Description

Technical Field

[0001] The present disclosure relates to a vehicle body structure. Background Art

[0002] In International Publication No. 2022 / 031991, an integrated energy absorption system is disclosed, which has 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 integrally formed by die casting respectively and are fixed to a central cab frame. As in this technology, by integrally forming the front casting and the rear casting respectively, the number of components and the manufacturing cost can be reduced.

[0003] In the above technology, the front casting is configured to include a pair of left and right wheel housings (wheel arches) and a lateral support (lateral member portion) connecting the pair of wheel arches in the vehicle width direction. In the above technology, a part of the baffle upper member corresponding to the wheel arch (hereinafter referred to as the "upper member portion") extends in the vehicle front-rear direction on the vehicle upper side and outside in the vehicle width direction of a portion corresponding to the suspension tower (hereinafter referred to as the "suspension tower portion").

[0004] In the above technology, when forming the pair of left and right wheel housings, the respective molds are pulled out toward the outside in the vehicle width direction.

[0005] In addition, in order to adopt a strut-type suspension in which a spring is arranged above a tire or to obtain a larger suspension stroke, it is desired to ensure a larger dimension in the vertical direction of the accommodation space of the suspension tower portion. That is, it is desired that an upper wall portion of the suspension tower portion formed on the vehicle upper side is higher than the upper member portion.

[0006] However, in the case of adopting the above structure, as in the above prior art, if the upper member portion is arranged outside in the vehicle width direction of the suspension tower portion, since the mold for forming the upper wall portion of the suspension tower portion will interfere with the upper member portion when being pulled out toward the outside in the vehicle width direction, the mold cannot be pulled out. Summary of the Invention

[0007] The present disclosure provides a vehicle body structure that can integrally form a pair of wheel housings and a lateral member while ensuring a larger dimension in the vertical direction of the accommodation space of the suspension tower portion at the front of the vehicle.

[0008] The body structure of the first aspect of the present disclosure has: a lateral member portion that extends in the vehicle width direction at the front of the vehicle; and a pair of left and right wheel arches that are provided on both sides in the vehicle width direction of the lateral member portion and are integrally formed with the lateral member portion. The pair of left and right wheel arches are configured to include: a suspension tower portion that has an upper wall portion that extends in the vehicle front-rear direction and the vehicle width direction and connects a shock absorber; and a baffle upper member portion that extends in the vehicle front-rear direction, and a portion formed along the suspension tower portion is at a height below the upper wall portion and is formed along the peripheral portion of the upper wall portion so as to bypass the shock absorber inward in the vehicle width direction when viewed from above.

[0009] According to the first aspect of the present disclosure, at the front of the vehicle, a lateral member portion that extends in the vehicle width direction and a pair of left and right wheel arches provided on both sides in the vehicle width direction of the lateral member portion are integrally formed. The pair of left and right wheel arches are configured to include a suspension tower portion and a baffle upper member portion (hereinafter referred to as the "upper member portion").

[0010] Here, the suspension tower portion has an upper wall portion that extends in the vehicle front-rear direction and the vehicle width direction and connects a shock absorber. In the upper member portion, a portion formed along the suspension tower portion is at a height below the upper wall portion. Therefore, the upper wall portion of the suspension tower portion is disposed at a higher position.

[0011] For the upper member portion, a portion formed along the suspension tower portion is formed along the peripheral portion of the upper wall portion so as to bypass the shock absorber inward in the vehicle width direction when viewed from above. Thus, even if a portion formed along the suspension tower portion in the upper member portion is disposed at a height below the upper wall portion, when forming the wheel arch, it is possible to pull out the mold outward in the vehicle width direction under the condition that a portion of the mold forming the upper wall portion does not interfere with the upper member portion.

[0012] The body structure of the second aspect of the present disclosure is that in the body structure of the first aspect, the suspension tower portion has a longitudinal wall portion that extends downward from the peripheral portion of the upper wall portion and at least a part of which is disposed inside the shock absorber in the vehicle width direction, and the baffle upper member portion has a lower rib that faces the upper wall portion and extends outward in the vehicle width direction from the longitudinal wall portion.

[0013] According to the second aspect of the present disclosure, the longitudinal wall portion has a shape in which at least a part thereof is disposed inside the vehicle width direction of the shock absorber, and can be formed together with the upper wall portion by a mold that is pulled out toward the outside in the vehicle width direction. Here, a portion surrounded by the upper wall portion and the longitudinal wall portion of the suspension tower portion and the lower side rib of the upper member portion forms a recess having a substantially U-shaped cross section that is open to the outside in the vehicle width direction. Therefore, the recess including the lower side rib can be formed by a mold that is pulled out toward the outside in the vehicle width direction.

[0014] The body structure according to the third aspect of the present disclosure is such that, in the body structure according to the first aspect, the suspension tower portion includes a longitudinal wall portion that extends in the vehicle up-and-down direction and at least a part thereof is disposed inside the vehicle width direction of the shock absorber, and the baffle upper member portion includes an outer wall portion that extends downward from the peripheral edge portion of the upper wall portion, an inner wall portion that is formed to face the outer wall portion at the upper end portion of the longitudinal wall portion, and a bottom portion that connects the lower end portion of the outer wall portion and the lower end portion of the inner wall portion.

[0015] According to the third aspect of the present disclosure, a recess is formed that is surrounded by the outer wall portion and the bottom portion of the baffle upper member portion and the inner wall portion formed at the upper end portion of the upper member portion. Therefore, since the wheel arch has, in addition to the upper wall portion and the longitudinal wall portion of the suspension tower portion, the outer wall portion and the bottom portion of the baffle upper member portion, and the outer wall portion is orthogonal to the bottom portion, the rigidity of the baffle upper member portion is improved as compared with the case where the baffle upper member portion is constituted only by ribs extending in one direction.

[0016] The body structure according to the fourth aspect of the present disclosure is such that, in the body structure according to the third aspect, the baffle upper member portion includes a plurality of reinforcing ribs that respectively extend in the vehicle up-and-down direction and connect the outer wall portion, the inner wall portion, and the bottom portion, and are provided at intervals from each other.

[0017] According to the fourth aspect of the present disclosure, it is strengthened by a plurality of reinforcing ribs provided at intervals from each other so that the recess surrounded by the inner wall portion, the bottom portion, and the outer wall portion is not crushed. Therefore, the rigidity of the baffle upper member portion is improved. In addition, the recess is formed to be open to the upper side in the vehicle and has a substantially U-shaped cross section. Therefore, when forming the recessed surface of the recess, the plurality of reinforcing ribs can also be formed by a mold that is pulled out toward the upper side in the vehicle.

[0018] The body structure according to the fifth aspect of the present disclosure is such that, in the body structure according to the first aspect, a pair of left and right front side member portions that extend in the vehicle front-and-rear direction are disposed on the lower side in the vehicle and inside the vehicle width direction of the suspension tower portion in the pair of left and right wheel arches, and the front side member portions and the pair of left and right wheel arches are integrally formed.

[0019] According to the fifth aspect of the present disclosure, not only the cross member and the pair of left and right wheel arches but also the pair of left and right front side members are integrally formed, thereby reducing the number of parts and the number of manufacturing steps.

[0020] As described above, the vehicle body structure of the first aspect of the present disclosure has the excellent effect of enabling a pair of wheel arches and a cross member to be integrally formed while ensuring a large vertical dimension of the space for accommodating the suspension towers at the front of the vehicle.

[0021] The vehicle body structure according to the second aspect of the present disclosure has the excellent effect of being able to configure the apron upper member of the vehicle with a simple structure and improving the rigidity.

[0022] The vehicle body structure according to the third aspect of the present disclosure has the excellent effect of increasing the rigidity of the apron upper member portion.

[0023] The vehicle body structure according to the fourth aspect of the present disclosure has the excellent effect of being able to easily mold the apron upper member while improving its rigidity.

[0024] The vehicle body structure according to the fifth aspect of the present disclosure has the excellent effect of being able to reduce the number of components and the number of manufacturing steps. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Below, use Figures 1 to 4The body of a vehicle to which the body structure according to an embodiment of the present disclosure is applied will be described. In addition, arrow marks FR, arrow mark UP, and arrow mark RH appropriately shown in the respective drawings indicate the front side, the upper side, and the right side in the left - right direction (width direction) of the vehicle, respectively. Further, when the directions of front - rear, up - down, and left - right are used without special description in the following description, they are assumed to represent the front - rear in the vehicle front - rear direction, the up - down in the vehicle up - down direction, and the left - right in the vehicle left - right direction (width direction), respectively.

[0032] In Figure 1 , the body 14 of a vehicle 12 to which the body structure according to the present embodiment is applied is shown. The body 14 is configured to include a front body 16 that forms a part on the front side of the vehicle, a center body 18 that forms the central part in the vehicle front - rear direction, and a rear body 20 that forms a part on the rear side of the vehicle.

[0033] The front body 16 includes, for example, a front casting 22 integrally formed by die - casting aluminum. The front casting 22 includes a lateral member portion 24 extending in the vehicle width direction on the vehicle front side of the center body 18, and a pair of left - right wheel arches 26 provided on both sides in the vehicle width direction of the lateral member portion 24. In addition, since the front casting 22 is configured to be left - right symmetric, in the following description, mainly the structure on the right side will be described, and the description of the structure on the left side will be omitted.

[0034] The wheel arch 26 is configured to be able to house a wheel (not shown) and a shock absorber 28 (omitted in the drawing) to which a spring (not shown) is attached (refer to Figure 3 ) on the outer side in the vehicle width direction.

[0035] The wheel arch 26 includes a suspension tower portion 30 to which the shock absorber 28 (refer to Figure 3 ) is connected. The suspension tower portion 30 is formed in a box shape with the outer side and the lower side in the vehicle width direction open. Details of the suspension tower portion 30 will be described in detail later using Figure 2 .

[0036] The wheel arch 26 has a front side member portion 32 extending in substantially the vehicle front - rear direction on the lower side in the vehicle width direction and the inner side in the vehicle width direction of the suspension tower portion 30. The front side member portion 32 forms the skeleton of the lower part of the front body 16.

[0037] In addition, the wheel arch 26 has a baffle upper member portion 34 (hereinafter referred to as "upper member portion 34") extending in substantially the vehicle front - rear direction on the upper side in the vehicle width direction and the outer side in the vehicle width direction of the front side member portion 32. The rear end portion of the upper member portion 34 is joined to the front pillar 36. The upper member portion 34 forms the upper - side lateral skeleton in the front body 16.

[0038] At the vehicle front side of the front side member portion 32, a crash box 38 that extends in the vehicle front-rear direction and can absorb the crash energy during a frontal collision of the vehicle 12 is provided. The front end portions of the left and right crash boxes 38 are connected together in the vehicle width direction through a front bumper 40.

[0039] In Figure 2 , a rear perspective view showing the periphery of the right suspension tower portion 30 in an enlarged manner is shown. The wheel arch 26 includes a wheel arch front portion 42 formed on the vehicle front side of the suspension tower portion 30 and a wheel arch rear portion 44 formed on the vehicle rear side of the suspension tower portion 30. At the upper end portion of the wheel arch front portion 42, a front flange portion 42A extending outward in the vehicle width direction is formed. Similarly, at the upper end portion of the wheel arch rear portion 44, a rear flange portion 44A extending outward in the vehicle width direction is formed.

[0040] In addition, the suspension tower portion 30 is configured to include an upper wall portion 46 that extends in a substantially horizontal direction and is connected to a shock absorber 28 (refer to Figure 3 ) on the vehicle lower side, and a longitudinal wall portion 48 that extends downward from the peripheral portion of the upper wall portion 46. The upper wall portion 46 is flush with the front flange portion 42A and the rear flange portion 44A.

[0041] As Figure 3 shown, the longitudinal wall portion 48 is formed in a substantially U-shaped configuration that opens outward in the vehicle width direction when viewed in a flat section. The longitudinal wall portion 48 is configured to include a front wall portion 48A that extends in the vehicle width direction on the vehicle front side, a side wall portion 48B that extends rearward from the inner end portion of the front wall portion 48A in the vehicle width direction, and a rear wall portion 48C that extends outward in the vehicle width direction from the rear end portion of the side wall portion 48B. 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 are provided to face each other and move away from each other as they approach the outer side in the vehicle width direction. Thus, the suspension tower portion 30 can be formed by a die that is pulled out outward in the vehicle width direction.

[0042] As Figure 2 shown, the upper member portion 34 includes lower side ribs 50 formed along the wheel arch front portion 42, the longitudinal wall portion 48, and the wheel arch rear portion 44. The lower side ribs 50 extend outward in the vehicle width direction from the wheel arch front portion 42, the longitudinal wall portion 48, and the wheel arch rear portion 44, respectively.

[0043] The lower rib 50 is configured to include a front portion 50A formed along the front portion 42 of the wheel arch, an intermediate portion 50B formed along the longitudinal wall portion 48 of the suspension tower portion 30, and a rear portion 50C formed along the rear portion 44 of the wheel arch.

[0044] The front portion 50A is opposed to the front flange portion 42A and is formed on the vehicle lower side of the front flange portion 42A. Similarly, the rear portion 50C is opposed to the rear flange portion 44A and is formed on the vehicle lower side of the rear flange portion 44A.

[0045] In addition, the intermediate portion 50B is opposed to the upper wall portion 46 and is formed on the vehicle lower side of the upper wall portion 46. The intermediate portion 50B is formed along the front wall portion 48A, the side wall portion 48B, and the rear wall portion 48C, respectively, and is formed in a substantially U-shape that is open to the outside in the vehicle width direction in a plan view. The intermediate portion 50B is formed in a continuous manner with the front portion 50A and the rear portion 50C. That is, as Figure 3 shown, the lower rib 50 is formed along the upper portion of the front portion 42 of the wheel arch, the upper portion of the longitudinal wall portion 48 of the suspension tower portion 30, and the upper portion of the rear portion 44 of the wheel arch in such a manner as to bypass the shock absorber 28 to the inside in the vehicle width direction in a plan view.

[0046] As Figure 4 shown, the front side member portion 32 is formed in a substantially E-shape that is open to the outside in the vehicle width direction in a longitudinal sectional view when viewed from the vehicle front side. In addition, the upper portion of the suspension tower portion 30 is formed in a substantially U-shape that is open to the outside in the vehicle width direction by extending the lower rib 50 from the longitudinal wall portion 48. The portion surrounded by the upper wall portion 46, the side wall portion 48B, and the lower rib 50 becomes a recess 52 having a substantially U-shaped cross section that is open to the outside in the vehicle width direction.

[0047] (Function)

[0048] Next, the function of the present embodiment will be described.

[0049] According to the body structure according to the present embodiment, as Figure 1 shown, at the front casting 22 of the front body 16 of the vehicle 12, the lateral member portion 24 extending in the vehicle width direction and the pair of left and right wheel arches 26 are integrally formed.

[0050] As Figure 2 shown, the suspension tower portion 30 includes an upper wall portion 46 that extends in the vehicle front-rear direction and the vehicle width direction and to which the shock absorber 28 (see Figure 3 ) is connected. At the upper member portion 34, the intermediate portion 50B formed along the suspension tower portion 30 is located at a height below the upper wall portion 46. Therefore, the upper wall portion 46 of the suspension tower portion 30 is disposed at a relatively high position.

[0051] As Figure 3 shown, for the upper member portion 34, the portion formed along the suspension tower portion 30 is formed along the peripheral portion of the upper wall portion 46 so as to bypass the shock absorber 28 inward in the vehicle width direction when viewed from above. Thus, as Figure 2 and Figure 4 shown, even if the intermediate portion 50B in the upper member portion 34 is arranged at a height lower than that of the upper wall portion 46, when forming the wheel arch 26, the mold (not shown) for forming the upper wall portion 46 can be pulled out outward in the vehicle width direction under the condition that there is no interference between the upper member portion 34 and the mold for forming the upper wall portion 46.

[0052] In addition, according to the vehicle body structure according to the present embodiment, as Figure 3 shown, the longitudinal wall portion 48 has a shape in which the side wall portion 48B is arranged inward in the vehicle width direction of the shock absorber 28, and can be formed together with the upper wall portion 46 as shown in Figure 4 by a mold pulled out outward in the vehicle width direction. Here, the portion surrounded by the side wall portion 48B and the lower rib 50 by the upper wall portion 46 becomes a recess 52 having a substantially U-shaped cross section open outward in the vehicle width direction. Therefore, the recess 52 including the lower rib 50 can be formed by a mold pulled out outward in the vehicle width direction.

[0053] Furthermore, according to the vehicle body structure according to the present embodiment, as Figure 1 shown, not only the lateral 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 formed. Thus, the number of components and the manufacturing process can be reduced.

[0054] 〔Supplementary description of the above embodiment〕

[0055] Although in the above embodiment, it is described that the lower rib 50 constituting the upper member portion 34 faces the upper wall portion 46 and is provided at a lower side than the upper wall portion 46, it is not limited thereto, and the upper member portion only needs to be formed at a height below the upper wall portion. For example, the vehicle body structure according to the modified example shown in Figure 5 and Figure 6 can also be adopted. In addition, in the following modified examples, for the same structures as those in the above embodiment, the same reference numerals will be used and their descriptions will be appropriately omitted.

[0056] (Modified example)

[0057] In Figure 5In it, a main part enlarged front perspective view of a front casting 64 of a body 62 of a vehicle 60 having a vehicle front structure according to a modification is shown. The front casting 64 includes a lateral member portion 24 (see Figure 1 ) that extends in the vehicle width direction at the vehicle front, and wheel arches 66 respectively provided on both sides in the vehicle width direction of the lateral member portion 24. A pair of wheel arches 66 and the lateral member portion 24 (see Figure 1 ) are integrally formed.

[0058] As Figure 5 shown, the wheel arch 66 includes a suspension tower portion 68, a fender upper member portion 70 (hereinafter referred to as "upper member portion 70"), and a front side member portion 32.

[0059] The suspension tower portion 68 is configured to include an upper wall portion 72 that extends in a substantially horizontal direction and connects a shock absorber 28 (see Figure 3 ), and a longitudinal wall portion 48 that extends in the vehicle up-and-down direction. The upper wall portion 72 and the longitudinal wall portion 48 are connected together by the upper member portion 70.

[0060] The upper member portion 70 is provided at a height below the upper wall portion 72, and includes a recess 74 that is recessed toward the vehicle lower side, and a plurality of reinforcing rib strips 76 that are provided at intervals in the recess 74.

[0061] As Figure 5 and Figure 6 shown, the recess 74 is configured to include an outer wall portion 78 that extends from a peripheral portion of the upper wall portion 72 toward the vehicle lower side, an inner wall portion 80 that is formed to face the outer wall portion 78 at an upper end portion of the longitudinal wall portion 48, and a bottom portion 82 that connects a lower end portion of the outer wall portion 78 and a lower end portion of the inner wall portion 80.

[0062] The plurality of reinforcing rib strips 76 respectively extend in the vehicle up-and-down direction in the recess 74 and connect the outer wall portion 78, the inner wall portion 80, and the bottom portion 82. As an example, an upper surface of the reinforcing rib strip 76 is flush with the upper wall portion 72.

[0063] According to this modification, a recess 74 surrounded by the outer wall portion 78, the bottom portion 82, and the inner wall portion 80 is formed. Therefore, since the wheel arch 66 has, in addition to the upper wall portion 72 and the longitudinal wall portion 48 of the suspension tower portion 68, the outer wall portion 78 and the bottom portion 82 of the upper member portion 70, and the outer wall portion 78 is orthogonal to the bottom portion 82, the rigidity of the upper member portion 70 is improved as compared with a structure in which the upper member portion is constituted by ribs extending in one direction.

[0064] In addition, it is strengthened by a plurality of reinforcing ribs 76 arranged at intervals from each other, so that the recess 74 surrounded by the inner wall portion 80, the bottom portion 82, and the outer wall portion 78 is not crushed. Therefore, the rigidity of the upper member portion 70 is improved. In addition, the recess 74 is formed to be open toward the vehicle upper side and have a substantially U-shaped cross section. Therefore, when forming the recessed surface of the recess 74, the plurality of reinforcing ribs 76 can also be formed by a mold that is pulled out toward the vehicle upper side.

[0065] In addition, in the above-described embodiment, a reinforcing rib may be provided on the vehicle upper side of the lower rib 50. In this case, in order to pull out the mold outward in the vehicle width direction, the reinforcing rib will be provided along the vehicle width direction. A plurality of such reinforcing ribs may also be provided as in the modification. In addition, the reinforcing rib 76 may not be formed in the recess 74 of the modification.

[0066] In addition, although the front casting 22 of the above-described embodiment and the front casting 64 of the modification are described as being integrally formed by aluminum die casting, it is not limited thereto. For example, the lateral member portion and the pair of left and right wheel arch covers may be integrally formed by resin. In this case, as in the above-described embodiment and the modification, the pair of left and right front side members may also be integrally formed by resin.

[0067] Furthermore, although in the above-described embodiment and the modification, the pair of left and right front side member portions 32 are also described as being integrally formed components, it is not limited thereto, and the pair of left and right front side members may be formed separately from the pair of left and right wheel arch covers and the lateral member portion.
