Force transmission structure for vehicle frontal impact along side door windowsill line direction

Abstract

The invention aims to provide a force transmission structure for vehicle frontal impact along the side door windowsill line direction. The structure has simple structure and low cost and can greatly enhance the vehicle frontal impact safety. The structure is characterized in that an A column inside support is arranged in an A column cavity of the vehicle; a B column inside support is arranged in a B column cavity of the vehicle; a front door reinforcing plate is arranged on a front door windowsill line; a back door reinforcing plate is arranged on a back door windowsill line; a front upper longitudinal beam of the vehicle is positioned on the same straight line with the A column inside support, the front door reinforcing plate, the B column inside support and the back door reinforcing plate. The structure can effectively decompose and transmit the frontal impact force to the back of the vehicle during vehicle frontal impact by arranging the A column inside support and the B column inside support in the specific positions, reduce the possibility of A column buckling and tearing of solder joints on the lower part of the A column and avoid the head board and the steering wheel from moving backward, thus improving the vehicle frontal impact safety.

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] With the development of technology, consumers have higher and higher requirements for the collision safety performance of the whole vehicle. Correspondingly, the new vehicle safety assessment of insurance companies and relevant institutions and national and regional regulations have requirements for the collision safety performance of the vehicle body. It is also getting stricter. When a car has a frontal collision, the front impact force is concentrated on the front fender and the A-pillar, which cannot be transmitted in time. Therefore, it is easy to cause the structure or components of the car, such as the A-pillar, front fender and steering wheel, to move backward, thereby oppressing the occupants. , resulting in injury to the occupants. In order to solve this problem, many automobile manuf...

AI Technical Summary

Problems solved by technology

When a car has a frontal collision, the front impact force is concentrated on the front fender and the A-pillar, which cannot be transmitted in time. Therefore, it is easy to cause the structure or components of the car, such as the A-pillar, front fender and steering wheel, to move backward, thereby oppressing the occupants. , causing the occupants to be injured

In order to solve this problem, many automobile manufacturers have to use higher strength materials to manufacture structures such as A-pillars and front fenders, which greatly increases the cost of automobiles.
