Technical Field

[0002] In the prior art, in order to resist the impact force generated when the front of the vehicle is hit, a floor longitudinal beam connected to the root of the front longitudinal beam of the vehicle is usually arranged at the lower end of the vehicle floor, so that the impact force of the front of the vehicle can be transmitted from the front longitudinal beam of the vehicle to the floor longitudinal beam of the vehicle, thereby reducing the degree of stress damage to the front panel of the vehicle connected to the front longitudinal beam of the vehicle and ensuring the personal safety of the vehicle occupants.

[0003] However, with the development of vehicle technology, the utilization rate of new energy vehicles has gradually increased. In the specific structure of new energy vehicles, the power battery used to provide driving force is installed at the bottom of the vehicle floor, which makes it impossible to install the vehicle floor longitudinal beam at the bottom of the vehicle floor.

DETAILED DESCRIPTION

[0037] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0038] It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. In addition, the term "and / or" herein is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The terms "first" and "second" in the description and claims of the embodiments of the present application are used to distinguish different objects, rather than to describe a specific order of objects.

[0039] First, the terms involved in this application are explained as follows:

[0040] (1) Dual-mode new energy vehicle: a vehicle that can use two different energy sources at the same time; the two different energy sources can be fuel energy and electric energy respectively.

[0041] Specifically, when the vehicle is in pure electric mode, the battery pack can be used to power the vehicle through the electric motor; when the vehicle is in hybrid mode, the battery pack and the fuel engine can be used to power the vehicle at the same time;

[0042] (2) 25% offset collision: refers to a small overlap collision of vehicles; specifically, in the collision test, the front section of the vehicle body collides with the obstacle with a width of 25%.

[0043] At present, when the front of a vehicle is hit head-on or with a 25% offset, the deformation of the front structure of the vehicle body can absorb part of the impact energy generated during the collision, but the remaining impact energy can still be directly transmitted to the front panel of the vehicle, thereby causing deformation of the front panel. In the prior art, in order to resist the impact force generated when the front of the vehicle is hit, a floor longitudinal beam connected to the root of the front longitudinal beam of the vehicle is usually arranged at the lower end of the vehicle floor, so that the impact force of the front of the vehicle can be transmitted from the front longitudinal beam of the vehicle to the floor longitudinal beam of the vehicle, thereby reducing the degree of damage to the front panel of the vehicle connected to the front longitudinal beam of the vehicle, and ensuring the personal safety of the vehicle occupants.

[0044] However, with the development of vehicle technology, the utilization rate of new energy vehicles has gradually increased. In the specific structure of new energy vehicles, the power battery used to provide driving force is installed at the bottom of the vehicle floor, which makes it impossible to install the vehicle floor longitudinal beam at the bottom of the vehicle floor. Therefore, when the front of the vehicle is impacted, the degree of damage to the front panel of the vehicle cannot be reduced.

[0045] Based on this, an embodiment of the present application provides a vehicle body structure 10, which can transmit the external impact force to the vehicle body A-pillar 12 and the vehicle body door sill 13 respectively through the connection state of the front longitudinal beam 11. When the vehicle body receives external impact force, the external impact force can be transmitted to the vehicle body A-pillar and the vehicle body door sill 13 respectively, thereby reducing the degree of damage to the vehicle body under the impact force and ensuring the stability of the vehicle body structure.

[0046] Figure 1 The exploded structural diagram of the vehicle body structure 10 provided in the embodiment of the present application is shown in one perspective. Figure 1 As shown, the vehicle body structure 10 includes: a front longitudinal beam 11, a vehicle body A-pillar 12 and a vehicle body rocker 13; wherein the front longitudinal beam 11 includes a first cavity 111 and a second cavity 112, the first cavity 111 is connected to the vehicle body A-pillar 12, and the second cavity 112 is connected to the vehicle body rocker 13.

[0047] In one possible implementation, Figure 2 This is a schematic diagram of an exploded structure of the vehicle body structure 10 provided in another perspective of the embodiment of the present application. Figure 2 As shown, the front longitudinal beam 11 is formed by connecting the vehicle body longitudinal beam inner plate 113 and the vehicle body cover plate 114.

[0048] For example, the vehicle body longitudinal beam inner plate 113 and the vehicle body cover plate 114 may be connected by overlapping to form the first cavity 111 and the second cavity 112. For example, the overlapping method may include welding, bolting or gluing.

[0049] Specifically, when the overlapping method is welding, the edge of the body longitudinal beam inner plate 113 and the body sealing plate 114 can be welded; when the overlapping method is bolt connection, the edge of the body longitudinal beam inner plate 113 and the body sealing plate 114 can be fixed by fixing components such as bolts or screws; when the overlapping method is gluing, the edge of the body longitudinal beam inner plate 113 and the body sealing plate 114 can be bonded together by glue of special material.

[0050] For example, Figure 2 As shown, the rear structure of the front longitudinal beam 11 can be formed by connecting the rear section of the left front cover plate of the vehicle body and the rear section of the left longitudinal beam inner plate of the vehicle body.

[0051] In one possible implementation, Figure 2 As shown, the front longitudinal beam 11 can be overlapped with the body A-pillar 12 and the body door sill 13 respectively through the body longitudinal beam inner plate 113, so as to realize the connection between the first cavity 111 and the second cavity 112 and the body A-pillar 12 and the body door sill 13 respectively. The first cavity 111 and the second cavity 112 are arranged in sequence along the height direction of the vehicle.

[0052] In the embodiment of the present application, based on the connection status of the first cavity 111 and the second cavity 112 with the vehicle body A-pillar 12 and the vehicle body door sill 13 respectively, the front longitudinal beam 11 can disperse and transmit the external impact force from the first cavity 111 and the second cavity 112 to the vehicle body A-pillar 12 and the vehicle body door sill 13 respectively when receiving the external impact force.

[0053] For example, Figure 2 As shown, the first cavity 111 can be connected to the body A-pillar 12 through the connection state between the body longitudinal beam inner panel 113 and the body A-pillar inner panel 121; the second cavity 112 can be connected to the body door sill 13 through the connection state between the body longitudinal beam inner panel 113 and the body door sill inner panel 133.

[0054] In a possible implementation, the end of the front longitudinal beam 11 close to the front of the vehicle can also be connected to the front anti-collision beam of the vehicle body. Figure 3 FIG. 1 is a schematic diagram of an exploded structure of a beam structure 11 provided in an embodiment of the present application from one perspective. Figure 3 As shown, the front end of the front longitudinal beam 11 is connected to the front anti-collision beam 301 of the vehicle body.

[0055] In the embodiment of the present application, based on the connection state between the front anti-collision beam 301 and the front longitudinal beam 11 , the impact force from the front of the vehicle body can be dispersed from the front anti-collision beam 301 to the first cavity 111 and the second cavity 112 of the front longitudinal beam 11 .

[0056] It should be noted that if Figure 3 As shown, since the outside of the first cavity 111 and the second cavity 112 is the rear section of the vehicle body cover plate 114, and the rear section of the vehicle body cover plate 114 is arranged at the side rear part of the front tire of the vehicle, in order to make full use of the gap between the vehicle tire envelope and the vehicle body, the cross-section of the rear section of the vehicle body cover plate 114 is a wavy cross-section; wherein, the wavy cross-section can be expressed as an "M"-shaped cross-section.

[0057] For example, Figure 4 FIG. 1 is a schematic diagram of an exploded structure of the beam structure 11 provided in an embodiment of the present application from another perspective. Figure 4 As shown, the first cavity 111 is composed of the vertical surface 401 of the body longitudinal beam inner panel 113 in the body width direction (i.e., Y direction), the first horizontal surface 402 of the body longitudinal beam inner panel 113 in the body length direction (i.e., X direction), and the upper part 403 of the body sealing plate 114; the second cavity 112 is composed of the vertical surface 401 of the body longitudinal beam inner panel 113 in the body width direction (i.e., Y direction), the second horizontal surface 404 of the body longitudinal beam inner panel 113 in the body length direction (i.e., X direction), and the lower part 405 of the body sealing plate 114.

[0058] It should be noted that the first cavity 111 and the second cavity 112 can be a hollow cavity structure or a solid integral structure; no specific limitation is made here.

[0059] A vehicle body structure 10 provided in an embodiment of the present application can transmit the external impact force from the beam structure 11 to the vehicle body A-pillar 12 and the vehicle body door sill 13 respectively when the vehicle body receives an external impact force, thereby reducing the degree of damage to the vehicle body structure under the action of the external impact force to a certain extent and ensuring the stability of the vehicle body structure.

[0060] In another embodiment of the present application, other structural components of the vehicle body structure 10 are also introduced. Exemplarily, the vehicle body structure 10 further includes a support component 14 . Figure 5 FIG. 1 is a schematic diagram of an exploded structure of the vehicle body structure 10 provided in an embodiment of the present application from another perspective. Figure 5 As shown, the support assembly 14 is disposed in the cavity of the vehicle body A-pillar 12 and is disposed corresponding to one end of the first cavity 111 .

[0061] Exemplarily, the support assembly 14 may be disposed on the vehicle body A-pillar 12 , and the connection length between the support assembly 14 and the vehicle body A-pillar 12 may match the opening size of one end of the first cavity 111 .

[0062] In a possible implementation, a projection of the first cavity 111 in the length direction of the vehicle may at least partially overlap with a projection of the support assembly 14 in the length direction of the vehicle.

[0063] In the embodiment of the present application, the first cavity 111 can enhance its own stability by projecting overlapping support components 14 in the length direction of the vehicle.

[0064] In a possible implementation, the support assembly 14 can be disposed on both the inner and outer sides of the A-pillar inner panel 121 of the vehicle body. Exemplarily, the support assembly 14 can be disposed at a position corresponding to the opening of the first cavity 111 on the outer side of the A-pillar inner panel 121 of the vehicle body. The support assembly 14 can be an A-pillar inner panel support plate; for example, it can be a box-shaped component.

[0065] Exemplarily, the connection size between the support assembly 14 and the vehicle body A-pillar inner plate 121 may match the connection size between the first cavity 111 and the vehicle body A-pillar inner plate 121. The support assembly 14 and the vehicle body A-pillar inner plate 121 may be connected by welding.

[0066] For example, the length of the welded edge between the support assembly 14 and the A-pillar inner panel 121 of the vehicle body in the vehicle height direction may be the same as the connection length between the first cavity 111 and the A-pillar inner panel 121 of the vehicle body in the vehicle height direction. In other words, the upper and lower welded edges of the support assembly 14 in the vehicle height direction may correspond to the connection edges between the first cavity 111 and the A-pillar inner panel 121 of the vehicle body.

[0067] In the embodiment of the present application, the stability of the vehicle body A-pillar inner panel 121 can be enhanced by the support assembly 14 on the vehicle body A-pillar inner panel 121, thereby enhancing the stability of the first cavity 111 connected to the vehicle body A-pillar inner panel 121.

[0068] In another embodiment of the present application, a specific arrangement of the support assembly 14 is also introduced. Exemplarily, the arrangement direction of the support assembly 14 is at an angle to the length direction of the vehicle body, and the arrangement height of the support assembly 14 decreases along the length direction of the vehicle.

[0069] In one possible implementation, the support assembly 14 can be arranged to be higher in the front and lower in the rear along the length direction of the vehicle body based on the fact that the upper and lower welding edges of the support assembly 14 in the vehicle height direction correspond to the connection edges of the first cavity 111 and the A-pillar inner panel 121 of the vehicle body.

[0070] For example, when the front part of the vehicle body is subjected to force, the force transmitted from the front part of the vehicle body to the front longitudinal beam 11 can be transmitted to the vehicle body door sill 13 at the lower rear of the vehicle body through the support assembly 14 .

[0071] Specifically, Figure 6 FIG. 1 is a schematic diagram of an exploded structure of the vehicle body structure 10 provided in an embodiment of the present application from another perspective. Figure 6 As shown, when the front part of the vehicle body is subjected to force, the force transmitted from the front part of the vehicle body to the upper part of the front longitudinal beam 11 can be transmitted to the vehicle body door sill 13 by the upper welding edge of the support assembly 14; when the front part of the vehicle body is subjected to force, the force transmitted from the front part of the vehicle body to the lower part of the front longitudinal beam 11 can also be transmitted to the vehicle body door sill 13 by the lower welding edge of the support assembly 14.

[0072] In the embodiment of the present application, by setting the support component 14 in a form of high at the top and low at the bottom along the length direction of the vehicle body, when the front part of the vehicle body is hit, the impact force generated by the collision can be transmitted to the door sill 13 of the vehicle body through the support component 14, thereby reducing the transmission force value of the impact force of the front part of the vehicle body to the upper column of the vehicle body A-pillar 12, reducing the possibility of bending of the vehicle body A-pillar 12 during a head-on collision or an offset collision, and further ensuring the safety of the occupants in the vehicle.

[0073] In another embodiment of the present application, a specific structural component of the vehicle body door sill 13 is also introduced. For example, Figure 7FIG. 1 is a schematic diagram of an exploded structure of the vehicle body structure 10 provided in an embodiment of the present application from another perspective. Figure 7 As shown, a housing cavity 131 is formed in the body rocker 13, and a reinforcing beam 1311 is arranged in the housing cavity 131. The housing cavity 131 can be formed by connecting a body rocker inner plate 133 and a body rocker outer plate 134.

[0074] In the embodiment of the present application, a body rocker reinforcement beam 1311 may be provided in the accommodating cavity 131 of the body rocker 13 to improve the structural stability of the body rocker 13 .

[0075] In a possible implementation, a body rocker reinforcement beam 1311 may be disposed along the length direction of the vehicle body in the accommodating cavity 131 formed by the body rocker inner panel 133 and the body rocker outer panel 134 .

[0076] For example, Figure 8 FIG. 1 is a schematic diagram of an exploded structure of the vehicle body structure 10 provided in an embodiment of the present application from another perspective. Figure 8 As shown, the body rocker inner plate 133 can form a receiving cavity 131 with the body rocker outer plate 134; wherein the body rocker inner plate 133 and the body rocker outer plate 134 are respectively connected to the body cover plate 114. It should be noted that the design between the rear section of the body cover plate 114 and the tire 801 meets the minimum clearance requirement.

[0077] For example, the length of the rocker reinforcement beam 1311 may match the length of the rocker inner panel 133 or the rocker outer panel 134 .

[0078] In a possible implementation, a projection of the second cavity 112 in the vehicle width direction at least partially overlaps with a projection of the reinforcing beam 1311 in the vehicle width direction.

[0079] Exemplarily, when the second cavity 112 is subjected to an external impact force, the second cavity 112 may be supported by the reinforcing beam 1311 that overlaps with the projection of the second cavity 112 in the vehicle width direction.

[0080] For example, when the front part of the vehicle body is subjected to a 25% offset collision, Figure 8 As shown, the tire 801 may first contact the body rocker 13 to absorb the energy generated during the collision through the accommodating cavity 131 and the deformation of the body rocker reinforcement beam 131 in the accommodating cavity 131, thereby reducing the collision energy transmitted to the front panel of the body.

[0081] In another embodiment of the present application, other structural components of the vehicle body rocker 13 are also introduced. For example, Fig. 9 FIG. 1 is a schematic diagram of an exploded structure of the vehicle body structure 10 provided in an embodiment of the present application from another perspective. Fig. 9As shown, a body rocker sealing plate 132 is provided at one end of the body rocker 13 close to the front longitudinal beam 11 ; the body rocker sealing plate 132 is respectively connected to the body rocker inner plate 133 and the body rocker outer plate 134 .

[0082] In the embodiment of the present application, the body rocker sealing plate 132 can provide support for the accommodating cavity 131 inside the body rocker 13. Specifically, the body rocker sealing plate 132 is connected to the body A-pillar inner plate 121, the body A-pillar outer plate 122, the body rocker inner plate 133, the body rocker outer plate 134 and the body sealing plate 114 respectively.

[0083] In one possible implementation, the setting area of ​​the body rocker cover 132 can match the area of ​​the accommodating cavity 131, and then the body A-pillar inner panel 121, the body A-pillar outer panel 122, the body rocker inner panel 133 and the body cover 114 can be connected through the body rocker cover 132.

[0084] For example, Fig. 9 As shown, the vertical surface 901 of the body rocker cover plate 132 in the length direction of the body (i.e., the X direction) overlaps with the front connecting plate 902 of the body rocker inner panel 133 and the rear section 903 of the body cover plate 114 respectively; the vertical surface 904 of the body rocker cover plate 132 in the height direction of the body (i.e., the Z direction) overlaps with the body A-pillar outer panel 122 and the connecting surface 905 between the body rocker outer panel 134 and the body rocker cover plate 132 respectively; the vertical surface 906 of the body rocker cover plate 132 in the width direction of the body (i.e., the Y direction) overlaps with the body A-pillar outer panel 122 and the body rocker outer panel 134 respectively.

[0085] In the embodiment of the present application, the overlapping form of the body door sill 13 can be changed to an overlapping form along the length direction of the body (i.e., the X direction) by connecting the body door sill sealing plate 132 to the body A-pillar inner panel 121, the body A-pillar outer panel 122, the body door sill inner panel 133 and the body sealing plate 114 respectively. Therefore, when the front part of the body is subjected to a 25% offset collision, the body door sill 13 located on the side of the body is effectively avoided from cracking along the width direction of the body (i.e., the Y direction), thereby improving the collision performance of the body door sill 13.

[0086] In addition, the body sill sealing plate 132 can improve the sealing degree of the accommodating cavity 131, and at the same time increase the cross-sectional area of ​​the body sill 13 in the length direction of the body (i.e., X direction), so that one end of the front longitudinal beam 11 connected to the body sill 13 is more stable, thereby improving the stability of the front longitudinal beam 11.

[0087] For example, Fig.10 1 is a schematic diagram of the force transmission of the vehicle body structure 10 provided in the embodiment of the present application. Fig.10As shown, the connection 1001 between the vehicle body cover plate 114 and the vehicle body rocker cover plate 132 , the vehicle body longitudinal beam inner plate 113 and the vehicle body A-pillar inner plate 121 can form a cavity structure 1002 .

[0088] Specifically, when the front part of the vehicle body is subjected to a head-on collision, the collision impact force generated can be first transmitted from the front part of the vehicle body to the cavity structure 1002 through the front longitudinal beam 11, and then transmitted to the vehicle body door sill 13 through the cavity structure 1002, and then transmitted to the rear part of the vehicle body; and when the front part of the vehicle body is subjected to an offset collision, the collision impact force generated can be directly transmitted from the tire 801 to the vehicle body door sill 13, and then transmitted to the rear part of the vehicle body.

[0089] It should be noted that in order to allow most of the collision energy generated during the collision to be transmitted to the body door sill 13 through the cavity structure 1002, the overlap between the cavity structure 1002 and the body door sill 13 in the length direction of the body (i.e., the X direction) needs to be increased as much as possible. Therefore, the length L of the cavity structure 1002 in the length direction of the body (i.e., the X direction) needs to be increased.

[0090] In another embodiment of the present application, other structural components of the vehicle body structure 10 are also introduced. For example, Fig.11 FIG. 1 is a schematic diagram of an exploded structure of the vehicle body structure 10 provided in an embodiment of the present application from another perspective. Fig.11 As shown, the vehicle body structure 10 further includes a reinforcement member 15 ; wherein the vehicle body rocker reinforcement beam 1311 can be connected to the vehicle body A-pillar inner panel 121 through the reinforcement member 15 .

[0091] In the embodiment of the present application, the reinforcement member 15 can be used to enhance the tightness of the connection between the body A-pillar inner panel 121, the body rocker cover plate 132 and the body rocker reinforcement beam 1311 to enhance the stability when different structures are connected.

[0092] In one possible implementation, Fig.11 As shown, a reinforcement member 15 may be provided at the connection position between the front end of the vehicle body rocker reinforcement beam 1311 and the vehicle body A-pillar inner panel 121; for example, the reinforcement member 15 may be a bolt assembly that can further ensure the welding effect.

[0093] In a possible implementation, based on the connection state between the body rocker reinforcement beam 1311 and the body A-pillar inner panel 121, a viscous substance may be filled between the body rocker reinforcement beam 1311 and the body A-pillar inner panel 121, thereby further increasing the connection strength between the body rocker reinforcement beam 1311 and the body A-pillar inner panel 121. For example, the viscous substance may be structural adhesive.

[0094] In the embodiment of the present application, the connection strength between the body rocker reinforcement beam 1311 and the body A-pillar inner panel 121 can be ensured by the above-mentioned reinforcement member 15 and the adhesive material to ensure the stability of the body rocker 13.

[0095] In another embodiment of the present application, a connection state of a part of the vehicle body structure 10 is also introduced. Exemplarily, the vehicle body cover plate 114 is connected to the vehicle body A-pillar inner plate 121 by at least one set of reinforcement members 15; wherein a set of reinforcement members 15 includes two reinforcement members 15 arranged along the width direction of the vehicle body.

[0096] In the embodiment of the present application, the connection strength between the vehicle body cover plate 114 and the vehicle body A-pillar inner plate 121 can be enhanced by at least one set of reinforcement members 15 to reduce the probability of the vehicle body A-pillar 12 breaking during a collision of the vehicle body.

[0097] In a possible implementation, the vehicle body cover plate 114 and the vehicle body A-pillar inner plate 121 may be connected by at least one set of reinforcement members 15. The set of reinforcement members 15 may include two reinforcement members 15 arranged along the width direction of the vehicle body.

[0098] It should be noted that each reinforcement member 15 may correspond to one welding point. That is, there is at least one set of welding points between the vehicle body cover plate 114 and the vehicle body A-pillar inner plate 121, and a set of reinforcement members 15 is correspondingly arranged on each set of welding points. Among them, a set of welding points may include two welding points along the width direction of the vehicle body.

[0099] In a possible implementation, a projection of the reinforcement 15 in the vehicle width direction at least partially overlaps with a projection of the second cavity 112 in the vehicle width direction.

[0100] For example, Fig.12 FIG. 1 is a schematic diagram of an exploded structure of the vehicle body structure 10 provided in an embodiment of the present application from another perspective. Fig.12 As shown, there are multiple groups of welding points 1201 at the connection between the vehicle body cover plate 114 and the vehicle body A-pillar inner plate 121. Each group of welding points includes two welding points 1201 arranged along the width direction of the vehicle body.

[0101] In the embodiment of the present application, the double-row welding points 1201 and the double-row reinforcement members 15 at the connection between the body cover plate 114 and the body A-pillar inner plate 121 can be used to enhance the stability strength of the connection between the body A-pillar 12 and the body door sill 13, thereby avoiding the breakage of the body A-pillar 12.

[0102] In another embodiment of the present application, the specific structure of the front longitudinal beam 11 is also introduced. Exemplarily, the front longitudinal beam 11 is a hollow structure.

[0103] In a possible implementation, the front longitudinal beam 11 may be configured as a hollow structure to form a double cavity structure composed of the first cavity 111 and the second cavity 112 .

[0104] In the embodiment of the present application, the projection of the first cavity 111 in the vehicle width direction at least partially overlaps with the projection of the body A-pillar 12 and the body door sill 13 in the vehicle width direction, so that when the vehicle is subjected to external impact force, the first cavity 111 can transfer the external impact force laterally to the body A-pillar 12 and the body door sill 13, thereby enabling the body structure 10 to have better lateral force transmission.

[0105] For example, Fig.13 FIG. 1 is another schematic diagram of force transmission of the vehicle body structure 10 provided in an embodiment of the present application. Fig.13 As shown, when the front part of the vehicle body is subjected to a head-on collision or a 25% offset collision, the front anti-collision beam 301 of the vehicle body transfers the collision energy to the first cavity 111 and the second cavity 112 respectively through the front longitudinal beam 11; then, the first cavity 111 transfers the received collision energy to the vehicle body A-pillar 12 connected to itself, and the second cavity 112 transfers the received collision energy to the vehicle body door sill 13 connected to itself.

[0106] A vehicle body structure 10 provided in an embodiment of the present application can transmit the external impact force from the beam structure 11 to the vehicle body A-pillar 12 and the vehicle body door sill 13 respectively when the vehicle body receives an external impact force, thereby reducing the degree of damage to the vehicle body structure under the action of the external impact force to a certain extent and ensuring the stability of the vehicle body structure.

[0107] In another embodiment of the present application, a vehicle is provided. Exemplarily, the vehicle includes the vehicle body structure 10 described above.
