The present disclosure proposes an instrument panel reinforcement beam. Referring to FIGS. The second brackets 2 are respectively arranged along the first direction, the part of the first bracket 1 is connected with the second bracket 2, and forms a box-like structure 5 with the second bracket 2, and this part of the first bracket 1 is close to one end of the first bracket 1 , the other end of the first bracket 1 is used to connect with the body floor; the main beam 3 and the sub-beam 4 are arranged along the second direction, and the end of the main beam 3 close to the sub-beam 4 passes through the end of the sub-beam 4 close to the main beam 3 The box-like structure 5 is connected.

Compared with the case where the main beam 3 and the sub-beam 4 are welded together, the box-shaped structure can increase the rigidity of the connection between the main beam 3 and the sub-beam 4, so that not only the auxiliary strengthening effect of the sub-beam 4 can be enhanced, but also the instrument panel can be strengthened Strengthen the stiffness of the beam, thereby improving the modal of the steering system and the stiffness of the steering system, thereby improving the quality of the steering wheel modal and idling vibration of the vehicle.

Specifically, the instrument panel reinforcement beam is arranged on the vehicle. In this embodiment, the direction of the vehicle is used as a reference. The directions of up and down, left and right, and front and rear of the vehicle are consistent with the direction of the vehicle. The first bracket 1 and the second bracket 2 are arranged along a first direction, which is the up-down direction shown in the figure, that is, the up-down direction (height direction) of the vehicle.

Specifically, the part of the first bracket 1 (the upper part shown in the figure) is connected with the second bracket 2, and forms a box-like structure 5 with the second bracket 2; wherein, the first bracket 1 is arranged along the first direction, and the second bracket 2 The bracket 2 is also arranged along the first direction, and the first bracket 1 is adjacent to the second bracket 2 , so that the adjacent connection part of the first bracket 1 and the second bracket 2 is surrounded by the second bracket 2 to form a box structure 5 . The part of the first bracket 1 connected to the second bracket 2 is close to one end of the first bracket 1, and the other end of the first bracket 1 is used to connect with the vehicle body floor, that is, the part of the first bracket 1 connected to the second bracket 2 Part is close to the upper end of the first bracket 1, and the lower end of the first bracket 1 is connected to the vehicle body floor. Normally, for the convenience of disassembly and installation, the lower end of the first bracket 1 is screwed to the vehicle body floor.

In this embodiment, the specific connection between the first bracket 1 and the vehicle body floor The connection mode may not be limited, and may be specifically set according to actual conditions.

Specifically, the main beam 3 and the sub-beam 4 are arranged side by side and arranged along the second direction.
