Technical Field
[0001] The invention relates to a vehicle front structure. Background Art
[0002] In recent years, the development of autonomous vehicles has been progressing. In such autonomous vehicles, an autonomous driving unit is mounted on the vehicle. In order not to reduce the space available to users due to the mounting of the autonomous driving unit, it is necessary to make plans.
[0003] For example, Japanese Patent Application Publication No. 2020-78985 proposes the following structure: by configuring an autonomous driving unit (autonomous driving equipment module) between the rear seat and the floor panel, the autonomous driving unit can be mounted on the vehicle without reducing the space available to the user. Summary of the invention
[0004] On the other hand, it is also necessary to protect the automatic driving unit in the event of a collision. In this regard, there is room for improvement in the above-mentioned mounting structure.
[0005] The present disclosure takes the above-mentioned facts into consideration, and aims to provide a vehicle front structure that does not reduce the space available to the user and has excellent protection performance for the automatic driving unit during a collision.
[0006] The vehicle front structure of the first scheme of the present disclosure comprises: a front panel, which divides a power unit room arranged on the lower side of the front of the vehicle and a vehicle room arranged on the upper side of the vehicle and the rear side of the vehicle of the power unit room; a partition wall, the lower end of which is fixed to the rear side end of the vehicle of the front panel, and extends from the lower end toward the upper side of the vehicle to divide the vehicle room into a front part and a rear part; a front vehicle seat arranged above the vehicle of the front panel; a seat support member, which supports the front vehicle seat from the lower side of the vehicle, and has a front end fixed to the front panel and a rear end fixed to the partition wall; and an automatic driving unit, at least a part of which is arranged in an area surrounded by the front panel, the partition wall and the seat support member to control the automatic driving of the vehicle.
[0007] A seat support member for supporting a front vehicle seat arranged above a dash panel that divides a power unit room provided at the lower side of the front of the vehicle and a vehicle room provided at the upper side of the power unit room and the rear side of the vehicle has its front end fixed to the dash panel and its rear end fixed to a partition wall that divides the front and rear parts of the vehicle room. In addition, a lower end of the partition wall is fixed to an end of the dash panel on the rear side of the vehicle.
[0008] At least a part of the automatic driving unit is disposed in a region surrounded by the dash panel, the seat support member, and the partition wall.
[0009] Thus, the automatic driving unit is arranged below the seat support member of the front vehicle seat in the front part of the vehicle cabin divided into the front and rear parts by the partition wall, so that it can be installed in the vehicle without reducing the space available to the vehicle user.
[0010] Furthermore, since at least a portion of the automatic driving unit is disposed in a region surrounded by the dash panel, the seat support member, and the partition wall, the automatic driving unit is excellently protected during a frontal collision of the vehicle.
[0011] In a vehicle front structure according to a second aspect of the present disclosure, in the vehicle front structure according to the first aspect, an upper end portion of the partition wall is fixed to a roof panel.
[0012] Since the upper end of the partition wall whose lower end is fixed to the dash panel is fixed to the roof panel, the strength of the partition wall is improved, and the protection performance of the automatic driving unit during a frontal collision of the vehicle is further improved.
[0013] In a vehicle front structure according to a third aspect of the present disclosure, in the vehicle front structure according to the first aspect or the second aspect, the vehicle front structure further includes a bracket mounted on the dash panel, and the automatic driving unit is supported by the bracket.
[0014] In this vehicle front structure, the automatic driving unit is supported and arranged on a bracket mounted on the dash panel. Therefore, compared with a case where the automatic driving unit is directly mounted on the dash panel, vibration of the automatic driving unit caused by road surface input is suppressed.
[0015] In the vehicle front structure of the fourth scheme of the present disclosure, in the vehicle front structure described in any one of the first scheme to the third scheme, it is also provided with: a front panel reinforcement, which connects the vehicle frame components extending in the vehicle front and rear directions on both sides of the vehicle width direction in the vehicle width direction and supports the vehicle front side end of the front panel; and a pressing member, which extends in the vehicle front and rear directions, with the front end fixed to the front panel reinforcement and the rear end fixed to the automatic driving unit.
[0016] In this vehicle front structure, a dash reinforcement and an automatic driving unit connected in the vehicle width direction between frame members extending in the vehicle longitudinal direction on both sides of the vehicle width direction are connected by a pressing member extending in the vehicle longitudinal direction.
[0017] Therefore, when a head-on collision occurs on the vehicle, the automatic driving unit is suppressed from being displaced forward of the vehicle by the pressing member, and the protection performance of the automatic driving unit is further improved.
[0018] In a vehicle front structure according to a fifth aspect of the present disclosure, in the vehicle front structure according to any one of the first to fourth aspects, the dash panel is inclined downward from the vehicle front side toward the vehicle rear side.
[0019] In the vehicle front structure of the fifth aspect, since the dash panel is inclined downward from the vehicle front side toward the vehicle rear side, a large space for arranging the automatic driving unit can be ensured.
[0020] In the vehicle front structure of the sixth aspect of the present disclosure, in the vehicle front structure described in the third aspect, the front end of the bracket is mounted to the middle position of the dash panel in the vehicle front and rear direction, and the rear end of the bracket is mounted to the vehicle rear side end of the dash panel.
[0021] In the vehicle front structure of the sixth embodiment, the automatic driving unit is arranged on a bracket mounted on the front and rear middle position of the dash panel and the rear end of the vehicle. Therefore, compared with the case where the automatic driving unit is directly mounted on the dash panel, the vibration caused by the road input is suppressed.
[0022] As described above, according to the vehicle front structure of the present disclosure, the space available to the user is not reduced and the automatic driving unit is excellently protected during a collision. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 3 It is a plan view showing the arrangement of a bracket and abutment bars for supporting an ADK at the front portion of the vehicle. DETAILED DESCRIPTION
[0027] Regarding the vehicle front structure of one embodiment, refer to Figure 1 to Figure 3 It should be noted that in each figure, arrows FR, LH, and UP respectively indicate the front of the vehicle (travel direction), the left of the vehicle, and the top of the vehicle. In the following, unless otherwise specified, when only the front and rear, left and right, and up and down directions are used for explanation, they indicate the front and back of the vehicle's front and rear direction, the left and right of the vehicle's left and right direction, and the up and down of the vehicle's up and down direction. Figure 2 In the figure, the floor panel 44 is omitted for convenience of explanation.
[0028] like Figure 1 and Figure 2As shown, a vehicle 12 to which the vehicle front structure 10 of the present embodiment is applied is a so-called frame vehicle in which a vehicle body 40 is supported by a ladder frame 14 , and is a bus as an example.
[0029] The vehicle body 40 of the vehicle 12 has a substantially rectangular parallelepiped shape. The vehicle 12 is, for example, an electric car.
[0030] First, the framework structure of the vehicle 12 will be described.
[0031] like Figure 1 and Figure 2 As shown, the trapezoidal frame 14 includes a pair of left and right side frames 16 and a plurality of cross beams 22, 24. The left and right side frames 16 extend in the front-rear direction at both sides of the vehicle 12 in the vehicle width direction. The plurality of cross beams 22, 24 are arranged at intervals in the front-rear direction and extend in the vehicle width direction. The left and right side frames 16 are connected by the plurality of cross beams 22, 24.
[0032] like Figure 1 As shown, each side frame 16 is composed of a front side frame 18, a center side frame 20, and a rear side frame (not shown).
[0033] The left and right front side frames 18 extend in the front-to-back direction at both sides of the front portion of the vehicle 12 in the vehicle width direction. The left and right center side frames 20 extend in the front-to-back direction at both sides of the center portion of the vehicle 12 in the vehicle width direction. The left and right rear side frames extend in the front-to-back direction at both sides of the rear portion of the vehicle 12 in the vehicle width direction. The front side frame 18, the center side frame 20, and the rear side frame are formed into a square tube shape, for example, from steel, and have a closed cross section when viewed from the front-to-back direction. It should be noted that a plurality of cross beams, not shown in the figure, are also provided between the left and right center side frames 20 and between the left and right rear side frames.
[0034] The front portion 18F of the left and right front side frames 18 extends linearly in the front-to-back direction. The front end portion of each front portion 18F (the front end portion of each front side frame 18) is provided as a deformation portion 18F1 that is axially compressed and deformed in the front-to-back direction when the vehicle 12 is subjected to a head-on collision. On the left and right side surfaces of each deformation portion 18F1, a plurality of reinforcing ribs 19 extending in the up-down direction are arranged in the front-to-back direction as an example. Thus, each deformation portion 18F1 is more fragile with respect to the load in the front-to-back direction than other portions of each front portion 18F. The middle portions in the front-to-back direction of each front portion 18F are connected in the vehicle width direction by a cross beam 22.
[0035] In the rear portion 18R of the left and right front side frames 18, the front side portion is set as a beam frame bent portion 18R1 that becomes a downslope from the front side to the rear side, and the rear side portion extends linearly in the front-to-rear direction. Each rear portion 18R is bent into a substantially crank shape at the bent portions 181 and 182 on the front and rear sides of the beam frame bent portion 18R1. The bent portion 181 on the front side is bent so as to bulge toward the upper side and the rear side, and the bent portion 182 on the rear side is bent so as to bulge toward the lower side and the front side. The front portions of the left and right beam frame bent portions 18R1 (i.e., the front portions of each rear portion 18R) are connected in the vehicle width direction by a cross beam 24. The front end portions of the left and right central side frames 20 are connected to the rear end portions of each rear portion 18R.
[0036] An electric motor 32 for driving the vehicle 12 is disposed between the left and right front side frames 18. The electric motor 32 is supported by the left and right front side frames 18 via the cross beams 22, 24, a support member (not shown), and the like. An electronic unit 34 for controlling the power supplied to the electric motor 32 is disposed above the electric motor 32. The electronic unit 34 is supported by the left and right front side frames 18 via a support frame 36. The electric motor 32 and the electronic unit 34 constitute a power unit.
[0037] The vehicle body 40 supported from below by the ladder frame 14 has a floor panel 44 constituting a floor portion of a vehicle cabin 42. The floor panel 44 includes a front floor panel 46 constituting a floor portion of the front portion of the vehicle cabin 42, a center floor panel 47 constituting a floor portion of a middle portion in the front-rear direction of the vehicle cabin 42, and a rear floor panel (not shown) constituting a floor portion of the rear portion of the vehicle cabin 42. The front floor panel 46, the center floor panel 47, and the rear floor panel are formed of, for example, steel plates.
[0038] It should be noted that the area below the front floor panel 46 where the electric motor 32 and the electronic unit 34 are disposed is the power unit room 38 .
[0039] The front portion of the front floor panel 46 is provided as a driver's seat floor portion 46F extending in the front-rear direction and the vehicle width direction. The rear portion of the front floor panel 46 is provided as an inclined portion 46R inclined downwardly toward the vehicle rear side.
[0040] The driver's seat floor portion 46F is arranged to be separated from the front portion 18F of the left and right front side frames 18 to the upper side, and the inclined portion 46R is arranged to be separated from the rear portion 18R of the left and right front side frames 18 to the upper side. The electronic unit 34 is arranged below the driver's seat floor portion 46F. The front end portion of the inclined portion 46R is joined to the seat cross beam 62 described later. In other words, the front end portion of the inclined portion 46R is supported by the seat cross beam 62. On the other hand, the rear end portion of the inclined portion 46R is connected to the front end portion of the center floor panel 47.
[0041] The center floor panel 47 extends in the front-rear direction and the vehicle width direction. A battery (not shown) for storing electric power to be supplied to the above-mentioned electric motor 32 is arranged below the center floor panel 47 .
[0042] The front floor panel 46 is supported by the left and right front side frames 18 via a pair of left and right front side members 48. The left and right front side members 48 extend in the front-rear direction above and outside the left and right front side frames 18 in the vehicle width direction. The front side members 48 correspond to "vehicle frame members".
[0043] The left and right front side members 48 are manufactured by, for example, press-forming a steel plate, and are joined to the lower surface of the front floor panel 46 by welding or the like.
[0044] The front portion 48F of the left and right front longitudinal beams 48 extends linearly in the front-to-rear direction and is joined to the lower surface of the driver's seat floor portion 46F of the front floor panel 46. The rear portion 48R of the left and right front longitudinal beams 48 (hereinafter, sometimes referred to as "beam frame bent portion 48R") is provided as a beam frame bent portion inclined downwardly toward the rear side of the vehicle and is joined to the lower surface of the inclined portion 46R of the front floor panel 46. Each beam frame bent portion 48R is bent into a substantially crank shape at bent portions 481 and 482 on both the front and rear sides. The bent portion 481 on the front side is bent so as to bulge upward and toward the rear side, and the bent portion 482 on the rear side is bent so as to bulge downward and toward the front side.
[0045] A front cross member 50 extending in the vehicle width direction is disposed at the front end portions of the left and right front longitudinal beams 48. The front cross member 50 is formed of, for example, a steel plate, and has a top-hat-shaped cross section that opens toward the front side when viewed from the vehicle width direction. A flange portion that overlaps the rear surface of the front cross member 50 is provided at the front end portions of the left and right front longitudinal beams 48, for example, and the flange portion is fixed to the rear surface of the front cross member 50 by bolt fastening or the like. Thus, the front end portions of the left and right front longitudinal beams 48 are connected in the vehicle width direction by the front cross member 50.
[0046] Both ends of the front cross member 50 in the vehicle width direction are supported by front ends of the left and right front side frames 18 (ie, the deformation portions 18F1 ) via left and right front side pillar members 52 . The lower ends of the front side pillar members 52 are fixed to the front side frames 18 via brackets 54 .
[0047] The front lower end of each beam bent portion 48R in the left and right front longitudinal beams 48 is supported by the left and right front side frames 18 via the left and right rear side pillar members 56. In each rear side pillar member 56, for example, a flange portion formed at the upper end is fixed to the front end of each beam bent portion 48R by welding or other means. The lower end of each rear side pillar member 56 is fixed to the front side frame 18 via a bracket not shown.
[0048] The left and right front longitudinal beams 48 are supported from below by the front side frames 18 via the front cross beam 50, the front side pillar member 52, the bracket 54, the rear side pillar member 56 and the bracket (not shown). Furthermore, the front floor panel 46 is supported from below by the front longitudinal beams 48. An instrument panel 60 is mounted and fixed on the upper surface of the front portion of the front floor panel 46.
[0049] The front upper end portions of the beam frame bent portions 48R of the left and right front longitudinal beams 48 are connected in the vehicle width direction by a seat cross beam 62. The seat cross beam 62 is formed into a square tube shape, for example, from steel, and extends in the vehicle width direction. Both ends of the seat cross beam 62 in the vehicle width direction are connected to the front upper end portions of the beam frame bent portions 48R by welding or other means. The rear end portion of the driver's seat floor portion 46F is connected to the upper surface of the seat cross beam 62 by welding or other means. In addition, the seat cross beam 62 supports the front end portion of the seat frame 64 from the lower side.
[0050] It should be noted that the seat cross member 62 corresponds to a "dash panel reinforcement".
[0051] The seat frame 64 is a frame that supports a driver's seat 66, which is a seat of the vehicle 12, from below. The seat frame 64 corresponds to a "seat support member." The driver's seat 66 corresponds to a "front vehicle seat."
[0052] The seat frame 64 includes a pair of left and right vertical portions 641 extending in the vertical direction and a horizontal portion 642 extending rearward from the upper ends of the left and right vertical portions 641. An oblique column portion 643 is provided between the lower end of the vertical portion 641 and the middle portion in the front-rear direction of the horizontal portion 642 in an oblique column shape. The lower end of the vertical portion 641 is fixed to the rear end of the driver's seat floor portion 46F and the seat cross beam 62 by bolt fastening or the like. The rear end of the horizontal portion 642 is fixed to a cross beam 72 (described later) mounted in the middle portion in the vertical direction of a pair of left and right pillars 68, which are erected at the front end of the center floor panel 47.
[0053] The left and right pillars 68 are formed into a square tube shape, for example, from steel, extending in the vertical direction and arranged at intervals in the vehicle width direction. A plurality of passenger seats 70 are arranged on the rear side of the left and right pillars 68. The plurality of passenger seats 70 are arranged in the vehicle width direction and fixed to the left and right pillars 68 via brackets or the like. It should be noted that, although not shown in the figure, a plurality of passenger seats not shown in the figure are also provided in the rear part of the vehicle compartment 42.
[0054] It should be noted that a plurality of cross beams (only the cross beam 72 is shown as an example) are mounted on the left and right pillars 68 at predetermined intervals in the vertical direction. The left and right pillars 68 and the plurality of cross beams constitute a partition wall 74 that partitions the driver's seat 66 (the front part of the vehicle compartment 42) and the passenger seat 70 (the rear part of the vehicle compartment 42).
[0055] The cross member 72 is formed of a steel material into a square tube shape, for example, and extends in the vehicle width direction. The rear end of the horizontal portion 642 of the seat frame 64 is joined. That is, the rear end of the seat frame 64 is fixed to the support column 68 (partition wall 74) via the cross member 72.
[0056] It should be noted that, in the present embodiment, the partition wall 74 is constructed using a pair of pillars 68 extending in the vertical direction of the vehicle, a plurality of cross beams including a cross beam 72 installed on the pair of pillars 68 and extending in the vehicle width direction (other cross beams are omitted in the illustration), and panels not shown installed on both sides of a frame member formed by cross beams such as the pillars 68 and the cross beam 72. However, it can also be formed using only a frame member with the panel omitted, or it can be a partition wall formed by a single steel plate.
[0057] The support column 68 is fastened to the floor panel 44 (the front end portion of the center floor panel 47 ) at a mounting portion 80 at the lower end, and is fastened to the roof panel 84 at a mounting portion 82 at the upper end.
[0058] It should be noted that the rear end portion of the floor panel 44 extending from the driver's seat floor portion 46F (including at least the portion joined to the seat cross member 62) (see Figure 1 , position D1) through the inclined portion 46R to the front end portion of the center floor panel 47 (including at least the fastening portion of the mounting portion 80 of the support 68) (refer to Figure 1 Hereinafter, the floor panel 44 in this range (the range from position D1 to position D2) may be referred to as the "dash panel 110".
[0059] In addition, on the inclined portion 46R of the front floor panel 46, as shown in FIG. Figure 3 As shown, the bracket 90 is L-shaped when viewed in the vehicle width direction (see Figure 1 ) are arranged with three pieces spaced apart at predetermined intervals in the vehicle width direction.
[0060] Each bracket 90 includes a horizontal portion 901 extending in the vehicle front-rear direction and a vertical portion 902 extending downward from the rear end of the horizontal portion 901. The front end of the horizontal portion 901 is fastened (fixed) to the step portion 92 of the inclined portion 46R via a flange portion 94. On the other hand, the lower end of the vertical portion 902 is fastened (fixed) to the front end portion of the center floor panel 47 via a flange portion 96. Thus, the bracket 90 is fixed to the inclined portion 46R (front panel 110) of the front floor panel 46.
[0061] An autonomous driving kit (ADK) 100 is mounted on the horizontal portion 901 of the three brackets 90. The ADK 100 has a substantially rectangular shape and is horizontally disposed on the dash panel 110 with its lower surface supported by the brackets 90 .
[0062] like Figure 2 As shown, ADK100 extends from the rear portion 18R of the left front side frame 18 in the vehicle width direction through the bottom of the seat frame 64 (driver's seat 66) to the vicinity of the beam bending portion 48R of the right front longitudinal beam 48. That is, a portion of ADK100 (the center portion in the vehicle width direction) is located below the seat frame 64.
[0063] In addition, the front surface 100F of the ADK 100 and the seat cross beam 62 are connected by a collision bar 102. The collision bar 102 extends in the front-rear direction, and its front end passes through the inclined portion 46R via a flange portion 104 and is fastened (fixed) to the rear surface of the seat cross beam 62. In addition, the rear end of the collision bar 102 is fixed to the front surface 100F of the ADK 100 via a flange portion 106. It should be noted that the collision bar 102 is equivalent to a "pressing member".
[0064] (effect)
[0065] Regarding the effect of the vehicle front structure 10 thus constructed, refer to Figure 1 to Figure 3 To explain.
[0066] In the vehicle front structure 10, as Figure 1 As shown in FIG. 1 , the ADK 100 disposed via the bracket 90 on the upper portion of the inclined portion 46R (front panel 110) of the front floor panel 46 is located below the seat frame 64 in the vehicle and in front of the partition wall 74 (pillar 68). That is, the ADK 100 (at least a portion thereof) is disposed in the area A (see FIG. 1 ) surrounded by the seat frame 64, the partition wall 74 (pillar 68), and the front panel 110, which are formed of, for example, a steel pipe or a steel plate. Figure 1 , Figure 2 Therefore, ADK100 has excellent protection performance during a frontal collision of the vehicle 12.
[0067] In particular, the front end portion (the lower end portion of the vertical portion 641) of the seat frame 64 is fixed to the front end portion of the dash panel 110, and the rear end portion (the rear end portion of the horizontal portion 642) is fixed to the pillar 68 (partition wall 74) via the cross member 72. In addition, the pillar 68 (partition wall 74) is fastened (fixed) to the rear end portion of the dash panel 110 via the mounting portion 80 at the lower end.
[0068] That is, the seat frame 64, the dash panel 110, and the partition wall 74 are connected (fixed) to form the region A, so the strength is high, and damage to the ADK 100 is prevented or suppressed regardless of the deformation of the front part of the vehicle during a frontal collision of the vehicle 12. That is, the protection performance of the ADK 100 of the vehicle front structure 10 is excellent.
[0069] It should be noted that since ADK100 is arranged in area A which serves as dead space, above the front panel 110, below the driver's seat 66 (seat frame 64) and in front of the partition wall 74 on the side of the vehicle interior 42 via the bracket 90, ADK100 can be arranged in the vehicle 12 without reducing the space available to users in the vehicle 12.
[0070] That is, in the vehicle front structure 10, the area A (see FIG. 1 ) surrounded by the seat frame 64, the partition wall 74 (pillar 68), and the dash panel 110 is formed. Figure 1 , Figure 2 By disposing the ADK 100 in the hatched area A) in the figure, the AKD 100 can be disposed in the vehicle 12 without reducing the space available to the user, and the ADK 100 has excellent protection performance in the event of a frontal collision of the vehicle 12 .
[0071] In addition, since a seat cross beam 62 extending in the vehicle width direction is joined below the front end portion of the front panel 110 to which the front end portion of the seat frame 64 (the lower end portion of the vertical portion 641) is fixed so as to connect the front longitudinal beams 48 extending in the vehicle front-rear direction on both sides of the vehicle, the supporting strength of the seat frame 64 and the front panel 110 is improved, and the protection performance of ADK100 is further improved.
[0072] Furthermore, the mounting portion 80 at the lower end of the pillar 68 constituting the partition wall 74 is fastened (fixed) to the front end portion of the center floor panel 47 of the floor panel 44 (the rear end portion of the dash panel 110), and the mounting portion 82 at the upper end of the pillar 68 is fastened (fixed) to the roof panel 84. That is, the partition wall 74 (pillar 68) is fixed to the floor panel 44 (dash panel 110) and the roof panel 84, so that the strength of the partition wall 74 is further improved. That is, the protection performance of the ADK 100 during the frontal collision of the vehicle 12 is further improved.
[0073] Furthermore, the ADK 100 is disposed at a predetermined position in the region A via the bracket 90 attached to the inclined portion 46R (the dash panel 110 ). Therefore, compared with a case where the ADK 100 is directly attached to the dash panel 110 , vibration caused by road surface input is suppressed.
[0074] Furthermore, by providing the L-shaped bracket 90 relative to the inclined dash panel 110 (inclined portion 46R) in a side view of the vehicle, a horizontal portion 901 where the ADK 100 can be installed can be formed. That is, the ADK 100 can be installed horizontally in the region A by using the bracket 90 .
[0075] Furthermore, since the support rod 102 extending in the front-rear direction is provided between the front surface 100F of the rectangular ADK 100 and the rear surface side of the square tube-shaped seat cross member 62, the ADK 100 can be prevented or suppressed from moving forward during a frontal collision of the vehicle.
