The invention discloses a folding device of a cart and the cart, the cart comprises a push handle group, a front foot group and a rear foot group, the folding device comprises a first connecting piece, a second connecting piece and a third connecting piece, the first connecting piece is used for being relatively fixedly connected with the push handle group and rotatably connected with the front foot group; the second connecting piece is rotationally connected with the first connecting piece and is used for relatively and fixedly connecting the rear leg group; the third connecting piece is rotationally connected with the second connecting piece and is used for being connected with the front foot set in a sliding mode, and the first connecting piece, the second connecting piece and the third connecting piece form a connecting rod sliding block mechanism. According to the folding device and the cart in the embodiment of the invention, the linkage relation is simple by constructing the connecting rod sliding block mechanism, and the cart is not prone to clamping stagnation in the unfolding and folding process; the connecting rods and the supporting rods among the front foot set, the rear foot set and the push handle set are simplified into the connecting pieces, so that the stroller is simpler in overall structure, low in production cost, small in size after being folded and light in weight.

    本发明公开了一种推车的折叠装置和推车,推车包括推把组、前脚组以及后脚组,折叠装置包括第一连接件、第二连接件以及第三连接件,第一连接件用于相对固定地连接推把组并转动连接前脚组;第二连接件转动连接第一连接件,并用于相对固定地连接后脚组;第三连接件转动连接第二连接件,并用于滑动连接前脚组,其中,第一连接件、第二连接件和第三连接件构造出连杆滑块机构。根据本发明实施例中的折叠装置和推车,通过构造连杆滑块机构,使连动关系简单,推车在展开和折叠过程中不易发生卡滞;通过将前脚组、后脚组以及推把组之间的连接杆和支撑杆简化为连接件,使推车的整体结构更简单,生产成本低,折叠后体积小、重量轻。
