Passenger vehicle front floor framework structure

Abstract

The invention discloses a passenger vehicle front floor framework structure. A left longitudinal beam connection plate cover plate is arranged above a front floor and corresponds to a left longitudinal beam connection plate, the left end of the left longitudinal beam connection plate cover plate is connected with a front floor left inner longitudinal beam cover plate corresponding to a left inner longitudinal beam, and the middle of the left longitudinal beam connection plate cover plate is connected with a second left inner longitudinal beam cover plate corresponding to a second left inner longitudinal beam. A right longitudinal beam connection plate cover plate is arranged above the front floor and corresponds to a right longitudinal beam connection plate, the right end of the right longitudinal beam connection plate cover plate is connected with a front floor right inner longitudinal beam cover plate corresponding to a right inner longitudinal beam, and the middle of the right longitudinal beam connection plate cover plate is connected with a second right inner longitudinal beam cover plate corresponding to a second right inner longitudinal beam. Reinforcing parts are ingeniously added above the floor, the longitudinal rigidity of a front floor framework beam and the strength of a front bracket rear installation point are improved, the deformation amount of the inner longitudinal beams in the collision process and the backward movement amount of the front bracket rear installation point are decreased, a living space of passengers is further enlarged, and the head-on collision performance of a passenger vehicle is improved.

Description

technical field [0001] The invention relates to the vehicle body floor technology of a passenger car, in particular to a front floor frame structure of a passenger car. Background technique [0002] Safety is an important concern in the process of automobile research and development. Ensuring the safety of occupants during collisions is the consistent pursuit of the automobile industry. Among them, improving the collision performance of the front floor structure is one of the important means to improve automobile safety. At present, since the installation point of the front bracket is on the front side beam and the side beam connecting plate of the vehicle body, the deformation of the front side beam during the frontal collision drives the deformation of the side beam connecting plate and the inner side beam of the front floor through the front bracket, resulting in During the frontal collision, the deformation of the inner longitudinal beam of the floor and the rearward mov...

Problems solved by technology

At present, since the installation point of the front bracket is on the front side beam and the side beam connecting plate of the vehicle body, the deformation of the front side beam during the frontal collision drives the deformation of the side beam connecting plate and the inner side beam of the front floor through the front bracket, resulting in During the frontal collision, the deformation of the inner longitudinal beam of the floor and the rearward movement of the rear mounting point of the front bracket increase, which makes the front floor seriously deformed during the frontal collision, and the occupant's living space is insufficient, which in turn causes the driver's head, chest, and thighs are vulnerable to injury
