请参考图1，本公开提供一种立体显示装置，包括箱体10，箱体10的整体结构呈长方体。具体的，箱体10包括相对的底板(参考图4的附图标记103)和顶板120，相对的前板150和背板(参考图6的附图标记102)，和相对的两个侧板110。底板、顶板120、前板150、背板和两个侧板110共同围合形成腔室(参考图6的附图标记101)。变形例中，侧板110的数量不限于两个，例如，侧板110的数量为4个、6个、8个等多个，多个侧板110形成的整体形状呈折板状，前板150一侧的侧板110数量分别为2个、3个、4个，当然，侧板110的数量还可以有其他组合，在此不再赘述。箱体10呈规则的长方体，便于制造。
其他实施例中，箱体10的整体形状也可呈除长方体外的其他形状，例如，箱体10呈球体、椭球体、圆台等形状。箱体10的前板150透明，可不设顶板 120、底板、背板和侧板110的任意一个或多个，换而言之，顶板120、底板、背板和侧板110为一块整体的板，可与前板150圆滑过渡，形成完整统一的外形。此时，腔室101的形状与箱体10对应。此实施例的箱体10，结构富有变化，个性化强，具有丰富的展示效果。
箱体10的前板150包括透明部15和边框部19，边框部19围合在透明部15的四周，透明部15例如为玻璃、塑料等透明材质的材料。透明部15的形状呈矩形，且该矩形的尺寸略小于箱体10的前板150的尺寸。透明部15的矩形的长宽比可以与常见的视频尺寸对应，例如4：3、16：9、16：10等。透过透明部15可以看到箱体10内部的结构。变形例中，也可不设透明部15，而是将箱体10的前板150整体设置为透明，即透明部15和边框部19均为透明，两者可为一体式结构。本公开的目的是在箱体10内部设置独特的结构，以实现结构简单且显示效果好的立体显示方案。
请参考图2，一种实施例中，箱体10的底部可设多个万向轮12，万向轮12用于支撑并移动箱体10。万向轮12也可以变形设计为普通的单向轮。
箱体10上还可设摄像头16，摄像头16用于拍摄画面，并可在箱体10内部的结构中显示。摄像头16可设置在箱体10的前板150，位于透明部15上方的边框部19处。摄像头16例如为可见光摄像头或红外摄像头。摄像头16的数量可以为多个。当然，上述摄像头16也可以作为外接设备，单独设置，并与立体显示装置连接。
请参考图3，本公开的箱体10上还可设扬声器17，扬声器17用于播放音频。扬声器17的数量可为1个或多个，扬声器17的设置位置可为箱体10的前板150或侧板110。
此外，箱体10上还可设麦克风或麦克风接口，通过麦克风接收箱体10周围的音频信息，或者通过与麦克风接口外接的话筒接收箱体10周围的音频信息。麦克风或麦克风接口的设置位置可以与扬声器17的设置位置相邻而形成整体，也可单独设置。
请参考图4，箱体10内设有箱底11、主板60和底板103。箱底11为箱体10的结构基础，万向轮12与箱底11转动连接。底板103设置在箱底11背向万向轮12的一侧。箱底11与底板103之间具有容纳空间，主板60设置在该容纳空间内。主板60例如为印刷电路板(Printed Circuit Board，PCB)，PCB上设有 芯片。主板60用于为透明显示屏20提供播放源信号。
继续参考图1和图4，箱体10内还设有透明显示屏20，透明显示屏20正对前板150，即透明显示屏20的显示面朝向箱体10的前板150，透明显示屏20用于显示画面。主板60与透明显示屏20电连接，主板60上的芯片用于控制透明显示屏20的显示。透明显示屏20例如为拆除了背光模组的液晶显示屏。
请参考图6，一种实施例中，箱体10呈长方体，具有长方体的腔室101，透明显示屏20容置在腔室101。透明显示屏20包括相对的底端21和顶端22，底端21设置于箱体10的底板103，顶端22设置在箱体10的顶板120或侧板110。其他实施例中，当箱体10呈其他形状时，例如未设顶板120和底板103，而是顶板120、底板103、背板102和侧板110为整体的一块板时，腔室101也呈与箱体10对应的形状，透明显示屏20的底端21设置在腔室101的底部，顶端22设置在腔室101的顶部，透明显示屏20的形状与腔室101的形状对应，边缘可具有一定的弧度。
透明显示屏20与前板150之间可以具有间隔距离，透明显示屏20与前板150之间的间距能提升画面的纵深感。透明显示屏20与前板150也可以紧贴设置，可视角度更大。透明显示屏20一方面提供观察的视窗，另一方面也起到保护透明显示屏20的作用。
请参考图4和图6，箱体10内还设有光源，光源朝向透明显示屏20发光。光源可以为1个或多个，例如图4中示出了第一光源41、第二光源42和第三光源43，第一光源41和第二光源42相对设置在箱体10的两个侧板上，第三光源43设置在与底板103相对的顶板110上。其中，第一光源41、第二光源42和第三光源43可以仅设置1个或2个。
请参考图6，箱体10的背板102上也可设光源，背板102上设置的光源与前述第一光源41、第二光源42和第三光源43类似，并且，光源的整体数量可以为1个、2个、3个和4个的任意一种。光源具体可以为发光二极管(Light Emitting Diode，LED)。通过设置光源，能够为透明显示屏20提供背光，以实现显示。上述光源设置的形式采用面光源的形式，使得腔室101内呈均匀一致的光线环境。.
可选的光源设置方案为：由于背板102正对透明显示屏，因此，背板102设主光源，背板102的主光源为透明显示屏20提供主要的光线，第一光源41、 第二光源42和第三光源42为辅光源，用于提升透明显示屏20的亮度。
本公开的立体显示原理：人眼看到物体是否为立体的观感通常为物体本身的外形以及物体的光影效果，该光影效果例如为在物体不同区域的高光和暗光，光线照射在物体后在地面的投影(即倒影)。利用该原理，本公开的光源向透明显示屏20提供光线，透明显示屏20接收到主板60传输的立体视频或图片的信号后，透明显示屏20显示出该立体视频或图片的画面，并形成倒影，透过箱体10的前板150的透明部15能够看到透明显示屏20的画面以及画面的倒影，从而在人眼中观察到立体画面。
一种实施例中，该倒影通过应用程序的控制而形成在透明显示屏20上，即透明显示屏20显示立体视频或图片的画面及该画面的倒影，从而使得人眼中观察到立体画面。
另一种实施例中，请参考图4和图6，该倒影形成在底板103上，也即形成在腔室101的底部的壁面上。由于箱体10的腔室101内设置的透明显示屏20呈透明状，当透明显示屏20上显示画面时，画面为不透明状，光源的光线照射透明显示屏20上显示的画面后，在底板103上形成倒影，从而使得人眼中观察到立体画面。
因此，本公开通过设置箱体10及透明显示屏20和光源，光源提供光线，透明显示屏20显示立体画面并形成倒影，实现立体显示，结构简单，显示效果好。
一种实施例中，请参考图7，在一些应用场景中，透明显示屏20上显示的画面例如为虚拟人物的动画，人在箱体10前做出动作时，透明显示屏20上的虚拟人物会做出对应的动作，实现人机交互。其实现方法为：主板60上设置有处理器和收发器，处理器和收发器可以与芯片集成，也可以单独设置，例如，处理器为芯片，收发器为独立的器件。处理器用于通过收发器获取图像信息和/或声音信息，并基于图像信息和/或声音信息，调整透明显示屏上展示的画面，例如为虚拟人物的动画信息。
收发器获取图像信息可以通过箱体10上的摄像头16获取，也可以接收服务器或其他终端设备发送的图像信息。收发器获取声音信息可以通过箱体10上的麦克风或者外接的话筒获取，也可以接收服务器或其他终端设备发送的声音信息。
处理器调整透明显示屏上展示的画面的方法可以基于本地的预设策略调整，也可以将收发器获取的信息发送到服务器，通过服务器的调整后，接收服务器反馈的信息。
一种实施例中，请参考图7，摄像头16与处理器电连接；摄像头16用于采集立体显示装置的周边环境的图像信息，并传输至处理器；处理器用于响应图像信息，调整透明显示屏20上展示的画面，例如虚拟人物的动画信息。通过摄像头16采集图像信息，基于立体显示装置自身的结构即可实现，操作便捷。
一种实施例中，请参考图3，处理器还用于在控制透明显示屏20上展示画面，例如虚拟人物的动画信息的过程中，通过扬声器17播放与画面匹配的音频信息，使得音画同步，人机交互效果好。
请参考图4、图6和图9，一种实施例中，腔室101内设有反射件50，反射件50设置于底板103，透明显示屏20显示的画面形成位于反射件50上的倒影。反射件50例如为反射膜。反射件50能够反射该倒影，透过箱体10的前板150能够看到透明显示屏20的画面及反射件50的倒影，实现立体显示。相较于在底板103上形成的倒影，设置反射件50能够使得倒影更清晰，立体效果更好。
一种实施例中，请参考图7，腔室101内还设有扩散件30，扩散件30设置在透明显示屏20背向箱体10的前板150的一侧。扩散件30例如为扩散膜，扩散膜可以与透明显示屏20平行，扩散膜也可以呈弯曲状。光源自扩散件30背向透明显示屏20的一侧朝向扩散件30发光。扩散件30用于接受光源的光并向透明显示屏20提供均匀的光线。扩散件30的设置，能够为透明显示屏20提供均匀的光线，使得透明显示屏20各处的亮度相同，显示的画面不受亮度的影响，显示效果好。
前文提到，透明显示屏20可采用拆除了背光模组的液晶显示屏，使得透明显示屏20呈透明状，透明显示屏20上显示的画面为不透明的，故而能在底板103或反射件50上形成画面的投影(倒影)。透明显示屏20缺少背光源，故而设置扩散件30，并通过外置光源向扩散件30发射光线，扩散件30将光源均匀后向透明显示屏20出射，使得透明显示屏20能够显示画面。无背光模组的液晶显示屏可以通过拆除背光模组的成品液晶显示屏实现，也可以在面板厂商处订购没有组装背光模组的液晶显示屏。液晶显示屏是成熟的产品，相对于需要改进显示屏本身的结构才能实现立体显示的现有3D显示方案而言，更为便捷。
一种实施例中，请参考图6，箱体10的前板150(透明部15)及透明显示屏20均为平板结构，箱体10的前板150与底板103垂直，在箱体10的侧板的正投影中，透明显示屏20呈第一直线，箱体10的前板150呈第二直线。如此设置，相较于复杂的曲面、弧面等设计，可进一步简化结构。
其他实施例中，箱体10的前板150可为平板结构，透明显示屏20可为曲面或弧面屏，能够显示出个性化的立体画面，具有独特的立体效果。
一种实施例中，请参考图10，前板150为非平板的结构，即，透明部15自边框部19朝向背板102方向凹进。从立体显示装置正面观察，前板150呈中间凹的结构。边框部19包括第一边框191和第二边框192，第一边框191连接底板和透明部15，第二边框192呈“匚”形，连接在透明部15的其余三个侧边，在垂直于透明部15的对应的侧板边沿的方向上，第一边框191的宽度大于第二边框192的宽度，使得透明部15距离底板的距离更远，透明部15具有较高的高度，便于透过透明部15观察箱体10内部。由于透明部15凹进的结构，还能提升纵深感，获得更好的视觉效果。
一种实施例中，请参考图1、图4和图6，透明显示屏20的底端21设置在底板103的中部，反射件50设置于箱体10的前板150(或透明部15)与透明显示屏20的底端21之间的底板103上。换而言之，反射件50设置于透明显示屏20的显示面一侧。由于透明显示屏20的显示面朝向箱体10的前板150，设置反射件50于透明显示屏20的显示面一侧，使得透过箱体10前板能看到清晰的倒影，增强立体感。
一种实施例中，请参考图4和图6，透明显示屏20的顶端22与箱体10的前板的距离不小于底端21与箱体10的前板的距离，以使透明显示屏20与底板103呈垂直或倾斜状。结合前述的一种实施例中的箱体10前板及透明显示屏20均为平板结构时，在侧板的投影中，第一直线与第二直线之间形成第一夹角，该第一夹角为透明显示屏10相较于底板103的倾斜角，第一夹角为0°-30°中的任意一个角度值。例如，第一夹角可以为0°、2°、4°、5°、7°、15°、25°、27°等均可，还可以为上述各相邻两个角度中间的任意值，例如，第一夹角为4.5°、7.8°、12.1°等均可，不再枚举。当第一夹角为0°时，透明显示屏20与底板103垂直，且与箱体10的前板平行，便于组装。第一夹角为除0°外的其他角度时，透明显示屏20相较于底板103倾斜，当透明显示屏20显示 画面时，透明显示屏20的画面各个区域与人眼之间具有不同的距离，使得观察到的画面具有纵深感，增强立体感。当透明显示屏20为曲面或弧面屏时，该倾斜角为透明显示屏20的底端21与顶端22的连线与箱体10的前板的夹角。
一种实施例中，请参考图7和图9，透明显示屏20的底端21与底板103转动连接。请参考图1至图4及图6，侧板上设置有调节件18。请参考图5和图6，调节件18与透明显示屏20的顶端22连接，调节件18用于带动透明显示屏20的顶端22在靠近或远离箱体10的前板的方向移动，以调节第一夹角的大小。
换而言之，本实施例中的透明显示屏20的倾斜角度可以调整。在透明显示屏20显示不同的画面时，调节件18调整透明显示屏20的倾斜角度，以达到更好的立体显示效果。
其他实施例中，透明显示屏20也可以设置为固定式，不可调整倾斜角度。
一种实施例中，请参考图2、图5和图7，侧板上开设有滑槽105，调节件18穿过滑槽105与透明显示屏20的顶端22连接。调节件18可以为螺栓、齿轮、拨杆等结构。设置滑槽105，即可实现在箱体10外调节透明显示屏20的倾斜角，操作便捷。
具体调节方式以调节件18为螺栓为例说明，螺栓的螺杆穿过滑槽105与透明显示屏20的顶端22螺接，螺栓的螺帽位于箱体10的侧板上。当需要调整透明显示屏20的倾斜角度时，转动螺帽，螺帽带动螺杆转动，使得透明显示屏20松动，移动螺帽在滑槽105内移动，透明显示屏20的顶端22跟随移动，底端21转动而不移动，到达位置后旋紧螺帽和螺杆，即可实现透明显示屏20的倾斜角度调整。调节件18可以设置在箱体10的一侧的侧板或者相对的两个侧板均设置，且在一侧的侧板上设置时，调节件18的数量可以为1个或多个，当调节件18的数量为多个时，能进行更为精细的调节。
一种实施例中，请参考图7和图9，底板103上设有凹槽109，凹槽109的开口朝向顶板，透明显示屏20的底端21的端面上设有突出的弧形凸起211，弧形凸起211容置在凹槽109。当底板103厚度足够时，凹槽109可以通过在底板103上挖槽实现，当底板103的厚度不足时，可以在底板103的局部位置冲压出一个弯曲部104，该弯曲部104围合形成该凹槽109。通过弧形凸起211与凹槽109的配合实现透明显示屏20的底端21与底板103的转动连接，结构简单，安装和拆卸方便。此外，透明显示屏20的边框也可容置在该凹槽109中，以隐藏 透明显示屏20的边框，使得在箱体10外看不到透明显示屏20的边框，以提升显示效果。
其他实施例中，底板103上不设凹槽，可设突出的转轴等结构，实现与透明显示屏20的转动连接即可。
请参考图11，一种实施例中，背板102还设有散热孔1021，散热孔1021的数量、形状、排布方式等可以有很多种变形，在此不再赘述。设置散热孔1021能对箱体10内进行散热，提升运行的可靠性。其他实施例中，在顶板120、侧板110上也可设散热孔。
以上所揭露的仅为本公开几种实施方式而已，当然不能以此来限定本公开之权利范围，本领域普通技术人员可以理解实现上述实施方式的全部或部分流程，并依本公开权利要求所作的等同变化，仍属于本公开所涵盖的范围。
