[0032] It should be noted that in the related art, the battery device of the electric vehicle is usually located at the bottom of the vehicle, and when the vehicle is subjected to a circumferential impact, the battery device is prone to extrusion and deformation, which may cause short circuit of the battery and even fire, so the column impact test is of great significance in automobile safety test. Most of the existing vehicle rocker beams do not have sufficient strength and rigidity to resist impact, affecting the safety of the battery device.

[0033] Based on this, the embodiment of the present application provides a vehicle body assembly 1, the opposite sides of the floor body 10 are provided with a rocker beam 20 along the height direction of the vehicle body assembly 1, that is, the floor body 10 can be located between the two sides of the rocker beam 20 along the height direction of the vehicle body assembly 1. When the vehicle body assembly 1 is arranged in the Figure 1 direction, the height direction of the vehicle body assembly 1 is the Z direction in the Figure 1 , the height direction of the vehicle body assembly 1 can be parallel to the height direction of the vehicle. The rocker beam 20 can be formed with a first flange protruding towards the battery device along the width direction of the vehicle body assembly 1, the first flange can be integrally formed with the rocker beam 20, and the first flange can be a separate part from the rocker beam 20. When the vehicle body assembly 1 is arranged in the Figure 2 direction, the width direction of the vehicle body assembly 1 is the X direction in the Figure 2 , the width direction of the vehicle body assembly 1 can be parallel to the width direction of the vehicle. The first flange can be located on the side of the rocker beam 20 facing the battery device, the first flange can be located between the two sides of the rocker beam 20 along the height direction of the vehicle body assembly 1, the floor body 10 can be overlapped with the first flange, the floor body 10 can be welded to the first flange, and the floor body 10 can be fixedly connected to the rocker beam 20 through the first flange. The floor body 10 has a mounting longitudinal beam 11, which can be used to mount the battery device. The mounting longitudinal beam 11 and the rocker beam 20 can be oppositely arranged and spaced apart along the width direction of the vehicle body assembly 1, and a first collapse space can be formed between the mounting longitudinal beam 11 and the rocker beam 20. When the rocker beam 20 is impacted, the rocker beam 20 can deform and absorb energy towards the first collapse space.

[0034] The support beam 30 can be arranged between the rocker beam 20 and the corresponding mounting longitudinal beam 11. The rocker beam 20 can be fixedly connected with the support beam 30. As an example, the support beam 30 can be welded with the rocker beam 20. The support beam 30 can also be connected with the rocker beam 20 through a flow-drilling screw process. This is favorable to improve the connection strength of the support beam 30 and the rocker beam 20, and can improve the anti-impact capability of the rocker beam 20. The support beam 30 can be located in the first collapse space. The support beam 30 can be spaced apart from the corresponding mounting longitudinal beam 11. The support beam 30 can support the rocker beam 20. The support beam 30 can play a role in improving the strength and rigidity of the rocker beam 20. When the rocker beam 20 is impacted, the rocker beam 20 can deform and absorb energy towards the first collapse space. The support beam 30 can absorb and disperse the impact force, which can reduce the degree of indentation of the rocker beam 20. With the deformation of the rocker beam 20, the support beam 30 can be in contact with the mounting longitudinal beam 11. The support beam 30 can collapse and absorb energy. The rocker beam 20 can transmit force to the mounting longitudinal beam 11 through the support beam 30. This can reduce the impact force on the mounting longitudinal beam 11 and the probability of deformation of the mounting longitudinal beam 11, thereby being favorable to improve the reliability of the vehicle.

[0035] In the embodiments of the present application, the support beam 30 can support the rocker beam 20 and improve the rigidity and strength of the rocker beam 20. When the rocker beam 20 is impacted, the rocker beam 20 deforms and absorbs energy. The support beam 30 can absorb and disperse the impact force on the rocker beam 20, which can reduce the degree of indentation of the rocker beam 20. With the deformation of the rocker beam 20, when the support beam 30 is in contact with the mounting longitudinal beam 11, the support beam 30 can collapse and absorb energy, which can reduce the impact force transmitted by the rocker beam 20 to the mounting longitudinal beam 11 and reduce the deformation of the mounting longitudinal beam 11. This is favorable to reduce the probability of extrusion deformation of the battery device and improve the safety of the battery device.

[0036] In some embodiments of the present application, as shown in Figure 3 and Figure 4 The mounting longitudinal beam 11 is fixedly provided with a structural reinforcement 111. The structural reinforcement 111 and the corresponding support beam 30 are oppositely arranged along the width direction of the vehicle body assembly 1.

[0037] The mounting longitudinal beam 11 may be equipped with a structural reinforcement 111, which can be welded to the mounting longitudinal beam 11. The structural reinforcement 111 can improve the structural strength and impact resistance of the mounting longitudinal beam 11. The structural reinforcement 111 can be arranged opposite to the corresponding support beam 30 along the width direction of the vehicle body assembly 1. When the sill beam 20 is impacted and deforms, the sill beam 20 can deform and absorb energy towards the mounting longitudinal beam 11, and the support beam 30 can contact the mounting longitudinal beam 11 and transmit force to the mounting longitudinal beam 11. By setting the structural reinforcement 111, the impact resistance of the mounting longitudinal beam 11 can be improved, the probability of deformation and collapse of the mounting longitudinal beam 11 when the support beam 30 contacts the mounting longitudinal beam 11 can be reduced, and the probability of the mounting longitudinal beam 11 squeezing the battery device can be reduced, which is beneficial to improving the safety of the battery device and the vehicle.

[0038] In some embodiments of the present invention, the structural reinforcement 111 is disposed inside the mounting longitudinal beam 11.

[0039] The structural reinforcement 111 can be located inside the mounting longitudinal beam 11. The structural reinforcement 111 can support the mounting longitudinal beam 11, thereby improving the structural strength of the mounting longitudinal beam 11, reducing the probability of deformation when the mounting longitudinal beam 11 is under stress, and thus improving the safety of the battery device.

[0040] As an example, such as Figure 6 As shown, the structural reinforcement 111 may include a first plate 1111, a second plate 1112, a third plate 1113, a fourth plate, and a fifth plate 1114. The first plate 1111 may be correspondingly and spaced apart from the bottom wall of the mounting longitudinal beam 11 along the height direction of the body assembly 1. The first plate 1111 may be connected to the second plate 1112, the third plate 1113, the fourth plate, and the fifth plate 1114. The second plate 1112 and the fourth plate may be arranged opposite to each other and spaced apart along the width direction of the body assembly 1. The second plate 1112 may be located on the side of the structural reinforcement 111 away from the support beam 30, and the fourth plate may be located on the side of the structural reinforcement 111 facing the support beam 30. The third plate 1113 and the fifth plate 1114 may be arranged opposite to each other and spaced apart along the length direction of the body assembly 1. When the body assembly 1 is... Figure 2 When setting the direction, the length direction of body component 1 is... Figure 2The length direction of the vehicle body assembly 1 can be parallel to the length direction of the vehicle. The second plate body 1112, the third plate body 1113, the fourth plate body, and the fifth plate body 1114 can be sequentially connected along the circumferential direction of the structural reinforcement 111. The structural reinforcement 111 can define a first space with the bottom wall of the mounting longitudinal beam 11. By providing the first space, the dynamic stiffness of the structural reinforcement 111 can be improved, thereby improving the ability of the structural reinforcement 111 to support the mounting longitudinal beam 11, and further improving the structural strength of the mounting longitudinal beam 11.

[0041] In some embodiments of the present application, a plurality of support beams 30 are arranged between the rocker beam 20 and the corresponding mounting longitudinal beam 11, and the plurality of support beams 30 are sequentially arranged along the extension direction of the corresponding rocker beam 20.

[0042] The plurality of support beams 30 can be sequentially arranged along the extension direction of the corresponding rocker beam 20 (i.e., the length direction of the vehicle body assembly 1). By providing the plurality of support beams 30, the structural strength of the rocker beam 20 can be further improved, and the anti-impact ability of the rocker beam 20 can be improved. In addition, the plurality of support beams 30 can be arranged one-to-one with the plurality of structural reinforcements 111 along the width direction of the vehicle body assembly 1. Each support beam 30 has a corresponding structural reinforcement 111 arranged thereon, thereby reducing the probability of deformation of the mounting longitudinal beam 11 when the rocker beam 20 is impacted, and improving the anti-impact ability of the vehicle body assembly 1 and the safety of the battery device.

[0043] As an example, the plurality of support beams 30 can have various sizes, and the specific size of the support beam 30 can be adjusted according to the different positions of the support beam 30.

[0044] In some embodiments of the present application, the interval distance between any two adjacent support beams 30 among the plurality of support beams 30 arranged between the rocker beam 20 and the corresponding mounting longitudinal beam 11 is the same.

[0045] The plurality of support beams 30 can be uniformly arranged along the extension direction of the rocker beam 20, and the interval distance between any two adjacent support beams 30 can be the same. When the rocker beam 20 is impacted, the force on the rocker beam 20 is uniform, and the plurality of support beams 30 can jointly support the rocker beam 20, thereby reducing stress concentration, improving the stability of the structure of the rocker beam 20, and further improving the anti-impact ability of the rocker beam 20.

[0046] In some embodiments of the present application, the floor body 10 further has a floor 12, the mounting longitudinal beam 11 is fixedly arranged on the lower surface of the floor 12, the rocker beam 20 forms a support portion 21 protruding toward the side of the corresponding mounting longitudinal beam 11, the floor 12 is overlapped above the support portion 21, and the support beam 30 is located on the side of the corresponding support portion 21 away from the floor 12 and is spaced apart from the floor 12.

[0047] The floor body 10 further has a floor 12, the mounting longitudinal beam 11 can be connected with a lower surface of the floor 12, the mounting longitudinal beam 11 can be welded with the floor 12, and the mounting longitudinal beam 11 can be located below the floor 12.

As an example, when the connection between the floor 12 and the support portion 21 is sealed by glue, the glue can be applied to the connection between the floor 12 and the support portion 21 from the side of the lower surface of the floor 12, the glue-applied area of the connection between the floor 12 and the support portion 21 has a certain width, the glue-applied area can take the side edge of the support portion 21 facing the mounting longitudinal beam 11 as a center line, and the glue-applied area can extend along the extension direction of the rocker beam 20.

[0048] In the height direction of the vehicle body assembly 1, the support beam 30 can be located on the side of the support portion 21 away from the floor 12, the support beam 30 can be located below the floor 12, and the support beam 30 can be spaced apart from the floor 12, which can reduce the probability that the support beam 30 blocks the glue-applied area when the glue is applied, thereby improving the sealing between the floor 12 and the rocker beam 20.

[0049] In some embodiments of the present application, the end of the support beam 30 away from the corresponding rocker beam 20 and the end of the corresponding support portion 21 toward the corresponding mounting longitudinal beam 11 are aligned in the height direction of the vehicle body assembly 1.

[0050] The end of the support beam 30 away from the corresponding rocker beam 20 and the end of the corresponding support portion 21 toward the corresponding mounting longitudinal beam 11 can be aligned in the height direction of the vehicle body assembly 1, in other words, the end of the support beam 30 away from the corresponding rocker beam 20 and the end of the corresponding support portion 21 toward the corresponding mounting longitudinal beam 11 can be aligned in the width direction of the vehicle body assembly 1, when the connection between the rocker beam 20 and the floor 12 is sealed by glue, the support beam 30 does not block the connection between the rocker beam 20 and the floor 12, and the support beam 30 does not affect the glue sealing of the connection between the rocker beam 20 and the floor 12.

[0051] As an example, as shown in FIG. 6, the end of the support beam 30 away from the corresponding rocker beam 20 and the end of the corresponding support portion 21 toward the corresponding mounting longitudinal beam 11 are aligned in the height direction of the vehicle body assembly 1. Figure 5As shown, the support beam 30 can include a first sub-plate 31, a second sub-plate 32, a third sub-plate 33, a fourth sub-plate 34, and a fifth sub-plate 35. Along the width direction of the vehicle body assembly 1, the second sub-plate 32 is connected between the first sub-plate 31 and the third sub-plate 33. Along the height direction of the vehicle body assembly 1, the first sub-plate 31 and the third sub-plate 33 are respectively located on both sides of the second sub-plate 32. The second sub-plate 32 can be parallel to the floor 12, the first sub-plate 31 can be fixedly connected with the rocker beam 20, the first sub-plate 31 is attached to the rocker beam 20, an included angle is formed between the first sub-plate 31 and the second sub-plate 32, and the included angle can be an obtuse angle.

Along the length direction of the vehicle body assembly 1, the second sub-plate 32 can be connected between the fourth sub-plate 34 and the fifth sub-plate 35. Along the height direction of the vehicle body assembly 1, the fourth sub-plate 34 and the fifth sub-plate 35 can be located on the same side of the second sub-plate 32 facing the floor 12.

[0053] Along the width direction of the vehicle body assembly 1, the end of the support beam 30 away from the corresponding rocker beam 20 can be located outside the end of the support portion 21 toward the corresponding mounting longitudinal beam 11. It should be noted that along the width direction of the vehicle, the side toward the inside of the vehicle is the inner side, and the side toward the outside of the vehicle is the outer side. That is, the end of the support beam 30 away from the corresponding rocker beam 20 can be located on the side of the end of the support portion 21 away from the mounting longitudinal beam 11 toward the corresponding mounting longitudinal beam 11. The support beam 30 can avoid the rubber coating area along the width direction of the vehicle body assembly 1, which is beneficial to improve the integrity of the rubber coating area and the sealing between the floor 12 and the rocker beam 20.

[0054] In some embodiments of the present application, the support beam 30 and the corresponding support portion 21 are spaced apart.

[0055] The support beam 30 and the corresponding support portion 21 can be spaced apart, that is, the third sub-plate 33 can be spaced apart from the corresponding support portion 21. When the sealant is applied to the connection between the rocker beam 20 and the floor 12, the sealant can flow in the gap between the support beam 30 and the corresponding support portion 21. The support beam 30 does not hinder the application of sealant to the connection between the rocker beam 20 and the floor 12, and is more conducive to improving the sealing between the floor 12 and the rocker beam 20.

[0056] In some embodiments of the present application, the vehicle body assembly 1 can include a floor body 10, a rocker beam 20, a battery device, and a support beam 30.

[0057] According to the vehicle body assembly 1 of the vehicle of the embodiments of the present application, the rocker beam 20 is arranged on each side of the floor body 10 along the height direction of the vehicle body assembly 1, that is, the floor body 10 can be located between the two sides of the rocker beam 20 along the height direction of the vehicle body assembly 1. The floor body 10 can be welded to the rocker beam 20. The floor body 10 has a mounting longitudinal beam 11, and the mounting longitudinal beam 11 and the rocker beam 20 can be arranged opposite and spaced apart along the width direction of the vehicle body assembly 1.

The support beam 30 can support the rocker beam 20, and the support beam 30 can improve the strength and rigidity of the rocker beam 20. In the column impact test, when the rocker beam 20 is impacted, the rocker beam 20 deforms and absorbs energy. The support beam 30 can absorb and disperse the impact force, reduce the degree of indentation of the rocker beam 20, and the support beam 30 can transmit the force received by the rocker beam 20 to the mounting longitudinal beam 11, so as to realize force transmission.
