Automobile longitudinal girder reinforcement of the present invention comprises base plate, in base plate forward edge, is provided with also vertical front vertical plate upward of one connection, is provided with one connects also vertical back vertical plate upward in base plate posterior edges; Described stringpiece reinforcement is also provided with also vertical left riser upward of one connection in base plate left side edge, is provided with one connects also vertical right riser upward in base plate right side edge; In the left side edge of described front vertical plate, the left side edge of back vertical plate, be respectively equipped with the left turnover panel that bends towards left riser, described left turnover panel and left riser stack and are welded and fixed; In the right side edge of described front vertical plate, the right side edge of back vertical plate, be respectively equipped with the right turnover panel that bends towards right riser, described right turnover panel and right riser stack and are welded and fixed.
Further, described left turnover panel is stacked in the outside of left riser, and right turnover panel is stacked in the outside of right riser.
Further, on the front vertical plate of this stringpiece reinforcement, right riser, be respectively equipped with positioning boss.
Further, be provided with along the reinforced rib of front and back side direction on the base plate of this stringpiece reinforcement, described Jia Qiang Zhu can strengthen horizontal anti-bending strength and the intensity of stringpiece reinforcement.
A kind of automobile longitudinal girder of the present invention, its section takes the shape of the letter U, and strengthens position weld above-mentioned stringpiece reinforcement in the U-lag domestic demand of this longeron, and the front vertical plate of described stringpiece reinforcement, back vertical plate weld with the groove inwall of automobile longitudinal girder respectively.
The groove inner wall depression that positioning boss on described stringpiece reinforcement and described automobile longitudinal girder need be strengthened position matches, and makes stringpiece reinforcement can accurately navigate to corresponding position.
The present invention has the following advantages: described stringpiece reinforcement has base plate and riser all around, and the turnover panel bending by forward and backward riser stacks and is welded and fixed with left and right riser respectively, thereby form the box like structure stringpiece reinforcement that opening is arranged at a top, by two inwall laminating welding of groove of riser before and after it and automobile longitudinal girder, compare with existing U-shaped reinforcement, the intensity of box like structure of the present invention is higher, also on base plate, increase cross reinforcing simultaneously, further improved bending strength.
Automobile longitudinal girder of the present invention is owing to having adopted described box like structure stringpiece reinforcement, its intensity is high, anti-bending strength is good, can guarantee in high-speed crash operating mode, can there is not bending distortion in automobile longitudinal girder root, effectively reduce vehicle body front structure to the intrusion amount of occupant space, improve collision safety performance.
In addition, of the present invention simple in structure, adopting increase stringpiece reinforcement thickness and the number of plies to put forward high-intensity mode with tradition compares, the present invention can save material cost significantly carrying the high-intensity while, and owing to need not increasing thickness and the number of plies of stringpiece reinforcement, it can effectively reduce welding process difficulty, improves welding precision and is welded into power.
