The invention discloses a large-opening-angle self-limiting back door hinge, and belongs to the field of automobile manufacturing. Comprising a base installed on an automobile body, a main rotating arm is hinged to the base, and an auxiliary rotating arm is hinged to the other end of the main rotating arm and fixed to an automobile back door. A cavity is formed in the middle of the main rotating arm, a connecting rod is arranged in the cavity, the two ends of the connecting rod are hinged to the base and the auxiliary rotating arm respectively, a limiting roller assembly is arranged at the end, away from the auxiliary rotating arm, of the main rotating arm, a C-shaped torsion rod spring is arranged on the base, and the tail end of the C-shaped torsion rod spring movably abuts against the top of the limiting roller assembly. The limiting roller assembly and the C-shaped torsion rod spring enable the automobile back door to be limited at one gear or multiple gears when the automobile back door is opened and closed. According to the invention, one or more groups of limiting rollers are arranged on the main rotating arm, and the relative positions of the limiting rollers are calculated, so that the limiting rollers can be subjected to one-gear or multi-gear limiting at the required positions of the vehicle door.
