Description

[Detailed Description of the Invention] This invention relates to an automobile floor plate structure in which part of the shape of continuous beads is changed to facilitate bending and cutting according to the length of the floor plate.

When manufacturing several types of automobiles at the same time, some floorboards are formed using a single press mold, and the length of the floorboard is cut off depending on the type of car.

This floorboard has beads formed in parallel in the longitudinal direction of the vehicle body.

To explain this with the help of drawings, as shown in FIGS. 1 and 2, the floorboard 1 has beads 2 with a trapezoidal cross section that protrude downward in parallel from the front end (not shown) to the rear end 1a. The bottom is shaped by a press mold.

For vehicles with long floorboards that extend up to the rear end 1a,
There is no problem since the connecting flange formed by bending the rear end 1a can be directly connected to the skirt portion of the rear wall plate of the vehicle body, but for vehicle models with short floor plates, the floor plate must be cut before use.

If this floor section is made up to line A-A, the width of the connecting flange will be taken into account when cutting it, but the part where the bead 2 with a trapezoidal cross section is formed will have to be machined, so it will need to be bent. The cutting process becomes troublesome, and the shape of the bent connecting flange is likely to be irregular.

Therefore, in the past, without forming a bead at such a bent cut portion, this portion was formed into a flat plate portion using a press die and then processed.

If it is made into a flat plate part, bending and cutting will be easier and it will be suitable for car models with short floor plates, but if a floor plate shaped by the same press mold is used for a car model with a long floor plate, the rigidity or strength will decrease in the flat plate part. Moreover, vibration and noise were propagated, which was undesirable.

The present invention was devised in order to eliminate these drawbacks.The present invention has been devised in order to eliminate such drawbacks.The beads with a gentle arc-shaped cross section are connected in the vehicle width direction to the beads with a trapezoidal cross section that are arranged in parallel in the longitudinal direction of the vehicle body. They are formed in parallel on a line.

To explain this structure with reference to the embodiment shown in the drawings, the floor plate 1 is formed with beads 2 having a trapezoidal cross section that protrude downward in parallel from the front end (not shown) to the rear end 1a.

Then, a bead 3 having an arc-shaped cross section that gently bulges downward as shown in FIG. 3 is formed at the section along the line B--B where the floor plate is bent and cut according to the short car model.

This will facilitate processing when bending and cutting along the line B-B.

That is, as shown in FIG.
are formed in an orderly manner, and the rear wall plate 4 of the vehicle body is formed as shown in FIG.
It can be reliably connected to the skirt portion 4a of.

As mentioned above, the present invention manufactures the floor plate using one press die, and for car models with short floor plates, the floor plate is bent and cut at the bead portion with a gentle arc-shaped cross section, making it easy to form the connecting flange. .

Furthermore, when used in a car model with a long floor plate, since a bead with a gently arcuate cross section remains, the rigidity or strength does not decrease in this part, and problems with vibration and noise do not occur.

In the drawings for explanation, the bead is shown as concave and raised downward with respect to the floorboard, but on the other hand, the bead may be curved and raised upward with respect to the floorboard, and the same effect can be obtained.
