The invention provides a folding cart which comprises a support assembly comprising a first support and a second support which are arranged at an interval in the first direction; the underframe assembly is arranged between the first bracket and the second bracket and comprises a first underframe hinged to the first bracket and a second underframe hinged to the second bracket; the first bottom frame is constructed to comprise a first parallel rod structure which is vertically arranged, and the second bottom frame is constructed to comprise a second parallel rod structure which is vertically arranged. The first parallel rod structure and the second parallel rod structure are hinged to the groove connecting piece and are configured to respond to movement of the groove connecting piece in the vertical direction to drive the first bottom frame and the second bottom frame to move synchronously. The chassis assembly with the parallel rod structure is adopted, the supporting strength is improved, meanwhile, overall folding or unfolding of the chassis assembly is achieved through the groove connecting pieces, and folding or unfolding operation is simplified. The folding cart is not provided with a side support, the packaging size is greatly reduced after the folding cart is folded, and the folding cart is convenient to transport, use, store and store.
本公开提供一种折叠推车,包括:支架组件,包括沿第一方向间隔布置的第一支架和第二支架;底架组件,布置于第一支架和第二支架之间并包括铰接于第一支架的第一底架和铰接于第二支架的第二底架;第一底架构造为包括竖向布置的第一平行杆结构,第二底架构造为包括竖向布置的第二平行杆结构,第一平行杆结构和第二平行杆结构铰接于槽连接件并配置为响应于槽连接件沿竖向方向的运动而分别带动第一底架和第二底架同步运动。本公开采用具有平行杆结构的底架组件,提高了支撑强度,同时通过槽连接件实现底架组件整体折叠或展开,简化了折叠或展开操作。本公开的折叠推车没有侧边支架,折叠后包装体积大幅减小,便于运输、使用和收纳储存。
