[0003]

[Problems to be solved by the device]

 However, in the mounting structure of the bumper to the vehicle body, when the side end portion of the bumper is moved outward in the vehicle width direction by the movement restricting member, a gap is formed between the bumper side end portion and the vehicle body so as not to contact the vehicle body. However, it is difficult to make the gap small because the side edges are not fixed to the vehicle body, and the gap may be conspicuous depending on the degree of mounting error in the vehicle width direction. There was a problem that hindered improvement.

The present invention has been made in view of the above point, and when the bumper receives an impact force due to a light collision or the like, the bumper can be moved outward in the vehicle width direction without damaging the vehicle body. Despite this, the aim is to reduce the gap between the side edge of the bumper and the vehicle body.

[0005]

[Means for Solving the Problems]

 To achieve the above object, the present invention attaches a bumper to a vehicle body through a bracket, and a tip of a lip that reduces a clearance between a side end of the bumper and the vehicle body is brought into contact with or close to the vehicle body. One of the ribs of the bumper and the vertical flange of the bracket is provided with an inclined surface on at least the vertical flange, and the rib and the bracket are brought into contact with each other on the inclined surface to restrict the bumper from moving inward in the vehicle width direction. The outward movement is allowed, and the engagement piece of the bracket and the claw of the bumper are engaged with each other to restrict the outward movement in the vehicle width direction.

[0006] Specifically, the solution provided by the present invention is directed to a vehicle body mounting structure of a bumper for mounting a side end portion of the bumper to a vehicle body through a bracket, and the bracket is a vehicle body mounting structure.

 With the above structure, in the present invention, the bumper side flange is connected to the horizontal flange of the bracket fixed to the side portion of the vehicle body by the fastening bolt that is inserted through the bumper side insertion hole and is fastened to the bracket side fastening hole. The side edge of the bumper is attached to the vehicle body.

In this case, at least the vertical flange of the vertical flange of the bracket and the rib of the bumper is formed with an inclined surface that inclines inward in the vehicle front-rear direction and outward in the vehicle width direction. Since the rib of the bumper and the vertical flange of the bracket come into contact with each other, the displacement of the bumper inward in the vehicle width direction is restricted. Further, since the locking piece of the bumper is locked to the inner surface of the claw of the bracket in the vehicle width direction, the displacement of the bumper outward in the vehicle width direction is prevented, and the bumper moves inward in the vehicle width direction. The outside is positioned. Therefore, variations in mounting error of the bumper in the width direction of the vehicle body are reduced, and the tip of the lip is always held in a state of abutting on or in the vicinity of the vehicle body, and a gap between the side end portion of the bumper and the vehicle body. The gap becomes smaller.

When an impact force acts on the bumper toward the vehicle body during a light collision or the like, the inclined surface causes the side end portion of the bumper to move inward in the vehicle longitudinal direction along the inclined surface in the vehicle width direction. A force that tries to move it outwardly acts, and the elastic locking piece elastically deforms and falls off from the bracket claws outward in the vehicle width direction, and the bumper side flange passes through the notch groove in the vehicle width direction. Fall out. As a result, the side end of the bumper moves outward in the vehicle width direction, and the elastic lip does not contact the vehicle body or elastically deforms even if it makes contact, so that the vehicle body width is not damaged. Move outward in the direction.

At the tip of the vertical flange 27, a bracket-side inclined surface 29 that inclines outward in the vehicle width direction toward the inside in the vehicle front-rear direction is formed.

Further, the bracket 15 extends in the same direction as the upper horizontal flange 25A and the lower horizontal flange 25B from a portion outside the vertical flange 27 at the side end of the base portion 19 on the outside in the vehicle width direction in the vehicle width direction. Two upper and lower claws 31, 31 protruding toward each other are provided.

The side end 5 of the bumper face 3 is provided with an upper side flange 33A and a lower side flange 33B which project substantially horizontally from the inner surface 5a in the vehicle body width direction inward in the vehicle body width direction, The upper side flange 33A and the lower side flange 33B are formed so as to be in contact with each other while sandwiching the upper side horizontal flange 25A and the lower side horizontal flange 25B of the bracket 15 from above and below. The lower flange 33B extends inward in the front-rear direction of the vehicle body. The upper flange 33A and the lower flange 33B constitute a bumper side flange.

The side end 5 of the bumper face 3 between the upper flange 33A and the lower flange 33B has elasticity that projects inward in the vehicle front-rear direction from a portion outside the vehicle width direction. The lip 35, the two upper and lower ribs 37, 37 protruding inward in the vehicle width direction from the vehicle width direction inner surface 5a, and the portion corresponding to the claws 31 of the bracket 15 on the vehicle body width direction inner surface 5a Two upper and lower engaging pieces 39, 39 having elasticity projecting inward in the front-rear direction are provided, respectively. The rib 37 of the bumper face 3 is formed with bumper face-side inclined surfaces 41, 41 that are inclined in the same direction as the bracket-side inclined surface 29. The bracket-side inclined surface 29 and the bumper face-side inclined surface 41 form an inclined surface in the structure for mounting the bumper on the vehicle body 7 according to this embodiment.

In the upper flange 33 A and the lower flange 33 B, a bumper face side insertion hole 43 is formed as a bumper side insertion hole which is formed at a portion corresponding to the bracket side fastening hole 23 and into which the fastening bolt 21 can be inserted. 43 and notch grooves 45, 45, one end of which communicates with the bumper face side insertion hole 43 and the other end of which opens at the vehicle width direction side ends of the upper and lower flanges 33A, 33B, respectively. The notch groove 45 is formed so as to open in the same direction as the bracket-side inclined surface 29, and when a force for moving the bumper 1 outward along the bracket-side inclined surface 29 is applied outward. The fastening bolt 21 is formed so as to be deformable so as to pass therethrough.

In the side end 5 of the bumper face, the upper flange 33A is lower than the upper horizontal flange 25A in the bracket 15 by the fastening bolts 21 inserted in the bracket side fastening hole 23 and the bumper face side insertion hole 43. The flanges 33B are respectively fastened to the lower horizontal flanges 25B, and the tips of the lips 35 of the bumper face 3 come into contact with or come close to the vehicle body 7, and the bumps 41 on the bumper face side of the ribs 37 and the bracket side of the vertical flange 27. The inclined surface 29 is in contact with each other, and the locking piece 39 of the bumper face 3 is configured to be mounted in a state of being locked to the inner surface of the claw 31 of the bracket 15 in the vehicle width direction.

Next, a mounting structure of the bumper to the vehicle body 7 will be described. As shown in FIGS. 3 to 5, the bumper 1 is attached to the vehicle body 7 by connecting the side ends 5 of the bumper face 3 to the brackets 15 fixed to the left and right front side portions 9 of the vehicle body 7. That is, the upper flange 33A is fastened to the upper horizontal flange 25A of the bracket 15 from above by the fastening bolts 21 that are inserted through the bumper face side through holes 43 and are fastened into the bracket side fastening holes 23, and the lower flange 33B is fastened. Are fastened to the lower horizontal flanges 25B from below.

In this case, the vertical flange 27 of the bracket 15 and the ribs 37 of the bumper face 3 respectively include a bracket-side inclined surface 29 and a bumper face which are inclined inward in the vehicle width direction and outward in the vehicle width direction. Since the side inclined surface 41 is formed and the both inclined surfaces come into contact with each other, the displacement of the bumper 1 inward in the vehicle width direction is restricted.

Further, since the locking piece 39 of the bumper face 3 is locked to the inner surface of the claw 31 of the bracket 15 in the width direction of the vehicle body, displacement of the bumper 1 outward in the vehicle width direction is prevented, The bumper 1 is positioned inward and outward in the vehicle width direction. Therefore, the variation in the mounting error of the bumper 1 in the vehicle width direction is reduced, and the bumper face 3 is always held in a state where the tip of the lip 35 is in contact with or close to the vehicle body 7. The gap between the side end portion 5 of the face 3 and the vehicle body 7 becomes smaller.

As shown in FIG. 6, when an impact force is applied to the bumper face 3 during a light collision or the like, the side surface 5 of the bumper face 3 is moved by the bracket side inclined surface 29 and the bumper face side inclined surface 41. A force that moves the vehicle in the vehicle longitudinal direction inward along the inclined surfaces 29, 41 on the bracket side and the bumper face side and moves it outward in the vehicle width direction acts on the locking piece 39 having elasticity. Elastically deforms and falls off from the pawl 31 of the bracket 15 outward in the vehicle width direction, and further, the upper flange 33A and the lower flange 33B fall off outward in the vehicle width direction via the notch groove 45. As a result, the side end portion 5 of the bumper face 3 moves outward in the vehicle width direction as shown by the arrow A, and the elastic lip 35 of the bumper face 3 does not contact the vehicle body 7, or Even if they come into contact with each other, they are elastically deformed and thus move outward in the vehicle width direction without damaging the vehicle body 7.

As described above, according to the present embodiment, when an impact force such as a light collision is applied to the bumper face 3, the side end portion 5 of the bumper face 3 is moved outside the vehicle width direction along the bracket side inclined surface 29. It is possible to move it to the side and drop it from the bracket 15 so that the elastic lip 35 does not damage the vehicle body 7.

Moreover, the claws 31 of the bracket 15 and the locking pieces 39 of the bumper face 3, and the bracket-side inclined surface 29 and the bumper-face-side inclined surface 41 reduce variations in mounting error of the bumper face 3 to the vehicle body 7. Since the bumper face 3 can be moved outward in the vehicle width direction without coming into contact with the vehicle body 7, the lip 35 separates the side end 5 of the bumper face 3 from the vehicle body 7. It is always possible to reduce the gap between them, and the bumper 1 can be attached to the vehicle body 7 with a good appearance.

The bumper 1 according to this embodiment may be attached to the rear part of the vehicle body 7.

Further, the inclined surface in the mounting structure of the bumper 1 to the vehicle body 7 according to the present embodiment has a bracket side inclined surface 29 on the vertical flange 27 of the bracket 15 and a bumper face side on the rib 37 of the bumper face 3. The inclined surface 41 is not limited to the above embodiment, but may be formed only on the vertical flange 27.

[0027]

[Effect of device]

 As described above, according to the present invention, the elastic lip of the bumper comes into contact with or comes close to the vehicle body, while the rib of the bumper and the vertical flange of the bracket are directed inward in the front-rear direction of the vehicle body in the vehicle width direction. The bumper has an elastic contact piece that contacts the outside, and the elastic locking piece of the bumper engages with the bracket claw, and a cutout groove is formed in the bumper-side insertion hole. When a force is applied, the locking piece is disengaged from the pawl, and the side end of the bumper is disengaged from the bracket, so that the lip does not contact the vehicle body or elastically deforms even if it contacts the vehicle body width. It can be moved outward in the direction, and the bumper can be prevented from scratching the vehicle body.

Moreover, since the claws of the bracket and the locking pieces of the bumper are locked, and the bracket and the bumper are in contact with each other on the inclined surface that inclines outward in the vehicle width direction toward the inside in the vehicle front-rear direction, It is possible to reduce variations in mounting error of the bumper to the vehicle body by positioning the vehicle body widthwise outward and inward. Therefore, although the bumper can move outward in the vehicle width direction without damaging the vehicle body, the lip can always reduce the gap between the side end of the bumper and the vehicle body. This makes it possible to attach the bumper to the vehicle body with a good appearance.
