It should be noted that the first transition plate 14, the middle channel connecting cross beam 12 and the second transition plate 15 form a mounting groove that matches the middle channel assembly 5. It still needs to be explained that the inclination directions of the first transition plate 14 and the second transition plate 15 in the present application are opposite. Specifically, the first transition plate 14 and the second transition plate 15 are symmetrically designed relative to the center of the middle channel connecting beam 12. In the present embodiment, the first transition plate 14 and the second transition plate 15 are designed to cooperate with the middle channel assembly 5. Therefore, the present application does not limit the inclination direction and inclination angle of the first transition plate 14 and the second transition plate 15.

[0029] The rear cross beam body 1 and the patch plate 2 of the present application are both integrated structures. The integrated structural design reduces the number of parts, reduces the connection welding points, and reduces the development of mold inspection fixtures, while saving costs and reducing investment; the integral structure reduces welding overlaps, which is conducive to lightweight design; and improves the strength of the front seat rear cross beam assembly composed of the rear cross beam body 1 and the patch plate 2.

[0030] See also Figure 1As shown in a specific example of the present application, the connection between the first transition plate 14 and the first rear cross beam 11 and the middle channel connecting cross beam 12 is an arc structure, and the connection between the second transition plate 15 and the second rear cross beam 13 and the middle channel connecting cross beam 12 is an arc structure. The arc structure design of the connection in this embodiment further improves the strength of the rear cross beam body 1 to ensure the safety of the driver.

[0031] See also Figure 1 As shown, in a specific example of the present application, a first connection portion 24 connected to the first transition plate 14 is provided between the first patch portion 21 and the second patch portion 22, and a second connection portion 25 connected to the second transition plate 15 is provided between the second patch portion 22 and the third patch portion 23. In this embodiment, the first transition plate 14 and the second transition plate 15 can improve the fit between the patch plate 2 and the rear cross beam body 1, and ensure the strength of the rear cross beam assembly formed by the combination of the rear cross beam body 1 and the patch plate 2.

[0032] See also Figure 1 As shown, in a specific example of the present application, the connection between the first connection portion 24 and the first patch portion 21 and the second patch portion 22 is an arc structure, and the connection between the second connection portion 25 and the second patch portion 22 and the third patch portion 23 is an arc structure. In this embodiment, the arc top structure on the patch plate 2 can cooperate with the arc structure on the rear cross beam body 1, further increasing the fit between the patch plate 2 and the rear cross beam body 1, ensuring the integrity of the front seat rear cross beam assembly, and further improving the strength of the front seat rear cross beam assembly to ensure the safety of the driver.

[0033] See also Figure 1 and Figure 2 As shown in a specific example of the present application, a weakening hole 111 is provided on the side of the first rear cross beam 11, and the weakening hole 111 is located in the area near the outer end of the first rear cross beam 11. In actual use, when impacted, the weakening hole 111 can guide the crushing position of the rear cross beam assembly of the front seat after the collision, ensuring that the collision crushing position is at the position required by the design, avoiding injury to the main driver.

[0034] See also Figure 1 and Figure 2 As shown, in a specific example of the present application, the outer side of the first patch portion 21 does not exceed the area on the first rear beam 11 where the weakening hole 111 is located. In this embodiment, the first patch portion 21 is located on the first rear beam 11, which ensures the strength of the first rear beam 11 after the first patch portion 21 cooperates with the first rear beam 11, and does not affect the weakening hole to guide the collision crushing, thereby reducing the damage caused by the collision to the main driver.

[0035] See also Figure 1 and Figure 3As shown, in a specific example of the present application, the third patch portion 23 is a structure extending a certain length toward the second rear beam 13 near the inner end of the second rear beam 13. Specifically, in this embodiment, the third patch portion 23 does not completely cover the second rear beam 13, reducing the number of welding points between the third patch portion 23 and the second rear beam 13; in this embodiment, each component between the patch plate 2 and the rear beam body 1 is connected, and the patch plate 2 can further increase the strength of the rear beam body 1; therefore, the matching of the patch plate 2 and the rear beam body 1 meets the performance design requirements while avoiding redundant design.

[0036] See also Figures 1 to 3 As shown, in a specific example of the present application, the outer end of the first rear cross beam 11 has a left threshold connection portion 112 for connecting to the left threshold assembly, and the outer end of the second rear cross beam 13 has a right threshold connection portion 131 for connecting to the right threshold assembly. Specifically, the left threshold connection portion 112 and the right threshold connection portion 131 each have two strip-shaped connection grooves, and in actual use, the positions where the front seat rear cross beam assembly is installed and fixed with the left threshold assembly and the right threshold assembly can be adjusted through the strip-shaped connection grooves.

[0037] In a specific example of the present application, the rear cross beam body 1 and the patch plate 2 are an integrated structure formed by stamping after welding. In this embodiment, the rear cross beam body 1 and the patch plate 2 are first welded and then stamped to form an integrated structure of the front seat rear cross beam assembly, which can be formed together with a set of molds, avoiding the investment of fixtures for welding after two sets of molds, reducing the investment cost of molds, inspection fixtures, and fixtures, while improving the strength of the front seat rear cross beam assembly and improving the safety performance of the car.

[0038] See also Figure 2 and Figure 3 As shown, a specific example of the present application is provided with four first mounting holes 121 on the middle channel connecting beam 12, and a second mounting hole 221 matching the first mounting hole 121 is provided on the second patch portion 22. In actual use, the auxiliary instrument panel is connected by passing the first mounting hole 121 and the second mounting hole 221 through the fixing bolt 8, so that the auxiliary instrument panel is connected to the front seat rear beam assembly; the first rear beam 11 and the second rear beam 13 are respectively provided with a first connecting hole 16. Since the patch plate 2 in this embodiment is not completely covered on the rear beam body 1, the patch plate 2 in this embodiment has a second connecting hole 26 matching the first several first connecting holes 16, and the connecting bolt 9 passes through the first connecting hole 16 and the second connecting hole 26 to install the front seat rear beam assembly on the vehicle floor. It should be noted that in this embodiment, the rear beam body 1 and the patch plate 2 are both made of thermoformed material, which can reduce the material thickness of the parts and is conducive to the lightweight design of the front seat rear beam assembly.
