Abstract

The invention discloses a self-limiting car door hinge, which comprises a movable leaf fixedly connected with the car door and a fixed leaf fixedly connected with the vehicle body. A spring is provided between the limiting plate and the movable page, and a roller is provided on the fixed page. The side edge of the limiting plate away from the spring is in contact with the roller. a limiting arc. Also disclosed is an automobile, including the above-mentioned self-limiting vehicle door hinge. Its structure is simple, so that the car door has multiple opening limit functions, occupies a small space, and is convenient for arrangement.

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...
