[0028] 如图 1、 图 5和图 6所示, 镜筒 6、 7与透镜 8、 9相接触的一端设有圆环形的第二 台阶位 19, 第二台阶位 19的宽度为 1.5mm-4mm, 第二台阶位 19自由端的高度为 1 mm-3mm, 且第二台阶位 19自由端的直径小于透镜 8、 9的直径, 透镜 8、 9通过顶 盖 13、 14压于第二台阶位 19的自由端上, 在顶盖 13、 14与透镜 8、 9之间还设置 有环形的第二防尘片 16。 如图 1所述, 透镜 8、 9为双凸透镜, 且边缘设有一圈连 接环, 连接环下端由镜筒 6、 7上第二台阶位 19的自由端支撑, 上端贴设有第二 防尘片 16, 第二防尘片 16的厚度为 0.5-2mm。 第二防尘片 16同样优选采用与玻璃 透镜之间具有较好贴合力的泡棉材料, 用于防止虚拟现实头盔使用过程中泡棉 材料与透镜之间产生相对移动而使第二防尘片 16的防尘功能丧失。 顶盖 13、 14 为一体化的圆环形结构, 可分为水平设置的上盖 20和下盖 21以及竖直设置的侧 壁 22三部分, 上盖 20直径与第二防尘片 16相匹配且盖接在第二防尘片 16上, 下 盖 21直径与镜筒 6、 7上的第二台阶位 19的直径相匹配且盖接在第二台阶位 19上 , 第二台阶位 19与下盖 21之间设有第三防尘片 17 ; 侧壁 22的形状与第二台阶位 1 9自由端形状相匹配, 使侧壁 22能卡接于第二台阶位 19自由端外侧, 以此避免侧 壁 22与镜筒 6、 7之间的相对滑动。 侧壁 22两端分别无缝固定连接上盖 20和下盖 2 1, 使三者形成一体化结构。 本实施例中, 顶盖 13、 14与镜筒 6、 7优选采用质轻 、 化学性能稳定、 成本低的塑料材质制作, 同吋, 第三防尘片 17优选为对塑料 材质具有良好粘性的双面胶, 第三防尘片 17的厚度为 0.1mm-0.5mm, 宽度小于第 二台阶位 19的宽度。
[0029] 如图 3所示, 在下盖 21上下两侧还设有向外延伸的凸起 30, 对应的镜筒 6、 7上 下两侧设有与凸起 30相配的缺口 23, 通过将凸起 30卡合在缺口 23中, 能使顶盖 1 3、 14和镜筒 6、 7之间保持相对固定, 且凸起 30与缺口 23卡合后, 上盖 20与透镜 8、 9上表面的距离小于第二防尘片 16的厚度。 通过凸起 30与缺口 23的卡合固定 作用以及双面胶的粘力作用, 使上盖 20能对第二防尘片 16产生一定的压力使其 在上盖 20与透镜之间产生压缩变形而实现上盖 20与透镜之间的密封防尘, 同吋 , 由于双面胶对下盖 21与镜筒的良好粘力和凸起 30与缺口 23的卡合固定给予的 压力, 使下盖 21与镜筒之间也可形成严密的防尘层, 从而彻底防止了从透镜 8、 9上下表面进入灰尘到显示模块 11、 12内部。 经实验验证, 通过以上设置, 能使 本实施例达到最优防尘和固定效果, 使虚拟现实头盔具有高度的一致性和整体 性, 能大大提高产品的用户体验和使用寿命。
[0030] 组装后的显示模块 11、 12为相互独立的一体化结构, 具体使用吋, 显示模块 11 、 12中的显示屏 2、 3为不同的两块屏幕, 分别与控制系统相连输出相对应的虚 拟现实视频图像, 用户在显示模块 11、 12中的透镜 8、 9中分别观看到显示屏 2、 3上的视频图像, 并在脑海中形成虚拟现实场景, 从而使本实施例实现虚拟现实 显示工功能。 当需要进行瞳距调节吋, 可通过拨动调节装置的拨圈 27调节显示 模块 11、 12之间的距离, 进而使透镜 8、 9之间的距离得到调节, 以此实现瞳距 调节功能。 由于第一防尘片 15、 第二防尘片 16、 第三防尘片 17的设置, 使外界 与显示模块 11、 12中的显示屏 2、 3之间形成了严密的防尘层, 同吋, 通过为第 一防尘片 15、 第二防尘片 16、 第三防尘片 17选择合适的材料, 保证了在虚拟现 实头盔使用过程中或摔碰过程中依然能产生防尘性能。
[0031] 以上结合附图对本发明的实施例进行了描述, 但是本发明并不局限于上述的具 体实施方式, 上述的具体实施方式仅仅是示意性的, 而不是限制性的, 本领域 的普通技术人员在本发明的启示下, 在不脱离本发明宗旨和权利要求所保护的 范围情况下, 还可做出很多形式, 这些均属于本发明的保护之内。
