具体实施方式
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，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。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折叠结构进行详细地说明。
请参见图1至图6，图1至图6为本申请实施例提供的不同折叠状态、不同视角的折叠结构的结构示意图，如图1、图2和图3所示，折叠结构10包括：第一壳体11、第二壳体12、弹性连接部件13和压力检测部件14，其中，
第一壳体11和第二壳体12通过弹性连接部件13连接，且第一壳体11可相对第二壳体12转动；
压力检测部件14与弹性连接部件13连接，用于检测弹性连接部件13的压力值。
本申请实施例中，如图1和图2所示，折叠结构10包括可相对转动的两个壳体，即第一壳体11和第二壳体12，又如图3所示，第一壳体11和第二壳体12可通过弹性连接部件13连接，使得第一壳体11和第二壳体12可完全展开成一块大屏幕，以享受大屏操作体验，也可完全折叠成一个壳体大小的屏幕，以便收纳。需说明的是，第一壳体11可以是折叠结构10的两个壳体中的任一壳体，第二壳体11则相应为折叠结构10的两个壳体中的另一壳体。
为了能对折叠结构10的折叠角度进行检测，以保证后续能够基于折叠角度实现相关交互功能，还可以加入用于检测弹性连接部件13在不同活动状态下的压力值的压力检测部件14，具体地，压力检测部件14可以设置在弹性 连接部件13的活动末端，压力检测部件14也可依附于弹性连接部件13设置，例如，可以在折叠结构10的某一壳体如第一壳体11中设置压力检测部件14，用于检测不同折叠状态下弹性连接部件13所承受的压力值，进而根据压力值，确定对应的折叠角度，也即实现基于压力检测部件14检测到的压力值来确定折叠结构10的折叠角度。
可选地，如图3所示，弹性连接部件13的第一端131与压力检测部件14连接，弹性连接部件13的第二端132设置于第二壳体12。
即一种实施方式中，如图3所示，弹性连接部件13的一端如第一端131与压力检测部件14连接，弹性连接部件13的另一端如第二端132设置在第二壳体12中，弹性连接部件13的第二端132可以为其固定末端，即第二端132在折叠结构10的折叠运动中是保持固定不动的，弹性连接部件13的第一端131则可以在折叠运动中对压力检测部件14产生不同的压力。这样，可以通过压力检测部件14检测弹性连接部件13在折叠运动中对压力检测部件14所产生的压力值变化，进而能够基于检测到的压力值确定折叠结构10对应的折叠角度，不仅使折叠结构10具备简单的结构，且易于检测。
可选地，如图4所示，压力检测部件14设置于第一壳体11，且压力检测部件14包括压力传感器141、弹簧142、滑块143和滑槽144，压力传感器141、弹簧142和滑块143均位于滑槽144中；
弹簧142的第一端固定在滑槽144的一端，弹簧142的第二端与压力传感器141连接，压力传感器141还与滑块143连接，滑块143还与弹性连接部件13的第一端131连接，滑块143可沿滑槽144滑动。
即一种具体的实施方式中，如图4所示，压力检测部件14可包括压力传感器141、弹簧142、滑块143和滑槽144，其中，滑槽144设置在第一壳体11中，用作滑块143的滑动通道，压力传感器141、弹簧142和滑块143则均设置于滑槽144中，其中弹簧142可以位于滑槽144中靠近第二壳体12的一侧，压力传感器141和滑块143则位于滑槽144中远离第二壳体12的另一侧，也可以是弹簧142位于滑槽144中远离第二壳体12的一侧，压力传感器 141和滑块143则位于滑槽144中靠近第二壳体12的另一侧。
具体地，弹簧142的第一端固定在滑槽144的一端，如可以是滑槽144的靠近第二壳体12的一端，也可以是滑槽144的远离第二壳体12的另一端，弹簧142的第二端则与压力传感器141连接，如可以紧挨压力传感器141，以保证压力传感器141所受的压力大小等于弹簧142的反弹力，压力传感器141还与滑块143连接，如可以固定于滑块143的一侧，滑块143还与弹性连接部件13的第一端131连接。这样，在折叠结构10的折叠运动过程中，第二壳体12可通过弹性连接部件13的固定第二端132带动弹性连接部件13的其他部分运动，进而可带动滑块143、压力传感器141在滑槽144中运动，弹簧142则在滑块143和压力传感器141的运动下被压缩或被拉伸，弹簧142的压缩反弹力也发生相应变化，基于此运动原理，可以推算出折叠结构10的折叠角度与压力传感器141检测到的压力值之间的转换关系。
通过该实施方式，既可以保证折叠结构10易于折叠的效果，降低折叠结构复杂度，又能保证基于该结构能够较为准确地检测出折叠过程中的压力值变化，进而准确确定折叠结构10的折叠角度。
可选地，弹簧142的第一端固定在滑槽144中靠近第二壳体12的一端。
即一种实施方式中，弹簧142的第一端可以固定在滑槽144中靠近第二壳体12的一端，也就是说，可以如图4所示，弹簧142位于靠近第二壳体12和弹性连接部件13的一侧，当第一壳体11为左侧壳体时，弹簧142位于滑槽144的右侧，且一端固定在滑槽144的右端，压力传感器141和滑块143位于滑槽144的左侧，且弹簧142的另一自由端与压力传感器141连接，滑块143还与弹性连接部件13的末端连接。
这样，当折叠结构10完全展开时，弹簧142可以处于一定的压缩状态，或者处于自然状态，此时弹簧142的初始长度为X 0，压力传感器141检测到的初始压力值为F 0。
当折叠结构10开始折叠时，第二壳体12可通过弹性连接部件13的固定点也即第二端132，带动弹性连接部件13的其他部分向第二壳体12移动， 与弹性连接部件13的末端也即第一端131相连的滑块143也会伴随着向第二壳体12所在方向移动，如图5和图6所示，此时弹簧142在滑块143的移动下被不断压缩，弹簧142的压缩反弹力逐渐增大，压力传感器141检测到的压力值也会逐渐增大，当折叠结构10完全折叠时，弹簧142最短为X m，弹簧142反弹力最大为F m，压力传感器141检测到的压力值也为F m。
通过该实施方式，可保证在折叠结构10折叠程度越大时，相应的弹簧压缩量和反弹力也越大，压力传感器141检测到的压力值也越高，且弹簧反弹力与对压力传感器141的压力值是相等的，进而能够保证基于此原理较为准确容易地检测出折叠结构的折叠角度。
可选地，压力传感器141为压阻式压力传感器。
即一种实施方式中，可以选择压阻式压力传感器作为本申请实施例中的压力检测器件，其中，压阻式压力传感器是利用单晶硅的压阻效应和微电子技术制成，是一种新的物性型传感器。该实施方式中，采用的压阻式压力传感器，具有灵敏度更高、动态响应好、精度高、技术成熟度高、稳定性好、成本低等优点，且易于微型化和集成化，较适用于弹性连接结构且体积不大的折叠结构中。
可选地，弹性连接部件13为铰链式结构。
即一种实施方式中，弹性连接部件13可以采用铰链式结构，以保证折叠结构10结构简单稳定、折叠性能好，进而提高用户使用体验，应用前景也更为广泛。
需说明的是，对于上述铰链式折叠结构，除了机身内部的铰链啮合结构来保证屏幕在弯曲时不被拉伸损坏之外，还可以在折叠结构上下两端分别设置所述铰链式结构的弹性连接部件和压力检测部件，以增强整体结构的稳定性。
本申请实施例中的折叠结构包括：第一壳体、第二壳体、弹性连接部件和压力检测部件，其中，所述第一壳体和所述第二壳体通过所述弹性连接部件连接，且所述第一壳体可相对所述第二壳体转动；所述压力检测部件与所 述弹性连接部件连接，用于检测所述弹性连接部件的压力值。这样，由于采用的是弹性连接部件和压力检测部件来实现，从而相比现有转轴式折叠结构，整机厚度会相对较薄一些，且转动角度和转动幅度不会受到转轴的限制，能够获得更好的折叠效果。
本申请实施例还提供一种电子设备，包括图1至图6中实施例所提供的折叠结构。本实施例中，所述电子设备能达到和图1至图6所示实施例相同的有益效果，为避免重复，这里不再赘述。
请参见图7，图7为本申请实施例提供的折叠角度确定方法的流程图，应用于前述实施例中所述的折叠结构，如图7所示，所述方法包括：
步骤701、获取所述折叠结构的压力检测部件检测到的第一压力值。
步骤702、根据所述第一压力值，确定所述折叠结构的折叠角度。
在前述实施例中所介绍的折叠结构的基础上，可以采用本实施例中的折叠角度确定方法来确定折叠结构的折叠角度。
其中，上述获取所述折叠结构的压力检测部件检测到的第一压力值，可以是读取所述压力检测部件当前的压力值读数，得到所述第一压力值。
上述根据所述第一压力值，确定所述折叠结构的折叠角度，可以是基于预先确定的压力值与折叠角度的对应关系，确定所述第一压力值对应的折叠角度，从而得到所述折叠结构的折叠角度，或者，基于预先确定的压力与折叠角的转换计算公式，对所述第一压力值进行转换计算，进而得到所述折叠结构的折叠角度。
具体地，在所述压力检测部件包括压力传感器、弹簧、滑块和滑槽时，可以基于弹簧力学原理和圆心角、折叠角与弹簧压缩长度之间的关系，预先确定压力与折叠角的转换关系，如确定压力与折叠角之间的转换计算公式，或建立各压力值与折叠角度的一一对应关系。从而在需要确定折叠结构的折叠角度时，可以获取所述折叠结构的压力检测部件当前所检测到的第一压力值，再基于预先确定的所述转换关系，对所述第一压力值进行转换，得到转换后的折叠角度，也即所述折叠结构当前的折叠角度。
其中，如图4所示，所述压力检测部件包括压力传感器、弹簧、滑块和滑槽时，可以通过如下方式确定压力与折叠角之间的转换计算公式：
基于弧长、半径和圆心角之间的数学关系，建立所述折叠结构的弹簧的变化长度与所述折叠结构的旋转半径和折叠变化角度之间的第一计算公式；
基于所述弹簧的弹力计算公式和所述第一计算公式，确定压力与折叠角之间的第二计算公式；
基于所述第二计算公式，以及所述折叠结构在特定状态时的折叠角度和压力值，对所述第二计算公式进行转换，得到转换计算公式，其中，所述特定状态包括完全展开状态或完全折叠状态，所述完全展开状态下的折叠角度为180度，所述完全折叠状态下的折叠角度为0度。
具体地，所述压力传感器的反馈值F(也即检测到的压力值)与弹簧长度X的关系如图8所示，可使用公式F＝K·ΔX表示，其中，ΔX＝X-X 0，K为弹簧弹性系数，ΔX为弹簧压缩量，X 0为弹簧未折叠也即未受力时的长度。
折叠角与弹簧压缩长度之间的数学模型可如图9所示，其中，A1和A2分别表示折叠前和折叠后的折叠角度，a1和a2则分别表示折叠前和折叠后的圆心角，R表示旋转半径，R由折叠结构实际结构决定，根据图9可知，Δa＝a2-a1，使用圆心角从a1过渡至a2时的弧长变化来表示弹簧长度变化，从而根据弧长与圆心角之间的数学关系可得，ΔX＝R·Δa＝R(a2-a1)，而圆心角与折叠角的关系为A＝π-a，因此可进一步得到，ΔX＝R(a2-a1)＝R((π-A2)-(π-A1))＝R(A1-A2)。
综合以上公式F＝K·ΔX和ΔX＝R(A1-A2)，可以得出压力和折叠角的数学关系为：F＝K·ΔX＝KR(A1-A2)。
由于在实际使用过程中，对于折叠结构而言，压力值F已知，而折叠角度未知，故可以对上式进行转化。具体可以是，定义折叠结构完全展开时，折叠角度为180°，即为π，完全折叠时折叠角度为0°，则可以将上式转化为：F-F 0＝K·ΔX＝KR(π-A)，或者F-F m＝K·ΔX＝KR(0-A)，进而可得A＝π-(F-F 0)/KR，或者，A＝(F m-F)/KR。
也就是说，一种实施方式中，所述压力检测部件包括压力传感器、弹簧、滑块和滑槽；
所述步骤702包括：
基于预先确定的压力与折叠角的转换计算公式，对所述第一压力值进行转换计算，得到所述折叠结构的折叠角度；
其中，所述转换计算公式可以表示为A＝π-(F-F 0)/KR，或A＝(F m-F)/KR，其中，A表示折叠角度，F表示第一压力值，F 0表示完全展开状态时的压力值，F m表示完全折叠状态时的压力值，K表示所述弹簧的弹性系数，R表示所述折叠结构的旋转半径。
这样，折叠角A与压力传感器的反馈值F的关系可以如图10所示。
该实施方式中，可以基于上述转换公式A＝π-(F-F 0)/KR，或A＝(F m-F)/KR，将读取到的压力传感器的反馈值F也即第一压力值代入公式中进行计算，便可快速确定所述折叠结构的折叠角度，且由于该公式是基于弹簧力学原理和圆心角相关数学公式推导出来的，从而可保证基于该公式和当前压力值确定的折叠角度较为准确可信。
本实施例中的折叠角度确定方法，获取折叠结构的压力检测部件检测到的第一压力值；根据所述第一压力值，确定所述折叠结构的折叠角度。这样，通过该方式可快速准确地确定折叠结构的折叠角度。
需要说明的是，本申请实施例提供的折叠角度确定方法，执行主体可以为折叠角度确定装置，或者该折叠角度确定装置中的用于执行折叠角度确定方法的控制模块。本申请实施例中以折叠角度确定装置执行折叠角度确定方法为例，说明本申请实施例提供的折叠角度确定装置。

获取模块1101，用于获取所述折叠结构的压力检测部件检测到的第一压力值；
确定模块1102，用于根据所述第一压力值，确定所述折叠结构的折叠角度。
可选地，所述压力检测部件包括压力传感器、弹簧、滑块和滑槽；
确定模块1102用于基于预先确定的压力与折叠角的转换计算公式，对所述第一压力值进行转换计算，得到所述折叠结构的折叠角度；
其中，所述转换计算公式为A＝π-(F-F 0)/KR，或A＝(F m-F)/KR，其中，A表示折叠角度，F表示第一压力值，F 0表示完全展开状态时的压力值，F m表示完全折叠状态时的压力值，K表示所述弹簧的弹性系数，R表示所述折叠结构的旋转半径。
本实施例中的折叠角度确定装置，获取折叠结构的压力检测部件检测到的第一压力值；根据所述第一压力值，确定所述折叠结构的折叠角度。这样，折叠角度确定装置可快速准确地确定折叠结构的折叠角度。
