TECHNICAL FIELD
[0001] The utility model belongs to the technical field of door hinge, and relates to an automobile door hinge, in particular to an automobile door hinge mounting structure. BACKGROUND
[0002] The hinge is a device for determining the relative position of the door and the vehicle body and controlling the movement track of the door, and is a general term of components capable of rotating around the same axis in the up-down direction and combined with each other. The hinge can be composed of a movable assembly or a foldable material. The door hinge is a component for connecting the door and the vehicle body and enabling the relative rotating movement of the door and the vehicle body.
[0003] Through retrieval, a door hinge mounting structure is disclosed in Chinese patent document CN202321891332.4 and CN220487357U. The door hinge mounting structure includes a threaded plate and a positioning mounting plate capable of being connected and mounted with the automobile A-pillar. The threaded plate is provided with a bushing. The positioning mounting plate is provided with a plug-in plate capable of penetrating the bushing. A spring buckle is clamped between the end of the plug-in plate and the threaded plate. The door hinge is arranged on the side of the positioning mounting plate away from the threaded plate and is provided with a bolt capable of penetrating the positioning mounting plate and being screw-connected with the threaded plate.
[0004] The door hinge mounting structure disclosed in the patent is pressed by the spring buckle and the positioning mounting plate, thereby achieving the flexible adjustment of the threaded plate and the door hinge mounting, avoiding welding and offset holes. However, the single-skeleton door hinge currently used has limited strength, which causes the door to sag and loosen after long-term use. Moreover, the current door hinge needs to be separately provided with a limiter to facilitate the opening of the user, which increases the mounting structure of the door and is inconvenient for the later maintenance and repair.
