[0004] PATENT LITERATURE

[0005] Patent Literature 1: Japanese Patent Application Publication No. 2021-035789 SUMMARY

[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] However, in an automobile, how to ensure the rigidity of the vehicle body becomes an important issue. In this regard, for example, it can be considered to provide a reinforcing member or the like inside the passenger compartment, but other components and devices or the like are also provided inside the passenger compartment, and it is difficult to improve the rigidity of the vehicle body while improving the layout freedom of them.

[0008] The present disclosure is made in view of the above circumstances, and aims to improve the layout freedom inside the passenger compartment while improving the rigidity of the vehicle body.

[0009] SOLUTION TO PROBLEM

[0010] To achieve the foregoing object, a first aspect of the present disclosure provides a vehicle body structure of an automobile. The vehicle body structure includes: a floor panel that constitutes a floor of a passenger compartment provided with a seat on which an occupant sits; a center tunnel that extends in a vehicle longitudinal direction and is provided so as to be separated upward from the floor panel at a central portion in a vehicle width direction of the passenger compartment; and an air conditioning device that blows air conditioning air to the passenger compartment. The air conditioning device includes: a wind distribution portion that is located at a position higher than a front portion of the center tunnel, and distributes the generated air conditioning air to each portion of the passenger compartment; and a foot duct that guides the air conditioning air blown from the wind distribution portion downward. The foot duct extends from above the center tunnel, passes outside in the vehicle width direction of the center tunnel, and extends downward.

[0011] According to this configuration, by providing the center pillar that is separated upward from the floor panel in the occupant space, the reinforcement effect of the vehicle body can be obtained, and as a result, the rigidity of the vehicle body can be improved. Further, the air distribution portion of the air conditioning device is positioned at a position higher than the center pillar, and thus the air distribution portion does not need to be disposed in the space below the center pillar. Further, the foot duct connected to the air distribution portion extends toward the lower side while passing outside in the vehicle width direction of the center pillar, and thus the foot duct does not need to be disposed in the space below the center pillar. Therefore, various components and devices and the like can be disposed in the space below the center pillar, and the degree of freedom of layout is improved.

[0012] In a second aspect of the present disclosure, the front portion of the center pillar is composed of a left side pillar member and a right side pillar member that are disposed apart from each other in the vehicle width direction. The foot duct includes a left side foot duct that extends toward the lower side while passing outside in the vehicle width direction of the left side pillar member from above the left side pillar member, and a right side foot duct that extends toward the lower side while passing outside in the vehicle width direction of the right side pillar member from above the right side pillar member.

[0013] According to this configuration, the air conditioning air can be blown to the left side and the right side of the occupant space by the left side foot duct and the right side foot duct, respectively, and thus the comfort of the occupant can be improved. In this case, the left side foot duct and the right side foot duct do not need to be disposed in the space below the center pillar, and thus the degree of freedom of layout of the space below the center pillar is not deteriorated.

[0014] The center pillar in a third aspect of the present disclosure is hollow. Between the left side pillar member and the right side pillar member, a duct is provided that communicates the air distribution portion of the air conditioning device with the inside of the center pillar and guides the air conditioning air blown from the air distribution portion into the inside of the center pillar. In a portion of the center pillar that is separated toward the rear of the vehicle from a connection portion that is connected to the duct, a blow portion is provided for blowing the air conditioning air in the center pillar.

[0015] According to this configuration, the air conditioning air generated by the air conditioning device is guided into the inside of the center pillar via the duct, and then blown from the blow portion. Since the center pillar extends in the front-rear direction, the air conditioning air can be guided to a desired portion in the front-rear direction in the occupant space. In this case, since the duct is provided between the left side pillar member and the right side pillar member, the duct does not need to be disposed in the space below the center pillar, and thus the degree of freedom of layout of the space below the center pillar is not deteriorated.

[0016] In a fourth aspect of the present disclosure, a control device that controls a controlled portion mounted on the vehicle is provided below the center pillar.

[0017] According to this configuration, the space below the center frame can be effectively utilized as a layout space for the control device. Further, the control device is weak to heat, and in the present configuration, since the center frame is positioned above the control device, direct sunlight from the outside is blocked by the center frame, and temperature rise of the control device is suppressed.

[0018] In the fifth aspect of the present disclosure, a cross section of the foot pipe orthogonal to the air flow direction is configured to have a dimension in the vehicle front-rear direction that is longer than a dimension in the vehicle width direction.

[0019] According to this configuration, the cross section of the foot pipe is a flat shape that is long in the vehicle front-rear direction, so the extension of the foot pipe in the vehicle width direction can be suppressed, and the cross-sectional area can be expanded to ensure a large amount of air supply.

[0020] Effects of the Invention

[0021] As described above, since the center frame is provided by being separated upward from the floor panel, the air distribution portion of the air conditioning device is provided at a position above the center frame, and the pipe that guides the air conditioning air downward is provided so as to extend from above the center frame toward the outside in the vehicle width direction of the center frame and downward, so the layout freedom in the passenger compartment can be improved while improving the rigidity of the vehicle body by the center frame.

[0050] Embodiments of the present application are described in detail below based on the drawings. Note that the following description of preferred embodiments is in no way limiting, but merely exemplary of the present application and its applications or uses.

[0051] Figure 1is a side view of the automobile 1 having the vehicle body structure A according to the embodiment of the present application, as viewed from the left side. In the description of the embodiment, the vehicle front-rear direction will be simply referred to as the "front-rear direction", the vehicle front side will be simply referred to as the "front side", and the vehicle "rear side" will be simply referred to as the rear. Further, the vehicle width direction is the vehicle left-right direction, the vehicle left side will be simply referred to as the "left side", and the vehicle right side will be simply referred to as the "right side".

[0052] (Overall configuration of automobile)

[0053] The automobile 1 is a passenger car, and an occupant space R1 for an occupant to ride is provided at a middle portion in the front-rear direction of the automobile 1. In the occupant space R1, a front seat (front-seat seat) FS constituting a front seat and a rear seat (rear-seat seat) RS constituting a rear seat are provided. The front seat FS includes a driver's seat disposed on the right side (or the left side) of the occupant space R1 and a front passenger's seat disposed on the left side (or the right side) of the occupant space R1. The rear seat RS is also disposed on the right side and the left side of the occupant space R1, respectively. Although not shown, a third seat can also be disposed behind the rear seat RS. Further, the rear seat RS is not essential and can be omitted.

[0054] A front door FD and a rear door RD are provided on the left side and the right side of the occupant space R1, respectively. In the case of the automobile 1 without the rear seat RS, the rear door RD can be omitted.

[0055] A front side space R2 is provided in front of the occupant space R1 of the automobile 1. In this front side space R2, a powertrain PT can be mounted as needed. In the case where the powertrain PT is mounted in the front side space R2, the front side space R2 can also be referred to as, for example, a powertrain housing chamber, a motor compartment, an engine compartment, or the like. A bonnet hood BF is provided at an upper portion of the front side space R2.

[0056] A trunk space R3 capable of accommodating luggage and the like is provided behind the occupant space R1 of the automobile 1. The trunk space R3 is openable and closable by a trunk lid TR. A rear side space R4 is provided behind the occupant space R1 of the automobile 1 and below the trunk space R3. In this rear side space R4, a powertrain PT that generates power for the automobile 1 can be mounted as needed. In the case where the powertrain PT is mounted in the rear side space R4, the rear side space R4 can also be referred to as, for example, a powertrain housing chamber, a motor compartment, an engine compartment, or the like.

[0057] The power unit PT can be mounted in both the front space R2 and the rear space R4, or can be mounted in only one of them. In the case where the power unit PT is mounted in only the front space R2, it is a front-wheel drive vehicle in which the power unit PT drives only the front wheels FT. In the case where the power unit PT is mounted in only the rear space R4, it is a rear-wheel drive vehicle in which the power unit PT drives only the rear wheels RT. In the case where the power unit PT is mounted in both the front space R2 and the rear space R4 to drive both the front wheels FT and the rear wheels RT, it is a four-wheel drive vehicle.

[0058] The power unit PT includes at least a traveling motor M (shown in Figure 2 ) for driving the drive wheels, and as needed, a speed reducer, a transmission, etc. Thus, the automobile 1 is an electric automobile. The traveling motor M is disposed so that its rotation center extends in the left-right direction. The power unit PT can include, in addition to the traveling motor M, for example, a control unit, etc. An internal combustion engine can also be included in the power unit PT. A battery unit Y (also shown in Figure 1 ) for supplying electric power to the traveling motor M is mounted in the lower portion of the automobile 1. For example, charging of the battery unit Y can be performed using power generated by the internal combustion engine, or at least one of the front wheels FT and the rear wheels RT can be driven by power generated by the internal combustion engine.

[0059] The type of the automobile 1 can also be Figure 1 a four-door vehicle as shown in the example, and for example, can be an automobile without a rear door RD. Further, although not shown, the present application can also be applied to an automobile in which the rear space R4 is opened and closed by a tailgate, like a hatchback car.

[0060] As shown in Figure 2 , the automobile 1 is provided with a lower structure 2 and an upper structure 3, and the vehicle body structure A is constituted by the lower structure 2 and the upper structure 3. In Figure 2 , the state after the doors FD, RD, the hood BF, the fenders, the window glass, the roof, the center pillar, the rear pillar, the bumper, the front and rear garnish devices, the instrument panel, the front and rear seats, etc. that are originally provided in the upper structure 3 are detached is shown. Further, in Figure 2 , the state after the front wheels FT, the rear wheels RT, the suspension device, etc. that are originally provided in the lower structure 2 are detached is shown.

[0061] The lower structure 2 is provided with a battery unit Y. The battery unit Y has a front-side battery FB and a rear-side battery RB, and a frame-shaped frame 10 that surrounds the front-side battery FB and the rear-side battery RB. Further, the lower structure 2 is provided with a front support frame 20 that extends toward the front from the front portion of the frame-shaped frame 10, and a rear support frame 30 that extends toward the rear from the rear portion of the frame-shaped frame 10.

[0062] Although not shown, in the case of a general electric vehicle, the battery unit is often provided under the floor as a member separate from the vehicle body in a manner that allows the battery unit to be attached and detached, but in the present embodiment, not only the batteries FB, RB but also the front support frame 20 and the rear support frame 30 are integrated on the frame-shaped frame 10 that surrounds the batteries FB, RB, and the front support frame 20 and the rear support frame 30 are also capable of being attached and detached with respect to the upper structure 3 together with the batteries FB, RB.

[0063] Specifically, the vehicle 1 of the present embodiment is configured to be vertically split into the lower structure 2 having the batteries FB, RB and the upper structure 3 that forms the passenger compartment Rl and the trunk space R3. The vertical split means that the lower structure 2 is integrated with respect to the upper structure 3 using fastening members such as bolts and nuts, screws, and the like, rather than using welding and adhesion and the like. Thus, when the vehicle 1 is handed over to the user after maintenance and repair, the lower structure 2 can be separated from the upper structure 3 as needed, and thus the maintainability is good.

[0064] Here, as a vehicle body structure of a vehicle, a ladder frame type vehicle body structure is known. In the case of the ladder frame type vehicle body structure, it is vertically split into a ladder frame and a cabin, but since the ladder frame extends continuously in the front-rear direction, it mainly receives a collision load at the time of a front collision and at the time of a rear collision. At the time of a side collision, the ladder frame only receives the collision load assistively, and the cabin mainly receives the collision load. In this way, in the ladder frame type vehicle body structure, the members that receive the collision load at the time of a front collision and at the time of a rear collision are distinguished from the members that receive the collision load at the time of a side collision.

[0065] In the case of the vehicle 1 of the present embodiment, although the lower structure 2 having the front support frame 20 and the rear support frame 30 is vertically split from the upper structure 3, the collision load is received by both the lower structure 2 and the upper structure 3 at the time of a front collision and at the time of a rear collision as well as at the time of a side collision, and thus the collision load can be dispersed to both the structures 2, 3 to be absorbed, which is quite different from the technical idea of the conventional ladder frame type vehicle body structure. The configurations of the lower structure 2 and the upper structure 3 will be described in turn.

[0066] (Lower Structure)

[0067] First, the lower structure 2 will be described. The lower structure 2 has, in addition to the batteries FB, RB, the frame-shaped frame 10, the front support frame 20, and the rear support frame 30, a powertrain PT, front wheels FT, rear wheels RT, and the like.

[0068] As shown in FIG. 1, the lower structure 2 has the batteries FB, RB, the frame-shaped frame 10, the front support frame 20, and the rear support frame 30. Figure 2As shown, the frame 10 is a component used to surround and protect the front battery FB and the rear battery RB. This frame 10 is a large component located below the passenger compartment side floor panel 41 (described later), extending from near the left end to near the right end of the passenger compartment side floor panel 41, and from near the front end to near the rear end of the passenger compartment side floor panel 41. The batteries FB and RB can be, for example, lithium-ion batteries, all-solid-state batteries, or other rechargeable batteries. Furthermore, the batteries FB and RB can be either individual battery cells or battery packs containing multiple battery cells.

[0069] The frame 10 includes a left side member 11, a right side member 12, a front member 13, and a rear member 14. The left side member 11, right side member 12, front member 13, and rear member 14 are, for example, made of extruded aluminum alloy, but can also be made of pressed aluminum alloy sheet or steel sheet. In the following description, "extruded" refers to an extruded aluminum alloy, and "pressed" refers to a pressed aluminum alloy sheet or steel sheet. Furthermore, each component can also be made of, for example, castings or die-castings.

[0070] When the lower structure 2 is attached to the upper structure 3, the front member 13 is fastened to the lower part of the front bulkhead 50 by fastening members, and the left side member 11 and the right side member 12 are fastened to the left and right side beams 60 by fastening members respectively. Furthermore, the rear member 14 is fastened to the connecting panel 43 (described later) by fastening members. A cover member 15 is installed at the lower part of the frame 10. Additionally, the power from the batteries FB and RB housed within the frame 10 is supplied to the driving motor M via a driving control circuit (not shown). Furthermore, the batteries FB and RB can be charged via a charging socket (not shown).

[0071] like Figure 2 As shown, the front support frame 20 has a pair of left and right sides connected to the front side members 13 of the frame frame 10. The front powertrain PT is mounted to the front support frame 20 via mounting members not shown.

[0072] The rear support frame 30, like the front support frame 20, has a pair of left and right side members 14 connected to the rear side members 14 of the frame frame 10. The rear powertrain PT is mounted to the rear support frame 30 via mounting members not shown.

[0073] (Upper structure)

[0074] Next, the upper structure 3 will be described. The upper structure 3 includes a floor member 40, a dash panel 50, and a pair of side sills 60. The floor member 40 is a member disposed above the frame 10 and the rear support 30 of the lower structure 2. The floor member 40 includes a passenger space side floor panel 41 that constitutes a floor of a passenger space Rl in which a front seat FS and a rear seat RS (indicated in FIG. 1) are disposed, a trunk space side floor panel 42 that constitutes a floor of a trunk space R3, and a connecting panel 43 that connects a rear portion of the passenger space side floor panel 41 and a front portion of the trunk space side floor panel 42. Figure 1

[0075] The floor member 40 can be formed by press-molding a steel sheet or the like, for example. The passenger space side floor panel 41, the trunk space side floor panel 42, and the connecting panel 43 can be integrally formed or can be formed separately and then connected. In this embodiment, although the floor member 40 is described as being divided into the passenger space side floor panel 41, the trunk space side floor panel 42, and the connecting panel 43, the floor member 40 including these panels 41 to 43 can be referred to as a floor panel. In addition, the passenger space side floor panel 41 can be referred to as a floor panel alone.

[0076] The passenger space side floor panel 41 extends from a front portion to a rear portion of the passenger space Rl and extends from a left side portion to a right side portion of the passenger space Rl. The passenger space side floor panel 41 of this embodiment is a floor tunnel-less structure that does not have a tunnel portion. That is, in a floor panel of a conventional automobile, a tunnel portion that greatly bulges upward and extends in the front-rear direction is generally provided. The tunnel portion is a portion through which, for example, an exhaust pipe that extends rearward from an engine mounted in an engine compartment at a front portion of the vehicle or a propeller shaft that transmits output of the engine to rear wheels passes. In many cases, the exhaust pipe and the propeller shaft have a diameter of, for example, 10 cm or more, and in order to prevent interference between the exhaust pipe or the propeller shaft and the floor panel in advance, a gap of at least several cm or more is required between the exhaust pipe or the propeller shaft and the floor panel. Further, in some cases, an insulator or the like is provided to an inner surface of the tunnel portion. For these reasons, the tunnel portion has a height of, for example, 15 cm or more or 20 cm or more from the floor panel, and in terms of the positional relationship with the seat, the upper end of the tunnel portion is higher than the lower end of a seat cushion on a seat rail or a central portion in the up-down direction of the seat cushion. A structure in which the tunnel portion does not greatly bulge upward is a tunnel-less structure.

[0077] ​The passenger space side floor panel 41 can also have, for example, a low bulging portion from the upper surface of the passenger space side floor panel 41 having a height of 5 cm or less or 10 cm or less, even though it does not have a passage portion having a height of 15 cm or more or 20 cm or more from the upper surface of the passenger space side floor panel 41, as described above. In the case of such a low bulging portion, since the exhaust pipe and the drive shaft cannot pass through the inside thereof, it does not function as a passage portion. Therefore, even if the passenger space side floor panel 41 has a low bulging portion having a height of 5 cm or less or 10 cm or less from the upper surface of the passenger space side floor panel 41, it is a floor panel of the no passage construction.

[0078] In the present embodiment, since the powertrain PT includes the travel motor M, it is not necessary to mount an internal combustion engine in the front side space R2, and thus it is possible to not guide the exhaust pipe to the rear of the vehicle. Further, if the powertrain PT is mounted in the rear side space R4, it is also possible to drive the rear wheels RT by the powertrain PT, and it is possible to omit the drive shaft. Therefore, it is possible to provide the passenger space side floor panel 41 as a floor panel of the no passage construction.

[0079] As also shown in Figure 3 In the middle portion in the front-rear direction of the passenger space side floor panel 41, a recessed portion 41a is formed so as to bulge downward. The recessed portion 41a has a floor surface portion 41b on which the feet of a rear seat occupant seated on the rear seat RS can be placed. The floor surface portion 41b is formed substantially horizontally. The front side portion of the recessed portion 41a is formed so as to gradually deepen toward the rear side. The recessed portion 41a can be continuously formed from the left side portion to the right side portion of the passenger space side floor panel 41. The floor surface portion 41b is provided at substantially the same height as the lower portion of the side beam 60 described later, and thus the height of the floor surface portion 41b can be sufficiently reduced. The positional relationship between the recessed portion 41a and the seat cushion of the rear seat RS in the front-rear direction is set such that, when the rear seat occupant seated on the rear seat RS places the feet directly below, the feet are naturally placed on the floor surface portion 41b. The position of the front portion of the recessed portion 41a is set such that, when the rear seat occupant seated on the rear seat RS moves the feet obliquely forward, the feet are placed on the floor surface portion 41b. That is, the position of the recessed portion 41a and the dimension in the front-rear direction are set such that, even if the rear seat occupant moves the feet a little forward and rearward, the feet can be placed on the floor surface portion 41b. Thus, the foot space of the rear seat occupant can be enlarged, and the ride comfort is improved. In the central portion in the left-right direction of the recessed portion 41a, a floor cross member 41c extending in the front-rear direction is provided. By providing the floor cross member 41c, the portion in which the recessed portion 41a is formed can be reinforced.

[0080] The trunk space side floor panel 42 is positioned above the passenger space side floor panel 41. The rear side space R4 is located below the trunk space side floor panel 42. Because the trunk space side floor panel 42 is positioned above the passenger space side floor panel 41, the connecting panel 43 extends vertically.

[0081] like Figure 4 As shown in the diagram, the front bulkhead 50 is a component that serves as a partition between the front side space R2 and the passenger space R1. It extends upward from the front of the passenger space side floor panel 41 and also extends in the left and right directions, dividing the front of the passenger space R1. Figure 4 It is a cross-sectional view showing the case where the vehicle body is cut by a surface that passes through the center of the vehicle body in the width direction and extends in the front-rear direction.

[0082] like Figure 2 and Figure 3 As shown, the left and right side beams 60 are arranged to extend in the front-rear direction from the left and right ends of the passenger compartment side floor panel 41, respectively. The left side beam 60 is connected to the left end of the passenger compartment side floor panel 41 at its midpoint in the vertical direction. Since the battery unit Y, which includes batteries FB and RB, is arranged below the passenger compartment side floor panel 41, the lower part of the side beam 60 is configured to coincide with the batteries FB and RB when the vehicle is viewed from the side. Similarly, the right side beam 60 is also connected to the right end of the passenger compartment side floor panel 41.

[0083] The upper structure 3 has a pair of left and right hinge pillars 70. Left and right front doors FD are rotatably mounted on the left and right hinge pillars 70 respectively. Figure 1 (As shown). The left edge of the front bulkhead 50 is connected to the right side of the left hinge pillar 70. Furthermore, the right edge of the front bulkhead 50 is connected to the left side of the right hinge pillar 70. Additionally, although not shown, a center pillar and a rear pillar are also provided on the upper structure 3.

[0084] like Figure 2 and Figure 3 As shown, the passenger compartment side floor panel 41 has a front crossbeam 44A, a middle crossbeam 44B, a front side crossbeam 44C of the recess, and a rear side crossbeam 44D of the recess. The front crossbeam 44A, the middle crossbeam 44B, the front side crossbeam 44C of the recess, and the rear side crossbeam 44D of the recess extend in the left-right direction and are fixed to the upper surface of the passenger compartment side floor panel 41.

[0085] like Figure 4As shown, the front crossbeam 44A is disposed at the front of the passenger compartment side floor panel 41. The front of the front crossbeam 44A also connects to the lower part of the front bulkhead 50. The middle crossbeam 44B is disposed behind the front crossbeam 44A and in front of the recess 41a, and the middle crossbeam 44B and the passenger compartment side floor panel 41 form a closed section.

[0086] like Figure 3 As shown, the front crossbeam 44C of the recessed portion extends in the left-right direction behind the middle crossbeam 44B along the front part of the recessed portion 41a. The rear crossbeam 44D of the recessed portion extends in the left-right direction behind the front crossbeam 44C along the rear part of the recessed portion 41a. The front part of the floor frame 41c, which is located inside the recessed portion 41a, is connected to the center part of the front crossbeam 44C in the left-right direction, and the rear part of the floor frame 41c is connected to the center part of the rear crossbeam 44D in the left-right direction.

[0087] like Figure 2 and Figure 3 As shown, the upper structure 3 has a central frame 80 that extends continuously in the front-rear direction from the front bulkhead 50 to the connecting panel 43. The central frame 80 is located in the center in the left-right direction and is disposed separately from the floor panel 41 on the passenger compartment side upwards. On the left side of the central frame 80, the left front seat FS and the rear seat RS are disposed, and on the right side of the central frame 80, the right front seat FS and the rear seat RS are disposed.

[0088] By separating the center frame 80 from the passenger compartment side floor panel 41 and positioning it upwards, components, for example, can be arranged between the lower surface of the center frame 80 and the upper surface of the passenger compartment side floor panel 41. Furthermore, the area between the lower surface of the center frame 80 and the upper surface of the passenger compartment side floor panel 41 can be used as an item storage area. Figure 4 As shown, the center frame 80 of this embodiment has a bent portion 80A in the vertical direction at its midpoint in the front-rear direction. By providing the bent portion 80A on the center frame 80, for example, the rear portion can be made lower than the front portion, thus improving the comfort of the rear passenger. Furthermore, since the front portion of the center frame 80 can be made higher than the rear portion, items such as objects can be placed below the front portion of the center frame 80. The bent portion 80A is formed at a position of the center frame 80 that is forward of the midpoint in the front-rear direction.

[0089] That is, such as Figure 3As shown, the center stand 80 has a front side member 81 extending in the front-rear direction, a rear side member 82 provided at the vehicle rear of the front side member 81 and extending rearward, and a connecting member 83 connecting the rear portion of the front side member 81 with the front portion of the rear side member 82. The front side member 81 and the rear side member 82 are hollow, i.e., cylindrical, and can be formed of extruded members, for example. By making the front side member 81 and the rear side member 82 hollow, a lightweight and highly rigid member can be obtained. In the case where the center stand 80 is used as a blowout mechanism of air-conditioning air to be described later, the rear portion of the rear side member 82 can also be closed. The rear portion of the rear side member 82 is joined to the connection panel 43.

[0090] The vertical cross section of the front side member 81 and the rear side member 82 along the vehicle width direction is rectangular, and therefore, as shown, the front side member 81 and the rear side member 82 have upper and lower wall portions extending in the left-right direction and left and right side wall portions extending in the up-down direction. Note that the cross-sectional shape of the front side member 81 and the rear side member 82 is not limited to a rectangular shape, and can be a polygonal shape of five sides or more, or a circular or elliptical shape. Figure 5

[0091] The lengthwise dimension of the rear side member 82 is set to be longer than the lengthwise dimension of the front side member 81. Therefore, the connecting portion of the front side member 81 and the rear side member 82 is located at a position forward of the central portion in the front-rear direction of the occupant space R1. Note that the center stand 80 is not limited to the two-part construction of the front side member 81 and the rear side member 82, and can be formed of one member from the front portion to the rear portion, or can be a three-part construction.

[0092] As shown in FIG. 2, the front side member 81 is inclined at a first inclination angle with respect to the horizontal plane and extends linearly. On the other hand, the rear side member 82 is inclined at a second inclination angle smaller than the first inclination angle with respect to the horizontal plane and extends linearly. That is, the rear side member 82 is inclined at a different inclination angle from the front side member 81, and thus a bent portion 80A bent toward the lower side is formed at the connecting portion of the front side member 81 and the rear side member 82. In this embodiment, the rear side member 82 is configured to be inclined downward toward the rear side. Note that the front side member 81 and the rear side member 82 can also be inclined at the same inclination angle. In this case, the bent portion 80A is not formed. Figure 4 As shown in FIG. 2, the front side member 81 is inclined at a first inclination angle with respect to the horizontal plane and extends linearly. On the other hand, the rear side member 82 is inclined at a second inclination angle smaller than the first inclination angle with respect to the horizontal plane and extends linearly. That is, the rear side member 82 is inclined at a different inclination angle from the front side member 81, and thus a bent portion 80A bent toward the lower side is formed at the connecting portion of the front side member 81 and the rear side member 82. In this embodiment, the rear side member 82 is configured to be inclined downward toward the rear side. Note that the front side member 81 and the rear side member 82 can also be inclined at the same inclination angle. In this case, the bent portion 80A is not formed.

[0093] Figure 6 As shown in FIG. 2, the front side member 81 is inclined at a first inclination angle with respect to the horizontal plane and extends linearly. On the other hand, the rear side member 82 is inclined at a second inclination angle smaller than the first inclination angle with respect to the horizontal plane and extends linearly. That is, the rear side member 82 is inclined at a different inclination angle from the front side member 81, and thus a bent portion 80A bent toward the lower side is formed at the connecting portion of the front side member 81 and the rear side member 82. In this embodiment, the rear side member 82 is configured to be inclined downward toward the rear side. Note that the front side member 81 and the rear side member 82 can also be inclined at the same inclination angle. In this case, the bent portion 80A is not formed. Figure 7 ​​As shown, inside the rear frame member 82, a first partition wall 82a is provided, extending in both the width and front-rear directions, to divide the internal space into an upper passage and a lower passage. Further, inside the rear frame member 82, a second partition wall 82b is provided, extending in both the vertical and front-rear directions, to divide the space into a left passage (left side in the width direction) and a right passage (right side in the width direction). The first partition wall 82a and the second partition wall 82b are integrally formed. Through the first partition wall 82a and the second partition wall 82b, four passages are formed inside the rear frame member 82: an upper left passage T11, an upper right passage T12, a lower left passage T13, and a lower right passage T14. The first partition wall 82a and the second partition wall 82b function as ribs provided inside the center frame 80. Furthermore, the first partition wall 82a and the second partition wall 82b can be provided as needed, and one or both can be omitted. In addition, more than three partition walls can be provided.

[0094] Furthermore, similarly to the rear structure member 82, a first partition wall 81a is provided inside the front structure member 81, extending in both the vehicle width and longitudinal directions. This first partition wall 81a divides the interior space of the front structure member 81 into an upper passage and a lower passage. Additionally, a second partition wall 81b is also provided inside the front structure member 81, dividing the space into a left passage (left side in the vehicle width direction) and a right passage (right side in the vehicle width direction). Through the first partition wall 81a and the second partition wall 81b, the front structure member 81, like the rear structure member 82, forms an upper left passage T11, an upper right passage T12, a lower left passage T13, and a lower right passage T14.

[0095] like Figures 8-10 As shown, the connecting member 83 is a cylindrical shape that allows communication between the rear part of the front frame member 81 and the front part of the rear frame member 82. The rear part of the front frame member 81 and the front part of the rear frame member 82 are connected in a state where they are inserted into the connecting member 83. Specifically, the connecting member 83 has an upper wall portion 83a and a lower wall portion 83b extending in the left-right direction, and a left wall portion 83c and a right wall portion 83d extending in the up-down direction. The upper wall portion 83a extends from the upper part of the left wall portion 83c to the upper part of the right wall portion 83d, and the lower wall portion 83b extends from the lower part of the left wall portion 83c to the lower part of the right wall portion 83d. The front-back dimension of the lower wall portion 83b of the connecting member 83 is set to be longer than the front-back dimension of the upper wall portion 83a. Corresponding to the difference in the front-back dimensions of the upper wall portion 83a and the lower wall portion 83b, the front-back dimensions of the left wall portion 83c and the right wall portion 83d are longer towards the lower side.

[0096] In the interior of the connecting member 83, a first connecting wall portion 83e extending in the left-right direction from the upper-lower direction middle portion of the left wall portion 83c to the upper-lower direction middle portion of the right wall portion 83d, and a second connecting wall portion 83f extending from the left-right direction middle portion of the upper wall portion 83a to the left-right direction middle portion of the lower wall portion 83b are provided. The first connecting wall portion 83e and the second connecting wall portion 83f are integrally formed with the upper wall portion 83a, the lower wall portion 83b, the left wall portion 83c, and the right wall portion 83d.

[0097] On the front side of the second connecting wall portion 83f, a front-side notch portion 83g into which the rear portion of the front side frame member 81 is inserted is formed. Further, on the rear side of the second connecting wall portion 83f, a rear-side notch portion 83h into which the front portion of the rear side frame member 82 is inserted is formed. If the front side frame member 81 and the rear side frame member 82 are connected by the connecting member 83, the upper left passage T11, the upper right passage T12, the lower left passage T13, and the lower right passage T14 of the front side frame member 81 communicate with the upper left passage T11, the upper right passage T12, the lower left passage T13, and the lower right passage T14 of the rear side frame member 82, respectively.

[0098] Further, as shown in Figure 5 the center frame 80 has a left side frame constituting member 84A and a right side frame constituting member 84B that constitute the front portion of the center frame 80, and thus has a shape branched in the left-right direction. The left side frame constituting member 84A and the right side frame constituting member 84B are disposed apart from each other in the left-right direction. The rear portion of the left side frame constituting member 84A is fixed to the left side surface of the front-rear direction middle portion of the front side frame member 81. The left side frame constituting member 84A is inclined in plan view in such a manner that the farther to the front side, the more to the left side. The front portion of the left side frame constituting member 84A is connected to the portion of the front wall 50 that is separated upward from the passenger space side floor panel 41.

[0099] Further, the rear portion of the right side frame constituting member 84B is fixed to the right side surface of the front-rear direction middle portion of the front side frame member 81. The right side frame constituting member 84B is inclined in plan view in such a manner that the farther to the front side, the more to the right side. The front portion of the right side frame constituting member 84B is connected to the portion of the front wall 50 that is separated upward from the passenger space side floor panel 41.

[0100] Further, as shown in Figure 3As shown, the upper structure 3 includes first to third connecting structural members 101 to 103. These first to third connecting structural members 101 to 103 extend upwards from the passenger compartment side floor panel 41, and are fixed to the center frame 80 at their upper parts, serving as components for connecting the center frame 80 to the passenger compartment side floor panel 41. The first connecting structural member 101 is positioned at the foremost point in the passenger compartment R1, and is separated rearwards from the front bulkhead 50. The lower part of the first connecting structural member 101 is fixed to the rearward-separating portion of the passenger compartment side floor panel 41, and the upper part is fixed to the rearward-separating portion of the center frame 80. Furthermore, a second connecting structural member 102 is separated rearwards from the first connecting structural member 101. The lower part of the second connecting structural member 102 is connected to the intermediate crossbeam 44B. Furthermore, the third structural member 103 is separated from the second structural member 102 and arranged rearward. The lower part of the third structural member 103 is connected to the front crossbeam 44C of the recess.

[0101] like Figure 5 As shown, the first connecting structural member 101 has a left-side member (left-side connecting structural member) 101A and a right-side member (right-side connecting structural member) 101B. The lower parts of the left-side member 101A and the right-side member 101B are fixed to the front crossbeam 44A. In the front view, the left-side member 101A extends obliquely upward from the front crossbeam 44A, becoming more leftward as it goes upward. The upper part of the left-side member 101A is fixed to the front part of the left-side structural member 84A of the center frame 80. Similarly, in the front view, the right-side member 101B extends obliquely upward from the front crossbeam 44A, becoming more rightward as it goes upward. The upper part of the right-side member 101B is fixed to the front part of the right-side structural member 84B of the center frame 80. Since the front part of the left structural component 84A and the front part of the right structural component 84B are separated in the left-right direction, the left component 101A and the right component 101B, except for the lower part, are separated in the left-right direction. The left-right spacing between the left component 101A and the right component 101B is wider as it moves upward.

[0102] like Figure 4 As shown, the upper structure 3 has an air conditioning unit 120 that generates air conditioning air to blow into the passenger space R1. The air conditioning unit 120 is positioned forward of the front of the front side structure member 81, in front of the center frame 80.

[0103] The air conditioning device 120 has a cooler (heat exchanger) 121 through which air conditioning air passes, an air conditioning case 122 that houses the cooler 121, and a wind distribution portion 123. The cooler 121 is a cooling heat exchanger composed of an evaporator or the like for cooling air conditioning air, but is not limited thereto and can also be a heating heat exchanger composed of a heating core that heats air conditioning air, a condenser, or the like. The cooler 121 of this embodiment is disposed at a position further forward than the dash panel 50.

[0104] Inside the air conditioning case 122 of the air conditioning device 120, in addition to the aforementioned cooler 121, a heater that is not shown and an air mixing damper 122a for changing the mixing ratio of cool air that has passed through the cooler 121 and warm air that has passed through the heater to generate air conditioning air of a desired temperature are housed. The portion of the air conditioning case 122 that houses the cooler 121 and the air mixing damper 122a is disposed at a position further forward than the dash panel 50.

[0105] As shown in FIG. 1, the air conditioning case 122 is disposed at a position further forward than the center console 80 and further upward than the front seats 10 and 20. The air conditioning case 122 is disposed at a position further forward than the dash panel 50 and further upward than the front seats 10 and 20. Figure 11 As shown in FIG. 1, the air conditioning case 122 is disposed at a position further forward than the center console 80 and further upward than the front seats 10 and 20. The air conditioning case 122 is disposed at a position further forward than the dash panel 50 and further upward than the front seats 10 and 20.

[0106] As shown in FIG. 1, the air conditioning case 122 is disposed at a position further forward than the center console 80 and further upward than the front seats 10 and 20. The air conditioning case 122 is disposed at a position further forward than the dash panel 50 and further upward than the front seats 10 and 20. Figure 4 Inside the wind distribution portion 123, a plurality of blow direction switching dampers 123b are provided. By the operation of the blow direction switching dampers 123b, air conditioning air can be supplied toward the inner surface of the front window glass FG (shown in FIG. 1), or toward the upper body of the occupant, or toward the vicinity of the feet of the occupant. The operation of the blow direction switching dampers 123b is known from the prior art. Inside the wind distribution portion 123, a blow direction switching damper 123b for the rear seat is also provided. Figure 1

[0107] ​The air distribution unit 123 has an outlet section 123c that is shaped like a pipe for blowing out air conditioning air generated inside the air conditioning housing 122. The air conditioning unit 120 also has a guide duct 120d that communicates the interior of the air distribution unit 123 with the interior of the center frame 80, and guides the air conditioning air blown out from the outlet section 123c of the air distribution unit 123 into the interior of the center frame 80. The guide duct 120d is disposed above the control device 130 described later, between the left side frame assembly member 84A and the right side frame assembly member 84B, and extends in the front-rear direction. The front part of the guide duct 120d is connected to the outlet section 123c, and the rear part of the guide duct 120d is connected to the front part of the front side frame member 81 of the center frame 80. Thus, the air conditioning air generated by the air conditioning unit 120 is guided into the interior of the center frame 80 via the guide duct 120d. The guide duct 120d may also be a component constituting part of the center frame 80.

[0108] Since the center frame 80 extends in the front-to-back direction, the air conditioning air can be guided to the desired location in the front-to-back direction of the passenger space R1. In this case, since the air duct 120d is positioned above the control device 130 and has a predetermined width in the left-to-right direction, direct sunlight is also blocked by the air duct 120d, making it even more difficult for it to reach the control device 130. Furthermore, by utilizing the center frame 80 as an air conditioning duct, there is no need to install a separate air conditioning duct, and the passenger space R1 can be expanded compared to the case where a separate air conditioning duct is installed.

[0109] like Figure 3 As shown, on the upper wall of the center frame 80, a portion separating rearward from the air duct 120d is provided with an upper air supply section 80b for directing air conditioning air from the upper left passage T11 and the upper right passage T12 upward. The upper air supply sections 80b are located on the upper wall of the center frame 80, positioned rearward than the backrest of the front seat FS, and are located on the left and right sides respectively. The left upper air supply section (left side air supply section) 80b is cylindrical, communicating into the upper left passage T11, and the right upper air supply section (right side air supply section) 80b is cylindrical, communicating into the upper right passage T12. The downstream end of the upper air supply section 80b opens upward toward the occupant seated in the rear seat RS.

[0110] On the lower wall portion of the center frame 80, a portion separated rearward from the air duct 122d is provided with a lower side air supply portion 80c for supplying air-conditioned air in the left lower passage T13 and the right lower passage T14 downward. The lower side air supply portion 80c is located rearward of the seat cushion portion of the front seat FS and is provided on the left and right sides of the lower wall portion of the center frame 80. The left side lower side air supply portion 80c is in a tubular shape that communicates with the left lower passage T13, and the right side lower side air supply portion 80c is in a tubular shape that communicates with the right lower passage T14. The lower side air supply portion 80c is formed of a rear heater duct that extends downward toward the recessed portion 41a and is bent toward the outside in the vehicle width direction after extending downward from the center frame 80. One of the upper side air supply portion 80b and the lower side air supply portion 80c can be omitted.

[0111] Further, the center frame 80 has a large cross section that can increase the degree of torsional rigidity of the vehicle body, and thus the air supply sound is suppressed to be low even if the amount of air-conditioned air flowing inside is increased. In particular, since the center frame 80 extends in a shape close to a straight line, the passage inside is also close to a straight line, and thus the air supply sound can be suppressed to be low. Further, in the case where no thermal insulating material or the like is provided on the center frame 80, the air-conditioned air flowing inside the center frame 80 is transferred to the wall portion of the center frame 80, and is radiated from the outer surface of the wall portion toward the passenger compartment R1. Thus, a comfortable air conditioner using radiant heat can be achieved. Alternatively, a thermal insulating material can be provided on the center frame 80.

[0112] The air conditioning device 120 has foot ducts 124A, 124B that guide the air-conditioned air blown from the air distribution portion 123 downward. The foot ducts 124A, 124B include a left front foot duct 124A and a right front foot duct 124B that mainly supply warm air to the vicinity of the feet of an occupant seated on the front seat FS. The upstream end (upper end) of the left front foot duct 124A is disposed at a position higher than the left side frame constituent member 84A and is installed to the left side wall of the air distribution portion 123 to communicate with the inside of the air distribution portion 123. The left front foot duct 124A extends toward the left side above the left side frame constituent member 84A from the upstream end thereof and then extends downward along the left side surface of the left side frame constituent member 84A. The downstream end of the left front foot duct 124A opens downward. That is, the left front foot duct 124A extends from above the left side frame constituent member 84A to the outside in the vehicle width direction of the left side frame constituent member 84A and then extends downward.

[0113] Further, the upstream end (upper end) of the right front leg pipe 124B is arranged at a position higher than the right side frame member 84B, and is attached to the right side wall of the air distribution portion 123 to communicate with the inside of the air distribution portion 123. The right front leg pipe 124B extends toward the right side above the right side frame member 84B of the center frame 80 from the upstream end thereof, and then extends downward along the right side surface of the right side frame member 84B. The downstream end of the right front leg pipe 124B is opened toward the lower side. That is, the right front leg pipe 124B extends from above the right side frame member 84B to the outside in the vehicle width direction of the right side frame member 84B and downward.

[0114] Since the air distribution portion 123 is arranged above the left side frame member 84A and the right side frame member 84B, and the left front leg pipe 124A and the right front leg pipe 124B are arranged to extend sideward from above the left side frame member 84A and the right side frame member 84B, a space can be left below the center frame 80. By arranging an article or the like in the space below the center frame 80, the space can be effectively utilized. In this embodiment, as shown in Figs. 1 and 2, a control device 130 is arranged below the front side of the center frame 80. Figure 4 Figure 11

[0115] Further, the left front leg pipe 124A and the right front leg pipe 124B are arranged with a space therebetween in the left-right direction. Between the left front leg pipe 124A and the right front leg pipe 124B, an air guide pipe 120d extending in the front-rear direction is arranged, whereby the space between the left front leg pipe 124A and the right front leg pipe 124B can also be effectively utilized.

[0116] The cross section of the left front leg pipe 124A and the right front leg pipe 124B orthogonal to the air flow direction is set to be longer in the front-rear direction than in the vehicle width direction. Thus, the cross section of the leg pipes 124A, 124B is a flat shape longer in the front-rear direction, so that the leg pipes 124A, 124B can be suppressed from protruding in the vehicle width direction, and the cross-sectional area can be enlarged to ensure a large air supply amount. In addition, the leg pipes 124A, 124B can also extend to the vicinity of the floor panel 41 on the passenger compartment side. Further, one of the leg pipes 124A, 124B can also be omitted.

[0117] (LAYOUT OF CONTROL DEVICE)

[0118] The vehicle body structure A is provided with a control device 130 (shown in Figs. 1 and 2) that controls a controlled portion mounted on the automobile 1. Figure 4 Figure 11 ​​​). The controlled sections can include, for example, the powertrain PT, the brake device, the electronically controlled suspension device, the lighting device, the navigation device, the head-up display device, the audio device, the in-vehicle monitor, the television, and the like. The control device 130 that controls these controlled sections is large in size because it includes a high-performance CPU, a memory, and the like, and is weak against high temperatures and impacts. In the control device 130, a water jacket through which cooling water flows and the like are provided as a countermeasure against heat generation. In addition, there are cases where the control device 130 is mounted with an entertainment function (a video playback function, a music playback function), and the like, and in such cases, the control device 130 is also large in size.

[0119] The control device 130 of the present embodiment is disposed below the front portion of the center console 80 in the passenger space Rl. As shown by a broken line in FIG. 1, the control device 130 is disposed below the front portion of the center console 80 in the passenger space Rl. As shown by a broken line in FIG. 1, the control device 130 is disposed below the front portion of the center console 80 in the passenger space Rl. Figure 4 Above the front portion of the center console 80, an instrument panel IP that mounts instruments is disposed, as shown by a broken line. Figure 1

[0120] Since the control device 130 is disposed below the center console 80 in the passenger space Rl, direct sunlight from the outside is blocked by the center console 80 and is less likely to reach the control device 130. Therefore, the control device 130 can be disposed in a place that is advantageous in terms of heat. In addition, since the instrument panel IP is disposed above the control device 130, direct sunlight is also blocked by the instrument panel IP and is even less likely to reach the control device 130. In addition, since the control device 130 is covered by the instrument panel IP, it is less likely to be seen from the outside, and is also desirable in terms of safety.

[0121] In addition, an air duct 120d is disposed above the control device 130. Heat of the air-conditioned air is transferred to the wall portion of the air duct 120d and is radiated from the outer surface of the wall portion toward the control device 130 as radiant heat. At this time, since the air-conditioned air that is adjusted in temperature in such a manner as to make the passenger space Rl comfortable flows inside the air duct 120d, the radiant heat from the air duct 120d functions in such a manner as to suppress an increase in the temperature of the control device 130. In addition, direct sunlight can also be blocked by the air duct 120d.

[0122] (Cooling path)

[0123] Next, the cooling path will be described. Figure 13 ​is a view showing an outline configuration of a cooling path provided in the automobile 1. The cooler 121 is constituted by a cooling heat exchanger of the air conditioning device 120. A passage of cooling water as a heat exchange medium is formed in the cooler 121, and the cooling water circulating in the passage is cooled by heat exchange with low-temperature refrigerant in the interior of the cooler 121. The vehicle body structure A is provided with a supply pipe 131 for supplying the cooling water cooled by the cooler 121 to a water jacket (not shown) provided in the control device 130, and a discharge pipe 132 for discharging the cooling water supplied to the control device 130. A pump P for delivering the cooling water to the control device 130 is provided in the supply pipe 131. The cooling water discharged from the discharge pipe 132 is drawn into the pump P after being cooled by the cooler 121. By circulating the cooling water in this way, the control device 130 is cooled. Alternatively, refrigerant can be used instead of the cooling water.

[0124] As shown in Figure 4 , the cooler 121 is disposed at a position behind the powertrain PT on the front side, close to the cowl panel 50. Thus, the cooler 121 can be disposed closer to the control device 130 than the powertrain PT on the front side. As a result, the length of the supply pipe 131 can be shortened, and the pipe path can be simplified, and the pressure loss when the cooling water is supplied to the control device 130 can be reduced, and the loss of heat during the period from the cooler 121 to the control device 130 can be reduced, and the control device 130 can be efficiently cooled.

[0125] (EFFECTS OF THE EMBODIMENTS)

[0126] As described above, according to this embodiment, by providing the center pillar 80 separated upward from the floor panel 41 on the passenger compartment side at the passenger compartment Rl, a reinforcing effect of the vehicle body can be obtained, and as a result, the rigidity of the vehicle body can be improved. Further, the air distribution portion 123 of the air conditioning device 120 is disposed at a position higher than the center pillar 80, and therefore, the air distribution portion 123 does not need to be disposed in the space below the center pillar 80. Further, the foot tubes 124A and 124B connected to the air distribution portion 123 extend toward the lower side while passing outside in the vehicle width direction of the center pillar 80, and therefore, the foot tubes 124A and 124B do not need to be disposed in the space below the center pillar 80. Therefore, various components and devices and the like can be disposed in the space below the center pillar 80, and the degree of freedom of layout can be improved.

[0127] Further, since the left-side foot tube 124A and the right-side foot tube 124B are provided on the left and right sides of the air distribution portion 123, respectively, the air conditioning air can be blown to the left and right sides of the passenger compartment Rl through the left-side foot tube 124A and the right-side foot tube 124B, respectively, and the comfort of the passenger can be improved.

[0128] Further, the air-conditioned air generated by the air-conditioning device 120 is introduced to the interior of the center console 80 via the air duct 120d, and is blown out from the air supply portions 80b, 80c. Since the center console 80 extends in the front-rear direction, the air-conditioned air can be directed to a desired portion in the front-rear direction in the passenger compartment Rl. In this case, since the air duct 120d is disposed between the left side console component 84A and the right side console component 84B, it is not necessary to arrange the air duct 120d in the space below the center console 80, and the degree of freedom of layout of the space below the center console 80 is not deteriorated.

[0129] The foregoing embodiments are merely examples in all aspects and should not be construed as limiting. Further, modifications and changes within the scope of equivalents of the claims are included in the scope of the present application.

[0130] Industrial applicability

[0131] As explained above, the vehicle body structure of the present application can be used, for example, in electric vehicles and other vehicles.
