The invention discloses a vehicle-mounted full-automatic retractable folding ladder which comprises a pair of parallelogram ladder assemblies, a pair of right-angle side plates, a plurality of steps, a pair of linear transmission mechanisms, a groove-shaped end panel, an electric linear motion module and an electric push rod. The electric linear motion module is located outside one ends of the pair of right-angle side plates and comprises a motor reducer combination, a transfer case and a pair of right-angle steering reduction gearboxes, the linear transmission mechanisms are arranged on the pair of right-angle side plates respectively, one ends of the linear transmission mechanisms are connected with one ends of the electric linear motion module respectively, and the other ends of the linear transmission mechanisms are fixedly connected with the other ends of the corresponding ejector rods respectively. The two ends of the electric push rod are hinged to the groove-shaped end panel and the middle of the side, close to the vehicle platform, of the parallelogram ladder frame correspondingly. According to the invention, the boarding stability and the long-term use reliability are improved, the installation space is saved, and the integration level of the whole vehicle is improved.
