Abstract
The invention discloses a front auxiliary frame structure combined by dissimilar materials, and belongs to the field of auxiliary frame structures. The front auxiliary frame structure comprises a front auxiliary frame assembly and an anti-collision beam assembly, wherein anti-rotation supports are welded at the two ends of a front cross beam body; one end of each of the two energy absorption boxesis connected with the anti-rotation support through a welding square nut; mounting plates are respectively arranged at the other ends of the two energy absorption boxes; the cross beam body is connected with a front longitudinal beam upper plate through a connecting piece; a front longitudinal beam lower plate is arranged at one end of the front longitudinal beam upper plate; the front longitudinal beam lower plate is fixedly connected with the front auxiliary frame assembly through bolts; mounting holes are formed in the two sides of the anti-collision beam assembly; and the anti-collision beam assembly is fixedly connected with the mounting plates arranged on the energy absorption boxes through the mounting holes in the two sides in cooperation with bolts. The structure is convenient todisassemble and assemble, the manufacturing is easy, the process is easy to achieve, the anti-collision beam assembly and the front longitudinal beam are additionally arranged so as to enable the front auxiliary frame assembly to participate in energy absorption earlier, and thus the anti-collision effect is improved.
Description
technical field [0001] The invention relates to the field of sub-frame structures, in particular to a front sub-frame structure combined with different materials. Background technique [0002] In the platform planning of automobiles, it is necessary to consider a variety of powertrain layouts to enrich product types and improve product competitiveness. The front cabin needs to take into account the powertrain layout of fuel vehicles, plug-in hybrid vehicles, extended-range electric vehicles, and pure electric vehicles. Moreover, the lightweight and electrification of automobiles poses greater technical challenges to the design of automobile collision safety. When the powertrain occupies a large space, the left / right front side beam assembly of the vehicle body will be avoided by the powertrain accordingly, thereby reducing the width of the front side beam of the vehicle body. However, in the current vehicle collision safety design verification, collision safety CAE analysi...
