Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the structure of the front part of an automobile rocker, particularly to the structure of the joint between the front part of the rocker and the dash.

[Conventional technology]

In an automobile as shown in Fig. 1, the front end of the rocker 1 formed along the side edge of the floor (A
part) is joined to the darts part that partitions the front part of the passenger compartment.

FIGS. 6 to 8 show the conventional structure of the joint, in which the locker 1 forms a closed cross section with the locker inner panel 11 and the locker outer panel 12, and is closed at the front end. On the other hand, the darts section 2 that partitions the front part of the vehicle interior is a closed structure that extends in the vehicle width direction and consists of a dash panel 3 that partitions the front part of the vehicle interior, and a steering gear box member 4 that is disposed along the front of the lower part and supports a steering gear box, etc. The ends of the dash panel 3 and the steering gear box member 4 form a rocker inner panel 11.
is welded to.

Incidentally, since vibrations from the engine support member are inputted to the dash 2, the joint between the dash 2 and the rocker 1 needs to have sufficient rigidity. If the thickness of each panel constituting the rocker 1 and the dash section 2 is increased in order to increase the rigidity, there is a problem that the weight of the vehicle increases. In addition, by increasing the thickness of the plate, the rigidity of the locker 1 itself and the darts section 2 itself can be improved, but with a joint structure that only connects the end of the darts section to the locker inner panel, the strength and rigidity of the joint will be reduced. There are limits.

[Purpose of invention]

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a rocker front structure that can strengthen the rigidity of the joint between the rocker and the dash without increasing the plate thickness of the rocker and dash.

[Structure of the idea]

The structure of the present invention to achieve the above objectives is as follows:
The connecting part between the front end of the locker and the side end of the dash is formed into a continuous closed cross section, and within this closed cross section, two reinforcements are installed, the front end being connected to the steering gear box member of the dash and the rear end being connected to the lock. The invention is characterized in that the reinforcing panels are combined into a closed cross-section structure.

〔Example〕

Hereinafter, details of the present invention will be explained with reference to embodiments shown in FIGS. 2 to 5.

The rocker 1 consists of an inner panel 11 and an outer panel 12, which are welded at the upper and lower flanges to form a closed cross section extending in the front-rear direction. on the other hand,
The dash portion 2 is a dash panel 3 having an inclined surface on a steering gear box member 4 having an L-shaped cross section.
The lower ends of the rocker 1 are welded at the upper and lower positions, and as shown in FIGS. 2 and 4, both form a closed cross-sectional structure substantially perpendicular to the rocker 1.

As shown in FIG. 4, the front end of the rocker outer panel 12 is welded to the side end of the vertical portion of the steering gear box member 4. As shown in FIG. Lotsuka inner panel 1
The tip of the locker 1 is located rearward from the locker outer panel 12 and faces the end of the dash panel 3, and the front end of the locker 1 and both left and right ends of the dash section 2 are formed into a continuous closed cross section.

As shown in FIG. 4, the lock inner panel 11
The rear end of the first reinforcing panel 5a arranged in the continuous closed section is welded to the outer surface of the opposing portion of the dash panel 3. This first reinforcing panel 5a is bent and extends diagonally forward within the closed cross section of the dash portion 2,
Its tip faces the vertical portion of the steering gear box member 4.

On the other hand, the front part of a second reinforcing panel 5b is welded to the vertical part of the steering gear box member 4, and the panel 5b is bent almost parallel to the first reinforcing panel 5a to move backward inside the locker 1. It extends, and its rear end reaches the rear end of the first reinforcing panel 5a. and first and second reinforcing panels 5a,
5b is welded at its upper and lower flange portions, and crosses within the joint between the rocker 1 and the dash portion 2 to form a closed cross-sectional structure extending from the rocker 1 to the steering gear box member 4.

That is, as shown in FIG. 3, in the front part of the locker 1, the first and second reinforcing panels 5a,
A rocker outer panel 12 is attached to the upper and lower flanges of the closed section structure formed by b on the second reinforcing panel 5b side.
The upper and lower flanges of the steering gear box member 4 are welded together, and the closed cross-sectional structure is bent as a whole and extends into the dash part 2 along the vertical part of the steering gear box member 4, and has an L-shaped cross section as shown in FIG. The reinforcing panel 5b of No. 2 is welded to the steering gear box member 4, which also has an L-shaped cross section.

[Effect]

In the above configuration, the connecting part between the front end of the locker 1 and both left and right ends of the dash part 2 has a continuous closed cross-sectional structure, one end of the first reinforcing panel 5a is joined to the lock inner panel 11, and the other end is connected to the dash part 2.
The second reinforcing panel 5b has one end joined to the rocker outer panel 12, and the other end enters the cross section of the dash portion 2 and is joined to the steering gear box member 4. Since they are joined, the rigidity of the joint is strengthened. Furthermore, by joining both reinforcing panels to each other to form a closed cross-section structure, the rigidity can be improved more effectively. Further, in this structure, the rigidity can be increased simply by increasing the thickness of the reinforcing panels 5a and 5b. Furthermore, both reinforcing panels 5a, 5b
Since the closed cross-section structure constituted by the structure is disposed diagonally across the rocker 1 and the dash section 2, the rigidity of the connecting section can be increased in all directions. Furthermore, the rocker outer panel 12 is joined to the reinforcing panel structures 5a and 5b at the same time as the steering gear box member 4, and the dash panel 3 is connected to the rocker inner panel 11 and the rocker outer panel 12 through the reinforcing panel structures 5a and 5b.
and the steering gear box member 4, and the rocker inner panel 11 is joined to the dash panel 3, the steering gear box member 4, and the rocker outer panel 12 via reinforcing panel structures 5a and 5b, and each panel is joined in a complex manner. Therefore, the bonding strength is extremely high.
