下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行 清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的一种电子设备及其折叠角度检测方法进行详细地说明。本申请实施例提供的电子设备为可折叠电子设备，具有折叠屏，该折叠屏可以分为至少两部分，即第一部分11和第二部分12，第一部分11和第二部分12可以通过弯折部13连接，进而实现折叠，该弯折部13可以视为两个部分的折叠线。本申请实施例提供的电子设备基于电涡流原理实现折叠角度检测功能。该折叠屏可以为柔性屏，在折叠过程中柔性屏的背离显示面的一侧会产生一定形变，将涡流传感器贴合设置在折叠屏的背面，当折叠屏角度发生变化时，涡流传感器内部的金属片211会发生形变，从而影响涡流传感器的输出结果，可以检测出电子设备的折叠角度的变化。
图1为本申请实施例提供的一种电子设备。如图1所示，该电子设备可以包括折叠屏，折叠屏包括第一部分11、第二部分12和弯折部13，第一部分11和第二部分12通过弯折部13连接，该电子设备还可以包括：设置于折叠屏的第一涡流传感器21；第一涡流传感器21包括金属片211和线圈模组212，其中，金属片211贴合设置与折叠屏；线圈模组212与金属片211非接触设置，金属片在线圈模组作用下向外辐射磁场。
其中，在第一部分11和第二部分12相对转动的情况下，金属片211发 生形变，线圈模组212中的感应电压变化量与折叠屏的折叠角度相关。
其中，第一涡流传感器21可以设置于折叠屏的不同位置，例如第一部分背离显示面的一侧、与显示面相邻的侧边、弯折部背离显示面的一侧等等，只要可以感应到折叠屏弯折的位置均可。
在本申请实施例中，公开了一种电子设备，该电子设备包括折叠屏，折叠屏包括第一部分、第二部分和弯折部，第一部分和第二部分通过弯折部连接，电子设备还包括设置于折叠屏的第一涡流传感器，第一涡流传感器包括金属片和线圈模组，金属贴片贴合设置于折叠屏；金属片与线圈模组非接触设置，金属片在线圈模组作用下向外辐射磁场，在第一部分和第二部分相对转动的情况下，金属片发生形变，线圈模组中的感应电压变化量与折叠屏的折叠角度相关。在第一部分和第二部分相对转动的情况下，贴合于折叠屏的金属片发生形变，金属片向外辐射的磁场发生变化，线圈模组中产生的感应电压发生变化，感应电压变化量则与折叠屏的折叠角度相关。本申请实施例通过一个涡流传感器即可检测出折叠屏角度的变化，使得测量过程方便、简单，涡流传感器的尺寸较小，可以节省电子设备的空间。
在本申请的一个可能的实施方式中，该电子设备还可以包括与第一涡流传感器连接的处理器，该处理器可以根据感应电压的变化量，确定折叠屏的折叠角度。
本申请实施例中，采用单独的处理器确定折叠屏的折叠角度，使得处理速度更快。在其他实施例中，也可以采用电子设备的处理器来确定折叠屏的折叠角度，以便节省空间。
在本申请的一个可能的实施方式中，线圈模组212包括激励线圈2121和感应线圈2122，激励线圈2121和感应线圈2122中的一个套设于另一者之外。
也就是，可以采用两个线圈分别产生激励磁场和感应电压，使得两个线圈产生和感应的数据更加准确。
为了更好的接收涡流感应磁场，本申请实施例中采用外部是激励线圈2121，内部是感应线圈2122的结构。
在本申请的一个可能的实施方式中，第一涡流传感器21可以设置于第一部分11的背离显示面的一侧；或第一涡流传感器21可以设置于弯折部的背离显示面的一侧。
相应的，第一涡流传感器21也可以设置于第二部分12的背离显示面的一侧。
在本申请实施例中，将第一涡流传感器21设置于折叠屏的背离显示面的一侧，可以使得第一涡流传感器21的安装难度较低，且连接可靠性更好，第一涡流传感器21中的金属片211的各处的形变量较为均匀，测得的数据更加精确。
如图2所示，为本申请实施例提供的一种涡流传感器的结构示意图，如图2所示，该第一涡流传感器21还可以包括：支撑件213。该支撑件213用于将线圈模组212支撑在金属片211背离第一折叠屏11的显示面的一侧。
具体地，如图2所示，涡流传感器的支撑件213的侧视图可以是H型结构件，金属片211设置在H型的下部分，即支撑件213支撑在金属片211上，线圈模组212设置在H型的上部分，以使金属片211和线圈模组212间隔设置，线圈产生的磁场可以覆盖到金属片211，使得金属片211产生涡旋状电流，当金属片211发生形变，例如金属片211在折叠屏展开或折叠时被拉伸或压缩，使得金属片211的导电率发生变化，此时感应线圈中的感应电压也会发生变化，并通过线圈引线214将电压输出到处理器，可以通过感应线圈的变化检测出折叠屏的折叠角度的变化，进而可以准确测量出折叠角度。
其中，金属片211可以是铜片、金片等，但考虑到成本等问题，一般采用铜片。
涡流传感器实现折叠屏角度检测的工作原理示意图如图3所示。当涡流传感器的激励线圈2121通过交变电流I
1后，会在激励线圈2121附近产生交 变磁场H
1，该磁场经过金属片211时，金属片211就会产生蜗旋状的电流I
2，该涡流会产生向外辐射的涡流磁场H
2，从而在感应线圈2122中产生感应电压。产生的涡流磁场是和金属片211的形变量相关，当折叠屏手机弯折时，金属片211的发生形变，从而引起涡流磁场变化，最终导致感应输出结果改变，即实现了折叠屏角度检测功能。
如图4所示，为本申请实施例提供的另一种电子设备，如图4所示，该电子设备还可以包括：与处理器连接的第二涡流传感器22。该第二涡流传感器22设置于第二部分12的背离显示面的一侧。
具体地，该第二涡流传感器22的结构与第一涡流传感器21的结构相同，由于在上述实施例中已详细描述，考虑到文本简洁，本申请实施例中不再赘述。
在本申请实施例中，利用两个涡流传感器可以辅助用户展开或折叠电子设备，使得用户在使用时更加方便，增强用户体验。
也就是，在交流激励电压的基础上叠加偏置电压以产生吸力或斥力，辅助功能涡流激励电压，在折叠电子设备的过程中，在两个涡流传感器施加反向的偏置电压，进而激励出反向的偏置磁场，从而产生吸力，并且在折叠电子设备时，继续产生吸力，起到阻回弹的作用；当展开电子设备的过程中，在两个涡流传感器施加同向的偏置电压，进而激励出同向的偏置磁场，从而产生斥力。辅助功能的开启，减少了用户在展开和折叠电子设备所施加的力量，更好地辅助用户操作使用具有折叠屏的电子设备，如折叠屏手机。
进一步地，第二涡流传感器22与第一涡流传感器21沿弯折部13对称设置。如图4所示，第一涡流传感器21和第二涡流传感器22沿弯折部13对称设置，可以在折叠屏折叠时更好地发挥相吸或相斥的作用。
其中，对称设置是指在电子设备的折叠屏完全展开的情况下，并且将第二涡流传感器22与第一涡流传感器21作为质点，两个质点沿弯折部13对称。当电子设备的折叠屏处于非完全展开，如展开一定角度或完全折叠，两个涡 流传感器的连线的垂线所在的面过弯折部13，因此可以更好的辅助折叠屏的展开或折叠。
在本申请的一个可能的实施方式中，在第一部分11背离弯折部13的一端与第二部分12背离弯折部13的一端相互靠近的情况下，第一涡流传感器21和第二涡流传感器22工作与反向的偏置电压；在第一部分11背离弯折部13的一端与第二部分12背离弯折部13的一端相互远离的情况下，第一涡流传感器21和第二涡流传感器22工作与同向的偏置电压。
在本申请实施例中，可以在涡流传感器产生的激励电压的基础上叠加偏置电压以产生吸力或斥力，辅助涡流激励电压，当检测到第一部分11背离弯折部13的一端与第二部分12背离弯折部13的一端相互靠近，即折叠角度变小时，即折叠电子设备的过程，在两个涡流传感器上施加反向的偏置电压，进而激励出反向的偏置磁场，从而产生吸力，并且在折叠屏完全折叠时，继续产生吸力，起到阻回弹的作用；当检测到第一部分11背离弯折部13的一端与第二部分12背离弯折部13的一端相互远离，即折叠角度变大时，即展开电子设备的过程，在两个涡流传感器上施加同向的偏置电压，进而激励出同向的偏置磁场，从而产生斥力。该辅助功能的开启，可以减少用户在展开和折叠该折叠屏电子设备所施加的力量，更好地辅助用户操作使用折叠屏电子设备。
本申请实施例还提供了一种电子设备的折叠角度检测方法，该电子设备包括折叠屏。如图5所示，该电子设备的折叠角度检测方法可以包括：步骤S501至步骤S502所示的内容。
在步骤S501中，获取设置于折叠屏的第一涡流传感器的感应电压变化量。
在步骤S502中，根据感应电压变化量，确定折叠屏的折叠角度。
在本申请实施例中，首先获取设置于折叠屏的第一涡流传感器的感应电压变化量，然后根据感应电压的变化量，确定折叠屏的折叠角度。本申请实 施例通过设置于折叠屏的涡流传感器即可检测出折叠屏的折叠角度的变化，使得测量过程方便、简单，而且涡流传感器的尺寸较小，可以节省电子设备的空间。
在本申请的一个可能的实施方式中，折叠屏包括第一部分、第二部分和弯折部，第一涡流传感器设置于第一部分的背离显示面的一侧，第二涡流传感器设置于第二部分的背离显示面的一侧；该电子设备的折叠角度检测方法还可以包括以下步骤。
在第一部分背离弯折部的一端与第二部分背离弯折部的一端相互靠近的情况下，向第一涡流传感器和第二涡流传感器施加反向的第一偏置电压；在第一部分背离弯折部的一端与第二部分背离弯折部的一端相互远离的情况下，向第一涡流传感器和第二涡流传感器施加同向的第一偏置电压。
其中，第一涡流传感器与第二涡流传感器沿弯折部对称设置。
在本申请实施例中，可以在涡流传感器产生的激励电压的基础上叠加偏置电压以产生吸力或斥力，辅助功能涡流激励电压，当检测到第一部分11背离弯折部13的一端与第二部分12背离弯折部13的一端相互远离，即折叠角度变大时，即展开电子设备折叠屏的过程，在两个涡流传感器上施加同向的第一偏置电压，进而激励出同向的偏置磁场，从而产生斥力，同样的，当检测到第一部分11背离弯折部13的一端与第二部分12背离弯折部13的一端相互靠近，即折叠角度变小时，即折叠电子设备折叠屏的过程，在两个涡流传感器上施加反向的偏置电压，进而激励出反向的第一偏置磁场，从而产生吸力，并且在折叠屏完全折叠时，继续产生吸力，起到阻回弹的作用。该辅助功能的开启，可以减少用户在展开和折叠该折叠屏电子设备所施加的力量，更好地辅助用户操作使用折叠屏电子设备，如折叠屏手机。
其中，在两个涡流传感器上施加的第一偏置电压的大小可以相同，也可以不同，具体地，可以根据涡流传感器的位置，线圈的大小等确定。
在本申请的一个可能的实施方式中，该电子设备的折叠角度检测方法还 可以包括以下步骤。
在第一部分背离弯折部的一端与第二部分背离弯折部的一端相互靠近的角度大于或等于第一预设角度的情况下，向第一涡流传感器和第二涡流传感器施加反向的第二偏置电压；在第一部分背离弯折部的一端与第二部分背离弯折部的一端相互远离的角度大于或等于第二预设角度的情况下，向第一涡流传感器和第二涡流传感器施加同向的第二偏置电压。
其中，第二偏置电压大于第一偏置电压。
在本申请实施例中，通过在第一涡流传感器和第二涡流传感器上施加比第一偏置电压更大的第二偏置电压，可以进一步减少用户在使用电子设备进行屏幕的折叠和展开时对电子设备施加的力，也就是，只要用户在展开或折叠该折叠屏时，给电子设备一个初始力，当系统检测折叠屏达到一定角度后，用户无需再施加作用力，通过第一涡流传感器和第二涡流传感器的斥力或吸力即可自动实现折叠屏的展开或折叠，进一步提升用户体验。
可选地，本申请实施例还提供了一种电子设备的折叠角度检测装置，该装置可以包括：获取模块和确定模块。
具体地，该获取模块，用于获取设置于所述折叠屏的第一涡流传感器的感应电压变化量；该确定模块，用于根据所述感应电压变化量，确定所述折叠屏的折叠角度。
在本申请实施例中，首先获取模块获取设置于折叠屏的第一涡流传感器的感应电压变化量，然后确定模块根据感应电压的变化量，确定折叠屏的折叠角度。本申请实施例通过设置于折叠屏的涡流传感器即可检测出折叠屏的折叠角度的变化，使得测量过程方便、简单，而且涡流传感器的尺寸较小，可以节省电子设备的空间。
在本申请的一个可能的实施方式中，该装置还可以包括：第一施加模块和第二施加模块。
具体地，第一施加模块，用于在第一部分背离弯折部的一端与第二部分背离弯折部的一端相互靠近的情况下，向第一涡流传感器和第二涡流传感器施加反向的第一偏置电压；该第二施加模块，用于在第一部分背离弯折部的一端与第二部分背离弯折部的一端相互远离的情况下，向第一涡流传感器和第二涡流传感器施加同向的第一偏置电压；其中，第一涡流传感器与第二涡流传感器沿弯折部对称设置。
在本申请的一个可能的实施方式中，该装置还可以包括：第三施加模块和第四施加模块。
