The frame comprises side frame bodies which are oppositely arranged, a first folding assembly is connected between the side frame bodies, each side frame body comprises a side vertical pipe, a side bottom frame piece is arranged on the lower side of each side vertical pipe, each side vertical pipe is slidably connected with a side sliding piece, a middle vertical pipe is arranged between every two adjacent side vertical pipes, and the middle vertical pipes are connected with side sliding pieces in a sliding mode. A center connecting piece is further arranged between the oppositely-arranged side frame bodies, the center connecting piece and the oppositely-arranged middle vertical pipes are connected with bottom frame transverse pipes, one end of each bottom frame transverse pipe is rotationally connected with the center connecting piece, and the other end of each bottom frame transverse pipe is movably connected with the corresponding middle vertical pipe. The side frames based on the frame can be folded in the left-right direction (x direction) and the front-back direction (y direction), after the center connecting piece and the bottom frame transverse pipe are additionally arranged, on one hand, the upper limit of the overall loading weight of the frame is increased, and on the other hand, the front frame body and the rear frame body are connected through the bottom frame transverse pipe and the transverse pipe sliding piece, so that the loading capacity is improved. Good structural conditions are provided for the frame to be folded in the z direction and not to be lengthened.

    本申请公开了一种车架和推车,包括相对设置的侧框架体,侧框架体之间连接第一收拢组件,侧框架体包括侧边竖管,侧边竖管下侧设置有侧边底框件,侧边竖管滑动连接有侧边滑动件,相邻侧边竖管之间设置中间竖管,相对设置的侧框架体之间还设置有中心连接件,中心连接件与相对设置的中间竖管均连接有底框横管,底框横管一端与中心连接件转动连接,另一端与中间竖管活动连接。基于车架的侧边框架能够在左右方向(x方向)和前后方向(y方向)收拢,在增加中心连接件和底框横管之后,一方面,提升了车架整体的载物重量上限,另一方面,通过底框横管、横管滑动件连接前侧框架体和后侧框架体,给车架收拢z方向不会变长提供了良好的结构条件。
