具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解。
参考附图1至附图8，本实施例中的折叠儿童车，它包括后车架1、前车架2、前侧杆3、后侧杆4。
后车架1的底部连接有车轮，具体地，车轮包括连接在后车架1底部后侧的后轮80、连接在后车架1左右两侧且位于后轮80前方的前侧轮81。本实施例中的折叠儿童车由电机驱动，后轮80为驱动轮。后车架1上连接有座位7，具体地，座位7位于后轮80的上方。
前车架2与后车架1可前后移动地相连接。具体地，前车架2和后车架1均沿着前后方向延伸，且前车架2为U形，其开口朝后。前车架2自前而后地从后车架1的前端***其中。
前侧杆3的前部与前车架2相转动连接。具体地，前车架2与前侧杆3之间通过第一转 轴31转动连接，在后车架1上开设有导向槽11，该第一转轴31可前后滑动地设置在该导向槽11内。
后侧杆4的外端部与前侧杆3的后部相转动连接，且后侧杆4的内端部与后车架1相转动连接。需要说明的是，本实施例中的内外方向是指：靠近折叠儿童车的对称面的方向为内，远离折叠儿童车的对称面的方向为外。后侧杆4的外端部或前侧杆3的后部连接有后侧轮82，本实施例中，后侧轮82连接在后侧杆4的外端部。
在一种更为优选的实施方案中，折叠儿童车还包括脚踏杆5、连杆6。
脚踏杆5与前车架2相转动连接。具体地，脚踏杆5位于前车架2的前部。
连杆6与后车架1可前后移动地相连接，具体地，连杆6位于折叠儿童车的对称面上。后车架1具有同样位于折叠儿童车的对称面上的插管12，连杆6自前而后地从插管12的前端***其中。插管12的延伸方向与导向槽11的延伸方向一致。
在一种更为优选的实施方案中，插管12上开设有第一滑槽13，连杆6上设有销子63，该销子63可前后滑动地位于第一滑槽13内，通过销子63与第一滑槽13的配合，既能够起到插管12与连杆6之间的滑动导向作用，又能够起到限位的作用，当折叠儿童车在打开状态时，销子63位于第一滑槽13的前端，当折叠儿童车在折叠状态时，销子63位于第一滑槽13的后端。连杆6的前部与脚踏杆5可滑动且可转动地相连接。连杆6与脚踏杆5的连接处位于前车架2与脚踏杆5的连接处的后方。具体地，脚踏杆5的内端部上连接有第二转轴51，该第二转轴51可滑动地设置在连杆6的前部。更为具体地，连杆6的前部开设有滑槽61，第二转轴51可滑动地设置在该滑槽61内。本实施例中的第二转轴51沿左右方向滑动，连杆6的前部具在左右方向延伸的接头62，滑槽61开设在该接头62上。
上述的前侧杆3、后侧杆4、脚踏杆5均有两个，且对称地设置在前车架2和后车架1的左右两侧。
在一种更为优选的实施方案中，脚踏杆5在其与前车架2的连接处和第二转轴51之间的部分呈弧形弯折，以使折叠儿童车在折叠后，左右两个脚踏杆5与接头61共同呈U形，从而使脚踏杆5在折叠后更加贴合前车架1。
本结构的折叠儿童车在折叠后，左右两个前侧杆3分别位于车体左右两侧的最外侧，所以在一种更为优选的实施方案中，前侧杆3的前部和后部均向内侧弯折，以使折叠儿童车在折叠后，车体的两侧没有过于凸出的棱角，防止刮碰。
本折叠儿童车还包括锁定装置，用于将整车锁定在打开状态。
在一种更为优选的实施方案中，前车架2和后车架1之间具有多个滑动档位，且前车架2与后车架1之间设置有将二者锁定在相应滑动档位的限位机构。限位机构可以采用销孔配 合等现有技术结构。通过设置前车架2与后车架1之间的多个滑动档位，以此来调节脚踏杆5和座位7之间的距离，从而适应不同身高的儿童乘坐。
工作原理：
折叠儿童车在打开状态下，如附图1和附图2所示，脚踏杆5在左右方向延伸，左右两侧的前侧杆3和后侧杆4分别在后车架2的左右两侧呈翅膀状。当需要折叠时，如附图3和附图4所示，将前车架1向后推，使前车架1逐渐***后车架2，从而带动前侧杆3和后侧杆4向后转动而向后车架2靠拢，前车架1向后移动的同时，通过脚踏杆5带动连杆6向后移动而***插管12中；进一步向后推动前车架1，如附图5和附图6所示，连杆6前部的接头62抵在插管12的前端，连杆6不再向后移动，前车架1继续向后移动则带动脚踏杆5向后转动，左右两侧的脚踏杆5分别向前车架1的左右两侧靠拢。直至整车完全折叠，如附图7和附图8所示。
本折叠儿童车，通过连杆机构实现了坐式儿童滑行车的折叠，整车结构简单新颖，折叠操作方便，折叠后体积小。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
