Abstract
The utility model discloses a high-strength steel frame structure and a car body. The high-strength steel frame structure comprises an A column upper inner plate, an A column reinforcing plate and a threshold inner plate. The A column upper inner plate and the threshold inner plate are fixedly arranged at the upper top end and the lower top end of the A column reinforcing plate so as to form an n-shaped structural frame. The structure has good counter bending performance, anti-torsion performance and impact resistant capacity and has better safety performance at collision time. Generally, when a collision occurs, collision force is directly transmitted backward from a send cabin longitudinal beam, and is transmitted through three paths when reaching the floor, wherein the three paths are respectively an A column, a threshold and a base plate longitudinal beam. Through the structure, the hinge strength is effectively improved, the counter bending performance is improved, the broadcast of force is ensured, and the safety collision performance is improved.
Description
Technical field

Background technology
At present, along with Chinese automobile develop rapidly, automobile per capita recoverable amount is more and more, collision safety performance has been subject to extensive concern.The bus body strength collision performance of automobile is most important, and car body is the skeleton of whole automobile, and car load collision contribution rate, more than 60%, has important effect so improve the intensity of body in white to collision safety performance.
The method that improves body in white intensity is to be mainly to increase panel beating thickness and replace two kinds of methods of high strength panel beating material, but improve panel beating thickness and can increase complete vehicle weight, affect fuel utilization ratio, thickness increases simultaneously directly affects feasibility of welds, and effect is not clearly.Still will replace high-strength plate to high-end car increases car body strength, but this kind of method reduces waste, needs research staff to want System Thinking, designs a kind of organization plan and carrys out the most significantly to increase integral strength.
Which position weak strength solves at present car body intensity scheme is mainly, just increase local strength at this region switching high strength steel and meet car body performance, but high strength steel is because intensity is large, so forming ability is poor, without these materials of use of planning cause later stage technique to realize difficulty large, debugging cycle is long, is even sometimes limited by manufacture and cannot directly switches high strength material and make up intensity.In addition mixed and disorderly unordered gaining in strength and greatly cause the waste of resource with high strength steel of later stage, cost is increased, although supplemented local strength, but there is no the intensity of the whole vehicle body of maximum lift, does not have high strength steel performance actv. to be used.
Utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of high strength steel framed structure and vehicle body.Carry out optimum raising integral strength and collision performance by design high strength steel framed structure, high strength steel framed structure is applied in the actual conditions of the collision of consideration vehicle body and bus body strength key area increases bus body strength, and the complexity simultaneously realizing according to technique is carried out rational deployment to high strength steel framed structure.
The utility model is achieved through the following technical solutions:
A kind of high strength steel framed structure, this high strength steel framework comprises inner panel on A post, A column reinforcement plate, threshold inner panel; Inner panel on described A post, A column reinforcement plate, threshold inner panel is fixedly installed on the He Xia top, upper top of described A column reinforcement plate, and forms " several " shape structural framing.
Preferably, on described A post, inner panel, A column reinforcement plate and threshold inner panel are to be made up of high-strength B400/780DP Steel material.
Preferably, on described A post, inner panel, A column reinforcement plate and threshold inner panel are welding.
