[0040] like Figure 1-Figure 8 As shown, a vehicle body structure 100 according to an embodiment of the present invention comprises: a first sill beam 1 , a second sill beam 2 and a mounting longitudinal beam 3 .

[0042] Specifically, the vehicle body structure 100 is provided with a first sill beam 1 and a second sill beam 2, and the first sill beam 1 and the second sill beam 2 are both extended in the front-rear direction of the vehicle, and the first sill beam 1 and the second sill beam 2 are arranged at intervals along the lateral direction of the vehicle and are arranged on both sides of the vehicle body. The sill beams are used to connect the front of the door and the A-pillar and the rear of the door and the B-pillar, and the sill beams are usually located at the bottom of the door and can be used to separate the area inside and outside the vehicle. The sill beams have high rigidity. When the two sides of the vehicle are subjected to collision force, the collision force can act on the sill beams, thereby improving the safety of the vehicle. In actual setting, the first sill beam 1 can be set on the left side of the vehicle and the second sill beam 2 can be set on the right side of the vehicle, or the first sill beam 1 can be set on the right side of the vehicle and the second sill beam 2 can be set on the left side of the vehicle, thereby improving the flexibility of setting.

[0043] Furthermore, the vehicle body structure 100 is also provided with an installation longitudinal beam 3, and the installation longitudinal beam 3 can be connected to the vehicle floor 5 by welding or a connecting piece 6, and the installation longitudinal beam 3 is also extended along the front and rear direction of the vehicle, that is, the installation longitudinal beam 3 can be arranged in parallel with the first sill beam 1 and the second sill beam 2, and the installation longitudinal beam 3 is arranged between the first sill beam 1 and the second sill beam 2, so that the installation longitudinal beam 3 can jointly define a first installation space 31 with the first sill beam 1, and the first installation space 31 can be used to accommodate the battery pack 101, that is, the battery pack 101 can be arranged in the first installation space 31, and the two sides of the battery pack 101 can be respectively connected to the installation longitudinal beam 3 and the first sill beam 1 by welding or a connecting piece 6, etc.

[0044] In actual settings, when the first sill beam 1 is set on the left side of the vehicle, the first installation space 31 is formed on the left side of the vehicle, and the battery pack 101 can be installed on the left side of the vehicle. When the first sill beam 1 is set on the right side of the vehicle, the first installation space 31 is formed on the right side of the vehicle, and the battery pack 101 can be installed on the right side of the vehicle, thereby improving setting flexibility.

[0045] By only installing one longitudinal beam 3 in conjunction with the first sill beam 1 and the second sill beam 2, the number of longitudinal beams 3 can be reduced, thereby increasing the weight of the vehicle, thereby increasing vehicle endurance performance, and improving user experience. The first sill beam 1 and the second sill beam 2 have high rigidity, and the battery pack 101 is installed in the first installation space 31, thereby ensuring the installation reliability of the battery pack 101 and improving the torsional stiffness of the entire vehicle, thereby ensuring vehicle handling performance, improving safety in use, and ensuring user comfort.

[0046] According to the vehicle body structure 100 of the embodiment of the present invention, a mounting longitudinal beam 3 is matched with the first sill beam 1 to define a first mounting space 31 for accommodating the battery pack 101, thereby reducing the number of mounting longitudinal beams 3 and improving the lightweight of the vehicle to ensure the vehicle's endurance performance. The first sill beam 1 has a high rigidity, which can ensure the torsional stiffness of the entire vehicle, thereby ensuring the vehicle's handling performance, thereby improving safety in use, ensuring comfort in use, achieving better use effects, and having a wider range of applications.

[0047] In some embodiments, the mounting longitudinal beam 3 is spaced apart from the second rocker beam 2 , and a second mounting space 32 for avoiding the pipeline 102 of the exhaust system is defined between the mounting longitudinal beam 3 and the second rocker beam 2 .

[0048] Specifically, the mounting longitudinal beam 3 is arranged between the first threshold beam 1 and the second threshold beam 2, and Figure 3 As shown, the installation longitudinal beam 3 is spaced apart from the first threshold beam 1 and the second threshold beam 2, respectively, so that the installation longitudinal beam 3 can define a first installation space 31 with the first threshold beam 1, and can define a second installation space 32 with the second threshold beam 2. The first installation space 31 can be used to install the battery pack 101, and the second installation space 32 can be used to avoid the pipe 102 of the exhaust system, so that the battery pack 101 and the pipe 102 of the exhaust system can be separated and arranged, so as to avoid the heat generated by the pipe 102 of the exhaust system affecting the operating reliability of the battery pack 101 and extend the service life of the battery pack 101.

[0049] Furthermore, the width of the exhaust system pipe 102 is smaller than the width of the battery pack 101, so that in actual setting, the size of the first installation space 31 in the lateral direction of the vehicle is set to be larger than the size of the second installation space 32 in the lateral direction of the vehicle, that is, the installation longitudinal beam 3 is arranged close to the second sill beam 2, thereby ensuring the installation reliability of the battery pack 101. In some embodiments, the vehicle body structure 100 further includes a connecting plate 4, one end of which is connected to the second sill beam 2, and the other end of the connecting plate 4 is connected to the installation longitudinal beam 3 and / or the battery pack 101.

[0050] Specifically, the vehicle body structure 100 is further provided with a connecting plate 4, such as Figure 1-Figure 7As shown, the connecting plate 4 can be provided in plurality, and the plurality of connecting plates 4 can be spaced apart along the front-rear direction of the vehicle, the connecting plate 4 can be provided with steel or aluminum, etc., and the connecting plate 4 is provided corresponding to the second installation space 32, the second sill beam 2 and the installation longitudinal beam 3 jointly define the second installation space 32, one side of the connecting plate 4 can be connected to the second sill beam 2 through a connecting member 6, and the other end of the connecting plate 4 can be connected to the installation longitudinal beam 3 and / or the battery pack 101 through a connecting member 6, that is, the other end of the connecting plate 4 can be connected only to the installation longitudinal beam 3 through the connecting member 6, or can be connected only to the battery pack 101 through the connecting member 6, or can be connected to both the installation longitudinal beam 3 and the battery pack 101 through the connecting member 6.

[0051] Furthermore, in the present embodiment, one end of the connecting plate 4 is connected to the second threshold beam 2 via a connecting member 6, and the other end is connected to the mounting longitudinal beam 3 via a connecting member 6. The connecting member 6 can be set as a bolt or the like, which has a simple structure, is easy to install, and has a low installation cost. The connecting plate 4 is connected between the second threshold beam 2 and the mounting longitudinal beam 3, so that when the outer side of the second threshold beam 2 is subjected to a collision force, the collision force can be transmitted inward along the connecting plate 4, thereby weakening the effect of the collision force. In addition, the connecting plate 4 is set between the second threshold beam 2 and the mounting longitudinal beam 3, which can support the second threshold beam 2 and the mounting longitudinal beam 3 in the lateral direction, so that during a collision of the side of the vehicle, the intrusion of the side can be effectively reduced, thereby ensuring that the battery pack 101 and the exhaust system pipeline 102 are not squeezed, thereby improving the safety of use, and at the same time improving the overall torsional stiffness of the vehicle, thereby ensuring the vehicle handling performance and improving the user experience.

[0052] In some embodiments, the connection plate 4 is located below the second installation space 32 , and the connection plate 4 is used to support the pipe 102 of the exhaust system.

[0053] Specifically, Figure 1-Figure 4 As shown, one side of the connecting plate 4 is connected to the second threshold beam 2, and the other side is connected to the mounting longitudinal beam 3, thereby supporting the second threshold beam 2 and the mounting longitudinal beam 3 in the lateral direction, reducing the intrusion amount of the side, and as shown in FIG. Figure 4 As shown, the connecting plate 4 is located below the second installation space 32, that is, one side of the connecting plate 4 is connected to the lower end surface of the second sill beam 2 through a connecting piece 6, and the other side of the connecting plate 4 is connected to the side surface of the battery pack 101 through a connecting piece 6, and in actual setting, the other side of the connecting plate 4 can also be connected to the lower end surface of the mounting longitudinal beam 3 through a connecting piece 6, so that the second sill beam 2, the connecting plate 4, the mounting longitudinal beam 3 and the vehicle floor 5 jointly define the second installation space 32.

[0054] Furthermore, if Figure 2As shown, the pipe 102 of the exhaust system is accommodated in the second installation space 32, and the connecting plate 4 is located below the second installation space 32, that is, the connecting plate 4 is arranged below the pipe 102 of the exhaust system. When the pipe 102 of the exhaust system is installed in the second installation space 32, the connecting plate 4 can support the pipe 102 of the exhaust system to provide an upward supporting force to the pipe 102 of the exhaust system, thereby ensuring the reliability of the installation of the pipe 102 of the exhaust system.

[0055] In some embodiments, the connecting plate 4 is constructed as a stamped plate, and an arched reinforcement area 41 is formed in the middle of the stamped plate.

The stamped plate is located below the second installation space 32, and the arched reinforcement area 41 protrudes toward the side away from the second installation space 32. The stamped plate can provide an upward supporting force to the pipe 102 of the exhaust system, and the pipe 102 of the exhaust system can be partially placed in the arched reinforcement area 41 to limit the pipe 102 of the exhaust system to avoid the pipe 102 of the exhaust system from shaking left and right when the vehicle is running, thereby improving the NVH performance of the vehicle and ensuring riding comfort.

[0057] In other embodiments, the connecting plate 4 is constructed as an extruded plate, and a first reinforcement cavity 42 is formed in the extruded plate.

[0058] Specifically, the connecting plate 4 can also be constructed as an extruded plate, which can be set to aluminum material, thereby improving the weight, avoiding oxidation of the extruded plate, and extending the service life of the extruded plate.

[0073] In some embodiments, at least two second reinforcement cavities 21 are formed in the first sill beam 1 and / or the second sill beam 2 .

[0074] Specifically, the vehicle body structure 100 is provided with a first sill beam 1 and a second sill beam 2 extending in the front and rear directions, and the first sill beam 1 and the second sill beam 2 are arranged spaced apart in the left and right directions, and as shown in FIG. Figure 1 as well as Figure 3-Figure 5 As shown, at least two second reinforcement cavities 21 are formed in the first sill beam 1 and / or the second sill beam 2, that is, at least two second reinforcement cavities 21 are formed only in the first sill beam 1, at least two second reinforcement cavities 21 are formed only in the second sill beam 2, or at least two second reinforcement cavities 21 are formed in both the first sill beam 1 and the second sill beam 2. In the present embodiment, at least two second reinforcement cavities 21 are formed in both the first sill beam 1 and the second sill beam 2.

[0075] Furthermore, at least two second reinforcement cavities 21 are formed in the first sill beam 1 and the second sill beam 2, that is, two, three or four second reinforcement cavities 21 can be formed in the first sill beam 1 and the second sill beam 2, and the multiple second reinforcement cavities 21 arranged in the first sill beam 1 and the second sill beam 2 can be distributed in the horizontal and vertical directions. After the collision force acts on the outer wall of the first sill beam 1 or the outer wall of the second sill beam 2, it can be transmitted inward and then weakened by the multiple second reinforcement cavities 21, so as to reduce the collision force transmitted to the exhaust system pipeline 102 and the battery pack 101, thereby improving the safety of use. Moreover, at least two second reinforcement cavities 21 are formed in the first sill beam 1 and the second sill beam 2, which can improve the torsional stiffness of the whole vehicle, thereby improving the comfort and handling of the whole vehicle.
