Description

[Technical Field]

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

[0002] In a vehicle (automobile), a radiator core for cooling the vehicle's power unit and the like is provided at the front end of the vehicle (see Patent Document 1 below). The radiator core is arranged along the vertical direction of the vehicle when viewed in the vehicle width direction. The radiator core is usually arranged between a pair of left and right front side frames and connected to the pair of front side frames by radiator supports that support the radiator core. In other words, the pair of left and right front side frames are connected by the radiator core and the radiator supports.

[0003] Here, by arranging the radiator core so that it is tilted toward the rear of the vehicle as it approaches the upper side of the vehicle when viewed from the vehicle width direction, it is possible to reduce the installation space for the radiator core in the vertical direction. As a result, the space above the radiator core can be utilized to provide, for example, a trunk or the like in the front part of the vehicle. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2023-101999 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in a structure in which the radiator core is disposed at an angle, for example, the radiator core is mounted on the vehicle frame or the like, eliminating the need for a conventional radiator support. In other words, the pair of left and right front side frames are not connected by the radiator core and radiator support. This may result in a decrease in rigidity at the front of the vehicle.

[0006] SUMMARY OF THE INVENTION In consideration of the above, an object of the present invention is to provide a vehicle front structure that can increase the rigidity of the vehicle front while arranging a radiator core obliquely. [Means for solving the problem]

[0007] One or more embodiments of the present invention are a vehicle front structure comprising a pair of front side frames extending in the fore-and-aft direction of the vehicle on both sides of the front of the vehicle in the vehicle width direction, a radiator core arranged between the pair of front side frames and inclined toward the rear of the vehicle as it approaches the upper side of the vehicle when viewed in the vehicle width direction, and a first cross member extending in the vehicle width direction and spanning the pair of front side frames above the radiator core. [Effects of the Invention]

[0008] According to one or more embodiments of the present invention, the rigidity of the front part of the vehicle can be increased while the radiator core is disposed obliquely. [Brief explanation of the drawings]

[0010] Hereinafter, a vehicle (automobile) V to which a vehicle front structure S according to this embodiment is applied will be described with reference to the drawings. In the drawings, the front side of the vehicle V is indicated by an arrow FR, the upper side of the vehicle is indicated by an arrow UP, and the left side of the vehicle (one side in the vehicle width direction) when viewed from above the vehicle is indicated by an arrow LH. In addition, in the following description, when the up-down, front-rear, and left-right directions are used, they refer to the up-down direction of the vehicle, the front-rear direction of the vehicle, and the left-right direction of the vehicle unless otherwise specified.

[0011] As shown in Figures 1 and 2, a vehicle front structure S is applied to the front of a vehicle V. The vehicle front structure S is configured to include a pair of left and right front side frames 10, a bumper beam 16, a subframe 18, and a radiator core 20. The vehicle front structure S also has a first cross member 30 and a second cross member 40. Furthermore, the vehicle front structure S has a gusset mechanism 50, and the front side frames 10 and the first cross member 30 are connected using the gusset mechanism 50. Each component of the vehicle front structure S will be described below.

[0012] The pair of front side frames 10 are formed in the shape of hollow, approximately rectangular pillars extending in the front-to-rear direction, and are arranged on both sides in the vehicle width direction (on both sides in the left-to-right direction) of a power unit compartment 12 at the front of the vehicle V. Crash boxes 14 are provided in front of the front side frames 10. The crash boxes 14 are formed in the shape of approximately rectangular cylinders with their axial directions extending in the front-to-rear direction, and the rear ends of the crash boxes 14 are connected to the front ends of the front side frames 10.

[0013] The bumper beam 16 extends in the vehicle width direction and forms a framework at the front end of the vehicle V. The bumper beam 16 is formed in a substantially rectangular frame shape in a cross section seen from the longitudinal direction of the bumper beam 16. That is, the bumper beam 16 has a rectangular closed cross-sectional structure. The bumper beam 16 is connected to the front end portions of the crash boxes 14 with both end portions of the bumper beam 16 in the vehicle width direction protruding outward in the vehicle width direction beyond the front side frames 10. In this way, the bumper beam 16 is connected to the front side frames 10 via the crash boxes 14. Note that the crash boxes 14 may be omitted and the bumper beam 16 may be directly connected to the front end portions of the front side frames 10.

[0014] The subframe 18 is provided below the front side frames 10 and constitutes the lower end of the framework at the front of the vehicle V. The subframe 18 is formed in a generally rectangular ring shape in a plan view. Specifically, the subframe 18 has a pair of left and right subframe side portions 18A and a subframe front portion 18B spanning the front ends of the subframe side portions 18A. The subframe side portions 18A are formed in a generally hollow columnar shape extending in the front-rear direction and are connected to the front side frame 10 by brackets (not shown). The front ends of the subframe side portions 18A are bent in a generally crank-like shape that protrudes upward when viewed from the left and right. That is, the front ends of the subframe side portions 18A are provided with an inclined portion 18A1 that slopes upward toward the front and a protruding portion 18A2 that protrudes upward from the front end of the inclined portion 18A1. The subframe front portion 18B extends in the left-right direction and spans the protruding portion 18A2.

[0015] The radiator core 20 is a cooling device for cooling a power unit (not shown) of the vehicle V and the like. The radiator core 20 is formed in a generally rectangular, flat shape overall and is disposed between the front ends of a pair of left and right front side frames 10 in a rearwardly tilted state. Specifically, the radiator core 20 tilts rearward as it extends upward in a side view. In the following description, the extending direction of the radiator core 20 in a side view is referred to as the tilt direction (see arrows A and B in FIG. 2). A lower end (front end) of the radiator core 20 is supported from below by a subframe front portion 18B of the subframe 18 via a mount member (not shown). An upper end portion (rear end portion) of the radiator core 20 is supported from below by a lower frame 42 of a second cross member 40 (described later) via a mount member (not shown).

[0016] The first cross member 30 is formed in a hollow, generally rectangular pillar shape extending in the vehicle width direction. The first cross member 30 is disposed adjacent to the upper side of the front side frame 10, and both longitudinal end portions of the first cross member 30 are connected to the front side frame 10 by gusset mechanisms 50 (described later).

[0017] 3, both longitudinal ends of the first cross member 30 protrude outward in the vehicle width direction beyond the front side frames 10. Outer connecting portions 31 are provided at both longitudinal ends of the first cross member 30. The outer connecting portions 31 are formed in a generally rectangular tubular shape with their axial direction extending in the up-down direction, and extend downward from the first cross member 30 outside the front side frames 10 in the vehicle width direction. The lower end of the outer connecting portion 31 is located below the front side frames 10, and is joined to the upper wall of the rear end of the overhanging portion 18A2 of the subframe 18 by welding or the like.

[0018] Additionally, inner connecting portions 32 are provided on both longitudinal end portions of the first cross member 30. The inner connecting portions 32 are formed in a generally rectangular tubular shape with the axial direction extending in the up-down direction, and extend downward from the first cross member 30 on the inner side of the front side frame 10 in the vehicle width direction. The lower end of the inner connecting portion 32 is located below the front side frame 10, and is joined to the upper wall of the subframe front portion 18B of the subframe 18 by welding or the like.

[0019] The first cross member 30 is located above the lower end portion of the radiator core 20 and is located in front of the upper part of the radiator core 20. In other words, the first cross member 30 is located below the upper end of the radiator core 20, and the first cross member 30 overlaps with the radiator core 20 in both a front view and a plan view. In addition, a lower rear corner of the first cross member 30 is located above and in close proximity to the front of the vertical middle portion of the radiator core 20.

[0020] The second cross member 40 is formed in a generally rectangular annular shape with its longitudinal direction aligned with the vehicle width direction in a front view. The second cross member 40 is disposed rearward of the first cross member 30 and above the front side frames 10. Both longitudinal ends of the second cross member 40 are joined to strut towers 22 provided on both the left and right sides of the power unit compartment 12. In other words, the second cross member 40 connects the pair of left and right strut towers 22.

[0021] The second cross member 40 includes an upper frame 41 extending in the vehicle width direction, a lower frame 42 extending in the vehicle width direction at a position lower than the upper frame 41, and a pair of left and right connecting frames 43 connecting the longitudinal outer ends of the upper frame 41 and the lower frame 42. The upper frame 41 and the lower frame 42 are formed as hollow, generally rectangular pillars extending in the left-right direction, with the front-rear length of the upper frame 41 being longer than the front-rear length of the lower frame 42. The upper frame 41 is disposed diagonally rearward above the lower frame 42. The connecting frame 43 is formed as a hollow, generally pillar-like pillar extending in the vertical direction, and is inclined rearward as it extends upward in a side view. The front-rear length of the connecting frame 43 is configured to increase as it extends upward. The upper end of the connecting frame 43 is joined to the lower surface of the upper frame 41, and the lower end of the connecting frame 43 is joined to the upper surface of the lower frame 42.

[0022] The front end of the lower wall of the upper frame 41 serves as a radiator receiving portion 41A. The radiator receiving portion 41A is located on one side in the oblique direction (the side indicated by arrow A in FIG. 2 ) of the upper end of the radiator core 20. That is, the upper frame 41 is located above and rearward of the upper end of the radiator core 20. An inverter unit 24, serving as an electric device, is provided on the upper rear side of the upper frame 41. The inverter unit 24 is disposed above the power unit compartment 12. That is, the inverter unit 24 is located on one side in the oblique direction (upper and rearward) of the radiator core 20 and above the first cross member 30. The front end of the inverter unit 24 is supported from below by the rear end of the upper frame 41 via a pair of left and right mount members 25. The rear end of the inverter unit 24 is connected to the vehicle body by a bracket (not shown).

[0023] The lower frame 42 is disposed below the upper part of the radiator core 20. In other words, the lower frame 42 is located above the middle part in the front-rear direction of the radiator core 20. The upper part of the radiator core 20 is supported from below by the lower frame 42 via a mounting member (not shown).

[0024] A trunk room 26 is provided at the front end of the power unit compartment 12 of the vehicle V. The trunk room 26 is formed in a recessed shape that is open upward, and is disposed above the radiator core 20 and in front of the inverter device 24. A hood 28 is also provided at the front of the vehicle V. The hood 28 is formed in the shape of a substantially rectangular panel with its thickness direction extending in the up-down direction, and is provided at the front of the vehicle V in a state in which the power unit compartment 12 of the vehicle V is closed from above.

[0025] 1 to 4, the gusset mechanism 50 is applied to the joining between the left and right front side frames 10 and the first cross member 30. Below, the configuration of the gusset mechanism 50 will be described using the gusset mechanism 50 used to join the right front side frame 10 and the first cross member 30.

[0026] The gusset mechanism 50 has a pair of left and right gussets 51A, 51B, which are configured symmetrically. Therefore, the configuration of the gussets 51A, 51B will be described using the left (vehicle widthwise center) gusset 51A. The gusset 51A is made of a metal plate and is formed in a generally elongated plate shape extending in the front-to-rear direction. The gusset 51A is bent in a generally inverted L shape in a front view. Specifically, the gusset 51A includes an upper wall 52 whose plate thickness direction is the up-down direction and a side wall 53 extending downward from the left end of the upper wall 52. The gusset 51A is disposed between the front side frame 10 and the first cross member 30 so as to cover the upper left corner of the front side frame 10. Specifically, the upper wall 52 of the gusset 51A is sandwiched between the upper wall of the front side frame 10 and the lower wall of the first cross member 30, and the side wall 53 of the gusset 51A is disposed adjacent to the left side of the front side frame 10. As a result, the gusset 51A extends in the front-to-rear direction along the ridge line of the corner of the front side frame 10.

[0027] The upper wall of the front side frame 10, the upper wall 52 of the gusset 51A, and the lower wall of the first cross member 30 are joined by spot welding at multiple locations (four locations in this embodiment). Specifically, multiple joints 54 joining the front side frame 10, the upper wall 52 of the gusset 51A, and the lower wall of the first cross member 30 are arranged side by side in the vehicle fore-and-aft direction.

[0028] Furthermore, the left side wall of the front side frame 10 and the side wall 53 of the gusset 51A are joined by spot welding at multiple locations (four locations in this embodiment). Specifically, multiple joints 55 joining the left side wall of the front side frame 10 and the side wall 53 of the gusset 51A are arranged side by side in the vehicle longitudinal direction.

[0029] When the gusset 51A is joined to the front side frame 10, the front end of the gusset 51A protrudes forward beyond the first cross member 30. A flange portion 56 is formed at the front end of the gusset 51A. In a front view, the flange portion 56 is bent toward the opposite side from the front side frame 10 at the front ends of the top wall 52 and the side wall 53 of the gusset 51A. That is, in a front view, the flange portion 56 is formed in a substantially inverted L-shaped plate shape with the plate thickness direction extending in the front-to-rear direction, and is connected to the front ends of the top wall 52 and the side wall 53. The flange portion 56 is located rearward of the crash box 14.

[0030] As will be described in more detail later, in the event of a frontal collision of the vehicle V, the joints 54, 55 between the gussets 51A, 51B and the front side frame 10 are broken, and the joint between the first cross member 30 and the front side frame 10 is released.

[0031] (Action and effect) Next, the behavior of the front part of the vehicle V in a frontal collision and a small wrap collision of the vehicle V will be explained, and the operation and effect of this embodiment will be explained.

[0032] In a frontal collision of the vehicle V, a collision object BL collides with the front end of the vehicle V. As a result, a collision load toward the rear of the vehicle is input to the bumper beam 16, and the crash boxes 14 are compressively deformed by the collision load. As a result, the crash boxes 14 absorb the collision load. As the collision object BL further intrudes rearward, the front ends of the crash boxes 14 and the front side frames 10 are compressively deformed and collide with the flange portions 56 of the gussets 51A and 51B. As a result, the collision load toward the rear is input to the flange portions 56. As a result, the gussets 51A and 51B are deformed so as to be turned up relative to the front side frame 10 (see the arrows in FIG. 3), and the joints 54 and 55 between the gussets 51A and 51B and the front side frame 10 are broken in order from the front side. As a result, the first cross member 30 is no longer joined to the front side frame 10.

[0033] At this time, a rearward collision load is applied to the front end of the subframe 18, causing the front end of the subframe side portion 18A of the subframe 18 to bend upward in a crank shape. As a result, the front end of the subframe 18 is bent at the bent portion and deformed rearward and upward. Furthermore, both longitudinal ends of the first cross member 30 are connected to the front end of the subframe 18 by the outer connecting portion 31 and the inner connecting portion 32. As a result, a load acts on the first cross member 30 from the subframe 18 diagonally upward and rearward. Therefore, the load input from the subframe 18 to the first cross member 30 promotes fracture of the joints 54, 55 between the gussets 51A, 51B and the front side frame 10.

[0034] Furthermore, when a colliding object BL enters the power unit compartment 12, the lower end (front end) of the radiator core 20 moves backward together with the front end of the sub-frame 18. That is, a rearward collision load is input to the lower end of the radiator core 20. Here, the lower frame 42 of the second cross member 40 is positioned rearward of the upper part of the radiator core 20 and supports the radiator core 20 from below. Therefore, the radiator core 20 is guided by the lower frame 42 to move backward toward one side in the oblique direction (toward the radiator receiving portion 41A of the upper frame 41). More specifically, the radiator core 20 moves backward toward one side in the oblique direction while the angle of inclination of the radiator core 20 with respect to the front-to-rear direction gradually increases. As a result, as shown in FIG. 5 , the upper end of the radiator core 20 collides with the radiator receiving portion 41A of the upper frame 41 of the second cross member 40, and the radiator core 20 moving backward toward one side in the oblique direction is received by the radiator receiving portion 41A. As a result, the second cross member 40 prevents the radiator core 20 from moving toward the inverter device 24 side.

[0035] Furthermore, when the retreating radiator core 20 is received by the radiator receiving portion 41A, a reaction force from the upper frame 41 of the second cross member 40 toward the other side in the inclination direction acts on the upper end of the radiator core 20. Meanwhile, as described above, a collision load from the colliding object BL toward the rear acts on the lower end of the radiator core 20. Therefore, the radiator core 20 is sandwiched from both front-rear directions between the colliding object BL and the second cross member 40, and is crushed in the front-rear direction.

[0036] Then, as shown in FIG. 6 , the first cross member 30, which has been released from its connection with the front side frame 10, moves rearward and collides with the vertically middle portion of the radiator core 20. Also, as described above, the lower frame 42 of the second cross member 40 is located rearward of the rear end portion of the radiator core 20. Therefore, when the radiator core 20 collapses in the longitudinal direction, the vertically middle portion of the radiator core 20 is sandwiched between the first cross member 30 and the second cross member 40 in the longitudinal direction. This causes the radiator core 20 to bend at a position below the inverter unit 24. Therefore, the collision of the radiator core 20 with the inverter unit 24 after the collapse is suppressed.

[0037] In a small lap collision of the vehicle V, the collision object BL collides with the front end of the vehicle V on the outer side of the front side frame 10 in the vehicle width direction. As a result, the collision object BL collides with the front end of the subframe 18. As a result, a reaction force is applied from the subframe 18 to the collision object BL.

[0038] Furthermore, outer coupling portions 31 are provided on the outer sides of the front side frames 10 in the vehicle width direction, and the first cross member 30 and the subframe 18 are coupled by the outer coupling portions 31. Therefore, if the collision object BL intrudes further rearward, the collision object BL collides with the outer coupling portion 31 and the first cross member 30, and a reaction force acts on the collision object BL from the outer coupling portion 31 and the first cross member 30. As described above, in the event of a small lap collision of the vehicle V, the reaction force acts effectively on the collision object BL from the subframe 18, outer coupling portion 31, and first cross member 30, and the rearward intrusion of the collision object BL can be suppressed by the subframe 18, outer coupling portion 31, and first cross member 30.

[0039] Here, in the vehicle V, the radiator core 20 is provided between the front side frames 10 at the front end of the power unit compartment 12, and is inclined rearward as it extends upward in a side view. This reduces the installation space for the radiator core 20 in the vertical direction. Therefore, space for installing a trunk room 26 can be effectively secured at the front end of the power unit compartment 12. In addition, a first cross member 30 extending in the vehicle width direction is provided in the power unit compartment 12. The first cross member 30 is disposed above the radiator core 20 and bridges the front side frames 10. As a result, the front end portions of the pair of left and right front side frames 10 are connected by the first cross member 30. Therefore, even when the radiator core 20 is inclined rearward, the rigidity of the front end of the vehicle V can be increased, which ultimately contributes to the driving stability of the vehicle V.

[0040] In addition, the first cross member 30, which is bridged across the pair of left and right front side frames 10, is located above the radiator core 20. This allows the first cross member 30 to be positioned by effectively utilizing the space above the radiator core 20, which is positioned at an angle. This allows the installation space for the first cross member 30 and the radiator core 20 to be made more compact.

[0041] Additionally, a second cross member 40 extending in the vehicle width direction is provided behind the first cross member 30, and both longitudinal ends of the second cross member 40 are joined to the strut towers 22. Therefore, the pair of left and right strut towers 22 can be connected by the second cross member 40. This further increases the rigidity of the front of the vehicle V and effectively improves the driving stability of the vehicle V.

[0042] Furthermore, the inverter device 24 is provided on one side (rear and upper side) of the radiator core 20 in the tilt direction. Specifically, the upper frame 41 of the second cross member 40 is disposed between the radiator core 20 and the inverter device 24 in the tilt direction. In the event of a frontal collision of the vehicle V, the upper frame 41 receives the upper end of the radiator core 20 as it moves backward, thereby suppressing movement of the radiator core 20 toward the inverter device 24. As a result, even when the radiator core 20 is disposed so as to be tilted backward and the inverter device 24 is disposed behind the radiator core 20, the second cross member 40 can receive the radiator core 20 as it moves backward, thereby suppressing a direct collision of the radiator core 20 with the inverter device 24. Therefore, by utilizing the second cross member 40, which increases the rigidity of the front part of the vehicle V, the protection performance of the inverter device 24 can be improved.

[0043] Furthermore, the second cross member 40 is formed in a rectangular annular shape with its longitudinal direction aligned with the vehicle width direction in a front view. This increases the rigidity of the second cross member 40 itself. The second cross member 40 also has an upper frame 41 and a lower frame 42 that extend in the vehicle width direction. The upper frame 41 is positioned above the radiator core 20, and the lower frame 42 is positioned below the upper end portion (rear end portion) of the radiator core 20. During a frontal collision of the vehicle V, the lower frame 42 guides the retreating radiator core 20, causing the upper end of the radiator core 20 to approach the upper frame 41, and the upper frame 41 receives the approaching upper end of the radiator core 20. This allows the lower frame 42 to control the behavior of the retreating radiator core 20, allowing the upper end (rear end) of the radiator core 20 to collide with the upper frame 41.

[0044] Furthermore, the first cross member 30 is disposed below the upper end of the radiator core 20. More specifically, the first cross member 30 overlaps with the radiator core 20 in both a front view and a plan view. This allows the first cross member 30, which moves rearward during a frontal collision of the vehicle V, to collide with the vertical middle portion of the radiator core 20. Therefore, as described above, when the radiator core 20 collapses in the front-to-rear direction, the first cross member 30 and the second cross member 40 sandwich the vertical middle portion of the radiator core 20 in the front-to-rear direction, and the radiator core 20 can be bent at a position below the inverter device 24. Therefore, when the radiator core 20 collapses, movement of the radiator core 20 toward the inverter device 24 can be effectively suppressed.

[0045] In addition, the front end of the inverter device 24 is mounted at the rear end of the upper frame 41. Therefore, the inverter device 24 can be mounted by utilizing the second cross member 40, which contributes to improving the rigidity of the vehicle V and the protection performance of the inverter device 24. This contributes to cost reduction compared to a configuration in which a separate member for mounting the inverter device 24 is provided.

[0046] In this embodiment, the upper frame 41 of the second cross member 40 is formed as a hollow rectangular pillar, but the cross-sectional shape of the upper frame 41 can be modified as appropriate. For example, the lower front corners of the upper frame 41 may be chamfered, and the chamfered portions may serve as the radiator receiving portion 41A. In this case, the lower surface of the radiator receiving portion 41A is positioned to face the upper end portion of the radiator core 20 in the oblique direction. Therefore, when the radiator core 20 collides with the radiator receiving portion 41A, the radiator core 20 can be properly received by the radiator receiving portion 41A.

[0047] In addition, in this embodiment, the first cross member 30 is connected to the subframe 18 by the outer connecting portion 31 and the inner connecting portion 32, but the outer connecting portion 31 and the inner connecting portion 32 may be omitted to release the connection between the first cross member 30 and the subframe 18.
