Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the above prior art, a plurality of ribs are formed on the outside in the vehicle width direction of the cast body. Therefore, when the cast body is released from the mold for forming the cast body, the cast body (integrally formed member) may be deformed due to the release resistance caused by the formation of the plurality of ribs.

[0005] In consideration of the above facts, an object of the present invention is to obtain a vehicle front structure capable of suppressing deformation of an integrally formed member during the molding of the integrally formed member.

Means for Solving the Problems

[0006] The front structure of the vehicle according to the first embodiment comprises a pair of left and right wheelhouses, each containing a vertical wall portion that extends in the vehicle longitudinal direction and in the vehicle vertical direction, with the left and right front wheels respectively arranged therein; a cross member that extends in the vehicle width direction and connects the left and right wheelhouses, and is molded integrally with the left and right wheelhouses; and a pair of left and right pillars that are provided on the rearward side in the vehicle longitudinal direction of the left and right wheelhouses, extend in the vehicle longitudinal direction and in the vehicle vertical direction, and are molded integrally with the left and right wheelhouses, with a first rib formed on each of the left and right pillars that connects the inner surface in the vehicle width direction to the cross member.

[0007] The front vehicle structure according to the first embodiment includes a pair of left and right wheelhouses, a cross member, and a pair of left and right pillars. The left and right front wheels can be positioned in the pair of left and right wheelhouses, and the pair of left and right wheelhouses are configured to include vertical wall portions that extend in the longitudinal direction and the vertical direction of the vehicle.

[0008] Furthermore, the cross member extends in the vehicle width direction, connecting the left and right wheelhouses, and is molded integrally with the left and right wheelhouses. In addition, the left and right pillars are each located on the rearward side in the vehicle longitudinal direction relative to the left and right wheelhouses, and extend in both the vehicle longitudinal and vertical directions, respectively, and are molded integrally with the left and right wheelhouses. In other words, in this embodiment, the left and right wheelhouses, the cross member, and the left and right pillars are molded integrally (integrally molded members).

[0009] In this embodiment, a first rib is formed on each of the left and right pillars, connecting the inner surface in the vehicle width direction to the cross member. By forming this first rib, after the integrally molded member is formed, the compressive force of the first rib can resist deformation that would cause the left and right pillars to tilt inward in the vehicle width direction, thereby suppressing deformation of the pillars.

[0010] The vehicle front structure according to the second embodiment is a vehicle front structure according to the first embodiment in which the first rib is provided including the boundary portion with the cross member in the pillar, and is a triangular rib that forms a substantially triangular shape when viewed from the rear side of the vehicle.

[0011] In the vehicle front structure according to the second embodiment, the first rib is provided including the boundary portion with the cross member of the pillar, and is a triangular rib that forms a substantially triangular shape when viewed from the rear side of the vehicle. In this embodiment, by forming a triangular rib at the boundary portion with the cross member of the pillar, it is possible to effectively suppress the deformation of the pillar with the minimum necessary size and simple shape.

[0012] The vehicle front structure according to the third embodiment is a vehicle front structure according to the first or second embodiment, wherein a second rib is erected along the vehicle vertical direction from the outer surface in the vehicle width direction of the pillar.

[0013] In the vehicle front structure according to the third embodiment, a second rib is erected on the outer surface of the pillar in the vehicle width direction, and this second rib is formed along the vehicle vertical direction. As a result, in this embodiment, when the integrally molded member is released from the mold during molding, the second rib provides release resistance to the pillar. Due to this release resistance, when the integrally molded member is released from the mold, a force acts on the left and right pair of pillars toward the outside in the vehicle width direction. As a result, in this embodiment, it is possible to suppress inward deformation (tilting) of the left and right pair of pillars toward the vehicle width direction with a simple configuration.

[0014] The front vehicle structure according to the fourth embodiment is a front vehicle structure according to any one of the first to third embodiments, wherein a plurality of third ribs are erected from the vertical wall portion outward in the vehicle width direction between the suspension tower provided in the wheelhouse and the pillar.

[0015] In the front vehicle structure according to the fourth embodiment, a plurality of third ribs are erected between the suspension tower and the pillar provided in the wheelhouse, and these plurality of third ribs are formed extending outward in the vehicle width direction from the vertical wall portion. This makes it possible to improve the rigidity of the space between the suspension tower and the pillar (the so-called upper member) and to suppress deformation of the upper member.

[0016] The vehicle front structure according to the fifth embodiment is the vehicle front structure according to the fourth embodiment, wherein the draft angle of the third rib is greater in inclination than the draft angle of the ribs in parts other than the upper member.

[0017] In the vehicle front structure according to the fifth embodiment, the draft angle of the third rib is greater than the draft angle of the ribs in parts other than the upper member (e.g., the wheelhouse), which makes it possible to improve the release properties of the third rib. As a result, in this embodiment, when the integrally molded member is released from the mold during molding, it is possible to reduce the adverse effects on release properties (deformation, etc.) caused by the provision of multiple third ribs. [Effects of the Invention]

[0018] As described above, the vehicle front structure according to the present invention can suppress deformation of the integrally molded member during the molding of the integrally molded member. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0020] Hereinafter, the vehicle front structure according to an embodiment of the present invention will be described with reference to the drawings. In each figure, the arrow FR appropriately shown indicates the front side in the vehicle front-rear direction, and the arrow UP indicates the upper side in the vehicle up-down direction. The arrow RH indicates the right side in the vehicle width direction, and in the present embodiment, it indicates the outside in the vehicle width direction. Hereinafter, when simply using the front-rear, up-down, and left-right directions for explanation, unless otherwise specified, it shall indicate 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 (vehicle width direction).

[0021] <Configuration of the vehicle front structure> First, the configuration of the vehicle front structure according to the present embodiment will be described.

[0022] FIG. 1 shows the front part (vehicle front part) 11 of a vehicle 12 to which a vehicle front structure 10 according to the present embodiment is applied. Although not shown in the figure, this vehicle 12 is, for example, an electric vehicle and a fuel cell vehicle that run on power generated by a power unit.

[0023] In the vehicle 12 shown in FIG. 1, wheelhouses 14 in which front wheels (not shown) are arranged are provided on the left and right of the vehicle front part 11, respectively, and the right wheelhouse 14 and the left wheelhouse 14 are connected by a cross member 16. At the upper end of each wheelhouse 14, apron upper members 18 extend along the vehicle front-rear direction, respectively, and suspension towers (hereinafter referred to as "suspension towers") 20 are provided inside the apron upper members 18 in the vehicle width direction, respectively.

[0024] An upper member 22 extending in the vehicle up-down direction and the vehicle front-rear direction is provided on the rear side of the suspension tower 20 and outside the suspension tower 20 in the vehicle width direction. A front side member 24 extending in the vehicle up-down direction and the vehicle front-rear direction is provided below the suspension tower 20 and the upper member 22. And a front pillar (pillar) 26 extending in the vehicle up-down direction and the vehicle front-rear direction is provided on the rear side of the upper member 22 and the front side member 24.

[0025] The front end of a roof side rail, which supports the upper end of a front door (not shown) and extends in the longitudinal direction of the vehicle, is connected to the upper end of the front pillar 26. The front end of a rocker, which is located on the outer side of a floor panel (not shown) in the vehicle width direction and extends in the longitudinal direction of the vehicle, is connected to the lower side of the front pillar 26.

[0026] In this embodiment, the left and right wheel houses 14 including the suspension tower 20 and front side members 24, the left and right upper members 22, the cross member 16 and the front pillar 26 are integrally formed by casting using, for example, an aluminum alloy or a magnesium alloy as the material (integrated molded member 25).

[0027] In this embodiment, the integrally molded member 25 is formed by sliding the mold outward in the vehicle width direction when forming the outer surface in the vehicle width direction of, for example, the wheelhouse 14, upper member 22, and front pillar 26, due to the structure of the mold. For this reason, the wheelhouse 14 and front pillar 26 in this embodiment are formed so that the outer side in the vehicle width direction is open.

[0028] (Wheelhouse) First, the wheelhouse 14 in this embodiment will be described.

[0029] As described above, the pair of left and right wheelhouses 14 are composed of a suspension tower 20 and a front side member 24, respectively. As shown in Figure 1, the wheelhouse 14 has a vertical wall portion 28 that extends in the vehicle's longitudinal direction and vertical direction inside the vehicle's fender panel (not shown). The vertical wall portion 28 is formed to bulge inward in the vehicle's width direction along the shape of the suspension tower 20 above the front side member 24, which will be described later.

[0030] Furthermore, as mentioned above, an apron upper member 18 is provided at the upper end of the wheelhouse 14, and a front side member 24 extends in the longitudinal direction of the vehicle from the lower part of the wheelhouse 14.

[0031] The front side member 24 is composed of an upper wall portion 30 that forms the upper end of the front side member 24 and a lower wall portion 32 that forms the lower end of the front side member 24, both extending along the longitudinal direction of the vehicle. Between the upper wall portion 30 and the lower wall portion 32, multiple lateral wall portions 34 extend along the longitudinal direction of the vehicle, and the upper wall portion 30, the lower wall portion 32, and the lateral wall portions 34 are each erected outward from the vertical wall portion 28 in the vehicle width direction.

[0032] Furthermore, on the front side member 24A, multiple vertical ribs 36 are provided between the upper wall portion 30 and the lower wall portion 32, oriented in the vertical direction of the vehicle, and these vertical ribs 36 are arranged along the longitudinal direction of the vehicle.

[0033] On the other hand, on the rear 24B side of the front side member 24, multiple inclined ribs 38 that slope upward towards the rear of the vehicle and multiple inclined ribs 40 that slope downward towards the rear of the vehicle are provided between the upper wall portion 30 and the lower wall portion 32, and are connected to each other with the lateral wall portion 34 in between, forming an apparent truss structure. In this way, the inclined ribs 38 and 40 are connected to each other with the lateral wall portion 34 in between, making it difficult for bending moments to occur and suppressing deformation.

[0034] Furthermore, approximately cylindrical or columnar bosses 42 are provided at the intersections of the inclined ribs 38 and 40 with the side wall portion 34, and on the side wall portion 34. These bosses 42 serve as bases to which ejection pins (not shown) that are used to release the integrally molded member 25, including the wheelhouse 14, from the mold during molding, make contact.

[0035] The position and size of the boss 42 can be appropriately changed by adjusting the mass balance of the integrally molded member 25. Furthermore, the boss 42 may be used not only as a base for the ejector pin to contact, but also as a base for fastening to other parts.

[0036] (Upper Member) Next, the upper member 22 in this embodiment will be described.

[0037] In this embodiment, the left and right pair of upper members 22 are provided along the longitudinal direction of the vehicle, between the suspension tower 20 and the front pillar 26 of the wheelhouse 14, and above the front side member 24.

[0038] The upper member 22 is connected to the wheelhouse 14 on the inside in the vehicle width direction and has a vertical wall portion 28 that extends in the vehicle longitudinal direction and in the vehicle vertical direction. Furthermore, the upper member 22 has a roughly triangular shape when viewed from the outside of the vehicle in a side view, and an upper wall portion 46 is erected at the upper end of the upper member 22, connecting to the upper end portion 44 that constitutes the upper end of the apron upper member 18, extending outward in the vehicle width direction from the upper end of the vertical wall portion 28 and along the vehicle longitudinal direction.

[0039] Furthermore, the rear end of the upper member 22 has a rear wall portion 48 that forms the boundary between the rear end of the upper wall portion 46 and the front pillar 26, which is erected from the rear end of the vertical wall portion 28 outward in the vehicle width direction and is formed along the vehicle's vertical direction. In addition, the front end of the upper member 22 has an inclined rib 50 that forms the boundary with the wheelhouse 14, which is erected from the vertical wall portion 28 outward in the vehicle width direction and is formed to be inclined downward towards the vehicle as it approaches the rear of the vehicle.

[0040] Furthermore, a rear wall portion 52 is provided between the upper end of the inclined rib 50 and the front end of the upper wall portion 46, forming the rear end of the apron upper member 18 and extending in the vehicle's vertical and vehicle width directions. Additionally, the lower end of the upper member 22 has a lower wall portion 54 that forms a boundary with the front side member 24, which is erected from the vertical wall portion 28 outward in the vehicle width direction and formed along the vehicle's longitudinal direction.

[0041] In other words, in this embodiment, the upper member 22 is bounded by the upper wall portion 46, the rear wall portion 52 of the apron upper member 18, the inclined rib 50, the rear wall portion 48, and the lower wall portion 54, which form the boundary with other parts of the integrally molded member 25.

[0042] Here, multiple first circular arc ribs (third ribs) 56 extend from the inclined rib 50, extending upwards towards the rear of the vehicle as they move towards the rear of the vehicle, and bulging gently in a convex shape towards both the rear and downward sides of the vehicle. These first circular arc ribs 56 are erected from the vertical wall portion 28 outwards in the vehicle width direction and are arranged with gaps between them. The upper ends of the first circular arc ribs 56 are connected to the upper wall portion 46 and the rear wall portion 48 (boundary of the upper member 22), respectively.

[0043] Furthermore, in this embodiment, multiple second arc ribs (third ribs) 58 intersect multiple first arc ribs 56. These second arc ribs 58 are formed to bulge gently in a convex shape towards the rear of the vehicle, downwards towards the vehicle, and both towards the rear and upwards of the vehicle.

[0044] Furthermore, these second arc ribs 58 are erected from the vertical wall portion 28 outward in the vehicle width direction and are arranged with gaps between them. The front end of the second arc rib 58 is connected to the inclined rib 50, the rear wall portion 52, and the upper wall portion 46 (boundary of the upper member 22), respectively, while the rear end of the second arc rib 58 is connected to the lower wall portion 54 and the rear wall portion 48 (boundary of the upper member 22), respectively.

[0045] Furthermore, in this embodiment, as shown in Figures 2(A) and (B), the draft angle θ of the first circular arc rib 56 and the second circular arc rib 58 is larger in inclination angle than the draft angle θ' of the rib 59 formed in parts other than the upper member 22, such as the wheelhouse 14 (see Figure 1) (θ>θ').

[0046] (Front pillar) Next, the front pillar 26 in this embodiment will be described.

[0047] As shown in Figure 1, in this embodiment, the left and right pair of front pillars 26 are provided on the rear sides of the left and right pair of upper members 22 and the left and right pair of front side members 24, respectively, and extend in the vertical and longitudinal directions of the vehicle. The left and right pair of front pillars 26 are connected by a cross member 16 that extends in the vehicle width direction.

[0048] In this embodiment, a triangular rib (first rib) 60 is provided on the inner surface 26A side in the vehicle width direction of the front pillar 26 and at the boundary portion 26B with the cross member 16, connecting the front pillar 26 and the cross member 16. This triangular rib 60 is provided in two locations, for example, at the front and rear of the vehicle, and is formed in a substantially triangular shape when viewed from the rear of the vehicle.

[0049] Here, the front pillar 26, which extends in the vertical and longitudinal directions of the vehicle, and the cross member 16, which extends along the width direction of the vehicle, are formed in a substantially perpendicular manner. Therefore, a rectangular plate-shaped gusset 61 is provided between the front pillar 26 and the cross member 16.

[0050] In this way, by providing a gusset 61 between the front pillar 26 and the cross member 16, the boundary portion 26B of the front pillar 26 with the cross member 16 is located above the gusset 61. In other words, the boundary portion 26B of the front pillar 26 with the cross member 16, as referred to here, is the part that becomes the starting point of deformation when the front pillar 26 deforms inward in the vehicle width direction.

[0051] Furthermore, in this embodiment, a second rib 62 is erected along the vehicle's vertical direction from the outer surface 26C in the vehicle width direction of the front pillar 26, and the lower end of the second rib 62 overlaps with the triangular rib 60 when viewed from the outside in the vehicle width direction. The cross-sectional shape of the second rib 62 when cut in the width direction substantially perpendicular to the longitudinal direction is triangular, rectangular, trapezoidal, etc.

[0052] <Function and effect of the vehicle's front structure> Next, the operation and effects of the vehicle front structure according to this embodiment will be described.

[0053] In this embodiment, as shown in Figure 1, a pair of left and right wheelhouses 14, a cross member 16, and a pair of left and right front pillars 26 are provided, and these are integrally molded as an integral molded member 25.

[0054] In this embodiment, a triangular rib 60 is provided on the inner surface 26A side of the left and right front pillars 26 and on the boundary portion 26B with the cross member 16, connecting the front pillars 26 and the cross member 16.

[0055] In this embodiment, the formation of the triangular rib 60 allows the compressive force of the triangular rib 60 to resist deformation that would cause the left and right front pillars 26 to tilt inward in the vehicle width direction after the integrally molded member 25 has been formed, thereby suppressing deformation of the front pillars 26.

[0056] In this way, by suppressing the deformation of the left and right front pillars 26 toward the inside in the vehicle width direction, in this embodiment it becomes possible to mold the integrally molded member 25 to include the left and right front pillars 26.

[0057] Furthermore, in this embodiment, by using a triangular rib 60, it is possible to effectively suppress deformation of the front pillar 26 with the minimum necessary size and simple shape. In this way, suppressing deformation of the front pillar 26 with the minimum necessary size also contributes to weight reduction of the vehicle 12.

[0058] Furthermore, in this embodiment, a second rib 62 is erected from the outer surface 26C of the front pillar 26, and the second rib 62 is formed along the vertical direction of the vehicle.

[0059] As a result, in this embodiment, when the integrally molded member 25 is molded and then released from the mold, the second rib 62 provides release resistance to the front pillar 26. Due to this release resistance, when the integrally molded member 25 is released from the mold, a force acts on the left and right pair of front pillars 26 toward the outside in the vehicle width direction. As a result, in this embodiment, it is possible to suppress inward deformation (tilting) of the left and right pair of front pillars 26 toward the vehicle width direction with a simple configuration.

[0060] Furthermore, in this embodiment, multiple first arc ribs 56 and second arc ribs 58 are erected on the upper member 22, which is located between the suspension tower 20 provided in the wheelhouse 14 and the front pillar 26. These first arc ribs 56 and second arc ribs 58 are formed extending outward in the vehicle width direction from the vertical wall portion 28.

[0061] As a result, in this embodiment, it is possible to improve the rigidity of the upper member 22 itself and suppress deformation of the upper member 22. As a result, it is possible to suppress tilting along the vehicle width direction of the pair of left and right front pillars 26 provided on the rear side of the vehicle of the upper member 22. In addition, in the upper member 22, a plurality of first arc ribs 56 and second arc ribs 58 are erected from the vertical wall portion 28, so that when a collision occurs in the longitudinal direction of the vehicle, the plurality of first arc ribs 56 and second arc ribs 58 are crushed, thereby absorbing the collision energy.

[0062] In this embodiment, as shown in Figures 2(A) and (B), the draft angle θ of the first circular arc rib 56 and the second circular arc rib 58 is greater than the draft angle θ' of the rib 59 formed in a part other than the upper member 22 (θ>θ').

[0063] As a result, in this embodiment, it is possible to improve the release properties of the first arc rib 56 and the second arc rib 58, and when the integrally molded member 25 is released from the mold during molding, it is possible to reduce the adverse effects on release properties (deformation, etc.) caused by the provision of multiple first arc ribs 56 and second arc ribs 58.

[0064] <Supplementary explanation of the above embodiment> In the above embodiment, it is explained that the upper member 22 is bounded from other parts by the rear wall portion 52, inclined rib 50, and lower wall portion 54 of the apron upper member 18. However, the boundary is set here for convenience in order to explain the upper member 22, and since the upper member 22 is part of the integrally molded member 25 including the wheelhouse 14, the extent of the upper member 22 can be changed as appropriate. For example, the rear end of the front side member 24 may be part of the upper member 22.

[0065] Furthermore, in this embodiment, the first arc rib 56 and the second arc rib 58 are formed in an arc shape, but they do not necessarily have to be formed in an arc shape and may be formed in a straight line. Also, the thickness of the first arc rib 56 and the second arc rib 58 does not necessarily have to be constant along the extension direction; for example, the thickness may be greater at the intersection with other parts.

[0066] Furthermore, the heights of the first arc rib 56 and the second arc rib 58 do not necessarily have to be constant along the extension direction. They may be partially lowered to speed up cooling, taking into consideration the balance of cooling time with other parts of the upper member 22 during the molding of the integrally molded member 25.

[0067] Furthermore, in this embodiment, triangular ribs 60 connecting the inner surfaces 26A of the left and right front pillars 26 to the cross member 16 are provided at the boundary portion 26B between the front pillars 26 and the cross member 16. However, the triangular ribs 60 only need to be provided including the boundary portion 26B, and may be further formed along the vertical direction of the vehicle. Also, the ribs formed including the boundary portion 26B do not need to be triangular ribs 60. For example, they may have a substantially trapezoidal shape when viewed from the rear of the vehicle.

[0068] Furthermore, in this embodiment, a second rib 62 is erected from the outer surface 26C of the front pillar 26, and the second rib 62 is formed along the vertical direction of the vehicle. When viewed from the outside in the vehicle width direction, the lower end of the second rib 62 overlaps with the triangular rib 60, but it is not necessarily required that the lower end of the second rib 62 overlaps with the triangular rib 60 when viewed from the outside in the vehicle width direction.

[0069] By the way, in this embodiment, the left and right wheelhouses 14, the left and right upper members 22, and the cross member 16 are integrally formed as a single molded member 25 by casting using an aluminum alloy or the like as the material, but this is not the only option. The integral molded member 25 may be integrally formed from, for example, CFRP, GFRP, or the like.

[0070] Furthermore, in this embodiment, the front side member 24 is molded integrally with the wheelhouse 14, but it is not necessarily required that they be molded integrally. The front side member 24 may be fixed as a separate component to the lower side of the wheelhouse 14. In this case, it becomes possible to use different materials for the wheelhouse 14 and the front side member 24, and to use a different manufacturing method than the integrally molded member 25, such as extrusion molding.

[0071] Although one embodiment of the present invention has been described above, the present invention is not limited to these embodiments, and various modifications may be used in appropriate combinations with one embodiment, and of course, the invention can be implemented in various forms without departing from the spirit of the present invention.
