具体实施方式
以下将结合附图，对本实用新型进行更为详细的描述，需要说明的是，下参照附图对本实用新型进行的描述仅是示意性的，而非限制性的。各个不 同实施例之间可以进行相互组合，以构成未在以下描述中示出的其他实施例。

请一并参阅图2至图8，该壳体100包括：第一壳体10及第二壳体20，第一壳体10与第二壳体20相连接并形成用于放置电子元器件等部件的安装腔30。
如图3及图6所示，在第一壳体10的侧面边缘设有第一突起部11，在第二壳体20的侧面边缘形成有与第一突起部11对应设置的第一凹槽21，第一突起部11能够嵌入至第一凹槽21内，且第一突起部11的形状与第一凹槽21相适配，当第二壳体20与第一壳体10相连接时，第一突起部11嵌在第一凹槽21内并与第一凹槽21相紧贴，能够避免第一壳体10与第二壳体20的侧面连接处出现间隙，进而提高了第一壳体10与第二壳体20间的侧面密封性，防止水等液体由侧面渗入至安装腔30内。
可以理解的，为了提高第一壳体10及第二壳体20同一侧的轴向端面连接处的密封性，也可以在第一壳体10及第二壳体20同一侧的轴向端面位置处对应设置第一突起部11及第一凹槽21，即：第一壳体10面向第二壳体20的边缘位置处均设置有第一突起部11，相应的，第二壳体20面向第一壳体10的边缘位置处均对应设置有第一凹槽21，从而基于第一突起部11与第一凹槽21的嵌接配合来提高壳体100的整体密封性。
在其中一实施例中，为了提高第一壳体10与第二壳体20的轴向端面连 接位置的密封性，如图4及图7所示，在第一壳体10的一轴向端面形成有第一台阶12，即第一台阶12位于第一壳体10远离转轴的端面上；在第二壳体20的一轴向端面形成有第二台阶22，第二台阶22与第一台阶12相对应设置，即第二台阶22位于第二壳体20远离转轴的端面上，当第一壳体10与第二壳体20相连接时，第一台阶12与第二台阶22之间相交错抵紧，以有效防止水等液体经由第一壳体10与第二壳体20的端面连接处渗入至安装腔30内的效果。
可以理解的，为了提高第一壳体10与第二壳体20的侧面连接位置处的密封性，也可以在第一壳体10与第二壳体20相对的侧面边缘位置处分别对应设置第一台阶12及第二台阶22，即：第一壳体10面向第二壳体20的边缘位置处均设置有第一台阶12，相应的，第二壳体20面向第一壳体10的边缘位置处均对应设置有第二台阶22，从而基于第一台阶12与第二台阶22的交错抵紧配合来提高壳体100的整体密封效果。
在其中一实施例中，如图6所示，第一凹槽21包括有第一侧壁211及第二侧壁212，第一侧壁211与第二侧壁212之间相平行间隔，第一侧壁211靠近安装腔30，第二侧壁212远离安装腔30，同时，第一侧壁211的厚度小于第二侧壁212的厚度，如此设置能够有效避免受到外力碰撞而损坏第一凹槽21，有效提高了第一凹槽21的稳固性，确保第一壳体10、第二壳体20之间始终处于密封状态，可有效延长平衡车的使用寿命。
在其中一实施例中，如图7所示，第二台阶22形成有台阶面一221与台阶面二222，台阶面一221靠近安装腔30，台阶面二222远离安装腔30，并且台阶面一221与台阶面二222之间形成高度差；如图4所示，第一台阶12形成有台阶面三121与台阶面四122，台阶面三121靠近安装腔30，台阶面 四122远离安装腔30，台阶面三121与台阶面四122之间也形成有高度差，当第一壳体10与第二壳体20连接为一体时，台阶面三121与台阶面一221相抵紧，同时台阶面四122与台阶面二222相抵紧，即：第一台阶12与第二台阶22之间相互交错抵紧。另外，台阶面一221的高度高于台阶面二222，相应的，台阶面三121低于台阶面四122。如此设置，在下雨天，雨水可由第一壳体10朝向第二壳体20所处方向流动，此时雨水仅能在第二台阶22面处流动，不会流动至安装腔30内，具有较好的防水效果。
可以理解的，第一壳体10、第二壳体20的侧面厚度大于其端面厚度，从而在第一壳体10、第二壳体20的侧面适于设置第一突起部11与第一凹槽21配合安装；第一壳体10、第二壳体20的端部适于设置第一台阶12和第二台阶22配合安装。
在其中一实施例中，请一并参阅图8及图9，为了丰富平衡车的功能，在壳体100上还设有安装座40，该安装座40上可设置灯、音箱等设备。在壳体100的侧面开设有第一安装孔50，安装座40的形状与第一安装孔50相适配，安装座40可嵌设在第一安装孔50内。
为了提高安装座40与第一安装孔50之间的密封性，在安装座40的侧面形成有第三台阶41，第三台阶41的台阶面与第一壳体10的内侧面及第二壳体20的内侧面相抵紧，即：当安装座40嵌设在第一安装孔50内时，第三台阶41位于安装腔30内部，并且第三台阶41的台阶面与第一壳体10的内侧面及第二壳体20的内侧相紧密贴合，从而达到防止液体渗入的效果，具有较好的密封性。
在其中一实施例中，第一安装孔50包括第一缺口51及第二缺口52，第一缺口51形成在第一壳体10的侧面边缘，第二缺口52形成在第二壳体20 的侧面边缘，第一缺口51与第二缺口52相对应设置。可以理解的是，第一安装孔50是由位于第一壳体10的第一缺口51与位于第二壳体20的第二缺口52相围设形成的。
为了提高安装座40的安装稳固性，在安装腔30内还设置有支撑柱60，当安装座40设在第一安装孔50处时，该支撑柱60与安装座40相抵，以防止安装座40松动。
在其中一实施例中，请一并参阅图10至图14，为了提高平衡车中两个壳体100连接位置处的防水性能，该平衡车还包括有连接密封结构200，连接密封结构200轴向开设有第一贯穿孔210，两个壳体100相对的端部均穿入至该第一贯穿孔210内，以使转轴位于两个壳体100之外的部分处于第一贯穿孔210内，以基于连接密封结构200的防水性能来保护转轴。
其中，该连接密封结构200包括：第一密封件220及第二密封件230，第一密封件220与第二密封件230相连接并围成了第一贯穿孔210。第二密封件230上形成有第二凹槽240，第二凹槽240位于第二密封件230与第一密封件220相连接的位置处，第一密封件220面向第二密封件230的一侧设有第二突起部250，第二突起部250与第二凹槽240相对应设置，第二突起部250能够嵌入第二凹槽240内。当第一密封件220与第二密封件230相连接时，第二突起部250嵌设在第二凹槽240内，此时，第二突起部250与第二凹槽240相紧贴配合，可有效提高连接密封结构200的防水效果。
上述实施例中所提供的壳体100及平衡车的组装过程可描述为：
用户将第一壳体10的第一突起部11嵌设在第二壳体20的第一凹槽21内，第一台阶12与第二台阶22相交错抵紧，此时，第一突起部11与第二壳体20相紧贴配合，第一台阶12与第二台阶22之间相紧贴；之后，用户将第 一密封件220的第二突起部250嵌设在第二密封件230的第二凹槽240内，此时，第二突起部250与第二凹槽240相紧贴，平衡车的两个壳体100相对的端部均位于第一贯穿孔210内。
上述实施例中所提供的壳体100及具有该壳体的平衡车是通过在第一壳体10、第二壳体20的侧面边缘分别设有第一突起部11及第一凹槽21，以基于第一突起部11及第一凹槽21的嵌接配合，达到防止液体经第一壳体10、第二壳体20的侧面连接处渗入至壳体100内部的效果；同时，在第一壳体10、第二壳体20的同一端面处分别设有第一台阶12及第二台阶22，以基于第一台阶12及第二台阶22的交错抵紧，达到防止液体经第一壳体10、第二壳体20的轴向端面连接处渗入至壳体100内部的效果，具有较好的防水性能。
