Vehicle door hinge and vehicle door installing structure adopting the same

Abstract

The invention discloses a vehicle door hinge and a vehicle door installing structure adopting the same. On the premise of guaranteeing the attractiveness, reliability and service life of the hinge, the assembling efficiency of a vehicle door is effectively improved. The vehicle door hinge comprises a hinge shaft, a rotary plate and a fixed plate, the hinge shaft comprises a cylindrical body, and a protruding annular flange surface is arranged in the middle of the body; the hinge shaft passes through a shaft hole of the rotary plate and a shaft hole of the fixed plate, and the rotary plate and the fixed plate are located at the two sides of the annular flange surface respectively; an anti-disconnection piece used for preventing the rotary plate from being disconnected is arranged at one end of the hinge shaft; a through hole facing toward the hinge shaft perpendicularly is formed in the fixed plate, a locking pin is installed inside the through hole, and one end of the locking pin abuts against the hinge shaft, so that the fixed plate is fixed to the hinge shaft relatively. According to the vehicle door hinge, by means of the locking pin which is screwed up in the lateral direction, a hinge assembly can be divided into a rotary plate sub-hinge assembly which is composed of the hinge shaft and the rotary plate and the fixed plate, and therefore the vehicle door can be separated from a framework.

Description

technical field [0001] The invention belongs to the field of auto parts, in particular to a car door hinge and a car door installation structure using the hinge. Background technique [0002] The door hinge is one of the most critical components in the car opening and closing system. It is an auto part that connects the door and the body and ensures its relative position. At present, traditional fixed leaf boards and rotating leaf boards are riveted together through hinge shafts or installed together through special-shaped nuts and hinge shafts with their own threads. After the hinges are installed, they cannot or are difficult to disassemble on the assembly line. The specific reasons are as follows: the door assembly is difficult to disassemble and the efficiency is low; , the appearance still has defects, and the working hours are long and the operation is inconvenient. Now, with the improvement of production efficiency requirements, the assembly shop needs to assemble t...

Problems solved by technology

After the hinges are installed, they cannot or are difficult to disassemble on the assembly line. The specific reasons are as follows: the door assembly is difficult to disassemble and the efficiency is low; , the appearance still has defects, and the working hours are long and the operation is inconvenient

Now with the improvement of production efficiency requirements, the assembly workshop needs to assemble the side door and the frame on a separate assembly line, so the traditional hinge is difficult to meet the requirements of the current production process
