[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein 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 accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] The following is for reference. Figures 1-4 The description includes a side crossbeam 9 of a vehicle according to an embodiment of the present invention, the side crossbeam 9 being constructed as part of the front lower crossbeam assembly 98 of the vehicle.

[0032] like Figures 1-4 As shown, the side beam 9 according to an embodiment of the present utility model includes: a side beam body 91.

[0033] The side beam body 91 includes a first sub-body 92 and a second sub-body 94. The first sub-body 92 defines a first cavity 921, and the second sub-body 94 defines a second cavity 941. The first sub-body 92 and the second sub-body 94 are arranged and connected along a first direction. The first sub-body 92 includes a first reinforcing member 922, and the second sub-body 94 includes a second reinforcing member 942. Both the first reinforcing member 922 and the second reinforcing member 942 extend along a second direction. The first reinforcing member 922 is disposed in the first cavity 921, and the second reinforcing member 942 is disposed in the second cavity 941. The first direction is perpendicular to the second direction.

[0034] The side beam body 91 includes a first sub-body 92 and a second sub-body 94. The first sub-body 92 and the second sub-body 94 are connected. The connection method of the first sub-body 92 and the second sub-body 94 can be, but is not limited to, welding, snap-fitting, riveting, etc. As some embodiments of this application, the first sub-body 92 and the second sub-body 94 are connected by bolts. As some embodiments of this application, the first sub-body 92 and the second sub-body 94 are integrally formed.

[0035] Along the first direction (i.e.) Figure 1 The first sub-body 92 and the second sub-body 94 are arranged in the X direction shown in the figure. As some embodiments of this application, the first direction is the length direction of the vehicle, that is, the X direction of the vehicle. Figure 1 (in the X direction shown), the first sub-body 92 is located in front of the second sub-body 94.

[0036] The first sub-body 92 defines a first cavity 921, and the second sub-body 94 defines a second cavity 941. The first cavity 921 and the second cavity 941 are not connected to each other, and, along the first direction (i.e., Figure 1 (As shown in the X direction), the first cavity 921 is open at one end away from the second cavity 941, and the second cavity 941 is open at one end away from the first cavity 921.

[0037] The first sub-body 92 includes a first reinforcing member 922, and the second sub-body 94 includes a second reinforcing member 942. Both the first reinforcing member 922 and the second reinforcing member 942 are along a second direction (i.e., Figure 1 As shown in the Y direction) extension configuration, as some embodiments of this application, the second direction (i.e. Figure 1 The Y direction shown is the width direction of the vehicle, which is the Y direction of the vehicle. The first reinforcing member 922 is provided in the first cavity 921, and the second reinforcing member 942 is provided in the second cavity 941. As some embodiments of this application, the side beam body 91 is constructed as an integrally formed part.

[0038] As some embodiments of this application, the number of side beams 9 can be two, with the two side beams 9 along the second direction (i.e. Figure 1 The two side beams 9 are arranged symmetrically and at intervals in the Y direction (as shown), with the middle beam 8 connecting between the two side beams 9 to form the front lower beam assembly 98.

[0039] It should be noted that the first sub-body 92 and the second sub-body 94 define the first cavity 921 and the second cavity 941 respectively, and the first reinforcing member 922 is positioned along the second direction (i.e., Figure 1 The second reinforcing member 942 extends along the second direction (i.e., the Y direction shown) and is disposed in the first cavity 921, and the second reinforcing member 942 extends along the second direction (i.e., the Y direction shown) and is disposed in the second cavity 921. Figure 1 Extending in the Y direction and located in the second cavity 941, when a vehicle collides, the force of the frontal collision is transmitted along the tower to the lower front crossbeam assembly 98, and then transmitted along the Y direction of the vehicle to the A-pillar via the first reinforcing member 922 and the second reinforcing member 942 of the side crossbeam body 91. Moreover, not only can the first reinforcing member 922 and the second reinforcing member 942 transmit force along the Y direction of the vehicle, but the first top plate 923 and the first bottom plate 924 of the first cavity 921 and the second top plate 943 and the second bottom plate 944 of the second cavity 941 can also transmit force along the Y direction of the vehicle. This arrangement can enhance the rigidity of the overall body structure, reduce the deformation of the body structure under collision or dynamic load, which is beneficial to improving the stability and safety of the body. In addition, it can effectively disperse and absorb collision energy, reduce the direct impact on the passenger compartment, and thus protect the safety of the occupants. Furthermore, during vehicle operation, especially at high speed or during sharp turns, it can enhance the lateral stability of the vehicle, reduce body roll and sway, and improve driving handling and comfort.

[0040] Therefore, when a vehicle collides, the force of the collision will be transmitted to the A-pillar through the first reinforcing member 922 and the second reinforcing member 942. The force transmission performance is better, and it can effectively disperse and absorb the impact energy, resulting in better safety. It also helps to improve the lateral stability of the vehicle and improve the handling and comfort of the driver.

[0041] In some embodiments of this utility model, such as Figure 2 As shown, there is one first reinforcing member 922, or there are multiple first reinforcing members 922, with the multiple first reinforcing members 922 along a third direction (i.e. Figure 1 The Z-direction (as shown) is spaced apart, and the third direction (i.e. Figure 1 The Z direction shown) and the first direction (i.e. Figure 1 The X direction shown), the second direction (i.e. Figure 1 The Y-direction shown is perpendicular to all directions.

[0042] In other words, the number of first reinforcing members 922 can be, but is not limited to, one, two, three, etc. As some embodiments of this application, the number of first reinforcing members 922 is one, and one first reinforcing member 922 is along the second direction (i.e., Figure 1 (Extends in the Y direction as shown).

[0043] As some embodiments of this application, the number of first reinforcing members 922 is three, and all three first reinforcing members 922 are along the second direction (i.e., Figure 1 The three first reinforcing members 922 extend along the third direction (i.e., the Y direction shown), and extend along the third direction (i.e., the Y direction shown). Figure 1 The arrangement is spaced out in the Z direction as shown.

[0044] As some embodiments of this application, a third party (i.e.) Figure 1 The Z-direction shown is the vehicle's height direction, i.e., the vehicle's Z-direction. The third direction (i.e....) Figure 1 The Z direction shown) and the first direction (i.e. Figure 1 The X direction shown), the second direction (i.e. Figure 1 The Y-direction shown is perpendicular to all other directions, meaning that the third direction (i.e., the Y-direction) is perpendicular to all other directions. Figure 1 The Z direction shown), the first direction (i.e. Figure 1 The X direction shown), the second direction (i.e. Figure 1 The Y-directions shown are perpendicular to each other.

[0045] This configuration increases the Y-axis force transmission path of the side beam 9, which is beneficial to improving the structural strength and force transmission performance of the side beam 9.

[0046] In some embodiments of this utility model, such as Figure 2As shown, the first sub-body 92 includes: a first base plate 924 and a first top plate 923. The first base plate 924 includes: a first sub-base plate 925 and a second sub-base plate 926. The distance between the first sub-base plate 925 and the first top plate 923 is greater than the distance between the second sub-base plate 926 and the first top plate 923.

[0047] Among them, along the third direction (i.e. Figure 1 (As shown in the Z direction), the distance between the first sub-bottom plate 925 and the first top plate 923 is greater than the distance between the second sub-bottom plate 926 and the first top plate 923.

[0048] As some embodiments of this application, among the plurality of first reinforcing members 922, one first reinforcing member 922 is along the second sub-base plate 926 in the second direction (i.e., Figure 1 The Y direction shown is aligned and connected.

[0049] By making the distance between the first sub-base plate 925 and the first top plate 923 greater than the distance between the second sub-base plate 926 and the first top plate 923, the first sub-base plate 925 and the second sub-base plate 926 can be aligned along a third direction (i.e., Figure 1 The staggered arrangement (in the Z direction as shown) allows the height of the first sub-base plate 925 to match the height of the bottom surface of the tower package, and the height of the second sub-base plate 926 to match the height of the bottom surface of the A-column. This facilitates the transmission of collision force from the tower package to the side beam 9, and from the side beam 9 to the A-column, thereby improving the force transmission performance of the side beam 9.

[0050] In some embodiments of this utility model, such as Figure 3 As shown, there is one second reinforcing member 942, or there are multiple second reinforcing members 942, with the multiple second reinforcing members 942 along a third direction (i.e. Figure 1 (as shown in the Z direction) spaced rows.

[0051] In other words, the number of the second reinforcing member 942 can be, but is not limited to, one, two, three, etc. As some embodiments of this application, the number of the second reinforcing member 942 is one, and one second reinforcing member 942 is along the second direction (i.e., Figure 1 The Y-direction extension setting is shown.

[0052] As some embodiments of this application, the number of second reinforcing members 942 is three, and all three second reinforcing members 942 are along the second direction (i.e., Figure 1 The three second reinforcing members 942 extend along the third direction (i.e., the Y direction shown), and extend along the third direction (i.e., the Y direction shown). Figure 1 The arrangement is spaced out in the Z direction as shown.

[0053] This configuration increases the Y-axis force transmission path of the side beam 9, which is beneficial to improving the structural strength and force transmission performance of the side beam 9.

[0054] In some embodiments of this utility model, such as Figure 3 As shown, the second sub-body 94 includes: a second base plate 944 and a second top plate 943. The second base plate 944 includes: a third sub-base plate 945 and a fourth sub-base plate 946. The distance between the third sub-base plate 945 and the second top plate 943 is greater than the distance between the fourth sub-base plate 946 and the second top plate 943. Furthermore, the third sub-base plate 945 and the second sub-base plate 946 are aligned along a first direction (i.e.,...). Figure 1 The X direction shown is directly opposite and connected.

[0055] Among them, along the third direction (i.e. Figure 1 (as shown in the Z direction), the distance between the third sub-base plate 945 and the second top plate 943 is greater than the distance between the fourth sub-base plate 946 and the second top plate 943, and the third sub-base plate 945 and the second sub-base plate 926 are along the first direction (i.e., Figure 1 The X direction shown is directly opposite and connected, meaning that the third sub-base plate 945 and the second sub-base plate 926 have the same height.

[0056] As some embodiments of this application, a second reinforcing member 942 and a fourth sub-base plate 946 are along a second direction (i.e., Figure 1 The Y direction shown is aligned and connected.

[0057] As some embodiments of this application, the third sub-base plate 945 and the second sub-base plate 926 are constructed as an integral molded part, so that the third sub-base plate 945 and the second sub-base plate 926 are facing each other and connected along the second direction.

[0058] This arrangement allows the heights of the third sub-base plate 945 and the second sub-base plate 926 to match the height of the bottom surface of the A-pillar, which is beneficial for the side beam 9 to transmit the collision force to the A-pillar and can improve the force transmission performance of the side beam 9. By making the distance between the third sub-base plate 945 and the second top plate 943 greater than the distance between the fourth sub-base plate 946 and the second top plate 943, it is convenient to install other components at the bottom of the fourth sub-base plate 946.

[0059] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the second sub-body 94 also includes a first mounting member 947, which is adapted to be assembled with the vehicle's power battery.

[0060] The first mounting member 947 can be assembled with the vehicle's power battery. As some embodiments of this application, the first mounting member 947 can be constructed as a mounting post with a threaded hole. The vehicle's power battery has a through hole corresponding to the threaded hole. A bolt can be inserted into the through hole and mate with the threaded hole so that the first mounting member 947 can be assembled with the vehicle's power battery.

[0061] This configuration provides mounting points for the vehicle's power battery via the side crossbeam 9, improving the reliability of the power battery's fixation. Furthermore, it allows the power battery to be integrated into the overall vehicle structure, enhancing the vehicle's torsional resistance.

[0062] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, there are multiple first mounting members 947, at least a portion of the first mounting member 947 is housed in the second cavity 941, and the first mounting member 947 is connected to the fourth sub-base plate 946.

[0063] The number of first mounting members 947 can be multiple, including but not limited to two or three. In some embodiments of this application, the number of first mounting members 947 is two. Multiple first mounting members 947 can be arranged along a first direction (i.e.,...) Figure 1 The multiple first mounting members 947 can also be arranged in the second direction (i.e., the X direction shown). Figure 1 As shown in the Y direction, the multiple first mounting members 947 are arranged along the first direction (i.e., the Y direction). Figure 1 Multiple sets of first mounting components are arranged in the X direction (as shown) to form a first mounting component group, and multiple sets of first mounting component groups are arranged along the second direction (i.e., Figure 1 The Y-direction layout is shown.

[0064] At least a portion of the first mounting member 947 is housed in the second cavity 941, that is, a portion of the first mounting member 947 is housed in the second cavity 941, or the entire first mounting member 947 is housed in the second cavity 941. The first mounting member 947 is connected to the fourth sub-base plate 946. As some embodiments of this application, a portion of the first mounting member 947 is housed in the second cavity 941, and the first mounting member 947 can pass through and be connected to the fourth sub-base plate 946. As some embodiments of this application, the entire first mounting member 947 is housed in the second cavity 941, and the first mounting member 947 is connected to the fourth sub-base plate 946.

[0065] This arrangement allows for a more rational placement of the first mounting component 947, improving its structural strength and rigidity. This, in turn, enhances the connection stability between the side crossbeam 9 and the power battery connection point, reliably integrating the power battery into the overall vehicle structure and improving the vehicle's torsional rigidity. Furthermore, this arrangement allows for better alignment along a third direction (i.e.,...). Figure 1 The addition of a force transmission channel (as shown in the Z direction) is beneficial to improving the structural strength and force transmission performance of the side beam 9.

[0066] In some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 4As shown, the vehicle's side crossbeam 9 also includes: a first connecting plate 95, along a third direction (i.e. Figure 1 (As shown in the Z direction), the second top plate 943 is offset from the first top plate 923, and the first connecting plate 95 is connected between the first top plate 923 and the second top plate 943. The first top plate 923, the second top plate 943, and the first connecting plate 95 together define the expansion space 97. The third direction is perpendicular to both the first and second directions.

[0067] Among them, along the third direction (i.e. Figure 1 The second top plate 943 is offset from the first top plate 923 (as shown in the Z direction), that is, along the third direction (i.e. Figure 1 (As shown in the Z direction), the second top plate 943 and the first top plate 923 have different heights. A first connecting plate 95 connects the first top plate 923 and the second top plate 943. The connection method between the first connecting plate 95 and the first top plate 923 can be, but is not limited to, welding, bolting, etc. The connection method between the first connecting plate 95 and the second top plate 943 can be, but is not limited to, welding, bolting, etc. The first top plate 923, the second top plate 943, and the first connecting plate 95 together define an expansion space 97, which can be part of the crew compartment space. As some embodiments of this application, the first connecting plate 95, the first top plate 923, and the second top plate 943 are integrally formed.

[0068] The third direction (i.e.) Figure 1 The Z direction shown) and the first direction (i.e. Figure 1 The X direction shown), the second direction (i.e. Figure 1 The Y-direction shown is perpendicular to all other directions, meaning that the third direction (i.e., the Y-direction) is perpendicular to all other directions. Figure 1 The Z direction shown) and the first direction (i.e. Figure 1 The X directions shown are perpendicular to each other, and the third direction (i.e., Figure 1 The Z direction shown) and the second direction (i.e. Figure 1 The X directions shown are perpendicular to each other.

[0069] This arrangement allows for a reasonable structural design of the side crossbeam 9, improves the space utilization of the side crossbeam 9, and increases the space of the vehicle's passenger compartment, thereby enhancing the driving and riding experience.

[0070] In some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, the vehicle's side crossbeam 9 also includes: a second connecting plate 96, along a third direction (i.e. Figure 1 (as shown in the Z direction), the second top plate 943 is offset from the first top plate 923, and the second connecting plate 96 connects the first top plate 923 and the second top plate 943 along the first direction (i.e., Figure 1(as shown in the X direction), and from one end of the second connecting plate 96 to the other end, the distance between the second connecting plate 96 and the second base plate 944 gradually changes, and the third direction is perpendicular to both the first and second directions.

[0071] Among them, along the third direction (i.e. Figure 1 The second top plate 943 is offset from the first top plate 923 (as shown in the Z direction), that is, along the third direction (i.e. Figure 1 (As shown in the Z direction), the second top plate 943 and the first top plate 923 have different heights. A second connecting plate 96 connects the first top plate 923 and the second top plate 943. The connection method between the second connecting plate 96 and the first top plate 923 can be, but is not limited to, welding or bolting. The connection method between the second connecting plate 96 and the second top plate 943 can be, but is not limited to, welding or bolting. As some embodiments of this application, the second connecting plate 96, the first top plate 923, and the second top plate 943 are integrally formed.

[0072] As some embodiments of this application, along the first direction (i.e. Figure 1 (As shown in the X direction), the second connecting plate 96 has one end near the front of the vehicle and one end away from the front of the vehicle. From the end of the second connecting plate 96 near the front of the vehicle to the end away from the front of the vehicle, the distance between the second connecting plate 96 and the second base plate 944 gradually decreases.

[0073] The third direction (i.e.) Figure 1 The Z direction shown) and the first direction (i.e. Figure 1 The X direction shown), the second direction (i.e. Figure 1 The Y-direction shown is perpendicular to all other directions, meaning that the third direction (i.e., the Y-direction) is perpendicular to all other directions. Figure 1 The Z direction shown) and the first direction (i.e. Figure 1 The X directions shown are perpendicular to each other, and the third direction (i.e., Figure 1 The Z direction shown) and the second direction (i.e. Figure 1 The X directions shown are perpendicular to each other.

[0074] This configuration allows the side crossbeam 9 to smoothly transition the collision force, reducing the direct impact on the passenger compartment and lowering the probability of stress concentration in the side crossbeam 9. This facilitates the transmission, dispersion, and absorption of collision energy, thereby improving the vehicle's lateral stability.

[0075] In some embodiments of this utility model, such as Figure 2 As shown, the first sub-body 92 also includes a second mounting member 928, which is adapted to assemble with vehicle components.

[0076] As some embodiments of this application, the second mounting member 928 can be assembled with the vehicle's tower pack.
