童车
技术领域
本发明涉及一种童车。
背景技术
现有技术中，童车一般包括可折叠的推车车架、设置于推车车架底部的轮组件，推车车架展开时通过一锁定装置来锁定。能使推车车架折叠的结构有很多种，而在童车行业的发展中，如何使推车车架更易折叠、使其折叠后的体积变小等一直是追求和探讨的目标。
发明内容
本发明要解决的技术问题是提供一种可快速且方便地折叠的童车。
在解决上述技术问题，本发明采用的一种技术方案是：一种童车，包括可折叠的车架、用于将车架锁定的锁定装置、设置于车架底部的轮组件、设置在车架上的座位，车架包括前轮支架、上部与前轮支架后部通过第一转轴相转动连接的右侧后轮支架、上部与前轮支架后部通过第二转轴相转动连接的左侧后轮支架、右侧推杆、左侧推杆、上部与右侧推杆通过第七转轴相转动地连接下部与前轮支架后部通过第三转轴相转动地连接的右侧后撑杆、上部与左侧推杆通过第八转轴相转动地连接下部与前轮支架后部通过第四转轴相转动地连接的左侧后撑杆，前轮支架具有沿着前后方向延伸的前轮杆，前轮杆上设置有可沿其滑动的滑动件，滑动件通过第五转轴转动连接一第一驱动杆，该第一驱动杆的上部与右侧推杆的下部通过第九转轴相转动地连接，第一驱动杆的下部与左侧后轮支架通过第十二转轴相转动地连接；滑动件还通过第六转轴转动连接一第二驱动杆，该第二驱动杆的上部与左侧推杆的下部通过第十转轴相转动地连接，第二驱动杆的下部与右侧后轮支架通过第十一转轴相转动地连接。
在某些进一步的实施方式中，第二转轴、第三转轴、第五转轴、第七转轴、第九转轴及第十二转轴的轴心线都相平行并且将与这些轴心线相垂直的平面定义为第一平面，第一转轴、第四转轴、第六转轴、第八转轴、第十转轴及第十一转轴的轴心线都相平行并且将与这些轴心线相垂直的平面定义为第二平面，第一平面与第二平面相交叉。由于第一平面与第二平面相交叉，使得左侧推杆与右侧推杆在向前移动的同时也相互向对方靠拢，左侧后轮支架与右侧后轮支架向前翻转的同时也相互向对方靠拢，从而使得车架不仅可以是上下方向、前后方向减小体积，还可以在左右方向减小体积。
在某些更进一步实施方式中，推车车架还包括在横向支撑左侧推杆和右侧推杆的可折叠的推杆横撑。
在某些再进一步实施方式中，车架还包括下端部与右侧推杆的上端部相转动地连接的右侧推把杆、下端部与左侧推杆的上端部相转动地连接的左侧推把杆，推杆横撑的两端部分别与右侧推把杆和左侧推把杆相转动地连接。
在某些实施方式中，第三转轴位于第一转轴的上方，第四转轴位于第二转轴的上方。
在某些实施方式中，前轮杆包括位于前轮支架的左侧部的左前轮杆、位于前轮支架的右侧部的右前轮杆。滑动件的左右两侧部分别开有左穿孔与右穿孔，左前轮杆插在左穿孔内，右前轮杆插在右穿孔内。
在某些进一步实施方式中，左前轮杆与右前轮杆相固定地设置构成一个整体。
在某些进一步实施方式中，第一驱动杆与第二驱动杆位于左前轮杆与右前轮杆之间。
在某些进一步实施方式中，前轮支架包括还具有位于其后部的连接座，连接座与前轮杆相固定地连接。
在某些实施方式中，第一驱动杆与滑动件的右侧部通过第五转轴相转动地连接，第二驱动杆与滑动件的左侧部通过第六转轴相转动地连接。
本发明的范围，并不限于上述技术特征的特定组合而成的技术方案，同时也应涵盖由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本申请中公开的（但不限于）具有类似功能的技术特征进行互相替换而形成的技术方案等。
由于上述技术方案运用，本发明与现有技术相比具有下列优点：折叠时，向下按右侧推杆以及左侧推杆，使得右侧后撑杆以及左侧后撑杆向前翻转，同时右侧推杆及左侧推杆分别带动第一驱动杆、第二驱动杆向下并朝前倾斜地移动，从而带动滑动件沿前轮杆向下滑动，左侧后轮支架、右侧后轮支架向前翻转，直至实现折叠。
