Description

Double-beam structure of automobile front wall plate

Technical Field

The utility model relates to a double-beam structure of an automobile front surrounding plate, and belongs to the field of automobile processing.

Background

Automobile crash safety regulations are becoming more and more stringent and are an extremely important concern. The energy absorption, deformation resistance and collision force transmission routes of the automobile body are also increasingly important for protecting passengers in the automobile. In the current automobile design, in order to meet the requirements of front safety collision regulations, when an automobile is prevented from collision, a power assembly and electric devices in a cabin invade a front coaming, so that the front coaming is seriously deformed, and the living space of passengers is prevented from being influenced; there is therefore a need to pay attention to the structural design of the dash panel assembly. Generally, only one beam structure is designed on the front coaming of the automobile, two sides of the beam structure are welded with the left and right A-pillar inner plates, and the cross section structure of the beam cannot be made redundant due to the limitation of peripheral parts. Therefore, when the automobile collides with the front surface, the power assembly and the electric device move backwards to contact the upper front panel, the front panel assembly can effectively resist the external impact force, the effect is not obvious, and meanwhile, the force transmission route is also not good, so that the front panel is seriously deformed and invaded into the passenger cabin, and the safety of passengers is seriously threatened. In order to more effectively improve collision safety and protect the integrity of the passenger compartment, further optimization is required in the structure of the dash panel single-beam.
