Embodiment
[0020] Example: such as Figure 1 to Figure 8 As shown, a rear wheel rotation structure of a baby stroller includes two rear brackets 1, two rear wheel assemblies 2, and a rear support assembly 3 arranged between the two rear brackets 1 and capable of being folded left and right. The lower end of 1 is inserted into the rear wheel seat 4 of the rear wheel assembly 2 and is pinned and fixed by the front and rear rotation shaft 5. The inner side wall of the rear wheel seat 4 is provided with a U-shaped hole for the rear bracket 1 to pass through. Slot 6, the inner side of the rear wheel base 4 is closely equipped with a rotating pin 7, a first linkage rod 8 is connected between the rotating pin 7 and the back support assembly 3, when the back support assembly 3 is folded left and right, the rear support assembly 3 The support assembly 3 drives the first linkage rod 8 to move up, and the first linkage rod 8 drives the rear wheel assembly 2 to rotate around the rotation axis 5 by r...

The invention discloses a rear wheel rotating structure of a baby trolley, which comprises two rear support frames, two rear wheel components and rear supporting components, wherein the rear supporting components are arranged between the two rear support frames and can be transversely folded. The lower ends of the rear support frames are inserted into rear wheel seats of the rear wheel components and are pin-jointed and fixed through transverse rotating shafts; U-shaped grooves for the rear support frames to pass through are formed on the inner side walls of the rear wheel seats; a rotary pin is tightly matched at the inner side part of each rear wheel seat; and a linkage rod is connected between the rotary pin and the corresponding rear supporting component. The rear wheel rotating structure of the baby trolley has the advantages that when being transversely folded, the rear supporting components drive the linkage rods to move upwards; the linkage rods drive the rear wheel components to rotate around the rotating shafts through the rotary pins; the rear support frames rotate in the U-shaped grooves; when a whole vehicle is folded, the rear wheel components are erected on the ground; and rear wheels of the rear wheel components are flatly placed on the ground. Therefore, the folded whole vehicle is smaller in volume, is convenient to package and is also convenient for the erection of a folded vehicle frame.
Description
technical field [0001] The invention relates to a baby stroller, in particular to a rear wheel rotation structure of the baby stroller. Background technique [0002] Existing strollers mainly include a foldable frame, a seat mechanism, a front wheel assembly, a rear wheel assembly, and a locking mechanism for locking the frame in an unfolded position. The vehicle frame includes side brackets located on the left and right sides, and the seat mechanism is arranged between the side brackets on both sides. The side brackets on each side include a front bracket, a push rod and a rear bracket. Folding, the rear support assembly that can be folded left and right is generally provided between the two rear supports, and the bottom support frame that can be folded left and right is provided between the two front supports and the two rear supports. Since the front wheel assembly and the rear wheel assembly are fixed on the front bracket and the rear bracket, after the whole vehicle is...
