下文的公开提供了许多不同的实施方式或例子用来实现本发明的不同结构。为了简化本发明的公开，下文中对特定例子的部件和设置进行描述。当然，它们仅仅为示例，并且目的不在于限制本发明。此外，本发明可以在不同例子中重复参考数字和/或参考字母，这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施方式和/或设置之间的关系。此外，本发明提供了的各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的应用和/或其他材料的使用。
请参阅图1至图5，本发明实施方式的电子装置1000可以是头戴显示装置，用于进行视频播放、游戏等功能。电子装置1000可包括有耳机及显示组件。其中，显示组件包括有外壳体及容置于该外壳体内的显示装置100。当然，还包括未示出的电路及电池等相关元件。显示装置100装置包括镜头模组10、图像产生模组20和调节组件30。一般地，对于头戴显示装置，显示装置100包括两镜头模组10、两图像产生模组20和两调节组件30以适用于双目。下 面以一组镜头模组10、图像产生模组20和调节组件30进行示例性说明。
具体地，镜头模组10和图像产生模组20相对设置并活动连接，可以理解地，图像产生模组20的移动方向朝向或背向镜头模组10。一般地，图像产生模组20的中心轴与镜头模组10的光轴重合，图像产生模组20产生的图像由镜头模组10向预定方向进行投射，一般地，投射方向为人眼方向。调节组件30与图像产生模组20配合，从而，调节组件30能够调节图像产生模组20与镜头模组10之间的距离，具体地，图像产生模组20上安装有固定轴21，调节组件30上开设有滑槽31，滑槽31与固定轴21相配合，固定轴21套设于滑槽31内并可伸出滑槽31，滑槽31限定了固定轴21的行程，也即是图像产生模组20和镜头模组10相对移动的行程。操作中，调节组件30能够绕图像产生模组20的中心轴转动，对调节组件30施加驱动力使得调节组件30绕中心轴转动，并通过滑槽31对固定轴施力以使得固定轴21在滑槽31内移动，进而带动图像产生模组20移动。滑槽31可以是矩形状或其他样条曲线，在此不做限制。
如此，本发明实施方式的显示装置100和电子装置1000允许用户调节屈光度，以适用于不同用户使用。调节组件30与图像产生模组20通过滑槽31对固定轴21施力，二者相互配合实现图像产生模组20和镜头模组10的相对移动。
在某些实施方式中，图像产生模组20包括顶壁和自顶壁沿垂直方向延伸的两侧壁，固定轴21包括2个，每个图像产生模组20的侧壁上安装有1个固定轴。如此，可使得图像产生模组20的受力点位于模组的两侧，相对于受力点位于顶壁的设计，模组整体受力均匀，可有效防止施力点集中导致图像产生模组20在移动中可能发生的偏转，进而由偏转带来的倾斜致使产生的图像发生形变，影响观影效果。
进一步地，在某些实施方式中，固定轴21与图像产生模组20的中心轴位于同一水平面上。可以理解，固定轴21的位置固定，作为受力点驱动图像产 生模组20移动，当固定轴21与中心轴位于同一水平面时，可使得图像产生模组20所受的驱动力关于中心轴对称，在受力均匀的情况下，图像产生模组20能够保证在移动方向上的平稳运动而不会发生偏转。
在某些实施方式中，滑槽31相对图像产生模组20倾斜设置。
可以理解地，当对调节组件30施力进而带动滑槽31移动时，倾斜设置可使得滑槽31对固定轴21施力，进而驱动图像产生模组20移动。在这样的实施方式中，调节组件30的设置方向与图像产生模组20的移动方向垂直，也即是说，当调节组件30沿图像产生模组20中心轴方向转动时，可驱动图像产生模组20沿中心轴方向移动。
在某些实施方式中，镜头模组10包括镜筒以及镜片组件。镜片组件包括有一个或多个镜片。镜筒通常具有入射口及出射口，入射口面向图像产生模组20的一侧，进入入射口的光线通过镜片组件并发生折射与反射，最终从出射口射出。一般地，图像产生装置20包括有显示器，例如LED显示器或OLED显示器，并且，显示器设置在入射口上。如此，显示器显示的图像的光线进入入射口，并由镜片组向预定的方向投射，从出射口射出的光线进人眼，人眼将能看到显示器显示的图像的放大虚像。
在某些实施方式中，调节组件30包括转动部32和驱动部33。其中，滑槽31开设于转动部32，驱动部33与转动部32配合。
具体地，转动部32可以是圆环状，套设于图像产生模组20的外部，滑槽31开设于转动部32上，装配时，可先将转动部32套设在图像产生模组20上，进而将固定轴21通过滑槽31安装在图像产生模组20的侧壁上。
驱动部33与转动部32可以通过锥齿轮配合，如此，可以将施力方向由图像产生模组20的径向转换为轴向方向，通过转动驱动部33带动转动部32的转动，进而通过滑槽31对固定轴21施力。
可以理解地，为增加操作时的稳定性，图像产生模组20两侧壁均安装有固定轴21，两侧的滑槽31的延长线相接应当构成螺旋线状，并且两侧的滑槽 31开设高度相异。例如，在某一极限位置时，位于同一水平位置两固定轴21，可分别位于相对应的滑槽31的顶端及底端。从而实现通过转动部32的转动驱动固定轴21在滑槽31中的相对移动，进而带动图像产生模组20的轴向运行。
当然，调节组件30并不限于本实施方式所公开的方式，例如，另一些示例中，调节组件30可仅包括转动部32，此时，转动部32作为施力部件。
在某些实施方式中，显示装置100还包括固定板40，固定板40与镜头模组10固定连接。
固定板40与镜头模组10可通过螺钉、卡扣等方式固定连接，当然还可以粘接等方式，在此不做限制。具体地，固定板40与镜筒固定连接。可以理解，用户通过镜头模组10观看影像，因此，镜头模组10与图像产生模组20间的相对移动也即是镜头模组10固定，而图像产生模组20移动。
在某些实施方式中，显示装置100还包括有限位板50，限位板50罩设于固定板40上并形成收容空间。
进一步地，限位板50形成有通孔51.驱动部33包括转轴34，转轴34穿设通孔51，驱动部33收容于收容空间内。
进一步地，转动部32部分收容于收容空间内。
具体地，转轴34用于可作为施力处，相对于直接对驱动部施力操作方便。驱动部33与转动部32通过锥齿轮配合，限位板50可对啮合部起到保护作用，防止其他异物落入该部分而导致调节组件30的驱动异常，也即是说，驱动部33和转动部32至少相接的部分共同收容于收容空间内。
固定板40还开设有安装孔，以用于安装驱动部33，具体地，转轴34可自驱动部33本体穿过，两端部中的一端与安装孔配合，使得驱动部33安装在固定板40上，另一端部则穿设限位板50的通孔51。
在这样的实施方式中，调节组件30还包括旋钮35，旋钮35与转轴34穿设通孔51的端部同轴连接。如此，转动旋钮35将带动驱动部33转动，进而带动转动部32转动，并由滑槽31驱动固定轴带动图像产生模组20沿轴向移 动。旋钮35的施力面积相较于转轴34的端部更大，方便用户操作。
在本说明书的描述中，参考术语“一个实施方式”、“某些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合所述实施方式或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施方式，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施方式进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
