The invention relates to a front wheel mechanism of a three-wheeled child cart. The front wheel mechanism comprises a sliding guiding module and a double-connecting rod mechanism, which are mounted on a frame, wherein a front fork module is connected with the sliding guiding module; the front fork module and the front wheel module can slide in a left-right direction of the child cart under the guiding of the sliding guiding module; the double-connecting rod mechanism comprises a first connecting rod and a second connecting rod which are rotationally connected with each other; the end part of the first connecting rod is connected with a rotating shaft; the the first connecting rod can rotate with the rotating shaft; and the end part of the second connecting rod is rotationally connected with the frame through a pivot. According to the front wheel mechanism of the three-wheeled child cart provided by the invention, as the front wheel mechanism is arranged as a structure capable of moving in the left-right direction of the three-wheeled child cart, the supporting point of the front wheel module can move so that a supporting system of the child cart formed by the front wheel module and a rear wheel module is high in stability and can adapt to different road situations; the climbing performance is stable in places with slopes; and the three-wheeled child cart cannot turn over.
