具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
在本发明的描述中，应当理解的是，本发明中采用术语“第一”、“第二”等来描述各种信息，但这些信息不应限于这些术语，这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本发明范围的情况下，“第一”信息也可以被称为“第二”信息，类似的，“第二”信息也可以被称为“第一”信息。
另外，需要说明的是，本实施例中，“前”及“后”分别为：用户佩戴该眼镜式虚拟显示器佩戴时，位于用户的前面的一侧为“前”，位于用户的后面的一侧为“后”。
实施例一
如图1所示，本实施例提供一种眼镜式虚拟显示器，其包括左镜框1及右镜框2，左镜框1与右镜框2的结构相同，且呈对称分布，所述左镜框1及所述右镜框2上分别设有一近眼显示系统，左镜框及右镜框均包括镜框本体21及镜腿22，两个所述镜框本体21的一端相连， 所述镜框本体21的另一端并位于所述镜框本体21的后侧。
附图2中示出了该眼镜式虚拟显示器的右侧部分结构，所述近眼显示系统包括微显示屏3、透镜组4及成像装置5，微显示屏3设于所述镜腿22的后端，用于发射图像光束，透镜组4设于所述微显示屏3的出射光路上，透镜组4用于接收所述图像光束并将其聚焦成汇聚光束，且所述透镜组4也设于所述镜腿22的后端，成像装置5设于所述透镜组4的出射光路上，用于接收所述汇聚光束并成像，最终能够聚焦至人眼，所述成像装置5与所述镜框本体21相连。
基于上述技术方案，微显示器3朝向透镜组4发射范围较大的图像光束，图像光束投射至透镜组5后聚焦成范围较小的汇聚光束，以将图像缩小，汇聚光束沿着镜腿22的方向传输后投射至成像装置5，并经成像装置5传输后以将缩小的图像再次放大，成像为可视图像，最后聚焦至人眼，使得人眼能够观察到视野范围较大的图像；具体地，左镜框1上成像形成的可视图像聚焦至左眼，右镜框2上成像形成的可视图像聚焦至右眼。
上述技术方案中，将微显示屏3及透镜组4等元器件均布置于镜腿22的后端，使得重心往后移，且前部结构变得简洁，当用户佩戴上该虚拟显示器后，能够减轻对鼻子的压力，有效提升用户的使用体验；且将微显示屏3及透镜组4等元件后置能够简化装配工艺，降低生产及维护成本。
进一步地，本实施例中，为了将微显示屏3发出的图像缩小，以适应于在尺寸狭长的镜腿22中传输，所述透镜组4为准直透镜组。
本实施例中，为了能够聚焦图像光束，所述透镜组4包括沿所述图像光束的方向依次分布的第一透镜41及第二透镜42，所述第一透镜41及所述第二透镜42均为凸透镜。
进一步地，为了能够将各元器件合理布局于镜腿22的后部，本实施例中，在所述微显示屏3与所述透镜组4之间还设有第一反射镜组6，所述微显示屏3发出的图像光束经所述第一反射镜组6反射后，投射 至所述透镜组4。示例性地，如图2所示，第一反射镜组6包括一个反射镜，微显示屏3发出的图像光束先经该反射镜反射后，再投射至透镜组4，通过适当增加镜腿22前端的宽度，能够较大地缩短镜腿的长度。
本实施例中，所述微显示屏3用于产生图像，可以为LED、OLED、MicroLED、LCOS、DLP及MEMS中的任意一种。
本实施例中，为了控制微显示屏3产生图像，所述近眼显示系统还包括驱动电路组件(附图中未示出)，所述驱动电路组件同样设于所述镜腿的后端，且驱动电路组件与所述微显示屏3电连接，能够控制微显示屏3发出不同的图像光束；由于驱动电路组件也设置于镜腿22的后端，从而能够进一步减轻该眼镜式虚拟显示器前部的重量，并使得安装及维护均较便捷。
具体地，本实施例中的成像装置5为第二反射镜组，该第二反射镜组由多个反射镜组成。
示例性地，如图2所示，该第二反射镜组包括凸面反射镜51、凹面反射镜52及一个或多个平面反射镜53，所述一个或多个平面反射镜53均设于所述镜框本体21的内部，所述凹面发射镜52贴设于所述镜框本体21的前侧面，两所述镜框本体21相连的一端或者两所述凹面反射镜52相向的一侧均设有鼻托7，所述凸面反射镜51设于所述鼻托7上；所述汇聚光束经各所述平面反射镜51及所述凸面反射镜53依次反射后，投射至所述凹面反射镜52。通过设置相对的凸面反射镜53及凹面反射镜52，能够使得用户看到视野范围较大的图像，以提升视觉体验。
作为可替换方案，上述各平面反射镜53及凸面反射镜51均可设置为全反射棱镜。
示例性地，本实施例中的凹面反射镜52可以为透明镜或半透明镜，能够将现实中的图像和虚拟图像更好地融合，从而实现虚拟增强现实的视觉效果。
优选地，为了简化结构且合理布局各部件，所述第二反射镜组包括两个所述平面反射镜53，其中一所述平面反射镜53设于所述镜框本体21与所述镜腿22相连的一端，另一所述平面反射镜53设于所述镜框本体22的另一端。
本实施例中的眼镜式虚拟显示器具体的工作过程为：微显示屏3发射出范围较大且平行的图像光束，经第一反射镜组6反射至透镜组4，透镜组4将图像光束缩小成范围较小且平行的汇聚光束，汇聚光束依次经第一反射镜53及第二反射镜反射51，然后投射至凸面反射镜53，凸面反射镜53将汇聚光束变成发散状的光束投射至凹面反射镜52上，从而放大为视野范围较大的可视图像，最终凹面反射镜52将该可视图像聚焦至人眼。
实施例二
如图3及图4所示，本实施例提供另一种眼镜式虚拟显示器，其与实施例一的区别仅在于：本实施例中的成像装置5为全息光波导片，所述全息光波导片贴设于所述镜框本体21的前侧面，全息光波导片的作用是将经透镜组4缩小的图像再次放大并反射进入人眼。
本实施例中，由于同样将微显示屏3及透镜组4设于镜腿22的后端，因此具有实施例一中的全部有益效果，在此不作赘述。
另外，还可以将上述全息光波导片替换成阵列光波导片。
综上，本发明实提供一种眼镜式虚拟显示器，其将微显示屏及透镜组等元器件均布置于镜腿的后端，使得重心往后移，且前部结构变得简洁，当用户佩戴上该虚拟显示器后，能够减轻对鼻子的压力，有效提升用户的使用体验。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本发明的保护范围。
