1. An energy storage travel suitcase comprises a suitcase body (1);

  • the front side and the rear side below the box body (1) are respectively provided with a front row of rollers (2 a) and a rear row of rollers (2 b);

    a pull rod (3) is also arranged in the box body (1);

    the method is characterized in that;

    a spring mechanism (4) is arranged above the rear row roller (2 b), and the spring mechanism (4) comprises a spring shaft (40) and a spring wound on the spring shaft;

    the spring shaft (40) is coupled with the wheel shaft (20) of the rear row of rollers (2 b) through a transmission mechanism;

    the transmission mechanism is a gear shifting gearbox mechanism (5) and comprises a gear shifting rod (51), and the gear shifting rod (51) can shift the wheel shaft (20) and the spring shaft (40) between three states of forward transmission, reverse transmission and decoupling;

    when the gear shift lever (51) is in a neutral state and the wheel shaft (20) and the spring shaft (40) are decoupled, a brake block fixed relative to the gear shift lever (51) brakes the spring shaft (40) so as to store the potential energy of the spring;

    the wheel shaft (20) is matched with the rear row roller (2 b) through a one-way bearing, so that when the rear row roller (2 b) rolls in the dragging process of the box body by the pull rod, namely when the rear row roller (2 b) rolls in the positive direction, the wheel shaft (20) is driven to rotate by the rear row roller (2 b), and the clockwork spring is tightened by the wheel shaft (20) through a transmission mechanism;

    when the rear row roller (2 b) rolls in the opposite direction, the wheel shaft (20) does not follow the rear row roller (2 b) in a free state.
