Therefore, the pole impact test is of great significance in automotive safety tests. Most of the existing vehicle sill beams do not have sufficient strength and stiffness to resist collisions, which affects the safety of the battery device. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present invention is to provide a vehicle body component of a vehicle, which can reduce the impact force transmitted from the sill beam to the mounting longitudinal beam, reduce the deformation of the mounting longitudinal beam, is conducive to reducing the probability of the battery device being extruded and deformed, and can improve the safety of the battery device.

[0029] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0030] Reference is made below to Figures 1-6 Describe a vehicle body assembly 1 of a vehicle according to an embodiment of the present invention. The vehicle body assembly 1 can be mounted on a vehicle.

[0031] For the vehicle body assembly 1 of a vehicle according to the first aspect embodiment of the present invention, as Figures 1-6 shown, the vehicle body assembly 1 of the vehicle can include: a floor main body 10, a door sill beam 20, and a support beam 30. Door sill beams 20 are provided on both opposite sides of the floor main body 10. The floor main body 10 and the door sill beam 20 are fixedly connected. The floor main body 10 has a mounting longitudinal beam 11 for mounting a battery device. The mounting longitudinal beam 11 and the door sill beam 20 are opposite and spaced apart along the width direction of the vehicle body assembly 1. A support beam 30 is provided between the door sill beam 20 and the corresponding mounting longitudinal beam 11. The support beam 30 is fixedly provided on the corresponding door sill beam 20 and is spaced apart from the corresponding mounting longitudinal beam 11.

[0032] It should be noted that in the related art, since the battery device of an electric vehicle is usually located at the bottom of the vehicle, when the vehicle is impacted circumferentially, it is easy to cause extrusion and deformation of the battery device, which may lead to battery short circuit or even fire. Therefore, the pole impact test is of great significance in vehicle safety tests. Most of the existing vehicle sill beams do not have sufficient strength and stiffness to resist collisions, affecting the safety of the battery device.

[0033] Based on this, an embodiment of the present application proposes a vehicle body assembly 1. Along the height direction of the body assembly 1, sill beams 20 are provided on both opposite sides of the floor main body 10, that is, the floor main body 10 can be located between the two sides of the sill beam 20 along the height direction of the body assembly 1. When the body assembly 1 is in the Figure 1 direction setting, the height direction of the body assembly 1 is the Figure 1 Z direction in Figure 2 and the height direction of the body assembly 1 can be parallel to the height direction of the vehicle. The sill beam 20 can be formed with a first flanging protruding towards the battery device along the width direction of the body assembly 1. The first flanging can be integrally formed with the sill beam 20, or the first flanging can be a separate part from the sill beam 20. When the body assembly 1 is in the Figure 2 direction setting, the width direction of the body assembly 1 is the X direction in and the width direction of the body assembly 1 can be parallel to the width direction of the vehicle. The first flanging can be located on the side of the sill beam 20 facing the battery device, and the first flanging can be located between the two sides of the sill beam 20 along the height direction of the body assembly 1. The floor main body 10 can overlap with the first flanging, the floor main body 10 can be welded to the first flanging, and the floor main body 10 can be fixedly connected to the sill beam 20 through the first flanging. The floor main body 10 has a mounting longitudinal beam 11, and the mounting longitudinal beam 11 can be used to mount the battery device. The mounting longitudinal beam 11 and the sill beam 20 can be relatively arranged and spaced apart along the width direction of the body assembly 1, and a first crush space can be formed between the mounting longitudinal beam 11 and the sill beam 20. When the sill beam 20 is impacted, the sill beam 20 can deform and absorb energy towards the first crush space.

[0034] A support beam 30 may be provided between the sill beam 20 and the corresponding mounting longitudinal beam 11. The sill beam 20 may be fixedly connected to the support beam 30. As an example, the support beam 30 may be welded to the sill beam 20. The support beam 30 may also be connected to the sill beam 20 by a flow drill screw process, which is beneficial to improving the connection strength between the support beam 30 and the sill beam 20 and can improve the impact resistance of the sill beam 20. The support beam 30 may be located within the first crush space. The support beam 30 may be spaced apart from the corresponding mounting longitudinal beam 11. The support beam 30 may support the sill beam 20 and may play a role in improving the strength and stiffness of the sill beam 20. When the sill beam 20 is impacted, the sill beam 20 may deform and absorb energy towards the inside of the first crush space. The support beam 30 may absorb and disperse the impact force, which can reduce the dent degree of the sill beam 20. As the sill beam 20 deforms, the support beam 30 may contact the mounting longitudinal beam 11, and the support beam 30 may crush and absorb energy. The sill beam 20 may transmit force to the mounting longitudinal beam 11 through the support beam 30, which can reduce the impact force received by the mounting longitudinal beam 11 and reduce the probability of deformation of the mounting longitudinal beam 11, thereby being beneficial to improving the vehicle reliability.

[0035] In the embodiment of the present application, the support beam 30 may support the sill beam 20 to improve the stiffness and strength of the sill beam 20. When the sill beam 20 is impacted, the sill beam 20 deforms and absorbs energy, and the support beam 30 may absorb and disperse the impact force received by the sill beam 20, which can reduce the dent degree of the sill beam 20. As the sill beam 20 deforms, when the support beam 30 contacts the mounting longitudinal beam 11, the support beam 30 may crush and absorb energy, which can reduce the impact force transmitted from the sill beam 20 to the mounting longitudinal beam 11 and reduce the deformation of the mounting longitudinal beam 11, being beneficial to reducing the probability of the battery device being extruded and deformed and can improve the safety of the battery device.

[0036] In some embodiments of the present invention, as Figure 3 and Figure 4 shown, a structural reinforcement 111 is fixedly provided on the mounting longitudinal beam 11, and the structural reinforcement 111 and the corresponding support beam 30 are disposed opposite to each other in the width direction of the vehicle body assembly 1.

[0037] The mounting longitudinal beam 11 may be provided with a structural reinforcement 111, which may be connected to the mounting longitudinal beam 11 by welding. The structural reinforcement 111 may improve the structural strength of the mounting longitudinal beam 11 and improve the anti-collision capability of the mounting longitudinal beam 11. The structural reinforcement 111 may be arranged relative to the corresponding support beam 30 along the width direction of the vehicle body assembly 1. When the sill beam 20 is impacted and deformed, the sill beam 20 may deform toward the mounting longitudinal beam 11 to absorb energy, and the support beam 30 may contact the mounting longitudinal beam 11, and the support beam 30 may transmit force to the mounting longitudinal beam 11. By providing the structural reinforcement 111, the anti-collision capability of the mounting longitudinal beam 11 may 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 may be reduced, and the probability of the mounting longitudinal beam 11 squeezing the battery device may be reduced, which is beneficial to improving the safety of the battery device and the safety of 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 arranged 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 and reducing the probability of deformation of the mounting longitudinal beam 11 when subjected to force, thereby improving the safety of the battery device.

[0040] As an example, 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 arranged corresponding to and spaced apart from the bottom wall of the mounting longitudinal beam 11 along the height direction of the vehicle body component 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 may be arranged opposite to and spaced apart from the fourth plate along the width direction of the vehicle body component 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 may be arranged opposite to and spaced apart from the fifth plate 1114 along the length direction of the vehicle body component 1. When the vehicle body component 1 is Figure 2 When setting the direction, the length direction of the body component 1 is Figure 2In the Y direction, the 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 and the bottom wall of the mounting longitudinal beam 11 can define a first space. By providing the first space, the dynamic stiffness of the structural reinforcement 111 can be improved, thereby enhancing 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 invention, a plurality of support beams 30 are provided between the sill beam 20 and the corresponding mounting longitudinal beam 11, and the plurality of support beams 30 are sequentially arranged along the extending direction of the corresponding sill beam 20.

[0042] There can be a plurality of support beams 30, and the plurality of support beams 30 can be sequentially arranged along the extending direction of the corresponding sill 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 sill beam 20 can be further improved, and the anti-impact ability of the sill beam 20 can be enhanced. And there can be a plurality of structural reinforcements 111, and the plurality of support beams 30 and the plurality of structural reinforcements 111 can be arranged in one-to-one correspondence along the width direction of the vehicle body assembly 1. Each support beam 30 has a corresponding structural reinforcement 111 provided therewith, thereby reducing the probability of deformation of the mounting longitudinal beam 11 when the sill beam 20 is impacted, which is beneficial to improving the anti-impact ability of the vehicle body assembly 1 and enhancing the safety of the battery device.

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

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

[0045] The plurality of support beams 30 can be evenly arranged along the extending direction of the sill beam 20, and the interval distance between any two adjacent support beams 30 can be the same. When the sill beam 20 is impacted, the sill beam 20 is uniformly stressed, and the plurality of support beams 30 can jointly support the sill beam 20, which can reduce stress concentration, be beneficial to improving the structural stability of the sill beam 20, and further enhance the anti-impact ability of the sill beam 20.

[0046] In some embodiments of the present invention, the floor main body 10 further has a floor 12, the mounting longitudinal beam 11 is fixedly provided on the lower surface of the floor 12, the sill beam 20 is formed with a support portion 21 protruding toward the side of the corresponding mounting longitudinal beam 11, the floor 12 is lapped 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 also has a floor 12. The mounting longitudinal beam 11 can be connected to the lower surface of the floor 12. The mounting longitudinal beam 11 can be welded to the floor 12. The mounting longitudinal beam 11 can be located below the floor 12. The floor 12 can be connected to the door sill beam 20. The door sill beam 20 can be formed with a support portion 21 (i.e., a first flange) protruding toward one side of the corresponding mounting longitudinal beam 11. The floor 12 can be overlapped above the support portion 21. The floor 12 can be welded to the support portion 21. The connection between the floor 12 and the support portion 21 needs to be sealed with glue, so as to improve the sealing between the floor 12 and the door sill beam 20 and reduce the probability of water leakage inside the vehicle. As an example, when applying glue to the connection between the floor 12 and the support portion 21, the glue can be applied from one side of the lower surface of the floor 12 to the connection between the floor 12 and the support portion 21. The glue-coated area at the connection between the floor 12 and the support portion 21 has a certain width. The glue-coated area can take the side edge of the support portion 21 facing the mounting longitudinal beam 11 as the center line, and the glue-coated area can extend along the extension direction of the door sill beam 20.

[0048] Along 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 of the support beam 30 blocking the glue coating area during glue coating, thereby improving the sealing between the floor 12 and the threshold beam 20.

[0049] In some embodiments of the present invention, the end of the support beam 30 facing 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 along the height direction of the vehicle body component 1 .

[0050] The end of the support beam 30 away from the corresponding sill beam 20 and the end of the corresponding support portion 21 toward the corresponding mounting longitudinal beam 11 can be aligned along the height direction of the vehicle body component 1. In other words, the end of the support beam 30 away from the corresponding sill beam 20 and the end of the corresponding support portion 21 toward the corresponding mounting longitudinal beam 11 can be aligned along the width direction of the vehicle body component 1. When the joint between the sill beam 20 and the floor 12 is sealed with glue, the support beam 30 does not block the joint between the sill beam 20 and the floor 12, and the support beam 30 does not affect the glue sealing at the joint between the sill beam 20 and the floor 12.

[0051] As an example, Figure 5As shown, the support beam 30 may 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 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 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 may be parallel to the floor 12, the first sub-plate 31 may be fixedly connected to the door sill beam 20, the first sub-plate 31 is fitted with the door sill beam 20, an angle is formed between the first sub-plate 31 and the second sub-plate 32, and the angle may be an obtuse angle, and an angle is formed between the third sub-plate 33 and the second sub-plate 32, and the angle may be a right angle. Along the length direction of the body assembly 1, the second sub-plate 32 may be connected between the fourth sub-plate 34 and the fifth sub-plate 35, and along the height direction of the body assembly 1, the fourth sub-plate 34 and the fifth sub-plate 35 may be located on the same side of the second sub-plate 32 facing the floor 12. The fourth sub-plate 34 can form an angle with the second sub-plate 32, which can be a right angle or an obtuse angle. The fifth sub-plate 35 can form an angle with the second sub-plate 32, which can be a right angle or an obtuse angle. The fourth sub-plate 34 is formed with a second flange 36, which is welded to the threshold beam 20. The fifth sub-plate 35 is formed with a third flange 37, which is welded to the threshold beam 20. The support beam 30 can be fixedly connected to the threshold beam 20 through the first sub-plate 31, the second flange 36, and the third flange 37.

[0052] In some embodiments of the present invention, Figure 2 As shown, along the width direction of the vehicle body component 1 , the end of the support beam 30 facing away from the corresponding rocker beam 20 is located outside the end of the corresponding support portion 21 facing the corresponding mounting longitudinal beam 11 .

[0053] Along the width direction of the vehicle body component 1, the end of the support beam 30 away from the corresponding threshold beam 20 can be located outside the end of the support portion 21 facing the corresponding mounting longitudinal beam 11. It should be noted that along the width direction of the vehicle, the side facing the inside of the vehicle is the inside, and the side facing the outside of the vehicle is the outside. That is, the end of the support beam 30 away from the corresponding threshold beam 20 can be located on the side of the end of the support portion 21 facing the corresponding mounting longitudinal beam 11 away from the mounting longitudinal beam 11. The support beam 30 can avoid the glue-coated area along the width direction of the vehicle body component 1, which is conducive to improving the integrity of the glue-coated area and the sealing between the floor 12 and the threshold beam 20.

[0054] In some embodiments of the present invention, 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-board 33 can be spaced apart from the corresponding support portion 21. When applying glue to the connection between the sill beam 20 and the floor 12, the sealant can flow in the gap between the support beam 30 and the corresponding support portion 21, and the support beam 30 will not hinder the application of glue to the connection between the sill beam 20 and the floor 12, which is more conducive to improving the sealing performance between the floor 12 and the sill beam 20.

[0056] In some embodiments of the present invention, the vehicle body assembly 1 may include: a floor main body 10, a sill beam 20, a battery device, and a support beam 30. Sill beams 20 are provided on both opposite sides of the floor main body 10, and the floor main body 10 and the sill beam 20 are fixedly connected. The floor main body 10 has mounting longitudinal beams 11, and the mounting longitudinal beams 11 and the sill beam 20 are opposite and spaced apart along the width direction of the vehicle body assembly 1. The mounting side beam of the battery device is located below the mounting longitudinal beam 11 and is mounted on the mounting longitudinal beam 11. The support beam 30 is fixedly connected to the corresponding sill beam 20, and the support beam 30 is connected to the corresponding mounting longitudinal beam 11 through the mounting side beam.

[0057] For the vehicle body assembly 1 according to the embodiment of the present application, along the height direction of the vehicle body assembly 1, sill beams 20 are provided on both opposite sides of the floor main body 10, that is, the floor main body 10 can be located between the two sides of the sill beam 20 along the height direction of the vehicle body assembly 1. The floor main body 10 can be welded to the sill beam 20. The floor main body 10 has mounting longitudinal beams 11, and the mounting longitudinal beams 11 and the sill beam 20 can be oppositely arranged and spaced apart along the width direction of the vehicle body assembly 1. A second crush space can be formed between the mounting longitudinal beam 11 and the sill beam 20, and the sill beam 20 can be deformed and absorb energy towards the second crush space. The battery device can be formed with a mounting side beam, the mounting side beam can be located below the mounting longitudinal beam 11, and the mounting side beam can be fixedly connected to the mounting longitudinal beam 11, so that the battery device can be mounted on the mounting longitudinal beam 11.

[0058] A support beam 30 can be provided between the sill beam 20 and the corresponding mounting longitudinal beam 11, and the support beam 30 can be located below the second crush space. Along the width direction of the vehicle body assembly 1, one end of the support beam 30 can be connected to the sill beam 20, the support beam 30 can be welded to the sill beam 20, and the other end of the support beam 30 can be connected to the mounting side beam, so that the support beam 30 can be connected to the corresponding mounting longitudinal beam 11 through the mounting side beam. The support beam 30 can support the sill beam 20, and the support beam 30 can play a role in improving the strength and stiffness of the sill beam 20. In the pillar collision test, when the sill beam 20 is impacted, the sill beam 20 deforms and absorbs energy, the support beam 30 can absorb and disperse the impact force, reduce the dent degree of the sill beam 20, and the support beam 30 can transfer the force received by the sill beam 20 to the mounting longitudinal beam 11, thereby realizing the transfer of force.
