Description

Technical Field

[0001] The present application relates to the technical field of vehicle body structures, and in particular to a vehicle body assembly and a vehicle. Background Art

[0002] Nowadays, more and more hybrid extended-range models place the fuel tank between the battery pack and the rear subframe. This arrangement makes good use of the space in the length direction of the vehicle body. However, since the rear subframe is very close to the rear end of the fuel tank, in scenarios such as high-speed rear-end collisions, the front mounting point of the rear subframe is easily cut off, causing the rear subframe to move forward as a whole, causing the front end of the rear subframe to squeeze against the rear end of the fuel tank, which may cause the fuel tank to leak and explode.

DETAILED DESCRIPTION

[0023] The present application provides a vehicle body assembly and a vehicle, which can prevent the rear subframe 30 from squeezing the vehicle's power structure under impact. The vehicle body assembly and the vehicle are described in detail below with reference to the accompanying drawings. The features of the following embodiments and implementations can be combined with each other without conflict.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 The embodiment of the present application provides a vehicle body assembly, which includes a vehicle body 10, a blocking structure 20 and a rear subframe 30. The vehicle body 10 has a rear subframe front mounting position 11 and a power structure rear mounting position. In the length direction of the vehicle body 10, the rear subframe front mounting position 11 is arranged at the rear side of the power structure rear mounting position. The rear subframe 30 is fixedly connected to the vehicle body 10 via the rear subframe front mounting position 11, and the blocking structure 20 is fixedly connected to the vehicle body 10. The blocking structure 20 extends along the height direction of the vehicle body 10 and is located between the rear subframe front mounting position 11 and the power structure rear mounting position.

[0025] It can be seen from the above description that the blocking structure 20 is located between the front mounting position 11 of the rear sub-frame and the rear mounting position of the power structure, and extends along the height direction of the vehicle body 10. In this way, the blocking structure 20 can effectively separate the rear sub-frame 30 and the power structure. When the rear sub-frame 30 is subjected to an impact force from the rear to the front, the blocking structure 20 is fixed to the vehicle body, and the blocking structure 20 can be like a solid "wall", bearing the impact force transmitted from the rear sub-frame 30, blocking the rear sub-frame 30 from moving forward, thereby preventing the front end surface of the rear sub-frame 30 from squeezing the power structure located in front of the blocking structure 20. In other words, the blocking structure 20 provided in this solution can effectively bear the impact force transmitted from the rear sub-frame 30, and through its own strength and fixed connection with the vehicle body 10, the rear sub-frame 30 is restricted within the space between the blocking structure 20 and the front mounting position 11 of the rear sub-frame, thereby preventing the rear sub-frame 30 from squeezing and damaging the power structure in front of it.

[0026] It should be noted that the length direction of the vehicle body 10 is consistent with the front-rear direction. Figure 1 The front and rear directions shown, the height direction can refer to Figure 3 In addition, the power structure may include but is not limited to a fuel tank, a battery pack and an electric drive structure.

[0027] In one embodiment, the blocking structure 20 is formed on the vehicle body 10 and is integrally formed with the vehicle body 10 (not shown). With such a configuration, it is possible to avoid weak points or cracks at the connection between the blocking structure 20 and the vehicle body 10, thereby improving the stability of the blocking structure 20 and enhancing the blocking effect on the rear subframe 30. In addition, the integrally formed design simplifies the production process, and the blocking structure 20 does not need to be assembled with the vehicle body, thereby reducing the number of parts and assembly time during the vehicle assembly process. In another embodiment, please refer to Figure 2 and Figure 3 The blocking structure 20 has a mounting hole 22 for the second connecting member 52 to pass through, and the blocking structure 20 is fixedly connected to the vehicle body 10 through the second connecting member 52. The second connecting member 52 can be a threaded connecting member such as a bolt, a screw, a stud, etc., and the mounting hole 22 can be a threaded hole, but is not limited thereto.

[0028] In one embodiment, the rear sub-frame 30 includes a rear sub-frame front mounting portion 31, which is fixedly connected to the rear sub-frame front mounting position 11, and the blocking structure 20 has a blocking surface 21 facing the rear sub-frame 30, and the blocking surface 21 is configured to fit with the front end surface of the rear sub-frame front mounting portion 31. In this way, when the blocking structure 20 blocks the rear sub-frame front mounting portion 31, the blocking surface 21 can fit with the front end surface of the rear sub-frame front mounting portion 31, which makes the blocking structure 20 have a larger contact area with the rear sub-frame front mounting portion 31, which can more effectively disperse the impact force and pressure, and thus better block the rear sub-frame 30 from moving forward.

[0029] It should be noted that the adaptation here means that the blocking surface 21 and the front end surface of the rear sub-frame front mounting part 31 are consistent in shape, and the two can fit together. For example, the blocking surface 21 is a plane figure, and the front end surface of the rear sub-frame front mounting part 31 is also a plane figure. Alternatively, the blocking surface 21 is an uneven curved surface, and the front end surface of the rear sub-frame front mounting part 31 is also an uneven curved surface, and the concave portion of the blocking surface 21 corresponds to the convex portion of the front end surface of the rear sub-frame front mounting part 31, so that the concave portion of the blocking surface 21 can fit with the convex portion of the front end surface of the rear sub-frame front mounting part 31; the convex portion of the blocking surface 21 corresponds to the concave portion of the front end surface of the rear sub-frame front mounting part 31, so that the convex portion of the blocking surface 21 can fit with the concave portion of the front end surface of the rear sub-frame front mounting part 31. But it is not limited to this. In addition, the rear sub-frame 30 may include at least two rear sub-frame front mounting portions 31, and the number of the blocking structure 20 and the rear sub-frame front mounting positions 11 corresponds to the number of the rear sub-frame front mounting portions 31, but the present invention is not limited thereto. For example, in another embodiment, a plurality of rear sub-frame front mounting portions 31 may be provided, but only one blocking structure 20 may be provided.

[0030] like Figures 1 to 3 In the illustrated embodiment, the front mounting portion 31 of the rear sub-frame is in the shape of a hollow cylinder, so as to be mounted on the front mounting position 11 of the rear sub-frame of the vehicle body 10 through the first connecting member 51. The front end face of the front mounting portion 31 of the rear sub-frame is a cylindrical arc-shaped side surface, and the blocking surface 21 is set as an arc-shaped curved surface matching the cylindrical arc-shaped side surface. In other words, the front end face of the front mounting portion 31 of the rear sub-frame and the blocking surface 21 are both arc-shaped curved surfaces. The cylindrical design enables the first connecting member 51 to apply pressure uniformly along the circumference of the front mounting portion 31 of the rear sub-frame when tightened, thereby ensuring that the connection between the front mounting portion 31 of the rear sub-frame and the vehicle body 10 is tight and reliable. Moreover, compared with a plane figure, the design of the blocking surface 21 as an arc-shaped curved surface can provide a larger blocking area while occupying less space, thereby providing a better blocking effect. The blocking structure 20 may be a block-shaped, column-shaped or other structure, the first connector 51 may be a threaded connector such as a bolt, a screw, or a stud, and the rear subframe front mounting position 11 may be provided with a matching threaded hole, but is not limited thereto.

[0031] In one embodiment, the distance between the blocking surface 21 and the front end surface of the rear sub-frame front mounting portion 31 is 0 to 15 mm. That is, when the distance between the blocking surface 21 and the front end surface of the rear sub-frame front mounting portion 31 is 0, the blocking surface 21 of the blocking structure 20 fits the front end surface of the rear sub-frame front mounting portion 31. When the distance between the blocking surface 21 and the front end surface of the rear sub-frame front mounting portion 31 is greater than 0 and less than or equal to 15 mm, there is a small gap between the blocking structure 20 and the rear sub-frame front mounting portion 31. By controlling the distance between the blocking surface 21 and the front end surface of the rear sub-frame front mounting portion 31 to be between 0 and 15 mm, on the one hand, the blocking structure 20 can play a blocking role faster when the rear sub-frame 30 moves forward, and on the other hand, it helps to move the rear mounting position of the power structure backward, so that the power structure such as the battery pack and the fuel tank has a larger installation space, thereby increasing the volume of the power structure to improve the endurance of the whole vehicle.

[0032] Exemplarily, the distance between the blocking surface 21 and the front end surface of the rear sub-frame front mounting portion 31 may be 1 mm, 2 mm, 4 mm, 7 mm, 9 mm, 11 mm, 13 mm, or 15 mm.

[0033] In one embodiment, in the height direction of the vehicle body 10, the ratio of the height of the blocking structure 20 to the height of the front mounting portion 31 of the rear subframe is 1 / 3 to 1. It is easy to understand that when the height of the blocking structure 20 is higher, the bending resistance of the blocking structure 20 is weaker, and it is easier to bend under the impact force, resulting in failure. When the height of the blocking structure 20 is very low, the front mounting portion 31 of the rear subframe is easy to run over the blocking structure 20 when moving forward, and the blocking structure 20 is also easy to fail. Therefore, the solution provided in this embodiment can make the blocking structure 20 not easy to bend, and not easy to be run over, and can play a more stable blocking role. Exemplarily, the ratio of the height of the blocking structure 20 to the height of the front mounting portion 31 of the rear subframe can be 1 / 3, 1 / 2, 2 / 3, 1, etc. But it is not limited to this.

[0034] In one embodiment, the vehicle body assembly further includes an anti-fall structure 40, which is fixedly connected to the vehicle body 10 and located below the front mounting position 11 of the rear sub-frame, and is used to support the bottom of the front mounting portion 31 of the rear sub-frame. It is understandable that when the connection between the front mounting portion 31 of the rear sub-frame and the vehicle body 10 fails due to the impact force, the rear sub-frame 30 has a tendency to fall downward under the influence of its own gravity, and there is a risk of bypassing the blocking structure 20 and then squeezing the power structure. The anti-fall structure 40 is arranged below the rear sub-frame 30, and can support the rear sub-frame 30 to prevent the rear sub-frame 30 from falling below the blocking structure 20, thereby minimizing the rear sub-frame 30 from bypassing the blocking structure 20 and squeezing the power structure.

[0035] It can be known from the above description that when the rear sub-frame 30 is subjected to the impact force from the rear to the front, after the front mounting portion 31 of the rear sub-frame is disconnected from the vehicle body 10, the rear sub-frame 30 has a tendency to move forward and downward under the action of its own gravity and external impact force. The anti-fall structure 40 provided in this embodiment can support the rear sub-frame 30 and prevent the rear sub-frame 30 from falling downward. At the same time, the blocking structure 20 is located between the front mounting position 11 of the rear sub-frame and the rear mounting position of the power structure. The blocking structure 20 is like a solid barrier, which can prevent the rear sub-frame 30 from moving forward, thereby preventing the rear sub-frame 30 from moving forward and squeezing the power structure.

[0036] In summary, the blocking structure 20 and the anti-falling structure 40 complement each other. The blocking structure 20 is in the horizontal direction ( Figure 3 The blocking surface of the front and rear directions as shown in the figure is used to ensure the safety of the power structure, while the anti-falling structure 40 is used from the vertical direction ( Figure 3 The supporting layer of the rear subframe 30 (in the Z direction as shown) is used to prevent the rear subframe 30 from threatening the power structure due to an accidental fall. The blocking structure 20 and the anti-fall structure 40 together build a more comprehensive and reliable power structure rear side protection system for the power structure of the vehicle, thereby improving the safety and reliability of the power structure in the face of complex environments.

[0037] The connection between the anti-fall structure 40 and the vehicle body 10 may be direct or indirect.

[0038] In one embodiment, the anti-fall structure 40 also extends along the length direction of the vehicle body 10, and is fixedly connected to the blocking structure 20 and the front mounting portion 31 of the rear sub-frame, respectively. In other words, the anti-fall structure 40 is indirectly fixed to the vehicle body 10 through the blocking structure 20, and supports the front mounting portion 31 of the rear sub-frame by being fixedly connected to the front mounting portion 31 of the rear sub-frame. In this way, the anti-fall structure 40 utilizes the height of the blocking structure 20, so that the anti-fall structure 40 can be fixedly connected to the vehicle body 10 and can also be fixedly connected to the front mounting portion 31 of the rear sub-frame at the bottom of the front mounting portion 31 of the rear sub-frame. Moreover, this is also conducive to the connection stability of the anti-fall structure 40. In some other embodiments, the anti-fall structure 40 can be directly connected to the vehicle body 10, and can be fixedly connected to the structure of the rear sub-frame 30 other than the front mounting portion 31 of the rear sub-frame. For example, the anti-fall structure 40 can be fixedly set at the bottom of the front crossbeam of the rear sub-frame 30.

[0039] In one embodiment, the anti-fall structure 40 includes a first part 41 and a second part 42, wherein the first part 41 is adapted to the size of the front mounting portion 31 of the rear sub-frame and is fixedly connected to the front mounting portion 31 of the rear sub-frame, and the second part 42 is adapted to the size of the blocking structure 20 and is fixedly connected to the blocking structure 20, and there is a smooth transition between the first part 41 and the second part 42. By setting the first part 41 to be adapted to the size of the front mounting portion 31 of the rear sub-frame and the second part 42 to be adapted to the size of the blocking structure 20, the material of the anti-fall structure 40 can be saved, which is conducive to cost saving and lightweight design of the whole vehicle. The smooth transition between the first part 41 and the second part 42 can reduce the sharp design of the blocking structure 20 and avoid local stress concentration of the anti-fall structure 40.

[0040] In a specific embodiment, the anti-fall structure 40 is a plate-like structure, the first part 41 and the second part 42 are both circular in design, and the first part 41 and the second part 42 are connected by an arc transition. The first part 41 and the front mounting portion 31 of the rear subframe are fixed to the front mounting position 11 of the rear subframe of the vehicle body 10 through a first connecting member 51. The second part 42 and the blocking structure 20 are fixed to the vehicle body 10 through a second connecting member 52. After such arrangement, while reducing the number of connecting members, the first part 41 of the anti-fall structure 40 can also act as a gasket to make the connection between the front mounting portion 31 of the rear subframe and the vehicle body 10 more secure. Similarly, the second part 42 of the anti-fall structure 40 can also act as a gasket to make the connection between the blocking structure 20 and the vehicle body 10 more secure. The first connecting member 51 and the second connecting member 52 can both be, but are not limited to, bolts, studs, and screws.

[0041] An embodiment of the present application also provides a vehicle, which includes the body assembly described in any of the above embodiments or implementations.

[0042] In one embodiment, when the vehicle is a hybrid vehicle, the vehicle body 10 is further provided with a front mounting position of a power structure, and the power structure of the vehicle includes a battery pack and a fuel tank, the battery pack is installed at the front mounting position of the power structure, the fuel tank is installed at the rear mounting position of the power structure, the fuel tank is located between the battery pack and the rear subframe 30, and the blocking structure 20 is located between the fuel tank and the front mounting position 11 of the rear subframe. In this embodiment, the blocking structure 20 can block the rear subframe 30 from moving forward to prevent the rear subframe 30 from squeezing the rear end face of the fuel tank. In this way, after avoiding the risk of the rear subframe 30 squeezing the fuel tank, the fuel tank provided in this embodiment can be arranged as close to the rear subframe 30 as possible to increase the volume of the fuel tank, thereby improving the endurance of the vehicle. However, it is not limited to this. For example, in another embodiment, the battery pack can be installed at the rear mounting position of the power structure, the fuel tank can be installed at the front mounting position of the power structure, and the blocking structure 20 is located between the rear end face of the battery pack and the front mounting position 11 of the rear subframe.

[0043] In another embodiment, when the vehicle is an electric vehicle, the power structure of the vehicle includes a battery pack, which is installed at the rear mounting position of the power structure. The blocking structure 20 is located between the battery pack and the front mounting position 11 of the rear subframe. The blocking structure can prevent the rear subframe 30 from squeezing the rear end surface of the battery pack.

[0044] Furthermore, the power structure of the vehicle may also include an electric drive structure, and the vehicle body 10 may also include a front mounting position of the power structure, the electric drive structure is arranged at the front mounting position of the power structure, and is connected to the battery pack to drive the front wheels of the vehicle to rotate. Of course, in some other embodiments, the electric drive structure may be installed at the rear mounting position of the power structure, the battery pack may be installed at the front mounting position of the power structure, and the blocking structure 20 may be located between the electric drive structure and the front mounting position 11 of the rear subframe.

[0045] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
