Abstract
A foldable trolley includes a chassis frame, which includes a front wheel set and a rear wheel set between a slidable plate is arranged for driving the rear wheel set to collapse toward the front wheel set. The first frame is coupled to a first driver device and is mounted on the slidable plate. The second frame is coupled to a second driver device and connected to the first frame. The first driver device drives the first frame to bend toward the front wheel set and the first frame drives the slidable plate to move simultaneously so as to have the rear wheel set to collapse towards the front wheel set. The second driver device drives the second frame to bend toward the rear wheel set so as to achieve an effect of multiple-stage folding to effectively reduce the overall size after folding.
