Description

保护套和带有保护套的设备
本申请基于申请号为201410302987.2、申请日为2014/6/27的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本公开涉及电子设备配件领域，特别涉及一种保护套和带有保护套的设备。
背景技术
现有的智能手机和平板电脑等电子设备的显示屏幕越来越大，用户在使用时，为了保护电子设备的屏幕，通常会为电子设备加一个保护套，并同时可以利用保护套实现锁屏和唤醒的功能。
通常，为了实现锁屏和唤醒电子设备的功能，在电子设备中设置有霍尔传感器，同时在保护套上设置一块磁铁，使得在闭合保护套时，保证霍尔传感器处于该磁铁的磁场中。为了保证霍尔传感器能够在磁铁的作用下进行开关，需要对霍尔传感器和磁铁之间的相对位置有较高要求。在一种情况下，磁铁与霍尔传感器在电子屏的横向方向上相距一定距离，这样，在折合保护套之后，如果皮套能够左右移动，霍尔传感器可能就不会被磁铁的磁力线穿过。此时，通常会采用增强磁铁的磁场强度的方式来保证在保护套左右移动时，霍尔传感器仍能够被磁铁的磁力线穿过。
发明人在实现本公开的过程中，发现相关技术至少存在如下缺陷：由于磁铁强度的增加会影响电子罗盘(compass)的稳定性，即电子罗盘在感受到磁铁的磁场时，精度会受到影响。
发明内容
为了解决相关技术中增强的磁铁强度会影响电子罗盘的稳定性的问题，本公开提供一种保护套和带有保护套的设备。所述技术方案如下：

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
文中所讲的“电子设备”可以是智能手机、平板电脑、智能电视、电子书阅读器、MP3播放器(Moving Picture Experts Group Audio Layer III，动态影像专家压缩标准音频层面3)、MP4(Moving Picture Experts Group Audio Layer IV，动态影像专家压缩标准音频层面4)播放器、膝上型便携计算机、智能相机或智能摄像机等等。
为了能够保证电子设备中的霍尔传感器在保护套闭合后实现控制电子设备待机的功能，通常会在保护套中设置一块磁铁，且该磁铁的磁力线在保护套闭合后可以穿过该霍尔传感器。
具体请参见图1A所示，其是根据一示例性实施例示出的一种带有保护套的设备以及保护套闭合时的示意图。在图1A中，保护套a2上设置有磁铁a22，电子设备a4上设置有霍尔传感器a42，其中磁铁a22和霍尔传感器H的相对位置被设置为：当保护套a2闭合时(即保护套a2覆盖在电子设备a4的显示屏上)，磁铁a22在电子设备上的投影与霍尔传感器H形成的直线与电子设备的横向平行，换句话说，当保护套a2闭合时，磁铁a22在电子设备上的投影与霍尔传感器H在电子设备a4的横向上对齐，这里磁铁a22位于霍尔传感器H的左侧。
由于可以对横向上对齐的磁铁a22与霍尔传感器H之间的距离进行设置，使得磁铁a22的磁力线在闭合保护套a2时可以穿过霍尔传感器H。请参见图1B所示，其是图2A中保护套闭合后磁铁的磁力线穿过霍尔传感器时的示意图，磁铁a22的磁力线(即从磁铁a22的N极到S极的磁力线)可以穿过霍尔传感器H。
而由于磁铁a22设置在保护套a2的固定位置上，霍尔传感器H设置在电子设备a4的固定位置上，因此当保护套a2在闭合后发生左右移动时，磁铁a22和霍尔传感器H之间的相对位置则发生变化，比如，位于霍尔传感器H左侧的磁铁a22向左移动，则磁铁a22和霍尔传感器H之间的距离变远，请参见图1C所示，其是图1A中保护套闭合后磁铁的磁力线未穿过霍尔传感器时的示意图，此时容易导致磁铁a22的磁力线不再穿过霍尔传感器H。
易于思及的是，为了在保护套a2移动时，磁铁a22的磁力线仍能够继续穿过霍尔传感器H，则可以加强磁铁a22的磁场，但增强的磁场容易对电子设备a4中的电子罗盘产生较大的影响，使得精确度下降。
因此需要对图1A中的保护套进行改进，改进后的保护套中可以设置有包含至少两块磁铁的磁体，其中至少一块磁铁的磁力线在保护套覆盖在电子设备的显示屏上时穿过霍尔传感器。
在一种可能的实现方式中，磁体可以包含有第一磁铁和第二磁铁，第一磁铁和第二磁铁被设置为：在保护套覆盖电子设备的显示屏上时，第一磁铁与第二磁铁在显示屏上的投影与霍尔传感器位于同一个条直线上，且第一磁铁的投影和第二磁铁的投影分别对称位于霍尔传感器的两侧。其中，为了避免保护套左右移动时对穿过霍尔传感器的磁力线的影响，在保护套覆盖在电子设备的显示屏上时，第一磁铁和第二磁铁所形成的直线可以设置为与显示屏的横向平行；为了避免保护套在上下移动时对穿过霍尔传感器的磁力线的影响，第一磁铁和第二磁铁所形成的直线可以设置为与显示屏的纵向平行。
举例来讲，请参见图2A所示，其是根据另一示例性实施例示出的一种带有保护套的设备以及保护套闭合时的示意图。在图2A中，保护套b2中设置有第一磁铁b22和第二磁铁b24，电子设备b4中设置有霍尔传感器H，当保护套b2正向覆盖在电子设备b4的显示屏上时，也即第一磁铁b22和第二磁铁b24的投影分别位于霍尔传感器H的两侧时，请参见图2B所示，其是图2A中保护套闭合后第一磁铁和第二磁铁的磁力线均穿过霍尔传感器时的示意图，图2B中第一磁铁b22和第二磁铁b24的磁力线均穿过霍尔传感器H。
再举例来讲，当图2A中的保护套b2在覆盖电子设备b4的显示屏上并向左移动时，即第一磁铁b22远离霍尔传感器H，第二磁铁b24更加靠近霍尔传感器，请参见图2C所示，其是图2A中保护套闭合后第二磁铁的磁力线穿过霍尔传感器时的示意图，此时，由于第一磁铁b22远离了霍尔传感器H，因此第一磁铁b22的磁力线不再穿过霍尔传感器，但同时由于第二磁铁b24更加靠近霍尔传感器，因此，第二磁铁b24的磁力线仍旧会穿过霍尔传感器H。
还举例来讲，当图2A中的保护套b2在覆盖电子设备b4的显示屏上并向右移动时，即第一磁铁b24更加靠近霍尔传感器H，第二磁铁b24远离霍尔传感器H，请参见图2D所示，其是图2A中保护套闭合后第一磁铁的磁力线穿过霍尔传感器时的示意图，此时，由于第二磁铁b24远离了霍尔传感器H，因此第二磁铁b24的磁力线不再穿过霍尔传感器，但同时由于第一磁铁b22更加靠近霍尔传感器，因此，第一磁铁b22的磁力线仍旧会穿过霍尔传感器H。
很显然，在保护套覆盖在电子设备的显示屏上时，第一磁铁和第二磁铁的投影所形成的直线与该显示屏横向可以呈任意角度。比如图2E，其是根据一示例性实施例示出的在保护套闭合后两块磁铁与霍尔传感器之间所呈现的相对位置关系的示意图，其中第一磁铁b22和第二磁铁b24在显示屏P上的投影所形成的直线L与显示屏P的横向呈一定角度，该角度可以为0度，即直线L平行于显示屏P的横向方向；该角度可以为90度，即直线L平行于显示屏P的纵向方向；该角度还可以为大于0度且小于90度。
在另一种可能的实现方式中，磁体还可以包括至少两对磁铁，每对磁体被设置为：在保护套覆盖在电子设备的显示屏上时，每对磁铁在显示屏上的投影对称位于霍尔传感器两侧。可选的，第一对磁铁所形成的直线与第二对磁铁所形成的直线之间的最小夹角大于0，其中，第一对磁铁和第二对磁铁是磁体中的任意两对磁铁。也就是说，磁体可以包含偶数块(比如2块、4块、6块等)磁铁，在保护套覆盖在电子设备的显示屏上时，保护套中的每对磁铁的投影对称地位于霍尔传感器的两侧，这样保护套在每对磁铁的投影所在直线上移动时，都能够保证该对磁铁中至少一个磁铁的磁力线穿过霍尔传感器。很显然，对于每对磁铁均可以参考图2B、图2C和图2D
举例来讲，请参见图3所示，其是根据一示例性实施例示出的在保护套闭合后四块磁铁与霍尔传感器之间所呈现的相对位置关系的示意图，其中，磁体包括成对的第一磁铁a1和第二磁铁a2以及成对的第三磁铁a3和第四磁铁a4，在保护套闭合后，第一磁铁a1和第二磁铁a2的投影分别位于霍尔传感器H的左右两侧，也即，第一磁铁a1和第二磁铁a2的投影所形成的指向L1与显示屏P的横向平行；第三磁铁a3和第四磁铁a4的投影分别位于霍尔传感器H的上下两侧，也即，第三磁铁a3和第四磁铁a4的投影所形成的指向L2与显示屏P的纵向平行。很显然，直线L1和直线L2还可以与显示屏P的横向呈其他的角度。
综上所述，本公开实施例提供的保护套和带有保护套的设备，通过在保护套中设置至少两块磁铁，使得当保护套覆盖在显示屏上并移动时，这两块磁铁中总有至少一块磁铁的磁力线穿过电子设备中的霍尔传感器；解决了相关技术中增强的磁铁强度会影响电子罗盘的稳定性的问题；由于在保护套覆盖在显示屏上时，设置的至少两块磁铁中总会有至少一块磁铁的磁力线穿过电子设备中的霍尔传感器，因此在不增强磁铁强度的情况下，如果保护套发生移动，霍尔传感器仍能够被其中一块磁铁的磁力线穿过，达到了可以有效保证锁屏和唤醒时的准确性的效果。
