Passenger vehicle cab floor reinforcing plate and floor assembly

Abstract

The invention provides a passenger vehicle cab floor reinforcing plate and a floor assembly and relates to the technical field of vehicle body structure. The passenger vehicle cab floor reinforcing plate comprises a reinforcing plate body plate vertically distributed along a vehicle, and a welded flange welded and attached around the body plate according to the molded surface of a cab floor. A swelling structure of the reinforcing plate body plate and the cab floor form an integrated cavity section, rigidity and strength of the cab floor can be effectively improved, NVH performance of the vehicle is effectively improved, the cavity section can improve bending strength of the vehicle when the vehicle is collided from the front side, and the deformation degree of the cab floor during collision is reduced. The passenger vehicle cab floor reinforcing plate is stable in structure, good in forming performance, precise in welding and positioning, convenient to weld and capable of effectively improving NVH performance and collision safety of the vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile body structures, in particular to a floor reinforcement plate and a floor assembly of a cab of a passenger car. Background technique [0002] With the increasing popularity of automobiles, people pay more and more attention to the comprehensive performance of vehicles, including NVH (Noise, Vibration, Harshness, noise, vibration and harshness) performance and safety performance. The ever-increasing vehicle NVH performance and collision regulations have put forward new and higher requirements for the design of automobile bodies. How to improve the structural rigidity and strength of the car body, the reasonable absorption of the collision energy and the control of the deformation and displacement of the cab during the collision process have a huge contribution to the overall performance of the vehicle. [0003] In the common car floor design at present, the floor frame of the cab is basically c...

AI Technical Summary

Problems solved by technology

There is a lack of a complete overlap between the upper cab floor and the central passage, the structural rigidity of the floor assembly is difficult to further improve, and the improvement of NVH performance is limited. At the same time, when the vehicle is subjected to a frontal collision accident, the front end of the cab floor is not strong enough, resulting in deformation of the floor The greater the volume, the greater the risk of serious injury to the driver's leg
