Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a longitudinal beam assembly, a frame, and a vehicle. Background Technology

[0002] The subframe mounting component is used to connect the subframe. In the existing longitudinal beam assembly structure, the subframe mounting component is generally a shell with an open top, which is fastened to the bottom wall of the longitudinal beam, forming a cavity together with the longitudinal beam to construct a box-shaped force transmission structure.

[0003] Under complex stress conditions, such as sudden braking, bumps, and turns during vehicle operation, the subframe mounting components are prone to deformation, making the subframe's fixed state unstable. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a longitudinal beam assembly, a frame, and a vehicle that enhances the robustness of the first mounting component (subframe mounting component), thereby improving the reliability of the connection between the subframe and the longitudinal beam.

[0005] On one hand, this application provides a longitudinal beam assembly, which includes a longitudinal beam, a first mounting member, and reinforcing ribs. The first mounting member is connected to the longitudinal beam and has an included angle, and is used to connect to a subframe. The reinforcing ribs are disposed at the included angle and are connected to both the longitudinal beam and the first mounting member.

[0006] In one embodiment of this application, the longitudinal beam includes a beam body and a side plate. The side plate includes a first sub-section and a second sub-section, and the beam body is connected to the first sub-section. A first mounting member is connected to both the beam body and the second sub-section. The reinforcing rib, the first sub-section, and the second sub-section are integral structures.

[0007] In one embodiment of this application, the side plate is located on the outer side of the beam body and the first mounting member in the transverse direction.

[0008] In one embodiment of this application, the longitudinal beam assembly further includes a first reinforcing rib, which is disposed on the reinforcing rib and protrudes laterally relative to the reinforcing rib.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle, and the positive direction of the X-axis in the attached drawings is the forward direction; the left-right direction refers to the lateral direction of the vehicle, and the positive direction of the Y-axis in the attached drawings is the outward direction; the up-down direction refers to the vertical direction of the vehicle, and the positive direction of the Z-axis in the attached drawings is the upward direction.

[0031] The longitudinal beam assembly of this application is used in vehicles. Depending on its position in the vehicle, it can be a rear longitudinal beam assembly or a front longitudinal beam assembly. In the following embodiments, the rear longitudinal beam assembly is described as an example.

[0032] In the existing longitudinal beam assembly structure, the first mounting component, as a shell open on one side, connects to one side wall of the longitudinal beam, forming a cavity and constructing a box-shaped force transmission structure to fix the mounting sleeve. The subframe is bolted to the mounting sleeve, thus locking it to the longitudinal beam. The single-sided connection of the box-shaped force transmission structure leads to significant stress concentration at the connection point under load. When the subframe transmits load through the mounting sleeve, due to the limitations of the connection between the first mounting component and the longitudinal beam side wall, stress cannot be evenly distributed and concentrates at the connection point, causing excessive stress and making this area prone to deformation or even fracture, thus weakening the robustness of the first mounting component and the mounting sleeve. From the perspective of overall structural stability, the box-shaped force transmission structure lacks effective lateral support. Under complex stress conditions, such as lateral forces generated during vehicle movement (bumps, turns, etc.), the structure formed by the first mounting component and the longitudinal beam side wall is prone to lateral displacement or torsion, making the fixation of the first mounting component and the mounting sleeve unstable and further reducing its robustness.

[0033] In the following embodiments of this application, reinforcing ribs are provided to enhance the firmness of the first mounting component, thereby ensuring the reliability of the connection between the subframe and the longitudinal beam.

[0034] Please see Figures 1 to 3 . Figure 1 This is a front view of a longitudinal beam assembly according to an embodiment of this application. Figure 2 and Figure 3 They are Figure 1 The first and second viewpoints of the longitudinal beam assembly shown are three-dimensional structural schematic diagrams, showing only a portion of the structure.

[0035] This application provides a longitudinal beam assembly, which includes a longitudinal beam 10, a first mounting member 20, and a reinforcing rib 30. The first mounting member 20 is connected to the longitudinal beam 10 and has an included angle θ. The first mounting member 20 is used to connect to a subframe (not shown). The reinforcing rib 30 is disposed at the included angle θ and is connected to both the longitudinal beam 10 and the first mounting member 20.

[0036] The longitudinal beam 10 plays a crucial role in load-bearing and force transmission within the entire longitudinal beam assembly, and its design features a hollow structure. This hollow structure design effectively reduces its weight while ensuring structural strength, aligning with the lightweight design principles and requirements of modern vehicles. In terms of shape, the longitudinal beam 10 extends primarily in the longitudinal (X) direction, and its longitudinal X-direction coincides with the main force direction during vehicle operation, enabling it to better withstand and transmit the longitudinal X-load generated during vehicle travel, providing a stable support foundation for the overall vehicle structure.

[0037] The first mounting component 20, located below the longitudinal beam 10, connects the subframe within the longitudinal beam assembly. Specifically, its core function is to secure the mounting sleeve 40. The subframe, situated below the longitudinal beam 10, is bolted to the mounting sleeve 40 for a secure fastening. Structurally, the first mounting component 20 is shell-shaped, working in conjunction with the longitudinal beam 10 to form a second hollow structure, thus creating a box-shaped load-transfer structure. This box-shaped structure acts as a load-transfer bridge between the subframe and the longitudinal beam 10, and its structural performance directly impacts the reliability of the connection. During vehicle operation, all loads borne by the subframe are transmitted to the first mounting component 20 via the mounting sleeve 40, and then from the first mounting component 20 to the longitudinal beam 10. Therefore, the structural strength and stability of the first mounting component 20 directly affect the reliability of the connection between the subframe and the longitudinal beam 10.

[0038] A portion of the first mounting member 20 and a portion of the longitudinal beam 10 are inclined relative to each other at the connection point, thus forming an included angle θ. This included angle θ can be an obtuse angle, a right angle, or an acute angle. Figure 2 As shown, the longitudinal beam 10 has a bottom wall 150. The first mounting member 20 has a side wall 250 located on one side in the longitudinal direction X. The bottom wall 150 and the side wall 250 are arranged at an angle relative to each other to form an included angle θ.

[0039] The reinforcing rib 30 is positioned at the angle θ formed by the first mounting member 20 and the longitudinal beam 10, and is connected to both the longitudinal beam 10 and the first mounting member 20. This connection method allows the reinforcing rib 30 to effectively participate in the load-bearing system of the entire structure, enhancing the overall performance of the structure.

[0040] The reinforcing ribs 30 are located outside the first hollow structure and the second hollow structure, respectively. In some other embodiments, the reinforcing ribs 30 may also be disposed inside the second hollow structure.

[0041] Regarding the quantity configuration, there can be one or more stiffening ribs 30. The specific number to choose needs to comprehensively consider factors such as the magnitude and distribution of the stress on the structure, as well as cost. When the structure bears a large and complex load, setting multiple stiffening ribs 30 can more effectively disperse stress and enhance the stability of the structure; while when the load is relatively small and the structure is relatively simple, one stiffening rib 30 may be sufficient to meet the performance requirements, thus reducing manufacturing costs while ensuring structural performance.

[0042] During actual vehicle operation, the external forces acting on the first mounting component 20 are highly complex and can be decomposed into components in multiple directions. When the reinforcing ribs 30 connect the longitudinal beam 10 and the first mounting component 20, the stress generated by the external forces acting on the first mounting component 20 is dispersed through the connection points between the reinforcing ribs 30 and the first mounting component 20 and the longitudinal beam 10, via an oblique force transmission path. Compared to the original structure, this stress dispersion method results in a more uniform stress distribution, effectively avoiding localized stress concentration in the first mounting component 20.

[0043] The reinforcing rib 30 also significantly enhances the rigidity of the first mounting member 20. When the first mounting member 20 is subjected to external force and attempts to deform, the reinforcing rib 30 constrains its deformation. During the deformation process of the first mounting member 20 under stress, an interaction force is generated between the reinforcing rib 30 and the first mounting member 20, thereby reducing the strain within the first mounting member 20, lowering the risk of material failure due to excessive deformation, and further ensuring the structural stability and reliability of the first mounting member 20.

[0044] During long-term vehicle use, frequent vibrations and complex operating conditions can cause fatigue damage to components. The introduction of reinforcing ribs 30 effectively enhances the stability of the overall structure, slows down the fatigue process of the first mounting component 20 and the longitudinal beam 10, thereby extending the service life of the longitudinal beam assembly. In extreme conditions such as vehicle collisions, reinforcing ribs 30 can more effectively disperse the impact force to the longitudinal beam 10, reducing the probability of the first mounting component 20 failing due to excessive instantaneous impact force.

[0045] In summary, this application enhances the robustness of the first mounting component 20 and improves the reliability of the connection between the subframe and the longitudinal beam 10 by rationally setting the reinforcing ribs 30.

[0046] In some embodiments, the reinforcing rib 30 and the longitudinal beam 10 are an integral structure. For example, the reinforcing rib 30 is directly formed at the same time as the longitudinal beam 10 is manufactured by processes such as stamping, casting or forging. This integral structure can ensure good mechanical property transfer between the reinforcing rib 30 and the longitudinal beam 10, reduce stress concentration at the connection parts, and improve the overall structural strength.

[0047] Specifically, "integrated structure" and "split structure" are two contrasting concepts. An "integrated structure" refers to an object that is a continuous, indivisible whole, without obvious assembly interfaces or detachable parts. Its components are tightly connected, forming a unified structure. A "split structure," on the other hand, refers to an object composed of multiple independent parts, assembled together using specific connection methods (such as bolts, nuts, tenons, etc.) to form a complete object. Each component can be an independent entity before assembly, possessing a relatively independent shape and function.

[0048] In other embodiments, the reinforcing rib 30 is an integral structure with the first mounting member 20, so that it can better adapt to the stress characteristics of the first mounting member 20 and enhance the local strength and rigidity of the first mounting member 20.

[0049] In other embodiments, the reinforcing rib 30 is a separate structure from the longitudinal beam 10 and the first mounting component 20, respectively, and is fixed to the longitudinal beam 10 and the first mounting component 20 by welding, bolting, or other methods. The separate structure design provides a certain degree of flexibility in manufacturing and installation, facilitating adjustment and replacement according to actual needs.

[0050] exist Figure 1 In the embodiment shown, the reinforcing rib 30 and the longitudinal beam 10 are an integral structure, which will be described in detail below.

[0051] Please see Figure 4 and Figure 5 . Figure 4 yes Figure 1 The diagram shows a three-dimensional exploded view of the longitudinal beam assembly. Figure 5 yes Figure 1 Cross-sectional view at E1-E1.

[0052] In some embodiments, the longitudinal beam 10 includes a beam body 140 and a side plate 130, the side plate 130 including a first sub-part 131 and a second sub-part 132. The beam body 140 is connected to the first sub-part 131. A first mounting member 20 is connected to the beam body 140 and the second sub-part 132 respectively. The reinforcing rib 30, the first sub-part 131 and the second sub-part 132 are integral structures.

[0053] The first sub-part 131 and the main beam 140 enclose a first cavity 910. The first cavity 910 generally extends in the longitudinal direction X. The second sub-part 132 is located below the first sub-part 131 in the vertical direction Z. The second sub-part 132 protrudes from the main beam 140.

[0054] The first mounting component 20 is positioned below the beam body 140 along the vertical Z direction. The first mounting component 20, together with the beam body 140 and the second sub-component 132, forms the second cavity 920. The aforementioned bottom wall 150 is located within the beam body 140.

[0055] The first mounting component 20 has an angle θ with the main beam 140. The reinforcing ribs 30 are provided on the vertical Z side of the first sub-part 131 and on the longitudinal X side of the second sub-part 132.

[0056] In an assembly scenario, a beam body 140, a side plate 130, and a first mounting component 20 are first provided. Then, the beam body 140 and the first sub-part 131 of the side plate 130 are connected to form a first hollow structure. Next, the first mounting component 20 is connected to both the beam body 140 and the second sub-part 132 to form a second hollow structure. Since the reinforcing rib 30, the first sub-part 131, and the second sub-part 132 are an integral structure, the reinforcing rib 30 is now connected to both the longitudinal beam 10 and the first mounting component 20.

[0057] Furthermore, the side plate 130 is located on the outer side of the beam body 140 and the first mounting member 20 in the transverse Y direction.

[0058] Specifically, the main beam 140 includes an upper plate 110 and a lower plate 120. The upper plate 110 and the lower plate 120 are joined vertically in the Z direction to form a groove structure. The groove opening of the groove structure is open outward in the Y direction. The side plate 130 is joined to the upper plate 110 and the lower plate 120 in the Y direction to seal the groove opening, thereby jointly enclosing and forming a first cavity 910. The upper plate 110, the lower plate 120, and the side plate 130 can be welded together.

[0059] Specifically, the first mounting member 20 is disposed below the lower plate 120. The first mounting member 20 is disposed inside the second sub-part 132 in the transverse Y direction. The first mounting member 20 is aligned with the lower plate 120 in the vertical Z direction. The first mounting member 20 is aligned with the second sub-part 132 in the transverse Y direction. The first mounting member 20, the lower plate 120, and the second sub-part 132 together form a second cavity 920. The first mounting member 20 and the lower plate 120 have an included angle θ. The bottom wall 150 is located on the lower plate 120. The first mounting member 20, the lower plate 120, and the second sub-part 132 can be welded together.

[0060] When a vehicle experiences a transverse Y-axis impact from the outside in, the side panel 130 is the first to bear the impact force. Due to its outer position in the transverse Y-axis, the side panel 130 can directly contact and absorb the impact energy. The impact force borne by the side panel 130 is not concentrated at a single point, but is dispersed along its structural path. The side panel 130 transmits a portion of the force to the first mounting member 20, and another portion to the beam body 140. The beam body 140, with its groove structure and the design of the first cavity 910, can further disperse the incoming impact force longitudinally X, gradually dissipating the energy. This dispersion mechanism effectively reduces the instantaneous impact load borne by the first mounting member 20. Compared to traditional structures, the first mounting member 20 no longer directly bears the enormous impact force, but instead, through the synergistic effect of the side panel 130 and the beam body 140, transforms the impact force into a more uniform stress distribution. Taking a real-world collision scenario as an example, in a side collision, without the effective dispersion of the side plate 130, the first mounting component 20 may deform or even break due to excessive instantaneous impact, leading to the failure of the connection between the subframe and the longitudinal beam 10. However, in this technical solution, after the side plate 130 disperses the impact force, the stress borne by the first mounting component 20 is far below its ultimate strength, effectively preventing structural damage, enhancing the robustness of the first mounting component 20, and thus improving the reliability of the connection between the subframe and the longitudinal beam 10.

[0061] Please see Figure 3 and Figure 4 In some implementations, the longitudinal beam assembly also includes a first reinforcing rib 90, which is disposed on the reinforcing rib 30 and protrudes in the transverse Y direction relative to the reinforcing rib 30.

[0062] Specifically, the reinforcing rib 30 is generally flat and perpendicular to the transverse Y-shape. The reinforcing rib 30 has an outer surface and an inner surface that are opposite to each other in the transverse Y-shape. A first reinforcing rib 90 is formed as a protrusion on the outer surface of the reinforcing rib 30 and as a recess on the inner surface of the reinforcing rib 30. In some embodiments, the first reinforcing rib 90 can be formed on the reinforcing rib 30 by stamping.

[0063] In this embodiment, by setting the first reinforcing rib 90, the structural strength and rigidity of the reinforcing rib 30 can be improved, enabling the reinforcing rib 30 to more effectively resist deformation when facing various complex external forces, thereby enhancing the firmness of the first mounting component 20. For example, during vehicle operation, irregular impact forces generated by road bumps and lateral forces during turning can be effectively dispersed and absorbed through the synergistic effect of the first reinforcing rib 90 and the reinforcing rib 30.

[0064] In some other embodiments, the first reinforcing rib 90 adopts a mesh-like structure. The first reinforcing rib 90 constructs a mesh-like structure on the surface of the reinforcing rib 30 through crisscrossing ribs. This structure can be integrally formed using a casting process. During the forming of the reinforcing rib 30, the molten metal is filled to form the mesh-like ribs through mold design. The mesh-like layout can provide support for the reinforcing rib 30 in multiple directions. Whether external forces are applied laterally (Y), longitudinally (X), or diagonally, the stress can be distributed across the entire surface of the reinforcing rib 30 through the intersections of the mesh.

[0065] In some other embodiments, the first reinforcing rib 90 adopts a honeycomb structure. The first reinforcing rib 90 is based on hexagonal or other polygonal honeycomb cells, arranged on the surface of the reinforcing rib 30 to form a honeycomb structure. It can be precisely manufactured using 3D printing technology, constructing a complex honeycomb structure by layer-by-layer material deposition. When subjected to external forces, the honeycomb cells support each other, evenly distributing the load across the cell walls and effectively preventing localized overload.

[0066] In addition to the examples mentioned above, the first reinforcing rib 90 can also adopt other structural forms.

[0067] Please see Figure 4 and Figure 5 In some embodiments, the longitudinal beam assembly further includes a mounting sleeve 40 and a reinforcement 60. The mounting sleeve 40 is used to connect to the subframe. The reinforcement 60 is clamped between the mounting sleeve 40 and the first mounting member 20 in the axial direction of the mounting sleeve 40.

[0068] The mounting sleeve 40 has an internally threaded hole 410, the axis of which is parallel to the vertical Z direction. The longitudinal beam 10 has a first through hole 121, which connects to the first cavity 910 and the second cavity 920. The mounting sleeve 40 passes through the first through hole 121. The top end of the mounting sleeve 40 is located in the first cavity 910, and the bottom end is located in the second cavity 920.

[0069] The first mounting component 20 has a third through hole 210, which is positioned opposite to the internal threaded hole 410.

[0070] The reinforcing member 60 is located within the second cavity 920 and is connected to both the mounting sleeve 40 and the first mounting member 20. In some embodiments, with the axial direction of the mounting sleeve 40 as the projection direction, the projection of the mounting sleeve 40 lies within the projection of the reinforcing member 60. In the radial direction of the mounting sleeve 40, the reinforcing member 60 is larger than the mounting sleeve 40, thereby enhancing the connection strength between the mounting sleeve 40 and the first mounting member 20.

[0071] The reinforcing member 60 has a fourth through hole 610, which is positioned opposite to the internal threaded hole 410.

[0072] When assembling the subframe, bolts (not shown) that are compatible with the internal threaded hole 410 pass through the third through hole 210 and the fourth through hole 610 in sequence, and engage with the mounting sleeve 40 through the internal threaded hole 410, thereby locking the subframe to the longitudinal beam 10.

[0073] In this embodiment, by providing the reinforcing member 60, the connection strength between the mounting sleeve 40 and the first mounting member 20 is enhanced, the firmness of the mounting sleeve 40 is improved, and the reliability of the connection between the subframe and the longitudinal beam 10 is improved.

[0074] Please see Figure 4 and Figure 5 In some embodiments, the longitudinal beam 10 has a first through hole 121 and a second through hole 122, the second through hole 122 being disposed adjacent to the first through hole 121, and the mounting sleeve 40 passing through the first through hole 121.

[0075] The second through hole 122 is configured to allow observation of the connection between the mounting sleeve 40 and the reinforcing member 60 from one side of the first cavity 910.

[0076] Because the mounting sleeve 40 is quite thick, in some embodiments, the mounting sleeve 40 and the reinforcing member 60 are connected by manual welding. To avoid oversights, visual inspection is required during assembly. In one inspection scenario, inspectors check for defects at the connection between the mounting sleeve 40 and the reinforcing member 60 through the second through hole 122; alternatively, visual inspection equipment checks for defects at the connection between the mounting sleeve 40 and the reinforcing member 60 through the second through hole 122.

[0077] In some embodiments, there is a gap between the edge of the first through hole 121 and the mounting sleeve 40, through which the connection between the mounting sleeve 40 and the reinforcement 60 can be inspected.

[0078] Please see Figure 6 and Figure 7 . Figure 6 yes Figure 1 A three-dimensional structural schematic diagram of the bracket 70 in the longitudinal beam assembly shown. Figure 7 yes Figure 1 Sectional view at E1-E1.

[0079] In some embodiments, the longitudinal beam assembly further includes a bracket 70 connected to the longitudinal beam 10, the bracket 70 including a second reinforcing rib 720 connected to the mounting sleeve 40, and / or the bracket 70 folds to one side at its vertically Z-extending edge to form a third reinforcing rib 750.

[0080] Here, "and / or" specifically means: in some embodiments, the bracket 70 includes a second reinforcing rib 720, which is connected to the mounting sleeve 40; in some embodiments, the bracket 70 is folded to one side at its vertically Z-extending edge to form a third reinforcing rib 750; in some embodiments, the bracket 70 includes a second reinforcing rib 720, which is connected to the mounting sleeve 40, and the bracket 70 is folded to one side at its vertically Z-extending edge to form a third reinforcing rib 750.

[0081] Specifically, the support 70 is housed within the first cavity 910. The support 70 includes a substrate 710, a first flange 730, and a second flange 740. The substrate 710 is generally flat. The substrate 710 has a first edge 711, a second edge 712, a third edge 713, and a fourth edge 714 connected end-to-end. The first edge 711 is located at the top end. The third edge 713 is located at the bottom end. The second edge 712 connects the first edge 711 and the third edge 713. The second edge 712 and the first edge 711 are connected by an arcuate transition. The fourth edge 714 connects the first edge 711 and the third edge 713. The second edge 712 and the fourth edge 714 are located on opposite sides of the substrate 710. The first flange 730 is connected to the first edge 711 and the second edge 712. The second flange 740 is connected to the third edge 713. The first flange 730 and the second flange 740 are respectively inclined relative to the substrate 710. The first flange 730 is respectively attached to the inner wall surfaces of the upper plate 110 and the lower plate 120, and is connected to the upper plate 110 and the lower plate 120 respectively. The second flange 740 is attached to the inner wall surface of the lower plate 120 and is connected to the lower plate 120. This arrangement increases the contact area, thereby improving the connection strength between the bracket 70 and the longitudinal beam 10, and further enhancing the firmness of the mounting sleeve 40. In some embodiments, the substrate 710, the first flange 730 and the second flange 740 are integrally formed by a stamping process. In some embodiments, a notch 770 is provided on the edge of the first flange 730 away from the substrate 710 to prevent the first flange 730 from cracking during the stamping process. In some embodiments, anti-rebound ribs 760 are respectively provided at the first edge 711 and the third edge 713 to stabilize the included angle between the first flange 730 and the substrate 710, and to stabilize the included angle between the second flange 740 and the substrate 710.

[0082] The second reinforcing rib 720 is formed on the substrate 710, protruding from one side of the substrate 710 and recessed from the opposite side. In one manufacturing scenario, the substrate 710 and the second reinforcing rib 720 are integrally formed by a stamping process. The second reinforcing rib 720 has an end face 721 on the side facing away from the substrate 710 in the protruding direction, which abuts against and connects to the mounting sleeve 40. In some embodiments, the mounting sleeve 40 and the second reinforcing rib 720 are welded together at the joint. By providing the second reinforcing rib 720, the structural strength and rigidity of the bracket 70 can be enhanced. By abutting against and connecting the second reinforcing rib 720 to the mounting sleeve 40, the protrusion height of the second reinforcing rib 720 can be easily adjusted by the stamping process, thereby facilitating the adjustment of the position of the mounting sleeve 40.

[0083] The fourth edge 714 is the edge of the support 70 extending vertically in the Z direction. At the fourth edge 714, the support 70 is folded to one side to form a third reinforcing rib 750. In one manufacturing scenario, the third reinforcing rib 750 is formed by a stamping process. The third reinforcing rib 750 can enhance the structural strength of the support 70 in the vertical Z direction.

[0084] Please see Figure 8 . Figure 8 yes Figure 1 The top view of the longitudinal beam assembly shown.

[0085] In some embodiments, the longitudinal beam assembly further includes a second mounting member 50, one end of which is clamped between the first mounting member 20 and the longitudinal beam 10, and the other end of which is used to connect to the crossbeam 80.

[0086] Specifically, one end of the second mounting member 50 is clamped between the first mounting member 20 and the longitudinal beam 10 in the vertical Z direction, and is connected to both the first mounting member 20 and the longitudinal beam 10. The other end of the second mounting member 50 extends inward in the transverse Y direction. The crossbeam 80 is supported by the other end of the second mounting member 50 and is connected to the second mounting member 50.

[0087] The first mounting member 20 and the second mounting member 50 are positioned at the same location, working together to enhance their connection strength with the longitudinal beam 10. During vehicle operation, the longitudinal beam assembly bears complex loads from different directions. When the first mounting member 20 and the second mounting member 50 work together, these loads can be distributed more efficiently. Taking longitudinal X-load as an example, the force transmitted from the subframe to the longitudinal beam 10 through the first mounting member 20 no longer relies solely on the single connection path between the first mounting member 20 and the longitudinal beam 10. The second mounting member 50, sandwiched between the first mounting member 20 and the longitudinal beam 10, effectively adds another load transmission channel. The second mounting member 50 can share some of the longitudinal X-force and transmit it along its own structure to different parts of the longitudinal beam 10, thus dispersing the stress originally concentrated at the connection point between the first mounting member 20 and the longitudinal beam 10.

[0088] The following reference Figure 9 introduce Figure 1 The assembly process of the longitudinal beam assembly is shown.

[0089] In an assembly scenario, the assembly process of the longitudinal beam assembly includes the following steps.

[0090] The system provides a first component 1, a second component 2, and a third component 3. The first component 1 includes an assembled upper plate 110, a lower plate 120, and a bracket 70. The second component 2 includes an assembled first mounting component 20, a second mounting component 50, a reinforcing component 60, and a mounting sleeve 40. The third component 3 includes a side plate 130 and reinforcing ribs 30 integrally formed with the side plate 130.

[0091] Connect the second component 2 to the first component 1. Specifically, insert the top end of the mounting sleeve 40 into the cavity formed by the upper plate 110 and the lower plate 120 through the first through hole 121. Connect the mounting sleeve 40 to the bracket 70. Connect the first mounting member 20 and the second mounting member 50 to the lower plate 120 respectively.

[0092] The third component 3 is connected to the first component 1 and the second component 2 respectively. Specifically, the side plate 130 is connected to the upper plate 110 and the lower plate 120 in the transverse Y direction, and at the same time, the side plate 130 is connected to the first mounting member 20 in the transverse Y direction.
