Description

  The present invention relates to a bumper mounting structure that can prevent paint peeling and scratches that occur when a bumper face is mounted.

As a technology related to the bumper mounting structure, there is a technique in which a hole is formed in the front and rear direction in a rear combination outer panel to which a rear combination lamp is mounted, and a bumper is mounted by locking a locking claw on the back side of the bumper in this hole. (For example, refer to Patent Document 1).
JP 2000-264145 A

  However, in Patent Document 1, since the distance between the rear combination lamp and the bumper mounting position is long, the positional relationship between the rear combination lamp and the bumper is likely to shift during assembly.

  In order to prevent such a positional shift between the bumper and the light, a bracket is integrally attached to the lower side of the light along the light, and the insertion portion of the bumper face is inserted between the light and the bracket while being attached to the bracket. There is a bumper mounting structure to be locked. As shown in FIG. 9, the conventional structure adopting this structure has a locking claw 102 protruding to the light 101 side on a metal bracket 100, and this locking claw 102 is inserted into the bumper face 103. It is configured to be locked in a locking hole 105 formed in the portion 104.

  However, in the structure in which the locking claw that protrudes to the light side is formed on the bracket as described above, after the insertion portion of the bumper face is once placed on the locking claw, the locking hole is locked to the locking claw. Therefore, when it is placed on the locking claw, it may move to the light side and come into contact with the light, resulting in paint peeling or damage.

  Accordingly, an object of the present invention is to provide a bumper mounting structure that can prevent paint peeling and scratches that occur when a bumper face is mounted.

  In order to achieve the above object, according to the first aspect of the present invention, a bracket (for example, the beam bracket 15 in the embodiment) is integrally attached to the lower side of the light (for example, the headlight 10 in the embodiment) along the light. The bumper mounting structure is configured such that an insertion portion (for example, the insertion portion 32 in the embodiment) of the bumper face (for example, the bumper face 12 in the embodiment) is inserted between the light and the bracket and is locked to the bracket. The bracket is provided on a bracket main body (for example, the bracket main body 21 in the embodiment) and the light side of the bracket main body, and on the bracket main body, the protrusion (for example, the protrusion 28 in the embodiment). A locking claw (for example, the locking claw 22 in the embodiment) having The insertion portion of the damper face is inserted between the locking claw and the bracket main body, and is locked to the protrusion at a locking hole (for example, the locking hole 33 in the embodiment). .

  According to a second aspect of the present invention, in the first aspect of the present invention, the locking claw has a shape extending to the front side in the insertion direction of the bumper face after rising from the bracket body portion to the light side. In addition, the protrusion is formed on the distal end side of the extension.

  The invention according to claim 3 is characterized in that, in the invention according to claim 1 or 2, the bracket is integrally formed of a synthetic resin material.

  According to the first aspect of the present invention, since the locking claw is on the light side of the bracket main body portion and has the protrusion on the bracket main body portion side, the insertion portion of the bumper face is connected to the locking claw and the bracket main body. The bumper face does not move to the light side when inserted between the projection and the projection in the latch hole. Therefore, since the bumper face does not come into contact with the light at the time of mounting, it is possible to prevent paint peeling and scratches generated on the bumper face.

  According to the second aspect of the present invention, the locking claw has a shape extending to the front side in the insertion direction of the bumper face after rising from the bracket main body portion to the light side, and is projected to the distal end side of the extension. Since the portion is formed, when the protrusion is brought into contact with the insertion portion when the insertion portion of the bumper face is inserted, a portion other than the protrusion becomes difficult to contact the insertion portion. Therefore, it is possible to reliably prevent paint peeling and scratches that occur on the bumper face.

  According to the invention of claim 3, since the bracket is integrally formed of a synthetic resin material, it is easily formed into a shape in which a locking claw having a protrusion on the bracket body portion side is provided on the light side of the bracket body portion. be able to. In addition, the weight of the bracket can be greatly reduced.

  A bumper mounting structure according to an embodiment of the present invention will be described below with reference to the drawings. In addition, before and after in the following description is before and after the vehicle moves forward.

  Specifically, the bumper mounting structure of the present embodiment is applied to the front portion of the vehicle, that is, the front bumper. 1 and 2 show the front part of the vehicle. In the front part of the vehicle, headlights (lights) 10 are provided on both sides in the vehicle width direction, and a bonnet 11 is provided from between these headlights 10 to the rear. The bumper face 12 is attached to the lower side of the headlight 10 and the bonnet 11.

  As shown in FIG. 3, a beam bracket (bracket) 15 is integrally attached to the lower side of the headlight 10 via a plurality of attachment portions 14 provided at the lower portion thereof. The headlight 10 is attached to the front side member 18 on the side of the vehicle body 19 in a state of being a subassembly together with the bracket 15. As shown in FIG. 4, the front end edge portion 17 of the lower surface 16 of the headlight 10 has a shape that is inclined so as to be positioned on the upper side as it is on the front side. For convenience of explanation, the vehicle body 19 indicates a portion excluding the bumper face 12 of the vehicle.

  The beam bracket 15 has a curved shape as shown in FIG. 5 along the front edge 17 that forms the curved shape of the lower surface 16 of the headlight 10. It is fixed to the headlight 10 in a state where a predetermined gap is formed between the lower surface 16 and a position almost directly below.

  The beam bracket 15 has a curved shape along the front edge 17 of the lower surface 16 of the headlight 10 and a bracket body 21 in which the upper surface 20 facing the front edge 17 is disposed substantially horizontally, and the bracket body 15 21 has a locking claw 22 provided on the headlight 10 side, that is, on the upper side.

  As shown in FIGS. 4 and 6, the locking claw 22 includes a base portion 25 that rises from both sides in the vehicle width direction of the rear end edge portion 24 of the upper surface portion 20 of the bracket body portion 21 to the upper side, that is, the headlight 10 side. An extension plate portion 26 that extends forward from an upper end portion of the base portion 25, that is, an end portion on the headlight 10 side, and a front end portion that is opposite to the base portion 25 of the extension plate portion 26, that is, the front end portions, are And a projecting portion 28 projecting downward from the intermediate position of the erected plate portion 27 in the vehicle width direction, that is, toward the bracket body portion 21 side. A plurality of such locking claws 22 are formed at two positions with a gap in the vehicle width direction. As will be described later, the bumper face 12 is inserted between the headlight 10 and the beam bracket 15 from the front to the rear and is locked to the beam bracket 15. After rising from the bracket body 21 to the headlight 10 side, the bumper face 12 has a shape extending toward the front side in the insertion direction, and a protrusion 28 is formed on the leading end side of the extension. .

  Here, the beam bracket 15 having the above shape is integrally formed by injection molding, and is made of a hard synthetic resin material.

  As shown in FIG. 4, the bumper face 12 includes a folded portion 31 having a shape folded back from the upper end portion of the front plate portion 30 and an insertion portion 32 extending rearward from the lower end portion of the folded portion 31. The insertion portion 32 has a locking hole 33 penetrating in a vertical direction at a predetermined position. Here, a plurality of the locking holes 33 are specifically formed at two positions at intervals in the vehicle width direction. The coating is applied from the front surface of the front plate portion 30 to at least the rear side of the folded portion 31 and the upper side of the insertion portion 32 that are continuous with the front plate portion 30.

  In the bumper mounting structure of the present embodiment, when the bumper face 12 is mounted on the vehicle body 19 side, the bumper face 12 is mounted on the vehicle body 19 side with the horizontal direction from the vehicle front toward the vehicle rear as described above. Become.

  At this time, the insertion portion 32 arranged on the insertion tip side of the bumper face 12 is guided between the headlight 10 and the beam bracket 15 while being guided by the upper surface portion 20 of the bracket body portion 21 as shown in FIG. Therefore, it is inserted between the locking claw 22 of the beam bracket 15 and the upper surface portion 20 of the bracket body portion 21. Then, as shown in FIG. 7, the insertion portion 32 comes into contact with the protruding portion 28 that protrudes below the locking claw 22 of the bracket 15, and pushes this up to mainly elastically deform the extension plate portion 26. And the insertion part 32 is further inserted with the latching claw 22 being in this state. At this time, since the locking claw 22 is connected to the bracket main body 21 side only by the base portion 25 at the rear end portion, when it is placed on the insertion portion 32 by the protruding portion 28, the protruding portion 28 excluding the base portion 25, The installation plate portion 27 side of the installation plate portion 27 and the extension plate portion 26 is lifted, and as a result, the insertion portion 32 is inserted without contacting portions other than the projection portion 28.

  When the protrusion 28 is positioned in the locking hole 33 of the insertion portion 32, the protrusion 28 is lowered by the elastic force of the locking claw 22 and enters the locking hole 33 as shown in FIG. The part 32 is locked.

  The bumper face 12 is attached to the vehicle body 19 via the beam bracket 15 or the like by engaging the insertion portion 33 of the bumper face 12 with respect to the beam brackets 15 on both sides in the vehicle width direction. Become.

  According to the bumper mounting structure of the present embodiment described above, the locking claw 22 has the projection 28 on the headlight 10 side, that is, the upper side of the bracket body portion 21 and on the bracket body portion 21 side, that is, the lower side. Therefore, when the insertion portion 32 of the bumper face 12 is inserted between the locking claw 22 and the bracket main body portion 21 and locked to the projection portion 28 in the locking hole 33, the bumper face 12 is moved to the headlight 10. It does not move to the side or upper side. Therefore, since the bumper face 12 does not come into contact with the headlight 10 at the time of mounting, it is possible to prevent paint peeling and scratches that occur on the bumper face 12.

  In addition, after the locking claw 22 rises from the bracket main body 21 to the headlight 10 side, the locking claw 22 has a shape extending toward the front side in the insertion direction of the bumper face 12, and a protrusion 28 is formed on the distal end side of the extension. Thus, when the insertion portion 32 of the bumper face 12 is inserted, if the projection 28 comes into contact with the insertion portion 32, the portion other than the projection 28 is less likely to contact the insertion portion 32. Therefore, it is possible to reliably prevent paint peeling and scratches that occur on the bumper face 12.

  Further, since the beam bracket 15 is integrally formed of a synthetic resin material, it is easily formed in a shape in which a locking claw 22 having a projection 28 is provided on the bracket body 21 side on the headlight 10 side of the bracket body 21. be able to. In addition, the weight of the beam bracket 15 can be greatly reduced.

  In the above embodiment, the bumper structure of the present invention is applied to the front bumper. However, the bumper structure can be applied to a rear bumper.
