[0027] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0028] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0029] like Figure 2 and Figure 3 As shown, this embodiment discloses a seat crossbeam assembly, including a crossbeam body 1, a reinforcing member 2, and a supporting member 3. The supporting member 3 is installed below the crossbeam body 1, and a mounting cavity is formed between the supporting member 3 and the crossbeam body 1. The reinforcing member 2 is disposed within the mounting cavity and is connected to the crossbeam body 1 and / or the supporting member 3. The reinforcing member 2 improves the rigidity and strength of the crossbeam body 1, and the supporting member 3 provides support and fixation for the reinforcing member 2, further improving the rigidity and strength of the crossbeam body 1. With the above configuration, the seat crossbeam assembly in this embodiment has fewer parts and a simpler structure compared to the prior art. Furthermore, the inclusion of the reinforcing member 2 and the supporting member 3 enables the crossbeam assembly to possess greater rigidity and strength.

[0030] In this embodiment, multiple support members 3 are provided, which are spaced apart along the length of the beam body 1 and preferably evenly distributed on the beam body 1. Specifically, there are three support members 3, which are spaced apart along the length of the beam body 1 and connected to the beam body 1. These three support members 3 support the reinforcing member 2, preventing it from detaching from the beam body 1. Furthermore, the three support members 3 are evenly spaced to evenly support the reinforcing member 2, avoiding uneven stress. During installation, the reinforcing member 2 and support members 3 are first connected together, and then the small assembly of the reinforcing member 2 and support members 3 is connected to the beam body 1, thus completing the reinforcement of the beam body 1.

[0031] Specifically, the crossbeam body 1 includes a main crossbeam 11 with a Z-shaped cross-section and crossbeam side plates 12. The crossbeam side plates 12 are located at both ends of the main crossbeam 11, and the reinforcing member 2 and the supporting member 3 are both connected to the lower part of the main crossbeam 11. Figure 6 As shown, the crossbeam body 1 in this embodiment includes a crossbeam main plate 11 and a crossbeam side plate 12. The cross-sections of the crossbeam main plate 11 and the crossbeam side plate 12 are both U-shaped. The crossbeam side plate 12 is disposed at both ends of the crossbeam main plate 11, and the crossbeam main plate 11 and the crossbeam side plate 12 are connected.

[0032] In this embodiment, mounting brackets 4 are also provided. Multiple mounting brackets 4 are connected to the side of the crossbeam body 1 away from the reinforcing member 2. The mounting brackets 4 are used to install the seat, thereby completing the connection between the seat crossbeam assembly and the seat. Specifically, there are four mounting brackets 4. The connection between the mounting brackets 4 and the crossbeam body 1 is provided with plug welding holes. The four mounting brackets 4 are connected to the crossbeam body 1 by welding.

[0033] Furthermore, the side of the crossbeam body 1 away from the reinforcing member 2 has multiple plug weld holes, and the side of the support member 3 facing the reinforcing member 2 also has multiple plug weld holes. Both the reinforcing member 2 and the support member 3 are connected to the lower part of the crossbeam main board 11. The crossbeam body 1 has plug weld holes, and the connection between the crossbeam body 1 and the mounting bracket 4 can be achieved by welding. The support member 3 has plug weld holes, and the connection between the support member 3 and the crossbeam main board 11 can also be achieved by welding.

[0034] In addition, the cross-section of the reinforcing member 2 is square, and the reinforcing member 2 has a cavity along its length. For example... Figure 4 and Figure 5 As shown, the reinforcing member 2 in this embodiment has a square cross-section, and a cavity extends through its length, thus forming a square tubular structure. Furthermore, the reinforcing member 2 is made of ultra-high-strength steel (2000MPa). By using this high-strength material, the moment of inertia of the reinforcing member 2's cross-section is significantly increased, thereby improving its stiffness. This also enhances the bending resistance of the beam body 1, preventing it from bending when subjected to a frontal impact.

[0035] In this embodiment, both the reinforcing member 2 and the supporting member 3 are located in the middle of the width direction of the beam body 1. The width of the supporting member 3 is greater than the width of the reinforcing member 2, and the width of the supporting member 3 is less than the width of the beam body 1. Figure 5As shown, in this embodiment, the reinforcing member 2 is located at the lower center of the crossbeam body 1, and the supporting member 3 is located at the lower center of the reinforcing member 2. The width of the supporting member 3 is smaller than the width of the crossbeam body 1. The supporting member 3 is connected to the crossbeam body 1, and the supporting member 3 and the crossbeam body 1 form a receiving cavity to accommodate the reinforcing member 2. Through the above arrangement, the force on the reinforcing member 2 and the supporting member 3 in the width direction can be evenly distributed, avoiding damage to the reinforcing member 2 and the supporting member 3 due to uneven force distribution.

[0036] Furthermore, both the crossbeam body 1 and the reinforcing member 2 are manufactured using a roll forming process. Compared to traditional stamping, roll forming offers several advantages: it allows for the use of ultra-high-strength steel grades of 500MPa, 1700MPa, 2000MPa, and above, achieving overall vehicle lightweighting. After the steel strip is roll-formed, the crossbeam body 1 has a U-shaped cross section, while the reinforcing member 2 has a U-shaped cross section with a break. High-frequency welding is then performed at the break point to form a closed U-shaped structure.

[0037] Considering that the main cause of beam deformation is that the beam is prone to bending deformation when subjected to impact forces along its length, in some embodiments, such as Figure 5 As shown, the top surface of the beam body 1 has a recess that faces into the mounting cavity. The top end of the reinforcing member 2 abuts against the recess, and the bottom end of the reinforcing member 2 abuts against the support member 3. The beam body with this recess is less prone to bending and deformation when subjected to impact force in its length direction.

[0038] In this embodiment, the crossbeam body 1 has a bend, and the radius of the bend is 2 to 5 times the thickness of the crossbeam body 1. Specifically, the radius of the bend is 4 times the thickness of the crossbeam body 1. In this embodiment, the crossbeam body 1 is formed by roll forming. When the sheet metal is bent by roll forming, the possibility of the sheet metal breaking at the bend is very low when the radius of the bend is 4 times the thickness of the sheet metal, and the rebound deformation of the sheet metal during bending is also very low. In order to reduce the breakage of the crossbeam body 1 at the bend during roll forming and reduce the rebound deformation during bending, the radius of the bend is set to 4 times the thickness of the crossbeam body 1.

[0039] Specifically, the support member 3 includes a support body 31 and a connecting part 32. The connecting part 32 is disposed on both sides of the support body 31 and is connected to the bottom of the crossbeam main plate 11. The support body 31, the connecting part 32, and the crossbeam main plate 11 constitute a mounting cavity. Figure 5As shown, the support member 3 in this embodiment includes a support body 31 and a connecting part 32. The support body 31 has a U-shaped structure and is located on the side of the reinforcing member 2 away from the crossbeam body 1. Connecting parts 32 are provided at both ends of the support body 31, and the connecting parts 32 are used to connect the support member 3 to the crossbeam body 1. The U-shaped structure of the support body 31 allows it to completely cover the underside of the reinforcing member 2 and connect to the crossbeam body 1 through the connecting parts 32, thereby providing support for the reinforcing member 2 and preventing it from detaching from the crossbeam body 1. During connection, the three support members 3 are first welded to the reinforcing member 2 to form a small assembly. Then, the small assembly is spot-welded to the crossbeam body 1 through the support members 3. The mounting bracket 4 and the crossbeam side plate 12 are connected to the crossbeam main plate 11 through welding. The crossbeam body 1 and the front floor panel are spot-welded to the floor.
