具体实施方式
体现本公开特征与优点的典型实施例将在以下的说明中详细叙述。应理解的是本公开能够在不同的实施例上具有各种的变化，其皆不脱离本公开的范围，且其中的说明及附图在本质上是作说明之用，而非用以限制本公开。
在对本公开的不同示例性实施方式的下面描述中，参照附图进行，所述附图形成本公开的一部分，并且其中以示例方式显示了可实现本公开的多个方面的不同示例性结构、系统和步骤。应理解，可以使用部件、结构、示例性装置、系统和步骤的其他特定方案，并且可在不偏离本公开范围的情况下进行结构和功能性修改。而且，虽然本说明书中可使用术语“之间”、“侧”等来描述本公开的不同示例性特征和元件，但是这些术语用于本文中仅出于方便，例如根据附图中所述的示例的方向。本说明书中的任何内容都不应理解为需要结构的特定三维方向才落入本公开的范围内。
参阅图1，图1中代表性地示出了能够体现本公开的原理的虚拟成像显示装置于收折状态的立体结构示意图。在该示例性实施方式中，本公开提出的虚拟成像显示装置是以适配一平板电脑为例进行说明的。本领域技术人员容易理解的是，为将该虚拟成像显示装置应用于或适配于其他类型的显示装置或电子装置等，而对下述的具体实施方式做出多种改型、添加、替代、删除或其他变化，这些变化仍在本公开提出的虚拟成像显示装置的原理的范围内。
如图1所示，在本实施方式中，本公开提出的虚拟成像显示装置主要包括底板10、面板20、镜头安装板30、投射镜头40以及三块半透镜50。配合参阅图2至图7 所示，图2代表性地示出了该虚拟成像显示装置于打开状态下的立体结构示意图；图3代表性地示出了该虚拟成像显示装置的底板10的立体结构示意图；图4代表性地示出了该虚拟成像显示装置的面板20的立体结构示意图；图5代表性地示出了该虚拟成像显示装置的镜头安装板30的立体结构示意图；图6代表性地示出了该虚拟成像显示装置于收折状态下的各半透镜50与底板10的立体组合示意图；图7代表性地示出了该虚拟成像显示装置的半透镜50的局部剖视图。以下结合上述附图，对本公开提出的虚拟成像显示装置的各主要结构和功能进行详细说明。
如图1至图4所示，在本实施方式中，面板20可转动地设于底板10的其中一侧边。为将面板20可转动地设置于底板10，可在底板10的连接有面板20的该侧边上设置第一枢转结构，该第一枢转结构可以例如为转轴或其他结构。进一步地，底板10的连接有面板20的该侧边上设有第一限位装置，例如限位块13或其他限位结构，以在面板20翻转至与底板10垂直或其他设定角度时，利用限位块13的阻挡限制面板20继续向远离底板10的方向翻转，即限制面板20朝向底板10的打开角度。
另外，在本实施方式中，基于该虚拟成像显示装置适配为一平板电脑的设计，上述面板20可作为一触控面板20，且底板10内设有电连接于触控面板20的电源装置，以通过电源装置向触控面板20供电。再者，该电源装置亦可向投射镜头40或其他用电元件供电，或采用额外的供电装置，上述实施方式并不限制本公开其他用电元件的供电配置方案。在本实施方式中，电源装置至少包括太阳能电池板，以使虚拟成像显示装置处于有外界光源的环境中能够吸收储存电能，并在无法充电或光照不足的环境中，利用太阳能电池板放电，保证设备的持续使用。基于上述设计，可以实现平板电脑与虚拟成像显示装置的折叠转换，进一步实现无法充电时设备使用的应急需求。
如图2和图5所示，在本实施方式中，镜头安装板30可转动地设于面板20朝向底板10的一侧面，以触控面板20为例，镜头安装板30的该侧面即为相反于触控面的另一侧面。其中，面板20的该侧面上开设有第一凹槽21，以供镜头安装板30在收折状态时容置在第一凹槽21中，不至凸出于面板20的朝向底板10的侧面。进一步地，考虑到某些类型的投射镜头40的尺寸，其在安装于镜头安装板30时，是凸出于镜头安装板30的朝向面板20的侧面，因此可在第一凹槽21的槽底开设第二凹槽22，以供镜头安装板30在收折状态时，投射镜头40部分容置于第二凹槽22中，不至阻碍镜头安装板30与第一凹槽21的槽底的贴合。
如图2和图5所示，在本实施方式中，投射镜头40可以可拆卸的方式安装在镜 头安装板30上。对于不同的虚拟成像功能的需求，可灵活选择多种类型的投射镜头40，并将上述第二凹槽22的尺寸设计为满足最大尺寸的一种备用的投射镜头40为宜，但并不以此为限。
如图2、图3和图6所示，在本实施方式中，三块半透镜50分别可转动地设于底板10的除连接面板20的侧边以外的其他三侧边。为将各半透镜50可转动地设置于底板10，可在底板10的连接有三块半透镜50的三侧边上分别设置第二枢转结构，该第二枢转结构可以例如为转轴或其他结构。具体而言，在本实施方式中，配合参阅图8，图8示出了一块半透镜50通过该第二枢转结构可转动地连接于底板10的局部放大图。如图8所示，该第二枢转结构可至少包括一根转轴51，且半透镜50临近底板10的一侧边开设有供转轴51穿设的轴孔，转轴51伸出于轴孔的两端部分别连接于底板10的连接结构，且该连接结构可以为类似轴座的凸起结构14，并不以此为限。其中，利用转轴51而实现相对枢转的设计，可以是转轴51与半透镜50相对固定，而使两者整体相对枢接于底板10，亦可是转轴51与底板10相对固定，而使半透镜50相对于转轴51枢转。
进一步地，底板10的连接有半透镜50的各侧边上亦可分别设置第二限位装置(未图示)，以在各半透镜50翻转至特定角度时，限制各半透镜50继续向远离底板10的方向翻转，即限制半透镜50相对于底板10的打开角度。具体而言，该第二限位装置可以为近似于限位块13的另一限位块结构，但在设计中需避免影响收折状态下底板10与面板20的贴合收折。再者，该第二限位装置亦可以其他结构形式设置，且可灵活调整设置位置，例如设置在转轴51或半透镜50的轴孔处，直接限制转轴51相对轴孔或底板10的转动角度，均不以此为限。
如图2、图3和图6所示，在本实施方式中，底板10上开设有第三凹槽11，以供各半透镜50在收折状态时容置于第三凹槽11，不至凸出于底板10的朝向面板20的侧面。另外，如底板10仅设置第三凹槽11，则基于各半透镜50的尺寸和形状，半透镜50在第三凹槽11中可能出现部分重叠的情况，或互不干涉的情况。对此，可综合考虑各半透镜50的形状、尺寸和厚度等条件，确定第三凹槽11的槽深，以确保收折状态时不影响面板20与底板10的贴合。
进一步地，如图3和图6所示，在本实施方式中，第三凹槽11的槽底开设有第四凹槽12，以三块半透镜50的其中至少一块在收折状态时容置于第四凹槽12。具体而言，虚拟成像显示装置处于收折状态时，由于部分半透镜50可能产生重叠，则利 用第四凹槽12的设计，使其中位于上层的部分半透镜50容置于第三凹槽11，位于下层的部分半透镜50容置于第四凹槽12。结合本实施方式的具体情况，是将于面板20相对位置的一块半透镜50设计为容置在第四凹槽12中，其余的相对于面板20两侧的两块半透镜50是容置在第三凹槽11中，即叠置于上述一块半透镜50的上层。在其他实施方式中，基于第四凹槽12的设计，半透镜50的容置方案和叠置次序均可灵活调整，并不以本实施方式为限。
另外，在本实施方式中，基于第二枢转结构的设计，各第二枢转结构(例如转轴51与底板10的类似轴座的凸起结构14)均凸出于底板10的朝向面板20的侧面，亦相当于在该侧面形成凹槽结构，虚拟成像显示装置处于收折状态时，各半透镜50容置于凹槽结构中。在本实施方式中，该凹槽结构即为上述的第三凹槽11。
另外，在本实施方式中，每块半透镜50可包括基板以及半透反射膜，半透反射膜分别贴附于基板的两个侧面。进一步地，半透镜50的材质可以例如为聚甲基丙烯酸甲酯(即有机玻璃，英文缩写为PMMA)，但并不以此为限。
承上所述，通过面板20、镜头安装板30和各半透镜50的翻转，虚拟成像显示装置能够在收折状态和打开状态之间转换。当虚拟成像显示装置处于收折状态时，镜头安装板30贴合于面板20，即容置于第一凹槽21内，投射镜头40则容置于第二凹槽22内。各半透镜50贴合于底板10，即分别容置于第三凹槽11或第四凹槽12内。并且，面板20和镜头安装板30共同贴合于底板10和各半透镜50。当虚拟成像显示装置处于打开状态时，面板20大致垂直于底板10，镜头安装板30大致垂直于面板20，各半透镜50相对底板10向上翻转，使镜头安装板30及各半透镜50相互对接而共同界定一锥台结构，以将镜头安装板30支撑起来，同时供投射镜头40在该锥台结构内实现虚拟成像的功能。
另外，需要说明的是，本实施方式中是以平板电脑常用的形状之一，即长方形，对本公开进行描述。然而本领域技术人员容易理解的是，虚拟成像显示装置可采用其他多种形状，即底板10的形状、面板20的形状、半透镜50的数量和形状均可根据虚拟成像旋转装置的形状灵活调整，并不以本实施方式为限。
在此应注意，附图中示出而且在本说明书中描述的虚拟成像显示装置仅仅是能够采用本发明原理的许多种虚拟成像显示装置中的一个示例。应当清楚地理解，本发明的原理绝非仅限于附图中示出或本说明书中描述的虚拟成像显示装置的任何细节或虚拟成像显示装置的任何部件。
举例来说，如图5所示，在本实施方式中，镜头安装板30的与各半透镜50对接的各侧边分别呈斜面结构31，各半透镜50的与镜头安装板30对接的各侧边分别呈另一斜面结构31，镜头安装板30与半透镜50对接时，相对应的斜面结构31相互贴合。基于上述设计，能避免上述结构对接时，对接处发生干涉而影响对接效果的情况发生。类似地，各半透镜50的与相邻半透镜50对接的侧边分别呈斜面结构31，相邻的半透镜50对接时，相对应的斜面结构31相互贴合。
又如，如图7所示，在本实施方式中，镜头安装板30的与各半透镜50对接的各侧边(即为上述的斜面结构31)上分别设有多个微型磁铁32，各半透镜50的与镜头安装板30对接的各侧边(即为上述的另一斜面结构31)上分别设有多个微型磁铁32，镜头安装板30与各半透镜50通过相对应的微型磁铁32磁吸对接。基于上述设计，能够进一步保证上述结构对接时的对接稳定度。类似地，各半透镜50的与相邻半透镜50对接的侧边(即为上述的斜面结构31)上分别设有多个微型磁铁32，相邻的半透镜50通过相对应的微型磁铁32磁吸对接。
再如，基于虚拟成像显示装置适配为一平板电脑的实施方式，虚拟成像显示装置还可包括控制器。该控制器可设置在底板10或面板20，以控制投射镜头40的虚拟影像60。进一步地，虚拟成像显示装置还可包括无线信号连接装置。该无线信号连接装置可设置在底板10或面板20，以接收无线信号，并反馈至投射镜头40的虚拟影像60，从而实现虚拟成像显示装置的远程无线连接和远程无线控制功能。
本公开提出一种虚拟成像显示装置，通过对面板、镜头安装板和半透镜等结构进行合理的结构设计，使得各块半透镜和投影镜头可以方便的折叠收纳，减小装置的体积，使装置在收折状态下容易携带。且通过替换不同类型的投射镜头，使装置的成像方式和功能得到扩展。
