如图1至图8所示，本申请提供了一种VR眼镜，包括底板1、屏幕支架2、第一密封部3和第二密封部4，屏幕支架2固定于底板1上，底板1上对称开设有两个透光孔11，屏幕支架2的边缘具有垂直于底板1的第一侧边21；第一密封部3和第二密封部4均由硅胶材料制成且分别与两个透光孔11位置对应，第一密封部3和第二密封部4均与第一侧边21的延伸方向同侧设置；硅胶材料在使用过程中受到的摩擦力很小，同时硅胶材料本身的耐磨性更高，且不易老化，利用硅胶材料作为第一密封部3和第二密封部4的材料，可以更加有效的对VR眼镜内部进行密封，避免灰尘或水渍进入VR眼镜内部，导致成像效果模糊，用户体验较差。
VR眼镜还包括第一镜筒5和第二镜筒6，第一镜筒5通过第一密封部3与一个透光孔11连通，第二镜筒6通过第二密封部4与另一个透光孔11连通，第一镜筒5和第二镜筒6上均设置有镜片8；其中两个镜片8分别设置在第一镜筒5和第二镜筒6上远离透光孔11的一端，用户使用VR眼镜时，镜片8靠近人眼一侧使用。第一镜筒5和第二镜筒6均与透光孔11连通，用户通过第一镜筒5和第二镜筒6能够清晰的观看到影像。但是每个用户的瞳距不同，所以在不同用户使用VR眼镜的过程中，需要调节第一镜筒5和第二镜筒6之间的距离，才能够使观看效果达到最佳。在对第一镜筒5和第二镜筒6之间的距离进行调节的过程中，随着第一镜筒5和第二镜筒6之间的距离的减小或增大，第一密封部3和第二密封部4会产生形变，而由硅胶材料制成的第一密封部3和第二密封部4在形变过程中摩擦极少，且硅胶材料具有耐磨和耐腐蚀的特性，能够避免在日常使用过程中汗渍、水渍、灰尘等杂质的侵蚀，能够长期且有效的对第一镜筒5与底板1之间以及第二镜筒6与底板1之间进行密封，保证了VR眼镜成像效果清晰的同时，延长了VR眼镜的使用寿命。
VR眼镜还包括传动机构7，传动机构7为有级调节机构，传动机构7靠近屏幕支架2的第一侧边21设置，第一镜筒5和第二镜筒6能够通过传动机构7相向移动。有级调节方式的传动机构7可以使调节过程具有顿挫感，相当于在调节第一镜筒5和第二镜筒6之间的距离的过程中设置了不同的档位，当用户拨动第一镜筒5或第二镜筒6时，传动机构7的有级调节方式能够使用户调节第一镜筒5或第二镜筒6的过程更加简便，通过传动机构7使用户在选定瞳距后，第一镜筒5和第二镜筒6之间的距离相对固定，误触第一镜筒5或第二镜筒6也不会改变瞳距，提高了用户的使用感受。
在一些实施例中，传动机构7包括第一齿轮71、固定轴72、齿轮支架73和弹簧74，固定轴72垂直固定于底板1上，弹簧74处于压缩状态的套设于固定轴72上，齿轮支架73在水平方向上固定的设置于固定轴72上，第一齿轮71可转动的设置于固定轴72上，第一齿轮71朝向齿轮支架73的一侧为第一配合面711，齿轮支架73朝向第一齿轮71的一侧为第二配 合面731，第一配合面711和第二配合面731通过弹簧74相抵顶，第一配合面711和第二配合面731上均具有相适配的面齿轮77；弹簧74使第一配合面711始终抵顶在第二配合面731上，当第一齿轮71转动时，第一配合面711旋转，第一配合面711和第二配合面731上的面齿轮77发生错位。例如第一配合面711上的面齿轮77具有第一凸棱，第二配合面731上的面齿轮77具有第一凹槽、第二凹槽和第二凸棱，第一凸棱初始状态位于第一凹槽内，当第一齿轮71转动时，第一凸棱随第一齿轮71转动，第一凸棱由第一凹槽向第二凹槽移动，此时弹簧74被持续压缩，使第二凸棱位置降低，从而使第一凸棱能够越过第二凸棱进入第二凹槽内，完成一档间距的调节。其中为了避免第一齿轮71沿竖直方向移动，可以将固定轴72设置为上半部分直径小于下半部分直径的结构，通过上下两部分的连接面卡接第一齿轮71，同时在齿轮支架73的中部开设尺寸较大的通孔732，便于齿轮支架73套设在固定轴72的下半部分上。
第一镜筒5靠近第一侧边21的一侧设置有第一齿条75，第二镜筒6靠近第一侧边21的一侧设置有第二齿条76，第一齿轮71设置于第一齿条75和第二齿条76之间，当第一齿轮71处于转动状态时，第一配合面711和第二配合面731上的两个面齿轮77相啮合，第一齿条75和第二齿条76被配置为能够带动第一镜筒5和第二镜筒6相互靠近或远离。第一齿条75和第二齿条76相对设置，并分别与第一齿轮71相啮合，用户需要调节第一镜筒5和第二镜筒6之间的距离时，通过拨动第一镜筒5或第二镜筒6，使第一齿条75或第二齿条76带动第一齿轮71转动，从而实现对第一镜筒5和第二镜筒6之间距离的调节。例如，当需要增大第一镜筒5和第二镜筒6之间的距离时，只需将第一镜筒5向远离第二镜筒6的方向拨动，第一齿条75带动第一齿轮71转动，第二齿条76被带动向远离第一镜筒5的方向移动，从而使第二镜筒6朝向远离第一镜筒5的方向移动，加快了调节速度，此时通过弹簧74、第一配合面711和第二配合面731之间的相互作用，实现了有级调节，使客户清晰的感受到了各个档位的存在，使得用户调节第一镜筒5和第二镜筒6之间的距离时更加方便。
其中，第一齿轮71在竖直方向上不会发生位移，只通过第一齿条75和/或第二齿条76带动第一齿轮71在水平方向上转动；齿轮支架73在水平方向上不会发生转动，但是会通过压缩弹簧74实现在竖直方向上位置的变化。
在一些实施例中，第一侧边21上设置有第一滑杆23，第一镜筒5和第二镜筒6可滑动的设置于第一滑杆23上。通过第一滑杆23，可以使第一镜筒5和第二镜筒6在进行距离调节的过程中，始终保持水平状态，不会发生偏移或是倾斜。保证了VR眼镜在使用过程中的稳定性，提高了VR眼镜的视觉成像效果。
在一些实施例中，第一镜筒5朝向第一侧边21的一侧设置有第一安装部51，第一齿条75设置于第一安装部51上，第二镜筒6朝向第一侧边21的一侧设置有第二安装部，第二齿条76设置于第二安装部上，第一安装部51和第二安装部均水平向第一侧边21延伸后向底板1方向弯折，第一滑杆23穿设于第一安装部51和第二安装部上靠近底板1的一端上。用户可以通过推动第一安装部51或第二安装部调节第一镜筒5和第二镜筒6之间的距离，同时第一滑杆23作为第一镜筒5和第二镜筒6调节位置时候的辅助稳定结构，使第一镜筒5和第二镜 筒6之间的距离在进行有级调节过程中，第一镜筒5和第二镜筒6均始终平行于第一侧边21移动。
在一些实施例中，屏幕支架2上与第一侧边21相对的一侧为第二侧边22，第一镜筒5朝向第二侧边22的一侧设置有第三安装部52，第二镜筒6朝向第二侧边22的一侧设置有第四安装部，第三安装部52和第四安装部均水平向第二侧边22延伸后向底板1方向弯折，第二侧边22上对应第三安装部52处固定有第二滑杆26，第二滑杆26穿设于第三安装部52的底部，第二侧边22上对应第四安装部处固定有第三滑杆27，第三滑杆27穿设于第四安装部的底部。第三安装部52和第一安装部51配合，第四安装部和第二安装部配合，进一步便于用户推动第一镜筒5和第二镜筒6。同时第二滑杆26和第三滑杆27之间设置有间隙，通过第二滑杆26和第三滑杆27能够进一步辅助有级调节过程中第一镜筒5和第二镜筒6位置的稳定，避免出现第一镜筒5与第一侧边21之间的距离以及第二镜筒6与第一侧边21之间的距离发生改变，而导致的用户体验下降。
其中第一安装部51、第二安装部、第三安装部52和第四安装部上均设置有加强筋，加强筋由第一镜筒5和第二镜筒6的筒身向底板1方向延伸设置。加强筋可以加强VR眼镜整体的结构强度，同时在进行第一镜筒5和第二镜筒6之间距离调节的过程中，加强筋可以起到防滑作用，便于用户推动第一镜筒5或第二镜筒6。
在一些实施例中，第一密封部3和第二密封部4的中部均向远离周侧的方向凸出呈灯笼状，在第一镜筒5和第二镜筒6之间的距离发生改变的状态下，第一密封部3和第二密封部4均产生形变。呈灯笼状的凸出结构可以增大第一密封部3和第二密封部4的形变余量，使第一镜筒5和第二镜筒6之间的可调节距离增大，以适应不同用户的不同瞳距。同时灯笼状结构也能够增大第一密封部3和第二密封部4的形变次数，延长了第一密封部3和第二密封部4的使用时间，也就是进一步增加了VR眼镜的使用寿命。
在一些实施例中，屏幕支架2上对应第一密封部3的位置设置有第一防尘片24，屏幕支架2上对应第二密封部4的位置设置有第二防尘片25。如屏幕支架2远离镜片8的一侧设置有屏幕，当有灰尘通过屏幕支架2与屏幕之间的连接处进入VR眼镜内部时，第一防尘片24和第二防尘片25能够起到吸附灰尘的作用，第一防尘片24与屏幕之间以及第二防尘片25与屏幕之间均设置有间隙，当用户使用VR眼镜时，用户聚焦于屏幕，此时第一防尘片24和第二防尘片25上的灰尘会被模糊化，提高了VR眼镜整体的视觉效果，提高了用户的使用感受。
在一些实施例中，环绕透光孔11周侧垂直于底板1设置有限位板9，第一防尘片24和第二防尘片25设置于限位板9上，限位板9位于第一镜筒5和第二镜筒6之间的部分相互靠近。限位板9用于对第一防尘片24和第二防尘片25进行限位。
在一些实施例中，第一镜筒5与第一密封部3连接的一侧向周侧延伸形成有第一安装板，第一密封部3上设置有第一安装槽，第一安装板嵌入第一安装槽内；第一安装板和第一安装槽配合，可以提高第一密封部3与第一镜筒5之间的连接强度，在移动第一镜筒5的过程中，避免第一镜筒5与第一密封部3脱离，同时也进一步提高了第一密封部3对第一镜筒5内部 的密封效果。
第二镜筒6与第二密封部4连接的一侧向周侧延伸形成有第二安装板，第二密封部4上设置有第二安装槽，第二安装板嵌入第二安装槽内。第二安装板和第二安装槽配合，可以提高第二密封部4与第二镜筒6之间的连接强度，在移动第二镜筒6的过程中，避免第二镜筒6与第二密封部4脱离，同时也进一步提高了第二密封部4对第二镜筒6内部的密封效果。
在一些实施例中，底板1上设置有两根固定柱12，两根固定柱12分别设置于固定轴72的两侧，齿轮支架73的两端均设置有通孔732，固定柱12穿设入通孔732内。齿轮支架73通过两根固定柱12和两个通孔732的配合进行水平方向上的限位，齿轮支架73压缩弹簧74的过程中，齿轮支架73与第一齿轮71之间不会发生脱扣的情况，使第一配合面711能够与第二配合面731保持啮合。
在一些实施例中，第二侧边22上设置有断裂部，断裂部对应第一镜筒5和第二镜筒6的中线处。在用户使用VR眼镜的过程中，正确的佩戴方式为第一侧边21靠近额头，第二侧边22靠近鼻子，第二侧边22上的断裂部防止第二侧边22压迫鼻翼，提高了用户的使用感受。
