Description

Technical Field

[0001] This application belongs to the field of vehicles, specifically relating to a crossbeam assembly and a vehicle. Background Technology

[0002] With the development of technology, vehicles have become a frequently used means of transportation for daily travel. Typically, vehicles are equipped with crossbeams and longitudinal beams. The crossbeams extend along the width of the vehicle, from the left wheel to the right wheel, while the longitudinal beams extend along the length of the vehicle, from the front to the rear. In related technologies, vehicle seats are usually mounted on seat mounting brackets, which are then mounted on the crossbeams. However, in these technologies, after the seat mounting brackets are connected to the crossbeams, installing the seats on the brackets becomes inconvenient, and the weight of the seat mounting brackets is significant, resulting in a higher overall vehicle weight and affecting the vehicle's mileage. Summary of the Invention

[0003] The purpose of this application is to provide a crossbeam assembly and a vehicle that at least solves the problem of inconvenience in installing seats on seat mounting brackets, and the fact that the large mass of the seat mounting brackets results in a large overall vehicle mass, affecting the vehicle's mileage.

[0004] In a first aspect, embodiments of this application provide a crossbeam assembly, the crossbeam assembly comprising: a crossbeam body and a seat mounting bracket;

[0005] The seat mounting bracket is fixed to the main body of the crossbeam;

[0006] The seat mounting bracket has a first cavity and a second cavity along a second direction, with a separating rib between the first cavity and the second cavity. The first cavity is away from the main body of the crossbeam, and the second cavity is close to the main body of the crossbeam.

[0007] Optionally, a reinforcing rib is provided in the first cavity, the first end of the reinforcing rib is connected to the isolation rib, the second end of the reinforcing rib is connected to the first cavity wall of the first cavity, and the isolation rib divides the first cavity into a first sub-cavity and a second sub-cavity. The first sub-cavity and the second sub-cavity are arranged side by side, and the volume of the first sub-cavity is greater than the volume of the second sub-cavity.

[0008] Optionally, the second cavity is provided with a plurality of supporting ribs, each of which is connected to the cavity wall of the second cavity at its opposite ends, and the plurality of supporting ribs divide the second cavity into a plurality of third sub-cavities, which are arranged side by side.

[0009] Optionally, the main body of the beam has a closed receiving cavity that extends along a first direction and is provided with a reinforcing member, wherein the first direction intersects with the second direction.

[0010] Optionally, the main body of the beam has a first sidewall and a second sidewall opposite each other along a third direction, and a third sidewall and a fourth sidewall opposite each other along a second direction. The first sidewall, the second sidewall, the third sidewall and the fourth sidewall are connected in sequence, and the first sidewall, the second sidewall, the third sidewall and the fourth sidewall enclose the receiving cavity, wherein the third direction, the second direction and the first direction intersect each other.

[0011] Optionally, the wall thickness of the third sidewall and the wall thickness of the fourth sidewall are both less than at least one of the wall thickness of the first sidewall and the wall thickness of the second sidewall.

[0012] Optionally, a first side plate is connected to the outer surface of the first side wall, and a second side plate is connected to the outer surface of the second side wall. The plane where the first side plate is located is parallel to the third direction, and the plane where the second side plate is located is parallel to the third direction. The first side plate, the second side plate, and the fourth side wall are an integral structure.

[0013] Wherein, the third direction intersects with the first direction.

[0014] Optionally, the main body of the crossbeam is a one-piece structure.

[0015] Optionally, the beam assembly further includes a beam joint;

[0016] The main body of the crossbeam has a first connecting end and a second connecting end along the first direction. Both the first connecting end and the second connecting end are connected to the crossbeam joint. The crossbeam joint is used to connect the main body of the crossbeam to the vehicle body.

[0017] Secondly, embodiments of this application provide a vehicle, the vehicle including a vehicle body and a beam assembly as described in any one of the first aspects above; the beam assembly is installed in the vehicle body.

[0018] In this embodiment, since the seat mounting bracket is fixed to the crossbeam body, after the crossbeam assembly is installed in the vehicle, the seat can be directly installed on the seat mounting bracket, allowing the seat to be supported by the crossbeam assembly, thus making the seat more stable. Furthermore, the seat mounting bracket has a first cavity and a second cavity along the second direction, with a separating rib between the first and second cavities. Therefore, the separating rib effectively divides the seat mounting bracket into a first cavity and a second cavity, with the first cavity away from the crossbeam body and the second cavity close to it. This allows the components connecting the seat and the seat mounting bracket to be located within the first cavity when installing the seat on the bracket, facilitating seat installation. Additionally, the presence of the second cavity reduces the weight of the seat mounting bracket, preventing a larger weight of the seat mounting bracket from leading to a larger weight of the crossbeam assembly and ultimately increasing the overall vehicle weight. That is, in this embodiment of the application, by fixing the seat mounting bracket to the main body of the crossbeam and setting the isolation rib plate in the seat mounting bracket, the seat mounting bracket has a first cavity and a second cavity. This not only makes the seat in the vehicle more stable to be supported, but also makes it easier to install the seat on the seat mounting bracket. Moreover, the seat mounting bracket has a small mass, which helps to reduce the overall vehicle mass and increase the vehicle's mileage. Attached Figure Description

Detailed Implementation

[0026] The terms "first" and "second" in the specification and claims of this application may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise stated, "multiple" means two or more. Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] like Figures 1 to 5As shown, the crossbeam assembly includes: a crossbeam body 10 and a seat mounting bracket 30; the seat mounting bracket 30 is fixed to the crossbeam body 10; the seat mounting bracket 30 has a first cavity 301 and a second cavity 302 along the second direction Y, and a separating rib plate 303 is provided between the first cavity 301 and the second cavity 302, the first cavity 301 is away from the crossbeam body 10, and the second cavity 302 is close to the crossbeam body 10.

[0030] The first cavity 301 and the second cavity 302 can be stacked.

[0031] In this embodiment, since the seat mounting bracket 30 is fixed to the crossbeam body 10, after the crossbeam assembly is installed in the vehicle, the seat can be directly installed on the seat mounting bracket 30, so that the seat is supported by the crossbeam assembly, thereby making the seat more stable. In addition, the seat mounting bracket 30 has a first cavity 301 and a second cavity 302 along the second direction Y, and there is a separating rib 303 between the first cavity 301 and the second cavity 302. Therefore, the seat mounting bracket 30 is effectively divided into the first cavity 301 and the second cavity 302 by the separating rib 303. The first cavity 301 is away from the crossbeam body 10, and the second cavity 302 is close to the crossbeam body 10. Thus, when the seat is installed on the seat mounting bracket 30, the component connecting the seat and the seat mounting bracket 30 can be located in the first cavity 301, which facilitates the installation of the seat. Furthermore, the presence of the second cavity 302 reduces the mass of the seat mounting bracket 30, avoiding the problem that a large mass of the seat mounting bracket 30 would lead to a large mass of the crossbeam assembly, ultimately increasing the mass of the vehicle. That is, in this embodiment of the application, by fixing the seat mounting bracket 30 to the crossbeam body 10 and providing the isolation rib plate 303 in the seat mounting bracket 30, the seat mounting bracket 30 has a first cavity 301 and a second cavity 302. This not only makes the seat in the vehicle more stable to be supported, but also facilitates the installation of the seat on the seat mounting bracket 30. In addition, the seat mounting bracket 30 has a small mass, which helps to reduce the overall weight of the vehicle and increase the driving range of the vehicle.

[0032] It should be noted that, in this embodiment of the application, the seat mounting bracket 30 can be fixed to the crossbeam body 10 by the FDS connection process. Specifically, the seat mounting bracket 30 is threadedly connected to the crossbeam body 10 by the high-speed rotation of screws, so that the seat mounting bracket 30 is fixed on the crossbeam body 10.

[0033] Furthermore, in this embodiment, the number of seat mounting brackets 30 can be set according to actual needs. For example, if there are four seat mounting brackets 30, one seat of the vehicle can be installed on every two seat mounting brackets 30, thus two seats can be installed on the main body 10 along the first direction X. Alternatively, if there are six seat mounting brackets 30, one seat of the vehicle can be installed on every two seat mounting brackets 30, thus three seats can be installed on the main body along the first direction X. The specific number of seat mounting brackets 30 is not limited in this embodiment.

[0034] In addition, in some embodiments, the beam body 10 may have a closed receiving cavity that extends along a first direction X and is provided with a reinforcing member 20 to enhance the rigidity of the beam body 10. The first direction X intersects with the second direction Y.

[0035] In this embodiment, since the crossbeam body 10 has a closed receiving cavity that extends along the first direction X, a reinforcing member 20 can be provided in the receiving cavity. The reinforcing member 20 improves the bending resistance and stiffness of the crossbeam body 10, making it less prone to deformation. Therefore, when the crossbeam body 10 is used in a vehicle, if the vehicle is impacted from the side, the end of the crossbeam body 10 will be subjected to force, but the stiffness and bending resistance of the crossbeam body 10 are enhanced by the foam-like reinforcing member 20, making it less prone to deformation and thus improving vehicle safety. In other words, in this embodiment, by making the crossbeam body 10 have a closed receiving cavity and providing a reinforcing member 20 in the receiving cavity, the stiffness and bending resistance of the crossbeam body 10 can be effectively improved, making it less prone to deformation. Therefore, after the crossbeam body 10 is installed in a vehicle, vehicle safety can be effectively improved.

[0036] In addition, in the related art, the crossbeam assembly includes a crossbeam main body, and the cross-section of the crossbeam main body is in a "ji" shape. Here, the cross-section of the crossbeam main body refers to the cross-section perpendicular to the extending direction of the crossbeam main body. That is, in the related art, the crossbeam main body may include a first side plate, a second side plate, and a third side plate. The first side plate, the second side plate, and the third side plate are connected in sequence, and the first side plate, the second side plate, and the third side plate enclose a U shape. Then, a connecting plate is connected to the first side plate and a connecting plate is connected to the second side plate, so that the cross-section of the crossbeam main body is in a "ji" shape. However, in the related art, after the crossbeam assembly is installed in a vehicle, once the side of the vehicle is impacted, the stiffness of the crossbeam assembly is reduced, and the crossbeam assembly is easily deformed, resulting in a reduction in the safety of the vehicle. In the embodiment of the present application, by making the crossbeam main body 10 have a closed receiving cavity and arranging a reinforcing member 20 in the receiving cavity, the stiffness of the crossbeam main body 10 and the bending resistance of the crossbeam main body 10 can be effectively improved, so that the crossbeam main body 10 is not easily deformed. Furthermore, after the crossbeam main body 10 is installed in a vehicle, the safety of the vehicle can be effectively improved.

[0037] It should be noted that in the embodiment of the present application, the shape of the cross-section of the crossbeam main body 10 may be in a "kou" shape. Here, the cross-section of the crossbeam main body 10 is: the cross-section perpendicular to the first direction X. Of course, the shape of the cross-section of the crossbeam main body 10 may also be other shapes. For example, the cross-section of the crossbeam main body 10 is a pentagon, or for another example, the cross-section of the crossbeam main body 10 is a hexagon. The specific shape of the cross-section of the crossbeam main body 10 is not limited in the embodiment of the present application. Here, the first direction X is the direction parallel to the axis direction of the crossbeam main body 10.

[0038] In addition, in the embodiment of the present application, the reinforcing member 20 may be a foam-shaped reinforcing member 20. The foam-shaped reinforcing member 20 may be a metal foam material. For example, the foam-shaped reinforcing member 20 is foam aluminum, or for another example, the foam-shaped reinforcing member 20 is foam copper. This is not limited in the embodiment of the present application. In addition, when the reinforcing member 20 may be a foam-shaped reinforcing member 20, the foam-shaped reinforcing member 20 may fill the receiving cavity, so that the improvement effect on the stiffness and bending resistance of the crossbeam main body is better.

[0039] In addition, in the embodiment of the present application, by filling the foam-shaped reinforcing member 20 in the receiving cavity, not only can the stiffness of the crossbeam main body 10 be strengthened, but also the property that the foam-shaped reinforcing member 20 has a relatively light mass can be utilized, so that the mass of the crossbeam assembly is relatively light, avoiding the problem that the mass of the crossbeam assembly is too large and finally leading to an excessive mass of the vehicle.

[0040] In addition, in some embodiments, such as Figure 2As shown, the main body 10 of the beam has a first sidewall 11 and a second sidewall 12 along the third direction Z, and a third sidewall 13 and a fourth sidewall 14 along the second direction Y. The first sidewall 11, the second sidewall 12, the third sidewall 13, and the fourth sidewall 14 are connected sequentially, and the first sidewall 11, the second sidewall 12, the third sidewall 13, and the fourth sidewall 14 enclose a cavity. The third direction Z, the second direction Y, and the first direction X intersect each other. By setting the first sidewall 11, the second sidewall 12, the third sidewall 13, and the fourth sidewall 14 to be connected sequentially, it is equivalent to making the first sidewall 11, the second sidewall 12, the third sidewall 13, and the fourth sidewall 14 enclose a cavity, which can be easily formed into a closed cavity. This ensures that the foam-like reinforcing member 20 set in the cavity is not prone to leakage, thereby ensuring that the foam-like reinforcing member 20 effectively increases the rigidity of the main body 10 of the beam, and also makes the cross section of the main body 10 of the beam "U" shaped.

[0041] In some embodiments, the wall thickness of the third sidewall 13 and the wall thickness of the fourth sidewall 14 are both less than at least one of the wall thickness of the first sidewall 11 and the wall thickness of the second sidewall 12. That is, the wall thickness of the third sidewall 13 and the wall thickness of the fourth sidewall 14 are both less than the wall thickness of the first sidewall 11, and the wall thickness of the third sidewall 13 and the wall thickness of the fourth sidewall 14 are both less than the wall thickness of the second sidewall 12.

[0042] Furthermore, after the crossbeam assembly is installed in the vehicle, the third direction Z is parallel to the length direction of the vehicle, and the second direction Y is parallel to the height direction of the vehicle. The crossbeam body 10 needs to support other components of the vehicle, such as the seats, in the height direction, thus requiring the crossbeam body 10 to have high rigidity in the height direction. When the crossbeam assembly is installed in the vehicle, the first sidewall 11 and the second sidewall 12 are sidewalls in the height direction of the vehicle, playing a major supporting role when the crossbeam assembly supports components. Therefore, the wall thickness of the third sidewall 13 and the fourth sidewall 14 are both less than the wall thickness of the first sidewall 11, and the wall thickness of the third sidewall 13 and the fourth sidewall 14 are both less than the wall thickness of the second sidewall 12, making the crossbeam body 10 have high rigidity in the height direction of the vehicle, thereby preventing the crossbeam body 10 from easily deforming. That is, by setting the wall thickness of the third side wall 13 and the fourth side wall 14 to be less than the wall thickness of the first side wall 11, and the wall thickness of the third side wall 13 and the fourth side wall 14 to be less than the wall thickness of the second side wall 12, the rigidity of the main body of the crossbeam 10 can be effectively improved, and the material used for processing the main body of the crossbeam 10 can be saved, thus reducing costs.

[0043] It should be noted that the length direction of the vehicle is from the front to the rear, and the height direction is from the roof to the bottom.

[0044] Alternatively, in this embodiment, the wall thickness of the third sidewall 13 can be equal to the wall thickness of the first sidewall 11, the wall thickness of the fourth sidewall 14 can be equal to the wall thickness of the first sidewall 11, and the wall thickness of the first sidewall 11 can be equal to the wall thickness of the second sidewall 12, which is equivalent to making the wall thickness of the sidewalls of the main beam 10 relatively thick. Alternatively, in this embodiment, the wall thickness of the first sidewall 11 may not be equal to the wall thickness of the second sidewall 12, and the wall thickness of the third sidewall 13 may not be equal to the wall thickness of the fourth sidewall 14; this embodiment does not limit the specific thickness of the sidewalls in this case.

[0045] For example, the wall thickness of the first sidewall 11 is 3mm, the wall thickness of the second sidewall 12 is 3mm, the wall thickness of the third sidewall 13 is 2.5mm, and the wall thickness of the fourth sidewall 14 is 2.5mm.

[0046] In some embodiments, the crossbeam body 10 is a one-piece structure. This design reduces the number of parts in the crossbeam assembly, thereby lowering the connection cost of the crossbeam assembly. Furthermore, the one-piece structure helps to improve the strength of the crossbeam body 10, resulting in higher strength.

[0047] It should be noted that, in the embodiments of this application, the crossbeam body 10 can be formed by extruding aluminum, and the crossbeam body 10 is integrally formed, thereby improving the strength of the crossbeam body 10 while reducing its weight.

[0048] In addition, in this embodiment of the application, when the main body 10 of the crossbeam has a first sidewall 11 and a second sidewall 12 along the third direction Z, and the main body 10 of the crossbeam has a third sidewall 13 and a fourth sidewall 14 along the second direction Y, the seat mounting bracket 30 can be located on the third sidewall 13, and connecting portions extend from both sides of the seat mounting bracket, one connecting portion is connected to the first sidewall 11, and the other connecting portion is connected to the second sidewall 12.

[0049] In addition, in some embodiments, a reinforcing rib 304 is provided in the first cavity 301. The first end of the reinforcing rib 304 is connected to the isolation rib 303, and the second end of the reinforcing rib 304 is connected to the first cavity wall of the first cavity 301. The isolation rib 303 divides the first cavity 301 into a first sub-cavity 3011 and a second sub-cavity 3012. The first sub-cavity 3011 and the second sub-cavity 3012 are arranged side by side. The volume of the first sub-cavity 3011 is greater than the volume of the second sub-cavity 3012. The first cavity wall is the cavity wall opposite to the isolation rib 303 in the second direction Y.

[0050] Since the first end of the reinforcing rib 304 is connected to the isolation rib 303, and the second end of the reinforcing rib 304 is connected to the first cavity wall of the first cavity 301, the first cavity 301 is effectively divided into a first sub-cavity 3011 and a second sub-cavity 3012 by the reinforcing rib 304. This allows the first sub-cavity 3011 and the second sub-cavity 3012 to be arranged side by side, and the reinforcing rib 304 can provide support, thereby increasing the strength of the first cavity 301 and thus the strength of the seat mounting frame 30, preventing the seat mounting frame 30 from easily deforming. In addition, the volume of the first sub-cavity 3011 is larger than the volume of the second sub-cavity 3012, so that when the seat is mounted on the seat mounting frame 30, the floating nut box for mounting the seat can be located in the first sub-cavity 3011, ensuring that the first sub-cavity 3011 has sufficient space to accommodate the floating nut box, thus facilitating the mounting of the seat on the seat mounting frame 30.

[0051] In addition, in this embodiment of the application, along the first direction X, the first cavity 301 has a first opening and a second opening, both of which are in communication with the outside of the seat mounting frame 30, so that both the first sub-cavity 3011 and the second sub-cavity 3012 are in communication with the outside of the seat mounting frame 30.

[0052] Additionally, in some embodiments, such as Figure 3 As shown, a plurality of support ribs 305 are provided in the second cavity 302. The two opposite ends of each support rib 305 are respectively connected to the cavity wall of the second cavity 302, and the plurality of support ribs 305 divide the second cavity 302 into a plurality of third sub-cavities 3021, which are arranged side by side.

[0053] Since each supporting rib 305 is connected to the cavity wall of the second cavity 302 at its opposite ends, it is equivalent to dividing the second cavity 302 into multiple third sub-cavities 3021 by multiple supporting ribs 305. These multiple third sub-cavities 3021 are arranged side-by-side, and the multiple supporting ribs 305 effectively enhance the rigidity of the seat mounting bracket 30. Furthermore, after the seat is installed on the seat mounting bracket, the multiple supporting ribs 305 improve the seat's modal characteristics, preventing seat vibration and abnormal noise during vehicle operation. In other words, by providing multiple supporting ribs 305 in the second cavity 302, it is beneficial to improve the rigidity of the seat mounting bracket 30 and the modal characteristics of the seat.

[0054] It should be noted that the number of supporting ribs 305 can be set according to actual needs. For example, the number of supporting ribs 305 can be 3, or even 4. The specific number of supporting ribs 305 is not limited in this embodiment. When there are 3 supporting ribs 305, the 3 supporting ribs 305 can divide the second cavity 302 into 4 third sub-cavities 3021, and the supporting ribs 305 can be arranged such that the cross-sectional shape of each third sub-cavity 3021 is triangular. Of course, the cross-sectional shape of the third sub-cavity 3021 can also be other shapes, for example, a quadrilateral. This is not limited in this embodiment.

[0055] Additionally, in some embodiments, such as Figure 1 As shown, the crossbeam assembly also includes a crossbeam connector 40; the crossbeam body 10 has a first connecting end 101 and a second connecting end 102 along the first direction X, and both the first connecting end 101 and the second connecting end 102 are connected to the crossbeam connector 40. The crossbeam connector 40 is used to connect the crossbeam body 10 to the vehicle body.

[0056] Since both the first connecting end 101 and the second connecting end 102 are connected to crossbeam connectors 40, when it is necessary to install the crossbeam body 10 in a vehicle, the crossbeam connector 40 of the first connecting end 101 of the crossbeam body 10 can be directly connected to the vehicle body, and the crossbeam connector 40 of the second connecting end 102 of the crossbeam body 10 can be connected to the vehicle body, thereby completing the installation of the crossbeam body 10 in the vehicle body. That is, by setting the crossbeam connector 40, it is convenient to install the crossbeam body 10 in the vehicle body.

[0057] It should be noted that the shape of the beam connector 40 can be set according to actual needs; for example, the beam connector 40 can be L-shaped. The specific shape of the beam connector 40 is not limited in this embodiment. Furthermore, the beam connector 40 and the beam body 10 can be connected using the FDS process.

[0058] Additionally, in some embodiments, such as Figure 1 As shown, the crossbeam assembly also includes a battery mounting sleeve 50, which is fixed to the crossbeam body 10 and is used to mount the vehicle's battery pack.

[0059] Since the battery mounting sleeve 50 is fixed to the crossbeam body 10, after the crossbeam body 10 is installed in the vehicle body, the vehicle's battery pack can be installed in the battery mounting sleeve 50. Thus, the battery mounting sleeve 50 provides an installation position for the battery pack, facilitating battery pack installation. Furthermore, the battery mounting sleeve 50 being fixed to the crossbeam body 10 can effectively improve the rigidity requirements of the battery pack installation point, and the crossbeam effectively supports the battery pack, ensuring that the battery pack is relatively stable in the vehicle body.

[0060] It should be noted that the number of battery mounting sleeves 50 can be set according to actual needs. For example, there can be four battery mounting sleeves 50, which are spaced apart on the main body of the crossbeam 10. Alternatively, there can be six battery mounting sleeves 50. The specific number of battery mounting sleeves 50 is not limited in this embodiment.

[0061] Additionally, in some embodiments, such as Figure 1 and Figure 2 As shown, the main body 10 of the crossbeam has a first sidewall 11 and a second sidewall 12 along the third direction Z. The outer surface of the first sidewall 11 is connected to a first side plate 60, and the outer surface of the second sidewall 12 is connected to a second side plate 70. The plane of the first side plate 60 is parallel to the third direction Z, and the plane of the second side plate 70 is parallel to the third direction Z. Both the first side plate 60 and the second side plate 70 are used to connect to the floor in the vehicle body. The first side plate 70, the second side plate 60, and the fourth sidewall 14 are an integral structure. The third direction Z intersects with the first direction X.

[0062] Since the outer surface of the first side wall 11 is connected to the first side plate 60, and the outer surface of the second side wall 12 is connected to the second side plate 70, when the crossbeam body 10 is installed in the vehicle, the first side plate 60 and the second side plate 70 can be connected to the floor of the vehicle body, making the crossbeam body 10 more firmly connected in the vehicle body and less prone to shaking. In other words, by setting the first side plate 60 and the second side plate 70, the crossbeam body 10 can be more firmly connected when installed in the vehicle body. Furthermore, the first side plate 70, the second side plate 60, and the fourth side wall 14 are an integral structure, which increases the strength of the crossbeam body 10 and helps improve its rigidity.

[0063] It should be noted that the first side plate 60 can be connected to the vehicle floor using a self-punching riveting process. Alternatively, the first side plate 60 can also be connected to the vehicle floor using an SPR welding process. The specific method of connecting the first side plate 60 to the vehicle floor is not limited in this embodiment. Furthermore, the method of connecting the second side plate 70 to the vehicle floor can refer to the method of connecting the first side plate 60 to the vehicle floor, and will not be repeated here.

[0064] Furthermore, in this embodiment, the widths of the first side plate 60 and the second side plate 70 can be set according to actual needs. The width of the first side plate 60 is the distance between the end of the first side plate 60 away from the first side wall 11 and the end of the first side plate 60 connected to the first side wall 11. The width of the second side plate 70 is the distance between the end of the second side plate 70 away from the second side wall 12 and the end of the second side plate 70 connected to the second side wall 12. For example, the width of the first side plate 60 is 23mm, and the width of the second side plate 70 is 23mm; or, for another example, the width of the first side plate 60 is 25mm, and the width of the second side plate 70 is 25mm. This embodiment does not limit the specific width of the second side plate 70.

[0065] In addition, in this embodiment, reinforcing ribs can be provided in the receiving cavity of the beam body 10, which can further improve the rigidity of the beam body 10. That is, in this embodiment, both reinforcing ribs and foam-like reinforcing members 20 can be provided in the receiving cavity of the beam body 10.

[0066] In this embodiment, since the seat mounting bracket 30 is fixed to the crossbeam body 10, after the crossbeam assembly is installed in the vehicle, the seat can be directly installed on the seat mounting bracket 30, so that the seat is supported by the crossbeam assembly, thereby making the seat more stable. In addition, the seat mounting bracket 30 has a first cavity 301 and a second cavity 302 along the second direction Y, and there is a separating rib 303 between the first cavity 301 and the second cavity 302. Therefore, the seat mounting bracket 30 is effectively divided into the first cavity 301 and the second cavity 302 by the separating rib 303. The first cavity 301 is away from the crossbeam body 10, and the second cavity 302 is close to the crossbeam body 10. Thus, when the seat is installed on the seat mounting bracket 30, the component connecting the seat and the seat mounting bracket 30 can be located in the first cavity 301, which facilitates the installation of the seat. Furthermore, the presence of the second cavity 302 reduces the mass of the seat mounting bracket 30, avoiding the problem that a large mass of the seat mounting bracket 30 would lead to a large mass of the crossbeam assembly, ultimately increasing the mass of the vehicle. That is, in this embodiment of the application, by fixing the seat mounting bracket 30 to the crossbeam body 10 and providing the isolation rib plate 303 in the seat mounting bracket 30, the seat mounting bracket 30 has a first cavity 301 and a second cavity 302. This not only makes the seat in the vehicle more stable to be supported, but also facilitates the installation of the seat on the seat mounting bracket 30. In addition, the seat mounting bracket 30 has a small mass, which helps to reduce the overall weight of the vehicle and increase the driving range of the vehicle.

Furthermore, a seat may be provided in the vehicle body, and the seat is connected to the seat mounting bracket 30. Additionally, a battery pack may be provided in the vehicle body, and the battery pack is mounted on the battery mounting sleeve 50.
