AI Technical Summary
Technical Problem
Existing technologies increase rigidity by increasing the thickness of floor components, which leads to an increase in floor mass and affects vehicle energy consumption.
Method used
The design incorporates a hollow first and second crossbeam assembly, which, together with the first and second sill assemblies, form a reinforcing cavity to enhance structural rigidity. Furthermore, the overall rigidity of the floor assembly is reinforced by protruding reinforcing ribs and connecting supports.
Benefits of technology
Without significantly increasing the mass of the floor assembly, the torsional stiffness and crash safety performance of the floor assembly were improved, while vehicle energy consumption was reduced.

Abstract
This disclosure relates to a floor assembly and a vehicle, belonging to the field of vehicle engineering technology. The vehicle floor assembly includes a floor, a first crossbeam assembly, a second crossbeam assembly, a first sill assembly, and a second sill assembly. The first and second crossbeam assemblies are arranged parallel to each other on the top surface of the floor, and both are hollow structures. The first sill assembly is located on a first side of the floor and is connected to a first end of the first crossbeam assembly and a first end of the second crossbeam assembly, respectively. The second sill assembly is located on a second side of the floor and is connected to a second end of both the first and second crossbeam assemblies, respectively. A reinforcing cavity is formed between the first crossbeam assembly, the second crossbeam assembly, the first sill assembly, and the second sill assembly. This disclosure effectively improves the structural stiffness of the floor assembly and enhances the force transmission effect during a collision.
