Integrated vehicle trunk lid hinge reinforcing plate support structure

Abstract

The invention discloses an integrated vehicle trunk lid hinge reinforcing plate support structure and belongs to the field of vehicle trunk lid systems. The integrated vehicle trunk lid hinge reinforcing plate support structure is used for increasing the rigidity of a trunk lid outer plate and a hinge assembly mounting plate and at least comprises an integrally-formed hinge reinforcing plate support assembly which is welded on a trunk lid inner plate one time. The hinge reinforcing plate support assembly is further provided with turnup edges and a reinforcing rib which vertically penetrates through the support assembly, a gluing groove is additionally formed in a position, contacted with an outer plate, of the hinge reinforcing plate support assembly, and therefore the trunk lid inner plate and the trunk lid outer plate are connected, the rigidity performance of the vehicle trunk lid outer plate and the hinge assembly mounting plate is enhanced, and the rigidity of pointed corners of a trunk lid is greatly increased. The number of parts is reduced, the problem that influences are accumulated due to manufacturing errors of two parts is avoided, welding machining precision is more reliable, the integrated vehicle trunk lid hinge reinforcing plate support structure can be matched with appearance more easily, total white vehicle body weight is reduced, positioning and welding processes are correspondingly reduced, and working hours and manufacturing cost are saved.

Description

technical field [0001] The invention relates to the field of automobile trunk lid systems, in particular to an integrated automobile trunk lid hinge reinforcement plate support structure. Background technique [0002] The trunk lid system mainly includes the trunk lid assembly, hinge assembly and other assembly accessories. The trunk lid assembly is formed by bonding the trunk lid inner panel assembly with the outer panel body. [0003] At present, most of the trunk lids of automobiles form sharp corners near the rear windshield glass on both sides of the outer panel of the trunk lid due to the influence of the shape and the arrangement of the hinges, so that the stiffness here is insufficient and easy to deform. In order to ensure its rigidity requirements, a bracket for supporting the outer panel of the trunk lid is usually added near the hinge reinforcement plate.

AI Technical Summary

Problems solved by technology

[0004] figure 1 It is a schematic diagram of the bracket structure supporting the outer panel of the trunk lid in the prior art. The bracket adopts a split hinge reinforcement plate 1 and an outer panel support plate 2, and these two parts are assembled together. This structure requires two separate designs. Parts, when installing, firstly weld the hinge reinforcement plate 1 on the inner panel 3 of the trunk lid, and then weld the outer plate support plate 2 on the hinge reinforcement plate 1 with three layers of solder joints, which not only wastes man-hours but also causes two weldings to occur. The accumulation of errors affects the machining accuracy and leads to the increase of cost, positioning and welding process
