The invention relates to a trolley chassis, a trolley frame and a flat folding trolley. The technical problem that an existing flat folding trolley is not high in structural strength is solved. Comprising a horizontally-arranged frame-shaped bottom frame body, the bottom frame body is provided with two movably-connected bottom frame half bodies, and the ends, away from each other, of the two bottom frame half bodies are rotating ends; the ends, close to each other, of the two bottom frame half bodies are connected through a flat folding movable connecting structure which can enable the two bottom frame half bodies to be folded upwards in the vertical direction located at the connecting position of the two bottom frame half bodies under the action of external force, and the width of the bottom frame bodies is not changed in the folding process. The lower end of the bottom frame body is provided with a plane rotation cross supporting structure used for bearing the bottom frame body. The frame has the advantages that the front support and the rear support are connected through the bottom frame, the overall bearing capacity of the frame can be improved, and the bearing capacity of the frame can be further improved through the plane rotation cross supporting structure arranged at the lower end of the bottom frame.

    本发明涉及一种手推车底架、车架及平折手推车。它解决了现有平折手推车结构强度不高等技术问题。包括水平设置且呈框状的底架体,底架体具有两个活动相连的底架半体,两个底架半体相互远离的一端为转动端,两个底架半体相互靠近的一端之间通过当在外力作用下能使两个底架半体朝向位于两个底架半体连接处的竖直方向向上折叠且折叠过程中底架体宽度不变的平折活动连接结构相连,底架体下端设有用于承托底架体的平面旋转交叉支撑结构。优点在于:前支架与后支架之间通过底架相连能够提高车架整体的承载能力,且通过设置在底架下端的平面旋转交叉支撑结构能够进一步提高车架的承载能力。
