请参阅图1和图2，本申请实施例提供的一种电子设备100，可以是手机，也可以是平板电脑，在此不做限定。
电子设备100包括壳组件10和柔性显示装置20。壳组件10形成收容腔10a，柔性显示装置20与壳组件10相连接。电子设备100还可以包括电路板(图未示)和电池(图未示)，电路板和电池均可以设置于壳组件10的收容腔10a(参阅图6所示)内。电路板可以集成电子设备100的处理器、电源管理模块、存储单元和基带芯片等。柔性显示装置20与处理器通信连接，电池能够为柔性显示装置20及电路板上的电子元件供电。当然，电子设备100还可以包括摄像头模组(图未示)，摄像头模组与电路板通信连接，电池能够为摄像头模组供电。可以理解的是，本申请实施方式的电子设备100包括但不限于手机、平板电脑等终端设备或者其它便携式电子设备100。在本申请实施方式中，以手机为例进行说明。
结合图3和图4所示，柔性显示装置20包括柔性屏幕21和伸展机构22，柔性屏幕21具有显示面21a，伸展机构22与柔性屏幕21的背向显示面21a的一侧相连接，用于对柔性屏幕21的展开部分进行支撑。
具体地，柔性屏幕21包括相连接的固定部212和自由部214，自由部214可于第一方向上相对固定部212展开或收拢，确切的说，柔性屏幕21的自由部214能够弯折，从而调整自由部214相对固定部212的展开长度，达到调整柔性屏幕21在第一方向上显示画面的长度(即柔性屏幕21的显示画面的展开长度)。需要说明的是，在一些实施方式中，自由部214在第一方向上可以以卷曲的方向弯折，也可以是在第一方向上以对折的方式弯折，在此不做限定。
伸展机构22与柔性屏幕21的背向显示面21a的一侧相连接，伸展机构22包括第一支撑件221和第二支撑件222，第一支撑件221与固定部212相对固定，第一支撑件221和第二支撑件222可沿第一方向相对运动，以使得自由部214展开或收拢。利用第一支撑件221和第二支撑件222对柔性屏幕21进行支撑。
在本申请实施方式中，两物的位置相对固定即两物在正常情况下不能产生相对运动，位置相对固定的两物可以存在物理上的直接连接，也可以通过中间结构实现间接连接。以固定部212与第一支撑件221为例，固定部212与第一支撑件221的位置相对固定，可以是固定部212与第一支撑件221直接接触，例如采用螺纹紧固件或者卡持等方式实现固定部212与 第一支撑件221的直接固定，也可以是固定部212通过粘胶层、中间连接板等结构实现固定部212与第一支撑件221的间接固定。在一些实施方式中，固定部212可以固定连接于壳组件10，壳组件10与第一支撑件221相对固定，从而使得固定部212与第一支撑件221相对固定。对于固定部212与第一支撑件221之间相对固定的实现方式，在此不再赘述。
继续结合图3和图4所示，自由部214设置有磁体211，第二支撑件222设置有磁吸组件，这里需要说明的是，设置磁吸组件的方式可以是直接将磁吸组件安装于第二支撑件222，也可以是通过中间结构间接地将磁吸组件与第二支撑件222相连，例如，在壳组件10包括第一壳体12和第二壳体14，第二支撑件222与第二壳体14相对固定的实施方式中，可以将磁吸组件安装于第二壳体14，从而利用第二壳体14与第二支撑件22之间的相对固定，实现将磁吸组件与第二支撑件22相连接。对于磁吸组件的设置方式，在此不再赘述，只要磁吸组件能够发挥其相应的作用，且不会干涉柔性显示装置20的伸展或收缩使用需要即可。
具体地，磁吸组件用于磁性吸引磁体211，以将自由部214的至少部分结构吸附于第二支撑件222，使得自由部214与第二支撑件222之间保持良好的贴壁效果，避免自由部214脱离第二支撑件222而出现拱起，因此，通过磁吸组件与磁体211的磁吸配合，提高了柔性屏幕21所显示的画面的整体平整性，提升了用户使用体验。
磁体211采取铁、钴、镍、锰等能够被磁铁吸引的磁性材料以及它们的合金制成，使得磁体211能够被磁吸组件吸引。
磁体211的形状可以是条状，也可以是片状。例如，在一些实施方式中，磁体211包括多个磁性支撑条，多个磁性支撑条沿第一方向间隔排布，且每个磁性支撑条的长度方向均垂直于第一方向，从而磁性支撑条的设置不会对柔性屏幕21在第一方向上的弯折产生干扰，因此，磁性支撑条既可以对柔性屏幕21在垂直于第一方式上产生支撑效果，同时，磁性支撑条被磁吸组件吸附于第二支撑件222时，可以提升第二支撑件222对柔性屏幕21的支撑效果，避免柔性屏幕21拱起，有效地提升了柔性屏幕21的展开部分的画面平整度。
在一些实施方式中，磁体211包括磁性橡胶片，磁性橡胶片贴附于柔性屏幕21的背向显示面21a的一侧，且能够随自由部214弯折。磁性橡胶片即满足与磁吸组件磁性吸附的需要，同时，磁性橡胶片柔性好，能够随自由部214弯折，不影响柔性屏幕21的展开和收拢。
当然，磁体211还可以采取磁性材料制成膜状件，该膜状件可以作为柔性屏幕21的层结构设置在柔性屏幕21中。通过这种结构设置，磁体211即能够适应柔性屏幕21在第一方向上弯折的需要，也可以满足磁吸组件的吸附需要。对于磁体211的形状，在此不再赘述，只要能够适应柔性屏幕21的弯折需要，同时能够被磁吸组件吸引即可。
磁吸组件包括磁铁，磁铁的类型可以为钕铁硼磁铁、钐钴磁铁或铝镍钴磁铁。
在本申请实施方式中，壳组件10与伸缩机构相连接，壳组件10能够适应伸缩机构的第一支撑件221和第二支撑件222相对运动的需要，也就是说，壳组件10不会干涉第一支撑件221和第二支撑件222之间的相对运动。
具体地，在第一支撑件221和第二支撑件222相对运动时，柔性屏幕21从壳组件10展出或收入壳组件10，从而调整柔性屏幕21的显示画面的展开长度。
在一些实施方式中，柔性显示装置20在第一方向上以单侧伸展的方式调整柔性屏幕21的显示画面的展开长度，也可以是在第一方向上以双侧伸展的方式调整柔性屏幕21的显示画面的展开长度。这里需要说明的是，单侧伸展和双侧伸展是针对柔性屏幕21的展开方式而言的，具体地，单侧伸展指的是柔性屏幕21的自由部214在固定部212的其中一侧展开或收拢，这种情况下，可以认为自由部214设置在固定部212的其中一侧。相应地，双侧伸展指的是柔性屏幕21可以在固定部212在第一方向的两侧实现展开或收拢，这种情况下，可以认为柔性屏幕21包括2个自由部214，2个自由部214分别连接于固定部212的两端。
为了便于理解，下面将围绕柔性屏幕21单侧伸展以及双侧伸展对柔性显示装置20的结构做进一步描述。
结合图1至图4所示，在柔性屏幕21单侧伸展的实施方式中，壳组件10包括第一壳体12和第二壳体14，第二壳体14和第一壳体12能够在第一方向上相对运动，从而适应第一支撑件221和第二支撑件222在第一方向上的相对运动，以便对柔性屏幕21的展开部分进行支撑。具体地，伸展机构22位于壳组件10围合的空间内，并支撑柔性屏幕21展开的部位。其中，第一支撑件221与第一壳体12相对固定，第二支撑件222与第二壳体14相对固定，从而在第一壳体12与第二壳体14在第一方向相对运动时，第一支撑件221和第二支撑件222同步运动。
第二壳体14和第一壳体12滑动连接。换言之，第二壳体14能够相对第一壳体12滑动。例如，第一壳体12和第二壳体14中的一者可以设有滑轨，另一者可沿滑轨滑动，以使第一壳体12和第二壳体14能够彼此伸缩运动。
柔性屏幕21连接于第一壳体12和第二壳体14。随着第一壳体12和第二壳体14相对运动，柔性屏幕21的部分结构从壳组件10内展出或收入壳组件10内，以达到调整柔性屏幕21的展开长度的目的。
进一步，第一壳体12能够相对第二壳体14沿第一方向滑动至第一位置和第二位置。结合图1所示，第一壳体12在第一位置时，电子设备100具有相对较小的外形尺寸，便于携带。结合图2所示，第一壳体12在第二位置时，电子设备100可以获得相对较大的显示面21a积，从而获得大屏显示的视觉体验，以提升电子设备100的使用体验。因此，通过这种设置，能够通过第一壳体12和第二壳体14的相对滑动伸缩来调整柔性屏幕21的显示画面的区域。
可以理解的是，在本申请后文的实施方式中，第一位置、第二位置及类似的表述均是指第一壳体12与第二壳体14的相对位置。为简化表述，“第一壳体12位于第一位置”或者“在第一位置时”这种类似的表述是指第一壳体12相对第二壳体14处于第一位置，“第一壳体12位于第二位置”或者“在第二位置时”这种类似的表述是指第一壳体12相对第二壳体14处于第二位置。可理解地，由于第一支撑件221与第一壳体12相对固定，第二支撑件222与第二壳体14相对固定，因此，第一壳体12相对第二壳体14位于第一位置时，第一支撑件221相对第二支撑件222也位于第一位置；相应地，第一壳体12相对第二壳体14位于第二位置时，第一支撑件221相对第二支撑件222也位于第二位置。
结合图1和图2所示，在一些实施方式中，第一壳体12位于第一位置时，柔性屏幕21的显示面21a暴露于壳组件10外的部分大致呈矩形状，其尺寸可以为4.5英寸～7英寸，即与一般的智能手机的显示屏的尺寸相当，以使电子设备100便于携带且使用较为方便。与第一壳体12位于第一位置相比，第一壳体12位于第二位置时，柔性屏幕21的显示面21a更多的暴露于壳组件10，从而呈现更大显示画面，实现大屏显示效果。
结合图5所示，在柔性屏幕21包括2个自由部214的实施方式中，2个自由部214分别连接于固定部212的两端，第一支撑件221在第一方向上的相对两侧均设置有第二支撑件222，其中一个第二支撑件222用于支撑柔性屏幕21的其中一个自由部214，另一个第二支撑件222用于支撑柔性屏幕21的另一个自由部214。该实施方式中，当其中一侧的第二支撑件222相对第一支撑件221沿第一方向运动时，位于该侧的自由部214展开或收拢。当另一侧的第二支撑件222相对第一支撑件221沿第一方向运动时，另一个自由部214展开或收拢。因此，通过这种结构设置，柔性显示装置20可以实现柔性屏幕21的双侧伸展，以增大柔性屏幕21的显示画面的尺寸，获取良好大屏显示效果，相应地，在不需要大屏显示时，可以将柔性显示装置20收拢，提高便携性。
该实施方式中，壳组件10还可以包括第三壳体(图未示出)，第三壳体可相对第一壳体12沿第一方向运动。需要说明的说，第二壳体14和第三壳体分别位于第一壳体12在第一方向上的两侧，并分别与相应侧的第二支撑件222相对固定，这样壳组件10不仅能够适应柔性显示装置20的伸展需要，同时，也能够适应对柔性屏幕21未展出的部分以及伸展机构22 进行收纳的需要，以维持电子设备100整体外观的美感。
在本申请实施方式中，第一支撑件221和第二支撑件222的配合结构具有多种实施方式。第一支撑件221与第二支撑件222彼此滑动连接，或者，第一支撑件221和第二支撑件222设置在一个共同的滑动件上，对于第一支撑件221和第二支撑件222之间的连接方式，在此不作限定。
为了便于理解，下面示例性地结合第一支撑件221和第二支撑件222对伸展机构22的机构做进一步说明。
结合图3和图4所示，第二支撑件222开设有多个插槽2221，多个插槽2221均沿第一方向延伸，且彼此平行地沿第二方向排布，第二方向与第一方向相垂直。第一支撑件221包括脊骨条2211以及与脊骨条2211相连接的多个骨架2212，多个骨架2212呈梳齿状排布，多个骨架2212可移动地插设于多个插槽2221。
需要说明的是，骨架2212与插槽2221作为滑动配合的两个对象，它们在第一支撑件221和第二支撑件222中的设置位置可以互换，确切的说，插槽2221可以是形成于第一支撑件221，相应地，第二支撑件222包括脊骨条2211以及与脊骨条2211相连接的多个骨架2212，从而利用骨架2212与插槽2221的配合，使得第一支撑件221与第二支撑件222可沿第一方向相对运动。
结合图5所示，在第一支撑件221在第一方向上的相对两侧均设置有第二支撑件222的实施方式中，两个第二支撑件222与第一支撑件221的配合结构可以相同，即两个第二支撑件222与第一支撑件221之间的配结构均为上述的插槽2221与骨架2212。示例性地，在一些实施方式中，第一支撑件221在第一方向上的两侧分别设有插槽2221和骨架2212，其中一侧的第二支撑件222设置有与第一支撑件221的插槽2221相配合的骨架2212，另一侧的第二支撑件222设置有与第一支撑件221的骨架2212相配合的插槽2221。再例如，在一些实施方式中，第一支撑件221在第一方向上的相对两侧设置有插槽2221，两个第二支撑件222均包括与插槽2221相配合的骨架2212，或者，第一支撑件221在第一方向上的相对两侧设置有骨架2212，两个第二支撑件222均包括与骨架2212相配合的插槽2221。
需要说明的是，两个第二支撑件222与第一支撑件221的配合结构也可以不相同，只要两个第二支撑件222能够相对第一支撑件221沿第一方向伸缩运动，以满足对柔性屏幕21的2个自由部214的展开部分进行支撑需要即可。
在本申请实施方式中，基于设置在第二支撑件222的磁吸组件对磁体211的磁性引力，将自由部214的至少部分结构吸附于第二支撑件222，使得自由部214展开或收拢时不会拱起，提升了柔性屏幕21的显示画面的平整性。
对于磁吸组件在第二支撑件222中的设置方式具有多种实施方式，下面仅示例性的对磁吸组件的设置方式加以说明，但并非仅限于此。
在一些实施方式中，第二支撑件222开设有安装槽(图未示出)，磁吸组件安装于安装槽内，从而使得磁吸组件与第二支撑件222之间具有良好稳定性，磁吸组件不易脱离第二支撑件222。可以理解地，磁吸组件安装在安装槽内，不会过于突兀，以便第二支撑件222对柔性屏幕21进行良好支撑。第二支撑件222可以采取磁性材料支撑，这样，磁吸组件可以借助自身的磁性对第二支撑件222进行吸引，以增强安装稳定性。在一些实施方式中，磁吸组件可以是通过胶水粘接、螺钉连接等方式与第二支撑件222相连接，以进一步提高磁吸组件在安装槽内的安装稳定性。对于磁吸组件的安装方式，在此不作限定。在其他实施方式中，磁吸组件还可以是其他方式设置于第二支撑件222，例如，第二支撑件222设置有磁化部，磁化部用于充磁以形成磁吸组件。其中，磁化部采取铁、钴、镍、锰等磁性材料制成，以便通过充磁来获得磁吸组件。
需要说明的是，无论磁吸组件包括多个磁铁，还是包括多个磁化部，或者，磁性组件包括多个磁铁和多个磁化部。这些磁铁和磁化部可以是位于同一平面，也可以是位于不同平面。 以磁吸组件包括多个磁铁为例，多个磁铁中的一些磁铁可以是设置在第二支撑件222的朝向柔性屏幕21一侧的表面，另一些磁铁可以是设置在第二支撑件222的背向柔性屏幕21一侧的表面。进一步地，在第二支撑件222开设有安装槽以用于安装磁铁的实施方式中，第二支撑件222的朝向和背向柔性屏幕21的一侧均开设安装槽，以适应在第二支撑件222的相背的两侧安装磁铁的需要。可以理解地，多个磁铁也可以全部安装在第二支撑件222的同一侧，例如，多个磁铁均连接于第二支撑件222的朝向柔性屏幕21的一侧，或者，多个磁铁均连接于第二支撑件222的背向柔性屏幕21的一侧。
相应地，在磁吸组件包括磁化部的实施方式中，磁化部的设置方式可以参考上述磁铁的设置方式，在此不做赘述。
这里需要说明的是，由于磁化部可以通过充磁的方式产生磁性，因此，在加工第二支撑件222时，可以将第二支撑件222的需要形成磁化部的部分填充磁化材料，使得磁化部与第二支撑件222融为一体，这种一体结构的整体稳定性好，且只需要对相应位置的磁化部进行磁化，便能够获得能够吸引磁体211的磁吸组件。
磁化过程中，通过调整磁化的方向，可以便捷的配置不同的磁化部的极性朝向。例如，将一些磁化部的南极朝向显示面21a，将另一些磁化部的南极背向显示面21a，从而使得这些磁化部在特定区域(例如下文中的“磁敏感区域C”)的磁感应强度相互减弱。
具体地，在一些实施方式中，通过对磁吸组件在第二支撑件222中的设置方式进行改进，使得磁吸组件在第二支撑件222中产生的磁场环境不仅有利于提高磁吸组件与柔性屏幕21上的磁体211之间的吸附力，以降低柔性屏幕21发生拱起的风险，而且，降低设置在电子设备100或柔性显示装置20中的磁敏元件的磁干扰。
下面为了便于理解，结合图4所示，以磁吸组件包括多个磁铁为例加以说明。下文中将用于设置磁敏元件的区域称为“磁敏感区域C”。
在一些实施方式中，柔性显示装置20具有至少一个磁敏感区域C，磁敏感区域C与第一支撑件221或第二支撑件222的相对位置固定。可理解地，磁敏感区域C作为设置磁敏元件的区域，磁吸组件在此区域的磁感应强度越低，磁吸组件对磁敏元件产生的磁干扰越小。
磁吸组件的多个磁铁以不同磁极朝向设置，为了便于描述，将其中北极朝向显示面21a的磁铁称为“第一磁铁223”，将其中南极朝向显示面21a的磁铁称为“第二磁铁224”。具体地，磁吸组件包括多个第一磁铁223和多个第二磁铁224，在磁吸组件的磁场环境中，第一磁铁223的北极朝向显示面21a，第一磁铁223的南极背向显示面21a，第二磁铁224的南极朝向显示面21a，第二磁铁224的北极背向显示面21a。
该实施方式中，当柔性显示装置20展开至预设位置时，第一磁铁223与第二磁铁224在磁敏感区域C的磁感应强度相互减弱，这样，第一磁铁223和第二磁铁224在磁敏感区域C的磁感应强度不仅不会叠加，而且相互较弱，使得磁敏感区域C的整体磁感应强度处于低水平，以此尽可能降低设置在磁敏感区域C的磁敏元件受到的磁干扰。在一些实施方式中，第一磁铁223和第二磁铁224在该磁敏感区域C的磁感应强度完全抵消，从而将磁敏感区域C的磁感应强度降低到0，此时，磁敏元件完全不受磁吸组件的磁干扰。
需要说明的是，预设位置为柔性屏幕21完全展开的位置或完全收拢的位置。在一些实施方式中，预设位置为柔性屏幕21完全展开的位置与完全收拢的位置之间的其中一个中间位置，例如，柔性屏幕21展开至最大展开长度的1/10、1/9、1/7、1/6、1/4、1/3或1/2，其中，最大展开长度为柔性屏幕21完全展开时的长度。
在柔性显示装置20设置有磁敏元件的实施方式中，当柔性显示装置20展开至预设位置时，磁敏元件位于柔性显示装置20的磁敏感区域C，磁吸组件在磁敏感区域C的磁感应强度小于或等于磁敏元件能够承受磁场干扰的临界值。假如磁敏元件能够承受磁场干扰的临界值为B，则当柔性显示装置20展开至预设位置时，磁吸组件在磁敏感区域C的磁感应强度小于或等于B。
该实施方式中，在预设位置下，磁吸组件对磁敏元件的磁感应强度在磁敏元件能够承受的范围内，从而磁敏元件可以正常发挥相应的功能。
在一些实施方式中，磁敏元件为地磁传感器，用于检测地球磁场，以便电子设备100实现指南针功能。
在一些实施方式中，结合图6和图7所示，磁敏元件可以为霍尔传感器40，用于检测柔性显示装置20的展开或收拢至预设位置时到位信号，例如，在柔性屏幕21展开至最大展开长度时，霍尔传感器40侦测到位信号，电子设备100的柔性屏幕21将停止展开或收拢。当然，在电子设备100的其他位置设置霍尔传感器40来侦测柔性屏幕21展开至例如1/10、1/9、1/7、1/6、1/4、1/3或1/2等位置时的到位信号。由于位于预设位置下，磁吸组件对磁敏元件的磁感应强度在磁敏元件能够承受的范围内，因此，前述的地磁传感器和霍尔传感器40能够正常的发挥相应的作用。
柔性显示装置20电连接有控制器(图未示出)，控制器电连接有电磁线圈30(参阅图6和图7所示)，当磁吸组件在磁敏感区域C的磁感应强度大于磁敏元件能够承受磁场干扰的临界值时，控制器用于根据磁敏元件检测到的磁吸组件在磁敏感区域C的磁感应强度控制电磁线圈30产生与磁吸组件的磁场方向相反的磁场，从而进一步降低磁敏感区域C的磁感应强度，使得磁敏感区域C的磁感应强度恢复至磁敏元件能够承受磁场干扰的临界值以下。当然，也可以利用电磁线圈30将磁敏感区域C的磁感应强度调整至0，从而使得位于磁敏感区域C的的敏感元件在工作时完全不受磁吸组件的磁干扰。
需要说明的是，电磁线圈30内可以设置铁芯30a，以在电磁线圈30通入同等电流下，具有铁芯30a的电磁线圈30可以产生更大磁场，以利于提高对磁敏感区域C的磁感应强度的调节效率。
在一些实施方式中，多个第一磁铁223在磁敏感区域C的磁感应强度之和的绝对值与多个第二磁铁224在磁敏感区域C的磁感应强度之和的绝对值相等。该实施方式中，多个第一磁铁223和多个第二磁铁224在磁敏感区域C的磁感应强度完全抵消，从而使得磁敏感区域C的磁感应强度为0，这样对应于磁敏感区域C的磁敏元件将不会受到磁吸组件的干扰。
在一些实施方式中，多个第一磁铁223和多个第二磁铁224均为相同规格的磁铁，且第一磁铁223和第二磁铁224的数量相等，第一磁铁223和第二磁铁224成对地以过磁敏感区域C的直线为对称轴呈对称设置。需要说明的是，相同规格的磁铁指的是“尺寸相同”且“表磁大小相等”的磁铁。
为便于理解，结合图8所示，图8中将北极朝向显示面21a的磁铁标识为
将南极朝向显示面21a的磁铁标示为
图8示出了，第一磁铁223和第二磁铁224以对称线o对称设置。其中，对称线o在柔性屏的显示面21a的投影线与显示面21a的边缘在第二方向上相交于第一交点a和第二交点b，第一磁铁223和第二磁铁224连线的中点位于第一交点a和第二交点b连线的中点附近或重合。通过磁场测量仪器沿对称线由第一交点a向第二交点b移动，对磁感应强度进行测量，获得如图9所示的磁感应强度-距离关系线图。从图9中可以看出，在靠近第一交点a处的磁感应强度趋于0，磁场测量仪器从第一交点a向第二交点b移动过程中，磁场测量仪器所测得的磁感应强度逐渐增大，并在第一交点a和第二交点b的中间位置(与第一交点a的距离在1.50mm附近)处出现最大值，然后，在靠近第二交点b时，磁感应强度逐渐减小，最终趋于0。由此可见，在第一磁铁223和第二磁铁224采取磁极相反的方式排布时，就可以在对称线位置上找到磁感应强度趋于0的位置，则将该位置设定为磁敏感区域C，设置在磁敏感区域C的磁敏元件将会不受磁吸组件的磁干扰。
示例性地，结合图10所示，磁敏感区域C到第一交点a的距离为e，e的数值可以根据相应位置的磁场需要进行设置，例如，以图9示出的磁感应强度-距离变化线为例，磁敏感应区域处的磁敏元件能够承受的磁场干扰的临界值为12.5mT时，则在第一交点a和第二交点b 之间满足磁敏感区域C要求的e的取值范围为0mm～1.25mm以及1.75mm～3.50mm。
结合图11所示，这样呈对称设置的第一磁铁223和第二磁铁224可以为多个，确切的说，数量相等的第一磁铁223和第二磁铁224成对地以过磁敏感区域C的直线为对称轴呈对称设置。这样，也可以使得磁敏感应区域的磁感应强度在磁敏元件能够承受磁场干扰的临界值以下。
需要说明的是，多个第一磁铁223和多个第二磁铁224的排布方式不限于上述例举的情形，在一些实施方式中，还可以采取其他排布方式，只要对应敏感区域的磁感应强度在磁敏元件能够承受磁场干扰的临界值以下即可。
下面仅示例性的对第一磁铁223和第二磁铁224的排布方式进行说明。
例如，结合图12所示，在一些实施方式中，在第一方向上，第一磁铁223和第二磁铁224交替排布于第二支撑件222，在垂直于第一方向上，第一磁铁223和第二磁铁224交替排布于第二支撑件222。
在一些实施方式中，e个第一磁铁223构成一个第一磁吸单元，f个第二磁铁224构成一个第二磁吸单元，e，f均为自然数，e大于f。比如，如图13所示，1个第一磁铁223构成一个第一磁吸单元，2个第二磁铁224构成一个第二磁吸单元。
第一磁吸单元在磁敏感区域C的磁感应强度的绝对值与第二磁吸单元在磁敏感区域C的磁感应强度的绝对值相等。通过这种设置，即使第一磁吸单元中的任意一个第一磁铁223在磁敏感区域C的磁感应强度小于第二磁吸单元中的任意一个第二磁铁224在磁敏感区域C的磁感应强度，通过配置不同数量的第二磁铁224与第一磁铁223，使得它们的组合在磁敏感区域C的磁感应强度相互减弱或抵消，以利于降低对磁敏元件的磁干扰。
在一些实施方式中，第三磁吸单元中的任意一个第一磁铁223在磁敏感区域C的磁感应强度大于第四磁吸单元中的任意一个第二磁铁224在磁敏感区域C的磁感应强度。该实施方式中，m个第一磁铁223构成一个第三磁吸单元，n个第二磁铁224构成一个第四磁吸单元，m，n均为自然数，m小于n，第三磁吸单元在磁敏感区域C的磁感应强度的绝对值与第四磁吸单元在磁敏感区域C的磁感应强度的绝对值相等。
结合图14所示，至少1个第一磁铁223和至少1个第二磁铁224规格相同并成对地以过磁敏感区域C的直线为对称轴呈对称设置。需要说明的是，图14仅示意性示出了4组成对设置的第一磁铁223和第二磁铁224以轴对称的方式排布。这些成对设置的第一磁铁223和第二磁铁224的对称轴可以相同，也可以不同，在此不做赘述。
在一些实施方式中，还通过设置吸波件或隔磁件的方式来降低敏感区域的磁感应强度。
示例性地，结合图15所示，多个第二磁铁224对磁敏感区域C的磁感应强度较强，磁吸组件还包括多个吸波件225，多个吸波件225设置于多个第一磁铁223和多个第二磁铁224对磁敏感区域C的磁感应强度较强的一者上，且吸波件225朝向磁敏感区域C所在一侧，以降低磁敏感区域C的磁感应强度。
示例性地，结合图16所示，多个第一磁铁223对磁敏感区域C的磁感应强度较强，磁吸组件还包括多个隔磁件226，多个隔磁件226设置于多个第一磁铁223和多个第二磁铁224对磁敏感区域C的磁感应强度较强的一者上，且隔磁件226朝向磁敏感区域C所在一侧，以降低磁敏感区域C的磁感应强度。
对于吸波件225和隔磁件226的排布方式，可以参考第一磁铁223和第二磁铁224的排布方式，在此不作赘述。
吸波件225的材料可以采取SPCC(一般用冷轧碳素钢薄板及钢带)、磁性薄膜等吸波材料，吸波件225通过改变磁力线的分布方向，进而改变对磁敏感区域C的影响。隔磁件226的材料可以采取硅钢片或坡莫合金等低导磁材料。
再次参阅图6和图7所示，电子设备100设置有牵引件50，牵引件50设置于第二壳体14的远离第一壳体12的一端，在第二壳体14相对第一壳体12从第一位置切换至第二位置 的过程中，牵引件50可以牵引柔性屏幕21变形以使得柔性屏幕21展开于第二壳体14的部分平整。在第二壳体14位于第一位置时，柔性屏幕21的自由部214绕过牵引件50，牵引件50可以将柔性屏幕21的弯曲半径限制在适宜的范围内，以避免弯曲半径过小造成柔性屏幕21的损伤。当然，牵引件50也可以避免柔性屏幕21弯曲半径过大造成电子设备100厚度过大。
在一些实施方式中，牵引件50可为带有凸齿的转轴结构，柔性屏幕21通过啮合等方式与牵引件50相联动。第二壳体14相对第一壳体12滑动时，通过牵引件50带动啮合于牵引件50上的部分柔性屏幕21移动并从壳组件10展出或收入壳组件10内。
需要特别说明的是，在磁体211的形状为条状的实施方式中，可以利用间隔设置的磁体211形成与牵引件50的凸齿相啮合的传动组件，从而使得磁体211不仅能够满足磁吸组件的吸附需要，同时，也能够适应牵引件50与柔性屏幕21啮合联动的需要，从而可以在提升柔性屏幕21的平整性的同时减少结构件的设置数量，有利于电子设备100的轻薄化。
在另一些实施方式中，牵引件50为不附带齿的圆轴。在第二壳体14由第一位置切换至第二位置的过程中，通过牵引件50将贴合于牵引件50上的部分柔性屏幕21撑开，以使更多的柔性屏幕21暴露于壳组件10外侧，并处于平展位置。在这种实施方式中，牵引件50可以转动地设置于第二壳体14，在逐步展开柔性屏幕21的过程中，牵引件50可随柔性屏幕21的移动而转动，以减小柔性屏幕21在展开过程中所受到的阻力，并减小牵引件50与柔性屏幕21的接触部位的磨损。
在一些实施方式中，牵引件50也可固定在第二壳体14上，牵引件50具有光滑的表面。在将柔性屏幕21展开至第二壳体14的过程中，牵引件50通过其光滑的表面与柔性屏幕21可滑动接触。换言之，在这种实施方式中，牵引件50可以和第二壳体14一体成型或者焊接成型，牵引件50可以视为第二壳体14的一部分，柔性屏幕21的自由部214绕过第二壳体14的远离第一壳体12的一端并伸入壳组件10内。
在第二壳体14由第一位置切换至第二位置的过程中，柔性屏幕21可在牵引件50的带动下从第二壳体14展出或收入壳组件10内。可以理解的是，在第一位置和第二位置之间还可以设置多个中间位置，以实现第二壳体14相对第一壳体12在多个中间位置的定位，并使得柔性屏幕21在不同的中间位置具有不同的显示面21a积，从而拓展电子设备100的使用场景。
电子设备100的第一壳体12和第二壳体14的相对运动可以是通过手动方式或电控方式来实现。
例如，采取手动方式时，只需要用户握持第一壳体12和第二壳体14，朝彼此远离的方向移动时，可以将第二壳体14置于第二位置。相应地，在第二壳体14处于第二位置时，如需要收拢电子设备100，只需要将第一壳体12和第二壳体14朝彼此靠近的方向移动即可。
结合图2和图4所示，在采取电控方式时，可以在电子设备100的壳组件10内设置驱动机构60。具体地，驱动机构60设于壳组件10的收容腔10a内，并用于驱使第一壳体12和第二壳体14相对运动，从而第二壳体14带动柔性屏幕21从壳组件10展出或收入壳组件10。
在一些实施方式中，第一壳体12和第二壳体14连接于驱动机构60，并在驱动机构60的带动下相对运动。具体地，驱动机构60具有固定部212和活动部，驱动机构60工作时，活动部能够相对固定部212运动。固定部212与第一壳体12相连接，活动部与第二壳体14相连接，并用于带动第二壳体14相对第一壳体12运动。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不 脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
