Description

The present invention relates to a cover member mounting structure for a vehicle bumper, and more particularly to a cover member mounting structure for mounting a cover member for covering the opening to an opening formed in the vehicle bumper.

  There are specifications for a vehicle bumper that are equipped with a fog lamp, and specifications that are not equipped with a fog light. If the specification is equipped with a fog lamp, attach the fog lamp to the vehicle bumper. If the specification does not allow the fog lamp to be installed, the cover member (fog cap) is used to hide the fog lamp mounting portion (opening) of the vehicle bumper. ). Note that the fog lamp mounting portion of the vehicle bumper has a common shape regardless of the presence or absence of the fog lamp (see FIG. 1).

  Conventionally, when the cover member is assembled to the vehicle bumper (front bumper and rear bumper), as shown in FIGS. 14 and 15, recessed fog lamp mounting portions (fog lamp housing recesses) on the left and right sides of the vehicle bumper are shown. 16, three mounting holes (engaged portions made of narrow long holes extending in the arc direction) 31 are provided so as to protrude to the back side of the cover member 32 as shown in FIG. The cover members 32 are fixed by inserting the engaging portions 33 and clicking and engaging the fog lamp mounting portions 30 with each other. In addition, the above-mentioned three attachment holes 31 are each normally arrange | positioned with the angular space | interval which makes about 120 degrees along the circumferential direction. The three engaging portions 33 of the cover member 32 that are click-engaged with the mounting holes 31 have the same shape as each other, and are provided so as to protrude from the peripheral portion of the cover member 32 to the back surface side. A projecting piece 34, an engaging claw 35 having a substantially chevron-shaped cross section provided at the tip of the projecting piece 34, and the engaging claw 35 are enclosed in a substantially U shape so that the engaging claw 35 can be elastically biased. Thus, it is configured with a slit 36 formed in the protruding piece 34.

On the other hand, as a technique related to the structure for attaching the cover member to the vehicle bumper, for example, an attachment structure for detachably attaching the lamp hole cover to the lamp hole opened in the bumper of the automobile (for example, Japanese Patent Laid-Open No. 2002-2002). 36984) and a mounting structure (see, for example, Japanese Utility Model Laid-Open Nos. 5-67556 and 5-67557) in which a fitting object is fitted and attached to the opening of the bumper.
JP 2002-36984 A Japanese Utility Model Publication No. 5-67556 Japanese Utility Model Publication No. 5-67557

  When it is necessary to change the design of the vehicle bumper due to various design requirements, the three attachment holes 31 having the same configuration may not be provided in the fog lamp attachment portion 30. For example, a relatively wide opening (for example, an opening 20 as shown in FIG. 8) at a location corresponding to one of the three mounting holes 31 due to a request for air intake inside the vehicle bumper or the like. May need to be provided. In such a case, a state where only one engaging portion 33 of the cover member is hooked on the upper edge α of the periphery of the opening 20 (see FIG. 8) (the protruding piece provided with the engaging claw 35). Under the condition that the position 34 is not securely held in the mounting hole 31, the cover member 32 must be fixed.

  In such a case, the following problems occur. First, the engaging claw 35 of the cover member 32 that is click-engaged with the upper end edge of the opening 20 is weakly engaged with the upper end edge α of the opening 20 (that is, the engaging force is small). There is a possibility that the engaged state between the pawl 35 and the opening 20 is easily released. In other words, when the cover member 32 is assembled, the engaging claw 35 can be easily elastically biased by providing the slit 36 in the projecting piece 34 so that the assembling work can be easily performed. Therefore, the engaging force under the click engagement state is relatively weak, and the click engagement state may be easily released only by hooking the engagement claw 35 on the upper end edge α of the opening 20.

  Further, when one mounting hole 31 of the vehicle bumper is changed to a relatively wide and wide opening 20, the opening 20 can be seen as a mere punching opening in appearance. It becomes difficult to recognize as. Therefore, the insertion position (insertion position) of the engagement claw 35 of the cover member 32 is not correctly determined, and the engagement claw 35 is easily caught on the peripheral edge (for example, the edge on the upper end side) of the attachment hole 31. Assembling work of the cover member 32 to 30 may be difficult.

  Further, after the cover member 32 is assembled to the fog lamp mounting portion 30, the position of the cover member 32 at the opening of the fog lamp mounting portion 30 is not restricted in both the vehicle width direction and the vehicle front-rear direction. There is a possibility of rattling for the bumper for the vehicle.

  The present invention has been made to eliminate such problems, and the object thereof is to improve the workability of assembling the cover member to the vehicle bumper, and to cover the vehicle bumper. Provided is a cover member mounting structure for a vehicle bumper that can prevent the member from falling off and can suppress the backlash of the cover member with respect to the vehicle bumper after the cover member is assembled to the vehicle bumper. There is.

In order to achieve the above object, according to the present invention, in the cover member mounting structure for mounting a cover member for covering the opening to the opening formed in the vehicle bumper, the opening of the vehicle bumper is provided. While engaging portions are provided at a plurality of locations on the periphery of the cover member, engaging portions corresponding to the engaged portions of the vehicle bumper are provided at a plurality of locations on the back side of the cover member, and a plurality of engagements of the cover member are provided. One of the engaging portions is click-engaged with the engaged portion of the vehicle bumper using the entire elastic deflection of the cover member, and the cover member except for the one engaging portion is clicked. The engaging portion is configured to be click-engaged with the engaged portion of the vehicle bumper by using a partial elastic deflection of only the engaging portion.
In the present invention, the inclined guide formed at the peripheral portion of the opening of the vehicular bumper at the engaged portion of the vehicular bumper to which the one engaging portion of the cover member is engaged. A guide rib having a surface and a first pair of positioning ribs formed on both side portions of the guide rib are provided, and the first pair of positioning members is provided on the one engaging portion of the cover member. A second pair of positioning ribs that contact the ribs is provided.
In the present invention, the one engaging portion of the cover member is constituted by a projecting piece projecting toward the back surface side of the cover member and an engaging claw formed on the projecting piece, Except for one engaging portion, the engaging portion of the cover member has a protruding piece projecting toward the back side of the cover member, an engaging claw formed on the protruding piece, and the engaging claw is elastically biased. In order to be able to do so, it is comprised with the slit formed in the said protrusion piece so that the said engagement nail | claw may be enclosed in substantially U shape.
In the present invention, the engaging claw formed in the one engaging portion of the cover member has a substantially chevron cross-sectional shape, and the engaged surface of the engaged portion and the engaging portion are The engaging surface is in a surface contact state.
In the present invention, the engaging surface of the engaging claw is arranged substantially in parallel to a plurality of crosspieces provided so as to extend parallel to each other in the cover member.

  According to the first aspect of the present invention, the engaged portions are provided at a plurality of locations on the periphery of the opening of the vehicle bumper, and the engaged portions of the vehicle bumper are respectively provided at a plurality of locations on the back side of the cover member. An engaging portion is provided, and one engaging portion of the plurality of engaging portions of the cover member is click-engaged with the engaged portion of the vehicle bumper by utilizing the entire elastic deformation of the cover member. Since the engagement portion of the cover member excluding one engagement portion is configured to be click-engaged with the engaged portion of the vehicle bumper using the partial elastic deflection of only the engagement portion, The click engagement using the entire elastic deflection (bending) makes it possible to keep the engagement state after the click engagement (click engagement state) strong, and thus the engaged portion can be opened relatively wide. Even if it is a hole, it may impair the assembly work of the cover member. No, it is possible to easily disengaged the engagement claw of the cover member from the peripheral edge of the opening.

  According to a second aspect of the present invention, the engagement portion of the vehicle bumper to which the one engagement portion of the cover member is engaged is formed at the peripheral portion of the opening of the vehicle bumper. A guide rib having an inclined guide surface and a first pair of positioning ribs formed on both side portions of the guide rib are provided, and a first pair of positioning is provided on the one engaging portion of the cover member. Since the second pair of positioning ribs abutting against the ribs for providing is provided, the engaging claws are covered with the cover of the vehicle bumper by the guide action of the engaging claws of the cover member by the inclined guide surfaces of the guide ribs. It is possible to smoothly guide to the engaging portion, and therefore it is possible to improve the assembling workability of the cover member. Further, by bringing the first and second pair of positioning ribs into contact with each other, the position of the cover member can be regulated in a direction orthogonal to these ribs, that is, in the vehicle width direction, and the first A pair of positioning ribs are brought into contact with the peripheral portion of the opening of the vehicle bumper and the peripheral portion is sandwiched between the rib and the engaging claw, thereby restricting the position of the cover member in the vehicle longitudinal direction. It becomes possible.

  According to a third aspect of the present invention, the one engaging portion of the cover member has a projecting piece projecting from the cover member toward the back side of the cover member, and an engaging claw formed on the projecting piece. And an engaging portion of the cover member excluding the one engaging portion, a protruding piece projecting toward the back side of the cover member on the cover member, and an engaging claw formed on the protruding piece, Since the engaging claw is constituted by a slit formed in the protruding piece so as to surround the engaging claw in a substantially U shape so that the engaging claw can be elastically biased, the engaged portion is opened with a relatively large wide opening. In the case of a hole, stable engagement is achieved by clicking and engaging the one engagement portion (that is, the engagement portion not provided with a slit for imparting elastic deflection) at the periphery of the opening. While being able to maintain the state, other engaging portions (ie, providing elastic deflection) The engagement portion provided with a slit for the purpose) has sufficient elasticity so that it can be clicked with a relatively weak insertion force (insertion force), and the assembly workability is impaired. It can be avoided.

  According to a fourth aspect of the present invention, the engaging claw formed in the one engaging portion of the cover member has a substantially chevron cross-sectional shape, and the engaged portion and the engaging portion are click-engaged. Since the engaged surface of the engaged portion and the engaging surface of the engaging portion are brought into a surface contact state when combined, a sufficiently large engagement force after click engagement is ensured. It is possible to achieve a click engagement state in which the engaging portion is unlikely to be detached from the engaged portion.

  Further, according to the fifth aspect of the present invention, since the engagement surface of the engagement claw is disposed substantially parallel to the plurality of crosspieces provided so as to extend in parallel with each other in the cover member, The elastic deformation (bending) of the entire member can be obtained easily and smoothly.

  Hereinafter, a cover member mounting structure in a vehicle bumper according to an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 shows a front bumper assembly 1 having a cover member mounting structure in a vehicle bumper according to an embodiment of the present invention. As shown in FIG. 1, the front bumper (vehicle bumper) 2 constituting the main body of the front bumper assembly 1 is provided with openings 3 for accommodating fog lamps on the left and right sides thereof. These openings 3 are front opening openings of a bottomed cylindrical recess 4 formed on both the left and right sides of the front bumper 2. Thus, in the case of a specification for mounting a fog lamp (not shown), the fog lamp is accommodated in the above-described recessed portion 4 and mounted in a fixed state with clips (using the three clip insertion holes 26 shown in FIG. 8). When the fog lamp is not used, a cover member (fog cap) 6 is attached to each of the recessed portions 4 so that the opening 3 is covered with the cover member 6.

  Here, the cover member 6 will be described with reference to FIGS. That is, the cover member 6 is formed of, for example, an integrally molded product made of synthetic resin, and as shown in FIGS. 2 to 4, an annular frame portion 7 having a ring shape and a space surrounded by the annular frame portion 7. For example, four horizontal crosspieces 8 laid in parallel to cross each other and the back surface of the annular frame portion 7 are integrally formed so as to protrude to the back surface side at a distance of about 120 °. It is comprised from three engaging parts 9a, 9b, 9c.

  One engagement portion of the cover member 6, for example, one engagement portion 9 a on the upper end side shown in FIGS. 2 to 4, as clearly shown in FIG. 5, extends from the annular frame portion 7 of the cover member 6 to the cover member 6. The projecting piece 10 protrudes toward the back surface side, and an engaging claw 11 formed on the upper surface 10a of the projecting piece 10 at a position away from the annular frame portion 7 by a predetermined distance. Note that a U-shaped slit for facilitating the elastic bias is not provided around the engaging claw 11 in the engaging portion 9a. A pair of side edge portions of the upper surface 10 a of the projecting piece 10 extends upward from the projecting piece 10 and extends from the annular frame portion 7 to a position near the engaging claw 11 at both side positions of the engaging claw 11. Positioning ribs 12, 12 (corresponding to the second pair of positioning ribs according to claim 2) are provided, and the above-mentioned pair of ribs 12, A pair of reinforcing ribs 13 respectively corresponding to 12 is provided (see FIGS. 2, 5, and 11). These reinforcing ribs 13 extend downward from both side portions of the lower surface 10b of the projecting piece 10.

  Further, the engaging claw 11 described above has a substantially chevron-shaped cross section as shown in FIG. 6, and the engaging surface 11 a is formed so as to be substantially perpendicular to the protruding piece 10. In FIG. 6, the engaging claw 11 ′ indicated by the alternate long and short dash line is an engaging claw having a mountain-shaped cross section that has been conventionally used (an engaging claw that engages the engaged portion in a line contact state). ). The protruding piece 10 is disposed substantially parallel to the four horizontal beam portions 8 provided so as to extend in parallel with each other, and the engaging surface 11a of the engaging claw 11 is provided with the horizontal beam. It is arranged substantially parallel to the part 8. Thereby, the above-mentioned engaging claw 11 is elastically deformed as a whole of the cover member 6 (specifically, elastically centered on the diameter portion of the annular frame portion 7 in the direction parallel to the horizontal rail portion 8). It is configured such that it can be click-engaged with an engaged portion of a front bumper 2 to be described later using bending deformation.

  Further, the engaging portions 9b and 9c except for the engaging portion 9a have the same structure as conventionally used, and as shown in FIG. The projecting piece 15 projecting toward the back surface side of this, the engaging claw 16 formed on the projecting piece 15 (see FIG. 7), and the engaging claw 16 are substantially arranged so that the engaging claw 16 can be elastically biased. The slit 17 is formed in the protruding piece 15 so as to surround the U-shape. The reason why the engaging portions 9b and 9c have the same structure as the conventional structure is as follows. That is, the portion where the engaging claws 16 of the engaging portions 9b and 9c are click-engaged is not a relatively large wide hole. Therefore, if the same structure as the engaging portion 9a is used, the insertion force (difference) Since the assembling workability of the cover member 6 is impaired, the slit 17 is not filled, and the elastic bending of the base portion of the holding piece β (see FIG. 7) that holds the engaging claw 16 is not performed. Is used).

  On the other hand, as shown in FIG. 8, the peripheral edge of the opening 3 of the front bumper 2 (the peripheral edge of the rear wall surface 4 a of the fog lamp housing recess 4) is located at an angular interval of about 120 ° along the circumferential direction. In addition, engaged portions 18a, 18b, and 18c corresponding to the three engaging portions 9a, 9b, and 9c of the cover member 6 are provided. In the present embodiment, the engaged portion 18a to which the one engaging portion 9a of the cover member is engaged is provided at the upper end portion of the back wall surface 4a of the recessed portion 4, for example, relatively for air intake. The engagement portion 18b, 18c other than the engagement portion 18a is substantially the same as the structure conventionally used, as shown in FIG. In the same manner, each is composed of an arc-shaped attachment hole (long hole) 21 and an engaged piece 22 formed so as to protrude into the attachment hole 21.

  Further, as shown in FIGS. 8 to 10, the engaged portion 18 a to which one engaging portion 9 a of the cover member is engaged is a peripheral portion of the back wall surface 4 a of the recessed portion 4 and the A guide rib 24 having an inclined guide surface 23 formed at the upper edge of the opening 3 of the front bumper 2, that is, the upper edge of the inner wall 4 a of the recessed portion 4, at the upper edge α corresponding to the opening 20. A pair of positioning ribs 25, 25 (corresponding to the first pair of positioning ribs according to claim 2) formed in parallel on both side portions of the guide rib 24 are provided.

  8 to 10, reference numeral 26 denotes a clip insertion hole used for attaching a fog lamp (not shown) to the back wall surface 4a of the recessed portion 4, and 27 denotes a wiring hole used for pulling out the wire harness.

  When the cover member 6 is attached to the opening 3 so as to cover the opening 3 of the front bumper 2, the cover member 6 is moved toward the opening 3 so that the engaging portion 9 a of the cover member 6 is an upper portion of the opening 20. And the engaging portions 9b, 9c of the cover member 6 are inserted into the long holes 21 of the engaged portions 18b, 18c, and these engaging portions 9a, 9b, 9c are inserted into the engaged portions 18a, Click and engage with 18b and 18c, respectively. In this case, the engaging claw 11 provided in the upper engaging portion 9a is deformed by the elastic deformation of the entire cover member 6 (particularly, the portion of the annular frame portion 7) as shown in FIG. The front end 12a of the pair of positioning ribs 12 provided in the engaging portion 9a is brought into contact with the surface side of the upper end edge α of the opening 20 while being click-engaged with the back surface side of the upper end edge α. . Then, the engagement surface 11a of the engagement claw 11 is brought into a state of being in surface contact with the upper end edge α of the opening 20 in parallel with the opening 20 as shown in FIG. As shown in FIG. 12, the pair of positioning ribs 12 is in sliding contact with the pair of positioning ribs 25 of the engaged portion 18a and is sandwiched therebetween. On the other hand, the engaging claws 16 provided in the two engaging portions 9b and 9c on the lower side of the cover member 6 are engaged by the elasticity of the base portion of the holding piece β where the engaging claws 16 are formed. The mating portions 18b and 18c are smoothly click-engaged with the engaged pieces 22 with a relatively weak insertion force.

  When the cover member 6 is attached to the opening 3 of the front bumper 2 in this manner, the upper end edge α of the opening 20 is sandwiched between the engaging claw 11 and the pair of positioning ribs 12. (See FIG. 11). As a result, the position of the engaging portion 9a of the cover member 6 is restricted in the vehicle longitudinal direction. In addition, the pair of positioning ribs 12 of the engaging portion 9a of the cover member 6 is sandwiched and positioned between the pair of positioning ribs 25 of the engaged portion 18a (see FIG. 12), whereby the cover member 6 The position of the engaging portion 9a in the vehicle width direction is restricted.

  According to the cover member mounting structure having such a structure, the slits for imparting elasticity are formed in the projecting pieces 10 constituting the upper engaging portions 9a of the plurality of engaging portions 9a, 9b, 9c of the cover member 6. Without being provided, the rigidity of the holding portion of the engaging claw 11 is increased, and the engaging claw 11 is covered by the elastic deformation of the entire cover member 6 (that is, the bending of the cover member 6 itself). Since the upper end edge α of the opening 20 as the engaging portion 18a is click-engaged, the cover member 6 is engaged with the front bumper 2 with a sufficient engaging force after the cover member 6 is assembled. The engaging claw 11 is unlikely to come off from the upper end edge α of the opening 20, and therefore the cover member can be prevented from falling off from the front bumper 2. Moreover, in the present embodiment, a pair of positioning ribs 12 are provided on the engaging portion 9a of the cover member 6 and reinforcing ribs 13 are provided at positions corresponding to these ribs 12 to increase the rigidity of the engaging portion 9a. Further, as described above, the engaging surface 11a of the engaging claw 11 is click-engaged in a surface contact state with the upper end edge α, so that the engaging portion 9a of the cover member 6 is covered with the corresponding cover. It can be made more difficult to disengage from the engaging portion 18a. On the other hand, the engaging portions 9b and 9c other than the above-described engaging portion 9a are provided with a slit 17 for imparting elasticity, and a partial elastic deflection of only the engaging portions 9b and 9c is used to cover the front bumper 2. Since the click engagement with the engagement portions 18b and 18c is performed, the click engagement operation can be easily and smoothly performed with a relatively weak insertion force as in the conventional case.

  In the present embodiment, the guide rib 24 having the inclined guide surface 23 is provided at the upper end edge α of the opening 20 which is the engaged portion 18a of the front bumper 2 so that the cover member 6 is assembled. Since the engaging claw 11 is guided downward by the guiding action of the guide rib 24, the tip of the engaging claw 11 is brought to the upper edge α of the opening 20 when the cover member 6 is assembled. Therefore, the assembly workability of the cover member 6 can be improved.

  Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various modifications and changes can be made based on the technical idea of the present invention. For example, in the above-described embodiment, the engaging portion 9a provided at the upper end of the cover member 6 is an engaging portion that utilizes the elastic deformation of the entire cover member. It is also possible to provide at the lower end instead of the upper end. Further, when the cover member 6 has a vertical crosspiece, such an engaging portion can be provided at one side end of the cover member. In the embodiment described above, the two engaging portions 9b and 9c are provided as engaging portions other than the engaging portion 9a. However, three or more engaging portions (engagement portions having a conventional structure) are provided. May be provided. Further, the present invention can be applied not only to the front bumper 2 but also to the rear bumper.
