Description

[Technical field]

[0001] The present invention relates to a reinforcing member and a reinforcing structure for reinforcing the mechanical strength of an exterior part for a vehicle. [Background technology]

[0002] Vehicle exterior parts attached to a vehicle may have slits (notches) for various reasons. For example, in the case of a vehicle bumper made of resin, the bumper may be deformed when it is pulled out from a mold used for resin molding, so slits are formed at predetermined positions to facilitate this deformation.

[0003] In addition, in the case of a vehicle exterior part composed of multiple members, a slit may be required to connect the members. For example, when a connecting member is used to connect multiple members to each other, a slit may be formed in each member to attach the connecting member. In addition, in Patent Document 1 (JP Patent Publication 2003-312298), a slit-shaped notch groove is formed in the front bumper to connect the front bumper and the front fender.

[0004] [Patent Document 1] JP 2003-312298 A Summary of the Invention [Problem to be solved by the invention]

[0005] As described above, slits are formed in vehicle exterior parts for various reasons, but the presence of these slits can weaken the mechanical strength of the vehicle exterior part. That is, the vehicle exterior part is prone to deformation in the part where the slits are provided, such that the slits spread outward, which causes the mechanical strength of the vehicle exterior part to be weakened.

[0006] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide a reinforcing member and a reinforcing structure that can effectively increase the mechanical strength of a vehicle exterior part having a slit formed therein with a simple configuration. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention adopts the following solution: That is, as described in claim 1, a reinforcing member that is attached to a vehicle exterior part having a slit and reinforces the vicinity of the slit of the vehicle exterior part includes a support part that is disposed within the slit and a holding part that is provided at a predetermined interval from both sides in the width direction of the support part, and the held parts that are provided on both sides in the width direction of the slit are held by the holding parts.

[0008] According to the above solution, the retaining portion (e.g., first retaining wall portion 37, second retaining wall portion 38, fitting hole 53) of the reinforcing member (e.g., reinforcing members 30, 50) retains the retained portions (e.g., first protrusions 23A, 23B, second protrusions 24A, 24B, protrusion portion 56) provided on both sides of the slit (e.g., slits 21A, 21B, 55) of the vehicle exterior part (e.g., bumper 10, 54), so deformation of the slit of the vehicle exterior part such that it is pushed open is appropriately restricted, and the mechanical strength of the vehicle exterior part is increased.

[0009] A preferred embodiment based on the above-mentioned solution is as described in claim 2 and subsequent claims. That is, the held portion may be a protrusion provided on the vehicle exterior part and extending in the longitudinal direction from both widthwise sides of the slit, and the holding portion may be a fitting recess provided on the reinforcing member into which the protrusion fits (corresponding to claim 2). In this case, the protrusions (e.g., first protrusions 23A, 23B, second protrusions 24A, 24B) which are the held parts of the vehicle exterior part are fitted into the fitting recesses (e.g., first fitting recess 39, second fitting recess 40) formed by the holding parts (e.g., first holding wall 37, second holding wall 38) of the reinforcing member (e.g., reinforcing member 30) and are held by the holding parts from the opposite side to the support part (e.g., support part 35) (i.e., the opposite side to the slit), so that the holding by the holding parts is firm, and deformation of the slits (e.g., slits 21A, 21B) that would otherwise spread outward is effectively restricted, and the mechanical strength of the vehicle exterior part is significantly increased. In addition, the protrusions can be formed by extending both side portions of the opening ends of the slits (e.g., opening ends 22A, 22B), so that there is no need to add a new configuration, and the reinforcing structure can be simplified.

[0010] The vehicle exterior part is configured by connecting a plurality of exterior members at connecting parts provided on each of the exterior members, the connecting parts of the plurality of exterior members have the slits and the held parts at positions aligned with each other, the support parts of the reinforcing member are disposed in the slits of the plurality of exterior members, the holding parts of the reinforcing member hold the held parts of the plurality of exterior members from the side opposite to the slits, and the reinforcing member may have a clamping part that clamps the connecting parts of the plurality of exterior members together to connect the plurality of exterior members (corresponding to claim 3). In this case, the reinforcing member functions as a reinforcing member that prevents deformation that widens the slits for all of the plurality of exterior members (e.g., upper bumper member 10A, lower bumper member 10B) that constitute the vehicle exterior part, and also functions as a connecting member that clamps and connects the connecting parts (e.g., connecting parts 20A, 20B) of the plurality of exterior members with clamping parts (e.g., first clamping wall part 32, second clamping wall part 33). Therefore, one reinforcing member can have two functions, which makes it possible to simplify the configuration and reduce costs by reducing the number of parts.

[0011] Furthermore, as described in claim 4, in a reinforcing structure in which a vehicle exterior part having a slit is reinforced with a reinforcing member, the vehicle exterior part has a held portion provided on both widthwise sides of the slit, and the reinforcing member has a support portion disposed within the slit and a holding portion provided at a predetermined distance from both widthwise sides of the support portion, and the held portion is held by the holding portion.

[0012] According to the above solution, the retaining portion (e.g., first retaining wall portion 37, second retaining wall portion 38, fitting hole 53) of the reinforcing member (e.g., reinforcing members 30, 50) retains the retained portions (e.g., first protrusions 23A, 23B, second protrusions 24A, 24B, protrusion portion 56) provided on both sides of the slit (e.g., slits 21A, 21B, 55) of the vehicle exterior part (e.g., bumper 10, 54), so deformation of the slit of the vehicle exterior part such that it is pushed open is appropriately restricted, and the mechanical strength of the vehicle exterior part is increased.

[0013] A preferred embodiment based on the above-mentioned solution is as described in claim 5 and onwards in the claims. That is, the vehicle exterior part has a bent part that is arranged at a corner of the vehicle, and the slit may be formed in the bent part (corresponding to claim 5). In this case, since the slit is formed in the bent part of the vehicle exterior part, when the vehicle exterior part is manufactured, the vehicle exterior part can be easily deformed and easily pulled out from the molding die, while when the vehicle exterior part is used, deformation in the slit part is appropriately prevented by the reinforcing member. Effect of the Invention

[0014] According to the present invention, the retaining portions on both sides of the slit in the vehicle exterior part are retained by the retaining portion of the reinforcing member, thereby appropriately restricting deformation that would cause the slit to widen outward, and effectively increasing the mechanical strength of the vehicle exterior part.

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. Fig. 1 shows a vehicle 1 equipped with a vehicle bumper 10 to which the present invention is applied. The bumper 10 is an exterior vehicle component formed, for example, by resin molding, and is attached to the front of the vehicle 1 and disposed below a front grille 2 as shown in the drawing.

[0017] The bumper 10 has a front portion 11 that is disposed along the front surface 3 of the vehicle 1, and two side portions 12 that are disposed along the front end portions of both side surfaces 4 of the vehicle 1 (only the left side portion 12 of the vehicle 1 is shown in FIG. 1). A bent portion 13 that is curved at approximately 90 degrees is formed between the front portion 11 and the two side portions 12, and is arranged to be disposed at the corners 5 at both ends in the width direction of the front surface 3 of the vehicle 1. The reinforcing structure of the present invention is applied to this bent portion 13.

[0018] 2 is a schematic diagram for explaining the reason why slits are provided in the bumper 10. The bumper 10 of this embodiment is formed by resin molding, and therefore needs to be pulled out from the mold after molding. The figure shows a case where a mold 5 is placed inside the bumper 10, and the bumper 10 is pulled out from this mold 5.

[0019] In this case, bumper 10 is pulled out from mold 5 by moving it towards front portion 11 (left side in the figure), but because hook portion 14 bent inward is provided at the end of side portion 12 opposite front portion 11, hook portion 14 gets caught on mold 5. For this reason, when bumper 10 is pulled out from mold 5, side portion 12 is bent outward as shown by the dashed dotted line in the figure to deform bumper 10, thereby avoiding interference between hook portion 14 and mold 5. To facilitate such deformation of bumper 10, slit 21 is provided on the inside portion of bent portion 13.

[0020] Fig. 3 shows an outline of the reinforcement structure in an embodiment of the present invention. Note that this figure shows a state before the reinforcement member 30 is attached to the bumper 10, and also shows only a part of the bumper 10 in a cutaway state.

[0021] As shown in the figure, the bumper 10 is configured by combining an upper bumper member 10A and a lower bumper member 10B one above the other. In the following description, the reference numerals of the corresponding components of the upper bumper member 10A and the lower bumper member 10B are the same, but the components of the upper bumper member 10A are marked with A, and the components of the lower bumper member 10B are marked with B.

[0022] The bent portion 13A of the upper bumper member 10A and the bent portion 13B (not shown) of the lower bumper member 10B are provided with connecting portions 20A and 20B, respectively, which are shaped like eaves and extend horizontally inside the curve. The connecting portions 20A and 20B are plate-like portions having the same shape and are stacked on top of each other. As will be described in detail later, the upper bumper member 10A and the lower bumper member 10B are connected to each other at the connecting portions 20A and 20B.

[0023] The connecting portions 20A and 20B are formed with slits 21A and 21B, respectively. The slits 21A and 21B have the same shape and are formed at positions that match each other, and are stacked vertically to form a single slit. As will be described in detail later, a reinforcing member 30 is attached to these slits 21A and 21B.

[0024] The slits 21A, 21B have opening ends 22A, 22B that open toward the inside of the bumper 10 (the inside of the vehicle 1). First protrusions 23A, 23B and second protrusions 24A, 24B are provided on the left and right sides of the opening ends 22A, 22B, respectively.

[0025] The first protrusions 23A, 23B and the second protrusions 24A, 24B are plate-like portions extending from both side portions of the opening ends 22A, 22B, and extend horizontally toward the inside of the bumper 10 (i.e., toward the inside of the vehicle 1). In this embodiment, the protrusions 24A, 24B are shaped to extend farther from the opening ends 22A, 22B than the protrusions 23A, 23B, and are also larger in size.

[0026] Locking holes 25A, 25B are formed in the connecting parts 20A, 20B so as to be located rearward of the protruding parts 24A, 24B (locking hole 25B is not shown). Locking hole 25A is formed in the upper surface of connecting part 20A and opens upward. On the other hand, locking hole 25B is formed in the lower surface of connecting part 20B and opens downward.

[0027] 4 to 7 show the details of the reinforcing member 30. In the following description, each component of the reinforcing member 30 is described using expressions indicating directions such as front-back, up-down, left-right, etc., but this is for convenience of description and does not limit the content of the present invention.

[0028] The reinforcing member 30 is a clip member made of, for example, resin. As shown in the figure, a first clamping wall portion 32 and a second clamping wall portion 33 are provided on both the upper and lower sides of a front end 31 side of the reinforcing member 30. The first clamping wall portion 32 and the second clamping wall portion 33 extend to near the center of the longitudinal direction (front-rear direction) of the reinforcing member 30 and are arranged parallel to each other with a predetermined interval between them.

[0029] A plurality of protrusions 34 extending in the longitudinal direction of the reinforcing member 30 are formed on the inward surfaces (opposing surfaces) of the first and second sandwiching wall portions 32, 33. As a result, when the reinforcing member 30 is attached to the bumper 10, the connecting portions 20A, 20B of the bumper 10 are sandwiched from above and below between the first sandwiching wall portion 32 and the second sandwiching wall portion 33 and are held in contact with the protrusions 34.

[0030] A support column 35 is provided between the first sandwiching wall 32 and the second sandwiching wall 33. The support column 35 is a plate-shaped portion extending from the inward surface of the first sandwiching wall 32 to the inward surface of the second sandwiching wall 33, and extends from near the front end 31 of the reinforcing member 30 in the longitudinal direction of the reinforcing member 30. The support column 35 is a portion that is disposed within the slits 21A and 21B when the reinforcing member 30 is attached to the bumper 10, and its left-right width is set to be slightly smaller than the width of the slits 21A and 21B of the bumper 10.

[0031] A first retaining wall portion 37 and a second retaining wall portion 38 are provided on the rear end 36 side of the reinforcing member 30. The first and second retaining wall portions 37, 38 form part of the outer wall extending from the left and right sides of the reinforcing member 30 to the rear end 36. The first retaining wall portion 37 is continuous with the rear ends of the side surfaces of the first and second sandwiching walls 32, 33.

[0032] The first and second retaining walls 37, 38 are disposed on both the left and right sides of the support pillar 35. As a result, a first fitting recess 39 into which the first protrusions 23A, 23B of the bumper 10 fit is formed on the inner side (support pillar 35 side) of the first retaining wall 37, and a second fitting recess 40 into which the second protrusions 24A, 24B of the bumper 10 fit is formed on the inner side (support pillar 35 side) of the second retaining wall 38.

[0033] The first retaining wall 37 and the second retaining wall 38 have retaining projections 41 and 42 formed on their inward surfaces, respectively, which protrude toward the support 35. When the first protrusions 23A, 23B and the second protrusions 24A, 24B of the bumper 10 are fitted into the first fitting recess 39 and the second fitting recess 40, the retaining projections 41 and 42 come into contact with the first protrusions 23A, 23B and the second protrusions 24A, 24B, respectively, from the side opposite the support 35. As a result, the first protrusions 23A, 23B and the second protrusions 24A, 24B are retained by the first retaining wall 37 and the second retaining wall 38 from the side opposite the support 35 (i.e., the slits 21A, 21B).

[0034] The first and second fitting recesses 39, 40 have positions and shapes corresponding to the positions and shapes (dimensions) of the first protrusions 23A, 23B and the second protrusions 24A, 24B, respectively. To explain in detail, the first holding wall 37 is disposed near the center in the longitudinal direction of the reinforcing member 30, whereas the second holding wall 38 is disposed on the rear end 36 side of the reinforcing member 30. In addition, the support pillar 35 is disposed at a position where the distance between the support pillar 35 and the first holding wall 37 is narrower than the distance between the support pillar 35 and the second holding wall 38.

[0035] As a result, the first fitting recess 39 is formed between the support 35 and the first retaining wall 37 near the longitudinal center of the reinforcing member 30 in correspondence with the positions of the first protrusions 23A, 23B, and has a small dimension corresponding to the size of the first protrusions 23A, 23B. On the other hand, the second fitting recess 40 is formed between the inner wall surface 43 at the rear of the support 35 and the second retaining wall 38 near the rear end 31 of the reinforcing member 30 in correspondence with the positions of the second protrusions 24A, 24B, and has a large dimension corresponding to the size of the second protrusions 24A, 24B.

[0036] Upper and lower locking arms 44 are provided at the rear ends of the first and second sandwiching walls 32, 33, respectively. The locking arms 44 are provided on the second holding wall 38 side (in front of the fitting recess 40) with respect to the support 35, and include an engagement claw 45 on the tip side, an operation portion 46 on the base end side, and a connection portion 47 provided between the engagement claw 45 and the operation portion 46. The locking arms 44 are formed integrally with the first and second sandwiching walls 32, 33 via the connection portion 47.

[0037] When the reinforcing member 30 is attached to the bumper 10, the engaging claws 45 of the locking arms 44 engage with the locking holes 25A, 25B of the bumper 10. This causes the reinforcing member 30 to be locked to the bumper 10 (connecting portions 20A, 20B) and prevents the reinforcing member 30 from falling off the bumper 10.

[0038] By operating the operating portion 46 protruding outward from the reinforcing member 30 inward, the locking arm 44 can be rotated in a direction in which the locking claws 45 are disengaged from the locking holes 25A, 25B, and this operation allows the engagement claws 45 to engage with and disengage from the locking holes 25A, 25B.

[0039] 8 and 9 show the reinforcing member 30 attached to the bumper 10. When attaching the reinforcing member 30 to the bumper 10, the front end 31 of the reinforcing member 30 is directed toward the bumper 10 (the state shown in FIG. 3), and then the support pillars 35 of the reinforcing member 30 are inserted into the slits 21A, 21B from the opening ends 22A, 22B of the slits 21A, 21B.

[0040] When the reinforcing member 30 is attached to the bumper 10, as shown in FIG. 8, the support portion 35 of the reinforcing member 30 is disposed in the slits 21A and 21B, and the first and second clamping wall portions 32 and 33 of the reinforcing member 30 are disposed above and below the connecting portions 20A and 20B of the bumper 10. As a result, the protrusions 34 of the reinforcing member 30 come into contact with the connecting portions 20A and 20B, and the connecting portions 20A and 20B are clamped from above and below by the first and second clamping wall portions 32 and 33. Therefore, the upper bumper member 10A and the lower bumper member 10B are connected by the reinforcing member 30 at the connecting portions 20A and 20B. That is, the reinforcing member 30 of this embodiment also functions as a connecting member that connects the upper bumper member 10A and the lower bumper member 10B.

[0041] 9, the first protrusions 23A, 23B and the second protrusions 24A, 24B of the bumper 10 are fitted into the first fitting recess 39 and the second fitting recess 40, respectively. As a result, the first protrusions 23A, 23B and the second protrusions 24A, 24B come into contact with the holding protrusions 41, 42 of the first and second holding walls 37, 38, and are held from the opposite side to the slits 21A, 21B. This appropriately restricts the deformation of the slits 21A, 21B of the bumper 10 from expanding outward, and increases the mechanical strength of the bumper 10.

[0042] As described above, according to the reinforcing member 30 and the reinforcing structure of this embodiment, the first and second holding walls 37 and 38 on both sides hold the first and second protrusions 23A and 23B, 24A and 24B provided on both sides of the slits 21A and 21B from the side opposite the slits 21A and 21B, so that the deformation of the slits 21A and 21B expanding outward is appropriately restricted. Therefore, the mechanical strength of the bumper 10 is improved simply by attaching the reinforcing member 30 to the slits 21A and 21B. In addition, the reinforcing member 30 can be easily attached by simply inserting the support 35 into the slits 21A and 21B. In addition, the first and second protrusions 23A and 23B, 24A and 24B are formed by extending both side portions of the opening ends 22A and 22B of the slits 21A and 21B, so that it is not necessary to add a new configuration as a held portion held by the first and second holding walls 37 and 38.

[0043] In addition, since the support pillars 35 are disposed in the slits 21A, 21B, it is possible to appropriately position the reinforcing member 30 with respect to the bumper 10. In addition, since the support pillars 35 restrict the inward deformation of the slits 21A, 21B, the deformation of the slits 21A, 21B is appropriately prevented.

[0044] Furthermore, since connecting portion 20A of upper bumper member 10A and connecting portion 20B of lower bumper member 10B are sandwiched by first and second sandwiching walls 32, 33 of reinforcing member 30 while overlapping each other, upper bumper member 10A and lower bumper member 10B are connected by reinforcing member 30 at connecting portions 20A, 20B. Therefore, reinforcing member 30 also functions as a connecting member, and there is no need to prepare a connecting member other than reinforcing member 30, so that the configuration of the vehicle exterior part can be simplified and costs can be reduced by reducing the number of parts.

[0045] In addition, the locking claws 45 of the locking arms 44 of the reinforcing member 30 engage with the locking holes 25A, 25B of the bumper 10 to lock the reinforcing member 30 to the bumper 10, thereby appropriately preventing the reinforcing member 30 from falling off. In addition, the locking arms 44 can be easily engaged with and disengaged from the locking holes 25A, 25B by simply pressing the operating portion 46.

[0046] 10 shows an outline of another embodiment of the present invention. As shown in the figure, a reinforcing member 50 of this embodiment includes a plate-shaped main body 51, a support portion 52 provided on the underside of the main body 51, and fitting holes 53 formed at predetermined positions on both sides of the support portion 52. Meanwhile, a bumper 54 includes a slit 55 and protrusions 56 provided at predetermined positions on both sides of the slit 55.

[0047] When the reinforcing member 50 is attached to the bumper 54, the support portion 52 is placed in the slit 55, and the protrusions 56 on both sides are fitted into the corresponding fitting holes 53. This allows both sides of the slit 55 to be held by the reinforcing member 50, and prevents the slit 55 from being pushed outward and thus increases the mechanical strength of the bumper 54.

[0048] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and appropriate modifications are possible within the scope of the claims. For example, in the above embodiment, the holding portion of the reinforcing member 30 is the first and second holding wall portions 37 and 38 that constitute a part of the outer wall of the reinforcing member 30, but the form of the holding portion in the present invention is not limited to this embodiment, and can take any form as long as it holds the held portions on both sides of the slit from the side opposite the slit.

[0049] In the embodiment shown in FIG. 10, a protrusion may be provided on the reinforcing member 50, and a fitting hole into which the protrusion fits may be provided on the bumper 54. [Industrial Applicability]

[0050] The present invention can be used to increase the mechanical strength of a vehicle bumper. [Explanation of symbols]
