请一并参考图2，该头戴式显示装置100还包括连接于本体20且用于将头戴式显示装置100穿戴至佩戴者头部的头带30、耳机40、设置于本体20的扬声器42、以及处理器50。处理器50电连接于耳机40、两个显示模块10和扬声器42，用于信号处理。处理器50在本实施例中装配于头戴式显示装置100中，例如，设置于本体20中。可以理解的，在其它实施方式中，处理器50和/或电源等功能模块可为分离式的独立设备，并通过插拔式接口连接至头戴式显示装置100。其中，扬声器42也可设置于头戴式显示装置100的任意位置，例如可设置于头带30、或耳机40。
请一并参考图3、图4和图6，该两个显示模块10转动设置于本体20。每一个显示模块10可以为包括显示器102及光学模组104的一体结构，也可以为独立于光学模组104的单一显示器102结构。光学模组104为特殊光学透镜，用于将相应显示面101提供的光源按照预设的光路投射出放大的虚像，以使小尺寸的屏幕能够投射出大屏幕的显示效果。具体的，显示模块10显示面101提供的光源经光学模组104后，穿过观看视窗投射至佩戴者双眼。可以理解的是，图示仅为原理示意图，并不用于限定本发明各模块的具体位置。其他实施方式中，可以根据需求灵活选择观看外侧，可转动的显示模块10设置于该观看外侧的对应区域即可。例如显示模块10可以置于本体20的欲分享至对外相对两侧端，如图5所示，当欲通过本体侧面进行对外分享时，该模式下显示面101可通过侧端转动至对外。且在对内显示模式下，显示面101可以转动至正对观看内侧20A对应的一个观看视窗21，也可以转动至其他方向，只要该模式下，显示面101朝向光学模组104的入光侧，通过该光学模组104设计的光路形成通过观看内侧20A对应的观看视窗21出射光束即可。根据本发明上述原理，显示器10可置于本体任意位置。
具体的，一体结构可以为任意可相对固定显示器102及其对应光学模组104，且具有可使光束出射的结构，例如显示模块10可以包括固定显示器及光学模组的封闭的盒体，该盒体对应显示面101光源形成的出射光束的位置设置有光束出射的观看视窗；显示模块10也可以包括固定显示器102及光学模组104同时不遮蔽显示面101的固定基座等。该方式下，光学模组104可以与显示器102一同转动。在本实施例中，该两个显示模块10大致呈矩形。可以理解，在其它实施方式，该两个显示模块10还可以是椭圆形、正多边形等。每一个显示模块10相对两侧边(例如，上侧边和下侧边)均设置有转轴150。两转轴150共轴线A设置。轴线A在本实施例中分别为显示模块10的对称轴。转轴150还开设有通孔152，以允许连接显示模块10的信号线穿过。在本实施例中，通孔152沿轴线A方向延伸，并在转轴150远离显示模块10的末端形成开口。在其它实施例中，转轴150还可设置于显示模块10另外相对两侧边(例如，左侧边和右侧边)，二者共轴的轴线与本实施方式中的轴线A垂直。
本体20的结构可以为类似于普通眼镜的镜框，也可以为一具有内部容置空间的盒体，结合图5所示，该盒体的观看内侧20A，即对应用户双眼的一侧，设有可投射出光束的观看视窗21，供佩戴者观看。本体20还包括观看外侧20B。本体20的观看外侧20B还开设有对外显示模式下提供显示模块10光源出射的开口210。该开口210的形状与显示模块10的形状相适配。具体的，当该本体20为上述盒体结构时，开口210设置于观看外侧20B，即非观看内侧20A所在侧，例如，可以为观看视窗21所在侧的对侧、左侧、右侧、上侧、底侧。结合图1至图4提供的示例中，本体20设有两个大致呈矩形的开口210。该两个开口210分别用于安装两个显示模块10。每一个开口210的上侧壁211和下侧壁212均开设有用于收容转轴150的轴孔214。转轴150转动收容于轴孔214，以使显示模块10能够相对本体20转动，从而使显示模块10的显示面101能够从朝向通过观看内侧20A出射光源的方向的对内显示模式切换至通过开口210朝向佩戴者以外的其他人的对外显示模式，以允许佩戴者能够与 其他人实现显示内容的分享。开口210相对该两个轴孔214的连线呈轴对称。轴孔214的内壁开设有与通孔152对应的穿孔(未示出)，以允许连接显示模块10的信号线通过轴孔214、通孔152走线至本体20内部，实现与该穿戴式显示装置100其他模块的电连接，包括电连接至处理器50。该方式下可以充分利用内部空间，实现走线隐藏于穿戴式显示装置的内部。
在本实施例中，该头戴式显示装置100默认的声音显示模式为声音内放，即通过耳机40播放。当显示模块10切换至对外显示模式时，自动启动声音外放，即启动扬声器42播放。具体的，该头戴式显示装置100还包括两个转动传感器60。该两个转动传感器60电连接于处理器50，用于检测显示模块10的状态并当检测到任意显示模块10切换至对外显示模式时产生检测信号。处理器50用于当接收到检测信号时启动声音外放模式，即控制音频信号通过扬声器42播出。如此，佩戴者能够与其他人实现音频及显示内容同步分享，提高用户体验。可以理解的是，当接收到检测信号时，启动声音外放包括耳机40与扬声器42同时播放，也包括直接切换扬声器42播放，此时耳机40停止播放。该对应的播放选择模式，可以灵活设置，较优的可以提供至用户进行自配置选择。
结合图4的实施例，该头戴式显示装置100还包括锁扣组件70。该例中包括两个锁扣组件70分别设置于两个显示模块10上，用于当显示模块10处于对内显示模式或对外显示模式时锁定显示模块10。锁扣组件70包括活动设置于显示模块10上的锁扣件72、抵接于锁扣件72以使锁扣件72伸出于显示模块10的弹性件(未示出)、以及用于驱动锁扣件72缩回显示模块10的按钮74。开口210相对的两个侧壁均开设有用于卡合锁扣件72的卡合凹槽216。锁扣件72配合卡合凹槽216锁定显示模块10。具体的，当显示模块10处于对内显示模式时，锁扣件72卡合至左侧壁的卡合凹槽216以锁定显示模块10，从而保持对内显示模式不变。当需要切换至对外显示模式时，按压按钮74，锁扣件72与左侧壁的卡合凹槽216分离并缩回显示模块10中，具体的，可以为按压按钮74，带动弹簧件驱动锁扣件72缩回显示模块10，此时，将显示模 块10旋转180度，锁扣件72卡合至右侧壁的卡合凹槽216以将显示模块10锁定并保持在对外显示模式。
可以理解的，在其它实施方式中，所述锁扣组件70设置于本体20上，所所述显示模块10相对两侧开设有卡合凹槽216。卡合凹槽216与锁扣件72配合锁定显示模块10以使显示模块10保持在对外显示模式或对内显示模式。
其他实施方式中，锁扣组件可以为任意可锁固的结构，例如限位结构、卡扣结构、磁性吸合结构等。
在一实施例中，显示模块10的边缘的正反两面均设置有操作组件801。当佩戴者转动显示模块10时，通过扣动操作组件801以使显示模块10翘起，便于顺利转动显示模块10。
组装时，将转轴150转动收容于轴孔214中，并使信号线穿过通孔152、穿孔后电连接至处理器50，从而将显示模块10安装至本体10。
如图6所示，使用时，若佩戴者不需要与他人共享显示内容，可将显示模块10切换至对内显示模式，此时，显示模块10的显示面101分别朝向佩戴者左右眼睛。如图7所示，当佩戴者需要与他人共享视频时，转动其中一个或两个显示模块10以使该显示模块10切换至对外显示模式，此时，该显示模块10的显示面101转向观看外侧20B，以使其他人能看到显示内容。与此同时，转动传感器60产生检测信号，处理器50控制音频信号通过扬声器42以外放的形式播出。如此，佩戴者能够与其他人实现音频及显示内容同步分享，提高用户体验。
如图8所示，在本发明另一实施例中，显示模块10为独立于光学模组104的单一显示器102结构，并对应光学模组104设置。显示模块10基于上述转动结构转动设置于本体20实现对内显示模式与对外显示模式的切换。本体20还设置有会聚透镜106。会聚透镜106与显示模块10相对应，用于当显示模块10的显示面101朝向观看外侧20B(此时为对外显示模式)时，将显示模块10显示内容放大以便于他人观看。会聚透镜106和光学模组104设置于显示模块10的相对两侧。具体的，会聚透镜106设置于本体20开设有开口210 的一侧。优选地，会聚透镜106在本实施方式中为菲涅尔透镜。会聚透镜106在其它实施方式中也可以为可将图像放大的光学元件或镜头模组。在本方式中，可通过设置转动机构，例如通过固定连接至转轴150的转动旋钮来转动显示模块10。也可以通过设置驱动马达，该驱动马达可以电连接至处理器50，通过电控的形式来转动显示模块10。结合图5所示，观看内侧20A具有提供佩戴者观看的观看视窗21，开口210设置于本体20的两侧端，会聚透镜106对应开口210的形状并嵌于开口210处，显示模块10对应开口210区域设置于本体20内，显示模块10的上侧边设有一转轴150，且该转轴150由本体20内部连接至本体20外部的操作部件80(参图5)，具体的，操作部件为一转动旋钮，通过旋转该操作部件80可带动转轴150转动，从而可使显示模块10的显示面101可转向会聚透镜106，也可使显示面101转向通过观看内侧20A出射光源的方向，即显示面101的光源可通过观看内侧20A的观看视窗21投射至用户双眼。具体的，显示面101可以转向观看视窗21的方向使得显示面101直接投射出观看视窗21。转轴150于显示模块10的纵向设置，即Y轴方向，该方式下，还可以根据显示面101可转向的观看外侧的任意位置设置多个开口210，例如还可以设置开口于观看内侧20A相对的一侧。其他方式中，转轴150还可以于显示模块10的横向设置，即X轴方向，该方式下，显示面101还可以转向本体20的上侧及底侧，相应的，可以于上侧及底侧对应显示面101的区域设置开口210
如图9和图10所示，本发明其他实施方式中，头戴式显示装置可以仅包括一个显示模块，具体的可以为一个显示器10，当其屏幕足够大时，可以基于上述转动原理实现对内显示模式与对外显示模式的切换。也可采用光学模组放大成像的方式，该模式下，增设分光模组109，显示器10显示的光束通过分光模组109分离出两路光束，该两路光束通过对应的光学模组104从观看内侧20A射出并分别投射至佩戴者的双眼。同上述实施例的原理，显示模块10可以为独立于前述光学模组的一个显示器10，实现显示器10的转动，显示模块10也可以为包括显示器10及前述光学模组的一体结构，实现显示器10与 光学模组的一同转动。
根据上述实施例，显示模块10可以仅包括显示器，该显示器的显示面101转向通过观看内侧20A出射光源的方向包括显示面不正对观看内侧20A的观看视窗21的方式，只要显示面101朝向设定的光学模组104，光学模组104可以定义出所需的光路，将显示面101的光源投射至观看内侧20A出射的光束，通过观看视窗21投射至佩戴者的双眼。
以上所述是本发明的优选实施例，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
