Description

technical field [0001] The invention relates to a car door hinge, in particular to a self-limiting car door hinge and a car. Background technique [0002] The door hinge connects the door and the side wall to ensure the opening and closing of the door. The existing car door is generally arranged with hinges and stoppers. The stopper is used to limit the opening angle of the door. Safety, and avoiding interference or even damage caused by over-opening the door. The arrangement of the limiter makes it necessary to set the installation point for the door, and the installation space is relatively large, which affects the appearance quality to a certain extent. It is greatly affected by the structure and space, especially for profile frame doors and body, it is difficult to have space for arranging stoppers. Therefore, it is necessary to improve the existing limiter and integrate it into the hinge, so as to save installation space and have better appearance quality. [0003] C...
