Abstract

The utility model relates to a supporting plate structure of a back door outer plate and belongs to the technical field of auto parts. The supporting plate structure of the back door outer plate comprises a supporting plate body, wherein a first welding edge is arranged on one side of the supporting plate body and is folded outwards, and a second welding edge is arranged on the other side of the supporting plate body and is folded inwards. The supporting plate structure of the back door outer plate has the advantages that the rigidity and strength of the back door outer plate are greatly improved, and the turning and bending rigidity and mode of a back door are greatly improved.

Description

A kind of tailgate outside plate supporting plate structure
Technical field
The utility model belongs to technical field of automobile parts, is specifically related to a kind of tailgate outside plate supporting plate structure.
Background technology
In order to strengthen local stiffness and the intensity of automobile back-door outer panel, generally between tailgate outside plate and tailgate back veneer, design some bracing frames, this bracing frame is extended to outside plate and is formed by the backward outside plate direction of the local panel beating bending of tailgate back veneer, play the effect of supporting tailgate outside plate, and be usually used in the less and easy stamping forming situation of back veneer of tailgate outside plate Support Position back veneer and outside plate cavity clearance, and being connected of back veneer and outside plate realized by welding in the one end that extends to outside plate.But, in tailgate back veneer and the larger situation of outside plate cavity clearance, this can cause the long and complex structure of the bracing frame extending out on back veneer, thereby the press depth that causes back veneer crosses dark or stamping quality is poor and cannot global formation, enable punch forming, long support for the castering action of outside plate Local Property a little less than, this has improved the performance requriements of tailgate miscellaneous part indirectly, increase design difficulty and cost, sometimes must sacrifice weight in the hope of reaching tailgate performance objective.
Utility model content
The purpose of this utility model is exactly the defect for prior art, outside meeting stamping quality and raising tailgate, under panel stiffness, intensity prerequisite, by tailgate back veneer extending bracket structure is improved, provides a kind of tailgate outside plate supporting plate structure.
The technical solution adopted in the utility model is: it comprises stay bearing plate body, and described stay bearing plate body one side is provided with the first welding edge, and described the first welding edge outwards turns down; Described stay bearing plate body opposite side is provided with the second welding edge, and described the second welding edge inwardly turns down.
Further, described the first welding edge and the welding of tailgate back veneer, described the second welding edge and the welding of tailgate outside plate.
Further, on described stay bearing plate body, have tailgate wire harness locating fastener mounting hole.
Further, on described the first welding edge, have for the auxiliary hole with the welding of tailgate back veneer.
Further, described stay bearing plate is provided with horizontal " Z " shape reinforced rib that extends to opposite side edge from described stay bearing plate surface one lateral edges.
Further, described stay bearing plate body is provided with lightening hole.
Further, the thickness of described stay bearing plate body is 0.7mm~1.5mm.
The utility model will play a multiplier effect to the improvement of rigidity, intensity and the tailgate torsion of lifting tailgate outside plate, bending stiffness, mode.
Accompanying drawing explanation
Fig. 1 the utility model structural representation;
Fig. 2 is the utility model lateral plan;
Fig. 3 is the utility model scheme of installation.
In figure: 1-stay bearing plate body; The 2-the first welding edge; The 3-the second welding edge; 4-tailgate wire harness locating fastener mounting hole; 5-auxiliary hole; 6-lightening hole; 7-reinforced rib; 8-tailgate back veneer; 9-tailgate outside plate.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form and limit the utility model.
As shown in Fig. 1-Fig. 3, the utility model comprises stay bearing plate body 1, and described stay bearing plate body 1 one sides are provided with the first welding edge 2, and described the first welding edge 2 outwards turns down; Described stay bearing plate body 1 opposite side is provided with the second welding edge 3, and described the second welding edge 3 inwardly turns down.Described the first welding edge 2 and 8 welding of tailgate back veneer, described the second welding edge 3 and 9 welding of tailgate outside plate.On described stay bearing plate body 1, have tailgate wire harness locating fastener mounting hole 4.On described the first welding edge 2, have for the auxiliary hole 5 with 8 welding of tailgate back veneer.Described stay bearing plate is provided with horizontal " Z " shape reinforced rib 7 that extends to opposite side edge from described stay bearing plate surface one lateral edges.Described stay bearing plate body 1 is provided with lightening hole 6.The thickness of described stay bearing plate body 1 is 0.7mm~1.5mm.
The content that this specification sheets is not described in detail belongs to the known prior art of professional and technical personnel in the field.
