进一步的，为了保证第一光纤14和第二光纤21之间的光信号传输的可靠性，镜腿部件和/或镜架部件的接触面处可以设置密封机构，使在镜腿完全展开时第一光纤14和第二光纤21被完全包被，避免光纤受外界环境影响；如本实施例中的镜腿部件还可以包括设置在镜腿部件的接触面的密封机构， 用于在镜腿部件处于完全展开状态时，遮挡外界的光信号；例如本实施例中的镜腿部件可以包括设置在镜腿部件的接触面的伸缩连接套，以在镜腿部件处于完全展开状态时，能够遮挡外界的光信号，并且能够遮挡外界的灰尘，避免第一光纤14和第二光纤21的光纤截面上的灰尘对光信号传输的影响。
具体的，本实施例中的第一供电模块15可以为镜腿部件中的供电模块，如头戴式显示设备的镜腿部件对镜架部件供电的情况下，第一供电模块15可以在处于完全展开状态时，利用镜腿部件中的电池或外部供电，对镜腿部件(如主板模块11、编解码模块12、第一光收发模块13)供电并且通过第一供电触点16对镜架部件(如图1中的第二供电模块27)供电；第一供电模块15可以在未处于完全展开状态时，利用镜腿部件中的电池或外部供电，对镜腿部件自身进行供电。头戴式显示设备的镜架部件对镜腿部件供电的情况下，第一供电模块15可以在处于完全展开状态时，利用镜架部件通过第一供电触点16的电能传输，对镜腿部件自身进行供电。
需要说明的是，本实施例中的第一供电触点16可以为镜腿部件中设置的电能传输的触点，如图2中的金属触点。第一供电触点16可以设置在镜腿部件的折叠面，使得镜腿部件处于完全展开状态时，第一供电触点16可以与镜架部件中的第二供电触点26接触连接，与第二供电触点26进行电能传输，即镜腿部件处于完全展开状态时，第一供电模块15可以通过其连接的第一供电触点16向镜架部件的第二供电触点26传输电能，或者通过其连接的第一供电触点16接收镜架部件的第二供电触点26传输的电能。
具体的，本实施例并不限定第一供电触点16的具体触点数量和触点类型，如图3所示，第一供电触点16可以包括两个触点(第一固定触点和第二固定触点)，使得镜腿部件处于完全展开状态时，镜腿部件中的两个第一供电触点16可以分别与镜架部件中相应的两个第二供电触点26(如图3中的第一弹性触点和第二弹性触点)接触连接，构成供电回路，用于完成镜腿部件与镜架部件之间的电能传输。镜腿部件的第一供电触点16和/或镜架部件的第二供电触点26可以设置为弹性触点，例如本实施例中的第一供电触点16可以具体为弹性触点；其中，第二供电触点26为接触面与镜架部件的折叠面平齐的固定触点时，若镜腿部件处于完全展开状态，则处于压缩状态的第一供电触点16与第二供电触点26接触连接，且第一供电触点16的接触面 (即用于与第二供电触点26接触的面)与镜腿部件的折叠面平齐；若镜腿部件未处于完全展开状态，则第一供电触点16的接触面高出镜腿部件的折叠面。本实施例对此不做任何限制。
本实施例中，本发明实施例采用光纤技术实现头戴式显示设备中的镜腿部件与镜架部件之间的数据传输，采用触点供电的方式实现镜腿部件与镜架部件之间的电能传输，避免了FPC或其他线材由于弯折造成的信号衰减，提高头戴式显示设备的可靠性及使用寿命，从而能够通过对触点供电的检测，确定头戴式显示设备的使用情况，实现头戴式显示设备的自动开关机，提升用户体验；并且镜腿部件和镜架部件能够在分体组装后，再组装到一起，使组装更加便利，提高产品生产良率。
基于上述镜腿部件的实施例，本发明实施例提供了一种头戴式显示设备的镜架部件，具体请参考图1，图1为本发明实施例所提供的一种头戴式显示设备的结构示意图；该镜架部件可以包括：第二光纤21、第二光收发模块2222、编解码控制模块23、显示器件24、数据采集器件25、第二供电触点26、第二供电模块27；
其中，第二光纤21的一端设置在镜架部件的折叠面，第一光纤14在头戴式显示设备的镜腿部件处于完全展开状态时，与镜腿部件中的第一光纤14接触连接，用于传输光信号；
第二光收发模块22，用于完成第二光纤21传输的光信号与第二电信号之间的转换；其中，第二电信号为第二光收发模块22与编解码控制模块23之间传输的电信号；
编解码控制模块23通过第二光收发模块22和第二光纤21连接到镜腿部件的主板模块11，编解码控制模块23用于完成显示器件24和数据采集器件25传输的数据与第二电信号之间的转换，实现显示器件24和数据采集器件25各自与主板模块11之间的数据传输；
第二供电触点26设置在镜架部件的折叠面，用于在镜腿部件处于完全展开状态时，与镜腿部件中的第一供电触点16接触连接；第二供电模块27用于对镜架部件供电或对镜腿部件和镜架部件供电。
可以理解的是，本实施例中的第二光收发模块22可以为镜架部件中的光 收发模块(如图2中的光收发机)。第二光收发模块22可以第二光纤21传输来的数据信号(即光信号)，将光信号转换为电信号(即第二电信号)，并送到编解码控制模块23；接收来自编解码控制模块23的电信号(即第二电信号)，将电信号转换为光信号，并通过第二光纤21发送到镜腿部件的第一光收发模块13。也就是说，第二光收发模块22可以完成第二光纤21传输的光信号与第二电信号之间的转换，从而使得显示器件24和数据采集器需要向镜腿部件的主板模块11发送的数据可以转换为光信号通过第二光纤21发送到镜腿部件，且主板模块11需要向显示器件24和数据采集器发送的数据对应的第一光纤14传输的光信号可以依次通过第二光收发模块22和编解码控制模块23转换为相应的数据并发送到显示器件24和数据采集器。
具体的，本实施例中的第二光纤21可以为镜架部件中设置的光纤线路，第二光纤21的一端设置在镜架部件的折叠面，即镜架部件完全展开时与镜腿部件接触的一面；第二光纤21的另一端可以与第二光收发模块22连接。如图4和图5所示，镜架部件的折叠面上第二光纤21的一端的光纤截面(即第二光纤21截面)可以与镜架部件的折叠面平齐，镜腿部件的折叠面上第一光纤14的一端的光纤截面(即第一光纤14截面)可以与镜腿部件的折叠面平齐，使得镜腿部件处于完全展开状态时，第一光纤14的第一光纤14截面可以与第二光纤21的第二光纤21截面完全接触，完成光信号的传输。
进一步的，为了保证第一光纤14和第二光纤21之间的光信号传输的可靠性，本实施例中的镜架部件还可以包括设置在镜架部件的接触面的密封机构，用于在镜腿部件处于完全展开状态时，遮挡外界的光信号；例如本实施例中的镜腿部件可以包括设置在镜架部件的接触面的伸缩连接套，以在镜腿部件处于完全展开状态时，能够遮挡外界的光信号，并且能够遮挡外界的灰尘，避免第一光纤14和第二光纤21的光纤截面上的灰尘对光信号传输的影响。
相应的，本实施例中的编解码模块12可以与第二光收发模块22连接，用于接收来自第二光收发模块22的第二电信号形式传输的显示数据，并根据相应的解码规则进行解码，并将显示数据内容发送到显示器件24中；接收来自数据采集模块的数据，根据相应的编码规则进行编码，并将数据传输到第二光收发模块22中。也就是说，编解码控制模块23可以完成显示器件24和 数据采集器件25传输的数据与第二电信号之间的转换，实现显示器件24和数据采集器件25各自与主板模块11之间的数据传输。
具体的，本实施例中的显示器件24可以对接收的需要显示的数据进行显示的器件；本实施例中的数据采集器件25可以采集环境数据的器件。本实施例并不限定显示器件24和数据采集器件25的具体器件类型，如显示器件24可以包括OLED(有机发光二极管)屏和/或光波导显示器；数据采集器件25可以包括摄像头、环境光传感器、温湿度传感器、PPG(光电容积脉搏波描记法)传感器中的任意一项或多项。
对应的，本实施例中的第二供电模块27可以为镜架部件中的供电模块，如头戴式显示设备的镜腿部件对镜架部件供电的情况下，第二供电模块27可以在处于完全展开状态时，镜腿部件通过第二供电触点26的电能传输，对镜架部件(如第二光收发模块22、编解码控制模块23、显示器件24和数据采集器件25)进行供电。头戴式显示设备的镜架部件对镜腿部件供电的情况下，第二供电模块27可以利用镜架部件中的电池或外部供电，对镜架部件进行供电并且通过第二供电触点26对镜腿部件(如图1中的第一供电模块15)供电；第二供电模块27可以在未处于完全展开状态时，利用镜腿部件中的电池或外部供电，对镜架部件自身进行供电。
需要说明的是，本实施例中的第二供电触点26可以为镜架部件中设置的电能传输的触点，如图2中的金属触点。第二供电触点26可以设置在镜架部件的折叠面，使得镜腿部件处于完全展开状态时，第二供电触点26可以与镜腿部件中的第一供电触点16接触连接，与第一供电触点16进行电能传输。
具体的，本实施例并不限定第一供电触点16的具体触点数量和触点类型，如图3所示，第二供电触点26可以包括两个触点(第一弹性触点和第二弹性触点)，使得镜腿部件处于完全展开状态时，镜架部件中的两个第二供电触点26可以分别与镜腿部件中相应的两个第一供电触点16(如图3中的第一固定触点和第二固定触点)接触连接，构成供电回路，用于完成镜腿部件与镜架部件之间的电能传输。本实施例中的第二供电触点26可以具体为弹性触点；如图5所示，两个第一供电触点16(第一固定触点和第二固定触点)为接触面与镜架部件的折叠面平齐的固定触点，在镜腿部件处于完全展开状态时，处于压缩状态的两个第二供电触点26(第一弹性触点和第二弹性触点) 可以与相应的第一供电触点16接触连接，且两个第二供电触点26的接触面(即用于与第一供电触点16接触的面)与镜架部件的折叠面平齐；若镜腿部件未处于完全展开状态，则两个第二供电触点26的接触面高出镜腿部件的折叠面。本实施例对此不做任何限制。
本实施例中，本发明实施例采用光纤技术实现头戴式显示设备中的镜腿部件与镜架部件之间的数据传输，采用触点供电的方式实现镜腿部件与镜架部件之间的电能传输，避免了FPC或其他线材由于弯折造成的信号衰减，提高头戴式显示设备的可靠性及使用寿命，从而能够通过对触点供电的检测，确定头戴式显示设备的使用情况，实现头戴式显示设备的自动开关机，提升用户体验；并且镜腿部件和镜架部件能够在分体组装后，再组装到一起，使组装更加便利，提高产品生产良率。
基于上述实施例，本发明实施例还提供了一种头戴式显示设备，包括：镜架部件、第一镜腿部件、第二镜腿部件；其中，第一镜腿部件和第二镜腿部件均与镜架部件可折叠连接，本实施例中的镜架部件可以为如上述实施例所提供的头戴式显示设备的镜架部件，本实施例中的第一镜腿部件可以为如上述实施例所提供的头戴式显示设备的镜腿部件。
进一步的，本实施例中第一镜腿部件与镜架部件的可折叠连接处设置有弹性部件，使得第一镜腿部件展开但未受外力时，第一镜腿部件有一定的回弹，如图6所示，以使第一镜腿部件在展开且未受到外力时，无法处于完全展开状态，从而使得用户未佩戴使用头戴式显示设备时，第一镜腿部件中的第一光纤和第一供电触点可以不与镜架部件相应的第二光纤和第二供电触点接触连接，保证后续头戴式显示设备的自动开关机的准确性。具体的，本实施例所提供的头戴式显示设备可以具体为AR(增强现实，Augmented Reality)设备，如AR眼镜；也可以具体为如VR(Virtual Reality，虚拟现实)眼镜的其他头戴式显示设备，本实施例对此不做任何限制。
基于上述实施例，本发明实施例还提供了一种头戴式显示设备的控制方法，具体请参考图7，图7为本发明实施例所提供的一种头戴式显示设备的控制方法的流程图；该方法应用于如上述实施例所提供的头戴显示设备的镜 腿部件，可以包括：
步骤101：主板模块检测第一供电模块的供电状态。
其中，本步骤中第一供电模块的供电状态可以包括镜腿部件的第一供电模块与镜架部件之间的电能传输情况，本实施例中主板模块可以利用检测到的第一供电模块的供电状态，确定镜腿部件的折叠情况，即头戴显示设备的使用情况。
具体的，对于本步骤中的供电状态的具体内容，可以由设计人员根据实用场景和用户需求自行设置，如本实施例中头戴式显示设备的镜腿部件对镜架部件供电的情况下，第一供电模块用于对镜腿部件和头戴显示设备的镜架部件供电时，第一供电模块的供电状态可以为包括镜腿部件处于完全展开状态时的对镜架部件供电的状态和镜腿部件未处于完全展开状态时的未对镜架部件供电的状态；本实施例中头戴式显示设备的镜架部件对镜腿部件供电的情况下，第一供电模块用于对镜腿部件供电时，第一供电模块的供电状态可以为包括镜腿部件处于完全展开状态时的使用镜架供电的状态和镜腿部件未处于完全展开状态时的未使用镜架供电的状态。
对应的，对于本步骤中主板模块检测第一供电模块的供电状态的具体方式，可以由设计人员根据实用场景和用户需求自行设置，如主板模块可以按预设时间间隔检测第一供电模块的供电状态；例如头戴式显示设备的镜腿部件对镜架部件供电的情况下，如图8所示，关机状态的主板模块可以在检测到开机键的触发指令后，按预设时间间隔检测第一供电模块的供电状态，即是否通过弹片(即第一供电触点)为镜架部件供电；如图9所示，运行状态的主板模块可以按预设时间间隔检测第一供电模块的供电状态，从而在供电状态为未对镜架部件供电的状态时，进入休眠状态，本实施例对此不做任何限制。
步骤102：根据供电状态，控制头戴显示设备的工作状态；其中，工作状态包括关机状态、休眠状态和运行状态。
可以理解的是，本实施例中主板模块可以根据检测到第一供电模块的供电状态，控制头戴显示设备的工作状态，即主板模块的工作状态。本实施例中头戴显示设备的工作状态可以包括关机状态、休眠状态和运行状态。
具体的，对于本步骤中主板模块根据供电状态，控制头戴显示设备的工 作状态的具体方式，可以由设计人员根据使用场景和用户需求自行设置，如第一供电模块用于对镜腿部件和头戴显示设备的镜架部件供电时，本步骤中主板模块可以在供电状态为对镜架部件供电的状态时，控制工作状态处于运行状态；在供电状态为未对镜架部件供电的状态时，控制工作状态处于休眠状态，并在工作状态处于休眠状态的持续时间达到关机预设时间后，控制工作状态处于关机状态。
如图8所示的头戴显示设备(如AR眼镜)的开机工作过程，该过程模拟了头戴显示设备从拿起开机到佩戴完整过程：用户在开始佩戴头戴显示设备前，头戴显示设备为关机状态，镜腿部件折叠。此时用户按开机键，设备进入开机状态；完成开机后，检测镜腿部件是否通过第一供电触点为镜架部件供电；如果未供电，说明镜腿处于折叠状态，没有进行佩戴，设备进入休眠状态；当检测到第一供电触点处于供电状态时，说明镜腿部件完全展开，处于正常佩戴状态，设备正常运行，可以利用第一光收发模块和第二光收发模块进行数据的传输。在完成头戴显示设备的佩戴后，设备已经进入正常工作状态，避免了常规开机方式中完成佩戴后才运行开机过程，减少了等待时间，提高用户体验效果；同时可以减少开机后未进行佩戴，造成电池能量的浪费，提升设备的续航能力，提高用户体验。
如图9所示的头戴显示设备(如AR眼镜)的关机工作过程，当头戴显示设备从佩戴状态摘下时，镜腿部件可以部分折叠，处于图6所示情况，此时第一供电触点由接触连接状态变为断开状态，设备检测到第一供电触点未给镜架部件供电，可以进入休眠状态；设备计算处于休眠状态的时间，并与预设关机时间比较；当休眠时间达到预设关机时间，设备可以自动进入关机状态。头戴显示设备能够自动进入休眠状态，避免造成电池能量浪费，提高设备的续航能力；并且头戴显示设备能够自动关机，简化用户操作，提升用户体验。
本实施例中，本发明实施例通过根据第一供电模块的供电状态，控制头戴显示设备的工作状态，可以利用对第一供电触点供电情况的检测，确定头戴式显示设备的使用情况，实现头戴式显示设备的自动开关机，提升了用户体验。
基于上述实施例，本发明实施例还提供了一种头戴式显示设备的控制装置，具体请参考图10，图10为本发明实施例所提供的一种头戴式显示设备的控制装置的结构框图。该装置应用于如上述实施例所提供的头戴显示设备的镜腿部件，可以包括：
供电获取单元10，用于主板模块检测第一供电模块的供电状态；
供电控制单元20，用于根据供电状态，控制头戴显示设备的工作状态；其中，工作状态包括关机状态、休眠状态和运行状态。
可选的，第一供电模块用于对镜腿部件和头戴显示设备的镜架部件供电时，供电控制单元20可以包括：
第一控制子单元，用于若供电状态为对镜架部件供电的状态，则控制工作状态处于运行状态；
第二控制子单元，用于若供电状态为未对镜架部件供电的状态，则控制工作状态处于休眠状态，并在工作状态处于休眠状态的持续时间达到关机预设时间后，控制工作状态处于关机状态。
本实施例中，本发明实施例通过供电控制单元20根据第一供电模块的供电状态，控制头戴显示设备的工作状态，可以利用对第一供电触点供电情况的检测，确定头戴式显示设备的使用情况，实现头戴式显示设备的自动开关机，提升了用户体验。
相应于上面的方法实施例，本发明实施例还提供了一种计算机可读存储介质，下文描述的一种计算机可读存储介质与上文描述的一种头戴式显示设备的控制方法可相互对应参照。
一种计算机可读存储介质，该计算机可读存储介质上存储有计算机程序，计算机程序被处理器执行时实现上述方法实施例所提供的头戴式显示设备的控制方法的步骤。
该计算机可读存储介质具体可以为U盘、移动硬盘、只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟或者光盘等各种可存储程序代码的可读存储介质。
说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是 与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。对于实施例公开的装置、而言，由于其与实施例公开的方法相对应，所以描述的比较简单，相关之处参见方法部分说明即可。
