A shock-proof baby stroller comprises a push rod frame, a front support, a main joint and a multi-connecting-rod virtual turning point shock-proof assembly. The multi-connecting-rod virtual turning point shock absorption assembly comprises a shock absorber, a lever, a swing rod, a rear support and a connecting frame. The first end of the lever is rotationally connected to the first hinge point of the rear bracket, the middle is rotationally connected to the connecting frame, and the second end is rotationally connected to the movable end of the shock absorber; the first end of the swing rod is rotationally connected to the second hinge point of the rear support, and the second end of the swing rod is rotationally connected to the connecting frame. The first hinge point and the second hinge point are staggered in the height direction and the front-back direction; the shock absorber is positioned in the connecting frame; the intersection point of the connecting line of the first hinge point and the first rotating point and the connecting line of the second hinge point and the second rotating point is a virtual rotating point, and the virtual rotating point keeps the trend of moving towards the telescopic direction of the shock absorber when the frame vibrates. According to the invention, impact energy generated by road bumping can be absorbed, children, especially newborns and infants, are effectively protected, and the safety is comprehensively improved.
