为了解决有的头戴式虚拟现实设备瞳距调节机构零部件多，结构复杂的问题，本发明提供了一种头戴式虚拟现实设备瞳距调节机构，如图1和图2所示，包括：
传动轮1，所述传动轮1上设有螺旋槽11。螺旋槽11的形状可选地为螺旋线形状。
连接支架1，所述连接支架1的一端与所述螺旋槽11滑动配合。可选地，连接支架1与螺旋槽11之间的滑动配合可通过在连接支架1的端部上设置与螺旋槽11相配合的卡爪实现，或者通过在连接支架1的端部上设置与螺旋槽11相配合的柱状凸起实现。当然，其它可实现连接支架1与螺旋 槽11滑动配合的结构均可应用于本发明。
镜筒支架3，所述镜筒支架3与所述连接支架2的另一端固定连接。镜筒支架3与连接支架20之间的固定连接可通过焊接，或者一体成型，或者螺栓连接等方式实现。
使用时，转动传动轮1，连接支架2的一端沿着螺旋槽11移动，此时与连接支架2的另一端固定连接的镜筒支架3随之移动，从而实现瞳距调节的目的。此外，通过螺旋槽11调节瞳距可实现对瞳距在可选距离范围内的调整，从而有利于实现瞳距微调。
本发明的头戴式虚拟现实设备瞳距调节机构的传动轮1转动后由连接支架2带动镜筒支架3移动，实现瞳距的调节，结构简单，零部件少。
在本发明头戴式虚拟现实设备瞳距调节机构的一个具体实施例中，所述连接支架2上设有与所述螺旋槽11滑动配合的上滑动柱(图中未示出)。上述上滑动柱可选地位于连接支架2邻近传动轮1的一侧。
当所述传动轮1转动时，所述上滑动柱沿着所述螺旋槽11滑动。
在本发明头戴式知能设备瞳距调节机构的另一个具体实施例中，还包括底盖4。底盖4可选地具有板状结构。
所述底盖4上设有传动轮定位部41。传动轮定位部41可通过固定连接与底盖4连接在一起。上述固定连接例如为一体成型，或者焊接等。
传动轮定位部41可选地具有圆柱形槽或凸起的结构。
所述传动轮1固定在所述传动轮定位部41上，且所述传动轮1绕所述传动轮定位部41转动。传动轮1与传动轮定位部41之间的固定可通过螺栓连接，或者齿轮传动的方式实现。以传动轮1与传动轮定位部41螺栓连接为例，螺栓自传动轮定位部41上的安装孔中穿过，并与传动轮1螺纹连接在一起。传动轮1以螺栓为轴实现旋转。
可选地，所述底盖4上设有限位槽(图中未示出)。限位槽可为直接开设在底盖4上的槽状结构，或者，限位槽为开设在底盖4的表面上设置的限位凸起42上的槽状结构。
所述镜筒支架3上设有限位部31。
所述限位部31与所述限位槽相配合，以限制所述镜筒支架3的移动。 限位部31可为镜筒支架3上的凸起。当限位槽为限位凸起42上的槽状结构时，限位槽可选地位于限位凸起42朝向限位部31的一侧上。
限位槽的设置可对镜筒支架3的移动方向和/或移动位移进行限制。本领域技术人员可根据需求设置限位槽的朝向。例如，限位槽沿着水平方向延伸，使得镜筒支架3沿着水平方向移动。
可选地，本发明头戴式虚拟现实设备瞳距调节机构还包括导向组件。
所述导向组件包括滑杆5、底盖座43和镜筒支架座32。
所述底盖座43与所述底盖4固定连接，所述镜筒支架座32与所述镜筒支架3固定连接。上述固定连接可通过焊接或一体成型的方式实现。
所述滑杆5与所述底盖座43和所述镜筒支架座32相配合，以使得所述传动轮1转动时所述镜筒支架3沿着所述滑杆5移动。滑杆5可选地自底盖座43和镜筒支架座32中穿过。此外，滑杆5与底盖座43和镜筒支架座32之间的配合可选地为间隙配合，以使得镜筒支架32可轻松地沿着滑杆5移动。
当传动轮1带动镜筒支架3移动时，镜筒支架3沿着滑杆5移动。滑杆5的朝向可根据实际需求设置，例如，滑杆5沿着水平方向延伸。
在本发明头戴式虚拟现实设备瞳距调节机构的又一个具体实施例中，还包括上盖6，所述上盖6上设有限位孔61。限位孔61的形状可根据需求设置，例如，限位孔61为圆形孔，或者限位孔61为腰形孔。
所述连接支架2邻近所述上盖6的表面上设有下滑动柱221。
所述下滑动柱221位于所述限位孔61中，以限制所述镜筒支架3的移动。下滑动柱221位于限位孔61中，使得镜筒支架3的移动受到限位孔61的形状和尺寸的限制。限位孔61可选地沿着水平方向延伸，以限制镜筒支架3水平方向的移动。
当传动轮1转动后带动连接支架2移动进而带动镜筒支架3移动时，下滑动柱221与限位孔61的边缘相抵时即为镜筒支架3的极限位移位置。
当头戴式虚拟现实设备瞳距调节机构同时具有底盖4和上盖6时，底盖4和上盖6还可通过螺杆等结构相对固定在一起，以增大头戴式虚拟现实设备瞳距调节机构的强度。
本发明头戴式虚拟现实设备瞳距调节机构的传动轮1数量可根据实际需求设置，例如，传动轮1为一个或者两个。
当传动轮1为一个时，转动传动轮1同时调节头戴式智能设备左右眼瞳距，也即是左右眼瞳距同步调节。当传动轮1为两个时，可分别对左右眼瞳距进行调节。
可选地，所述连接支架2可选地包括左连接支架和右连接支架。
所述镜筒支架3包括分别与所述左连接支架和所述右连接支架固定连接的左镜筒支架和右镜筒支架。
所述左连接支架和所述右连接支架与单一的传动轮1的螺旋槽11滑动配合。单一的传动轮1有利于防止左右眼瞳距调节出现差异，防止左右眼瞳距失衡。
当转动单一的传动轮1时，与螺旋槽11滑动配合的左连接支架和右连接支架均沿着螺旋槽11移动，此时分别与左连接支架和右连接支架固定连接的左镜筒支架和右镜筒支架随着传动轮1的转动而同步移动，从而实现左右眼瞳距同步调节。此时转动传动轮1可同时调节左右眼的瞳距，使用方便。
当然，本领域技术人员也可想到，当传动轮1为两个时，左连接支架和右连接支架分别与两个传动轮1中的一个相配合，从而转动不同的传动轮1可对与左连接支架和右连接支架固定连接的左镜筒支架和右镜筒支架分别移动，从而实现左右眼瞳距独立调节。
可选地，所述左连接支架和所述右连接支架镜像对称。
连接支架2的结构可选地包括支架座21和支架杆22。支架座21可选地为矩形块形状。支架杆可选地具有板状结构。
所述支架座21与所述镜筒支架3固定连接。上述固定连接可通过焊接或螺栓连接等方式实现。
所述支架杆22的一端与所述支架座21固定连接，所述支架杆22的另一端与所述螺旋槽11滑动配合。支架杆22与支座座21之间的固定连接可通过安装槽和支架杆22的一端相配合的结构实现，或者，通过卡扣连接等方式实现。
本发明头戴式虚拟现实设备瞳距调节机构的具体实施例中，包括传动轮1、连接支架2、镜筒支架3、底盖4、滑杆5和上盖6。传动轮1的数量为一个，其上设有螺旋槽11。传动轮1通过传动轮定位部41固定在底盖4上。连接支架2包括镜像对称的左连接支架和右连接支架，左连接支架和右连接支架均包括支架座21和支架杆21。支架杆21上设有与螺旋槽11滑动配合的上滑动柱和与上盖6上的限位孔61相配合的下滑动柱221，限位孔61沿水平方向延伸。镜筒支架3包括左镜筒支架和右镜筒支架。左镜筒支架和右镜筒支架上均设有限位部31，限位部31与底盖4上的限位凸起42上的限位槽相配合，限位槽沿水平方向延伸。滑杆5分别自镜筒支架3的镜筒支架座32和底盖4的底盖座43中穿过，滑动5沿水平方向延伸。使用时，转动传动轮1，上滑动柱沿着螺旋槽11移动，此时与连接支架2固定连接的镜筒支架3随之移动，从而实现瞳距调节的目的。在该实施例中，左右眼瞳距同步调节。
本发明还提供了一种头戴式虚拟现实设备，包括本发明的头戴式虚拟现实设备瞳距调节机构。
本发明的头戴式虚拟现实设备可为VR头罩、VR头盔、VR眼镜等。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
