本发明提供了一种可拆卸的连接结构，可以实现两个部件间的快速 装配、快速拆卸。本发明的连接结构可以应用到各产品中，例如可应用到智能穿戴领域。为了便于描述本发明的连接结构，现以AR眼镜为例，对本发明连接结构的构造以及快拆原理进行详尽的描述。但需要注意的是，本发明的连接结构不但可以应用到可穿戴设备中，还可应用到其它需要快速锁定、快速拆卸的装置中，在此不再一一列举。
图1示出了本发明AR眼镜的爆炸示意图，其包括眼镜主体1以及通过本发明连接结构装配在眼镜主体1上的光机结构2。
具体地，参考图1、图2，本发明的连接结构包括具有内腔的壳体4，以及从壳体4开口端伸入到壳体4内腔中的柱塞8以及铰链机构5。壳体4具有一端开口的内腔，其横截面可以呈圆形，也可以呈方形或者本领域技术人员所熟知的其它形状。
壳体4可固定在眼镜主体1上，例如可通过一体注塑的方式形成在眼镜主体1的支架腿3上。柱塞8可固定安装在光机结构2上，使得光机结构2可通过柱塞8与壳体4的配合与眼镜主体1装配在一起。当然，对于本领域的技术人员而言，壳体4也可以固定在光机结构2上，柱塞8固定在眼镜主体1上，在此不再具体说明。
图6示出了本发明铰链机构5的结构示意图，其包括通过弹性装置6预压在壳体4内腔中的铰接本体50，以及铰接在铰接本体50上的铰接部51。
在本发明一个具体的实施方式中，铰接本体50可以呈板状，其可通过设置的导向槽或者本领域技术人员所熟知的其它的导向机构沿壳体4内腔轴向滑动配合在壳体4的内腔中。铰接部51可以设置有两个，该两个铰接部51可分别通过铰接轴(视图未给出)安装在铰接本体50相对的两侧，使得铰接部51可以相对于铰接本体50发生偏转。由于铰接部51位于交接本体50相对的两侧，当处于关闭状态时，两个铰接部51形成了可夹持柱塞8的空间；当两个铰接部51向各自的外侧方向偏转时，则两个铰接部51处于打开状态，从而可以将释放后的柱塞8取出。
参考图2，为了使铰链机构5与柱塞8更好地配合在一起，在铰接部51的内壁上设置有向内延伸的凸缘510，对应地，柱塞8的外壁上设置 有用于与凸缘510配合在一起的凹槽80。本发明的柱塞8可以呈圆柱状或者锥台状。凹槽80设置在柱塞8的外壁上，当其伸入到两个铰接部51之间的位置时，两个铰接部51向内进行偏转，使得两个铰接部51的凸缘510可以卡入柱塞8的凹槽80中，从而实现了两个铰接部51对柱塞8的稳固夹持。
在本发明另一个具体的实施方式中，铰接本体50也可以呈柱状结构或者筒状结构，且铰接本体50的形状与壳体内腔的形状相匹配，使得铰接本体50可以在壳体内腔中滑动。铰接部51可以设置有至少三个，这些铰接部51可以间隔地分布在铰接本体50的周向方向上，共同围成了用于夹持柱塞8的空间。为了使铰接部51与柱塞8紧密配合在一起，铰接部51围成的空间形状与柱塞8的形状相匹配。例如当柱塞8采用圆柱形时，则多个铰接部51围成了圆形的收容空间。
另外，无论铰接本体50采用板状结构还是采用柱状结构，铰接部51可以选用平板状的结构或者圆弧状的结构。为了使铰接部51更好地将柱塞8夹持住，优选使铰接部51的内壁与柱塞8外壁的形状相匹配。例如当柱塞8采用圆柱形结构时，则铰接部51的内壁、凸缘510的内壁采用与其相配的圆弧面。这属于本领域技术人员的公知常识，在此不再具体说明。
图4示出了铰链机构5在壳体4内的装配图，本发明的铰链机构5装配在壳体4的内腔中，并在柱塞8的驱动下可在壳体4的内腔中具有一定的运动行程。在铰链机构5伸入到壳体4内腔的过程中，壳体4的开口端位置会挤压铰接部51使其向内发生偏转，且壳体4的内壁会使铰接部51一直保持在关闭状态；当铰接部51被拉出壳体4内腔后，此时铰接部51不再受到壳体4内壁的限制，使得铰接部51可以向外打开。
弹性装置6设置在铰接本体50与壳体4之间，使得铰链机构5可以被预压在壳体4内腔中，并且当按压铰链机构5的力撤销后，弹性装置6在其自身弹性恢复力的作用下可以将铰链机构5弹起。该弹性装置6可以选用本领域技术人员所熟知的弹簧、卡簧或者拉簧的结构，这属于本领域技术人员的公知常识，在此不再具体说明。
初始位置时，铰链机构5的铰接部51位于壳体4的内腔外，且处于 被打开的状态；柱塞8在伸入到壳体4内腔的过程中推动铰接本体50并挤压弹性装置6向壳体4内腔中运动；当铰接部51运动至壳体4开口端的位置时，铰接部51在壳体4开口端的挤压下向柱塞8的方向偏转，从而使得铰接部51的凸缘510与柱塞8的凹槽80配合在一起；当铰接部51运动至壳体4内腔中后，由于铰接部51与壳体4内壁配合在一起，此时无法打开铰接部51，从而使得铰接部51可以与柱塞8保持连接在一起。
优选的是，为了便于柱塞8与铰接本体50的配合，柱塞8的端头采用圆台状或圆锥状结构。
当需要拆卸时，只需要将柱塞8向外拔出，由于铰接部51的凸缘与柱塞8的凹槽配合在一起，因此铰链机构5整体会与柱塞8同步朝壳体4外运动；当铰接部51从壳体4的内腔中完全脱离后，使铰接部51往各自的外侧方向偏转，从而实现了铰接部51与柱塞8的脱离。
在本发明一个优选的实施方式中，铰接部51上凸缘510与柱塞8上凹槽80的配合面为使铰接部51朝打开方向偏转的斜面。例如凸缘510上与凹槽80在径向方向上的接触面为斜面，和/或凹槽80上与凸缘510在径向方向上的接触面为斜面。
当铰接部51位于壳体4内腔中时，虽然在抽取柱塞8的过程中，柱塞8会为铰接部51提供一个向外打开的力，但是壳体4的内壁会阻挡铰接部51发生偏转；当铰接部51从壳体4内腔中脱离后，柱塞8会推动铰接部51向外侧偏转，使得铰接部51可以自动打开，实现铰接部51与柱塞8的自动分离、拆卸。
在本发明一个具体的实施方式中，为了防止铰链机构5从壳体4内腔中完全脱出，可以设置止挡部件，以将铰链机构5限制在壳体4内腔中，也就是说，限制铰链机构5在壳体4内腔中的行程。这种止挡部件的设置属于本领域技术人员的公知常识，在此不再具体说明。
铰链机构5的外壁与壳体4的内壁可以设置成过盈配合方式，例如铰链机构5的外壁可以设置成楔形结构，其越往壳体4内腔中伸入，铰链机构5的外壁与壳体4内壁配合的就越紧，从而可以保证当柱塞8装配到位后，需要借助较大的外力才能将柱塞8与铰链机构5从壳体4内腔中抽 出，以保证柱塞8连接的稳固性。
在本发明另一个具体的实施方式中，设置有档位结构，档位结构被配置为：在铰接本体50被弹性装置6弹起以及预压在壳体4内腔的过程中，档位结构在锁止铰接本体50第一位置以及第二位置间循环切换。
当铰接本体50被弹起装置6时，档位结构可以与铰接本体50的第一位置锁止在一起，以防止铰接本体50从壳体4内腔中脱出。当铰接本体50被预压在壳体4内腔中，此时铰接部51位于壳体4内腔中，也就是说，此时柱塞8被铰接部51夹持在壳体4的内腔中。档位结构可以将该状态时的铰接本体50的第二位置锁止住，从而防止柱塞8的自动脱出。
实现上述功能的档位结构可以采用本领域技术人员所熟知的机构，例如圆珠笔或者中性笔中通过按压实现笔头弹出、缩回的转换机构。这种笔的转换机构使得仅通过按压便可实现笔头在两种状态下的循环切换。
在本发明一个优选的实施方式中，档位结构采用如下的方式：
为了便于描述，现以壳体4内腔的轴向方向记为Y轴方向，以垂直Y轴的方向记为X轴方向。
档位结构包括档位块7，档位块7被配置为相对于壳体4在X轴方向上滑动。例如档位块7导向配合在壳体4的内壁中，使得档位块7可以在壳体4的内壁中延伸X轴方向滑动。
在此需要注意到是，此处指的X轴方向可以是直线运动，也可以是曲线运动。例如当壳体4为圆筒状结构时，则档位块7被配置为在壳体4的部分圆周方向上往复运动。当壳体4采用矩形结构时，则档位块7被配置为在壳体4的其中一侧内壁上直线运动。
在本发明一个优选的实施方式中，参考图3，在壳体4的内腔中设置有一支架板40，支架板40沿壳体4内腔的轴向方向进行装配。档位块7可以通过本领域技术人员所熟知的导向槽或者导轨结构滑动配合在支架板40上。
档位结构还包括位于铰接本体50上且用于推动档位块7在X轴方向上的运动的档位槽52，参考图4、图5、图6。档位块7的一部分滑动配合在支架板40上，另一端与铰接本体50上设置的档位槽52配合在一起，使 得铰接本体50在壳体4内腔中沿Y轴方向运动时，通过档位槽52不同位置与档位块7的配合，从而可以推动档位块7在支架板40上沿着X轴方向往复运动。
具体地，参考图5，档位块7包括滑动块70、凸起柱71，二者可以是一体成型的。滑动块70设置在支架板40上的滑动槽中，使得滑动块70可以在支架板40的滑动槽中沿X轴方向往复运动。凸起柱71可以垂直地连接在滑动块70的端面上，其从支架板40的滑动槽中伸入，并与铰接本体50上的档位槽52配合在一起。
其中，档位槽52具有位于第一位置且用于与档位块7配合在一起的第一锁止拐点A，以及位于第二位置且用于与档位块7配合在一起的第二锁止拐点C。当初始位置时，档位块7与第一锁止拐点A配合在一起，从而可以防止铰接本体50从壳体4内腔中脱出。
当处于装配的锁定位置时，档位块7与第二锁止拐点C配合在一起，可以防止柱塞8、铰接部51从壳体4内腔中脱出。而且此时在弹性装置6的预压作用力下，需要克服弹性装置6的反作用力才可以将柱塞、铰链机构5往壳体4内腔中继续推进。
档位槽52可以是在铰接本体50侧壁上形成的内凹结构，也可以是在铰接本体50侧壁上由凸起结构围成，在此不做限定。
具体地，参考图7，档位槽52近似呈心形结构。以第一锁止拐点A记为XY轴的坐标原点，档位槽52从第一锁止拐点A开始依次包括朝X轴正向以逐渐接近壳体4开口端的方式延伸的第一内壁521，朝X轴负向以逐渐接近壳体4开口端的方式延伸的第二内壁522，朝X轴负向上以逐渐远离壳体4开口端的方式延伸的第三内壁523，朝X轴负向以逐渐接近壳体4开口端的方式延伸的第四内壁524，朝X轴负向上以逐渐远离壳体5开口端的方式延伸的第五内壁525，朝X轴正向以逐渐远离壳体4开口端的方式延伸至第一锁止拐点A的第六内壁526。
第一内壁521与第二内壁522之间形成了拐点B1，第二内壁522与第三内壁523之间形成了拐点B，第三内壁523与第四内壁524之间形成了拐点D，第四内壁524与第五内壁525之间形成了拐点E，第五内壁525 与第六内壁526之间形成了拐点E1，第六内壁526与第一内壁521之间形成了第一锁止拐点A。
这六个内壁可以为连接在一起的六个直线段，或者是连接在一起且平滑过渡的曲线。
在所述档位槽52中设置有凸起的延伸部，延伸部包括形成第二锁止拐点C的第一延伸部527、第二延伸部528，第一延伸部527从第二锁止拐点C开始朝X轴正向以逐渐接近壳体4开口端的方式延伸；第二延伸部528从第二锁止拐点C开始朝X轴负向以逐渐接近壳体4开口端的方式延伸。也就是说，两个延伸部在X轴的两个方向上分别以逐渐接近壳体4开口端的方向延伸，使得两个延伸部近似呈L形或者C形。
由于延伸部设置在档位槽52内，因此第一延伸部527与第二延伸部528连接位置形成的第二锁止拐点C位于第一锁止拐点A以及拐点D之间的位置。
在本发明一个具体的实施方式中，第二锁止拐点C在X轴上的正投影相对于第一锁止拐点A(坐标原点)位于X轴负向上。参考图7的视图方向，第二锁止拐点C位于第一锁止拐点A左上方，使得在Y轴方向上，第一延伸部527与第一锁止拐点A正对。
当位于初始位置时，弹性装置6处于弹起状态，铰接部51位于壳体4内腔外，铰接本体50可以全部或者部分地位于壳体4的内腔中。此时档位块7与第一锁止拐点A的位置配合在一起。
由于档位块7只能在X轴方向运动，而无法在Y轴方向上运动。当档位块7位于第一锁止拐点A的位置时，可以阻挡铰链机构5在Y轴的正方向(朝壳体4开口端的方向)上运动，使得铰链机构5无法从壳体4中完全脱出。
当需要装配的时候，将柱塞8插入多个铰接部51之间的位置，使得柱塞8与铰接本体50配合在一起，并推动铰接本体50预压弹性装置6往壳体4的内腔中运动。
此时，由于第一延伸部527与第一锁止拐点A正对，在柱塞8、铰接部51、铰接本体50整体沿Y轴负向(往壳体4内腔的方向)运动的过 程中，第一延伸部527的侧壁会首先与档位块7接触配合在一起。且由于第一延伸部527朝X轴正向以逐渐接近壳体4开口端的方式延伸，使得第一延伸部527的外壁会挤压档位块7沿X轴正向运动。
当第一延伸部527驱动档位块7沿X轴正向运动至越过第一延伸部527的端头后，档位块7与第一延伸部527脱离，且停止在X轴方向上的运动。
在铰接本体50持续沿Y轴负向运动的过程中(铰接本体50往壳体4内腔中持续伸入的过程中)，档位槽52的第二内壁522会与档位块7接触配合在一起。且由于第二内壁522朝X轴负向以逐渐接近壳体4开口端的方式延伸，因此在铰接本体50持续往壳体4内腔中运动时，第二内壁522会挤压档位块7朝X轴负向运动，直至使档位块7移动至第一延伸部527的上方。此时可松开柱塞8，使得铰接本体50在弹性装置的作用下顶起，当第一延伸部527在沿Y轴正向被顶起时，其内壁可以推动档位块7沿X轴负向运动至第二锁止拐点C的位置。此时，铰接部51收容在壳体4内腔中，且将柱塞8夹持住，完成柱塞8与壳体4的装配。
当然，对于用户而言，在装配的时候无法看到档位块7是何时移动至第一延伸部527上方，因此用户无法决定撤销按压力的时机。为了解决这个问题，在档位槽52中设置了拐点B，且拐点B的位置与第一延伸部527在Y轴方向上正对。
由于形成拐点B的第二内壁522与第三内壁523的倾斜方向相反，因此当第二内壁522朝向Y轴负向运动，直至使拐点B的位置与档位块7配合在一起时，拐点B构成了阻挡铰链机构5在Y轴负方向上继续运动的止挡部。
此时对于用户而言，当档位块7与拐点B配合在一起时，便无法再推动柱塞8往壳体4内腔中运动。因此拐点B的位置可以作为柱塞8装配时的下止点，此时用户就可以撤销按压的力，并按照上文描述的方式使弹性装置6将铰接本体50顶起，最终使档位块7与第二锁止拐点C配合在一起，完成柱塞8的装配。当需要拆卸的时候，下压柱塞8，使得柱塞8推动铰接本体50沿Y轴负向运动，直至第四内壁524与档位块7接触配合在一起。 为了保证第四内壁524可以与档位块7配合在一起，配置使第二锁止拐点C与第四内壁524在Y轴方向上正对。
由于第四内壁524朝X轴负向以逐渐接近壳体4开口端的方式延伸，因此在铰接本体50沿Y轴负向运动时，第四内壁524会推动档位块7沿X轴负向运动。
当第四内壁524驱动档位块7沿X轴负向运动至越过第二延伸部528的端头后，此时可松开柱塞8，弹性装置6将铰接本体50顶起，使得在铰接本体50沿着Y轴正向运动的过程中，第五内壁525、第六内壁526可以推动档位块7沿X轴正向移动至第一锁止拐点A的位置。此时，铰接部51从壳体4内腔中脱出，完成柱塞8的拆卸。
当然，对于用户而言，在拆卸的时候无法看到档位块7何时越过第二延伸部528的端头，因此用户无法决定撤销按压力的时机。为了解决这个问题，在档位槽52中设置了拐点E，且要保证当拐点E与档位块7配合在一起时，档位块7已经越过了第二延伸部528的端头。例如参考图7的视图方向，拐点E位于第二延伸部528的端头的左侧。
由于形成拐点E的第四内壁524与第五内壁525的倾斜方向相反，因此当第四内壁524朝向Y轴负向运动，直至使拐点E的位置与档位块7配合在一起时，拐点E构成了阻挡铰链机构5在Y轴负方向上继续运动的止挡部。
此时对于用户而言，当档位块7与拐点E配合在一起时，便无法再推动柱塞8往壳体4内腔中运动。因此拐点E的位置可以作为柱塞8拆卸时的下止点，此时用户就可以撤销按压的力，并按照上文描述的方式使弹性装置6将铰接本体50顶起，最终使档位块7与第一锁止拐点A配合在一起，完成柱塞8的拆卸。
对于用户而言，在装配的时候，只需要将柱塞8插入铰接部51之间的位置并推动铰接本体50运动至装配时的下止点即可松手，通过弹性装置6的弹性恢复力自动装配到位。在拆卸的时候，只需要推动柱塞运动至拆卸时的下止点即可松手，通过弹性装置6的弹性恢复力自动拆卸。采用本发明的连接结构，不但装配稳定，而且拐点B、拐点E为用户提供了装配、 拆卸时的力反馈点，用户只需要分别通过一次推动的动作即可实现柱塞的装配、拆卸，操作及其便捷。
在本发明一个优选的实施方式中，参考图7的视图方向，也可以配置为：在拆卸的时候，当第四内壁524推动档位块7沿X轴负向运动至越过第二延伸部528的端头时，如果此时档位块7位于第六内壁526的正上方，当弹性装置6将铰接本体50顶起时，第六内壁526会直接与档位块7配合在一起，并将其推至第一锁止拐点A的位置，而不用经过第五内壁。
因此，拐点E1不是必须的，这就使得第五内壁、第六内壁可以是平滑过渡的弧形曲线，而并不一定要形成拐点E1。基于同样的道理，第一内壁、第二内壁也可以是平滑过渡的弧形曲线，并不一定要形成拐点B1。
上述的实施例中，在档位槽52沿Y轴方向运动的过程中，档位块7是沿着逆时针方向围绕档位槽52运动的。当然也可以通过配置，使得档位块7沿着顺时针方向围绕档位槽52运动。当铰链机构5沿Y轴负方向运动时，只需要设置使第二延伸部528的外壁首先与位于第一锁止拐点A的档位块7配合在一起，例如使得在Y轴方向上，第一锁止拐点A与第二延伸部528的外壁正对即可。此时，所述第二锁止拐点C与第三内壁523正对，使得在解锁时，档位块7会离开第二锁止拐点C并与第三内壁523配合在一起，以完成解锁的动作。该解锁、闭锁的动作与上述实施例的原理类似，在此不再具体说明。
本发明的AR眼镜，光机结构2通过上述的连接结构装配在眼镜主体上，至需要通过按压即可实现光机结构2与眼镜主体的装配以及拆卸，提高了AR眼镜的可拆卸性。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
