• a coupler mounting base fixed to the vehicle head;
• and
• a coupler fixedly mounted to the coupler mounting base,
• wherein the coupler assembly further comprises a supporting component and a rotating member both provided at each of two sides of the coupler mounting base;
• the rotating member has one end rotatably connected to a lower end of the supporting component, and a rotation center of this end is arranged horizontally and perpendicular to a length direction of the rail vehicle, and the rotating member has another end hinged to an upper end of the coupler mounting base;
• and
• the coupler assembly is configured such that in an initial state, the coupler mounting base is fixedly connected to the supporting component, and a hinge point where the rotating member is hinged to the coupler mounting base is located above a rotational connection point where the rotating member is rotatably connected to the respective supporting component.
