作为优选的实施例，如图1至3所示，第一连接部22包括形成于轴体21上的固定孔，固定孔用于供第一车体上的转轴固定台12伸入。应当理解，固定孔设置在转轴位于第一车体的部分上，当然固定孔可以设置在轴体21的一侧或者轴体21的上下两侧均设置。在一个实施例中，固定孔为贯穿轴体21的通孔，第一车体分为上壳体和下壳体，轴体21上方的固定孔与上壳体中的转轴固定台12配合，轴体21下方的固定孔与下壳体中的转轴固定台12配合，以使轴体21紧固在第一车体中。其中固定孔和转轴固定台12的数量可以为一个，也可以为两个，均设置在相应的转轴位于第一车体的部分上。
需要说明的是，第一连接部22还可以为形成于轴体21端部上的凸出柱，并与第一车体上的转轴固定槽配合连接。当然，第一连接部22还可以为其他形式，只要能将轴体21固定至第一车体上即可。
作为优选的实施例，如图1-3所示，第二连接部23包括形成于轴体21上并且位于轴承40两侧的卡簧槽。如图4所示，卡簧槽用于安装卡簧50，轴承40卡设在两个卡簧50之间，卡簧50用于固定轴承40，限制轴承40在 轴体21上移动。其中轴承的数量可以为一个也可以为两个或更多，相应的卡簧及卡簧槽对应轴承的数量配置。
如图1-3所示，在一个实施例中，限位部24包括由轴体21第二连接部23的端部延伸形成的限位台24-1，和/或沿轴体21径向开设的限位槽24-2。应当理解的是，限位台24-1和限位槽24-2设置在具有轴承40的一侧轴体21上，用于当第一车体带着轴体21相对于轴承转动或第二车体带着轴承相对于轴体21转动至预定角度时，限位台24-1或限位槽24-2的抵接平面与配合部的抵接平面接触时，限制第一车体或第二车体的继续转动。
其中，轴体21的具有凸出的限位台24-1，具体形状为从转轴端部切削形成的半圆台，半圆台具有两个截面，半圆台的两个截面形成第一抵接平面，配合部30具有第二抵接平面，限位台24-1的第一抵接平面与第二车体上配合部30的第二抵接平面配合，当第一车体或第二车体转动至预定角度时，第一抵接平面与第二抵接平面接触，限制第一车体或第二车体的继续转动，使得轴体21转动范围不会过大，减少误操控。当第二车体旋转时，第二车体与轴承40相对于轴体21旋转；当第一车体旋转时，第一车体与轴体21相对于轴承旋转。
其中，轴体21右侧沿垂直于轴线方向凹陷形成限位槽24-2，即限位槽24-2为沿轴体21径向开设形成，内部为中空结构的转轴在沿径向开槽之后必然在槽的两端具有两个截面，即限位槽具有两个截面，且限位槽的两个截面形成第一抵接平面，配合部具有第二抵接平面，限位槽24-2的第一抵接平面与第二车体上配合部30的第二抵接平面配合，当第一车体或第二车体转动至预定角度时，第一抵接平面与第二抵接平面接触，限制第一车体或第二车体的继续转动，使得轴体21转动范围不会过大，减少误操控。限位槽24-2 可以设置在转轴20对应第二车体的部分，但不与轴承40产生干涉，相对应的设置限位部(钢片)与限位槽配合，并在相应的在车体上设置限位钢片的容纳槽。
如图5至9所示，本实施例还提供了一种平衡车组件，包括两个车体10，安装于车体10上的配合部30，以及安装于两个车体10上的转轴20，其中,转轴20为上述的平衡车转轴。
关于第一车体和第二车体，参照附图5，其中第一车***于左侧，第二车***于右侧。需要说明的是，第一车体和第二车体的位置可以调换，即第一车***于右侧，第二车***于左侧。
需要注意的是，在本实施例中，当第二车体旋转时，第二车体与轴承40相对于轴体21旋转；当第一车体旋转时，第一车体与轴体21相对于轴承40旋转。当第一车体或第二车体发生转动并转动至预定角度时，限位部24与配合部30抵接，限制第一车体或第二车体的继续转动，防止转动角度过大，提升安全性能，增加转动的灵活度，并且简化了安装复杂度，节约了成本。
参考图6，第一车体和第二车体上均设有转轴槽11，第二车体上设有容纳轴承40的轴承槽15，第一车体上还设有抵接轴体21端面的阻挡板13，第二车体上设有用于固定穿过轴体21的线束的线束固定扣14。转轴槽11内设置有转轴固定台12，转轴固定台12与固定孔(即第一连接部22)配合连接，其中，转轴固定台的数量可以根据转轴上固定孔的数量设置，轴承槽的数量根据转轴上轴承的数量设置。
转轴固定台12设置在第一车体上的转轴槽11中，用来在第一车体上固定转轴20，阻挡板13设置在第一车体上的转轴槽11的左端部与转轴20左侧端面抵接，阻挡板13与转轴固定台12配合使得转轴20不会产生移动。转 轴固定台12可以为硬质塑料等，转轴20在长期使用的情况下会磨损或者破坏固定台，阻挡板13可以防止转轴20对转轴固定台12的损坏，为了加强转轴固定台12的强度，可以在转轴固定台12上穿入螺丝等部件。当然也可以同时或者单独在第二车体上设置阻挡板，防止转轴的移动。轴承槽15设置在第二车体上的转轴槽11中(也可以说设置在第二车体上的转轴槽11的右端部)，用来放置轴承40。限位支撑柱31设置在轴承槽15右端部。线束固定扣14设置在第二车体上，用来固定穿过转轴20的线束，防止转轴20端面口在转动时与线束摩擦而损坏线束，该线束可以用来供电，传递信号等。当然线束的固定也可以采用胶带等方式固定在第二车体上，也可以在第一车体上设置线束固定的结构。第一车体上的转轴槽11与第二车体上的转轴槽11相对的一侧需要与转轴20配合紧凑，防止转轴20的松动造成异响、降低驾驶体验。
如图7所示，在一个具体实施例中，转轴20上设有一个轴承40，第二车体上设有容纳轴承40的轴承槽。轴承槽设置在第二车体的转轴槽11中或者说轴承槽设置在第二车体的转轴槽11的右端部，用于放置轴承。为了使轴承40在转轴上不滑动，轴承的两侧设有卡簧40，将轴承40固定在转轴上且位于轴承槽中，转轴上设有容纳卡簧的卡簧槽。
在一个具体实施例中，转轴20上设有两个轴承40，第二车体上设有两个容纳轴承40的轴承槽。在转轴20的右侧设置两个轴承40，增加转动稳定性；且每个轴承40都具有相应的轴承槽以放置轴承40。为了使轴承40在转轴上不滑动，每个轴承40的两侧均设有卡簧50，将轴承40套设在转轴上且位于轴承槽中，转轴上设有容纳卡簧50的卡簧槽。
其中，在一个实施例中，限位部24包括由轴体具有第二连接部的端部延 伸形成的限位台24-1，配合部30包括第一限位板36，第一限位板36具有与限位台24-1配合的抵接平面，当然可根据需要在第一限位板36上同时设置弧形槽口，如图7所示。其中弧形槽口用于通过线束。应当理解的是，限位台24-1设置在转轴的右侧部分，即限位台24-1设置在具有轴承的一侧转轴上，转轴上的限位台24-1具有第一抵接平面，配合部的第二限位板具有第二抵接平面，当第二车体带着轴承相对于转轴转动至预定角度时，第一抵接平面与第二抵接平面接触，限制第二车体的继续转动。
具体地，第一限位板36设置于右车体10下壳的容纳槽中，为金属片状。第一限位板36的接触面(抵接平面)与转轴上的限位台24-1的截面对齐，当转轴20转动时限位台24-1截面与第一限位板36的接触面接触时，达到限位的效果，并减轻限位台24-1对于容纳槽的损坏。第一限位板36设置在转轴20右端口处，具有两个截面，用来限位顺时针和逆时针的转动。
在又一个实施例中，限位部24包括由轴体21具有第二连接部23的端部延伸形成的限位台24-1，即限位台设置在第二连接部的端部延伸形成的限位台24-1，配合部30包括限位支撑柱31，限位支撑柱31具有与限位台配合的抵接平面，如图8所示。具体地，限制支撑柱具有两个，两个限位支撑柱的端面为限位端，两个限位端形成抵接平面(第二抵接平面)且与限位台的端面(第一抵接平面)配合，以限制第一车体或第二车体的转动范围。更优选地，限位支撑柱上设有螺钉32，螺钉的端面(螺帽)为与限位台配合的抵接平面。螺帽与限位台24-1截面接触时达到限位效果，并减轻限位台对于限位支撑柱的损坏，起到加强限位支撑柱强度的效果。
在再一个实施例中，限位部24包括由轴体21具有第二连接部的端部延伸形成的限位台24-1，配合部包括限位支撑柱和连接于限位支撑柱上的限位 片34，如图9所示。限位片连接在两个限位支撑柱上，作为与限位台配合的抵接平面(第二抵接平面)，增大了限位台截面与配合部的接触面积，防止多次使用过程中，限位台对于限位支撑柱的破坏。应当理解，限位片34可以通过粘贴，或者螺钉紧固的方式设置在限位柱上。可选地，为加强限位片的支撑能力，还可以在限位片上设置紧固螺钉，紧固螺钉将限位片固定在限位支撑柱上。限位片下侧也可以穿过通过轴体的线束，其中线数用于供电、传递信号等。
限位片34设置在两个限位支撑柱31上，增大了限位台24-1截面与配合部的接触面积，防止多次使用过程中，限位台24-1对于限位支撑柱31的破坏。限位片34可以为限位钢片等，其可以通过粘贴，或者螺钉紧固的方式设置在限位支撑柱31上。限位片34下侧也可以穿过线束。
优选的，限位支撑柱31一侧上具有加强支撑能力的加强肋板33，也可以在限位支撑柱31的两侧都设置。螺钉32紧固在限位支撑柱31中，螺钉的螺帽与转轴20上的限位台的截面对齐，当转轴20转动时限位台24-1截面与螺帽接触时，达到限位的效果，并减轻限位台24-1对于限位支撑柱31的损坏。同理，当轴承40转动时，也即右车体10转动时，螺帽与限位台24-1截面接触时达到限位效果。限位支撑柱31、螺钉32为两个，限位台24-1截面也为两个，设置在转轴20右端口两侧，用来限位顺时针和逆时针的转动。
作为优选的，限位部24还包括沿轴体21径向开设的限位槽24-2，内部为中空结构的转轴在沿径向开槽之后必然在槽的两端具有两个截面，即限位槽具有两个截面，且限位槽的两个截面形成第一抵接平面，配合部30还包括卡接在限位槽24-2内的第二限位板35，第二限位板35具有第二抵接平面，参见附图3。第二限位板35位于限位槽中的部分可以是半圆形结构，具有两 个限位端且与限位槽的截面一一对应，两个的限位端形成限位部的第二抵接平面；或者第二限位板位于限位槽中的部分具有一体形成的一个限位端(即一个限位平面)。
具体地，在车体上设有容纳第二限位板的容纳槽，第二限位板35的一端容纳在容纳槽中，另一端容纳在限位槽内，第二限位板35一端形成的第二抵接平面与限位槽形成的第一抵接平面之间具有间隙，当第一车体或第二车体转动至预定角度时，限位台的第一抵接平面与第二限位板的第二抵接平面抵接，从而限制第一车体或第二车体的继续转动。
应当理解，将限位槽与第二限位板配合，第一限位板与限位台配合或限位支撑柱与限位台配合或限位片与限位台配合，双重作用，达到更好的限位效果。
本实施例还提供了一种平衡车，包括上述的平衡车组件。
上述实施方式仅为本实用新型的优选实施方式，不能以此来限定本实用新型保护的范围，本领域的技术人员在本实用新型的基础上所做的任何非实质性的变化及替换均属于本实用新型所要求保护的范围。
