A vehicle spoiler mounting structure according to an embodiment of the present invention is a vehicle spoiler mounting structure including a back door of a vehicle and a side spoiler attached to the back door, wherein the back door includes an outer panel on the outside of the vehicle and an inner side of the vehicle. The inner panel and the inner panel form a closed cross section, and the outer panel and the inner panel overlap at the end of the closed cross section in the vehicle width direction to form a predetermined flange. The vehicle spoiler mounting structure further includes a door-side clip for mounting a spoiler fixed to a region of the outer panel spanning the closed cross section and the flange, and a side spoiler. and a spoiler-side clip that is fixed to the door-side clip and fitted with the door-side clip.

In the above configuration, the door-side clip is fixed to a region of the outer panel that extends over the closed cross-section and the flange. Since this region is supported from the front side by the vertical wall region of the inner panel, it is less likely to bend than the outer panel. Therefore, the above-described door-side clip can stably support the side spoiler without falling off even if the side spoiler is subjected to stress when closing the back door or stress due to a pressure difference during driving. Further, with the above configuration, even in a portion of the outer panel where it is difficult to use bolts and nuts, the clip member with a simple configuration allows the side spoiler to be attached with high rigidity.

The above-mentioned back door may further include a window glass attached to the vehicle outer side of the outer panel, and the door-side clip may be fixed to the outer panel while being partially covered with the window glass.

According to the above configuration, even if the door-side clip tries to rise from the outer panel, the window glass interferes with the door-side clip, so that the door-side clip can be prevented from coming off.

The door-side clip may have a fitting portion that is provided so as to overlap the flange and fits with the spoiler-side clip, and a claw that penetrates the outer panel and is inserted into the closed cross section.

The fitting portion of the door-side clip is stressed inward in the vehicle width direction (hereinafter, referred to as the vehicle inner side) due to the air pressure difference that occurs around the side spoiler while the vehicle is running. With the above configuration, since the hook is provided on the inner side of the fitting portion, it is possible to withstand the stress toward the inner side of the vehicle.

The above-mentioned fitting portion projects from the flange toward the rear of the vehicle and has a barb around its tip side. It may have a grooved shape.

According to the above configuration, the door-side clip and the spoiler-side clip can be efficiently coupled with a simple configuration, and the side spoiler can be easily attached to the back panel.

The door-side clip described above may have a bent portion that is bent so as to contact the tip of the flange. According to this configuration, even if the door-side clip is subjected to a stress directed toward the vehicle interior, the bent portion is caught by the tip of the flange, thereby stabilizing the posture of the door-side clip and preventing it from coming off. In addition, the bent portion described above serves as a guideline for positioning when attaching the door-side clip to the outer panel, which leads to simplification of the attachment work.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in these examples are merely examples for facilitating understanding of the invention, and do not limit the invention unless otherwise specified.

FIG. 1 is a diagram showing an outline of a vehicle spoiler mounting structure (hereinafter referred to as mounting structure 100) according to an embodiment of the present invention. Hereinafter, in FIG. 1 and all other drawings of the present application, arrows F (Forward) and B (Backward) indicate vehicle front-rear directions, left and right arrows L (Leftward) and R (Rightward) respectively, and vertical directions of the vehicle. are exemplified by arrows U (Upward) and D (Downward), respectively.

The mounting structure 100 has a spoiler 104 on the upper part of the back door 102 of the vehicle for adjusting the surrounding airflow. Spoiler body 106 extends in the vehicle width direction above window glass 108 . The side spoilers 110 a and 110 b are portions supporting the spoiler body 106 at both ends of the back door 102 in the vehicle width direction, and extend downward from the ends of the spoiler body 106 . The side spoilers 110a and 110b are tapered slightly downward. In this embodiment, the side spoiler 110a is fixed to the back door 102 by a clip member, which will be described later, at the narrow lower end side.

FIG. 2 is a cross-sectional view of the mounting structure 100 of FIG. 1 taken along the line AA. The back door 102 has a structure in which an outer panel 112 on the outside of the vehicle and an inner panel 114 on the inside of the vehicle form a closed cross section S. The outer panel 112 and the inner panel 114 overlap each other at the end of the closed section S in the vehicle width direction to form a flange 116 extending outward in the vehicle width direction (hereinafter referred to as "vehicle outer side"). At the end of the flange 116, the outer panel 112 is bent toward the inner panel 114 and crimped. The window glass 108 is attached to the vehicle outer side of the outer panel 112 with an adhesive or the like.

The side spoiler 110a is attached to the outer panel 112 using a pair of clip members (door side clip 118, spoiler side clip 120). The door-side clip 118 is a spoiler-attaching clip member fixed to the outer panel 112 . The spoiler-side clip 120 is fixed to the side spoiler 110 a and fitted with the door-side clip 118 .

FIG. 3 is a perspective view showing the door-side clip 118 of FIG. 2 from each direction. FIG. 3(a) is an overall perspective view of the door-side clip 118. FIG. The door-side clip 118 has a rectangular base portion 122 , and has a configuration in which fitting portions 124 and claws 126 are provided at various locations on the base portion 122 . The fitting portion 124 is a projecting portion that fits with the spoiler-side clip 120 (see FIG. 2). The claw 126 is a portion for fixing the door-side clip 118 to the outer panel 112, is provided on the opposite side of the fitting portion 124 in the base portion 122, and is inserted into the outer panel 112 for use.

FIG. 3(b) is a view of the door-side clip 118 of FIG. 3(a) viewed from the claw 126 side. A double-faced tape 128 is attached to the claw 126 side of the base 122 and used to fix the door-side clip 118 together with the claw 126 . A bent portion 130 is provided at the end of the base portion 122 opposite to the claw 126 . As shown in FIG. 2, the bent portion 130 is formed by bending the edge of the base portion 122 and contacts the tip of the flange 116 . The bent portion 130 also serves as a guide for positioning when attaching the door-side clip 118 to the outer panel 112, leading to easier attachment work. FIG. 3(c) is an arrow B view of the door-side clip 118 in FIG. 3(a). The fitting portion 124 protrudes in a cylindrical shape from the base portion and has a barb 132 around the distal end side.

FIG. 4 is a perspective view showing the spoiler-side clip 120 of FIG. 2 from each direction. FIG. 4(a) is an overall perspective view of the spoiler-side clip 120. FIG. The spoiler-side clip 120 has a connecting portion 134 fitted to the side spoiler 110a (see FIG. 2) and a gripping portion 136 that grips the fitting portion 124 of the door-side clip 118. As shown in FIG.

FIG. 4B is a view of the spoiler-side clip 120 in FIG. The connecting portion 134 is shaped like a flange extending from the tip of the support, and is fitted inside the side spoiler 110a (see FIG. 2). The grasping portion 136 has a groove-shaped cross section and a claw 138 formed inside the tip, and is fitted from the tip side of the fitting portion 124 (see FIG. 3(c)) to grasp the barb 132 from the periphery. With these configurations, the door-side clip 118 and the spoiler-side clip 120 of FIG. 2 are combined efficiently while having a simple configuration, making it possible to easily attach the side spoiler 110a to the back door 102. As shown in FIG.

Refer to FIG. 2 again. In this embodiment, the above clip member is used to improve the fixing strength of the side spoiler 110a. Specifically, in this embodiment, the door-side clip 118 is fixed to the installation area E of the outer panel 112 that spans the closed cross section S and the flange 116 . Here, the inner panel 114 has a vertical wall region 140 extending toward the outer panel 112 at the boundary between the closed section S and the flange 116 . As a result, the installation area E is in a state where the front side is supported by the vertical wall area 140 .

The door-side clip 118 is fixed to the installation area E such that the claw 126 penetrates the outer panel 112 and is inserted into the closed cross section S, and the bent portion 130 is hooked to the tip of the flange 116 . Then, the fitting portion 124 protrudes from the flange 116 toward the rear of the vehicle.

As described above, the installation area E of the outer panel 112 is supported from the front side by the vertical wall area 140 of the inner panel 114, so that the outer panel 112 is less likely to bend. Therefore, even if the door-side clip 118 fixed to the installation area E is subjected to a stress toward the rear of the vehicle when the back door 102 is closed, the vertical wall area 140 presses the installation area E so that the installation area It does not float or fall off from E. That is, the door-side clip 118 can continue to stably support the side spoiler 110a.

With the above configuration, even when the side spoiler 110a is stressed by the air pressure difference during running, it can be suitably withstood. During running, the air pressure behind the back door 102 becomes smaller than the surroundings, generating a negative pressure. Due to the pressure difference with the surroundings at this time, the side spoiler 110a is stressed toward the vehicle interior side. Therefore, the side spoiler 110a is pulled in such a manner as to rotate toward the inside of the vehicle about the upper and lower shafts centering on the fitting portion 124 . However, since the door-side clip 118 is supported from the front side by the vertical wall region 140 and the claw 126 is inserted into the outer panel 112 on the vehicle-interior side of the fitting portion 124, the door-side clip 118 is resistant to the stress toward the vehicle-interior side. can be well tolerated. At this time, if the gripping portion 136 of the spoiler-side clip 120 grips the fitting portion 124 from the left and right sides in the vehicle width direction, the stress toward the vehicle interior can be absorbed more efficiently.

The bending portion 130 also exerts an effect on the above stress. Even if the door-side clip 118 is subjected to a stress toward the inside of the vehicle, the curved part 130 is hooked on the tip of the flange 116, so that the posture of the door-side clip 118 can be stabilized to prevent it from coming off.

The door-side clip 118 is fixed to the outer panel 112 with a portion of the vehicle interior, particularly the vicinity of the claw 126 , covered with the window glass 108 . According to this configuration, even if the door-side clip 118 tries to rise from the outer panel 112, the window glass 108 interferes with the door-side clip 118, so that the door-side clip 118 can be completely prevented from coming off.

As described above, this embodiment achieves attachment of the side spoiler 110a with a clip member having a simple configuration, and can be carried out even in a portion of the outer panel 112 where it is difficult to use bolts and nuts. It's becoming Since the bolt protrudes to the opposite side if the object to be used is not thick, it may be necessary to treat the protruding part so that it does not touch other structures. Compared to this, the clip member of the present embodiment is easy to use, and it is possible to reduce the number of man-hours for attachment and to reduce the weight of the member. In addition, since the side spoilers 110a and 110b can be easily attached, the degree of freedom in molding the side spoilers 110a and 110b is improved, which is advantageous in terms of design, such as narrowing the width of the lower end.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It is obvious that a person skilled in the art can conceive of various modifications or modifications within the scope described in the claims, and these also belong to the technical scope of the present invention. Understood.
