Anti-rollover passenger car frame

Abstract

The invention discloses an anti-rollover passenger vehicle skeleton and a processing technology thereof, and belongs to the technical field of the vehicle safety. The structure comprises a chassis and a vehicle body, wherein the chassis and the vehicle body are assembled and combined with the skeleton into a whole; the skeleton comprises a keel positioned on the chassis; and the keel is surrounded in the vehicle body along the radial direction of the vehicle body to be combined with the chassis to form a closed frame. Therefore, in the anti-rollover process of a vehicle, the keel and the chassis mutually perform the action on supporting the skeleton to prevent the vehicle body from being extruded, the life safety of passengers is effectively guaranteed, and the vehicle safety is improved. The processing method comprises the following steps: drawing lines on a plate, cutting and baiting, rolling and homogenizing, machining and forming, combining, and assembling and welding.

Description

technical field [0001] The invention relates to an automobile safety structure, in particular to an anti-rollover passenger car skeleton with a rollover protection structure capable of effectively protecting the car body when a side collision occurs to the car and its processing technology. Background technique [0002] Safety performance is one of the important indicators for evaluating car design. For this reason, many designs are designed around car safety devices. For example, adding bumpers to the car body can effectively buffer and absorb the frontal impact of the car; and ESP (Electronic Stability System) is recognized as the best car stability control device. ESP controls the driving stability of the car by controlling the four-wheel braking force distribution to prevent the car from sideways in certain dangerous conditions. Overturning or overturning accidents to avoid casualties and property losses. But this kind of ESP turns when the car exceeds a certain failure...

AI Technical Summary

Problems solved by technology

But this kind of ESP turns when the car exceeds a certain failure speed, the lateral acceleration is large, the wheel adhesion is small, and the braking force is insufficient. The above-mentioned ESP system cannot function normally, causing the car to lose control and easily rollover or Overturning and other accidents

[0003] Existing vehicles, especially the body part of passenger cars are basically shells made of iron sheets and interior layers, and the body structure is relatively thin. Large deformation occurs, squeezes the internal space, and directly squeezes the occupants inside, posing a great threat to the safety of personnel, and similar accidents are staged every day
