Problems solved by technology

In this process, the screw 103 of the car door hinge needs to be tightened repeatedly, which will damage the paint surface of the screw 103 surface; for aesthetics and to avoid rust, a plastic cover 104 needs to be installed on the screw 103. The color of the plastic cover 104 is usually single black, which will The color of the hinge and the body is inconsistent, which affects the visual effect and reduces the delicacy of the product; and the plastic cover 104 is easy to age and fall off, causing the screws 103 to rust and other problems

Abstract

The invention discloses a hinge and an automobile, and relates to the technical field of hinges. The hinge comprises a first connecting piece, a pin shaft and a second connecting piece, wherein the pin shaft comprises a rotating part and a dismounting part, the rotating part is rotationally connected with the first connecting piece, and a first clamping groove is formed in the periphery of the dismounting part; and a connecting hole which is matched with the dismounting part in a sleeving mode is formed in one end of the second connecting piece, a locking hole is formed in the hole wall of theconnecting hole, a locking pin is arranged in the locking hole in a sliding mode, a first clamping block matched with the first clamping groove is arranged at one end of the locking pin, a spring isarranged at the other end of the locking pin, an end cover is arranged at the end, far away from the connecting hole, in the locking hole, and the end cover can block the spring and the locking pin inthe locking hole. The hinge has an automatic locking function, and a screw does not need to be screwed when the pin shaft and the second connecting piece are assembled and disassembled.

Description

technical field [0001] The invention belongs to the technical field of hinges, and more specifically relates to a hinge and an automobile. Background technique [0002] With the development of the automobile industry, it has made rapid progress, but the competition in the industry is also unprecedentedly fierce; there are higher requirements for the appearance, performance, quality and cost of automobiles. [0003] The car door hinge is the most basic and very important part of the car body. In recent years, due to the requirements for appearance and quality of opening and closing doors, most OEMs have applied steel hinges. Its advantages are small size and good rigidity. After the on-board electrophoresis treatment, the body and door panels can be disassembled in the assembly workshop. However, tools need to be used to repeatedly rotate the fixing screws during disassembly, which will cause damage to the paint surface of the screws and affect the door. Hinge quality. [...
