图1为本发明实施例的增强现实设备的分解结构示意图，图2为本发明实施例的调节组件的结构示意图，图3为本发明实施例的调节组件及光机的安装结构示意图，如图1至3所示。
本发明实施例提供了一种增强现实设备，包括：光机10、调节组件20及壳体30。其中，
调节组件20设置在壳体30内，其中，调节组件20包括依次首尾相连的旋转组件21、摆动组件22及平移组件23。
光机10的部分伸入壳体30，并与调节组件20连接，光机10通过旋转 组件21、摆动组件22及平移组件23可分别实现相对壳体30的旋转、摆动及平移。
壳体30在光机10的摆动方向上设置有开口31。
举例来说，进行光机10旋转调整时，可将摆动组件22和平移组件23与壳体30当做整体看待，用户可旋转光机10，在旋转组件21的作用下，光机10可实现旋转以改变光机10的投射角度，此时摆动组件22和平移组件23不做调整。进行光机10摆动调整时，可将光机10与旋转组件21当做整体看待，平移组件23与壳体30当做整体看待，用户可摆动光机10，在摆动组件22的作用下，光机10可实现摆动以改变光机10与使用者眼睛之间的距离，也可理解为光机10的物距调节，此时旋转组件21和平移组件23不做调整。进行光机10平移调整时，可将光机10、旋转组件21及摆动组件22当做整体看待，用户可平移光机10，在平移组件23的作用下，光机10可实现平移以改变光机10与使用者瞳孔之间的距离，也可理解为光机10的瞳距调节，此时旋转组件21和摆动组件22不做调整。
本发明实施例提供的技术方案，设置与光机10连接的调节组件20，可实现光机10的三自由度的调整。例如，通过旋转组件21可实现光机10的转动调节，以调整光机10的投射角度。通过摆动组件22可实现光机10的摆动调节，以调整光机10与使用者眼睛之间的距离。通过平移组件23可实现光机10的平移调节，以调整光机10与使用者瞳孔之间的距离。通过调节组件20可简单方便地将光机10调节至合适的佩戴位置，以适应不同用户的佩戴需求。
下面对本发明实施例提供的增强现实设备做进一步的详细介绍。
本发明实施例中的旋转组件21的实现方式包括多种，一种可实现的方式是，参见图4和图5，旋转组件21包括固定盘211、紧固螺丝212及弹片组213。固定盘211与光机10连接，弹片组213设置在固定盘211与摆动组件22之间，紧固螺丝212穿过固定盘211及弹片组213与摆动组件22连接，固定盘211与摆动组件22对弹片组213形成挤压。
具体地，固定盘211与光机10之间可通过螺丝进行固定连接，固定盘211及弹片组213上设置有相互贯通的通孔。紧固螺丝212穿过通孔与摆动 组件22连接，以实现固定盘211及弹片组213的固定，通过固定盘211和摆动组件22实现对弹片组213的挤压。固定盘211以紧固螺丝212为轴进行转动。通过控制固定盘211施加在弹片组213上的压力，可控制弹片组213的压缩量，以控制旋转时的阻尼里的大小。通过弹片组213的压缩获得预紧力，通过预紧力可在没有外部旋转力参与进来时，将光机10限定在当前的转动位置。
本发明实施例中，可选地，弹片组213包括两个曲面弹片，两个曲面弹片通过凸面相互连接，凹面分别朝向固定盘211及摆动组件22。固定盘211和摆动组件22对两个曲面弹片进行挤压时，两个曲面弹片的凸面相互挤压，形成预紧力。
举例来说，在进行旋转调整时，用户向光机10施加旋转力，光机10带动固定盘211以紧固螺丝212为轴转动，此时，摆动组件22和平移组件23不动。当调整完毕后，撤去旋转力，在弹片组213的作用下，光机10被限定在当前的旋转位置。
继续参见图4和图5，本发明实施例中，摆动组件22的一种可实现方式是，摆动组件22包括底盘221、带有弹簧222的摆动轴223、摆动动件224及摆动定件225。底盘221与旋转组件21可转动连接。摆动定件225与平移组件23固定连接。摆动动件224固定在底盘221上，摆动轴223依次将弹簧222、摆动定件225及摆动动件224同轴连接在底盘221上，弹簧222与底盘221对摆动定件225及摆动动件224形成挤压。
具体地，底盘221与旋转组件21中的紧固螺丝212可转动连接，通过摆动轴223依次将弹簧222、摆动定件225及摆动动件224进行同轴固定在底盘221上。同时，弹簧222持续压缩提供预紧力，通过预紧力为摆动动件224及摆动定件225的连接提供摆动阻尼，在没有外部摆动力参与进来时，将光机10限定在当前的摆动位置。
参见图5及图6，本发明实施例中，底盘221的一种可实现的方式是，底盘221包括中间板2211及设置在中间板2211相对的两侧并背向旋转组件21延伸的第一侧板2212和第二侧板2213。底盘221通过中间板2211与旋转组件21可转动连接。具体地，中间板2211与旋转组件21中的紧固螺丝 212可转动连接，中间板2211与固定盘211对弹片组213形成挤压。
摆动动件224、摆动定件225及弹簧222均位于第一侧板2212与第二侧板2213之间，摆动动件224固定在第二侧板2213上，摆动轴223依次穿过第一侧板2212、弹簧222、摆动定件225及摆动动件224与第二侧板2213固定连接。摆动动件224与第二侧板2213的固定方式，包括：第二侧板2213上设置有多个第一固定部2214，摆动动件224上设置有与多个第一固定部2214配合使用的多个第二固定部2241，摆动动件224通过多个第二固定部2241固定在多个第一固定部2214上。第一固定部2214可为凸起，第二固定部2241可为与凸起相配合的凹槽，或者第二固定部2241可为凸起，第一固定部2214可为与凸起相配合的凹槽，或者固定部为相应的凹槽和凸起的组合。
继续参见图6，为限制摆动组件22的摆动位置和幅度，本发明实施例中，摆动动件224上设置有第一限位齿2242，摆动定件225上设置有与第一限位齿2242配合使用的第二限位齿2251。一种可实现的方式是，第一限位齿2242及第二限位齿2251为相互配合使用的波浪形齿。第一限位齿2242与第二限位齿2251啮合，并限制摆动动件224相对摆动定件225的摆动位置及幅度。
举例来说，在进行摆动调整时，用户向光机10施加摆动力，光机10通过旋转组件21带动底盘221摆动，底盘221通过第一固定部2214带动摆动动件224转动，此时，摆动定件225不动。通过设定第一限位齿2242/第二限位齿2251的齿数量、齿与齿之间的间距，可限制摆动动件224相对摆动定件225的摆动幅度。当摆动完成后，撤去外部摆动力，在弹簧222与第一侧板2212、第二侧板2213对摆动动件224和摆动定件225形成挤压，使得第一限定齿与第二限定齿紧紧啮合在一起，限制当前摆动动件224相对摆动定件225的摆动位置。
参见图4、图5和图7，本发明实施例中，平移组件23的一种可实现的方式是，平移组件23包括滑动件231及限位弹片232。壳体30内设置有平移滑道32及多个限位卡口33，滑动件231与摆动组件22固定连接，滑动件231部分伸入平移滑道32内并可沿平移滑道32滑动。限位弹片232与滑 动件231固定连接，限位弹片232通过与一个限位卡口33卡合连接限制滑动件231的滑动位置。
具体地，滑动件231与摆动组件22中的摆动定件225连接，限位弹片232可通过金属材料制成，例如，限位弹片232为不锈钢材料制成。通过滑动件231沿平移滑道32内滑动，以调整光机10相对于壳体30的相对位置。通过限位弹片232的可弯曲回弹性，与多个限位卡口33中的一个卡合连接，以限定滑动件231的滑动位置。
为防止光机10在进行平移调整时，滑出壳体30，本发明实施例中，可选地，平移滑道32和/或多个限位卡口33靠近光机10的一端设置有限位部(图中未示出)。当滑动件231向外滑动，也就是沿着平移滑道32向平移滑道32靠近光机10的一端滑动时，由于有限位部的阻挡，滑动部不会滑出平移滑道32，从而防止滑动件231滑出平移滑道32，防止光机10从壳体30内脱离。
本发明实施例中，平移滑道32及限位卡口33可根据平移组件23的不同设置方式设置在不同的位置处，一种可实现的方式是，继续参见图7，壳体30的位于开口31两侧的侧壁上分别设置有平移滑道32，位于开口31同侧的侧壁上设置有多个限位卡口33。
另外，参见图1，增强现实设备还包括佩戴部40，佩戴部40与壳体30可转动连接。佩戴部40包括但不限于为镜腿，光机10可相对壳体30可转动，壳体30与镜腿可摆动，从而实现光机10的二次摆动调节，增加了光机10的调节幅度及精度。为使用不同使用者的佩戴需求，镜腿可分为多部分组成，以调节镜腿的佩戴长度。
为方便调节组件20及光机10安装在壳体30内，壳体30包括第一壳体34及第二壳体35，其中，第二壳体35罩扣在第一壳体34上，开口31、平移滑道32及限位卡口33均设置在第一壳体34上。
本发明实施例提供的技术方案，设置与光机连接的调节组件，可实现光机的三自由度的调整。例如，通过旋转组件可实现光机的转动调节，以调整光机的投射角度。通过摆动组件可实现光机的摆动调节，以调整光机与使用者眼睛之间的距离。通过平移组件可实现光机的平移调节，以调整光机与使 用者瞳孔之间的距离。通过调节组件可简单方便地将光机调节至合适的佩戴位置，以适应不同用户的佩戴需求。
需要说明的是，虽然结合附图对本发明实施例的具体实施方式进行了详细地描述，但不应理解为对本发明实施例的保护范围的限定。在权利要求书所描述的范围内，本领域技术人员不经创造性劳动即可做出的各种修改和变形仍属于本发明实施例的保护范围。
本发明实施例的示例旨在简明地说明本发明实施例的技术特点，使得本领域技术人员能够直观了解本发明实施例的技术特点，并不作为本发明实施例的不当限定。
以上所描述的装置实施例仅仅是示意性的，其中所述作为分离部件说明的单元可以是或者也可以不是物理上分开的。本领域普通技术人员在不付出创造性的劳动的情况下，即可以理解并实施。
上述说明示出并描述了本发明实施例的若干优选实施例，但如前所述，应当理解本发明实施例并非局限于本文所披露的形式，不应看作是对其他实施例的排除，而可用于各种其他组合、修改和环境，并能够在本文所述申请构想范围内，通过上述教导或相关领域的技术或知识进行改动。而本领域人员所进行的改动和变化不脱离本发明实施例的精神和范围，则都应在本发明实施例所附权利要求的保护范围内。
