Wherein, crashproof roof beam body 1 and two energy-absorbing boxes 2 integrated into one piece.

According to the anti-collision beam 100 disclosed by the embodiment of the disclosure, the anti-collision beam body 1 and the two energy-absorbing boxes 2 are integrally formed, so that a welding process for welding the anti-collision beam body 1 and the energy-absorbing boxes 2 can be canceled, and the production efficiency of the anti-collision beam 100 can be improved. In addition, after the welding process is canceled, performance attenuation caused by a heat affected zone in the welding process can be avoided, and the collision performance of the anti-collision beam 100 can be improved.

Accordingly, the impact beam 100 of the embodiment of the present disclosure has advantages such as high production efficiency.

For example, the crashproof beam body 1 and the energy-absorbing box 2 are integrally extruded by aluminum profiles.

The anti-collision beam body 1 and the energy absorption box 2 are integrally extruded and formed, so that the anti-collision performance of the anti-collision beam 100 is further improved, and the manufacturing cost of the anti-collision beam 100 is reduced.

Of course, in other embodiments, the impact beam body 1 and the energy absorber box 2 may be integrally formed by other processes, for example, the impact beam body 1 and the energy absorber box 2 may be integrally die-cast.

Optionally, the anti-collision beam body 1 and the energy absorption box 2 are made of aluminum alloy materials.

The anti-collision beam body 1 and the energy absorption box 2 are made of aluminum alloy materials, so that the weight of the anti-collision beam 100 can be effectively reduced.

Alternatively, as shown in fig. 1, the impact beam 100 is symmetrically arranged in the height direction of the impact beam body 1.

In order to make the technical solution of the present disclosure easier to understand, the technical solution of the present disclosure will be further described below by taking the case that the height direction of the impact beam body 1 coincides with the up-down direction. The up-down direction is shown in fig. 1 and 2.

For example, as shown in fig. 1, the impact beam 100 is symmetrically arranged in the up-down direction. In other words, the upper and lower portions of the impact beam 100 are symmetrically arranged.

By arranging the anti-collision beams 100 symmetrically along the height direction of the anti-collision beam body 1, the anti-collision beam 100 is convenient to process and manufacture, and the stress stability of the anti-collision beam 100 is improved, so that the manufacturing cost of the anti-collision beam 100 is further reduced, and the collision performance of the anti-collision beam 100 is improved.

The left-right direction is shown in fig. 1 to 3.

For example, as shown in fig. 1 and 3, the impact beam 100 is symmetrically arranged in the left-right direction. In other words, the left and right portions of the impact beam 100 are symmetrically arranged.

By arranging the anti-collision beams 100 symmetrically along the length direction of the anti-collision beam body 1, the anti-collision beam 100 is convenient to process and manufacture, and the stress stability of the anti-collision beam 100 is improved, so that the manufacturing cost of the anti-collision beam 100 is further reduced, and the collision performance of the anti-collision beam 100 is improved.

In some embodiments, as shown in fig. 2 and 3, the impact beam body 1 has a first cavity 11, and a first reinforcing rib 12 integrally formed with the impact beam body 1 is disposed in the first cavity 11. In other words, the anti-collision beam body 1 has a first cavity, the first cavity is provided with the first reinforcing rib 12, and the first reinforcing rib 12 and the anti-collision beam body 1 are integrally formed.

For example, as shown in fig. 1 and 2, the first chamber 11 penetrates the impact beam body 1 in the up-down direction, and the first reinforcing rib 12 and the impact beam body 1 are integrally extruded.

By arranging the first cavity 11 on the anti-collision beam body 1, the weight and the material consumption of the anti-collision beam body 1 can be effectively reduced; by arranging the first reinforcing ribs 12 in the first cavity 11, the structural strength of the anti-collision beam body 1 can be effectively improved.

The plurality of first reinforcing ribs 12 are divided into a plurality of reinforcing rib groups, which are sequentially arranged in the left-right direction such that the plurality of first reinforcing ribs 12 form a mesh-like structure.

The arrangement of the plurality of first reinforcing ribs 12 can more effectively improve the structural strength of the impact beam body 1, thereby more effectively improving the structural strength of the impact beam 100.

Of course, in other embodiments, the number of the first reinforcing ribs 12 may be set as needed, for example, the number of the first reinforcing ribs 12 is set to one. The arrangement of the first reinforcing ribs 12 may be other as desired. For example, the plurality of first reinforcing ribs 12 are arranged at intervals in the width direction of the impact beam body 1, and the plurality of first reinforcing ribs 12 are each parallel to the width direction of the impact beam body 1.

In some embodiments, as shown in fig. 2 and 3, the crash box 2 has a second cavity 21, and a second stiffener 22 integrally formed with the crash box 2 is disposed in the second cavity 21. In other words, the energy absorption box 2 is provided with a second cavity, the second cavity is internally provided with the second reinforcing rib 22, and the second reinforcing rib 22 and the energy absorption box 2 are integrally formed.

For example, as shown in fig. 2 and 3, the second chamber 21 penetrates the crash box 2 in the up-down direction, and the second reinforcing rib 22 and the crash box 2 are integrally extrusion-molded.

By arranging the second cavity 21 on the energy absorption box 2, the weight and the material consumption of the energy absorption box 2 can be effectively reduced; by providing the second reinforcing ribs 22 in the second chamber 21, the structural strength of the crash box 2 can be effectively improved.

Thereby, while ensuring the structural strength of the crash box 2, it is advantageous to reduce the weight and cost of the crash box 2, thereby further reducing the weight and cost of the impact beam 100.

Optionally, the second stiffener 22 is a stiffener plate.

Alternatively, as shown in fig. 2 and 3, the second reinforcing ribs 22 extend in the width direction of the impact beam body 1.

In order to make the technical solution of the present disclosure easier to understand, the technical solution of the present disclosure will be further described below taking an example in which the width direction of the impact beam body 1 coincides with the front-rear direction. Wherein the front-rear direction is shown in fig. 1 to 3.

For example, as shown in fig. 2 and 3, the second reinforcing ribs 22 extend in the front-rear direction.

The above arrangement of the second reinforcing ribs 22 can more effectively improve the structural strength of the crash box 2, and thus can further improve the structural strength of the impact beam 100.

Alternatively, as shown in fig. 2 and 3, the number of the second reinforcing ribs 22 in the crash box 2 is plural, and the plural second reinforcing ribs 22 in the same crash box 2 are arranged in parallel with each other.

For example, as shown in fig. 2 and 3, the plurality of second reinforcing ribs 22 are each arranged parallel to the front-rear direction.

The above arrangement of the second reinforcing ribs 22 can more effectively improve the structural strength of the crash box 2, and thus can further improve the structural strength of the impact beam 100.

Of course, in other embodiments, the number of the second reinforcing ribs 22 may be set as desired, for example, the number of the second reinforcing ribs 22 in each of the crash boxes 2 is set to one. The arrangement of the second reinforcing ribs 22 may be other as desired. For example, the plurality of second reinforcing ribs 22 in the same crash box 2 are arranged in a grid.

In some embodiments, as shown in fig. 1 and 2, the dimension of the crash box 2 in the height direction of the impact beam body 1 is greater than the height of the impact beam body 1.

For example, as shown in fig. 1 and 2, the outer peripheral profiles of the impact beam body 1 and the crash box 2 are each in the shape of a cube. In the up-down direction, the height of the energy absorption box 2 is larger than that of the anti-collision beam body 1.

The size of the energy-absorbing box 2 in the height direction of the anti-collision beam body 1 is larger than the height of the anti-collision beam body 1, so that the size of the energy-absorbing box 2 is larger, the energy-absorbing effect of the energy-absorbing box 2 is improved, and the anti-collision performance of the anti-collision beam 100 is further improved.

In some embodiments, as shown in fig. 1 to 3, the impact beam body 1 has two beam end faces 13 disposed opposite each other in the length direction thereof, and each of the crash boxes 2 has a box end face 23 disposed opposite the other crash box 2. Each box end face 23 is provided between two beam end faces 13 in the longitudinal direction of the impact beam body 1.

For example, as shown in fig. 1 and 3, the impact beam body 1 has two beam end faces 13 that are oppositely disposed in the left-right direction. The energy absorption box 2 on the left side is provided with a box end surface 23 which is arranged away from the energy absorption box 2 on the right side; the crash box 2 on the right has a box end face 23 which is arranged facing away from the crash box 2 on the left. Namely, the left end face of the energy absorber 2 on the left side and the right end face of the energy absorber 2 on the right side are both the box end faces 23. The beam end face 13 on the left is disposed on the left of the box end face 23 of the energy absorber 2 on the left, and the beam end face 13 on the right is disposed on the right of the box end face 23 of the energy absorber 2 on the right.

This contributes to further improving the collision performance of the impact beam 100.

In other embodiments, the beam end face 13 on the same side in the longitudinal direction of the impact beam body 1 is flush with the box end face 23.

For example, the impact beam body 1 has two beam end faces 13 disposed opposite to each other in the left-right direction. The energy absorption box 2 on the left side is provided with a box end surface 23 which is arranged away from the energy absorption box 2 on the right side; the crash box 2 on the right has a box end face 23 which is arranged facing away from the crash box 2 on the left. Namely, the left end face of the energy absorber 2 on the left side and the right end face of the energy absorber 2 on the right side are both the box end faces 23. The beam end face 13 on the left and the box end face 23 of the energy absorber box 2 on the left are coplanar, and the beam end face 13 on the right and the box end face 23 of the energy absorber box 2 on the right are coplanar.

This contributes to further improving the collision performance of the impact beam 100.
