 本发明的最佳实施方式
下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能解释为对本发明的限制。
如图1至图11所示，本申请的实施例提供了一种屈光度调节装置，包括镜片安装部10、导向调节部20以及驱动部30，其中：
镜片安装部10用于安装镜片模组11，镜片模组11的结构可参照现有技术中的镜片模组结构，在此不做限定，例如，可以包括但不限于间隔设置的至少两个凸透镜。当用户佩戴上VR设备后，用户通过镜片的视觉焦点落在VR设备的取景目镜（未示出）上。通过调节镜片模组11与取景目镜的距离，即对应屈光度度数的变化，可以使得不同的视力的使用者均可以有清晰的视觉效果。
导向调节部20与镜片安装部10连接，以引导镜片安装部10的有序移动，导向调节部20可沿预设路径移动，使得镜片安装部10沿第一方向D1移动，第一方向D1为镜片模组11朝向取景目镜的方向，当镜片安装部10沿第一方向D1往复移动时，取景目镜与镜片模组11之间的距离发生变化即对应屈光度度数的变化。
驱动部30用于驱动导向调节部20沿预设路径移动，从而实现屈光度的自动调节，相比于手动调节，镜片模组11的屈光度可以更加方便的进行调整，无需反复穿戴VR设备，改善了用户体验，且操作起来更加简洁方便。
本申请所提供的实施例中，导向调节部20的预设路径为导向调节部20沿自身轴线为中心线的旋转运动，相比于线性移动，可以节省VR设备的内部空间，使得VR设备的体积能够更加轻薄，为驱动导向调节部20的正转或反转，一种可行的实施方式中，参照图6所示，驱动部30包括驱动电机31、蜗杆32、传动齿轮组33以及齿环23，驱动电机31的输出轴与蜗杆32轴接，以驱动蜗杆32转动，齿环23设于导向调节部20上，传动齿轮组33分别啮合于蜗杆32以及齿环23，传动齿轮组33用于传递驱动力变速传递至导向调节部20，驱动电机31正向转动，扭矩经由蜗杆32、传动齿轮组33、齿环23传递至导向调节部20，从而实现导向调节部20的正转，驱动电机31反向转动，扭矩经由蜗杆32、传动齿轮组33、齿环23传递至导向调节部20，从而实现导向调节部20的反转。
进一步地，参照图6所示，传动齿轮组33为双联齿轮，包括同轴设置的第一齿轮331以及第二齿轮332，第一齿轮331与第二齿轮332的模数相同，第一齿轮331与第二齿轮332的尺径存在差异，第一齿轮331的尺径大于第二齿轮332的尺径，第一齿轮331与蜗杆32啮合，第二齿轮332与齿环23啮合，从而改变驱动电机31的输出轴的转速，避免导向调节部20转速过快，降低镜片模组11的调节精度。
参照图8所示，导向调节部20上设置有容纳腔21，容纳腔21的内轮廓面与镜片安装部10的外轮廓面相适应，容纳腔21于导向调节部20的至少一端面形成敞口，容纳腔21的内表面上设有第一导向槽22，第一导向槽22的延伸方向与第一方向D1之间形成预设夹角，一种可行的实施方式中，第一导向槽22为螺旋槽，第一导向槽22沿第一方向D1螺旋状上升。
参照图5、图8以及图10所示，镜片安装部10经由敞口至少部分收容于容纳腔21内，镜片安装部10间隙配合于容纳腔21内，镜片安装部10的外表面上设有第一导向凸起12，第一导向凸起12间隙配合于第一导向槽22内，由于第一导向槽22倾斜于镜片安装部10的移动方向，在导向调节部20沿自身轴线为中心线发生正向旋转时候，第一导向槽22的底壁面与第一导向凸起12抵接，给予第一导向凸起12一个朝向取景目镜上的分力，从而使得镜片安装部10朝向靠近取景目镜的方向移动，在导向调节部20沿自身轴线为中心线发生反向旋转时候，第一导向槽22的顶壁面与第一导向凸起12抵接，给予第一导向凸起12一个背离取景目镜上的分力，从而使得镜片安装部10朝向背离取景目镜的方向移动，实现屈光度度数的变化。
本领域的技术人员可以知晓，也可以是镜片安装部10的外表面上设有第一导向槽22，导向调节部20的容纳腔21的内表面上设有第一导向凸起12，在此限定。
进一步地，参照图8以及图10所示，镜片安装部10的外表面上设有多个第一导向凸起12，多个第一导向凸起12环形等间隔设置于镜片安装部10的外表面，容纳腔21的内表面上设有多个第一导向槽22，多个第一导向凸起12与多个第一导向槽22一一对应设置，使得导向调节部20在进行旋转以及镜片安装部10在移动时，整体结构更加的稳定。
本申请所提供的实施例中，镜片安装部10的外表面上等间隔的环设有三个第一导向凸起12，容纳腔21的内表面上等间隔的环设有三个第一导向槽22，本领域的技术人员可以知晓，第一导向凸起12和第一导向槽22的数目均可以根据实际需要而定，可以严格的数量对应，每个第一导向凸起12均对应一个第一导向槽22，也可以具有差数，例如设置三个第一导向凸起12以及一个第一导向槽22，三个第一导向凸起12均间隙配合于此第一导向槽22内，在此不做限定。
参照图5所示，镜片安装部10以及导向调节部20均为筒体结构，导向调节部20同轴罩设于镜片安装部10的周向，在第一方向D1的法线方向上，导向调节部20与镜片安装部10至少部分相重叠，这样可以减少VR设备的占用空间，使得VR设备的体积能够更加轻薄。
本申请所提供的实施例中，参照图7所示，屈光度调节装置还包括限位部40，当导向调节部20移动至预设路径的起始端以及末端时，限位部40限制导向调节部20的进一步移动，从而限定镜片安装部10的移动范围，避免镜片安装部10移动过量，与VR设备内的其他部件发生干涉。
一种可行的实施方式中，继续参照图7所示，限位部40包括限位凸起25、第一行程开关41以及第二行程开关42，其中：
限位凸起25设于导向调节部20上随导向调节部20同步旋转。
第一行程开关41与第二行程开关42均与驱动部30内的驱动电机31电性连接，其中：
驱动电机31正向转动，带动导向调节部20正向旋转，限位凸起25随之旋转，第一行程开关41位于预设移动路径的末端，当限位凸起25移动至预设路径的末端时，限位凸起25触发第一行程开关41，驱动电机31停止工作或反向旋转，使得限位凸起25无法越过第一行程开关41，限位凸起25脱离第一行程开关41后，第一行程开关41回到初始状态。
驱动电机31反向转动，带动导向调节部20反向旋转，限位凸起25随之旋转，第二行程开关42位于预设移动路径的起始端，当限位凸起25移动至预设路径的起始端时，限位凸起25触发第二行程开关42，驱动电机31停止工作或正向旋转，使得限位凸起25无法越过第二行程开关42，限位凸起25脱离第二行程开关42后，第二行程开关42回到初始状态。
本申请所提供的实施例中，参照图1、图7以及图11所示，屈光度调节装置包括底板50、支撑座60以及压板70，支撑座60层叠于底板50上，在支撑座60上设有缺口，第一行程开关41以及第二行程开关42设置于缺口处暴露出的底板50上。
在底板50上还设有电机安装板80，驱动电机31以及传动齿轮组33均设于电机安装板80上，同时电机安装板80上设有轴承座，蜗杆32可转动的支撑于轴承座内。
压板70上设有通槽，导向调节部20可转动的设置于支撑座60上，且导向调节部20的一端自通槽内穿出，压板70用于限制导向调节部20沿第一方向D1以及第一方向D1的法线方向上的移动，使得导向调节部20只能转动，导向调节部20的外周面上套设有或一体成型有凸环24，齿环23以及限位凸起25均设有凸环24的外周面上，压板70与支撑座60之间形成有预设间隙，凸环24被压板70和支撑座60夹持于此预设间隙内。
支撑座60上凸设有凸筒61，凸筒61内设有第二导向槽62，第二导向槽62沿第一方向D1延伸，镜片安装部10同轴设置于导向调节部20内，且间隙配合于凸筒61内，镜片安装部10的外周向还设有第二导向凸起13，第二导向凸起13间隙配合于第二导向槽62内，镜片安装部10与导向调节部20之间通过第一导向槽22与第一导向凸起12、第二导向槽62以及第二导向凸起13实现导向连接，以引导镜片安装部10沿第一方向D1移动。
基于以上实施例，本申请还提供了一种VR设备，包括前述的屈光度调节装置，可实现屈光度自动调节，同时结构简单，组装简便，且满足量产性要求。
以上依据图式所示的实施例详细说明了本发明的构造、特征及作用效果，以上所述仅为本发明的较佳实施例，但本发明不以图面所示限定实施范围，凡是依照本发明的构想所作的改变，或修改为等同变化的等效实施例，仍未超出说明书与图示所涵盖的精神时，均应在本发明的保护范围内。
