AI Technical Summary

Technical Problem

The sill design of existing vehicles cannot effectively withstand the impact force when collisions on the front and side, causing passenger safety to be threatened and affecting the safety of the vehicle.

Method used

A vehicle sill assembly is designed to increase the structural strength of the sill beam by providing reinforcement beams in the receiving cavity defined by the sill beam, and to satisfy a specific proportional relationship (0.25K1≤F2≤0.98K1) between the length of the sill beam and the length of the sill cavity.

Benefits of technology

The structural strength of the sill beam is effectively improved, so that it can effectively withstand the impact force when the vehicle is hit by frontal and side, thereby reliably protecting passengers and improving the safety of the vehicle.

Abstract

The utility model discloses a threshold assembly of a vehicle and the vehicle, the threshold assembly of the vehicle comprises: a threshold beam defining an accommodating cavity; the reinforcing beam is arranged in the accommodating cavity; in the first direction of the vehicle, the length of the stiffening beam is F2, the length of the containing cavity is K1, and the relational expression that F2 is larger than or equal to 0.25 K1 and smaller than or equal to 0.98 K1 is met. Therefore, the reinforcing beam is arranged in the containing cavity defined by the doorsill beam, the length F2 of the reinforcing beam and the length K1 of the containing cavity meet the relational expression that 0.25 K1 < = F2 < = 0.98 K1, the structural strength of the doorsill beam can be effectively improved, and therefore when a vehicle is subjected to front collision and side collision, the doorsill beam can effectively bear collision force; therefore, passengers in the passenger compartment of the vehicle can be reliably protected, and the safety of the vehicle can be improved.
