Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) The present invention relates to the structure of an air flap provided on the outside of the front edge of a fender arch forming the outer contour of a wheel house of an automobile.

(Prior Art) Conventionally, an air flap has been provided on the outside of the front edge of a fender arch forming the outer contour of a wheel house of an automobile in order to increase the aerodynamic effect. Therefore, various proposals have been made regarding its structure. For example, an integrally molded tipping made of an elastic material that bulges outward in the vehicle width direction on the outside of the front edge of the rear fender arch and smoothly continues to the general surface of the fender is described in JP-A-58-136571. For example, a protector can be attached.

(Problem that the invention aims to solve) However, the above-mentioned chipping protector, or air flap, can be installed when the front part of the fender is wide and flat, but it can be installed on the front edge of the rear fender, such as in a four-door car. If the door edge is adjacent to the front part of the rear fender arch, the front part of the rear fender arch will be narrow in the longitudinal direction of the vehicle, making it difficult to install an air flap that is large enough to function as an air flap. The reality is that this is not the case. Therefore, even under the above-mentioned conditions, there still remains the technical problem of increasing the aerodynamic effect by providing an air flap.

Structure of the invention (means for solving the problems) In order to solve the above problems, the present invention is such that the air flap is provided separately on the outside of the fender arch and the outside of the door. The gist is that a fender-side air flap member that is continuous with the fender surface and extends outward from the vehicle body is provided on the outer side of the front edge of the fender arch that forms the outer contour of the wheel house of the automobile; A door-side air flap member is provided at a portion adjacent to the front edge of the fender arch and extends outward from the vehicle body and is continuous with the door surface, and when the door is closed, the outer surface of the fender-side air flap member and the door-side air flap member are substantially continuous. An air flap structure for an automobile is characterized in that it is configured to form a surface.

(Description of Embodiments) The present invention will be described in detail below based on embodiments shown in the drawings. FIG. 1 is a side view of an automobile showing the attachment site of an air flap according to the present invention. Figures 2 to 6 are diagrams for explaining the structure.
The figure is an enlarged view of the air flap in Figure 1, and Figure 3 is an enlarged view of the air flap in Figure 1.
The figure is a cross-sectional view taken along line A in Figure 2, Figure 4 is a cross-sectional view taken along line B, Figure 5 is a cross-sectional view taken along line C, and Figure 6 is an enlarged view of the area surrounded by the dotted circle in Figure 3. .

As shown in Figure 1, a rear fender arch 1 forms the outer contour of the rear wheel house of a four-door car.
A door-side air flap member 4 and a fender-side air flap member 5 are attached to the front outer side of the door 2 and the outer side of the door 2 adjacent to this portion, which are divided into a door side air flap member 4 and a fender side air flap member 5, which integrally form an air flap 3.
This air flap 3 is made up of members 4 and 5 as clearly shown in FIGS. ,
Each has a surface that is continuous with the fender and the general surface on the outside of the door, and is formed so as to constitute a mating surface 6 that faces each other at the edge of the door 2. The member 4 is attached to the door 2 by pasting double-sided adhesive tape 7 around the door-side surface of the member 4, and the member 5 is attached to the fender arch 1 around the fender-side surface in the same manner as described above. Furthermore, the side edge of the member 5 in the wheel direction is attached to the edge of the fender arch 1 as shown in FIG. 5, which is a sectional view taken along line C in FIG. It is tightened at several required points by bolts and nuts, and its lower side edge is tightened to the fender arch 1 at several required points by clips 8, as shown in FIG. 3, which is a sectional view taken along line A in FIG. On the other hand, the gap formed between the mating surfaces 6 of the members 4 and 5 is shown in FIG. 2 and FIG. 4 as a sectional view taken along line B in FIG. As shown in FIG. 6, a gap is provided at the joint between the edge of the door 2 and the edge of the member 4, and a soft rubber plate 9 is provided at this portion as a sealing member for sealing the gap between the mating surfaces 6. The ends are fitted and fixed. In FIG. 4, the reference numeral 10 indicates a tire.

Effects of the invention As described above, when the present invention is used, even when the front part of the rear fender arch is narrow in the longitudinal direction of the vehicle body, such as the rear fender arch of a four-door car, the width of the front part of the rear fender arch is narrow in the longitudinal direction of the vehicle body. The present invention greatly contributes to increasing the aerodynamic effect of automobiles because the air flap can be easily installed by dividing it into a fender-side air flap member and a door-side air flap member.
