Car door hinge structure with limiting function

Abstract

The invention discloses a car door hinge structure with a limiting function, and belongs to the technical field of automobile part manufacturing. The car door hinge structure comprises a car body hinge piece and a car door hinge piece, a lower through hole is formed in the car body hinge piece,limiting protrusions are arranged on one side of the upper end face of the car body hinge piece, an upperthrough hole is formed in the car door hinge piece, a plurality of limiting holes are formed around the upper through hole, a limiting rod is arranged in each limiting hole, the upper through hole and the lower through hole are formed correspondingly, a bolt body is arranged in the upper through hole and the lower through hole, a top nut is arranged at the upper end of the bolt body, a bottom nutis arranged below the bolt body, and the bolt body is connected between the car body hinge piece and the car door hinge piece through the top nut and the bottom nut. The structure is novel, the working principle is clear, limiting between the car door hinge piece and the car body hinge piece is formed due to the mutual effect between the limiting rods and the limiting protrusions, the car door hinge can meet the limiting protection function, and the service life of car doors and car door hinges can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of auto parts manufacturing, and relates to a car door hinge structure, in particular to a car door hinge structure with a position-limiting function. Background technique [0002] As an important part connecting the door and the body, its main function is to ensure and maintain the position of the door relative to the body, and to ensure and facilitate the opening and closing of the door. In addition to satisfying the necessary functional functions, hinges also need to consider issues such as ergonomics, modeling joints, and door sagging. [0003] The door hinges can be divided into open hinges and concealed hinges. Concealed hinges are more commonly used, and there are two types of movement: inward opening and outward opening. According to the hinge structure, it can be divided into stamping type, welding type, fixed type, integral type, detachable type, etc. There are generally three connection methods ...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the present automobile door hinge shaft pin which is made of ordinary steel structure bolts or riveting, which only has the function of connecting and carrying the car door, and does not have the function of limiting the position. Generally, the limit of the car door needs to be limited by a limiter. When the positioner is faulty or damaged, due to the loss of the limit function, the door may be rotated too far and cause the door to be bumped or damaged. A door hinge structure with a limit function is proposed, which can make the door hinge meet the limit protection function. Extends the life of automotive doors and door hinges
