The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 2, the present embodiment provides an instrument panel beam assembly, including a beam 100, a steering column mounting bracket 231 mounted on the beam 100, and at least one side bracket 220, wherein the beam 100 is connected to two sides of a vehicle body through the at least one side bracket 220, and the steering column mounting bracket 231 is disposed corresponding to a main driving position of the vehicle; the vehicle body support structure further comprises a central support 210 mounted on the beam body 100, wherein the central support 210 is used for supporting the beam body 100 in a first direction X and a second direction Y, the first direction X is the front-rear direction of the vehicle, and the second direction Y is the height direction of the vehicle. Through optimizing structural design, avoided among the correlation technique the design defect of the support that plays supporting role to roof beam body 100, make the size of installing in the central authorities support 210 of roof beam body 100 littleer, lightened the weight of central authorities support 210, and then can lighten the weight of instrument board crossbeam assembly to satisfy body construction's lightweight requirement.

In which the second end 213 of the center bracket 210 may be connected to the dash panel 300 of the vehicle body, and the distance between the beam body 100 and the dash panel 300 is short after the dash cross-member assembly is mounted on the vehicle, so that the center bracket 210 can be designed to be smaller in size. On the premise of ensuring the performance of the central support 210, a local hollow structure is adopted, so that further weight reduction is realized.

Referring to fig. 5, in some embodiments, the beam 100 is a tubular structure; since the performance requirement of the beam body 100 corresponding to the primary driving seat of the vehicle is higher than the performance requirement corresponding to the secondary driving seat of the vehicle, the thickness of the pipe wall 101 of the beam body 100 corresponding to the primary driving seat of the vehicle is greater than the thickness of the pipe wall 102 corresponding to the secondary driving seat of the vehicle. Thus, by optimizing the structural design of the beam body 100, a significant weight reduction can be achieved while ensuring performance.

In this embodiment, the beam body 100 may also be referred to as a tubular beam.

In some embodiments, the beam body 100 is made of carbon fiber material through a layup process, wherein a layup thickness of the carbon fiber material of the beam body 100 corresponding to a main operator's seat of the vehicle is greater than a layup thickness of a secondary operator's seat. With such an arrangement, the beam body 100 can be reduced in weight while the structural performance of the beam body 100 is ensured by the excellent specific stiffness and specific modulus of the carbon fiber material.

In this embodiment, the beam body 100 may be made of carbon fiber materials of different brands and manufacturers through a layering process, for example, T300 type carbon fiber with a unidirectional tape thickness of 0.2mm and/or T700 type carbon fiber with a unidirectional tape thickness of 0.15mm may be used, and compared with the T300 type carbon fiber, the T700 type carbon fiber has a higher mass fraction of carbon and a better tensile strength. By adopting a plurality of layers of carbon fiber composite materials with the same or different brands for compression molding and laying different quantities of carbon fiber composite materials or different thicknesses on the substrate, the beam body 100 with the beam wall thickness of 2 mm-2.5 mm can be formed, the thickness of the beam wall can be designed to be 2mm, 2.05mm, 2.35mm or 2.5mm, and the beam body 100 with the thicker beam wall can meet higher performance requirements. The cross-section of the beam body 100 may be rectangular, and the length and width dimensions of the cross-section may be 50mm by 50 mm.
