Description

  The present invention relates to a vehicle fender panel mounting structure in which a fender panel is mounted on left and right apron members forming an engine room.

  In an automobile, there is a case where a structure that absorbs an impact force applied to a falling object that falls on a fender panel at the time of a vehicle collision may be employed. For example, Patent Document 1 discloses a structure in which an inverted-shaped attachment portion is formed on a fender panel and the attachment portion is fastened to an apron member with a bolt. In Patent Document 1, an impact force is absorbed by bending of the attachment portion when a falling object enters from above.

JP-A-11-321718

  By the way, in the said conventional structure, since it becomes the operation | work which fastens with a volt | bolt in the state which aligned the attaching part of the fender panel with the apron member, attachment work is complicated and we are anxious about a cost rise and productivity fall.

  Further, in the conventional structure, when a fallen object enters from above, there is a possibility that the mounting portion may come into contact with the bolt when buckling is deformed, and it is necessary to take measures to enhance the impact force absorbing function. As one of the countermeasures, it can be considered that the bolt fastening portion has a structure that is easily buckled and deformed. However, in this case, there is a problem in that a feeling of rigidity when the fender panel is manually pushed during normal use is lowered.

  The present invention has been made in view of the above-described conventional circumstances, and can be easily performed without incurring an increase in cost and a decrease in productivity, and further, a reduction in rigidity when manually pushed. It is an object of the present invention to provide a mounting structure for a vehicle fender panel that can enhance the impact force absorbing function against a falling object without incurring.

  The present invention relates to an apron member disposed on both sides of the engine room in the vehicle width direction, a fender panel disposed on the outside of the apron member so as to cover the apron member, and a midway in the vehicle front-rear direction of the fender panel. In the vehicle fender panel mounting structure provided with a mounting leg portion fixed to the apron member, the mounting leg portion is directed downward from the fender panel toward the center of the vehicle when viewed from the front of the vehicle. The sloping wall has a sloping wall and a hanging wall extending downwardly following the sloping wall, and is fixed to the lower end portion of the dripping wall by being inserted into the flange portion of the apron member from the outside of the vehicle. The engaging part is formed.

  According to the mounting structure for a fender panel according to the present invention, the mounting leg of the fender panel is inclined to the vehicle center side downward, and the hanging wall is bent downward and extends downward following the inclined wall. Since the engaging portion fixed by inserting the flange portion of the apron member from the outside of the vehicle is formed at the lower end portion of the hanging wall, the apron is simply inserted into the flange portion. It can be attached to the member, and can be easily attached as compared with the case of conventional bolting. Further, the cost can be reduced and the productivity can be improved as much as bolts can be eliminated.

  Further, by inserting the mounting leg portion into the flange portion of the apron member, the fender panel can be temporarily fixed, and the mounting operation of the fender panel can be easily performed from this point.

  In the present invention, as described above, since the mounting leg portion has the inclined wall and the hanging wall extending downward following the inclined wall, when the fallen object enters the fender panel at the time of the vehicle collision, the inclined wall The sloping wall tends to fall down inward of the vehicle starting from the bent part of the wall and the drooping wall. At this time, if the hanging wall remains fixed to the apron member and the mounting leg simply bends to the inside of the vehicle, the amount of impact energy absorbed cannot be increased so much. Since an upward moment on the vehicle outer side acts on the lower end portion of the vehicle, the engaging portion is easily detached from the flange portion of the apron member during the course of bending. This makes it easy to control the buckling of the mounting leg, and as a result, the impact force absorbing performance can be enhanced by effective buckling deformation of the mounting leg. In this case, unlike the conventional case, the bolt fastening portion does not need to have a structure that is easily buckled and deformed, so that the rigidity feeling when the fender panel is pushed by hand is not reduced.

  A front pillar (not shown) is connected to the rear ends of the left and right apron members 2. The front end of the apron member 2 and the side member 3 are connected by a moment canceller 8.

  The upper part of the suspension tower 7 is coupled to the inside of the left and right apron members 2, and the lower part of the suspension tower 7 is coupled to the side member 3.

  The left and right apron members 2 have a structure in which a rectangular tube-like closed cross section is formed by joining the upper flange portions 2a and the lower flange portions 2b of the outer member 10 and the inner member 11 by welding. The upper flange portion 2a protrudes outward, and the lower flange portion 2b protrudes downward.

  A fender panel 14 that covers the apron members 2 is disposed outside the left and right apron members 2. The fender panel 14 is made of resin, and includes a fender body 14a having an exterior surface, and a front mounting portion 14b and a rear mounting portion 14c formed on the front edge and the upper rear edge of the fender body 14a. A stepped portion 14d is formed on the upper edge of the fender body 14a so as to face the outer edge portion 6a of the hood 6 so as to form a continuous surface.

  The front attachment portion 14b is attached to the moment canceller 8 via a front bracket 16, and the rear attachment portion 14c is attached to the hood bracket 9a. Moreover, although not shown in figure, the rear edge part of the said fender main body 14a is attached to the up-down direction middle part or lower end part of the front pillar. Further, a bumper mounting hole 14b 'is formed in the front mounting portion 14b.

  Mounting legs 14e fixed to the apron member 2 are integrally formed on the fender body 14a of the left and right fender panels 14.

  The mounting leg portion 14e has a plate shape extending in the vehicle front-rear direction, and is disposed in the vehicle front-rear direction midway portion of the fender body 14a and in the vertical direction midway portion.

  The mounting leg portion 14e includes an inclined wall 14f that inclines toward the lower part of the center of the vehicle following the fender body 14a, and a hanging wall 14g that bends and extends vertically downward following the inclined wall 14f when viewed from the front of the vehicle. And have. Here, the drooping wall 14g is not limited to the vertically downward direction, and may be displaced from the bent portion 14h with the inclined wall 14f toward the vehicle outer side. That is, when the hanging portion is displaced from the vertically lower side toward the vehicle inner side, a moment inward of the vehicle may act.

  A plurality of engaging portions 14i are formed at the lower end portion of the hanging wall 14g and are inserted into the upper flange portion 2a of the apron member 2 from the outside of the vehicle.

  Each engaging portion 14i is disposed on both the front and rear sides of the upper rib 14j that contacts the upper surface of the upper flange portion 2a, and the front and rear lower portions that contact the lower surface of the upper flange portion 2a. Ribs 14k, 14k, and claw portions 14m that are formed in the front and rear lower ribs 14k and engage with engagement holes 2c formed in the upper flange portion 2a.

  In order to assemble the fender panel 14, the engaging portions 14i are inserted into the upper flange portion 2a of the apron member 2 from the outside of the vehicle. Specifically, the upper flange portion 2a is inserted between the upper rib 14j and the lower rib 14k, and the claw portion 14m is engaged with the engagement hole 2c of the upper flange portion 2a. Thereby, the fender panel 14 is positioned on the apron member 2 and temporarily held. In this state, the front attachment portion 14b is attached to the moment canceller 8, and the rear attachment portion 14c is attached to the hood bracket 9a.

  According to the present embodiment, the mounting legs 14e of the left and right fender panels 14 are inclined and extended downward substantially vertically downward following the inclined wall 14f. Since a plurality of engaging portions 14i that are inserted and fixed to the upper flange portion 2a of the apron member 2 from the outside of the vehicle are formed at the lower end portion of the hanging wall 14g. The portion 14i can be attached by simply inserting the apron member 2 into the upper flange portion 2a of the apron member 2, and the attaching operation can be easily performed as compared with the conventional bolting. Moreover, since bolts can be made unnecessary, the cost can be reduced and the productivity can be improved accordingly.

  In the present embodiment, the engaging portions 14i are arranged on the upper rib 14j that contacts the upper surface of the upper flange portion 2a, and on both the front and rear sides of the upper rib 14j, before contacting the lower surface of the upper flange portion 2a. , Rear lower ribs 14k, 14k, and claw portions 14m formed in the front and rear lower ribs 14k and engaged with the engagement holes 2c formed in the upper flange portion 2a. 14 can be assembled to the apron member 2 while being positioned and temporarily fixed, the fender panel 14 can be easily attached, and the assembling accuracy can be increased.

  In the present embodiment, as described above, the mounting leg portion 14e has the inclined wall 14f and the hanging wall 14g extending vertically downward following the inclined wall 14f. Therefore, as shown in FIG. When the fallen object F enters the fender panel 14 from above, the inclined wall 14f tends to fall down inward of the vehicle starting from the bending point a between the inclined wall 14f and the hanging wall 14g. At this time, if the hanging wall 14g is fixed to the apron member 2 and the mounting leg portion 14e is simply bent inward of the vehicle, the amount of shock energy absorbed cannot be increased so much. Then, since the moment M acting on the outside of the vehicle acts on the lower end portion of the hanging wall 14g, the engaging portion is easily detached from the flange portion 2a of the apron member 2. Thereby, the impact force absorption performance can be enhanced by the effective buckling deformation of the mounting leg portion 14e.

  Further, since the mounting leg portion 14e has a plate-like shape extending in the front-rear direction, it is not necessary to make the bolt fastening portion easy to buckle and deform as in the prior art, and when the fender panel 14 is manually pushed during normal use. A feeling of rigidity can be secured.

  In the first embodiment, the engaging portion 14i is connected to the upper rib 14j, the front and rear lower ribs 14k and 14k disposed on both the front and rear sides of the upper rib 14j, and the front and rear lower ribs 14k. However, the engaging portion of the present invention is not limited to this. For example, the upper rib and the lower rib may be arranged so as to overlap each other in the vertical direction, or claw portions may be formed on both ribs.

  FIG. 6 is a view for explaining a fender panel mounting structure according to a second embodiment of the present invention. In the figure, the same reference numerals as those in FIG. 3 denote the same or corresponding parts.

  The mounting leg portion 14e 'of the fender panel 14 of the present embodiment is formed integrally with the stepped portion 14d of the fender panel 14, and is inclined to the vehicle center side downward following the stepped portion 14d. It has a structure having a wall 14f 'and a hanging wall 14g' extending bent substantially vertically downward following the inclined wall 14f ', and an engaging portion 14i' is formed at the lower end of the hanging wall 14g '. .

  Also in this embodiment, the mounting operation can be easily performed without causing an increase in cost and productivity, and further, an impact force absorbing function against a falling object can be achieved without causing a decrease in rigidity when pushed by hand. The effect similar to that of the first embodiment can be obtained.

  In the above embodiment, the case where the hanging wall 14g is bent substantially vertically downward from the lower end of the inclined wall 14f has been described. However, the hanging wall of the present invention is limited to a case where the hanging wall is bent substantially vertically downward. In short, if the bottom wall of the drooping wall can move outwardly due to the sloping wall falling down on the inside of the vehicle due to the impact force on the fender panel, for example, it is inclined slightly outside the vertical bottom. It doesn't matter.
