请参阅图1至图5，本发明实施方式的头戴显示装置1000，可以是虚拟现实装置，用于进行视频播放、游戏等功能。头戴显示装置1000包括有耳机装置100和显示装置200。其中，耳机装置100包括有卡座，卡座10形成有收容腔，卡座10的侧壁11开设有安装孔12，侧壁11包括有相背的内表面11a和外表面11b。显示装置200包括连接组件20，连接组件20能够拆卸安装在卡座10上，连接组件20包括基座21、卡杆22、施力件23和按钮24。基座21的一端能够伸入安装孔12并与安装孔12一端的内表面11a卡合。卡杆22、施力件23和按钮24联动的安装在基座21上，施力件23与卡杆22接触并对卡杆22施加一压力，卡杆22的一端能伸入安装孔12内并在该压力的作用下 与安装孔12另一端的内表面11a卡合。显示装置200还包括未示出的镜片模组、电路及电池等相关元件。在耳机装置100和显示装置200连接时，耳机装置100和显示装置200可协同工作，为用户同时视频与音频。在耳机装置100和显示装置200分离时，耳机模组100可以通过卡座或连接线与其他显示设备连接，显示装置200也可与其他音频设备通过连接组件或通过无线方式相连接。
可以理解地，可拆卸连接使得耳机装置100和显示装置200均可以独立使用，降低了头戴显示设备1000损坏的成本，用户也可根据个人需求对头戴显示设备1000进行扩展或升级，例如，对音质需求较高的用户，可自行更换耳机装置100，又如，显示装置200产品更新后，用户也可单独对该部分组件进行更换。相类似地，头戴显示设备1000发生故障后，可分体进行维修或更换，降低了维护成本。
此外，可拆卸连接丰富用户的使用场景，满足用户使用的需求，用户可以单独使用其中任意一个组件，并且由于分体设计，佩戴更加轻便舒适。
请参阅图2至图5，在某些实施方式中，卡杆22伸入安装孔12并与安装孔12一端内表面11a卡合的端部22a在按压按钮24时朝接近基座21的中心轴方向运动以使得连接组件20能够从安装孔12中退出，端部22a在松开按钮24时朝远离所述基座21的中心轴方向运动以与安装孔12的另一端的内表面11a卡合。
具体地，卡杆22的包括两端部22a和22b，其中端部22a伸入安装孔12与安装孔12进行卡合，另一端部22b与按钮24相接触，当对按钮24施加作用力时，按钮24对端部22b施加作用力，通过卡杆作用使得端部22a具有向该作用力相反方向运动的趋势，也即是说，在按压按钮24时，当作用力大于施力件23对端部22a的作用力时，端部22a朝向基座21的中心轴运动，使得连接组件20能够从安装孔12中退出，而未对按钮24施加作用力或按钮24的作用力撤销时，由于施力件23对端部22a具有作用力，该作用力大于按钮 24施加的作用力时，端部22a朝向远离基座21的中心轴的方向运动以在伸入安装孔12时可以与安装孔12卡合。
在某些实施方式中，基座21能够伸入安装孔12的一端为卡合端，基座21包括本体21a和自本体21a的外侧壁延伸的卡合块21b，卡合块21b位于卡合端的一侧，当基座21伸入安装孔12内时，卡合块21b能与内表面11a卡合。
可以理解地，当连接组件20与卡座10卡合时，卡合块21b到端部22a的水平距离应当大于安装孔12两端部的水平距离，因此，在安装或拆卸时，应当使可活动的端部22a首先向基座21a的中心轴方向运动，并使得卡合块21b首先卡入安装孔12，而后再使得端部22a与安装孔12卡合。
进一步地，在这样的实施方式中，本体21a包括顶面21c，顶面21c设置有轨道21d，卡杆22包括能伸入安装孔12内的卡接端22a和与卡接端22a相对的抵触端22b，顶面21c上设置有枢轴21e，卡杆22通过枢轴21e可转动地安装在顶面21c上，卡接端22a与抵触端22b分布在枢轴21e两端，施力件23的一端23a与基座21抵触，另一端23b与卡杆22抵触，按钮24能够移动地穿设在轨道21d内，抵触端22b与轨道21d对应，当按压按钮24时，按钮24伸出轨道21d并推动抵触端22b以带动卡接端22a绕枢轴21e朝接近基座21的中心轴方向转动。
具体地，枢轴21d作为卡杆22转动的支点，卡杆22可转动的安装在枢轴21e上，也可以开设卡口与枢轴21e卡接并绕轴转动。卡接端22a也即是伸入安装孔12与安装孔12进行卡合的端部22a，抵触端22b也即是与按钮24相接触的端部22b。轨道21d则限定了按钮24的施力及移动方向，操作中，对按钮24的一端施力，按钮24可沿轨道21d所限定的方向移动以对抵触端22b施力。
进一步地，在某些实施方式中，基座21还包括自顶面21c延伸的凸台21f，凸台21f包括上表面210、第一侧面211和与第一侧面211相背的第二侧面212，第一侧面211与第二侧面212与上表面210和顶面21c均连接，上表面210 开设有凹槽以形成轨道21d，凹槽贯穿第一侧面211与第二侧面212，按钮24包括按压端24a、抵接端24b和连接在按压端24a与抵接端24b之间的杆体24c，杆体24c收容在凹槽内，按压端24a与抵接端24b分别位于凹槽外并分别与第一侧面211与第二侧面212相对。
可以理解地，按压端24a和抵触端24b的横截面积均大于轨道21d的横截面积，以使得按钮24可以卡入轨道21d中，而不会在施力状态下从轨道21d中滑脱。
进一步地，按钮24的最大移动行程为杆体24c的长度与凹槽的长度之差。
如此，按钮24可在施力状态下在轨道内产生位移以对卡杆22施力，需要说明的是，杆体24c能产生的位移应当使得卡接端22a在受力时足够从安装孔12中伸入以进行卡合或从安装孔12中退出。
进一步地，在某些实施方式中，抵触端22b包括抵触面220，抵触面220开设有缺口220a，卡接端22a与内表面11a卡合时，抵触面220与第二侧面212抵触，抵接端22b位于缺口220a内。
进一步地，在某些实施方式中，抵触面220与第二侧面212为面接触。
具体地，抵触端22b与抵接端24b也为面接触，从而增大受力面积，方便按键24对卡杆22施力。缺口220a一方面作为受力端以方便用于容纳抵接端24b，使得各机构之间的排布更合理。
进一步地，在某些实施方式中，施力件23位于凸台21f与卡杆22之间，施力件23为弹性件，弹性件的一端与凸台21f固定连接或抵触，弹性件的另一端与卡杆22固定连接或抵触。
具体地，操作过程中，对按钮24施力，卡接端22a向基座21的中心轴方向运动对弹性件产生压力，弹性件处于受压状态，当松开按钮24时，弹性件由受压状态回复，驱动卡接端22a向远离基座21中心轴方向运动以与安装孔12卡合。弹性件与凸台21f及卡杆22的连接关系可包括两端分别相抵触、两端分别固定连接以及一端抵触一端固定连接，在此不做限制。
在一些示例中，基座21还包括自顶面21c延伸的固定件21g，固定件21g位于凸台21f与卡杆22之间，施力件23为扭簧，扭簧套设在固定件21g上，扭簧的一端与凸台21f抵触，扭簧的另一端与卡杆22抵触。
在另一些示例中，施力件23还可以弹簧，相类似的，弹簧的一端与凸台21f抵触，另一端与卡杆22相抵触。
在某些实施方式中，内表面11a靠近安装孔12的一侧沿接近安装孔12的方向形成朝收容腔凸出的倾斜段12a，倾斜段12a逐渐向接近收容腔内部倾斜，卡接端22a包括与倾斜段对应的倾斜的卡接面，卡接端22a伸入安装孔12时，卡接面与内表面11a的倾斜段12a卡合。
可以理解地，内表面11a呈圆弧状，倾斜段12a的形状与卡接面相配合，例如可以是矩形面，如此，可使得卡接端22a与内表面11a卡合的更加牢固。当然，在一些示例中，也可将卡接端22a做成圆弧状以与内表面11a相配合。
在本说明书的描述中，参考术语“一个实施方式”、“某些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合所述实施方式或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施方式，本领域的普通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施方式进行多种变化、修改、替换和变型，本发明的范围由权利要求及其等同物限定。
