Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, specifically to a high-strength lightweight aluminum profile for automobiles. Background Technology
[0002] The development of the automotive industry has always revolved around three major themes: safety, environmental protection, and energy conservation. As the first line of defense in a vehicle's passive safety system, the front and rear anti-collision beam assemblies are of paramount importance. In the event of a collision, they effectively absorb energy through deformation, reducing the impact on the passenger compartment and ensuring the safety of occupants.
[0003] Traditional crash beams are mostly made of steel, which, while strong, is heavy and detrimental to lightweight vehicle design and fuel economy. Some single-layer plate-shaped or simple hat-shaped aluminum crash beams may lack sufficient bending stiffness and strength, especially in high-speed or offset collisions, making them prone to local instability or premature fracture, resulting in unsatisfactory energy absorption efficiency.
[0004] Based on the above, this utility model proposes a high-strength lightweight aluminum profile for automobiles, which can effectively solve the above problems. Utility Model Content
[0005] This utility model addresses the shortcomings of the existing technology by providing a high-strength, lightweight aluminum profile for automobiles.
[0006] This utility model is achieved through the following technical solution: A high-strength, lightweight aluminum profile for automobiles includes a crash beam body. The crash beam body includes an outer crash beam and an inner crash beam disposed inside the outer crash beam. The outer crash beam and the inner crash beam are welded together. Energy-absorbing boxes are inserted into the outer crash beam and welded together with it. A mounting plate is welded to the side of the energy-absorbing box away from the crash beam body.
[0007] According to the above technical solution, as a further preferred technical solution, the energy-absorbing box includes an upper U-shaped plate and a lower U-shaped plate, and the two side walls of the upper U-shaped plate are attached to each other and connected by welding.
[0008] According to the above technical solution, as a further preferred technical solution, the bottom ends of the outer anti-collision beam are respectively provided with inverted L-shaped connecting blocks, the connecting blocks are welded to the outer anti-collision beam, and the connecting blocks are provided with through holes.
[0009] According to the above technical solution, as a further preferred technical solution, fixing holes are respectively opened at the four corners of the mounting plate.
[0010] Compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model provides a high-strength, lightweight aluminum profile for automobiles. By adopting a composite structure formed by welding an outer anti-collision beam and an inner anti-collision beam, the overall rigidity and impact resistance of the anti-collision beam body are significantly improved. Furthermore, the energy-absorbing box is inserted into the outer anti-collision beam and welded to ensure that the collision force can be stably transferred from the anti-collision beam body to the energy-absorbing box, which serves as the crumple zone. The mounting plate welded to the other end of the energy-absorbing box facilitates a firm and stable connection with the vehicle body, thereby achieving the goal of lightweighting while ensuring safety.

Detailed Implementation
[0012] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.
[0013] A high-strength lightweight aluminum profile for automobiles includes a crash beam body 1, wherein the crash beam body 1 includes an outer crash beam 11 and an inner crash beam 12 disposed inside the outer crash beam 11, the outer crash beam 11 and the inner crash beam 12 are welded together; an energy-absorbing box 2 is inserted into the outer crash beam 11 and welded together with it; a mounting plate 3 is welded to the side of the energy-absorbing box 2 away from the crash beam body 1.
[0014] This utility model significantly improves the overall rigidity and impact resistance of the anti-collision beam body 1 by adopting a composite structure formed by welding the outer anti-collision beam 11 and the inner anti-collision beam 12. Furthermore, by inserting the energy-absorbing box 2 into the outer anti-collision beam 11 and welding it, it is ensured that the collision force can be stably transferred from the anti-collision beam body 1 to the energy-absorbing box, which serves as the crumple zone. The mounting plate welded to the other end of the energy-absorbing box facilitates a firm and stable connection with the vehicle body, thereby achieving the goal of lightweighting while ensuring safety.
[0015] Furthermore, in another embodiment, the energy-absorbing box 2 includes an upper U-shaped plate 21 and a lower U-shaped plate 22, wherein the two side walls of the upper U-shaped plate 21 and the two side walls of the lower U-shaped plate 22 are attached to each other and connected by welding.
[0016] The energy-absorbing box 2 is formed by welding together an upper U-shaped plate 21 and a lower U-shaped plate 22. When subjected to axial impact, this hollow thin-walled structure can undergo stable and controllable wrinkling deformation along the preset weld seam, thus absorbing impact energy more efficiently and predictably than a solid or integral structure.
[0017] Furthermore, in another embodiment, the bottom ends of the outer anti-collision beam 11 are respectively provided with inverted L-shaped connecting blocks 4, which are welded to the outer anti-collision beam 11, and the connecting blocks 4 are provided with through holes 41.
[0018] By setting up connecting block 4 and through hole 41, additional mounting and connection points are provided, which can be used to install other components at the front of the vehicle, such as pedestrian anti-roll-in beams, front bumper underguards, or sensor harnesses, thereby enhancing the integration of the vehicle's front functions.
[0019] Furthermore, in another embodiment, the mounting plate 3 has fixing holes 31 at its four corners.
[0020] By setting the fixing hole 31, a firm and stable connection with the vehicle body is achieved.
[0021] Based on the description and drawings of this utility model, those skilled in the art can easily manufacture or use the high-strength lightweight aluminum profile for automobiles of this utility model, and can achieve the positive effects described in this utility model.
