Front upright post reinforcing structure of passenger compartment

Abstract

The invention discloses a front upright post reinforcing structure, which comprises a reinforcing element arranged at the inner side of a side wall outer plate of a vehicle, wherein the reinforcing element is in an integral structure and downwards extends in the length direction of an upper edge beam from a front cross beam part of a top cover of the upper edge beam, after the bending, the reinforcing element passes through the front upright post position, is continuously bent and backwards extends in the length direction of a doorsill to the middle position of the doorsill arranged at the front vehicle door section of the vehicle, and a semi-surrounded state is formed at a front vehicle door. When the front upright post reinforcing structure of an automobile passenger compartment is adopted, the intensity of a front upright post can be greatly enhanced, when the lateral collision of the vehicle body structure is generated, the transfer and dispersion efficiency of the collision force is improved, and the passenger compartment deformation is reduced, so the survival space of passengers in the vehicle is ensured.

Description

Technical field [0001] The invention belongs to the field of vehicle body structures and relates to a front pillar structure. Background technique [0002] When a frontal collision of a vehicle occurs, the collision force is transmitted to the passenger compartment through the front cabin structure, partly transmitted to the rear of the car through the floor, and partly transmitted to the roof, doors and thresholds through the front pillars of the passenger compartment. If the strength of the front pillar is insufficient, the structure of the front pillar itself will be deformed too much, which will cause excessive deformation of the upper side beams, IP beams, etc., which will damage the occupant's living space and seriously affect the safety of the occupants in the car. At the same time, the front pillar moves back, which easily causes the door to be deformed too much and locks up, making it impossible for people in the vehicle to escape. Therefore, in a frontal collision, ens...

AI Technical Summary

Problems solved by technology

If the strength of the front pillar is insufficient, the structural deformation of the front pillar itself will be too large, which will cause excessive deformation of the upper side beam, IP beam, etc., resulting in the destruction of the living space of the occupants, seriously affecting the safety of the occupants in the vehicle

At the same time, the front pillar moves backward, which will easily cause the door to be deformed and locked, making it impossible for the occupants to escape.
