Description
本发明实施例涉及但不限于电子设备技术领域，尤其涉及一种电子设备、保护套以及应用于电子设备的翻盖检测的方法。
大屏幕的电子设备越来越普及，已经成为人们生活中的常用品和必需品，在携带和使用过程中难免会把电子设备的屏幕磨损、划伤、碰坏或摔伤，对于屏幕的维修成本是很大的，因此针对大屏幕的保护，一般会使用带有屏幕保护盖的保护套来保护电子设备。
此外，在使用电子设备过程中，一般为省电或避免误操作，相关技术中触摸屏电子设备在无操作一定时间后或按电源键进入休眠状态或口袋模式，这时屏幕会关闭，当需要使用屏幕时，按电源键，从休眠状态唤醒，进入到正常屏显状态。
因此，在使用保护套时，对触摸屏电子设备的操作方式普遍为：首先，打开电子设备保护套，按电源键，触摸屏移动设备进入正常屏显状态；然后，当触摸屏电子设备需要进入休眠状态时，按电源键，合上电子设备保护套。

但是，使用接近传感器检测电子设备保护套面盖的闭合或打开状态，该
方法存在误操作的问题，比如在正常屏显状态时，手或者其他物体遮挡住接近传感器时，触摸屏电子设备就会进入休眠状态；使用霍尔器件，在保护套面盖上安装相应磁铁来检测电子设备保护套面盖的闭合或打开状态的方法时，若耳机或其他带磁铁的设备接近电子设备的霍尔器件工作范围内，就会带来误检测，使电子设备进入休眠模式或口袋模式，进而导致电子设备不能正常工作。

下面将参照附图详细地描述本发明的示例性实施例。
实施例一
本实施例提供了一种电子设备，如图1所示，包括具有显示屏幕的设备本体20，该设备本体20包括：
至少两个霍尔器件，第一霍尔器件21设置为感应到S极磁场的接近状态达到第一预设阈值时，发出第一信号；以及设置为感应到S极磁场的远离状态达到第二预设阈值时，发出第二信号；第二霍尔器件22设置为感应到N极磁场的接近状态达到第三预设阈值时，发出第三信号；以及设置为感应到N极磁场的远离状态达到第四预设阈值时，发出第四信号；以及
控制器23，每一所述霍尔器件分别与所述控制器23电连接；所述控制器23设置为当接收到所述第一信号和所述第三信号时，发出屏幕关闭指令；当接收到所述第二信号和所述第四信号时，发出屏幕打开指令。
其中，霍尔器件对于S极磁场和N极磁场的接近状态和远离状态的感应，可通过S极磁场和N极磁场的磁通量的变化情况来实现。其中，所述第一霍尔器件21感应到S极磁场的磁通量增多且所述S极磁场的磁通量大于第一预设阈值时，发出第一信号；感应到S极磁场的磁通量减少且所述S极磁场的磁通量小于第二预设阈值时，发出第二信号；第二霍尔器件22感应到N极磁场的磁通量增多且所述N极磁场的磁通量大于第三预设阈值时，发出第三信号；感应到N极磁场的磁通量减少且所述N极磁场的磁通量小于第四预设阈值时，发出第四信号。
因此，本发明实施例的电子设备，只有霍尔器件同时检测到S极磁场和N极磁场同时变化时，控制器23才会发出屏幕关闭指令和屏幕打开指令，从而控制设备本体20的显示屏幕关闭或打开。即，若具有磁性的其他设备接近该电子设备时，设备本体20内部的霍尔器件只能检测到S极或N极一个极性的磁场的变化情况，则控制器23判断此种情况属于外界干扰，并不会给予处理，因此不会造成电子设备的误操作。
其中，第一预设阈值和第三预设阈值均代表磁场接近霍尔器件达到一定状态，第二预设阈值和第四预设阈值均代表磁场远离霍尔器件达到一定状态。因此，所述第一预设阈值等于所述第三预设阈值，所述第二预设阈值等于所
述第四预设阈值。根据第一霍尔器件和第二霍尔器件位置的差异，第一预设阈值也可以不等于第三预设阈值，第二预设阈值也可以不等于第四预设阈值。
其中，所述第一信号和所述第三信号均为由高电平到低电平的跳变信号，所述第二信号和所述第四信号均为由低电平到高电平的跳变信号，从而有利于控制器23在接收到第一信号、第三信号、第二信号及第四信号时，便于对此信号进行处理，且易于实现。
可选地，如图2和图3(图中所示霍尔器件和磁铁位置仅为示例)所示，所述电子设备还包括一保护套，所述保护套包括：
设置为与所述设备本体20固定连接的连接部11和设置为保护所述显示屏幕的面盖12，所述面盖12与所述连接部11可转动连接，所述面盖12上设有至少两块磁铁，且所述磁铁的数量与所述设备本体20上的所述霍尔器件的数量相同；
其中，所述面盖12覆盖在所述显示屏幕上时，其中的第一磁铁121设置于所述第一霍尔器件21对应所述面盖12的位置上，第二磁铁122设置于所述第二霍尔器件22对应所述面盖12的位置上；且所述第一磁铁121的S极相较于N极靠近所述显示屏幕，所述第二磁铁122的N极相较于S极靠近所述显示屏幕。
其中，所述保护套还包括一弯折部13，且所述面盖12与所述连接部11通过所述弯折部13可转动连接，使得面盖12可绕弯折部13翻转，进而可将面盖12打开，或闭合覆盖在显示屏幕上。
本发明实施例的电子设备，增加一包括与设备本体20内部的霍尔器件相对应的磁铁的保护套，使得在保护套的面盖12打开时，设备本体20的显示屏幕处于打开状态，面盖12闭合时，显示屏幕处于关闭状态。
其基本原理如图4所示，面盖12内部的第一磁铁121对应与设备本体20内部的第一霍尔器件21，第二磁铁122对应与第二霍尔器件22，第一霍尔器件21的信号输出端Out1接控制器23的一信号接收端，第二霍尔器件22的信号输出端Out2接控制器23的另一信号接收端。
因此，当用户打开保护套的面盖12时，面盖12内的N到S方向的第一
磁铁121逐渐远离第一霍尔器件21，S到N方向的第二磁铁122逐渐远离第二霍尔器件22，使得第一霍尔器件21感应到第一磁铁121的S极磁场的磁通量减少，第二霍尔器件22感应到第二磁铁122的N极磁场的磁通量减少。其中，对于磁通量的多少可通过磁通密度来表示，如图6所示，当S极磁场的磁通量小于第二预设值BrpS时，第一霍尔器件21发出由低电平到高电平跳变的第二信号；如图7所示，当N极磁场的磁通量小于第四预设阈值BrpN时，第二霍尔器件22发出由低电平到高电平跳变的第四信号，若控制器23同时收到第二信号和第四信号时，发出屏幕打开指令。
当用户闭合保护套的面盖12时，面盖12内的N到S方向的第一磁铁121逐渐接近第一霍尔器件21，S到N向的第二磁铁122逐渐接近第二霍尔器件22，使得第一霍尔器件21感应到第一磁铁121的S极磁场的磁通量增多，第二霍尔器件22感应到第二磁铁122的N极磁场的磁通量增多。如图6所示，当S极磁场的磁通量大于第一预设值BopS时，第一霍尔器件21发出由高电平到低电平跳变的第一信号；如图7所示，当N极磁场的磁通量大于第三预设阈值BopN时，第二霍尔器件22发出由高电平到低电平跳变的第三信号，若控制器23同时收到第一信号和第三信号时，发出屏幕关闭指令。
可选地，所述第一磁铁121和所述第二磁铁122均位于所述面盖12上远离所述弯折部13的一侧，所述第一磁铁121的N极朝向的方向垂直于所述面盖12的外表面，所述第二磁铁122的S极朝向的方向垂直于所述面盖12的外表面。因此，当面盖12覆盖在显示屏幕上时，第二霍尔器件22与第二磁铁122的位置关系如图5所示，即此时第二霍尔器件22的上表面被第二磁铁122的磁力线穿入。
实施例二
本实施例提供了一种保护套，应用于上述所述的电子设备，如图2所示，所述保护套包括：
设置为与所述设备本体20固定连接的连接部11和设置为保护所述显示屏幕的面盖12，所述面盖12与所述连接部11可转动连接，所述面盖12上设有至少两块磁铁，且所述磁铁的数量与所述设备本体20上的所述霍尔器件的
数量相同；
其中，所述面盖12覆盖在所述显示屏幕上时，其中的第一磁铁121设置于所述第一霍尔器件21对应所述面盖12的位置上，第二磁铁122设置于所述第二霍尔器件22对应所述面盖12的位置上；且所述第一磁铁121的S极相较于N极靠近所述显示屏幕，所述第二磁铁122的N极相较于S极靠近所述显示屏幕。
可选地，所述保护套还包括一弯折部13，所述面盖12与所述连接部11通过所述弯折部13可转动连接。当然可以理解的是，本发明实施例的保护套的连接部11与面盖12之间可转动连接方式并不限于此。
可选地，所述第一磁铁121和所述第二磁铁122均位于所述面盖12上远离所述弯折部13的一侧，所述第一磁铁121的N极朝向的方向垂直于所述面盖12的外表面，所述第二磁铁122的S极朝向的方向垂直于所述面盖12的外表面。第一磁铁121和第二磁铁122在面盖12内的此种布置方式，使得在面盖12打开和闭合的行程之内，磁通量的变化范围更大，从而有利于霍尔器件对磁通量变化的检测。
本发明实施例的保护套与内部设有霍尔器件的电子设备配套使用，能够防止外界非保护套的面盖12闭合引起的磁场变化导致保护套闭合模式误检测，从而避免了相关技术中的误操作问题。

综上所述，本发明实施例的翻盖检测的方法，应用于设有至少两个霍尔器件的电子设备，能够防止外界非电子设备保护套的面盖12闭合引起的磁场变化导致保护套闭合模式误检测，从而避免了相关技术中的误操作问题。
