本申请主张在2019年1月11日在中国提交的中国专利申请No.201910027676.2的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及一种电子设备。
背景技术
电子设备中的一些构件在工作的过程中会产生静电，这些静电为有害因素，会对电子设备产生危害。为了实现静电的泄放，电子设备中在需要接地连通的两个构件之间设置弹性电连接装置，弹性电连接装置通过变形实现装配，最终实现两个构件之间的静电导通，达到将静电导向接地侧的目的。
相关技术中的弹性电连接装置为导电泡棉，通过导电泡棉的弹性变形实现在两个构件之间的弹性装配。我们知道，电子设备总会存在制造误差和装配误差。当两个构件之间的间隙较大时，导电泡棉装配到位之后，会存在导电泡棉由于弹性预压量较小而导致电连接不可靠，进而导致接地存在问题。
为了解决此问题，通常情况下，相比于导电泡棉的尺寸，两个构件之间的间隙偏小，此种情况下，导电泡棉由于弹性预压量较大而保证稳定接触，但是导电泡棉的弹性预压量较大，会导致导电泡棉受压后反弹力较大，最终会使得构件承受较大的弹力而产生损坏。具体地，导电泡棉受压缩方向上接地，受压时导电泡棉在其他方向较难产生弹性扩散，导致导电泡棉施加于与其接触的构件上的反作用力较大，从而引发损坏。
发明内容
本公开提供一种电子设备。
本公开采用下述技术方案：
一种电子设备，包括第一构件和第二构件，所述第一构件和所述第二构 件之间形成间隙，所述间隙内设置有弹性电连接件，所述弹性电连接件包括柔性导电体和流体填充物，所述柔性导电体具有密封内腔，所述流体填充物填充在所述密封内腔中，所述柔性导电体与所述第一构件和所述第二构件弹性电接触。
本公开采用的技术方案能够达到以下有益效果：
本公开公开的电子设备中，弹性电连接件包含设置在柔性导电体的密封内腔中的流体填充物，流体填充物的无定向变形特点，能够使得弹性电连接件设置在第一构件与第二构件之间的间隙中时，弹性电连接件与第一构件和第二构件弹性接触的同时，受第一构件和第二构件的挤压而向多个方向进行变形，相比相关技术中采用导电泡棉而言，本公开公开的电子设备中，弹性电连接件会在受压方向上产生的反弹力较小，能够缓解由于反弹力较大导致的损坏问题。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合本公开具体实施例及相应的附图对本公开技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本公开一部分实施例，而不是全部的实施例。基于本公开中 的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开提供一种电子设备，以解决目前相关技术中的电子设备中通过导电泡棉实现两个构件接地电连接，存在较容易损坏电子设备的问题。
以下结合附图，详细说明本公开各个实施例公开的技术方案。
请参考图1和图2，本公开实施例公开一种电子设备，所公开的电子设备包括第一构件100、第二构件200和弹性电连接件300。
第一构件100和第二构件200分别为电子设备的两个组成构件，而且第一构件100和第二构件200还是在电子设备中需要电连接，进而实现静电传输的构件，第一构件100和第二构件200电连接后，能够最终将两者上的静电导向接地侧，具体地，接地侧可以设置在第一构件100上，也可以设置在第二构件200上，也可以设置在电子设备内与第一构件100或第二构件200电连接的其他构件上。
第一构件100与第二构件200在安装到位后，第一构件100与第二构件200之间可以形成间隙400。弹性电连接件300设置在间隙400中。弹性电连接件300能够实现第一构件100与第二构件200之间的电连接，从而能够实现第一构件100与第二构件200之间的静电传输，最终将第一构件100和第二构件200上的静电泄放到接地侧。
弹性电连接件300可以包括柔性导电体310和流体填充物320。柔性导电体310具有密封内腔，流体填充物320填充在密封内腔中，起到柔性支撑柔性导电体310的作用。柔性导电体310能够导电，柔性导电体310与第一构件100和第二构件200弹性电接触。
本实施例中，柔性导电体310的密封内腔中填充有流体填充物320，流体填充物320具有各向流动的性能，因此能够使得整个弹性电连接件300具备更多方向的变形能力。弹性电连接件300设置在第一构件100与第二构件200之间，从而能够起到弹性导电接触的作用。
通过上述描述可知，本公开实施例公开的电子设备中，弹性电连接件300包含设置在柔性导电体310的密封内腔中的流体填充物320，流体填充物320的无定向变形特点，能够使得弹性电连接件300设置在第一构件100与第二 构件200之间的间隙中时，弹性电连接件300与第一构件100和第二构件200弹性接触的同时，受第一构件100和第二构件200的挤压而向多个方向进行变形，相比相关技术中采用导电泡棉而言，本实施例公开电子设备中，弹性电连接件300会在受压方向产生的反弹力较小，能够缓解由于反弹力较大导致的损坏问题。
由于本实施例公开的弹性电连接件300具备良好的弹性性能以及各方向变形能力，因此在第一构件100和第二构件200之间的间隙400较小时，弹性电连接件300由于良好的多方向变形能力，因此能够在被压后变得较薄，同时又不会对第一构件100和第二构件200产生较大的反作用力，如图3所示。
如上文所述，本实施例不限制第一构件100和第二构件200的具体种类。第一构件100和第二构件200可以是电子设备上任意两个相邻，而且需要电连接来泄放静电的构件。一种具体的实施方式中，第一构件100可以是显示屏组件，第二构件200可以是中框支架，通常，中框支架为金属中框支架。当然，第一构件100也可以是中框支架，第二构件200也可以是电池盖。
上述弹性电连接件300中，流体填充物320可以是液体填充物，例如水、油等。当然，流体填充物320也可以是气体填充物，例如空气、惰性气体等。为了进一步提高变形能力，可选的方案中，柔性导电体310可以是导电薄膜。向密封内腔中填充流体填充物320的技术为公知技术，在弹性电连接件300内填充有气体时，弹性电连接件300可以类似于气球的结构件。再例如，在流体填充物320为液体填充物时，可以先在柔性导电体310上开设填充口，待液体填充物通过填充口填充到密封内腔中之后，再通过胶水或封堵材料将填充口密封。本文中，弹性电连接件300的成型方式有多种，本实施例不限制弹性电连接件300的成型方式。
柔性导电体310能够导电，又为柔性材料制成，使其具备良好的弹性变形能力，此种情况下，流体填充物320才能发挥其能够在多个方向变形的能力。一种具体的实施方式中，柔性导电体310可以包括高分子柔性体和设置在高分子柔性体的外侧表面的导电层，高分子柔性体具有密封内腔。流体填充物320则填充在密封内腔中。具体地，高分子柔性体可以为硅胶体，当然 还可以为其弹性高分子材料制成，本实施例不限制高分子柔性体的具体材质。
导电层可以是镀金层，也可以是导电涂层，还可以是贴附在高分子柔性体的外侧表面上的导电薄膜。本实施例不限制导电层的具体种类。
本实施例中，弹性电连接件300具有良好的变形能力，弹性电连接件300通过预压变形，实现在第一构件100与第二构件200之间的安装。弹性电连接件300的结构可以有多种，例如，弹性电连接件300可以为球形，也可以为椭球形，当然也可以为立方体等。本实施例不限制弹性电连接件300的具体形状。
本公开实施例公开的电子设备可以是平板电脑、手机、游戏机、电子书阅读器、可穿戴设备(例如智能手表)等设备，本公开实施例不限制电子设备的具体种类。
本公开上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本公开的实施例而已，并不用于限制本公开。对于本领域技术人员来说，本公开可以有各种更改和变化。凡在本公开的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本公开的权利要求范围之内。
