The vehicle body structure and the vehicle provided in the embodiments of the present application are described in detail below with reference to fig. 1 to 6.

According to one embodiment of the application, a vehicle body structure is provided, which can be suitably applied to electric vehicles, such as electric sports cars and the like, and can realize the light weight and collision resistance requirements of pure electric high-endurance vehicles.

An embodiment of the present application provides a vehicle body structure, referring to fig. 1 to 4, including: a central tunnel 213, a dash panel 201 and a rear floor cross member 215; wherein the central passage 213 extends in the vehicle front-rear direction; the dash panel 201 and the rear floor cross member 215 are disposed at an interval in the vehicle front-rear direction; the central passage 213 is connected at a first end to the dash panel 201 and at a second end to the rear floor cross member 215.

According to the vehicle body structure provided in the foregoing embodiment of the present application, the central passage 213 is disposed in the middle of the vehicle body structure in a penetrating manner along the front-rear direction of the vehicle body, and forms a force transmission structure.

Referring to fig. 1 to 6, the X direction shown in the drawings refers to the front-rear direction of the vehicle, the Y direction refers to the width direction of the vehicle, and the Z direction refers to the height direction of the vehicle.

Specifically, referring to fig. 1 to 4, a first end, i.e., a front end, of the center tunnel 213 is supported by the dash panel 201 provided at the front portion of the vehicle body, and a second end, i.e., a rear end, of the center tunnel 213 is supported by the rear floor cross member 215 provided at the rear portion of the vehicle body. And, the central passage 213 is connected to the floor 211 to form a force transmitting cavity, which allows the formed force transmitting structure to extend from the dash panel 201 at the front of the vehicle body to the rear floor cross member 215 at the rear of the vehicle body, thus forming a continuous force transmitting passage from front to rear. In this way, when the vehicle front portion is involved in a collision, the collision force can be directly transmitted from the vehicle front portion to the vehicle rear portion.

The central channel 213 provided in this embodiment of the present application, as a force transmission channel of a vehicle, can make a force transmission path more complete, and form a continuous force transmission path in the middle of a cabin of the vehicle, so as to play a role in force transmission, energy absorption and load dispersion.

According to the vehicle body structure provided by the embodiment of the application, the transmission structure, namely the central channel 213 is subjected to new structural design, so that force can be transmitted from the front coaming to the rear floor beam 215 through the central channel 213, a continuous transmission channel is provided, collision force can be directly transmitted from the front part of the vehicle to the rear part, namely after the vehicle is collided, the transmission path of the force is more complete, and the safety of the vehicle can be improved.

In some examples of the present application, referring to fig. 1 to 3, the dash panel 201 is provided on the front side of the rear floor cross member 215 in the vehicle front-rear direction; the height of the central passage 213 gradually decreases from the dash panel 201 to the rear floor cross member 215; the height of the central passage 213 is the height of the surface of the floor 211 protruding from the vehicle.

That is, the central passage 213 is entirely raised above the surface of the floor 211 of the vehicle.

In the vehicle body structure provided in the above embodiment of the present application, the cross section of the central passage 213 forms a gradually decreasing trend from the first end to the second end. Referring to fig. 4, it can also be understood that the cross section of the central channel 213 has a low-transition tendency with a high front and a low rear in the X direction. Wherein the X direction refers to the front-rear direction of the vehicle.

In particular, in order to increase the cross-sectional force of the central passage 213 as much as possible based on the force transmission requirements for vehicle collision and the seat height limitation, the cross-section of the central passage 213 is designed to exhibit a slow transition trend in the X-direction. Referring to fig. 2, in the crash condition, the crash force is transferred to the dash panel 201 via the front side member of the vehicle and then transferred to the central channel 213, and the force transferred by the central channel 213 is gradually reduced in the forward direction along the X direction, so that the required section force can be gradually reduced.

According to the vehicle body structure provided by the embodiment of the application, a new structural design is performed on a force transmission structure, namely the central channel 213, the section of the central channel 213 shows a slow transition trend of being high at the front and low at the rear from the first end (front end) to the second end (rear end), and the lightweight design of the central channel 213 can be realized. The central passage 213 extends from the dash panel 201 at the front of the vehicle body to the rear floor cross member 215 so that the force transmission path is more complete.

In the above example of the present application, the height of the central passage 213 is designed to be gradually reduced in order to enable a gradual transfer of force to the lower body, which is the force transfer structure of the vehicle, thus enabling a better force transfer.

In some examples of the present application, the body structure further includes a first cross member 207, the first cross member 207 being connected to the central channel 213.

According to the above example, the force can be better transmitted to the central passage 213.

Wherein a projection of the first end (i.e., front end) of the center tunnel 213 in the vehicle front-rear direction at least partially overlaps with a projection of the first cross member 207 in the vehicle front-rear direction. The force transmission path may extend from the first cross member 207 all the way to the rear floor cross member 215.

In some examples of the present application, the vehicle body structure further includes a first cross member 207, the first cross member 207 is connected to the dash panel 201, and the first cross member 207 is disposed on a side of the dash panel 201 remote from the central tunnel 213.

It should be noted that the first cross member 207 mentioned in the above two examples is, for example, a single member, which may be enclosed with the dash panel 201 located in front of the vehicle body to form a hollow structure. The first beam 207 is generally disposed on a side remote from the central passage 213.

The first cross member 207 may be another type of beam having a cavity defined by, for example, a floor 211 and a dash panel 201 of the vehicle, as will be described later.

In some examples of the present application, referring to fig. 1 to 3, the vehicle body structure further includes a seat front cross member 214, the seat front cross member 214 extending in the vehicle width direction; the dash panel 201, the seat front cross member 214, and the rear floor cross member 215 are sequentially arranged at intervals in the front-rear direction of the vehicle, and the seat front cross member 214 is connected to the central passage 213; wherein the seat front cross member 214 transversely extends through the central passage 213, and the central passage 213 straddles the seat front cross member 214.

In the vehicle body structure provided in the above embodiment of the present application, the middle portion of the central passage 213 forms an overlap joint with the seat front cross member 214, and at this time, the seat front cross member 214 can also support the central passage 213, so that the structural rigidity of the central passage 213 can be increased.

Specifically, referring to fig. 3 and 4, when the vehicle collides in a forward direction, the force from the central passage 213 is transferred to the seat front cross member 214, and the force starts to be dispersed to both sides to the vehicle rocker position, so that the situation that the local position of the floor 211 of the vehicle is excessively stressed to press the battery pack downward is avoided. Since the central passage 213 is connected to the middle position of the seat front cross member 214, deformation instability of the seat front cross member 214 can be reduced at the time of a side column collision.

Referring to fig. 1 to 3, the central tunnel 213 connects the seat front cross member 214 and the rear floor cross member 215 in the longitudinal direction (X direction) of the vehicle body; the seat front cross member 214 transversely penetrates through the middle of the central passage 213, and the central passage 213 straddles the seat front cross member 214, so that the seat front cross member 214 and the central passage 213 form a cross-shaped reinforcing structure.

Specifically, referring to fig. 3, the front seat beam 214 is transversely inserted and embedded in the central channel 213, that is, the central channel 213 presses the front seat beam 214 right under, so as to form a cross structure, which is a reinforcing structure, and can improve the structural strength against collision.

The structural design adopted in the above example ensures the smoothness of the structure, and enables the whole structure to obtain good strength and rigidity in the longitudinal direction and the transverse direction. The torsional rigidity performance of the whole cabin is improved to a certain extent, and the driving comfort and safety are improved.

The front cross beam 207 and the forces transmitted from the side surfaces of the front cross beam can be effectively dispersed to the floor 211, the seat front cross beam 214, the rear floor cross beam 215 and other load bearing structures of the vehicle body in the front collision and side collision processes, and the situation of overturning and unstability of the front part of the vehicle in the front collision is restrained to the greatest extent, so that the force transmission is more reasonable.

In some examples of the present application, referring to fig. 3, two ends of the front seat cross member 214 are respectively connected to a vehicle threshold beam; the seat front cross member 214 has a cavity filled with seat front cross member reinforcing foam 216.

For the above example, the cavity of the seat front beam 214 may be formed by the seat front beam itself or may be formed by surrounding the floor 211, which is not limited in this application.

The seat front cross member 214 is connected at both ends to vehicle rocker beams on both left and right sides of the vehicle body structure, respectively. Referring to fig. 3, the seat front cross member 214 has a cavity filled with seat front cross member reinforcing foam 216.

The seat front cross member 214 is, for example, a laterally penetrating integral beam structure that is connected between the left and right vehicle threshold beams. In the collision condition, the collision force is transferred to the central channel 213 via the first beam 207, and when transferred to the position of the seat front beam 214, the collision force starts to be dispersed to the side sill beams to the two sides, so that the collision force can be dispersed.

The seat front rail 214 has a cavity, for example, and in order to increase the strength and rigidity of the seat front rail 214 upon impact with a side pillar, and to reduce deformation instability, it is optional to fill the cavity of the seat front rail 214 with a foam material, namely the seat front rail reinforcing foam 216 mentioned in the above example.

The seat front cross member 214 is filled with foam material to increase the rigidity of the front cavity and to facilitate the transfer of crash forces rearward along the central passage 213. The rear floor rail 215 forms a large cavity with the floor 211 that can receive some of the force from the central channel 213 while distributing the force along the seat front rail 214 to both sides of the rocker.

In addition, the seat front cross member reinforcement foam 216 may provide a seat front mounting point internally, for example, by pre-inserting nuts, and the connection structure may meet the seat front mounting strength requirement.

Alternatively, referring to fig. 3 and 5, the central channel 213 is a beam structure in a shape of a letter, a flange structure is provided on a peripheral side of the central channel 213, and the central channel 213 is adhered and fixed to the floor 211 by the flange structure on the peripheral side.

The lower peripheral side of the central passage 213 is provided with a burring structure, which forms a kind of a girder of a zigzag structure. The central channel 213 may be secured to the floor 211 by a flange structure. For example, the central passage 213 may be fixed to the floor 211 by using an adhesive in the above example.

In some examples of the present application, the vehicle body structure further includes a floor 211, and the floor 211 encloses a connecting portion with the dash panel 201 to form a cavity structure to form the first cross member 207.

As previously described, another form of the first cross member 207 is a beam having a cavity surrounded by the floor 211 and the dash panel 201.

Optionally, the first beam 207 is filled with a cavity reinforcement.

The vehicle body structure includes, for example, a dash panel 201 and a dash lower panel 202, and the floor panel 211 is connected to the dash panel 201 and the dash lower panel 202, respectively. Wherein the floor 211 and the connecting portion of the dash panel 201 are enclosed to form a cavity structure, which forms the above-mentioned first-size cross member 207, see fig. 2.

The cavity structure of the first beam 207 is filled with a cavity reinforcement, please continue to refer to fig. 2.

The cavity reinforcement is for example a foam material.

For example, the cavity of the first beam 207 is filled with a foam material (see fig. 3. The first beam 207 is filled with black). The foam material has the characteristics of light weight and good plastic deformation, and after being filled into the cavity of the first beam 207, the foam material forms a supporting effect on plates in all directions, so that the energy absorption effect of the overall structure is further enhanced.

In some examples of the present application, the vehicle body structure further includes a seat mounting structure, see fig. 3, 5 and 6, including a mounting bracket and a mounting block; wherein, the installation block is connected with the floor 211, the installation bracket is connected with the installation block, and in the height direction of the vehicle, a part of the installation bracket is arranged at intervals with the floor 211.

According to the above example of the present application, the mounting bracket is raised by a mounting block.

Wherein the mounting bracket is used for mounting the seat guide rail. And the seat is mounted on the seat rail.

Optionally, referring to fig. 3, 5 and 6, the mounting bracket includes an inner mounting bracket 232 disposed proximate the central channel 213 and an outer mounting bracket 231 disposed proximate the vehicle threshold beam; the mounting blocks comprise an outer mounting block 221, a middle mounting block 222 and an inner mounting block 223 which are connected with the floor; one side of the inner mounting bracket 232 is connected with the inner mounting block 223, and the other side is connected with the central channel 213; the outer mounting bracket 231 has one side connected to the middle mounting block 222 and the other side connected to the outer mounting block 221.

Wherein, the middle mounting block 222 and the inner mounting block 223 are both used for mounting and elevating the outer mounting bracket 231 and the inner mounting bracket 232. The outer mounting bracket 231 and the inner mounting bracket 232 are both mounting brackets for the seat rail. That is, the seat rail is mounted on the outer mounting bracket 231 and the inner mounting bracket 232.

Since the seat needs to be movable, in the vehicle body structure of the embodiment of the present application, the floor 211 is designed to be relatively low so as to be suitable for a sports car type, and a part of the mounting bracket such as the above-mentioned inner mounting bracket 232 is mounted on the central passage 213, it is necessary to introduce the middle mounting block 222 to support and fix the outer mounting bracket 231. The outer mounting block 221 is only on the vehicle rocker side, and is different from the middle mounting block 222 and the inner mounting block 223. In order to make the connection of the mounting blocks better, an outer mounting bracket 231 is added, and the middle mounting block 222 and the outer mounting bracket 231 are connected, and can be connected to the floor 211 and the vehicle threshold beam through the outer mounting block 221 to increase the connection firmness.

Optionally, the outer mounting bracket 231 and the inner mounting bracket 232 are respectively provided with a rear mounting point for fixing the seat rail; the seat front cross member 214 is provided with a front mounting point for fixing the seat rail. The outer mounting bracket 231 and the inner mounting bracket 232 are bracket shaped like a Chinese character 'ji'.

That is, the central channel 213 not only takes on a force transmission effect, but also a seat rail mounting point is integrated into the central channel 213.

When a collision occurs, the force transmitted by the front collision of the first cross beam 207 (containing foam) is transmitted to the central channel 213, and the central channel 213 is integrated with the floor 211, the seat front cross beam 214, the inner mounting bracket 232 and the rear floor cross beam 215, so that various force transmission can be transmitted in a dispersed manner, and the integral stress is improved by single parts, so that the invasion amount of the front surrounding plate 201 and the front surrounding lower plate 202 during the front collision is reduced, and the purpose of protecting personnel safety in a seat cabin is achieved.

The seat front beam 214 is, for example, of a shape like a Chinese character 'ji', and is overlapped with the floor 211 through a flanging on the peripheral side of the seat front beam 214, and a cavity between the seat front beam 214 and the floor 211 is filled with foam material to form a seat front beam reinforced foam 216, so that the rigidity of the cavity between the seat front beam 214 and the floor 211 is increased, and meanwhile, the dispersed transmission of collision force along the central channel 213 to the rear and the side is facilitated.

Specifically, referring to fig. 1, the floor 211 integrates the outer mounting block 221, the middle mounting block 222, and the inner mounting block 223 by way of inlaying. The outer mounting block 221, the middle mounting block 222, and the inner mounting block 223 may be configured to mount a single seat assembly. The seat assembly may be provided in two sets, and the outer mounting block 221, the middle mounting block 222, and the inner mounting block 223 are required to be provided in two sets, and are symmetrically arranged in a left-right direction, as can be seen in fig. 1.

Specifically, referring to fig. 5, the seat front cross member 214 is designed with 4 bolt holes H1, which are front mounting points for fixing the seat rail.

Further, the main structure of the bolt hole H1 is that a nut is embedded in the foam to provide a front mounting point of the seat rail, and the connecting structure can meet the strength requirements of the seat rail and the seat mounting, so that the safety performance of the whole structure is further improved after the seat rail and the seat mounting are completed.

Specifically, referring to fig. 6, a left and right side seat mounting structure is shown. In the left seat mounting structure, the outer mounting block 221 is provided with a bolt hole R1, the middle mounting block 222 is provided with a bolt hole R2, and the inner mounting block 223 is provided with a bolt hole R3. In the right seat mounting structure, the outer mounting block 221 is provided with a bolt hole L1, the middle mounting block 222 is provided with a bolt hole L2, and the inner mounting block 223 is provided with a bolt hole L3. Further, the central passage 213 is provided with R4 bolt holes and L4 bolt holes. These bolt holes are used for fixing the outer mounting bracket 231 and the inner mounting bracket 232 to the floor 211 and the central passage 213.

Referring to fig. 1, left and right inner mounting brackets 232 are mounted to cross the central passage 213 and the floor 211, and after each of the inner mounting brackets 232 is fastened to the central passage 213 and the floor 211 by bolts, the rigidity of the central passage 213 in the lateral and longitudinal directions is further enhanced.

Optionally, the dash panel 201, the floor 211, the central channel 213, the seat front cross member 214, and the rear floor cross member 215 are all carbon fiber reinforced polymer matrix composite materials.

The carbon fiber reinforced polymer matrix composite has enough strength and rigidity, is the lightest material for manufacturing main structural parts of automobile bodies, and is the highest technical level for realizing light weight of the whole automobile at present. The application of the carbon fiber composite material can reduce the weight of an automobile body by 40% -60%, which is equivalent to 1/3-1/6 of the mass of the steel structure.

Meanwhile, the energy absorption capacity of the carbon fiber reinforced composite material in collision is 4-5 times that of steel or aluminum, and the carbon fiber reinforced composite material has good collision safety when used for vehicle body structural parts.

Meanwhile, based on the light weight characteristic of the carbon fiber, the weight of the upper automobile body can be reduced, and the light weight design of the whole automobile is facilitated.

Also, in the vehicle body frame provided in the above embodiment, the lower vehicle body structure is specifically a metal frame. The metal frame is an aluminum frame, for example, so that the collision safety performance of the whole vehicle can be ensured.

The vehicle body structure provided by the embodiment of the application can be applied to pure electric high-endurance vehicles, in particular to electric sports car types. First, sports cars are required to have ultra-high performance, and vehicle body architectures are required to meet the requirements of higher performance and lighter weight, but existing vehicle body architectures are generally in a metal form, and it is difficult to meet the requirements of high performance of sports cars. Secondly, the requirements on the safety performance of the automobile are higher and higher, and particularly, the requirements on the national emerging star rating, middle insurance research test and other projects are basically unsatisfied by the conventional sports car type. These above all put more demands on the body architecture of a sports car.

The vehicle body structure provided by the embodiment of the application can meet the requirements on the sports car body framework, and can meet the safety requirements of automobiles while realizing the lightweight design of the vehicle body.

Optionally, at least part of the metal frame is made of metal aluminum.

That is, the vehicle body structure provided in the embodiment of the present application may include a carbon fiber cabin located at an upper portion and an aluminum frame located at a lower portion, which are connected to form a lap joint structure. For the car body frame, the metal frame can be made of aluminum integrally, so that the car body frame has the advantages of light weight, good corrosion resistance, good impact resistance, strong plasticity and the like, and the production cost is not excessively increased.
