Abstract
The utility model discloses a foldaway child trolley. The frame of the trolley comprises a front wheel bracket, a rear wheel bracket, a push rod, side seat rods and a front seat rod; the front seat rod is positioned between the front parts of the side seat rods which are arranged at both sides of the frame, when the frame is converted from the unfolding state to the folding state, the side seat rods of both sides are arranged in a sliding way with the front seat rod, a changeover mechanism which is used for enabling the side seat rods to be arranged with the front seat rod in a fixed way or in a sliding way is arranged between at least one side seat rod and the front seat rod; when the frame is folded, due to the rotation movement made by the side seat rods relative to the front wheel bracket as well as the sliding movement relative to the front seat rods or a connecting piece, the included angle formed by the front wheel bracket and the rear wheel bracket after the trolley is folded can be very small; thus the volume of the folded trolley is relatively smaller, and the trolley is convenient for storage and carrying.
