Description

[Technical Field]

[0001] The present invention relates to a vehicle body structure. [Background technology]

[0002] Patent Document 1 listed below discloses an integrated energy absorption system having a front casting provided at the front end of a vehicle and a rear casting provided at the rear end of the vehicle. In this technology, the front casting and the rear casting are each integrally molded by die casting and fixed to the central cab frame. By integrally molding the front casting and the rear casting as in this technology, the number of parts and manufacturing costs can be reduced.

[0003] In the above technology, the front casting includes a pair of left and right wheel wells (wheel arches) and a lateral support body (cross member portion) that connects the pair of wheel arches in the vehicle width direction. In the above technology, the portion corresponding to the apron upper member of the wheel arch (hereinafter referred to as the "upper member portion") extends in the front-rear direction of the vehicle above and outside in the vehicle width direction of the portion corresponding to the suspension tower (hereinafter referred to as the "sus tower portion").

[0004] In the above technique, when forming a pair of left and right wheel arches, each mold is pulled outward in the vehicle width direction. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] International Publication No. 2022 / 031991 Summary of the Invention [Problem to be solved by the invention]

[0006] Incidentally, when using a strut-type suspension in which the spring is positioned above the tire, or when using a large suspension stroke, it is desirable to ensure that the vertical dimension of the accommodation space of the suspension tower is large. In other words, it is desirable to make the upper wall portion formed on the upper side of the suspension tower higher than the upper member portion.

[0007] However, when adopting the above structure, if the upper member portion is positioned on the vehicle width outside of the suspension tower portion, as in the prior art described above, the mold that forms the upper wall portion of the suspension tower portion interferes with the upper member portion when it is removed on the vehicle width outside, making it impossible to remove the mold.

[0008] Taking the above facts into consideration, the present invention aims to obtain a vehicle body structure in which a pair of wheel arches and a cross member can be molded integrally while ensuring a large vertical dimension of the storage space for the suspension tower section at the front of the vehicle. [Means for solving the problem]

[0009] The vehicle body structure of the present invention described in claim 1 comprises a cross member portion extending in the vehicle width direction at the front of the vehicle, and a pair of left and right wheel arches provided on both sides of the cross member portion in the vehicle width direction and formed integrally with the cross member portion, wherein the pair of left and right wheel arches are configured to include a suspension tower portion extending in the vehicle fore-and-aft direction and in the vehicle width direction and having an upper wall portion to which a shock absorber is connected, and an apron upper member portion extending in the vehicle fore-and-aft direction and formed along the peripheral edge of the upper wall portion so that the portion formed along the suspension tower portion is lower than the upper wall portion and detours the shock absorber to the inside of the vehicle width direction in a plan view.

[0010] According to the present invention as set forth in claim 1, at the front of the vehicle, a cross member portion extending in the vehicle width direction is molded integrally with a pair of left and right wheel arches provided on both sides of the cross member portion in the vehicle width direction. The pair of left and right wheel arches are configured to include suspension tower portions (hereinafter referred to as "sus tower portions") and apron upper member portions (hereinafter referred to as "upper member portions").

[0011] The suspension tower has an upper wall portion that extends in the longitudinal direction and width direction of the vehicle and to which the shock absorber is connected. The portion of the upper member formed along the suspension tower is located at a height lower than the upper wall portion. Therefore, the upper wall portion of the suspension tower is positioned at a high position.

[0012] The portion of the upper member formed along the suspension tower is formed along the peripheral edge of the upper wall so as to bypass the shock absorber to the inside in the vehicle width direction in plan view. As a result, even if the portion of the upper member formed along the suspension tower is positioned at a height lower than the upper wall, when molding the wheel arch, the portion of the mold that forms the upper wall does not interfere with the upper member, and the mold can be pulled outward in the vehicle width direction.

[0013] In the vehicle body structure of the present invention described in claim 2, the suspension tower portion has a vertical wall portion extending from the peripheral end of the upper wall portion toward the lower side of the vehicle, at least a portion of which is positioned inside the shock absorber in the vehicle width direction, and the apron upper member portion has a lower rib extending from the vertical wall portion toward the outside in the vehicle width direction, facing the upper wall portion.

[0014] According to the present invention described in claim 2, the vertical wall portion has a shape in which at least a portion is disposed on the inner side of the shock absorber in the vehicle width direction, and can be formed together with the upper wall portion by a die that punches outward in the vehicle width direction. Here, the portion surrounded by the upper wall portion and vertical wall portion of the suspension tower portion and the lower rib of the upper member portion forms a recess that has a substantially U-shaped cross section and is open outward in the vehicle width direction. Therefore, the recess including the lower rib can be formed by a die that punches outward in the vehicle width direction.

[0015] The vehicle body structure of the present invention described in claim 3 is the invention described in claim 1, wherein the suspension tower portion has a vertical wall portion extending in the vertical direction of the vehicle and at least a portion of which is positioned inside the shock absorber in the vehicle width direction, and the apron upper member portion has an outer wall portion extending from the peripheral end of the upper wall portion toward the lower side of the vehicle, an inner wall portion formed opposite the outer wall portion at the upper end of the vertical wall portion, and a bottom portion connecting the lower end of the outer wall portion and the lower end of the inner wall portion.

[0016] According to the present invention as set forth in claim 3, a recess is formed that is surrounded by the outer wall and bottom of the apron upper member and the inner wall formed at the upper end of the upper member. Therefore, the wheel arch has the outer wall and bottom of the apron upper member in addition to the upper wall and vertical wall of the suspension tower, and the outer wall and bottom are perpendicular to each other, so the rigidity of the apron upper member is improved compared to when the apron upper member is formed only by ribs extending in one direction.

[0017] The vehicle body structure of the present invention described in claim 4 is the invention described in claim 3, wherein the apron upper member portions each extend in the vertical direction of the vehicle to connect the outer wall portion, the inner wall portion and the bottom portion, and are provided with a plurality of reinforcing ribs spaced apart from each other.

[0018] According to the present invention as set forth in claim 4, the recess surrounded by the inner wall portion, the bottom portion, and the outer wall portion is reinforced by a plurality of reinforcing ribs provided at intervals from one another to prevent the recess from collapsing. This improves the rigidity of the apron upper member. Furthermore, the recess is formed with a generally U-shaped cross section that opens toward the upper side of the vehicle. Therefore, the plurality of reinforcing ribs can also be molded using a mold that is pulled toward the upper side of the vehicle when molding the recessed surface of the recess.

[0019] The vehicle body structure of the present invention described in claim 5 is the invention described in claim 1, in which a pair of left and right front side member portions extending in the fore-and-aft direction of the vehicle are arranged on the vehicle lower side and inward in the vehicle width direction of the suspension tower portions of the pair of left and right wheel arches, and the front side member portions are molded integrally with the pair of left and right wheel arches.

[0020] According to the present invention as set forth in claim 5, not only the cross member portion and the pair of left and right wheel arches but also the pair of left and right front side member portions are integrally molded, thereby making it possible to reduce the number of parts and manufacturing processes. [Effects of the Invention]

[0021] As described above, the vehicle body structure of the present invention described in claim 1 has the excellent effect of being able to integrally mold a pair of wheel arches and a cross member while ensuring a large vertical dimension of the storage space for the suspension tower section at the front of the vehicle.

[0022] The vehicle body structure according to the present invention as set forth in claim 2 has the excellent effect of being able to configure the apron upper member of the vehicle with a simple structure and improve its rigidity.

[0023] The vehicle body structure according to the present invention as set forth in claim 3 has the excellent effect of improving the rigidity of the apron upper member portion.

[0024] The vehicle body structure according to the present invention as set forth in claim 4 has the excellent effect of improving the rigidity of the apron upper member portion while allowing it to be easily molded.

[0025] The vehicle body structure according to the present invention as set forth in claim 5 has the excellent effect of reducing the number of parts and manufacturing steps. [Brief explanation of the drawings]

[Figure 6] FIG. 6 is a cross-sectional view taken along line 6-6 in FIG. 5. DETAILED DESCRIPTION OF THE INVENTION

[0027] A vehicle body to which a vehicle body structure according to one embodiment of the present invention is applied will be described below with reference to Figures 1 to 4. Note that the arrows FR, UP, and RH shown as appropriate in each figure indicate the front side, upper side, and right side in the left-right direction (width direction) of the vehicle, respectively. Furthermore, when the front-rear, up-down, and left-right directions are used in the following description unless otherwise specified, they refer to front-rear in the front-rear direction of the vehicle, up-down in the up-down direction of the vehicle, and left-right in the left-right direction (width direction), respectively.

[0028] 1 shows a vehicle body 14 of a vehicle 12 to which the vehicle body structure according to this embodiment is applied. The vehicle body 14 includes a front body 16 constituting the front portion of the vehicle, a center body 18 constituting the central portion of the vehicle in the fore-and-aft direction, and a rear body 20 constituting the rear portion of the vehicle.

[0029] The front body 16 includes a front casting 22 that is integrally molded by, for example, aluminum die casting. The front casting 22 includes a cross member portion 24 that extends in the vehicle width direction on the vehicle front side of the center body 18, and a pair of left and right wheel arches 26 that are provided on both sides of the cross member portion 24 in the vehicle width direction. Note that because the front casting 22 is configured symmetrically, the following description will mainly focus on the configuration of the right side, and description of the configuration of the left side will be omitted.

[0030] The wheel arch 26 is configured to be able to accommodate, on the outer side in the vehicle width direction, a wheel (not shown) and a shock absorber 28 (see FIG. 3) to which a spring (not shown) is attached.

[0031] The wheel arch 26 is provided with a suspension tower section 30 (hereinafter referred to as "sus tower section 30") to which a shock absorber 28 (see Figure 3) is connected. The sus tower section 30 is formed in a box shape that is open on the outer side in the vehicle width direction and on the lower side of the vehicle. Details of the sus tower section 30 will be described later using Figure 2.

[0032] The wheel arch 26 includes a front side member portion 32 (referred to as "Fr side member portion 32") that extends substantially in the vehicle longitudinal direction below the suspension tower portion 30 and on the vehicle widthwise inner side. The Fr side member portion 32 forms the framework of the lower portion of the front body 16.

[0033] The wheel arch 26 also includes an apron upper member portion 34 (hereinafter referred to as the "upper member portion 34") that extends substantially in the vehicle longitudinal direction above the vehicle and on the outer side in the vehicle width direction of the front side member portion 32. The rear end of the upper member portion 34 is joined to a front pillar 36. The upper member portion 34 forms the framework of the upper lateral portions of the front body 16.

[0034] Crash boxes 38 extend in the vehicle front-rear direction on the vehicle front side of the front side member portion 32, and are capable of absorbing collision energy in the event of a frontal collision of the vehicle 12. Front ends of the left and right crash boxes 38 are connected in the vehicle width direction by a front bumper 40.

[0035] 2 is an enlarged rear perspective view of the area around the right-side suspension tower 30. The wheel arch 26 includes a wheel arch front portion 42 formed on the vehicle front side of the suspension tower 30, and a wheel arch rear portion 44 formed on the vehicle rear side of the suspension tower 30. A front flange portion 42A extending outward in the vehicle width direction is formed at the upper end of the wheel arch front portion 42. Similarly, a rear flange portion 44A extending outward in the vehicle width direction is formed at the upper end of the wheel arch rear portion 44.

[0036] The suspension tower 30 includes an upper wall 46 that extends substantially horizontally and to which the shock absorber 28 (see FIG. 3) is connected on the vehicle lower side, and a vertical wall 48 that extends from the peripheral edge of the upper wall 46 toward the vehicle lower side. The upper wall 46 is flush with the front flange 42A and the rear flange 44A.

[0037] As shown in FIG. 3 , the vertical wall portion 48 is formed in a generally U-shape in a planar cross-sectional view, opening outward in the vehicle width direction. The vertical wall portion 48 includes a front wall portion 48A extending generally in the vehicle width direction at the front side of the vehicle, a side wall portion 48B extending from the inner end of the front wall portion 48A toward the rear side of the vehicle, and a rear wall portion 48C extending from the rear end of the side wall portion 48B toward the outer side in the vehicle width direction. The shock absorber 28 is disposed between the front wall portion 48A and the rear wall portion 48C and on the outer side in the vehicle width direction of the side wall portion 48B. The front wall portion 48A and the rear wall portion 48C face each other and are spaced apart as they extend outward in the vehicle width direction. This allows the suspension tower portion 30 to be formed using a mold that is punched outward in the vehicle width direction.

[0038] 2, the upper member portion 34 includes a lower rib 50 formed along the wheel arch front portion 42, the vertical wall portion 48, and the wheel arch rear portion 44. The lower rib 50 extends outward in the vehicle width direction from the wheel arch front portion 42, the vertical wall portion 48, and the wheel arch rear portion 44, respectively.

[0039] The lower rib 50 includes a front portion 50A formed along the front portion 42 of the wheel arch, a middle portion 50B formed along the vertical wall portion 48 of the suspension tower portion 30, and a rear portion 50C formed along the rear portion 44 of the wheel arch.

[0040] The front portion 50A faces the front flange portion 42A and is formed on the vehicle lower side of the front flange portion 42A. Similarly, the rear portion 50C faces the rear flange portion 44A and is formed on the vehicle lower side of the rear flange portion 44A.

[0041] The middle portion 50B is formed opposite the upper wall portion 46 on the vehicle lower side of the upper wall portion 46. The middle portion 50B is formed along the front wall portion 48A, the side wall portion 48B, and the rear wall portion 48C, respectively, in a generally U-shape that opens outward in the vehicle width direction in plan view. The middle portion 50B is formed continuous with the front portion 50A and the rear portion 50C. In other words, as shown in FIG. 3 , the lower rib 50 is formed along the upper portion of the wheel arch front portion 42, the upper portion of the vertical wall portion 48 of the suspension tower portion 30, and the upper portion of the wheel arch rear portion 44 so as to bypass the shock absorber 28 toward the inside in the vehicle width direction in plan view.

[0042] 4, the front side member portion 32 is formed in a generally E-shape that is open outward in the vehicle width direction in a vertical cross section seen from the front side of the vehicle. Furthermore, the upper portion of the suspension tower portion 30 is formed in a generally U-shape that is open outward in the vehicle width direction by extending a lower rib 50 from the vertical wall portion 48. The portion surrounded by the upper wall portion 46, the side wall portion 48B, and the lower rib 50 forms a recess 52 that is generally U-shaped in cross section and open outward in the vehicle width direction.

[0043] (action) Next, the operation of this embodiment will be described.

[0044] According to the vehicle body structure of this embodiment, as shown in FIG. 1, in the front casting 22 of the front body 16 of the vehicle 12, a cross member portion 24 extending in the vehicle width direction is molded integrally with a pair of left and right wheel arches 26.

[0045] As shown in Figure 2, the suspension tower section 30 has an upper wall section 46 that extends in the vehicle longitudinal direction and the vehicle width direction and to which the shock absorber 28 (see Figure 3) is connected. In the upper member section 34, a middle section 50B formed along the suspension tower section 30 is located at a height equal to or lower than the upper wall section 46. Therefore, the upper wall section 46 of the suspension tower section 30 is located at a high position.

[0046] 3, the portion of the upper member portion 34 that is formed along the suspension tower portion 30 is formed along the peripheral edge of the upper wall portion 46 so as to bypass the shock absorber 28 toward the inside in the vehicle width direction in a plan view. As a result, even if the middle portion 50B of the upper member portion 34 is positioned at a height lower than the upper wall portion 46 as shown in Figures 2 and 4, when molding the wheel arch 26, the portion of the mold (not shown) that forms the upper wall portion 46 does not interfere with the upper member portion 34, and the mold can be pulled out toward the outside in the vehicle width direction.

[0047] Furthermore, according to the vehicle body structure of this embodiment, as shown in Fig. 3, the vertical wall portion 48 has a shape in which the side wall portion 48B is disposed on the inner side of the shock absorber 28 in the vehicle width direction, and can be formed together with the upper wall portion 46 shown in Fig. 4 using a mold that punches outward in the vehicle width direction. Here, the portion surrounded by the upper wall portion 46, the side wall portion 48B, and the lower rib 50 forms a recess 52 that has a generally U-shaped cross section and is open outward in the vehicle width direction. Therefore, the recess 52, including the lower rib 50, can be formed using a mold that punches outward in the vehicle width direction.

[0048] Furthermore, according to the vehicle body structure of this embodiment, as shown in Fig. 1, not only the cross member portion 24 and the pair of left and right wheel arches 26, but also the pair of left and right front side member portions 32 are integrally molded, which makes it possible to reduce the number of parts and manufacturing processes.

[0049] [Supplementary explanation of the above embodiment] In the above embodiment, the lower rib 50 constituting the upper member portion 34 is described as being provided facing the upper wall portion 46 and below the upper wall portion 46, but this is not limiting, and the upper member may be formed at a height equal to or lower than the upper wall portion. For example, a vehicle body structure according to the modified example shown in Figures 5 and 6 may be employed. Note that in the following modified examples, the same components as those in the above embodiment will be denoted by the same reference numerals and descriptions thereof will be omitted where appropriate.

[0050] (Variation) 5 shows an enlarged front perspective view of a main portion of a front casting 64 of a vehicle body 62 of a vehicle 60 equipped with a vehicle front structure according to a modified example. The front casting 64 includes a cross member portion 24 (see FIG. 1) extending in the vehicle width direction at the front of the vehicle, and wheel arches 66 provided on both sides of the cross member portion 24 in the vehicle width direction. The pair of wheel arches 66 are molded integrally with the cross member portion 24 (see FIG. 1).

[0051] As shown in Figure 5, the wheel arch 66 has a suspension tower portion 68 (hereinafter referred to as the "sus tower portion 68"), an apron upper member portion 70 (hereinafter referred to as the "upper member portion 70"), and a Fr side member portion 32.

[0052] The suspension tower 68 includes an upper wall 72 that extends substantially horizontally and to which the shock absorber 28 (see FIG. 3) is connected, and a vertical wall 48 that extends in the vertical direction of the vehicle. The upper wall 72 and the vertical wall 48 are connected by an upper member 70.

[0053] The upper member portion 70 is provided at a height equal to or lower than the upper wall portion 72, and includes a recessed portion 74 recessed toward the lower side of the vehicle, and a plurality of reinforcing ribs 76 provided at intervals in the recessed portion 74.

[0054] As shown in Figures 5 and 6, the recess 74 is composed of an outer wall portion 78 extending from the peripheral edge of the upper wall portion 72 toward the lower side of the vehicle, an inner wall portion 80 formed opposite the outer wall portion 78 at the upper end of the vertical wall portion 48, and a bottom portion 82 connecting the lower end of the outer wall portion 78 and the lower end of the inner wall portion 80.

[0055] The multiple reinforcing ribs 76 extend in the vehicle vertical direction in the recess 74, connecting the outer wall portion 78, the inner wall portion 80, and the bottom portion 82. The upper surfaces of the reinforcing ribs 76 are, for example, flush with the upper wall portion 72.

[0056] According to this modified example, a recess 74 is formed that is surrounded by an outer wall portion 78, a bottom portion 82, and an inner wall portion 80. Therefore, the wheel arch 66 has the outer wall portion 78 and the bottom portion 82 of the upper member portion 70 in addition to the upper wall portion 72 and the vertical wall portion 48 of the suspension tower portion 68, and the outer wall portion 78 and the bottom portion 82 are perpendicular to each other, so that the rigidity of the upper member portion 70 is improved compared to a configuration in which the upper member portion is formed only by ribs extending in one direction.

[0057] Furthermore, the recess 74 surrounded by the inner wall portion 80, the bottom portion 82, and the outer wall portion 78 is reinforced by a plurality of reinforcing ribs 76 provided at intervals from one another to prevent it from collapsing. This improves the rigidity of the upper member portion 70. The recess 74 is also formed with a generally U-shaped cross section that opens toward the upper side of the vehicle. Therefore, the plurality of reinforcing ribs 76 can also be molded using the same mold that is used to punch toward the upper side of the vehicle when molding the recessed surface of the recess 74.

[0058] In the above-described embodiment, a reinforcing rib may be provided on the vehicle upper side of the lower rib 50. In this case, the reinforcing rib is provided along the vehicle width direction so that the mold can be removed outward in the vehicle width direction. In this case, a plurality of reinforcing ribs may be provided as in the modified example. Also, the reinforcing rib 76 may not be formed in the recess 74 of the modified example.

[0059] Furthermore, although the front casting 22 in the above-described embodiment and the front casting 64 in the modified example have been described as being integrally molded by aluminum die-casting, this is not limitative. For example, the cross member portion and the pair of left and right wheel arches may be integrally molded from resin. In this case, as in the above-described embodiment and modified example, the pair of left and right front side members may also be integrally molded from resin.

[0060] Furthermore, in the above-described embodiment and modified examples, the pair of left and right Fr side member portions 32 are also described as being integrally molded, but this is not limited thereto, and the pair of left and right front side members may be molded separately from the pair of left and right wheel arches and cross member portions.
