Embodiment

[0025] Such as figure 1 with figure 2 As shown, a high-strength vehicle body structure includes a body 1 and an underframe 2 rigidly welded to the body 1, wherein the body 1 includes an engine cover 11, a front fender 12, a roof cover 13, and a rear fender 14 and a trunk lid 15; the underframe 2 is a frame structure formed by fixed connection of multi-section high-strength underframe steel pipes, and is fixedly installed on the bottom of the body 1 through a plurality of installation points; the underframe steel pipes are at room temperature High-strength bake-hardened steel pipe with a lower tensile strength of 400-600MPA.

[0026] The chassis 2 includes a first trapezoid 21, a second trapezoid 22, a third trapezoid 23, a fourth trapezoid 24, a fifth trapezoid 25 and a sixth trapezoid 26 which are welded rigidly to the first trapezoid in sequence; The structural unit is a welded triangle.

[0027] Specifically, the lower base of the first trapezoid 21 and the lower base o...

Abstract

The invention discloses a high-strength vehicle body structure and relates to the field of vehicle body design. The high-strength vehicle body structure comprises a body and a chassis in rigid weldingconnection with the body. The body comprises an engine hood, a front fender, a vehicle top cover, a rear fender and a trunk lid. The chassis is fixedly installed at the bottom of the body through multiple installation points, and the chassis is of a frame structure formed by multiple sections of chassis steel pipes in a fixed connecting mode. The chassis comprises a first trapezoid, a second trapezoid, a third trapezoid, a fourth trapezoid, a fifth trapezoid and a sixth trapezoid, wherein the second trapezoid, the third trapezoid, the fourth trapezoid, the fifth trapezoid and the sixth trapezoid are in rigid welding connection with the first trapezoid sequentially. The minimum structural unit of each trapezoid is a welded triangle. The high-strength vehicle body structure has the beneficial effects of being small in vehicle body mass, low in gravity center, high in space use rate, capable of improving the strength, good in heat insulation effect, safe, resistant to collisions and capable of achieving vehicle body modularization and greatly reducing research and development cost and shortening a research and development period on the premise that different vehicle performance requirements are met.

Description

technical field [0001] The invention relates to the field of vehicle body design, in particular to a high-strength vehicle body structure. Background technique [0002] With the development of the economy, the demand for automobiles is increasing. As an important part of automobiles, the body can enhance the impact resistance of the body. Traditional car bodies are mainly divided into two types: non-load-bearing and load-bearing. A car with a non-load-bearing body has a rigid frame, also known as a chassis frame. The body body is suspended on the vehicle frame and connected by elastic elements. The vibration of the frame is transmitted to the body through elastic elements, and most of the vibration is weakened or eliminated. When a collision occurs, the frame can absorb most of the impact and protect the body when driving on bad roads, so the deformation of the car is small and stable. Good performance and safety, and low noise in the cabin, but this kind of non-load-bear...
