Abstract

The invention discloses a postpositioned planetary gear structure used for a baby carrier, which is characterized in that the two sides of the planetary gear central shaft are respectively provided with a cross four planet carrier which is in a fan shape and is evenly distributed with fins; a planetary gear is arranged at the end part of each fin, is flexibly connected with the fin through a planetary gear shaft, and adopts a cross four planet carrier; and an anti-vibration device is arranged in a vertical frame tube to lead that the baby carrier not only can be suitable for more bumpy road surfaces, but also can climb up steps, thus having good practicability. The postpositioned planetary gear structure of the invention is improved aiming at a rear-wheel structure of the baby carrier, and has prominent substantive features and obvious improvement compared with the prior art.
