 随着带宽的升级,沉浸式的虚拟现实效果让媒体和厂商对VR领域趋之若鹜,但近视怎么办?对于近视眼来说,同时戴眼镜和VR头盔,会极大地削弱沉浸感。在戴上VR头盔之后,更易产生晕动症,或者说,晕的程度更严重。

针对这一市场趋势,兆威机电对VR眼镜(VR头盔)电机齿轮箱也做了升级设计,通过微型对焦电机的往复直线运动进行动态变焦的行星齿轮箱来控制镜片到屏幕的距离。

现有的VR眼镜多数采用以智能手机为代表的智能多媒体播放终端作为计算和显示的单元,安装在眼镜的前部。在VR眼镜中,具有两组分别与使用者的左眼和右眼相对应的透镜组件,由于不同使用者的双眼的瞳距各不相同,若透镜组件之间的距离恒定不变,必然会导致近视VR玩家在穿戴VR眼镜时难以获得较好的体验感受。

VR眼镜瞳距智能调节齿轮箱结构

为解决以上问题,兆威在VR眼镜的瞳距调节机构上加入了采用微型对焦电机的往复直线运动进行动态变焦的伸缩齿轮箱结构带动偏心轮转动,偏心轮使眼镜架(头盔框架)产生振动,电机通过VR眼镜的瞳距调节齿轮箱结构智能调节VR眼镜的两组透镜组件的间距,直至与使用者的瞳距相匹配,当用户再次戴上眼镜之后,VR眼镜内置传感器会将数据转换为电力驱动装置,将微型电机的旋转运动转变为推杆的直线运动,从而带动VR眼镜的前后两层镜片根据适合用户的聚焦度数来进行自动对焦,智能控制镜片到屏幕的距离,完成视觉清晰成像的目的。

这款VR眼镜瞳距调节齿轮箱产品,拥有二级、三级、四级传动变化可根各性能的步进(电机)马达的传动需求更换减速比及调整齿轮箱的输入转速及力矩,从传动方式上解决VR眼镜调节的各级智能传动稳定性需求。此外,其行星齿轮的模数小。在不同湿度、温度环境下,转子部分以及转子里面的步进马达测试结果显示,使用寿命长。

兆威VR眼镜瞳距调节齿轮箱解决方案,让高度近视也能玩VR。VR设备的传动结构配上瞳距调节齿轮箱在进行瞳距调节时结合传感器会获取移动轨迹长度和移动方向,根据瞳孔的距离识别出你适合的屏幕,作为显示的双眼画面同步调节的参数,智能调节瞳距。虚拟现实技术是仿真技术的一个重要方向,随着5G商用场景的布局,VR整个产业链包括硬件、软件、应用和服务也在升级。谁解决了VR眼镜的痛点,谁将赢得市场。兆威在VR微型传动系统上帮助实现其智能升级,可以根据VR厂商的产品需求,定制各种类型的微型齿轮箱传动系统解决方案去设计、研发、生产对应的齿轮箱产品。
