本申请要求在2019年6月24日提交中国国家知识产权局、申请号为201910550492.4的中国专利申请的优先权，发明名称为“一种可折叠电子设备”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
本申请涉及电子设备技术领域，尤其涉及一种可折叠电子设备。
背景技术
随着人们对电子设备的要求越来越高，可折叠电子设备逐渐被广泛应用；以手机为例，可折叠手机一般包括通过铰链进行连接的两个主体，当手机折叠后能够降低体积的占用，从而具有较好的便携性；另外，当可折叠手机在展开后，可以为用户提供更大的显示面积，从而能够提升用户的视觉体验和操作便利性，进而能够满足用户的多方面需求。
在实际应用中，可折叠手机的两个主体之间往往需要实现电器连接；传统的实施方式中，一般通过柔性电路板(flexible printed circuit，FPC)实现两个主体之间的电器连接，当可折叠手机在进行折叠时柔性电路板会随之产生弯曲；但是在实际情况中，柔性电路板的弯曲形态及产生弯曲的位置并不可控；因此，可能会造成柔性电路板局部过度弯折的情况，容易发生断线等不良情况。
发明内容
本申请提供了一种可有效控制柔性电路板弯曲形态的可折叠电子设备。
本申请提供的可折叠电子设备，包括：第一主体、第二主体、柔性电路板以及磁吸固定件；所述第一主体和所述第二主体通过铰链连接，以实现第一主体和第二主体之间的相对转动、折叠；柔性电路板的第一端与所述第一主体电连接，第二端与所述第二主体电连接；以跨过铰链实现第一主体和第二主体之间的电连接；磁吸固定件与所述铰链吸附固定，用于实现柔性电路板与铰链之间的固定连接；其中，所述柔性电路板的第一端与所述第二端之间具有固定部，所述固定部夹持固定在所述磁吸固定件与所述铰链之间。本申请提供的可折叠电子设备中，由于柔性电路板的固定部与铰链固定连接，使得可折叠电子设备在折叠、展开过程中柔性电路板不会朝第一主体或第二主体偏移，从而能够防止柔性电路板在第一主体处或第二主体处产生堆积，导致柔性电路板局部过度弯曲的情况。另外，还能够防止柔性电路板与铰链之间产生摩擦，有效地避免了柔性电路板受铰链摩擦损坏情况的发生。另一方面，位于第一端和固定部之间的柔性电路板以及位于第二端和固定部之间的电路板可以独立的随着可折叠设备的折叠、展开而产生弯曲形变，避免相互干扰，从而使得柔性电路板的弯曲形态更加可控。
在一些具体实施方式中，所述柔性电路板还可以包括第一连接部和第二连接部；其中，所述第一连接部位于所述第一端和所述固定部之间，所述第二连接部位于所述第二端和所述固定部之间；所述第一连接部与所述第一主体固定连接，所述第二连接部与所述第二主体固定连接。
在实际应用中，柔性电路板的固定部与第一端和第二端之间的长度可能会较长；通过将第一连接部与第一主体进行连接、将第二连接部与第二主体进行连接的方式可提升柔性电路 板弯曲形变时的可控性。
其中，第一连接部和第二连接部与固定部之间的长度可以是多样的；例如，在本申请提供的一个具体实施方式中，所述第一连接部和所述第二连接部关于所述固定部对称设置，即第一连接部与固定部之间的距离与第二连接部与固定部之间的距离相同；当然，在一些具体实施方式中，第一连接部与固定部之间的距离也可以大于或小于第二连接部与固定部之间的距离。
另外，在一些具体实施方式中，为了提升磁吸固定件与柔性电路板之间的摩擦力，所述磁吸固定件具有用于与所述固定部相抵的吸附面；所述吸附面上可以设置至少一个凸点。当磁吸固定件的吸附面与柔性电路板相贴合时，凸点能够增加与柔性电路板之间的压强以及摩擦力，从而提升柔性电路板与磁吸固定件、铰链之间的相对稳定性。
在另一些具体实施方式中，所述磁吸固定件具有用于与所述固定部相抵的吸附面；所述吸附面上还可以设置至少一个定位柱；所述固定部具有供所述至少一个定位柱穿设的通孔；相应的，所述铰链具有用于与所述至少一个定位柱插接的定位孔。
当磁吸固定件与铰链吸合时，定位柱能够穿过通孔并与定位孔插接，从而能够有效提升柔性电路板与磁吸固定件、铰链之间的相对稳定性。
其中，柔性电路板可以与多种不同结构类型的铰链实现固定连接。例如，在本申请提供的一种具体实施方式中，所述铰链包括中心轴、第一转动体和第二转动体；其中，所述第一转动体和所述第二转动体通过所述中心轴转动连接；所述第一转动体与所述第一主体固定连接，所述第二转动体与所述第二主体固定连接，所述磁吸固定件与所述中心轴吸附固定。
另外，为了提升柔性电路板本身的形变可控性，在本申请提供的一种具体实施方式中，所述柔性电路板具有形变区和保持区；其中，所述形变区的抗形变性低于所述保持区的抗形变性。
在具体实施时，所述形变区和所述保持区可以具有多个；可选的，可以在所述柔性电路板的第一端至第二端的方向上，交替设置所述形变区和所述保持区。
另外可折叠电子设备具体可以为笔记本电脑、可折叠手机、电子书等；当然，为了为用户提供显示功能，所述第一主体和/或所述第二主体上可以设置显示屏。在具体实施时，显示屏分为独立的两块，并分别设置在第一主体和第二主体上；当然，显示屏也可以为独立的一整块，其中一部分设置在第一主体上，另一部分设置在第二主体上。另外，在一些具体实施方式中，也可以是仅在第一主体或第二主体上设置显示屏。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种表达形式，除非其上下文中明确地有相反指示。还应当理解，在本申请以下各实施例中，“至少一个”、“一个或多个”是指一个、两个或两个以上。术语“和/或”，用于描述关联对象的关联关系，表示可以存在三种关系；例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A、B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
为了方便理解本申请实施例提供的可折叠电子设备，下面首先介绍一下其应用场景。如图1所示，可折叠电子设备具体来说是可以通过折叠、旋转等方式改变其自身形态的电子设备；在不同使用需求条件下，用户可以对可折叠电子设备进行折叠、旋转来满足用户的不同需求。例如，当用户需要随身携带可折叠电子设备时，可以通过双手把持可折叠设备的左右两个部分对其进行折叠，以降低其体积，从而提升便携性；当用户在使用可折叠电子设备时，可以通过双手把持可折叠设备的左右两个部分将其展开，以提供更大的显示区域或操作区域，从而提升使用便利性。在实际应用中，可折叠电子设备的类型可以分为多种，例如其具体可以为笔记本电脑、可折叠手机、电子书等。
以可折叠手机为例，通常包括通过铰链进行连接的两个主体，在铰链的作用下，两个主 体之间能够产生相对转动、滑动等动作。由于两个主体之间需要进行电连接，以实现电能或者电信号的传输，因此，两个主体之间可以通过柔性电路板(flexible printed circuit，FPC)进行连接；由于柔性电路板与铰链之间的旋转半径不同，使得在不同折叠状态下，所需的柔性电路板的长度是不同的。具体来说，在一种具体实施方式中，如图2所示，当可折叠手机处于展开状态时，柔性电路板4处于平直状态；如图3所示，当可折叠手机趋于折叠时，由于柔性电路板4的旋转半径小于铰链3的旋转半径，使得柔性电路板4产生多余长度，并驱使柔性电路板4局部随机弯曲形变或偏移；具体的，请继续参阅图3，柔性电路板4整体朝靠近第一主体1的方向偏移，同时，弯曲形变的部位也集中在靠近第一主体1的部分，这就容易造成柔性电路板4局部过度弯曲，或者与铰链3等部件产生摩擦，致使柔性电路板4产生折损、磨损甚至于断线失效等不良情况。
另外，如图4所示，在另一种具体实施方式中，当可折叠手机处于折叠状态时，柔性电路板4处于平滑弯曲的状态；如图5所示，当可折叠手机趋于展开时，由于柔性电路板4的旋转半径大于铰链3的旋转半径，使得柔性电路板4产生多余长度，并驱使柔性电路板4局部随机弯曲形变或偏移，具体的，请继续参阅图5，柔性电路板4整体朝靠近第一主体1的方向偏移，同时，弯曲形变的部位也集中在靠近第一主体1的部分；这就容易造成柔性电路板4局部过度弯曲，或者与铰链3等部件产生摩擦，致使柔性电路板4产生折损、磨损甚至于断线失效等不良情况。
如上述情况所述，为了避免柔性电路板出现上述的不良情况，在本申请实施例提供的一种可折叠电子设备中，柔性电路板与第一主体和第二主体固定连接的同时还与铰链固定连接。
具体来说，如图6所示，柔性电路板4具有第一端41和第二端42，其中，第一端41与第一主体1连接，第二端42与第二主体2连接；在第一端41和第二端42之间具有固定部43，该固定部43与铰链3固定连接。由于固定部43与铰链3固定连接，使得可折叠电子设备在折叠、展开过程中柔性电路板4不会朝第一主体1或第二主体2偏移，从而能够防止柔性电路板4在第一主体1处或第二主体2处产生堆积，导致柔性电路板4局部过度弯曲的情况。另外，还能够防止柔性电路板4与铰链3之间产生摩擦，有效避免柔性电路板4受铰链3摩擦损坏情况的发生。另一方面，位于第一端41和固定部43之间的柔性电路板以及位于第二端42和固定部43之间的柔性电路板可以独立的随着可折叠设备进行折叠、展开而产生弯曲形变，避免相互干扰，从而使得柔性电路板4的弯曲形态更加可控。
在具体实施时，柔性电路板4的第一端41可以通过连接器1a与第一主体1进行连接，柔性电路板4的第二端42可以通过连接器1b与第二主体2进行连接；另外，在一些具体实施方式中，柔性电路板4还可以通过焊接等方式实现与第一主体1和第二主体2之间的连接。
其中，为了实现柔性电路板4与铰链3之间的固定连接，如图7所示，在本申请提供的一个实施例中，柔性电路板4可通过磁吸固定件5与铰链3固定连接。即，柔性电路板4的固定部43夹持固定在磁吸固定件5与铰链3之间，通过柔性电路板4与磁吸固定件5和铰链3之间的摩擦力实现三者之间的相对固定。
在一些具体实施方式中，磁吸固定件5具体可以为磁铁，铰链3可以由铁磁性材料制成，或者铰链3中的某个相关组成部件，或某个相关组成部件中的一部分由铁磁性材料制成，以能够与磁吸固定件5相互吸合。通过磁吸固定件5与铰链3相吸合的方式，可极大降低可折叠电子设备的装配难度，并能提升装配工序时的可操作性；具体来说，在一些具体实施方式中，可能无法在铰链3中开设用于与柔性电路板4相连接的结构(例如螺纹孔)，通过磁吸固定件5可简单、快捷、可靠地实现柔性电路板4与铰链之间的连接。其中，铁磁性材料可以 包括铁、镍、钴等。当然，磁吸固定件5与铰链3的具体结构形态可以是多样的。
例如，如图8所示，在本申请提供的一个实施例中，磁吸固定件5为块状结构，并具有用于与柔性电路板4的固定部43贴合(与铰链吸合)的吸附面51。在具体实施时，该吸附面51可以为如图7所示的平面结构，也可以为如图9所示的曲面结构。
例如，如图10所示，在本申请提供的一个具体实施方式中，该吸附面(图中未示出)为平面；相应的，为了保证磁吸固定件5与铰链3之间的吸合稳定性，铰链3具有平整的固定面31，该固定面31用于与柔性电路板4的固定部43贴合(与磁吸固定件5的吸附面吸合)。
如图11所示，在本申请提供的另一个具体实施方式中，该吸附面51上还可以具有凸点结构52；通过这种结构设置可以提升吸附面51与柔性电路板4的固定部43之间的压强，以及铰链3与柔性电路板4之间的压强，从而提升柔性电路板4与磁吸固定件5和铰链3之间的摩擦力，提升三者之间的相对稳定性。
其中，如图12所示，在一些具体实施方式中，也可以在固定面31上设置凸点结构32。当然，在其它实施例中还可以在吸附面51和固定面31上均设置凸点结构，以增加柔性电路板4与磁吸固定件5和铰链3之间的摩擦力。
当然，在一些具体实施方式中，如图13所示，磁吸固定件5还可以沿柔性电路板3的宽度方向间隔设置多个(图中以示出有两个为例)，以提升柔性电路板4与铰链3之间的摩擦力；另外，磁吸固定件5还可以为如图14所示的长条状结构，以增加与柔性电路板4之间的接触面积，从而提升柔性电路板4、磁吸固定件5、铰链3之间的相对稳定性。
另外，如图15和图16所示，在本申请提供的另一个具体实施方式中，吸附面51上还可以设置定位柱53，柔性电路板4的安装面上具有定位孔33，柔性电路板4的固定部43具有供定位柱53穿设的通孔44。当磁吸固定件5与铰链3吸合时，定位柱53穿过该通孔44后与定位孔33插接。通过这种方式，可有效提升磁吸固定件5、柔性电路板4和铰链3之间的连接稳定性，防止相对滑动。
在具体实施时，定位柱53、通孔44以及定位孔33的数量以及位置排布可以是多样的；另外，在一些具体实施方式中，定位柱53也可以是设置在铰链3上，相应的，定位孔33可以设置在磁吸固定件5上。当然，定位柱53也可以是设置在柔性电路板4的上、下两侧，并在磁吸固定件5和铰链3上分别设置与定位柱53插接的定位孔33，以提升磁吸固定件5、柔性电路板4和铰链3之间的连接稳定性。
在具体应用时，柔性电路板4的固定部43可能距离柔性电路板4的第一端41和第二端42之间的长度较长，为了提升柔性电路板4弯曲形变时的可控性，可以通过将柔性电路板4与第一主体1和第二主体2分别进行连接的方式，以提升柔性电路板4弯曲形变时的可控性。
例如，如图17所示，在本申请提供的一个实施例中，柔性电路板4还包括第一连接部45和第二连接部46；其中，第一连接部45位于第一端41和固定部43之间，第二连接部46位于第二端42和固定部43之间。具体的，第一连接部45与第一主体1固定连接，第二连接部46与第二主体2固定连接。通过这种方式可将柔性电路板4的形变区有效的控制在固定部43和第一连接部45之间、以及固定部43和第二连接部46之间。
进一步地，如图18所示，具体来说，由于第一端41和第一连接部45均与第一主体1固定连接，因此，可折叠电子设备在进行折叠以及展开时，第一端41和第一连接部45之间的长度并不会发生变化；相应的，第二端42和第二连接部46之间的长度也不会发生变化。如图19所示，随着可折叠电子设备的折叠以及展开，固定部43与第一连接部45之间会产生长度变化，使得该段的柔性电路板产生弯曲形变；相应的，固定部43与第二连接部46之间也 会产生长度变化，使得该段的柔性电路板产生弯曲形变。但是这些弯曲形变的程度相较于现有技术柔性电路板4弯曲形变的程度而言，可以减轻较多，从而可以防止柔性电路板4局部过度弯折，导致容易发生断线等不良情况。
在具体实施时，固定部43与第一连接部45之间的距离L1，以及固定部43与第二连接部46之间的距离L2的相对关系可以是多样的。例如：L1>L2，L1<L2或L1＝L2；即，第一连接部45和第二连接部46可以关于固定部43非对称设置，也可以关于固定部43对称设置。
另外，第一连接部45与第一主体1之间的连接方式、第二连接部46与第二主体2之间的连接方式可以与固定部43与铰链3之间的连接方式相同；具体来说，第一连接部45可以通过磁吸固定件5与第一主体1进行连接，第二连接部46可以通过磁吸固定件5与第二主体进行连接。
在一些具体实施方式中，第一连接部45还可以采用粘接、焊接、螺钉连接等方式实现与第一主体1之间的连接；相应的，第二连接部46也可以采用粘接、焊接、螺钉连接等方式实现与第二主体2之间的连接。
另一方面，在其他实施方式中也可以在柔性电路板4中设置形变区和保持区来提升柔性电路板4弯曲形变时的可控性。具体来说，如图20所示，形变区4a的抗形变性能小于保持区4b的抗形变性能；当柔性电路板4弯曲时，由于形变区4a的抗形变性能小于保持区4b的抗形变性能，因此，形变区4a会产生弯曲形变，而保持区4b会相对保持平直状态。在具体实施时，形变区4a的厚度可以是小于保持区4b的厚度；例如，可以对柔性电路板的部分区域进行加厚处理以形成保持区4b；另外，形变区4a和保持区4b的数量和位置排布可以是多样的。
例如，请继续参阅图20，在本申请提供的一个实施例中，在柔性电路板4的第一端41至第二端42的方向上交替设置形变区4a和保持区4b；具体来说，形变区4a具有两个，保持区4b具有三个。其中，固定部43、第一连接部45和第二连接部46可以分别位于3个保持区4b内，固定部43与第一连接部45之间以及固定部43和第二连接部46之间的部分可以分别设置一个形变区4a。
在本申请提供的实施例中，通过将柔性电路板4的固定部43与铰链3进行连接，以当可折叠电子设备的第一主体1和第二主体2通过铰链3进行折叠以及翻转时，位于固定部43两侧的部分可独立的进行弯曲形变，以避免两个部分相互干扰，从而能够提升柔性电路板4在弯曲形变时的可控性。另外，通过第一连接部45和第二连接部46使得柔性电路板4分别与第一主体1和第二主体2固定连接，可有效控制柔性电路板4的弯曲形变区域，也能够提升柔性电路板4在弯曲形变时的可控性。另一方面，通过在柔性电路板4中设置形变区4a和保持区4b，也能够有效地提升柔性电路板4在弯曲形变时的可控性。
当然，上述的柔性电路板4对于多种不同类型的铰链3的结构均能适用。例如，如图21所示，在本申请提供的一个实施例中，铰链3包括中心轴34、第一转动体35和第二转动体36；其中，第一转动体35和第二转动体36通过中心轴34转动连接；即第一转动体35和第二转动体36能够以中心轴34为旋转轴心进行相对转动。第一转动体35与第一主体连接，第二转动体36与第二主体连接，以实现第一主体与第二主体之间的相对转动以及折叠。
在具体实施时，柔性电路板4的固定部43可以与中心轴34固定连接；具体来说，中心轴34可以为铁磁性材质，磁吸固定件5能够与中心轴34进行吸合，并将柔性电路板4的固定部43夹持固定在中心轴34和磁吸固定件5之间。当然，中心轴34的外周也可以对应设置平面结构341以提升与磁吸固定件5(或柔性电路板4)之间的贴合面积，以增加磁吸固定件 5、柔性电路板4以及中心轴34之间的相对稳定性。
另外，如图22所示，在本申请提供的另一个实施例中，铰链3还可以包括第一转动体37、第二转动体38和第三转动体39；具体的，第一转动体37、第二转动体38和第三转动体39依次铰接；第一转动体37与第一主体固定连接，第三转动体39与第二主体固定连接，以实现第一主体与第二主体之间的相对转动以及折叠。
在具体实施时，柔性电路板4的固定部43可以与第二转动体38固定连接；具体来说，第二转动体38可以为铁磁性材质，磁吸固定件5能够与第二转动体38进行吸合，并将柔性电路板4的固定部43夹持固定在第二转动体38和磁吸固定件5之间。当然，第二转动体38上也可以对应设置平面结构以提升与磁吸固定件5(或柔性电路板4)之间的贴合面积，以增加磁吸固定件5、柔性电路板4以及第二转动体38之间的相对稳定性。
另外，如图23所示，在本申请提供的一个实施例中，可折叠电子设备中还包括柔性屏幕6(OLED flexible display)；该柔性屏幕6的一部分固定在第一主体1上，另一部分固定在第二主体2上。当第一主体1和第二主体3通过铰链3进行折叠或者转动时，靠近铰链3的柔性屏幕可弯曲形变。其中，柔性电路板4的第一端41可以通过连接器1a与第一主体1侧的柔性屏幕6进行连接，柔性电路板4的第二端42可以与第二主体2上的电器元件进行连接；具体来说，第二主体2上的电器元件可以是印制电路板(pcb circuit boards)、处理器(central processing unit)、电池等部件；当然，柔性电路板4的第一端41还可以是与第一主体1的一侧的电器元件进行连接，柔性电路板4的第二端42与第二主体2的一侧的柔性屏幕进行连接。
应理解，如图24所示，在其他实施例中，也可以在柔性电路板4与铰链3之间设置挡板机构7，以防止柔性电路板4夹在铰链3的缝隙中，对柔性电路板4造成损伤。
以上，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
