The bumper beam assembly generally includes a bumper beam body, two energy absorption units (such as energy absorption boxes), and two mounting plates. The two energy absorption units are respectively fixedly connected to both ends of the bumper beam body. Each energy absorption unit is connected to one mounting plate. The bumper beam assembly is fixedly mounted on the vehicle body component (such as a longitudinal beam) through the two mounting plates.

[0003] When a vehicle collides, the collapse of the energy absorption unit and the deformation of the bumper beam body can effectively absorb the collision energy. However, when a collision occurs, if the connection between the energy absorption unit and the mounting plate fails, or the connection with the bumper beam body fails, the energy absorption unit and the bumper beam body may shift, thus unable to effectively absorb the collision energy, resulting in a reduction in the safety performance of the vehicle.

[0035] The present application provides an anti-collision beam assembly. In one embodiment, as Figures 1 to 4 shown, the anti-collision beam assembly may include an anti-collision beam body 100, two energy absorption units 200 and two mounting plates 300. First connection parts 101 are integrally formed at both ends of the anti-collision beam body 100. The two energy absorption units 200 are respectively connected to both ends of the anti-collision beam body 100. Each energy absorption unit 200 is connected to one end of the anti-collision beam body 100 and the first connection part 101 formed at that end. Each mounting plate 300 is connected to one energy absorption unit 200. And, a second connection part 301 for connecting the energy absorption unit 200 is integrally formed on each mounting plate 300

[0036] Compared with the prior art, the beneficial effects of the bumper beam assembly provided in this embodiment are as follows: a first connecting portion 101 and a second connecting portion 301 are integrally formed on the bumper beam body 100 and the mounting plate 300 respectively. For the bumper beam body 100, the energy absorption unit 200 is not only directly connected thereto, but also connected thereto through the first connecting portion 101, forming a double connection, thereby improving the connection strength. Similarly, for the mounting plate 300, the energy absorption unit 200 is doubly connected thereto through the second connecting portion 301, thereby improving the connection strength. In addition, both the first connecting portion 101 and the second connecting portion 301 are of an integral structure, and the connection strength is higher than that of the split type. When a collision occurs, on the one hand, because the connection strength between the energy absorption unit 200 and the bumper beam body 100 is high and the connection is stable and reliable, the impact force received by the bumper beam body 100 can be effectively transmitted to the energy absorption unit 200, causing the energy absorption unit 200 to collapse and absorb energy. On the other hand, because the connection strength between the energy absorption unit 200 and the mounting plate 300 is high and the connection is stable and reliable, the energy absorption unit 200 and the bumper beam body 100 are firmly fixed to the vehicle body and will not shift, thereby being able to effectively play the function of absorbing collision energy and protecting the safety of the driver and passengers, making the vehicle have good safety performance. In summary, for the bumper beam assembly provided in this embodiment, the energy absorption unit 200 has better connection strength with both the bumper beam body 100 and the mounting plate 300, thus effectively improving the problem of the decline in vehicle safety performance caused by the connection failure between the energy absorption unit 200 and the bumper beam body 100 or the mounting plate 300 in the prior art.

[0037] Generally, for each energy absorption unit 200, its front end is connected to the bumper beam body 100 and the first connecting portion 101, and its rear end is connected to the mounting plate 300 and the second connecting portion 301.

[0038] Optionally, the bumper beam body 100 and the first connecting portion 101 are made by an integral extrusion process.

[0039] Optionally, the mounting plate 300 and the second connecting portion 301 are made by an integral extrusion process.

[0040] Optionally, a plurality of openings are provided on the energy absorption unit 200, which is beneficial for its collapse and energy absorption and weight reduction.

[0041] Optionally, as Figure 6 shown, a reinforcing rib 104 extending along the length direction of itself can be provided inside the bumper beam body 100 to enhance the energy absorption effect of the bumper beam body 100; the reinforcing rib 104 can be an inverted triangle.

[0042] Optionally, the bumper beam assembly provided in this application can be applied to the front of a vehicle.

[0043] In one embodiment, as Figure 3 、Figure 5 and Figure 6 As shown in Figure 6 , the energy absorption unit 200 is connected to the end of the bumper beam body 100 through the connecting plate 400. Optionally, the connecting plate 400 can be fixedly connected to the bumper beam body 100 by bolts and / or welding, and the energy absorption unit 200 can be fixedly connected to the connecting plate 400 by welding.

[0044] In this embodiment, the energy absorption unit 200 is indirectly connected to the bumper beam body 100 through the connecting plate 400 and directly connected to the first connecting portion 101 at the same time.

[0045] In one embodiment, as Figure 3 、 Figure 5 、 Figure 6 and Figure 10 shown, the connecting plate 400 is a long strip-shaped structure extending along the bumper beam body 100, and the cross section of the connecting plate 400 is U-shaped; the connecting plate 400 is embedded in the front part of the energy absorption unit 200, and the connecting plate 400 covers the rear part of the bumper beam body 100.

[0046] This embodiment provides a structure and arrangement form of the connecting plate 400. In this embodiment, the connecting plate 400 is located between the bumper beam body 100 and the energy absorption unit 200. The connecting plate 400 is a long strip-shaped structure, and the dimension in its length direction can cover the energy absorption unit 200. The connecting plate 400 is embedded in the energy absorption unit 200 and its cross section is U-shaped. The outer wall of the connecting plate 400 is attached to the energy absorption unit 200, and the inner wall is attached to the rear part of the bumper beam body 100, so as to partially cover the bumper beam body 100.

[0047] The connecting plate 400 provided in this embodiment can not only connect the energy absorption unit 200 and the bumper beam body 100, but also make the connection structure compact and reliable.

[0048] In one embodiment, as Figures 1 to 3 shown, the second connecting portion 301 is a flange integrally formed on the mounting plate 300, and the second connecting portion 301 is located outside the energy absorption unit 200.

[0049] The second connecting portion 301 being located "outside" the energy absorption unit 200 means that, compared with the energy absorption unit 200, the second connecting portion 301 is closer to the outside of the vehicle. When the energy absorption unit 200 is a square structure, in addition to the "outside", the energy absorption unit 200 generally also has an inner side close to the inside of the vehicle, as well as an upper side and a lower side; in addition, the front end of the energy absorption unit 200 is connected to the bumper beam body 100, and the rear end is connected to the mounting plate 300.

[0050] Compared with other positions, the second connecting portion 301 is more conducive to improving the connection strength between the energy absorption unit 200 and the mounting plate 300 in the case of a frontal offset collision on the outside of the energy absorption unit 200. "Frontal offset collision" means that when a frontal collision occurs, the collision part is close to one end of the anti-collision beam body 100, rather than in the middle thereof. In the case of a frontal offset collision, the anti-collision beam body 100 and the energy absorption unit 200 at the collision part collapse towards the inside of the vehicle; while for the end of the anti-collision beam body 100 away from the collision part, under the action of the collision force, a torque is formed with the collision part as the center of the circle, and this torque causes the end (far end) of the anti-collision beam body 100 and the energy absorption unit 200 fixed to this end to have a tendency to move towards the outside of the vehicle; at this time, if the connection strength between the energy absorption unit 200 and the mounting plate 300 is insufficient, it may lead to connection failure; for example, the mounting plate is disengaged from the energy absorption unit, or the mounting plate is torn. When a frontal offset collision occurs, for the end far from the collision, the farther away from the collision part (i.e., the closer to the outside of the vehicle), the greater the torque that causes the connection between the energy absorption unit 200 and the mounting plate 300 to fail; because the farther away from the collision part, the larger the radius for generating the torque; the torque is the product of the collision force and the radius, and when the collision force is constant, the larger the radius, the greater the torque. In this embodiment, the second connecting portion 301 is located on the outside of the energy absorption unit 200, strengthening the connection strength between the outermost end of the collision, the energy absorption unit 200 and the mounting plate 300, thereby effectively improving the problem of connection failure between the energy absorption unit 200 and the mounting plate 300 in the case of a frontal offset collision.

[0051] Optionally, the structure provided in this embodiment can be applied to the working conditions of a test vehicle and a mobile progressive deformation obstacle for a 50% frontal overlap offset collision; the collision speed is not limited, for example, it can be km / h.

[0052] In this embodiment, the second connecting portion 301 is a flanging structure, with a simple shape, easy to connect, and convenient for manufacturing; optionally, the mounting plate 300 with a flange provided in this embodiment can be manufactured by an integral extrusion process.

[0053] In one embodiment, both the mounting plate 300 and the second connecting portion 301 are welded to the energy absorption unit 200. Optionally, as Figure 7 shown, a first weld seam 302 (i.e., the thick black line in the figure) is formed by welding. The first weld seam 302 simultaneously realizes the connection between the mounting plate 300 and the energy absorption unit 200, and the connection between the second connecting portion 301 and the energy absorption unit 200. The second connecting portion 301 is attached to the outer side surface of the energy absorption unit 200, and the first weld seam 302 can be formed by one-time welding.

[0054] Optionally, the welding can be MIG welding (Metal Inert Gas Welding).

[0055] In one embodiment, the second connecting portion 301 is bolted to the energy absorption unit 200. Optionally, as Figure 7 shown, the second connecting portion 301 can be connected to the energy absorption unit 200 by two bolts 303; as Figure 8 shown, two rivet nuts 201 can be provided on the energy absorption unit 200 to cooperate with the bolts 303 to realize the connection between the second connecting portion 301 and the energy absorption unit 200.

[0056] In one embodiment, both the mounting plate 300 and the second connecting portion 301 are welded to the energy absorption unit 200, and the second connecting portion 301 is bolted to the energy absorption unit 200.

[0057] Optionally, during the manufacturing process, the mounting plate 300 and the energy absorption unit 200 can be tightly connected and assembled by bolts 303 first, and then fully welded by MIG welding to achieve double fixation, thus effectively solving the problem of connection failure between the outer side of the mounting plate 300 and the energy absorption unit 200.

[0058] In one embodiment, as Figures 1 to 3 shown, the first connecting portion 101 includes an upwardly extending flanging 102 and a downwardly extending flanging 103.

[0059] In this embodiment, the end of the bumper beam body 100 is formed with an upwardly extending flanging 102 and a downwardly extending flanging 103 respectively. Compared with the structure without the upper and lower flangings, the end of the bumper beam body 100 provided in this embodiment has a larger Z-direction (i.e., up and down direction) dimension, so that the energy absorption unit 200 with a larger Z-direction dimension can be connected. Optionally, as Figures 1 to 3 shown, the upper surface of the energy absorption unit 200 is substantially flush with the upper edge of the flanging 102, and the lower surface of the energy absorption unit 200 is substantially flush with the lower edge of the flanging 103; in this way, the energy absorption unit 200 has a larger Z-direction dimension and thus a larger volume, so as to be able to absorb more collision energy.

[0060] Optionally, in this embodiment, the Z-direction dimension of the energy absorption unit 200 is substantially the same as the Z-direction dimension of the vehicle longitudinal beam, and their upper and lower surfaces are also substantially flush.

[0061] As Figure 1 and Figure 2 shown, in this embodiment, the upper and lower flangings are only formed at the left and right ends of the bumper beam body 100, and there is no flanging and a gap is left in the middle of the bumper beam body 100, which is beneficial to heat dissipation and air intake.

[0062] Optionally, both the upwardly extending flanging 102 and the downwardly extending flanging 103 are formed by an integral extrusion process.

[0063] In one embodiment, both the first connecting portion 101 and the bumper beam body 100 are welded to the energy absorption unit 200, and the formed weld seams are as shown in Figure 9 the thick black lines. The second weld seam 501 is a horizontal weld seam connecting the upper edge of the energy absorption unit 200 and the surface of the upward flanging 102. The third weld seam 502 is a vertical weld seam connecting the outer edge of the energy absorption unit 200 and the surface of the upward flanging 102. The fourth weld seam 503 is a vertical weld seam connecting the outer edge of the energy absorption unit 200 and the connecting plate 400. The fifth weld seam 504 is a vertical weld seam connecting the bumper beam body 100 and the connecting plate 400. The sixth weld seam 505 is a vertical weld seam connecting the outer edge of the energy absorption unit 200 and the downward flanging 103. The seventh weld seam 506 is a horizontal weld seam connecting the lower edge of the energy absorption unit 200 and the surface of the downward flanging 103. Among them, the second weld seam 501, the third weld seam 502, the fourth weld seam 503, the sixth weld seam 505, and the seventh weld seam 506 can be formed by one-time welding.

[0064] Optionally, the welding can be MIG welding.

[0065] In one embodiment, as shown in Figure 7 and Figure 8 , the energy absorption unit 200 is an energy absorption box, and the energy absorption box has an outer cavity 202 and an inner cavity 203; compared with the inner cavity 203, the outer cavity 202 is more likely to collapse and absorb energy; thus, when a small overlap collision occurs, the outer cavity 202 can quickly absorb the collision energy and improve the safety performance of the vehicle.

[0066] Specifically, in order to make the outer cavity 202 more likely to collapse and absorb energy than the inner cavity 203, different structural strengths can be set for the two cavities. Optionally, the following technical means can be used to set different structural strengths for the two cavities: reinforcing ribs can be arranged in the inner cavity 203, and no reinforcing ribs are arranged in the outer cavity 202; or, when the wall thicknesses of the two cavities are the same, the volume of the outer cavity is made larger than that of the inner cavity; or, when the volumes of the two cavities are the same, the wall thickness of the inner cavity is made larger than that of the outer cavity.

[0067] In one embodiment, the bumper beam body 100 is provided with a trailer hook connecting member 105, as shown in Figure 1 and Figure 2 ; the trailer hook connecting member 105 extends into the inner cavity 203 of the energy absorption box, and a reinforcing plate 204 is arranged in the inner cavity 203.

[0068] Arranging the reinforcing plate 204 can improve the structural strength of the inner cavity 203. Optionally, as shown in Figure 7 and Figure 8 , the reinforcing plate 204 is arranged horizontally, and the number of the reinforcing plates 204 is two and they are distributed vertically.

[0069] In this embodiment, the trailer hitch connecting member 105 is closer to the inner cavity 203 than the outer cavity 202. The inner cavity 203 has higher structural strength, so that the trailer hitch connecting member 105 has higher installation strength. Optionally, the trailer hitch connecting member 105 may be a trailer hitch nut tube.

[0070] In one embodiment, as Figure 3 , Figure 7 and Figure 8 shown, a groove 205 is provided at the front part of the energy absorption unit 200, and the anti-collision beam body 100 is embedded in the groove 205. Specifically, as Figure 7 and Figure 8 shown, the groove 205 runs through the energy absorption unit 200 in the horizontal direction.

[0071] The edge of the groove 205 can be welded to connect the anti-collision beam body 100 or the connecting plate 400. Compared with not providing the groove 205, providing the groove 205 can increase the weld length, thereby improving the connection strength between the energy absorption unit 200 and the anti-collision beam body 100. In addition, by providing the groove 205, the front part of the energy absorption unit 200 can perfectly fit the shape of the end of the anti-collision beam body 100 with upper and lower flanges, making the connection between the energy absorption unit 200 and the anti-collision beam body 100 compact and reliable.

[0072] On the other hand, the present application also provides a vehicle, which has the above anti-collision beam assembly, and there is higher connection strength between the energy absorption unit of the anti-collision beam assembly and the mounting plate as well as between the energy absorption unit and the anti-collision beam body. Compared with other vehicles in the prior art, when a collision occurs, the anti-collision beam assembly of the vehicle provided by the present application can better play the function of absorbing collision energy and protecting the driver and passengers, so that the vehicle has better safety performance.

[0073] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
