[0035] Next, with reference to the drawings, the anti-collision beam assembly 100 of a vehicle according to an embodiment of the present application will be described.

[0036] As Figures 1 - 5 shown, the anti-collision beam assembly 100 according to an embodiment of the present application includes a beam body 1. The beam body 1 includes a first partition 11, a second partition 12 and a third partition 13 arranged at intervals along a first direction. The first partition 11 and the second partition 12 are adapted to define a first separation cavity 15, and the second partition 12 and the third partition 13 are adapted to define a second separation cavity 14; wherein, the third partition 13 is located on the side of the beam body 1 close to the vehicle body, and the third partition 13 is provided with a protrusion 131, and the protrusion 131 protrudes along the first direction towards the second partition 12.

[0037] Thereby, the structural strength of the third partition 13 can be enhanced to improve the anti-deformation ability of the second separation cavity 14. The second separation cavity 14 is located on the side of the first separation cavity 15 close to the vehicle body, and the second separation cavity 14 can play a certain supporting role after the first separation cavity 15 collapses, thereby improving the protection effect of the anti-collision beam on the vehicle body and meeting the requirements of the overall vehicle safety performance.

[0038] First, as Figure 1As shown, the vehicle includes a bumper beam assembly 100 and a vehicle body. The bumper beam assembly 100 is connected to the vehicle body, such as being connected to the front side or the rear side of the vehicle body. The bumper beam assembly 100 includes a beam main body 1. The beam main body 1 includes a first partition 11, a second partition 12, and a third partition 13. The first partition 11, the second partition 12, and the third partition 13 are arranged at intervals along a first direction, where the first direction is Figure 1 the front-rear direction shown.

[0039] A first separation cavity 15 is defined between the first partition 11 and the second partition 12, and a second separation cavity 14 is defined between the second partition 12 and the third partition 13. The first separation cavity 15 and the second separation cavity 14 are arranged in sequence along the first direction. By providing the first separation cavity 15 and the second separation cavity 14 inside the beam main body 1, when the vehicle encounters a collision, the beam main body 1 can better absorb the impact energy, thereby reducing the impact on the vehicle body.

[0040] Wherein, the third partition 13 is arranged on the side of the beam main body 1 close to the vehicle body, so that the second separation cavity 14 can be located on the side of the first separation cavity 15 close to the vehicle body. The third partition 13 is provided with a protruding portion 131. The protruding portion 131 protrudes along the first direction towards the second partition 12. By providing the protruding portion 131, the third partition 13 can be formed into a corrugated shape to improve the structural strength of the third partition 13, and further improve the anti-deformation ability of the second separation cavity 14.

[0041] It can be understood that when the vehicle collides, the collision object first contacts the first separation cavity 15 and then contacts the second separation cavity 14. The first separation cavity 15 has a good collapse effect and can effectively absorb the collision impact, and the second separation cavity 14 has a good anti-deformation ability and can reduce the impact on the vehicle body, so that the bumper beam assembly 100 can better protect the vehicle body.

[0042] It should be noted that the protruding portion 131 can adopt various specific implementation forms. For example, it can be set that the protruding portion 131 is formed by at least part of the third partition 13 protruding; or, the protruding portion 131 can be set as a reinforcing rib protruding from the third partition 13, and the reinforcing rib can be linear, wavy or a specific shape designed according to mechanical analysis.

[0043] Such as Figure 1 As shown, for the bumper beam assembly 100 according to the embodiment of the present application, by providing the protruding portion 131 on the third partition 13, the structural strength of the third partition 13 can be enhanced to improve the anti-deformation ability of the second separation cavity 14. The second separation cavity 14 is located on the side of the first separation cavity 15 close to the vehicle body. The second separation cavity 14 can play a certain supporting role after the first separation cavity 15 collapses, thereby improving the protection effect of the bumper beam on the vehicle body and meeting the requirements of the vehicle's overall safety performance.

[0044] In some embodiments of the present application, the first partition cavity 15 and / or the second partition cavity 14 may be filled with a foam material. This foam material has good energy absorption performance and can rapidly deform and absorb a large amount of impact energy at the moment of collision. At the same time, the lightweight characteristic of the foam material also ensures that the overall weight of the anti-collision beam assembly 100 will not increase significantly, meeting the requirements of modern automotive lightweight design. The foam material can not only effectively reduce the impact on the passenger compartment during a collision but also, to a certain extent, reduce the repair cost of the vehicle after a collision.

[0045] As Figure 1 shown, in some embodiments of the present application, the beam body 1 adopts an integrated extrusion molding technology. This process can reduce the processing difficulty of the beam body 1 and can ensure the improvement of the structural strength of the beam body 1, enhancing the anti-deformation ability of the beam body 1. In addition, a gap can be provided between the protruding portion 131 and the second partition 12, and the minimum distance between the protruding portion 131 and the second partition 12 is greater than or equal to 8 mm, such as 9 mm, 10 mm, etc., to ensure that the beam body 1 can be extrusion molded.

[0046] As Figure 1 shown, in some embodiments of the present application, a plurality of protruding portions 131 may be provided. The plurality of protruding portions 131 are arranged at intervals in the second direction, the first direction and the second direction are perpendicularly arranged, and the second direction may be Figure 1 the up-and-down direction shown.

[0047] Through the above settings, the plurality of protruding portions 131 can more effectively disperse the impact forces from different directions, so that the impact energy can be absorbed and dispersed in a wider area, thereby reducing the impact on the vehicle body. Moreover, this structural form can enable the beam body 1 to better maintain its shape and integrity when being impacted, which is beneficial to protecting the vehicle body.

[0048] As Figure 1 shown, in some specific embodiments of the present application, the number and spacing of the protruding portions 131 can be adjusted and optimized according to needs to better adapt to different types of collision scenarios and impact angles.

[0049] As Figure 1 shown, in some embodiments of the present application, the spacing between two adjacent protruding portions 131 can be set to be equal to the width of the protruding portion 131, or the spacing between two adjacent protruding portions 131 can be set to be greater than the width of the protruding portion 131.

[0050] Through the above settings, local stress concentration can be avoided, the structural stability of the beam body 1 is improved, thereby enhancing the buffering effect of the beam body 1, and the risk of interference between the protruding portions 131 due to deformation can be reduced, ensuring the stability of the beam body 1 under extreme working conditions.

[0051] Of course, it is also possible to set the distance between two adjacent protruding portions 131 to be less than the width of the protruding portion 131. In this case, it is necessary to avoid direct contact between two adjacent protruding portions 131. The smaller distance enables the entire anti-collision beam assembly 100 to achieve a more compact structural layout while maintaining high energy absorption capacity, which is beneficial for saving space.

[0052] As Figure 1 shown, in some embodiments of the present application, the third partition 13 further includes a plurality of connecting portions 133. The plurality of connecting portions 133 and the plurality of protruding portions 131 are arranged alternately and adjacent connecting portions 133 and protruding portions 131 are connected to each other in pairs. A transition portion is further provided between the protruding portion 131 and the connecting portion 133, and the transition portion can be configured as a transition surface or a transition inclined surface 132. The provision of the transition portion effectively alleviates the possible stress concentration problem between the protruding portion 131 and the connecting portion 133, and improves the overall mechanical properties.

[0053] As Figure 4 shown, further, the transition portion can be configured as a transition inclined surface 132. The included angle between the extending direction of the transition inclined surface 132 and the second direction is α1, satisfying: 45° ≤ α1 ≤ 60°. In a specific embodiment, α1 can be 45°, 50°, 55°, 60°, etc. The included angle of 45° to 60° is a relatively ideal range. This angle range is neither too steep nor too gentle, which can reduce stress concentration and material waste while ensuring structural strength. This design enables the transition inclined surface 132 to withstand a large force without being easily damaged, and this angle range is also convenient for processing and manufacturing, which can not only ensure processing accuracy but also reduce processing difficulty and cost.

[0054] As Figure 1 shown, in some embodiments of the present application, the anti-collision beam assembly 100 further includes: a reinforcing rib 16, the reinforcing rib 16 extends along the first direction, and the reinforcing rib 16 is connected to the inner wall of the first partition cavity 15 and / or the second partition cavity 14.

[0055] Exemplarily, a reinforcing rib 16 can be provided in the first partition cavity 15, and the reinforcing rib 16 is connected to the first partition 11 and extends along the first direction; or, a reinforcing rib 16 can be provided in the first partition cavity 15, and the reinforcing rib 16 is connected to the second partition 12 and extends along the first direction; or, a reinforcing rib 16 can be provided in the second partition cavity 14, and the reinforcing rib 16 is connected to the second partition 12 and extends along the first direction; or, the reinforcing rib 16 can be provided to extend along the first direction and penetrate through the second partition 12, so that a part of the reinforcing rib 16 is located in the first partition cavity 15 and another part is located in the second partition cavity 14.

[0056] It can be understood that the reinforcing rib 16 can provide additional structural support for the bumper beam assembly 100 to improve the structural strength of the bumper beam assembly 100 in the first direction, which helps to enhance the bending strength and torsional stiffness of the bumper beam assembly 100 when subjected to impact force, so that the bumper beam assembly 100 can more effectively absorb and disperse energy during a collision. When a collision occurs, the reinforcing rib 16 can also limit the deformation of the beam body 1 and maintain its shape and integrity, thus playing a more effective anti-collision role.

[0057] Reinforcing ribs 16 can be connected to the inner walls of both the first partition cavity 15 and the second partition cavity 14. This connection method provides higher flexibility and adaptability. According to specific requirements and structural layouts, the reinforcing ribs 16 can be connected to the inner wall of the first partition cavity 15, the second partition cavity 14, or both.

[0058] As Figure 1 shown, in some embodiments of the present application, the reinforcing rib includes a first reinforcing rib 161 and a second reinforcing rib 162. The first reinforcing rib 161 penetrates through the second partition 12 along the first direction and is respectively connected to the first partition 11 and the second partition 12 at both ends. The second reinforcing rib 162 is located in the first partition cavity 15 and is spaced apart from the first reinforcing rib 161. One side of the second reinforcing rib 162 is connected to one of the first partition 11 and the second partition 12.

[0059] It can be understood that the first reinforcing rib 161 is used to further divide the first partition cavity 15 and the second partition cavity 14 into multiple sub-cavities. By subdividing a large space into multiple smaller and more compact sub-cavities, each part can support each other while maintaining independent stability, forming a strength enhancement effect similar to a honeycomb structure and improving the anti-deformation ability of the partition cavity; the second reinforcing rib 162 is used to specifically strengthen the first partition cavity 15 to improve the anti-deformation ability of the first partition cavity 15 and the energy absorption effect of the first partition cavity 15. Moreover, the first reinforcing rib 161 and the second reinforcing rib 162 can achieve a double support effect, greatly optimizing the force-bearing performance of the bumper beam assembly 100.

[0060] In addition, by setting one side of the second reinforcing rib 162 to be connected to one of the first partition 11 and the second partition 12, the forming difficulty of the second reinforcing rib 162 can be reduced, the processing cost can be lowered, and the layout of the second reinforcing rib 162 can be made more flexible, which is conducive to achieving specific strengthening.

[0061] It should be noted that when the second reinforcing ribs 162 are respectively provided on the first partition 11 and the second partition 12, the second reinforcing rib 162 connected to the first partition 11 and the second reinforcing rib 162 connected to the second partition 12 can be arranged in a staggered manner or a facing manner. Thus, a diversified layout can be achieved, which is conducive to meeting the design requirements of the beam body 1.

[0062] Further, as Figure 1 shown, the first reinforcing rib 161 can be disposed at the middle of the beam body 1 along the second direction, and second reinforcing ribs 162 are provided on both sides of the first reinforcing rib 161. Through the above arrangement, the structure of the beam body 1 can be made more uniform, which is beneficial to improving the overall anti-deformation ability of the beam body 1 and enhancing the protection effect of the bumper beam assembly 100 on the vehicle body.

[0063] As Figures 2 - 3 shown, in some embodiments of the present application, the bumper beam assembly 100 of the vehicle further includes: a trailer hitch mounting tube 2. An installation hole penetrating along the first direction is provided on the beam body 1, and the trailer hitch mounting tube 2 is inserted into the installation hole, and the trailer hitch mounting tube 2 is connected to the first reinforcing rib 161. An installation cavity is formed in the trailer hitch mounting tube 2, and the trailer hitch is detachably installed in the installation cavity, such as by screwing.

[0064] Exemplarily, the installation hole can be disposed at the upper part of the first reinforcing rib 161 so that the lower side of the trailer hitch mounting tube 2 can be welded to the first reinforcing rib 161; or, the installation hole can be disposed at the lower part of the first reinforcing rib 161 so that the upper side of the trailer hitch mounting tube 2 can be welded to the first reinforcing rib 161; or, the installation hole can be provided to penetrate the first reinforcing rib 161 along the first direction so that both sides of the trailer hitch mounting tube 2 can be welded to the first reinforcing rib 161 respectively.

[0065] It can be understood that by connecting the trailer hitch mounting tube 2 to the first reinforcing rib 161, the connection between the trailer hitch mounting tube 2 and the beam body 1 can be made more stable, so that the trailer hitch mounting tube 2 can withstand a greater towing force without being easily damaged. In addition, when both sides of the trailer hitch mounting tube 2 are welded to the first reinforcing rib 161 respectively, the installation stability of the trailer hitch mounting tube 2 is better, and the bearing capacity of the trailer hitch mounting tube 2 can be further improved.

[0066] As Figures 1 - 3 shown, in some embodiments of the present application, at least one end of the beam body 1 along the third direction forms an energy absorption area 17. Extension flanges 111 protruding outward are formed on both sides of the first partition 11 along the second direction corresponding to the energy absorption area 17. The extension flanges 111 and the beam body 1 define an energy absorption cavity 171 through a connecting plate 3. The first direction, the second direction and the third direction are perpendicular to each other pairwise. Specifically, the first direction can be Figure 1 the front-back direction shown, the second direction can be Figure 1 the up-down direction shown, and the third direction can be Figure 2 the left-right direction shown.

[0067] For example, energy absorption regions 17 may be formed at one or both ends of the beam body 1 along the third direction. Extension flanges 111 are respectively formed on both sides of the first partition plate 11 along the second direction corresponding to the energy absorption regions 17, and the extension flanges 111 protrude outward along the second direction. The anti-collision beam assembly 100 further includes a connecting plate 3. The connecting plate 3 is located on one side of the extension flange 111 close to the third partition plate 13 along the first direction. One side of the connecting plate 3 is connected to the outer side of the extension flange 111 and the other side is connected to the side wall of the beam body 1 along the second direction. The extension flange 111, the connecting plate 3 and the beam body 1 can jointly define an energy absorption cavity 171, and thus energy absorption cavities 171 are respectively formed on both sides of the energy absorption region 17 along the second direction.

[0068] Through the above arrangement, the energy absorption region 17 can have a better energy absorption effect, so that the anti-collision beam assembly 100 can better protect the vehicle body and improve the safety of the vehicle body.

[0069] It should be noted that the connecting plate 3 and the beam body 1 can be integrally formed or connected by welding. Among them, when the connecting plate 3 and the beam body 1 are integrally formed, their connection is continuous and seamless, avoiding the weld defects and stress concentration problems that may be brought by processing methods such as welding.

[0070] This application also proposes a vehicle.

[0072] In the vehicle according to the embodiment of the present application, by providing a protruding portion 131 on the third partition plate 13, the structural strength of the third partition plate 13 can be enhanced to improve the anti-deformation ability of the second partition cavity 14. The second partition cavity 14 is located on the side of the first partition cavity 15 close to the vehicle body. The second partition cavity 14 can play a certain supporting role after the first partition cavity 15 collapses, thereby improving the protection effect of the anti-collision beam on the vehicle body, meeting the requirements of the overall vehicle safety performance, and improving the user satisfaction.
