The invention relates to a folding cart which comprises a first leg assembly, a second leg assembly, a joint assembly, a first rotating block, a second rotating block and a locking piece, wherein the first rotating block and the second rotating block are connected in a pivoted mode, and the locking piece is movably arranged between the first rotating block and the second rotating block. The locking piece is used for limiting or unlocking relative rotation of the first rotating block and the second rotating block; the seat assembly comprises an unlocking structure, a backrest and a seat plate, the backrest/seat plate is connected to the joint assembly in a pivoted mode, the unlocking structure is arranged between the backrest and the joint assembly, and when the backrest is folded towards the seat plate, the unlocking structure is arranged between the backrest and the joint assembly. And the unlocking structure drives the locking piece to slide so as to unlock the first rotating block and the second rotating block, so that the first rotating block and the second rotating block can rotate relatively. The unlocking structure is arranged between the backrest and the joint assembly, in the folding operation, folding of the seat plate and unlocking of the two leg assemblies are completed at the same time, the folding steps are reduced, and the user experience is improved. And the structure of the folding cart is simplified.

    本发明涉及了一种折叠推车,包括第一腿组件,第二腿组件,关节组件,包括枢转连接的第一转动块和第二转动块,以及可移动地设置在第一转动块与第二转动块之间的锁定件,锁定件用于限制或解锁第一转动块与所述第二转动块的相对转动;以及座椅组件,包括解锁结构、靠背与座板,靠背/所述座板枢转连接于所述关节组件,解锁结构设置于所述靠背与所述关节组件之间,所述靠背在往所述座板折叠时,所述解锁结构驱动所述锁定件滑移以解锁所述第一转动块与所述第二转动块,使二者能够相对转动。将解锁结构设置在靠背与关节组件之间,在折叠操作中,同时完成了座板的折叠与两个腿组件的解锁,减少了折叠步骤,提升用户体验。且简化了折叠推车的结构。
