[0030] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] Reference below Figures 1-6 The anti-collision beam assembly 100 according to the first embodiment of the present invention is described.

[0032] like Figure 1-Figure 3 As shown, the anti-collision beam assembly 100 according to the embodiment of the first aspect of the present utility model includes an anti-collision beam body 10.

[0033] The anti-collision beam body 10 includes a front plate 11, a top plate 12 and a bottom plate 13. The front plate 11 extends left and right, the top plate 12 is connected to the upper end of the front plate 11 and extends backward, and the bottom plate 13 is connected to the lower end of the front plate 11 and extends backward, wherein the rear end of the top plate 12 is formed with a first folded edge 14 extending downward, and / or the rear end of the bottom plate 13 is formed with a second folded edge 15 extending upward.

[0034] For example Figure 1-Figure 3 As shown, the front plate 11 is arranged at the front side of the anti-collision beam body 10 and the front plate 11 extends along the left and right directions of the vehicle. Figure 1 and Figure 3 As shown, the top plate 12 is a rectangular plate, which is arranged on the upper side of the front plate 11 and extends in the left-right direction of the vehicle. The bottom plate 13 is a rectangular plate, which is arranged on the lower side of the front plate 11 and extends in the left-right direction of the vehicle.

[0035] Specifically, the upper end of the front panel 11 is connected to the front end of the top panel 12, and the lower end of the front panel 11 is connected to the front end of the bottom panel 13. Furthermore, the front panel 11 can be arranged vertically, and the top panel 12 and the bottom panel 13 can be arranged horizontally, that is, the front panel 11 is perpendicular to the top panel 12 and the front panel 11 is perpendicular to the bottom panel 13.

[0036] For example, the rear end of the top plate 12 is formed with a first folded edge 14 extending downward; another example, the rear end of the bottom plate 13 is formed with a second folded edge 15 extending upward; another example, the rear end of the top plate 12 is formed with a first folded edge 14 extending downward, and the rear end of the bottom plate 13 is formed with a second folded edge 15 extending upward. Preferably, the front plate 11, top plate 12, and bottom plate 13 of the anti-collision beam body 10 can have the same wall thickness.

[0037] In a specific example, Figure 1 and Figure 3As shown, the first folding edge 14 is a rectangular plate, which is arranged on the lower side of the top plate 12 and extends in the left-right direction of the vehicle. The second folding edge 15 is a rectangular plate, which is arranged on the upper side of the bottom plate 13 and extends in the left-right direction of the vehicle.

[0038] Specifically, the rear end of the top plate 12 is connected to the upper end of the first fold 14, and the rear end of the bottom plate 13 is connected to the lower end of the second fold 15. Furthermore, the first fold 14 and the second fold 15 can be arranged vertically, that is, the top plate 12 is perpendicular to the first fold 14 and the bottom plate 13 is perpendicular to the second fold 15.

[0039] In this embodiment, when the anti-collision beam assembly 100 is involved in a collision, the front plate 11 of the anti-collision beam body 10 deforms due to the collision force and effectively transfers the energy generated by the collision to the top plate 12 and the bottom plate 13. The top plate 12 and the bottom plate 13 can effectively absorb the energy generated by the collision through deformation and further transfer the energy to the first folding edge 14 and the second folding edge 15. The first folding edge 14 and the second folding edge 15 can absorb the energy generated by the collision through deformation, thereby helping to disperse the collision force and guide the transmission direction of the collision force, thereby effectively controlling deformation. Therefore, the first folding edge 14 and the second folding edge 15 can effectively increase the stiffness and strength of the edge area of the top plate 12 or the bottom plate 13.

[0040] As a result, the anti-collision beam body 10 can effectively improve the structural strength and rigidity of the anti-collision beam assembly 100, thereby effectively improving the anti-collision performance of the anti-collision beam assembly 100 and further effectively improving the protective effect of the anti-collision beam assembly 100. In addition, the front plate 11, top plate 12, and bottom plate 13 of the anti-collision beam body 10 have a simple structure and are easy to produce and process, which can effectively reduce the manufacturing difficulty, save labor hours, and thus effectively reduce costs.

[0041] According to the anti-collision beam assembly 100 of the embodiment of the present invention, an anti-collision beam body 10 is set, and the anti-collision beam body 10 includes a front plate 11, a top plate 12 and a bottom plate 13. The front plate 11 extends left and right, the top plate 12 is connected to the upper end of the front plate 11 and extends backward, and the bottom plate 13 is connected to the lower end of the front plate 11 and extends backward, wherein the rear end of the top plate 12 is formed with a first folding edge 14 extending downward, and / or the rear end of the bottom plate 13 is formed with a second folding edge 15 extending upward, which can not only effectively improve the strength and rigidity of the anti-collision beam assembly 100, thereby effectively improving the anti-collision performance and safety performance of the anti-collision beam assembly 100, but also can simplify the structure of the anti-collision beam assembly 100, thereby effectively reducing the processing difficulty of the anti-collision beam assembly 100, and thus effectively saving costs.

[0042] Preferably, the front plate 11, the top plate 12 and the bottom plate 13 can be made of aluminum alloy. Aluminum alloy has the advantages of light weight and easy processing. Therefore, it can effectively reduce the weight of the anti-collision beam body 10, facilitate the processing of the anti-collision beam body 10, save labor time and reduce costs. It should be noted that aluminum alloy is an alloy material based on aluminum with one or more alloying elements added. By adding different alloying elements, the mechanical properties of aluminum can be significantly improved, such as improving strength, hardness and wear resistance, while maintaining its advantages of light weight and corrosion resistance. Generally speaking, aluminum alloy has the advantages of high specific strength, light weight, low cost, easy processing, corrosion resistance and recyclability.

[0043] Preferably, the anti-collision beam body 10 can be manufactured using an aluminum alloy extrusion process. This process involves extruding a solid or hollow metal blank through a die under high temperature and high pressure. This process offers advantages such as a simple process flow, high production efficiency, and low mold costs. The anti-collision beam body 10 manufactured using this extrusion process exhibits excellent bending resistance and impact resistance.

[0044] In one embodiment of the present invention, Figure 3 As shown, the first folded edge 14 and the second folded edge 15 cooperate to define an opening 101. In the vertical direction, the ratio of the width of the opening 101 to the height of the anti-collision beam body 10 is greater than or equal to 1 / 3 and less than or equal to 1 / 2. For example, in the vertical direction, the ratio of the width of the opening 101 to the height of the anti-collision beam body 10 can be 1 / 3, 3 / 8, 5 / 12, 11 / 24, and 1 / 2.

[0045] In this embodiment, the opening 101 is defined by cooperating the first folding edge 14 and the second folding edge 15. In the up and down directions, the ratio of the width of the opening 101 to the height of the anti-collision beam body 10 is greater than or equal to 1 / 3 and less than or equal to 1 / 2, thereby ensuring that the anti-collision beam body 10 can maintain sufficient strength and good energy absorption characteristics while effectively reducing the amount of material used, thereby effectively reducing the weight of the anti-collision beam body 10.

[0046] In one embodiment of the present invention, Figure 3 As shown, a reinforcement portion 111 is formed on the front panel 11. The reinforcement portion 111 is formed by a portion of the front panel 11 protruding forward or backward. The reinforcement portion 111 extends left and right, and its ends extend to the left and right end edges of the front panel 11. For example, the number of reinforcement portions 111 can be one; for another example, the number of reinforcement portions 111 can be multiple, for example, the number of reinforcement portions 111 can be two, three, four, five, or more than six.

[0047] When the anti-collision beam body 10 is involved in a collision, the reinforcement 111 on the front plate 11 enables the front plate 11 to better resist deformation during impact, thereby helping to optimize the energy absorption characteristics of the anti-collision beam body 10. During a collision, the reinforcement 111 can absorb some of the collision energy through its own deformation, thereby reducing the energy transferred to other parts of the vehicle.

[0048] In this embodiment, a reinforcement portion 111 is provided on the front plate 11. The reinforcement portion 111 is formed by a portion of the front plate 11 protruding forward or backward. The reinforcement portion 111 extends left and right, and both ends extend to the left and right end edges of the front plate 11 respectively. This can effectively increase the local rigidity and overall stability of the front plate 11, thereby effectively improving the anti-collision effect of the anti-collision beam body 10.

[0049] In one embodiment of the present invention, Figure 3 As shown, the reinforcement portion 111 is formed by protruding backward from the front plate 11 , and the height of the reinforcement portion 111 in the up-down direction gradually decreases from the front to the back.

[0050] In a specific example, Figure 3 As shown, the reinforcement portion 111 is formed by protruding backward from the middle part of the front plate 11 in the up and down directions, and the length of the reinforcement portion 111 in the left and right directions is consistent with the front plate 11, thereby further optimizing the structural structure of the front plate 11, thereby effectively saving the installation space of the anti-collision beam body 10.

[0051] Specifically, the reinforcement portion 111 is provided with a first reinforcement plate 1111, a second reinforcement plate 1112 and a third reinforcement plate 1113. Figure 3 As shown, the first reinforcing plate 1111 and the second reinforcing plate 1112 are arranged at an angle and the first reinforcing plate 1111 and the second reinforcing plate 1112 are arranged symmetrically in the up and down directions, and the third reinforcing plate 1113 is arranged between the first reinforcing plate 1111 and the second reinforcing plate 1112. Further, the third reinforcing plate 1113 is arranged vertically, the upper end of the third reinforcing plate 1113 is connected to the first reinforcing plate 1111, and the lower end of the third reinforcing plate 1113 is connected to the second reinforcing plate 1112.

[0052] In this embodiment, the reinforcement portion 111 is formed by protruding backward from the front plate 11. As the height of the reinforcement portion 111 decreases from front to back, the reinforcement portion 111 can evenly absorb the energy generated by the collision when the front plate 11 of the anti-collision beam body 10 is involved in a collision, thereby preventing stress concentration and effectively protecting the front plate 11 and improving the protective performance. Furthermore, the reinforcement portion 111 can save material and effectively reduce the weight of the front plate 11.

[0053] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the reinforcement portion 111 is opposite to the opening 101 in the front-to-rear direction, and the ratio of the width of one end of the reinforcement portion 111 facing the opening 101 in the up-down direction to the height of the anti-collision beam body 10 in the up-down direction is greater than or equal to 1 / 3 and less than or equal to 1 / 2.

[0054] For example, the ratio of the width of the end of the reinforcement portion 111 toward the opening 101 in the vertical direction to the height of the anti-collision beam body 10 in the vertical direction can be 1 / 3, 3 / 8, 5 / 12, 11 / 24 and 1 / 2. Figure 1 As shown, the width of the third reinforcing plate 1113 of the front plate 11 in the up-down direction is consistent with the width of the opening 101 in the up-down direction.

[0055] This embodiment optimizes the structural construction of the anti-collision beam body 10 by setting the reinforcement part 111 to be opposite to the opening 101 in the front-to-back direction, helps to guide the path transmission of the collision force, and provides sufficient deformation space for the deformation of the reinforcement part 111, thereby effectively ensuring the effect of the reinforcement part 111 in absorbing the collision energy; by setting the ratio of the width of one end of the reinforcement part 111 facing the opening 101 in the up-down direction to be greater than or equal to 1 / 3 and less than or equal to 1 / 2 of the height of the anti-collision beam body 10 in the up-down direction, the size of the reinforcement part 111 can be effectively guaranteed, and thus effectively ensuring that the reinforcement part 111 has sufficient strength and rigidity to resist the collision force.

[0056] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the anti-collision beam assembly 100 also includes: an energy absorption box 20, which is arranged on the rear side of the anti-collision beam body 10 and fixedly connected to the anti-collision beam body 10, and the energy absorption box 20 includes a box body and a limiting portion 25 connected to the front side of the box body, the limiting portion 25 extends into the anti-collision beam body 10, and the height of the limiting portion 25 in the up and down direction is greater than the width of the opening 101 in the up and down direction.

[0057] When the anti-collision beam assembly 100 is involved in a collision, the anti-collision beam body 10 resists the collision force by deforming and transferring the collision energy to the energy absorption box 20. The energy absorption box 20 absorbs the collision energy by deforming or breaking, effectively dissipating the collision force. In addition, the stopper 25 on the front side of the box body effectively reduces the displacement between the energy absorption box 20 and the anti-collision beam body 10 during a collision, thereby effectively reducing the risk of tearing of the anti-collision beam assembly 100 during a collision.

[0058] Furthermore, the strength and rigidity of the anti-collision beam body 10 are greater than those of the energy absorption box 20. Therefore, in the event of a collision, the energy absorption box 20 can effectively absorb the energy generated by the collision, preventing damage caused by excessive deformation of the anti-collision beam body 10, thereby effectively ensuring the integrity of the anti-collision beam body 10 and thus ensuring the protective effect. Preferably, the energy absorption box 20 can be made of aluminum alloy and can be manufactured using an aluminum alloy extrusion molding process.

[0059] In this embodiment, an energy absorption box 20 is provided in the anti-collision beam assembly 100. The energy absorption box 20 is arranged on the rear side of the anti-collision beam body 10 and is fixedly connected to the anti-collision beam body 10, which can effectively disperse the collision force, thereby effectively improving the safety performance of the anti-collision beam assembly 100 when a collision occurs; a box body and a limiting portion 25 connected to the front side of the box body are provided in the energy absorption box 20, the limiting portion 25 extends into the anti-collision beam body 10, and the height of the limiting portion 25 in the up and down direction is greater than the width of the opening 101 in the up and down direction, which can provide additional support for the anti-collision beam body 10, reduce the occurrence of tearing of the anti-collision beam assembly 100 during a collision, thereby effectively ensuring the structural integrity of the anti-collision beam assembly 100 during a collision.

[0060] In one embodiment of the present invention, Figure 4-Figure 6 As shown, the energy absorption box 20 has two side plates 21 arranged opposite to each other in the left-right direction, and there are two limiting portions 25 formed in a plate shape extending forward and backward. The two limiting portions 25 are respectively connected to the front sides of the two side plates 21.

[0061] In a specific example, Figure 4-Figure 6 As shown, the crash box 20 also has two third connecting plates 22 arranged opposite each other in the vertical direction. The two third connecting plates 22 are spaced apart in the vertical direction. The left and right ends of one third connecting plate 22 are respectively connected to the upper ends of the two side plates 21, while the left and right ends of the other third connecting plate 22 are respectively connected to the lower ends of the two side plates 21. Furthermore, the two third connecting plates 22 are arranged horizontally, and the two side plates 21 are arranged vertically. The limiting portion 25 is a rectangular plate. The third connecting plates 22 and the side plates 21 are provided with guiding grooves 23. In the event of a collision, the guiding grooves 23 can guide the crash box 20 to deform according to a preset target, thereby effectively improving the reliability of the deformation.

[0062] This embodiment provides two side panels 21 arranged opposite each other in the left and right directions of the crash box 20. Two stoppers 25 are provided, each formed in the shape of a plate extending forward and backward. The two stoppers 25 are connected to the front sides of the two side panels 21, respectively. This allows the crash box 20 to have multiple deformation zones, thereby effectively improving the energy absorption efficiency of the crash box 20 during a collision and preventing excessive deformation of the anti-collision beam, thereby effectively ensuring the crash prevention effect. Furthermore, the structure of the crash box 20 can be effectively simplified, reducing the difficulty of manufacturing the crash box 20.

[0063] In one embodiment of the present invention, Figure 5 As shown, the upper edge of the limiting portion 25 is formed with a downwardly concave first groove 201, and the lower end of the first folded edge 14 is engaged in the first groove 201. The lower edge of the limiting portion 25 is formed with an upwardly concave second groove 202, and the upper end of the second folded edge 15 is engaged in the second groove 202.

[0064] Specifically, the width of the first groove 201 in the front-to-back direction can be consistent with the wall thickness of the first fold 14, thereby enabling the side walls of the first groove 201 in the front-to-back direction to be closely attached to the first fold 14. The width of the second groove 202 in the front-to-back direction can be consistent with the wall thickness of the second fold 15, thereby enabling the side walls of the second groove 202 in the front-to-back direction to be closely attached to the second fold 15. Furthermore, the height of the first groove 201 and the second groove 202 in the vertical direction is greater than or equal to 5 mm and less than or equal to 25 mm, thereby effectively ensuring the limiting effect of the limiting portion 25 and saving material.

[0065] In this embodiment, a downwardly concave first groove 201 is formed on the upper edge of the limiting portion 25, and the lower end of the first folded edge 14 is engaged in the first groove 201. A second upwardly concave groove 202 is formed on the lower edge of the limiting portion 25, and the upper end of the second folded edge 15 is engaged in the second groove 202. This can not only effectively ensure the limiting effect of the limiting portion 25, thereby effectively improving the reliability of the anti-collision beam assembly 100 when a collision occurs, but also effectively simplify the structural construction of the limiting portion 25.

[0066] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the limiting portion 25 is welded to the inner wall of the anti-collision beam body 10 , and the box body is welded to the first folded edge 14 and the second folded edge 15 .

[0067] In a specific example, Figure 1 and Figure 2As shown, the front end of the limiting portion 25 is welded to the side of the third reinforcing plate 1113 of the reinforcing portion 111 that faces the opening 101, and the two third connecting plates 22 of the energy absorption box 20 are respectively welded to the first folded edge 14 and the second folded edge 15. Furthermore, the two side plates 21 of the energy absorption box 20 are both welded to the first folded edge 14 and the second folded edge 15.

[0068] In this embodiment, the limiting portion 25 is welded to the inner wall of the anti-collision beam body 10, and the box body is welded to the first folded edge 14 and the second folded edge 15, which can effectively improve the structural strength and rigidity of the connection between the energy absorption box 20 and the anti-collision beam body 10, thereby effectively enhancing the stability and integrity of the anti-collision beam assembly 100 during a collision.

[0069] In one embodiment of the present invention, Figure 2 As shown, in the direction from the left and right ends of the anti-collision beam body 10 toward the middle, the anti-collision beam body 10 protrudes forward, and there are two energy absorption boxes 20, which are respectively connected to the left and right ends of the anti-collision beam body 10, wherein, in the direction from the left and right ends of the anti-collision beam body 10 toward the middle, the front end surface of the box body is an inclined surface extending forward.

[0070] It should be noted that when installing the energy absorption box 20 in the anti-collision beam assembly 100, first install the limiting portion 25 of the energy absorption box 20 from one end of the anti-collision beam body 10 in the left and right directions into the interior of the anti-collision beam body 10, then move the energy absorption box 20 to the predetermined installation position, and then adjust the position of the energy absorption box 20, and weld the energy absorption box 20 to the anti-collision beam body 10.

[0071] In a specific example, Figure 2 As shown, the central region of the anti-collision beam body 10 in the left-right direction is convex forward, and the anti-collision beam body 10 is bilaterally symmetrical, which effectively increases the length of the anti-collision beam body 10 and effectively increases the deformation space of the convex region of the anti-collision beam body 10. Furthermore, the two energy absorption boxes 20 are arranged bilaterally symmetrically, which can effectively improve the energy absorption effect of the energy absorption boxes 20 in different types of collisions.

[0072] In this embodiment, the anti-collision beam body 10 is protruded forward in the direction from the left and right ends of the anti-collision beam body 10 toward the middle, and the number of energy absorption boxes 20 is set to two. The two energy absorption boxes 20 are respectively connected to the left and right ends of the anti-collision beam body 10, which can effectively improve the energy absorption effect of the anti-collision beam body 10 and the energy absorption box 20, thereby effectively ensuring the protection effect of the anti-collision beam assembly 100; in the direction from the left and right ends of the anti-collision beam body 10 toward the middle, the front end surface of the box body is set to an inclined surface extending forward, which not only enables the box body to fit tightly with the anti-collision beam body 10, but also enables the two limiting parts 25 of the energy absorption box 20 to be non-coplanar with the connection position of the anti-collision beam body 10, thereby effectively ensuring the connection effect.

[0073] In one embodiment of the present invention, Figure 4 As shown, a reinforcing plate 24 is provided within the box body, connected between two side walls of the box body that are opposite in the left-right direction and / or the up-down direction. The number of reinforcing plates 24 can be one or more, for example, two, three, four, five, or six or more. Furthermore, the plurality of reinforcing plates 24 can be arranged parallel to each other and spaced apart.

[0074] For example, the reinforcing plate 24 is connected between the two side walls of the box body that are opposite in the left-right direction; for another example, the reinforcing plate 24 is connected between the two side walls of the box body that are opposite in the up-down direction; for another example, a portion of the reinforcing plates 24 is connected between the two side walls of the box body that are opposite in the left-right direction and another portion of the reinforcing plates 24 is connected between the two side walls of the box body that are opposite in the up-down direction. In a specific example, Figure 4 As shown, there is only one reinforcing plate 24, and the reinforcing plate 24 is connected between two side walls of the box body that are opposite to each other in the up and down directions.

[0075] This embodiment provides a reinforcing plate 24 inside the box body, and the reinforcing plate 24 is connected between the two side walls of the box body that are opposite to each other in the left-right direction and / or the up-down direction. This can effectively improve the structural strength and rigidity of the energy absorption box 20, thereby effectively improving the energy absorption effect of the energy absorption box 20 when a collision occurs, and further effectively improving the protection effect of the anti-collision beam body 10.

Furthermore, the anti-collision beam assembly 100 and the front longitudinal beam can be connected by bolts.

[0077] According to the vehicle of the embodiment of the present invention, by setting the anti-collision beam assembly 100 of the above-mentioned first aspect embodiment, not only can the strength and rigidity of the anti-collision beam assembly 100 be effectively improved, thereby effectively improving the anti-collision performance and safety performance of the anti-collision beam assembly 100, but also the structure of the anti-collision beam assembly 100 can be simplified, thereby effectively reducing the processing difficulty of the anti-collision beam assembly 100, and thus effectively saving costs.
