[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0058] As described in the background section, in actual manufacturing, the main beam, energy-absorbing box, and mounting plate of an automotive crash protection beam are formed by extrusion, aging, and machining processes, and then welded together. During the assembly of the main beam, energy-absorbing box, and mounting plate, strict control of thermal deformation is often required in terms of tooling fixtures and welding processes to achieve acceptable tolerance accuracy, resulting in a long development cycle and high production costs. To reduce the long development cycle and production costs of automotive crash protection beams, fastener connections are used instead of welding, but the risk of insufficient connection strength still exists. Therefore, the inventors of this application have designed a novel crash beam assembly that can at least improve the connection strength of the crash beam assembly. The crash beam assembly of this application will be described in detail below with reference to the accompanying drawings.
[0059] See Figures 1 to 13 As shown, according to a first aspect of this application, a crash beam assembly 100 is provided. The crash beam assembly 100 includes a main beam 10, an energy-absorbing component 20, and a locking assembly 30.
[0060] Specifically, the main beam 10 is provided with a plug-in portion 11. The energy-absorbing component 20 includes an integrally formed energy-absorbing box 21 and a mounting plate 22. The energy-absorbing box 21 is provided with a plug-in mating portion 211. The plug-in mating portion 211 is inserted into the main beam 10 through the plug-in portion 11. The mounting plate 22 is provided on the side of the energy-absorbing box 21 opposite to the main beam 10. The locking assembly 30 is used to lock the energy-absorbing component 20 to the main beam 10.
[0061] In this embodiment, the insertion part 11 on the main beam 10 and the insertion mating part 211 on the energy-absorbing box 21 cooperate with each other, allowing the energy-absorbing component 20 to be inserted into the main beam 10 to connect the energy-absorbing component 20 and the main beam 10 as a whole. The cooperation of the insertion part 11 and the insertion mating part 211 increases the contact area between the main beam 10 and the energy-absorbing box 21, thereby strengthening the connection between them. Simultaneously, when the main beam 10 is subjected to external impact, the larger contact area between the main beam 10 and the energy-absorbing box 21 can disperse some of the impact, improving the impact resistance of the anti-collision beam assembly 100. The locking component 30 can lock the energy-absorbing component 20 onto the main beam 10, ensuring the reliability and stability of the connection between the energy-absorbing component 20 and the main beam 10, and improving the connection strength between them.
[0062] Furthermore, the energy-absorbing box 21 and the mounting plate 22 are integrally formed, eliminating the welding process required in existing technologies, such as welding the energy-absorbing box 21 and the mounting plate 22 together. This also eliminates the need to control welding thermal deformation, improving the assembly efficiency of the crash beam assembly 100 and reducing its development cycle and production cost. Compared to existing technologies, the integrally formed structure of the energy-absorbing box 21 and the mounting plate 22 in this embodiment avoids weld seams between them, improving the connection strength and ensuring higher connection strength for the crash beam assembly 100.
[0063] like Figure 3 As shown, in some embodiments, the insertion part 11 includes an insertion groove 111. When the insertion mating part 211 is inserted into the insertion groove 111, the insertion mating part 211 contacts the inner wall surface of the insertion groove 111, thereby limiting the insertion mating part 211 in both the insertion direction and the direction perpendicular to the insertion direction. The insertion mating part 211 is precisely limited in the insertion groove 111, which can prevent relative displacement between the main beam 10 and the energy-absorbing box 21, ensuring higher assembly accuracy between the main beam 10 and the energy-absorbing component 20, and ensuring that the anti-collision beam assembly 100 has high connection strength. At the same time, when the insertion mating part 211 is inserted into the insertion groove 111, the opening of the insertion groove 111 can guide the insertion mating part 211 to be aligned, reducing alignment errors during insertion and improving the assembly efficiency and production cycle of the anti-collision beam assembly 100.
[0064] Specifically, when the main beam 10 is subjected to an external impact, the impact force borne by the main beam 10 is transmitted to the energy-absorbing box 21 through the side and bottom walls of the insertion groove 111. The bottom wall of the insertion groove 111 can bear part of the impact in the insertion direction, and the side wall of the insertion groove 111 can bear part of the impact perpendicular to the insertion direction, effectively preventing the locking component 30 from bearing excessive impact alone, thus improving the impact resistance of the anti-collision beam assembly 100. In addition, when the insertion mating part 211 and the insertion groove 111 have a reliable connection, the external impact can be accurately transmitted to the energy-absorbing box 21, causing the energy-absorbing box 21 to collapse and deform in a pre-designed form to absorb the energy of the impact, reducing the degree of damage to the main body of the vehicle 200.
[0065] In some embodiments, the plug portion 11 includes a plug hole. It is understood that the above embodiments can be implemented individually or simultaneously. That is, in some embodiments, the plug portion 11 may also be partially configured as a plug groove 111 and partially as a plug hole.
[0066] It is understood that the shape and size of the above-mentioned insertion groove 111 and insertion hole can be adjusted according to the actual situation. This embodiment does not make specific limitations. As long as the deformation mode can cooperate with the insertion mating part 211, it is within the protection scope of this embodiment.
[0067] like Figures 6 to 7 As shown, in some embodiments, the plug-in mating part 211 includes a plug-in plate 2111. When the plug-in plate 2111 mates with the plug-in part 11, it has a large contact area, ensuring a higher connection strength between the plug-in plate 2111 and the plug-in part 11. Furthermore, the plug-in plate 2111 has a simple structure, and its one-piece molding process requires less stringent mold requirements. It is less prone to air bubbles and cracks during the one-piece molding process, further ensuring high structural strength for the installation of the energy-absorbing component 20 and the anti-collision beam assembly 100. The plug-in plate 2111 also has good guiding properties, allowing it to be smoothly inserted into the plug-in part 11. Specifically, when the insertion part 11 includes the insertion groove 111, the insertion plate 2111 can be inserted into the insertion groove 111 along the groove depth direction. The insertion operation is simple, and the inner wall surface of the insertion groove 111 will automatically limit the insertion plate 2111 from shifting, which can improve the assembly efficiency of installing the energy-absorbing component 20 into the main beam 10.
[0068] In some embodiments, both the plug-in portion 11 and the plug-in mating portion 211 are included. During assembly, it is only necessary to align one plug-in portion 11 with one plug-in mating portion 211 and complete the plug-in action to accurately assemble the energy-absorbing component 20 onto the main beam 10. The plug-in operation is simple.
[0069] In other embodiments, multiple insertion portions 11 and multiple insertion mating portions 211 are included, and the multiple insertion portions 11 and multiple insertion mating portions 211 are arranged in a one-to-one correspondence. Multiple positional constraints can be formed between the main beam 10 and the energy-absorbing box 21 to limit the relative displacement between the main beam 10 and the energy-absorbing box 21, thereby reducing the connection gap between the main beam 10 and the energy-absorbing box 21 and improving the connection strength between the main beam 10 and the energy-absorbing box 21.
[0070] Understandably, the number of connectors 11 and mating parts 211 can be adjusted according to actual conditions. For example, the anti-collision beam assembly 100 of a larger vehicle 200 requires higher connection strength, and therefore needs to have more connectors 11 and mating parts 211. This embodiment allows for adjustment of the number of connectors 11 and mating parts 211 according to different vehicle models, optimizing development costs.
[0071] like Figure 3 As shown, in some embodiments, the main beam 10 includes a front plate 12, a top plate 13, a rear plate 14, and a bottom plate 15. The front plate 12, top plate 13, rear plate 14, and bottom plate 15 are integrally formed and connected end-to-end. A connector 11 is disposed on the rear plate 14. The integral formation of the front plate 12, top plate 13, rear plate 14, and bottom plate 15 provides high structural and connection strength, improving the structural strength and impact resistance of the anti-collision beam assembly 100, and also enhancing the reliability of the connection between the rear plate 14 and the connector 11. Compared to processing the front plate 12, top plate 13, rear plate 14, and bottom plate 15 separately and then connecting them, this embodiment reduces assembly operations, shortens the production cycle of the main beam 10, and reduces labor and material costs. This embodiment can also reduce the weight of the main beam 10, improving the overall vehicle lightweighting.
[0072] Of the main beam 10, the front plate 12 and the rear plate 14 are located closer to the main body of the vehicle 200. The longitudinal direction of the main beam 10 is the same as the longitudinal direction of the vehicle 200 (e.g., ...). Figure 1 (The direction indicated by the middle arrow X). The energy-absorbing box 21 is connected to the rear plate 14 via the plug-in part 11. The mounting plate 22 is disposed on the side of the energy-absorbing box 21 opposite to the main beam 10. The mounting plate 22 is connected to the main body of the vehicle 200 to connect the anti-collision beam assembly 100 to the main body of the vehicle 200. The height direction of the main beam 10 is the height direction of the vehicle 200 (e.g., the direction indicated by the middle arrow X). Figure 1 (The direction indicated by the middle arrow Z). The width direction of vehicle 200 (e.g., ...). Figure 1 The direction indicated by the middle arrow Y) is perpendicular to the X and Z directions.
[0073] In some embodiments, the main beam 10 further includes a reinforcing plate 16. For example, Figure 3As shown, the reinforcing plate 16 is disposed between the front plate 12 and the rear plate 14, and is integrally formed with the front plate 12 and the rear plate 14. The front plate 12 and the rear plate 14 are mainly used to withstand the impact during a collision of the vehicle 200. The reinforcing plate 16 disposed between the front plate 12 and the rear plate 14 can improve the structural strength of the main beam 10, disperse the impact force borne by the front plate 12 and the rear plate 14, significantly improve the bending and torsional resistance of the main beam 10, and reduce the degree of torsional deformation of the main beam 10 when it encounters a collision. The integral forming of the reinforcing plate 16 with the front plate 12 and the rear plate 14 can also enhance the structural strength of the main beam 10, improve the safety performance of the vehicle 200 in a collision, and facilitate processing and manufacturing, thereby improving the assembly efficiency of the anti-collision beam assembly 100.
[0074] In other embodiments, such as Figure 4 As shown, the reinforcing plate 16 is disposed between the top plate 13 and the bottom plate 15, and is integrally formed with the top plate 13 and the bottom plate 15. The top plate 13 is mainly used to withstand impacts from above (such as pressure transmitted from the vehicle frame), while the bottom plate 15 is mainly used to withstand impacts from below (such as the impact force of a ground protrusion). The reinforcing plate 16, disposed between the top plate 13 and the bottom plate 15, can disperse the impact force borne by the top plate 13 and the bottom plate 15, improve the impact resistance of the main beam 10, and thus improve the safety performance of the vehicle 200 in a collision.
[0075] like Figure 5 As shown, in some embodiments, reinforcing plates 16 are provided between the top plate 13 and the bottom plate 15, and between the front plate 12 and the rear plate 14, which can further improve the structural strength and impact resistance of the main beam 10, thereby improving the safety performance of the vehicle 200 in a collision. Furthermore, the reinforcing plates 16 separate the space within the main beam 10, which can improve the structural strength of the main beam 10, ensure that the main beam 10 is subjected to uniform stress, and that each part of the main beam 10 can share a certain load, thereby reducing the degree of deformation of the main beam 10 and improving the safety performance of the vehicle 200.
[0076] In other embodiments, the reinforcing plate 16 includes a single piece that is easy to manufacture, thereby achieving a lightweight design for the vehicle 200.
[0077] In other embodiments, the reinforcing plate 16 comprises multiple plates. Multiple reinforcing plates 16 enhance the structural strength and impact resistance of the main beam 10. Impacts on the outer wall of the main beam 10 can be more quickly dispersed to other parts through the multiple reinforcing plates 16, reducing stress concentration and thus minimizing deformation. The space within the main beam 10 also provides deformation space, allowing it to absorb energy through orderly compression deformation during collisions, thereby improving the impact resistance of the vehicle 200. Specifically, the number of reinforcing plates 16 can be set according to the actual needs of the vehicle 200, ensuring that the vehicle 200 has both high safety performance and lightweight design and low cost.
[0078] Optionally, the front plate 12 includes an arc-shaped plate, and the top end of the plug-in mating part 211 has an arc-shaped surface, which contacts and fits into the arc-shaped plate. During assembly, when the top end of the plug-in mating part 211 contacts the arc-shaped plate, it indicates that the plug-in mating part 211 has been installed in place. The arc-shaped plate can provide a certain limiting effect on the plug-in mating part 211. The fit between the arc-shaped surface and the arc-shaped plate makes the connection between the plug-in mating part 211 and the main beam 10 tighter, reducing the likelihood of gaps and displacement between the main beam 10 and the energy-absorbing box 21, thus improving the connection strength between the main beam 10 and the energy-absorbing box 21. In addition, the arc-shaped plate also has a certain buffering and energy-absorbing effect, absorbing part of the impact in the initial stage of a collision, which helps to improve the impact resistance of the anti-collision beam assembly 100.
[0079] like Figures 6 to 7As shown, in some embodiments, the energy-absorbing box 21 includes an upper rib 212, a lower rib 213, and a middle rib 214. The upper rib 212 and the lower rib 213 are spaced apart along the height direction of the anti-collision beam assembly 100. The middle rib 214 is disposed between the upper rib 212 and the lower rib 213 and is integrally formed with the upper rib 212 and the lower rib 213. The plug-in mating part 211 is disposed on the middle rib 214 and is integrally formed with the middle rib 214. The upper rib 212, the lower rib 213, the middle rib 214, and the plug-in mating part 211 are integrally formed, which facilitates processing and manufacturing, ensures the consistency of the quality of the energy-absorbing box 21, and effectively prevents the energy-absorbing box 21 from having connection gaps, thereby improving the connection strength between the various parts of the energy-absorbing box 21. The upper rib 212, lower rib 213, and intermediate rib 214 can disperse some of the impact, improve the structural strength and collapse energy absorption effect of the energy-absorbing box 21, and enhance the connection strength and reliability of the anti-collision beam assembly 100. The upper rib 212, lower rib 213, and intermediate rib 214 are integrally formed, creating a stable frame structure that improves the deformation resistance of the energy-absorbing box 21 during a collision, allowing it to absorb energy according to the preset collapse deformation. The intermediate rib 214, located between the upper rib 212 and lower rib 213, provides support and guidance during collapse deformation, reducing misalignment of the upper rib 212 and lower rib 213 due to uneven stress, and ensuring uniform collapse deformation of the energy-absorbing box 21.
[0080] like Figures 6 to 7 As shown, in some embodiments, the intermediate rib 214 is perpendicular to the upper rib 212 and the lower rib 213, which can enhance the structural stability of the energy-absorbing box 21, thereby strengthening the connection strength of the anti-collision beam assembly 100. When an external impact acts on the upper rib 212 or the lower rib 213, the force can be efficiently transmitted through the vertical intermediate rib 214, and the load of the upper rib 212 and the lower rib 213 can be more evenly distributed to the intermediate rib 214. The vertically arranged intermediate rib 214 can also enhance the torsional resistance of the energy-absorbing box 21 during the collapse deformation process, ensuring that the plug-in mating part 211 on the intermediate rib 214 always maintains a stable fit with the plug-in part 11 of the main beam 10, and ensuring that the anti-collision beam assembly 100 has reliable connection strength.
[0081] In some embodiments, such as Figures 6 to 7As shown, the plug-in mating part 211 is perpendicular to the intermediate rib 214, which facilitates processing and manufacturing and also improves the structural strength of the energy-absorbing box 21. Simultaneously, when external impacts are transmitted between the intermediate rib 214 and the plug-in mating part 211, it can reduce local stress concentration in the energy-absorbing box 21. The plug-in mating part 211, positioned perpendicular to the intermediate rib 214, ensures more even stress distribution between the plug-in mating part 211 and the intermediate rib 214. Combined with the vertical support of the intermediate rib 214, the upper rib 212, and the lower rib 213, a multi-directional synergistic force-bearing system is formed, making the plug-in mating part 211 less prone to tilting or breakage under impact forces, thus improving the connection strength and reliability of the anti-collision beam assembly 100.
[0082] like Figure 6 As shown, in some embodiments, the upper rib 212 is at least partially located at the top of the main beam 10, and the lower rib 213 is at least partially located at the bottom of the main beam 10. Thus, the upper rib 212 and lower rib 213 can surround at least a portion of the main beam 10, further improving the structural strength of the anti-collision beam assembly 100. During actual assembly, the locking assembly 30 passes through the main beam 10, the upper rib 212, the insertion mating part 211, and the lower rib 213 to lock the energy-absorbing component 20 to the main beam 10. The upper rib 212, the intermediate rib 214, and the lower rib 213 surrounding the main beam 10 increase the contact area between the energy-absorbing box 21 and the main beam 10, further strengthening the connection strength between the main beam 10 and the energy-absorbing box 21, thereby improving the connection strength of the anti-collision beam assembly 100. The locking component 30 is installed through the main beam 10 and locks the energy-absorbing component 20 to the main beam 10, which enhances the reliability of the connection between the energy-absorbing component 20 and the main beam 10, ensures that the energy-absorbing component 20 is stably connected to the main beam 10, and can improve the connection strength of the anti-collision beam assembly 100.
[0083] Among them, such as Figure 6 As shown, the energy-absorbing box 21 is provided with a thinning portion 2121. Specifically, the thinning portion 2121 can be selectively provided on the upper rib 212, the lower rib 213, or the middle rib 214. At least one thinning portion 2121 is provided. The thinning portion 2121 is used to guide the energy-absorbing box 21 to collapse and absorb energy during a collision, thereby improving the collision energy absorption efficiency. By forming a locally weakened area, the thinning portion 2121 causes the energy-absorbing box 21 to fold or bend preferentially along the thinning portion 2121 when the vehicle 200 collides, making the collapse process smoother and more controllable, which can improve the safety performance of the vehicle 200. The thinning portion 2121 can be configured as a groove, a blind hole, a through hole, etc., and this embodiment is not limited to this only type.
[0084] like Figures 8 to 11As shown, specifically, the locking assembly 30 includes a bolt 31, a sleeve 32, and a nut 33. The bolt 31 passes through the main beam 10 and the energy-absorbing box 21. The sleeve 32 is fitted onto the bolt 31. The nut 33 is screwed onto the bolt 31 to lock the energy-absorbing component 20 to the main beam 10. Along the Z-direction, as... Figure 12 As shown, the top plate 13, bottom plate 15, and reinforcing plate 16 of the main beam 10 are all provided with first mounting holes 311, and the upper rib 212, the insertion mating part 211, and the lower rib 213 of the energy-absorbing box 21 are all provided with second mounting holes 312. The first mounting holes 311 of the main beam 10 and the second mounting holes 312 of the energy-absorbing box 21 are provided in a one-to-one correspondence. The sleeve 32 passes through the first mounting holes 311 and the second mounting holes 312. The sleeve 32 can fill the gap between the bolt 31 and the first mounting hole 311 and between the bolt 31 and the second mounting hole 312, and prevent the bolt 31 from being locally worn due to shaking. The sleeve 32 also disperses the locking force of the nut 33 and prevents the edges of the first mounting holes 311 and the second mounting holes 312 from deforming due to stress concentration. The threaded connection between bolt 31 and nut 33 forms a rigid lock, ensuring that the energy-absorbing box 21 is stably and reliably connected to the main beam 10, and enhancing the connection strength of the anti-collision beam assembly 100. Furthermore, the connection method of detachably locking the energy-absorbing component 20 to the main beam 10 using bolts 31, sleeves 32, and nuts 33 facilitates assembly and disassembly and is cost-effective. At least two second mounting holes 312 are spaced apart on the upper rib 212, the plug-in mating part 211, and the lower rib 213; at least two first mounting holes 311 are spaced apart on the top plate 13, the bottom plate 15, and the reinforcing plate 16. The number and position of the first mounting holes 311 correspond to the number and position of the second mounting holes 312.
[0085] The sleeve 32 includes a flange 321 and a cylindrical portion 322. The flange 321 is connected to the end of the cylindrical portion 322. The flange 321 and the cylindrical portion 322 are integrally formed. The sleeve 32 is an aluminum alloy part. The sleeve 32 is integrally formed by aluminum alloy extrusion. The aluminum alloy extrusion process of the sleeve 32 consists of aluminum rod extrusion, profile sawing, aging strengthening, and turning. During installation, the cylindrical portion 322 passes through the main beam 10 and the energy-absorbing box 21 and fits against the bottom plate 15 of the main beam 10. The flange 321 abuts against the upper plate rib 212 to limit the sleeve 32. The bolt 31 passes through the sleeve 32 and is threadedly connected to the nut 33. The bolt 31 presses the flange 321 tightly against the upper plate rib 212. The sleeve 32 can prevent the main beam 10 from being dented due to the bolted connection and improve the connection strength, preventing the preload of the bolt 31 from directly acting on the main beam 10 and causing the main beam 10 to be crushed.
[0086] In some embodiments, the mounting plate 22 is perpendicular to the upper rib 212 and the lower rib 213, and is integrally formed with the upper rib 212 and the lower rib 213. The integral formation of the mounting plate 22 with the upper rib 212 and the lower rib 213 facilitates manufacturing, eliminates welding processes, and eliminates the need to control welding heat deformation, thus improving the assembly efficiency of the anti-collision beam assembly 100 and reducing the long development cycle and production cost of the anti-collision beam assembly 100. The mounting plate 22, together with the upper rib 212 and the lower rib 213, forms a stable right-angle support structure, ensuring that the energy-absorbing component 20 has reliable structural strength and connection strength, and also facilitating the installation of the mounting plate 22 on the main body of the vehicle 200.
[0087] In some embodiments, the top of the mounting plate 22 protrudes from the upper surface of the upper rib 212, and the bottom of the mounting plate 22 protrudes from the lower surface of the lower rib 213. This embodiment increases the contact area between the mounting plate 22 and the main body of the vehicle 200, ensuring that the energy-absorbing component 20 can be stably connected to the main body of the vehicle 200, improving the reliability of the anti-collision beam assembly 100, and ensuring that the vehicle 200 has good safety performance. At the same time, the larger contact area between the mounting plate 22 and the main body of the vehicle 200 can disperse the impact on the main body of the vehicle 200, thereby reducing the degree of damage to the main body of the vehicle 200.
[0088] In some embodiments, such as Figure 3 As shown, the mounting plate 22, upper rib 212, middle rib 214, and lower rib 213 form a cavity 221. At least one reinforcing rib 222 is disposed within the cavity 221. The reinforcing rib 222, together with the mounting plate 22, upper rib 212, middle rib 214, and lower rib 213, forms a multi-directional support structure, which enhances the impact resistance of the energy-absorbing box 21, improves its structural strength, and thus increases the structural strength of the anti-collision beam assembly 100.
[0089] In other embodiments, the reinforcing ribs 222 are multiple pieces, dividing the cavity 221 into multiple grids. These multiple reinforcing ribs 222 support the cavity 221, allowing each grid 2211 to bear a portion of the load when the energy-absorbing box 21 is subjected to a collision, reducing the degree of collapse of the cavity 221. Simultaneously, the mutual restraint between the grids 2211 effectively resists torsional and bending deformation, ensuring that the energy-absorbing box 21 deforms along a preset collapse path, which helps improve the impact resistance of the anti-collision beam assembly 100. The multiple reinforcing ribs 222 increase the transmission path of external impact, allowing the load on the mounting plate 22, upper rib 212, middle rib 214, and lower rib 213 to be more evenly distributed among the ribs, reducing localized stress concentration. Combined with the fastening effect of the locking component 30, this further enhances the reliability of the anti-collision beam assembly 100.
[0090] Exemplarily, in some embodiments, multiple reinforcing ribs 222 are arranged at intervals in the X direction. In some other embodiments, multiple reinforcing ribs 222 are arranged at intervals in the Y direction. In some other embodiments, multiple reinforcing ribs 222 are arranged at intervals in the Z direction. In some other embodiments, at least some of the reinforcing ribs 222 and at least some of the other reinforcing ribs 222 are arranged perpendicular to each other to form a "field" - shaped structure. Preferably, multiple reinforcing ribs 222 are inclined and intersect with each other to form a diamond - shaped grid structure. The diamond - shaped grid structure has stronger tensile and compressive resistance. During a collision, it can uniformly absorb energy through the deformation of the grid 2211, which can improve the impact resistance of the bumper beam assembly 100 and enhance the safety factor of the vehicle 200. In some other embodiments, multiple reinforcing ribs 222 are arranged staggeredly to form multiple small grids of irregular shapes.
[0091] It can be understood that the specific arrangement of multiple reinforcing ribs 222 can be adjusted according to the actual situation and is not specifically limited in this embodiment. As long as it is a deformation method that divides the cavity 221 into multiple grids 2211, it is within the protection scope of this embodiment.
[0092] In some embodiments, at least one weight - reducing hole 223 is provided on the mounting plate 22. On the premise of ensuring the reliable structural strength of the mounting plate 22, the weight - reducing hole 223 can effectively reduce the overall weight of the bumper beam assembly 100, which is in line with the development trend of vehicle 200 lightweight. Specifically, along the thickness direction of the mounting plate 22, the weight - reducing hole 223 can penetrate through the mounting plate 22. The number of weight - reducing holes 223 can be one, two, three, etc.
[0093] In some other embodiments, at least one weight - reducing notch 224 is provided on the mounting plate 22. The weight - reducing notch 224 can also reduce the weight of the mounting plate 22 and the bumper beam assembly 100. Specifically, the weight - reducing notch 224 is provided at the edge of the mounting plate 22. The number of weight - reducing notches 224 can be one, two, three, four, five, etc.
[0094] In some other embodiments, both the weight - reducing hole 223 and the weight - reducing notch 224 are provided on the mounting plate 22 at the same time. The number of both the weight - reducing hole 223 and the weight - reducing notch 224 is at least one.
[0095] In order to connect the mounting plate 22 to the main body of the vehicle 200, in some embodiments, the mounting plate 22 is provided with mounting through holes 225, and screws pass through the mounting through holes 225 to be threadedly connected to the main body of the vehicle 200. Specifically, the mounting through holes 225 are arranged at intervals along the outer periphery of the mounting plate 22. Optionally, the mounting plate 22 in this embodiment can be set as a rectangle, semicircle, circle, polygon, or other irregular shape. This application does not make specific limitations. As long as the deformation mode can realize the connection to the main body of the vehicle 200, it is within the protection scope of this application.
[0096] In some embodiments, at least one of the main beam 10 and the energy-absorbing component 20 is made of aluminum alloy. That is, the main beam 10 can be made of aluminum alloy. The energy-absorbing component 20 can also be made of aluminum alloy. The main beam 10 and the energy-absorbing component 20 can both be made of aluminum alloy. Aluminum alloy has good plasticity and energy absorption properties. When the main beam 10 and the energy-absorbing component 20 collide, they can effectively absorb energy through their own deformation. Combined with the grid 2211 and other structures of the energy-absorbing box 21, the buffering energy absorption effect of the anti-collision beam assembly 100 can be enhanced. At the same time, aluminum alloy has strong corrosion resistance, which can reduce the rust and wear of the anti-collision beam assembly 100 during long-term use and extend the service life of the anti-collision beam assembly 100. In addition, aluminum alloy has excellent processing performance, which makes it easy to accurately process the structure of the main beam 10 and the energy-absorbing component 20 through one-piece molding.
[0097] Specifically, the main beam 10 and the energy-absorbing component 20 can be integrally formed using an aluminum alloy extrusion process, which improves the forming efficiency and structural strength of both the main beam 10 and the energy-absorbing component 20. The aluminum alloy extrusion process consists of aluminum rod extrusion, profile sawing, aging strengthening, and CNC machining or stamping. Aluminum rod extrusion involves placing an aluminum alloy rod heated to a specific temperature into an extrusion die, applying high pressure through an extruder, and causing the aluminum alloy rod to flow and deform within the die cavity. Profile sawing involves precisely sawing the extruded main beam 10 and the energy-absorbing component 20 to remove excess material. Aging strengthening involves aging the sawn profile, causing the precipitation of strengthening phases within the aluminum alloy, thereby improving the mechanical properties (such as tensile strength and hardness) of the main beam 10 and the energy-absorbing component 20, and enhancing structural strength. Subsequently, the aged main beam 10 and the energy-absorbing component 20 are CNC machined or stamped for fine processing to ensure a strong connection between the main beam 10 and the energy-absorbing component 20, allowing the energy-absorbing component 20 to be stably and accurately installed on the main body of the vehicle 200. The energy-absorbing component 20 is extruded along the Y direction.
[0098] Aluminum alloys such as 6-series aluminum profiles can be selected. The main alloying elements of 6-series aluminum profiles are magnesium and silicon. Through heat treatment (aging strengthening), the mechanical properties can be significantly improved, and they have excellent strength, plasticity and machinability.
[0099] In some embodiments, the energy-absorbing components 20 include at least two, which are spaced apart along the length of the main beam 10. The multiple energy-absorbing components 20 can bear the collision load in zones according to the stress distribution of the main beam 10. When the anti-collision beam assembly 100 is subjected to an external impact, each energy-absorbing component 20 can collapse and absorb energy, reducing the damage to the vehicle 200. The spaced-apart energy-absorbing components 20 can disperse the impact to different parts of the main beam 10, reducing local stress concentration. Simultaneously, the multi-point connection between the multiple energy-absorbing components 20 and the main beam 10 enhances the stability and connection strength of the anti-collision beam assembly 100, effectively improving the protective effect and connection reliability of the anti-collision beam assembly 100 on the vehicle 200.
[0100] For example, the energy-absorbing components 20 may include two, four, six, etc., and the energy-absorbing components 20 may be arranged symmetrically about the centerline of the main beam 10.
[0101] According to a second aspect of this application, a collision avoidance system is provided. The collision avoidance system includes a collision avoidance beam assembly 100. Therefore, the collision avoidance system includes all the technical effects of the collision avoidance beam assembly 100 in the above embodiments. Since the technical effects of the collision avoidance beam assembly 100 have been described in detail above, they will not be repeated here.
[0102] According to the third aspect of this application, such as Figure 13 As shown, a vehicle 200 is also provided. The vehicle 200 includes a crash beam assembly 100. Therefore, the vehicle 200 includes all the technical effects of the crash beam assembly 100 in the above embodiments. Since the technical effects of the crash beam assembly 100 have been described in detail above, they will not be repeated here.
[0103] Furthermore, vehicle 200 includes the aforementioned collision avoidance system. Vehicle 200 incorporates all the technical effects of the aforementioned collision avoidance system. The vehicle may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this disclosure does not specifically limit it in this regard.
[0104] As described above, this application discloses a crash beam assembly 100 for automotive lightweighting and passive safety applications. Both the main beam 10 and the energy-absorbing components 20 are made of heat-treatable Al-Mg-Si aluminum alloys, typically 6-series. The crash beam assembly 100 mainly consists of the main beam 10, the energy-absorbing components 20, and the locking assembly 30. The energy-absorbing components 20 and the locking assembly 30 are symmetrically arranged on the main beam 10. Specifically, the energy-absorbing components 20 are screwed onto the main beam 10 via the locking assembly 30.
[0105] The main beam 10 has curvature and is generally symmetrical. Its main process route is: aluminum rod extrusion - profile sawing - profile bending - aging strengthening - CNC machining. Specifically, the extruded cross-section is rectangular, with height h > width w. The main beam 10 consists of a front plate 12, a top plate 13, a rear plate 14, a bottom plate 15, and reinforcing plates 16. The number of reinforcing plates 16 is m (m≥1), and the reinforcing plates 16 are arranged parallel to the top plate 13 and the bottom plate 15 to improve the overall rigidity and strength of the main beam 10. The rear plate 14 is symmetrically provided with insertion slots 111 or insertion holes in the Y direction for nesting with the insertion mating parts 211 at the front end of the energy-absorbing box 21. The shape and number of these slots depend on the shape and number of the insertion mating parts 211 of the energy-absorbing box 21.
[0106] The top plate 13 and the reinforcing plate 16 each have symmetrically arranged first mounting holes 311 in the left and right directions for the sleeve 32 to pass through. The bottom plate 15 has first mounting holes 311 in the left and right directions, which are coaxially arranged to correspond one-to-one with the first mounting holes 311 on the top plate 13 and the reinforcing plate 16, for the bolt 31 to pass through and to limit the bottom of the sleeve 32. The number of first mounting holes 311 (on one side) is n (n≥2). The energy-absorbing box 21, which also serves as the mounting plate 22, is an integral aluminum extrusion part with symmetrical shape on the left and right sides. Its main process route is: aluminum rod extrusion - profile sawing - aging strengthening - CNC machining / stamping. Taking the energy-absorbing box 21 and mounting plate 22 on the right as an example, it consists of two parts: the mounting plate 22 and the energy-absorbing box 21 composed of several stiffeners. The energy-absorbing box 21 is located in front of the mounting plate 22 and is in the shape of a "T". All the stiffeners are perpendicular to the F / AU / D plane of the whole vehicle (F / A refers to the length direction of the vehicle 200, and U / D refers to the height direction of the vehicle 200).
[0107] The mounting plate 22 has mounting through holes 225 at its four corners for bolting to the front and rear longitudinal beams of the vehicle body. The mounting plate 22 has a weight-reducing hole 223 in the center and weight-reducing notches 224 at its edges. The energy-absorbing box 21 mainly consists of an upper rib 212, a lower rib 213, a middle rib 214, and a connecting part 211, all integrally formed. The front ends of the upper rib 212 and lower rib 213 are respectively attached to the top plate 13 and bottom plate 15 of the main beam 10. The middle rib 214, together with the upper rib 212, lower rib 213, and mounting plate 22, forms a cavity 221, which is the main energy-absorbing part of this component. The upper rib 212, lower rib 213, interlocking parts 211, and some intermediate ribs 214 form multiple open cavities, which are the connection parts between this component and the main beam 10 and assist in energy absorption during collisions. The interlocking parts 211 are arranged parallel to the front ends of the upper rib 212 and lower rib 213, and their number is i (i≥1). The front ends of both are partially stripped to match the curvature of the main beam 10. During assembly, the interlocking parts 211 pass through the corresponding mating parts and are nested with the main beam 10. The front ends of the upper rib 212 and the interlocking parts 211 have normal second mounting holes 312 for the sleeve end of the sleeve 32 to pass through and for assembling and limiting the flange of the sleeve 32. The lower rib 213 has normal second mounting holes 312, which correspond one-to-one with the first mounting holes 311 of the main beam 10, for the bolt 31 to pass through and for assembling and limiting the nut 33. The number of second mounting holes 312 (on one side) of the energy-absorbing box 21 is the same as the number of first mounting holes 311 of the main beam 10, both being n (n≥2). Several thinning portions 2121 are provided on the outer sides of the upper slab reinforcement 212 and the lower slab reinforcement 213 to guide the energy-absorbing box 21 to collapse and absorb energy during a collision.
[0108] The locking assembly 30 (double-sided) comprises 2n sets, each consisting of three parts: sleeve 32, bolt 31, and nut 33. The main process route for sleeve 32 is: aluminum rod extrusion – profile sawing – aging hardening – turning. Sleeve 32 consists of a flange 321 and a cylindrical part 322. During assembly, the cylindrical part 322 passes through the first mounting hole 311 of the main beam 10 and the second mounting hole 312 of the energy-absorbing box 21. The lower end face of the cylindrical part 322 is in contact with the bottom plate 15 of the main beam 10, and the lower end face of the flange 321 is in contact with the upper rib 212. Bolt 31 is tightened through sleeve 32, with the bolt 31 flange tightened against the upper end face of the flange 321, and the nut 33 tightened against the lower rib 213. Using sleeve 32 avoids denting of the main beam 10 profile caused by bolted connections and improves connection strength.
