Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

A vehicle door hinge integrated with a limit structure as shown in fig. 1 to 5 includes a female hinge 1, a hinge shaft 3 having a central axis extending in an up-down direction, and a male hinge 2 hinged to the female hinge 1 through the hinge shaft 3; a through hole 9 penetrating through the female hinge 1 along the left-right direction is formed in the female hinge 1, a limiting ejector rod 10 is assembled at the left part of the through hole 9 in a sliding fit mode, a second locking bolt 12 is assembled at the right part of the through hole 9 in a thread fit mode, a spring 11 tightly pushing the limiting ejector rod 10 to the left is arranged in the through hole 9, and the right end of the spring 11 abuts against the second locking bolt 12; the left end of the limiting ejector rod 10 is supported on the side wall of the male hinge 2, a limiting curved surface 13 which is in contact with the left end of the limiting ejector rod 10 is arranged on the side wall of the male hinge 2, a plurality of limiting grooves 15 which are used for allowing the left end of the limiting ejector rod 10 to slide in and out are formed in the limiting curved surface 13, and the plurality of limiting grooves 15 are distributed along the circumferential direction of the hinged shaft 3. The limiting curved surface 13 is arranged on the side wall of the male hinge 2, so that the limiting curved surface 13 can be formed in an extrusion molding mode when the male hinge 2 is processed, and the surface finish and the wear resistance of the limiting curved surface 13 can be improved through machining, surface polishing and quenching in the subsequent process. When the automobile door limiting device is used, the female hinge 1 is fixedly connected to an automobile body, the male hinge 2 is fixedly connected to an automobile door, the female hinge 1 can rotate around the hinged shaft 3 in the process of opening and closing the automobile door, the limiting curved surface 13 can rotate along with the female hinge 1, and the left end of the limiting ejector rod 10 can slide into and slide out of the limiting groove 15. When the left end of the limit ejector rod 10 slides into the limit groove 15, the left end of the limit ejector rod 10 tightly pushes the limit groove 15 to the left, so that the rotation of the female hinge 1 can be hindered, the opening degree of the vehicle door is limited, a gear feeling is formed, and the vehicle door can be continuously pushed to enable the left end of the limit ejector rod 10 to slide out of the limit groove 15 through the extrusion of the limit curved surface 13. The limitation of a plurality of opening degrees of the vehicle door can be realized by arranging a plurality of limiting grooves 15.
