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，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动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。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的电子设备进行详细地说明。
如图1所示，根据本申请的一个实施例，提供了一种眼镜，包括主体1、镜腿2和连接装置，镜腿2通过连接装置连接在主体1的端部，以使镜腿2可转动。本实施例所述的眼镜为近视眼镜、遮阳镜、虚拟现实(Virtual Reality，VR)眼镜、电子智能眼镜中的任一种。对于眼镜类型，本申请实施例在此不做限定，本领域技术人员可将本技术方案应用在需要的眼镜上。
连接装置包括第一连接件3、第二连接件4和弹性件，第一连接件3设置在主体1的端部，其可以与主体1形成固定连接，便于使主体1与镜腿形成稳固的连接。
第二连接件4的第一端41与第一连接件3铰接。通过铰接连接形式，第二连接件4与第一连接件3形成旋转连接的配合关系，使得与第二连接件4固定连接的部件能够相对于主体1以及第一连接件3旋转。第二连接件4的第二端42与镜腿2铰接，两者之间也形成旋转配合的连接关系。
弹性件位于第二连接件4和镜腿2之间，弹性件的第一弹性端与镜腿2相抵，弹性件的第二弹性端与第二连接件4相抵，通过这种抵顶的配合方式，在镜腿2远离主体1转动的情况下，弹性件驱动镜腿2和第二连接件4远离彼此。弹性件用于在第二连接件4和镜腿2之间形成预紧的弹性作用力，从而在实际应用中，使得镜腿2在被相对于第二连接件4扳动旋转时能够向相反的方向产生夹紧的弹性作用。
可选地，所述弹性件的主要结构可以固定在第二连接件上，主要通过第一弹性端与镜腿2接触，产生弹性作用力。这种实施方式的弹性件更靠近主体1，有助于提高弹性件、镜腿2与主体的连接可靠性。在另一种可选的实施方式中，所述弹性件的主要结构也可以固定在镜腿2上，弹性件主要通过第二弹性端与所述第二连接件4形成接触，产生弹性作用力。这种实施方式有助于将镜腿2与第二连接件4的旋转范围设计更大，增大镜腿2相对于第二连接件4和主体1的活动范围。
此外，在实际应用中镜腿2和第二连接件4有可能设计成扁平的条 状、片状结构，以提高眼镜的美观程度。所述弹性件可以整体位于镜腿2和第二连接件4的内侧，也即更靠近佩戴者的一侧，以改善眼镜的整体美观程度。或者，所述弹性件也可以整体位于镜腿2和第二连接件4的外侧，也即远离佩戴者的一侧，这种设计方式更便于是弹性件发挥将镜腿夹紧在佩戴者头部上的作用，结构简单。此外，也可以将弹性件的一部分设置在靠近佩戴者的一侧，另一部分设置在远离佩戴者的一侧，以便对第二连接件和镜腿的结构进行设计。本申请对此不进行限制。
可以理解的是，第二连接件的第一端与第一连接件的铰接，允许第二连接件和镜腿相对于主体转动，从而可以将镜腿与主体折叠起来，减小眼镜的体积，方便收纳。第二连接件的第二端与镜腿铰接，允许镜腿相对于第二连接件转动，便于镜腿适应不同佩戴者的头部尺寸。
在镜腿远离主体转动的情况下，将会首先释放折叠而展开，第二连接件和镜腿同步转动至方便佩戴者佩戴的位置；在镜腿进一步远离主体转动时，镜腿相对于第二连接件发生转动，以适应佩戴者的头部尺寸，在此过程中弹性件发生形变，使弹性件蓄能，弹性件具有恢复原状的特性，从而弹性件驱动镜腿和第二连接件远离彼此，就可以使镜腿紧固在佩戴者的头部上，使得眼镜穿戴牢固，提高灵活性。
本实施例的眼镜的镜腿2由于通过连接装置与主体1连接，连接装置的第二连接件4与镜腿2由于是铰接，所以，在镜腿2挂在耳部上后，弹性件能够自动驱动镜腿2夹在头部上，从而实现了眼镜穿戴牢固的效果，提高灵活性。
当然，上文仅描述了一只镜腿与本体的连接结构及作用关系，可以理解的是，眼镜还可以具备两只镜腿。当镜腿为两只的情况下，一只镜腿连接在主体的一端，另一只镜腿连接在主体的另一端，两只镜腿可分别通过连接装置与主体连接，可以理解的是，两只镜腿的转动方向相反。
在如图4所示的示例中，在使用本申请实施例的眼镜时，将两个镜腿2向远离主体的方向旋转展开，此时镜腿2通过弹性件带动第二连接件4以第二连接件4与第一连接件1的铰接点为圆心转动。随着两个镜腿2之间的宽幅增加，并将两个镜腿2挂在耳部上后，弹性件驱动镜腿2向靠近主 体的方向运动，使两个镜腿2夹在头部上。
此外，第二连接件4与镜腿2铰接，在两个镜腿2展开相平行后，如果两个镜腿2之间的宽幅仍小于佩戴者头部宽幅。佩戴者可通过分别向外侧扳动两个镜腿2以扩大镜腿之间的宽幅，镜腿2以铰接点为圆心转动。佩戴者施加的扳动作用力，会使得弹性件产生形变进而对镜腿2产生弹性作用力。该弹性作用力会使得镜腿2具有相互靠近的趋势。这样，两支镜腿2能够夹在佩戴者的头部，保证佩戴的稳定性。在佩戴者摘下眼镜时，两支镜腿2在弹性件的作用下，会绕着第二连接件旋转，恢复到相互靠近的姿态。
如，佩戴者可以通过扳动镜腿使其向外侧旋转0-30°。本实施例的眼镜还实现了无需镜腿自身变形便可实现调节两个镜腿2之间宽幅的效果。最终实现了可供头部宽幅不同的人群使用，无需另外设置多个规格，从而减少了生产成本和采购费用。
可选地，如图1和图2所示，在一个实施例中，第一连接件3包括第一限位部31，第一限位部31设置在第一连接件3的邻近第二连接件4连接的一端，在第二连接件4相对于第一连接件3远离主体1转动到预设角度范围的情况下，第二连接件4与第一限位部31抵接，从而实现限位，阻止两者进一步相对旋转，以使第二连接件4、镜腿2在主体1与第一限位部31之间的范围内转动。
如图4所示，第一限位部31可以设置在第一连接件3远离主体的一侧，第二连接件4向远离主体1的方向转动90°时，第二连接件4与第一限位部31抵接。如图5所示，第二连接件4向靠近主体1的方向转动90转时，其中一个镜腿2与主体1相抵。此时，主体1两端的第二连接件4相互平行，主体1两端的镜腿2相互平行。
第二连接件4的转动角度不限于90°，可以为小于90°，也可以为大于90。本领域技术人员可根据实际需求设置第一限位部的形状和位置，以限定第二连接件4的活动角度范围。
进一步的，第一限位部31可以设置在第一连接件3的邻近第二连接件 4连接的一端的上端面或下端面处，第二连接件4向远离主体的方向转动时，第二连接件4的一部分与第一限位部31抵接。可选地，第一限位部31呈从第一连接件3上延伸出的片状结构。第二连接件4与第一限位部31相抵接时，所述第一限位部的表面与第二连接件4的表面与片状的第一限位部31的表面接触。
如图1和图2所示，第一限位部31与第一连接件3可以为一体形成以提高整体强度。第一限位部31与第一连接件3不限于一体成型，也可以为焊接、铆接、螺栓连接中的任一种，本领域技术人员可根据实际需要设置第一限位部31与第一连接件3的连接关系。
通过设置第一限位部，能够避免佩戴者在将镜腿从靠近主体的位置扳动至远离主体的位置时出现过度扳动的现象。第一限位部能够限制第二连接件相对于主体的最大转动姿态，使得眼镜能够正常、稳定的被佩戴在头部。
可选地，在一个实施例中，第二连接件4的第二端42设有第二限位部，第二限位部具有预设限位角度，镜腿2在预设限位角度内可转动，由于第二限位部使镜腿2在预设限位角度内可转动，实现了对镜腿2的转动可控的效果。
例如，预设限位角度为±30°。即镜腿2在弹性件的驱动下向内自动转动30°时与第二限位部的一部分相抵，并停止向内转动。
镜腿2在手部向外掰的驱动下向外转动30°时与第二限位部的另一部分相抵，并停止向外转动。此时两个镜腿2之间的宽幅增加，可供头部宽幅大的人群使用。
第二限位部对镜腿2的预设限位角度不限于±30°，本领域技术人员可根据实际需要设置第二限位部的限位角度。
通过设置第二限位部可以有效避免镜腿相对于第二连接件过度旋转而造成不便使用的情况。并且，也能够降低眼镜受损的风险，降低镜腿与第二连接件之间出现折断的风险。
可选地，如图1和图3所示，在一个实施例中，第二限位部包括第一 通孔43，镜腿2和第二连接件4之间设置有第一柱状部5，第一柱状部5在第一通孔43内可移动。
例如，第一通孔43设置在第二连接件4的第二端42上，第一柱状部5设置在镜腿2上，且第一柱状部5插入第一通孔43内。第一通孔43直径大于第一柱状部5的直径以使第一柱状部5在第一通孔43内可移动。
如图3所示，例如，镜腿2在弹性件的驱动下向靠近主体的方向自动转动30°时，镜腿2上的第一柱状部5与第二连接件4的第一通孔43的第一侧孔壁431相抵，形成限位。通过第一通孔43的限位作用，镜腿2无法进一步旋转。
如图3所示，例如，在佩戴者将镜腿2向远离主体1的方向扳动，使镜腿2向远离主体1的方向转动30°时，镜腿2上的第一柱状部5与第二连接件4的第一通孔43的第二侧孔壁432相抵，形成限位。通过第一通孔43的限位作用，镜腿2无法被进一步向远离主体的方向扳动。并停止向外转动。此时两个镜腿2之间的宽幅增加，可供头部宽幅大的佩戴者使用。
本申请可以通过对第一柱状部和第一通孔的尺寸进行预先设定，从而对镜腿相对于第二连接件的旋转角度进行限制，以达到便于佩戴者使用、扳动，又不至于出现镜腿被过度扳动的情况。例如，在第一通孔的直径固定的设计方式中，第一柱状部的直径越大，镜腿相对于第二连接件的可旋转角度范围就越小。反之则范围越大。或者，在第一柱状部的直径固定的设计方式中，第一通孔的直径越小，镜腿相对于第二连接件的可旋转角度范围就越小。反之则范围越大。
这种配置第二限位部的优点在于，第二限位部与通孔具有良好、稳定的配合关系。第二限位部与第一柱状部形成插接关系，不易出现松动、相互脱离等造成限位失效的情况。并且，这种结构的加工、装配过程简单。
所述第二限位部除了可以采用上述结构实现之外，还可以采用其它结构实现这种限位功能。
可选地，第二限位部可以采用与第一限位部相似的片状延伸结构。所述第二连接件上可以在远离主体的位置延伸出片状结构，用于对镜腿的位置进行限制。在镜腿受到外力，被向远离主体的方向扳动的状态下，镜腿 旋转一定角度后会与片状结构相互抵顶。呈片状结构的第二限位部可以实现对镜腿的限位。
可选地，所述第二连接件上靠近主体的位置也可以延伸出片状结构，作为第二限位部的另外一半结构。在镜腿不受外力扳动的情况下，镜腿在弹性件的作用下，其表面可以与第二连接件上的靠近主体的片状结构形成抵顶，构成限位。
以上实施方式同样可以实现第二限位部对镜腿的限位作用，并且结构简单，易于装配。通过对两个片状结构之间的距离进行设计，可以对镜腿的旋转角度范围形成限制。对于采用片状结构作为第二限位部，可以根据实际产品需求设计两个片状结构以对两个方向的角度均形成限制，也可以选择只设置其中一个，达到一个方向上的限位即可。
如图1至图5所示，在一个实施例中，弹性件为扭簧6，扭簧6通过安装轴44安装在第二连接件4上。扭簧6的第一扭臂61构造为第一弹性端，第一扭臂61与镜腿2相抵，扭簧6的第二扭臂62构造为第二弹性端，第二扭臂62与第二连接件4相抵。扭簧6的材质为硅锰弹簧钢丝、铬钒弹簧钢丝、铬硅弹簧钢丝中的任一种。扭簧6的第一扭臂61可以存储和释放镜腿2转动产生的弹性势能。扭簧能够对旋转配合的第二连接件和镜腿产生稳定、可靠的弹性作用力，使得镜腿能够产生向靠近佩戴者头部的方向夹紧的作用力。通过将扭簧的第一扭臂和第二扭臂分别抵顶在镜腿和第二连接件上，能够有效的传递弹性作用力。
可选地，为了进一步提高第一扭臂和第二扭臂抵顶在两个部件上的稳定性，第二连接件和/或镜腿上可以形成有沉孔。第一扭臂和第二扭臂的端部可以弯折插入至沉孔中，从而避免扭臂相对于其所抵顶的部件出现错动的现象。此外，也可以在第二连接件和/或镜腿上设置定位槽，用于限制扭臂的位置。
对于扭簧装配于第二连接件和镜腿上的方式，一种可选的实施方式如图1所示。第二连接件4上设置有第一安装孔45，安装轴44安装在第一安装孔45内，扭簧6套设在安装轴44上。安装时，将扭簧6的中部的环形部套在安装轴44外，将安装轴44通过第一安装孔45固定在第二连接件4 上。通过设置供扭簧套设的安装轴，能够有效增加扭簧设置在第二连接件上的稳定性，提高镜腿与第二连接件之间的弹性旋转配合可靠性。
如图1和图2所示，在一个实施例中，第一扭臂61抵接于镜腿2的远离主体1的一侧；第二扭臂62抵接于第二连接件4的远离主体1的一侧。这样，一旦镜腿被向远离主体的方向扳动旋转，扭簧就能够产生弹性作用力，使镜腿具有向靠近主体的方向移动的趋势。进一步地，扭簧可以具有一定预紧力，这样使得扭簧6的第一扭臂61对镜腿2始终施加朝靠近主体的方向转动的推力，实现了镜腿2具有自动夹持的效果。佩戴者将眼镜佩戴上后，镜腿在弹性作用力下能够夹住佩戴者头部，提高佩戴可靠性。
可选地，弹性件也可以为片簧、弹性橡胶等能够稳定产生弹性作用力的弹性部件。
可选地，所述弹性件为片簧。片簧的中部固定在第二连接件4上。固定方式可以为焊接，也可以为通过螺栓连接在第二连接件4上。本领域技术人员可根据实际需要设置片簧的连接方式。
例如，片簧的第一扭臂构造为第一弹性端，第一扭臂抵接于镜腿2的远离主体1的一侧；片簧的第二扭臂构造为第二弹性端，第二弹性端抵接于第二连接件4的远离主体1的一侧。即片簧的第一扭臂始终对镜腿2释放朝内转动的推力，以实现镜腿2自动夹持的效果。片簧的装配方式更简洁，能够简化第二连接件与镜腿之间的连接关系。并且，片簧也能够稳定的提供弹性变形的作用力。
如图1、图2和图4所示，在一个实施例中，镜腿2包括支腿21和与支腿21连接的第三连接件22，第三连接件22与第二连接件4的第二端42铰接。弹性件位于第三连接件22和第二连接件4之间，弹性件的第一弹性端与第三连接件22相抵，弹性件的第二弹性端与第二连接件4相抵，在第三连接件22远离主体1转动的情况下，弹性件驱动第三连接件22和第二连接件4远离彼此。
支腿21和第三连接件22的远离第二连接件4的一端连接。可选地，连接方式为螺钉连接。
在使用本实施例的眼镜时，将两个镜腿2向外侧方向展开，此时支腿 21通过第三连接件22和弹性件带动第二连接件4相对于主体1转动。
当两个支腿21之间的宽幅增加，并将支腿21挂在耳部上后，弹性件驱动第三连接件22、支腿21向靠近主体1的方向的运动(即向内侧转动)，使两个支腿21夹在头部上。
此外，由于第二连接件4与第三连接件22铰接，支腿21和第三连接件22是固定连接，在第二连接件以及支腿21相对于主体1完全展开相平行后，如果两个支腿21之间的宽幅仍小于佩戴者的头部宽幅，佩戴者可通过分别向外侧转动两个支腿21以扩大宽幅，支腿21带动第三连接件22以铰接点为轴心转动。例如，转动1°～30°。进而使得支腿21带动第三连接件22向远离主体1的方向转动。此时弹性件产生弹性变形和弹性作用力。眼镜被佩戴后，弹性件驱动第三连接件22、支腿21向镜腿2的靠近主体1的方向的夹紧。
通过设计第三连接件和支腿，可以使得眼镜的结构、材料更多样化。第三连接件可以采用结构强度好、有利于实现稳定旋转连接的材料制成。而所述支腿则可以采用亲肤性好，外形更美观的材料制成。这种设计方式能够更好的满足眼镜的性能要求。
如图1所示，在一个实施例中，第一连接件3、第二连接件4和第三连接件22均为槽形板，第二连接件4的第一端41套设在第一连接件3的一端内，第二连接件4的第二端42套设在第三连接件22的一端内，所述第一柱状部5设置在第三连接件22的第二安装孔222上，并插入第二连接件4的第一通孔43内以使第三连接件22、支腿21的转动可控。
一方面，将上述部件设置为槽形板能够增大各部件的面积，从而提高佩戴者的佩戴舒适度，降低加持作用力可能产生的佩戴不适感。另一方面，槽形板结构的强度更高，各个连接件的结构可靠性得到提高。
第一连接件3、第二连接件4和第三连接件22不限于为槽形板，本领域技术人员可根据实际需求设置第一连接件3、第二连接件4和第三连接件22的形状。
如图1所示，在一个实施例中，第一连接件3的一端的两侧壁板上分别设有相对的第一铰接孔32。第二连接件4的第一端41的两侧壁板上分别 设有相对的第二铰接孔46。第二连接件4的第二端42的两侧壁板上分别设有相对的第三铰接孔47。第三连接件22的一端的两侧壁板上分别设有相对的第四铰接孔221，第一铰接孔32和第二铰接孔46重合，并通过第一轴7铰接，第三铰接孔47和第四铰接孔221重合，并通过第二轴8铰接。
如图1所示，在一个实施例中，第一连接件3、第二连接件4和第三连接件22分别设有减重孔以降低连接装置的整体重量。减重孔可以开设在连接件上不用于与其它部件形成铰接、固定连接的部分。例如，在各个连接件为槽形板的实施方式中，所述减重孔可以开设在槽形板的面积最大的表面上。也即各个连接件的侧面板上。这样既可以起到减重的作用，又能够产生美化眼镜外观的作用。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。此外，需要指出的是，本申请实施方式中的方法和装置的范围不限按示出或讨论的顺序来执行功能，还可包括根据所涉及的功能按基本同时的方式或按相反的顺序来执行功能，例如，可以按不同于所描述的次序来执行所描述的方法，并且还可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
