Hand-pulled drive type child cart structure

Abstract

This utility model discloses a hand-pulled drive children's stroller structure, relating to the field of children's stroller technology. It includes a seat, a drive mechanism, a front moving beam, and a rear moving beam. The drive mechanism is hinged to the front center of the seat base. The front moving beam is horizontally positioned at the front of the drive mechanism, and the rear moving beam is horizontally fixed through the rear of the seat. In use, the child sits on the cushioned backrest, holds the control lever, and uses their feet to push off the ground. In normal mode, the stroller can be driven directly by pushing off the ground with their feet. To enhance the fun of driving, the child can use their hips and arms to apply pressure to the seat, alternating between a downward pressure state and a rebound state to propel the stroller forward. Simultaneously, the child can control the turning direction by pushing the front moving beam with their left and right feet. This drive method effectively improves the child's coordination and prevents numbness in the hips due to prolonged sitting.
