The invention discloses a large armrest locking hinge for an automobile rear seat, which comprises a fixed shaft part and a movable bracket rotationally sleeved with the fixed shaft part, the fixed shaft part is provided with a folding limiting part and a use supporting part which are protruded outwards, the movable bracket is provided with a positioning shaft. The rotating stroke of the movable bracket is limited between the folding limiting part and the use supporting part by the positioning shaft; a main locking block is rotationally installed on the movable support, a first elastic element is assembled between the main locking block and the movable support, and when the positioning shaft moves to the inner side position of the folding limiting part, the first elastic element enables the main locking block to apply thrust to the folding limiting part so as to force the positioning shaft to be tightly attached to the folding limiting part. The large armrest locking hinge has the beneficial effect that the large armrest can be locked on the back row backrest in a zero-shaking-clearance mode.
