[0002] Aluminum alloy profiles are alloys with aluminum as the base and a certain amount of other alloying elements added. They are one of the light metal materials. In addition to the general properties of aluminum, aluminum alloys also have some specific alloy properties due to the different types and amounts of alloying elements added. The density of aluminum alloy is 2.63 - 2.85 g / cm3, and it has relatively high strength (σb is 110 - 650 MPa). Its specific strength is close to that of high alloy steel, and its specific stiffness exceeds that of steel.

[0003] Aluminum alloy profiles are widely used, including anti-collision beam structures made of aluminum alloy. When the existing aluminum profile anti-collision beam is in use, although it has good structural strength, when the beam body is subjected to external impact, its actual buffer and energy absorption effect is poor, and the internal support strength of the hollow beam body is not high, making it prone to deformation, which reduces the overall use effect of the aluminum profile anti-collision beam.

The inside of the beam-column energy-absorbing box is designed with a hollow structure. An energy-absorbing spring is fixedly installed inside the beam-column energy-absorbing box.

[0023] Please refer to Figures 1-5 , an embodiment provided by the present utility model: a lightweight anti-collision beam for aluminum profiles, including an outer anti-collision beam 1, specifically as shown in the attached drawings of the specification Figure 1As shown in the figure, the outer anti-collision beam 1 is arranged in an arc structure. The inside of the outer anti-collision beam 1 is designed with a hollow structure. A central support plate 2 is fixedly installed inside the outer anti-collision beam 1. The central support plate 2 can support the plate body in the middle of the hollow structure inside the outer anti-collision beam 1, so as to achieve better structural strength, make the inside of the outer anti-collision beam 1 have a certain hollow support, improve the support strength. Above and below the central support plate 2 and inside the outer anti-collision beam 1, triangular strengthening members 3 are fixedly installed. In the present utility model, two symmetrically distributed triangular strengthening members 3 are installed inside the outer anti-collision beam 1. The two diagonal support members of the triangular strengthening member 3 can form a stable internal triangular support structure. During actual use, the structural support strength inside the outer anti-collision beam 1 can be effectively improved, and the external force can be better resisted, with a high support strength. Thus, the overall structural hardness of the outer anti-collision beam 1 can be effectively improved. Through the hollow structure design of the outer anti-collision beam 1, adding internal strengthening structures in the hollow structure can effectively save product materials, and compared with solid beams, the overall product weight can also be effectively reduced. It is convenient to use and has the technical characteristics of light weight;

[0024] Specifically refer to the attached drawings of the specification Figure 3 and Figure 4 As shown in the figure, a number of energy-absorbing metal sheets 4 are fixedly installed at equal intervals in the triangular gap of the triangular strengthening member 3. The energy-absorbing metal sheets 4 are made of elastic metal and are designed in a serpentine structure;

[0025] With this structural design, when the outer anti-collision beam 1 is subjected to external force impact, the outermost stress surface is subjected to impact force. The impact force acting on the outer anti-collision beam 1 may cause the outer panel to dent and deform. When the outer anti-collision beam 1 dents and deforms, the dented part will push the internal energy-absorbing metal sheet 4. Since the energy-absorbing metal sheet 4 is designed in a serpentine structure, when the dented part pushes the energy-absorbing metal sheet 4, it will cause the energy-absorbing metal sheet 4 to deform. Thus, the serpentine plate spacing can provide a certain deformation space for the deformation, avoiding the impact force directly acting on the rear structure through the beam body. And the energy-absorbing metal sheet 4 during the deformation process has a certain metal resilience. Thus, part of the external force energy can be absorbed through the resilience effect generated by the deformation, and preliminary buffer energy absorption work can be carried out, which has good practicability;

[0026] The outer anti-collision beam 1, the central support plate 2 and the triangular strengthening member are designed with an integrally formed structure. On both sides of the back of the outer anti-collision beam 1, rear welding seats 5 are fixedly installed. At one end of the rear welding seat 5 away from the outer anti-collision beam 1, a beam-column energy-absorbing box 6 is fixedly installed. The inside of the beam-column energy-absorbing box 6 is designed with a hollow structure. An energy-absorbing spring 7 is fixedly installed inside the beam-column energy-absorbing box 6;

[0027] According to the above structure, when the impact force is too large, after the impact force deforms the energy-absorbing metal sheet 4, the impact force will be transmitted to the beam-column energy-absorbing box 6 through the main beam structure of the outer anti-collision beam 1, so that the outer anti-collision beam 1 squeezes the beam-column energy-absorbing box 6 under the action of the impact force, causing it to produce an impact extrusion deformation. The deformation process of the beam-column energy-absorbing box 6 can absorb part of the impact energy. At the same time, the extrusion deformation process of the beam-column energy-absorbing box 6 will compress the internal energy-absorbing spring 7, so that a certain elastic reaction force can be obtained through the compression of the energy-absorbing spring 7. In this way, the external force can be absorbed and resisted through the compression reaction force of the energy-absorbing spring 7, and it has a secondary elastic buffer energy-absorbing effect during actual use. Through the combined use of two groups of buffer energy-absorbing structures, the intrusion amount of the plate body can be effectively reduced, the harm caused by collisions can be reduced, and it has good beam structure strength and buffer performance, and good use performance;

[0028] As an optimized technical solution of the present invention, a damper can be installed in the energy-absorbing spring 7, so that the spring energy-absorbing effect can be further provided through the damper, and it has good protection;

[0029] Furthermore, a rear connecting beam 8 is fixedly installed at one end of the beam-column energy-absorbing box 6 away from the end connecting seat, and a rear mounting plate 9 is fixedly installed at the tail end of the rear connecting beam 8.

[0030] In this embodiment, in order to facilitate the installation of the anti-collision beam of the present invention on the external structure through the rear mounting plate 9, through holes 10 are opened at the four corners of the outer surface of the rear mounting plate 9, and the through holes 10 are designed as through-hole structures.

[0031] In this embodiment, in order to ensure that the present invention has a certain structural strength and at the same time has the technical characteristics of lightweight use, the outer anti-collision beam 1, the beam-column energy-absorbing box 6 and the rear connecting beam 8 are all made of aluminum alloy materials. Making the outer anti-collision beam 1, the beam-column energy-absorbing box 6 and the rear connecting beam 8 with aluminum alloy materials can ensure a certain structural strength and at the same time have a light weight, with the technical characteristics of lightweight use.

[0032] Working principle: During actual use, the outer anti-collision beam 1 of the present invention can be installed on an external protected structure through the rear mounting plate 9 and the through holes 10, such as the car body, etc.;

[0033] In the present invention, a central support plate 2 is fixedly installed inside the outer anti-collision beam 1. By setting the central support plate 2, the internal hollow structure of the outer anti-collision beam 1 can be supported by a plate in the middle, so that better structural strength can be achieved, the inner part of the outer anti-collision beam 1 has a certain hollow support, and the support strength is improved;

[0034] Meanwhile, in the utility model, two groups of symmetrically distributed triangular reinforcement members 3 are installed inside the outer anti-collision beam 1. The two diagonal support members of the triangular reinforcement member 3 can form a stable internal triangular support structure. During actual use, the structural support strength inside the outer anti-collision beam 1 can be effectively improved, and the external force can be better resisted, with a high support strength. Thus, the overall structural hardness of the outer anti-collision beam 1 can be effectively improved. Through the hollow structure design of the outer anti-collision beam 1, adding internal reinforcement structures inside the hollow structure can effectively save product materials, and compared with solid beams, the overall product weight can also be effectively reduced. It is convenient to use and has the technical characteristics of lightweight use;

[0035] When the outer anti-collision beam 1 is subjected to external force impact, the outermost stress surface is subjected to impact force. The impact force acting on the outer anti-collision beam 1 may cause the outer panel to dent and deform. When the outer anti-collision beam 1 dents and deforms, the dented part will push the internal energy-absorbing metal sheet 4. Since the energy-absorbing metal sheet 4 is designed with a serpentine structure, when the dented part pushes the energy-absorbing metal sheet 4, the energy-absorbing metal sheet 4 will deform. Thus, the serpentine plate spacing can provide a certain deformation space for the deformation, avoiding the impact force directly acting on the rear structure through the beam body. And the energy-absorbing metal sheet 4 during the deformation process has a certain metal resilience. Thus, a part of the external force energy can be absorbed through the resilience effect generated by the deformation, and preliminary buffer energy absorption work can be carried out, with good practicability;

[0036] Among them, when the impact force is too large, after the impact force causes the energy-absorbing metal sheet 4 to complete deformation, the impact force will be transmitted to the beam-column energy-absorbing box 6 through the main beam structure of the outer anti-collision beam 1, so that the outer anti-collision beam 1 squeezes the beam-column energy-absorbing box 6 under the action of the impact force, causing it to have an impact extrusion deformation. The deformation process of the beam-column energy-absorbing box 6 can absorb a part of the impact energy. At the same time, the extrusion deformation process of the beam-column energy-absorbing box 6 will compress the internal energy-absorbing spring 7. Thus, a certain elastic reaction force can be generated through the compression of the energy-absorbing spring 7. By using the compression reaction force of the energy-absorbing spring 7 to absorb and resist the external force, a secondary elastic buffer energy absorption effect can be achieved during actual use. Through the combined use of two groups of buffer energy absorption structures, the intrusion amount of the plate body can be effectively reduced, the harm generated during a collision can be reduced, and it has good beam structure strength and buffer performance effect, with good use performance.
