The present invention relates to a dash panel and a center floor joining structure of a car, and in particular, to form a reinforcement structure of a box-shaped cross section at a joining part, and to devise a lateral rigidity of the vehicle body. It relates to a junction structure.

As shown in FIG. 1, the body panel structure of a passenger car includes a center floor panel 10, a front pillar 12, a center pillar 14, a cowl panel 16, a dash panel 17, and a roof constituting a floor. The panel 18 and the radiator support panel 20 constituting the engine room, the chapter panel 22, and the quarter panel 24 constituting the trunk and the black panel 26 are configured. In particular, the related conventional dash panel 17 of the present invention, as shown in FIG. 2, is vertically coupled to the cowl panel 16 and spot welded to the center floor panel 10 together with the reinforcement panel 28. Are combined. In addition, the lower panel 30 member constituting the lower portion of the dash panel 17, the vertical portion is coupled together to the welded portion of the reinforcing panel 28 and the dash panel 17, the horizontal portion of the dash panel 17 ) Is coupled to the lower portion by welding, the dash panel 17 is connected to the center floor panel 10, the structure is connected, in particular, the center floor panel 10 has a center floor horizontal member 33 is installed in a box-shaped cross-section A lateral reinforcement structure is achieved.

However, as described above, the structure in which the conventional dash panel is combined with the center floor panel is simply welded by overlapping the two panels, and thus cannot exhibit great rigidity in the event of side collision. As a separate horizontal member is welded on the surface, it increases the material cost and takes a lot of separate process and work time, and the welded parts are easily corroded and separated as time goes by, so the body stability in the event of side collision The results were not satisfactory with the protection of passengers and passengers. Therefore, in the present invention, without installing a separate horizontal member, by extending the dash panel to form a box section like the horizontal member, and joining the dash panel and the center floor before and after the reinforcement portion, the material reduction, as well as the rigidity increase effect Can be obtained at the same time, and is designed to simplify the assembly of vehicles and reduce the number of processes.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. The present invention has a structure in which the dash panel 17 and the center floor panel 10 are overlapped and bonded to each other so that the horizontal end of the dash panel 17 is folded. To make a cross-sectional groove 34 of the It is a joint structure of the dash panel and the center floor by welding the front and rear of the cross-sectional groove 34 of the center floor panel 10 to form a box (BOX) reinforcement structure. That is, as shown in FIG. 3, the box-shaped reinforcement structure is formed over the entire width of the center floor panel 10 so as to have the function of the conventional horizontal member 32, but without installing the separate horizontal member 32 by welding, As shown in FIG. 4, the area where the dash panel 17 is welded to the center floor panel 10 is formed. It is to be formed by bending the cross-sectional groove (34). therefore, The center floor panel 10 is welded together to form a welded portion 36 in the end face groove 34 of the The welding of the cross-sectional groove 34 and the center floor panel 10 constitutes a box-shaped reinforcement 38.

On the other hand, the reinforcement portion 38 is used as the center floor panel 10 and the dash panel 17 is a welded portion, Since the groove 34 of the cross section 34 is not to be formed only in the dash panel 17, that is, only the reinforcing portion 38 of the box-shaped cross section is formed at the welded portion of the horizontal portion of the center floor panel 10 and the dash panel 17, On the center floor panel (10) Reinforcing portions 78 are also formed in the same manner as the cross-sectional grooves 34 formed in the horizontal portion of the dash panel 17, and the center floor panel 10 and the dash panel 17 are the same. Symmetric The reinforcing portion 37 may be formed by forming and welding the end face groove 34 of the end face 34, and the effect of not attaching a separate horizontal member 32 as in the prior art is the same.

By bending the end of the dash panel or the center floor panel without welding the horizontal member as described above (or By forming the reinforcement part of the box-shaped cross section by forming the cross-sectional groove of the cross section and welding it back and forth, sufficient rigidity can be maintained on the side of the vehicle body, and at the same time, the effect of reducing the material and the number of working steps can be reduced. Of course, the cost reduction effect can also be obtained.
