[0030] like Figure 1-Figure 7 As shown, the utility model provides a seat cross beam.

[0031] In an exemplary embodiment, the seat crossbar comprises:

[0032] A crossbeam body 1, used to be connected to the vehicle body and the seat respectively;

[0033] The support assembly is arranged on the cross beam body 1 and is used to abut against the vehicle body to support the cross beam body 1 so as to form a buffer gap between the cross beam body 1 and the vehicle body.

[0034] In this embodiment, the seat crossbeam installed in the vehicle body can be supported by the provided support assembly. When the vehicle is subjected to a side collision, the force applied to the crossbeam body 1 can be diffused through the support assembly. At the same time, due to the provided support assembly, a buffer gap is formed between the crossbeam body 1 and the vehicle body, which buffers the force applied to the crossbeam, thereby improving the overall force-bearing performance of the crossbeam body 1, enhancing its rigidity, and strengthening its side collision performance.

[0035] It is worth mentioning that Figure 7As shown in the figure, the crossbeam body 1 in this embodiment adopts a rolling process and is welded by two laser welds to form two closed "mouth" - shaped cavity structures. The crossbeam body 1, the vehicle body floor panel and the sill beam form an inverted "pin" - shaped closed loop cavity structure, which has good integrity and greatly improves the rigidity and side - impact performance of the seat crossbeam assembly. The crossbeam body 1 presents an inverted "8" - shaped cross - section feature, which not only effectively improves the rigidity and side - impact performance of the crossbeam body 1, but also has a simple process and good integrity. Moreover, it effectively avoids the complex welding process of multiple stamping thin - wall parts after forming, and has higher precision.

[0036] In an exemplary embodiment, the crossbeam body 1 includes a first side surface 101, a second side surface 102, a third side surface 103 and a fourth side surface 104 arranged in sequence around its axis. The fourth side surface 104 is used to connect with the vehicle body, and the second side surface 102 is used to connect with the seat. Among them, the support assembly is installed on the first side surface 101 and the third side surface 103 or installed on the fourth side surface 104.

[0037] In this embodiment, the cross - section of the crossbeam body 1 is as Figure 7 shown. Its overall structure is a cuboid, including four side surfaces. Among them, the first side surface 101 and the third side surface 103 are respectively the side surfaces (left and right side walls) of the crossbeam body 1 in the width direction, and the second side surface 102 and the fourth side surface 104 are respectively the side surfaces (upper and lower side surfaces) of the crossbeam body 1 in the height direction. In this embodiment, the support assembly is installed on the first side surface 101 and the third side surface 103. At the same time, in this embodiment, the crossbeam body 1 is connected to the vehicle body through the fourth side surface 104 (bottom surface).

[0038] Exemplarily, in this embodiment, the support assembly can also be arranged on the fourth side surface 104 (bottom surface). When the support assembly is arranged on the fourth side surface 104, it can also realize the support of the crossbeam body 1, and can also generate a buffer gap between the crossbeam body 1 and the vehicle body, which can achieve the same purpose and realize the required functions.

In this embodiment, the second contact portion 302 is in contact with the vehicle body through a plane, and a second fixing hole 306 is provided on the second contact portion 302. The number of the second fixing holes 306 can be set to one or more, which is used to connect with the tooling for easy positioning. After the positioning is completed through the second fixing holes 306, the second connection portion 301 is welded to the beam body 1 to fix the second support member 3 on the beam body 1. In this embodiment, the second connecting portion 301 is provided with a harness hole and a stop hole 303, and the number of the harness holes corresponds to the number of the stop holes 303, wherein the harness hole provides an installation position for the harness to be integrated on the front second support member 3, and plays a role in fixing the harness, and the stop hole 303 plays a role in preventing the harness on the harness hole from rotating and shaking.

[0044] Exemplarily, the third support member 4 in this embodiment is formed by stamping as a whole, and the third support member 4 includes a third connection portion 402 and a third contact portion 403, wherein the third connection portion 402 is fixed on the third side surface 103 and is fixed by welding, and the third contact portion 403 can be adaptively set according to the installation environment inside the vehicle body, such as a plane, a concave-convex, or an inclined shape, so as to achieve a matching relationship with the vehicle body and effectively abut against the vehicle body, so that the third support member 4 has a stable support function. The third contact portion 403 in this embodiment is in contact with the vehicle body through a plane, and a third fixing hole 401 is provided on the third contact portion 403. The number of the third fixing holes 401 can be set to one or more, which is used to connect with the tooling for easy positioning. After the positioning is completed through the third fixing hole 401, the third connection portion 402 is welded to the beam body 1 to fix the third support member 4 on the beam body 1. In this embodiment, a plurality of second reinforcing ribs 404 are also provided on the third connection portion 402 to improve the overall strength of the third support member 4.

[0045] It is worth mentioning that in the present embodiment, the first support member 2, the second support member 3 and the third support member 4 are all installed on the beam body 1 by welding. During the processing, corresponding tooling is used to fix the three to the beam body 1 to facilitate the welding process. A processing hole 7 is provided on the beam body 1. The processing hole 7 is used for the installation of the beam body 1, so that the beam body 1 can be fixed to the corresponding tooling through the processing hole 7, which is conducive to the effective connection between the beam body 1 and the support members.

[0046] It should also be noted that in this embodiment, two wire harness holes 8 are provided on the crossbeam body 1 to provide installation points for the wire harness to be integrated on the crossbeam body 1, so that the integration of the seat crossbeam assembly is higher. A leakage hole is also provided on the crossbeam body 1, which is used to leak electrophoretic liquid when the crossbeam body 1 is welded to the white body and then electrophoretically coated.
