本考案は自動車のフロアサイドフレーム構造に
関するものである。[Detailed Description of the Invention] The present invention relates to a floor side frame structure of an automobile.
自動車のフロア下面両側部にはサイドフレーム
が前後方向に接合固定されるのが普通である（例
えば実開昭56−113079号公報参照）。 It is common for side frames to be joined and fixed to both sides of the lower surface of an automobile floor in the longitudinal direction (see, for example, Japanese Utility Model Publication No. 113079/1983).

不足すると言う問題を生じている。 However, as shown in FIG. 1, the rear floor 1 has a step of a predetermined height formed between the rear seat installation part 1a and the floor pan 1b behind it, and the side frame 2 is joined and fixed to the lower surface of the step. The front end portion A of the floor pan 1b is bent downward, and since this bent portion is likely to bend under a load from the rear, a doubler 3 is joined and fixed to the bent portion of the side frame 2 for reinforcement. There is. Furthermore, since there is a rear wheel apron 4 on both sides near the above-mentioned part A, the side frame 2 in that part is formed into an L-shaped cross section as shown in FIG. 21 is bonded and fixed to the rear wheel apron 4, the flange portion 22 at the upper end of the elevation of the side frame 2 is bonded and fixed to the rear floor 1, and the side end flange portion 11 is bonded and fixed to the rear wheel apron 4. 4 and the side frame 2 having an L-shaped cross section generally form a closed cross section, but since the cross member 5 is installed exactly at the bending part of the side frame 2, the cross member 5 Both ends of are the first
As shown in Figures B and C, the end of the cross member 5 covers the lower surface of the upper end flange 22 that abuts against the vertical surface of the side frame 2, and the covered area is between the flange 22 and the rear floor 1. Spot welding with the lower surface of the floor pan 1b becomes impossible, resulting in a problem that the bonding strength between the side frame 2 and the floor pan 1b is insufficient.
本考案は、新たな部品の追加は一切なしに極め

着した構成としたものである。 That is, in the present invention, the doubler 3, which is joined and fixed near the bending part of the front end of the floor pan of the side frame 2, is connected to the flange part 3 at the top and bottom as shown in FIGS.
1 and 32 are bent to have a substantially U-shaped cross section, and the doubler 3 is joined to the vertical surface of the frame 2 by matching the portion where the ends of the cross members 5 of the bent portions of the side frames 2 abut against each other. The lower flange part 32 of the doubler 3 is joined to the bottom surface of the side frame 2, and both of the joined parts are fixed by spot welding W 1 and W 2 in the opposite direction to the flange part 22 at the upper end of the vertical surface of the side frame 2. The upper flange part 31 of the doubler 3, which protrudes from the top and is flush with the flange part 22, is fixed to the lower surface of the floor pan 1b by spot welding W3 .

得るものである。 According to the present invention configured as described above, a doubler is used to prevent bending of the bent portion of the side frame against longitudinal loads, and the portion of the side frame and floor pan that cannot be directly spot welded is fixed to the side frame. This makes it possible to connect the side frame and floor pan seamlessly without adding any new parts, thereby significantly improving the strength of the connection between the side frame and floor pan. The number of parts is small and the workability is extremely good, which together with the fact that it can bring about great practical effects.
