[0011] The side beam support ribs and / or support beam support ribs are in a "T" shape.

[0012] Furthermore, a cavity located between the side beam mounting portion and the support beam mounting portion is provided on the side beam connecting member, and a reinforcing rib connected between the side beam mounting portion and the support beam mounting portion is provided in the cavity.

[0013] Furthermore, the reinforcing ribs include longitudinal ribs connected between the side beam mounting portion and the support beam mounting portion, and transverse ribs interwoven with the longitudinal ribs;

[0014] The longitudinal ribs are multiple and are arranged at intervals along the extending direction of the transverse ribs, and each of the longitudinal ribs is arranged in a rearward arch in the front-rear direction of the vehicle.

[0015] Furthermore, the wheel house side beam and the support beam, as well as the wheel house side beam, the support beam and the side beam connecting piece are connected by a riveted structure;

[0016] At least two side surfaces of the wheel arch side beam are connected to the side beam connecting member via the riveted structure, and / or at least two side surfaces of the support beam are connected to the side beam connecting member via the riveted structure.

[0017] Furthermore, the wheel house side beam and the support beam are respectively provided with collapse holes;

[0018] The collapse holes on the wheel arch side beam and the support beam are both arranged close to the side beam connecting member, and the collapse holes on the wheel arch side beam and the support beam are multiple and arranged side by side.

[0019] Further, the wheel house side beam and the support beam are formed by extrusion of aluminum alloy, and the side beam connecting piece is formed by casting of aluminum alloy; and / or,

[0020] A mounting boss is provided on one side of the wheel house side beam, the mounting boss is arranged close to the front end of the wheel house side beam, and the mounting boss is integrally formed on the wheel house side beam.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] The wheel arch side beam assembly described in the present invention is formed by extruding the wheel arch side beam and the supporting beam and casting the side beam connecting parts. Therefore, the development cycle of the entire front wheel arch side beam is short, the mold investment is low, the production line investment is low, which is conducive to reducing production costs, and the force transmission is continuous, and the collision force transmission and energy absorption effects are good, which is conducive to improving the collision safety of the entire vehicle.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0045] Embodiment 1

[0046] This embodiment relates to a front wheel housing side beam assembly, the overall structure of which is as follows: Figure 1 As shown in , the front wheel house side beam assembly includes a wheel house side beam 1, a side beam connector 3 located at the rear side of the wheel house side beam 1, and a support beam 2 provided between the wheel house side beam 1 and the side beam connector 3. The rear end of the wheel house side beam 1 is connected to the side beam connector 3, one end of the support beam 2 is connected to the wheel house side beam 1, and the other end of the support beam 2 is connected to the side beam connector 3, and the wheel house side beam 1 and the support beam 2 are extruded, and the side beam connector 3 is cast.

[0047] By extruding the wheel arch side beam 1 and the support beam 2 and casting the side beam connector 3, the development cycle of the entire front wheel arch side beam assembly is short, the mold investment is low, and the production line investment is low, which is conducive to reducing production costs. In addition, the wheel arch side beam 1 and the support beam 2 are easy to crush, and the deformation and crushing are stable, which is conducive to converting the collision kinetic energy into deformation energy and fully absorbing the collision energy.

[0048] In addition, the side beam connector 3 has high rigidity and is not easily deformed. It can properly participate in collision energy absorption and evenly transfer the collision energy to the lower section of the A-pillar to avoid the concentration of force on the upper section of the A-pillar, which causes the A-pillar to bend and deform, threatening the safety of the occupants. Overall, the front wheel cover side beam assembly has a coherent force transmission, good collision force transmission and energy absorption effects, and is conducive to improving the collision safety of the entire vehicle.

[0049] Based on the above overall introduction, as a preferred implementation method, Figure 2 As shown in FIG. 1 , in this embodiment, the support beam 2 is located below the wheel house side beam 1, and the support beam 2 is arranged obliquely relative to the wheel house side beam 1. The wheel house side beam 1, the support beam 2 and the side beam connector 3 are connected to form a triangular structure. In this way, the high strength of the triangular structure can be utilized to ensure the overall rigidity of the wheel house side beam 1 and the collision force transmission performance.

[0050] As a preferred example, Figure 2 and Figure 6 As shown in , in this embodiment, the side beam connector 3 has a side beam mounting portion and a support beam mounting portion, and a side beam mounting groove 4 is provided at the side beam mounting portion, and a support beam mounting groove 5 is provided at the support beam mounting portion. The side beam mounting groove 4 and the support beam mounting groove 5 are both open at the front side of the side beam connector 3, and the rear end of the wheel house side beam 1 is inserted into the side beam mounting groove 4, and the rear end of the support beam 2 is inserted into the support beam mounting groove 5. By inserting the wheel house side beam 1 into the side beam mounting groove 4 and the support beam 2 into the support beam mounting groove 5, the connection between the wheel house side beam 1 and the support beam 2 and the side beam connector 3 is facilitated, and the stability of the connection can be ensured.

[0051] As a preferred implementation, in this embodiment, a side beam support rib 6 capable of supporting the rear end of the wheel house side beam 1 is provided in the side beam installation groove 4, and a support beam support rib 7 capable of supporting the rear end of the support beam 2 is provided in the support beam installation groove 5, and the side beam support rib 6 and the support beam support rib 7 are in a "T" shape. Figure 6 As shown in , the side beam support member includes a first portion 601 supported at the end of the rear wheel housing side beam 1, and a second portion 602 arranged perpendicularly to the first portion 601. The support beam support rib 7 includes a third portion 701 supported at the end of the support beam 2, and a fourth portion 702 arranged perpendicularly to the third portion 701.

[0052] It is understandable that by providing the side beam support ribs 6 and the support beam support ribs 7, and making the side beam support ribs 6 and the support beam support ribs 7 both in a "T" shape, it is beneficial to improve the support of the wheel arch side beam 1 and the support beam 2 during the force transmission process, and ensure the continuity and stability of the force transmission. Of course, in this embodiment, making the side beam support ribs 6 and the support beam support ribs 7 in a "T" shape is only a preferred implementation method. In addition, it is also possible to choose to set only the side beam support ribs 6 or only the support beam support ribs 7 in a T shape.

[0053] As a preferred implementation method, Figure 1 and Figure 7As shown in , in this embodiment, a cavity 8 located between the side beam mounting portion and the support beam mounting portion is provided on the side beam connector 3, and a reinforcing rib 9 connected between the side beam mounting portion and the support beam mounting portion is provided in the cavity 8. By providing the cavity 8 and the reinforcing rib 9 in the cavity 8, the structural strength of the connector can be ensured while facilitating the weight reduction of the side beam connector 3, and the transmission effect of the collision force can be ensured.

[0054] Specifically, Figure 7 As shown in , the reinforcing rib 9 includes a longitudinal rib 901 connected between the side beam mounting portion and the support beam mounting portion, and a transverse rib 902 interlaced with the longitudinal rib 901. The longitudinal ribs 901 are arranged in a plurality of intervals along the extending direction of the transverse rib 902, and each longitudinal rib 901 is arranged in the rear arch in the front-rear direction of the vehicle.

[0055] By making the reinforcing rib 9 include a longitudinal rib 901 and a transverse rib 902, and arranging the longitudinal rib 901 in a rear arch in the front-rear direction of the vehicle, the structural strength of the side beam connector 3 can be ensured while enhancing the force transmission continuity and stability of the side beam connector 3, thereby avoiding the side beam connector 3 from tearing in the direction of the angle between the wheel arch side beam 1 and the support beam 2 during the force transmission process, and being able to evenly transmit the collision force to the overlapping area at the rear of the side beam connector 3.

[0056] As a preferred embodiment, Figure 1 and Figure 2 As shown in the figure, in this embodiment, the wheel house side beam 1 and the support beam 2, as well as the wheel house side beam 1, the support beam 2 and the side beam connector 3 are connected by a riveted structure. The two side surfaces of the wheel house side beam 1 are connected to the side beam connector 3 by a riveted structure, and the two side surfaces of the support beam 2 are connected to the side beam connector 3 by a riveted structure.

[0057] It can be understood that by connecting the wheel house side beam 1 and the support beam 2, and the wheel house side beam 1, the support beam 2 and the side beam connector 3 with a riveted structure, the connection method is simple and the connection operation is convenient. In a specific implementation, the wheel house side beam 1 and the support beam 2, and the wheel house side beam 1, the support beam 2 and the side beam connector 3 can be connected by a blind rivet 11 commonly used in the prior art.

[0058] In addition, if Figure 1 and Figure 2 As shown in the figure, in this embodiment, the top and side surfaces of the wheel arch side beam 1 are riveted to the side beam connector 3, and the bottom and side surfaces of the support beam 2 are riveted to the side beam connector 3.

[0059] By making the wheel house side beam 1 and the support beam 2 both have two side surfaces connected to the side beam connector 3 through a riveted structure, the connection reliability can be ensured and the force transmission stability can be improved. Of course, in this embodiment, making the wheel house side beam 1 and the support beam 2 both have two side surfaces connected to the side beam through a riveted structure is only a preferred implementation method. In addition, more side surfaces of the wheel house side beam 1 or the support beam 2 can also be connected to the side beam support member through a riveted structure, such as three, four, and five.

[0060] In addition, if Figure 4 and Figure 5 As shown in , in this embodiment, a first installation gap 13 is reserved between the bottom surface of the wheel house side beam 1 and the side beam connector 3 to facilitate the assembly of the wheel house side beam 1 and the side beam connector 3. A second installation gap 14 is reserved between the top surface of the support beam 2 and the side beam connector 3 to facilitate the assembly of the support beam 2 and the side beam connector 3. In specific implementation, the width of the first installation gap 13 and the second installation gap 14 can be greater than or equal to 3 mm, specifically 3 mm, 4 mm, 5 mm, 6 mm, etc.

[0061] As a preferred embodiment, Figure 1 and Figure 2 and Figure 8 As shown in , in this embodiment, collapse holes 10 are respectively provided on the wheel house side beam 1 and the support beam 2. The collapse holes 10 on the wheel house side beam 1 and the support beam 2 are both arranged close to the side beam connector 3, and the collapse holes 10 on the wheel house side beam 1 and the support beam 2 are both arranged side by side. Such an arrangement can ensure that the actual deformation mode of the wheel house side beam 1 and the support beam 2 inducing the crushing deformation during the force transmission process is consistent with the theoretical design, so that the crushing deformation and energy absorption are more controllable.

[0062] In addition, as a preferred embodiment, the wheel arch side beam 1 and the support beam 2 are formed by extrusion of aluminum alloy, and the side beam connector 3 is formed by casting of aluminum alloy. A mounting boss 12 is provided on one side of the wheel arch side beam 1, and the mounting boss 12 is arranged near the front end of the wheel arch side beam 1, and the mounting boss 12 is integrally formed on the wheel arch side beam 1.

[0063] By making the wheel house side beam 1 and the support beam 2 extruded from aluminum alloy, and the side beam connector 3 die-cast from aluminum alloy, it is easy to form and is conducive to lightweight design. In this embodiment, the installation boss 12 is provided to facilitate the connection between the wheel house side beam 1 and the surrounding parts in the cabin, and to facilitate the installation of accessories in the cabin.

[0064] Of course, in this embodiment, the wheel house side beam 1, the support beam 2 and the side beam connector 3 are made of aluminum alloy, which is only a preferred embodiment. In addition, other materials can be selected to ensure that the strength and rigidity requirements of the front wheel house side beam assembly are met. In addition, the installation boss 12 is also only a preferred embodiment. In other embodiments, the installation boss 12 can also be selected not to be provided.

[0065] The front wheel arch side beam assembly of this embodiment is formed by extruding the wheel arch side beam 1 and the support beam 2 and casting the side beam connector 3. The development cycle of the entire front wheel arch side beam assembly is short, the mold investment is low, the production line investment is low, which is conducive to reducing production costs, and the force transmission is continuous, and the collision force transmission and energy absorption effects are good, which is conducive to improving the collision safety of the entire vehicle.
