Description

Side panel assembly {SIDE PANEL ASSEMBLLY}

The present invention relates to a side panel assembly, and more particularly, to a side panel assembly having a welded rigid reinforcement structure of a side inner panel and a side outer panel welded and fixed to a roof panel.

In general, the vehicle side panel assembly 1 as shown in FIG. 1 has a side outer panel 11 and a side inner panel (not shown) assembled, and an upper side thereof is welded to the roof panel (not shown) of the vehicle body. do.

The side panel assembly 1 has a side outer panel 11 and a side inner panel 21 formed therebetween by mutual spot welding at both ends thereof through the flange portion F at both ends thereof, as shown in FIG. 2. Are bonded.

A space S is formed between the side outer panel 11 and the side inner panel 21, and the reinforcement panel 31 resembling the shape of the side outer panel 11 is additionally formed in the space S. This increases the rigidity of the vertical load of the connection with the roof panel (not shown).

At this time, both ends of the reinforcement panel 31 are joined to each other by spot welding integrally between the side outer panel 11 and the side inner panel 21 via the flanges F.

However, in the side panel assembly 1 according to the related art as described above, the side outer panel 11, the side inner panel 21, and the reinforcing panel 31 overlap each other in three layers through the flange portion F at each end. As the spot welding proceeds, the weld strength of the joint is weak, and the number of parts increases as a separate reinforcement panel 31 is additionally configured to reinforce rigidity.

Therefore, the present invention has been invented to solve the above disadvantages, the problem to be solved by the present invention can reinforce the weld stiffness of the side inner panel and side outer panel welded and fixed to the roof panel without a separate reinforcement panel. To provide a side panel assembly.

The side panel assembly according to the present invention for realizing the technical problem as described above is composed of a side outer panel and a side inner panel is welded and fixed to the roof panel in the side panel assembly bonded to each other at both ends, the side outer panel is An outer curved portion forming an outer surface is formed, and an outer flange for spot welding is formed at both ends, and the side inner panel forms an inner curved portion forming an inner surface to form a space portion between the side outer panel. In both ends, inner flanges are spot welded to both outer flanges of the side outer panel, and the inner flanges of both ends are bent with their respective ends extending and bent, and the reinforcing flanges overlapping with each inner flange are integrally formed. Three-ply with the both out flanges Overlap splicing.

The reinforcing flange may be molded to be interposed between the outer flange and the inner flange.

In addition, the reinforcing flange may be molded to be joined to the outer end surface of the inner flange to be bonded to the outer flange.

In addition, the three-ply overlap joint may be made of a spot weld joint.

In addition, the three-ply bonding may be made of laser welding.

According to the side panel assembly of the present embodiment, a reinforcing flange extending to the inner flange is additionally formed in the flange portion for joining the side inner panel and the side outer panel welded and fixed to the roof panel without a separate reinforcing panel, thereby forming a vertical direction of the roof panel. Stiffness to load can be reinforced.

In addition, the separate reinforcement panel can be deleted to reduce the number of components, thereby reducing the part molding process has an advantage in improving productivity.

FIG. 2 is a cutaway perspective view of a side panel assembly according to the prior art along line AA of FIG. 1.
3 is a cutaway perspective view of a side panel assembly according to an embodiment of the present invention along line AA of FIG. 1.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

However, in describing the configuration of the present invention, the same components as those in the prior art will be described with the same reference numerals.

3 is a cutaway perspective view of a side panel assembly according to an embodiment of the present invention taken along line A-A of FIG.

Referring to FIG. 3, the side panel assembly 1 according to the present exemplary embodiment includes a side outer panel 11 and a side inner panel 21 welded and fixed to a roof panel (not shown), and flange parts F at both ends thereof. ) And welded together.

The side outer panel 11 forms an outer curved portion 11a forming an outer surface, and forms an outer flange F1 for spot welding at both ends.

In addition, the side inner panel 21 forms an inner curved portion 21a forming an inner surface thereof to form a space S between the side outer panel 11.

The side inner panel 21 forms inner flanges F2 which are spot welded to both ends of the outer flange F1 of the side outer panel 11 at both ends thereof.

At this time, the both ends of the inner flange (F2) is formed in the reinforcement flange (F3) integrally to be in contact with the cross section of each inner flange (F2) in a state in which the front end is extended and bent, respectively.

The side outer panel 11 and the side inner panel 21 are joined to the three-ply spot welding at the flange portion F at both ends.

That is, both inner flanges F2 of the side inner panel 21 correspond to the outer flanges F1 of the side outer panel 11, and between each of the outer flanges F1 and the inner flange F2. In each of the inner flange (F2) is extended to each of the reinforcing flanges (F3) that are bent inward to form a three-ply spot welded overlapping state.

In the present embodiment, the reinforcing flange (F3) is extended to the inner flange (F2) so as to be interposed between the outer flange (F1) and the inner flange (F2), but is not limited thereto, and the outer flange (F1) and It may be molded to be joined to the outer end surface of the inner flange (F2) to be joined.

In addition, in the present embodiment, spot welding welding is applied as a three-ply bonding, but is not limited thereto, and laser welding may be applied.

Therefore, in the side panel assembly 1 having the above-described configuration, the flange portion F, which is a welded portion of the side inner panel 21 and the side outer panel 11, which is welded and fixed to the roof panel, may be formed without a separate reinforcement panel. The reinforcing flange F3 extending to the inner flange F2 serves to reinforce the rigidity against the vertical load of the roof panel.

In addition, the side panel assembly 1 according to the present embodiment can delete a separate reinforcement panel to reduce the number of components, thereby reducing the part forming process.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Various modifications and variations are possible within the scope of the appended claims.
