Description

Technical Field

[0001] This utility model relates to the field of automotive safety technology, specifically to a high-strength aluminum profile anti-collision beam for automotive bodies. Background Technology

[0002] High-strength aluminum profile anti-collision beams are automotive safety components made of aluminum alloy through extrusion or forging processes. They combine the lightweight and high-strength characteristics of aluminum, and are also corrosion-resistant. They can efficiently absorb energy and disperse impact force during a collision, making them a key structure for improving vehicle safety and energy efficiency.

[0003] Anti-collision beams are a key measure to improve the passive safety of automobiles. In a collision, the anti-collision beam acts as the first line of defense, absorbing most of the impact energy through its controllable deformation, reducing the direct transmission of collision force to the passenger compartment, and protecting the safety of the occupants. At the same time, its structural design can disperse the remaining energy to the longitudinal beams and chassis structure, avoiding localized concentrated force that could lead to severe deformation of the vehicle body. However, traditional anti-collision beams are mostly made of steel, which, although strong, is heavy and dense, increasing the overall weight of the vehicle body and affecting its range. Furthermore, their energy-absorbing design is often simplistic, with some steel anti-collision beams having simple energy-absorbing box structures that do not fully collapse during a collision, making it difficult to effectively disperse the impact force. This can lead to excessive localized force, threatening the safety of the passenger compartment. In addition, the difficulty in processing and forming steel limits the realization of complex energy-absorbing structures, affecting the overall improvement of protective performance.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 As shown, a high-strength aluminum profile anti-collision beam for automobile body includes a main beam 1 and a silicone block 2. The silicone block 2 is disposed on the inner wall of the main beam 1. An energy-absorbing component 3 is disposed on one side of the silicone block 2. The energy-absorbing component 3 includes a multi-chamber 31 fixed to one side of the silicone block 2. The inner wall of the multi-chamber 31 is fixed with partitions 32, and the number of partitions 32 is multiple. A compression component 4 is disposed on one side of the energy-absorbing component 3. The compression component 4 includes grooves 41 disposed on one side of the energy-absorbing component 3, and the number of grooves 41 is upper and lower. An extrusion block 42 is fixed to the inner wall; the energy-absorbing component 3 also includes a first reinforcing rib 33 penetrating the inner wall of the partition 32, and there are multiple sets of the first reinforcing ribs 33; the main beam 1 is the main force-bearing surface when it is impacted. When the main beam 1 is impacted, the impact force will first be transmitted to the silicone block 2. The silicone block 2 is set to buffer the impact force, thereby reducing the impact intensity during the collision. The energy-absorbing component 3 is the main force-bearing component during the collision, and the entire energy-absorbing component 3 is made of 6351 aluminum alloy. This high-strength aluminum alloy is heat-treated. It can achieve a high yield strength ≥280MPa and tensile strength ≥320MPa, while maintaining good ductility and elongation at break ≥10%, effectively withstanding impact forces. The impact force is transferred to the energy-absorbing component 3 by the silicone block 2. The multi-chamber 31 can effectively reduce the impact force during collision. The complex but orderly structure of the multiple sets of baffles 32 can assist the multi-chamber 31 in blocking more impact forces. Multiple sets of first reinforcing ribs 33 penetrate the baffles 32, which can improve the stability of the energy-absorbing component 3 when a collision occurs. The reinforcing rib 33 is fixedly connected to the energy-absorbing box 5 to form an integrated structure. By setting the compression component 4, the collision kinetic energy can be effectively converted into plastic work of deformation to the maximum extent, thereby absorbing energy efficiently and avoiding low energy absorption efficiency caused by random bending or breakage. When a collision occurs, the impact force will preferentially cause the tip of the groove 41 to yield and deform, thus guiding the entire beam from the groove 41 like a predetermined "crease" to fold and crush in a stable, gradual and predictable manner. The setting of the compression block 42 can improve the stability of the groove 41.

[0017] Two sets of energy-absorbing boxes 5 are bolted to the inner wall of the main beam 1. A mounting plate 6 is fixed to one side of each set of energy-absorbing boxes 5. A connecting box 7 is bolted to one side of the mounting plate 6, and a fixing block 8 is fixed to one side of the compression block 42. There are multiple sets of fixing blocks 8. One side of each set of energy-absorbing boxes 5 is bolted to the inner walls of both sides of the main beam 1. The arrangement of the two sets of energy-absorbing boxes 5 can effectively withstand the impact force on both ends of the main beam 1. The mounting plate 6 is used to fix the energy-absorbing boxes 5 to the connecting box 7. The connecting box 7 can improve the overall stability of the mounting plate 6 and the energy-absorbing boxes 5. When a collision occurs, multiple sets of fixing blocks 8 are used to transmit the residual force generated by the compression component 4. In addition, multiple sets of fixing blocks 8 can improve the stability of the compression block 42.

[0018] A stiffening plate 9 is fixed to one side of the fixing block 8, and one end of the stiffening plate 9 is fixed to one side of the connecting box 7. The stiffening plate 9, the fixing block 8, and the connecting box 7 form a stable triangular support system, which can effectively disperse the residual impact force transmitted by the compression component 4 and prevent local stress concentration. At the same time, the stiffening plate 9 is made of 7000 series aluminum alloy with a strength of over 500MPa, which is close to that of ordinary steel, but it is about 60% lighter and has better corrosion resistance.

[0019] Two sets of second reinforcing ribs 10 are provided on both the upper and lower sides of the stiffening plate 9, and one end of each set of second reinforcing ribs 10 is fixed to one side of the connecting box 7. The inner wall of the connecting box 7 is fixed with fixing posts 11, and there are multiple sets of fixing posts 11. Two sets of second reinforcing ribs 10 are provided on the top and bottom of the stiffening plate 9. The second reinforcing ribs 10 are auxiliary components of the stiffening plate 9. At the same time, the two ends of the second reinforcing ribs 10 pass through and are fixed inside the connecting box 7 to improve the overall resistance to torque. The fixing posts 11 inside the connecting box 7 can effectively improve the stability of the connecting box 7.

[0020] Working principle: When a vehicle collision occurs, the main beam 1, as the primary load-bearing surface, absorbs the impact. The silicone block 2 initially buffers the impact force, reducing the instantaneous impact intensity. The silicone block 2 disperses and weakens the impact force through its own elastic deformation, providing a more stable initial stress state for the subsequent energy-absorbing structure. Subsequently, the impact force is transmitted to the energy-absorbing component 3. The multi-chamber 31 and the partition 32 absorb energy through multi-stage collapse deformation. The first reinforcing rib 33 enhances structural stability and guides energy to be conducted to the energy-absorbing box 5. The groove 41 of the compression component 4 serves as a pre-set crease, guiding the beam to fold and crush in an orderly manner through tip yielding. The compression block 42 and... The fixed block 8 works in concert to convert deformation energy into controllable plastic work. The stiffening plate 9 and the second reinforcing rib 10 form a triangular support frame, which, together with the fixed column 11 in the connecting box 7, further disperses the remaining impact force to the longitudinal beam of the vehicle body. The energy-absorbing box 5 can be modularly replaced by fixing it with bolts, reducing maintenance costs. This design uses lightweight aluminum (40%-60% weight reduction compared to steel) and the high strength characteristics of 6351 / 7000 series aluminum alloy (tensile strength ≥320MPa) to improve fuel economy while ensuring collision safety. Moreover, the multi-stage energy-absorbing structure improves energy absorption efficiency by more than 25% compared to traditional steel beams.
