具体实施方式
实施例一
如图1所示，本实施例的推车包括：推杆11、前支架12、后支架13及侧连杆14，推杆11、前支架12、后支架13及侧连杆14均左右对称设置。其中，前支架12的上端及侧连杆14的上端均与推杆11的下端销接，前支架12的下端和侧连杆14的下端均与后支架13销接，两个后支架13之间转动连接有第一连接组件，该推车还包括：左右对称设置的滑动连杆15及滑套16，滑套16设置在后支架13上且能够沿后支架13滑动，滑动连杆15的第一端与侧连杆14销接，滑动连杆15的第二端与滑套16销接。
在一实施例中，后支架13上设有与前支架12的下端销接的前轮座17；推杆11的下端设有推杆关节19，推杆关节19的第一端与推杆11的下端销接，推杆关节19的第二端与前支架12的上端连接。
本实施例在两个推杆11的上端均设有扶手18，且在推车为折叠状态时，两个扶手18分别与两个前轮座17相邻。设置扶手18方便推行该推车，且增设扶手 18并没有影响推车折叠后的尺寸。
为了进一步方便推行该推车，还可在两个推杆11的上端之间转动连接一握把21，且握把21中部上设有能够使该握把21向中间折合的轴部22。如此，对握把21中间施加向下的作用力，握把21即可向中间折合。
本实施例中的第一连接组件包括两个交叉枢接的底撑杆31，两个底撑杆31的四个端部分别与两个前轮座17及两个滑套16一一对应，且转动连接。如此，当多个销接处转动时，通过滑动连杆15与滑套16带动两个底撑杆31交叉转动，两个底撑杆31的交叉转动实现推车的收合或展开。
本实施例的推车还包括第二连接组件，第二连接组件设置为增强该推车的结实度，第二连接组件包括两个交叉枢接的前撑杆41，两个前撑杆41的端部中的其中两个端部分别与两个前轮座17一一对应且转动连接，另外两个端部分别与两个侧连杆14一一对应且转动连接；且前撑杆41与侧连杆14转动连接的一端转动连接有座杆42，座杆42起支撑作用，为使座杆42能够稳定的支撑。本实施例在两个前支架12上均转动连接有与座杆42滑动套接的导套43，推车在收合过程中，座杆42可相对导套43移动，如此，当推车收合后，座杆42与前支架12平行，确保了推车收合后的形态较顺畅平整。
为了确保该推车收合后形态更加顺畅平整，本实施例将侧连杆14与后支架13的销接处设置于前轮座17与滑套13之间。
本实施例中的推车的车轮安装在上述后支架13的两端，车轮包括前轮51和后轮52，所述前轮51连接于所述后支架13的第一端，所述后轮52连接于所述后支架13的第二端。
本实施例中的推车折合过程如图2和图3所示，先使推杆11绕推杆关节19转动，因侧连杆14与推杆11销接，推杆11转动过程中使侧连杆14受力，侧连杆14使滑动连杆15通过滑套16在后支架13上滑动，滑套16带动两个底撑杆31交叉转动，使底撑杆31两端的支架向中间靠拢，从而使两个前撑杆41交叉转动，握把21向中间折合，多个杆件继续向中间靠拢，最后将推杆11翻折在前支架12上，即可折成图3所示的状态。可见，本实施例中的推车的折合方式能够有效缩小推车的宽度、长度与体积，且收合后的形态较顺畅平整，占用空间小。
