Description

Front shroud assembly and car

Technical Field

The utility model belongs to the technical field of automobile parts, concretely relates to front shroud assembly and car.

Background

At present, the edge connection of the inner plate and the outer plate of the front cover of the automobile mainly adopts a process of die buckling or roller edge, and epoxy edge folding glue is coated on the outer plate before edge folding. However, the front cover welding assembly does not have the function of connecting the inner plate and the outer plate of the front cover before coating and baking due to the fact that the epoxy hemming adhesive is not cured, the front cover welding assembly is subjected to impact force in the process of electrophoresis liquid gravity and liquid flowing in the electrophoresis process, meanwhile, the inner plate and the outer plate of the front cover are in rigid connection without welding spots and the like, the local torsion of the front cover is caused to be unfavorable and deformed by more than 2mm, the appearance of the whole vehicle is seriously influenced, and particularly, the deformation of a region where the front cover is matched with a headlamp is serious. As shown in fig. 1, a front hood outer panel 1 is connected to a front hood inner panel 2 by a die fastening or roll hemming process, and the front hood inner panel 2 and a front hood hinge 3 are connected to a vehicle body by bolts. Because the front cover inner plate 2 is connected with the front cover outer plate 1 only by the edge covering, the capability of resisting deformation before the sealant 4 and the epoxy hemming adhesive 5 are not cured is poor, the requirement on production and manufacturing is high, and the appearance stability is poor.

Therefore, there is a need for a new front cover assembly and vehicle.

Disclosure of Invention

The utility model aims at providing a front shroud assembly and car to solve the big problem of warping behind the front shroud welding assembly application.

In a first aspect, the front cover assembly of the present invention comprises a front cover inner plate and a front cover outer plate, wherein an edge of the front cover outer plate is bent to form a hemming groove; the edge of the front cover inner plate is positioned in the edge covering groove and is sealed by epoxy edge folding glue and sealing glue; at least one part of the edge of the front cover inner plate is provided with an inward arc bulge, and the front cover inner plate is welded with the inner side surface of the edge of the front cover outer plate through the arc bulge.

Further, inward circular arc bulges are arranged at least at the position matched with the headlamp and the position matched with the fender on the edge of the front cover inner plate.

Further, the edge covering groove is a U-shaped groove.

In a second aspect, an automobile, adopt like the utility model discloses in the front shroud assembly.

The utility model has the advantages of it is following: the arc protrusions of the front cover inner plate and the inner side face of the edge of the front cover outer plate are in rigid connection through welding, before the sealant and the epoxy edge folding adhesive are not cured, the front cover assembly can resist the impact force of the front cover assembly in the electrophoresis process caused by the gravity of electrophoresis liquid and the liquid flowing process, and the problem of large local deformation of the front cover assembly is solved. In addition, the utility model discloses still have that the appearance is pleasing to the eye, technology is exquisite, simple structure, dependable performance and characteristics such as with low costs.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

In the present embodiment, as shown in fig. 3 and 4, a front hood assembly includes a front hood inner panel 2 and a front hood outer panel 1, wherein an edge of the front hood outer panel 1 is bent to form a hemming groove; the edge of the front cover inner plate 2 is positioned in the edge covering groove and sealed by epoxy edge folding glue and sealant 4. At least one part of the edge of the front cover inner plate 2 is provided with an inward (i.e. towards the cabin) arc protrusion 2a, and the front cover inner plate 2 is welded with the inside surface 1a of the edge of the front cover outer plate 1 through the arc protrusion 2 a.

As shown in fig. 4, in the present embodiment, the edge of the cowl inner 2 is provided with an inward rounded protrusion 2a at least at a headlight engagement position and a fender engagement position. Of course, the circular arc protrusion 2a may be provided at other positions than these two positions according to actual conditions.

As shown in fig. 4, in this embodiment, the edge covering groove is a U-shaped groove.

As shown in fig. 4, in the present embodiment, the circular arc protrusion 2a is formed by punching.

As shown in fig. 5 and 6, a loop is formed by the conductive electrode 6, the arc protrusion 2a on the front cover inner panel 2, the hemming inner side 1a of the front cover outer panel 1, and the resistance spot welding electrode 7, the arc protrusion 2a on the front cover inner panel 2 and the hemming inner side 1a of the front cover outer panel 1 are partially in surface contact, and the welding spot 9 is formed between the arc protrusion 2a of the front cover inner panel 2 and the hemming inner side 1a of the front cover outer panel 1 via the resistance spot welding electrode 7. The clamp supporting surface 8 supports the front cover outer plate 1, the clamp supporting surface 8 is made of insulating resin and is not conductive, a loop cannot be formed between the outer side surface of the front cover outer plate 1 and the arc protrusions 2a of the front cover inner plate 2, and the outer side surface of the front cover outer plate 1 cannot have appearance defects in the welding process of the arc protrusions 2a of the front cover inner plate 2 and the edge-covering inner side surface 1a of the front cover outer plate 1. Before the front cover assembly is subjected to electrophoresis, the front cover outer plate 1 and the front cover inner plate 2 are welded and then connected with a vehicle body through the front cover hinge 3, before the sealant 4 and the epoxy hemming adhesive 5 are not cured, the circular arc protrusions 2a of the front cover inner plate 2 and welding spots 9 between the hemming inner side surfaces 1a of the front cover outer plate 1 are in rigid connection, the front cover assembly can be resisted by impact force generated in the electrophoresis process of electrophoresis liquid gravity and liquid flowing, and the problem of local deformation of the front cover assembly is solved.

In this embodiment, the front cover assembly in this embodiment is adopted in the automobile.
