Child stroller and stand platform assembly thereof

A child stroller and a stand platform assembly thereof are disclosed. The stroller includes a frame 12, a brake assembly 14 connected to the frame, two rear wheels 16 connected to the brake assembly, and the stand platform assembly 18 for carrying a child in a standing position. The stand platform assembly includes a platform (182, figure 6) connected to a rear cross bar of the frame, and two sidewalls (184) connected to two opposite sides of the platform. When the stroller is folded, said stroller is capable of being supported upright by the sidewalls and the rear wheels (figure 7), which solves the inconvenience in placing a folded conventional stroller. The platform is capable of being pivoted upwards when one of the sidewalls hits an object, thus preventing it from being damaged.
