Description

[Detailed description of the invention] [Industrial application field] This invention relates to a rocker panel structure in which chipping-resistant coating is applied to the outer surface of a rocker panel, etc. at the bottom of an automobile body, for example, to prevent damage caused by the chipping phenomenon. be.

[Conventional technology]

BACKGROUND ART Conventionally, for example, when a car is running, gravel or rock salt on the road surface may be thrown up and hit the car body, and this phenomenon is generally referred to as a chipping phenomenon. In order to prevent damage to the car body due to this chipping phenomenon, a chipping-resistant coating is applied to the outer surfaces of the rocker panels formed on the lower part of the car body, and the thickness and elasticity of this coating film prevents scratches from reaching the base material. It's becoming like that. In addition, this chipping-resistant coating is sometimes applied to the front fenders and quarter panels arranged in the longitudinal direction of the vehicle, and is often applied with black coating (generally referred to as blackout treatment). ), which also serves to enhance the design effect (appearance).

A rocker panel structure having such a structure is, for example, a rocker panel 1 having a closed cross section formed by an outer panel 2 and an inner panel 3, as shown in FIG. The outer panel 2 of the rocker panel 1 includes a bulging wall 5 that protrudes outward in the vehicle width direction from an extension line 41 of the vehicle outermost lower end hemming portion 40 of the door panel 4, and a bulging wall 5 projecting outward in the vehicle width direction from the outer end 5a of the bulging wall 5. It is formed by an inclined wall 6 that extends in an inclined manner toward the inside of the vehicle. When applying anti-chip coating to the rock panel 1 (outer panel 2) constructed in this way, masking is performed with tape or the like to cleanly finish the border with the general painted surface of the vehicle body, and this masking surface 7' is applied to the rock panel 1 (outer panel 2). Near the upper end of the inclined wall 6 forming the outer panel 2 (i.e., the outer panel 2
(the part that protrudes most outward in the vehicle width direction). and a region below the masking surface 7' of the inclined wall 6 forming the outer panel 2.
A' is coated with chipping-resistant coating P.

[Problem that the invention attempts to solve]

However, in the case of the rocker panel structure shown in FIG. 4, as described above, the masking surface 7' is formed near the upper end of 6 forming the outer panel 2 (that is, the part of the outer panel 2 that protrudes most outward in the vehicle width direction). The lower part from this masking surface 7'
Since only A' is coated with chipping-resistant coating P, the chipping-resistant coating P is applied to the masking surface 7' near the upper end of the inclined wall 6, which is the part of the outer panel 2 where scratches are most visible due to the chipping phenomenon.
In addition, the bulging wall 5 of the outer panel 2, which should be painted black (blackout treatment) for the sake of design, cannot be painted, and the design effect (appearance) is also deteriorated.

Therefore, the purpose of this invention is to reliably perform chipping-resistant coating and prevent scratches due to the chipping phenomenon, that is, to improve the chipping-resistant performance and to significantly improve the design effect (appearance).

[Means for solving problems]

Therefore, this invention solves the above-mentioned problem by forming a bulge in the bulge wall that forms the outer panel of the rocker panel and protrudes outward in the vehicle width direction.
This problem is solved by using the protruding surface of the bulge as a masking surface during chipping prevention.

More specifically, referring to the reference numerals shown in FIG. 1, the rocker panel 1 is formed by an outer panel 2 and an inner panel 3 forming a closed cross section, and the outer panel 2 of the rocker panel 1 is the outermost part of the door panel 4 of the vehicle. Extension line 41 of the outer lower end hemming part 40
A bulging wall 5 that projects further outward in the vehicle width direction
In the rocker panel 1 formed of the slanted wall 6 extending from the outer end 5a of the swollen wall 5 toward the vehicle bottom and inward of the vehicle, the lower end hemming of the door panel 4 is attached to the swollen wall 5 of the outer panel 2. A bulge 50 is formed on substantially the same plane as the extension line 41 of the door panel 4 and protrudes toward the lower end hemming part 40 of the door panel 4, and the extension line 41 of the lower end hemming part 40 of the door panel 4 and the bulge 50 are formed. The protruding surface portion 51 extending substantially on the same plane serves as the masking surface 7 during chipping-resistant coating, and the bulging wall 5 protrudes outward in the vehicle width direction from near the lower corner 51a of the protruding surface portion 51. The area between the bulging wall 5 and the inclined wall 6 is a chipping-resistant coating area.

[Effect]

According to the above-mentioned means, chipping-resistant coating can be reliably applied between the bulging wall 5 forming the outer panel and the sloping wall 6 connected to this bulging wall 5, including the upper end of the sloping wall 6 where chipping-resistant coating is most necessary. P, the chipping resistance is improved, and
The design effect is also improved.

〔Example〕

Embodiments of this invention will be described below based on the accompanying drawings. The drawings from FIG. 1 to FIG. 3 show an embodiment of this invention, and as can be seen from FIG.
etc. are coated with chipping-resistant coating P. The rocker panel 1 and the chipping-resistant coating P will be described in detail. As can be seen from FIG. 1, the rocker panel 1 is formed by an outer panel 2 and an inner panel 3 forming a closed cross section. The outer panel 2 of the rocker panel 1 includes a bulging wall 5 that protrudes outward in the vehicle width direction from an extension line 41 of the vehicle outermost lower end hemming portion 40 of the door panel 4, and a bulging wall 5 projecting outward in the vehicle width direction from the outer end 5a of the bulging wall 5. It is formed by an inclined wall 6 extending toward the inside of the vehicle. The bulging wall 5 of the outer panel 2 that protrudes outward in the vehicle width direction from the extension line 41 of the vehicle outermost lower end hemming part 40 of the door panel 4 has an extension line 41 of the lower end hemming part 40 of the door panel 4. A bulge 50 is formed on the same plane and protrudes toward the lower hemming portion 40 of the door panel 4. This bulging portion 50 includes a protruding surface portion 51 extending substantially on the same plane as the extension line 41 of the lower end hemming portion 40 of the door panel 4, and
A horizontal surface 52 is formed which is bent toward the inside of the vehicle from the outer panel 1 and continues to the vertical surface 5b of the outer panel 2. and a lower end hemming portion 4 of the door panel 4.
The bulge 5 is substantially on the same plane as the extension line 41 of 0.
The protruding surface portion 51 of No. 0 is used as the masking surface 7 during chipping-resistant coating. Therefore, a bulging wall 5 protrudes outward in the vehicle width direction from below the masking surface 7, that is, from near the lower corner 51a of the protruding surface portion 51, and the inclined wall 6 continuous with the bulging wall 5. The area A between the two is the chipping-resistant coating area, and the chipping-resistant coating P is applied to this area A. Thus, the masking surface 7 of the protruding surface portion 5
By masking the surface with tape or the like and applying chipping-resistant coating P, the area near the lower corner 51a of the protruding surface 51 (in this embodiment, the corner 51
Since the area A between the bulging wall 5 and the inclined wall 6 connected to the bulging wall 5 from slightly above a) is coated with the chipping-resistant coating P, the area A where the chipping-resistant coating P is most needed, the so-called most Highly visible locations, namely the outer end 5a of the bulging wall 5 and the inclined wall 6
The chipping-resistant coating P can be reliably applied to the vicinity of the upper end, thereby preventing scratches due to the chipping phenomenon and improving the so-called chipping-resistant performance. Furthermore, since the bulging wall 5 of the outer panel 2 which is to be painted black or the like for a design effect (blackout treatment) is also painted at the same time, the design effect (appearance) of this part is also improved.

In the above explanation, the structure of only the rocker panel 1 at the lower part of the vehicle body has been explained, but this invention is not limited to this embodiment. If the shape is the same, it becomes possible to apply chipping-resistant coating P to the same area as the rocker panel 1. As an example, the case of the quarter panel Q will be explained in a second manner.The bulging wall 5Q and the inclined wall 6Q of the quarter panel Q are made to have substantially the same external outline shape that continues to the rocker panel 1, and the corner portion of the bulging wall 5Q toward the inside of the vehicle By making the quarter panel outer panel Q bent upward from 5C to the vehicle outermost side of the door panel 4, the outside of the quarter panel corresponding to the same position as the masking surface 7 of the rocker panel 1 is formed. The chipping-resistant coating P can be applied to this lower part (area A) using the plate Q as a masking surface 7Q. By painting the rocker panel 1, quarter panel Q, front fender F, etc. black, for example, the chipping resistance is improved, and the design effect (appearance) is further improved.

[Effect of idea]

As mentioned above, this idea is based on the rock panel, front fender, and quarter panel.
The chipping-resistant coating can be reliably applied to the areas where the chipping-resistant coating is most needed (the most visible), and scratches caused by chipping can be prevented, that is, the chipping-resistant performance is greatly improved. Furthermore, it is also possible to simultaneously paint areas where it is desired to be painted black (so-called blackout treatment) for a design effect, and the design effect (appearance) of this area is also greatly improved. Furthermore, the front fender and quarter panel connected to the rocker panel can also be painted at the same time, improving the chipping resistance of these parts and improving the overall design effect (appearance) of the vehicle when viewed from the side.
