FIG. 2 is an exploded perspective view showing a part of the center structure 6 used for manufacturing the vehicle body of FIG.
The toe board panel 13 and the dash panel 27 are shown by FIG. 2 as a member which comprises the center structure 6. As shown in FIG. The dash panel 27 is joined to the upper edge of the toe board panel 13. The joined body of the toe board panel 13 and the dash panel 27 serves as a wall member that divides the front chamber 2 of the vehicle body 1 and the passenger compartment 3 shown in FIG. The toe board panel 13 is an example of the partition panel in the present invention.
The center structure 6 is disposed substantially at the center in the width direction of the vehicle body 1.

  Further, the toe board panel 13 is a molded body in which, for example, one metal plate is made to have an appropriate shape by press molding or the like. The toe board panel 13 has a pair of inner flanges 31 at both widthwise ends of the vehicle body 1, that is, at both left and right ends. The inner flanges 31 extend in the vertical direction at the left and right ends of the toe board panel 13. The inner flange portion 31 projects forward from both ends of the toe board panel 13 in the center structure 6.

FIG. 3 is a partial perspective view of the side structure 7 used for manufacturing the vehicle body 1. As a member which comprises the side structure 7, the A pillar 17, the side sill 15, the front upper member 18, and the stiffening member 19 for reinforcement are shown by FIG. The A-pillar 17 and the side sill 15 are examples of the side panel in the present invention.
At the front end of the side sill 15, an A-pillar 17 standing substantially vertically is joined. The front upper member 18 is joined to a substantially central portion in the height direction of the A-pillar 17. A reinforcement member 19 for reinforcement is joined between the front upper member 18 and the A-pillar 17.
The side structures 7 stand along the left and right end edges of the center structure 6 to form side portions of the vehicle body 1.

  Also, the A-pillar 17 has an outer flange portion 32. The outer flange portion 32 extends substantially in the vertical direction at the front edge of the A pillar 17 extending in the vertical direction. The outer flange portion 32 projects forward from the front edge of the A pillar 17 in the side structure 7.

Subsequently, with reference to FIG. 4, a manufacturing process of joining the center structure 6 and the side structure 7 in the vehicle body 1 shown in FIG. 1 will be described. FIG. 4 is a schematic cross-sectional view showing the toe board panel 13 and the A-pillar 17 in the case of being cut along the X-X plane of FIG.
The A-pillar 17 of FIG. 4 has an inner side panel 33 and an outer side panel 34. The A pillar 17 becomes a hollow square member by joining the inner side panel 33 and the outer side panel 34 at the rear not shown.

  The inner side panel 33 is a molded body obtained by molding a single metal plate, for example, and has a first outer flange portion 35. The first outer flange portion 35 is a front edge portion of the inner side panel 33 extending in the vertical direction. Since the first outer flange portion 35 is a part of the inner side panel 33, the first outer flange portion 35 extends in the vertical direction.

The outer side panel 34 is a molded body obtained by molding a single metal plate, for example, and has a second outer flange portion 36. The second outer flange portion 36 is a front edge portion of the outer side panel 34 extending in the vertical direction. Since the second outer flange portion 36 is a part of the outer side panel 34, it extends in the vertical direction.
In the A-pillar 17 shown in FIG. 4, the outer flange portion 32 of the A-pillar 17 is formed by the overlapped first and second outer flange portions 35 and 36.

  The inner side panel 33 and the outer side panel 34 may be a single steel plate as long as the rigidity of the side structure 7 is not reduced. Specifically, a single steel plate is bent at the rear not shown in FIG. 4, one end edge of the steel plate is a first outer flange portion, and the other end edge is a second outer flange portion. Similar to the outer flange portion 32 of the pillar 17, the outer flange portion may be formed by the overlapped first and second outer flange portions.

  When joining the center structure 6 and the side structure 7, as shown in FIG. 4A, first, the A pillars 17 of the side structure 7 are disposed in proximity to the toe board panel 13 of the center structure 6. At this time, the inner flange portion 31 and the outer flange portion 32 are superimposed.

Next, as shown in FIG. 4B, in a state where the inner flange portion 31 of the toe board panel 13 and the outer flange portion 32 of the A pillar 17 are overlapped, they are joined by spot welding or the like. As a result, a joint portion 37 in which the inner flange portion 31 of the toe board panel 13 and the outer flange portion of the A pillar 17 are joined is formed.
When the inner flange portion 31 and the outer flange portion 32 are joined by spot welding or the like, a plurality of joint points by spot welding are formed discretely at regular intervals.

Next, as shown in FIG. 4C, the structures 381 are arranged. The structural body 381 is disposed on the passenger compartment 3 side of the toe board panel 13. The structural body 381 is a member that suppresses large deformation or breakage of the toe board panel 13 by supporting the toe board panel 13 from the rear. The arrangement location of the structural body 381 is inside the joint portion 37 in the width direction of the vehicle body 1. In the vehicle body structure of the vehicle according to the present invention, the arrangement location of the structure is not particularly limited as long as the partition panel such as the toe board panel 13 can be supported from the rear.
In FIG. 4C, a structural body 381 attached to the left joint 37 of the vehicle body 1 is shown. However, a similar structure 381 can be attached to the right joint of the vehicle body 1. That is, in the present embodiment, the structural bodies 381 are a pair of members that can be provided on the left and right sides of the vehicle body 1.
As described above, the vehicle body 1 in which the center structure 6 and the side structure 7 are joined and the structural body 381 is attached and in which the collision safety performance is further improved as compared with the conventional case is manufactured.

In the present invention, any of the step of arranging the structure and the step of joining the inner flange portion and the outer flange portion may be performed first.
When the process of arranging the structure is first performed, specifically, the A-pillar 17 of the side structure 7 is arranged close to the toe board panel 13 of the center structure 6. Furthermore, the center structure 6 and the side structure 7 are held in a state where the inner flange portion 31 and the outer flange portion 32 are superimposed. In a state where the inner flange portion 31 and the outer flange portion 32 are not joined, the lateral bone members are attached so as to extend over the pair of left and right side structures 7. The structure is then attached to the transverse bone member. Thereby, since the process of arranging the structure is completed, the inner flange portion 31 and the outer flange portion 32 can be joined to form the joint portion 37.

  The material of the structural body 381 is preferably a material that does not easily deform or break even if stress caused by the collision acts on the structural body 381 through the toe board panel 13 or has high rigidity. It is good to be doing. Specifically, the structural body 381 may be formed of the same material as that of the skeletal member having high rigidity, for example, the A pillar 17 and the side sill 15 among the components of the vehicle body 1 shown in FIG. .

FIG. 5 shown next is a partially enlarged perspective view of the embodiment shown in FIG. 4 (C).
As shown in FIG. 5, the joint portion 37 between the toe board panel 13 and the A-pillar 17 protrudes forward and is exposed at a portion below the reinforcement member 19 for reinforcement. Note that FIG. 5 is an external view of the vehicle body from the left side, so the structural body 381 provided closer to the passenger compartment 3 than the toe board panel 13 is not shown.
Since the structural body 381 is provided at a position not interfering with the joint portion 37 and the reinforcing member 19 for reinforcement, the structural body 381 affects the joining state of the reinforcing member 19 and the A-pillar 17. I have not. That is, in the present invention, the structural body 381 can be attached so as to cover the joint portion 37 which is likely to hit the dropped front wheel without deteriorating the complementarity of the front upper member 18 by the stiffening member 19. .

FIG. 6 is a schematic cross-sectional view of the toe board panel 13 and members disposed therearound. As shown in FIG. 6, the toe board panel 13 defines a front chamber 2 in the front and a passenger compartment 3 in the rear.
The front chamber 2 is provided with a front upper member 18 extending forward and a stiffening member 19 for reinforcement.
In the passenger compartment 3, a toe board panel 13, an instrument panel 39, a steering support beam 40, a steering wheel 41, a connecting member 42, and a structural body 381 are provided. In the rear of the toe board panel 13, an area for accommodating equipment that can be operated by the occupant is provided. The instrument panel 39 is a member that covers the area, and is often molded of resin or the like. The steering support beam 40 is one of the members housed inside the instrument panel 39. The steering support beam 40 is a frame-like member that extends in the left-right direction and has a hollow substantially cylindrical shape. Both ends of the steering support beam 40 are fixedly connected to a pair of A-pillars (not shown in FIG. 6) provided on the left and right of the vehicle body 1. The steering wheel 41 is a member for operating the direction of forward and backward movement of the vehicle. The steering wheel 41 is connected to the steering support beam 40 via a connecting member 42 which is formed by combining appropriate members. Although not shown in FIG. 6, when the steering wheel 41 is operated, the contents of the operation are transmitted to the wheels, and various connecting members are assembled so that the wheels are directed in the direction reflecting the contents of the operation.
The steering support beam 40 is an example of a lateral bone member extending in the lateral direction in the passenger compartment in the present invention.

The structure 381 is connected to the steering support beam 40. The structural body 381 has a buffer 43 and a support 441. The buffer 43 hangs from the steering support beam 40. The support portion 441 extends forward from the lower end portion of the buffer portion 43 and supports the toe board panel 13. However, in the present invention, the structure may be fixed to the side of the passenger compartment, and may be connected to the fixed cross bone member in the passenger compartment as long as there is no hindrance to driving. The functions of the buffer 43 and the support 441 will be described later along with the description of FIG.
Although the buffer 43 shown in FIG. 6 is suspended substantially vertically from the steering support beam 40, in the present invention, the buffer 43 may extend obliquely forward or backward from the steering support beam. Further, although the support portion 441 shown in FIG. 6 extends obliquely downward from the lower end portion of the buffer portion 43 in the front lower side, in the present invention, the front horizontal direction is branched so as to be branched not from the end portion. It may extend to The structural body 381 is a bending member formed by bending between the buffer portion 43 and the support portion 441, but in the present invention, it may be a curved member in which the buffer portion and the support portion are connected by a curved surface. . Furthermore, in the present invention, the structure does not include the buffer portion 43, and a rod-like member or a hollow frame linearly extending from a fixed object such as the steering support beam 40 toward the passenger compartment side surface of the partition panel. It may be an annular member.
The front end portion of the support portion 441 is in contact with the surface of the toe board panel 13 on the passenger compartment side, that is, the rear surface of the toe board panel 13. Therefore, the structure body 381 supports the toe board panel 13 from the rear even if the front wheel FT shown by the broken line is dropped at the time of a collision and pushed in the direction of the white arrow.

In the present invention, for example, the end of the structure and the surface on the passenger compartment side of the partition panel may be joined, or a gap may be provided between the end of the structure and the partition panel. In the present invention, preferably, the end of the structure and the surface on the passenger compartment side of the partition panel are abutted or joined. For example, as in the embodiment shown in FIG. 6, when the front end portion of the support portion 43 in the structural body 381 abuts on the passenger compartment side surface of the toe board panel 13, the front end portion of the support portion 43 and the occupant of the toe board panel 13 The chamber side is always in contact with the surface. In this contact state, when the wheels FT and the like are pushed into the toe board panel 13, the toe board panel 13 is deformed toward the passenger compartment as compared with the case where the structure 381 is provided with a gap. There is no force contact with 381. Therefore, stress, impact, damage, deformation and the like do not occur in the toe board panel 13 when it comes in contact with the structure 381 from the non-contact state. In other words, by bringing the structural body 381 into contact with the toe board panel 13 in advance, it is possible to reduce unintended stress and impact acting on the toe board panel 13. Also in the case where the front end portion of the structure and the surface on the passenger compartment side of the partition panel are joined, it is possible to reduce unintended stress and impact acting on the partition panel. Examples of the unintended stress and impact include stress and impact which can cause the partition panel to be largely deformed or broken toward the passenger compartment, not stress and impact generated during normal traveling or the like.
Although FIG. 4C and FIG. 6 show only the structural body 381 on the left side of the vehicle body 1, a similar structural body 381 can be attached to the right side. That is, the structures 381 are a pair of members provided on the left and right sides.

Furthermore, when the end of the structure and the surface on the passenger compartment side of the partition panel are joined, the position of the partition panel with respect to the structure is fixed. While the structure is basically immobile even under stress and impact etc, the partition panel can be deformed. When the partition panel is deformed, the positional relationship between the portion where the end of the structure approaches or faces in the partition panel is deviated from the end of the structure. When the position of the partition panel relative to the structure is fixed, this positional relationship does not shift or is difficult to shift. If the positional relationship does not shift or does not shift easily, the structure suppresses the deformation of the partition panel even if the partition panel is about to be deformed by the wheels or the like being pushed into the partition panel. In addition, when the said positional relationship tends to shift, a stress acts on the joining site | part of a structure and a partition panel in a shear direction. Joints formed by spot welding often used in the manufacture of vehicles have good shear resistance performance. Therefore, when joining a structure and a partition panel, if it joins by spot welding, the difficulty of deformation of a partition panel can be improved.
When the end of the structure and the surface on the passenger compartment side of the partition panel are joined, the connection itself between the structure and the partition panel is the joint itself even if the stress related to the collision acts on the partition panel and the structure 381 Is preferably an embodiment having a joint strength which does not break or is hard to break, and, for example, welding which is frequently used at the time of manufacturing a vehicle can be adopted.

Next, the collision safety performance of the vehicle having the vehicle body 1 shown in FIG. 1 will be described with reference to FIGS.
First, FIG. 7 is an explanatory view of an example of the collision mode of the vehicle body 1.

The second automobile 52 collides with the first automobile 51 at a stop, for example, at a speed of 90 km from the front. The second automobile 52 collides with the outside of the pair of front side members 14 of the first automobile 51 and with the left front side member 14 in the collision example shown in FIG. 7. In such a collision, the second automobile 52 may cause the front wheel FT of the first automobile 51 to drop off the axle. When the front wheel FT falls off, the stress acting on the front wheel FT at the time of falling off becomes an inertial force directed rearward. Furthermore, the body of the second automobile 52, the parts dropped from the second automobile 52, the front wheels, etc. may have an inertial force that keeps pushing the front wheel FT of the first automobile 51 rearward. The dropped front wheel FT of the first automobile 51 may crush the joint portion 37.

  Subsequently, FIG. 8 is a schematic cross-sectional view at the time of a collision of a vehicle body shown as a comparative example. The structure body 381 shown in FIG. 4C is not provided in FIG. Since the same members as the embodiment shown in FIG. 4C are used except that the structural body 381 is not provided, the same reference symbols are attached, and the detailed description of the common members is omitted. The collision mode shown in FIG. 8 is an example of the case where a conventional vehicle collides in the mode shown in FIG.

  First, as shown in FIG. 8 (A), the dropped front wheel FT moves in the direction of the white arrow, that is, in the rear direction. The dropped front wheel FT is moving toward a joint 37 between the inner flange 31 and the outer flange 32. The joint 37 projects forward and does not attach a separate member, and therefore, when an interference interferes with the joint 37, stress from the interference directly acts on the joint 37.

Next, as shown in FIG. 8B, the dropped front wheel FT causes the joint portion 37 to break. When the joint portion 37 is broken, the joined state of the inner flange portion 31 and the outer flange portion 32 is released. Specifically, in spot welding generally used for manufacturing a vehicle, the joint is broken when a peeling force is applied to members joined by spot welding. Furthermore, when one joint location is torn off and torn, adjacent other junctions are often torn off sequentially to break. The dropped front wheel FT crushes the joint 37 by applying a stress in a backward direction to the joint 37. When the joint portion 37 is crushed, a stress that peels off the inner flange portion 31 and the outer flange portion 32 acts on the joint portion 37. Thereby, the joint portion 37 is broken.
The A-pillar 17 having the inner side panel 33 and the outer side panel 34 formed with the outer flange portion 32 is a member having high rigidity since it is one of the frame members of the vehicle body 1. Therefore, even if the outer flange portion 32 is deformed and broken due to the interference of the front wheel FT, the deformation, breakage and the like of the entire A-pillar 17 hardly occurs or does not occur. For example, as shown in FIG. 8 (B), the A-pillar 17 may remain in such a deformation that the front surface of the outer side panel 34 is slightly pushed backward.
Even if the joint portion 37 is deformed and broken and the A-pillar 17 is further deformed, there is a possibility that the front wheel FT is pushed into the toe board panel 13 if the force to be pushed to the rear of the dropped front wheel FT is maintained. Specifically, as shown in FIG. 8B, the dropped front wheel FT moves so as to push the toe board panel 13 into the passenger compartment 3. The front wheel FT moves rearward while deforming or breaking the inner flange portion 31, and deforms the toe board panel 13 so as to push it backward. When the rearward force of the dropped front wheel FT is large, a part of the front wheel FT may intrude into the passenger compartment 3 as shown in FIG. 8 (B).

As described above, in the case of the collision mode as shown in FIG. 7, for example, the dropped front wheel FT causes the joint portion 37 to break, deforms the toe board panel 13 into the passenger compartment 3, and further into the passenger compartment 3. It may invade.
When the joint portion 37 is broken, the passenger compartment 3 is difficult to be maintained in a sealed box shape. When the joint portion 37 is broken and the toe board panel 13 is further deformed, the passenger compartment 3 and the front compartment 2 communicate with each other, and the passenger compartment 3 is not maintained in a closed box shape.

  Here, with reference to FIG. 9, the case where the vehicle body 1 of FIG. 1 collides, which is an embodiment of the vehicle body structure of the vehicle according to the present invention, will be described. The collision mode shown in FIG. 9 is an example when the vehicle according to the present invention collides in the mode shown in FIG. FIG. 9 is a schematic cross-sectional view showing the joint 37 of the toeboard panel 13 and the left A-pillar 17 at the time of the collision of the vehicle body 1 shown in FIG.

FIG. 9A is a schematic cross-sectional view of the case where the dropped front wheel FT is pushed into the joint portion 37 between the inner flange portion 31 and the outer flange portion 32.
When the dropped front wheel FT moves in the direction of the white arrow due to the inertial force, the pressing force of the colliding object, etc., the front wheel FT may be pushed against the joint 37 as shown in FIG. 9A. There is.
As shown in FIG. 4C, in the present embodiment, a structural body 381 is provided at the rear of the toe board panel 13. Specifically, the front end portion of the support portion 441 in the structural body 381 is in contact with the rear surface of the toe board panel 13.

FIG. 9B is a schematic cross-sectional view of the case where the dropped front wheel FT starts to contact the joint portion 37. FIG.
As shown in FIG. 9, no separate member is attached to the joint 37, and the joint 37 is exposed. Therefore, when the dropped front wheel FT moves rearward, the front wheel FT comes in direct contact with the joint portion 37. Thus, the joint portion 37 directly receives stress from the front wheel FT. When the front wheel FT is pushed in with a large stress, the joint 37 which receives the stress directly may be compressed rearward and crushed.

  Here, even if the dropped front wheel FT contacts or crushes the joint portion 37, the pushed front wheel FT may not stop. That is, even if the front wheel FT contacts the joint portion 37 and causes the joint portion 37 to be stressed rearward, the front wheel FT may still have stress directed rearward. In this case, there may be considered a mode in which the front wheel FT pushed in largely changes the traveling direction and a mode in which the direction is not changed.

As a mode in which the front wheel FT largely changes the traveling direction, for example, when the front wheel FT does not exert stress on the toe board panel 13 and the A pillar 17 by being deviated to the outer side in FIG. It can be roughly divided into the case of going to the toe board panel 13 and the case of being deviated.
When the front wheel FT deviates to the outside, stress related to the collision does not act on the vehicle body 1, which is preferable.
When the front wheel FT deviates inward, there is a possibility that the joint portion 37 may be broken as shown in FIG. 8B and the toe board panel 13 may be pushed toward the passenger compartment 3 as in the prior art. In the present embodiment, the structural body 381 supports the toe board panel 13 from the passenger compartment 3 side. Therefore, the stress acting on the toe board panel 13 from the front wheels FT toward the inside of the passenger compartment 3 is received by the structural body 381 at the rear of the toe board panel 13.
When stress is applied to the structure 381, as shown in FIG. 6, the support 441 in proximity to or in contact with the toe board panel 13 is stressed. When the support 441 is stressed, the stress is transmitted to the buffer 43 extending upward from the rear end of the support 441. The stress acting on the support portion 441 is parallel or substantially parallel to the axis of the support portion 441. On the other hand, the stress acting on the buffer 43 is orthogonal or nearly orthogonal to the axis of the buffer 43, and is not at least parallel. In other words, the direction of the stress acting on the buffer 43 is the direction in which the buffer 43 bends backward. Therefore, when the support portion 441 and the buffer portion 43 have different extending directions, the structural body 381 can receive a part of the stress acting on the support portion 441 as a direction in which the buffer portion 43 bends. If the buffer 43 has the property of bending, the stress acting on the support 441 is attenuated by the backward bending of the buffer 43 and transmitted to a fixed object such as the steering support beam 40 or the like. Ru. The steering support beam 40 is often fixedly attached to the pair of left and right A pillars 17. The stress acting on the steering support beam 40 from the buffer 43 is transmitted to the A-pillar 17. Therefore, in the present embodiment, the stress applied to the structural body 381 is stressed by the support portion 441, damped by the buffer portion 43, and further dispersed to the steering support beam 40 and the A-pillar 17.
Therefore, even if the joint portion 37 is crushed by the front wheel FT, the toeboard panel 13 is not significantly deformed or broken toward the passenger compartment 3 side. That is, even if the joint portion 37 itself is broken due to crushing or the like, the structural body 381 can particularly prevent large deformation or breakage to the rear of the toe board panel 13, so the passenger compartment 3 is joined. It will not be in an open state starting from the part 37, or it will be difficult.

Moreover, as an aspect which the front wheel FT mentioned above does not change the advancing direction, it is possible that it will be in the state shown in FIG.9 (C). FIG. 9C is a schematic cross-sectional view of the case where the dropped front wheel FT starts to contact the toe board panel 13 and the A pillar 17. That is, the front wheel FT squeezes the joint portion 37 and further moves in the direction in which the joint portion 37 is squeezed. In this case, the front wheel FT exerts stress on the toe board panel 13 and the A pillar 17. Since the A-pillar 17 is a skeletal member having high rigidity, it is difficult to significantly deform or break. Since the structure 381 supports the toe board panel 13 to which stress can act from the rear, it does not significantly deform or break toward the passenger compartment 3 side or does not easily. Also in this case, as in the case where the front wheel FT is pushed into the toe board panel 13 described above, the stress applied to the structural body 381 is stressed by the support portion 441 and attenuated by the buffer portion 43, and further the steering support beam 40 And A pillars 17 are dispersed.
Therefore, even if the joint portion 37 is crushed by the front wheel FT, the toe board panel 13 is not significantly deformed or broken toward the passenger compartment 3 side. Therefore, even if the joint 37 itself is broken due to crushing or the like, the structural body 381 can prevent large deformation or breakage to the rear of the toe board panel 13, so that the joint 37 is used as a starting point. The passenger compartment 3 will not be largely open or difficult to open. In other words, by providing the structural body 381, even if the front wheel FT is directly pushed into the joint portion 37, the joint portion 37 can be crushed to such an extent that damage to the larger vehicle body 1 can be prevented. .

  The joint portion 37 is provided behind the front wheel FT pivotally supported by the vehicle body 1. Further, the joint portion 37 is provided so as to be positioned at least on the rear side of the rotation center of the front wheel FT. In the present invention, the joint portion is provided not only in the front wheel FT described above but also in the vicinity of a rear wheel (not shown). Therefore, the position of the joint is the front or the rear of the wheel, at least the front or the rear of the rotation center of the wheel. Such a position of the joint with respect to the wheel is such a position that the wheel is likely to be pushed in with a strong impact if the wheel falls off. In the present embodiment, a structural body 381 is provided so that a member extending from the joint portion 37, in particular, the toe board panel 13 is not significantly deformed or broken. The structure 381 can effectively prevent the toe board panel 13 from being largely deformed or broken toward the passenger compartment 3 and the passenger compartment 3 becoming open.

  Large deformation or breakage of the toe board panel 13 is one of the major causes of the passenger compartment 3 being in an open state starting from the joint portion 37. In the present embodiment, large deformation or breakage of the toe board panel 13 can be prevented by the structure 381. As a result, the passenger compartment 3 is easily maintained in a sealed box shape.

As described above, in the vehicle body structure of the present embodiment, it is possible to effectively suppress the deformation and breakage of the toe board panel 13, and to further enhance the collision safety performance of the vehicle.
Further, in the present embodiment, the welding operation of the joint portion 37 and the mounting operation of the structural body 381 do not require a special large-sized dedicated device, and a welding device or the like used in a normal vehicle manufacturing process is adopted. be able to. In particular, since the mounting operation of the structural body 381 is merely attaching the structural body 381 to the steering support beam 40 in which various members are assembled, a large change in the working process is not necessary. Further, since the structural body 381 is installed in an open area around the instrument panel 39 and the toe board panel 13, no major change of the vehicle body structure is required. Therefore, this embodiment can use the existing vehicle body manufacturing line as it is. Also, changes in the manufacturing process can be minimized.

The above-described embodiment is an example in which the present invention is applied to the toe board panel 13 of the center structure 6.
In addition to this, for example, the present invention may be applied to the rear bulkhead panel 26 of the center structure 6. By providing the structure on the passenger compartment side, even when the rear bulkhead panel 26 and the C-pillar 23 joint portion is pushed in by the rear wheel or the collision object in the event of a collision from the rear of the vehicle body 1. This makes it difficult for the passenger compartment 3 to be in the open state.

[Modification of structure]
In the embodiment described above, the structural body 381 is disposed inward of the joint portion 37 in the width direction of the vehicle body 1. In the vehicle body structure of the vehicle according to the present invention, the structure can adopt various shapes and mounting positions as long as the partition panel is supported from the passenger compartment side. FIGS. 10A to 10C show modifications of the structure of the vehicle body structure of the vehicle according to the present invention.
The differences between each of the embodiments shown in FIGS. 10A to 10C and the embodiment shown in FIG. 4C are the shape of the structure and the mounting position. Since the same members as the embodiment shown in FIG. 4C are used except for the differences, the same reference numerals are given and detailed description will be omitted.

FIG. 10A shows an embodiment in which a structure 382 is attached.
Specifically, the structures 382 shown in FIG. 10A and the structures 381 shown in FIG. 4C have substantially the same shape. The difference between the structure 382 and the structure 381 is the position where it is provided. The structural body 381 is provided inside the joint portion 37 in the width direction of the vehicle body 1, whereas the structural body 382 is behind the joint portion 37 of the vehicle body 1 and the inner side panel 33 of the A pillar 17. Provided in contact with the inner surface of the
In the present invention, the structure adopts at least one of an aspect disposed inside the joint in the width direction of the vehicle body, and an aspect disposed on the passenger compartment side of the joint along the side panel. be able to. The embodiment shown in FIG. 10A is an example of an aspect in which the structure is disposed along the side panel on the passenger compartment side of the joint. In the present invention, an embodiment in which the structure is disposed along the side panel also includes an embodiment in which a portion of the structure and a portion of the side panel are in contact or joined. .
The support portion 442 in the structure 382 extends along the inner side panel 33 and abuts on the surface of the inner side panel 33 on the passenger compartment 3 side. Similar to the embodiment shown in FIG. 6, a buffer is connected to the rear of the structure 382 (not shown in FIG. 10A), in particular to the rear end of the support 442, and the steering support beam 40 etc. It is attached to a fixed object. The front end portion of the support portion 442 in the structural body 382 is in contact with the surface of the toe board panel 13 on the passenger compartment 3 side.

Since the structure 382 abuts not only on the toe board panel 13 but also on the inner side panel 33 of the A pillar 17, the large deformation and breakage of the toe board panel 13 and the inner side panel 33 toward the passenger compartment 3 can be achieved. Can be prevented.
Furthermore, like the structure 381, the structure 382 is preferably formed of a material that does not easily cause large deformation and breakage. That is, the structural body 382 is a highly rigid member that abuts along the inner side panel 33. Further, as described above, since the A-pillar 17 is a frame member of the vehicle body 1, it has high rigidity. Thereby, the inner end surface of the structural body 382, particularly the right side surface of the support portion 442, the outer end surface of the A-pillar 17, particularly the left side surface of the outer side panel 34 can be regarded as one high rigidity member. That is, the embodiment shown in FIG. 10A is, for example, an embodiment in which the A-pillar expanded inward by the size in the left-right direction in the support portion 442 is arranged with respect to the embodiment shown in FIG. It can be considered that In this embodiment, the joint portion 37 is disposed on the front front surface of the A-pillar expanded inward. Therefore, according to this embodiment, for example, when the front wheel dropped off with respect to the joint portion 37 is directly pushed in, the inwardly expanded A-pillar receives stress. Most of the stress is dispersed and absorbed in the A-pillar 17 and the structure 382 by the stress applied to the A-pillar 17 and the structure 382 having high rigidity. As a result, a large open state of the passenger compartment 3 starting from the joint portion 37 does not occur or hardly occurs, which is preferable.
Although only the structural body 382 on the left side of the vehicle body 1 is shown in FIG. 10A, a similar structural body 382 can be attached to the right side. That is, the structures 382 are a pair of members provided on the left and right sides.
The embodiment shown in FIG. 10A is particularly suitable in the case where a collision mode in which wheels such as falling front wheels are directly pushed into the joint portion is mainly assumed.

FIG. 10B shows an embodiment in which the structure 383 is attached.
Specifically, the difference between the structural body 383 shown in FIG. 10B and the structural body 381 shown in FIG. 4C is the position and shape provided. The structural body 381 is provided inside the joint portion 37 in the width direction of the vehicle body 1, whereas the structural body 383 is behind the joint portion 37 and the inner side surface of the inner side panel 33 of the A pillar 17. It is provided in contact with the Further, the extending direction of the support portion and the tip shape of the support portion are also different.
The embodiment shown in FIG. 10 (B) is an example of an aspect in which the structure is disposed along the side panel on the occupant compartment side of the joint.
The support portion 443 in the structural body 383 extends toward the joint portion 37 from the inside of the joint portion 37 in the width direction of the vehicle body 1. A second support 453 is attached to the tip of the support 443. The second support 453 is a plate member having a substantially L-shaped cross section, and is fixedly attached to the front end of the support 443. The second support portion 453 is in contact with a surface of the toe board panel 13 on the passenger compartment 3 side and a surface of the inner side panel 33 on the passenger compartment 3 side. Since the joint portion 37 extends in the vertical direction, it is preferable that the second support portion 443 extend in the vertical direction along the joint portion 37 on the passenger compartment 3 side. Thereby, even if the dropped front wheel or the like is pushed into any position in the vertical direction in the joint portion 37, the structural body 383 can receive stress via the second support portion 453. Similar to the embodiment shown in FIG. 6, a buffer is connected to the rear of the structure 383 not shown in FIG. 10 (B), in particular to the rear end of the support 443 so that the steering support beam 40 etc. It is attached to a fixed object.

Since the structure 383 abuts not only on the toe board panel 13 but also on the inner side panel 33 of the A pillar 17, large deformation and breakage of the toe board panel 13 and the inner side panel 33 toward the passenger compartment 3 can be achieved. Can be prevented.
Furthermore, when stress acts on the joint portion 37 from the front wheel or the like, the support portion 443 of the structural body 383 can also exhibit the function as a buffer portion. More specifically, the support portion 443 extending to the rear of the second support portion 453 extends from the inside of the joint portion 37 toward the joint portion 37 in the width direction of the vehicle body 1 as described above. That is, the support portion 443 is inclined with respect to the front-rear direction and extends outward. Therefore, when the front wheel or the like is directly pushed into the joint portion 37, first, the second support portion 453 receives stress in the passenger compartment 3. When the second support 453 is stressed, the stress is transmitted to the support 443 on which the second support 453 is fixedly attached. At this time, stress substantially parallel to the front-rear direction is transmitted from the second support 453 to the support 443. Since the support portion 443 is inclined with respect to the front and rear direction, the stress transmitted to the support portion 443 is a stress acting in the direction in which the support portion 443 bends backward, and a direction in which the support portion 443 is pushed backward It works in divided into the acting stress. Therefore, if the support portion 443 has the property of bending, the buffer portion connected to the rear end portion of the support portion 443 in a state where the stress acting in the direction in which the support portion 443 bends is attenuated (see FIG. Stress is transmitted to 10 (B) (not shown). Therefore, in the embodiment shown in FIG. 10B, the support portion 443 exerts the same function as the buffer portion, and stress can be attenuated also in the buffer portion connected to the support portion 443. The stress acting on the second support 453 is transmitted to a fixed object such as the steering support beam 40 after being attenuated by the backward deflection of the support 443 and the buffer 43. As a result, a large open state of the passenger compartment 3 starting from the joint portion 37 does not occur or hardly occurs, which is preferable.
Although only the structural body 383 on the left side of the vehicle body 1 is shown in FIG. 10B, a similar structural body 383 can be attached to the right side. That is, the structural bodies 383 are a pair of members provided on the left and right sides.
The embodiment shown in FIG. 10 (B) is particularly suitable in the case where a collision mode in which wheels such as falling front wheels are directly pushed into the joint portion is mainly assumed.

FIG. 10C shows an embodiment in which the structure 384 is attached.
Specifically, the difference between the structure 384 shown in FIG. 10C and the structure 381 shown in FIG. 4C is the shape. While the support portion 441 in which the structure body 381 has a rod shape is in direct contact with the toe board panel 13, the structure body 384 has a second support portion 454 of the plate-like member between the support portion 444 and the toe board panel 13. It is interposed.
In the embodiment shown in FIG. 10C, the structure abuts or is joined to the surface on the passenger compartment side of the partition panel, and is disposed along the side panel on the passenger compartment side of the joint portion. It is an example of an aspect.
The support portion 444 in the structural body 384 is disposed inside the joint portion 37 in the width direction of the vehicle body 1 as in the support portion 441 of the structural body 381, and is parallel or substantially parallel to the front-rear direction. At the front end portion of the support portion 444, a second support portion 454 extending in the vertical direction and the left and right direction along the toe board panel 13 is attached. The second support portion 454 is in contact with a portion of the toe board panel 13 on the side of the passenger compartment 3 from the inside of the joint portion 37 in the width direction of the vehicle body 1 to the rear of the joint portion 37. Therefore, when the front wheel FT or the like dropped off within the range where the second support portion 454 is in contact in the toe board panel 13, the second support portion 454 can receive stress. The stress received by the second support 454 is transmitted to the support 444. The stress received by the support 444 is transmitted to a buffer (not shown in FIG. 10C) connected to the rear end of the support 444. Similar to the structure 381 shown in FIGS. 4C and 6, the stress received by the buffer portion of the structure 384 is transmitted to the load such as the steering support beam 40 or the like in which the buffer is bent backward. And the stress being dispersed. Therefore, the structural body 384 can receive stress in a wide range in the toe board panel 13 as compared with the embodiment shown in FIG. 4 (C). As a result, the possibility of the toeboard panel 13 being largely deformed and broken toward the passenger compartment 3 can be further reduced, as compared with the embodiment shown in FIG. 4C. That is, it is preferable because a large open state of the passenger compartment 3 starting from the joint 37 does not occur or hardly occurs.
Although only the structural body 384 on the left side of the vehicle body 1 is shown in FIG. 10C, a similar structural body 384 can be attached to the right side. That is, the structures 384 are a pair of members provided on the left and right sides.
The embodiment shown in FIG. 10C is particularly suitable in the case where a collision mode in which wheels such as falling front wheels are directly pushed into the joint portion is mainly assumed.

The above-described embodiments are examples in which the present invention is applied to a car body 1 of a three-box structure automobile.
In addition to this, for example, the present invention can be applied to a vehicle such as a one-box structure car, a two-box structure car, a truck, a bus, a train, an aircraft, and the like. In particular, the present invention can be suitably applied to a vehicle manufactured by joining a pair of side structures 7 on both sides in the width direction of the center structure 6 of the vehicle body 1.
