[0031] The utility model discloses an anti-collision beam, which simplifies the structure while ensuring the performance of the anti-collision beam. In addition, the utility model also discloses a vehicle with the anti-collision beam.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0034] like Figure 1 As shown, the present application discloses an anti-collision beam, comprising: an anti-collision beam body 100 , an anti-collision beam mounting plate 200 and an energy absorbing assembly 300 .

[0035] The anti-collision beam body 100 is the main structure of the anti-collision beam. When a vehicle collides, the anti-collision beam body 100 can absorb the collision energy. The shape, size and material of the anti-collision beam body 100 can refer to the main structure of the existing anti-collision beam and are not specifically limited here.

[0036] The anti-collision beam mounting plate 200 is used to mount the anti-collision beam body 100 on the vehicle body. The structure of the anti-collision beam mounting plate 200 includes but is not limited to a rectangular plate.

[0037] The energy absorbing assembly 300 is connected between the anti-collision beam body 100 and the anti-collision beam mounting plate 200 and is used to absorb collision energy when the vehicle collides.

[0038] The number of the energy absorbing components 300 includes but is not limited to two. In some embodiments, the energy absorbing components 300 and the anti-collision beam mounting plates 200 are arranged in a one-to-one correspondence.

[0039] In some embodiments, the anti-collision beam body 100 is an arc-shaped plate, and both ends of the anti-collision beam body 100 are respectively mounted on the vehicle body through the anti-collision beam mounting plate 200. In some embodiments, the anti-collision beam body 100 is a symmetrical structure along the length direction, and the energy absorbing assembly 300 is arranged at both ends of the anti-collision beam body 100 in the length direction, and is symmetrically arranged along the length direction of the anti-collision beam body 100.

[0040] like Figures 2 to 5 As shown, the energy absorbing assembly 300 includes an energy absorbing box 301 , an energy absorbing block 302 and an elastic sealing member 303 .

[0041] Among them, the energy absorbing block 302 is a foam aluminum energy absorbing block, which is arranged on the outside of the energy absorbing box 301, and there is a collapse gap between the energy absorbing box 301 and the circumferential side wall of the energy absorbing block 302. It should be noted that there is a gap between the side wall of the energy absorbing block 302 and the opposite side wall of the energy absorbing box 301, and this gap forms a collapse gap.

[0042] In some embodiments, the cross section of the energy absorbing block 302 is a rectangular surface, and the cross section of the corresponding energy absorbing box 301 is a rectangular surface. The shape of the energy absorbing box 301 can be the same as the shape of the energy absorbing block 302. Of course, the shape of the energy absorbing box 301 can also be different from the shape of the energy absorbing block 302, as long as the distance between the inner wall of the energy absorbing box 301 and the energy absorbing block 302 can be guaranteed.

[0043] In some embodiments, the collapse gap between the energy absorbing block 302 and the energy absorbing box 301 includes but is not limited to being greater than 10 mm.

[0044] The elastic seal 303 is filled between the circumferential side wall of the energy absorbing box 301 and the energy absorbing block 302 , that is, the elastic seal 303 is filled in the collapse gap and is used to connect the energy absorbing block 302 and the circumferential side wall of the energy absorbing box 301 .

[0045] The anti-collision beam in the present application adopts a foam aluminum energy-absorbing block as the energy-absorbing block to realize energy absorption during a vehicle collision, and a collapse gap is set between the energy-absorbing block 302 and the energy-absorbing box 301 to ensure the smooth collapse of the energy-absorbing block 302. The structure is simple; an elastic seal 303 is filled between the energy-absorbing box 301 and the energy-absorbing block 302 to ensure the sealing of the collapse space therebetween, and during the collapse of the energy-absorbing block 302, the elastic seal 303 can be squeezed to ensure the collapse of the energy-absorbing block 302.

[0046] In addition, no collapse structure is provided along the connecting line direction between the anti-collision beam body 100 and the anti-collision beam mounting plate 200. Instead, the space beside the energy-absorbing block is utilized. Therefore, the dimension along the connecting line direction between the anti-collision beam body 100 and the anti-collision beam mounting plate 200 can be reduced, thereby reducing the occupied space.

[0047] In some embodiments, two ends of the energy absorbing block 302 are fixedly connected to the anti-collision beam body 100 and the anti-collision beam mounting plate 200 respectively.

[0048] In an optional embodiment, one end of the energy absorbing block 302 is bonded to the anti-collision beam body 100 , and / or the other end of the energy absorbing block 302 is bonded to the anti-collision beam mounting plate 200 .

[0049] The connection method of the energy absorbing block 302 to the anti-collision beam body 100 and the anti-collision beam mounting plate 200 includes but is not limited to bonding. In some embodiments, the energy absorbing block 302 to the anti-collision beam body 100 and the anti-collision beam mounting plate 200 includes but is not limited to bonding with structural adhesive.

[0050] In some embodiments, both ends of the energy absorption box 301 are fixedly connected to the anti-collision beam body 100 and the anti-collision beam mounting plate 200 respectively.

[0051] It should be noted that the energy absorbing assembly 300 is connected between the anti-collision beam body 100 and the anti-collision beam mounting plate 200, including but not limited to being connected through the energy absorbing box 301 and / or through the energy absorbing block 302. In the present application, the energy absorbing box 301 and the energy absorbing block 302 are both connected to the anti-collision beam body 100 and the anti-collision beam mounting plate 200 to realize the connection of the energy absorbing assembly 300.

[0052] Optionally, one end of the energy absorption box 301 is welded to the anti-collision beam body 100, and / or the other end of the energy absorption box 301 is welded to the anti-collision beam mounting plate 200. The welding method can ensure the stability of the connection, avoid the position of the energy absorption assembly 300 from shifting during the vehicle collision, and ensure the smooth collapse and energy absorption of the energy absorption box 301.

[0053] In some embodiments, the energy absorbing box 301 and the anti-collision beam body 100 and the energy absorbing box 301 and the anti-collision beam mounting plate 200 are welded by carbon dioxide shielded welding. Of course, other welding methods can also be used, and they are all within the protection range.

[0054] See also Figure 5 As shown, the filling height of the elastic seal in the present application in the collapse gap is smaller than the height of the energy absorption box 301 .

[0055] It should be noted that the height of the energy absorption box 301 is the direction of the connection between the anti-collision beam body 100 and the anti-collision beam mounting plate 200 .

[0056] Figure 5 The energy absorbing block 302 shown in the figure is a foam aluminum energy absorbing block, and the foam aluminum energy absorbing block has both metal and bubble characteristics and has a very high impact absorption ability. The shape of the energy absorbing block 302 can be set according to different needs and is within the protection range.

[0057] Combination Figures 6 to 8 As shown, the anti-collision beam mounting plate 200 in the present application has a limiting groove, and the energy absorbing block 302 is limitedly installed in the limiting groove.

[0058] The shape and size of the limiting groove are adapted to the end of the energy absorbing block 302 connected to the anti-collision beam mounting plate 200, and the limiting of the limiting groove can facilitate the installation of the energy absorbing block 302. In addition, under the limiting effect of the limiting groove, the energy absorbing block 302 can be prevented from shifting during the collision process, thereby ensuring the collision energy absorption effect of the energy absorbing block 302.

[0059] In some embodiments, the anti-collision beam mounting plate 200 is provided with limiting ribs 202 , and limiting grooves are formed between the limiting ribs 202 .

[0060] The limiting rib 202 is a protrusion arranged on the anti-collision beam mounting plate 200. The shape and size of the protrusion are not specifically limited. In some embodiments, the limiting rib 202 is a waist-shaped block, and the limiting rib 202 is arranged to form a limiting groove according to the shape of the energy absorbing block 302.

[0061] Figure 8 There are four limiting ribs 202 shown in the figure, and they are arranged in a rectangular shape.

[0062] By providing the limiting ribs 202 to form the limiting grooves, the energy absorbing block 302 can be limited on the one hand, and the strength of the anti-collision beam mounting plate 200 can be increased on the other hand.

[0063] In other embodiments, a limiting groove may be dug on the anti-collision beam mounting plate 200 , but the digging method can reduce the volume.

[0064] Those skilled in the art can set the depth of the limiting groove according to different needs, and all of them are within the protection range.

[0065] Combination Figure 8 As shown, the energy absorbing block 302 is arranged in the limiting groove surrounded by the limiting rib 202, and the energy absorbing box 301 is located at the outer ring of the limiting rib 202, that is, the limiting rib 202 is located between the energy absorbing box 301 and the energy absorbing block 302, that is, the limiting rib 202 is located in the collapse gap. The limiting rib 202 is a convex rib arranged on the plate body 201 of the anti-collision beam mounting plate 200.

[0066] Combination Figure 2 and Figure 3 As shown, the anti-collision beam body 100 and the energy absorbing assembly 300 are connected via a connecting plate 101 , wherein the connecting plate 101 is welded to the anti-collision beam body 100 , and the connecting plate 101 is welded to the energy absorbing box 301 , and the energy absorbing block 302 is bonded to the connecting plate 101 .

[0067] In the present application, the connection plate 101 can increase the bonding stability of the energy absorbing block 302, and the size and material of the connection plate 101 are not specifically limited.

[0068] It should be noted that in order to ensure the smooth energy absorption of the energy absorption assembly 300, the energy absorption box 301 is a thin-walled structural member. The thickness of the energy absorption box 301 can be set according to different needs, as long as the energy absorption box 301 can collapse when the collision force of the vehicle reaches a preset value.

[0069] The elastic sealing members involved in this article include but are not limited to foam glue. The foam glue is used to fill the space between the energy absorbing box 301 and the energy absorbing block 302. On the one hand, it can realize the sealing of the collapse space, and on the other hand, it can also realize the connection between the energy absorbing box 301 and the energy absorbing block 302. In addition, during the collapse of the energy absorbing block 302, the foam glue will not affect the collapse of the energy absorbing block 302.

[0070] In addition, the present application also discloses a vehicle, including an anti-collision beam, wherein the anti-collision beam is the anti-collision beam disclosed in the above embodiment. Therefore, the vehicle with the anti-collision beam also has all the above technical effects, which will not be repeated here one by one.

[0071] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
