的检测范围，但是应该大于等于该采集装置最小的检测范围，这样当用户触摸该第一标 识部2014时，采集装置可以采集到用户生命体征信号。
如图5所示，本发明实施例提供一种电子设备20，该电子设备20包括壳体、设置于壳体内的PCB(Printed circuit board，印制电路板)202以及本发明实施例提供的电池盖201，其中，电池盖201与壳体连接，在壳体内设置有与PCB板202连接的摄像头组件203；当电池盖201与壳体连接时，该摄像头组件203与电池盖201上的摄像头区域相对设置，且电池盖201上的不透光层201A靠近PCB板202。
本发明实施例中电子设备的壳体一方面用来组织触摸屏模组，即TP(Touch Panel，触控面板)和LCD(Liquid crystal display，液晶显示器)；另一方面用来固定电子设备的内部器件，例如，PCB板等。
本发明实施例对上述电子设备的壳体和电池盖201的连接方式不进行限定，只要能够保证电子设备的壳体和电池盖201连接即可，示例性的，该电池盖201可以与电子设备的壳体一体式连接，或者该电池盖201可以与电子设备的壳体可拆卸连接，例如，在电子设备的壳体周圈粘胶，或胶水点胶，然后将电池盖201固定在粘胶，或胶水点胶的地方；也可以将该电池盖201通过后壳连接在该电子设备的壳体上。示例性的，如图4或图5所示，在后壳205上设置一圈电池盖背胶207，然后将电池盖201粘在该电池盖背胶207上，并采用一定的压力压合，这样就可以通过电池盖背胶207将该电池盖201组装在后壳205上，该电池盖背胶207的形状和后壳205的形状应该一致，其中，该后壳205上设置有多个螺孔，在电子设备的壳体上设置有与该后壳205上每个螺孔相对设置的螺孔，该后壳205可以通过螺钉与该电子设备的壳体固定连接，同时该后壳205上与电子设备内部器件相对的位置设置有通孔，可以根据需要进行选择设置，例如，在后壳205上设置有摄像头通孔，该摄像头通孔与摄像头组件203相对设置，用于使得电子设备的摄像头组件中的每个摄像头透过该通孔电池盖201接触，例如2015A和2015B；当电子设备内部具有采集装置时，该后壳205上还应该设置有用于使得该采集装置透过的通孔，该用于使得该采集装置透过的通孔与该采集装置相对设备，采集装置透过该通孔能够和第一标识部2014接触；当该电子设备内具有闪光灯组件时，该后壳205上还设置有与该闪关灯组件相对设置 的闪光灯通孔；当该电子设备内具有辅助对焦装置204时，在该后壳205上还设置有与该辅助对焦装置205相对设置的辅助对焦装置通孔，辅助对焦装置通过该辅助对焦装置通孔可以与设置在电池盖201上的第二标识部接触。
可以理解的是，电池盖背胶207上也可以根据需要开设通孔。
如图6所示，该摄像头组件203通过BTB(Board to Board，板对板)连接器2033与PCB板202连接。在该摄像头组件203与电池盖背胶207相对设置的区域设置有摄像头密封泡棉2031，该摄像头密封泡棉2031为大小与摄像头组件203匹配的挡片，在该摄像头密封泡棉2031上开设有通孔(具体的通孔数量根据摄像头组件中摄像头的数量决定)，其中，一个通孔的位置与摄像有组件203中的一个摄像头相对设置，本发明实施例中通过摄像头密封泡棉2031与电池盖背胶207实现摄像头组件203的密封防尘、防进液以及缓冲的作用。
可选的，该电子设备20还包括：闪光灯组件，与PCB板202连接，用于在光线不佳时对环境光进行补偿；
当电池盖201与上述壳体30连接时，闪光灯组件可嵌入设置在第二通孔内的闪光灯保护罩2063的容纳腔内。
可选的，如图7所示，该电子设备20还包括：辅助对焦装置204，设置于PCB板202上，用于测量及识别被拍摄物体的距离，以实现摄像头组件的对焦；当电池盖201与壳体30连接时，辅助对焦装置204与设置在电池盖201上的第二标识部相对设置。
其中，该辅助对焦装置204采用激光传感器。
可选的，为了防止在玻璃基板上开设与激光传感器相对的通孔，影响电池盖的外观，因此，本发明实施例在玻璃基板和炫光膜片或者油墨层上均不开设激光传感器通孔。同时，为了保证激光传感器能够正常工作，本发明实施例在玻璃基板的第一面与该激光传感器相对的位置，丝印有透光油墨(例如，IR透光油墨)，本发明实施例对透光油墨的厚度不进行限定，该透光油墨应该能够保证Crosstalk值小于0.8mk。
该IR透光油墨能够使得激光传感器发出的对应波长的激光透过，并屏蔽不需要的波长(例如，遮挡自然光线中其他的无用光线，防止干 扰，增加激光传感器的灵敏度)；能让比近红外光(Near Infrared，NIR)波长长的红外线透过，并能遮挡低于近红外线波长的可视光和紫外线。在近红外线波长大于850nm左右的范围内，透光率达80％左右对于可视光(400～750nm区域)以及紫外线(190～400nm区域)则能遮挡。
可选的，该电子设备20还包括：采集装置，与PCB板202连接，用于采集用户触摸第一标识部时产生的生命体征信号；
当电池盖201B与壳体连接时，该采集装置与设置在电池盖上的第一标识部相对设置。
具体的，本发明实施例中的采集装置可以为指纹采集装置，该指纹采集装置用于采集用户触摸第一标识部时产生的指纹信号，并将该指纹信号发送至上述PCB板202，然后该电子设备的处理器根据该指纹信号判断该指纹信号是否与用户预先存储的指纹信号匹配，若匹配时，则该处理器解除该电子设备的锁定状态。
需要说明的是，该电子设备内可以具有以下任意一个器件或器件的组合：摄像头组件、闪光灯组件、采集装置、激光传感器。示例性的，该电子设备内可以具有摄像头组件和闪光灯组件；也可以只有摄像头组件；也可以具有摄像头组件和采集装置。
