[0012] As a preferred embodiment, the beam body is designed with a circular cross-section, which is a gradually changing circular cross-section from the outer end to the inner end, and the circular cross-section has a smooth transition with equal thickness and is hollow in the middle.

[0013] The technical effect of adopting the above further solution is: This design optimizes the material distribution, ensures the structural strength while reducing the weight, and improves the overall performance.

[0014] As a preferred embodiment, the beam body, the side hanging plate, the black end hanging plate, the high-voltage wire fixing boss, the wheel cover mounting boss, the first reinforcing rib, and the second reinforcing rib are all made of high-grade ductile iron and are integrally cast and formed.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] This embodiment provides a technical solution. As Figures 1 to 4 shown, a frame crossbeam includes a beam body 1, a side hanging plate 2 is fixedly connected to the beam body 1, a wheelhouse mounting boss 5 for fixing the wheelhouse support is fixedly connected to the middle position of the beam body 1, a black end hanging plate 3 and an outer end mounting hanging plate 8 are respectively arranged on both sides of the beam body 1, two high-voltage wire fixing bosses 4 are arranged on the top of the beam body 1, and a first reinforcing rib 6 and a second reinforcing rib 7 are fixedly connected to the beam body 1;

[0028] In the present utility model, by optimizing the weight distribution and material utilization, the vehicle weight is reduced, thereby improving the fuel efficiency and power performance of the vehicle. At the same time, using high-grade ductile iron and adopting integral casting molding ensures the durability and reliability of the product, extends the service life. In addition, the integrated multiple installation functions simplify the assembly process, improve the assembly efficiency, reduce the manufacturing and assembly costs. The cross arrangement of the reinforcing ribs further enhances the load-bearing capacity of the crossbeam, enabling the vehicle to adapt to various complex working conditions, overall enhancing the vehicle performance and driving safety. These comprehensive effects provide a better driving experience and a longer service life for the vehicle, ensuring the stability and reliability of the vehicle under various driving conditions.

[0029] Furthermore, as Figures 1 to 4 shown, an installation opening is provided on the beam body 1. The black end hanging plate 3 and the outer end installation hanging plate 8 are both fixedly connected to the installation opening on the beam body 1. The outer end hanging plate is used to stabilize and fix the position of the cross beam in the vehicle frame, ensuring that when the cross beam is subjected to an external force, it can effectively transfer the force to other parts of the vehicle frame, thereby enhancing the rigidity and stability of the entire vehicle frame structure. The black end hanging plate 3 is relatively strong to ensure the stability and reliability of the connection under various complex working conditions.

[0030] The first reinforcing rib 6 and the second reinforcing rib 7 are both installed at the middle position of the beam body 1. The function of the reinforcing rib is to enhance the overall strength of the cross beam.

[0031] The beam body 1 is designed with a circular cross-section, which is a gradually changing circular cross-section from the outer end to the inner end. The circular cross-section has a smooth transition with equal thickness and is hollow in the middle. This design optimizes the material distribution, ensures the structural strength while reducing the weight, and improves the overall performance.

[0032] The beam body 1, the side hanging plate 2, the black end hanging plate 3, the high-voltage wire fixing boss 4, the wheel cover mounting boss 5, the first reinforcing rib 6, and the second reinforcing rib 7 are all made of high-grade ductile iron and are integrally cast. The integral casting improves the production efficiency, reduces the manufacturing defects, and ensures the consistency and reliability of the product.

[0033] In the above solution, there is also a problem that the strength of the beam body 1 may not be sufficient. As Figures 1 to 4 shown, the first reinforcing rib 6 and the second reinforcing rib 7 are cross-set, and the outer end position is provided with an adaptive notch for avoidance according to the boundary interface. A hollow design is adopted, and the overall structure is strengthened by adding cross-shaped reinforcing ribs.

[0034] Working principle:

[0035] As Figures 1-4 shown: The black end hanging plate 3 and the outer end installation hanging plate 8 stably connect the cross beam between the inner longitudinal beam and the outer side beam of the vehicle frame, ensuring that when the cross beam is subjected to an external force, it can effectively transfer the force to other parts of the vehicle frame, thereby enhancing the rigidity and stability of the entire vehicle frame structure. The wheel cover mounting boss 5 is used to fix the wheel cover support platform, which helps to disperse the load in the wheel area, while the high-voltage wire fixing boss 4 provides a fixing point for the high-voltage wire harness, ensuring the stability and safety of the wire harness. The cross-setting of the first reinforcing rib 6 and the second reinforcing rib 7, and their installation at the middle position of the beam body 1 significantly improve the overall strength of the cross beam, enabling the cross beam to better withstand the usage requirements of the vehicle under various complex working conditions.
