As with the cart, an assist mechanism is provided to assist in folding or unfolding the cart frame. [Solution] The frame of the cart includes a first rod and a second rod that rotate relative to each other, the frame is in an unfolded state when the first rod and the second rod rotate relative to a first position, and the frame is in a folded state when the first rod and the second rod rotate relative to a second position, and the assist mechanism includes an elastic member that drives the first rod and the second rod to rotate relative to each other toward the first position or the second position. The assist mechanism according to the present disclosure not only facilitates the user to unfold or fold the frame more easily, but also allows the frame to be unfolded or folded in a predetermined position, thus avoiding potential safety hazards.
