电子设备
本申请要求于2021年06月18日提交中国专利局、申请号为202110681173.4、发明名称为“电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电子产品技术领域，尤其涉及一种电子设备。
背景技术
随着手机等电子设备的发展，用户对于手机等电子设备疏水性能的要求越来越高。
为保障电子设备表面的疏水特性，防止因水等液体洒落或喷溅至电子设备后渗入电子设备内部，需要对电子设备进行P2i纳米疏水涂层涂布工序，在进行该工序时需要将整机放入到箱体里，箱体会抽负压以保证涂布效果。
在P2i纳米疏水涂层涂布工序，抽负压时，因电子设备外界的气压发生突变，容易导致电子设备的屏幕发生严重变形而失效。除了该工序，电子设备在其他使用场景(比如高空或者高原或者水下等)中，若其外界气压发生变化，也容易导致屏幕发生变形而失效。
发明内容
本申请实施例提供了一种电子设备，能够解决电子设备因外界气压突变导致屏幕发生变形而造成失效的问题。
一方面，本申请实施例提供了一种电子设备，包括屏幕、中板和盖部，中板位于屏幕和盖部之间，即屏幕和盖部分别设于中板的两侧，中板上开设有通孔，在屏幕和中板之间设有通气流道，屏幕的设定位置与中板之间的部位通过通气流道连通通孔。屏幕可以为柔性屏或者可折叠的屏幕或者刚性屏。屏幕的设定位置不限，可以为容易变形的位置。
在P2i纳米疏水涂层涂布工序或电子设备的其他使用场景，当外界气压发生突变时，屏幕的设定位置和中板之间的空气可以通过通气流道、中板的通孔连通中板和盖部之间的空隙，可解决屏幕因气压差导致变形而造成失效的问题。
基于一方面，本申请实施例还提供了一方面的第一种实施方式：
屏幕包括设定区域，设定位置位于设定区域，即设定区域的范围大于设定位置，设定区域为包含有设定位置的区域，通气流道处于设定区域对应的范围。这样，可以确保设定位置和中板之间的部位与通孔连通的气流路径相对较短，有利于空气的快速导通。
基于一方面的第一种实施方式，本申请实施例还提供了一方面的第二种实施方式：
屏幕在设定区域通过背胶与中板粘接，背胶上形成有至少部分通气流道。这样，设定位置不受包含其的设定区域与中板之间的连接结构的影响，可以确保屏幕在第一区域范围内能够通过通气流道与通孔连通，使设定位置的选取不受限制。
基于一方面，或一方面的第一种或第二种实施方式，本申请实施例还提供了一方面的第三种实施方式：
中板上形成有至少部分通气流道。这样，通气流道的设置更灵活。
基于一方面、一方面的第一种至第三种实施方式中的任一者，本申请实施例还提供了一方面的第四种实施方式：
中板在其通孔位置设有透气膜，透气膜覆盖通孔。这样可以防止中板两侧有灰尘等渗入，保证中板两侧空间的相对密闭性。
基于一方面的第四种实施方式，本申请实施例还提供了一方面的第五种实施方式：
覆盖通孔的透气膜具有防水性能。这样可以提高电子设备的防水性。
基于一方面、一方面的第一种至第五种实施方式中的任一者，本申请实施例还提供了一方面的第六种实施方式：
屏幕的设定位置为开孔位置。该开孔位置可以为前置摄像头对应的开孔位置。在外界气压变化时，屏幕的开孔位置容易变形，将设定位置设定在该开孔位置，可避免因气压差导致的开孔处变形严重的问题。
基于一方面、一方面的第一种至第六种实施方式中的任一者，本申请实施例还提供了一方面的第七种实施方式：
电子设备为防水设备，电子设备具有气流通道，该气流通道的一端连通外界，另一端连通通气流道，即外界通过气流通道、通气流道与通孔连通，外界可与屏幕和中板之间的空隙、中板和盖部之间的空隙连通，气流通道设有防水透气膜。
气流通道内设置的防水透气膜可以确保电子设备的防水性能，外界通过气流通道可以连通中板两侧的空隙，实现了电子设备内部与外界空气的连通，可以避免因电子设备内部与外界存在气压差导致的喇叭出音有杂音等问题；同时，在外界气压突变时，因外界与电子设备内部连通，也能够避免因气压差导致屏幕变形而失效的问题。
基于一方面的第七种实施方式，本申请实施例还提供了一方面的第八种实施方式：
气流通道具有与通气流道连通的内侧端口，即气流通道的内侧端口位于屏幕和中框之间，防水透气膜设于内侧端口。这样，将防水透气膜设置在屏幕和中框之间，可以利用屏幕和中框已有的间隙，避免增加整机厚度。
基于一方面的第八种实施方式，本申请实施例还提供了一方面的第九种实施方式：
在靠近防水透气膜外边缘的位置设有具有防水性的背胶。这样，利用背胶的柔软性，可以给屏幕提供软支撑，避免因防水透气膜的设置造成顶屏而出现屏幕碎亮点或膜印等问题。
基于一方面的第七种至第九种实施方式中的任一者，本申请实施例还提供了一方面的第十种实施方式：
通气流道包括形成于屏幕和中板之间的空隙。这样，利用屏幕和中板之间存在的空隙作为连通屏幕所在侧和盖部所在侧的通气流道的至少部分结构，可以避免增加结构或额外工序。
基于一方面的第七种至第十种实施方式中的任一者，本申请实施例还提供了一方面的第十一种实施方式：
电子设备还包括中框，中框包括前述中板和围设于中板外边缘的边框，气流通道形成于中框。这样，利用已有的中框结构形成连通外界和电子设备内部的气流通道，设置方便，避免增加多余结构，有利于减轻整机重量。

具体实施方式
本申请实施例提供的电子设备，可以为手机或平板电脑，也可以为手持计算机、对讲机、POS机、行车记录仪、可穿戴设备、虚拟现实设备、或车载前装等具有屏幕的终端产品。
请参考图1至图5，为清楚显示结构，图1和图4中均将电子设备的屏幕做透明化处理，即屏幕在图1和图4中为不可视状态。
该实施例中，电子设备包括屏幕10、中框20和盖部30，中框20位于屏幕10和盖部30之间，即屏幕10和盖部30分设于中框20的两侧，可参考图5理解。如图1所示，中框20包括中板21和围设在中板21外边缘的边框22(，其中，中板21和边框可以为分体结构，也可以为一体成型结构。
该实施例中，电子设备包括前置摄像头70，屏幕10具有选定区域11，该选定区域11为覆盖前置摄像头70的具有一定面积的区域，选定区域11的范围大小不限，边界形状也不限，屏幕10在选定区域11具有与前置摄像头70位置对应的开孔111，以便前置摄像头70可以拍照或者摄像等，可以理解，这里的开孔111只是开设在屏幕10的显示区域，屏幕10的盖板上不会开孔，参考图3，为清楚示意该开孔111位置，图3中屏幕10为透视图，开孔111以虚线示意。
前置摄像头70的主体位于中板21和盖部30之间，中板21具有摄像头孔212，该摄像头孔212的位置与开孔111位置对应，且摄像头孔212和开孔111连通，即摄像头孔212与前置摄像头70的位置对应，以便于前置摄像头70的镜头部分可以位于摄像头孔212和开孔111中。
参考图3和图5理解，在前置摄像头70和中板21之间设有密封件71，以确保前置摄像头70所在区域的密封性，防止灰尘等落入。该密封件71可以为环状密封圈或者泡棉或者密封胶等任何可以实现密封的部件，该密封件71可以绕前置摄像头70一周，以实现密封。
中板21具有通孔一211，该通孔一211位于摄像头孔212的旁侧，与摄像头孔212之间具有一定的距离，该距离也不限，实际设置时可以根据需要确定。
在屏幕10和中板21之间设有通气流道51，屏幕10的开孔111所在位置与中板21之间的部位通过该通气流道51与通孔一211连通，即开孔111位置处的空气可以通过通气流道51、通孔一211与中板21和盖部30之间的空气导通。
该实施例提供的上述电子设备，在P2i纳米疏水涂层涂布工序中，当外界气压发生突变时，屏幕10的开孔111位置处的空气经通气流道51与通孔一211与中板21和盖部30之间的空隙导通，可解决屏幕10因受内外气压差发生变形导致的失效，特别是可以缓解屏幕10在开孔111位置处的变形。除了上述P2i纳米疏水涂层涂布工序，电子设备在存在外界气压突变的使用场景中，同样能够避免屏幕10因气压差导致的变形失效问题。
该实施例提供的电子设备的屏幕10可以为柔性屏，也可以为折叠屏，还可以为刚性屏，在此不限制屏幕10的类型。
屏幕10在选定区域11处通过背胶40与中板21粘接密封，以防止灰尘等杂质进入选定区域11，确保前置摄像头70的拍照或摄像效果。
该实施例中，背胶40呈片状结构，其基本覆盖选定区域11所在范围，中板21的通孔一211位于选定区域11所在范围，即通孔一211处于背胶40覆盖的范围。参考图2至图5，位于屏幕10和中板21之间的通气流道51全部形成于背胶40，结合图2和图3理解，通气流道51实际为设置在背胶40上的通孔结构，具体的，该通气流道51包括第一流道段511、第二流道段512和第三流道段513，其中，第一流道段511为背胶40在对应于开孔111位置设置的第一圆形通孔，该第一圆形通孔511大于开孔111设置，开孔111位于第一圆形通孔的范围内，第三流道段513为背胶40在对应于通孔一211位置设置的第二圆形通孔，第二圆形通孔大于通孔一211设置，通孔一211位于第二圆形通孔的范围内，第二流道段512为连通第一圆形通孔和第二圆形通孔的直线形通孔。
上述通气流道51的设置，通气流道51处于选定区域11，开孔111位于第一圆形通孔即第一流道段511的范围内，可以确保开孔111周边的空气都能够与中板21和盖部30之间的空气导通，通孔一211位于第二圆形通孔范围即第三流道段513内，并且开孔111位置与通孔一211之间的气流路径相对较短，有利于空气的快速导通，因为屏幕10在开孔111处容易形成应力集中，所以当外界气压突变时开孔111的边缘容易 失效，空气快速导通后可以有效规避屏幕10因外界气压突变造成变形而导致失效。
在其他实施例中，第一流道段511和第三流道段513也可以为其他形状的通孔，不限于图示中的圆形，比如可以为矩形、方形或者椭圆形等规则形状，当然，也可以为不规则形状，连通第一流道段511和第三流道段513的第二流道段512也可以为其他形状，不限于直线形，比如可以为折线形，或者弧形，或者其他曲线形等。
该实施例中，设置在开孔111位置和通孔一211之间的通气流道51为一个，在其他实施例中，也可以设置多个，比如可以设置两个以上的连通第一流道段511和第三流道段513的第二流道段512，这些第二流道段512的形状可以不同，也可以相同。
该实施例中，在中板21的通孔一211处还设有透气膜61，该透气膜61覆盖通孔一211，可以理解，透气膜61为允许空气通过的膜材料制成，这样，开孔111位置的空气经通气流道51流到通孔一211位置后，可经透气膜61流入中板21和盖部30之间；透气膜61的设置可以隔绝中板21两侧的灰尘、脏污、异物等，也可以避免通道堵塞。其中，透气膜61可以通过胶粘等方式与中板21相对固定，比如透气膜61可通过粘接件80与中板21相对固定。
该透气膜61具体可以选用具有防水性能的透气膜，以提高电子设备的防水性能。具体的，透气膜61可以为一层结构，也可以为两层以上的结构，其材质可以为半透膜与基材结合的膜片状高分子材料，包括PP(polypropylene，聚丙烯)无纺布，PE(polyethylene，聚乙烯)高分子透气膜等。
该实施例中，在屏幕10的对应前置摄像头70位置的开孔111处与通孔一211之间形成通气流道51，在其他实施例中，若屏幕10在其他位置设有孔结构或者根据实验或仿真等方式事先获知屏幕10存在其他受气压差容易变形的位置或者存在对屏幕变形比较敏感的位置，可以在相应位置设置通气流道，这些位置称之为设定位置，相应地，在屏幕10上可以框定出包含该设定位置在内的设定区域，该设定区域的形状和大小可以根据需要设定，在设定区域内设置通气流道，以将屏幕10的设定位置与中板21之间的部位与形成在中板21上的通孔连通。可以理解，屏幕10的前述设定位置可以为一处，也可以为两处以上，当设定位置为两处以上时，可以只在中板21上设置一个通孔，这些设定位置对应的通气流道均与该通孔连通，当然，也可以在中板21上设置两个以上的通孔。
在其他实施例中，通气流道51也可以完全不处于设定区域，或者不完全处于设定区域，此时，通气流道51的至少部分不在背胶40对应范围内，若这个范围内屏幕10和中板21之间无其他结构，那么通气流道51可以包括形成在屏幕10和中板21之间的空隙，即利用已有的屏幕10和中板21之间的空隙作为通气流道51的至少一部分，可以简化结构。在其他实施例中，中板21的通孔一211也可以不处于背胶40所在区域，此时，通气流道51的部分可以形成于背胶40上，其余部分可以为屏幕10和中板21之间的空隙部分，当然这两部分需要连通。
在上述实施例中，在选定区域11，屏幕10和中板21之间的背胶40为覆盖该选定区域11的片状结构，在其他实施例中，背胶40也可以为与选定区域11外边缘对应的封闭圈结构，此时，通气流道51可以完全利用屏幕10和中板21之间的既有空隙，当 然，若在通气流道51的气流路径上，存在有背胶40的一部分，那么可以在该干涉部分形成不同形状的通孔以组成通气流道51的一部分。
请参考图6至图10，为清楚显示结构，图6和图9中均将电子设备的屏幕做透明化处理，即屏幕在图6和图9中为不可视状态。
该实施例中的电子设备的基本结构组成与前述图1至图5所示的实施例类似，两者的区别在于：通气流道51的形成方式不同，下面仅就该区别做详细说明，其余部分均可参考上述图1至图5所示的实施例的描述，不再重复。
该实施例中，仍选定屏幕10上对应前置摄像头70的开孔111为设定位置，相应地，包括该开孔111的选定区域11为设定区域。
该实施例中，位于屏幕10和中板21之间的通气流道51也包括第一流道段511、第二流道段512和第三流道段513，可参考图7和图8理解，其中，第一流道段511和第三流道段513的结构与前述图1至图5所示的实施例一致，分别为背胶40在对应于开孔111位置设置的第一圆形通孔和在对应于通孔一211位置处设置的第二圆形通孔，第二流道段512连通第一流道段511和第三流道段513，区别于前述图1至图5所示的实施例，第二流道段512形成于中板21，具体为形成在中板21上的槽结构，如图8所示，该槽结构贯通中板21的通孔一211和开孔212。将第二流道段512形成在中板21上，方便加工，便于根据需要控制第二流道段512的流通面积。
因槽结构的第二流道段512连通通孔一211和开孔212，所以，实际设置时，也可以不在背胶40上形成第一流道段511和第三流道段513，第二流道段512与通孔一211和开孔212贯通处的流通面积可以适当增大，以使空气在整个流动路径上的流动较为平稳。
中板21上形成的第二流道段512的形状不限，可以为直线形或者曲线形或者蛇形或者阶梯形等不同形式。
结合上述图1至图5所示的实施例和图6至图10所示的实施例，电子设备还可以有其他变形实施例，比如说，电子设备的通气流道51还可以利用屏幕10和中板21之间的既有空隙，实际设置时，屏幕10通过其他背胶等胶粘件与中板21相对固定，所以屏幕10和中板21之间存在有空隙。
请参考图11至图13，图11为电子设备的透视图，其内部结构以虚线示意，图12中为了清楚示意气流通道的连通位置，以虚线示意其内部结构。
该实施例提供的电子设备为防水设备，比如可以为具备防水功能的手机，如图11和图12所示，该电子设备包括屏幕10、中框20和盖部30，中框20包括中板21和围设在中板21外边缘的边框22，该边框22位于中板21和盖部30之间，中板21和边框22可以为分体结构，也可以为一体结构。屏幕10和盖部30分设于中框20的两侧。
与前述图1至图5所示的实施例和图6至图10所示的实施例相比，该实施例的电子设备具有防水功能，屏幕10和中板21周圈用防水胶水或者背胶(图中未画出)贴合来实现防水。电子设备具有连通外界的气流通道52，气流通道52可以是任意形状，也可以利用已有的孔结构，该气流通道52与屏幕10的设定位置和中板21之间的部位连通，在该实施例中，屏幕10的设定位置为与气流通道52位于电子设备内部的内侧 端口对应的位置，中板21具有通孔二211＇，屏幕10的设定位置和中板21之间的部位通过通气流道51与通孔二211＇连通，即，外界可通过气流通道52连通屏幕的设定位置和中板21之间的部位，并通过通气流道51、通孔二211＇连通中板21和盖部30之间的空隙，在该实施例中，通气流道51为形成于屏幕10和中板21之间的空隙，其形状不规则，可结合图11和图13理解，图11中以以虚线实心箭头示意了外界空气流入电子设备的大致流动路径，其中，位于电子设备内部的虚线实心箭头示意区域可以理解为通气流道51的一部分。也就是说，外界与手机内部连通，同时，在气流通道52处设有防水透气膜62，以确保电子设备的防水性能，图示示例中，防水透气膜62呈长方形形状，可以理解，实际设置时，防水透气膜62的形状不限。
该电子设备的连通外界的气流通道52连通的是屏幕10所在侧位置，空气的流通方向为屏幕10与中板21之间向中板21与盖部30之间，消除了因屏幕10与中板21之间空隙较小导致的空气流通不畅的问题，可实现外界大气与电子设备内部屏幕10所在侧空气的快速导通，在P2i纳米疏水涂层涂布工序或其他外界气压发生突变的使用场景中，可保证屏幕10不会因气压差导致的失效问题；因电气设备内部与外界可导通，在电子设备具有喇叭等结构时，还可规避喇叭出音有杂音的问题。
该实施例中，防水透气膜62的结构与前述图1至图5所示的实施例介绍的具有防水功能的透气膜61的结构类似，不再重复说明。
该实施例中，气流通道52形成于中框20，设置方便，可避免增加多余结构，也不影响电子设备的厚度。如图11至图13所示，气流通道52的一部分形成于边框22，另一部分形成于中板21。图示示例中，气流通道52为直线形形状的通孔，在其他实施例中，气流通道52也可以为折线形或者曲线形等形式，气流通道52也可以完全形成在中板21上。具体的，气流通道52可以设置于中框20上已有的USB孔或者音频出音孔或者其他接头孔等，以简化结构。
气流通道52具有与通气流道51连通的内侧端口，即气流通道52的内侧端口朝向屏幕10，该实施例中，将防水透气膜62设置在气流通道52的内侧端口处，即防水透气膜62位于屏幕10和中板21之间，这样，不但组装方便，也利用了屏幕10和中框20之间的实际存在的空隙，可以避免增加电子设备的厚度，另外，也方便根据需要设置内侧端口的大小及防水透气膜62的大小，避免因防水透气膜62的大小设计要求而增加其他部件的体积，有利于降低整机的重量。
该实施例中，还可以在靠近防水透气膜62外边缘的位置设置防水背胶63，防水背胶63的位置可以设在根据设计经验或者仿真识别的可靠性高风险位置。图示示例中，防水背胶63为一个长条状结构，位于防水透气膜62和通孔二211＇之间，相对靠近防水透气膜62设置。
防水背胶63的设置，可以实现外部进液的双重拦截，提高电子设备的防水性能；实际设置时，防水背胶63的厚度小于或等于屏幕10和中板21之间的间隙，防水透气膜62的厚度小于或等于屏幕10和中板21之间的间隙，可以让防水背胶63的厚度稍大于防水透气膜62的厚度，所以防水背胶63可以提供支撑，这样还可以利用防水背胶63的柔软性，给屏幕10提供软支撑，避免因防水透气膜62对屏幕10造成顶屏而 出现屏幕碎亮点或膜印等问题。
该实施例中，通气流道51全部为形成于屏幕10和中板21之间的空隙，即外界空气经气流通道52进入电子设备内部后，经过防水透气膜62的拦截，只有空气通过，灰尘和水等不会进入电子设备内部，进入的空气沿屏幕10和中板21之间的空隙流向中板21的通孔二211＇，之后流入中板21和盖部30之间的间隙，实现外界与电子设备内部的空气导通。参考图11，可以理解，因防水背胶63的设置，通过防水透气膜62的空气绕过防水背胶63后，沿屏幕10和中板21之间的空隙流向通孔二211＇，图11中以虚线实心箭头示意了外界空气流入电子设备的大致流动路径。
该实施例中，屏幕10的设定位置为靠近屏幕10边缘的位置，可以为屏幕10的上边缘或者下边缘，还可以是侧边缘。在该实施例中，可以将气流通道52的内侧端口对应的屏幕10位置理解为设定位置。当然，在其他实施例中，只要气流通道52允许，屏幕10的设定位置可以为其他任何位置。
为避免影响空气的流通，实际设置时，防水背胶63在防水透气膜62的外边缘处不形成封闭的环形结构，防水背胶63可以为块状结构或其他形状的结构，可以设置一个或多个，当设置多个时，多个防水背胶63在靠近防水透气膜62的外边缘处间隔设置，相邻的防水背胶63之间的空间形成通气流道51的一部分。当然，防水背胶63也可以呈封闭的环状结构，此时，该防水背胶63可以理解为屏幕10上包含上述设定位置的设定区域中设置的背胶，通气流道51的一部分可以形成于该防水背胶63。
参考前述图1至图5所示的实施例和图6至图10所示的实施例，该图11至图13所示实施例的变形例中，通气流道51可以有部分形成于中板21上。该实施例还可以有其他变形例，比如与前述图1至图5所示的实施例或图6至图10所示的实施例结合，气流通道52与屏幕10的开孔111处连通，或者，在前述图1至图5所示的实施例或图6至图10所示的实施例的基础上，设置另一个区别于开孔111处的其他设定位置，即将图11至图13所示实施例的结构与前述图1至图5所示实施例或图6至图10所示实施例简单组合在一起，中板21的通孔一211和通孔二211＇可以为两个位置的不同通孔，也可以为同一通孔。
本文中应用了具体个例对本发明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发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
