Abstract

A baby stroller, its stroller frame includes a first front wheel bracket, a second front wheel bracket, and a first front wheel bracket whose lower end is rotatably connected to the upper end of the first front wheel bracket and the upper end of the second front wheel bracket. One push bar and the second push bar, the first rear wheel bracket, the second rear wheel bracket, the cross brace, the cross brace, the lower end of the first front wheel bracket and the lower end of the second front wheel bracket are rotated The upper end of the first rear wheel bracket is rotatably connected to the first front wheel bracket, and the upper end of the second rear wheel bracket is rotatably connected to the second front wheel bracket. Since the upper end of the first rear wheel bracket is directly connected in rotation with the first front wheel bracket, and the upper end of the second rear wheel bracket is directly connected in rotation with the second front wheel bracket, the connection between the first bottom link and the second front wheel bracket is omitted. The second bottom link, thus reducing the number of rods for the stroller frame, reduces production costs.
