Principle of work of the present utility model is: the structure that the outside plate body of the roof rail of A post and cross-beam connecting plate are formed in one, this construction increases the intensity of roof rail, the bending degree of roof rail during frontal crash of vehicles can be effectively reduced, ensure the structural soundness of crew module; The outside plate body of this roof rail is fixedly connected with automobile roof front beam by cross-beam connecting plate, compares the structure that roof rail is directly connected with automobile roof front beam, has larger intensity, because cross-beam connecting plate serves booster action.Cross-beam connecting plate and outside plate body are integrated structures, have better stiffening effect than the brace panel be fixed on roof rail with welding manner or bolt connecting mode.
In the roof rail of above-mentioned a kind of automobile A column, cross-beam connecting plate is fixed with reinforced rib one, the outer end of described cross-beam connecting plate is free end, and the inner of cross-beam connecting plate is connected on outside plate body, and described reinforced rib one extends to the inner of cross-beam connecting plate from the outer end of cross-beam connecting plate.Cross-beam connecting plate arranges reinforced rib one, improves the intensity of cross-beam connecting plate, further increase the Joint strenght of roof rail and automobile roof front beam.
In the roof rail of above-mentioned a kind of automobile A column, reinforced rib one is 2-4 bar, and each reinforced rib one is arranged on cross-beam connecting plate side by side.Reinforced rib one quantity is more, and the intensity of cross-beam connecting plate is higher.
In the roof rail of above-mentioned a kind of automobile A column, the middle part of outside plate body is fixed with protruding reinforced rib two, and described reinforced rib two is arranged along the length direction of outside plate body.Protruding reinforced rib two is set in the middle part of outside plate body, the intensity of outside plate body can be improved, make outside plate body have better shock resistance, when automobile generation head-on crash, roof rail can be reduced and to be impacted the distortion produced.
In the roof rail of above-mentioned a kind of automobile A column, automobile comprises A post, B post and C post, and front end and the automobile A column of described outside plate body are connected, rear end and the automotive C column of outside plate body are connected, middle part and the automobile B-column of outside plate body are connected, and the front end of outside plate body curves inwardly, and outside plate body is curved.The outside plate body of roof rail is arc, and roof rail bending distortion in frontal crash of vehicles process, can absorb collision energy by actv., play the effect of damp impacts power, thus improve the safety performance of car load.
Compared with prior art, advantage of the present utility model is as follows:
1, the structure that is formed in one of the outside plate body of roof rail of the present utility model and cross-beam connecting plate, the bending degree of A post roof rail when this structure can effectively reduce head-on crash, ensure the structural soundness of crew module, optimize the Path of Force Transfer at vehicle body top during central collision; The outside plate body of roof rail is fixedly connected with automobile roof front beam by cross-beam connecting plate, adds the Joint strenght of roof rail and automobile roof front beam, ensure that the integraty of Path of Force Transfer.
2, the outside plate body of roof rail of the present utility model is fixed with protruding reinforced rib two, improves the intensity of outside plate body, makes outside plate body have better shock resistance, when automobile generation head-on crash, can reduce roof rail and to be impacted the distortion produced.
3, the outside plate body of roof rail of the present utility model is arc, and in frontal crash of vehicles process, roof rail produces bending distortion, can absorb collision energy by actv., play the effect of damp impacts power, thus improve the safety performance of car load.
