Description

  The present invention relates to a structure of a vehicle body side portion of a vehicle.

Conventionally, as shown in FIGS. 4 to 6, a tire (not shown) is joined to a vehicle body side portion of a vehicle by joining a side body outer panel 51 of an outer panel and a wheel house outer panel 52 of an inner panel. The wheel house 53 is formed to cover a part of the upper region, the front and rear region, and the outer region of the outer periphery of the outer periphery. For this reason, flanges 51a and 52a having a predetermined width bent toward the vehicle interior side are formed at end portions of the side body outer panel 51 and the wheel house outer panel 52, and the flanges 51a and 52a are overlapped. By joining in a state, the side body outer panel 51 and the wheel house outer panel 52 are configured to have a lower space portion 54 (see, for example, Patent Documents 1 and 2).
Further, on the outer surface of the side body outer panel 51, the exterior design is improved as a decorative part, and the rear side of the side body outer panel 51 is protected from the rear side for functional reasons such as protecting the end portion of the vehicle body from muddy water and rain. A fender splash guard 55 is attached using a plurality of clips 56. The rear fender splash guard 55 is formed in the same shape as the side body outer panel 51 located in the wheel house 53, and is disposed so as to cover the vehicle outer side of the side body outer panel 51 and the wheel house outer panel 52. Therefore, on the outer surface of the side body outer panel 51, a plurality of mounting holes 57 for inserting the clips 56 are arranged in an arc shape with a certain interval.

However, in the conventional vehicle body side structure described above, the mounting hole 57 of the clip 56 is surrounded by the side body outer panel 51 and the wheel house outer panel 52 as shown in FIGS. Since it becomes a through-hole that leads to the space 54 (vehicle interior), when water enters the lower space 54 from the mounting hole 57, the water that has entered accumulates near the bottom of the lower space 54, and rust is generated in that portion. There was a risk. Therefore, in many vehicles, a clip (water stop clip) having a sealing function is used as a measure for preventing water from entering the lower space 54. In this case, the weight or There was a problem that the cost increased, and it was not an effective measure.
Moreover, in the structure of the conventional vehicle body side part, as shown in FIG. 4, since the joint ends 58 of the flanges 51a and 52a are provided on the center C side (for example, a low position) of the radius of curvature of the wheel house 53, There is a problem that water is easily applied. Therefore, in the conventional structure, in order to prevent the occurrence of rust due to water intrusion into the lower space portion 54, a water stop sealer 59 is provided at the joint end 58 of the flanges 51a and 52a as shown in FIG. Some are applied. However, when applying the water sealer 59 to the joint end 58 of the flanges 51a and 52a, it is difficult to work with the tip of the sealer nozzle 60 aligned with the joint end 58, which is a cross-sectional portion between the panels, the flanges 51a and 52a. There was a problem. On the other hand, when the worker applies the water stop sealer 59 manually, there is a concern that a defective application of the water stop sealer 59 may occur.

Furthermore, in the conventional structure of the vehicle body side portion, as shown in FIGS. 5 and 8, the lower space portion 54 formed by the side body outer panel 51 and the wheel house outer panel 52 extends to the joint end 58 of the lower flanges 51a and 52a. Although extending, the lower space 54 is not an essential structure in that the rear fender splash guard 55 is attached. Further, since the lower end flanges 51a and 52a are bent almost horizontally toward the inside in the vehicle width direction, the welding point W is difficult to see from the outside of the vehicle, and a welding gun for welding the flanges 51a and 52a. The welding work by 61 has the trouble that it takes time.
Moreover, the wheel house outer panel 52 is provided with a protruding portion 52b formed by protruding a part of the wheel house outer panel 52 in the vehicle width direction so as to secure a space for attaching the clip 56. For this reason, in the conventional structure, as shown in FIG. 8, the welding gun 61 and the protruding portion 52 b for the clip 56 overlap each other when viewed in the vehicle front-rear direction, and thus it is necessary to shift the positions of both. In connection with this, the attachment location of the clip 56 and the welding location are subject to arrangement restrictions, and there is a problem that the degree of freedom in design is reduced.

  The present invention has been made in view of such a situation, and an object thereof is to install water in the lower space surrounded by the outer panel and the inner panel without using a water stop clip. It is possible to easily and surely apply the waterproof sealer and the outer and inner panels, and to weld the required number of parts necessary for performance, and to connect the outer panel joint flange.

A joint surface with the inner panel is formed by extending toward the center side of the radius, and an inner step formed toward the outer panel near the center side end of the radius of curvature of the wheel house of the inner panel. And a joint surface with the outer panel is formed by extending from the inner step toward the center of the radius of curvature of the wheel house.

As described above, the structure of the vehicle body side portion according to the present invention has a wheel house formed by joining the outer panel and the inner panel, and a fender splash guard is attached to the outer surface of the outer panel. Since the outer panel located closer to the center of the radius of curvature of the wheel house than the joint surface between the panel and the inner panel is provided with a fixing hole for fixing the fender splash guard, a special hole is provided. Without using a water stop clip, water can surely be prevented from entering the lower space surrounded by the outer panel and the inner panel and the vehicle interior from the mounting hole of the fixture, and the occurrence of rust in the lower space is prevented. While being able to prevent, weight and cost can be reduced.
Moreover, the joint surface between the outer panel and the inner panel is substantially the same in cross-sectional shape as the portion provided with the mounting hole of the fixture, and is set on the side opposite to the center side of the radius of curvature of the wheel house, It becomes easy to check the welding point from the outside of the vehicle, the welding work between the outer panel and the inner panel can be done easily and reliably, and it is necessary for the performance necessary place without being limited to the installation place of the mounting hole While it is possible to weld as many as possible, the joining flange of the inner panel can be omitted, and the joining strength and weight of the panel can be improved.

  Further, in the present invention, the center side end portion of the radius of curvature of the wheel house of the inner panel extends in a direction away from the outer panel, so that the water sealing sealer can be applied easily and reliably. The assembly performance of the vehicle body can be improved. In addition, the center side edge of the inner panel can be set above the vehicle on the opposite side of the center of the radius of curvature of the wheel house from the installation location of the mounting hole. Weight reduction of panels and the like can be realized.

  Furthermore, in the present invention, the center side end portion of the inner panel is disposed so as to form an acute angle with the panel surface of the outer panel provided with the mounting hole. It becomes possible to easily position and fix at the application location, and it is possible to prevent the application failure of the water sealer.

  Further, in the present invention, an outer step portion formed toward the inner panel is provided near the center side end portion of the curvature radius of the wheel house of the outer panel, and the curvature of the wheel house is formed from the outer step portion. A joint surface with the inner panel is formed by extending toward the center side of the radius, and an inner step formed toward the outer panel near the center side end of the radius of curvature of the wheel house of the inner panel. Since the joint surface with the outer panel is formed by extending toward the center side of the radius of curvature of the wheel house from the inner stepped portion, the vehicle body rigidity around the mounting portion of the fender splash guard is increased. The fender splash guard can be stably attached without being detached from the side of the vehicle body.

Has been. And between the 1st inner side step part 31 and the 2nd inner side step part 32, it formed in the curved shape which protrudes toward the vehicle interior side (arrow R direction) on the opposite side to these step parts 31 and 32. A third inner step 34 is provided.

Further, as shown in FIG. 1, the outer side surface of the side body outer panel 2 is improved in appearance design as a decorative part, and the center side end portion of the side body outer panel 2 from the muddy water and rain that the tire jumps up is provided. A resin-made rear fender splash guard 6 having a function of protecting or the like is attached using a plurality of clips 7 which are fixing tools. Such a rear fender splash guard 6 is formed in the same circular arc shape as the side body outer panel 2 located in the wheel house 4, and is arranged so as to cover the vehicle outer side of the side body outer panel 2.
Therefore, the clip 7 is inserted into the outer surface of the side body outer panel 2 located on the center side (lower side in FIGS. 1 and 2) of the radius of curvature of the wheel house 4 with respect to the outer joint surface 23 and the inner joint surface 33. A plurality of mounting holes 8 are arranged in a circular arc shape with a certain interval. Accordingly, the side body outer panel 2 extends substantially linearly from the outer joint surface 23 toward the center side of the radius of curvature of the wheel house 4 (downward in FIG. 1) in order to dispose the mounting hole 8. An extending portion 25 is provided. Therefore, these mounting holes 8 are not holes that communicate with the inside of the lower space portion 5 formed by the side body outer panel 2 and the wheel house outer panel 3, and prevent water from entering the vehicle interior from the mounting holes 8. There is no longer any need to adopt preventive measures. Further, the rear fender splash guard 6 is provided with a protruding portion that protrudes toward the vehicle interior side (in the direction of arrow R) as in the prior art, so that it is not necessary to secure a space for attaching the clip 7.

As shown in FIG. 1, the rear fender splash guard 6 of the present embodiment is formed in a substantially L-shaped cross section so that the outer surface 6 a is continuous with the general surface 2 a of the side body outer panel 2. The size of the panel 2 is set so as to cover from the first outer step portion 21 to the end portion of the extending portion 25. Further, on the back side of the rear fender splash guard 6 and on the center side of the radius of curvature of the wheel house 4 (downward in FIG. 1), there is a space 61a for accommodating the head 7a of the clip 7, and a vertical wall 61b. A plurality of clip boxes 61 each having a clip hole 62 for holding a part of the shaft portion 7 b of the clip 7 are provided corresponding to the mounting holes 8 of the side body outer panel 2.
The outer diameter of the tip end of the shaft portion 7b of the clip 7 is formed to be large enough to be inserted into the mounting hole 8, and is inserted into the mounting hole 8 at an intermediate portion of the shaft portion 7b of the clip 7. A holding piece 71 that is sandwiched between the extending portion 25 and the vertical wall 61 b and increases the holding force of the clip 7 is provided.

On the other hand, in the wheel house outer panel 3 of the present embodiment, the side body outer panel is located at the end portion (lower end portion in FIGS. 1 and 2) located on the center side of the radius of curvature of the wheel house 4 with respect to the inner joint surface 33. 2 is provided with a bent piece 35 extending toward the vehicle interior side (in the direction of arrow R) away from the vehicle. The bent piece portion 35 is formed by bending and standing the center side end portion so as to form an acute angle θ with the panel surface of the extending portion 25 of the side body outer panel 2 provided with the attachment holes 8. It is arranged with an inclination.
As shown in FIG. 2, the bent piece portion 35 can be easily positioned at the application portion 11 of the water stop sealer 10 at the tip 9 a of the sealer nozzle 9, so that the water stop sealer 10 can be applied quickly. And it is performed reliably and the application | coating defect of the water stop sealer 10 to the application location 11 by the position shift of the sealer nozzle 9 does not arise.

Thus, in the structure of the vehicle body side portion 1 according to the embodiment of the present invention, the curvature radius of the wheel house 4 is larger than the outer joint surface 23 and the inner joint surface 33 between the side body outer panel 2 and the wheel house outer panel 3. A mounting hole 8 for a clip 7 for fixing the rear fender splash guard 6 is provided in the extending portion 25 of the side body outer panel 2 extended to the center C side (lower side in the drawing). As shown in FIG. 5, unlike the conventional structure, the mounting hole 8 is not a hole that communicates with the lower space portion 5, and water applied to the rear fender splash guard 6 or the like passes through the lower space portion 5 from the mounting hole 8 to the vehicle interior. Can be surely prevented from entering. In addition, the bent piece 35 at the center side end of the wheel house outer panel 3 is provided above the vehicle on the opposite side of the center of the radius of curvature of the wheel house 4 from the place where the mounting hole 8 is installed. Since 10 application locations 11 are arranged at a location higher than the conventional structure by a distance L, it is difficult to splash water and the water stop performance of the water stop sealer 10 can be maintained over a long period of time. The wheel house outer panel 3 can be reduced in weight corresponding to the dimension of the distance L.
Further, in the structure of the vehicle body side portion 1 according to the present invention, a space for attaching the clip 7 which is necessary in the conventional structure becomes unnecessary, and there is no need to provide a protruding portion on the wheel house outer panel 3. The side body outer panel 2 and the wheel house outer panel 3 can be welded to each other at the outer joint surface 23 and the inner joint surface 33 without being restricted by the location, and the joint strength between the panels 2 and 3 can be increased. .
Further, in the structure of the vehicle body side portion 1 of the present invention, outer step portions 21, 22, 24 and inner step portions 31, 32.34 are provided, and the side body outer panel 2 and the wheel house outer panel 3 are provided by these step portions. Are configured to approach each other in the vehicle width direction, so that the rigidity around the mounting portion of the rear fender splash guard 6 can be improved as compared with the conventional structure, and the vehicle width direction of the rear fender splash guard 6 can be improved. The amount of outward protrusion can be reduced, and a good appearance of the vehicle body side portion 1 can be maintained.

  While the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made based on the technical idea of the present invention.

  For example, in the above-described embodiment, three outer step portions 21, 22, 24 and inner step portions 31, 32, 34 are provided near the ends of the side body outer panel 2 and the wheel house outer panel 3. However, one or four or more steps may be provided depending on the applicable vehicle type. Further, the structure of the present invention can be applied not only to the vehicle body side portion 1 at the rear of the vehicle but also to the vehicle body side portion at the front of the vehicle.
