[0029] The front wheels 2 are a pair of universal wheels, and the two rear wheels 3 are driving wheels. A driving mechanism, a brake mechanism and a battery pack are arranged between the two rear wheels 3. The driving mechanism can drive the rear wheels 3 to rotate, and the battery pack can supply power to the driving motor and the electric telescopic cylinder 10. The two ends of the rotating joint 8 are respectively connected to the upper end of the front rocker 4 through the lower end of the push rod 6; the connecting frame 9 is fixedly connected to the lower part of the two front rockers 4, and the connecting frame 9 has the function of a crank; the baby carrier 11 can be a baby basket or a baby seat.

[0030] When the electric telescopic cylinder 10 is extended, the front rocker 4 and the push rod 6 are pushed to rotate to the unfolded state through the connecting frame 9, so that the upper end of the front rocker 4 and the lower end of the push rod 6 are aligned, so that the front rocker 4 and the push rod 6 are in line, and form a triangular frame with the base frame 1 and the rear rocker 5. The two push rods 6 support the baby carrier 11 at a suitable height, and the user can push and control the direction of the baby carriage through the handle 7.
