Automobile front floor framework

Abstract

The invention provides an automobile front floor framework structure, which has strong integral rigidity, can reduce the compression amount of the living space of passengers when colliding, and protects the safety of the passengers. The automobile front floor framework comprises a framework structure which is in a shape like a Chinese character 'mu' and is formed by overlapping a front beam, a left longitudinal beam and a right longitudinal beam, a left door sill inner plate and a right door sill inner plate as well as a rear beam, wherein the front part of the front beam is overlapped with the left and the right front longitudinal beam, the key point is that the invention further comprises a left middle longitudinal beam and a right middle longitudinal beam as well as a middle beam arranged between the front beam and the rear beam, the front ends of the left and the right middle longitudinal beams are respectively overlapped with the front beam or the left and the right longitudinal beams, and the rear ends thereof are respectively overlapped with the rear beam; and the middle beam is respectively overlapped with the left door sill inner plate, the left longitudinal beam, the left middle longitudinal beam, the right middle longitudinal beam, the right longitudinal beam and the right door sill inner plate along the left and the right directions of a vehicle body. The invention adds the left and the right middle longitudinal beams and the middle beam, effectively enhances the framework, can better absorb the collision energy during the processes of front side collision and side collision, reduces the compression amount of the living space of the passengers, and protects the safety of the passengers.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a vehicle body structure. Background technique [0002] In the traditional body structure, most of the car's front floor frame is composed of left and right front longitudinal beams, left and right longitudinal beams, door sill inner panels and front cross beams. The overall rigidity is insufficient, and it is easy to deform when the vehicle collides. , it is difficult to ensure the living space of the occupants, such as: the front floor is seriously deformed during the front collision, and the intrusion of the firewall is too large, which poses a serious threat to the calf of the driver and the front passenger; If it is too large, the structure of the passenger compartment will be seriously deformed. Contents of the invention [0003] The purpose of the present invention is to propose a car front floor frame structure with strong overall rigidity,...
