附图标号说明：

本申请目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
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描述，显然，所描述的实施例仅仅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做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。
需要说明，若本申请实施例中有涉及方向性指示(诸如上、下、左、右、前、后……)，则该方向性指示仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
目前的头戴显示设备，例如但不限于AR(Augmented Reality，增强现实)眼镜、VR(Virtual Reality，虚拟现实)眼镜、及MR(Mixed Reality，混合现实)眼镜，其使用的镜腿与镜架之间的连接结构，通常为简单的铰接结构，针对头部尺寸较小的用户而言，镜腿无法较好地贴服在耳朵上，导致单侧镜腿滑脱，甚至设备整体脱落的问题。
鉴于此，本申请提出了一种镜腿连接结构，用于头戴显示设备，头戴显示设备包括镜架和分设于镜架两端的两镜腿，参照图1至5，在本申请一实施例中，该镜腿连接结构包括：
基座10；
安装支架20，转动连接于基座10，安装支架20设有两个，其中一安装支架20用以与镜架71连接，另一安装支架20用以与镜腿73连接；
夹持弹性件30，对应安装支架20设置，并连接于安装支架20与基座10之间。
本申请技术方案中，通过夹持弹性件30向安装支架20提供夹紧力，该夹紧力能够使两安装支架20上的镜架71和镜腿73在一定的位置范围内，具有相互靠拢的趋势，从而不仅能在佩戴后经两个镜腿73的夹紧作用，而使镜腿73能够更贴服地佩戴在耳朵上，进而提升镜腿73佩戴的稳定性和可靠性，并使设备不容易从用户身上脱落，还能使设备能适配不同的用户头部尺寸，进而提升用户体验，并提升设备的市场竞争力。具体而言，假设镜腿73处于折叠状态时与镜架71的夹角为0°，并假设为满足不同头部尺寸的佩戴需求，镜腿73被设置为展开至佩戴状态时与镜架71的夹角范围为80°至100°，则夹持弹性件30可被配置为在镜腿73夹角大于或等于70°后开始产生夹紧力。容易理 解的，针对头部尺寸较小的用户，其对应的镜腿73佩戴夹角为80°，则夹持弹性件30产生的夹紧力也会较小；而针对头部尺寸较大的用户，其对应的镜腿73佩戴夹角为100°，则夹持弹性件30产生的夹紧力也会较大。所以，本申请技术方案能够适配一定范围内的头部尺寸，并为这一群体的用户在佩戴设备时提供镜腿73夹紧力，从而使两侧的镜腿73均不易从耳朵处滑脱，并避免设备脱落的情况出现。当然，在其他实施例中，还可以是设定为其他夹角数值，例如夹角大于或等于20°(或45°，或90°)后开始产生夹紧力。
请参照图3、5和6，本实施例中，可选地，夹持弹性件30配置为扭簧。扭簧具有结构简单、工作稳定及使用寿命长的优势，有利于降低设备的制造成本，并降低设备的故障率。当然，在其他实施例中，夹持弹性件还可以是发条弹簧、日式弹簧卡或U型弹簧片等。
本实施例中，进一步地，扭簧具有柱状的螺旋部31、及分设于螺旋部31两端的两安装部32，其中一安装部32与基座10连接，另一安装部32与安装支架20连接，螺旋部31的相邻两圈结构之间形成有间隙设置；安装支架20凸设有安装柱24，扭簧套设于安装柱24，安装柱24的穿过扭簧的一端设有第一螺纹部241，镜腿73连接结构还包括第一紧固件41，第一紧固件41螺纹连接于第一螺纹部241，并抵持于扭簧的螺旋部31。具体的，本实施例中，第一螺纹部241为外螺纹柱，第一紧固件41对应设为螺母；当然，在其他实施例中，还可以是第一螺纹部为螺纹孔，第一紧固件对应设为螺栓，螺栓的螺帽抵持于扭簧的螺旋部。具体而言，本实施例中扭簧为圆柱形螺旋扭力弹簧，且为非密身设置，也即，扭簧的相邻两圈结构(钢丝)之间具有间隙，如此，扭簧的轴向长度可进行调整(被压缩)。本实施例中，通过调节螺母在安装柱24上的旋进量，来调节(压缩)扭簧上相邻两圈结构之间的间隙，从而调节扭簧的轴向长度，进而调节扭簧的实际工作扭矩并使之符合设计要求，进而使量产状态下不同产品的镜腿73旋转操作力趋于一致，也即，提升产品的品质一致性，并提升市场竞争力。容易理解的，安装柱24主要起到与第一紧固件41配合地调节扭簧沿轴向长度的作用，所以不论安装柱24是设置在安装支架20或基座10上，均能够实现上述作用，在此不做具体限定。
请参照图1、4、6和9，本实施例中，进一步地，安装支架20对应扭簧设有第一限位槽25，第一限位槽25沿安装柱24的周向延伸，并具有相对的第一 端壁251和第二端壁252，扭簧的安装部32在第一限位槽25内滑动；安装支架20具有多个转动位置，多个转动位置包括依次设置的折叠位置、适配位置及外翻位置，于折叠位置至适配位置之间，安装部32脱离第一端壁251；于外翻位置，安装部32抵接于第一端壁251，且扭簧产生弹性作用力，以使安装支架20具有朝适配位置转动的趋势。具体的，请一并参照图11至13，图11中两安装支架20均处于折叠位置，图12中两安装支架20均处于适配位置，图13中两安装支架20均处于外翻位置，可以看出，图12中两安装支架20之间的夹角为钝角，图13中两安装支架20之间的夹角超过180°。另外，于折叠位置，安装部32可以抵接于第二端壁252，也可以不抵接于第二端壁252。需要说明的是，安装支架20的折叠位置对应镜腿73的折叠状态，适配位置至外翻位置之间的转动范围则对应镜腿73的佩戴状态，如此，就能够保证镜腿73在佩戴状态下会对外产生夹紧作用力。其次，由于安装支架20在折叠位置至适配位置之间的转动，扭簧不产生弹性作用力，所以镜腿73能够轻松转动，从而既方便用户展开并佩戴镜腿73，又能在佩戴后不会造成过大的夹紧力，进而提升佩戴舒适性。当然，在其他实施例中，还可以是安装支架不设置第一限位槽，而设置插孔，扭簧的安装部插设于插孔内。
需要说明的是，本实施例中，两安装支架20分别安装在镜腿73和镜架71上，请参照图16和17，图16为镜腿连接结构中两安装支架的夹角为90°时的状态，图17为两安装支架的夹角为180°时的状态。其中，安装于镜架71上的安装支架20与镜架71之间的夹角为90°或接近90°设置，而安装在镜腿73上的安装支架20与镜腿73之间的夹角为零度或接近零度设置。如此，当镜腿73处于折叠状态，也即，镜腿73与镜架71之间夹角为零度或接近零度时，此时两安装支架20之间的夹角为90°；当镜腿73旋转至与镜架71之间的夹角为90°时，此时两安装支架20之间的夹角为180°。所以，在扭簧被配置为在镜腿73夹角大于或等于70°后开始产生夹紧力的实施例中，两安装支架20之间的夹角对应为160°，容易理解的，此状态下的镜架71两端的两镜腿73呈相互靠拢状。当然，在两安装支架20之间的夹角还可以取值为170°或140°等，也即，取值为120°至180°之间的钝角皆可。具体的，请一并参照图11至13，图11中两安装支架20均处于折叠位置，图12中两安装支架20均处于适配位置，图13中两安装支架20均处于外翻位置，可以看出，图12中两安装支架20之间 的夹角为钝角，图13中两安装支架20之间的夹角超过180°。
请参照图7至9、16，本实施例中，进一步地，安装支架20包括本体段21和安装段22，安装段22用以与镜腿73或镜架71连接，安装柱24和第一限位槽25均设于本体段21，本体段21还凸设有转轴26，转轴26与安装柱24呈同轴且相背离设置；基座10包括呈相交设置的基板11和安装板12，基板11设有轴孔111，转轴26转动连接于轴孔111，安装板12设有插孔121，扭簧的一安装部32在第一限位槽25内滑动，另一安装部32插设于插孔121。如此，能够方便安装支架20和扭簧安装到基座10上的操作，从而提高生产效率。当然，在其他实施例中，还可以是基座上凸设有转轴，本体段对应转轴设有轴孔；扭簧直接焊接或粘接固定于安装板的表面。
本实施例中，可选地，扭簧的安装部32焊接固定于插孔121。如此，能够提升扭簧的安装可靠性以及工作稳定性。当然，在其他实施例中，还可以是扭簧的安装部插设并粘接固定于插孔，或者是安装部穿过插孔设置，且穿过插孔的部分弯折后抵接于插孔的孔边缘。
请参照图5、7和10，本实施例中，进一步地，安装支架20的本体段21还设有第二限位槽28，所述第二限位槽28沿所述轴孔111的周向延伸，轴孔111的孔边缘对应所述第二限位槽28设有限位凸部112，所述限位凸部112在所述第二限位槽28内滑动。如此，通过限位凸部112与第二限位槽28配合，能够限定出安装支架20相对基座10转动的两个极限位置，也即折叠时的极限位置、以及展开时的极限位置，从而能够避免镜腿73与镜架71的边缘在转动时发生碰撞或干涉，以保护镜腿73与镜架71。
请参照图2和16，本实施例中，可选地，安装段22设有定位孔221和螺钉过孔222，定位孔221用以供镜腿73或镜架71上的定位柱插设，螺钉过孔222用以螺钉锁附于镜腿73或镜架71。当然，在其他实施例中，还可以是安装段通过卡接或粘接或焊接等方式，安装在镜腿或镜架上。
请参照图2、9和10，本实施例中，可选地，安装段22与本体段21之间连接有台阶段23。如此，既能够提升安装支架20的结构强度，又能使安装段22相较于本体段21更贴近镜腿73(或镜架71的)内壁，从而能降低镜腿73或镜架71内壁上凸设的定位柱和螺孔柱的高度，进而提高定位柱和螺孔柱的结构强度，进而提升安装支架20与镜腿73(或镜架71)之间的连接强度。当然， 在其他实施例中，还可以不设置台阶段。
请参照图2至4，本实施例中，进一步地，所述镜腿73连接结构还包括阻尼件51，所述阻尼件51安装于所述基座10，并用以在所述安装支架20相对所述基座10转动时产生阻尼作用。如此，能够使镜腿73在相对镜架71转动时具备阻尼手感，从而提升产品的品质及用户体验，并提升产品市场竞争力。具体而言，本实施例中，安装支架20上的转轴26在基座10上的轴孔111内转动，轴孔111具有相对的两孔边缘，本体段21抵接于轴孔111的一孔边缘，阻尼件51用以使本体段21和轴孔111的孔边缘之间具有相互抵推的趋势，进而增大本体段21与轴孔111的孔边缘之间的动摩擦力，从而能够赋予安装支架20(镜腿73)旋转时的阻尼效果。当然，在其他实施例中，还可以是阻尼件配置为齿轮阻尼器的结构，具体可以是转轴的外周上设有第一齿轮，基座上对应第一齿轮设有第二齿轮，第二齿轮转动连接于基座，第一齿轮啮合连接于第二齿轮；另外，还可以考虑在第一齿轮与第二齿轮之间涂覆阻尼硅脂进一步优化阻尼效果。
请参照图2至4，本实施例中，可选地，阻尼件51具有弹性并呈环状设置，转轴26设有第二螺纹部261，第二螺纹部261穿过轴孔111及阻尼件51，并与第二紧固件42螺纹连接，阻尼件51夹设于第二紧固件42与轴孔111的另一孔边缘之间。具体的，本实施例中，第二螺纹部261为外螺纹柱，第二紧固件42对应设为螺母。如此，通过调节螺母在外螺纹柱上的旋进量，来调节阻尼件51在转轴26的轴线方向上的厚度尺寸，从而调节阻尼件51对安装支架20及基座10所施加的反作用力，进而调节安装支架20相对基座10转动时的动摩擦力，也即，调节阻尼力并使之符合设计要求。同时，能够使量产状态下不同产品的镜腿73旋转阻尼力趋于一致，也即，提升产品的品质一致性，并提升市场竞争力。当然，在其他实施例中，还可以是第二螺纹部为螺纹孔，第二紧固件对应设为螺栓，螺栓的螺柱穿设阻尼件并与螺纹孔连接，阻尼件夹设于螺栓的螺帽与基座之间。
本实施例中，可选地，阻尼件51配置为碟形弹簧。由于蝶形弹簧具有耐磨损、工作稳定可靠的优点，所以能够使阻尼件51所产生的阻尼力维持稳定，并提升使用寿命。当然，在其他实施例中，还可以是阻尼件配置为弹簧垫圈，或弹性硅胶体、弹性橡胶体等。
请参照图3至5，本实施例中，可选地，镜腿73连接结构还包括夹设于碟形弹簧与螺母之间的第一垫圈52、及夹设于碟形弹簧与基板11之间的第二垫圈53。如此，通过第一垫圈52和第二垫圈53来保护碟形弹簧，能够使碟形弹簧更不易磨损，进而保证其工作稳定性，并提升其使用寿命。当然，在其他实施例中，还可以是只设置第一垫圈，或只设置第二垫圈。
请参照图3、7、8和16，本实施例中，进一步地，基板11设有两个轴孔111，两轴孔111的轴线呈相并行且间隔分布设置，其中一轴孔111与一安装支架20转动连接，另一轴孔111与另一安装支架20转动连接。需要说明的是，相并行指的是平行及***行。如此，通过双旋转轴26线的结构，也即，两安装支架20所对应的旋转轴26线具有一定间隔，这能够增大镜腿73连接结构的弯折半径，也即，能够使诸如线束和柔性印刷电路板61等功能件60在跟随镜腿73连接结构弯折时，功能件60被弯折后半径较大，从而便于功能件60在此处的弯折，并使功能件60避免因弯折导致性能显著降低或寿命显著缩短的问题。当然，在其他实施例中，还可以是基板设有一个轴孔，两安装支架上的转轴均转动连接于该轴孔；或者是基板的相对两侧凸设有两个转轴，两个转轴的轴线共线设置，两安装支架分别转动连接于两个转轴。
请参照图2、9至13，本实施例中，进一步地，两所述安装支架20上的转轴26之间还设有传动结构27，所述传动结构27用以使两所述安装支架20的旋转运动互相传递。如此，通过传动结构27能够实现两安装支架20之间的传动，从而使原本由一个安装支架20完成的旋转角度，被两个安装支架20同时旋转完成，例如，假设两安装支架20需要由夹角90°旋转至夹角180°，若只是一个安装支架20完成旋转，则该安装支架20需要相对基座10旋转90°；而本实施例中由于两个安装支架20同时旋转，所以每一安装支架20只需相对基座10旋转45°即可。如此，能够方便对镜腿73折叠和展开的操作，从而提高用户体验。当然，在其他实施例中，还可以不设置传动结构。
请参照9至13，本实施例中，可选地，所述传动结构27包括相互啮合的第一齿部271和第二齿部272，一所述转轴26的外周设有所述第一齿部271，另一所述转轴26的外周设有所述第二齿部272。如此，通过齿轮啮合方式能够提升两安装支架20之间传动的平顺性及稳定性。当然，在其他实施例中，传动结构还可以配置为套设于转轴的弹性胶套，例如橡胶套或硅胶套，两弹性胶套 通过静摩擦力实现抵接滚动，而实现两安装支架的旋转运动互相传递；或者是传动结构配置为皮带，转轴对应皮带设有安装槽，皮带嵌设于安装槽。
请参照图1、16至20，本实施例中，进一步地，头戴显示设备还包括功能件60，功能件60包括线束(附图中未示出)、柔性印刷电路板61和柔性导热件62的其中至少一种，镜架71内设有第一腔72，镜腿73内设有第二腔74，第一腔72与第二腔74相连通，并用以供功能件60穿设；第一腔72的腔口与第二腔74的腔口间隔形成有避让间隙75，避让间隙75位于两安装支架20之间，镜腿73连接结构还包括挡盖80，挡盖80设于避让间隙75。如此，原本会在避让间隙75内显露于外的功能件60，通过挡盖80遮挡该避让间隙75，能够避免用户看到这些功能件60，也即，起到遮丑作用，当然也同时起到了保护功能件60的作用。需要说明的是，分设于镜腿73和镜架71上的不同电子元器件，能够经由线束或柔性印刷电路板61实现电连接，例如镜架71上布置主控电路板，镜腿73上布置电池，电池通过线束或柔性印刷电路板61实现与主控电路板的电连接，也即实现供电及通信。而为了提高头戴显示设备的散热效率，头戴显示设备还会在镜腿73或镜架71上布置均热结构，例如若干散热片，还可以在此基础上增设散热风扇。容易理解的，头戴显示设备在工作时的主要发热源是主控电路板，而主控电路板存在最佳工作温度范围，若其温升后超过该范围，会导致主控电路板的工作性能下降，甚至发生损坏。由于镜腿73或镜架71的内部空间非常有限，但又为了使散热效率能够尽量做好，所以选择将均热结构和主控电路板分设于镜腿73和镜架71上，例如在镜架71上布设主控电路板，两镜腿73上均布设有均热结构。为了使主控电路板上的热量能够更快速地传递给均热结构，在这两者之间连接有柔性导热件62，具体的，柔性导热件62可以是柔性石墨片、柔性石墨烯或导热硅胶等高导热、可多次弯折的零件，也可以是涂覆在柔性印刷电路板61上的诸如导热胶、导热硅脂等的导热材料。由于功能件60均具备柔性，所以在镜腿73连接结构处能够更顺畅地进行弯折，从而提升用户体验。
请参照图16至20，本实施例中，可选地，避让间隙75包括位于镜腿73的外侧的第一间隙751、及位于镜腿73的内侧的第二间隙752，挡盖80包括设于第一间隙751的外挡盖81、及设于第二间隙752的内挡盖82，内挡盖82与外挡盖81呈相对设置。需要说明的是，镜腿73外侧和内侧指的是，当头戴显示设 备佩戴在用户头上后，镜腿73背离用户眼睛的一侧为外侧，朝向用户眼睛的一侧为内侧。如此，通过内挡盖82和外挡盖81能够将镜腿73内、外侧的避让间隙75都遮挡住，从而起到更好的遮丑作用及保护作用。当然，在其他实施例中，还可以是只设置外挡盖，或只设置内挡盖。
请参照图14和15，本实施例中，可选地，内挡盖82通过螺钉锁附于基座10，外挡盖81卡接安装于内挡盖82。如此，利用螺钉锁附能够保证挡盖80与基座10之间的连接强度，而将螺钉设在内挡盖82，并让外挡盖81采用卡接结构安装在内挡盖82，能够避免螺钉在镜腿73外侧显露于外。请参照图18至20，图18和19中镜腿73处于折叠状态，图20中镜腿73处于佩戴状态。容易理解的，当镜腿73处于折叠状态时，用户会很清楚地看到外挡盖81，而看不到内挡盖82，也即，内挡盖82上的螺钉处于藏匿状态，从而能够提升产品的外观品质，进而提升市场竞争力。当然，在其他实施例中，还可以是内挡盖和外挡盖均采用螺钉锁附安装在基座上，或者是内挡盖和外挡盖均采用卡接方式安装在基座上。
请参照图7、8、14、15和20，本实施例中，可选地，基座10的基板11上还设有螺钉孔122和限位孔123，内挡盖82对应螺钉孔122设有让位孔823，并对应限位孔123设有限位柱(附图中未示出)，限位柱插设于限位孔123内，且螺钉穿过让位孔823后锁附在螺钉孔122内。
请参照图16和17，本实施例中，进一步地，内挡盖82的相对两侧缘均设有第一柱面821，镜腿73滑动抵接于一第一柱面821，镜架71滑动抵接于另一第一柱面821；外挡盖81的相对两侧缘均设有第二柱面811，镜腿73滑动抵接于一第二柱面811，镜架71滑动抵接于另一第二柱面811。具体的，本实施例中，第一柱面821为圆柱面，其轴线与相邻的转轴26的轴线呈共线设置，也即内挡盖82的两个侧缘与两个转轴26一一对应，并绕靠近自身的转轴26的轴线弯曲形成有圆柱面，如此，能够使安装在安装支架20上的镜腿73和镜架71，在旋转过程中均能保持与第一柱面821的抵接关系，从而使内挡盖82的遮挡作用和保护作用发挥到极致。而第二柱面811与第一柱面821同理，在此不再一一赘述。当然，在其他实施例中，还可以是第一柱面、第二柱面呈抛物柱面或椭圆柱面设置。
请参照图14至17，本实施例中，进一步地，内挡盖82的相对两侧缘均设 有第一缺口822，第一缺口822用以供功能件60穿设；外挡盖81的相对两侧缘均设有第二缺口812，第二缺口812用以供功能件60穿设。也即，在第一柱面821上开设第一缺口822，并在第二柱面811上开设第二缺口812，能够增大供功能件60穿设的内部空间，从而使功能件60能够顺畅地展开和弯折，不会受到干扰阻碍。
请参照图1、16至20，本申请还提出一种头戴显示设备，包括镜腿73、镜架71、及前述的镜腿73连接结构，该镜腿73连接结构的具体结构参照上述实施例，由于本头戴显示设备采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。其中，镜腿73连接结构的一安装支架20与镜腿73连接，另一安装支架20与镜架71连接。
