Description

  The present invention relates to a vehicle wheel house structure in which an arch portion at the lower end of a vehicle body outer plate and an outer end portion of a wheel house outer panel are joined together, particularly from an arch portion of a vehicle body outer plate and an outer end portion of a wheel house outer panel. The present invention relates to a structure of a wheel house part of an automobile that bends inward of the vehicle.

  In general, the rear wheel house portion of the automobile shown in FIG. 5 includes an arch portion 10 provided at the lower end of the quarter panel 1 that constitutes the outer plate of the vehicle body, and an arch-shaped wheel house outer panel disposed inside the quarter panel 1. Two outer end portions 20 are coupled to each other. These connecting portions form flanges that are bent at substantially right angles from the arch portion 10 of the quarter panel 1 and the outer end portion 20 of the wheel house outer panel 2 to the inside of the vehicle, respectively, on the arch portion flange of the quarter panel 1. The flanges on the outer end portion of the wheel house outer panel 2 are overlapped and welded to each other. In this case, since both flanges require a welding allowance, the flange lengths of both flanges are long and the amount of protrusion to the inside of the vehicle is large.

  In recent years, there is a tendency to dispose the wheels as far as possible in the vehicle width direction from the viewpoint of making the gap between the wheel and the wheel house as small as possible to improve the appearance of the vehicle body and widening the width of the passenger compartment. . In this case, if the protruding amount of the flange of the wheel house is large, the flange and the wheel may interfere with each other when the vehicle body and the wheel move relatively up and down. In the wagon car etc. where the vehicle height changes greatly between the time and the time of boarding, it is necessary to downsize the flange of the wheel house.

Therefore, conventionally, in order to reduce the flange of the wheel house portion, the flanges 15 and 25 are overlapped without welding the flange 15 of the quarter panel 1 and the flange 25 of the wheel house outer panel 2 as shown in FIG. In this state, the inner surface of the arch portion 10 of the quarter panel 1 and the outer surface of the outer end portion 20 of the wheel house outer panel 2 are bonded with an adhesive 3 (see, for example, Patent Document 1). 4 in the figure is a sealer that seals between the flanges 15 and 25.

  However, in the structure in which the lower end portion of the quarter panel 1 and the outer end portion of the wheel house outer panel 2 are bonded and bonded together with the adhesive 3, the quarter panel 1 and the wheel house outer panel 2 are arranged so that the flanges 15 and 25 thereof are moved up and down. Because of the overlap, the wheel house outer panel 2 can be easily aligned in the vertical direction with respect to the quarter panel 1, but it is difficult to align in the vehicle width direction, and the lower end of the quarter panel 1 depends on the coating thickness of the adhesive 3. The clearance between the outer end portion of the wheel house outer panel 2 and the vehicle width direction is likely to change, and the amount of protrusion of the flange 25 of the wheel house outer panel 2 toward the vehicle interior varies. If the clearance is large, the amount of protrusion of the flange 25 increases. Become.

  Further, in the conventional adhesive structure, when the quarter panel 1 is damaged due to a light contact accident of the vehicle and a part of the adhesive joint part is peeled off, it is difficult to partially repair with the adhesive 3. The flange 15 of the panel 1 and the flange 25 of the wheel house outer panel 2 are repaired by partially welding. In this case, welding is performed with a small spot welding gun, but both the flanges 15 and 25 require the above-described repair welding allowance, and there is a limit even if the flange length is reduced. The flanges 15 and 25 require a flange length of about 9 mm, including the welding allowance for repair and the application cost of the sealer 4, and the total length of the flanges 15 and 25 overlapped is about 11.5 mm.

  Therefore, the present invention can reduce the amount of protrusion to the vehicle inner side in the vehicle width direction while ensuring the minimum flange length necessary for welding for repairing the flange of the wheel house portion, and there is no variation in the amount of protrusion. An object of the present invention is to provide a wheel house structure of an automobile.

  The present invention forms a flange that bends and extends inwardly at the lower arch portion of the outer body plate of the automobile, and forms a flange that extends and bends inward at the outer end portion of the wheel house outer panel. In a wheel house structure of an automobile in which the inner surface of the lower end portion of the vehicle body outer plate facing each other and the outer surface of the outer end portion of the wheel house outer panel are bonded with an adhesive in a state where the flanges are superposed, the flange is Each of the arch portion of the vehicle body outer plate and the outer end portion of the wheel house outer panel is a bent flange extending at an acute angle and obliquely inward, and the front end portion of the bent flange of the wheel house outer panel is the outer edge of the vehicle body. It is made to superimpose on the front-end | tip part of the plate bending flange of a board (Claim 1). Since the flanges of the vehicle body outer plate and the wheel house outer panel are respectively bent and bent, it is possible to reduce the projecting amount of both flanges toward the vehicle inner side in the vehicle width direction while ensuring the necessary minimum flange length. In addition, since the slanted double-sided bending flanges are overlapped with each other, the vertical alignment of the vehicle body outer plate and the wheel house outer panel and the vehicle width direction can be easily performed, and variations in the protruding amount of the flange can be eliminated. .

  The upper half of the arch portion of the vehicle body outer plate and the upper half of the outer end portion of the wheel house outer panel are formed with the above-mentioned bent flanges, which are overlapped to form an arch of the above-mentioned vehicle body outer plate. A right angle flange extending inwardly at a substantially right angle from the right half flange portion and the lower half portion of the outer end portion of the wheel house outer panel is formed so as to overlap the right angle flanges. (Claim 2). A bending flange is formed in the upper half of the wheel house that may interfere with the wheel when the vehicle body and the wheel move relatively up and down, and a right angle flange is provided in the lower half that does not interfere with the wheel. Therefore, the moldability of the arch portion of the vehicle body outer plate and the outer end portion of the wheel house outer panel is good.

  According to the present invention, it is possible to further reduce the amount of protrusion to the vehicle inner side in the vehicle width direction while ensuring the minimum flange length necessary for welding for repair or the like of the flange of the wheel house portion, and variation in the amount of protrusion. Can be eliminated. Therefore, even if the wheel is moved to a position outside the vehicle in order to improve the appearance of the gap between the wheel and the wheel house portion and to secure the lateral width of the passenger compartment, it does not interfere with the wheel.

  An embodiment in which the present invention is applied to the rear wheel house portion of the automobile shown in FIG. 5 will be described. FIG. 1 shows a longitudinal section of the central upper half U of the rear wheel house at a position along the line Y-Y in FIG. 5. The rear wheel house is a substantially vertical quarter panel 1 constituting the rear part of the outer surface of the vehicle body. The outer end portion 20 of the arch-shaped wheel house outer panel 2 disposed on the inner side of the quarter panel 1 is coupled to the arch portion 10 formed at the lower end of the quarter panel 1. The wheel house outer panel 2 is provided with a general portion that is substantially horizontal in the vehicle width direction that constitutes the ceiling portion of the rear wheel house portion, and the outer end portion 20 is bent downward in a substantially vertical direction from the outer edge of the general portion. It is provided along the inner surface of the lower end of. A wheel house inner panel 5 that is provided in parallel with the outer panel 2 and forms a ceiling portion of the rear wheel house portion is coupled to the inner end portion 26 of the wheel house outer panel 2. Reference numeral 6 in FIG. 1 is a reinforcing panel that is installed on the inner side of the quarter panel 1 substantially in parallel to the quarter panel 1 and has a lower edge coupled to a position near the outer end 20 of the wheel house outer panel 2.

  FIG. 2 is an enlarged cross-sectional view of a connecting portion (C portion in FIG. 1) between the arch portion 10 of the quarter panel 1 and the outer end portion 20 of the wheel house outer panel 2, and the central upper half U of the rear wheel house portion. In the arch portion 10 of the quarter panel 1, a bent flange 11 having a substantially J-shaped cross section that is bent at an acute angle from the arch portion 10 toward the vehicle inner side and extends obliquely upward is formed. The proximal bent flange 11 is bent in an arc shape from the arch portion 10 and is formed in an inclined linear shape from the proximal end to the flange distal end portion. The bending angle α of the close bending flange 11 is set to about 30 degrees, and the flange length is about 9 mm.

  The outer end portion 20 extending substantially vertically downward of the wheel house outer panel 2 is formed with a bending flange 21 extending to the vehicle inner side at a bending angle of about 30 degrees, like the bending flange 11 of the quarter panel 1. The flange length is about 9 mm.

  The arch portion 10 of the quarter panel 1 and the outer end portion 20 of the wheel house outer panel 2 are arranged on the flange leading end portion of the flange plate 11 of the quarter panel 1, and the bent flange 21 of the wheel house outer panel 2. In this state, the inner surface of the arch portion 10 of the quarter panel 1 and the outer surface of the outer end portion 20 of the wheel house outer panel 2 are adhesively bonded by the adhesive 3. There is a gap corresponding to the thickness of the adhesive 3 between the arch portion 10 and the outer end portion 20.

  When the arch portion 10 of the quarter panel 1 and the outer end portion 20 of the wheel house outer panel 2 are coupled, the adhesive 3 is applied in advance along the inner surface of the arch portion 10 so that the quarter panel 1 and the wheel house outer panel are joined. 2 are assembled together in an oblique direction (arrow T in FIG. 2) along the inclination angle of the bending flanges 11 and 21.

  The both-side bent flanges 11 and 21 of the quarter panel 1 and the wheel house outer panel 2 that are overlapped have a gap in the vehicle width direction between the arch portion 10 and the outer end portion 20, so Further, the side bending flange 21 of the wheel house outer panel 2 protrudes toward the inside of the vehicle, and the sealer 4 covers the lower surface side of the overhanging portion of the side bending flange 21 and the flange front end portion of the side bending flange 11 of the quarter panel 1. Is applied to seal the overlapped portions of the double bent flanges 11 and 21.

  In the lower half of the front end and the lower half of the rear end of the rear wheel house indicated by L1 and L2 in FIG. 5, as shown in FIG. 3, from the arch portion 10 of the quarter panel 1 to the vehicle interior as in the conventional structure. While providing a right angle flange 14 that bends at a substantially right angle, a right angle flange 24 that bends at a right angle from the outer end 20 of the wheel house outer panel 2 to the inside of the vehicle is provided. The spot sealer 7 is filled between the inner surface of the arch portion 10 of the panel 1 and the outer surface of the outer end portion 20 of the wheel house outer panel 2, and both right-angled flanges 14 and 24 are spot welded.

  Further, from the front end lower half L1 to the center upper half U and from the rear end lower half L2 to the center upper half U of the rear wheel house part, both the flanges of the quarter panel 1 and the wheel house outer panel 2 are a right angle flange 14. , 24 to the bent flanges 11, 21.

  According to the present embodiment, the flanges of the arch portion 10 of the quarter panel 1 and the outer end portion 20 of the wheel house outer panel 2 are brought close to the bending flanges 11 and 21, respectively, in the central upper half U of the rear wheel house. Therefore, compared with the flange full length of both the flanges 11 and 21, the protrusion amount which protrudes in the vehicle width direction vehicle inner side can be made small. Substantially, the flange length of both flanges 11 and 21 is about 9 mm, and the total length of the flanges when they are overlapped is about 11.5 mm. However, both flanges 11 and 21 are inclined at an angle of about 30 degrees. Since it is bent to the side, the amount of protrusion to the inside of the vehicle in the vehicle width direction is about 6.5 mm.

  Therefore, by providing the front and rear flanges 11 and 21 having a small protrusion amount inward in the vehicle width direction in the center upper half U of the rear wheel house, it is possible to avoid interference with the wheels due to the vertical movement of the vehicle body. Can be arranged at a position on the vehicle outer side to improve the appearance of the gap between the wheel and the wheel house, and to secure the lateral width of the passenger compartment. Note that by increasing the inclination angle of both flanges 11 and 21 with respect to the horizontal line, the amount of protrusion of both flanges 11 and 21 toward the vehicle inner side in the vehicle width direction can be reduced. A tilt angle of about 60 degrees is optimal.

  Further, by overlapping the inclined bent flanges 11 and 21, the vertical alignment and the vehicle width alignment of the arch portion 10 of the quarter panel 1 and the outer end portion 20 of the wheel house outer panel 2 are not varied. Easy to do. For example, even if the wheel house outer panel 2 is displaced inward in the vehicle width direction with respect to the quarter panel 1, the front end of the bent flange 21 of the wheel house outer panel 2 is displaced obliquely upward. Since it is inclined about 60 degrees with respect to the horizon, it is only about one-half of the amount of displacement of the actual wheel house outer panel 2 toward the vehicle interior in the vehicle width direction.

  When repair work by welding is performed, as shown in FIG. 4, the both-side bent flanges 11 and 21 are once extended almost horizontally so as to be sandwiched by the welding gun SP, and the overlapping portion of both flanges 11 and 21 is welded by the welding gun SP. After spot welding, the work can be repaired with good workability by bending back to a predetermined inclination angle (about 60 degrees).

  Further, in this embodiment, the bending flanges 11 and 21 are formed only in the central upper half U of the wheel house part that may interfere with the wheels due to the vertical movement of the vehicle body, and the front end lower half L1 and the rear half that do not interfere with the wheels. In the lower end half L2, the right-angle flanges 14 and 15 are used. However, when only the center upper half U of the wheel house part is made into the bending flanges 11 and 21, the arch part 10 of the quarter panel 1 and the outer part of the wheel house outer panel 2 are out of the whole wheel house part to make the bending flange. The press formability of the end portion 20 is good, and the productivity can be improved.
