下面详细描述本申请的实施例，实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考附图描述根据本申请实施例的头戴式电子设备1。
如图1-图7所示，根据本申请实施例的头戴式电子设备1包括外壳100、获取单元200、左显示单元301、右显示单元302和驱动装置400。
外壳100内设有控制器，获取单元200设置于外壳100并与外壳100内的控制器相连，获取单元200能够获取人眼位置并将获取到关于人眼的信息传送给控制器。
左显示单元301和右显示单元302中的每个显示单元均包括镜片320和支撑件310，镜片320固定至支撑件310上，驱动装置400包括驱动件410和两个移动件420，驱动件410与两个移动件420配合以驱动两个移动件420移动，驱动件410能够带动两个移动件420背向移动或相向移动，以调节两个移动件420之间的距离。两个移动件420 分别与两个支撑件310配合以在两个移动件420背向移动或相向移动时，能够带动两个支撑件310背向移动或相向移动，以带动左显示单元301和右显示单元302相向移动或背向移动，以调节左显示单元301和右显示单元302之间的距离。
具体而言，驱动件410与控制器相连，控制器根据获取单元200获取的信息控制驱动件410驱动两个移动件420移动，两个移动件420通过带动支撑件310可带动镜片320相向移动或背向移动，以根据获取单元200获取到的人眼位置调整两个镜片320之间的距离，使用户在使用头戴式电子设备1时，两个镜片320之间的距离可以根据用户的人眼位置自动调节，提高用户的使用体验。
在一些实施例中，头戴式电子设备1能够生成模拟环境，用户可通过镜片320观测头戴式电子设备1所生成的模拟环境。外壳100上设置有两个获取单元200，以分别获取用户两个眼睛的位置。两个获取单元200将其获取的位置传送给控制器，控制器可以根据两个获取单元200传送的信息计算出用户两眼瞳孔之间的距离也就是瞳距，控制器根据瞳距控制驱动件410驱动移动件420进行移动，移动件420通过支撑件310带动两个镜片320背向移动或相向移动，以调节两个镜片320之间的距离，使两个镜片320之间的距离与控制器计算出的瞳距相适配，便于用户更清晰的观察头戴式电子设备1生成的模拟环境。
因此，根据本申请实施例的头戴式电子设备1可根据用户瞳距自动调节两个镜片320的距离、提高用户体验。
下面参考附图描述根据本申请具体实施例的头戴式电子设备1。
在本申请的一些具体实施例中，如图1-图7所示，根据本申请实施例的头戴式电子设备1包括外壳100、获取单元200、左显示单元301、右显示单元302和驱动装置400。
根据本申请的一些实施例，获取单元200为摄像头，以对人眼进行拍摄，得到人眼的位置。
其中，摄像机可多次拍摄人眼的位置，以准确的获取人眼的信息，将正确的人眼位置传送给控制器。
在一些实施例中，如图2、图3所示，为了准确的拍摄人眼的位置，外壳100在其长度方向上的两侧各设有一个摄像机。在用户佩戴好头戴式电子设备1时，获取单元200位于人眼的下方位置，设置在人眼的外侧，以清楚的对人眼进行拍摄，为控制器提供人眼的位置信息。
根据本申请的一些实施例，移动件420和支撑件310可拆卸配合，便于用户对移动 件420和支撑件310的相对位置进行调整。在本申请的一些示例中，移动件420和支撑件310之间通过螺钉可拆卸配合。
具体而言，镜片320固定在支撑件310上，移动件420与支撑件310的可拆卸配合便于用户对移动件420和支撑件310的相对位置进行调节，以对移动件420和镜片320的相对位置进行调整，使两个移动件420都能准确的控制对应镜片320的移动，以在驱动件410驱动两个移动件420进行移动时，两个移动件420能够更准确控制两个镜片320的背向移动或相向移动，以精确的调整两个镜片320之间的距离。
此外，移动件420和支撑件310的可拆卸配合还便于用户将支撑件310和镜片320从外壳100上取下，便于用户对镜片320进行清洗或更换。
根据本申请的一些实施例，显示单元还包括镜筒330和屏幕340，每个镜片320设置在镜筒330上，镜筒330固定在所述支撑件310上，每个镜筒330和相应的支撑件310之间设有屏幕340，镜筒330能够对镜片320和对应的屏幕340进行支撑，以对屏幕340的位置进行限定，便于用户通过镜片320观看屏幕340上的内容。
其中屏幕340可以是LCD、OLED、MiniLED，MicroLED等显示屏。
具体而言，镜片320固定在镜筒330的一端，屏幕340固定在镜筒330的另一端以与镜片320之间具有一定的距离，支撑件310固定在镜筒330的另一端。当驱动件410驱动移动件420移动时，移动件420通过支撑件310带动屏幕340、镜筒330和镜片320进行移动，使两个镜筒330、两个镜片320、两个屏幕340相向或背向移动。
在一些实施例中，镜筒330形成为圆柱体，镜片320朝向镜筒330的投影为圆形，以将镜片320安装在镜筒330的一端，用户可通过镜片320观看镜筒330内屏幕340上的内容。
屏幕340安装在镜筒330的另一端，屏幕340用于显示内容的区域可形成为圆形，与镜筒330相适配，便于用户通过镜片320观看屏幕340上的全部内容。
此外，镜筒330可以设置为可伸缩的镜筒330，能够调节镜片320与屏幕340之间的距离，以调节人眼与屏幕340之间的距离，这样近视和远视的用户就都能清晰的观看到屏幕340上的内容。根据本申请的一些实施例,头戴式电子设备1还包括限位装置700，限位装置700分别与移动件420和外壳100配合以限制移动件420的移动范围,以保证驱动件410能够顺畅的驱动移动件420背向移动或相向移动时，同时避免两个移动件420之间的距离过大或过小，影响用户的使用。
根据本申请的一些实施例，驱动件410为驱动电机，驱动装置400还包括丝杠430，驱动电机与丝杠430配合以驱动丝杠430转动，丝杠430设有双旋向外螺纹，两个移 动件420分别与丝杠430螺纹配合，头戴式电子设备1还设置了用于限制移动件420的转动自由度的限制件，避免两个移动件420随丝杠430发生转动，以在丝杠430转动时可带动两个移动件420的移动。
在一些实施例中，如图5、图6所示，这两个移动件420分别为第一移动件421和第二移动件422，丝杠430的上设置有两段螺纹，位于丝杠430上的不同侧，分别为左旋外螺纹和右旋外螺纹，第一移动件421上设置有左旋内螺纹，以与丝杠430上的左旋外螺纹配合。第二移动件422上设置有右旋内螺纹，以与丝杠430上的右旋外螺纹配合。
当丝杠430顺时针转动时，第一移动件421和第二移动件422相向移动，此时两个支撑件310相向移动以将两个镜片320之间的距离调近。当丝杠430逆时针转动时，第一移动件421和第二移动件422背向移动，此时两个支撑件310背向移动以将两个镜片320之间的距离调远。
根据本申请的一些可选实施例，驱动电机的旋转轴线与丝杠430的旋转轴线重合，以保证驱动电机转动时可驱动丝杠430沿相同的方向进行转动，进一步保证驱动电机转动时可驱动两个移动件420相向移动或背向移动，同时可以节省空间。
进一步地，驱动电机直接与丝杠430连接以驱动丝杆430转动，从而该驱动方式简单，节省空间且可以降低头戴式电子设备1的重量。
根据本申请的一些可选实施例，头戴式电子设备1还包括固定件600，固定件600固定至外壳100，驱动件410固定在固定件600上，以通过驱动件410驱动移动件420相对于外壳100进行移动。
具体而言，用户在使用头戴式电子设备1时，人眼的位置相对于外壳100并不发生移动，即相对于固定件600和驱动件410不发生移动，当驱动件410驱动移动件420移动时，移动件420带动支撑件310和镜片320相对于驱动件410发生移动，即相对于固定件600、外壳100和人眼发生移动。在镜片320相向或背向移动时，镜片320相对于人眼的位置发生移动，以适应用户的人眼位置，使两个镜片320之间的距离与人眼之间的距离相适配。
根据本申请的一些具体实施例，限制件包括导引轴510，导引轴510固定在固定件600上，每个支撑件310上设有配合孔311，导引轴510穿过配合孔311且配合孔311与导引轴510移动配合，也就是导引轴510穿过支撑件310上的配合孔311将支撑件310与固定件600配合起来，以避免支撑件310发生转动。
具体而言，支撑件310与移动件420相固定，导引轴510在限制支撑件310转动的 同时也限制了移动件420的转动。也就是说，当驱动件410驱动丝杠430转动时，能够避免移动件420随丝杠430一起发生转动，以将丝杠430的转动转化为移动件420的移动，通过移动件420带动支撑件310和镜片320进行移动。
在一些实施例中，如图5所示，固定件600上设置有两个导引轴510，这两个导引轴510沿左右方向设置在固定件600上，两个导引轴510的轴向在一条直线上，沿左右方向延伸。两个支撑件310沿左右方向间隔设置，每个支撑件310朝向固定件600的一侧设置有多个配合孔311，以使每个支撑件310与对应的导引轴510更稳定的相配合。
当支撑件310随移动件420移动时，配合孔311在导引轴510上沿左右方向进行移动，以限制支撑件310只能沿左右方向进行移动，例如，左侧的支撑件310带动对应的镜片320朝右移动，右侧的支撑件310带动对应的镜片320朝左移动，此时两个镜片320之间的距离变近；左侧的支撑件310带动对应的镜片320朝左移动，右侧的支撑件310带动对应的镜片320朝右移动，此时两个镜片320之间的距离变远(左右方向如图5所示，这里需要理解的是，上述方向限定仅为便于对附图进行描述，不会对头戴式电子设备1的实际设置位置和方向产生限定)。
通过限制支撑件310沿左右方向移动，以调节两个镜片320之间沿左右方向的距离，使两个镜片320之间的距离能够适配于用户的瞳距，便于用户更清晰的观看屏幕340上的内容。
根据本申请的一些具体实施例，头戴式电子设备1还包括限位装置700，限位装置700包括设在固定件600上的避让通道720和设在支撑件310上的配合凸起710，配合孔311设在配合凸起710内，配合凸起710与避让通道720移动配合，避让通道720的长度限定配合凸起710的移动范围以限定移动件320的移动范围，避免移动件320移动的范围过大，避免两个移动件320之间的距离过大或过小。
具体而言，通过设置避让通道720能够限制移动件320的移动范围，进而对支撑件310的可移动范围进行限制，避免移动件320相向或背向移动的距离过大，避免两个支撑件310之间的距离过大，影响后续对两个镜片320之间距离的调节；避免两个支撑件310之间的距离过小而导致左显示单元301和右显示单元302发生碰撞，对左显示单元301和右显示单元302造成剐蹭等损害。
在一些实施例中，如图6、7所示，固定件600的左右两侧设有两个避让通道720，分别与两个支撑件310上的配合凸起710相对应，避让通道720的长度方向沿左右方向延伸，配合凸起710的至少一部分设置在避让通道720内与避让通道720滑动配合， 当驱动件410带动移动件420背向移动时，左侧的配合凸起710向左移动，并至多可移动至对应避让通道720的最左端，右侧的配合凸起710向右移动，并至多可移动至对应避让通道720的最右端，此时两个镜片320之间的距离为最大值，移动件420无法继续带动两个镜片320继续背向移动。
当驱动件410带动移动件420相向移动时，左侧的配合凸起710向右移动，并至多可移动至对应避让通道720的最右端，右侧的配合凸起710向左移动，并至多可移动至对应避让通道720的最左端，此时两个镜片320之间的距离为最小值，移动件420无法继续带动两个镜片320继续相向移动。
根据本申请的一些可选实施例，固定件600上设有移动通道610，限制件包括设在支撑件310上的滑动凸起520，滑动凸起520与移动通道610的内壁移动配合，以通过限制滑动凸起520的移动限制支撑件310的移动方向。
具体而言，支撑件310上的滑动凸起520与固定件600上移动通道610相配合，当滑动凸起520在移动通道610内发生移动时，支撑件310相对于固定件600沿移动通道610发生移动。
在一些实施例中，如图5、图7所示，移动通道610的长度方向沿左右方向延伸，固定件600上设置有两个移动通道610，这两个移动通道610沿左右方向间隔设置，每个移动通道610与一个支撑件310上的滑动凸起520相配合。当驱动件410驱动移动件420沿左右方向移动时，移动件420可带动支撑件310上的滑动凸起520在移动通道610内沿左右方向发生移动，以改变两个支撑件310之间的距离，进而改变两个镜片320之间的距离。
根据本申请的一些具体实施例，支撑件310上设有卡扣件312，卡扣件312伸出移动通道610后钩挂至固定件600的壁面上，以使支撑件310可以稳定的相对于固定件600发生移动，避免支撑件310与固定件600发生脱落。
具体而言，卡扣件312钩挂在固定件600的壁面上，能够使支撑件310和固定件600更稳定的配合，当支撑件310发生移动时，卡扣件312可在移动通道610内发生移动，并与支撑件310的移动方向一致，避免影响支撑件310与镜片320的移动。根据本申请的一些实施例，驱动装置400还包括减速器，减速器的输入端与驱动电机相连，减速器的输出端与丝杠430相连，通过减速器能够调节丝杠430的转动速度，以调节移动件420的移动速度，调节支撑件310和镜片320的移动速度。
具体而言，减速器可以为齿轮减速器或蜗轮蜗杆减速器，以调节驱动电机输出至丝杠430上的转速，调节两个移动件420相向移动或背向移动的移动速度，避免移动件 420带动支撑件310和镜片320移动的过快或过慢，影响调节两镜片320之间距离时的调节的精度。
需要进行说明的是，驱动装置400的结构不限于此，只要可以驱动两个支撑件310移动即可，例如驱动装置400可以包括齿轮组和与齿轮组啮合的齿条，每个移动件420设有齿条，通过驱动齿条移动以带动移动件420移动。
