New energy automobile reinforced threshold

Abstract

The invention discloses a reinforced threshold of a new energy automobile, and aims to overcome the defect that the risk of extruding a power battery module exists due to the fact that an existing automobile threshold deforms and intrudes into a battery area when being subjected to side impact. The doorsill comprises a doorsill outer plate, a doorsill inner plate and a doorsill reinforcing structure, the doorsill inner plate is sequentially connected with a seat cross beam, a reinforcing plate and a power battery module from top to bottom, the doorsill outer plate and the doorsill inner plate form a hollow cavity, the doorsill reinforcing structure is arranged in the hollow cavity, and the doorsill reinforcing structure is fixedly connected with the upper portion and the lower portion of the doorsill outer plate. The end, away from the doorsill outer plate, of the doorsill reinforcing structure is arranged at the position corresponding to the seat cross beam and the reinforcing plate, and the doorsill reinforcing structure and the hollow cavity form a collapse cavity. The hollow triangle and the splayed supporting bracket are arranged at the position corresponding to the power battery module, so that the volume of the lower part of the hollow cavity is reduced, the rigidity of the hollow cavity is reduced, the crumple space of the hollow cavity is increased, and a battery area is prevented from being invaded.

Description

technical field [0001] The invention relates to the field of automobile body production, more specifically, it relates to a new energy automobile reinforced threshold. Background technique [0002] For traditional vehicles of the same level, new energy vehicles usually weigh 200kg~300kg or more, which leads to a significant increase in the collision energy in the vehicle side column collision condition, thereby increasing the risk of collision safety. At the same time, in order to increase the cruising range of new energy vehicles, the battery size often covers the entire floor, resulting in a small safety space from the battery module to the sill beam. This will lead to a side collision of the vehicle, especially a side pillar collision, excessive intrusion of the threshold, extrusion of the power battery module, and a greater electrical safety risk. The traditional automobile door sill beam reinforcement structure generally adopts a steel reinforcement box structure, or a...

AI Technical Summary

Problems solved by technology

During the side pillar impact process, the threshold of the vehicle is seriously deformed, and there is a risk of squeezing the power battery module, which makes it difficult to meet the electrical safety requirements of new energy vehicles.
