rear door hinge assembly

Abstract

A novel back door hinge assembly comprises a back door hinge press-fitting bolt, wherein the back door hinge press-fitting bolt penetrates in the upper surface of a back door hinge fixing seat, and is pressed in the back door hinge fixing seat; the head of the back door hinge press-fitting bolt is fixed with the upper surface of the back door hinge fixing seat in a spot welding manner; the back door hinge press-fitting bolt penetrates in a back door hinge gasket; the back door hinge gasket is adhered to the lower surface of the back door hinge fixing seat; an inclined surface of a back door hinge swinging arm is arranged on the upper surface of the back door hinge fixing seat; back door hinge anti-attrition bushes are respectively arranged on two sides of the back door hinge fixing seat; a back door hinge connecting shaft sequentially penetrates in the back door hinge anti-attrition bushes with the symmetric structures, the back door hinge fixing seat and the back door hinge swinging arm and then is fixed in a riveted manner; the back door hinge anti-attrition bushes are made of powder metallurgy anti-attrition materials; the wall thickness of the back door hinge anti-attrition bushes is 2mm; and the back door hinge gasket is made of an asbestos-free material. The novel back door hinge assembly is reasonable in structure, and is beneficial to adjustment on gaps of a door of a vehicle and water leakage prevention. Moreover, the novel back door hinge assembly is applicable to a minibus.

Description

technical field [0001] The invention relates to a vehicle door hinge assembly, in particular to a rear door hinge assembly of a van. Background technique [0002] The rear door hinge assembly is one of the important components in the van door system. It is a key component connecting the body and the door, and is also the main force-bearing component of the door. The rear door opens and closes around the rear door hinge connecting shaft. At present, the rear door hinge assembly of Shenyang Jinbei Daishi van generally includes a rear door hinge fixing seat, a rear door hinge swing arm, a rear door hinge connecting shaft, a common bushing, and a rear door hinge press-fit bolt. The rear door hinge press-fit bolts currently used are easy to slip and cannot be pressed to the end, and the axial thrust can only be guaranteed by welding. In order to adjust the gap and level difference of the door, the rear door hinge assembly can only be forced to deform by external force, which inc...

AI Technical Summary

Problems solved by technology

In order to adjust the gap and surface difference of the car door, the rear door hinge assembly can only be deformed by external force, which increases the workload of the assembly workers for debugging. Due to the existence of stress concentration, the stress of the hinge assembly is released after a certain mileage of the car, and the The rear door assembly will fall off, and there will be problems such as uneven gap between the rear door and the side wall; the ordinary bushing has a thinner wall thickness, and the composite layer will fall off after long-term use, which will further cause the door gap to become larger and cause abnormal opening noise or Difficult, affecting the normal use of the rear door and reducing the service life
