AI Technical Summary

Technical Problem

Traditional automobile sills perform poorly in laterally withstand shear forces, resulting in the sill structure being difficult to effectively resist impacts during large-scale impacts on the side and column impacts, affecting occupants' safety and vehicle integrity.

Method used

A threshold structure including a threshold body and two beam bodies is designed. The threshold body is enclosed by the inner plate of the threshold and the front sill door ring to form an installation cavity. The two beam bodies are installed in the installation cavity to form a cavity structure and enclosed by arcuate grooves to form a reinforcement cavity to enhance the lateral shearing ability of the threshold.

Benefits of technology

Through this design, the sill structure performs significantly improved in lateral shear forces, which can more effectively resist collision impacts, protect occupants safety and reduce vehicle damage.

Abstract

The invention discloses a doorsill structure and an automobile, and relates to the technical field of doorsill structures, the doorsill structure comprises a doorsill body and two beam bodies, the doorsill body comprises a doorsill inner plate and a front pillar door ring, the doorsill inner plate and the front pillar door ring are enclosed to form a mounting cavity, the two beam bodies are mounted in the mounting cavity, and the two beam bodies are connected with the doorsill inner plate and the front pillar door ring. Wherein one beam body is installed on one side, in the first direction, of the other beam body, the two first side ends, deviating from each other in the second direction, of the two beam bodies are connected to the two inner cavity walls, in the second direction, of the installation cavity correspondingly, and cavities are formed in the two beam bodies correspondingly; a plurality of arc-shaped grooves are formed in the two opposite second side ends of the two beam bodies in the first direction. The doorsill outer plate and the doorsill inner plate are replaced by the front supporting column door ring to form the doorsill body, the strength of the doorsill structure is enhanced, the aluminum beam assembly is arranged in the mounting cavity formed by the front supporting column door ring and the doorsill inner plate, and the lateral shear force bearing capacity of the doorsill structure is enhanced.
