FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] One embodiment of the present invention is characterized by comprising a center bumper located in the center of the front of the vehicle in the vehicle width direction, side bumpers adjacent to the outside of the center bumper in the vehicle width direction, a center bumper lower section adjacent to and below the center bumper, and a side bumper lower section adjacent to and below the side bumper.

[0010] According to the present invention, since the vehicle bumper is divided into four components, namely, the center bumper, the side bumper, the center bumper lower section, and the side bumper lower section, when the vehicle bumper is damaged, it is not necessary to replace the entire bumper, but each component can be replaced individually. This reduces repair costs. Furthermore, since the materials of each of the four components that make up the vehicle bumper can be freely selected, a vehicle bumper made up of the right components for the right job can be manufactured. Furthermore, since the four components can be individually painted and surface treated, the cumbersome process of masking required when painting an integrally molded bumper can be omitted.

[0011] A first parting line extending in the vehicle width direction is formed between the center bumper and the center bumper lower section and between the side bumper and the side bumper lower section, and a second parting line extending in the vertical direction is formed between the center bumper and the side bumper and between the center bumper lower section and the side bumper lower section, and the vehicle bumper may further include a side lower flange provided on the side bumper and extending downwardly beyond the first parting line with which the side bumper lower section overlaps from the front of the vehicle, a side inner flange provided on the side bumper and extending inward in the vehicle width direction beyond the second parting line with which the center bumper overlaps from the front of the vehicle, and a flange connecting portion provided on the side bumper and connecting the side lower flange and the side inner flange.

[0012] If there is a gap where the first and second parting marks intersect, there is a risk that the internal structure of the vehicle may be visible through this gap. However, with the above-described configuration, the flange connecting portion covers the gap, so the internal structure is hidden from the outside. In other words, a decrease in visibility can be prevented.

[0013] The vehicle bumper further includes a center lower flange provided on the center bumper and extending downwardly beyond the first parting line, a center lower outer flange provided on the center bumper lower and extending outward in the vehicle width direction beyond the second parting line, and a protrusion provided on the center lower flange and protruding outward in the vehicle width direction, the protrusion being positioned between the center lower outer flange and the flange connecting portion in the fore-and-aft direction.

[0014] According to the above configuration, since the protrusion is positioned between the center lower outer flange and the flange connecting portion, the protrusion further conceals the flange connecting portion that is hidden by the center lower outer flange, thereby further improving the appearance from the outside of the area where the first parting and second parting intersect.

[0015] The vehicle bumper may further include a convex portion that extends across both the center bumper and the center bumper lower section and protrudes toward the front of the vehicle in the vertical direction, and a back surface connecting portion that connects the back surfaces of the convex portion on the center bumper in the vehicle width direction.

[0016] According to the above configuration, since the convex portion protrudes forward in both the vertical direction, the vehicle bumper has increased rigidity against vertical stress. In addition, since the back surface connecting portion connects the back surfaces of the convex portions in the vehicle width direction, it is possible to prevent the convex portions from opening in the vehicle width direction.

[0017] The vehicle bumper may further include a first hole formed in the side inner flange of the side bumper, a first engagement claw extending from the center bumper and engaging with the first hole, a second hole formed in the center lower outer flange of the center bumper lower, and a second engagement claw extending from the side bumper lower and engaging with the second hole, and the first engagement claw and the second engagement claw may be positioned on opposite sides of the second border in the vehicle width direction.

[0018] According to the above configuration, the first engagement claw and the second engagement claw are disposed on opposite sides of the second parting line in the vehicle width direction. That is, the first engagement claw and the second engagement claw are not aligned in a direction along the second parting line, and the points where the first engagement claw engages with the first hole and the points where the second engagement claw engages with the second hole are prevented from becoming starting points for deformation of the vehicle bumper. [Example]

[0019] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Dimensions, materials, and other specific values ​​shown in these embodiments are merely examples for facilitating understanding of the invention and, unless otherwise specified, do not limit the present invention. In this specification and drawings, elements having substantially the same functions and configurations are designated by the same reference numerals to avoid redundant explanation, and elements not directly related to the present invention are not shown.

[0020] Fig. 1 is a front view of a vehicle bumper 100 according to an embodiment of the present invention. In Fig. 1 and all other drawings, the longitudinal direction of the vehicle is indicated by arrows F (Forward) and B (Backward), the left and right directions in the vehicle width direction are indicated by arrows L (Leftward) and R (Rightward), and the up and down directions are indicated by arrows U (Upward) and D (Downward).

[0021] As shown in FIG. 1, the vehicle bumper 100 includes a center bumper 102, side bumpers 104 on the outer sides of the center bumper 102 in the vehicle width direction, a center bumper lower part 106 below the center bumper 102, and a side bumper lower part 108 below the side bumper 104.

[0022] A first parting line P extending in the vehicle width direction is formed between the center bumper 102 and the center bumper lower section 106, and between the side bumper 104 and the side bumper lower section 108. The first parting line P is a boundary line formed by the overlapping of the lower end of the center bumper 102 and the upper end of the center bumper lower section 106, and a boundary line formed by the overlapping of the lower end of the side bumper 104 and the upper end of the side bumper lower section 108. The presence of the first parting line P and the absence of gaps between the edges maintains the parting line performance.

[0023] A second parting line Q extending in the vertical direction is formed between the center bumper 102 and the side bumper 104, and between the center bumper lower part 106 and the side bumper lower part 108. The second parting line Q is a boundary line formed by the overlapping lateral edges of the center bumper 102 and the side bumper 104, and a boundary line formed by the overlapping lateral edges of the center bumper lower part 106 and the side bumper lower part 108. The presence of the second parting line Q and the absence of gaps between the edges maintains parting performance.

[0024] The visibility performance means the ability to prevent the structure behind from being seen through the boundary (the boundary between components), that is, the appearance from the outside is good. Below, each component of the vehicle bumper 100 will be described in detail.

[0025] As shown in Fig. 1, the center bumper 102 is disposed at the center of the front part of the vehicle in the vehicle width direction. In this embodiment, the center bumper 102 is formed with a non-grained finish and a glossy finish. The center bumper 102 is made of polycarbonate.

[0026] FIG. 2(a) is an exploded front view of the vehicle bumper 100 of FIG. 1. FIG. 2(b) is a partially enlarged front view of the center bumper 102. FIG. 3 is an exploded perspective view of the vehicle bumper 100 of FIG. 1. As shown in FIG. 2(a), the center bumper 102 has a center bumper main portion 102A. An end portion 102A1 of the center bumper main portion 102A is curved toward the rear of the vehicle (in the direction from the front side to the back side of the paper surface of FIG. 2(a)). As shown in FIGS. 2 and 3, the center bumper main portion 102A has a convex portion 112.

[0027] The convex portion 112 protrudes toward the front of the vehicle in both the vertical direction. The convex portion 112 has a first plate portion 112a on the outer side in the vehicle width direction and a second plate portion 112b on the inner side in the vehicle width direction. The first plate portion 112a is inclined so that it is positioned further forward of the vehicle as it moves inward in the vehicle width direction. The second plate portion 112b is inclined so that it is positioned further forward of the vehicle as it moves outward in the vehicle width direction. The first plate portion 112a and the second plate portion 112b intersect and connect at the front of the vehicle, are open toward the rear of the vehicle, and are arranged in a V-shape in a plan view. The outer end of the first plate portion 112a of the convex portion 112 in the vehicle width direction forms a second parting line Q.

[0028] 2 and 3, the center bumper 102 has a center lower flange 113. The center lower flange 113 extends downward from the tip of the end 102A1 of the center bumper main portion 102A (in this embodiment, the lower end of the convex portion 112). The center lower flange 113 extends downward beyond the first parting line P. The center bumper lower member 106 overlaps with the center lower flange 113 from the front of the vehicle. The center lower flange 113 also has a protruding portion 113a that protrudes outward in the vehicle width direction, as shown in FIG. 2(b).

[0029] As shown in FIG. 1 , the side bumper 104 is adjacent to the center bumper 102 on the outer side in the vehicle width direction. The side bumper 104 has higher rigidity than the center bumper 102. In this embodiment, the side bumper 104 has no grain and is painted in the vehicle body color. Furthermore, polypropylene is used as the material for the side bumper 104. Therefore, the side bumper 104 is different from the center bumper 102 in terms of material and surface treatment.

[0030] As shown in Fig. 2, the side bumper 104 has a side bumper main portion 104A. An end portion 104A1 of the side bumper main portion 104A is curved toward the rear of the vehicle (in the direction from the front side to the back side of the paper in Fig. 2).

[0031] The side bumper 104 has a side inner flange 104a. The side inner flange 104a extends inward in the vehicle width direction from a tip of an inner end 104A1 of the side bumper main portion 104A in the vehicle width direction. The side inner flange 104a extends inward in the vehicle width direction beyond the second parting line Q. A lateral end 102A1, which is a lateral end of the center bumper 102, overlaps the side inner flange 104a from the front of the vehicle.

[0032] The side bumper 104 has a side lower flange 104b. The side lower flange 104b extends downward from the tip of a lower end 104A1 of the side bumper main portion 104A. The side lower flange 104b extends downward beyond the first parting line P. The upper end of the side bumper lower section 108 overlaps with the side lower flange 104b from the front of the vehicle.

[0033] The side bumper 104 has a flange connecting portion 104c. The flange connecting portion 104c connects the side inner flange 104a and the side lower flange 104b on the inner side of the second parting line Q in the vehicle width direction and below the first parting line P.

[0034] As shown in FIG. 1, the center bumper lower part 106 is adjacent to and below the center bumper 102, and extends to the undercover on the underside of the vehicle body. The center bumper lower part 106 has higher rigidity than the center bumper 102. In this embodiment, the center bumper lower part 106 is painted with a glossy black paint. Furthermore, polypropylene is used as the material for the center bumper lower part 106. Therefore, the material and surface treatment of the center bumper lower part 106 are different from those of the center bumper 102 described above.

[0035] The center bump lower portion 106 has a center bump lower portion main portion 106A. An outer end portion 106A1 of the center bump lower portion main portion 106A in the vehicle width direction is curved toward the rear of the vehicle (in the direction from the front side to the back side of the paper in FIG. 2). As shown in FIGS. 2 and 3, the center bump lower portion main portion 106A has a convex portion 116.

[0036] The convex portion 116 protrudes toward the front of the vehicle in both the vertical direction. The convex portion 116 has a third plate portion 116a on the outer side in the vehicle width direction and a fourth plate portion 116b on the inner side in the vehicle width direction. The third plate portion 116a is inclined so that it is positioned further forward of the vehicle as it moves inward in the vehicle width direction. The fourth plate portion 116b is inclined so that it is positioned further forward of the vehicle as it moves outward in the vehicle width direction. The third plate portion 116a and the fourth plate portion 116b intersect and connect at the front of the vehicle, are open toward the rear of the vehicle, and are arranged in a V shape in a plan view.

[0037] The convex portion 112 of the center bumper 102 and the convex portion 116 of the center bumper lower portion 106 are aligned so as to be continuous from top to bottom, so that the convex portion straddles both the center bumper 102 and the center bump lower portion 106 .

[0038] The center bumper lower section 106 has a center lower outer flange 117. The center lower outer flange 117 extends outward in the vehicle width direction from the tip of an end portion 106A1 of the center bumper lower main section 106A. The center lower outer flange 117 extends outward in the vehicle width direction beyond the second parting line Q. A lateral end portion 150 (see FIG. 2), which is an inner lateral end portion in the vehicle width direction of the side bumper lower section 108, overlaps the center lower outer flange 117 from the front of the vehicle.

[0039] As shown in FIG. 1 , the side bumper lower 108 is adjacent to and below the side bumper 104, and extends to the undercover. The side bumper lower 108 has higher rigidity than the center bumper 102. In this embodiment, the side bumper lower 108 is formed with a grained surface. Furthermore, polypropylene is used as the material for the side bumper lower 108. Therefore, the side bumper lower 108 is different from the center bumper 102 in terms of material and surface treatment. The side bumper lower 108 is made of the same material as the side bumper 104 and the center bumper lower 106, but has a different surface treatment.

[0040] An end 150 of the side bumper lower 108 is curved toward the rear of the vehicle (in the direction from the front to the back of the paper in FIG. 2). Also, unlike the above-mentioned members, the side bumper lower 108 does not have a flange used for connecting to the above-mentioned members.

[0041] An upper end 106A1 of the center bumper lower part 106 is located in front of the center lower flange 113 of the center bumper 102, and the boundary line formed by the center bumper lower part 106 and the center bumper 102 in a front view is part of the first parting line P. An upper end 150 of the side bumper lower part 108 is located in front of the side lower flange 104b of the side bumper 104, and the boundary line formed by the side bumper lower part 108 and the side bumper 104 in a front view is part of the first parting line P.

[0042] A lateral end portion 102A1 of the center bumper 102 is located in front of the side inner flange 104a of the side bumper 104, and the boundary line formed by the center bumper 102 and the side bumper 104 in a front view is part of the second parting line Q. In addition, a lateral end portion 150 of the side bumper lower portion 108 is located in front of the center lower outer flange 117 of the center bumper lower portion 106, and the boundary line formed by the side bumper lower portion 108 and the center bumper lower portion 106 in a front view is part of the second parting line Q.

[0043] 4 is a partially enlarged perspective view, seen from the front, of the combined center bumper 102 and side bumper 104 of the vehicle bumper 100 of FIG. 1. As shown in FIG. 4, a protrusion 113a is disposed on the front side of the flange connecting portion 104c. The flange connecting portion 104c conceals the structure at the rear of the vehicle. The protrusion 113a conceals a portion of the front surface of the flange connecting portion 104c.

[0044] 5 is a perspective view of the vehicle bumper 100 of FIG. 1, seen from the rear side. The flange connecting portion 104c bulges further rearward than the side inner flange 104a and the side lower flange 104b. The flange connecting portion 104c bulges further rearward than the protruding portion 113a of the center bumper 102.

[0045] Fig. 6 is a perspective view, seen from the front, of the center bumper lower 106 attached to the vehicle bumper 100 of Fig. 5. The protrusion 113a is located between the center lower outer flange 117 and the flange connecting portion 104c. The protrusion 113a is located forward of the flange connecting portion 104c, and the center lower outer flange 117 is located forward of the protrusion 113a. The protrusion 113a hides the flange connecting portion 104c, and the center lower outer flange 117 hides the protrusion 113a and the lower portions of the flange connecting portion 104c.

[0046] Fig. 7 is a front view showing the state in which the side bumper lower 108 is attached to the vehicle bumper 100 of Fig. 6. With this configuration, the center bumper 102, side bumper 104, center bumper lower 106, and the structure at the back between the side bumpers 104 are hidden by the flange connecting portion 104c. A portion of the flange connecting portion 104c is hidden by the protruding portion 113a.

[0047] 8 is a perspective view of the convex portion 112 of the vehicle bumper 100 of FIG. 1, viewed from the back side. The center bumper 102 has a back surface connecting portion 120. The back surface connecting portion 120 is provided at the lower part of the convex portion 112 and connects the back surfaces of the convex portion 112 in the vehicle width direction. The back surface connecting portion 120 is formed in a plate shape and is arranged so that the plate surface faces the up-down direction. In addition, the back surface connecting portion 120 extends further rearward than an imaginary plane that connects the rear end 112a1 of the first plate portion 112a and the rear end 112b1 of the second plate portion 112b.

[0048] The rear surface connecting portion 120 extends further toward the rear of the vehicle at the end 112b1 side than at the end 112a1 side. Note that the configuration of the present embodiment is not limited to the rear surface connecting portion 120, and the rear surface connecting portion 120 may have other shapes as long as it connects the first plate portion 112a and the second plate portion 112b. The angles of the lower portions of the first plate portion 112a and the second plate portion 112b are fixed by the rear surface connecting portion 120 and are difficult to change.

[0049] 9 is an exploded perspective view of the vehicle bumper 100 of FIG. 1, viewed from the rear side. The side bumper 104 has a first hole 104n in the side inner flange 104a. The center bumper 102 has a first engagement claw 112m that engages with the first hole 104n.

[0050] The center bumper lower 106 has a second hole 117n in the center lower outer flange 117. The side bumper lower 108 has a second engaging claw 108m that engages with the second hole 117n.

[0051] 10 is a rear view showing the positional relationship of the first engagement claw 112m, the second engagement claw 108m, and the second parting mark Q when the components of the vehicle bumper 100 in FIG. 9 are combined. The first engagement claw 112m is engaged with the first hole 104n on the inner side in the vehicle width direction. The second engagement claw 108m is engaged with the second hole 117n on the outer side in the vehicle width direction. With the first engagement claw 112m engaged with the first hole 104n and the second engagement claw 108m engaged with the second hole 117n, the first engagement claw 112m and the second engagement claw 108m are positioned opposite each other in the vehicle width direction with respect to the second parting mark Q.

[0052] Next, the assembly procedure for the vehicle bumper 100 will be described. The first engagement claw 112m of the center bumper 102 is engaged with the first hole 104n of the side bumper 104 from the front of the vehicle, and the center bumper 102 is connected to the side bumper 104. The third engagement claw 106m of the center bumper lower 106 is engaged with the third hole 102n of the center bumper 102 from the front of the vehicle, and the center bumper lower 106 is connected to the center bumper 102.

[0053] The second engagement claw 108m of the side bumper lower 108 is engaged with the second hole 117n of the center bumper lower 106 from the front of the vehicle, and the side bumper lower 108 is connected to the center bumper lower 106. At the same time, the fourth engagement claw 108p of the side bumper lower 108 is engaged with the fourth hole 104q of the center bumper 102 from the front of the vehicle, and the side bumper lower 108 is connected to the center bumper lower 106.

[0054] According to the configuration of this embodiment, as shown in FIG. 3, the vehicle bumper 100 is divided into four components: a center bumper 102, a side bumper 104, a center bumper lower part 106, and a side bumper lower part 108. Therefore, if the vehicle bumper 100 is damaged, it is not necessary to replace the entire bumper, but each component can be replaced individually. This reduces repair costs. Furthermore, since the materials of each of the four components constituting the vehicle bumper 100 can be freely selected, the vehicle bumper 100 can be manufactured using components that are optimally suited for each position. Furthermore, since the four components can be individually painted and surface-treated, the cumbersome process of masking, which is required when painting an integrally molded bumper, can be omitted.

[0055] Furthermore, because the vehicle bumper 100 is divided into four members, it is easy for workers to manage and transport each member. The lower portion of the vehicle bumper 100 can be made of shatter-resistant polypropylene, with the remaining members made of polycarbonate. Furthermore, the upper portion of the vehicle bumper 100 can be made of shatter-resistant polypropylene on the outer side in the vehicle width direction, with the remaining members made of polycarbonate.

[0056] As shown in Fig. 1, if there is a gap where the first parting line P and the second parting line Q intersect, there is a risk that the internal structure of the vehicle may be visible through this gap. However, according to this embodiment, as shown in Fig. 6, the flange connecting portion 104c covers the gap, so the internal structure is hidden from the outside. In other words, a decrease in visibility can be prevented.

[0057] Note that no flange is provided on the center bumper 102, but instead, a side inner flange 104a is provided on the side bumper 104. This is because the side bumper 104 has a wide portion that extends in the vehicle's fore-and-aft direction, and having a flange on the side bumper 104 makes it easier to absorb an impact applied from the front to the center bumper 102. Of the four members, the side bumper 104 is positioned furthest rearward on the vehicle, and is able to ultimately absorb impacts to other members.

[0058] According to this embodiment, as shown in Fig. 6, the protrusion 113a is disposed between the center lower outer flange 117 and the flange connecting portion 104c. Therefore, as shown in Fig. 7, the protrusion 113a further conceals the flange connecting portion 104c that is concealed by the center lower outer flange 117, thereby further improving the appearance from the outside of the area where the first parting edge P and the second parting edge Q intersect.

[0059] Furthermore, the protruding portion 113a has a line-forming side 113a1 (see FIG. 2(b)), which hides the flange connecting portion 104c, making the first parting line P look neat.

[0060] According to this embodiment, as shown in Fig. 3, the convex portions 112 protrude forward in both the vertical direction, which increases the rigidity of the vehicle bumper 100 against vertical stress. In addition, as shown in Fig. 8, the back surface connecting portions 120 connect the back surfaces of the convex portions 112 in the vehicle width direction, which also prevents the convex portions 112 from opening in the vehicle width direction.

[0061] Furthermore, the rear surface connecting portion 120 has a bead function and can suppress bending of the convex portion 112 in the vehicle width direction. The rear surface connecting portion 120 increases the rigidity of the center lower flange 113.

[0062] 10, the first engagement claw 112m and the second engagement claw 108m are disposed on opposite sides of the second parting line Q in the vehicle width direction. That is, the first engagement claw 112m and the second engagement claw 108m are not aligned in the direction along the second parting line Q, and the location where the first engagement claw 112m engages with the first hole 104n and the location where the second engagement claw 108m engages with the second hole 117n are prevented from becoming starting points for deformation of the vehicle bumper 100.

[0063] While the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to these examples. It is clear that those skilled in the art can conceive of various modifications and alterations within the scope of the claims, and it is understood that these modifications and alterations also fall within the technical scope of the present invention.
