Description

Technical Field

[0001] This utility model relates to the field of automotive frame longitudinal beams, and more specifically, to a reinforcement structure for automotive frame longitudinal beams. Background Technology

[0002] The longitudinal beams of a car frame are a critical component of the vehicle's structure. They bear the overall weight of the vehicle and serve as the main skeleton connecting the front and rear components, playing a vital role in the vehicle's stability, safety, and driving performance. Made of high-strength steel, these longitudinal beams not only effectively resist the impact of collisions, protecting passenger safety, but also ensure the vehicle's durability and reliability under complex road conditions. Their precise design, achieved through meticulous welding and assembly processes, forms a robust body support system, providing a solid foundation for the car and making it an indispensable core component of the modern automotive industry.

[0003] Existing automotive frame longitudinal beam reinforcement structures generally employ the method of welding an inner plate into the frame cavity to enhance structural strength. While the inner plate improves the rigidity and torsional resistance of the frame to some extent, its strength is still insufficient to fully meet the high requirements of modern automobiles for high-speed driving stability, collision safety, and long-term durability. A frame reinforced solely by an inner plate may not be able to adequately absorb and disperse impact forces, resulting in severe damage to the vehicle body structure and affecting passenger protection.

[0004] Therefore, we have made improvements to this by proposing a longitudinal beam reinforcement structure for automobile frames. Utility Model Content

[0029] To address the technical problems in the background section, the following automotive frame longitudinal beam reinforcement structure is provided:

[0030] Combination Figure 1 - Figure 4 As shown, the present invention provides a longitudinal beam reinforcement structure for an automobile frame, including a longitudinal beam body 1. The longitudinal beam body 1 is a hollow rectangular structure with an opening on one side, and a reinforcing beam 2 is provided inside the longitudinal beam body 1. The reinforcing beam 2 is also a hollow rectangular structure with an opening on one side. The opening sides of the longitudinal beam body 1 and the reinforcing beam 2 are arranged opposite to each other, and the reinforcing beam 2 is welded to the inside of the longitudinal beam body 1.

[0031] In this embodiment: the main body of the longitudinal beam 1 has an opening on one side, and a hollow rectangular reinforcing beam 2 with the same opening on one side is added inside the main body of the longitudinal beam 1. The opening sides of the two correspond to each other and are tightly connected by welding process to form a composite structure that is both lightweight and strong. This structure can significantly enhance the overall strength and rigidity of the frame longitudinal beam and effectively improve the stability and safety of the vehicle.

[0032] As a preferred embodiment, based on the above method, both sides of the longitudinal beam body 1 are welded with connecting flanges 3, and the connecting flanges 3 are provided with multiple bolt holes 4, and the thickness of the connecting flanges 3 is greater than the wall thickness of the longitudinal beam body 1.

[0033] In this embodiment: By welding connecting flanges 3 to both sides of the longitudinal beam body 1, these connecting flanges 3 are not only designed with multiple bolt holes 4 for fastening to other frame components, but their thickness is also increased, exceeding the wall thickness of the longitudinal beam body 1. This can enhance the connection strength and stability of the frame longitudinal beam to other key components, improve the durability of the overall structure, and ensure that the frame can maintain excellent structural integrity and passenger safety under various extreme driving conditions.

[0034] As a preferred embodiment, based on the above method, further, side reinforcing plates 5 are provided on both sides of one side surface of the longitudinal beam body 1, and the side reinforcing plates 5 are arc-shaped. Connectors 6 are installed on both sides of the side reinforcing plates 5, and bolt assemblies 9 are provided on the surface of the connector 6 on one side surface of the side reinforcing plates 5. The connector 6 is fixedly connected to the longitudinal beam body 1 by the bolt assembly 9. The connector 6 on the other side surface of the side reinforcing plates 5 is connected to the adjacent frame crossbeam.

[0035] In this embodiment, arc-shaped side reinforcing plates 5 are added to both sides of one side surface of the longitudinal beam body 1, which can enhance the lateral support force of the frame longitudinal beam and improve the torsional performance of the structure through its arc-shaped structure. The side reinforcing plates 5 are tightly connected to the longitudinal beam body 1 and the adjacent frame crossbeam through the connecting parts 6. One side of the connecting parts 6 is firmly fixed to the longitudinal beam body 1 through the bolt assembly 9, and the other side is reliably connected to the frame crossbeam. This not only significantly improves the overall strength and rigidity of the frame, but also ensures the stability and safety of the frame under complex road conditions and collisions.

[0036] As a preferred embodiment, based on the above method, a plurality of reinforcing ribs 7 are welded between the inner wall of the reinforcing beam 2 and the inner wall of the longitudinal beam body 1, and the reinforcing ribs 7 are arranged in a triangular shape.

[0037] In this embodiment, multiple triangular reinforcing ribs 7 are welded between the reinforcing beam 2 and the internal space of the longitudinal beam body 1. These triangular reinforcing ribs 7 can provide additional stability and strength support for the frame longitudinal beam, effectively disperse forces and torques from different directions, prevent the frame from deforming under complex stress environments, and significantly improve the overall fatigue resistance and durability of the frame.

[0038] As a preferred embodiment, based on the above method, a plurality of support plates 8 are welded between the inner wall of the reinforcing beam 2 and the inner wall of the longitudinal beam body 1, and the support plates 8 are all inclined, and the inclination directions of two adjacent support plates 8 are opposite.

[0039] In this embodiment, by welding multiple inclined support plates 8 between the inner wall of the reinforcing beam 2 and the inner wall of the longitudinal beam body 1, with adjacent support plates 8 having opposite inclination directions, the stability principle of triangles can be utilized to form a more complex and robust internal support network through the staggered arrangement of the support plates 8, which greatly enhances the torsional resistance and overall rigidity of the frame longitudinal beams. At the same time, the inclined support plates 8 also help to more effectively disperse and absorb impact forces from all directions, improving the safety performance of the frame in collision situations.

[0040] As a preferred embodiment, based on the above method, the reinforcing beam 2, the side reinforcing plate 5, the reinforcing rib plate 7 and the support plate 8 are all made of high-strength steel.

[0041] In this embodiment, key reinforcing components such as the reinforcing beam 2, side reinforcing plate 5, reinforcing rib plate 7, and support plate 8 are all made of high-strength steel. This material, with its excellent mechanical properties and outstanding durability, ensures the stability and safety of the frame longitudinal beams under extreme loads and complex stress environments; and can improve the overall strength and rigidity of the frame, extend its service life, and reduce the risk of structural damage caused by long-term fatigue.

[0042] Working principle:

[0043] During operation, the main longitudinal beam 1 serves as the primary load-bearing component of the chassis. Internally, reinforcing beams 2 are tightly welded together, forming a composite structure that effectively enhances the longitudinal load-bearing capacity of the chassis. Simultaneously, the arc-shaped design of the side reinforcing plates 5, along with the ingenious arrangement of the reinforcing ribs 7 and support plates 8, not only enhances the lateral support and torsional resistance of the chassis but also forms a complex internal support network, effectively dispersing and absorbing impact forces from all directions. The use of high-strength steel ensures the stability and durability of these reinforcing components under extreme loads and complex stress environments. When the vehicle travels on complex road conditions or encounters a collision, this reinforcing structure can respond rapidly, maintaining the integrity and stability of the chassis structure, thereby protecting passengers from injury.

[0044] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0045] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
