具体实施方式
为了使得本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例的附图，对本申请实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本申请的一部分实施例，而不是全部的实施例。基于所描述的本申请的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本申请保护的范围。
除非另外定义，本申请使用的技术术语或者科学术语应当为本申请所属领域内具有一般技能的人士所理解的通常意义。本申请中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
为了保持本申请实施例的以下说明清楚且简明，本申请省略了已知功能和已知部件的详细说明。
如图1至图18所示，本申请实施例提供了一种用于眼镜的连接机构。眼镜可以包括容纳镜片的镜框和镜腿。连接机构包括第一部件100、第二部件200和第三部件300。第一部件100用于与镜框 连接。第二部件200通过第一转轴201转动连接于第一部件100，第二部件200能够相对第一部件100在第一方向转动。第三部件300用于与镜腿连接。第三部件通过第二转轴305转动连接于第二部件200，第三部件300能够相对第二部件200在不同于第一方向的第二方向转动。第二转轴305的轴向方向不同于第一转轴201的轴向方向。通过上述结构，能够实现镜腿在第一方向的张合和第二方向的摆动。
第一方向和第二方向均为呈弧线形的转动方向，且第一方向和第二方向呈类似于十字交叉型。第二部件200相对第一部件100的转动可以为左右的张合(即外张和合拢)，而第三部件300相对第二部件200的转动则可以为上下的摆动。可以理解的，可以定义镜框具有长度方向和宽度方向。在用户佩戴眼镜时，镜框的长度方向与用户的左右眼连线的延伸方向基本相同，镜框的宽度方向与用户的上下方向基本相同。此处的“左右”方向可以理解为镜框的长度方向，“上下”方向可以理解为镜框的宽度方向。
当本申请实施例的连接机构应用于眼镜时，能够实现镜腿在两个不同方向上的运动，即，能够使眼镜的两个镜腿能够外张(向外掰)，以适应不同佩戴者的头围，提高适配性。而且眼镜的两个镜腿还可以上下摆动，实现上下调节，以适应不同佩戴者的耳朵的高度，提升眼镜的使用性能。
可以理解的，本申请实施例中的第二部件200和第三部件300也可以独立于第一部件单独应用于眼镜，使得眼镜的镜腿的可以实现上下摆动。在该示例中，第二部件200可以通过其他的部件与镜框连接。
在一个示例中，本公开提供一种眼镜，眼镜可以包括容纳镜片的镜框、转轴(例如第二转轴)、中间连接件(例如第二部件)和镜腿。中间连接件与镜框连接，镜腿可以通过转轴与中间连接件可转动连接，该转轴的轴向方向基本沿镜框的长度方向延伸。镜腿的部件上可以设有第一齿部，中间连接件上设有与第一齿部适配的第二齿部，第一齿部和第二齿部用于当镜腿相对中间连接件转动时，第一齿部和第二齿部弹性接触且相对移动以提供转动阻尼。
可选的，结合图3-6以及图9-10，除了以第二转轴305为转轴使第三部件300与第二部件200转动连接外,还可以以第三部件300上的凸柱310(将在下文具体介绍)作为转轴，凸柱310与第三部件300连接并穿设第二部件200。例如，第二部件200套设在凸柱310上并能够绕凸柱310转动。在一个示例中，凸柱310可以为从第三部件300上延伸出的一体件。
可选的，结合图11-12，第二转轴305可以穿设第三部件300和第二部件200，从而使第三部件300与第二部件200形成转动连接，第三部件300能够绕第二转轴305转动。
可选的，第二转轴305上可以套设蝶形弹片306，蝶形弹片306用于对第三部件300提供转动阻尼。
下面结合不同的实施例对本申请的连接机构的结构进行具体说明。
实施例一
第三部件300具有限位部303，限位部303用于当第三部件300相对第二部件200转动时与转轴机构的第一部件100或第二部件200作用，以限制第三部件300的转动角度。
如图7和图8所示，第三部件300的一端与第一部件100相对，并且两者之间具有第一间隙308，第三部件300的一端用于当第三部件300相对第二部件200转动时与第一部件100作用，以限制第三部件300的转动角度，第三部件300的一端形成限位部303。
如图7和图8所示，第一部件100朝向第三部件300的一端的上侧和下侧分别形成上限位面108和下限位面109。第三部件300上的限位部303包括上限位部和下限位部。第一部件100的上限位面108与上限位部限制第三部件300上摆的角度(参见图7)，第一部件100的下限位面109与下限位部限制第三部件300下摆的角度(参见图8)。
可选的，第一部件100包括第一部件主体和连接于第一部件主体的转轴连接件。转轴连接件的朝向第三部件300的一端的上侧和下侧分别形成上限位面和下限位面，以限制第三部件300的摆动角度。
继续结合图1至图8，第三部件300包括由两侧壁301和底壁302围成的框形结构，第二部件200设于框形结构内。两侧壁301与第二部件200之间具有第二间隙309，当第三部件300相对第二部件200转动时，第二部件200能够与两侧壁301作用，以限制第三部件300的转动角度，两侧壁301形成限位部303。需要说明的是，本实施例的图示中的第二间隙309较大，该仅是一种示意，如果调整第二间隙309的大小，或者是在第二间隙309设置凸起311、312，第三部件300转动时，第二部件200会对第三部件300的两侧壁301或是凸起311、312造成干涉，从而阻碍第三部件300继续转动。第二部件200能够形成对第三部件300转动的限位，从而限制第三部件300的转动范围。
例如，图1所示的示例中，底壁302的靠近两侧壁301的位置设置有凸起311，以将第二部件200限定在两个凸起311之间，在第三部件300相对第二部件200转动时，限定两者的转动位移。或例如，图2所示的示例中，两个侧壁设置有相向延伸的凸起312，以在第三部件300相对第二部件200转动时，限定两者的转动位移。
如图3至图8所示，底壁302上设有第一齿部304，第二部件200上设有与第一齿部304适配的第二齿部217，当第三部件300相对第二部件200转动时，第一齿部304和第二齿部217弹性接触且相对移动以提供转动阻尼。通过设置相啮合的第一齿部304和第二齿部217，能够增加转动过程的顿挫手感，并可以停止于转动后的角度。
第二齿部217包括多个齿，相邻的齿之间形成齿槽。第一齿部304可以包括多个齿(相邻的齿之间形成齿槽)，也可以包括一个齿。在连接构件300(第三部件)位于图7所示的位置时，第一齿部304和第二齿部217的位于图中下方的齿相啮合。在连接构件300(第三部件)位于图8所示的位置时，第一齿部304和第二齿部217的位于图中上方的齿相啮合。也即，在连接构件300(第三部件)相对第二部件200转动时，第一齿部304和第二齿部217中的不同的齿相啮合。
可选的，在一个示例中，第一齿部304和第二齿部217可以具有弹性，以在第一齿部304相对第二齿部217移动时，第一齿部304和第二齿部217弹性形变，以使得第一齿部304能卡入不同的齿槽中。在没有外力的作用下，连接构件300(第三部件)和第二部件200保持在该位置。
可选地，底壁302上的第一齿部304为突出于底壁302的齿部，第二部件200的第二齿部217为布置在第二部件200的凹部的齿部，以能节约空间。
继续结合图5，底壁302上设有位于框形结构内的凸柱310，第二部件200设于框形结构内，凸柱310穿设第二部件200。该实施例中，凸柱310可以替代第二转轴305形成转轴。凸柱310与第三部件300相对固定。第二部件200套设在凸柱310上，并能绕凸柱310转动，以使得第三部件300通过凸柱310转动连接于第二部件200。凸柱310可以具有中心孔，销轴305装设于凸柱310的中心孔。蝶形弹片306抵压于凸柱310(第二转轴)与销轴305的头部之间。如此，可以让销轴305包括头部在内的整体均处于第三部件300的框里，能够提高产品的美观性，保护销钉及配件，延长使用寿命。
如图3、图4和图6所示，凸柱310的端部为长圆柱形，第二部件200上的对应凸柱310的端部的孔为圆孔，第三部件300的凸柱310上的中心孔为圆孔，即轴销305与第二部件200保持相对静止(两者固定)，第二部件200相对第三部件300可以绕凸柱310转动，实现第三部件300的上下摆动的功能。另外，凸柱310(第二转轴)上还可以套设有摩擦片307，摩擦片307设于凸柱310与蝶形弹片306之间。
蝶形弹片306具有弹性其初始形状为曲面(参见图9)，销轴305组装入第二部件200的对应孔时，挤压蝶形弹片306，强制其变形为平面(参见图10)，销轴305与第二部件200的对应孔可以为过盈配合，确保销轴305不会因蝶形弹片306的回弹力被顶出。销轴305与第二部件200也可以采用铆接或焊接等方式进行固定，同样可以确保销轴不会因蝶形弹片306的回弹力被顶出，此时由于蝶形弹片306始终受挤压，提供转动过程的阻尼手感。
可选的，在一个示例中，第三部件300和第二部件200在相对转动时，第一齿部304和第二齿部217也相对移动。在两个齿部的最高点相接触时，迫使第二部件200在沿着凸柱310的轴向上向外(远离底壁302)有轻微的移动，在两个齿部的最低点相接触时，第二部件200在沿着凸柱310的轴向上向内(靠近底壁302)有轻微的移动。由于第二部件200上套设有蝶形弹片306，当第三部件300相对第二部件200转动时，第一齿部304和第二齿部217能在蝶形弹片306的形变作用下弹性接触。
销轴305与蝶形弹片306的配合，形成阻尼轴。阻尼轴提供的是无级阻尼手感。第一齿部304和第二齿部217的配合提供的是有级阻尼手感。阻尼轴和齿部可以同时设置，也可以仅设置齿部而不设置阻尼轴，或是仅设置阻尼轴而不设置齿部。
实施例二
如图11至图18所示，实施例二与实施例一的区别在于第二转轴(销轴305)是从第三部件300的外侧穿过第三部件300后与第二部件200连接。实施例一中的第二转轴(凸柱310)是从第三部件300的内侧穿过第二部件200和第三部件300。实施例二的其他部分的结构与实施例一基本相同，在此不再赘述。
销轴305的端部为长圆柱形，第二部件200上的对应销轴端部的孔为相互匹配的长圆孔，第三部件300的凸柱310上的中心孔为圆孔，即轴销305与第二部件200保持相对静止(两者固定)，第三部件300相对第二部件200可以绕轴销305转动，实现第三部件300的上下摆动的功能。另外，销轴305上还可以套设有摩擦片307，摩擦片307设于销轴305与蝶形弹片306之间。
在该实施例中，销轴305可以为第二转轴305，销轴305可以穿设第三部件300和第二部件200，并与第二部件200固定，从而使第三部件300绕着销轴305与第二部件200形成转动连接，第三部件300能够绕第二转轴305相对第二部件200转动。
本公开实施例还提供了一种转轴机构，例如图19至图41所示，第一部件和第二部件通过第一转轴201装配在一起共同形成转轴机构。转轴机构可以包括第一转轴201、第一部件100、第二部件200和配合部102；第一部件100具有第一抵接部101。第二部件200具有第二抵接部202；第二部件200通过第一转轴201转动连接于第一部件100，第二部件200相对第一部件100在预设角度范围内可转动，且第二部件200具有第一位置和第二位置。可选择的，第一部件100或者第二部件200包括配合部102。当配合部102形成于第一部件100时，配合部102与第一抵接部101衔接且两者之间形成第一夹角α。当配合部102形成于第二部件200时，配合部102与第二抵接部202衔接且两者之间形成第二夹角β。可选的，第一夹角α和第二夹角β限定了第二部件200相对第一部件100的转动角度范围。也就是，当配合部102形成于第一部件100时，预设角度范围为0～180°-α；当配合部102形成于第二部件200时，预设角度范围为0～180°-β。α和β的取值可以根据转轴机构实际应用的领域及产品，以及实际需要转动的角度确定。另外，α和β可以相等也可以不等。
例如，配合部102与第一抵接部101(或，第二抵接部202)衔接，可以是配合部102与第一抵接部101(或，第二抵接部202)设置在同一个部件上，两个部分连续的延伸，或是设置在不同的部件上，两个部分连续的延伸。可以理解的是，配合部102与第一抵接部101(或，第二抵接部202)之间也可以具有间隔。
举例来说，转轴机构可以应用于眼镜，眼镜的镜腿405与第二部件200连接，眼镜的镜框404与第一部件100连接，第二部件200能够带动镜腿405相对第一部件100和镜框404转动，实现镜腿405的外张，使眼镜能够适用于不同的佩戴者的头围，且方便佩戴。例如，当镜腿405需要外张10°～15°时，第一夹角和第二夹角可以分别设置为165°～170°。
可以理解的，本公开实施例的转轴机构可以单独应用于眼镜，使得该眼镜的镜腿在展开后可以进一步的外扩。本公开实施例的转轴机构也可以与上述实施例中的第三部件一起构成连接机构以应 用于眼镜，使得该眼镜的镜腿在展开后可以进一步的外扩之外，还能上下摆动。
在一个示例中，本公开提供一种眼镜，眼镜可以包括容纳镜片的镜框和镜腿。可以由镜框自身设置为第一部件，第二部件通过转轴与镜框可转动连接，镜腿通过第二部件与镜框连接。镜框设置有位于镜框内侧壁的第一平面和与第一平面形成夹角的斜面。第二部件设置有第二平面，该第二平面包括对应第一平面的第一部分和对应斜面的第二部分。第二部件可通过转轴相对镜框在第一位置和第二位置之间转动，在第一位置，第一平面与第二平面的第一部分贴合，在第二位置，斜面与第二平面的第二部分贴合。
当配合部102形成于第一部件100，第二部件200位于第一位置时，第一抵接部101与第二抵接部202相作用，使第二部件200保持在第一位置。当配合部102形成于第一部件100，第二部件200位于第二位置时，配合部102与第二抵接部202相作用，使第二部件200保持在第二位置。当配合部102形成于第二部件200，第二部件200位于第一位置时，第一抵接部101与第二抵接部202相作用，使第二部件200保持在第一位置。当配合部102形成于第二部件200，第二部件200位于第二位置时，第一抵接部101与配合部102相作用，使第二部件200保持在第二位置。
本申请实施例的转轴机构，通过在第一部件100和第二部件200上设置配合部，并在第一部件100和第二部件200上分别设置抵接部，使得第二部件200能够相对第一部件100转动，且在转动时配合部与抵接部作用以及抵接部与抵接部作用之间切换，而使第二部件200能够保持在转动后的第一位置或第二位置，实现第一部件100和第二部件200之间角度的调节。
可选的，可以在第一部件100和第二部件200上设置斜面，并在第一部件100和第二部件200上分别设置平面，使得第二部件200能够相对第一部件100转动，且在转动时斜面与平面作用(例如斜面与平面贴合)以及平面与平面作用(例如平面与平面贴合)之间切换。可以理解的，上述的术语“平面”和“斜面”都可以具有基本平坦的表面，“斜面”是因为相对术语“平面”呈一定角度而命名的。可选的，配合部也可以为具有曲面、凹部或凸起等的结构，抵接部也可以为具有曲面、凹部或凸起等的结构。
在一个示例中，第一抵接部为第一平面，第二抵接部为第二平面，配合部可以配置为如下布置中的一种。第一部件包括配合部，配合部为相对第一平面呈第一夹角的斜面，第二部件位于第一位置时，第一平面与第二平面贴合，第二部件位于第二位置时，斜面与第二平面贴合。第二部件包括配合部，配合部为相对第二平面呈第二夹角的斜面，第二部件位于第一位置时，第一平面与第二平面贴合，第二部件位于第二位置时，斜面与第一平面贴合。
可选的，第一抵接部、第二抵接部和配合部可以设置在第一部件和第二部件之间的部位，并被第一部件和/或第二部件遮挡，以从外部不易观察到。
在一些实施例中，转轴机构还可以包括弹性件，弹性件设于第一部件100和第二部件200之间，用于对第二部件200提供由第二位置朝向第一位置转动的复位作用力，以使在没有外力作用时，第 二部件200能够由第二位置复位至第一位置。
弹性件的具体结构，设置位置以及作用方式本申请均不做具体限定，只要能够对第二部件200提供由第二位置朝向第一位置转动的复位作用力即可。在一个示例中，弹性件可以为弹性体，弹性体可以沿垂直于第一转轴201的轴向的方向可形变，以为第二部件200提供由第二位置朝向第一位置转动的复位作用力，例如在沿基本垂直于第一转轴201的轴向的方向上提供上述复位作用力。
例如，上述转轴机构应用于眼镜的实施例中，当没有外力施加到眼镜上时，第二部件200位于第一位置，眼镜的镜腿405可以理解为处于未外张状态。为了保证镜腿405能稳定的保持在第一位置，可以使弹性件具有一定的形变，以能向第二部件200施加一定的力。当外力施加到眼镜上，使镜腿405外张时，两个镜腿405之间的相对距离增大，以适配不同用户的头围。随着镜腿405外张，第二部件200绕着第一转轴201相对第一部件100转动，第二部件200使得弹性件继续形变，直至第二部件200转动到第二位置。由于配合部102与第一抵接部101或第二抵接部202相作用，第二部件200被限制在第二位置而不能继续转动，弹性件的形变量达到最大，镜腿405随之外张到最大程度。在第二部件200离开第一位置之后，不论是位于第一位置和第二位置之间的位置还是位于第二位置，在形变的作用下，弹性件均能向第二部件200施加力，以使在没有外力作用时，第二部件200能够由第二位置复位至第一位置。
虽然上述以眼镜为例对第二部件200的转动过程中弹性件的变化进行了说明，但是可以理解的是，在上述转轴机构用于其他装置时，也可以类似的理解。
下面以不同的实施例对本申请的转轴机构的具体结构进行介绍。需要说明的是，下文中为了描述的方便，第二部件200由第一位置向第二位置转动时称为外张，第二部件200由第二位置向第一位置转动时称为复位。另外，“上”、“下”、“左”、“右”是针对附图中的位置而言。
实施例一
如图19至图21所示，实施例一中的配合部102形成于第一部件100，弹性件的一端抵于第二部件200的用于与第一部件100的第一抵接部101相作用的部分，另一端抵于第一部件100的与第一抵接部101相对的部分；第一转轴201相对弹性件靠近配合部102。
继续结合图19至图21，弹性件包括压缩弹簧210，压缩弹簧210在沿基本垂直于第一转轴201的轴向的方向可伸缩。可以理解的，在该实施例中也可以选用不同于压缩弹簧210的其他类型的弹性件。第二部件200包括枢转部203，第二抵接部202位于枢转部203的第一侧，枢转部203的第二侧对应第一部件100的第一抵接部101的部分设有弹簧座204，压缩弹簧210的一端定位于弹簧座204，枢转部203的第二侧对应第一部件100的配合部102的部分包括轴座205，第一转轴201穿设轴座205。
例如，图20和图21中的第一部件100的外侧壁、前侧壁和内侧壁限定容腔，容腔的左侧壁301(即外侧壁)的上部形成第一抵接部101，左侧壁301的下部向外侧倾斜形成配合部102。在该示例 中，第一抵接部101可以为平面，相对的，配合部102可以为斜面。第二部件200的上部形成枢转部203，枢转部203的左侧(靠近左侧壁301，也可以理解为面对左侧壁301的一侧)为第一侧，并形成第二抵接部202，第二抵接部202与第一抵接部101和配合部102均对应。在该示例中，第二抵接部202可以为平面。枢转部203的第二侧背离第一抵接部101，可以称之为右侧。枢转部203的右侧上部内凹形成凹部，弹簧座204设于凹部。本实施例中的弹簧座204可以为凸柱，压缩弹簧210的一端可以套设于凸柱上。枢转部203的右侧下部(远离前侧壁的部分)相对其上部形成凸部，凸部作为第一转轴201的轴座205，第一转轴201穿设轴座205。从而使第一转轴201相对压缩弹簧210(弹性件)靠近配合部102，便于压缩弹簧210施力，为第二部件200提供由第二位置朝向第一位置转动的复位作用力。
压缩弹簧210可以为并列设置的多个，例如两个，以为第二部件200提供稳定均衡的复位作用力。
如图20所示，第二部件200处于第一位置时，压缩弹簧210对第二部件200施加使其抵于第一部件100的作用力，第二部件200的第二抵接部202与第一部件100的第一抵接部101贴合，并能够保持在第一位置。当对第二部件200施加使其向图中的左侧(向外)外张的作用力时，第二部件200转动至其第二抵接部202与第一部件100上的配合部102贴合，参见图21，压缩弹簧210仍处于压缩状态，并对第二部件200施加作用力，使其具有由第二位置向第一位置复位的趋势。
实施例二
如图22至图30所示，配合部102形成于第二部件200。弹性件包括分别位于第一转轴201相对两侧的弹性柱，弹性柱分别穿过第二部件200。当第二部件200由第一位置切换至第二位置时，位于第一转轴201不同侧的弹性柱向相反的方向发生弹性形变。通过向相反的方向发生弹性形变的弹性柱，以对第二部件200提供由第二位置朝向第一位置转动的复位作用力。
例如，如图24和图25所示，第二部件200包括位于其第一侧的第一凸部206和位于其第二侧的第二凸部207。弹性柱包括第一弹性柱211和第二弹性柱212，第一弹性柱211穿过第一凸部206且两端与第一部件100固定，第二弹性柱212穿过第二凸部207且两端与第一部件100固定。
继续结合图24和图25，第一部件100包括呈上下相对设置的第一耳板103和第二耳板104。第一转轴201穿过第二部件200，两端分别连接于两个耳板。两个弹性柱的两端分别与两个耳板固定。
如图22所示，第一部件100还包括端板105，两个耳板均设于端板105的板面(表面)上，板面形成第一抵接部101。第二部件200的一端朝向板面，并形成第二抵接部202。第一转轴201平行于第一抵接部101和第二抵接部202。第一弹性柱211和第二弹性柱212在非形变状态(第二部件200处于第一位置时)，两者均与第一转轴201平行。
如图26至图28所示，当第二部件200由图26和图27所处的第一位置向图28所处的第二位置转动，即第二部件200向图26和图28所示的左侧(向外)转动时，第二部件200的第一凸部206 和第二凸部207分别带动穿设其的弹性柱发生弹性形变。图26和图28中位于左侧(外侧)的第一凸部206带动位于左侧的第一弹性柱211向图中所示的上部(当转轴机构应用于智能眼镜时，第一弹性柱211向靠近眼镜的前镜框)发生弹性变形。图26和图28中位于右侧(内侧)的第二凸部207带动位于右侧的第二弹性柱212向图中所示的下部(当转轴机构应用于智能眼镜时，第一弹性柱211向远离前镜框)发生弹性变形。由于弹性柱变形后具有恢复形变的特点，以实现第二部件200外张时的回弹力。
实施例三
如图31至图33所示，配合部102形成于第二部件200。第一部件100和第二部件200限定出容纳部106。弹性件为弹性垫块213，弹性垫块213设于容纳部106内，并同时抵于第一部件100和第二部件200。第二部件200由第一位置转动至第二位置，即向图中的左侧外张至位于第二位置时，第二部件200挤压弹性垫块213，使其发生弹性形变(参见图33)，积蓄弹性势能，从而获得回弹力，以对第二部件200提供由第二位置朝向第一位置转动的复位作用力。即，第二部件200由第二位置向第一位置复位的作用力，可以通过弹性垫块213的回弹力获得。
继续结合图31，第一部件100具有容腔，第二部件200的一端伸入容腔，并与容腔的左侧壁301(外侧壁)之间形成容纳部106。第二部件200伸入容腔的一端的端面形成第二抵接部202。第一部件100的与第二抵接部202相对的表面形成第一抵接部101和配合部102。也就是，容腔的腔底形成第一抵接部101和配合部102。弹性垫块213的第一侧面贴合于第二部件200位于容纳部106内的一侧面，弹性垫块213的第二侧面贴合于容腔的与第二部件200的一侧面相对的侧壁301面。为了固定弹性垫块213，弹性垫块213可以粘贴于容腔的侧壁301面。
实施例四
如图34至图36所示，实施例四与实施例三的区别仅在于将弹性垫块213替换为弹片214。弹片214设于容纳部106内，第二部件200位于第二位置时，弹片214形变，以对第二部件200提供由第二位置朝向第一位置转动的复位作用力。
实施例四中，第二部件200的外张回弹力可以通过弹片214实现。弹片214可以通过粘贴或焊接的方式固定于第一部件100的容纳部106的侧壁301，第二部件200向外转动时压缩弹片214，获得回弹力。
实施例五
如图37至图39所示，弹性件包括由多个弹片依次叠摞形成的弹片组215；弹片组215作用于第二部件200的与第二抵接部202相邻的端面。第二部件200位于第二位置时，弹片组215形变，以对第二部件200提供由第二位置朝向第一位置转动的复位作用力。
继续结合图37至图39，第一部件100具有容腔，容腔的左侧壁301的上部形成第一抵接部101，容腔的左侧壁301的下部形成向外侧倾斜的配合部102。第二部件200的第一端伸入至容腔，弹片 组215位于第二部件200的第一端与容腔的上侧壁301之间。多个弹片由上至下依次叠摞。第二部件200的第一端靠近容腔的左侧壁301的一侧凸出于远离容腔的左侧壁301的一侧，形成凸起，弹片组215作用于凸起的端面。第一转轴201位于凸起的下方，并尽量远离容腔的左侧壁301，以便于弹片组215对第二部件200提供使其由第二位置向第一位置复位的作用力。为了给弹片组215留出形变的空间，容腔的顶侧壁限定凹陷以使弹片组215自由端(作用于凸起的端面)形变，容腔的顶侧壁还设置安装部，以固定弹片组的固定端。
上述各实施例中的第一部件100可以包括第一部件主体和转轴连接件。转轴连接件与第一部件主体可以为一体件。或者，转轴连接件连接于第一部件主体。第一抵接部101形成于转轴连接件，第二部件200通过第一转轴201与转轴连接件转动连接。
上述各实施例中的所有的弹性件均可以提供预紧力，使得第二部件200不易转动。需要说明的是，实施例二中的弹性柱如果要提供预紧力，弹性柱的上中下三点不共线，即，第一耳板103和第二耳板104固定弹性柱的孔以及凸部用于穿过弹性柱孔不共轴，以提前提供预紧力。
如图40至图59所示，本申请实施例还提供了一种眼镜400。眼镜400包括镜框404和镜腿405，眼镜400还包括上述任一实施例的转轴机构；或者眼镜400还包括上述任一实施例的用于眼镜的连接机构420。镜框404和镜腿405通过转轴机构或连接机构420连接。
当眼镜400包括转轴机构时，转轴机构为两套，两套转轴机构的第一部件100分别固定于镜框404，两镜腿405分别铰接于的两套转轴机构的第二部件200。由于第二部件200能够相对第一部件100左右转动，从而使得连接于第二部件200的两个镜腿405能够实现向外掰，从而调节两个镜腿405的距离，以适应不同佩戴者的头围。此外，镜腿405与第二部件200铰接，使镜腿405能够折叠，以方便收纳。
当眼镜400包括连接机构420时，连接机构420为两套，两套连接机构420的第一部件100分别固定于镜框404，两镜腿405分别铰接于的两套连接机构420的第三部件300。由于第二部件200能够相对第一部件100左右转动，从而使得两个镜腿405能够实现向外掰，从而调节两个镜腿405的距离，以适应不同佩戴者的头围。由于第三部件300能够相对第二部件200上下转动，从而使两个镜腿405能上下调节，以适应不同佩戴者的耳朵的高度。此外，镜腿405与第三部件300铰接，使镜腿405能够折叠，以方便收纳。本申请实施例的眼镜400适用性强，佩戴方便，用户使用体验佳。
如图41所示，眼镜400的镜框404与第一部件100可以为分体结构。镜框404上可以设有固定孔406，第一部件100可以通过螺丝407等连接件固定于镜框404上。当然，镜框404也可以直接作为第一部件100；或者镜框404作为第一部件100的一部分；再或者镜框404与第一部件100为一体件。镜框404可以选用塑胶材料，如ABS\PC等。为了保证转动过程抗磨损抗疲劳，第一部件100可以采用为铝合金或不锈钢或聚甲醛POM材质制成。当镜框404和第一部件100为一体件时，两者 可均为金属材料，直接一体模塑，便于装配。
如图40所示，眼镜400为智能眼镜，智能眼镜还包括光学成像系统401。如图60所示，光学成像系统401包括像源组件402和光学组件403。智能眼镜可为AR眼镜、VR眼镜等头戴显示设备。像源组件402用于显示投射到人眼中的图像，光学组件403起到改变光路等作用。
下面结合不同的实施例对镜腿405与第三部件300的连接方式以及数据线408的走线方式进行说明。
实施例一
当眼镜400为智能眼镜时，智能眼镜的镜框404(显示机身)与镜腿405之间通常由数据线408连接。如图42和图43所示，数据线408由显示机身伸出，穿过第三部件300延伸至镜腿405。如图43、图45和图46所示，眼镜400还包括折叠铰链409和铰链固定座410。铰链固定座410固定于镜腿405的内侧，为了方便拆卸，铰链固定座410可以卡接于镜腿405，并通过卡扣固定。折叠铰链409的一端转动连接于第三部件300，另一端与铰链固定座410固定，使镜腿405能够相对第三部件300转动。镜腿405通过折叠铰链409实现与第三部件300的铰接，镜腿405能够折叠和展开，镜腿405折叠后便于收纳和携带。
继续结合图46，折叠铰链409包括铰接部411和第三转轴412，铰接部411具有贯通孔413和贯通其轴向两端并与贯通孔413连通的切口414(参见图49)。第三转轴412穿设贯通孔413并与贯通孔413紧配合，以用于对折叠铰链409提供转动阻尼。
继续参见图45和图46，数据线408延伸至镜腿405内的部分，可以通过铰链固定座410固定于镜腿405内。即，数据线408定位于镜腿405和铰链固定座410之间。本实施例一中的铰链固定座410可以为并列设置的两个。折叠铰链409通过两个螺钉分别与两个铰链固定座410组装固定，以防止折叠铰链409发生扭转，提高稳定性。
如图47和图48所示，眼镜400还包括连接件盖板415和镜腿盖板416，连接件盖板415盖设于第三部件300，用于封盖穿过第三部件300的数据线408。镜腿盖板416盖设于镜腿405上，用于封盖镜腿405内的数据线408。盖板可以使用胶水粘接或是卡接的方式与第三部件300或镜腿405固定。连接件盖板415和镜腿盖板416相对的一端柔性连接，以使两者能够相对转动，能够随镜腿405的折叠，连接盖板和镜腿盖板416在两者的连接处也随之弯折，从而不会妨碍镜腿405的折叠。所谓柔性连接，是相对刚性连接而言，柔性连接是能够在连接处发生转动。例如通过能够发生弹性或柔性形变的部件实现的连接，比如通过硅胶、橡胶、柔性带等的连接。当然，连接件盖板415和镜腿盖板416之间也可以转动连接，以方便在镜腿405弯折时随着转动，而不影响镜腿405的弯折。当然，连接件盖板415和镜腿盖板416也可以为间隙配合，当镜腿405在折叠和展开之间切换时，连接件盖板415和镜腿盖板416彼此相对的一端不会干涉，进而不会影响镜腿405的展开和折叠。镜腿405的展开状态和折叠状态可以参见图49和图50。
实施例二
如图51和图52所示，镜腿405第三部件300通过销钉417和卡簧418的配合实现转动连接。例如，继续结合图51，第三部件300和镜腿405为相对端适配的框形结构，镜腿405的端部包覆于第三部件300的端部外，镜腿405的上侧壁301与第三部件300的上侧壁301分别开设有相对应的上装配孔。镜腿405的下侧壁301与第三部件300的下侧壁301分别开设有相对应的下装配孔。销钉417可以为两个，两个销钉417分别装设于上装配孔和下装配孔。销钉417伸出装配孔外的部分设置卡簧418，以将销钉417限位于装配孔内。
销钉417可以与装配孔紧配合，以提供转动阻尼，参见图54。或者销钉417与装配孔之间设置垫圈419，即，销钉417位于装配孔内的部分套设垫圈419，以提供转动阻尼，参见图55。当然，销钉417也可以用其他类轴状部件替代，并非仅限于销钉417。
如图53所示，镜腿405和第三部件300铰接后，数据线408由镜框404通过第三部件300延伸至镜腿405。如图56和图57所示，眼镜400还包括连接件盖板415和镜腿盖板416，盖板能够将数据线408定位于第三部件300和镜腿405内。连接件盖板415和镜腿盖板416的连接方式、配合方式等可以与实施例一相同，在此不再赘述。
如图58和图59所示，镜腿405能够相对第三部件300展开和折叠，折叠后便于收纳和携带。
本申请实施例的眼镜400，既能实现外张，又能实现上下摆动，又能折叠，提高用户佩戴眼镜400的使用体验。通过弹性柱、压缩弹簧210、弹性垫块213、弹片、弹片组215等实现外张回弹功能，蝶形弹片306提供摆动阻尼，使佩戴更舒适。通过合理的结构排布，实现数据线408由内部穿过，且整体结构密封的功能。
以上描述旨在是说明性的而不是限制性的，本领域的普通技术人员在本公开的范围内可以对上述实施例进行变化、修改、替换和变型。而且上述示例(或其一个或更多方案)可以彼此组合使用，并且考虑这些实施例可以以各种组合或排列彼此组合。本申请的范围应参照所附权利要求以及这些权利要求赋权的等同形式的全部范围来确定。
