具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
参见图1，为本申请实施例提供的一种眼镜，包括调节机构。利用该调节机构可以针对左右眼同步调节透镜与屏幕之间的距离，以达到较佳的观看效果。
如图1所示，该眼镜包括第一支架1，在所述第一支架1的同侧上并排设置的两个固定筒10，以及与所述两个固定筒10一对一同轴套设且螺纹连接的两个镜筒3。所述两个镜筒3分别对应使用者的左右两眼。固定筒10与镜筒3同轴套设且螺纹连接，利用固定筒10与镜筒3之间的螺纹配合，当镜筒3转动时，可以使镜筒3与固定筒10沿所述镜筒3的轴向相对直线移动。
所述眼镜的调节机构还包括分别固定在每个所述镜筒3的外周且与所述镜筒3同轴设置的两个镜筒齿轮31；以及同时啮合于所述两个镜筒齿轮31的同步齿轮4，其中所述同步齿轮4的转动轴向平行于所述镜筒3的轴向。利用同步齿轮4与两个镜筒齿轮31的配合，当其中一个镜筒3转动时，可以带动另外一个镜筒3转动，以使两个镜筒3同步转动，进而可以使两个镜筒3与两个固定筒10沿镜筒3的轴向相对同步直线移动，实现左右眼的同步。同步齿轮4与两个镜筒3的转动轴向相互平行，结构简单。此外，利用镜筒3与固定筒10之间的螺纹，可以直接将镜筒3的转动转化为镜筒3与固定筒10的相对纵向移动，可靠性高。
在一种实现方式中，第一支架1上设置有显示屏幕，镜筒3上设置有透镜。固定筒10与镜筒3轴向相对移动时，可以改变显示屏与透镜之间 的距离，从而适用不同使用者的需求。此处，在其他实现方式中，也可以是，第一支架1的固定筒10上设置有透镜，镜筒3上设置有显示屏幕。
在一种实现方式中，为了使同步齿轮4更加稳固，可以将同步齿轮4通过螺钉螺纹连接于第一支架1上。其中，所述螺钉的一端与所述同步齿轮4固定连接，所述螺钉的另一端与所述第一支架1通过配合螺纹相连接，即，所述螺钉的另一端螺纹穿设于所述第一支架1中。当同步齿轮4随镜筒3转动时，同步齿轮4相对于支架1沿轴向直线移动，同时使螺钉通过与所述第一支架1的配合螺纹进行轴向的同步直线移动。进一步地，为了提高用户体验，可以在第一支架1的正对螺钉的位置处朝向同步齿轮4设置一凸起，所述螺钉的另一端螺纹穿设于所述凸起中。
在另一种实现方式中，还可以包括第二支架来固定同步齿轮4的位置并保护眼镜的内部结构。参见图2和图3，图2示出了具有第二支架的眼镜的调节机构的示意图，图3示出了图2所示实施例中的调节机构隐去第二支架的结构示意图。如图2和图3所示，眼镜的调节机构包括第一支架1、第二支架2及两个镜筒3；第一支架1与第二支架2沿镜筒3的轴向排布设置。两个镜筒3并排设置，分别对应使用者的左右两眼。
第一支架1上设置有两个固定筒10，固定筒10与镜筒3同轴套设且螺纹连接。利用第一支架1可以使得两个固定筒10连接为一个整体，便于整体移动，同时可以对固定筒10的周向进行限位，防止固定筒10转动时带动镜筒3转动。利用固定筒10与镜筒3之间的螺纹配合，当镜筒3转动时，可以使得镜筒3和固定筒10沿轴向相对直线移动。
镜筒3的外周固定有镜筒齿轮31，镜筒齿轮31与镜筒3同轴设置。两个镜筒3均可绕自身轴向转动地连接于第二支架2，以随着镜筒3的转动，使第二支架2与第一支架1沿所述镜筒3的轴向相对直线移动。第二支架2上还转动设置有同步齿轮4，同步齿轮4的转动轴向平行于所述镜筒3的轴 向，同步齿轮4同时啮合于两个镜筒齿轮31。利用同步齿轮4与两个镜筒齿轮31的配合，当其中一个镜筒3转动时，可以带动另外一个镜筒3转动，以使两个镜筒3同步转动，进而可以使得两个镜筒3与两个固定筒10及第一支架1沿镜筒3的轴向相对同步直线移动，实现左右眼的同步。同步齿轮4与两个镜筒3的转动轴向相互平行，不需要锥齿转换，不需要多级过渡，结构简单；此外，利用镜筒3与固定筒10之间的螺纹，可以直接将镜筒3的转动转化为镜筒3与固定筒10的纵向相对移动，可靠性高。
在一种实现方式中，镜筒3套设在固定筒10内，镜筒3的外周面上设置有外螺纹，固定筒10的内周面上设有与外螺纹相配合的内螺纹。当镜筒3转动时，即可带动镜筒3直线移动。在其他实现方式中，也可以是，固定筒10套设在镜筒3内，固定筒10的外周面上设置有外螺纹，镜筒3的内周面上设有与外螺纹相配合的内螺纹。
在一种实现方式中，第一支架1上设置有显示屏幕，镜筒3上设置有透镜32。固定筒10与镜筒3轴向相对移动时，可以改变显示屏与透镜32之间的距离，从而适用不同使用者的需求。在其他实现方式中，也可以是，第一支架1的固定筒10上设置有透镜，镜筒3上设置有显示屏幕。
在一种实现方式中，在镜筒3的远离第一支架1的一端沿周向设置近视刻度标注，并在第二支架上设置标识点，以方便用户根据自身近视程度快速调整物距，方便使用。在其他实现方式中，也可以是，在第二支架2上环镜筒3设置近视刻度标注，并在镜筒3的远离第一支架1的一端设置标识点。
在一种实现方式中，第二支架2可以设置在第一支架1与镜筒齿轮31之间且与镜筒齿轮31相贴合。在第一支架1与第二支架2之间设置有多个弹簧5。例如，多个弹簧5环绕排布在两个镜筒3整体的四周。弹簧5的轴向平行于镜筒3的轴向，弹簧5的两端分别连接于第一支架1与第二支 架2。这样，当镜筒3转动时，镜筒3通过弹簧5带动第二支架2与第一支架1沿轴向相对直线移动。在一种实现方式中，弹簧5为压簧，压缩设置在第一支架1与第二支架2之间。利用弹簧5可以在第一支架1与第二支架2的边角处提供作用力，以使得第一支架1与第二支架2能够平衡移动，避免在边角处卡死影响两个镜筒3与两个固定筒10的相对移动。在其他实现方式中，弹簧5还可以为拉簧，拉簧的两端分别与第一支架1与第二支架2连接，以提供第一支架1与第二支架2之间相互的作用力。
在一种实现方式中，弹簧5为四个，呈矩阵状排布在第一支架1与第二支架2的四个边角处。两个镜筒3位于四个弹簧5形成的矩形区域中。利用四个弹簧5可以有效保证第一支架1与第二支架2相对移动的平衡性，避免第一支架1与第二支架2在四个边角处卡死。
在一种实现方式中，第一支架1上设置有多个定位柱11，定位柱11固定于第一支架1上朝向第二支架2的一侧，定位柱11与弹簧5一一对应，弹簧5套设在定位柱11上。例如，所述定位柱11的长度可以小于或等于镜筒3位于最接近第一支架1处时第一支架和第二支架之间的最短距离。利用定位柱11可以避免弹簧5在形变过程中发生折弯影响对第一支架1与第二支架2的作用力。
在一种实现方式中，第二支架2上设置有导向杆21，导向杆21与定位柱11同轴设置。例如，定位柱11的轴向设置有导向孔110，导向杆21滑动穿设在导向孔110中。例如，导向孔110可以沿定位柱11的轴线设置。所述导向杆21的长度小于或等于镜筒3位于最接近第一支架1处时第一支架和第二支架之间的最短距离。利用导向杆21与导向孔110的配合，可以保证第一支架1与第二支架2相对移动的稳定性。
在一种实现方式中，第一支架1上设置有挂勾12，挂勾12与弹簧5勾挂连接。利用挂勾12可以方便弹簧5与第一支架1之间的装配连接，并 使得弹簧5的一端定位在定位柱11的根部处，避免脱落。
上述任一实现方式中的眼镜均可以为虚拟现实眼镜。该虚拟现实眼镜还可以包括控制系统、头戴机构等部件。
本申请提供的虚拟现实眼镜及其调节机构，当需要调节物距配合不同用户的近视度数时，用户可以转动任意一个镜筒3，从而在镜筒3转动时，通过镜筒3外围的镜筒齿轮31与同步齿轮4的啮合，使镜筒3的转动传递到另外一个镜筒上。当两个镜筒3同步转动时，镜筒3与固定筒10之间的螺纹配合可以使得镜筒3与第一支架1沿轴向相对移动，改变镜筒3上的透镜和第一支架1上的显示屏幕之间的距离，实现物距调节，使用户可以看到清晰的图像。使用一个同步齿轮4即可使得两个镜筒3同时转动，实现左右眼同步。运用齿轮系统同步加螺纹系统化转动为纵向进给，实现单屏虚拟现实眼镜的物距调节，不需要锥齿转化，也不需要多级过渡，产品结构简单，可靠性高。通过镜筒3上的近视刻度标注，可以方便用户快速调整物距。
本申请一实施例还提供了一种眼镜，包括调节机构。该调节机构可以对眼镜的瞳距及物距进行调整。
参见图4和图5，眼镜的调节机构包括两个并排设置的镜筒组件5、6，及瞳距调节组件7。两个镜筒组件5、6的结构相同，分别对应使用者的左右眼。
镜筒组件5包括第一支架511,固定连接于第一支架511上的固定筒521，以及与固定筒521同轴套设且螺纹连接的镜筒522。镜筒组件5还包括第二支架512，其中第二支架512与第一支架511沿所述镜筒522的轴向排布设置，且镜筒522可绕自身轴向转动地连接于第二支架512。镜筒组件6的结构与镜筒组件5相同。镜筒组件6包括第一支架611，固定连接于第 一支架611上的固定筒621，以及与固定筒621同轴套设且螺纹连接的镜筒622。镜筒组件6还包括第二支架612，其中第二支架612与第一支架611沿所述镜筒622的轴向排布设置，且镜筒622可绕自身轴向转动地连接于第二支架612。当镜筒转动时，利用镜筒与固定筒之间的螺纹配合，可以使得镜筒与固定筒之间沿着镜筒的轴向相对移动，改变镜筒和第一支架之间的距离，实现物距调节。
本申请实施例中，两个镜筒组件5、6相互独立，可以各自调整物距。
瞳距调节组件7连接在两个镜筒组件5、6的第二支架512、522之间。利用瞳距调节组件7可以调整两个镜筒组件5、6之间的距离。两个镜筒组件5、6可以相互靠近或远离，从而实现瞳距的调节。
瞳距调节组件7包括调节转盘71及两个齿条72、73。调节转盘71可以可转动地连接在第二支架512和612上。两个齿条72、73的结构可以相同。两个齿条72、73分别固定于两个第二支架512、612上。两个齿条72、73相互平行，且长度方向平行于两个镜筒组件5、6的排布方向。调节转盘71上同轴固定有调节齿轮74。调节齿轮74位于两个齿条72、73之间且同时啮合于两个齿条72、73，以带动两个齿条72、73相对移动。调节转盘71绕自身轴向转动时，调节齿轮74转动，从而带动两个齿条72、73相对直线移动，进而利用两个第二支架之间的相对移动使得两个镜筒组件5、6相互靠近或远离，实现瞳距的调节，结构简单，便于加工制备。
在一种实现方式中，调节机构还包括瞳距滑轨8。瞳距滑轨8与齿条72、73平行设置。两个第二支架512、612均沿瞳距滑轨8的长度方向滑动设置在瞳距滑轨8上。利用瞳距滑轨8可以保证两个第二支架512、612沿直线移动，同时保证两个第二支架512、612移动的稳定性。瞳距滑轨8可以与眼镜中的固定部件例如壳体等固定连接，使得瞳距滑轨8可以固定不动，两个第二支架512、612可以相对瞳距滑轨8滑动。
在一种实现方式中，瞳距滑轨8为两个，分别设置在镜筒组件5、6的第二支架512、612的上下两侧。利用上下两个瞳距滑轨8，可以进一步保证两个镜筒组件5、6相对移动的稳定性。
在一种实现方式中，瞳距滑轨8为柱状。第二支架512、612上设置有与瞳距滑轨8相配合的瞳距滑孔，瞳距滑轨8滑动穿设在瞳距滑孔中。此处，需要说明的是，瞳距滑轨8滑动穿设在瞳距滑孔中，是指，瞳距滑轨8穿过瞳距滑孔，瞳距滑轨8的一部分设置在瞳距滑孔中，并且瞳距滑轨8与瞳距滑孔的孔壁之间存在一定间隙，使得瞳距滑轨8与瞳距滑孔二者能够在轴向上进行相对移动。利用瞳距滑孔与瞳距滑轨8的配合，可以实现对第二支架512、612移动的导向作用，保证第二支架512、612相对移动的稳定性。此处，在其他实现方式中，也可以是，瞳距滑轨8上设置T型槽或燕尾槽，第二支架512、612上设置有T型块或燕尾块，T型块或燕尾块滑动设置在T型槽或燕尾槽中，利用T型槽或燕尾槽与T型块或燕尾块的配合保证第二支架512、612相对移动的稳定性。或者，瞳距滑轨8上设置T型块或燕尾块，第二支架512、612上设置T型槽或燕尾槽，T型块或燕尾块滑动设置在T型槽或燕尾槽中，利用T型槽或燕尾槽与T型块或燕尾块的配合保证第二支架512、612相对移动的稳定性。
齿条72具有相对的第一端72a和第二端72b。第一端72a与镜筒组件6的第二支架612固定连接，第二端72b朝向镜筒组件5的第二支架512延伸。齿条73同样具有相对的第一端和第二端，其中第一端与镜筒组件5的第二支架512固定连接，第二端朝向镜筒组件6的第二支架612延伸。在一种实现方式中，齿条72的第一端72a朝另一齿条73延伸形成有限位部721；当两齿条72、73相互靠近移动使得齿条73的第二端抵靠于齿条72的限位部721时，两个镜筒组件5、6间隙配合。也就是说，当齿条73的第二端与齿条72的限位部721相抵接时，两个镜筒组件5、6之间依然 可以保持一定间距。利用限位部721可以限制两个镜筒组件5、6相互移动的最小距离，避免两个镜筒组件5、6碰撞影响内部结构的可靠性。在其他实现方式中，也可以是齿条73的第一端朝另一齿条72延伸形成限位部731，或者是两个齿条72、73的第一端同时朝彼此形成限位部，如图5所示。
齿条73固定于镜筒组件5的第二支架512上，齿条72固定于镜筒组件6的第二支架612上。瞳距调节组件7可以通过调节两个第二支架512、612之间的距离来调节两个镜筒组件5、6之间的距离。
镜筒522可绕自身轴向转动地连接于第二支架512，固定筒521固定连接于第一支架511，镜筒522与固定筒521同轴套设且螺纹连接。当镜筒522相对第一支架511转动时，利用镜筒522与固定筒521之间的螺纹可以将镜筒522的转动转换为镜筒522与固定筒521的轴向相对直线移动。
在一种实现方式中，镜筒522套设在固定筒521内，镜筒522的外周面上设置有外螺纹，固定筒521的内周面上设有与外螺纹相配合的内螺纹。此处，在其他实现方式中，也可以是，固定筒521套设在镜筒522内，固定筒521的外周面上设置有外螺纹，镜筒522的内周面上设有与外螺纹相配合的内螺纹。
在一种实现方式中，第二支架512与第一支架511之间设置有用于使二者沿镜筒522的轴向相对直线移动的物距导向机构53。利用物距导向机构53可以保证镜筒522与固定筒521相对移动的稳定性，同时可以对固定筒521的轴向进行限位，避免固定筒521在镜筒522的带动下转动。
在一种实现方式中，物距导向机构53包括物距滑轨531及导向筒532，物距滑轨531滑动穿设在导向筒532中，物距滑轨531及导向筒532同轴设置且轴向平行于镜筒522的轴向。物距滑轨531固定于第二支架512，导向筒532固定于第一支架511。利用物距滑轨531与导向筒532的配合，可以实现对第一支架511与第二支架512之间相对移动的导向作用，保证 二者之间相对移动的平稳性。此处，在其他实施方式中，也可以是，物距滑轨531固定于第一支架511，导向筒532固定于第二支架512；或者，采用其他的物距导向机构53，例如，利用导柱与导孔的配合，滑轨与滑块的配合，等等。
在一种实现方式中，第二支架512与第一支架511之间设置有用于防止镜筒522与所述固定筒521相互分离的限位机构54。利用限位机构54可以避免第二支架512与第一支架511之间相互移动距离过大导致镜筒522与固定筒521相互分离。在一种实现方式中，限位机构54包括限位柱541及限位筒542，限位柱541与限位筒542同轴设置且平行于镜筒522的轴向。限位柱541固定于第一支架511，限位筒542固定于第二支架512。限位柱541的一端滑动设置在限位筒542中且设置有勾部(图中未示出)，限位筒542内设置有限位部(图中未示出)，限位部挡在勾部靠近第一支架511的一侧处。当第二支架512与第一支架511相互远离移动至一定距离时，勾部抵靠于限位部，从而防止限位柱541的一端从限位筒542中脱出，避免二者相互分离，进而避免镜筒522与固定筒521相互分离。此处，在其他实施方式中，也可以采用其他限位机构54对第二支架512与第一支架511之间的最大距离进行限位，例如，限位机构54可以为在物距滑轨531上远离第二支架512的一端周面上设置的凸台，当第二支架512与第一支架511相互远离移动时，凸台抵靠于导向筒532，从而避免物距滑轨531从导向筒532中脱出，进而避免镜筒522与固定筒521相互分离。
在一种实现方式中，固定筒521上设置有显示屏幕(图中未示出)，镜筒522上设置有透镜55。固定筒521与镜筒522轴向相对移动时，可以改变显示屏与透镜55之间的距离，从而适用不同使用者的需求。此处，在其他实现方式中，也可以是，固定筒521上设置有透镜，镜筒522上设置有显示屏幕。
在一种实现方式中，镜筒522上的远离第一支架511的一端沿自身周向设置有近视刻度标注56，并在第二支架512上设置标识点，以方便用户根据自身近视程度快速调整物距，方便使用。或者，也可以是，在第二支架512上环镜筒522设置近视刻度标注，并在镜筒522的远离第一支架511的一端设置标识点。
上述仅针对镜筒组件5对镜筒组件的结构进行了描述，镜筒组件6的结构可参照上述镜筒组件5的描述。
上述任一实现方式中的眼镜均可以为虚拟现实眼镜。该虚拟现实眼镜还可以包括控制系统、头戴机构等部件。
本申请实施例提供的虚拟现实眼镜及其调节机构，采用了双屏幕设计，两个镜筒组件上分别设置有独立的屏幕，同时和透镜组合实现光学功能。两个镜筒组件之间通过齿轮齿条设计来实现在滑轨上的远离和靠拢，以得到双眼瞳距调节的功能。镜筒与固定筒螺纹套设在一起，当拧动镜筒时，镜筒旋转，通过螺纹将镜筒的转动变成镜筒和固定筒的纵向相对运动，以改变透镜和屏幕之间的距离，实现物距调节。由于为双屏结构，左右镜筒组件可实现独立物距调节功能。
在一种实现方式中，还可以将上述瞳距调节组件设置在镜筒组件5、6的第一支架上，在这种情况下，可以省去镜筒组件5、6的第二支架，并将瞳距滑轨设置在两个第一支架上，从而使镜筒522、622相对第一支架沿镜筒轴向移动。本申请一实施例还提供了一种眼镜的调节机构，包括两个并排设置的镜筒组件、及瞳距调节组件。每个所述镜筒组件包括：第一支架，固定连接于所述第一支架上的固定筒，与所述固定筒同轴套设且螺纹连接的镜筒。所述瞳距调节组件包括：两个长度方向平行于所述两个镜筒组件的排布方向的齿条，其中，所述两个齿条分别固定于所述两个镜筒组件的第一支架上；以及位于所述两个齿条之间且同时啮合于所述两个齿条 的调节齿轮。在一种实现方式中，所述调节齿轮可以通过调节转盘转动设置在两个第一支架上。
