A VAN vehicle D-pillar back door hinge installation structure and method

Abstract

This invention discloses a hinge installation structure and method for the tailgate D-pillar of a van, belonging to the field of automobile manufacturing. The hinge installation structure includes a D-pillar, with a hinge support assembly fixed to the inner wall of the D-pillar. The hinge support assembly includes a hinge support ring, with a mounting plate fixed to the hinge support ring. The D-pillar has a first through hole, and the mounting plate has hinge mounting holes corresponding to the through hole. The hinge installation method includes first welding the mounting plate to the hinge support ring to form the hinge support assembly, then welding the hinge support assembly to the inner wall of the D-pillar, and finally welding the outer plate of the D-pillar to the inner plate of the D-pillar via a D-pillar connecting plate to form the D-pillar. This invention, by installing the hinge support assembly to the inner wall of the D-pillar, effectively increases the stiffness and fatigue resistance of the tailgate hinge installation structure, and also significantly improves the surface stiffness of the D-pillar, thereby enhancing the overall structural stiffness of the D-pillar, and consequently improving the overall vehicle body performance and reliability.

Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing, specifically to a VAN vehicle D-pillar tailgate hinge installation structure and method. Background Technology

[0002] With the rapid development of the times, the market demand for unibody light passenger vehicles (VANs) is increasing, making VANs one of the key vehicle types that automakers are vying to develop. As a type of vehicle that combines passenger and commercial functions, VANs often feature double-opening rear doors, and the structure of these rear doors includes a tailgate hinge mounting structure. In order to simultaneously meet the requirements of passenger and commercial use and improve the durability and reliability of the vehicle body, higher requirements need to be placed on the rigidity of the tailgate hinge mounting structure on the D-pillar of the VAN.

[0003] The existing D-pillar tailgate hinge installation structures of vans mostly suffer from insufficient rigidity at the tailgate hinge installation point and poor fatigue resistance. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a VAN (van) D-pillar tailgate hinge installation structure and method. This invention offers the advantage of significantly improved stiffness and fatigue resistance at the tailgate hinge mounting point compared to existing hinge installation structures.

[0005] To achieve the above objectives, this invention designs a hinge mounting structure for the rear door of a VAN (Vehicle) on the D-pillar. A hinge support assembly is fixed to the inner wall of the D-pillar. The hinge support assembly includes a hinge support ring, on which a mounting plate is fixed. The D-pillar has a first through hole, and the mounting plate has hinge mounting holes corresponding to the through hole.

[0006] Preferably, the hinge support ring includes a vertically arranged rectangular plate, with a horizontally arranged upper annular plate and a lower annular plate fixed at both ends of the rectangular plate, and the upper annular plate and the lower annular plate are fixed to the inner wall of the D-pillar.

[0007] Preferably, the top edge of the upper annular plate is provided with a first fixing plate, a second fixing plate, a third fixing plate, and a fourth fixing plate welded to the inner wall of the D-pillar at intervals; the bottom edge of the lower annular plate is provided with a fifth fixing plate, a sixth fixing plate, a seventh fixing plate, and an eighth fixing plate welded to the inner wall of the D-pillar at intervals.

[0008] Preferably, a D-column support convex plate is fixed between the rectangular plate and the inner wall of the D-column.

[0009] Preferably, the protrusion of the D-column support plate is provided with an expanding adhesive layer.

[0010] Preferably, the D-pillar includes an outer D-pillar panel and an inner D-pillar panel, which are fixedly connected by a D-pillar connecting plate, and the outer D-pillar panel is provided with a through hole.

[0011] Preferably, a reinforcing plate is attached to the mounting plate, and the reinforcing plate is provided with a second through hole corresponding to the mounting hole.

[0012] This invention also designs a method for installing a VAN vehicle D-pillar tailgate hinge, the method being implemented based on the aforementioned VAN vehicle D-pillar tailgate hinge installation structure, and comprising the following steps:

[0013] Step S1: Weld the mounting plate to the hinge support ring via the first fixing plate, second fixing plate, third fixing plate, fifth fixing plate, sixth fixing plate, seventh fixing plate and welding plate on the hinge support ring; weld the D-pillar support convex plate to the rectangular plate and assemble them into a hinge support assembly.

[0014] Step S2: Weld the hinge support assembly to the inner wall of the D-pillar, fix the hinge support assembly to the inner wall of the inner panel of the D-pillar through the fourth fixing plate and the eighth fixing plate, and weld the D-pillar support protrusion to the inner wall of the outer panel of the D-pillar.

[0015] Step S3: Weld the outer panel of the D-pillar to the inner panel of the D-pillar using the D-pillar connecting plate to form the D-pillar.

[0016] Preferably, in step S1, a reinforcing plate is welded to the inner wall of the mounting plate to align the mounting hole with the second through hole.

[0017] Preferably, in step S1, an expanding adhesive is pre-applied to the protrusion of the D-pillar support plate.

[0018] The beneficial effects of this invention are:

[0019] This invention uses a hinge support assembly to install the hinge onto the inner wall of the D-pillar. This structure effectively increases the rigidity and fatigue resistance of the tailgate hinge installation structure, and also significantly improves the surface rigidity of the D-pillar, thereby enhancing the overall structural rigidity of the D-pillar, which in turn improves the overall vehicle body performance and reliability.
