Body anti-collision structure

Abstract

The invention provides a vehicle body side-collision-resistance structure. The vehicle body side-collision-resistance structure comprises a floor, a doorsill, a seat mounting cross beam, a side-collision-resistance supporting plate and a seat mounting bracket. The doorsill comprises a side plate and an upper plate. The side-collision-resistance supporting plate is separately and fixedly connectedwith the upper plate and the seat mounting cross beam, and the side-collision-resistance supporting plate forms a first cavity structure together with the side plate and the seat mounting cross beam;and the seat mounting cross beam forms a second cavity structure together with the floor and the side plate of the doorsill, and the seat mounting bracket is fixed to the side-collision-resistance supporting plate and forms a third cavity structure together with the side-collision-resistance supporting plate. Since the large side-collision-resistance supporting plate is adopted, the supporting strength of the side-collision-resistance supporting plate is strengthened, the supporting area is increased, and the force is dispersed. Through the design of the first cavity structure, the second cavity structure and the third cavity structure, impact kinetic energy can be absorbed, the safety of a driver cabin in a vehicle is protected, and the side-collision-resistance performance of a vehicle body is effectively improved.

Description

technical field [0001] The present application relates to the technical field of automobile body, in particular to an anti-side collision structure of the vehicle body. Background technique [0002] With the development and progress of the automobile industry, the relevant national crash test regulations have become more perfect and stricter, and consumers are paying more and more attention to automobile safety. For example, China's new car evaluation standards put forward stricter and more comprehensive requirements for the evaluation standards of crash safety performance tests for new models on the market than my country's existing mandatory standards. Therefore, when designing a car body, the protection of the occupants in the car should be the first priority, and every effort must be made to minimize the deformation of the cab in the event of a car collision, so as to minimize the damage to the occupants in the car. [0003] Side impact is a very important part of safet...

Problems solved by technology

On the one hand, it is because the size of the anti-side-collision overturn support plate 50 is small, and the effect of absorbing the side-collision impact force is limited.

On the other hand, since the anti-side impact support plate 50 is only lapped on the upper plate 202 of the inner door sill 20 and does not have any fixed contact with the side plate 201 of the inner door sill 20, the inner door sill 20 will The impact force is transmitted to the floor 10 and the anti-side collision support plate 50, and the anti-side collision support plate 50 transmits the impact force to the seat mounting bracket, thereby making the seat mounting bracket 40 at the stress terminal , easy to deform, once the seat mounting bracket 40 is deformed, the seat on it will be tilted, affecting the safety of drivers and passengers

Therefore, this structure still can not solve the safety hazard that automobile body produces because of side collision
