车把105与导向装置共同控制前轮103的行驶方向，在本申请实施例中，车把105是通过两个万向节和两个传动轴与前叉1021相连接，车把105的运动通过第一万向节1061传输到第一传动轴1063上，第一传动轴1063通过第二万向节1062将车把105的运动传输到第二传动轴1064上，第二传动轴1064与前叉1021固定连接，将车把105的运动最终通过前叉1021控制前轮103的转向。
在需要使用折叠代步车时，控制第一车架101和第二车架102绕中心转轴展开，使用者跨坐在车座上，双手握住车把105，双脚放在脚踏板上，就可以开始控制代步车行驶。在使用完毕后，再控制两个车架折叠，即可完成车辆的收纳，使用过程简单，收纳方便。
在本申请实施例中，可折叠代步车主要包括可以绕中心转轴旋转的两个车架，在使用时，车架可以展开，在使用完毕后，即可折叠起来，折叠过程十分简单，车辆在折叠后可以最大程度的减小占用体积。整车结构简单，使用方便，用户在日常使用过程中，方便携带。
进一步的，在本申请实施例中，为了进一步的减少车辆折叠后的体积，所述前叉1021为单臂前叉，所述后叉1011为单臂后叉，所述单臂前叉和单臂后叉分别设置在车轮的两侧，所述单臂前叉设置在车辆前进方向的一侧，所述单臂后叉设置在所述车辆前进方向的另一侧，所述前轮103与所
述后轮104在所述第一车架101、第二车架102折叠后相重叠，局部视图如图12所示。
通过将前叉1021和后叉1011都设置成单臂形式，并且单臂前叉和单臂后叉分别设置在车轮的两侧，并且，将两个车轮交错设置，使得两个车轮在折叠状态时相重叠。前叉1021和后叉1011设置成单臂形式，与传统的双臂形式相比，占用体积更小，结构更简单，车轮的装配流程也更简便，如果车轮出现故障需要拆卸，单臂形式可以更快速地拆卸车轮。
在本申请实施例中，前叉1021和后叉1011呈单臂形式，且前叉1021和后叉1011与车轮的相对位置相反，即如果前叉1021设置在前轮103前进方向的左侧，那么后叉1011就设置在后轮104前进方向的右侧，或者相反，总之保证前叉1021和后叉1011的设置是相对的，使折叠代步车在折叠状态下时，前叉1021和后叉1011不会相互影响。
更进一步的，所述空挡内还设置有避震限位装置110，所述避震限位装置110的一端与所述第二车架102固定连接，所述避震限位装置110的另一端在所述第一车架101和第二车架102展开后与所述第一车架101相接触，局部结构如图10所示。
避震限位装置110设置在第二车架102中，第二车架102上可以设置一个容纳避震限位装置110的空腔，避震限位装置110的一端设置在空腔中，并与第二车架102固定，另一端可沿避震限位装置110的轴线活动，避震限位装置110可以选择弹簧或者其他形式的弹性部件。
更进一步的，所述动力装置包括电池1071、驱动电机1072、传动装置1073，其中：所述电池1071用于为所述驱动电机1072供电，所述驱动电机1072通过所述传动装置1073将动力传输至后轮104。
动力装置可以采用电池1071驱动方式为行驶提供动力，电池1071可以设置在后车架上，采用快速拆卸结构，方便用户取放，驱动电机1072通过传动装置1073与后轮104相连接，将驱动电机1072的动力传递到后轮104上，实现整车的驱动。在车把105上还可以设置控制电机转速的控制装置，方便用户根据路况控制速度，动力装置的具体参数可以采用现有技术中的动力系统。
另外一种情况，所述动力装置还包括轮毂电机，所述轮毂电机设置在所述后轮104内部。轮毂电机通过与轮毂集成一体，可以更方便的将电机的动力传递到驱动轮上。
更进一步的，所述第一车架101和第二车架102为中空结构，所述第一传动轴1063设置在所述第一车架101内部，所述第二传动轴1064设置在所述第二车架102内部，所述第二万向节1062设置在所述空挡中。
在本申请实施例中，为了保证整车的重量较低，可以将第一车架101和第二车架102设置成中空结构，采用强度高的材料制成，在保证整车机械强度的前提下，减少整车质量，方便用户随身携带。在本申请实施例中，车把105通过两个万向节和两个传动轴实现对前轮103的导向。在第一车架101和第二车架102呈中空结构时，将两个传动轴设置在车架内部。
另外，局部视图如图11所示，所述第一车架101上设置有第一磁铁(图中未示出)，所述第二车架102上设置有与所述第一磁铁位置向匹配的第
二磁铁1022，所述第一磁铁和第二磁铁1022在所述第一车架101和第二车架102折叠后吸合。
为了保证可折叠代步车在折叠后的状态更稳定，通过设置在两个车架上设置相对应的磁铁，在车架折叠后通过两个磁铁的吸合作用，可以维持车架的折叠状态，而不会在非人为的作用下展开。用户在需要展开时，只需施加超过两个磁铁吸合力的外力，就可以将车架展开。通过设置磁铁这样的吸合装置，无需设置其他绑带等捆扎结构，整车结构更简单，用户使用也更方便。
同时，为了保证用户骑行时的舒适性，如图1至图12所示，局部视图如图11所示，所述第一车架101或第二车架102上还铰接有脚踏板111。在第一车架101或第二车架102的合适位置铰接脚踏板111，脚踏板111可以仅仅设置一对，如仅设置在第一车架101或仅设置在第二车架102上，当然，也可以在第一车架101和第二车架102上都设置脚踏板111，用户可以根据实际情况选择。脚踏板111可以折叠或展开，在车辆折叠时，脚踏板111也可以折叠起来，减小车辆的占用体积。在骑行使用时，将脚踏板111展开，用户可以将双脚防止在脚踏板111上，提高骑行时的舒适性。
另外，如图13所示，所述车把105包括与所述第一万向节1061固定连接的第一部件1051、设置在所述第一部件两端的第二部件1052和第三部件1053，所述第二部件1052、第三部件1053与所述第一部件1051可折叠连接。
由于为了保证操控的稳定性，车把105整体的宽度一般需要宽于车辆的宽度，这样车辆在折叠后，车把105的宽度就会影响整车的占用体积。
在本申请实施例中，不仅整车可以折叠，车把105也可以折叠。可以将车把105设置成可活动的三部分，在需要折叠时可以折叠，并在展开时，可以固定，方便用户控制方向。
另外，所述动力装置包括脚踏和链条，所述脚踏通过所述链条与后轮104相连接。动力装置不仅可以是电力装置，还可以采用脚踏的形式，满足不同用户的需求。当然，车辆上还可以设置刹车装置，用以行驶时实现制动。或者同时设置车梯，用以放置可折叠代步车时保持稳定。
以上所述仅为本发明的部件实施例而已，并不用于限制本发明，对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
